Description

Bolt-integrated seismic hanger and its assembly method {BOLT INTEGRATED SEISMIC HANGER AND ASSEMBLING METHOD THEREOF}

The present invention relates to a bolt-integrated shockproof hanger and a method for assembling the same, and more specifically, to a bolt-integrated shockproof hanger and a method of assembling the same for minimizing various damages caused by collapse of the ceiling inside a building when an earthquake or an external force shaking the building occurs. About.

In general, when constructing a building, the ceiling panel finishing the indoor side of the ceiling slab is fastened with anchor bolts to an anchor buried in the ceiling slab, and structures such as embar and carrying for installing the ceiling panel are attached to the anchor bolts. A hanger for installation is fixed by a fixing member such as a nut.

In addition, a pipe for supplying living water is installed inside the wall of a building, and the process leading to the inside of the wall or the pipe drawn from the inside of the wall is usually fixed by a support means called a hanger.

In addition, in the case of electric cables that are bundled into bundles of several strands, they are guided to the power supply or the load side by means of a hanger.

These hangers are not absorbed and buffered even with small vibrations if the seismic design for earthquakes is not considered, and the anchor bolts and nuts are loosened by micro-vibration as they are transmitted to the pipes such as gas or boiler. Deformed or high risk.

In addition, as a ceiling panel, piping pipe, or electric wire falls along with the anchor structure, the risk of damaging property and human life increases.

Therefore, it is preferable that the hanger structure for installing the ceiling panel includes a seismic device.

Korean Patent No. 10-0858665 One-touch pin fastening device has been proposed as an example of a seismic device for protecting a hanger structure from vibration and impact.

In the one-touch pin fastening device, as the lifting operation pipe inserted into the slide hole of the hanger is fastened with the anchor bolt, an elastic member is placed on the upper surface of the anchor on the outer circumference of the lifting operation pipe. This is done by fixing the fixing nut fastened to the upper part to the lifting operation pipe through a riveting method.

In such a structure, it is practically impossible to fix the nut by riveting the upper end of the lifting operation pipe because it is necessary to adjust the position of the hanger through aerial work on the anchor bolt fixed to the anchor embedded in the ceiling slab. .

Therefore, since the installation work of the hanger structure is a work that requires the hanger to be suspended in a high position, it is required that the hanger, which is a key element of the work, be formed in a structure that is convenient to use so that the work can be performed as efficiently and easily as possible.

As an example of another structure, Korean Patent Laid-Open Publication No. 10-2010-002288 has been proposed for seismic and vibration-proof pipe hangers.
