DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wall structure of a building using a large decorative board made of natural or artificial marble or ceramic for a wall surface of the building, and a method of constructing the same.

[0002]

2. Description of the Related Art Conventionally, it has been difficult to use natural or artificial marble or ceramic panels for building exteriors.
It is widely used as a technique for increasing the solid feeling of buildings, but in recent years, relatively thin and large panels have been provided due to advances in processing and production techniques. Such thinner and larger exterior panels meet various demands such as effective use of resources, cost reduction, and improvement in design, but on the other hand, they are relatively easily cracked by impact loads. Problems have arisen.

In order to solve such a problem, there has been proposed a construction wall material (hereinafter referred to as an "integrated panel") in which a folded metal base plate having a corrugated cross section is integrally fixed to the back surface of a thin exterior decorative plate. (For example, Japanese Patent Application Laid-Open No. 6-212772).
issue). The above proposal is excellent in terms of the effect of reinforcing the backing of a thin exterior decorative panel, but each integrated panel is individually integrated with airtightness and watertightness by top and bottom covers. Therefore, it has the following problems. That is, a space is formed between the back surface of the decorative plate and the folded plate base due to the wavy shape of the folded plate base. However, since the spaces of the integrated panels vertically adjacent to each other are not continuous, there is no continuity. In addition, rainwater or the like that has intruded from joints of the decorative board cannot flow down and drain smoothly using the space. In particular, when the outer wall surface is constructed on an inclined surface due to restrictions on the diagonal lines of the building, or when constructed as a roof surface, water leakage due to aging of the joint seals and the like leads to a water leakage accident. In addition, if the decorative board is made of a material having water absorbency such as a ceramic tile, once it absorbs water, it becomes difficult to diffuse water due to a non-permeable decorative layer such as a glaze on the surface. There is a risk of causing frost damage such as falling off. Furthermore, since the air cannot be expected to have fluidity in the space, there is a high risk that the space will be in a high-temperature and high-humidity state in spring or summer and the corrosion of the folded metal plate base will be accelerated.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned circumstances, and an object thereof is to use a relatively thin and large decorative panel on the wall of a building to improve the structure of the building. Provided is a wall structure of a building using a large decorative panel and a method for constructing the wall, which makes it possible to reliably reinforce the decorative panel when constructing the wall and to use the space behind the decorative panel for drainage and ventilation. Is to do.

[0005]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention relates to a method for forming a relatively thick and large decorative board such as a stone board, a cement board, a ceramic tile, etc. A wall structure of a building used for a wall surface, a base plate having a wavy cross section is laid on the frame of the building so that the wave space is vertically continuous, and the crest of the base plate is An adhesive layer for attaching a decorative board, a receiving metal fitting for receiving at least a lower end of the decorative board of the construction reference stage on the construction target wall is provided, and the decorative board and the adhesive layer provided on the base board are used to attach the decorative board to the surface of the base board. Attach,
The gist is that a space layer communicating vertically is formed between the decorative plate and the base plate. In such a configuration, the back surface of the decorative plate is reinforced by the base plate, and the water entering the back surface side of the decorative plate flows down by the vertically continuous space layer formed between the decorative plate and the base plate. The hot and humid state can be eliminated by discharging the air and allowing the air to flow in the back space of the decorative board. In addition, since the receiving bracket has a structure that supports at least the decorative board of the construction reference step on the construction target wall surface, the positioning at the time of attaching the decorative board becomes easy, and the peeling after the attachment is more reliably prevented. .

The thickness and size of the relatively thin and large decorative board are not particularly limited, but as an example, the thickness is about 4 to 12 mm and the size is about 600 × 600 mm to One having a size of about 1200 × 3000 mm is exemplified. Further, the material of the decorative board itself is not particularly limited. For example, it is described in a stone board, a cement board, a ceramic tile, a solar panel, and a previously proposed Japanese Patent Application No. 9-342837 by the present applicant. It also includes a panel body made of a cured product of the composition.

The base plate having a corrugated cross section is not particularly limited in material, but is most typically a metal forming material having a corrugated cross section, and has a plate thickness of about 0.4 to 1.2 mm. .
The size of the base plate with a corrugated cross section is usually one size larger than the decorative plate due to the arrangement of the overlap allowance for forming the base surface in a watertight manner. When the surface is as small as the above, no polymerization allowance is required. In addition, when the length of the construction target wall is limited to about 10 m, it is also possible to provide a base plate as a long material without providing a longitudinal overlap margin. The base plate is not limited to a type in which a stacking allowance is provided and the stacking allowances of the adjacent base plates are overlapped and laid, for example, the peripheral edge of the base plate formed to be approximately the same size as the decorative plate In addition, an elastic fitting portion which is fitted to a peripheral edge of an adjacent base plate may be provided, and the elastic fitting portion may be laid by an elastic fitting type known in this field. The stacking allowance in the case where the base plates are connected by stacking depends on the location of the wall surface and regional rainfall, but it is 50 mm or more for vertical wall surfaces and 300 or more for inclined wall surfaces such as roof surfaces or heavy rainfall areas. It is preferable that The base plate may be supported by a frame along the back surface, and the ridge may be fixed with a fixing tool such as a screw or a rivet, or in the case of a vertical wall, the valley may be fixed directly to the skeleton with a waterproof screw or the like. . Note that the base plate may be vertically long and the decorative plate may be horizontally long.

It is preferable to provide a heat insulating layer on the back surface of the base plate, and the heat insulating layer is formed of conventionally known various foaming materials such as urethane, styrene and phenol, and glass wool.

The receiving metal fittings provided on the crests of the base plate accurately determine the mounting position (horizontal line) of the decorative plate and stabilize the fixing and mounting work of the decorative plate.
The base plate is provided at an appropriate position on the crest of the base plate so as to be able to support at least the lower end of the decorative plate of the construction reference stage. Here, the construction reference step is a step when the construction of the decorative board is started, and thereafter, the step of performing the upper and lower steps based on the step. In other words, when a decorative board having a predetermined standard size is allocated to a construction target wall surface, not all decorative boards can be set to the predetermined standard size, and the adjustment may be performed at the lowermost step, the uppermost step, or both. For example, when the bottom decorative panel is adjusted to be smaller than the specified standard size,
Usually, the second stage is the construction standard stage, and the upper stage and the lower stage are constructed sequentially. For design reasons, it is preferable that the tip of the receiving part of the receiving fitting does not protrude from the decorative surface. The size (width) of the receiving metal fitting is such that it extends over the entire length of the construction target surface in the case of an extremely short piece corresponding to one peak, or in the case of a medium piece attached in a bridge shape to a plurality of peaks. In the case of medium to long, in order to avoid that the decorative board is chronically moistened, cutouts or holes for drainage are provided at appropriate intervals. preferable. In addition, when the length of the decorative surface (wall surface to be applied) is large and there are many decorative boards,
Needless to say, when safety is required, it is better to provide a receiving metal fitting for each decorative panel. In addition, the receiving bracket is fixed to the base plate by bonding, welding, or using a fixing tool such as a rivet. The fixing may be performed either at the installation site or in advance at a factory or the like. Is also possible.

The adhesive layer provided on the crest of the base plate is a conventionally known elastic epoxy or urethane adhesive or adhesive tape. However, from the viewpoint of workability and long-term safety, the adhesive is It is preferable to use both the adhesive tape and the adhesive tape. That is, while the instantaneous fixing force is obtained by the adhesive tape, the long-term fixing force is enhanced by the elastic adhesive, and a strong fixing force is obtained over a long period from the initial stage of construction. In addition, since both the elastic adhesive and the adhesive tape have elasticity, even when the frame is displaced, it has a high follow-up property, and a wall having a high anti-seismic effect can be constructed. Adhesive tape is, for example, a rubber-based thick double-sided tape, before attaching the decorative board to the base surface,
Paste at multiple locations on the mountain. Note that, similarly to the receiving metal fitting, either the material may be attached to the base plate at the site or may be attached in advance.

[0011] A bridged joint plate is provided at the peaks of the base plate at intervals of the length of the decorative plate, and the width of the decorative plate is formed to be substantially an integral multiple of the pitch of the peaks of the base plate. By forming the portions on the crests of the base plate and on the joint plates, vertical joints and horizontal joints between the decorative plates can be similarly expressed, which is preferable in terms of design. Although the material of the joint plate is not particularly limited, it is preferable that the joint plate be of the same color and the same material as the base plate in consideration of the case where the joint material is not filled. A waterproof joint can be applied to the vertical joint and the horizontal joint with a conventionally known urethane seal or the like.

On the other hand, the width of the decorative plate is formed to be substantially an integral multiple of the pitch of the valleys of the base plate, and the joints of the decorative plate are formed on the valley space of the base plate, so that the vertical length between the decorative plates is reduced. It is preferable that the joints and the side joints be open joints because ventilation of the space on the back surface of the decorative board can be performed smoothly. In addition, when the open joint is used as described above, a water-retaining decorative board having a water absorption of at least 10% or more can be used.

The space layer formed between the decorative plate and the base plate, which communicates in the vertical direction, may be provided at its lower end with a conventionally known drainage structure such as a drainer. In addition, regarding the air circulation by the space layer, when filling the joint portion of the decorative board with the joint material, an intake structure also serving as the drainage structure is provided at a lower end of the space layer, and an exhaust structure is provided at an upper end thereof. It is good to comprise by means.

The base plate may be a square wave-shaped interior / exterior material that is already provided on a building frame. The decorative plate is attached to the surface of the interior / exterior material, and the decorative plate and the base plate ( A modified structure in which a space layer that is continuous in the up-down direction with the existing interior and exterior materials) may be formed. That is, claim 2
Is a wall structure of a building using a relatively thin and large decorative board such as a stone slab, a cement board, a ceramic tile, etc. for a wall of the building, the corner being provided on the building skeleton. The base material is a corrugated interior / exterior material, and the crest of the base plate is provided with an adhesive layer for attaching the decorative plate, and a receiving bracket for receiving at least a lower end of the decorative plate of the reference level on the target wall, The decorative plate may be attached to the surface of the base plate by the receiving metal and the adhesive layer provided on the base plate, and a space layer communicating vertically in the decorative plate and the base plate may be formed. In the case of such a configuration, when the wall surface to be constructed is constructed of square wave-like interior / exterior materials and the wave space is continuous in the vertical direction, the remodeling structure for attaching the decorative panel to the wall surface is required. At the same time as possible, an operation similar to the above-described operation according to claim 1 can be obtained.

[0034]

The wall structure of the building using the large decorative panel according to the present invention has the following effects because it is constructed as described above.

According to the first aspect, even if the decorative plate is relatively thin and large, the back surface is supported by the base plate having a corrugated cross section, so that a high surface strength is achieved. In addition, since a space layer is formed between the decorative board and the base board, which communicates in the up-down direction, water entering the back side of the decorative board can flow down and drain by the space layer, thereby preventing a water leakage accident and preventing the decorative board from being damaged. Is effective in preventing frost damage in cold regions when the material is water-absorbing. In addition, the space layer allows air to flow in the back space of the decorative board, thereby eliminating a high-temperature and high-humidity state, and effectively preventing the base board from accelerating corrosion. In addition, since a metal fitting for receiving the lower end of the decorative panel is provided at the construction reference level of the target wall, it is easy to align the decorative panel at the time of construction, improving workability, and also preventing peeling after construction. It has many effects such as effective functioning and high security.

According to a second aspect of the present invention, in the case where the wall surface to be constructed is constructed of an inner and outer material having a square wave shape and the wave space is continuous in the vertical direction, a modified structure for attaching the decorative board to the wall surface is adopted. The same effect as the first aspect can be obtained. In addition, an inexpensive image due to the existing interior / exterior material being a square-wave interior / exterior material can be renewed into a high-quality image by attaching a large decorative board.

According to the third aspect, the reinforcing layer provided on the back surface of the decorative board makes it difficult for the decorative board to be damaged even if it receives a local impact. In particular, it has a great effect of preventing the falling of medium-sized fragments which may lead to an accident if dropped, as well as the prevention of falling as large fragments.

According to the fourth aspect, since the adjacent base plates are laid on the skeleton of the building with their peripheral edges superposed on each other, the watertightness of the skeleton is improved, and the above-described water leakage accident, frost damage, corrosion promotion, etc. Can be more reliably prevented.

According to the fifth aspect, since the heat insulating layer is formed on the inner side of the decorative board via the space layer and the waterproof layer (base plate), a wall structure having high heat insulating properties can be obtained.

According to the sixth aspect, all the decorative plates attached to the base plate have a structure in which the lower ends are supported by metal fittings, so that the workability at the time of attachment and the safety after the attachment are higher.

According to the seventh aspect, by using the elastic adhesive and the adhesive tape together, the adhesive tape can provide the instantaneous fixing force required at the time of construction, and the elastic adhesive can enhance the long-term fixing force. Therefore, a strong fixing force can be obtained over a long period from the initial stage of construction. In addition, since both the elastic adhesive and the adhesive tape have elasticity, even if displacement of the skeleton occurs due to an earthquake or the like, the wall structure has a high follow-up property and a high anti-seismic effect.

According to the eighth aspect, in addition to the fixing force of the adhesive layer, a mechanical fixing force of the fixing device acts, and the fixing device further ensures the adhesive force of the elastic adhesive. The safety of fixing the decorative plate is further improved.

According to the ninth aspect, the exposure of the fixing tool is prevented by the fixing tool cover, so that the deterioration of the design property due to the use of the fixing tool can be improved.

According to the tenth aspect, the vertical joints and the horizontal joints between the decorative boards are located on the hills and the joint plates of the base plate, respectively. Is useful in buildings where is desired.

In the eleventh aspect, when the decorative board is made of a water-impermeable material or when the decorative surface is highly waterproofed, the joints between the decorative boards are waterproofed to cover two layers. As a result, an excellent waterproof layer is formed, so that the performance of rain is improved.

According to the twelfth aspect, since the vertical joints and the horizontal joints between the decorative boards are respectively located in the valley space of the base plate, the joints become open joints formed in the space, and the air layer generates air. By synergistic with the flow function, the ventilation of the space on the back side of the decorative board is performed more smoothly. Therefore, even in an environment in which the water does not diverge after water absorption and frost damage occurs, the divergence of the water can be effectively performed by the ventilation, and an accident such as breakage of the decorative board or falling off can be prevented. be able to.

According to the thirteenth aspect, since the constructed wall surface has water retention, rainwater gradually diffuses in the form of water vapor, water droplets, etc. without causing rainwater to flow down mainly on the roof surface, thereby preventing global warming. And prevent flood damage in urban areas.

Further, claims 14 and 15 are directed to a construction method for obtaining a wall structure exhibiting the effects of claim 1.
7 is a construction method for obtaining a wall structure having the effect according to claim 2, claims 16 and 18 are construction methods for obtaining a wall structure having the effect according to claim 7, and claim 19 is a construction method for obtaining the effect according to claim 8. Each of them can be suitably used as a construction method for obtaining a wall structure to be played.
