Description

The present invention relates to a unit room for plumbing equipment, and particularly to a unit room for plumbing equipment that can be assembled by watertightly joining a plurality of building materials to each other.

In general, for unit rooms with plumbing equipment such as unit baths and unit shower rooms, building materials such as flooring, wall materials, and ceilings are manufactured in advance at a factory, and these building materials are transported to the construction site. Manufactured using the knockdown method. Unlike ordinary living rooms, unit rooms for plumbing equipment like this require reliable waterproofing, and watertightness must be ensured at the joints of each building material, such as flooring and wall materials. . In conventional unit rooms for plumbing equipment such as unit baths, silicone is applied to the joints after the building materials are joined at the construction site to ensure watertightness at the joints between flooring and wall materials. It is common practice to ensure watertightness of joints by applying adhesive.

Japanese Unexamined Patent Publication No. 10-317502 (Patent Document 1) describes a method for installing an equipment unit and a unit building to which the equipment unit is installed. In this method of installing equipment units, a heated and softened hot melt type sealant is applied to the gap between the equipment unit and the surrounding building members, and this sealant creates a bond between the equipment unit and the surrounding building members. The space between them is sealed.

Japanese Unexamined Patent Publication No. 2016-50431 (Patent Document 2) describes a sealing method between a floor and a wall in a bathroom washing area. In this sealing method, a wall that forms the vertical wall of the bathroom is inserted into a groove provided in the floor of the bathroom washing area, and caulking is applied to the gap between the groove and the wall through a caulking material supply nozzle. is injected. When this caulking material hardens, a seal is formed between the floor and the wall, ensuring watertightness.

However, when sealing with caulking material or the like applied at the assembly site, complete quality control is difficult and watertightness cannot be ensured. For example, when sealing with caulking material at an assembly site, sufficient watertightness may not be ensured due to forgetting to apply the caulking material, insufficient amount of caulking material, or lack of skill on the part of the builder. In addition, when assembling a unit room for plumbing equipment, a high level of skill is required from the installer who installs caulking, etc. to ensure reliable watertightness, and there is a shortage of installers with sufficient skills. There is also the problem.

On the other hand, it is conceivable to use packing to ensure watertightness at the joints of building materials that make up the unit room for plumbing equipment. By manufacturing packing in advance at a factory, watertightness can be achieved by simply inserting it between gaps between building materials at the assembly site, and there is little dependence on the skill of the builder.

However, in order to obtain watertightness with the packing, it is necessary to ensure that the packing has sufficient crushing margin in order to press the packing against the building materials to be joined with sufficient force. However, since there are relatively large dimensional and shape errors in buildings in which unit rooms for plumbing equipment are constructed, the gaps between the building materials that make up unit rooms generally vary widely. It is difficult to fill gaps with such large variations while also ensuring sufficient crushing allowance for the packing. For this reason, the current situation is that packing cannot be used as is for sealing parts of unit rooms for plumbing equipment that require high watertightness.

Furthermore, in order to ensure watertightness of the joints of building materials that make up the unit room for plumbing equipment, it is conceivable to use an adhesive such as butyl rubber. When sealing with a sticky material such as butyl rubber, there is no need to secure a large crushing margin like packing to ensure watertightness, and it is possible to easily fill gaps and ensure watertightness. can. For example, it is conceivable to attach butyl rubber tape to the joints of building materials, then peel off the release paper of the butyl rubber tape at the assembly site of the unit room for plumbing equipment, and adhere the building materials to each other with butyl rubber.

However, when assembling building materials at an assembly site, positioning is rarely completed in one go; it is common to temporarily assemble the building materials, adjust their positions, and then finally join them together. However, when building materials are adhered to each other using butyl rubber, it is difficult to separate the members once they have been adhered to each other, and it is not possible to adjust the positions after temporary assembly. Furthermore, if a member that has been adhered once is forcibly removed, the butyl rubber adhesive layer will be destroyed, and there is a risk that sufficient watertightness will not be ensured when the member is reattached. For this reason, adhesives such as butyl rubber are rarely used for sealing building materials that make up unit rooms for plumbing equipment.

Therefore, an object of the present invention is to provide a unit room for plumbing equipment that can ensure reliable watertightness without requiring any special skills from the constructor.

In order to solve the above-mentioned problems, the present invention provides a unit room for plumbing equipment assembled by watertightly joining a plurality of building materials to each other, the first unit room being provided with a joint part to be joined to other building materials. and a watertight adhesive layer formed by continuously applying a heated and liquefied adhesive in a line to the joint of the first building material, and a watertight adhesive layer that is watertight and reusable. a second building material, comprising a joint portion that is adhesively adhered, and is joined to the first building material via the watertight adhesive layer after the temperature of the watertight adhesive layer has decreased to room temperature; A first adhesive area to which the watertight adhesive layer is adhered in advance is provided at the joint of the first building material, and the first building material and the second building material are bonded together through the watertight adhesive layer. Once adhered, the watertight adhesive layer deforms from the first adhesive area to an outwardly adjacent second adhesive area, and then de-adheses the first building material and the second building material. When this occurs, the entire watertight adhesive layer is not broken, but is deformed toward a state in which it is previously adhered to the first adhesive area, and remains on the side of the first building material. It is said that
In the present invention configured as described above, a watertight adhesive layer is formed in advance by continuously applying a heated and liquefied adhesive in a linear manner to the joint portion of the first building material. . Then, after the temperature of the watertight adhesive layer formed at the joint of the first building material falls to room temperature, the joint of the second building material is connected to the first building material through this watertight adhesive layer. Joined.
In addition, when the first building material and the second building material are joined in this way, the second building material A load such as its own load (self-weight) or a pressing force from the second building material to the joint of the first building material acts. As a result, once the first building material and the second building material are adhered via the watertight adhesive layer, the watertight adhesive layer deforms from the first adhesive area to the second adhesive area adjacent to the outside thereof.
Thereafter, when the adhesive between the first building material and the second building material is removed, the entire watertight adhesive layer is deformed from the second adhesive area to the state where it is pre-adhered to the first adhesive area without being broken. By doing so, it remains on the side of the first building material and becomes ready for readhesion.
That is, when assembling the first building material and the second building material, after the first building material and the second building material are once adhered via the watertight adhesive layer, in order to correct the position of the second building material. When the adhesive between the first building material and the second building material is removed, the part of the watertight adhesive layer that has been deformed into the second adhesive area at the joint of the first building material is the same as before adhesion with the second building material. Since the first building material is deformed toward the first adhesive area of the joint, the entire watertight adhesive layer remains on the first building material side without being broken, and becomes ready for re-adhesion. .
Therefore, when reassembling the first building material and the second building material, the watertight adhesive layer may be reapplied to the first building material or the second building material, or the watertight adhesive layer may not be applied from the factory. Since there is no need to newly procure the first building material and the second building material, work efficiency can be improved.
In addition, by performing a simple task of reassembling the removed second building material in the correct position relative to the first building material, it is possible to remove the adhesive that has been previously attached to the first adhesive area of the joint of the first building material. Since watertightness between the first building material and the second building material can be ensured while reusing the entire watertight adhesive layer, ease of assembly can be improved.
As a result, it is possible to provide a unit room for plumbing equipment that can ensure reliable watertightness without requiring special skills from the builder.

In the present invention, preferably, the first building material is a substantially rectangular flooring material constituting the floor surface of the unit room for plumbing equipment, and the second building material is preferably It is a wall material that is joined to a joint provided in the side direction of the floor material, and the joint part on the floor surface of the above-mentioned flooring material has a wall material that is continuously formed along the side direction and connects the lower end of the above-mentioned wall material. A wall-mounted recess is provided to enable the insertion, and the wall-mounted recess of the flooring material includes an inner bottom surface formed at a position recessed below the floor surface and extending in the longitudinal direction of the wall-mounted recess; Inner surfaces extending upward from the inner bottom surface are respectively formed, and the watertight adhesive layer is adhered in advance to the first adhesive region on the inner bottom surface or inner surface of the wall-mounted recess of the flooring material, and Once the flooring material and the wall material are adhered via the watertight adhesive layer, the watertight adhesive layer extends from the first adhesive area to the second adhesive area adjacent to the outside thereof within the wall mounting recess of the flooring material. When the adhesion between the floor material and the wall material is peeled off, the entire watertight adhesive layer deforms to the state where it is previously adhered to the first adhesive area without being broken. and remains on the flooring side.
In the present invention configured as described above, by continuously applying a heated and liquefied adhesive in a linear manner to the inner bottom surface or inner surface of the wall-mounted recess at the joint of the flooring material, A watertight adhesive layer is preformed.
After the temperature of the watertight adhesive layer formed on the inner bottom or inner surface of the wall-mounted recess at the joint of the flooring material has decreased to room temperature, the watertight adhesive layer is applied to the joint of the wall material. It is then joined to the flooring material.
In addition, when the flooring material and the wall material are joined in this way, the watertight adhesive layer that has been formed in advance in a continuous linear shape on the inner bottom surface or inner surface of the wall-mounted recess at the joint of the flooring material, Loads such as the load (self-weight) of the wall material itself or the force exerted from the wall material to the joint of the floor material act. For this reason, once the flooring and wall materials are adhered via the watertight adhesive layer, the watertight adhesive layer extends from the first adhesive area on the inner bottom surface or inner surface of the wall mounting recess at the joint of the flooring materials to the outside thereof. It deforms to the adjacent second adhesive area.
Thereafter, when the adhesive between the flooring material and the wall material is peeled off, the entire watertight adhesive layer is not broken, but extends from the second adhesive area on the inner bottom surface or inner surface of the wall-mounted recess at the joint of the flooring material to the first adhesive layer. By deforming toward the state where it has been previously adhered to the adhesive area, it remains on the flooring side and becomes ready for re-adhesion.
In other words, when assembling the flooring and walling materials, the flooring and walling materials are once attached through a watertight adhesive layer, and then the adhesive between the flooring and walling materials is removed in order to correct the position of the walling material. In some cases, the part of the watertight adhesive layer that has been transformed into the second adhesive area on the inner bottom or inner surface of the wall-mounted recess at the joint of the flooring material may become the second adhesive region of the joint of the flooring material before adhesion to the wall material. Since it deforms toward the first adhesive area on the inner bottom surface or inner surface of the wall-mounted recess, the entire watertight adhesive layer remains on the flooring side without being broken, and becomes ready for re-adhesion.
Therefore, when reassembling flooring and wall materials, it is necessary to reapply the watertight adhesive layer to the flooring or wall materials, or to replace the flooring or wall materials that have been coated with a watertight adhesive layer from the factory. Since there is no need to procure it separately, work efficiency can be improved.
In addition, by simply reassembling the removed wall material in the correct position relative to the flooring material, the entire watertight adhesive layer previously adhered to the first adhesive area of the joint of the flooring material can be reattached. Since it is possible to reliably ensure watertightness between the flooring material and the wall material while using the product, ease of assembly can be improved.
As a result, the flooring and wall materials of the plumbing equipment unit room can be easily assembled.

In the present invention, preferably, the first building material is a substantially rectangular flooring material constituting the floor surface of the unit room for plumbing equipment, and the second building material is preferably It is a wall material that is joined to a joint provided in the side direction of the floor material, and the joint part on the floor surface of the above-mentioned flooring material has a wall material that is continuously formed along the side direction and connects the lower end of the above-mentioned wall material. A wall-mounted recess is provided to enable insertion, and a support member that supports the wall material via the watertight adhesive layer is watertightly provided in the wall-mounted recess of the flooring material. is provided with a support recess that is continuously formed along the side direction of the flooring material and into which the lower end of the wall material can be inserted; An inner bottom surface extending in the longitudinal direction of the support recess and an inner surface extending upward from the inner bottom surface are formed at opposite positions, and the watertight adhesive layer is formed on the inner bottom surface or the inner surface of the support recess. The adhesive is preliminarily attached to the first adhesive area, and once the flooring material and the wall material are adhered via the watertight adhesive layer, the adhesive is attached to the outside of the first adhesive area within the support recess. When the adhesive layer is deformed to the second adhesive area and then the adhesive between the flooring material and the wall material is peeled off, the entire watertight adhesive layer is not broken and returns to the state where it is previously adhered to the first adhesive area. It is configured so that it deforms and remains on the flooring side.
In the present invention configured as described above, an adhesive liquefied by heating is applied to the inner bottom surface or inner surface of the support recess in the support member provided watertightly within the wall-mounted recess at the joint of the flooring material. A watertight adhesive layer is preformed by applying the agent in a continuous line.
After the temperature of the watertight adhesive layer formed on the inner bottom surface or inner surface of the support recess in the support member in the wall-mounted recess at the joint of the flooring material has decreased to room temperature, , and is bonded to the flooring material via this watertight adhesive layer.
In addition, when the flooring material and the wall material are joined in this way, the support member in the wall mounting recess at the joint of the flooring material is formed in a continuous linear shape with respect to the inner bottom surface or inner surface of the support recess. A load such as the load (self-weight) of the wall material itself or the force of pressing the wall material against the joint of the floor material acts on the watertight adhesive layer. For this reason, once the flooring and wall materials are adhered via the watertight adhesive layer, the watertight adhesive layer is attached to the inner bottom surface or the first inner surface of the support recess in the support member in the wall-mounted recess at the joint of the flooring material. from the adhesive area to the second adhesive area adjacent to the outside thereof.
Thereafter, when the adhesive between the flooring material and the wall material is removed, the entire watertight adhesive layer is not broken and the second layer on the inner bottom surface or inner surface of the support recess in the support member in the wall-mounted recess at the joint of the flooring material is removed. By deforming from the adhesive area toward the state where it has been previously adhered to the first adhesive area, it remains on the flooring side and becomes ready for re-adhesion.
In other words, when assembling the flooring and walling materials, the flooring and walling materials are once attached through a watertight adhesive layer, and then the adhesive between the flooring and walling materials is removed in order to correct the position of the walling material. Sometimes, the part of the watertight adhesive layer that has been deformed into the second adhesive area on the inner bottom surface or inner surface of the support recess in the support member in the wall-mounted recess at the joint of the flooring material is in a state before adhesion with the wall material. Because the support member in the wall-mounted recess at the joint of the flooring material deforms toward the first adhesive area on the inner bottom or inner surface of the support recess, the entire watertight adhesive layer does not break and the flooring material It remains on the side and becomes ready for re-adhesion.
Therefore, when reassembling flooring and wall materials, it is necessary to reapply the watertight adhesive layer to the flooring or wall materials, or to replace the flooring or wall materials that have been coated with a watertight adhesive layer from the factory. Since there is no need to procure it separately, work efficiency can be improved.
In addition, by simply reassembling the removed wall material in the correct position relative to the flooring material, the entire watertight adhesive layer previously adhered to the first adhesive area of the joint of the flooring material can be reattached. Since it is possible to reliably ensure watertightness between the flooring material and the wall material while using the product, ease of assembly can be improved.
As a result, the flooring and wall materials of the plumbing equipment unit room can be easily assembled.

According to the unit room for plumbing equipment of the present invention, reliable watertightness can be ensured without requiring special skills by the constructor.

Next, a method for manufacturing a unit room for plumbing equipment according to the first embodiment of the present invention will be described with reference to FIGS. 8 to 10.
FIG. 8 is a flowchart showing a method for manufacturing a unit room for plumbing equipment according to this embodiment. FIG. 9 is an explanatory diagram schematically showing each step of the method for manufacturing a unit room for plumbing equipment according to the present embodiment. FIG. 10 is an explanatory diagram schematically showing the steps for forming and protecting an adhesive layer in the method of manufacturing a unit room for plumbing equipment according to the present embodiment.

In the method of manufacturing a unit room for plumbing equipment according to an embodiment of the present invention, first, building materials such as the flooring material 2, wall material 4, frame 6, ceiling material 8, etc. that constitute the unit room described above, and the bathtub 10 is manufactured at a manufacturing factory. Next, the manufactured building materials, etc. are transported to a construction site for a house or the like, and the building materials, etc. are assembled at the construction site to complete a unit room for plumbing equipment.

In step S1 of the flowchart shown in FIG. 8, building materials such as the flooring material 2, wall material 4, frame 6, ceiling material 8, etc. are assembled as a building material preparation step. For example, as shown in column (A) of FIG. 9, the flooring 2 is assembled and prepared by attaching the floor surface 14a and the like to the flooring main body 14.

Next, in step S2, as a watertight adhesive layer forming step, a heated and liquefied adhesive is applied in a continuous line to the joint part of the building material to be joined to another building material, and the joint part of the building material is coated in a continuous line. A watertight adhesive layer is formed. In this embodiment, as shown in column (B) of FIG. 9, the adhesive is applied by a robot arm using a nozzle that continuously extrudes the liquefied adhesive at the manufacturing factory along the joints of the building materials. It is executed by moving. That is, by applying liquefied adhesive in a continuous line to the grooves 18 of the flooring material 2 manufactured as shown in column (A) of FIG. 10, the adhesive shown in column (B) of FIG. The first adhesive layer 16, which is a watertight adhesive layer, is thus formed. In addition, in this embodiment, as shown in column (B) of FIG. 10, the adhesive is continuously applied in a linear manner also at the corners of the building material such as the flooring material 2. That is, since the first adhesive layer 16 is formed by continuously applying adhesive along a plurality of sides sandwiching the corners of the flooring material, a continuous watertight adhesive layer is formed without any seams even at the corners. is formed as.

In this embodiment, for example, regarding the joint between the flooring material 2 and the wall material 4, a heated and liquefied adhesive is applied to the groove portion 18, which is the joint, of the flooring material 2, which is the first building material. Then, the first adhesive layer 16 is formed (see FIG. 3). Note that at this time, the first adhesive layer 16 is applied so as not to protrude from the groove 18 . Furthermore, when assembling the plumbing equipment unit room 1, the lower end of the joint part of the wall material 4, which is the second building material, touches the first adhesive layer 16 provided in the groove 18 of the floor material 2. The floor material 2 and wall material 4 are bonded together.

Similarly, a heated and liquefied adhesive is applied in a continuous line to the inside of the second joiner 20b of the frame 6, thereby forming a watertight adhesive layer on the second joiner 20b, which is the joining part. A second adhesive layer 22 is formed. In addition, in joining the frame 6 and the wall material 4, the frame 6 on which the second adhesive layer 22 is formed acts as the first building material, and the wall material 4 joined thereto acts as the second building material. . Similarly, the second adhesive layer 22 is formed on the frame 36 as well. Furthermore, a heated and liquefied adhesive is applied in a continuous line to the inside of the second receiving part 28b of the ceiling material 8, thereby forming a watertight adhesive layer on the second receiving part 28b, which is the joint part. A third adhesive layer 26 is formed. In joining the ceiling material 8 and the wall material 4, the ceiling material 8 on which the third adhesive layer 26 is formed acts as the first building material, and the wall material 4 joined thereto acts as the second building material. .

Further, in step S3, as a curing step, each adhesive layer formed in the watertight adhesive layer forming step of step S2 is lowered in temperature to room temperature, for example, to about 20 to 25°C. Through this curing step, each adhesive layer exhibits elasticity and shape recovery properties, and the form of the adhesive layer is stabilized. In addition, in this embodiment, the time required for the temperature of the liquefied adhesive applied to building materials such as the flooring material 2 to decrease to room temperature is relatively short. For this reason, as shown in column (C) of Fig. 9, building materials such as flooring material 2, which have been coated with adhesive, are left with no adhesive during the storage period before being sent to the next process in the manufacturing factory or during the transportation period. The temperature of the agent layer decreases to room temperature. Therefore, in this embodiment, the storage period and transportation period of the building material after the watertight adhesive layer forming step function as a curing step.

Next, the adhesive layer, which is a watertight adhesive layer formed by the watertight adhesive layer forming step and the curing step, will be explained.
The first adhesive layer 16 formed by the watertight adhesive layer forming process and the curing process is adhered to the flooring material 2 coated with heated adhesive, and when it comes into contact with the wall material 4 during assembly, It also adheres to these building materials. Similarly, the second adhesive layer 22 and the third adhesive layer 26 are also adhered to the frames 6, 36 and the ceiling material 8, respectively, and are also adhered to the wall material 4 during assembly.

Here, "adhesion" refers to a phenomenon commonly observed in high-viscosity liquids, which causes no change in state and sticks together just by applying a slight pressure for a short period of time, closing or filling gaps (exhibiting sealing properties). ) is a phenomenon. Adhesives are also called pressure sensitive adhesives. Note that adhesive is a material that never completely dries even after a period of time and always has adhesive properties. This is completely different from so-called adhesives, which lose their adhesive properties over time (their adhesion approaches zero). For example, silicone caulks used in common bathroom seals are classified as adhesives because they lose their adhesive properties when dry (hardened).

Furthermore, the first, second, and third adhesive layers formed through the watertight adhesive layer forming step and the curing step have elasticity and shape restorability. That is, having elasticity and shape recovery property means that the compression set after compressing and deforming each adhesive layer and removing the load is, for example, 20% or less (JIS K 6254:2016). The compression set of each pressure-sensitive adhesive layer may be the same or different.

In addition, in this specification, "compression permanent strain" is a value calculated|required by the following method, for example. A cylindrical sample with a diameter of 27 mm and a thickness of 20 mm is prepared, and the sample is compressed to a thickness of 50% (10 mm) and left at a high temperature (approximately 80° C.) for a predetermined time. Thereafter, the compression is released and the dimension of the sample in the thickness direction is measured. The rate of change in the dimension of the sample in the thickness direction can be determined as the compression set.

Furthermore, in this embodiment, building materials such as the flooring material 2, wall material 4, frame 6, ceiling material 8, etc. are adhered watertightly and re-adhesively by the first, second, and third adhesive layers. . Here, "re-adhesive" means, for example, that after the flooring material 2 and the wall material 4 provided with the first adhesive layer 16 are once bonded via the first adhesive layer 16, When the wall material 4 is peeled off, the first adhesive layer 16 remains on the floor material 2 (the building material on which the adhesive was first applied) without being destroyed, and the first adhesive layer 16 remaining on the floor material 2 This means that the adhesive layer 16 still retains its adhesive properties. Therefore, even if the wall material 4 is peeled off from the floor material 2 in order to adjust the position of the wall material 4 after the floor material 2 and the wall material 4 are bonded together using the first adhesive layer 16, the wall material 4 is reattached. It can be adhered to the floor material 2 and bonded.

In this way, in order to bond the flooring material 2 and the wall material 4 "re-adhesively" using the first adhesive layer 16, the adhesive force between the first adhesive layer 16 and the flooring material 2 is It needs to be stronger than the adhesive force between the adhesive layer 16 and the wall material 4. Furthermore, the tensile strength of the first adhesive layer 16 itself needs to be stronger than these adhesive forces. By satisfying these conditions, when the floor material 2 and wall material 4 bonded by the first adhesive layer 16 are peeled off, the interface between the adhered first adhesive layer 16 and wall material 4 will peel off. However, the first adhesive layer 16 remains on the flooring material 2 without being destroyed, and re-adhesion becomes possible. On the other hand, when building materials that have been bonded together using a silicone caulking agent used to seal general bathrooms are peeled off, the layer of silicone caulking is destroyed instead of separating between the building material and the caulking agent. It ends up.

In this embodiment, a heated and liquefied adhesive is applied to the floor material 2 in the watertight adhesive layer forming step. Therefore, the adhesive force between the first adhesive layer 16 and the flooring material 2 is lower than the adhesive force between the first adhesive layer 16 and the wall material 4, which are adhered after the temperature has decreased to room temperature through the curing process. It also becomes stronger.

Similarly, when the flooring material 2 and the frame 6 are bonded together via the second adhesive layer 22, when they are peeled off, the first adhesive layer 16 remains on the flooring material 2 side and is re-adhesive. It becomes possible. Further, the second adhesive layer 22 is formed by applying a liquefied adhesive to the frame 6. Therefore, when the wall material 4 and the frame 6 are bonded via the second adhesive layer 22, when they are peeled off, the second adhesive layer 22 remains on the frame 6 side and can be re-adhered. becomes.
Furthermore, the third adhesive layer 26 is formed by applying a liquefied adhesive to the ceiling material 8. Therefore, when the wall material 4 and the ceiling material 8 are bonded together via the third adhesive layer 26, when they are peeled off, the third adhesive layer 26 remains on the ceiling material 8 side and can be reused. It becomes sticky.
Furthermore, even when the frame 6 and the ceiling material 8 are bonded via the second adhesive layer 22, when they are peeled off, the third adhesive layer 26 remains on the ceiling material 8 side and can be re-adhered. becomes.

In this embodiment, the first adhesive layer 16, the second adhesive layer 22, and the third adhesive layer 26 are made of, for example, an elastic hot melt made by Aica Kogyo Co., Ltd. By using elastic hot melt as an adhesive, the elastic hot melt is heated to liquefy and applied at the manufacturing factory, then cooled to form the shape, and then the installer glues each component together on site. Can be connected by a layer of adhesive. That is, it becomes possible to connect building materials at the site with the adhesive layer while suppressing the adhesive from changing its shape during transportation to the site or to the site. This makes it possible to easily ensure watertightness on site and improve workability.

Further, the first adhesive layer 16, the second adhesive layer 22, and the third adhesive layer 26 can also be made of a gel (gel-like substance) having adhesiveness and elasticity. The compositions of the first adhesive layer 16, the second adhesive layer 22, and the third adhesive layer 26 may be the same or different.

In this embodiment, a hot melt composition containing a hydrogenated paraffinic process oil, a high molecular weight styrenic block copolymer, a polyphenylene ether resin, or a modified polyphenylene ether resin is added with a tackifying resin and an antioxidant. Used as an adhesive. The first, second, and third adhesive layers are formed by applying the liquefied adhesive to a building material in a continuous line by heating.

As the tackifier resin, terpene resin, terpene phenol resin, rosin and hydrogenated rosin resin, petroleum resin, hydrogenated petroleum resin, etc. can be used. In addition, antioxidants include copper-based antioxidants, copper salt-based antioxidants, halogenated copper-based antioxidants, phosphorus-based antioxidants, phenolic-based antioxidants, hindered amine-based antioxidants, and Those selected from dirt phenol type antioxidants, sulfur type antioxidants, lactone type antioxidants, aromatic amines, metal deactivators consisting of chelating agents, etc. can be used. Furthermore, the tackifier resin is preferably added in an amount of about 2.5 to 30 parts by weight per 100 parts by weight of the hot melt composition, and by adjusting the content of the tackifier resin, the adhesive strength of each adhesive layer can be adjusted. can do.

Next, in step S4 of FIG. 8, as a watertight adhesive layer protection step, a curing tape 30, which is a cover that covers the adhesive layer formed in the watertight adhesive layer forming step of step S3, is attached to the building material. That is, as shown in column (C) of FIG. 10, the curing tape 30 is pasted so as to cover the groove portion 18 of the floor material 2 coated with the liquefied adhesive. This can prevent dust and the like from adhering to the surface of the first adhesive layer 16 formed in the groove 18 and reducing the adhesive strength of the first adhesive layer 16. Moreover, by pasting the curing tape 30, it is possible to prevent the first adhesive layer 16 from being damaged by accidentally touching the first adhesive layer 16 during transportation or the like. Similarly, a curing tape 30 is attached to the frame 6 so as to cover the second adhesive layer 22 formed on the frame 6, and a curing tape 30 is attached to the ceiling material 8 so as to cover the third adhesive layer 26 formed on the ceiling material 8. A curing tape 30 is pasted on.

In this embodiment, the watertight adhesive layer protection process is performed after the curing process in step S3, but the watertight adhesive layer protection process is performed before the curing process (i.e., when the temperature of the adhesive drops to room temperature). (before curing) or in parallel with the curing step. Further, the watertight adhesive layer protection step may be performed at any time after the watertight adhesive layer forming step and before the assembly step of step S5. Alternatively, the watertight adhesive layer protection step can also be omitted. Furthermore, in this embodiment, the curing tape 30 is used as a cover for covering the adhesive layer, but any member capable of covering the adhesive layer can be used as the cover.

Next, in step S5, as an assembly process, the building materials with the adhesive layer formed at the joints and the joints of other building materials are adhered watertightly and re-adhesively to join the building materials together. Thus, the plumbing equipment unit room 1 is assembled. That is, first, the floor material 2 and the frame 6 are bonded together by adhesion via the second adhesive layer 22. Note that before joining the flooring material 2 and the frame 6, as shown in column (D) of FIG. Leave 16 exposed. Next, the frame 6 and the wall material 4 are bonded together via the second adhesive layer 22, and the floor material 2 and the wall material 4 are bonded together via the first adhesive layer 16. Finally, the ceiling material 8 and the wall material 4, and the ceiling material 8 and the frame 6 are bonded together through the second adhesive layer 22, thereby completing the production of the unit room 1 for plumbing equipment.

Next, the assembly process will be described in detail with reference to FIGS. 11 to 23.
11 and 12 are perspective views for explaining the assembly procedure of the unit room 1 for plumbing equipment. FIG. 13 is an enlarged cross-sectional view showing the connecting portion between the flooring material 2 and the frame 6 during assembly of the unit room 1 for plumbing equipment.

FIG. 18 is a cross-sectional view schematically showing the behavior of the first adhesive layer 16 when the wall material 4 that has been once adhered to the floor material 2 is re-adhered. FIGS. 19 and 20 are enlarged cross-sectional views schematically showing the connecting portion between the wall material 4 and the frame 6 of the plumbing equipment unit room 1. FIG. 21 is a perspective view for explaining the assembly procedure of the unit room 1 for plumbing equipment. FIG. 22 is an enlarged cross-sectional view schematically showing a connecting portion between the frame 6 and the ceiling material 8 of the unit room 1 for plumbing equipment. FIG. 23 is an enlarged cross-sectional view schematically showing the connecting portion between the wall material 4 and the ceiling material 8 of the plumbing equipment unit room 1.

First, as shown in FIG. 11, the flooring material 2 is installed on a bathroom installation surface via support legs 12 having a height-adjustable structure. The flooring material 2 has a flooring material body 14 and a first adhesive layer 16 provided on the outer peripheral edge of the flooring material body 14. Note that the curing tape 30 protecting the first adhesive layer 16 of the flooring material 2 is removed when the first adhesive layer 16 and other building materials are adhered. Further, the bathtub 10 is installed on the bathroom installation surface via the support legs 12. In this example, the first adhesive layer 16 is also provided on the outer peripheral edge 10a of the bathtub 10. Furthermore, a bath apron 10b is attached to the boundary between the bathtub 10 and the flooring 2.

Next, as shown in FIG. 12, frames 6 and 36 are attached to the peripheral edge of the flooring 2 and the outer peripheral edge 10a of the bathtub 10. Each frame 6, 36 has a frame body 20 and a second adhesive layer 22 provided on the side surface of the frame body 20. When the frames 6 and 36 are attached, the lower ends of the second adhesive layers 22 provided on the frames 6 and 36, respectively, and the first adhesive layer 16 provided on the flooring 2 are adhered.

As shown in FIGS. 13 and 14, first, when the frame 6 is placed at a predetermined position on the flooring 2, the lower end of the second adhesive layer 22 provided on the frame 6 The second adhesive layer 22 and the first adhesive layer 16 are adhered to each other by contacting the first adhesive layer 16 . Similarly, when the frame 36 is placed at the corner of the flooring 2, the lower end of the second adhesive layer 22 provided on the frame 36 comes into contact with the first adhesive layer 16 of the flooring 2, and the second adhesive The adhesive layer 22 and the first adhesive layer 16 are adhered. These first adhesive layer 16 and second adhesive layer 22 close the gap between the flooring main body 14 and the frame main body 20, making it watertight. That is, at the intersection of the first adhesive layer 16 provided on the flooring material 2 and the second adhesive layer 22 provided on the frames 6 and 36, these adhesive layers self-fuse with each other. Watertightness between the two is automatically ensured. On the other hand, if packing is used instead of the first and second adhesive layers, watertightness cannot be ensured at the intersections of the packings, so silicone caulking will need to be applied. . In this way, in the plumbing equipment unit room 1 of this embodiment, it is possible to omit application of silicone caulking or the like at the assembly site.

Next, as shown in FIG. 15, the wall material 4 is attached to the floor material 2, the bathtub 10, and the frame 6. At this time, the first adhesive layer 16 provided on the floor material 2 is adhered to the lower end of the wall material 4, and the second adhesive layer 22 provided on the frame 6 is adhered to the side edge of the wall material 4. let At this time, as shown in FIG. 16, the lower end of the wall material 4 is fitted into the groove 18 provided on the outer peripheral edge of the floor material body 14. Thereby, the first adhesive layer 16 provided in the groove portion 18 adheres to the lower end portion of the wall material 4.

Further, as shown in FIG. 16, the wall material 4 is connected to the frame 6 by fitting the side end portion of the wall material 4 into the first joiner 20a of the frame 6. Similarly, the wall material 4 is connected to the frame 36 by fitting the side end portion of the wall material 4 into the first joiner 36a (not shown in FIG. 16) of the frame 36. Thereby, the second adhesive layer 22 provided on the second joiner 20b of the frame 6 and the second joiner 36b of the frame 36 adheres to the side edge portion of the wall material 4.

That is, as shown in FIG. 17A, when the wall material 4 is disposed on the inner bottom surface 18c of the wall-mounted recess 18 of the floor material 2, the first adhesive layer 16 provided on the floor material 2 is placed under the wall material 4. It contacts the end surface 4a. As a result, the upper surface of the first adhesive layer 16 is elastically deformed along the lower end surface 4a of the wall material 4 due to the load of the wall material 4, and the first adhesive layer 16 and the wall material 4 are tightly adhered. . This first adhesive layer 16 closes the gap between the floor material main body 14 and the wall material 4, making it watertight.
Furthermore, as shown in FIGS. 17A and 17B, once the floor material 2 and the wall material 4 are adhered via the first adhesive layer 16, the first adhesive layer 16 is It is compressed by the lower end surface 4a of the wall material 4.
As a result, the first adhesive layer 16 is moved from the first adhesive area A1 in a pre-adhesive state (initial state C1 before compression deformation) on the inner bottom surface 18c of the wall-mounted recess 18 of the floor material 2 to the outside thereof. The second adhesive area A2 adjacent to the second adhesive area A2 is in a deformed state (compressively deformed state C2).
Thereafter, as shown in FIG. 17B, when the adhesive between the floor material 2 and the wall material 4 is removed, the entire first adhesive layer 16 is not broken, and the second adhesive area A2 changes from the deformed state C2. After passing through an intermediate deformation state (state C3 during restoration), it deforms toward the initial state C1 before compressive deformation of the first adhesive area A1, thereby remaining on the flooring material 2 side and becoming ready for re-adhesion. .

That is, after the wall material 4 is adhered to the floor material 2, in order to correct the position of the wall material 4, the first adhesive layer 16 and the wall material 4 that have been once adhered can be peeled off and re-adhered. .
FIG. 18 is a diagram schematically showing the behavior of the first adhesive layer 16 at this time. To explain the behavior (series of deformation processes) of the first adhesive layer 16 in more detail using FIG. 18, first, as shown in column (A) of FIG. The first adhesive layer 16 is adhered in advance to the first adhesive area A1 of the inner bottom surface 18c of the recess 18, and when the wall material 4 is placed on the groove 18 of the floor material 2, the area shown in column (B) is As shown, the first adhesive layer 16 is elastically deformed to the second adhesive area A2, and the lower end surface of the wall material 4 and the first adhesive layer 16 are adhered without any gap. At this time, since the thickness of the first adhesive layer 16 changes due to elastic deformation, even if the floor material 2 or wall material 4 is distorted, the gap between them can be filled.
Next, when the wall material 4 is pulled up from the floor material 2 in order to correct the position of the wall material 4, the first adhesive layer 16 remains stuck to the wall material 4, as shown in column (C) of FIG. Stretched out. In this way, since the flooring material 2 and the wall material 4 are adhesively bonded via the first adhesive layer 16, even if the flooring material 2 is bent due to a load, the flooring material 2 and the wall material 4 There are no gaps between them, and watertightness is maintained. On the other hand, if packing had been used instead of the adhesive layer, if the floor material flexes and there is no room for the packing to collapse, a gap will form between the packing and the wall material, impairing watertightness. There is a risk that it may occur.

Further, when the wall material 4 is pulled up further, the interface between the wall material 4 and the first adhesive layer 16 peels off, and the first adhesive layer 16 changes its shape. Due to the restorability, the second adhesive area A2 is almost restored to the form before adhesion to the wall material 4 (first adhesive area A1). As described above, the adhesive force between the first adhesive layer 16 and the floor material 2 is stronger than the adhesive force between the first adhesive layer 16 and the wall material 4. Therefore, when the wall material 4 is pulled up, the interface between the first adhesive layer 16 and the wall material 4 is separated, and the first adhesive layer 16 remains on the floor material 2 side.
Furthermore, the breaking strength of the first adhesive layer 16 itself is greater than the adhesive force between the first adhesive layer 16 and the wall material 4 and the adhesive force between the first adhesive layer 16 and the floor material 2. Therefore, as shown in column (C) of FIG. 18, when the first adhesive layer 16 is stretched, the first adhesive layer 16 itself is not broken. Moreover, since the first adhesive layer 16 still maintains its adhesiveness even after the wall material 4 is peeled off, the wall material 4 can be re-attached.

As described above, in this embodiment, the first adhesive layer 16 for adhering the floor material 2 and wall material 4 to each other is formed on the floor material 2 side, and the first adhesive layer is formed on the wall material side. The workability of assembly is improved compared to the previous case. That is, if the first adhesive layer is formed at the lower end of the wall material, it is easy to accidentally attach the first adhesive layer of the wall material to an unintended position on the floor material during assembly, and the wall The material becomes difficult to handle.
Moreover, if the first adhesive layer remains on the wall material side when the wall material is peeled off from the floor material after being adhered once, it becomes difficult to handle the wall material. Furthermore, when one of the plurality of wall materials 4 adhered to the floor material 2 is peeled off from the floor material 2, the first adhesive layer 16 is attached to the wall material 4 adjacent to the wall material 4 to be peeled off. is suppressed by. Therefore, the risk of the first adhesive layer 16 peeling off from the flooring 2 can be further reduced.

Further, when the wall material 4 is placed on the floor material 2, the side edges of the wall material 4 are adhered and joined to the frame 6 and the frame 36, respectively, via the second adhesive layer 22. That is, the two wall materials 4 arranged side by side on one side of the floor material 2 are connected via the frame 6 provided between them. Furthermore, two wall materials 4 placed adjacent to each other with a corner of the floor material 2 in between are connected via a frame 36 provided between them.

As described above, in this embodiment, the second adhesive layer 22 for adhering the frames 6, 36 and the wall material 4 is formed on the sides of the frames 6, 36, and the second adhesive layer 22 is formed on the sides of the frames 6, 36. The workability of assembly is improved compared to the case where it is formed. That is, the frame is an elongated columnar member and is easier to handle than the wall material 4, which is a large panel-like member. Therefore, even if the second adhesive layer 22 is formed on the frames 6, 36, the workability will not be significantly deteriorated. On the other hand, if the second adhesive layer is formed on the side of the wall material, handling of the wall material becomes difficult.

FIG. 19 is a sectional view showing a state in which two wall materials 4 arranged side by side are connected via a frame 6. As shown in FIG. 19, the wall material 4 includes a base material 32 and a steel plate 34 provided inside the plumbing equipment unit room 1 with respect to the base material 32. The base material 32 is made of gypsum board or the like, and a steel plate 34 is attached to the inner surface of the plumbing equipment unit room 1 of the base material 32 for reinforcement. Further, the ends of the steel plate 34 protrude from the base material 32 on both left and right sides, and are provided with folded portions 34a to the back side. The folded portions 34a of the two adjacent wall materials 4 are butted against each other, and these folded portions 34a are received inside the frame 6.

That is, each folded portion 34a of the two wall materials 4 is fitted into the first joiner 20a of the frame 6 so as to spread the first joiner 20a apart. The tip of each fitted folded portion 34a faces the second joiner 20b arranged inside the first joiner 20a, and contacts the second adhesive layer 22 provided inside the second joiner 20b. As a result, the second adhesive layer 22 is elastically deformed, and the tip of each folded portion 34a and the second adhesive layer 22 are adhered without any gaps, and each wall material 4 and the second adhesive layer 22 are made watertight. Joined. That is, even if water intrudes between the two wall materials 4 that are butted together, the water is stopped by the watertight bond between the tip of each folded portion 34a and the second adhesive layer 22, and the water-related equipment Water will not leak to the outside of the unit room 1. The two wall materials 4 attached to the frame 6 are not only adhered to the second adhesive layer 22, but also fixed by fitting each folded portion 34a inside the first joiner 20a. The wall material 4 is prevented from falling off.

FIG. 20 is a sectional view showing a state in which two wall materials 4 placed adjacent to each other across a corner of the plumbing equipment unit room 1 are connected via a frame 36. As described above, the wall material 4 includes a base material 32 and a steel plate 34 attached to the base material 32, and a folded portion 34a is provided at the end of the steel plate 34. The shape of this folded portion 34a is the same as that shown in FIG. 19, in which the wall materials 4 are aligned and joined together. On the other hand, the frame arranged at the corner of the plumbing equipment unit room 1 is a corner frame 36 having a different shape from that shown in FIG.

This corner frame 36 is also composed of a first joiner 36a and a second joiner 20b provided inside the first joiner 36a, and a second adhesive layer that is a watertight adhesive layer is applied inside the second joiner 36b. Layer 22 is adhered. The second joiner 36b is oriented to face the corner of the unit room 1 for plumbing equipment, and the second adhesive layer 22 is provided on the inside thereof so as to face the corner.

The folded portion 34a of each wall material 4 is fitted into the first joiner 36a, and the fitted folded portion 34a contacts and adheres to the second adhesive layer 22, so that each wall material 4 and the second adhesive layer Watertightness is ensured between 22 and 22. Note that in the corner frame 36, the surface of the folded portion 34a that is bent at right angles to the surface of the steel plate 34 comes into contact with the second adhesive layer 22, and there is a gap between this surface and the second adhesive layer 22. Watertightness is ensured.

Next, as shown in FIG. 21, ceiling material 8 is attached on top of each frame 6, 36 and on each wall material 4. The ceiling material 8 includes a ceiling material main body 24 and a third adhesive layer 26 provided on the outer peripheral edge of the ceiling material main body 24. When attaching the ceiling material 8, the upper end of the second adhesive layer 22 provided on the frames 6, 36 is adhered to the third adhesive layer 26 provided on the ceiling material 8, and the third adhesive layer 26 is Adhere it to the upper end of the wall material 4. The gap between the ceiling material body 24 and the frame body 20 is closed and watertight by the second adhesive layer 22 and the third adhesive layer 26. Furthermore, the third adhesive layer 26 closes the gap between the ceiling material main body 24 and the upper end of the wall material 4, making it watertight.

That is, as shown in FIG. 22, when the ceiling material 8 is attached to the frame 6, the upper end of the frame 6 is received in the second receiving part 28b of the connecting member 28 attached to the ceiling material main body 24. It will be done. In this state, the upper end portion of the second adhesive layer 22 provided on the frame 6 adheres to the third adhesive layer 26 provided on the ceiling material 8. The gap between the ceiling material body 24 and the frame body 20 is closed and watertight by the second adhesive layer 22 and the third adhesive layer 26. At this time, at least a portion of the frame body 20 may be in contact with the ceiling material 8.

Further, as shown in FIG. 23, at the joint between the wall material 4 and the ceiling material 8, the third adhesive layer 26 provided on the ceiling material 8 adheres to the upper end portion of the wall material 4. That is, in a state where the ceiling material 8 is attached on the wall material 4, the upper end portion of the wall material 4 is received in the second receiving portion 28b of the connecting member 28 attached to the ceiling material main body 24. The third adhesive layer 26 closes the gap between the ceiling material 8 and the upper end of the wall material 4, making it watertight.
By attaching the ceiling material 8 in this way, the assembly of the plumbing equipment unit room 1 is completed.

According to the plumbing equipment unit room 1 according to the first embodiment of the present invention described above, the adhesive heated and liquefied is applied to the inner bottom surface 18c of the wall-mounted recess 18, which is the joint part of the flooring material 2. The first adhesive layer 16 is formed in advance by continuously applying the adhesive in a linear manner.
Then, for the joint part (lower end surface 4a) of the wall material 4, after the temperature of the first adhesive layer 16 formed on the inner bottom surface 18c of the wall-mounted recess 18 of the floor material 2 has decreased to room temperature, It is bonded to the flooring material 2 via this first adhesive layer 16.
Moreover, when the flooring material 2 and the wall material 4 are joined in this way, the first adhesive layer 16, which has been formed in advance in a continuous linear shape with respect to the inner bottom surface 18c of the wall-mounted recess 18 of the flooring material 2, Then, a load such as the load (self-weight) of the wall material 4 itself or the force of pressing the wall material 4 against the wall mounting recess 18 of the floor material 2 acts. Therefore, once the flooring material 2 and the wall material 4 are attached to each other via the first adhesive layer 16, the first adhesive layer 16 is attached to the first adhesive layer of the inner bottom surface 18c of the wall mounting recess 18 of the flooring material 2. The deformation occurs from the area A1 to the second adhesion area A2 adjacent to the outside thereof.
Thereafter, when the adhesive between the flooring material 2 and the wall material 4 is removed, the entire first adhesive layer 16 is not broken, but extends from the second adhesive area A2 of the inner bottom surface 18c of the wall-mounted recess 18 of the flooring material 2. , deforms toward the state C1 in which it is previously adhered to the first adhesive area A1, thereby remaining on the flooring material 2 side and becoming ready for re-adhesion.
That is, when assembling the flooring material 2 and the wall material 4, after the flooring material 2 and the wall material 4 are once adhered to each other via the first adhesive layer 16, the flooring material 2 is attached to the wall material 4 in order to correct the position of the wall material 4. 2 and the wall material 4, the part of the first adhesive layer 16 that had been transformed into the second adhesive area A2 of the inner bottom surface 18c in the wall-mounted recess 18 of the floor material 2 was removed from the wall material 4. Since the inner bottom surface 18c of the wall-mounted recess 18 of the floor material 2 in the state C1 before adhesion is deformed toward the first adhesive area A1, the entire first adhesive layer 16 is not broken and is attached to the floor. It remains on the material 2 side and becomes ready for re-adhesion.
Therefore, when reassembling the flooring material 2 and wall material 4, the first adhesive layer 16 may be reapplied to the flooring material 2 or the wall material 4, or the first adhesive layer 16 may be removed from the factory. Since there is no need to newly procure coated floor materials 2 and wall materials 4, work efficiency can be improved.
In addition, by performing a simple operation of reassembling the removed wall material 4 to the floor material 2 in the correct position, it is possible to confirm that the wall material 4 has been previously adhered to the first adhesive area A1 of the wall mounting recess 18 of the floor material 2. Since the entire first adhesive layer 16 can be reused and watertightness between the floor material 2 and the wall material 4 can be ensured, ease of assembly can be improved.
Similarly, when reassembling the frame 6 or the ceiling material 8 and the wall material 4, the second adhesive layer 22 or the third adhesive layer 26 may be reapplied to the frame 6 or the ceiling material 8. Since there is no need to newly procure the frame 6 and ceiling material 8 coated with the second adhesive layer 22 and the third adhesive layer 26 from the factory, work efficiency can be improved.
Similarly, by simply reassembling the removed wall material 4 to the frame 6 and ceiling material 8 in the correct position, the joints of the frame 6 and ceiling material 8 (second joiner 20b , while reusing the entire second adhesive layer 22 and third adhesive layer 26 that were previously adhered to the second receiving portion 28b), the watertightness between the frame 6 or the ceiling material 8 and the wall material 4 is improved. Since this can be ensured, assembly efficiency can be improved.
As a result, the flooring material 2, frame 6, ceiling material 8, and wall material 4 of the unit room 1 for plumbing equipment can be easily assembled, and no special skills are required by the installer, ensuring watertightness. It is possible to provide a unit room 1 for plumbing equipment that can ensure the safety of the user.

Next, a unit room 100 for plumbing equipment according to a second embodiment of the present invention will be described with reference to FIGS. 24A to 24E.
FIGS. 24A to 24D are partially enlarged cross-sectional views of the wall-mounted recess 18 of the flooring material 2 of the unit room 100 for plumbing equipment according to the second embodiment of the present invention. In the assembly, the behavior of the first adhesive layer 16 when the wall material 4 that has been once adhered to the floor material 2 is re-adhered is shown schematically.
Furthermore, as a comparative example of the present invention, FIG. 24E shows the behavior of the first adhesive layer when re-adhering the wall material that has been once attached to the flooring material in assembling a unit room for plumbing equipment other than the present invention. show.
Here, in the unit room 100 for plumbing equipment according to the present embodiment shown in FIGS. 24A to 24D, the same parts as those in the unit room 1 for plumbing equipment according to the first embodiment of the present invention described above have the same reference numerals. , and their explanations will be omitted.

As shown in FIGS. 24A to 24D, in the unit room 100 for plumbing equipment according to the present embodiment, in the wall-mounted recess 118 that is the joint of the flooring 102, there is a floor that supports the lower end of the wall 4. A support member 119, which is a joint between the members 102, is watertightly provided along the inside of the wall-mounted recess 118. This support member 119 is a concave member whose cross section is approximately U-shaped, and has an inner bottom surface 119a, and a first inner surface 119b and a second inner surface 119c provided at one end and the other end thereof, respectively. , forming a support recessed portion.
The first adhesive layer 16 is formed by continuously applying a heated and liquefied adhesive in a linear manner to the inner bottom surface 119a of the support member 119 in the wall-mounted recess 118 of the flooring material 102. It is preformed by
The lower end surface 4a, which is the joint part of the wall material 4, is joined to the floor material 102 via the first adhesive layer 16 after the temperature of the first adhesive layer 16 has decreased to room temperature. ing.
In addition, in this embodiment, the first adhesive layer 16 is formed along the inner bottom surface 118a of the support member 119 in the wall-mounted recess 118 of the flooring material 102. The layer 16 may be formed along the first inner surface 119b or the second inner surface 119c of the support member 119 within the wall-mounted recess 118.

First, as shown in FIG. 24A, the first adhesive layer 16 is adhered in advance to the first adhesive area A1 of the inner bottom surface 118a of the support member 119 in the wall-mounted recess 118 of the flooring material 102, and When the material 4 is placed on the wall-mounted recess 118 of the floor material 102, the first adhesive layer 16 is elastically deformed to the second adhesive area A2, and the lower end surface 4a of the wall material 4 and The first adhesive layer 16 is adhered without any gaps. At this time, since the thickness of the first adhesive layer 16 changes due to elastic deformation, even if the floor material 102 or the wall material 4 is distorted, the gap between them can be filled.
Next, as shown in FIG. 24C, when the wall material 4 is pulled up from the floor material 102 in order to correct the position of the wall material 4, the first adhesive layer 16 is stretched while adhering to the wall material 4. In this way, since the flooring material 102 and the wall material 4 are adhered via the first adhesive layer 16, even if the flooring material 102 is bent due to a load, the flooring material 102 and the wall material 4 There are no gaps between them, and watertightness is maintained. On the other hand, if packing had been used instead of the adhesive layer, if the floor material flexes and there is no room for the packing to collapse, a gap will form between the packing and the wall material, impairing watertightness. There is a risk that it may occur.

Furthermore, as shown in FIG. 24D, when the wall material 4 is pulled up further, the interface between the wall material 4 and the first adhesive layer 16 peels off, and the first adhesive layer 16 The second adhesive area A2 is almost restored to the form before being adhered to the wall material 4 (first adhesive area A1). As described above, the adhesive force between the first adhesive layer 16 and the floor material 102 is stronger than the adhesive force between the first adhesive layer 16 and the wall material 4. Therefore, when the wall material 4 is pulled up, the interface between the first adhesive layer 16 and the wall material 4 is separated, and the first adhesive layer 16 remains on the floor material 102 side.
Moreover, the breaking strength of the first adhesive layer 16 itself is made larger than the adhesive force between the first adhesive layer 16 and the wall material 4 and the adhesive force between the first adhesive layer 16 and the floor material 102. Therefore, as shown in FIG. 24C, when the first adhesive layer 16 is stretched, the first adhesive layer 16 itself will not be broken. Moreover, since the first adhesive layer 16 still maintains its adhesiveness even after the wall material 4 is peeled off, the wall material 4 can be re-attached.

As described above, in this embodiment, the first adhesive layer 16 for adhering the flooring material 102 and the wall material 4 is formed on the flooring material 102 side, and the first adhesive layer is formed on the wall material side. The workability of assembly is improved compared to the previous case. That is, if the first adhesive layer is formed at the lower end of the wall material, it is easy to accidentally attach the first adhesive layer of the wall material to an unintended position on the floor material during assembly, and the wall The material becomes difficult to handle.
Further, when the wall material 4 is peeled off from the floor material 102 after being attached once, if the first adhesive layer 16 remains on the wall material side as shown in FIG. 24E, the wall material 4 may be difficult to handle. It becomes difficult. Further, when one of the plurality of wall materials 4 adhered to the floor material 102 is peeled off from the floor material 102, the first adhesive layer 16 is attached to the wall material 4 adjacent to the wall material 4 to be peeled off. is suppressed by. Therefore, as shown in FIG. 24E, the risk of the first adhesive layer 16 peeling off from the flooring 102 can be further reduced.

According to the plumbing equipment unit room 100 according to the second embodiment of the present invention described above, with respect to the inner bottom surface 119a of the support recess in the support member 119 watertightly provided in the wall-mounted recess 118 of the flooring material 102, The first adhesive layer 16 is formed in advance by continuously applying a heated and liquefied adhesive in a linear manner.
The first adhesive layer 16 formed on the inner bottom surface 119a of the support recess in the support member 119 in the wall-mounted recess 118 of the floor material 102 is attached to the joint (lower end surface 4a) of the wall material 4. After the temperature drops to room temperature, it is bonded to the flooring 102 via the first adhesive layer 16.
Moreover, when the flooring material 102 and the wall material 4 are joined in this way, the support member 119 in the wall mounting recess 118 of the flooring material 102 is formed in a continuous linear shape with respect to the inner bottom surface 119a of the support recess. A load such as a force applied to the first adhesive layer 16 against the load (self-weight) of the wall material 4 itself or the joint between the wall material 4 and the floor material 102 (the support member 119 in the wall mounting recess 118) acts. Therefore, once the floor material 102 and the wall material 4 are adhered via the first adhesive layer 16, the first adhesive layer 16 is attached to the support recess of the support member 119 in the wall mounting recess 118 of the floor material 102. The inner bottom surface 119a is deformed from the first adhesive area A1 to the second adhesive area A2 adjacent to the outside thereof.
Thereafter, when the adhesive between the flooring material 102 and the wall material 4 is removed, the entire first adhesive layer 16 is not broken, and the inner bottom surface 119a of the support recess of the support member 119 in the wall mounting recess 118 of the flooring material 102 is removed. By deforming from the second adhesive area A2 toward the state C1 where it is previously adhered to the first adhesive area A1, it remains on the flooring material 102 side and becomes ready for re-adhesion.
That is, when assembling the flooring material 102 and the wall material 4, after the flooring material 102 and the wall material 4 are once adhered via the first adhesive layer 16, the floor material 102 and the wall material 4 are attached to each other in order to correct the position of the wall material 4. 102 and the wall material 4, the first adhesive layer 16 which had been deformed into the second adhesive area A2 of the inner bottom surface 119a of the support recess in the support member 119 in the wall mounting recess 118 of the floor material 102 deforms toward the first adhesive area A1 of the inner bottom surface 119a of the support recess in the support member 119 in the wall-mounted recess 118 at the joint of the flooring 102 before adhesion with the wall material 4. Therefore, the entire first adhesive layer 16 remains on the flooring 102 side without being broken, and becomes ready for re-adhesion.
Therefore, when reassembling the flooring material 102 and the wall material 4, the first adhesive layer 16 may be reapplied to the flooring material 102 or the wall material 4, or the first adhesive layer 16 may be removed from the factory. Since there is no need to newly procure coated flooring material 102 or wall material 4, work efficiency can be improved.
In addition, by simply reassembling the removed wall material 4 to the floor material 102 in the correct position, It is possible to reliably ensure watertightness between the flooring material 102 and the wall material 4 while reusing the entire first adhesive layer 16 that has been previously adhered to the first adhesive area A1 of the bottom surface 119a). As a result, ease of assembly can be improved.
As a result, the floor material 102 and wall material 4 of the plumbing equipment unit room 1 can be easily assembled.
