Description

TECHNICAL FIELD OF THE INVENTION The present invention relates to a wall structure capable of forming a large continuous surface capable of arbitrarily taking joints on an outer wall or an inner wall of a building and preventing cracks or the like from occurring.

Technical background of the invention and its problems Conventionally, in order to form an outer wall of a building, particularly a high-rise building, a standardized wooden wool cement board or slate board of about 90 cm x 180 cm (3 shaku x 6 shaku) There have been cases where a large number of wall plates such as a calcareous plate are stretched, and a paint or the like is applied as a finishing layer on the wall plate to form a wall structure.

However, in such a wall structure, the joint portion, which is a joint between the wall plates, is formed in a seam-like shape on the outer wall surface of the building, and its design appearance is not preferable. The fact that there are many such joints made it easy for rainwater to enter the joints. In order to make these joints invisible from the outside, and to improve waterproofness, a paint as a finishing layer is applied thickly to cover the joints, and the joints are filled with caulking material or sealing material. It is also conceivable to apply the paint later as a finishing layer. However, in such a wall structure, the finishing layer cannot follow the minute movement that occurs differently in each wall plate due to external force such as wind force, thermal stress, vibration force, etc., and this finishing layer, especially the joint portion There is a possibility that cracks such as cracks may occur in the portion located on the surface. If cracks occur in the finishing layer, rainwater or the like may enter through the cracks and accelerate the deterioration of the wall.

In order to prevent such cracks in the finishing layer, the wall structure shown in FIG. 5 is also known. In this wall structure,
The mesh 4 is stretched on the surface side of the joint portion 3 of the wall plate 2 such as a slate plate attached to the steel frame 1 and the adhesive 5
Is applied to form a reinforcing portion 7 for restricting relative movement between the wall plates 2, and then the surface of the wall plate 2 is subjected to cement spray coating to form a finishing layer 6.

However, even with the reinforcing portion 7 in such a wall structure, it is not possible to prevent the minute movement of the wall plate 2 to which an external force acts, and there is a possibility that the finishing layer 6 may still be cracked.

Such an inconvenience as described above may similarly occur when a large continuous large surface is formed on the inner wall of the building.

Purpose of the Invention The present invention has been made in order to solve various inconveniences associated with the above-described conventional technology at once, and the outer wall and the inner wall of a building have few joints, or joints can be arbitrarily set. An object of the present invention is to provide a wall structure that can form a continuous large surface, is resistant to cracks, and is easy to repair.

SUMMARY OF THE INVENTION In order to achieve such an object, the present invention has a plurality of walls in which a cushioning material having a larger area than the wall plate is stretched on the surface of the wall plate stretched so as to bear an external force. Adhesive so as to cover the joints formed in the plate and the joint portion of these wall plates, to form a finishing layer in close contact with the surface of this cushioning material, the cushioning material, between the wall board and the finishing layer It is characterized by having elasticity capable of absorbing relative movement.

According to such a wall structure of the present invention, since a large-area cushioning material is attached between the stretched wall plate and the finishing layer, the joints between the wall plates are not visible in appearance. It is possible to form a continuous large surface having few joints and having arbitrary joints. Moreover, when the joint portion is formed on the finishing layer for decoration, it can be easily performed by changing the thickness of the finishing layer.

Further, since the cushioning material having elasticity absorbs the relative minute movement between the wall plate and the finishing layer on which an external force acts, cracks or the like are unlikely to occur in the finishing layer, and rainwater or the like may enter from there. Less.

Furthermore, when wall repair work is required to prevent rain leaks, etc., to prevent rain leaks, simply replace the cushioning material and re-form the finishing layer without replacing the wall plate itself. It is possible to easily carry out the necessary repair work.

Detailed Description of the Invention Hereinafter, the present invention will be described in detail with reference to the embodiments shown in the drawings.

FIG. 1 is a sectional view of an essential part of a wall structure according to an embodiment of the present invention,
2 and 3 are enlarged cross-sectional views of the main part of the wall structure shown in FIG. 1, and FIG. 4 is a cross-sectional view of the main part of the wall structure according to another embodiment of the present invention.

In an embodiment of the present invention shown in FIG. 1, a wall plate 10 such as a foamed lightweight concrete plate (ALC plate) is attached to a steel frame 1 to apply external force such as wind force, thermal stress, seismic force, and vibration force. It is stretched to bear the burden. Caulking material 11 or the like is packed on the surface side of the joint portion 3 which is a joint of each wall plate 10 so as to close the gap. Further, in the central portion of the joint portion 3, a reinforcing bar 11a filled with a mortar material is provided.
Is stretched.

As shown in detail in FIG. 2, a cushioning material 13 is adhered to the entire surface of the wall plate 10 stretched in this way through an adhesive layer 12. The adhesive layer 12 is the wall plate 1 in this embodiment.
Although it is formed on the entire surface of 0, the present invention is not limited to this and may be formed so as to be scattered. As the adhesive forming the adhesive layer 12, for example, a mixture of cement and resin such as resin mortar, and in some cases, as a commonly used adhesive, for example, urethane type or epoxy type is used.

As the cushioning material 13, a necessary shear deformation capacity (shear elasticity) is required depending on the amount of deformation of the wall plate due to heat, lateral load, etc., the rigidity of the finishing layer, the relative deformability with respect to the wall plate, and the like. , Foamed plastics, high-density knitted fabric, rubber, soft plastics and the like are used, and vinyl chloride-based foamed plastics are particularly preferable from the viewpoint of waterproofing or fireproofing.
The inner thickness of the cushioning material 13 can be set arbitrarily, and the thickness thereof is determined by the relative displacement amount of the wall plate and the finishing layer and the shear elasticity of the cushioning material, but from the viewpoint of economical efficiency, practicality and the like. To 3 to 20 mm, particularly preferably 5 to 10 mm. Further, as shown in FIG. 1, this cushioning material 13 is
It has a larger area than the wall plate 10, and is arranged so that the joint portion of the cushioning material 13 and the joint portion 3 formed by the wall plate 10 do not overlap.

On the surface of the cushioning material 13 stretched in this way, a finishing sheet is attached via an adhesive layer 14 similar to the adhesive layer 12, and a finishing layer 15 is formed. As the sheet (finishing sheet) forming the finishing layer constituting the finishing layer 15, a resin film made of vinyl chloride or acrylic, a metal foil, a metal plate, or the like is used. In addition, thin tiles can be applied.

The finishing layer 15 formed by such a finishing sheet is
It will have a waterproof effect by itself. In the finish layer thus attached, the joint portion 3 of the wall plate 10 becomes invisible. If a joint is to be formed on the finishing layer 15 for decoration, a concave portion 16 may be formed on the surface of the cushioning material 13, and the finishing layer 15 may be formed along the concave portion 16.

According to the wall structure according to the present embodiment as described above, since the cushioning material 13 is mounted between the wall plate 10 and the finishing layer 15, the joints between the wall plates 10 do not appear in appearance, and depending on the case, Makes it possible to form a continuous large surface having no joint portion. Moreover, when forming the joint portion for decoration on the finishing layer 15, it can be easily performed by changing the wall thickness of the cushioning material 13 or the like, and by attaching a tile or the like, regardless of the joint portion of the wall board. You can also take joints arbitrarily.

Further, since the relative small movement in the direction of the arrow A shown in FIG. 2 between the wall plate 10 and the finishing layer on which an external force acts is absorbed by the deformation of the elastic cushioning material 13, the finishing layer 1
It is less likely that a crack or the like will be generated in 5 and rainwater or the like will enter from there.

Furthermore, in the case where the wall needs to be repaired in order to prevent rain leaks and the like, even if minute cracks 17 that cannot be observed with the naked eye are generated on the wall plate 10 itself as shown in FIG. The repair work necessary to prevent rain leaks and the like can be easily performed by simply reattaching the cushioning material 13 and the finishing layer 15 without replacing the plate 10 itself.

It should be noted that the present invention is not limited to the above-described embodiments, but can be variously modified within the scope of the present invention.

For example, as shown in FIG. 4, the finishing layer 15a formed on the surface of the cushioning material 13 may be formed by applying resin-reinforced glass reinforced mortar (GRC) or the like. As the coating material for forming the finishing layer 15a, other than GRC,
For example, carbon fiber mixed mortar or the like may be used. Furthermore, a mesh made of glass fiber, carbon fiber, or the like may be placed on the surface of the cushioning material 13, and resin mortar may be applied onto the mesh to form a finishing base. After that, a simple coating is applied to the surface of the finishing layer 15a to complete the wall structure. To form the joints 18 and 19 for decoration on the surface of such a finishing layer 15a, for example, the finishing layer 15a before being cured is pressed, or the joints of the cushioning material are formed. The recess 20 may be provided, and the finishing layer 15a may be applied and formed along the recess 20.

Further, in each of the above-described embodiments, the case where a large continuous surface is formed on the outer wall of a building has been described, but the present invention is not limited to this, and it is also possible to form a large continuous surface on the inner wall of a building. It can be applied similarly.

As described above, according to the present invention, a large-area cushioning material is adhered to the surface of a wall plate stretched so as to bear an external force, and a plurality of wall plates stretched and the same are attached. It seems to cover the joints formed by the wallboard,
A finishing layer is formed on the surface of the cushioning material, and the cushioning material is characterized by having elasticity capable of absorbing relative movement between the wall plate and the finishing layer. Therefore, the joint portion is formed on the outer wall or the inner wall of the building. It is easy to form a continuous large surface with excellent decorativeness, cracks are less likely to occur in the finishing layer, and it is possible to prevent deterioration of the wall due to intrusion of rainwater, etc. It has an excellent effect that the durability of can be improved. In addition, when repairing such a wall structure, it is almost always necessary to exchange the finishing layer and the cushioning material, so that the repair work is easy and inexpensive.
