T-shaped concrete filled steel tube specially-shaped column applied to industrial production

Abstract

The invention relates to a T-shaped concrete filled steel tube specially-shaped column applied to industrial production. The T-shaped concrete filled steel tube specially-shaped column comprises steel plates, through long bolts and concrete, and is characterized in that the steel plates comprise a side steel plate (7), two inner angle steel plates (6) and three edge slot steel plates (8), wherein the side steel plate (7) comprises a middle part (7-1), two end parts (7-2) and two side surface parts (7-3), the inner angle steel plates (6) comprise corner parts (6-1), two end parts (6-2) and two side surface parts (6-3); the side steel plate (7), the two inner angle steel plates (6) and the edge slot steel plates (8) are welded to form the T-shaped specially-shaped column, cross sections of the middle part and the three end parts of the T-shaped specially-shaped column are square, the corresponding side parts between the side steel plate (7) and the inner angle steel plates (6) as well as between the inner angle steel plates (6) are fixedly connected through the through long bolts, and concrete is poured into the T-shaped specially-shaped column. The T-shaped concrete filled steel tube specially-shaped column is applied to industrial batch production and can be rapidly spliced on construction site.

Description

Technical field [0001] The invention belongs to the technical field of building structures and relates to an assembled special-shaped steel pipe concrete column. Background technique [0002] The concrete-filled steel tube structure is composed of steel tubes filled with concrete. It uses the interaction of steel tubes and concrete in the stress process, that is, the restraint of the steel tubes on the core concrete, so that the concrete is in a state of three-way compression, so that the concrete The strength is improved and the ductility is improved; at the same time, due to the existence of concrete, the premature local buckling of the steel pipe can be delayed or avoided to ensure the full performance of the steel performance. In the construction process of steel pipe concrete, the steel pipe can be used as the pouring formwork of its core concrete. Compared with reinforced concrete, it can save the cost of the formwork and speed up the construction speed. [0003] The ...

AI Technical Summary

Problems solved by technology

At present, the concrete-filled steel pipe special-shaped columns with plate connection or strip connection are widely used. The defect of these special-shaped columns is that the factory processing is very cumbersome, which is not conducive to batch industrial production. The quality of large and shaped columns cannot be guaranteed

[0004] In order to solve the problems that the concrete-filled steel tube special-shaped columns cannot realize industrialized mass production and the on-site installation and construction procedures are complicated, it is necessary to find a form of steel-filled steel tube special-shaped columns that can not only realize industrialized mass production, but also can be quickly installed and constructed on site.
