Abstract
The invention discloses a self-limiting double-T-shaped core-angle steel constraint buckling-restrained brace, which comprises a core stress unit, a constraint mechanism and a side brace unit, wherein the core stress unit is arranged on the inner wall of the brace; the inner core stress unit is formed by combining two T-shaped steels with notches; the restraining mechanism comprises steel plate restraining units and angle steel restraining units, the steel plate restraining units are arranged between the two T-shaped steels, and the number of the angle steel restraining units is four, and the four angle steel restraining units are respectively arranged at four corners of the two T-shaped steels; the side supporting units are arranged on the side faces of the inner core stress units, the shapes of the side supporting units are matched with those of the notches of the T-shaped steel, and gaps are reserved between the side supporting units and the inner core stress units. The constraint mechanism effectively prevents the stress buckling of the stress unit of the inner core, so that the stress buckling of the stress unit of the inner core is avoided, and the stress buckling is avoided, thereby improving the compression-resistant bearing capacity and enabling the tensile and compression limit bearing capacities of the stress unit of the inner core to be equal.
Description
Technical field
The present invention relates to a kind of new builing structure technical field, be specifically related to a kind of from spacing double-T kernel-angle steel constraining anti-buckling support.
Background technology
The single core unit that traditional anti-buckling support generally consists of cross or in-line steel plate, delamination material, limiting card and outer steel pipe concrete constraint element 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 each end while being connected with frame construction and need use eight scabs and two cover bolts, cause end connect long, the 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 between constraint element and core cell producing relative slippage, affects the stress performance of anti-buckling support; Certainly the delamination material arranged between core cell and constraint element can increase that material expends and man-hour.Although there is thereafter the 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, the operative constraint district is short, but other problems does not still obtain fine solution.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, improve the stress performance of anti-buckling support, provide a kind of novel from spacing double-T kernel-angle steel constraining anti-buckling support.
The technical solution used in the present invention 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, three, the ,Zhai edge of a wing, middle edge of a wing type, and kernel stress unit sectional area should calculate depending on the 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, in order to guarantee the kernel stress unit, can fully surrender, and 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 invention unit is that small part retains and obtains in the middle of the edge of a wing of former T steel and the cutting of the two ends web.He and kernel stress unit are integrally formed like this, and the side stay unit reliably is connected with constraint element, therefore can not produce relative sliding between kernel stress unit and constraint element in whole loading process, make its spacing reliability be improved (this is to be different from traditional anti-buckling support from limit method separately to establish the limiting card part).
The present invention does not need separately to establish delamination material (non-cohesive material), by the gap between kernel stress unit and constraint mechanism, arranges to guarantee the nothing bonding between them, and its gap length must be determined through accurate Calculation.
The anti-buckling support of the present invention 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 present invention 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.
Form from spacing by the side stay unit between kernel stress unit of the present invention and constraint mechanism, do not need separately to establish limiting card.The problem that the constraint element of having avoided using traditional limiting card mode to bring very easily slides, guaranteed the reliability of whole loading process.
Kernel unit of the present invention adopts the double-T design, not only is beneficial to construction, has avoided the problems such as the end connecting length is long, bolt is many, the operative constraint district is short, has improved the stability bearing capacity of linkage section and the energy dissipation capacity of support.
The present invention does not need separately to establish delamination material, labor and material saving.
The present invention can be the power consumption parts of excellent earthquake resistance and easy accessibility, has good conversion prospect.
