T-shaped steel reinforced concrete special-shaped column of supporting steel frame

Abstract

The invention discloses a T-shaped steel reinforced concrete special-shaped column of a supporting steel frame. The T-shaped steel reinforced concrete special-shaped column of the supporting steel frame comprises a T-shaped concrete special-shaped column; section steel is configured in the T-shaped steel reinforced concrete special-shaped column, and is connected to be a T-shaped lattice-type space angle steel frame through a steel studding element. According to the invention, the problems that the pouring difficulty of a column limb end part of the T-shaped steel reinforced concrete special-shaped column is matched with a solid web steel end plate and reinforced steel is inconvenient to penetrate at beam column node zones are solved; through the reasonable configuration of angle steel and steel studding element, the horizontal deformation of concrete in the T-shaped steel reinforced concrete special-shaped column can be restricted; the cementing effect between reinforced steel materials and concrete is intensified, so that the bearing capability of the column is improved; and the using range of the special-shaped column is expanded.

Description

technical field [0001] The invention relates to a combined structure of steel and concrete, in particular to a T-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 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
