Embodiment Construction

[0020] Such as figure 2 As shown, the T-shaped column of the inner truss type concrete filled steel pipe of the present invention mainly includes the outer steel pipe 1, the inner truss 2, the strip 3 and the filled concrete 4. Among them, the outsourcing steel pipe is ∏-shaped or in-line shape (that is, flat steel plate), and the inner truss is composed of T-shaped steel and strips, roughly forming a column-shaped frame structure. In this embodiment, the number of T-shaped steels is 6, of which 2 T-shaped steels 2 are located at two adjacent corners, and the other 4 T-shaped steels form 2 pairs of inner truss subunits 2a, that is, 2 The flange plates of a T-shaped steel are welded vertically, and the flange plates of two T-shaped steels are L-shaped. The strips are welded on the web of the T-shaped steel along the longitudinal direction. In this embodiment, there are three rows of strips, which are respectively welded on the web of the T-shaped steel and the T-shaped steel ...

Abstract

The invention discloses an inner truss type concrete-filled steel tube T-shaped column and a construction method thereof, wherein the inner truss type steel tube concrete T-shaped column includes an outsourcing steel tube, an inner truss and filled concrete; wherein the inner truss is roughly a Column frame, including T-shaped steel, inner truss sub-units welded by T-shaped steel, and strips welded to adjacent T-shaped steel webs along the longitudinal direction of T-shaped steel; the cross-section of the outer steel pipe is Π-shaped or straight; the outsourcing steel pipe is fixedly connected with the flange plate of the T-shaped steel to form a column with a T-shaped cross-section. The special-shaped column of the invention has the advantages of high bearing capacity and strong stability of the steel plate, and the inner truss does not divide the section of the column, so it is convenient to pour concrete. In addition, the present invention does not need to set up formwork and arrange steel bars, and the construction is quick and convenient.

Description

technical field [0001] The invention relates to a special-shaped steel pipe concrete column, in particular to an inner truss type special-shaped steel pipe concrete column. Background technique [0002] With the development of society and the gradual improvement of residents' living standards, residents generally hope that the four corners of the house can be smooth, neat and beautiful. This forms the design idea of ​​the special-shaped column structure. However, with the gradual increase of high-rise and ultra-high-rise buildings and the increase of the upper load, the bearing capacity of traditional reinforced concrete special-shaped columns can no longer meet the engineering requirements for bearing capacity. [0003] Compared with the traditional reinforced concrete structure, due to the hoop effect of the outer steel pipe on the concrete in the core area, the compressive bearing capacity of the column has been significantly improved. However, there are still many prob...
