Description

Seismic Coupler of Thread Bolt for Computer Bolt

The present invention relates to a structure for preventing a structure such as a cable tray, a cable duct, a lighting device, a water supply pipe, a fire water pipe, a fan, etc. from being adversely affected by external factors such as an earthquake, And more particularly to an earthquake-resistant coupler.

Generally, concrete structures such as parking lots, subway passageways and machine rooms of large buildings are equipped with various types of structures including various kinds of water supply, drainage piping, lighting, and electric facilities such as cable ducts.

These structures are usually fixed by using anchor bolts buried in a concrete ceiling, or by clamping a semicircular band hanger with bolts.

In order to fix various pipes or heavy objects on the concrete ceiling, the band hanger is held at a predetermined interval on the insert plate embedded in the ceiling, and then the pipe or heavy material is horizontally mounted. The connection part of the pipe is broken or the heavy object falls to the ground and causes an accident.

Recently, a variety of vibration absorbing devices have been developed to prevent structures from being affected by external factors such as earthquakes when vibrations occur in buildings.

This type of vibration absorption usually affects the facility by connecting the fixed shaft to the insert plate installed on the concrete ceiling of the building and then absorbing the external vibration through the seismic fastener or spring between the supporting means fastened to the fixed shaft. I do not give.

However, in the case of such facilities, since the strength for maintaining the weight is required to be calculated according to the purpose or type, it is necessary to extinguish the spring, so that the installation work is rather complicated. In actual construction, depending on the rough sense, There is a problem that the function can not be performed at the time of occurrence of the problem.

In addition, the seismic fastener and the spring are incomplete, and the seismic cable tray system incurs excessive fabrication cost and complicated installation process, thereby increasing the cost.

Regarding the earthquake-proofing technique for such a structure, the technique disclosed in the Japanese Patent Application Laid-Open Publication No. 2001-0030224 is constructed by simply installing an anti-vibration spring along the longitudinal direction of the vertical fixing table in order to absorb vibration, It is difficult to suppress the generated vibration and the fastening member for supporting the seismic spring can be easily detached from the position fixed to the vertical fixing table by the vibration.

Therefore, when exposed to strong vibration or long-time vibration, the cable tray on which the upper and lower fixing plates are placed is separated, so that the cable tray can not be stably maintained.

In addition, although the technique disclosed in Japanese Laid-Open Patent Publication No. 2016-0044445 absorbs up-and-down vibration generated due to the impact of a seismic wave to prevent breakage and deformation of electric wires installed in the electric trays, And it is vulnerable to a shock acting in the horizontal direction.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings, but the specific structures and functions of the present invention are not limited to the embodiments described in the present specification.

First, as a preferred example to which the present invention is applied, some configurations disclosed in Japanese Patent No. 1436333 will be described, and then the configuration and operation effects of the present invention will be described below.

1 is a schematic view showing an example of use of a seismic cable tray system, which includes a cable tray CT, support members a and b, and an earthquake-proof apparatus c. The cable tray supporting members a and b can be attached to the cable tray support members a and b such that the cable tray CT is fixed to the transverse member a, and a pair of vertical members (b) capable of hanging the ceiling (a) from the ceiling.

A pair of seismic equipments c installed on both side edges of the transverse member a can be constructed so as to connect the transverse member a and the ceiling while forming a certain angle with the vertical member b.

The cable tray CT can support the cable tray support members a and b so as to absorb vibrations in various directions, so that the earthquake-proof apparatus c having such a structure can support the cable tray support members a and b, / RTI >

In addition, since the seismic resistance device c supports the cable tray CT while reinforcing the cable tray support member b, the cable tray CT is prevented from a secondary danger due to the breakage of the cable tray support members a and b Can be protected.

As shown in Figures 2 to 4, the seismic cable tray system is additionally installed in cable tray 300 and cable tray support member 100 and cable tray support member, And a cable tray seismic device 200 constituting a set.

The earthquake-proof apparatus 200 can be used by being mounted on the cable tray support member 100. [ The cable tray supporting member 100 includes a transverse member 110 to which the cable tray 300 is fixed and a pair of vertical members 120 to which the transverse member can be suspended from the ceiling.

Although the seismic resistance device 200 is shown as being connected to the left end of the transverse member 110, the seismic isolation device 200 may be disposed on one side or both sides of the opposite ends.

The earthquake-proof apparatus 200 includes a first hinge unit 210, a connection unit 220 and a second hinge unit 230. The earthquake-proof apparatus 200 includes a pair of support members 100 and a ceiling As shown in FIG.

The first hinge unit 210 includes a pair of hinge members 211 rotatably coupled to each other by a hinge shaft 212 so as to be rotatably coupled to the horizontal member 110.

The first hinge part 210 may be mounted to protrude from upper surfaces of both side edges of the cross member 110. The hinge member 211 located at one side of the first hinge unit 210 is fixed to the transverse member 110 by the fixing members 222 and 223 and the hinge member 211 located at the other side is fixed to the fastening member 221 The connection part 220 can be coupled to the connecting part 220.

Accordingly, the first hinge unit 210 can elastically support the transverse member 110 and the connection unit 220 so that the connection unit 220 can rotate with respect to the transverse member 110 when vibration occurs.

The connection unit 220 is rotatably coupled to the transverse member 110 so as to be inclined at a predetermined angle with the vertical member 120 through the first hinge unit 210. The connection unit 220 has a predetermined length to connect the first hinge unit 210 and the second hinge unit 230, which are spaced apart from each other. One side of the second hinge part 230 is rotatably coupled to the connection part 220, and the other side is fixed to the ceiling.

The second hinge portion 230 may be installed on the ceiling at a position spaced apart from the outside of the vertical member. One side of the second hinge part 230 is rotatably coupled to the connection part 220, and the other side is fixed to the ceiling. The second hinge portion 230 may be installed on the ceiling at a position spaced apart from the outside of the vertical member.

The earthquake-proof apparatus 200 may be mounted on at least one edge of the lateral member 110a. Figures 2 and 3 illustrate an embodiment in which three are mounted. For example, a plurality of the seismic equipments 200 may be arranged in a direction in which the hinge axis is arranged in a direction parallel to the transverse member and one in the direction in which the hinge axis intersects the transverse member.

When a plurality of earthquake-proof devices 200 are installed on one side of the horizontal member 110a such that the hinge axes are in different directions, the cable tray supporting member 100 can be more stably supported .

Such an earthquake-proof device for a cable tray support member has the advantage of protecting the cable tray from an earthquake or a strong impact because it elastically supports the cable tray support member to absorb vibration in various directions. However, The workability is greatly reduced due to the various structures for the product, and the cost of the product is increased because the product price and the construction period are considerably long.

5 to 10C are views for explaining an earthquake-resistant coupler for a computer bolt according to the present invention.
