Problems solved by technology

[0005] The manufacturing precision of the steel components of the mobile formwork is high, the cross-sectional size of the components is large, and the weight of a single piece is heavy, making it difficult to manufacture, assemble, turn over, weld and other processes. The joints between the sections, between the sections of the guide beam and between the main beam and the guide beam are prone to deformation during the assembly and welding process, resulting in the overall straightness not meeting the requirements. Therefore, the main beam and guide beam manufacturing process How to control deformation and improve assembly accuracy is an important issue

Abstract

The invention relates to a manufacturing process of a self-propelled movable formwork main beam structure. The process comprises the following specific operation steps: 1) manufacturing a main beam body; 2) manufacturing a guide beam; 3) manufacturing a bottom die truss; and 4) assembling the main beam structure. According to the manufacturing process of the self-propelled movable formwork main beam structure, manufacturing precision is controlled through a reversible deformation jig frame and a reasonable technological process, and the manufactured main beam structure is good in overall straightness, high in precision, convenient to transport and assemble, high in construction and manufacturing speed, beneficial to shortening a construction period and capable of saving construction cost.

Description

technical field [0001] The invention relates to the technical field of self-propelled mobile formwork, in particular to a manufacturing process and main beam structure of a self-propelled mobile formwork main beam structure. Background technique [0002] Mobile formwork, also known as sliding formwork support system and MSS bridge building machine, is a construction machine with its own formwork, which uses caps or pier columns as supports to cast bridges on site. As an advanced construction equipment, due to the advantages of good construction quality, easy operation and high efficiency, mobile formwork has been widely used in the continuous beam construction of highways, road bridges and railway bridges. [0003] Mobile formwork is divided into two types: self-propelled mobile formwork and non-self-propelled mobile formwork. Self-propelled mobile formwork is widely used because of its own function. Please refer to figure 1 , figure 1 It is a structural schematic diagram...
