Description
Technical Field
The invention relates to a novel steel pipe special-shaped column, in particular to a latch hook connected H-shaped steel and channel steel assembly type cross special-shaped column cross applied to the field of buildings.
Background
The special-shaped column is used as a deformation form of the traditional rectangular column, so that an external corner and a column edge do not appear indoors, the arrangement effect of a room is further improved, and the space utilization rate is improved. The traditional special-shaped column can be divided into a reinforced concrete special-shaped column, a steel reinforced concrete special-shaped column, a combined special-shaped column, a pure steel special-shaped column and the like according to different used materials.
The reinforced concrete special-shaped column is a form which is mostly used at the earliest, the design concept of the reinforced concrete special-shaped column is similar to that of the reinforced concrete short-limb shear wall, and the reinforced concrete special-shaped column can be obtained from the reinforced concrete short-limb shear wall by reducing the height-thickness ratio of the cross section of the wall limb. The steel reinforced concrete special-shaped column is an improved form aiming at the defects of low bearing capacity, strict axial compression ratio limit value, small ductility and the like of the steel reinforced concrete special-shaped column. The structure of the reinforced concrete special-shaped column is usually in a form of arranging steel ribs in the reinforced concrete special-shaped column, and the steel ribs and the reinforced concrete act together, so that the integral bearing capacity, rigidity and durability can be effectively improved. However, the section of each column limb is narrow, the wrapping thickness of the concrete to the steel rib is small, the cooperative work of the steel rib and the concrete is difficult to guarantee, and the concrete protective layer is prone to falling off too early in the stress process, so that the bearing capacity of the concrete protective layer is seriously influenced. Compared with the reinforced concrete special-shaped column, the bearing capacity, the ductility and the deformation performance of the steel reinforced concrete special-shaped column are obviously improved, but the beam column node still needs more steel bars to increase the shearing resistance, the structure is complex, the construction is difficult, and the mechanical property is greatly influenced by the concrete. The box-shaped steel plate special-shaped column is one of steel pipe concrete special-shaped columns, the box-shaped steel pipe outside the box-shaped steel plate special-shaped column is formed by welding steel plates, the steel-concrete combined box-shaped steel plate special-shaped column can be formed by pouring concrete inside the box-shaped steel plate special-shaped column, but the common combined box-shaped steel plate special-shaped column is easy to generate local buckling too early in the stress process, the steel pipe and the concrete at the internal corner are easy to separate,
at present, students propose various forms of combined box-shaped steel plate special-shaped columns with constraint pull rods or stiffening ribs, multi-cavity box-shaped steel plate special-shaped columns, combined box-shaped steel plate special-shaped columns connected by batten plates and the like on the basis of 2 ideas of enhancing the coordination work of steel pipes and concrete and the constraint action of the steel pipes on the concrete, reducing the size of units in the columns and increasing the stability of each steel plate in the units.
These forms of machining require a large number of welding processes. A large number of welding processes easily cause the steel plate to be heated and deformed, and have the defects of environmental pollution and cost increase.
