Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and specifically to a quick fixing device for misaligned platforms. Background Technology

[0002] Current methods for fixing misaligned tunnel segments primarily address the instability of shield tunnels, where segment misalignment occurs, with the fixing points located at the misalignment points. The main construction methods employed are welding steel plates together and bolting steel plates to the segments. The differences between these methods lie mainly in the dimensions of the materials used and the location of the connections.

[0003] Traditional technical solution: Steel plate welding reinforcement process. Typically, steel plates of appropriate thickness are cut according to the height difference between the misaligned segments, and the steel plates are fixed to the lower segment. Then, the steel plates and the upper segment are welded together. While this method can fix the misaligned segments, during subsequent construction, axial or longitudinal pressure on the segments may cause the welds to break, leading to the failure of the fixation between the misaligned segments. Summary of the Invention

[0004] The purpose of this utility model is to overcome the defects of the prior art and provide a quick fixing device for misaligned sections. In use, the first fixing plate and the second fixing plate can be fixed to the two sections that are misaligned, and the first fixing plate and the second fixing plate can be fixed by screws, thereby increasing the longitudinal and axial resistance of the sections.

[0007] A second fixing plate is fixedly installed on the upper segment of the tube. A portion of the second fixing plate extends above the first fixing plate to form a fixing section. The fixing section has a through hole corresponding to the threaded hole.

[0008] A screw rod passing through the through hole, the bottom of the screw rod being threadedly connected to the threaded hole; and

[0009] A nut is threaded onto the screw, and the nut is located on top of the second fixing plate. By screwing the nut, the bottom of the nut is pressed against the top of the second fixing plate.

[0010] Furthermore, the first fixing plate is fixed to the lower segment by expansion bolts.

[0011] Furthermore, the second fixing plate is fixed to the upper segment by expansion bolts.

[0012] Furthermore, multiple threaded holes are provided, and the screw and the through hole are provided with multiple threaded holes corresponding to the multiple threaded holes.

[0014] Furthermore, the second fixing plate is made of steel.

[0015] Furthermore, the diameter of the through hole is larger than the diameter of the screw, and the diameter of the through hole is smaller than the outer diameter of the nut.

[0016] Compared with the prior art, this utility model has the following advantages:

[0017] In use, the first and second fixing plates can be fixed to the two segments that are misaligned, and the first and second fixing plates can be fixed with screws, thereby increasing the longitudinal and axial resistance of the segments. Attached Figure Description
