Description
Technical field
The utility model is related to building structure technology field, more particularly to a kind of rectangle steel using rib pull bar constraint of perforating
Pipe concrete column.
Background technology
Rectangular steel-tube concrete column has the incomparable distinctive feature of circular steel tube concrete post, such as steel in engineer applied
The pipe connection with beam easy to make is easily processed, easy construction, be easy to meet the relative development in architectural plane requirement, section and inertia
Square is big, the advantages of be suitable as bending component, had attracted increasing attention in engineering practice.
For concrete-filled rectangular steel tube, because steel pipe is concentrated mainly on corner to core concrete effect of contraction, on four sides
Middle part effect of contraction there's almost no, so steel pipe is much smaller than round steel pipe coagulation to the overall effect of restraint of core concrete
Soil, its bearing capacity is much lower compared with circular steel tube concrete.Rectangular steel pipe section side long is weak to the effect of contraction of core concrete
In short side, and steel pipe side shorter edge long is more easy to local buckling.
The lateral rigidity of rectangular steel-tube concrete column steel plate is effectively improved, delays the bonding between steel pipe walls and concrete
Sliding, can lift the ability and the effect of contraction to core concrete of its resistance local buckling, reinforcing steel pipe and concrete
Integraty, so as to improve bearing capacity and ductility.
Rectangular Cft Columns With Binding Bars post is using the horizontal water of setting on longitudinal cross section at spacing intervals
The design form of flat binding bar.The advantage of this form is bar connection, and bilateral greatly strengthen to core coagulation to drawing
The hoop constraint of soil, so that it is constraint weak spot to improve between the bearing capacity of steel core concrete column, but binding bar vertical, horizontal,
Avoid the generation of these position local bucklings, operative constraint of the comprehensive formation to core concrete, it is necessary to which encryption constraint is drawn
Bar arranges that drilling is excessive, and pull bar consumption is big.
Another way is that the form for setting ribbed stiffener in steel pipe periphery midpoint is strengthened concrete-filled rectangular steel tube.It is this
The outer deformability of form ribbed stiffener containment surfaces is weak, and the loading later stage is easily caused disengaging with concrete binding failure, to delay or preventing
Only the deformation of middle side edge is, it is necessary to larger stiffness ratio of stiffener to panel, consumes steel more.And, ribbed stiffener fails to be formed to core
The hoop constraint of concrete, lateral confinement power is weaker than being connected to drawing for binding bar, although can to a certain extent delay local bending
Bent generation, but it is limited to improve the bearing capacity of rectangular steel-tube concrete column.
The content of the invention
For the shortcoming and deficiency that overcome prior art to exist, the intensity of steel is made full use of, delay or avoid peripheral steel
The longitudinally, laterally local buckling problem of plate, forms the one of the hoop constraint to core concrete, enhancing steel pipe and concrete
Property, so that the axle pressure of rectangular steel-tube concrete column, bias bearing capacity, anti-seismic performance are improved, the utility model proposes one
The mentality of designing and construction method for improving rectangular steel-tube concrete column lateral rigidity are planted, that is, rib pull bar constraint rectangular steel pipe of perforating is mixed
Solidifying earth pillar.
Perforation rib pull bar constraint rectangular steel-tube concrete column integraty reinforcement technique is by the perforate on ribbed stiffener, constraint
Pull bar is perforated and mistake, connection（Welding or bolt connection）In in steel pipe walls, effective effect of contraction is formed to perforate ribbed stiffener, entered
And slow down the local buckling of steel pipe walls.This design constrains the point-like of binding bar in binding bar rectangular steel-tube concrete column
Become the wire constraint of ribbed stiffener, be not required to encrypt binding bar, excessive perforate can be prevented effectively from steel pipe walls.With second side
Formula is compared, and the setting of binding bar forms larger hoop constraint effect to steel pipe walls, it is not necessary to firm using larger floor
Degree ratio, can effectively delay the bond-slip between steel pipe walls and concrete.
The utility model is adopted the following technical scheme that：
Perforation rib pull bar constraint rectangular steel-tube concrete column, including rectangular steel pipe, concrete, ribbed stiffener, pull bar.It is described to add
Strength rib is strip-form steel plate, and its thickness is identical with thickness of steel pipe.The ribbed stiffener upper connecting rod answers perforate, the size in hole through position
Pull bar be able to be passed through.The ribbed stiffener is evenly arranged on steel pipe pars intramuralis periphery, is connected using welding method perpendicular to steel pipe walls
Connect.The pull bar uses common pull bar or reinforcing bar, passes perpendicularly through the side long of rectangular steel pipe, and short side is handed over along pillar height with appropriate spacing
Mistake arrangement.The tie rod end is such as perforate plug welding mode, second from welding with the first connected mode of steel pipe walls
Connected mode is to carry out mantle fiber treatment with thread cutter for steel bar in tie rod end, is connected by screw bolts through steel pipe walls tapping.
The beneficial effects of the utility model：
(1) perforate ribbed stiffener and binding bar are combined closely, and few steel using amount is increased do not increase difficulty of construction, shadow again
In the case of ringing construction speed, the effect of contraction of continuous effective is formed in whole height in four middle side edges of steel pipe walls, improved
Side constraint ability, delays or avoids the sliding between steel pipe and concrete, and the bullet between binding bar is slowed down to greatest extent
Plastic buckling, makes rectangular steel pipe significantly be strengthened with the integraty of concrete.(2) premise of structural safety is being met
Under, can to large extent with relatively thin steel plate thickness, less rib width of putting more energy into, the integraty of enhancing steel pipe and concrete is real
Intensity now higher, rigidity and ductility.(3) restraining force for wearing pull bar will be uniformly transferred to steel plate by ribbed stiffener, make pull bar
Point-like constraint be changed into wire constraint, it is to avoid stress concentration, steel pipe to the effect of contraction of core concrete relative to simple plus
If the rectangular steel-tube concrete column of binding bar is more continuous and uniform, relative to the rectangular steel pipe coagulation for adding ribbed stiffener merely
Earth pillar more can effectively reduce the integraty of steel quantity consumption, enhancing steel pipe and concrete., along along short transverse, ribbed stiffener is along section for pull bar
Length direction is split steel plate, reduces the depth-width ratio and flakiness ratio of steel plate, so that its half buckle wavelength subtracts significantly
It is small.For peripheral steel plate, pull bar constraint ribbed stiffener provides strong sidewise restraint, prevents the flexing that steel plate is too early, favorably
In its intensity of performance, meanwhile, steel plate constrains core concrete again with pull bar as fulcrum with its bending rigidity, makes concrete multi-shaft
It is pressurized and improves its intensity.(5) component is easy to be connected with other steel members of surrounding, can give full play to steel plate and concrete
Two kinds of mechanical properties of material, not only improve and undertake vertical load, are conducive to undertaking horizontal loading again.
