JPH0640772Y2 - Backup material filling tool - Google Patents

Description

[Detailed Description of the Invention] [Industrial application] Concrete, glass, aluminum, iron, tile, mortar, wood and all other joints of buildings take into consideration various vibrations such as earthquakes and expansion and contraction of the above-mentioned members. Then, attach the joints with the joints. Thus, in order to prevent rainwater and the like from entering through the joints, a predetermined backup material is pushed in, and a caulking material is filled on the backup material to finish the wall surface.

The present invention relates to an improvement of a backup material filling tool used for pushing the backup material, which is the first step of the wall surface finishing.

[Conventional technology]

During the finishing process of the inner and outer wall surfaces, the backup material is filled in the back of the caulking material, and the joint material is a string-like sponge having elasticity slightly larger than the joints of the wall surface as a backup material. Push in,
It will be used as a stopper for the next caulking process. The inventor of the present invention has found that as a tool for filling the above-mentioned backup material
The tool released in the issue was developed, but there are still insufficient points.

[Problems to be solved by the device]

Originally, the above-mentioned backup material was filled with an appropriate rod material without using a special tool, and it was difficult to make the indentation uniform by hand, but the backup material previously proposed by the present inventor. Using a filling tool made it possible to fill the backup material relatively easily. However, the uniform depth of pushing of the backup material was not constant due to the handle holding angle, and it was difficult to push the backup material uniformly.

[Means for Solving the Problems]

According to the present invention, a rotating shaft is penetrated at one end of a rod-shaped handle at a right angle to the handle, a main roller is rotatably screwed to one end of the rotating shaft, and an obtuse angle is formed at the opposite end of the rotating shaft. A plate-shaped bracket, which is formed in a V shape and has small rollers rotatably mounted in the same direction on a shaft parallel to the main roller at both ends, is fixed to the rotary shaft. Is adjustable through a long hole provided at the center of the bracket so that the backup material is always pushed in at a constant depth.

[Action]

To the joints of all the joints of the building, a slightly thick backup material based on these joints is held by the handle of the filling tool and pushed by the main roller. At this time, the two small rollers roll on one end surface of the wall surface, and if the two rollers constantly roll on the wall surface due to the rocking of the bracket, the main roller rolls regardless of the angle between the wall surface and the handle. The backup material is pushed in by the gap difference between the moving surface and the rolling surface of the two small rollers. And this pushing depth can be easily adjusted by adjusting the mounting position of the bracket.

〔Example〕

The rotating shaft (6) is penetrated through one end (2) of the handle (1) formed in a rod shape at a right angle to the handle (1), and the main roller (3) is attached to one end of the rotating shaft (6). A plate-shaped bracket (5) rotatably screwed with a butterfly screw (7) and formed in an obtuse V shape at the other end of the rotary shaft (6) is provided with a long hole (9) at its central apex. ) Through a wing nut (8) so that the handle (1) can be swingably screwed. Small rollers (4) and (4) are rotatably attached to both ends of the bracket (5) in the same direction as the main roller (3).

In order to fill the backup material (A) with the above tool, a main roller (3) having a width slightly narrower than the joints of all joint wall surfaces (B) and (B ') of the building is used, and the backup is used. The material (A) is pushed in by the main roller (3) as shown in FIG. At this time, the small roller (4)
(4) is rolled on one wall surface (B) and the backup material (A) is pushed into the required depth (l), but this depth (l) loosens the wing nut (8). It is adjusted by moving the bracket (5) of the length of the slot (9).

If the backup material is pushed in and filled using this tool adjusted in this way, the depth of the backup material pushed in is always l regardless of whether the operator's hand is facing upward or downward.
Fixed to the depth of.

[Effect of device]

The backup material filling tool of this invention is a simple and extremely easy-to-use tool, and it requires no skill to fill the backup material, which is the basis of caulking of joints to prevent rainwater and the like from entering from all joints of a building. Instead, it is constructed by rolling two small rollers on one wall surface, and the filling depth is obtained by rolling two small rollers on the wall surface at the same time. By placing the small roller on the front side of the handle, the indentation depth can be ensured, and it is possible to use the joint at the corner formed by the plane and the elevation. Further, since the main roller is replaced and the bracket is fixed with a thumbscrew or the like, no tool is required, and the replacement and adjustment can be easily performed at the work site.
