DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, an embodiment in which the present invention is embodied in a manner of building a wall panel made of lightweight cellular concrete (ALC) in a structural body will be described in detail with reference to the drawings. As shown in FIG. 1, in this embodiment, basically, a plurality of wall panels 11a and 11b are first laid in a horizontal direction through a vertical gasket 12a with respect to the structural body 10, and the lower layer The wall 13 is formed. Next, the lower wall 1
In the same manner as above, the upper wall panel 14a and the like are built above 3 to form the upper wall 15.

The above-mentioned basic building method is almost the same as the conventional technique, but in this embodiment, the building process is performed in the following order. First, any one lower layer wall panel 11a is fixed to the lower structural body 10a.
The wall panel 11a is fixed by a conventionally known fixing metal fitting.

As shown in FIG. 2, for the wall panel 11a fixed to the lower structural frame 10a as described above, the vertical gasket 1 is formed on the vertical edge face 20a extending in the vertical direction.
Join 2a. As shown in FIG. 3, the vertical gasket 12a has a hollow rod-shaped gasket body 17 made of an elastic material such as nitrile rubber or butyl rubber, and pressure-sensitive adhesive layers 18b, 18a integrated on the upper and lower surfaces thereof. The pressure sensitive adhesive layers 18a and 18b are covered with a covering sheet 19
a and 19b are respectively coated so that the pressure-sensitive adhesive does not exert its function to the outside when the gasket 17 is handled.

The lateral width of the covering sheets 19a, 19b is considerably wider than that of the gasket body 17, and as will be described later, when the covering sheet 19b is installed between two wall panels without peeling it off, the covering sheet 19b becomes By grasping and pulling a part thereof with a hand, the pressure-sensitive adhesive layer 18b can be peeled off.

Vertical gasket 1 for wall panel 11a
To join the 2a, one cover sheet 19a is peeled from the gasket body 17 and the exposed pressure sensitive adhesive layer 18a
As shown in FIG. 4, the vertical edge face 2 of the wall panel 11a is
The gasket 12a may be pressed and joined toward the 0a side. However, the uppermost end surface of the gasket body 17 is located slightly higher than the uppermost horizontal edge surface 20b of the wall panel 11a in order to exert the effects described later.

Further, a stepped portion 21 is formed on the vertical edge face 20a of the wall panel 11a of this embodiment in the middle in the thickness direction thereof. This is because the vertical gasket 12a is brought into contact with the stepped portion 21 to position the pressure-sensitive adhesive layer 18a, and then the vertical gasket 12a is attached to the vertical edge face 20.
This is for pressing and joining to a. In order to enhance the bonding performance of the pressure-sensitive adhesive layer 18a to the vertical fore edge surface 20a, when concrete powder adheres to the vertical fore edge surface 20a, it can be swept off or an appropriate adhesive can be applied to the same. You may apply an accelerator.

Next, while the vertical gasket 12a is still attached to the other covering sheet 19b, the optional gasket 1
Another one wall panel 11b built adjacent to the one wall panel 11a is brought into contact with the gasket 12a.
Then, after the setting position of the wall panel 11b to be fixed is finely adjusted so that the two wall panels 11a and 11b are flush with each other, the wall panel 11b is fixed to the structural body 10a.

In this state, as shown in FIG. 1, the covering sheet 19 is formed on the joint portion 16 between the two wall panels 11a and 11b.
Although b is held together with the gasket body 17 and the like, a part of the covering sheet 19b is exposed to the outside, so that the covering sheet 19b is grasped and the covering sheet 19b is peeled from the pressure-sensitive adhesive layer 18b. Then, the exposed pressure sensitive adhesive layer 18b and the wall panel 1
The vertical edge face 20a of 1b is joined.

In such a manner, a plurality of wall panels are successively built in the structural body 10a as shown in FIG. 5, so that a lower layer extending horizontally with respect to any one wall panel 11a. Can form the outer wall 13 (in FIG. 5, it is depicted that there is a gap between the two wall panels 11a and 11b, but the two are actually joined via the gasket 12a). .

Next, the horizontal edge face 2 extending in the uppermost horizontal direction of the wall panels 11a and 11b constituting the lower outer wall 13
As shown in FIGS. 6 and 7, a water draining plate 22 having a lateral L-shaped cross section is horizontally fixed to 0b by a pressure sensitive adhesive layer 23. The draining plate 22 is formed by bending a relatively thin metal plate, for example, a stainless steel plate, and the pressure sensitive adhesive layer 23 is adhered to the back surface thereof. The pressure-sensitive adhesive layer 23 is covered with a covering sheet (not shown) similar to the above-mentioned gasket, and if the sheet is peeled off and the draining plate 22 is pressed against the horizontal edge face 20b, the draining plate 22 becomes horizontal. At the same time as being joined to the small surface 20b, both of them are also joined in a state where the uppermost end surface of the gasket body 17 of the vertical gasket 12a described above is pressed slightly downward.

Subsequently, a horizontal gasket 12b having a diameter slightly larger than that of the vertical gasket 12a is fixed to the upper surface of the draining plate 22. This horizontal gasket 12
Basically, b is a gasket main body 24, pressure-sensitive adhesive layers 25a and 25b joined to both surfaces thereof, and a cover sheet 26 coated on the outside of the pressure-sensitive adhesive layers 25a and 25b.
(In FIG. 7, since the lowermost cover sheet is peeled off,
(Not drawn) and the material thereof is substantially the same as that of the vertical gasket 12a described above. Here, the equivalent diameter means the diameter when the cross-sectional shape is replaced with a circle having the same cross-sectional area as the cross-sectional area.

However, this horizontal gasket 12b
In FIG. 8, as shown in FIG.
6 is longer than half the horizontal width of the wall panel 11a, but shorter than the gasket body 24. And preferably, the pressure-sensitive adhesive layer 2 is formed so that a plurality of short covering sheets 26 partially overlap each other.
5b is covered. This means that when building a building without scaffolding, the covering sheet 26 is directed toward the outside of the building.
This is because it is difficult to pull in the direction indicated by arrow A as shown in. Also, if the covering sheet 2 is used inside the building,
When pulling 6, if the covering sheet 26 is too long,
A fixing metal member (not shown) for fixing the lower portion of the upper wall panel 14a to the structural body 10a interferes with the covering sheet 26.
This is because the work of peeling off is difficult. Further, if the cover sheet 26 is too long and breaks in the middle, it is necessary to work again to grasp a part of the cover sheet 26.

As shown in FIG. 1, after the horizontal gasket 12b is joined to the upper surface of the draining plate 22 without peeling off the uppermost cover sheet 26, the lower wall panel 11a is joined.
The upper-layer wall panel 14a is built on the gasket 12b, and the upper and lower structural frames 10a, 1
Fix at 0b. Then, the cover sheet 26 is pulled toward the inside of the building, that is, on the side of the structural body 10a, and peeled off from the pressure-sensitive adhesive layer 25b. Prior to fixing, the upper wall panel 14a is covered with the covering sheet 26 on the horizontal gasket 12b.
The two wall panels 11a and 14a are made flush with each other by making a slight sliding contact therewith.

The upper wall panel 14 fixed in this way
The vertical gasket 12a is fixed to the vertical edge surface 20a of a as described above. In this case, as shown in FIG. 8, the elastic body 27 is joined to the horizontal gasket 12b at a position where it is joined to the lower end surface of the vertical gasket 12a, and the lower portion of the vertical gasket 12a is slightly compressed with respect to the elastic body 27. So that they are joined together.

The width of the elastic body 27 is larger than the outer peripheral surface of the vertical gut 12a. Due to these factors, rainwater is prevented from entering the joint between the vertical gasket 12a and the horizontal gasket 12b. Thereafter, with respect to the upper layer wall panel 14a, the next wall panel (not shown) is built in the structural skeletons 10a and 10b via the vertical gasket 12a, as in the case of the lower layer wall panel,
The upper wall 15 is formed.

The construction work has been described in detail above, but according to this embodiment, it is possible to efficiently construct the wall panel in the structure of the building by a dry method without using mortar. Exert. In particular, the entire outer wall of the building can be easily made flush, and when there is only a narrow gap between the existing building and the building to be constructed, the effect is remarkable when the construction is performed without scaffolding.

The present invention follows the fundamental technical idea,
In addition, a part of the above-described embodiment can be modified and implemented as follows, as long as the effect is not significantly impaired. (1) The gasket may be applied to the wall panel as a single layer, but may be doubled. (2) The present invention can be applied to a concrete wall panel other than ALC as a wall panel, for example, a PC panel. (3) If the horizontal gasket is too long, it can be cut to a short length and transported in a short length, and can be used again in a proper length by the connecting means at the time of construction.

(4) The draining plate can also be made of a flexible material such as an aluminum plate, rubber or synthetic resin, and can be transported in a rolled state. When rubber or synthetic resin is used, it can be integrally molded with the gasket body. (5) It is not always necessary to bond the pressure-sensitive adhesive to the gasket on both sides of the gasket body in advance. It is also possible to apply an adhesive to the foreside of the wall panel, and to join the gasket to the adhesive and the surface on the side where the pressure-sensitive adhesive layer does not exist to fix the gasket to the foreside.

(6) When the effect of the gasket itself is fully exerted, the draining plate 22 can be omitted, and as shown in FIG. 10, when using the draining plate 22, a vertical gasket is used. The upper and lower end surfaces of 12a may be directly brought into contact with the draining plate 22 without being brought into contact with the horizontal gasket.
