Abstract

The invention provides a cover beam of a semi-prefabricated assembly type high-performance concrete formwork, comprising a bottom plate which is formed by splicing a plurality of bottom plate module end blocks and bottom plate module middle blocks; the web plate is formed by splicing a plurality of web plate module end blocks and a plurality of web plate module middle blocks; the multiple opposite-pull constraint assemblies are arranged on the web module end blocks and the web module middle blocks; and the two cover plates are respectively arranged on the two sides of the web plate. According to the cover beam of the semi-prefabricated assembly type high-performance concrete formwork and the construction method, the cover beam formwork can be prefabricated and modularly produced in a factory, a finished product can be hoisted and poured after being transported to a site, the construction efficiency is improved, the cover beam formwork made of ultra-high performance concrete (UHPC) serves as a permanent formwork for pouring concrete, and the construction cost is reduced. Formwork amount and manufacturing cost are omitted, construction procedures are simplified, the bottom plate and the web plate are divided into a plurality of assemblies, and transportation and hoisting difficulty is effectively reduced.

Description

technical field [0001] The invention relates to the technical field of bridge engineering construction, in particular to a cover beam of a semi-prefabricated assembled high-performance concrete formwork and a construction method. Background technique [0002] In recent years, with the continuous development of urban bridge construction and prefabricated buildings, the overall construction level of bridges has improved rapidly. At this stage, the construction of cover beams generally adopts three methods: pouring concrete on site, transporting on-site hoisting after overall prefabrication, semi-hoisting. On-site hoisting and pouring of prefabricated formwork [0003] In the commonly used method of on-site formwork pouring concrete to make cover beams, the construction team needs to carry out work formwork on the piers for enclosure construction. This method has many problems, such as long construction period, many wastes, and unstable construction quality. At the same time, ...
