Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a closing structure between exterior wall panels at an inside corner of an exterior wall.

[Background Art] In a prefabricated house, the outer wall 4 is formed by erecting and connecting a plurality of outer wall panels 3 on a foundation 8 etc., and the outer wall panels 3 are connected to each other at the corner portions of the outer wall 4. , a support 9 whose side end is fixed to the foundation 8 etc. as shown in FIG.
This is done by combining. When the inner corner side of the outer wall 4 faces outdoors, it is necessary to close the gap between the outer wall panels 3 at the inner corner, but conventionally this was done as shown in Figure 6. I was getting used to it. That is,
The exterior wall panel 3 is formed by pasting face materials 2 on both sides of a frame material 1 made of shaped steel, and the frame material 1 is provided so as to protrude from the side edge of the face material 2.
0 from both sides of the main body 12 having an L-shaped cross section.
1, 11 are extended and formed, and this joint material 10 is arranged between the inner corners of the outer wall panels 3, 3, and the fixing pieces 11, 11 at both ends of the joint material 10 are fixed to each outer wall panel 3, 3. The joint material 10 is fixed by bringing it into contact with the protruding parts of the frame materials 1, 1, and then nailing or riveting this fixing piece 11 to the frame material 1. I tried to close it by attaching it between 3 and 3. However, in this case, the joint material 10 is installed in a narrow corner of the outer wall 4, and the nailing or riveting is done with respect to the frame material 1, which is the part hidden by the facing material 2. The work of nailing and riveting and drilling pilot holes for these are extremely difficult.
There was a problem that construction was difficult.

[Purpose of the invention] The present invention has been made in view of the above points, and provides a closing structure for the inside corner of an exterior wall, which allows the installation of joint material without the need for nailing or riveting. The purpose is to

[Disclosure of the invention] However, the closing structure of the inside corner of an external wall according to the present invention is such that the facing member 2 is attached to both sides of the frame member 1 to form the outer wall panel 3, and the frame member 1 is attached from the side edge of the outer wall panel 3. The outer wall 4 is formed by connecting the pair of outer wall panels 3 at substantially right angles at their side ends, and the front panel 1
The side pieces 14 are extended indoors from both ends of 3 to form a joint material 5 having a substantially U-shaped cross section, and the ends of each side piece 14 are folded back to the outside to extend the contact pieces 6 to the outdoor side. This joint material 5 is provided between the side end surfaces of the facing material 2 of each external wall panel 3 at the inner corner of the external wall 4.
are arranged so that the tips of each side piece 14 of the joint material 5 are brought into contact with the surface of the portion of the frame material 1 of each outer wall panel 3 that protrudes from the face material 2, and each tip of the contact piece 6 of the joint material 5 is The parts are pressed against the side end surfaces of the facing material 2 of each outer wall panel, and caulking material 15 is filled between the outer surface of the side piece 14 of the joint material 5 and the side end surface of the facing material 2 of the outer wall panel 3. The above object is achieved by using a joint material 5 having such a structure.The present invention will be described in detail below with reference to examples.

The joint material 5 is arranged from both ends of the front piece 13 to the side pieces 14,
The side pieces 14 are extended over the entire length at an angle slightly larger than a right angle (about 105°) to form a substantially U-shaped cross section.
From each tip of the panels 4 and 14, the contact pieces 6, 6 are folded back over the entire length at an angle of about 30°. The joint material 5 is formed by bending a steel plate and setting the vertical length to be almost equal to the height of the exterior wall panel 3, so that the side pieces 14 and the contact pieces 6 have elastic bending deformation.
The frame material 1 is formed by assembling steel beams into a square frame.
The frame is formed by attaching face materials 2, 2 to both sides of the frame, with the peripheral edge of the frame material 1 projecting slightly outward beyond the peripheral edge of the face material 2.

By connecting the outer wall panels 3, 3 to the pillars 9 by connecting their side ends to the support 9 in the same manner as shown in FIG. The closing between the outer wall panels 3, 3 at the corner portion of the outer wall 4 is performed as shown in FIG. That is, when the joint material 5 is pushed between the facing materials 2, 2 of the adjacent exterior wall panels 3, 3, the contact pieces 6, 6 are elastically deformed as shown by the arrow a, and the joint material 5 is pushed into the facing materials 2, 2.
When the joint material 5 is pushed in in this way, both ends of the joint material 5 (side piece 1
4, 14) is the frame material 1 of the outer wall panels 3, 3,
1, the deformation of the abutting pieces 6, 6 is elastically restored, and the tips of the abutting pieces 6, 6 are elastically pressed against the side end surfaces of the face members 2, 2.
Therefore, by contacting both ends of the joint material 5 with the surfaces of the frame materials 1, 1 and pressing the contact pieces 6, 6 against the side end surfaces of the facing materials 2, 2, the joint material 5 is attached to the outer wall panels 3,
Therefore, the joint material 5 can be attached between the outer wall panels 3 and 3 without using nails or rivets.
Further, the outer surfaces of the contact piece 6 and the side pieces 14 are filled with a caulking material 15 to perform waterproofing and finish.

3 and 4 show other embodiments,
In this product, the joint material 5 extends from both ends of the front piece 13 over the entire length at an angle larger than a right angle (approximately 135°), so that the cross section is approximately U-shaped. It is formed into a mold, and tongue-like contact pieces 6, 6 are further folded back and extended at predetermined intervals from the tips of side pieces 14, 14, which are both ends of this joint material 5. The joint material 5 is formed by bending and forming an iron plate so that its vertical length is approximately equal to the height of the outer wall panel 3. In this case, when closing the corner part of the outer wall 4, as shown in FIG. , so that both ends of the joint material 5 (tips of the side pieces 14, 14) are brought into contact with the surfaces of the frame materials 1, 1 of each of the outer wall panels 3, 3, and in this state, the third of the contact pieces 6, 6 Hit the part indicated by arrow b in the figure in the direction of the arrow with a punch, etc., deform the contact pieces 6, 6 so as to spread them, and insert the tips of the contact pieces 6, 6 on the sides of the face materials 2, 2 of each outer wall panel 3, 3. Make sure to press it against the end surface. Therefore, both ends of the joint material 5 are brought into contact with the surfaces of the frame materials 1, 1, and contact pieces 6 are brought into contact with the side end surfaces of the facing materials 2, 2.
6, the joint material 5 is held and fixed between the outer wall panels 3, 3, and the joint material 5 is attached to the outer wall panels 3, 3 without using nails or rivets.
This means that it can be installed in between. Further, the outer surface of the side piece 14 is filled with a caulking material 15 to perform a waterproof treatment and finish.

[Effect of the invention] As described above, in the present invention, the side pieces are extended indoors from both ends of the front piece to form a joint material having a substantially U-shaped cross section, and the tips of each side piece are Fold it back to the outside and extend the contact piece to the outside.
This joint material is arranged between the side edges of the facing material of each external wall panel at the inside corner of the external wall, and the tip of each side piece of the joint material is placed on the surface of the part of the frame material of each external wall panel that protrudes from the facing material. At the same time, each tip of the contact piece of the joint material is pressed against the side edge surface of the facing material of each outer wall panel, so that the contact of both ends of the joint material against the surface of the frame material and the contact of the facing material The joint material can be held and fixed between the exterior wall panels by pressing the contact piece against the side end surface, and the joint material can be attached between the exterior wall panels without the need for nails or rivets, making construction easier. It is easy to install, and the joint material can be installed with the entire joint between the side edges of the facing material of the exterior wall panel, so that the joint material does not protrude beyond the facing material of the external wall panel toward the outdoors. There is no risk that the joint material will stand out and spoil the appearance of the exterior wall due to the lack of joint material.Moreover, the joint material can be made from a single board by bending the side pieces and the contact piece. This material can be produced at low cost. In addition, since caulking material is filled between the outer surface of the side piece of the joint material and the side edge surface of the facing material of the exterior wall panel, waterproofing between the joint material and the facing material of the exterior wall panel can be ensured. In addition, the joint material acts as a backup material when filling with caulking material, eliminating the need to use a separate backup material.
