Description

Technical Field

[0001] This utility model relates to the field of building engineering, and more specifically, to a device for fixing C-shaped paving boards on Bailey beams. Background Technology

[0002] A top-formwork platform is a multi-layered integrated work platform that combines construction equipment and material storage areas. The top of the platform serves as the primary material storage area. A common practice is to lay C-shaped steel plates on Bailey bridge beams, connecting them by welding the steel plates to the upper chord of the Bailey bridge beams. This connection method is inefficient, time-consuming, labor-intensive, and environmentally unfriendly. The welded steel plates suffer significant wear and tear, hindering material turnover and cost control. Furthermore, the welding process generates substantial residual stress in the Bailey bridge beams, posing a potential structural safety hazard. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a device for fixing C-shaped paving panels on Bailey beams, which does not damage the structure and has high installation efficiency.

[0004] The technical solution adopted by this utility model to solve its technical problem is as follows: a device for fixing a C-shaped plank to the upper chord of a Bailey beam is constructed, including a pull plate, a tail screw, a nut and a connecting bolt. The C-shaped plank is laid on top of the upper chord of the Bailey beam. The pull plate is fixed to the tail end of the tail screw. The pull plate has a reserved hole. The connecting bolt passes through the reserved hole and is fixedly connected to the C-shaped plank. The threaded end of the tail screw is fixedly connected to the upper chord of the Bailey beam through a clamp and a nut.

[0005] In the above scheme, the threaded end of the tail screw passes through the clamping plate, and the nut is tightened on the tail screw, so that the clamping plate is in close contact with the lower surface of the upper chord of the Bailey beam.

[0006] In the above scheme, the pull tab is welded and fixed to the tail end of the tail screw.

[0007] In the above scheme, multiple C-shaped paving boards arranged side by side are fixedly connected by the connecting bolts.

[0008] In the above scheme, the pull plate and the tail screw are located between the upper chords of the two Bailey beams.

[0009] In the above scheme, the C-shaped paving plate is provided with mounting holes for connecting bolts to pass through.

[0010] The device for fixing C-shaped paving boards on Bailey beams according to this utility model has the following beneficial effects:

[0011] The device for fixing C-shaped paving plates on Bailey beams provided by this utility model eliminates the need for welding C-shaped paving plates to the upper chord of Bailey beams, and adopts on-site assembly and bolt installation, making on-site operation more environmentally friendly and installation more efficient.

[0012] The present invention will be further described below with reference to the accompanying drawings and embodiments. In the accompanying drawings:

[0013] Figure 1 This is a schematic diagram of the structure of the device for fixing C-shaped decking on Bailey beams according to this utility model;

[0014] Figure 2 This is a structural diagram of the pull tab and the tail screw. Detailed Implementation

[0015] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0016] like Figure 1-2 As shown, the device for fixing C-shaped paving boards on Bailey beams according to this utility model includes a pull plate 1, a tail screw 2, a nut 4, and a connecting bolt 7.

[0017] C-shaped paving 6 is laid above the upper chord 5 of the Bailey beam; in this embodiment, it is a steel paving plate. A tie plate 1 is fixed to the tail end of the tail screw 2. The tie plate 1 has pre-drilled holes through which connecting bolts 7 pass and are fixedly connected to the C-shaped paving plate 6. The threaded end of the tail screw 2 is fixedly connected to the upper chord 5 of the Bailey beam via a clamping plate 3 and a nut 4. The threaded end of the tail screw 2 passes through the clamping plate 3, and the nut 4 is tightened onto the tail screw 2. The nut 4 ensures that the clamping plate 3 is tightly pressed against the lower surface of the upper chord 5 of the Bailey beam, thus completing the fixation.

[0018] Preferably, the pull tab 1 is welded and fixed to the tail end of the tail screw 2. The pull tab 1 and the tail screw 2 can also be manufactured by integral molding.

[0019] Preferably, multiple C-shaped paving plates 6 arranged side by side are fixedly connected by connecting bolts 7, and the ends of the connecting bolts 7 can also be tightened by nuts.

[0020] Preferably, the pull tab 1 and the tail screw 2 are located between the upper chords 5 of the two Bailey beams.
