Embodiment

[0028] Such as figure 1 , figure 2 As shown in , the concrete column with flanged cross-shaped steel frame constrained by the patch plate includes the flanged cross-shaped steel frame 1, the constraint patch plate 2, the longitudinal steel bar 3, the composite stirrup 4, and the concrete 5; it is built in The cross-shaped steel-reinforced concrete column foundation is formed by adding the flange of the cross-shaped steel frame and the restraint plate.

[0029] According to the technical solution of the present invention, the fabrication steps of the panel-constrained cross-shaped steel frame-constrained concrete column with flanges are as follows:

[0030] 1) Factory prefabricated welded cross-shaped steel frame with flange 1;

[0031] 2) Position the restraint plate 2 and weld it to the flange of the cross-shaped steel frame with flange 1;

[0032] 3) After the prefabricated and welded steel frame members are transported to the site and positioned, the longitudinal reinfo...

Abstract

The invention relates to a steel bone concrete column, and particularly relates to a batten plate constraint type confined concrete column with a cross steel bone with flanges. The batten plate constraint type concrete column disclosed by the invention comprises the cross steel bone with the flanges, constraint batten plates, longitudinal reinforcement, a composite stirrup and concrete, wherein the constraint batten plates are respectively welded and connected with two adjacent flanges of the cross steel bone with the flanges in a sectioning manner, so that free extension length of each flange is effectively reduced, buckling deformation of the flanges is constrained, meanwhile, the inspection capability of internal concrete of the steel bone is enhanced by existence of the constraint batten plates. The constraint batten plates are arranged at intervals, and the internal part of the steel bone is communicated with external concrete in series, so that the pouring quality of the concrete is ensured. Therefore, the concrete disclosed by the invention has the relatively high strength and the good elastic-plastic deformation capacity, and the formed steel bone concrete column has the relatively high bearing capacity, ductility and energy-dissipating capacity.

Description

technical field [0001] The invention relates to a panel-constrained concrete column with a cross-shaped steel frame constrained by a flange and a method thereof, which are mainly used in the field of anti-seismic energy consumption in building structures. Background technique [0002] Steel-reinforced concrete structure refers to a composite structure system in which steel reinforcement is arranged in an ordinary reinforced concrete structure. In the steel reinforced concrete structure, the steel frame can be divided into two types: solid belly type and hollow type. The solid-web steel-reinforced concrete members have better seismic performance, while the seismic performance of the empty-web steel-reinforced concrete members is basically the same as that of ordinary reinforced concrete members. Therefore, at present, solid-web steel-reinforced concrete members are mostly used in earthquake-resistant structures. The solid-belly steel frame can be assembled by welding steel ...
