Description

Technical Field

[0001] This utility model relates to the field of foundation pit support in building construction, specifically a hydraulic locking device for prefabricated steel supports. Background Technology

[0002] Prefabricated steel angle braces are widely used in foundation pit support structures. However, ordinary steel angle braces are difficult to make the steel support reach the top support state. After the ordinary hydraulic prefabricated steel support is completed, the foundation pit support will still deform, resulting in the steel support not being under stress. Utility Model Content

[0003] To address the problems existing in the prior art, this utility model provides a hydraulic locking device for prefabricated steel supports, comprising a first support block, a second support block, a first connecting member, a second connecting member, and a hydraulic self-locking compensation member. The first support block is wedge-shaped and includes a first pressing surface abutting against the first connecting member, a second pressing surface abutting against the second support block, and a third striking surface for striking. A first rack is provided on the second pressing surface. The second support block is connected to the second connecting member and includes a fourth pressing surface adapted to the second pressing surface on the first support block. A second rack adapted to the first rack is provided on the fourth pressing surface. The hydraulic self-locking compensation member includes a fixed end and a movable end. The fixed end is disposed on the second connecting member, and the movable end points towards the first connecting member and can be pressurized to abut against the first connecting member. The first and second connecting members are used for foundation pit support, and a fifth pressing surface adapted to the first pressing surface is provided on the first connecting member.

[0004] In use, the first and second connecting components are abutted against the inner wall of the pit. The hydraulic self-locking compensation component then pressurizes the inner wall of the pit by abutting against the first and second connecting components. After pressurization, the first support block is placed between the first connecting component and the second support block, so that the first and fifth pressing surfaces abut against each other, and the second and fourth pressing surfaces abut against each other. Then, the third striking surface is struck, causing the first and second racks to mesh, completing the mechanical locking of the pit support. After installation, the hydraulic self-locking compensation component is retained, and weekly pressurization and striking of the first support block are maintained to ensure the pit support remains in a supported state.

[0005] Furthermore, in use, the height of the first support block is greater than the height of the second support block, which makes it easier to strike the first support block and allows for a wider range of selectable pressure lengths.

[0006] Furthermore, there are two of each of the first and second support blocks, and the two second support blocks are arranged at the same height on the second connecting member. The fixed end of the hydraulic self-locking compensation mechanism is located on the second connecting member between the two second support blocks, making the whole device stable.

[0007] Furthermore, the first rack is a right-angled rack, comprising a plurality of teeth.

[0008] Furthermore, all teeth are of equal length, ranging from 0.8 to 1.5 cm, which facilitates control over the length of pressure applied.

[0009] Furthermore, it also includes a compensation block, which includes a compensation part and a limiting part. The compensation part is used to abut against the fifth extrusion surface and the first extrusion surface, and the limiting part is used to abut against the top of the first connecting member, so that when the distance between the first connecting member and the second connecting member is large, a suitable compensation block can be selected to shorten the distance between them.

[0010] Furthermore, there are several compensation blocks with compensation sections of different thicknesses.

[0011] Furthermore, it also includes a third connecting member, which is used to abut against the foundation pit and the corresponding first connecting member and / or second connecting member for ease of use.

[0012] Furthermore, the second support block is a hollow structure, and a first reinforcing plate is provided inside the second support block. The first reinforcing plate is arranged along the pressure direction, which helps to reduce the overall weight of the device.

[0013] Furthermore, the first connecting member and the second connecting member are hollow structures, and a second reinforcing plate is provided inside the first connecting member and the second connecting member. The second reinforcing plate is arranged along the pressure direction, which helps to reduce the overall weight of the device.

[0014] This utility model, through in-depth research on hydraulic steel support structures, adopts a force-holding device for hydraulic steel supports, which solves the problem that ordinary steel supports lose force due to deformation of the foundation pit support after the top support is completed. Compared with servo hydraulic steel supports, it has a lower cost, and the force-holding device of the steel support provides higher mechanical structural safety. Attached Figure Description
