Description

Technical Field

[0001] The utility model relates to the technical field of building construction devices, in particular to a pre-tensioned hollow slab beam hinged seam reinforcement adjusting device. Background Art

[0002] Hollow slab bridges are mostly constructed by prefabricated assembly. The prefabrication quality of the hollow slab is guaranteed, but the hinged joint is a post-cast section. Therefore, this part is relatively weak and is the main part for bridge diseases.

[0003] In order to avoid damage to the hinged joint of the bridge, the construction quality of the hinged joint steel bars is very high during the construction process. In the existing technology, the method of leveling the embedded steel bars in the hinged joint is often to use a crowbar to pry them flat. Some steel bars are closely attached to the beam and slab, and it is difficult for the crowbar to find a fulcrum. The construction process is time-consuming and labor-intensive, and the construction speed is very slow. Moreover, it is difficult to ensure the straightness of the steel bars when adjusting the steel bars with a crowbar, and the stress characteristics of the hinged joint steel bars cannot be fully utilized. In addition, the traditional leveling method is affected by factors such as people, tools and working surfaces, and the work efficiency is extremely low.

[0004] In order to solve the above problems, there is a hinged joint reinforcement adjustment device for hollow slab beams in the prior art, which mainly adjusts the hinged joint embedded reinforcement by means of the lever principle; however, such an adjustment method has certain defects, and it is necessary to connect one end to the gate reinforcement at the top of the beam, while the part connected to the hinged joint embedded reinforcement is a fixed position. This method makes it not universally applicable. If the distance between the gate reinforcement at the top of the beam and the gap is far or close, the parts connected to the hinged joint embedded reinforcement will be inconvenient to use.
