Abstract

The invention discloses an integrated construction method of a cast-in-place box beam inclined web formwork. The method includes the steps that firstly, the installation of a cast-in-place box beam ring lock support and bottom plate transverse I-steel is carried out; then, a plurality of inclined web supporting frames are installed on the corresponding bottom plate transverse I-steel respectively,and after the installation is completed, the length of adjustable supporting beams of the inclined web supporting frames is adjusted to ensure that the included angle between an inclined web and a bottom plate meets the installation drawing requirements of the inclined web; finally, the installation of the inclined web formwork is carried out, and acceptance inspection is carried out. According to the method, the inclined web supporting frames are adopted for supporting and positioning the inclined web formwork to ensure that the installation of the inclined web meets the drawing requirements, fixed supporting beams of the inclined web supporting frames are used for supporting an inclined web form and a chamfered arc form, and thus the supporting rigidity and strength are guranateed. Theconstruction method of the cast-in-place box beam inclined web formwork is simple, the installation is fast, the construction process is greatly simplified, and the construction cost is greatly reduced.

Description

technical field [0001] The invention relates to the construction field of cast-in-place box girders, in particular to an integrated construction method for oblique web formwork of cast-in-place box girders. Background technique [0002] With the continuous emergence of urban traffic congestion, urban viaducts are becoming more and more popular. After decades of development, the construction technology of cast-in-place box girders for viaducts is becoming more and more mature. How to efficiently and safely complete the construction of cast-in-place box girders, and to be widely recognized by owners, supervisors, and industry experts, has always been the long-cherished wish of bridge engineers. The cross-sectional form of the cast-in-place box girder bottom plate and side plate, side plate and wing plate is generally rounded or directly chamfered. The traditional wing and side panels usually use pre-bent steel pipes and put them on the bracket top bracket for temporary suppor...
