Beam-column concrete pouring dense-type combined formwork in building construction

Abstract

The invention provides a beam-column concrete pouring dense-type combined formwork in building construction. The beam-column concrete pouring dense-type combined formwork comprises a column formwork,wherein the column formwork is a rectangular frame formed by buckling a plurality of column modules, an opening is formed in one side of the upper end of the column formwork, a beam formwork is arranged at the position of the opening, the cross section of the beam formwork is of a U-shaped structure, an opening of the beam formwork is upward, and the end of the beam formwork is connected with theopening of the column formwork through a connecting plate. According to the beam-column concrete pouring dense-type combined formwork in building construction, the connection strength between the column formwork and another column formwork is improved through the mutual fastening among the column modules, connection blocks and beam modules, the use of a screw connection mode is reduced, the disassembly and assembly are convenient, and the labor intensity is reduced; positioning ribs penetrate through through holes vertically or horizontally to fasten the adjacent column modules and beam modules, splicing seams are reduced, the connection strength between the beam formwork and the column formwork is further enhanced, the assembly is simple and easy, and the engineering practicability is high.

Description

technical field [0001] The invention belongs to the technical field of building construction, in particular to a compact combined formwork for concrete pouring of beams and columns in building construction. Background technique [0002] Since the technical policy of "replacing wood with steel" was put forward in the 1970s, composite steel modules have been widely used in various parts of our country, especially in the north. Combined steel formwork is suitable for various cast-in-place reinforced concrete projects, and can be assembled into large-scale formwork for beams, columns, walls, and floors according to design requirements. The traditional combined steel formwork is difficult to disassemble and assemble during use, which causes increased labor intensity for the operator; the large joints of the combined steel formwork can easily cause concrete leakage, and the connection strength of the corners is low, resulting in poor construction quality and other problems.
