Formwork-free fabricated frame structure

Abstract

A fabricated frame structure free of formwork erecting is formed by combining a column formwork frame, floor bottom formwork assemblies, angle steel for connecting the combined floor bottom formwork assemblies, floor bottom formwork assembly combining seams, main beams, rib beams, steel net-shaped body built-in formworks and concrete. The column mold frame is manufactured by vibrating cold-drawn wire concrete under the action of a special mold; the floor slab bottom mold assembly is an inorganic composite plate bottom mold assembly; the inorganic composite plate bottom mold assembly is formed by splicing N inorganic composite plates through angle steel for connection, and the length of the inorganic composite plate bottom mold assembly is equal to that of a column net; column holes are reserved in the beam-column combination portions of the bottom die assembly. A functional fixing piece is arranged in the angle steel for connection; the adjacent distance of the steel mesh body built-in mold forms the width of a longitudinal rib beam or the width of a main beam; the concrete is directly compounded with the disassembly-free bottom die assembly and the built-in die to form an assembly type frame structure of the disassembly-free column die frame, the floor slab bottom die and the steel mesh body built-in die.

Description

technical field [0001] The invention relates to a prefabricated building system technology, in particular to a formwork-free prefabricated frame structure technology. Background technique [0002] At present, the development of the prefabricated reinforced concrete frame structure system is relatively lagging behind. In the prefabricated reinforced concrete structure project, the prefabricated reinforced concrete shear wall structure is mainly used, which is a part or all of the prefabricated load-bearing shear wall components. The external wall panels generally adopt prefabricated sandwich wall panel technology; most of the floor slabs use truss slabs; the large-span factory building project has just started, and the cast-in-situ concrete frame structure is used to laminate the double T floor slab. [0003] The prefabricated reinforced concrete frame structure is the focus and difficulty of the prefabricated building, and there are major problems: ① The beam-column has no j...

Problems solved by technology

[0006] The purpose of the present invention is to use the organic combination of column formwork, floor slab bottom formwork components, and steel mesh built-in formwork components to form the column, beam, and slab molds required for the large-span assembled reinforced concrete frame structure. Columns, beams, and slab reinforcements are respectively set in the post-cast concrete to form an assembled frame structure free of formwork; the present invention "uses rigid-flexible inorganic composite panels to form strip-shaped bottom formwork components and built-in formwork free from support through connecting angle steels." The prefabricated combined floor slab technology of the formwork" replaces the "truss laminated slab technology in the shear wall structure system with heavy mass, small area and small span"; at the same time, the bottom formwork assembly of the floor slab eliminates the necessary floor covering of the cast-in-place hollow floor The formwork overcomes the problems of anti-floating, displacement, and cumbersome workmanship caused when the bottom of the cast-in-place hollow floor filling body must be cast-in-place concrete to form the floor slab; it makes full use of the floor slab bottom formwork components and the steel mesh built-in formwork components to organically Combining the main beam and rib beam molds of the prefabricated floor slab without formwork, the existing frame structure technology system is optimized, which lays the foundation for the realization of the large-span prefabricated building frame structure; it not only improves the overall safety of the prefabricated building frame structure , and solve the problem that the existing frame structure adopts double T-slab superposition or truss superposition slab floor technology. series of flaws
