Hanger Clamp For Pipe{Hanger Clamp For Pipe}

The present invention relates to a clamp for a pipe hanger, and in particular, to a clamp for a pipe hanger having an improved structure to install a pipe by being fastened in a simple engaging manner without a fastening means such as a separate bolt.

In general, a clamp is fastened to a bolt fixed to the ceiling of a building or factory to transport drainage, water supply, or liquid material, and the pipe is installed by connecting the pipe to the clamp.

The pipe hanger clamp for this is, for example, in Korean Patent Publication No. 10-0758182 (registration date September 6, 2007), in a pipe hanger clamp in which a mounting part and a fastening part rotate around a hinge, A "c"-type fastening piece to which the connecting nut is mounted is formed, and a square fixing hole is formed on one side of this "c"-type fastening piece, and the rectangular fixing part formed under the head of the fastening bolt is combined, and it is stopped on the fastening bolt. There is disclosed a pipe hanger clamp in which a clamping bolt is held in a fixing hole of a "c"-type fastening piece by forcibly fitting the ball.

However, the hanger clamp having the above structure has a problem in that the construction period is delayed by the bolting operation as the free end of the clamp is fastened and fixed with a tightening bolt.

In order to solve this problem, in Korean Utility Model Publication No. 20-0440987 (registration date July 08, 2008), a computerized bolt coupling groove was formed along the lengthwise direction of the bottom of the clamping table, and computerized on both sides of the fixture. A one-touch pipe clamp has been proposed that extends the range of use by forming a channel coupling blade in a direction perpendicular to the bolt coupling groove so that it can be fixedly installed not only on a wall or ceiling, but also on a computer bolt and a C-type channel.

However, the pipe clamp for the registration room described above has an arc-shaped first support part at both ends of the fixture and the first and second flexible parts formed at the ends of the second support part, resulting in increased material cost and difficulty in processing. In addition to the problem of causing an increase, there is a problem in safety because the bites of the first and second flexible portions can be released when an impact is applied to the clamp.

As another example, in Public Utility Model Publication No. 20-2010-0003338 (published on March 26, 2010), an upper clamping member is fixed to an anchor bolt of a ceiling through an anchor bolt hole, and the lower side of the upper clamping member In the known pipe hanger clamp structure configured to fix the pipe for piping to the ceiling by coupling the lower clamping member to the upper clamping member, the upper clamping member is provided with a latch at the lower left end of the upper clamping member, and a hook hole is installed at the lower right of the upper clamping member, The lower clamping member has a clamping structure for a pipe hanger, characterized in that a hook-receiving mold having an entrance and a guide hole at its left upper end is installed so as to correspond to the hook, and a hook at its right upper end corresponds to the hook hole. Was proposed.

However, the clamp structure of the above-described public utility model publication is installed by hooking the lower left end of the upper clamping member to the lower right end of the hook hole, and then in close contact with the inner circumferential surface of the left side of the upper clamping member. In a state where the heavy pipe is placed on the concave shape of the lower clamping member by moving it downward from the state, the work of moving the clamping member of the upper clamping member through the entrance and moving to the inside of the clamping clamp receiving tube through the guide hole to fasten the lower clamping member. It is difficult to do, and accordingly, there is a problem that the pipe work time is delayed.
