Description

Technical Field

[0001] The utility model relates to a support device for cables at a construction site, belonging to the technical field of building construction. Background Art

[0002] During foundation construction, cables (power cables or communication cables) need to be temporarily erected in the construction site. To avoid damage to the cables caused by contact and friction with sharp debris such as gravel and nails in the foundation, the cables need to be supported at intervals by a support frame on the temporarily hardened road on the side of the guardrail.

[0003] For the existing support frame for supporting cables at intervals, see Chinese Patent Publication No. CN213027237U. Although there is a U-shaped bracket for supporting cables on the tripod, the U-shaped bracket is connected to the top of the tripod. In order to flexibly adjust the support for the cables, the bottom of the tripod is not fixed. For a relatively long cable, when it sways, the inertial force is relatively large, and there is a problem that the swaying cable is likely to cause the U-shaped bracket on the top of the tripod to tip over. Summary of the Utility Model

[0004] To solve the above technical problems, the utility model provides a support device for cables at a construction site.

[0005] The utility model is achieved through the following technical solutions.

[0006] A support device for cables at a construction site provided by the utility model includes:

[0007] A U-shaped support;

[0008] A support member, which is fixedly installed at the bottom of the U-shaped support;

[0009] A corner bracket for fixedly installing the bottom of the support member, and the support member is fixedly installed at the lower part of the corner bracket.

[0010] The support member is telescopic, and the support member is a hydraulic telescopic member or a threaded rod telescopic member.

[0011] The corner bracket includes a support angle and a mounting plate installed at the lower part of the support angle. The support member for supporting the U-shaped support is fixedly installed on the mounting plate at the lower part of the corner bracket.

[0012] There are four support angles. The support angles are fixedly connected from the outside to the inside and form a corner bracket at the four corners of the mounting plate. The mounting plate is fixedly installed at the lower part of the support angles of the corner bracket.

[0013] The support angle is a cone with a smaller top and a larger bottom. The support angle of the cone is recessed downward from the top surface to form a receiving space for receiving water or sand.

[0014] There is a corner plate at the bottom of the support angle. The corner plate is provided with mounting through holes for bolts to penetrate and be fixed on the temporarily hardened road.

[0015] The mounting plate is provided with a hanging through hole, in which a hook A is hung. An elastic column is fixed to the hook A, and a hook B is fixed to the elastic column. The hook B is hung on the guardrail.

[0016] The elastic column is made of elastic rubber, and there are two elastic columns arranged in parallel at intervals.

[0017] The beneficial effect of the utility model is that when the cable shakes in the U-shaped bracket and generates a large inertial force, since the U-shaped bracket is fixedly installed on the mounting plate at the lower part of the corner bracket through the support member, the shaking inertial force is not easy to cause the mounting plate at the lower part of the corner bracket to tip over relative to the support angle, solving the problem that the shaking cable is prone to tip over with the U-shaped bracket at the top of the tripod.

Detailed Embodiment

[0021] The technical solution of the utility model will be further described below, but the scope of protection claimed is not limited thereto.

[0022] As Figures 1 to 2 shown.

[0023] A support device for cables at a construction site according to the present application includes:

[0024] A U-shaped bracket 1 for supporting the cable 11, and a telescopic support member 2 is installed at the bottom of the U-shaped bracket 1. The support member 2 can be composed of a hydraulic telescopic member or a threaded rod telescopic member, etc. The U-shaped bracket 1 for supporting the cable 11 is adjusted up and down by the telescoping of the support member 2.

[0025] It further includes a corner bracket 3 for fixedly installing the bottom of the support member 2. The corner bracket 3 includes three or four support angles 31 and a mounting plate 32 installed at the lower part of the support angles 31. The support angles 31 are fixedly connected to the four corners of the mounting plate 32 and inclined from the outside to the inside to form the corner bracket 3. The mounting plate 32 is installed at the lower part of the support angles 31. The support member 2 for supporting the U-shaped bracket 1 is fixedly installed on the mounting plate 32 at the lower part of the corner bracket 3 by welding or a threaded pair, reducing the height of the shaking inertial force of the cable 11 relative to the contact with the temporary hardened road 4 of the corner plate 34.

[0026] When the cable 11 shakes on the U-shaped support 1 and generates a large inertial force, since the U-shaped support 1 is fixedly installed on the mounting plate 32 at the lower part of the angle bracket 3 through the support member 2, the shaking inertial force is not easily overturned relative to the support angle 31 on the mounting plate 32 at the lower part of the angle bracket 3, solving the problem that the shaking cable is prone to rollover with the U-shaped bracket at the top of the tripod.

[0027] The support angle 31 is a cone with a smaller upper part and a larger lower part. The support angle 31 of the cone is recessed downward from the top surface to form a receiving space 33 for receiving water or sand; when water or sand is placed into the receiving space 33, since the support angle 31 is a cone with a smaller upper part and a larger lower part, the water or sand can further pull down the center of gravity of the angle bracket 3, ensuring that the U-shaped support 1 at the upper part of the angle bracket 3 is more difficult to roll over when supporting the cable 11.

[0028] There is an angle plate 34 at the bottom of the support angle 31, and the angle plate 34 is provided with mounting through holes for bolts to penetrate and be fixed on the temporary hardened road 4.

[0029] The mounting plate 32 is provided with a hanging through hole 35. A hook A 36 is hooked in the hanging through hole 35. The hook A 36 is welded and wrapped to fix an elastic column 37. The elastic column 37 is welded and wrapped to fix a hook B 38. The hook B 38 is hooked on the guardrail 12. The elastic column 37 is composed of elastic rubber, and the elastic columns 37 are two parallel and spaced apart. When the cable 11 shakes with the U-shaped support 1, after the shaking inertial force is transmitted to the mounting plate 32 through the support member 2, the elastic column 37 elastically deforms to generate an elastic damping force to offset the shaking, further improving the stability of the angle bracket 3 in supporting the cable 11 on the U-shaped support 1.

[0030] A cable construction and laying process at the construction site of the present application includes the following construction processes:

[0031] On the side of the foundation 13, a temporary hardened road 4 is formed by pouring and curing concrete. A guardrail 12 in an erected state is fixed on the side of the temporary hardened road 4 close to the inner side of the foundation 13. Then, on the temporary hardened road 4 on the side of the guardrail 12, the cable 11 is supported by a cable support at the construction site. The elastic column 37 is correspondingly hooked on the mounting plate 32 and the guardrail 12 through the hook A 36 and the hook B 38, realizing the stable support of the cable 11 on the cable support at the construction site to avoid rollover.
