L-shaped steel concrete special-shaped column of supporting angle steel framework

Abstract

The invention discloses an L-shaped steel concrete special-shaped column of a supporting angle steel framework, which comprises an L-shaped concrete special-shaped column; section steel is configured in the L-shaped concrete special-shaped column and is connected by angle steel into an L-shaped lattice type space angle steel framework through steel lace pieces. The L-shaped steel concrete special-shaped column has the beneficial effects that the difficulty of pouring during the construction of the L-shaped steel concrete special-shaped column of a solid web steel end plate configured at the end part of a column limb in the limb width direction and inconvenience when a steel bar passes through a beam column node area are solved; and through reasonably configuring the angle steel and the steel lace pieces, the transverse deformation of concrete in the L-shaped steel concrete special-shaped column can be restrained, and a cohesive effect between steel and concrete is enhanced, so that the bearing capacity of the column self is improved, and the use scope of the special-shaped column is enlarged.

Description

technical field [0001] The invention relates to a combined structure of steel and concrete, in particular to an L-shaped steel concrete special-shaped 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 ...

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
