Ultrahigh large-span concrete cast-in-place beam bailey truss framework construction method

Abstract

Disclosed is an ultrahigh large-span concrete cast-in-place beam bailey truss framework construction method. The measures such as erecting lattice columns and bailey trusses are adopted. The method comprises the steps of arranging a lattice column foundation, erecting the lattice columns, mounting cross bridgings among the columns, installing a top movable head, erecting cover beams, erecting the bailey trusses, installing distributive beams, mounting a side protective barrier, laying a keel, laying templates and the like. A simple framework supporting system which is small in occupied site, solid and reliable and convenient to install and disassemble is formed, a great deal of conventional steel tube floor scaffold material input is avoided, and at the same time, the labor intensity of workers is also reduced. The ultrahigh large-span concrete cast-in-place bailey truss framework construction method can adapt to ultrahigh large-span concrete cast-in-place beam projects in various building constructions.

Description

technical field [0001] The invention relates to a construction method for installing high formwork, in particular to a construction method for formwork support of super-high and large-span concrete cast-in-place beams. Background technique [0002] In the field of architecture, public amusement buildings are developing in the direction of larger, taller, more complex, more diverse structural forms, more complete functions, and more comprehensive. Large-scale all-weather amusement buildings require a tall shared space, so that the column spacing needs to be larger to meet the structural layout of the amusement space. These spaces also require a large load platform beam. The conventional pure steel structure cannot meet its load requirements and requires a large span. Concrete structure or concrete stiff structure. The construction formwork of these ultra-high and large-span reinforced concrete structures has become the focus and difficulty in construction. In actual enginee...

Problems solved by technology

In actual engineering construction, fastener-type steel pipe scaffolding is usually used to solve the problem of high formwork in the construction of such structures, but the height and length of the fastener steel pipe frame are affected by the rigidity and stability of the frame, resulting in the length and height of the erection frame. very restrictive
