Problems solved by technology

The common shear seismic reinforcement methods mostly use clad steel plates to make up for the lack of shear strength, but these methods have actually provided shear stirrups in the rods, that is to say, this type of The rods covered and reinforced by steel plates actually use the joint action of steel plates, transverse stirrups, longitudinal main bars and concrete to provide their shear strength and flexural strength, which makes the construction cost higher

[0016] The first embodiment: as Figure 2-Figure 3c As shown, a base portion 230 , a column 220 and a cap beam 210 are included. The column 220 is arranged on the base part 230, and the column 220 includes a column core structure 221, a shear force structure 222 and a plurality of longitudinal steel bars 223, the shear force structure 222 is set on the surface of the column core structure 221, and the longitudinal steel bar 223 is set on the column core structure In 221, column 220 has no stirrup structure. The cap beam 210 is provided on the column. The above-mentioned column core structure 221 can be made of concrete, and the shear resistance structure 222 can be a plurality of steel pipes, and the steel pipes can be connected by welding. Between the shear resistance structure 222 (steel pipe) and the column center structure, shear studs can be added to strengthen the connection between the steel pipe and the column center structure. There may be a distance d1 between the...

[0017] The second embodiment: as Figure 4 As shown, the multiple steel pipes of the shear structure 222 are not welded but a distance d2 is left to simplify the construction procedure. When d2 is extremely small, this spacing does not affect the shear strength of the overall structure, which still has sufficient shear strength. In the embodiment of the present invention, the steel pipe can be used as the construction formwork of the concrete column (column core structure 221 ) to simplify the construction process. The specific steps are as follows: 1. Form the foundation. 2. Arrange multiple longitudinal steel bars on the foundation. The longitudinal steel bars can be fixed with iron wires or small steel bars to maintain the position of these longitudinal steel bars, but it is not necessary to arrange shear-resistant transverse stirrups. 3. Set at least one steel pipe to cover the longitudinal reinforcement. 4. Concrete is poured into the steel pipe, so that the longitudina...

Abstract

The invention relates to a composite beam-column structure for building construction. The composite beam-column structure comprises a foundation part, a column and a cap beam; the column is arranged on the foundation part and comprises a column core structure, a shearing-force-resistant structure and a plurality of longitudinal steel bars; the shearing-force-resistant structure is arranged on thesurface of the column core structure, and the longitudinal steel bars are arranged in the column core structure; the cap beam is arranged on the column; the column core structure is made of concrete;the shearing-force-resistant structure comprises a plurality of steel pipes which are connected in a welded mode, meanwhile a distance is formed between all the steel pipes, and the distance is smaller than the width of the cross section of the column; and additionally, a distance is also formed between the shearing-force-resistant structure and the foundation part, and a distance value is also smaller than the width of the cross section of the column.

Description

technical field [0001] The invention relates to a beam-column structure for building construction, in particular to a composite beam-column structure. Background technique [0002] In recent years, due to successive strong earthquakes at home and abroad, many beam structures and bridge structures have been damaged in these earthquakes. In the previous design standards, the shear force design of reinforced concrete members is usually based on the strength It is the focus of investigation, but at present, with the development of seismic codes, the importance of shear stirrups to the toughness of members is gradually being paid attention to. The common shear seismic reinforcement methods mostly use clad steel plates to make up for the lack of shear strength, but these methods have actually provided shear stirrups in the rods, that is to say, this type of The rods clad and reinforced by steel plates actually use the joint action of steel plates, transverse stirrups, longitudina...
