Problems solved by technology

For example, if the box-shaped steel frame steel concrete column is built in, the steel frame material is far away from the neutral axis, which can provide a large moment of inertia, but when the side length of the steel frame is long or the thickness of the steel plat

Embodiment

[0028] Such as figure 1 , figure 2 As shown, the box-shaped steel-reinforced concrete column with round steel tie rods includes box-shaped steel frame 1, round steel tie rods 2, longitudinal steel bars 3, composite stirrups 4, and concrete 5; On the basis, a round steel tie rod is added to form.

[0029] According to the technical solution of the present invention, the manufacturing steps of the box-shaped steel-framed concrete column with round steel tie rods are as follows:

[0030] 1) The factory prefabricated the welded box-shaped steel frame 1, and punched holes along the height in the middle of the side steel plate;

[0031] 2) Locate the round steel tie rod 2 and screw the nut on the outside of the side steel plate of the box-shaped steel frame 1 to apply pre-tightening force;

[0032] 3) After the prefabricated and welded steel frame members are transported to the site and positioned, the longitudinal reinforcement 3 and the composite stirrup 4 are bound;

Abstract

The invention relates to a steel bone concrete column, and particularly relates to a box-type steel bone-confined concrete column with round steel draw bars. The box-type steel bone-confined concrete column with the round steel draw bars comprises a box-type steel bone, the round steel draw bars, longitudinal reinforcement, a composite stirrup and concrete, wherein the round steel draw bars are connected with steel plates at two opposite edges of the box-type steel bone through bolts in the middles of the steel plates in a sectioning manner, so that the calculated length of each edge steel plate of the box-type steel bone is effectively reduced, the buckling deformation of each edge steel plate is constrained, and meanwhile, the inspection capability of internal concrete of the steel bone is enhanced by existence of the round steel draw bars. The round steel draw bars are arranged at intervals, so that the pouring quality of the concrete is ensured when the edge steel plates of the box-type steel bone are constrained. 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 box-shaped steel frame restrained concrete column with round steel tie rods 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 plates or dire...
