Description

Technical Field

[0001] This utility model relates to the field of construction protection technology, and more specifically to a support frame for concrete lining construction. Background Technology

[0002] In the construction of concrete linings for water conservancy, tunnels, municipal engineering and other projects, the support frame is a key piece of equipment to ensure the dimensional accuracy and forming quality of the lining structure. It is used to press the lining plate tightly against the inner wall of the concrete lining to prevent collapse.

[0003] A search revealed an existing patent (publication number: CN220319574U) that discloses a support frame for concrete lining construction. During use, the adjusting screws on the left and right sides of the synchronous adjusting component are connected to two sets of support frames. Rotating the synchronous adjusting component causes the two sets of support frames to move in opposite directions, which facilitates synchronous adjustment and control of the support force of the support frame on the concrete lining, ensuring uniform stress on the concrete lining and improving the balance of the support frame. However, in the process of realizing this utility model, the inventors discovered the following problems with the existing technology: First, when the above-mentioned support frame for concrete lining construction uses support plates to support the side walls of the concrete lining, the length of the support plates needs to match the side height of the concrete lining. Then, the support frame structure is used to support the support plates. In this case, when the height of the concrete lining is different, resulting in the need to use multiple support plates of different lengths, the support position of the support frame is difficult to match the position of the support plates. Second, when the above-mentioned support frame for concrete lining construction supports the top arc-shaped support plate, its support position and angle are fixed. When the top arc of the concrete lining is different, it is difficult to complete the support task, thus resulting in poor adaptability.

[0004] In view of this, the present invention proposes a support frame for concrete lining construction to solve this problem. Utility Model Content

[0013] Furthermore, the vertical support beam has several positioning grooves equidistantly spaced on the side away from the side liner, and positioning blocks are fitted onto the surface of the tensioning screw, with the positioning blocks being engaged inside the positioning grooves.

[0015] Furthermore, the top support assembly includes a swing seat rotatably connected to the surface of the transverse support beam. The swing seat is threadedly connected to an extension screw, and the surface of the extension screw is threadedly connected to a second locking nut.
