Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a mounting device for inserting and fixing a joint material into a joint space between adjacent exterior wall panels.

(Conventional technology) Conventionally, it was developed in 1983 as a joint material attachment device.
A device described in Publication No. 41494 is known.

The structure of this invention consists of a vertical column that stands upright with a predetermined interval left and right, a plate-shaped body whose lower end is rotatably pivoted at a predetermined position on the front surface of the vertical column, and this pivot-mounted part. A stopper is provided to engage the opposite side edges of the panel, and a clamp is provided on the upper end of the plate-like body so as to be rotatable relative to the plate-like body and to hold the protruding plate on the back side of the joint material. It consists of a mounting member.

(Problem to be solved by the invention) The stopper provided to engage the opposite side edges of the panel and the clamping member that clamps the protruding plate on the back side of the joint material are composed of separate members, so the parts As the number of points increases, installation becomes more complicated.

(Means for Solving the Problems) A joint material installation device according to the present invention installs a band-shaped watertight material at the joint between the end faces of external wall panels attached to the front surfaces of adjacent frameworks with a predetermined gap between them. This is a mounting device for inserting and fixing a joint material having a substantially T-shaped cross section and a leg portion at the center of the back surface of the shaft assembly, by bending one spring plate body into a substantially U-shaped cross section. A shaft contact portion having a width slightly wider than the gap and a pair of opposing arm pieces are formed,
The center portion of each tip of each of these arm pieces is cut outward to form an elastic fixing portion that is wider than the width of the joint, and each tip of this elastic fixing portion is bent inward to form an elastic fixing portion that is opened to the outer wall. It is made into a locking claw portion that locks on each end face of the panel, and the opposing intervals of the tip portions of these arm pieces other than the elastic fixing portion are sandwiched, so that the tip portions sandwich the leg portions of the joint material. This is a holding part.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings.

It is for inserting and fixing a joint material 5 having a substantially T-shaped cross section, and is formed from a single spring plate.

This mounting device 1 is constructed by bending a single spring plate into a substantially U-shaped cross section, so that a shaft abutting portion 6 having a width slightly wider than the gap between the shaft assemblies 2, 2 is constructed.
and a pair of opposing arm pieces 7, 7 are formed,
These arm pieces 7, 7 are formed into elastic fixing parts 8, 8 by cutting and raising the central part of each tip outward to form elastic fixing parts 8, 8 which are opened wider than the width of the joint 4, and each of the elastic fixing parts 8, 8 The tips are bent inward to form locking claws 9, 9 that lock onto the respective end surfaces 31, 31 of the outer wall panels 3, 3, and the elastic fixing portions 8, 8 of these arm pieces 7, 7. Excluding each tip part 10,1
The end portions 10, 10, 11, 11 are sandwiched by opposing intervals of 0, 11, 11, and serve as clamping portions 12, 12 that clamp the leg portions 51 of the joint material 5.

A joint material 5 is provided on the inner surface side of the holding parts 12, 12.
The locking claws 13 that engage with the tips of the leg portions 51 of the

Next, a procedure for installing the joint material 5 using the installation device 1 as described above will be explained.

Here, the connecting part of the plurality of external wall panels 3 that constitute the external wall of the building and the connecting part of the frame-shaped framework 2 that attaches and fixes these external wall panels 3 are at the same position, that is, the external wall panel The joints 4 between the frames 3 and the gaps between the frames 2 are made to overlap.

First, by inserting the legs 51 of the joint material 5 between the clamping parts 12 and 12 of the mounting device 1, a plurality of the mounting devices 1 are attached at appropriate intervals in the longitudinal direction of the joint material 5 (see Fig. 1). .

Next, the joint material 5 with the attachment device 1 attached as described above is inserted into the joint space 15 from the joint 4 with the attachment device 1 first. Then, each mounting device 1

Waterproof joint sheet 1 is placed in the recess 23 that occurs at the entrance between 2 spaces.
At the same time, each mounting device 1...
The elastic fixing parts 8, 8 are compressed against the elastic force,
The locking claws 9, 9 at each tip are locked to the respective end surfaces 31, 31 of the outer wall panels 3, 3 forming the joint 4. As a result, the joint 4 is closed by the watertight material 52 of the joint material 5. Note that the joint material 5 can also be easily removed from the joint 4.

(Effect of the invention) The joint material installation device of the present invention as described above has a part that clamps the legs of the joint material, an elastic fixing part and a locking claw part that engage the end faces of both adjacent exterior wall panels forming the joint. Since they are integrally formed, construction work is easy, and since they can be integrally formed, the number of parts is small, making it convenient to handle, and it also has the advantage that it can be manufactured at low cost.
