Abstract

The invention discloses a multi-chamber type steel tube concrete special-shaped column, consisting of U-shaped steel, a rectangular steel tube and concrete cast in the tube. The U-shaped steel is mutually welded with the rectangular steel tube to form special-shaped columns with different sections. The whole section is divided into a plurality of chambers by the U-shaped steel and the rectangular steel tube, and the concrete is filled in the chambers. The U-shaped steel is formed by bending or welding a steel plate and the rectangular steel tube is formed by directly welding or first blending and then welding the steel plate. By dividing the section into a plurality of chambers, the special-shaped column can enhance the interaction between the steel and concrete, reduces the ratio of width to thickness of the steel plate and is beneficial to give full play of material performance and the improvement of section performance; and the directly stressed U-shaped steel and the directly stressed rectangular steel tube decrease the dimension of sections, eliminate the negative angle of 90 degrees, boost the bearing capacity of the special-shaped column and improve anti-seismic performance. The special-shaped column is simple in manufacture, guarantees the quality of concrete vibrating and casting, is convenient for construction and manufacture and has comparatively good economic benefits.

Description

Multi-chamber type steel tube concrete special-shaped column

Technical field

The invention belongs to building engineering field, be specifically related to a kind of multi-chamber type steel tube concrete special-shaped column.

Background technology

Along with improving constantly of China's output of steel, constant development of economy, to the continuous requirement of environmental type building, steel house has obtained developing rapidly in China.Consider that China is populous, the land resources relative deficiency should develop multilayer and little high-rise steel structure dwelling house.These steel houses adopt framework-support system or framework-concrete shear force wall (core tube) system more, and pillar can adopt steel column, steel core concrete column and combined steel and concrete column, and back two kinds is coupled column.In small sized multiple story building, coupled column is economized steel than steel column, and then also just can reduce construction costs, but therefore the construction of combined steel and concrete column has many steel core concrete columns that adopted in the steel house of having built at present than the steel core concrete column complexity.Although yet the sectional dimension of steel core concrete column compare greatly with reinforced concrete post and reduce, the problem that pillar protrudes metope still exists.In reinforced concrete structure, adopt hetermorphiscal column to make this problem obtain solution, therefore, the notion of hetermorphiscal column in recent years concrete filled steel tube has also been proposed, be that corner post adopts L shaped cross section, side column to adopt T section, center pillar to adopt star section, form by direct fluid concrete in steel pipe.Steel pipe concrete profiled pile not only can avoid pillar to protrude metope, is convenient to space utilization, can also give full play to steel and concrete material property.

At present, the researcher has proposed the section form of multiple steel pipe concrete profiled pile, what propose the earliest is the common steel tube concrete profiled pile, as shown in Figure 1, being welded into chapped pipe by steel plate constitutes to fluid concrete wherein again, but have the negative angle of 90 degree on this cross section, weakened steel and concrete interaction, its composite behaviour is relatively poor.On this basis, researchers proposed some construction measures as be provided with stiffening rib as shown in Figure 2, binding bar is set as shown in Figure 3, or the welding pin waits as shown in Figure 4 and better realizes steel and concrete co-operation.These measures have remedied the defective of common steel tube concrete profiled pile to a certain extent, the cripling that suppresses or slow down steel plate, but above-mentioned construction measure has also increased the construction making and the design difficulty of hetermorphiscal column, is not easy to use.The researcher who also has has proposed to be welded into the concrete filled steel tube combined special-shaped column with two or three rectangular steel pipes, and this cross-sectional configuration is simple, is convenient to construction, but has the bigger limit of flakiness ratio on the cross section, and easily too early flexing has reduced the overall performance of member.In addition, this sectional dimension also has been subjected to the restriction of steel pipe specification, has limited its further application.

Summary of the invention

The objective of the invention is in order to overcome the deficiency of existing steel pipe concrete profiled pile section form, take all factors into consideration each side factors such as mechanical property, construction making, joint structure, design difficulty and economic benefit, a kind of multi-chamber type steel tube concrete special-shaped column is provided, its multiple-chamber type cross section can effectively strengthen steel and concrete interaction, bearing of component and ductility have been improved, be convenient to construction and make, design also simple relatively.

The present invention is a kind of multi-chamber type steel tube concrete special-shaped column, form by U-shaped steel, rectangular steel pipe and the cast concrete in it, the U-shaped steel is welded to each other with rectangular steel pipe is in the same place, the hetermorphiscal column of forming different cross section, whole hetermorphiscal column cross section is separated into multicell by U-shaped steel and rectangular steel pipe, fill concrete in U-shaped steel and the rectangular steel pipe.

Described U-shaped steel is welded by steel plate bending or by steel plate, and described rectangular steel pipe is bent earlier by steel plate and afterwards welds or directly be welded by steel plate.

The invention has the advantages that:

(1) cross section of hetermorphiscal column is divided into multicell and can effectively strengthens steel and concrete interaction, and U-shaped steel and rectangular steel pipe are directly stressed, have reduced sectional dimension, have reduced the flakiness ratio of steel plate, is beneficial to the raising with the cross section performance given full play to of material property;

(2) compare with the common steel tube concrete profiled pile, 90 negative angles of spending have been eliminated after being divided into multicell in the cross section, have improved the bearing capacity of hetermorphiscal column, have improved the anti-seismic performance of hetermorphiscal column;

(3) the present invention is simpler relatively than the steel pipe concrete profiled pile construction making that construction measures such as stiffening rib are set, and has guaranteed concrete vibration, casting quality, is convenient to construction and makes better economic benefit;

(4) compare with the concrete filled steel tube combined special-shaped column, steel do not have overlapping part on the multiple-chamber type cross section, economize steel than the former; The steel plate that width is bigger on the cross section is difficult for too early flexing because of being divided into several sections, makes the compatibility of deformation of concrete and steel, and stress performance is just more reasonable.
