Z-shaped steel concrete specially-shaped column provided with steel angle frame

Abstract

The invention discloses a Z-shaped steel concrete specially-shaped column provided with a steel angle frame. The Z-shaped steel concrete special-shaped column comprises a Z-shaped concrete specially-shaped column, wherein the Z-shaped concrete specially-shaped column is internally provided with a profile steel, and the profile steel is formed by the means that angle steels are connected with one another by steel pendants to form a Z-shaped lattice type space angle steel framework. After the Z-shaped steel concrete specially-shaped column disclosed by the invention is used, the casting difficulty and the steel (steel bar) penetrating inconveniency within a beam column panel point region caused when the end of a column limb part is compactly provided with the Z-shaped concrete specially-shaped column of a web steel end plate along the limb width direction can be solved; and according to the reasonable arrangement of the angle steels and the steel pendants, the transverse deformation of the concrete within the column can be restrained, and the cohesive action between the steel and the concrete can be enhanced, so that the carrying capacity of the column per se can be improved, and the use range of the specially-shaped column structure can be enlarged.

Description

technical field [0001] The invention relates to a combined structure of steel and concrete, in particular to a Z-shaped special-shaped steel concrete column with an angle steel skeleton. Background technique [0002] Modern civilization has led to a change in people's aesthetic concepts of things. As a vertical load-bearing member in a frame structure—column, its traditional form is a rectangular cross section. The special-shaped column structure has the characteristics of the same thickness as the infill wall, so it avoids the column flute protruding from the wall, increases the actual usable area of ​​the room, and improves the "household rate", which is favored by owners and users. With the continuous development of commercial buildings such as residences and offices towards high-rise and super-high-rise buildings, the width of the column limbs of the special-shaped column structure is bound to increase. Promotional use. Our country has a vast territory, most of which a...

Problems solved by technology

However, considering factors such as the ratio of steel in the section and the thickness of the infill wall, the thickness of the steel cover of the special-shaped steel concrete column has a certain limit, and some even can only meet the minimum cover thickness, which leads to the distance between the outer edge of the column and the outer surface of the steel. The space between them is relatively narrow. During construction, it is very easy to produce coarse aggregate in the concrete, which is difficult to drop due to the slightly larger particle size of the aggregate, and difficult to vibrate. As a result, the concrete pouring of the protective layer is not dense, which affects the structural column itself. Moreover, at the staggered part of the beam-column joint area, it is difficult for the longitudinal steel bars in the beam to penetrate into the core area of ​​the joint due to the blockage of the solid web steel in the column, which is most likely caused by improper anchorage measures at the beam end. The force transmission of the node fails, and the consequences are extremely serious
