Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for vertically adhering outer wall materials in a narrow area.

[0002]

2. Description of the Related Art When a building is set up in a position where the gap between adjacent buildings is extremely small, it is difficult or impossible to carry out outer wall construction from the outside of the building. Therefore, conventionally, outer wall boards were also constructed from the inside of the building. . That is, conventionally, as shown in FIG.
First, the waterproof sheet A is attached to the wall base surface by the width of one wall plate B, and then the wall plate B is horizontally arranged along the front surface of the pillar C.
A break is provided in the waterproof sheet A at the stop D, the tip D ₁ is projected from this break, and the stop D is nailed to the side surface of the pillar.
The fastener D tip D ₁ is engaged to the tip of the wallboard B, then bonded by a width of the as well as fixed wallboard wallboard B again a piece of tarpaulin A above B, the upper wall plate While sequentially repeating the work of engaging the lower end of B with the stopper D tip D ₁ , the wall plate is arranged and fixed above the wall surface, and finally the sealant is applied from the inside of the building to the breakage part provided in the waterproof sheet A. It was due to the work of waterproofing.

[0003]

[Problems of the prior art] However, in the case of the above-described mounting structure, when the wall plates are sequentially joined from the outer wall foundation portion toward the ceiling and the wall plates are extended to the outside when the position is near the ceiling, there is a particularly narrow space. Due to the positional relationship, there is a problem in that it may be extremely difficult to simply extend the wall plate out of the room.
In addition, when the outer wall of the beam portion between the ceiling above the first floor and the floor below the second floor is constructed, it may not be possible to attach the above-mentioned fastener D, and it is necessary to implement a special attachment structure according to the situation of the site. There was a drawback that the construction was very troublesome.

[0004]

SUMMARY OF THE INVENTION In view of the above problems, the present invention can reliably fix the outer wall of a building on a narrow land, which has a very small gap with an adjacent building, with a small number of steps, and also has good waterproofness. The purpose of the present invention is to provide a structure for vertically adhering outer wall material in a narrow land that can be used.

[0005]

That is, the structure for vertically sticking the outer wall material in the narrow land according to the present invention is such that the wall plate fastening metal fitting having the hooking claw extending to the outer surface side of the furring strip where the wall plate is applied to the outer surface is provided. It is fixed to the outer wall base material such as the furring strip, pillar or braces, and the joint edge of the wall plate vertically arranged at the tip of the hooking claw of the wall plate fastening metal fitting is locked, and the other joint edge of the wall plate is fixed. It is characterized in that wall plates are joined together.

[0006]

In the present invention, the wall plates are vertically arranged, and the vertically arranged wall plates are nailed to the outer wall base material such as a furring strip, a pillar or a brace, etc. To be fixed by engaging with the joining edge. Since each wall board is arranged vertically, it is covered with one wall board in the height direction, so that the wall can be easily attached between the first and second floors of the building. Since the corners of the outer wall of the building are attached in the horizontal direction where the wallboards are joined, there is always a space for feeding the wallboards out of the room, and workability is good. Therefore, the workability is greatly improved and the joints of the wall plates are vertical joints, so that the waterproofness can be secured without providing a waterproof seal.

Embodiments of the present invention will be described below. 1 is a vertical sectional view of an embodiment of the present invention, FIG. 2 is a horizontal sectional view of FIG. 1, and FIG. 3 is a perspective view of a stopper.

[Example] Thickness 20 mm, width 45 cm, length 300 cm
1A of the wall plate 1 of the present embodiment, which has a solid-shaped joining step portion 1A at the widthwise edge,
As shown in FIG. 1 and FIG. 2, the wall plate 1 having 1B is provided with a furring strip 2A.
It has a width of 3 cm, which is vertically arranged on the front side, extends from the substrate 3A to the front side on the furring strip 2A side surface and the pillar side surface 2B, and is bent along the contour of the actual joining step 1A. A fastener 3 having a hooking claw 3B as shown in FIG. 3 is fixed by a nail 4, and the hooking claw 3B is joined to the wall plate 1 to project the joining edge 1A.
The wall plate 1 was fixed to the pillar by engaging with. In addition,
The lower end 1C of the wall plate has a structure in which it is supported by the base draining metal fitting 5 as in the conventional case. Then, the other edge of the wall plate 1 to be joined is joined by engaging the joining edge 1B, and similarly, the side edge thereof is fixed by fastening with the fastener 3 in the same manner as described above. A test wall with a height of 320 cm and a height of 300 cm was constructed.

[Comparative Example] As shown in FIG. 5, a waterproof sheet A is attached to the base surface of a wall by the width of one wall plate B, and then a pillar C is formed.
After arranging a wall board B with a thickness of 20 mm, a width of 45 cm, and a length of 300 cm on the front side as a horizontal arrangement, make a break in the waterproof sheet A of the fastener D and project the tip D ₁ from this break. Then, the fastener D is nailed to the side surface of the pillar, and the tip D ₁ of the fastener D is attached to the wall plate B.
Wall plate B engaged with the upper end of the plate and then fixed as described above
While repeatedly repeating the work of reattaching the waterproof sheet A to the upper part of the wall by the width of one wall plate B, the horizontally arranged wall plate is arranged and fixed to the upper part of the wall surface, and finally the building is attached to the breakage part provided in the waterproof sheet A. Width 300 cm by mounting sealant from inside 18 height 18
A 2 cm test wall was constructed.

When the time required for constructing the test wall surface by the same worker was measured, it was 20 minutes at the longest until the completion of all the work in each of the examples, whereas it was at least 40 minutes in the comparative example. It took a minute, and the construction time was about doubled. Next, when shower water was sprinkled from the outer surface of the upright wall surface and a water leakage test was conducted, there was no abnormality after one hour in all of the examples, whereas in the comparative example, the waterproof sheet A was used. It was confirmed that water leaked from the defective portion of the sealant coating on the fractured part of No. 1 though it was slight.

[0012]

As described above, according to the present invention, when the wall plates are attached in a narrow area, the wall plates are vertically arranged and joined together. A space for feeding out is always secured, and therefore workability is greatly improved. In addition, the vertical arrangement provides good drainage at the joints and ensures reliable waterproofing without the need to attach a waterproof sheet to the back surface of the wallboard, and the construction is easy because there is no need to install a waterproof sheet. Become.
