Abstract
This utility model one teeprofile confined concrete models, is mainly made up of steel pipe, reinforcing bar and concrete.Steel pipe is the T-shaped around concrete, indulges muscle, stirrup and forms reinforcing bar to drawing reinforcing bar ribbed stiffener solidity to connect, and the reinforcing bar that landing tee is put is positioned at the center of shape steel pipe, coaxial with teeprofile, and interior reinforcing bar and steel-pipe welding or bolt connect.Provided the benefit that by technique scheme efficiently solve solution shaped rc columns poor seismic behavior, low bearing capacity, construction complicated and traditional special-shaped steel pipe concrete post structure is complicated, steel using amount big, high cost problem.
Description
Technical field
This utility model relates to building structural element, particularly relates to a kind of teeprofile confined concrete models.
Background technology
In the last few years, special-shaped column structure was more and more applied in some case histories.Traditional Special-Shaped Column many employings armored concrete, is promoting and is exposing some problems in practical engineering application: very sensitive to the directivity of horizontal loads, the strength of materials can not make full use of；Node arrangement of reinforcement is more, cast in situs difficulty.Therefore, the building height of Special shaped R.C. frame is severely limited, and shaped rc columns poor seismic behavior, low bearing capacity, construction complicated and traditional special-shaped steel pipe concrete post structure is complicated, steel using amount is big, high cost problem.Which greatly limits the promotion and application of Special-Shaped Column.
Utility model content
The purpose of this utility model is to provide a kind of teeprofile confined concrete models, can not make full use of solving the strength of materials of prior art, cast in situs difficult problem.
The technical solution of the utility model is: a kind of teeprofile confined concrete models, is mainly made up of reinforcing bar, steel pipe and concrete.Steel pipe is the T-shaped around concrete, indulges muscle, stirrup and forms reinforcing bar to drawing reinforcing bar ribbed stiffener solidity to connect, and the reinforcing bar that landing tee is put is positioned at the center of shape steel pipe, coaxial with teeprofile, and interior reinforcing bar and steel-pipe welding connect.
The beneficial effects of the utility model are: a kind of teeprofile confined concrete models, simple in construction, after ribbed stiffener is set, the steel pipe effect of contraction to core concrete can be effectively improved, postpone or avoid steel pipe to occur cripling to cause component premature failure before stress reaches yield strength.Reasonable disposition reinforcing bar, effectively reduces amount of reinforcement, reduces cost, and node arrangement of reinforcement reduces, and not only reduces cast in situs difficulty, and improves strength of materials utilization rate.So that the bearing capacity of steel core concrete column, rigidity, shock resistance and ductility are greatly improved.

Fig. 2 is that ribbed stiffener of the present utility model arranges schematic diagram；
1-indulges muscle；2-concrete；3-stirrup；4-steel pipe；5-is to drawing reinforcing bar ribbed stiffener.
Detailed description of the invention
As depicted in figs. 1 and 2, this utility model teeprofile confined concrete models is mainly by concrete, vertical muscle, stirrup, steel pipe and to drawing reinforcing bar ribbed stiffener to form, steel pipe is the T-shaped around concrete, indulge muscle, stirrup and form reinforcing bar to drawing reinforcing bar ribbed stiffener solidity to connect, the reinforcing bar that landing tee is put is positioned at the center of shape steel pipe, coaxial with teeprofile, interior reinforcing bar and steel-pipe welding connect.
Steel pipe 4 end of general T-shaped concrete-filled steel tube specimen is disconnected by teeprofile confined concrete models of putting more energy into, it is made not undertake xial feed, sidewise restraint is provided to concrete 2, steel pipe 4 is internal to be arranged drawing reinforcing bar 5, prevent steel pipe 4 at inner corner trim from disengaging with concrete 2, meanwhile, arrange as shown in Figure 2 at cross-sectional internal configuration longitudinal reinforcement 1 and stirrup 3, bar gauge and layout position ribbed stiffener 5.Stirrup 3 spacing is near nodal (in the range of distance bean column node 300mm) encryption, and spacing is 100mm, and beyond node area, stirrup spacing is 150mm.Simultaneously to drawing reinforcing bar ribbed stiffener 5 also to encrypt near nodal (in the range of distance bean column node 300mm), spacing is 100mm, and node area is with adding rib 5 obligatory point spacing as 200mm.
Certainly, technique scheme is preferred forms of the present utility model, and any improvement made under without departing from spirit background of the present utility model, within all falling within protection domain of the present utility model.
Claims (1)
1. a teeprofile confined concrete models, by concrete, vertical muscle, stirrup, steel pipe and to drawing reinforcing bar ribbed stiffener to form, it is characterized in that: steel pipe is the T-shaped around concrete, indulge muscle, stirrup and form reinforcing bar to drawing reinforcing bar ribbed stiffener solidity to connect, the reinforcing bar that landing tee is put is positioned at the center of shape steel pipe, coaxial with teeprofile, interior reinforcing bar and steel-pipe welding connect.
