Description

  The present invention relates to a fixing structure of a pipe clamp that can securely fix a one-touch type clamp for holding a pipe to a support by a hammering machine.

  2. Description of the Related Art Conventionally, pipe clamps have been used to fix a pipe to a floor surface, a wall surface, or the like when performing pipe work.

For example, in the following Patent Document 1, as shown in FIG. 14 in the column of the prior art, a base 51 and a pair of support portions 53A and 53B formed continuously from both ends of the base 51 are provided. A pair of sandwiching piece pieces 54A and 54B each having a semi-cylindrical shape are movably provided at the distal ends of the support parts 53A and 53B. The pair of clamping part pieces 54A and 54B form a clamping part for clamping and fixing the pipe. A fitting convex portion 54a is formed on the outer peripheral side of the tip end portion of the one sandwiching piece 54A, and the fitting convex portion 54a is formed on the inner peripheral side of the tip end portion of the other sandwiching piece piece 54B. A pipe clamp 50 (hereinafter also referred to as a one-touch type pipe clamp) provided with a fitting concave portion 54b to be fitted to is disclosed. In pipe work, after the pipe clamp 50 is fixed in place with screws or the like, the pipe is inserted into the holding parts 54A and 54B, and the lower end portions of the holding part pieces 54A and 54B are inserted by the inserted pipe. By pushing down, the fitting convex portion 54a and the fitting concave portion 54b are automatically engaged with each other. The figure which showed the fitting state of the pipe is FIG. As is clear from the figure, after the holding piece pieces 54A and 54B are engaged with each other, the tip end portion of one holding piece piece 54A is pushed downward, or the tip end portion of the other holding piece piece 54B. The engagement is not released unless it is pushed upward.
JP-A-11-287360

  The one-touch type pipe clamp according to Patent Document 1 automatically engages the tip portions of the sandwiching piece pieces 54A and 54B by inserting the pipe into the sandwiching piece pieces 54A and 54B and then pressing down the pipe. It is excellent in workability in that it can be used.

  A number of the one-touch type pipe clamps are fixed to a support such as concrete, metal, wood, etc., but there is no particular problem when screwing with a screwdriver or the like, but in order to improve workability If a hammer is used, the fixation with the hammer will drive the hammer into the screw hole formed in the base 51. Therefore, if the hammer driving force is too high, In many cases, the stand 51 was damaged on the spot, or even when no damage was observed at the time of striking, the table 51 was broken by residual stress after a lapse of time. In addition, the workability is poor because it is necessary to force the pair of sandwiching pieces 54A and 54B to be forcibly expanded before each beating.

  Accordingly, a main object of the present invention is to provide a pipe clamp fixing structure that can be securely fixed to a support by a hammering machine without damaging the one-touch type clamp.

In order to solve the above-mentioned problem, the invention according to claim 1 is provided with a base and a substantially semi-cylindrical sandwiching piece movably provided on both sides of the base.

Next, a pipe is inserted between the sandwiching piece 11A and 11B, and the pipe 3 is pushed downward while pushing the lower end portion of the sandwiching piece 11A and 11B downward, thereby holding the sandwiching piece 11A. 11B, the fitting convex part 11a and the fitting concave part 11b are engaged, and the pipe 3 is fixed.

  In addition, although the pipe clamp 1 mentioned above illustrated what was conventionally provided in the Japanese market (brand name: Clic Switzerland EgLi, Fischer & Co. AG company (eguri, Fischer und. AG company), the present invention The present invention can be applied to so-called one-touch type pipe clamps that hold a pipe by engaging a fitting convex portion and a fitting concave portion of a pair of sandwiching piece pieces.

[Third embodiment]
As shown in FIGS. 10 and 11, the tacking attachment 4C according to the third embodiment is an improvement of the tacking attachment 4A according to the first embodiment in consideration of workability and driving accuracy. . As shown in FIG. 10, notches 45 and 45 for locking the tip of the injection port of the hammering machine 6 are provided on both side edges closer to the base end side in the tacking seat 42, respectively. To.

  There are several types of structures of the injection port 47 of the hammering machine 6, but the one made by HILT, which has the highest stake, has a U-shape with one side open as shown in FIG. A substantially U-shaped notch 47a is formed on the side surface of the injection port opposite to the opening side surface, and the tip of each of the ends has a corner projection on both sides of the substantially U-shaped notch 47a. It has a structure in which the portions 47b and 47b are formed. Therefore, in the tacking attachment 4C according to the third embodiment, the corner protrusions 47b and 47b at the tip of the ejection port are respectively locked to both side edges of the tacking seat 42 near the base end side. The notches 45, 45 are provided.

  Accordingly, as shown in FIG. 9, when driving the scissors with the scissor driving machine 6, the corner protrusions 47 b, 47 b at the front end of the scissor driving machine are provided with notches 45, It can be beaten in a state where it is locked to 45 and the tip of the injection port is fixed.

Further, in the so-called upward hammering operation for fixing the pipe clamp 1 to the upper surface of the frame or the frame, as shown in FIG. While engaging the protrusions 47b, 47b, the pipe clamp 1 can be held at the tip of the injection port, and the tip of the injection port 47 can be brought into contact with the ceiling surface or the like in this state to drive the scissors. For this reason, it is possible to easily perform the upward striking work that has conventionally been performed by supporting the pipe clamp 1 with one hand and holding the striking machine 6 with the other hand.
In addition, the structure which provides the notch parts 45 and 45 for latching the corner protrusions 47b and 47b of the hammering machine 6 in the tacking seat part 42 is the tacking attachment 4B which concerns on the said 2nd form example. It is possible to apply to the same way.
