Description

Technical Field

[0001] This utility model relates to the field of building structure construction technology, and in particular to a height-adjustable cable bracket. Background Technology

[0002] The conventional method for cable supports in cable trenches is to pre-embed angle steel in the sidewall of the cable trench or fix the angle steel to the sidewall of the cable trench using expansion bolts. The first method has the disadvantage that the position of the angle steel cannot be determined after pre-embedding, which is not conducive to later adjustment. The second method, using expansion bolts, is prone to causing cracks in the sidewall of the cable trench, which poses a risk of leakage. Moreover, if the height of the cable support needs to be adjusted later, the original support needs to be removed, new holes need to be drilled, and expansion bolts need to be used to fix it again, which is not conducive to preventing leakage in the cable trench.

[0021] like Figures 1-6 As shown, this utility model discloses a height-adjustable cable bracket, which includes a fixing device 1, a connecting device 2, and a sliding adjustment device 3. The fixing device 1 is cast in a preset position, there are several connecting devices 2, and all of the several connecting devices 2 are connected to the fixing device 1. The sliding adjustment device 3 is connected to the connecting devices 2.

[0022] The fixing device 1 includes a cable trench 11 and a pre-embedded groove 12. The cable trench 11 is made of U-shaped semi-enclosed cast-in-place reinforced concrete, and the pre-embedded groove 12 is made of U-shaped channel steel. The closed end of the pre-embedded groove 12 is located inside the U-shaped semi-enclosed structure of the cable trench 11 and is fixed inside the cable trench 11 by reinforced concrete. The open end is located outside the cable trench 11. The height of the pre-embedded groove 12 is the same as the height of the cable trench 11.

[0023] The two channel steels extending from the cable trench 11 of the pre-embedded groove 12 are provided with a number of positioning holes 121. The positioning holes on the two channel steels are arranged opposite each other. The number of positioning holes 121 on each channel steel is divided into two rows. The two rows of positioning holes 121 are arranged side by side on the pre-embedded groove 12. The two positioning holes 121 arranged side by side on each channel steel and the two positioning holes 121 on the other channel steel that are at the same horizontal plane as the two positioning holes 121 form a group.

[0024] The connecting device 2 is connected to the pre-embedded groove 12 through a set of positioning holes 121 using a fixing screw 4 and a first adjusting nut 5. The fixing screw 4 is a threaded cylindrical rod, and the first adjusting nut 5 is an internally threaded annular nut.

[0025] The connecting device 2 includes a first angle steel 21 and a second angle steel 22. The first angle steel 21 and the second angle steel 22 are of the same specifications and are welded diagonally. Both the first angle steel 21 and the second angle steel 22 are "L" shaped structures. The first angle steel 21 and the second angle steel 22 are at right angles, and the length of the second angle steel 22 is longer than that of the first angle steel 21.

[0026] The first angle steel 21 is located inside the pre-embedded groove 12 and is connected to one closed end of the U-shaped channel steel. The second angle steel 22 has a through hole 221 on one side of its "L"-shaped structure. The through hole 221 is located between a set of positioning holes 121. The second angle steel 22 is connected to the positioning hole 121 through the through hole 221 using a fixing screw 4 and a first adjusting nut 5, thus connecting the connecting device 2 and the fixing device 1. The other side of the second angle steel 22 has a sliding groove 222.

[0027] There are several sliding adjustment devices 3, all of which are connected to the sliding groove 222. Each device includes a sliding block 31 and a second adjusting nut 32. The sliding block 31 includes a first cylinder 311 and a second cylinder 312. The second cylinder 312 is connected to the lower end of the first cylinder 311. The first cylinder 311 is located at the upper end of the sliding groove 222. The second cylinder 312 passes through the sliding groove 222 and is located on the other side of the sliding groove 222. The second adjusting nut 32 is connected to the second cylinder 312.

[0028] The first cylinder 311 is a hollow cylindrical structure, and the outer surface of the second cylinder 312 is provided with a bolt structure 313. The second adjusting nut 32 fixes the sliding block 31 to the sliding groove 222 through the bolt structure 313.

[0029] During the construction of cable trench 11, the pre-embedded groove 12 is pre-embedded in the inner wall of cable trench 11 to form a through channel. After demolding, the connecting device 2 is fixed to the pre-embedded groove 12 at the required height using the fixing screw 4 and the first adjusting nut 5, and the cable can be installed. If it is necessary to adjust or increase the height and number of connecting devices 2, it is only necessary to unscrew the first adjusting nut 5 for adjustment. When adding connecting devices 2, they can be added directly in the empty space. The sliding block 31 on the connecting device 2 can be adjusted along the sliding groove 222 to divide the cable on the same cable bracket by adjusting the cable placement area.

[0030] The sliding block 31 slides along the sliding groove 222 to adjust the bracket spacing. The lower part of the sliding block 31 is the second adjusting nut 32. By tightening the second adjusting nut 32, the sliding block 31 can be secured. After loosening the second adjusting nut 32, the position of the sliding block 31 can be adjusted to adjust the spacing of the cable placement area. Multiple sliding blocks 31 can also be added to divide areas of different sizes.

[0031] Therefore, the present invention provides a height-adjustable cable bracket with the above-mentioned structure. It has a simple structure and can adjust the height of the cable bracket. At the same time, it fixes the pre-embedded groove in the cable trench, which solves the problem of needing to remove the original bracket, re-drill holes and re-fix it with expansion screws. Thus, it solves the problem of cable trench leakage. It is easy to adjust or add cable brackets at any time in the future. It has the advantages of convenient construction, high safety performance, high construction efficiency and high turnover efficiency.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solution of this utility model, and these modifications or equivalent substitutions cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of this utility model.
