Abstract
The utility model discloses a novel dual-base-plate rigid connection column base joint of a concrete filled steel tubular column, and belongs to the technical field of architectural structural engineering. The novel dual-base-plate rigid connection column base joint of the concrete filled steel tubular column is characterized that the structure that the concrete filled steel tubular column (1) is in rigid connection with a raft plate foundation (6) is adopted. An upper base plate (2) and a lower base plate (3) are welded on the concrete filled steel tubular column (1), steel bar connection plates (5) are designed to be welded on the upper base plate and the lower base plate according to the condition of base plate steel bars, and studs (4) are welded on the concrete filled steel tubular column (1). The novel dual-base-plate rigid connection column base joint of the concrete filled steel tubular column is high in overall rigidity and strength, clear in force transmission, simple in construction, and capable of effectively reducing the buried depth of column bases, and can be widely applied to various architectural base joint positions of concrete filled steel tubular columns which are large in column base counter-force and small in raft plate thickness.
Description
Technical field
The utility model discloses a kind of novel steel tube concrete column Double bottom plate and rigidly connect foot joint, belong to the structural engineering technical field.
Background technology
Concrete filled steel tube has the intensity height, and ductility is good, endurance, shock resistance, easy superiority such as construction and enjoy favor, uses to get more and more in highrise building.But the research of the node of steel core concrete column is also immature, and at present, steel core concrete column is connected foot joint with raft foundation mainly be that exposed foot joint, flush type foot joint etc. are arranged.Its major defect has: exposed foot joint is mainly used in hinged joint, uses small-scale structure; The flush type foot joint is for heavy construction, and length of embedment is big, and often raft foundation thickness can't satisfy the requirement of length of embedment.In a word, these node power transmissions are not direct, and bearing capacity, rigidity, anti-seismic performance are low, and the simple type of node mechanical property and construction, economy can not be satisfactory to both parties.Therefore, developmental research rational and effective joint form is badly in need of in the fast development of steel core concrete column structural system.
Summary of the invention
The utility model provides a kind of novel steel tube concrete column Double bottom plate to rigidly connect foot joint.
A kind of novel steel tube concrete column Double bottom plate that the utility model proposes rigidly connects foot joint, comprises steel core concrete column (1), upper plate (2), lower shoe (3), peg (4), reinforcing bar junction plate (5) and raft foundation (6).Steel core concrete column (1) welds upper plate (2), welds lower shoe (3) in the steel pipe bottom with upper/lower positions with raft foundation (6) top rebars, at upper plate (3) and lower shoe (4) position welded reinforcement junction plate (5), and in weld stud (4) on the steel pipe and between two base plates.Steel core concrete column (1) cross section can be circular, also can be square, rectangle or the polygonal cross section of remaining silent.Upper plate (2) can be circular according to reinforcement placement, also can be rectangle.Lower shoe (3) can be circular according to reinforcement placement, also can be rectangle.Upper plate (2) can be identical with lower shoe (3) size, also can be different.Raft foundation (6) can be top, bottom double steel bar, also can set up reinforcing bar at the middle part, sets up reinforcing bar junction plate (5) and gets final product setting up reinforcement location.Weld stud (4) on the steel pipe and between two base plates.Unit in charge of construction's actual installation support is born the suspension column deadweight and is kept monolithic stability, and cast is in advance installed with the basis, and suspension column is installed then, assembling reinforcement, cast sole plate.
Compare with traditional flush type node, advantage of the present utility model is:
1) effectively reduced the suspension column length of embedment, economy improves greatly, has avoided because the raft plate is thin excessively, and suspension column is difficult to the problem of effective power transmission;
2) make steel pipe column not be used in and change opening section in the basis into;
3) be conducive to effective transmission of pulling force, reduced the local distortion under the effect of steel pipe post jamb pulling force;
4) node has higher integral rigidity and intensity, and anti-seismic performance is good.
