Description
Technical field
The utility model relates to a kind of new builing structure technical field, is specifically related to a kind of from spacing double-T kernel-angle steel constraining anti-buckling support.
Background technology
Single core unit, delamination material, limiting card and outer steel pipe concrete constraint element that traditional anti-buckling support generally consists of cross or in-line steel plate form.This class supports from great, complicated construction technique, and long construction period, earthquake is difficult to dismounting later, changes; And single core section anti-buckling be supported on every one end while being connected with frame construction and need use eight scabs and two cover bolts, cause end connect long, operative constraint district is short, flexing easily occurs; Limiting card easily loses its spacing effect gradually along with the increase of external force in addition, causes producing relative slippage between constraint element and core cell, affects the stress performance of anti-buckling support; Certainly the delamination material arranging between core cell and constraint element can increase that material expends and man-hour.Although there is thereafter scholar to develop the anti-buckling support of two sleeve dual cores, this kind supports in two sleeves and inserts separately a slice kernel unit, two kernel unit ends after combination are clamped gusset plate and are connected, solved the anti-buckling support of single core and be connected with framework and cause the problems such as connecting length is long, bolt is many, operative constraint district is short, but other problems does not still obtain fine solution.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, improves the stress performance of anti-buckling support, provides a kind of novel from spacing double-T kernel-angle steel constraining anti-buckling support.
The technical solution adopted in the utility model is: a kind of from spacing double-T kernel-angle steel constraining anti-buckling support, comprise kernel stress unit, constraint mechanism and side stay unit;
Described kernel stress unit is with T steel jaggy to combine by two;
Described constraint mechanism comprises steel plate constraint element and angle steel constraint element, and described steel plate constraint element is arranged in the middle of described two T steels, and described angle steel constraint element is four, is separately positioned on four angles of described two T steels;
Described side stay unit is arranged on the side of kernel stress unit, and the shape of the shape of side stay unit and the breach of described T steel matches, and between side stay unit and kernel stress unit, leaves gap.
As preferably, described T steel comprises hot-rolled steel section and soldering group mould assembly steel two classes.
As preferably, described T steel comprises wide width wing edge, the middle edge of a wing, three, narrow edge of a wing type, and kernel stress unit sectional area should calculate depending on Practical Project stressing conditions.
As preferably, the angle steel of described angle steel constraint element comprises hot rolling and clod wash ribbing two classes.
As preferably, the angle steel of described angle steel constraint element comprises equilateral and two types of inequilateral, and in order to guarantee that kernel stress unit can fully surrender, constraint mechanism must have suitable confinement stiffness ratio, and its area is determined through accurate Calculation according to confinement stiffness ratio.
Side stay of the present utility model unit is that in the middle of the two ends cutting from the edge of a wing and the web of former T steel, small part retains and obtains.He and kernel stress unit are integrally formed like this, and side stay unit is reliably connected with constraint element, therefore in whole loading process, between kernel stress unit and constraint element, can not produce relative sliding, make its spacing reliability be improved (this is from limit method, to be different from traditional anti-buckling support separately to establish limiting card part).
The utility model does not need separately to establish delamination material (non-cohesive material), by the gap between kernel stress unit and constraint mechanism arrange to guarantee between them without bonding, its gap length must be determined through accurate Calculation.
The anti-buckling support of the utility model does not need another limiting card and the delamination material established as traditional anti-buckling support, only kernel stress unit and constraint mechanism, jointly consists of.Because constraint mechanism has effectively prevented the pressurized flexing of kernel stress unit, make its pressurized surrender and flexing not, therefore improved Compressive Bearing Capacity, make it draw, press ultimate bearing capacity to equate.
Beneficial effect: the utility model is that all steel type supports.It is lightweight that all steel type supports, and transportation, assembling rapidly, are shortened making, installation procedure and duration, and are conducive to shake rear dismounting, reduce construction costs.
Between the utility model kernel stress unit and constraint mechanism, by side stay unit, form from spacing, do not need separately to establish limiting card.The problem of having avoided the constraint element that uses traditional limiting card mode to bring very easily to slide, has guaranteed the reliability of whole loading process.
Kernel unit of the present utility model adopts double-T design, is not only beneficial to construction, has avoided the problems such as end connecting length is long, bolt is many, operative constraint district is short, has improved the stability bearing capacity of linkage section and the energy dissipation capacity of support.
The utility model does not need separately to establish delamination material, labor and material saving.
The utility model can be the power consumption parts of excellent earthquake resistance and easy accessibility, has good conversion prospect.
