Description

{Pipe hanger for earthquake-proof}

More particularly, the present invention relates to a piping hanger for an internal combustion engine, and more particularly, to a piping hanger for an internal combustion engine, which is equipped with fixing means for fixing a lower end portion of an earthquake resilient member fixed at a lower end of a nut, And to prevent deformation of the fixed pipe by buffering the vibration when the vibration occurs due to an earthquake or an external shock through the earthquake-resistant elastic member, and to prevent the deformation of the fixed pipe. .

Generally, when installing various piping pipes such as a water pipe, a sewer pipe and an indoor pipe on a mounting surface such as a ceiling of a building, the supporting rods are fixed to the mounting surface at equal intervals, the pipe hangers are mounted on the lower ends of the respective supporting rods, The pipe is detained in the hanger and installed.

Figs. 1 and 2 show a conventional pipe hanger 1-3 (1-4) mounted on the lower end of a support rod when the pipe is installed.

The conventional pipe hanger 1-3 shown in Fig. 1 is a publicly known public utility model No. 20-1990-14681, a public utility model No. 20-1994-27123, a public utility model No. 20-1995-27946, Published Public Utility Model No. 20-1997-43463, Public Utility Model No. 20-1998-3991, Utility Model Registration No. 20-190184, Utility Model Registration No. 20-197233 (Patent Application No. 10-2005-109563).

In this case, a pair of semicircular bands 2 and 3 are formed, and mounting pieces 4 and 5 having mounting holes 4-1 and 5-1 are formed at the upper ends of the semicircular bands 2 and 3, And the mounting brackets 4 and 5 of the semicircular bands 2 and 3 are integrally formed with the lower ends of the support brackets 10 And the mounting pieces 11 formed with the mounting holes 11-1 are fastened by fastening means such as the bolts 12 and the nuts 12-1 respectively and are fastened to the upper surface of the support bracket 10, The conventional computer bolt 60 as shown in Fig.

The conventional pipe hanger 1 - 3 thus formed is attached to the mounting piece 4 (5) of the semicircular band 2 (3) and the mounting piece 11 of the supporting bracket 10 The nut 12-1 is released from the bolt 12 to separate the semicircular band 3 on one side and the pipe is pulled in between the fixed semicircular band 2 and the free semicircular band 2, The semicircular bands 3 separated by the hand are supported by the fastening pieces 9 while being prevented from being separated by the hand and the mounting holes 5-1 punched in the mounting pieces 5 are inserted into the bolts 12, The nut 12-1 must be screwed to the tip end of the bolt 12 projecting outwardly of the main body 5 so that the installation process is very difficult and the semicircular band 2 is formed in a completely semi- Since the pipeline is located on the ship, it is necessary to fasten the semicircular band (3) while supporting the pipe pulled in the inner side so as not to fall, I can not have a problem.

Further, the bolts 12 and the nuts 12-1 screwed to the mounting pieces 4, 5, and 11 are also loosened by vibration, and the gripping force of the pipes is deteriorated.

Referring to FIG. 2, there is shown another conventional pipe hanger 1-4, which is disclosed in Korean Utility Model Registration No. 20-184219 and Utility Model Registration No. 20-414911.

The upper half band 40 and the lower half half band 50 are formed into a semi-circular shape and can be divided and separated.

An upper end portion of the lower band 40 is integrally formed with a fastening hole 43 at one end thereof and an extension portion 41 formed at the other end thereof with the hooking protrusion 42 protruding outwardly. 50 are formed at one end thereof with a fastening piece 59 which can be engaged with and detached from the fastening hole 43 and at the other end thereof with a vertical hole 51 and a horizontal hole 51, And a gap-type flange 51 formed with spring retaining grooves 51-1 at both ends of the upper surface thereof are integrally formed.

The catching piece 54 is provided in the lower side of the cap-shaped flange 51 to detach the catching piece 42 of the upper band 40 inserted (coupled) into the vertical insertion hole 52, A spring piece 56-1 and a loading groove 55 are formed at the front end and the rear end respectively and spring retaining grooves 54-1 and supporting protrusions 57 are formed on the front and rear of both ends, respectively, And the detent piece 54 can engage / disengage the annular coil spring 58 from the spring catch grooves 51-1 and 54-1.

However, when the pipe for piping is installed, the lower semicircular band 50 must be separated from the upper band 40, and the lower half semicircular band 50 is connected to the bottom of the pipe while the fastening piece 59 is fastened to the fastening hole The hooking protrusion 52 must be inserted into the vertical insertion hole 52 and the capping flange 51 of the lower semicircular band 50 should be inserted upward and the hooking protrusion 52 should be inserted into the vertical insertion hole 52. At the lower side of the capping flange 51, 54 are engaged with each other so that the hooking protrusion 42 inserted into the loading groove 55 is caught by the bottom of the transfer piece 54 and the insertion piece 56 at the tip end is inserted into the horizontal insertion hole 53, The protrusions 57 are projected to both sides of the cap-like flange 51.

Since the annular coil spring 58 must be attached to the outer side of the cap-shaped flange 51 and the detent piece 54 that are connected to each other, the installation process is very complicated, , The installation time is much consumed and the work efficiency is low. In addition, since the detent piece 54 and the annular coil spring 58 are separated, there is a problem that the pipe can not be installed if it is lost.

Particularly, in the conventional pipe hangers 1-3 (1-3) as described above, the support bracket 10 or the nut bundle 13 (44) coupled to the upper surface of the upper band 40 rotates freely So that it is shaken and rotated by an external impact, so that the engagement state of the bolt 60 is gradually released and the bearing force is weakened.

The nut bundle 13 mounted on the upper surface of the support bracket 10 has a flange formed at the lower end of the support pipe inserted from the lower side to the upper side of the upper surface, When the impact is applied to the outside or when vibration occurs due to an earthquake or the like, the vibration can not be attenuated (vibration damped), so that the bolt 60 and the support bracket 1 supporting the heavy pipe can not be damped, There is a problem that deformation occurs between the pipe and the pipe, and even if the impact is strong, the pipe is not only twisted but also can not be eliminated.

Therefore, it is possible to prevent the deformation of the fixed pipe by buffering the vibration when the vibration occurs due to the earthquake or the external impact through the vibration resilient member, and to prevent the deformation and the deformation of the vibration resilient member from being stably prevented. The research and development of a piping hanger for a piping pipe is required.
