Description

Base plate of pipe clamp {BASE PLATE OF PIPE CLAMP}

The present invention relates to a base plate of a pipe clamp, and in particular, the outside is formed stepped into the mounting hole of the plate in which the mounting holes are drilled in a plurality of predetermined places, and the narrow end is bent by a press, so that tolerance with the fastening bolt The present invention relates to a base plate of a pipe clamp that inserts and welds the removed bush to prevent the body of the pipe clamp from being pushed and to prevent the bolts fastened to the inner circumference of the bush from being loosened.

The pipe clamp is used to firmly fix the pipe in a building or a machine. An embodiment of a general pipe clamp will be described in more detail with reference to FIGS. 1A to 1C.

In the pipe clamp, a bush 12 having a female threaded portion formed therein is formed at the center thereof, and the bush 12 formed with an outer circumference stepped into a plurality of mounting holes 15 formed in the plate 14 is pressed with a press to press the bush 12. ) And the base plate 10 in which the plate 14 is crimped, and a plurality of predetermined locations corresponding to the fastening holes 11 of the base plate 10 are fastening holes 11 and other fastening holes 22 concentric with each other. On the outer circumference of the fastening hole 22 corresponding to the bush 12 is formed a receiving groove 24 for receiving the bush 12, the semi-circular pipe fixing groove 26 on the opposite side of the base plate 10 The first body 20 formed, the second body 30 symmetrically formed with the first body 20, and the other fastening hole 42 concentric with the fastening hole 32 of the second body 30 Inserted into the formed top plate 40 and the plurality of fastening holes 11, 22, 32, 42 formed concentrically as described above. It is composed of a bolt 50.

Meanwhile, reference numeral 32 in the drawing is a fastening hole to which the bolt 50 is fastened, 34 is a receiving groove, and 36 is a fixing groove into which the pipe 60 is inserted.

According to the embodiment of the pipe clamp configured as described above, as shown in FIGS. 1A and 1B, the base plate 10 is welded to the wall surface 70 to which the pipe is to be fixed, and then the base plate 10 is mounted thereon. The pipe 12 is positioned in the fixing groove 26 of the first body 20 by positioning the first body 20 so that the bush 12 of the bush 12 is inserted into the receiving groove 24. 30 and the top plate 40 are sequentially positioned so that the plurality of fastening holes 11, 22, 32, 42 are concentric, and then these fastening holes 11, 22, 32, 42 The bolt 60 is fastened into the pipe 60 to fix the position.

However, in the conventional pipe clamp as described above, since the bush 12 is pressed against the plate 14 by a press as shown in FIGS. 1B and 1C, vibration generated in the transfer process. There is a problem that the bush 12 and the plate 14 are separated by the impact or impact, and when the bolt 50 is fastened to the fastening holes 11, 22, 32, 42 by an overload When the bush 12 rotates together with the bolt 50, the bolting work efficiency is lowered. Since there is a tolerance between the bolt 50 and the fastening hole 11, vibration and impact after the bolt 50 are fastened. There was a problem that the bolt 50 is released while flowing back.

An object of the present invention for solving the problems as described above is formed in the mounting hole of the plate perforated mounting holes in a plurality of predetermined places, the outside is formed stepwise and the narrow end is bent by the press to allow the tolerance with the fastening bolt The present invention provides a base plate of a pipe clamp, by inserting and welding a bush having been removed, so that the body of the pipe clamp is not pushed and the bolt fastened to the inner circumference of the bush is not loosened.

A feature of the present invention for achieving the above object is that the body 20 is formed on the base plate 80 is formed with a receiving groove 24 of a predetermined dimension at the end of the fastening hole 22 to which the bolt 50 is fastened In the pipe clamp for fixing the pipe 60, the base plate 80 is formed with a fastening hole 81 having a female threaded portion formed in the center and the middle of the outer circumference is formed stepwise, the end of the narrow portion 82 toward the inside The press 83 is formed by bending the bush 83 formed to be bent to remove the tolerance with the bolt 50 into the plurality of mounting holes 85 formed in the plate 84, and then press-welding the bush 83 to the plate 84. To tighten the fastening state and to tighten the fastening state of the bush 83 and the bolt (50).

Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

Figure 2a is a perspective view showing a base plate of the pipe clamp according to the invention, Figure 2b is a cross-sectional view showing an embodiment of a pipe clamp using a base plate according to the present invention, the same reference numerals as in Figures 1a to 1c. In order to avoid duplication of the same sign.

The base plate according to the present invention, in which the body 20 having the receiving groove 24 of the predetermined size is assembled at the end of the fastening hole 22 into which the bolt 50 is inserted, has a female screw portion as shown in FIGS. 2A and 2B. The formed fastening hole 81 is formed in the center, and the outer circumference is formed stepwise, and the narrow portion 82 is pressed inward to form a bush 83 formed to bend to remove the tolerance with the bolt 50. It is inserted into the plurality of mounting holes 85 formed in 84, and then crimped and welded.

In addition, in the embodiment of the pipe clamp using the base plate configured as described above, as shown in FIG. 2B, the base plate 80 is welded and mounted on the wall surface 70 to which the pipe 60 is to be fixed. The first body 20, the pipe 60, the second body 30 and the top plate 40 are sequentially positioned so that the fastening holes 81, 22, 32 and 42 are concentric. The bolt 60 is fastened into these fastening holes 81, 22, 32, and 42 to fix the pipe 60. At this time, since the narrow end of the bush 83 is bent inwardly and the tolerance with the bolt 50 is removed, the bolt 50 and the bush 83 are forcibly tightened so as not to be shaken by any vibration or shock thereafter. .

Therefore, since the base plate 80 according to the present invention is crimped and welded to the plate 84 and the bush 83, the bush 83 and the plate 84 are separated by vibration or the like generated during the transfer process. If the bolt 50 is fastened with the fastening holes 81, 22, 32, and 42, the bush 83 does not rotate like the bolt 50 even if an overload is applied. This is improved, and because the end of the bush 83 is formed to be bent inward to remove the tolerance with the bolt 50, the bolt 50 may flow due to vibration and shock after the bolt 50 is fastened. The bolt 50 is not loosened so that it does not occur.

According to the present invention configured as described above, because the plate and the bush is crimped and welded, the bush and the plate are not separated by vibration or shock generated during the transfer process, and when the bolt is fastened by the fastening hole, Even if it is caught, the bush does not rotate like a bolt, so the efficiency of bolting is improved, and the bolt and bush are forced to tighten because the end of the bush is bent inward to remove the tolerance. The bolt does not flow due to vibration and shock, and thus the bolt is prevented from being loosened, and thus, the pipe fixing state is not deteriorated.
