Description

Technical Field

[0001] The utility model relates to a jacking bracket for jacking up a terminal building grid frame, and belongs to the technical field of jacking up a terminal building grid frame. Background Art

[0002] When the terminal building is supported by a grid structure, the grid is usually first jacked up to the required height after being installed on the ground. Since the grid is relatively large, multiple telescopic hydraulic rods are usually used to support multiple connection nodes of the grid and then jacked up simultaneously. During the jacking process, multiple standard sections are stacked for support.

[0003] The existing truss jacking is shown in Chinese patent announcement number CN111719705A, and the disclosed technology is: the piston rod of the hydraulic cylinder rises synchronously by one stroke, and the second standard section is installed above the first standard section, so that the cylinder body of the hydraulic cylinder rises, and the crossbeam is moved to the second standard section to complete one stroke; although the truss jacking is achieved by increasing the installation of standard sections after the hydraulic cylinder rises, the standard sections have more components, and assembling the standard sections in the area to be installed after the hydraulic cylinder rises will reduce the construction efficiency. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a jacking bracket for jacking up the terminal building grid.

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

[0007] Retractable jacking piece;

[0008] Standard sections with upper and lower detachable fixed overlapping connections;

[0009] The standard sections at the upper and lower parts include two symmetrical standard frames of the overall structure;

[0010] The upper angle steel and the lower angle steel are detachably fixedly connected to the two standard frames horizontally;

[0011] Angle steel for detachably fixing the upper and lower angles of two standard frames;

[0012] The standard frames at the upper and lower standard sections are detachably fixedly connected to each other.

[0013] The upper cylinder body and the lower cylinder body of the jacking member are fixed with a base A and a base B respectively; the two sides of the base A are supported on the upper standard section by a crossbeam A; the two sides of the base B are supported on the lower standard section by a crossbeam B, and the jacking member is supported in the middle of the upper and lower standard sections by the base A and the base B.

[0014] The standard frame located at the lower standard section is detachably fixed with a clamp A and a clamp B, and the clamp A is hinged with an auxiliary arm. The bottom of the auxiliary arm is rotatably hinged on the clamp A, and the middle part of the auxiliary arm is tied to the clamp B through a retractable adjustable telescopic rod, and the telescopic end of the adjustable telescopic rod is detachably connected to the auxiliary arm; the standard frame located at the upper standard section is detachably fixed with a clamp C, and the clamp C is detachably and fixedly connected to the auxiliary arm.

[0015] The beneficial effect of the utility model is that after the jacking member is extended to lift the grid node of the terminal grid to appear the area to be installed, the standard frame of the standard section is installed as a whole on the top of the standard frame of the lower standard section through the auxiliary arm docking, and then the upper angle steel, lower angle steel and bevel steel are removably fixed to the upper and lower horizontal and diagonal connections of the two standard frames to form a new standard section at the upper part, which solves the problem of reducing construction efficiency when assembling standard sections with many components in the area to be installed after the hydraulic cylinder rises.

DETAILED DESCRIPTION

[0020] The technical solution of the utility model is further described below, but the scope of protection required is not limited to the description.

[0021] like Figures 1 to 3 shown.

[0022] A lifting bracket for lifting a terminal grid frame in the present application includes:

[0023] A lifting member 2 supporting a grid node 1 of the terminal grid is a telescopic hydraulic cylinder.

[0024] The upper cylinder and lower cylinder of the jacking member 2 are fixed with bases A21 and B22 respectively; the base A21 is supported on the upper standard section 3 by beams A23 on both sides, so that the base A21 supports the upper cylinder of the jacking member 2, and the beam A23 is detachable for contact installation; the base B22 is supported on the lower standard section 3 by beams B24 on both sides, so that the base B22 supports the lower cylinder of the jacking member 2, and the beam B24 is detachable for contact installation. The jacking member 2 is supported in the middle of the upper and lower standard sections 3 through the bases A21 and B22.

[0025] The standard section 3 at the upper and lower parts includes a standard frame 31 of the overall structure, and the standard frame 31 is two symmetrical ones;

[0026] The upper angle steel 32 and the lower angle steel 33 are detachably fixedly connected to the two standard frames 31 horizontally up and down;

[0027] Angle steel 34 is used to detachably and fixedly connect the upper and lower bevels of the two standard frames 31 .

[0028] The standard frame 31 located at the lower standard section 3 is detachably fixed with a clamp A41 and a clamp B42, and the clamp A41 is hinged with an auxiliary arm 5, and the bottom of the auxiliary arm 5 is rotatably hinged on the clamp A41, and the middle part of the auxiliary arm 51 is tied to the clamp B42 through a retractable adjustable telescopic rod 52, and the telescopic end of the adjustable telescopic rod 52 is detachably connected to the auxiliary arm 51; the standard frame 31 located at the upper standard section 3 is detachably fixed with a clamp C43, and the clamp C43 is detachably fixedly connected to the auxiliary arm 51. The standard frames 31 in the upper and lower standard sections 3 are detachably fixedly connected to each other. The detachable fixed connection involved in the text can be realized by bolts and nuts, etc.

[0029] When there are multiple lower standard sections 3, the height of the supporting grid node 1 of the lifting member 2 is relatively high. When installing the upper standard section 3, the two standard frames 31 that have become an integral whole are connected to the top of the standard frame 31 of the lower standard section 3 from both sides, and then the two standard frames 31 are detachably fixedly connected to form a whole through the upper angle steel 32, the lower angle steel 33 and the bevel steel 34, thereby forming a new standard section 3 to support the base A21 of the upper cylinder body of the lifting member 2.

[0030] The present application provides a terminal building grid jacking construction method, comprising:

[0031] The lifting member 2 is extended, and the upper cylinder of the lifting member 2 is lifted with the base A21. The top of the upper cylinder of the lifting member 2 is lifted against the grid node 1 of the terminal grid. The two standard frames 31 that have become a whole are connected to the top of the standard frame 31 of the lower standard node 3 from both sides. Figure 1 Status shown;

[0032] The standard frame 31 is stabilized in the position by the auxiliary arm 51, and the upper angle steel 32, the lower angle steel 33 and the oblique angle steel 34 are removably fixed to the upper and lower horizontal and diagonal connections of the two standard frames 31, thereby forming a new upper standard section 3, and the rear crossbeam A23 supports the base A21 on the newly formed upper standard section 3, such as Figure 2 Status shown;

[0033] The lifting member 2 retracts upward, and the base B22 of the lower cylinder of the lifting member 2 is lifted. The base B22 is supported on the new standard section 3 at the lower part through the crossbeam B24. The auxiliary arm 51 is disassembled, lifted and installed on the new standard section 3 at the upper part. The standard frame 31 of the new standard section 3 at the upper part is detachably fixed to the standard frame 31 of the old standard section 3 at the lower part by bolts and nuts, preparing for the next lifting.

[0034] Since the standard frame 31 of the standard section 3 is connected as a whole to the top of the standard frame 31 of the lower standard section 3 through the auxiliary arm 51, and then the upper angle steel 32, the lower angle steel 33 and the bevel angle steel 34 perform detachable fixed connection on the upper and lower horizontal and diagonal sides of the two standard frames 31, a new standard section 3 at the upper part is formed, which solves the problem of reducing construction efficiency when assembling standard sections with more components in the area to be installed after the hydraulic cylinder rises.
