Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a gas stopper fixture for fixing a gas stopper to a mounting hole provided in a wall or floor of a building.

[Prior Art] When constructing a building, interior work usually begins after gas piping and structural work are completed. The work to install the gas valve at the end of the gas piping will be done after the interior work is completed. Therefore, a gas plug mounting hole is pre-drilled in the wall or floor of the gas plug mounting portion, corresponding to the end of the gas pipe.

FIGS. 5 and 6 show conventional means for fixing a gas plug to this mounting hole.

In this conventional example, a fixed plate 03 which is bent in two and whose diameter is larger than the diameter of the mounting hole 02 is suspended in the mounting hole 02 of the floor 01 by a string 04 and inserted into the back side (Fig. 5). The method is to open the gas valve 06 and screw the fixing bolt 07 into the bolt hole 05 of the gas valve 06 to fix it (FIG. 6). In this way, the floor (or wall)
Since there is no need to attach the gas valve directly to the floor or wall using screws or the like, there is an advantage that there is no need to damage the floor or wall.

[Problems with the prior art] However, in the conventional example described above, it takes time and effort to insert the fixing plate into the back side of the floor 01, align the tips of the bolts 07 with the bolt holes 05 of the fixing plate 03, and screw them in. The disadvantage is that the workability is very poor.

[Purpose of the present invention] The present invention is proposed in view of the above points.
The purpose is to propose fixing devices for gas valves that are easy to install.

[Structure and operation of the present invention] As a technical means for achieving the above object, the present invention proposes a gas stopper fixing device having the following structure.

The rear end of the body, which has a slit that expands outward and eventually bends when subjected to compression, is bent inward to provide a small hole, and a fixed collar with a bolt hole is formed at the front end. a reaction ring having a size to abut against the rear end of the sleeve in the main body and having a threaded hole into which a bolt is screwed; a fixing bolt that can be inserted and screwed into a threaded hole in the reaction ring;

The fixing tool is inserted from the front side into a mounting hole in a wall or floor, and the bolt is tightened while the fixing collar is engaged around the mounting hole. As the bolts are tightened in this manner, the reaction ring gradually approaches the back side of the wall or floor, and this approach compresses the body. The body expands and bends outward due to this compression, and this bent portion becomes nearly flat, presses against the back surface of the wall or floor, and is fixed. The gas plug is attached to the fixed collar side fixed in this way.

[Embodiments and their functions] FIG. 1 is an exploded perspective view of a fixture according to the present invention, and 1 is a fixture body made of metal or plastic. This fixture main body 1 has a slit 5 parallel to the body 3, a fixing collar 2 having a hole 2'' and a bolt hole 2' at the front end of the body 3, and a fixing collar 2 having a hole 2'' and a bolt hole 2' in the middle part of the body 3. The rear end of the sleeve 3 is bent inward, and a small hole 3' is provided here.

6 is a reaction ring, and this reaction ring 6 is provided with a hole 6' and a screw hole 7. In addition, in the fixture main body 1, the outer diameter of the fixing collar 2 is larger than the diameter of the target mounting hole, and the dimensions of the body 3 and the reaction ring 6 are set so that they are slightly smaller than the diameter of the mounting hole. ing.

An example of the construction of the above-mentioned fixture will be explained next. First, as shown in FIG. 2, insert the bolt 8 into the bolt hole 2' of the fixing collar 2 of the fixture body 1, and then insert the tip of this bolt 8 into the screw hole of the reaction ring 6 through the small hole 3'. 7, insert it into the mounting hole 10 of the wall 9, and tighten the bolt 8 while pressing the fixing collar 2 against the wall 9 as shown in FIG. As the bolt 8 is tightened, the reaction ring 6 approaches the back side of the wall 9, and due to this approaching action, the body 3 expands outward at the knob 4 and bends, and eventually the fourth
As shown in the figure, it is pressed against the back side of the wall 9 in a nearly flat state and is fixed in the mounting hole 10 with the wall 9 sandwiched therebetween.

The gas plug 11 is attached in front of the fixed collar 2 to a gas pipe 12 extending through the hole 6' of the reaction ring 6, the body 3, and the hole 2'', as shown in FIG.

[Effects of the present invention] As described above, the present invention inserts the main body of the fixing device into the mounting hole of the wall or floor from the front side, applies the fixing collar to the wall or floor, and compresses the body by tightening the bolt. This body is opened outward on the back side of the wall or floor and then bent, and the bent part is then pressed against the back side of the wall or floor and fixed, so the fixing plate can be attached to the mounting hole as in the conventional case. It has the effect of greatly improving workability compared to the method of inserting it by hanging it from the back side with a string or the like.

Others according to this invention. Since the mounting hole is equally compressed from the front and back, the fixing force is not biased and there is also the effect of not damaging the wall or floor.
