Description

[Detailed Description of the Invention] The present invention relates to an improvement in the joint structure of the joint part in the attachment part when attaching a handrail or other incidental member to the outside of a building.

As is well known, in buildings such as prefabricated houses, when installing handrails, balconies, and other ancillary members on the outside of the building, the attachment arm of the ancillary member protrudes from the building side, and the attachment arm is pre-installed. A construction method is used in which pre-assembled auxiliary members are attached from outside the building.

In this case, the mounting arm is usually installed to protrude from the frame structure of the building, so the mounting arm protrudes outward from the joint part, and the mounting arm penetrates the joint plate and is exposed to the outside. Although it has a protruding structure, there is a problem with the sealing performance at the penetration part between the joint plate and the mounting arm, and conventional caulking treatment has poor durability and there is a risk of water leakage inside from this part.

The present invention solves these problems, eliminates the problem of water intrusion, and provides a highly durable sealing effect.The main feature of this invention is that it is possible to install handrails and other accessories on the outside of the building. At the joint portion where the mounting arm protrudes from the frame frame structure in order to attach the component from the outside of the building, a sealant is installed on the mounting arm between the frame frame structure and the joint plate via a sealant mounting washer. The joint plate, which is provided with a sealing material on both sides of the outer wall panel, is crimped by a connecting portion of an auxiliary member supported by the mounting arm.

The present invention will be described in detail below with reference to the illustrated embodiment. Fig. 1 shows an example of an incidental member implementing the present invention and a part to which the member is attached, and as shown in the figure, a window on the outside wall 1 of a building is shown. When installing an accessory member 3 such as a handrail on the outside of the opening 2, etc., the mounting arm 5 is made to protrude outside through the joint plate 4 from the framework (column material) frame on both sides of the window opening 2. A construction method is adopted in which the attachment arm 5 connects and supports the connecting frame portion 6 of the accessory member 3 by tightening bolts, etc., so that the accessory member 3 can be easily installed from the outside of the building. Seal at the penetrating portion of the mounting arm 5 can only be achieved by processing means such as filling the through hole with caulking material, and a sufficient and durable sealing effect cannot be obtained.

In such a case, the present invention is applied to a framework (column material) on the outside wall of a building, as shown in FIGS. 2 and 3.
A frame structure 7, for example, a pair of C-shaped steel members 7a, 7b facing each other, and inside the frame 7, both art materials 7a, 7a.
In a frame structure including a frame joint piece 8 etc. which is installed between the frame joint pieces 8 and the like, the mounting arm 5 that penetrates the joint plate 4 from the piece 8 and projects to the outside is connected to the frame joint 7 and the joint plate. A sealing material mounting washer 9 and a sealing material 10 are fitted and installed on the mounting arm 5 between the joint plate 4 and the mounting arm 5 in an overlapping manner. The connecting frame portion 6 of the accessory member 3 illustrated in FIG. 1 is attached to the mounting arm 5. It is possible to connect the mounting arm 5 to the mounting arm 5 and to make it crimped by the same portion 6. For this purpose, as shown in FIG. By adjustingly fastening both holes 5a, 5a with fasteners such as bolts 12, nuts 13, washers 19, etc., the connecting frame portion 6 is advanced toward the joint plate 4 side, and the front edge 6 thereof is moved forward.
Press the joint plate 4 to the joint side using b, and seal the sealing material 10.
The sealing materials 4b and 4b are brought into close contact with each other under sufficient pressure.

According to the present invention, in the joint space between the frame 7 and the joint plate 4, the sealing material 10 tightly seals the insertion portion of the mounting arm 5 of the joint plate 4 through support by the washer 9, thereby reliably preventing flooding accidents. It strongly prevents it.

At this time, the sealing material 10 has no part exposed to the outside world, has sufficient weather resistance, does not deteriorate or age over a long period of time, and can fully demonstrate its waterproof performance, and also retains the lining of the washer 9. This prevents the shape from deforming and reliably maintains the sealed shape, thereby preventing problems such as water intrusion into the interior through the arm insertion hole 4a of the joint plate 4, causing rust and weakening of the frame structure side. There isn't.

However, the mounting washer 9 of the sealing material 10 can be easily attached to the protruding mounting arm 5, and the elongated hole 5a in the connecting frame portion 6 and the mounting arm 5 (this elongated hole is on the connecting frame portion 6 side) Due to the presence of the front edge 6b of the connecting frame portion 6, the joint plate 4 can be sufficiently crimped to the sealing material side, and in combination with the sealing material 4b with the outer wall panel 11 on both side edges, the joint plate 4 can be easily obtained, and the presence of the elongated holes makes it easy to absorb and adjust dimensional variations, making it an excellent structure for the joint portion of the accessory member 3 having the attachment arm 5.
