Novel temporary support for bridge construction

Abstract

The invention relates to a novel temporary support for bridge construction and relates to the technical field of bridge supports. The novel temporary support comprises a base, a plurality of supporting columns and a plurality of bearing tables. The base is arranged on the ground of a construction site. A connecting column is arranged at the bottom end of each supporting column; inserting grooves are formed in the base, bearing sleeves sleeve the top ends of the supporting columns, the top ends of the bearing sleeves are fixedly connected with connecting tables, inserting grooves penetrating through the connecting tables in the direction perpendicular to the axes of the bearing sleeves are formed in the top walls of the connecting tables, inserting blocks matching the inserting grooves arearranged at the bottom ends of the bearing tables, and the bearing tables are connected with the supporting columns through matching of the inserting grooves and the inserting blocks. According to thetemporary support, all the components of the temporary support are assembled in a spliced mode; when a worker installs the temporary support, the worker only needs to assemble all the components in sequence according to the steps, and the situation that the overall structural strength is affected due to unstable welding quality caused by environmental factors, the operation level of the worker and the construction environment is reduced.

Description

technical field [0001] The invention relates to the technical field of bridge supports, in particular to a novel temporary support for bridge construction. Background technique [0002] The temporary support of the bridge is a temporary project in the bridge erection. Although it is a temporary project, it is indeed a very important and indispensable part. In the erection of prefabricated box girders and T girders, a temporary support is first set on the top of the pier, and then the prefabricated box girder and T girder are erected on the temporary support. After completing the processes of wet joints, wet joints, negative moment tensioning and grouting, the temporary support is removed to complete the system conversion. [0003] The existing temporary support includes a base, a support column and a load-bearing platform structure, the base is placed on the ground, the support column is arranged on the base, and the load-bearing platform is arranged on the top of the supp...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned existing technical solutions have the following defects: after the construction process, the temporary support needs to be disassembled and recovered, since all parts are connected by welding, but under the influence of the construction personnel's operating level, construction environment and tool quality , the welding levels are different, making it difficult to effectively guarantee the overall strength of the temporary support
