Abstract
The invention discloses a sleeve restraint anti-buckling support provided with staggered pyramid-shaped energy dissipation units. The sleeve restraint anti-buckling support provided with the staggered pyramid-shaped energy dissipation units is characterized in that the sleeve restraint anti-buckling support is composed of end restraint sections, energy dissipation sections and a sleeve, and the two ends are connected with beam or column components or joints in a whole through bolts, so that the purpose of increasing the resistant-lateral rigidity of a component is achieved. By the adoption of the sleeve restraint anti-buckling support provided with the staggered pyramid-shaped energy dissipation units, under the small shock action, the sleeve restraint anti-buckling support can be kept elastic; and under the medium or great shock action, the energy dissipation sections are switched to the buckling stage, and a damper effect can be achieved through the good hysteretic energy dissipation performance of the energy dissipation sections. The sleeve restraint anti-buckling support provided with the staggered pyramid-shaped energy dissipation units can be prefabricated in a factory, the quality of the component is guaranteed, the field construction workload is reduced, energy is saved, and environmental friendliness is achieved.
Description
Technical field
The invention belongs to building structure technology field, particularly relate to a kind of set with staggered pyramid power consumption unit
Pipe constraining anti-buckling supports, it is adaptable to the steel construction of band buckling restrained brace or xoncrete structure.
Background technology
During steel construction or reinforced concrete structure use, common support pressurized can produce flexing phenomenon, when propping up
After support compressive buckling, rigidity and bearing capacity drastically reduce.Under earthquake or wind action, the internal force of support is in pressurized and tension two
Back and forth change under the state of kind.When support is gradually faded to tension state by the state of buckling, internal force and the rigidity of support are close to
Zero.Thus common support Hysteresis Behavior under course under cyclic loading is poor.For solving common support compressive buckling and hysteresis
Can the problem of difference, supporting the outside sleeve pipe that arranges, the compressive buckling that constraint supports, constitute buckling restrained brace only central layer and other
Component connects, and suffered load is all undertaken by central layer, and outer sleeve and packing material only retrain central layer compressive buckling, makes central layer exist
Tension and all being entered by pressure is surrendered, thus, the Hysteresis Behavior of buckling restrained brace is excellent.Buckling restrained brace on the one hand can
To avoid the defect of common support tension and compression bearing capacity significant difference, on the other hand there is the energy dissipation capacity of metal damper, permissible
Serve as " electric fuse " in the structure so that agent structure is substantially in elastic range.Therefore, the application of buckling restrained brace,
Traditional support frame anti-seismic performance under middle shake and big shake can be improved comprehensively.
Summary of the invention
Goal of the invention: owing to existing constraining anti-buckling is supported under course under cyclic loading, be connected with buckling restrained brace

Number m is the integer more than or equal to 4；Described pyramid subelement is made up of four blocks of identical isosceles triangle plates, four etc.
Lumbar triangle shape plate conllinear two-by-two also intersects at a summit, and the face that this summit and isosceles triangle plate base are formed is not put down at one
In face；In described pyramid power consumption unit, the summit of all pyramid subelements on each is at isosceles triangle plate
Outside and the inner side in the face that base is formed are alternately arranged.
Described end restraint section is made up of the connecting plate that the components such as regular polygon steel plate, T-shaped short girder steel and beam column are reserved,
Regular polygon Plate Welding is in power consumption section end, and two T-shaped short girder steels are connected with regular polygon Plate Welding, and connecting plate is clipped in two
In the middle of the T-shaped short girder steel of root, connecting plate is connected with T-shaped short girder steel high-strength bolt, and the limit number of described regular polygon steel plate is also
m。
Described sleeve pipe is made up of the hollow steel pipe of equilateral polygon section.One layer of soap-free emulsion polymeization is covered inflatable inside described sleeve pipe
Material, fills mortar at soap-free emulsion polymeization expandable material outside power consumption section.
Beneficial effect:
A kind of sleeve pipe constraining anti-buckling with staggered pyramid power consumption unit of the present invention supports, by end restraint section, power consumption
Section and sleeve pipe are constituted.The sleeve pipe constraining anti-buckling with staggered pyramid power consumption unit is used to support, owing to tension and compression are uneven
Coefficient is less, is conducive to protecting component or the bean column nodes such as beam column under geological process.Power consumption section is consumed energy by multiple pyramids
Unit forms, and pyramid power consumption unit is by the folding line pre-set, and folding line is the intersecting lens of adjacent two triangular plates, makes
It is supported under geological process, at the folding line pre-set, bigger strain can occur thus form yield line, reach to dissipate
The purpose of seismic energy.The present invention can have only to the built-in fitting with components such as bolt and beam columns even in factory process to scene
Connect, both ensure that component quality, reduce again the wet trade workload at scene, energy-conserving and environment-protective.There is the power consumption of staggered pyramid
The sleeve pipe constraining anti-buckling of unit supports the flexible arrangement both with the anti-buckling support of general restriction, and can more effectively dissipate earthquake
The advantages such as energy, can solve again the component that is connected with buckling restrained brace or the problem such as joints is bigger, have good
