Abstract
The invention relates to a combined steel rib-embedded concrete-filled steel tube column with an irregularly-shaped section, and belongs to the technical field of design of civil engineering building components. The combined column is characterized by comprising two or three steel tubes (1) which are in fillet weld connection, wherein steel ribs (2) are arranged in each steel tube (1); concrete (3) is filled between the steel tubes (1) and the steel ribs (2) for compaction; the cross section of the combined column can be cross-shaped, T-shaped or L-shaped; the steel tubes (1) can be rectangular steel tubes or square steel tubes; the steel ribs (2) can be cross-shaped steel or transverse H-shaped steel. According to the combined column, the two or three steel tubes are in fillet weld connection, and the steel ribs are additionally arranged in the steel tubes, so that the bearing capacity of the combined column is remarkably improved; the combined column has the characteristics of simplicity in welding, accurate forming, convenience for site construction and favorability for improving the working efficiency and the construction quality.
Description
Technical field:
The present invention relates to a kind of odd-shaped cross section concrete filled steel tube coupled column of built-in reinforcing bar, dependent territory wood engineering building unit design field.
Background technology:
Steel core concrete column is used widely in Practical Project with its superior mechanical property and ripe theoretical result.But while adopting steel core concrete column under high pressure, the sectional dimension of pillar is often larger, cylinder is usually outstanding indoor, has not only taken house usable floor area but also be unfavorable for interior decoration and furniture layout.Therefore, Chinese scholars proposes the Design Conception of odd-shaped cross section steel core concrete column.Odd-shaped cross section steel core concrete column mainly contains three kinds of forms at present, and the first is common special-shaped steel pipe concrete post, and the second is the special-shaped steel pipe concrete post of belt restraining pull bar, and the third is the special-shaped steel pipe concrete post with batten plate.
Although above-mentioned three kinds of odd-shaped cross section steel core concrete columns can solve the outstanding indoor problem of cylinder, these three kinds of posts some defects of existence in various degree.Common special-shaped steel pipe concrete post does not also have production line at home and abroad, and in practice of construction, conventionally by welding after steel plate bending or being directly welded, the welding job amount in construction is very large, and the very difficult accurately location of steel plate, and cross sectional shape is wayward.In addition, the disadvantage of common special-shaped steel pipe concrete post is that tube wall steel are very little to core concrete effect of contraction, the inner corner trim of steel pipe deformation failure very easily under vertical uniform load q.In the T shape of belt restraining pull bar, L shaped, ten shape Construction of Steel Pipe Concrete Columns, will on tube wall, hole, position, hole needs accurate measurement can realize pull bar to wearing, and to construction, has proposed very high request, brings very large difficulty of construction, is unfavorable for increasing work efficiency.Manufacturing process with the special-shaped steel pipe concrete post of batten plate is more complicated, and bean column node is difficult for realizing, and the performance of whole bending resistance, shearing resistance and antidetonation need further research.
Summary of the invention:
In order to overcome the deficiencies in the prior art, the object of the present invention is to provide a kind of odd-shaped cross section concrete filled steel tube coupled column of built-in reinforcing bar, by two or three steel pipes, by fillet weld, connected, and in steel pipe, add reinforcing bar, the supporting capacity of coupled column is significantly improved, binding effect is obvious, and anti-seismic performance and refractoriness are good, has that welding is simple, moulding is accurate, site operation is convenient, is beneficial to and increases work efficiency and the feature of workmanship.
The object of the invention is to be achieved through the following technical solutions:
In a kind of structure of odd-shaped cross section concrete filled steel tube coupled column of built-in reinforcing bar, be provided with steel pipe, reinforcing bar, concrete; Coupled column is formed by connecting by fillet weld by two or three steel pipes; At each minute, in steel pipe, be provided with reinforcing bar, the axis of symmetry of the axis of symmetry of reinforcing bar and each minute steel pipe coincides; Between steel pipe and reinforcing bar, concrete filled is closely knit; The cross-sectional form of coupled column can be " ten " font, " T " font or " L " shape; Steel pipe can be rectangular steel pipe, can be rectangular steel tube, can be also " U " shape steel pipe; Reinforcing bar can be " work " Zee bar steel Z, can be also " ten " Zee bar steel Z; The concrete of inside filling out can be ordinary concrete, high-strength concrete, regeneration concrete or self-compacting concrete.
The present invention compared with prior art, by two or three steel pipes, by fillet weld, connected, and in steel pipe, add reinforcing bar, the supporting capacity of coupled column is significantly improved, binding effect is obvious, anti-seismic performance, extraction-resistant behavior, anti-bending strength and refractoriness are good, have that welding is simple, moulding is accurate, site operation is convenient, be beneficial to and increase work efficiency and the feature of workmanship.
