Construction method of narrow space wall based on integral assembly of large formwork

Abstract

The invention relates to a large formwork narrow space wall body construction method based on integral assembly. The large formwork narrow space wall body construction method is characterized in thatan outer side formwork is provided with built-in bolts connected with split bolts; pressure dispersion plates are arranged outside the built-in bolts; pull rod connecting plates are arranged outside the outer side formwork; first supporting ribs are arranged between first supporting rib limiting grooves and second supporting rib limiting grooves. Second supporting ribs are arranged between a second stand column and a first stand column; a load bearing plate, an inclined support and a pull rib are arranged between the column foot of the first stand column and the floor; longitudinal limiting bodies are arranged at connecting positions of the second stand column, an inner side formwork and the floor; a plate bottom limiting body is pre-arranged in a poured concrete wall body; a flexible filling layer is arranged at the connecting position between the outer side formwork and the plate bottom limiting body; a longitudinal outer support is arranged between the outer side formwork and the adjacent outer side wall body; and the outer side formwork is disassembled by a sliding formework guide bracket. Wall formwork arranging and disassembling efficiency is improved, formwork arranging quality is improved, and material utilization ratio is improved.

Description

technical field [0001] The invention relates to a concrete wall construction method, in particular to a method for constructing a wall in a narrow space based on an integrally assembled large formwork with high formwork support and positioning accuracy, good formwork structure integrity, and convenient on-site disassembly and assembly of the support system, which belongs to the field of construction engineering , suitable for wall construction projects in narrow spaces. Background technique [0002] With the advancement of urban construction in our country, the building density inside the urban area is getting higher and higher, and the resulting building spacing is getting smaller and smaller. The problem of formwork support in narrow spaces has gradually become a bottleneck that plagues current engineering construction and affects the quality of engineering construction.

The problem of formwork support in narrow spaces has gradually become a bottleneck that plagues current engineering construction and affects the quality of engineering construction

[0003] In the prior art, there is a wall formwork technology for narrow spaces, which includes assembling wood wool boards, wooden squares, scaffolding pipes, gables, pull bolts, and nuts into an integral formwork, and hoisting the outer formwork into place by a crane. The inner formwork is assembled by pulling screws and other components, and then the wall is concreted. Finally, the inner and outer formwork of the wall are dismantled, and the whole formwork is hoisted out through the cooperation of the tower crane. Although this technology solves the problem of wall formwork support in narrow spaces, it does not The hoisting construction of the overall formwork is difficult, and the installation and positioning accuracy of the overall formwork is difficult to guarantee; at the same time, when the wall concrete is poured, this technology does not take effective measures to support the inner and outer formwork laterally, and the quality of the wall formation is not easy to control
