Guide device for assembling and positioning prefabricated polygonal bridge pier and design method

Abstract

The invention relates to the technical field of infrastructure construction, in particular to a guide device for assembling and positioning a prefabricated polygonal bridge pier and a design method. The guide device comprises a plurality of position limiting plate assemblies, wherein the position limiting plate assemblies are connected with the bridge pier to form a guide surface; each position limiting plate is at least connected with two positioning pull buckle assemblies and two positioning top buckle assemblies; one end of each positioning pull buckle assembly and one end of the corresponding positioning top buckle assembly are connected with the corresponding position limiting plate through a screw bolt; and the other end of each positioning pull buckle assembly and the other end of the corresponding positioning top buckle assembly are connected with a corresponding embedded steel bar. The guide device and the design method have the advantages that assembly type components are used and combined to form a whole; field transportation and movement are convenient; the embedded steel bars of the structure per se are used for positioning and force bearing; the installation is convenient; the device is light and ingenious; guide hole passages formed by the position limiting plates in a vertical curved surface form have the big upper side and the small lower side, the bridge pierpositioning deviation in the construction process can be allowed, and the construction difficulty is reduced; and the plates are mutually combined, position limiting holes are transversely adjustable,and adaptability to different types of polygonal prefabricated bridge piers can be realized.

Description

technical field [0001] The invention relates to the technical field of infrastructure construction, in particular to a guide device and a design method for assembling and positioning prefabricated polygonal bridge piers. Background technique [0002] In the field of infrastructure construction, after the prefabricated pier segments are prefabricated in the factory, they are transported to the construction site by various means of transportation, hoisted to the designated location by hoisting equipment such as cranes, and assembled with the structure completed in the previous construction. In general, the prefabricated bridge pier sections have corresponding reserved tunnels on the structures completed in the previous construction, and each tunnel of the prefabricated bridge pier sections needs to be hoisted at this time. The structural pre-embedded steel bars completed in the pre-order construction are paired up one by one, and the assembly is completed through the pre-embed...

AI Technical Summary

Problems solved by technology

The hoisting and assembling of prefabricated bridge piers under the existing technical conditions is slow and time-consuming, which conflicts with the concept of mechanized and rapid construction of prefabricated bridges

[0004] At present, relevant patents in this field are mainly concentrated on the hoisting device, which is mainly aimed at the equipment for hoisting prefabricated pier segments and the construction of auxiliary facilities. Assembled positioning device and its design method
