Description

Technical Field

[0001] The utility model belongs to the technical field of seismic brackets, and particularly relates to a seismic bracket for wire ducts in electrical design. Background Art

[0002] A wire duct is an important device for regulating the layout, fixing, and management of wires such as cables, wires, and data lines. In electrical design, especially in areas prone to natural disasters such as earthquakes, the seismic design of wire ducts is very important. Using a seismic bracket to fix and install the wire duct can ensure that the wire duct will not shift or fall off during an earthquake, reduce the occurrence of secondary disasters, and reduce losses of personnel and property.

[0003] The existing wire ducts mainly consist of a U-shaped trough body and a trough cover that can be disassembled and assembled on the top of the U-shaped trough body. Wires are routed inside the U-shaped trough body during electrical design; the existing seismic brackets mainly consist of load-bearing members, bottom support members, top limit members, diagonal bracing members, connecting members, etc. When using the existing seismic brackets to fix and install the wire duct, the seismic brackets clamp and surround the wire duct from all four sides, making it inconvenient to operate when later opening the trough cover to maintain (add, replace, etc.) the wires inside the U-shaped trough body. Imagine that the seismic brackets clamp and surround the wire duct from all four sides. If you want to open the trough cover, you need to disassemble the top limit member of the seismic bracket above the trough cover. Since there are load-bearing members or diagonal bracing members of the seismic bracket on both sides in the length direction of the wire duct, even if you need to add or replace wires, due to the obstruction of the load-bearing members or diagonal bracing members on the side of the wire duct, the wires can only be threaded along the length direction of the wire duct, and cannot be directly disassembled and assembled from one side in the length direction of the wire duct, which causes inconvenience to construction operations. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a seismic bracket for wire ducts in electrical design. The members of the seismic bracket located on one side in the length direction of the wire duct can be disassembled and assembled, so as to facilitate the maintenance of the wires inside the wire duct from the side and make construction operations more convenient, so as to solve the problems raised in the above background art.

[0005] The utility model is realized through the following technical solutions:

[0006] A seismic bracket for wire ducts in electrical design includes an upper cross beam. There are two load-bearing members arranged symmetrically left and right above the upper cross beam, and the bottom end of the load-bearing member is fixedly connected to the upper cross beam, and its top end is provided with a U-shaped connecting member. The top end of the load-bearing member is bolted to the U-shaped connecting member, and the U-shaped connecting member can be anchored to the building structure by expansion anchor bolts;

[0007] Above the upper crossbeam, there are two symmetrically arranged diagonal bracing members on the left and right, and the two diagonal bracing members are respectively located outside the two U-shaped connecting members. At both ends of each diagonal bracing member, there are upper seismic connecting members and lower seismic connecting members. The top end of the diagonal bracing member is bolted to the upper seismic connecting member, and the upper seismic connecting member can be anchored to the building structure by expansion anchor bolts. The bottom end of the diagonal bracing member is bolted to the lower seismic connecting member, and the lower seismic connecting member is bolted to the upper crossbeam. When laying the wire duct in the electrical design, the above structure can fix the upper crossbeam under the building structure;

[0008] Below the upper crossbeam, there is a lower crossbeam for supporting the wire duct. At both ends of the lower crossbeam, there are two symmetrically arranged lateral connecting members on the left and right. The top end of one lateral connecting member is fixedly connected to the left end of the upper crossbeam by a plurality of bolts, and its bottom end is fixedly connected to the left end of the lower crossbeam by a plurality of bolts. The top end of the other lateral connecting member is fixedly connected to the right end of the upper crossbeam by a plurality of bolts, and its bottom end is fixedly connected to the right end of the lower crossbeam by a plurality of bolts. The lateral connecting members are bolted to the upper crossbeam and the lower crossbeam, which is convenient for disassembly and assembly. When laying the wire duct, a plurality of the above seismic supports are arranged at intervals along the length direction of the wire duct, and the wire duct is suspended and supported by the seismic supports. The wire duct is located between the upper crossbeam and the lower crossbeam, and the two lateral connecting members are respectively located on both sides of the length direction of the wire duct. When maintaining (adding or replacing, etc.) the cables inside the wire duct body, disassemble the plurality of lateral connecting members on one side of the length direction of the wire duct. Under the connection action of the lateral connecting members on the other side, the stability of the lower crossbeam can also be ensured, so that the lower crossbeam can support the wire duct. Therefore, the cover of the wire duct can be opened, and construction operations can be carried out from one side of the wire duct to add or replace the cables inside the duct body, which is convenient for construction operations.

[0009] Further defined, each of the diagonal bracing members includes a lateral diagonal bracing member and a longitudinal diagonal bracing member, and upper seismic connecting members and lower seismic connecting members are connected to both ends of the lateral diagonal bracing member and both ends of the longitudinal diagonal bracing member. The diagonal bracing members with the above structure can improve the stability of the upper crossbeam and enhance the overall seismic effect of the seismic support.

[0010] Further defined, the upper seismic connecting member is composed of a first connecting member and a second connecting member. The first connecting member has a U-shaped structure and can be anchored to the building structure by expansion anchor bolts. The second connecting member has an H-shaped structure. Its top end is bolted and hinged to the first connecting member, and its bottom end is bolted and hinged to the top end of the lateral diagonal bracing member or the top end of the longitudinal diagonal bracing member, which can flexibly adjust the installation angle according to the on-site conditions and design requirements.

[0011] Further defined, the lower seismic connecting member, the first connecting member, and the second connecting member are all made of steel, with high structural strength.

[0012] Further limitation: the upper cross beam, the lower cross beam, the lateral diagonal bracing members and the longitudinal diagonal bracing members are all made of channel steel or square steel tubes.

[0013] Further limitation: a plurality of slot holes are formed in the upper cross beam, the lower cross beam, the lateral diagonal bracing members and the longitudinal diagonal bracing members, which can help to reduce their weight.

[0014] Further limitation: each of the lateral connecting members includes a diamond plate and flanges integrally formed at both ends of the diamond plate, and the two flanges are respectively bolted to the upper cross beam and the lower cross beam, so that the length of the lower cross beam is less than that of the upper cross beam, which can reduce the space occupation.

[0015] Further limitation: two L-shaped limiting plates that are symmetric about the left and right are arranged on the top surface of the lower cross beam, and the L-shaped limiting plates are fixedly connected to the lower cross beam by bolts. The two L-shaped limiting plates can limit and fix the groove body of the wire duct from the left and right sides on the top surface of the lower cross beam to prevent the groove body from shaking left and right.

[0016] Further limitation: a limiting nut is welded on the top surface of the middle part of the upper cross beam, a limiting screw rod extending in the vertical direction is threadedly connected in the limiting nut, and the limiting screw rod penetrates through the upper cross beam. The bottom end of the limiting screw rod can abut against the top surface of the cover of the wire duct to prevent the cover of the wire duct from being easily opened. When maintaining the cables inside the groove body of the wire duct, the limiting screw rod can be rotated to move upward, so that the cover of the wire duct has an operating space for opening, thereby facilitating the opening of the cover of the wire duct.

[0017] Compared with the prior art, the utility model has the following beneficial effects:

[0018] During the wire duct layout in the electrical design process, the seismic support can be used to fixedly install the wire duct during the wire duct layout in the electrical design process, ensuring that the wire duct will not be displaced or fall off during an earthquake. Along the length direction of the wire duct, a plurality of seismic supports need to be arranged at intervals to fixedly install the wire duct on the building structure; when using this seismic support to fixedly install the wire duct, the wire duct is located between the upper cross beam and the lower cross beam, and the two lateral connecting members are respectively located on both sides of the length direction of the wire duct. When maintaining (adding or replacing, etc.) the cables inside the groove body of the wire duct, disassemble a plurality of lateral connecting members on one side of the length direction of the wire duct. Under the connection action of the lateral connecting members on the other side, the stability of the lower cross beam can also be ensured, so that the lower cross beam can support the wire duct. Since there are no load-bearing members or diagonal bracing members blocking on the side of the wire duct, there is no need to thread the cables through between the two lateral connecting members along the length direction of the wire duct. The cover of the wire duct can be opened, and construction operations can be carried out from one side of the wire duct to add or replace the cables in the groove body, which is convenient for construction operations, does not need to drag the cables inside the groove body, and is also convenient for cable arrangement, helping to speed up the construction progress.
