Abstract
The invention discloses a kind of ends, and there is the buckling of duplex pyramid type energy consumption unit to control support, it is characterised in that：It is made of end restraint section, energy consumption section and support flat segments three parts, both ends connect that shape is integral by bolt with beam, column component or node, to achieve the purpose that the anti-side rigidity of increase component.Using end there is the buckling of duplex pyramid type energy consumption unit to control support, under small shake effect, this buckling restrained brace keeps elasticity, in middle shake or big shake effect, buckling restrained brace enters yielding stage, and good hysteretic energy performance can play the effect of damper again.Compared with traditional buckling restrained brace, the present invention avoids in manufacture craft and adds the processes such as sleeve and grouting in conventional fabrication process outside core dissipative member, easy to make；The support can be prefabricated in the factory molding, ensure that component quality, reduce Contraction in Site workload, energy conservation and environmental protection.
Description
Technical field
The invention belongs to building structure technology fields, have duplex pyramid type energy consumption unit more particularly to a kind of end
Buckling control support, be suitable for steel construction or concrete structure with buckling restrained brace.
Background technology
During steel construction or reinforced concrete structure use, common support compression will produce buckling phenomenon, work as branch
After supportting compressive buckling, rigidity and bearing capacity drastically reduce.Under earthquake or wind action, the internal force of support is being pressurized and tension two
Back and forth change under kind state.When support gradually fades to tension state by the state of buckling, the internal force and rigidity of support are close to
Zero.Thus common support Hysteresis Behavior under course under cyclic loading is poor.To solve common support compressive buckling and hysteresis
The problem of energy difference, is arranged casing outside support, constrains the compressive buckling of support, constitutes buckling restrained brace only core plate and other
Component connects, and suffered load is all undertaken by core plate, and outer sleeve and packing material only constrain core plate compressive buckling, and core plate is made to exist
Tension and by pressure can enter surrender, 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, the on the other hand energy dissipation capacity with metal damper can be with
It serves as in the structure " fuse " so that agent structure is substantially in elastic range.Therefore, the application of buckling restrained brace,
Anti-seismic performance of traditional braced frame under middle shake and big shake can be improved comprehensively.But traditional buckling restrained brace is usually adopted
With steel and coagulation local soil type at restraining tube, it is high to lead to make precision prescribed, big from great and difficulty of construction, to core cell sheet
Body makes it promote and is very limited with use scope there are larger additional load.
Invention content
Goal of the invention：Since existing buckling restrained brace has the compositions such as core plate, outer sleeve and packing material, manufacture craft multiple
It is miscellaneous, and the component or joints that are connected with buckling restrained brace are larger；Of the existing technology, this hair in order to overcome the problems, such as
It is bright to introduce on initial imperfection to traditional common support, form a kind of buckling of the end with duplex pyramid type energy consumption unit
Control support is preferential selection when selecting buckling restrained brace in engineering structure.
Technical solution：To achieve the above object, the technical solution adopted by the present invention is：
A kind of end has the buckling control support of duplex pyramid type energy consumption unit, including confinement section and energy consumption section,

The other end setting confinement section, energy consumption section is by least one positive pyramid energy consumption unit and a reversed pyramid
The unit that consumes energy alternately is formed along the axis direction of support；The positive pyramid energy consumption unit and reversed pyramid consumption
Energy unit is circumferentially to be arranged in order to form the space that a section is regular polygon by n identical pyramid subelements
Body；The number n of the pyramid subelement be even number more than or equal to 6 and be m multiple；The number of edges of the regular polygon
M is the integer more than or equal to 4；The pyramid subelement is by isosceles triangle board group four identical pieces of at four isosceles
Triangular plate is conllinear two-by-two and intersects at a vertex, and the face which is formed with isosceles triangle board bottom side is not in a plane
It is interior；The vertex of all pyramid subelements is in the outside of regular polygon in the positive pyramid energy consumption unit；It is described
Reversed pyramid energy consumption unit in all pyramid subelements vertex in the inside of regular polygon.
The end restraint section is made of regular polygon steel plate, the short girder steel of T-type and connecting plate, and regular polygon steel plate is welded on
The section that consumes energy end, two short girder steels of T-type are welded to connect with regular polygon steel plate, and connecting plate is clipped among two short girder steels of T-type, even
Fishplate bar is connect with the short girder steel of T-type with high-strength bolt, and the number of edges of the steel plate is also m.
The support flat segments are made of the steel pipe that section is regular polygon and regular polygon steel plate, the weldering of regular polygon steel plate
It is connected on the end of the steel pipe of equilateral polygon section, energy consumption section is welded to connect with regular polygon steel plate, the number of edges of the steel tube section
For m.
Advantageous effect：
A kind of end of the present invention has the buckling control support of duplex pyramid type energy consumption unit, by end restraint section, consumption
It can section and support flat segments composition.Using end there is the buckling of duplex pyramid type energy consumption unit to control support, due to tension and compression
Unbalance factor is smaller, is conducive to protect components or the bean column nodes such as beam column under geological process.The section that consumes energy is by multiple pyramids
Type consumes energy unit composition, and intersecting lens of the pyramid energy consumption unit two-by-two between triangular plate forms pre-set folding line, make
It is supported under geological process, larger strain can occur at pre-set folding line to form yield line, reach dissipation
The purpose of seismic energy.The present invention avoids outside core dissipative member jacketed cylinder, in sleeve and core in manufacture craft
The processes such as grouting, simplify processing and making process, reduce project cost between dissipative member.And the present invention can be in factory
Processing only needs the built-in fitting for using the components such as bolt and beam column to connect, not only ensure that component quality, but also reduce scene to scene
Wet construction workload, energy conservation and environmental protection.Buckling control support of the end with duplex pyramid type energy consumption unit is both with general
The advantages that flexible arrangement of buckling restrained brace, good energy-dissipating property, but can by pre-set initial imperfection shape,
The buckling form for controlling support prevents component from complete buckling occurs to early, while can add to avoid outside core dissipative member
The processes such as upper bush and grouting effectively simplify manufacturing procedure, have good Popularizing of A.
