Description
Technical field
The present invention relates to a kind of reinforced column, and in particular to a kind of corrugated steel tube reinforced column, belongs to building
Structural elements.
Background technology
Concrete and shared external load are filled in empty steel pipe, so that it is this new vertical to form steel core concrete column
Primary structure member, because of the interaction of steel pipe and core concrete, can effectively make up the deficiency of two kinds of materials so that steel tube concrete
Soil has the superior mechanical properties such as Compressive Bearing Capacity is high, ductility is good, anti-seismic performance is good, while having easy construction and economy
Can be good the characteristics of, therefore favored by civil engineer, engineer applied is increasingly extensive.Typically steel pipe is used in building structure
Concrete column and the composite frame structure of steel-concrete composite beam formation, but because the cost of combination beam is higher, therefore in engineering
Also frequently with reinforced beam and the frame structure of steel core concrete column formation in practice.But there is beam column in this structure type
Connecting node is complicated, constructional difficulties, the problem of construction quality should not be ensured with stress performance.Therefore, occurring in that steel tube confinement steel
Reinforced concrete post, is characterized in disconnecting steel pipe in beam column node core area so that the steel bar stress in beam can directly pass through
Core space, in order to site operation.But there is also two more distinct issues for this class formation：First, due to joint cores steel
Pipe disconnects, discontinuously so that joint cores are weakened, it is necessary to individually take strengthening measure to realize " strong column and weak beam, node
It is stronger " design principle, but strengthening measure is more difficult and complicated；2nd, due in steel tube confinement armored concrete steel pipe do not connect
Continue, do not directly take on longitudinal force, so thickness of steel pipe is thinner than the steel pipe in common steel tube concrete, but it is special in work progress
The problems such as when being not casting concrete in order to prevent steel pipe off normal, local buckling and running pulp, it is necessary to take corresponding working measure,
So as to add difficulty of construction and cost.The application of this new composite structure system receives certain limitation.
In summary, the frame structure central sill column connected node of existing steel core concrete column-reinforced beam composition by
Power is complicated, constructional difficulties, the problem of construction quality should not be ensured with stress performance, and steel tube confinement reinforced column-steel
The frame structure interior joint core space of Concrete Beam Reinforced composition is difficult to realize the design principle and steel of " strong column and weak beam, node is stronger "
Manage the easy complicated distinct issues of flexing pillar construction.
The content of the invention
The invention aims to solve the frame structure central sill of existing steel core concrete column-reinforced beam composition
Column connected node stress is complicated, constructional difficulties, the problem of construction quality should not be ensured with stress performance, and steel tube confinement reinforcing bar
The frame structure interior joint core space of concrete column-reinforced beam composition is difficult to realize " strong column and weak beam, node is stronger "
Design principle and the easy complicated distinct issues of flexing pillar construction of steel pipe.And then a kind of corrugated steel tube reinforced column is provided.
The technical scheme is that：A kind of corrugated steel tube reinforced column, it includes cylinder and two reinforced concretes
Tu Liang, two reinforced beams are mutually perpendicular to form a plane, and the planar horizontal is located in the cylinder being vertically arranged
On；Cylinder includes opening up four along cylindrical circumferential direction annular array on steel reinforcement cage in corrugated steel tube, concrete and post, corrugated steel tube
Steel reinforcement cage is arranged in corrugated steel tube in corrugated steel tube reserving hole, post, and concreting is in corrugated steel tube；Every reinforcing bar is mixed
Solidifying Tu Liang includes steel reinforcement cage and two groups of guiding steel plates in beam, and two groups of guiding steel plates, which are relatively fixed, to be inserted into two corrugated steel tubes and reserve
In hole, steel reinforcement cage is located on two groups of guiding steel plates and casting concrete in beam.
Further, steel reinforcement cage includes longitudinal steel in stirrup in longitudinal reinforcement in many posts and multiple posts, many posts in post
Muscle circular array is vertically arranged, and longitudinal reinforcement is connected by stirrup in multiple posts for from top to bottom installing in many posts.
Further, steel reinforcement cage includes stirrup in many beam longitudinal reinforcements and multiple beams in beam, and many beam longitudinal reinforcements are in
Rectanglar arrangement, many beam longitudinal reinforcements connect into steel reinforcement cage in beam by stirrup in multiple beams.
Further, being oriented to steel plate includes four blocks of steel plates, and four blocks of steel plates are sequentially fixedly connected with rectangular guiding steel plate.
Further, corrugated steel tube is zinc-plated corrugated steel tube.
The present invention has the following effects that compared with prior art：
1st, the present invention is a kind of simple structure, material cold forming welding, quick construction convenience, low cost, can effectively be kept away
Exempt from construction stage steel pipe partial flexing, and core concrete is bonded reliably with being engaged for corrugated steel tube, and work can be cooperateed with well
Make, while allowing beam insertion at node, it is that can be achieved that " strong post is weak only to mechanically connect stirrup to strengthen joint cores by outside
Beam, node is stronger " design principle so that obtaining a kind of high capacity (can reach the carrying of steel tube confined concrete component
Power level), good ductility, quick construction, the steel core concrete column of good economy performance.
2nd, the present invention using corrugated steel tube as outer steel pipe, because the presence of ripple causes in corrugated steel tube armored concrete
Corrugated steel tube does not carry vertical load directly, primarily serves the effect of constraint core concrete, its operation principle and steel tube confinement
Concrete is identical, so can obtain superior mechanical property using sheet metal, big dimension will be saved relative to concrete filled steel tube
Material, and then reduce 20-30% construction cost.
3rd, ripple of the invention increases the local stability of thin-wall steel tube, can effectively overcome steel tube confined concrete
Easily there is the deficiency of local buckling in middle steel pipe, reduces construction interim measure, and corrugated steel tube is using mechanical cold working, without weldering
Connect, process velocity is fast, steady quality.
4th, fluxion structure of the invention can strengthen the cohesive action of steel pipe and core concrete, so as to slow down or avoid steel
The problem of steel pipe of generally existing comes to nothing with core concrete in pipe concrete column, makes the service behaviour of coupled column more steady
It is fixed.
5th, the present invention can make reinforcing bar without steel pipe is disconnected relative to steel tube confined concrete by opening up hole
Joint cores convenient and reliable can be carried out by beams of concrete insertion by the encryption of bean column node region stirrup on this basis
Reinforcement, and the stabilization of body, the reality of ultimate guarantee " strong column and weak beam, node is stronger " design principle can be ensured in the construction stage
It is existing.
