Description

A kind of concrete filled steel tube combined special-shaped column of anti-buckling cant timber connection
Technical field
It is to be related to a kind of anti-buckling cant timber specifically the present invention relates to a kind of Special-Shaped Column in building structure The concrete filled steel tube combined special-shaped column of connection..
Background technology
Present concrete filled steel tube is that fill concrete is constituted in steel pipe, and it utilizes two kinds of materials of steel pipe and concrete The effect of contraction of interaction in loading process, i.e. steel pipe to core concrete so that concrete is in three dimension stress State, so that concrete strength is improved, ductility is improved;At the same time, due to the presence of concrete, can delay or Avoid the steel pipe local buckling occurs to early, it is ensured that steel performance gives full play to.In the work progress of concrete filled steel tube, steel pipe Formwork cost can be saved as the formwork for placing of its core concrete, compared with armored concrete, accelerate construction speed Degree.
The proposition of concrete filled steel tube combined special-shaped column has benefited from that its sectional dimension is small, and post is built with accomplish wide with body of wall so as to avoid Build the problem that salient angle influence house usable floor area and house fitting-up occurs in corner.In past several years, concrete filled steel tube combination is different Shape post has obtained certain development, is also applied in some Practical Projects.Widely used at present is batten plate formula Connection or the steel pipe concrete profiled pile of lacing formula connection, the defect of these Special-Shaped Columns are that horizontal floor is more, welding difficulty It is larger, and lateral resistance behavior is limited, the lateral resistance behavior for being difficult to meet skyscraper in requirements for fortification against earthquake area higher will Ask, limit the application and development of concrete filled steel tube combined special-shaped column.
In order to solve, the horizontal floor of steel pipe concrete profiled pile is more, welding difficulty is larger, and lateral resistance behavior is limited, The problems such as requirements for fortification against earthquake area higher is difficult to the lateral resistance behavior requirement for meeting skyscraper, it is necessary to seek one kind can Meet lateral resistance requirement, the scene steel pipe concrete profiled pile form that energy Fast Installation is constructed again.
The content of the invention
The invention aims to overcome deficiency of the prior art, there is provided a kind of lateral resistance behavior is excellent, and is beneficial to Process the concrete filled steel tube combined special-shaped column of the anti-buckling cant timber connection installed.
The purpose of the present invention is achieved through the following technical solutions:
A kind of concrete filled steel tube combined special-shaped column of anti-buckling cant timber connection, by an intermediate rectangular steel pipe and at least two The upper and lower ends of root periphery rectangular steel pipe composition, the intermediate rectangular steel pipe and peripheral rectangular steel pipe pass through connecting plate phase respectively Even, the connecting plate vertical is set and perpendicular with the side of the intermediate rectangular steel pipe and peripheral rectangular steel pipe, the connection Horizontal floor is provided between plate at equal intervals, it is oblique between the horizontal floor to be provided with anti-buckling floor, the intermediate rectangular Concrete structure has been poured in steel pipe and peripheral rectangular steel pipe.
The Special-Shaped Column is different for L-shaped by cross section that the peripheral rectangular steel pipe of an intermediate rectangular steel pipe and two is constituted Shape post.
The Special-Shaped Column is different for T-shaped by cross section that the peripheral rectangular steel pipe of an intermediate rectangular steel pipe and three is constituted Shape post.
The Special-Shaped Column is cross by the cross section that the peripheral rectangular steel pipe of an intermediate rectangular steel pipe and four is constituted Special-Shaped Column.
The connecting plate, horizontal floor and anti-buckling floor are constituted by steel plate.
Compared with prior art, the beneficial effect that technical scheme is brought is:
(1) sectional dimension is small and flexible arrangement, can be hidden in construction wall from without dew post, is suitable for steel structure of housing pair The requirement in space, increases interior architecture usable floor area.The important feature system of engineer applied, steel pipe concrete profiled pile are turned into Structure solves the buildings such as daylighting is high, divulge information, building structure inner space utilization rate is high, economize on resources and uses functional requirement.
(2) workload of weld seam quantity and on-the-spot welding is reduced, speed of application is accelerated, construction costs is reduced.Compare In the steel pipe concrete profiled pile that batten plate formula or lacing formula are connected, the horizontal floor of the Special-Shaped Column is few, so that weld seam quantity is small, construction Speed is fast, while reducing the influence of residual stress and residual deformation that welding brings, reduces the initial imperfection of Special-Shaped Column, increases The strong overall performance of Special-Shaped Column.
(3) angularly disposed anti-buckling floor can be surrendered under horizontal force action prior to main body steel pipe, so that the level that dissipates Power, main body steel pipe continues to carry, and with excellent lateral resistance behavior, can be widely used for requirements for fortification against earthquake skyscraper high In, in coming earthquake, the quality time can be striven for for people life property safety.
