Movable formwork system and construction method thereof

Abstract

The invention relates to a movable formwork system and a construction method thereof. The movable formwork system comprises an II-shaped aluminum mold supporting plate, a horizontally-arranged transverse truss girder, a plurality of top contraction and expansion parts, two vertically-arranged vertical truss columns, a horizontal supporting parts and a plurality of vertical supporting parts. Chamfers are arranged at bevels of the aluminum mold supporting plate. The transverse truss girder abuts against an inner top plate of the aluminum mold supporting plate. The side walls of the two vertical truss columns abut against the two inner side walls of the aluminum mold supporting plate. Sliding sleeving parts which are parallel to the transverse truss girder are fixedly arranged at the upper ends of the two vertical truss columns, and the side faces of the sliding sleeving parts are in a U shape. Rod parts of the lower portions of the two ends of the transverse truss girder are sleeved with the sliding sleeving parts of the two vertical truss columns correspondingly. The sliding sleeving parts can slide along the rod parts of the lower portion of the transverse truss girder. One end of each top contraction and expansion part is fixedly connected with the lower portion of the transverse truss girder, and the other end of each top contraction and expansion part is fixedly connected with the adjacent vertical truss column. The vertical truss columns on the two sides are enabled to draw together to the middle or stretch to the two sides through hydraulic contracting or stretching of the top contraction and expansion parts.

Description

technical field [0001] The invention relates to a mobile formwork system and a construction method thereof, which is suitable for the initial lining construction stages of underground pipe galleries, culverts and tunnels, and belongs to the field of construction engineering. Background technique [0002] For the construction of the culvert roof by the traditional scaffolding method, a bowl-shaped scaffolding bracket or ordinary Φ48 steel pipes are used to build a full house scaffolding with corner fasteners. The internal rod system consists of vertical rods (according to a certain longitudinal distance and horizontal distance), horizontal rods (according to a certain step distance), scissors braces (set up according to a certain angle and distance, and the scissors braces with large volumes are also divided into horizontal scissors braces, Longitudinal scissors bracing, horizontal scissors bracing) support system, jointly support the jacking, main keel (square wooden beam), ...

AI Technical Summary

Problems solved by technology

During the construction process of the overall channel type culvert formwork, it is still very complicated to disassemble after installation. Underground pipe galleries, culverts and tunnels are generally constructed in sections, and repeated installations are required during the gradual completion process, which consumes labor and affects the overall construction.
