Erecting structure of variable cross-section beam-column-free cap

Abstract

The invention relates to the field of buildings, in particular to an erecting structure of a variable-section beam-column-free cap. The erecting structure of the variable cross-section beam-column-free cap Comprises a bottom lining plate, triangular trusses and column cap formworks, the triangular trusses are uniformly and vertically arranged along the periphery of a stand column hole, the columncap formworks are laid on the upper end faces of the triangular trusses, each column cap formwork comprises a first inclined plate and a second inclined plate, and the inclination angle alpha of the first inclined plates is larger than the inclination angle beta of the second inclined plates. According to the variable cross-section beam-column-free cap, steel bars and concrete materials are saved,the formworks are convenient to erect, the inclination angle is convenient to control, and the forming quality is good.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to an erection structure of a beamless column cap with variable cross-section. Background technique [0002] The current beamless column caps are mainly square column caps, and there are also inverted tapered beamless column caps, but the inclination angle of the inverted cone beamless column caps does not change. This structure has poor load-bearing capacity and requires steel bars and The amount of material such as concrete is relatively large. The beamless column cap has passed the structural check calculation. The inverted cone and variable inclination angle column cap can save materials such as steel bars and concrete to the greatest extent, but it will cause great difficulty in construction. , When pouring concrete, it is easy to deform, run out of the mold and leak grout, and the molding quality is poor. [0003] In the existing construction projects, diffe...

[0002] The current beamless column caps are mainly square column caps, and there are also inverted tapered beamless column caps, but the inclination angle of the inverted cone beamless column caps does not change. This structure has poor load-bearing capacity and requires steel bars and Large amount of materials such as concrete

The beamless column cap has passed the structural check calculation. The inverted cone and variable inclination angle column cap can save materials such as steel bars and concrete to the greatest extent, but it will cause great difficulty in construction. , when pouring concrete, it is easy to deform, run out of the mold and leak grout, and the molding quality is poor

[0003] In the existing construction projects, different building structures are based on the consideration of their load-bearing capacity and safety angle. Designers have different designs for the specific inclination angles of the beamless column caps on different construction projects. The existing beamless column caps are under construction. During the construction process, it is necessary to pre-set up the corresponding erection formwork on the spot before construction, but there is a large demand for beamless column caps in construction, and beamless column caps with different inclination angles require each construction party to be sure before construction. Re-installing the formwork will cause waste of formwork erection materials, reduce construction efficiency, and cause unnecessary economic losses
