Rectangular structure lining outer model trolley for grading open cut tunnel

Abstract

The invention provides a rectangular structure lining outer model trolley for a grading open cut tunnel, and relates to the technical field of building construction equipment. The lining outer model trolley comprises a formwork system, a gantry system and a model fixing and releasing system; the cross section of the gantry system is pi-shaped, and the gantry system includes a beam structure on theupper portion and column structures on both sides; the formwork system includes side models opposite on both sides; the two side models are located in an inner cavity of the gantry system and are hinged to the top inner wall of the gantry system; the model fixing and releasing system is disposed between the formwork system and the gantry system to fix the gantry system and the two side models anddrive the side models to swing relative to the gantry system. The rectangular structure lining outer model trolley adopts the gantry system with the pi-shaped cross section, the side models oppositeon both sides are arranged, a traditional bulk disassembling formwork and a bowl buckle bracket system are replaced, the rigidity is high, the stability is good, the integrity of a concrete structureand design size requirements are ensured, and the degree of construction automation and the construction efficiency are improved.

Description

technical field [0001] The invention relates to the technical field of building construction equipment, in particular to a trolley for the outer formwork of a rectangular structure lining of a grading open-cut tunnel. Background technique [0002] With the rapid improvement of my country's urbanization level and the progress of engineering design and construction technology, open-cut tunnels, which are restricted by special conditions, have emerged as an important form of construction structure in the construction of high-speed railways. [0003] In existing and traditional technologies, formwork support systems are generally used for the side wall and roof construction of cut-and-open rectangular tunnels, most of which are loose formwork and bowl buckle support systems. This method requires the use of wall-penetrating screws. It needs to be assembled and disassembled piece by piece, and because the side walls and roof are constructed separately, there are many working proce...
