BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pipe pressing part, and more particularly to a pressing part for fixing a pipe in a groove of a wall surface using a lightweight concrete building material.

[0002]

2. Description of the Related Art In a structure using a lightweight concrete building material containing air bubbles as a wall material 1 as shown in FIG. 8, a groove 2 is formed in the wall material 1, and a pipe A for electricity, gas, etc. is formed in the groove 2. After fitting, the groove 2 is filled with mortar or the like to form a smooth wall surface, and wallpaper is attached to the wall surface for finishing.

By the way, when the pipe A to be embedded in the groove 2 is bent or warped, that portion becomes a portion a protruding from the wall surface as shown in FIGS. 8 and 9, and this protruding state is maintained. When the groove 2 is filled with mortar or the like, a partial bulge is generated on the wall surface, and the finish of the wall surface becomes unreadable. Therefore, the protruding portion a due to bending or warping of the pipe A is pressed before being embedded by mortar or the like. It is necessary to make it fit and fit in the groove 2.

Conventionally, the protruding portion a of the pipe A is formed in the groove 2
As shown in FIG. 10, the means for pressing the nail 3 into the inside and driving it into the groove 2 is such that the nail 3 is obliquely driven into the wall surface material 1 so as to come into contact with the outer surface of the protruding portion a of the pipe A fitted in the groove 2. In 3, the protruding portion of the pipe A was pushed in and held.

[0005]

However, the means for driving the nail 3 obliquely to hold down the pipe A is not only difficult to work, but also when the wall material 1 is thin, it may be struck by the vibration or impact of the nail. There is a problem that cracks may occur in the wall surface material 1 and the pressed state may not be obtained.

Therefore, in order to solve the above-mentioned problems, the present invention has an object to provide a pipe pressing component which can easily press down the pipe and which does not damage the wall material.

[0007]

SUMMARY OF THE INVENTION In order to solve the above problems, the present invention proposes a metal plate having a long piece and a short piece.
A press fitting is formed by bending it in a letter shape, punched out with a part left on the long piece to provide an engaging piece, and the tip of this engaging piece is bent in the opposite direction to the short piece It was done.

[0008]

[Function] With the pipe housed in the groove of the wall material, insert the long piece into the gap between the pipe and the groove of the protruding part of the pipe,
When the short piece comes into contact with the pipe and pushes it into the pipe, the tip of the engagement piece provided on the long piece bites into the inner wall surface of the groove to prevent the pipe from coming off, and the pushing of the pipe is maintained.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 1 to 7 of the accompanying drawings.

In the first embodiment shown in FIGS. 1 to 4, the pipe pressing component 11 is an L-shaped pressing metal member in which a relatively thin strip-shaped metal plate is bent at right angles to the long piece 12 and the short piece 13. 14 is formed, and the long piece 12 has an engagement piece 1 for retaining.
It has a structure in which 5 is punched out.

The long piece 12 is a pipe A to be fixed.
The length of the short piece 13 is equal to or slightly shorter than the outer diameter of the pipe A, and the short piece 13 is also set to have a length slightly shorter than the radius of the pipe A.

When the length of the short piece 13 is set as described above, when the short piece 13 pushes the pipe A, it pushes a position deviated from the center line of the pipe A in the front-rear direction. In addition, there is an advantage that the plate thickness of the short piece 13 does not protrude, and even when the groove 2 is shallow, it is possible to eliminate the generation of protrusions on the surface of the wall material 1.

The engaging piece 15 provided on the long piece 12 is punched out so that the tip side of the long piece 12 is left and the short piece 13 side is V-shaped, and the punched part is directed to the protruding side of the short piece 13. It is formed so as to be curved so as to form an arcuate bulging portion 16 that protrudes, and a sharpened tip 17 is bent in a direction opposite to the short piece 2.

The first embodiment of the present invention has the above-mentioned construction, and in order to press the protruding portion of the pipe A fitted in the groove 2 of the wall member 1, the protruding portion of the pipe A is The long piece 12 of the press fitting 14 is inserted into the gap between the groove 2 and the inner wall surface from the tip by pushing with a finger or the like.

As the long piece 12 enters the gap,
The bulging portion 16 of the engaging piece 15 contacts the pipe A,
5 is pushed out so as to project in the direction opposite to the short piece 13, its tip sticks to the inner wall surface, and the short piece 13 is in contact with the pipe A as shown in FIG. Push into.

The protruding portion of the pipe A tries to return to the protruding direction by the restoring force, but when the holding metal fitting 14 is pushed back in the pulling-out direction, the tip 17 of the engaging piece 15 is strongly pushed against the inner wall surface of the groove 2. Bite into it, and it will be in the retaining state.

Therefore, the protruding portion of the pipe A is the groove 2
It will be pushed into the interior, and the groove 2 will be filled with mortar to form a smooth wall surface, so that the wallpaper finishes without any problems.

The use example shown in FIG. 4 is a case where the width of the groove 2 is wide, and the metal fittings 14, 14 are inserted into the gaps formed on both sides of the pipe A and the groove 2 to press the pipe A from both sides. It is fixed.

Next, in the second embodiment shown in FIGS. 5 to 7, the engagement piece 15a provided by punching out the long piece 12 is provided with the short piece 1.
3 has a structure in which it is projected in an arc shape to the surface opposite to the projection direction of 3, and the sharp tip 17a is extended as it is to face the opposite side of the short piece 13.

The second embodiment has the above-mentioned structure, and the long piece 12 is inserted into the gap between the pipe A and the groove 2 from the tip like the first embodiment described above.

The long piece 12 advances in contact with the pipe A,
The engaging piece 15a advances while rubbing against the inner wall surface so that the tip of the engaging piece 15a is slightly returned by the elasticity of the thin metal plate. Push in.

After pushing in as described above, the pipe A has the groove 2
If it tries to stick out from, the engagement piece 15a will bite into the inner wall surface and prevent the pipe A from sticking out.

[0023]

[Effect] As described above, according to the present invention, by simply inserting the long piece of the holding metal fitting into the gap between the pipe and the groove that fits in the groove of the wall material and pushing the pipe with the short piece, the pushed part of the pipe is put into the groove. Since the pipe can be fixed easily and efficiently, and the engaging piece provided on the long piece engages the wall material to prevent the pipe from coming off, the wall material contains lightweight concrete building material. However, the pipe can be fixed without damaging the wall material.
