TEMPORARY SUPPORT SYSTEM FOR ROAD BRIDGE PRE-FABRICATED SMALL BOX GIRDER-TYPE CONCEALED BENT CAP, AND METHOD OF CONSTRUCTING SAME
Document Type and Number:
WIPO Patent Application WO/2021/078309
Kind Code:
A1
Abstract:
A temporary support system for a road bridge pre-fabricated small box girder-type concealed bent cap, and a method of constructing same. The support system comprises a main beam (11), a main pier support system, and lateral pier support systems; the main beam (11) is arranged on the transverse side the road bridge piers; the main pier support system is disposed on the transverse side of a main pier area and is located under the main beam (11); the lower end of the main pier support system is fixed to a main pier bearing platform (21), whereas the upper end is fixed to the main beam (11); each lateral pier support system is disposed on the transverse side of a lateral pier area and is located below the main beam (11); and the lower end of each lateral pier support system is fixed to a lateral pier bearing platform (31), whereas the upper end is fixed to the main beam (11). Between the main pier area and the lateral pier areas there is only a large-span main beam (11) arranged in the transverse direction, and no other support systems arranged in the vertical direction. This allows for vehicle operating space, and thus facilitates assembly and disassembly of the present support system. In addition, the support system has a high load-bearing capacity, thus meeting support requirements for pre-fabricated small box girder-type concealed bent caps.
