Embodiment 1

[0043] A connection structure of beam reinforcement welded lugs in a stiffened concrete column, such as figure 1 , figure 2 As shown, the connection structure includes several ear plates and steel pipe columns 3; the ear plate includes a connecting ring plate 1 and several stiffening plates 2, and the bottom of each individual stiffening plate 2 stands on the connecting ring plate 1 on the inner plane of the stiffening plate 2; the bottom of the stiffening plate 2 is fixedly connected to the plane of the connecting ring plate 1, and the side perpendicular to the bottom is fixedly connected to the pipe wall of the steel pipe column; each independent ear plate is connected along the plane of the connecting ring plate 1 One side is fixed around the steel pipe column 3 pipe walls.

[0044] In some embodiments, the connecting ring plate 1 is perpendicular to the pipe wall of the steel pipe column 3 , and the side along the plane of the connecting ring plate 1 is connected to the ...

Embodiment 2

[0048]A connection structure between beam reinforcement and steel pipe columns at joints, such as Figure 3-Figure 6 As shown, it includes the connection structure of the welded ear plate of the beam reinforcement in the stiffened concrete column, the first row of main reinforcement 4, the second row of main reinforcement 5, and the third row of main reinforcement 6; the first row of main reinforcement 4 is welded in the connection On the outer plane of the ring plate 1 , the second row of main ribs 5 is welded on the inner side of the connecting ring plate 1 , and the third row of main ribs 6 is welded on both sides of the stiffening plate 2 .

[0049] The first row of main ribs 4, the second row of main ribs 5 and the connecting ring plate 1 are welded by double-sided lap joints. The lap length is L1, and L1 is 5 times the diameter of the first row of main ribs 4; the third row of main ribs 6 Double-sided lap welding is adopted between the stiffener plate 2, and the lap leng...

Abstract

The invention relates to the field of building construction, in particular to a connecting structure of a beam steel bar welding lug plate in a stiff concrete column. The connecting structure comprises a plurality of lug plates and a steel pipe column, wherein each lug plate comprises a connecting ring plate and a plurality of stiffening plates, and the bottom of each individual stiffening plate stands on the plane of the connecting ring plate; the bottom of each stiffening plate is fixedly connected with the plane of the corresponding connecting ring plate 1, and the side perpendicular to the bottom of each stiffening plate is fixedly connected with the pipe wall of the steel pipe column; and each independent lug plate is fixed around the pipe wall of the steel pipe column along one side on the plane of the corresponding connecting ring plate 1. The problem that the beam main reinforcement is difficult to construct due to the fact that the space of the stiff concrete column at the beam-column joint is limited is solved, the connecting structure has the advantages that the construction process is simplified, the forming quality is improved, raw materials are easy to obtain, the assembly and welding process is simple, and popularization is easy.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a connection structure of welded lug plates for beam reinforcement in stiffened concrete columns. Background technique [0002] Stiffened concrete composite structural members are often used in high-rise or long-span structures. Sectional steel is added to the original reinforced concrete beams, columns and other components to increase the bearing capacity of the components and reduce the axial compression ratio of the components. However, after adding steel columns at the beam-column joints, the construction of the main reinforcement of the beam becomes difficult due to the limited space. [0003] In order to solve the above problems, there are two conventional methods. The first method is to weld the ring plate around the steel column, and the beam main reinforcement is welded to the ring plate. However, when the main reinforcement of the beam is designed with multiple ro...
