Description

Technical Field

[0001] The utility model belongs to the technical field of application of prefabricated assembled bridge construction engineering, and specifically relates to a prefabricated assembled cap beam installation alignment adjustment device. Background Art

[0002] With the progress of society and the improvement of people's environmental awareness, the construction environment of bridges has received more and more attention from the government and the people, especially the core bridges in the city. The construction period of bridges, construction noise pollution, and traffic pressure have gradually become the primary considerations in bridge design. Prefabrication technology has the advantages of standard component production, fast and convenient on-site installation, and energy-saving and environmentally friendly construction. It can reduce the impact on the atmospheric environment and traffic roads, improve quality and safety, and civilized construction level.

[0003] As the name suggests, prefabricated and assembled bridges are different from traditional on-site construction methods such as steel bar tying and concrete pouring. For prefabricated bridges, part or all of the components of the bridge's substructure (piers, abutments, cap beams) and superstructure (box beams, slab beams, T-beams) are processed and formed in a prefabricated component factory and then transported to the construction site for hoisting and assembly into the bridge body.

[0004] The various components of the bridge are mechanically connected through embedded holes, embedded steel bars and connecting devices processed during the prefabrication process. Grouting is carried out using grouting sleeves in the components so that concrete fully fills the pores between the components to achieve overall strengthening.

[0005] After searching: Application No. / Patent No. 202223052906.7 discloses a quick positioning device for cap beam installation, which belongs to the field of bridge installation, and includes a pier body, and fixing mechanisms are provided on both sides of the outside of the pier body, and stabilizing frames are fixedly connected on both sides of the fixing mechanism, and a support frame is fixedly connected to the top of the stabilizing frame, and a No. 1 motor is provided inside the support frame, and a bidirectional screw rod is fixedly connected to the output shaft of the No. 1 motor, and a slider is connected to the external thread of the bidirectional screw rod, and a guide plate is fixedly connected to the top of the slider; the present application is novel in design and ingenious in structure. The quick positioning device for cap beam installation can better guide and position bridges of different shapes and sizes by providing a support frame, a No. 1 motor, a bidirectional screw rod, a slider and a guide plate, thereby avoiding the problem that most cap beam installation quick positioning devices are difficult to guide and position bridges of different shapes, thereby bringing convenience to the use of the cap beam installation quick positioning device.

[0006] The applicant has analyzed and found that in the above technical solution: the guide plate can only guide the cap beam close to the pier body during assembly; as is well known, during assembly, the cap beam is lifted to the top of the pier body (bridge column) by lifting equipment, and the cap beam will swing after lifting. The earlier the lifted cap beam is limited and guided, the higher the efficiency and accuracy of assembly will be. Therefore, how to adaptively solve the problem of earlier intervention (limiting, guiding) of the cap beam after lifting is the current research and development problem.

[0007] Therefore, based on the above-mentioned problem, the utility model provides a prefabricated assembled cap beam installation alignment adjustment device. Utility Model Content
