Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wall structure in which a sheet-like wall material is attached to a wall panel used for an outer wall or an inner wall of a building, and the surface of the sheet-like wall material is free from wrinkles and bulges. Regarding the structure.

[0002]

2. Description of the Related Art A conventional structure for pasting a sheet-like wall material on a wall panel is as shown in FIG. That is, in the same wall structure, a plurality of wall panels 1 such as ALC panels are attached to a wall surface of a building (not shown), and a groove 2 for sealing is provided in a joint 2 formed by an adjacent wall panel 1. 3 sealing material for waterproofing 4
Is filled. Then, in order to even out the surfaces of the joints 2 of the wall panels 1, 1, another filling material 5 is further filled, and a sheet-shaped wall material 6 is attached so as to cover the joints 2. In addition, the joint 11 between the adjacent sheet-shaped wall members 6 and 6 is filled with the sealing material 12 or a joint sheet (not shown) is used for waterproofing and adjusting the appearance.

[0003]

However, in the above wall structure, since the joint 2 is located under the sheet-like wall material 6, when the interlayer displacement of the wall panel 1 due to traffic vibration or earthquake occurs, When the wall panel 1 expands and contracts due to changes in temperature and humidity, the surface of the sheet-shaped wall material 6 may wrinkle or swell, and the wall material 6 itself may peel off. In particular, since the wall panel 1 is often an ALC panel and the joint 2 is a wide expansion joint in consideration of its expansion and contraction, the surface of the sheet-like wall material 6 having different expansion and contraction characteristics is easily wrinkled. However, there was a problem that it spoiled the aesthetics of the wall.

Further, in the above conventional wall structure, the sheet-like wall material 6 is attached so as to cover the joints 2 of the wall panel 1, so that the attaching operation of the wall material 6 must be performed at the construction site in advance. There is also a problem that the construction process is complicated because the wall material 6 cannot be shipped in a state of being attached at the factory.

Further, at present, a stone-like texture is often used as the wall material 6, but since the thickness of the sheet-shaped wall material 6 is generally as thin as several millimeters, a structure in which this is simply attached to the surface of the flat wall panel 1 is used. Then, there was a problem that the solid feeling of the stone could not be reproduced.

Therefore, an object of the present invention is to prevent wrinkles and bulges on the surface of the wall material that occur at joints as the wall panel expands and contracts, further simplify the construction process, and make the stone-like sheet-like wall surface. The purpose is to propose a wall structure that can reproduce the texture of stone when wood is used.

[0007]

In a wall surface structure in which a sheet-shaped wall material is attached to the outer surfaces of a plurality of wall panels that form a wall surface of a building, the sheet-shaped wall material is attached to each wall panel. By forming a step on the outer surface of the end portion of the wall panel, forming a groove between the adjacent wall panels by this step, and constructing a wall surface structure in which the sheet-like wall material is attached to the side surface of the groove. , Solves the above problems.

Further, the joint formed on the bottom surface of the groove may have a wall surface structure which is covered with a tape-shaped wall material.

[0009]

In the wall structure of the present invention, since the sheet-shaped wall material attached to the plurality of wall panels is not continuous at the joint portion, wrinkles and swelling of the wall material surface caused at the joint portion due to displacement of the wall panel are prevented. can do. In particular, if the tape-shaped wall material is attached to the joint, the joint can be concealed without making the sheet-shaped wall material of the adjacent wall panel continuous.

Further, since the sheet-shaped wall material is independently attached to each wall panel, it is possible to perform the attaching process in advance in a factory. Furthermore, when a stone-like material is used as the sheet-shaped wall material, the sheet-shaped wall material attached to the side surface of the groove can give a three-dimensional effect to the wall surface of the building.

EXAMPLE Next, an example of the wall structure according to the present invention will be described.
It will be described with reference to the drawings. FIG. 1 is a perspective sectional view of a wall surface structure of the embodiment.

The wall structure of this embodiment is composed of a plurality of wall panels 1.
On the outer wall or the inner wall of the building that is constructed by combining
The sheet-like wall material 6 having a stone-like texture obtained by painting or printing a stone pattern is attached. The wall panel 1 is an ALC panel, and a joint 2 is formed between the wall panel 1 and an adjacent wall panel 1. The wall panel 1 may undergo interlayer displacement due to traffic vibration or an earthquake, and due to the nature of ALC (lightweight aerated concrete), it may expand or contract after installation, so the joint 2 absorbs the displacement. It is an expansion joint with a certain interval.

In the state where the wall panels 1 are combined, FIG.
As shown in FIG. 3, the sealing groove 3 is formed in the joint 2, and the waterproof sealing 4 is filled therein. Further, the groove 7 is formed on the stepped portions 1a, 1a formed on the upper surface of the end portion of the wall panel 1 so as to face each other.

A sheet-like wall material 6 is attached to the side surfaces 7a, 7a of the groove 7 in the same manner as the upper surface of the wall panel 1, and a bottom portion 7b of the groove 7 is flattened by a filled ceiling 4. The joint sheet 8 is attached to both sides so as to straddle the ceiling 4 and the wall panel 1, respectively. Then, a tape-shaped wall material 9 is attached to the upper surface of the sealing 4 so that both ends are hung over the joint sheets 8 on both sides. Therefore, the two side surfaces 7a, 7a and the bottom surface 7b of the groove 7 are covered with the sheet-shaped wall material 6, the tape-shaped wall material 9 and the joint sheet 8, respectively, and the surface of the wall panel 1 is not exposed.

The sheet-like wall material 6 to be attached to the side surface of the groove 7 is obtained by folding and attaching the sheet-like wall material 6 to be attached to the surface of the wall panel 1 and also to a separate sheet-like wall cut into strips. The material 6 may be attached. The joint sheet 8 may be attached to the sheet-shaped wall material 6 in advance, and the tape-shaped wall material 9 may have a stone-like pattern similar to that of the sheet-shaped wall material 6.

As described above, in the wall surface structure of this embodiment, the tape-shaped wall material 9 attached to the joint 2 is the wall panel 1.
Since it is independent of the sheet-like wall material 6 attached to the main body, even if the wall panel 1 is displaced, the wall materials 6 and 9 do not wrinkle or bulge at the joint portion 2.

At the construction site, after the wall panel 1 is attached, the joint 2 may be sealed, for example, and then only the joint sheet 8 and the tape-shaped wall material 9 may be attached. It is possible to use the sheet-shaped wall material 6 that has been attached in advance at the factory. Therefore, the work at the construction site can be simplified.

Furthermore, since the sheet-like wall material 6 attached to the side surfaces 7a, 7a of the groove 7 gives a three-dimensional effect to the wall surface, the texture of the stone material attached to the wall material 6 is emphasized, which is more aesthetically pleasing. The wall surface of the building can be configured.

Another embodiment of the present invention will be described with reference to FIGS. In the wall surface structure of FIG. 2, instead of the joint sheet 8 of the above-described embodiment, a sealing 10 is filled between the tape-shaped wall material 9 and the sheet-shaped wall material 6. The sealing 10 to be filled has a waterproof property and is also highly elastic. Therefore, even if the wall panel 1 is displaced, the tape-shaped wall material 9
It is possible to obtain the same effect as that of the above-mentioned embodiment without exerting an unreasonable force.

In the wall surface structure shown in FIG. 3, the angle of the step 1a formed on the wall panel 1 is made gentle. Step 1
The angle of “a” may be gentle as shown in FIG. In addition, of course, the depth and width of the groove 7 can be freely changed.

In addition to the above wall surface structure in the joint portion, a dummy groove structure having the same appearance as the joint portion can be provided in other portions of the wall panel 1. An example of the same structure is shown in FIG. 4, and the same dummy groove 17 as the joint portion of the above embodiment is provided on the surface of the wall panel 1. Then, the sheet-like wall material 6 is attached to the side surfaces 17a, 17a, and the joint sheet 8 and the tape-like wall material 9 are attached to the bottom portion 17b. As described above, by using the dummy groove structure, the design of the wall surface can be variously changed.

[0022]

As described above, according to the wall structure of the present invention, it is possible to prevent wrinkles and swelling of the wall material surface due to the displacement of the wall panel. In particular, if the tape-shaped wall material is attached to the joints at the bottom of the groove, the joints can be hidden and the wall structure can be made more beautiful.

Further, the wall structure of the present invention enables the sheet-shaped wall material to be attached in a factory, and simplifies the work at the construction site. Furthermore, when a stone-like sheet material is used as the sheet-shaped wall material, the depth of the groove causes the stone material to have a feeling of solidity, and a wall surface rich in the texture of the stone material can be configured.
