{NON-STRUCTURED EARTHQUAKE-RESISTANT DEVICE FOR INSTALLING STUD BOLT}

The present invention relates to a non-structural earthquake-resistant device, and specifically, the upper end is fixed to the ceiling slab and the lower end is fixed to the electrical bolt, thereby reinforcing the electrical bolt, thereby reinforcing the earthquake resistance of the equipment that is a non-structural element of the electrical bolt, This relates to a non-structural seismic device for installing electric bolts that allows for simple seismic reinforcement by enabling installation in a position that does not interfere with the equipment even when equipment, which is a non-structural element, is already installed in the electric bolt.

Excluding structural elements such as pillars, foundations, beams, braces, sleeves, and structural walls, it refers to components such as architectural, mechanical, and electrical equipment and their fixtures and attachments that are permanently installed in the structure. In other words, non-structural elements of a building include all elements except structural members.

Architectural non-structural elements include exterior walls, partition walls, interior and exterior decoration members, ceilings, railings, awnings, chimneys, and stairs. Mechanical non-structural elements include ceiling-type air conditioners, mechanical equipment, boilers, water tanks, coolers, etc. Emergency generators, pumps, pipes, ducts, etc.

In general, these non-structural elements are not designed with earthquake resistance in mind after an analysis of the impact of earthquakes by relevant engineers, but are instead designed by architects, mechanical engineers who design piping or HVAC systems in buildings, electrical engineers, or interior designers. It is drawn by . And it is a common reality that the building in question is used without any professional design or supplementary measures by the owners or users after construction.

Meanwhile, non-structural elements such as various water supply and drainage pipes, lighting, and electrical facilities such as cable ducts are installed on the concrete ceilings of building parking lots, subway passages, and machine rooms. The facilities are usually computer systems embedded in the concrete ceiling. Methods such as fixing directly using bolts or fixing by fastening a semicircular band-type hanger with bolts are used.

Recently, a variety of earthquake-resistant devices have been developed to prevent structures from being affected when vibration occurs in buildings due to external factors such as earthquakes.

For example, Domestic Patent Publication No. 10-1981236 discloses a reinforcing member for electric bolts and an earthquake-resistant hanger device using the reinforcing member for electric bolts, and a seismic hanger device for cable trays titled No. 10-1879159.

The reinforcing member for the electric bolt and the earthquake-resistant hanger device to which the reinforcing member for the electric bolt is applied includes the electric bolt (10, 20) having threads (11, 21) formed on the outer peripheral surface as shown in FIG. 1; A reinforcing tube (300) that is open on both sides and in which the electric bolts (10, 20) are spaced apart (離隔); One of the two separated by cutting the cylindrical body, one side fastening body 400 having a screw groove 410 formed on the inner peripheral surface and a main fastener 420 having a fastening surface 421 on one side of the outer peripheral surface protruding; The remaining one of the two separated by cutting the cylindrical body, the other fastening body 500 having a screw groove 510 formed on the inner peripheral surface and a longitudinal fastener 520 having a fastening surface 521 on one side of the outer peripheral surface protruding; It consists of

As shown in FIG. 2, the seismic hanger device for the cable tray extends in the longitudinal direction and includes a plurality of support channels 24 supporting the cable tray 22, fixed to both ends of the support channels 24, and extending vertically upward. It is provided with a lower rod (26b), an upper rod (26a) fixed vertically to the vertical upper part of the lower rod (26b), and a seismic damper (30) provided between the upper rod and the lower rod (26b).

However, these conventional earthquake-resistant devices have a complicated work process because they require installing bolts vertically on the ceiling to install equipment, which is a non-structural element, and then installing the earthquake-resistant device and then installing the equipment. When adding a seismic device to a system, there is a problem in that the facility must be dismantled and then reinstalled after installing the seismic device.
