Description

The present invention relates to a method for laying a floor laying mat such as a hot water heating mat on the upper surface of a floor base of a building structure, and a floor laying mat.

As a specific example of the floor laying mat, there is a hot water heating mat as described in Patent Documents 1 and 2, for example. This hot water heating mat has a structure in which a concave groove portion is formed on the upper surface portion of the mat main body portion and a hot water pipe is housed in the concave groove portion.
When such a hot water heating mat is laid on a floor base such as a floor slab of a building structure, it is customary to screw the hot water heating mat to the floor base and fix it. On the other hand, even when screwing is attempted, if the hot water heating mat and the floor base are not adhered to each other, problems such as floor noise may occur. Therefore, conventionally, an adhesive is applied to the back surface of the hot water heating mat using a brush, the hot water heating mat is adhered to the upper surface of the floor base, and then screwing is performed.

However, in the above-mentioned prior art, there is room for improvement as described below.
That is, the work of applying the adhesive to the back surface of the hot water heating mat using a brush is troublesome and the work time is long. Further, when the hot water heating mat is placed on the floor base after the adhesive is applied to the back surface of the hot water heating mat, the adhesive may be improperly adhered to an area other than a predetermined portion of the floor base. .. Therefore, the work of arranging the hot water heating mat at a predetermined place needs to be performed carefully, which is not easy. In addition, the time required for such work is long.
Such a defect is not limited to the hot water heating mat, but may also occur when another type of floor laying mat such as a heat insulating mat or a sound insulating mat is laid on the floor base.

The present invention has been conceived under the above-mentioned circumstances, and is a method for laying a floor laying mat and a floor, which can appropriately simplify and speed up the laying work of the floor laying mat. The challenge is to provide laying mats.

In order to solve the above problems, the following technical measures are taken in the present invention.

In the method of laying the floor laying mat provided by the first aspect of the present invention, the floor laying mat is adhered to the upper surface of the floor base of the building structure via an adhesive, and the underfloor is fixed by using a driving fixing member. A method of laying a floor laying mat to be fixed to the ground, wherein the floor laying mat is provided with an adhesive-sealing portion in which the adhesive having fluidity is sealed on the back surface side of the mat main body. In the state where the floor laying mat is placed on the upper surface of the floor base in use, when the driving fixing member is driven into the floor laying mat, at least a part of the adhesive sealing portion is broken and the bonding is performed. It is characterized by having a step of flowing out the agent into the gap between the floor laying mat and the floor base.
Here, the driving fixing member is a member capable of driving and fixing the floor laying mat to the floor base, and corresponds to, for example, screws, nails, staples, and the like.

According to such a configuration, the following effects can be obtained.
That is, when the driving fixing member is driven into the floor laying mat to fix the floor laying mat to the floor base, the adhesive flows out from the adhesive encapsulation part, and the floor laying mat is placed under the floor using this adhesive. Can be glued to the ground. Therefore, unlike the above-mentioned conventional technique, it is possible to eliminate the work of applying the adhesive to the back surface of the floor laying mat using a brush. In addition, when the floor laying mat is placed at a predetermined location on the floor base, the back surface of the floor laying mat is not coated with an adhesive, so the floor laying mat may be aligned at the predetermined location. It can be easily done. As a result, it is possible to appropriately simplify and speed up the laying work of the floor laying mat and reduce the labor of the operator.

The floor laying mat provided by the second aspect of the present invention is a floor laying mat that is adhered to the upper surface of the floor base of a building structure via an adhesive and is fixed to the floor base by a driving fixing member. The adhesive sealing portion provided on the back surface side of the mat main body portion and in which the adhesive having fluidity is sealed is provided, and the driving fixing member is driven into the adhesive sealing portion. It is characterized in that it is configured so that it sometimes breaks and the adhesive can flow out.

The floor laying mat having such a structure is suitable for carrying out the method of laying the floor laying mat provided by the first aspect of the present invention, and is the same as the method of laying the floor laying mat described above. The effect can be obtained.

In the present invention, preferably, on the surface portion of the floor laying mat, a mark indicating the driving location of the driving fixing member is provided directly above the adhesive sealing portion.

According to such a configuration, when the driving fixing member is driven into the floor laying mat, if the driving fixing member is driven into the above-mentioned mark portion, the driving fixing member hits the adhesive sealing portion. Therefore, it is possible to ensure that the adhesive-sealed portion is broken and to further improve the work efficiency.

In the present invention, preferably, the adhesive encapsulation portion is a container in which the adhesive is housed.

According to such a configuration, the adhesive encapsulating portion can be easily provided on the floor laying mat, and the cost of the floor laying mat can be reduced.

In the present invention, preferably, the container is a bag-shaped container constructed by using a flexible packaging material, and the bag-shaped container is provided in a state of protruding downward from the back surface of the mat body portion. Therefore, when the floor laying mat is placed on the floor base, the weight of the mat main body is received, and when the bag-shaped container breaks, the adhesive is brought to the outside by the weight. It can be compressed and deformed so that it can be extruded.

According to such a configuration, when the bag-shaped container is broken by driving the driving fixing member, the adhesive can smoothly flow out from the bag-shaped container to the outside in a large amount. Therefore, it is more preferable to appropriately and firmly bond the floor laying mat and the floor base by using the adhesive.

In the present invention, the adhesive encapsulation portion preferably includes a plurality of adhesive encapsulation portions dispersed and provided at a plurality of locations of the mat main body portion.

According to such a configuration, it is possible to appropriately bond a wide range of the back surface of the mat main body portion to the floor base without a large bias while reducing the individual volumes of the plurality of adhesive sealing portions.

Other features and advantages of the present invention will become more apparent from the following description of embodiments of the invention with reference to the accompanying drawings.

It is a top view which shows an example of the hot water heating mat as a floor laying mat which concerns on this invention. (A) is a partially omitted cross-sectional view of the line IIa-IIa of FIG. 1, and (b) is an enlarged view of a main part of (a). It is a partially omitted cross-sectional view which shows the folding state of the hot water heating mat shown in FIG. (A) and (b) are cross-sectional views of a main part showing an example of a method of laying a hot water heating mat shown in FIGS. 1 and 2. It is sectional drawing of the main part which shows the other example of this invention. It is sectional drawing of the main part which shows the other example of this invention.

Hereinafter, preferred embodiments of the present invention will be specifically described with reference to the drawings.

The hot water heating mat A shown in FIGS. 1 and 2 corresponds to an example of a floor laying mat according to the present invention, and is a pair of left and right mat main bodies 1, and recessed grooves 10 formed on the upper surface of each mat main body 1. It includes a hot water pipe 2 arranged inside, a heat transfer sheet 3 laminated on the upper surface of each mat main body 1, a plurality of adhesive encapsulation portions 4, and a plurality of marks 5 for driving fixing members.

The mat main body 1 has a substantially rectangular plate shape in a plan view having an appropriate vertical thickness, and is made of a resin such as a foamed resin having excellent heat insulating properties. The plurality of concave groove portions 10 have an opening shape on the upper surface, and have a shape having a straight portion and a curved portion as appropriate in a plan view. The hot water pipe 2 is made of a flexible resin, is housed in the concave groove portion 10, and is provided in a pattern arrangement that is distributed in substantially the entire area of the mat main body portion 1 in a state of no large bias. The end of the hot water pipe 2 is an inlet portion 2a or an outlet portion 2b of hot water.

The heat transfer sheet 3 is made of a material having excellent heat transfer properties, such as aluminum foil, and is adhered to the upper surface portions of each of the pair of mat body portions 1 so as to straddle both of them. The pair of mat main bodies 1 are connected to each other via the heat transfer sheet 3. When the hot water heating mat A is laid on a floor base 6 such as a slab floor of a building structure, one side surface of each of the pair of mat main bodies 1 is in contact with each other or is arranged side by side. During transportation or storage before laying, as shown by the solid line in FIG. 3, one mat body 1 is set in a double-folded shape laminated on the other mat body 1 to make it compact. It is possible to plan. At that time, a part 30 of the heat transfer sheet 3 is in a bent state and functions as a hinge portion.

The plurality of adhesive encapsulating portions 4 are portions for adhering the back surface of the mat main body portion 1 to the floor base 6, and in the present embodiment, they are configured by using a sheet-shaped or film-shaped flexible packaging material. , A bag-shaped container in which a fluid adhesive 41 is housed (enclosed). Each adhesive encapsulating portion 4 is adhered to the back surface of the mat main body portion 1 using an adhesive tape or an adhesive (an adhesive different from the adhesive 41), and projects downward from the back surface. The weight of the mat body 1 or the hot water pipe 2 acts on the adhesive sealing portion 4 as a load, but the adhesive sealing portion 4 has a strength that does not easily burst due to such a load. .. Preferably, the adhesive-sealed portion 4 has a flat shape so that the overall thickness of the hot water heating mat A does not become too large.

The plurality of adhesive-sealed portions 4 are preferably provided on the back surface of each mat main body portion 1 in a vertically and horizontally dispersed arrangement so as to have a uniform distribution as much as possible. In the vicinity of the boundary portion 19 between the pair of mat body portions 1, the adhesive sealing portions 4 are arranged close to each other.

The mark 5 for the driving fixing member is a portion indicating an appropriate driving position when the driving fixing member 7 is driven into the hot water heating mat A, and is a position directly above the adhesive sealing portion 4 on the surface of the heat transfer sheet 3. It is provided in. However, since it is necessary to avoid driving the driving fixing member 7 into the hot water pipe 2, such a position is avoided. The mark 5 is provided by displaying an appropriate symbol or figure such as a circle mark or a cross mark by printing, attaching an adhesive tape, or other means. The driving fixing member 7 is, for example, a screw such as a concrete screw, a nail, a staple, or the like.

Next, an example of a method of laying the hot water heating mat A on the floor base 6 and its operation will be described.

In a state where the hot water heating mat A is arranged at a predetermined position on the floor base 6, as shown in FIGS. 4A and 4B, the driving fixing member 7 is driven into the hot water heating mat A from above. The driving position is a position where a mark 5 for the driving fixing member is provided. In the process of driving the driving fixing member 7, the driving fixing member 7 penetrates the adhesive sealing portion 4 and breaks the adhesive sealing portion 4. As a result, as is well shown in FIG. 4A, the adhesive 41 in the adhesive sealing portion 4 flows out into the gap between the back surface of the mat main body 1 and the upper surface of the floor base 6. Since the weight of the mat body 1 and the hot water pipe 2 acts on the adhesive sealing portion 4, the adhesive sealing portion 4 is compressed and deformed by the weight described above when the adhesive sealing portion 4 is broken. As a result, the adhesive 41 is forcibly extruded from the adhesive sealing portion 4. Therefore, it is possible to allow a large amount of the adhesive 41 to flow out from the adhesive sealing portion 4 without waste and spread it over a wide area in the gap.

As shown in FIG. 4B, when substantially the entire amount of the adhesive 41 flows out from the adhesive sealing portion 4, the adhesive sealing portion 4 (bag-shaped container) becomes a sheet material 4', and its thickness is considerably small. Become. Therefore, the presence of the sheet material 4'does not hinder the laying of the hot water heating mat A. As described above, since the adhesive encapsulation portion 4 is provided at a plurality of locations in a substantially uniform distribution arrangement, the adhesive 41 can be spread over substantially the entire back surface of the mat main body portion 1. In FIG. 4B, the adhesive 41 is shown protruding from one side of the mat body 1 within the range of reference numeral S, but another floor is laid on one side of the mat body 1. By arranging the members, it is possible to prevent the adhesive 41 from sticking out as described above. Further, even if the adhesive 41 protrudes, another flooring material such as a flooring material is further laid on the hot water heating mat A, so that the protruding portion of the adhesive 41 is covered by this flooring material. It can be covered properly.

As described above, according to the present embodiment, in addition to being able to fix the hot water heating mat A to the floor base 6 by using the driving fixing member 7, the hot water heating mat A can be fixed by using the adhesive 41. It can be adhered to the floor base 6. Therefore, it is possible to prevent problems such as floor noise from occurring. On the other hand, it is not necessary to apply the adhesive 41 to the back surface of the hot water heating mat A using a brush or the like. Therefore, the work of laying the hot water heating mat A can be simplified, the required time can be shortened, and the labor burden on the operator can be reduced.

5 and 6 show other embodiments of the present invention. In these figures, elements that are the same as or similar to those of the embodiment are designated by the same reference numerals as those of the embodiment, and duplicate description will be omitted.

In the embodiment shown in FIG. 5, a downward opening-shaped recess 12 is formed on the back surface of the mat main body 1, and the adhesive-sealed portion 4 as a bag-shaped container is housed in the recess 12.
According to such a configuration, it is difficult to obtain the action of pushing out the adhesive 41 by positively acting the weights of the mat main body 1 and the hot water pipe 2 on the adhesive sealing portion 4, but the adhesive sealing portion 4 It is possible to prevent the mat from protruding downward from the mat body 1 or to reduce the downward protrusion dimension. This is advantageous in reducing the overall thickness (thickness before laying construction) of the hot water heating mat A.

In the embodiment shown in FIG. 6, the adhesive 41 is housed in the downward opening-shaped recess 12 formed on the back surface of the mat main body 1, and the lower opening of the recess 12 is a closing member such as a sheet. It is blocked by 42. This portion is the adhesive sealing portion 4A. When the driving fixing member 7 is driven, the closing member 42 breaks and the adhesive 41 flows out.
According to such a configuration, since the container for accommodating the adhesive 41 is not used, it is possible to simplify the configuration of the hot water heating mat A.

The specific configuration of each work process of the floor laying mat laying method according to the present invention can be variously changed within the scope intended by the present invention. Similarly, the specific configuration of each part of the floor laying mat according to the present invention can be variously redesigned within the scope intended by the present invention.

The floor laying mat referred to in the present invention means a mat laid on the floor base of a building structure. Therefore, in addition to hot water heating mats, flooring mats also include, for example, heat insulating mats, soundproofing (soundproofing) mats, flooring mats, and other decorative mats. Therefore, the shape, material, size, etc. of the mat body are not limited.
The floor base referred to in the present invention is a base on which a floor laying mat such as a hot water heating mat is stretched among the parts constituting the floor of a building structure, and corresponds to a slab floor or the like. Further, in the remodeling of a house or the like, there may be a case where an additional hot water heating mat is laid on the existing flooring floor, but in such a case, the above-mentioned flooring floor corresponds to the floor base. It will be.

As will be understood from the above-described embodiment, the adhesive encapsulating portion may have either a configuration using a container for accommodating the adhesive or a configuration using no such container. When a container is used, the container is not limited to a bag-shaped container, and can be, for example, a non-flexible box-shaped container. The adhesive may be any as long as it has fluidity so that it spreads when the adhesive encapsulation portion is broken, and the specific type and component thereof are not limited.

When the adhesive encapsulation portions are provided at a plurality of locations, the sizes of the plurality of adhesive encapsulation portions and the amount of the adhesive do not necessarily have to be the same. For example, an adhesive encapsulation portion with a large amount of adhesive is provided at the center of the mat body, and an adhesive encapsulation with a small amount of adhesive is provided near the end of the mat body. It can be provided.
As described above, the driving fixing member referred to in the present invention is a member capable of driving and fixing the floor laying mat to the floor base, but it is also possible to apply a member having a configuration different from that of screws, nails, and staples. ..
