Problems solved by technology

[0004] In the above-mentioned prior art, the stirrups include shaped steel stirrups. In the first connection structure of the shaped steel stirrups, one end of the shaped steel stirrups is pierced with a stirrup hole and hooked to the rib plate, and the shaped steel stirrups are connected by iron wires. The ribs are tied to the floor, and the other end of the shaped steel stirrup is hooked to the corresponding steel bar. However, the above-mentioned shaped steel stirrups are open-type stirrups that are independent of each other. The construction personnel need to connect the open-type stirrups many times, and the construction

Example Embodiment

[0039] Example one:

[0040] Combine figure 1 with figure 2 As shown, a structure for connecting steel-concrete structural columns and stirrups includes a steel-reinforced steel column 1 fixed by vertical welding. A number of longitudinal steel bars 2 are arranged and fixed on the peripheral side of the steel-reinforced column 1 according to design requirements. A stirrup 3 is connected between the steel column 1 and the longitudinal reinforcement 2. In this embodiment, the section steel column 1 is set as a box section steel. The box section steel includes four first webs 4 vertically arranged and welded to form a longitudinally extending box structure, and the inside of the box section steel A cross-shaped frame 11 for reinforcement is welded. The first web 4 is welded with stirrup connecting plates 5 at symmetrical positions along its width direction. The stirrup connecting plates 5 are welded and fixed to the outer surface of the first web 4 in the longitudinal direction, a...

Example Embodiment

[0044] Embodiment two:

[0045] Such as image 3 As shown, the difference between a steel reinforced concrete structural column and a stirrup connection structure from the first embodiment is that: in this embodiment, the steel reinforced column 1 of H-shaped steel is adopted; the H-shaped steel includes a second web 6 , Both ends of the second web 6 are integrally formed or welded and fixed with the first end plate 61, and the first end plate 61 and the second web 6 are arranged perpendicularly; the reinforcing nail 12 is welded and fixed to the outside of the first end plate 61 On the side. The stirrup connecting plate 5 is welded and fixed to the two outer sides of the second web 6, and the stirrup connecting plate 5 is welded and fixed to any one of the outer sides of the second web 6 at one third of its width .

Example Embodiment

[0046] Embodiment three:

[0047] Such as Figure 4 As shown, a type of steel concrete structural column and stirrup connection structure, the difference from the first embodiment is: in this embodiment, the cross-shaped steel profile steel column 1; the cross-shaped steel includes a cross-shaped structure The third web 7 can be formed by welding four third webs 7, or an integrally formed cross structure with four third webs 7, and the stirrup connecting plate 5 is welded and fixed to the first Three webs 7 on the outside surface. The four ends of the cross-shaped structure formed by the third web 7 are welded and fixed with a second end plate 71, and the second end plate 71 and the third web 7 are arranged perpendicularly; the reinforcing nail 12 is welded and fixed to the second end plate 71 on the outside surface.

[0048] The four third webs 7 are coplanar in pairs; the stirrup connecting plates 5 on the third webs 7 arranged in a coplanar group are set as the first stirrup c...

Abstract

The invention discloses a connecting structure and construction method of steel ribs and hoops of a steel rib concrete structure column and relates to the technical field of steel rib concrete structure column construction. The BIM technology is used for establishing data models of profile steel rib columns, longitudinal reinforcing steel bars and the hoops, and meanwhile, the size and the positions of hoop connecting boards and the hole diameter and the forming positions of run-through holes are determined; and binding, buckling and fixing operation of the hoops, the profile steel rib columnsand the longitudinal reinforcing steel bars is finished on the site. In the hoop connection construction process of the profile steel concrete structure column, the longitudinal hoop connecting boards are welded to profile steel column webs, the hoops are buckled to the hoop connecting boards, web perforation and hoop welding construction are not needed, construction operation efficiency can be improved, the profile steel web section loss ratio can be reduced, hoop connection reliability can be guaranteed, the profile steel stress performance is improved, meanwhile, cost can be saved, a construction period can be shortened, and construction operation difficulty and construction personnel labor intensity are reduced.

Description

technical field [0001] The invention relates to the technical field of construction of a steel-reinforced concrete structural column, in particular to a connection structure of a steel frame and a stirrup of a steel-reinforced concrete structural column and a construction method thereof. Background technique [0002] In recent years, with the increasing number of high-rise and super high-rise buildings in China, reinforced concrete structures have been fully utilized and developed. However, in the traditional perforation and welding construction methods used in some steel concrete structural column stirrups, there are problems such as long construction time, many welding times, and heavy workload, which reduces construction efficiency and increases construction costs, and cannot meet the construction needs of the project. . [0003] The existing authorized announcement number is the Chinese patent of CN208168164U, which discloses the connection structure of the stirrups in ...
