Abstract
The invention discloses a kind of casing constraining anti-buckling supports with duplex pyramid type energy consumption unit, it is characterized by: being made of end restraint section, energy consumption section and casing three parts, both ends connect that shape is integral with beam, column component or node by bolt, to achieve the purpose that the anti-side rigidity of increase component.Using the casing constraining anti-buckling support with duplex pyramid type energy consumption unit, under small shake effect, this buckling restrained brace keeps elasticity, in middle shake or big shake effect, energy consumption section enters yielding stage, and good hysteretic energy performance can play the effect of damper again.Casing constraining anti-buckling with duplex pyramid type energy consumption unit supports the molding that can be prefabricated in the factory, and ensure that component quality, reduces Contraction in Site workload, energy conservation and environmental protection.
Description
Technical field
The invention belongs to building structure technology fields, more particularly to a kind of set with duplex pyramid type energy consumption unit
Pipe constraining anti-buckling support, suitable for steel construction or concrete structure with buckling restrained brace.
Background technique
In steel construction or reinforced concrete structure use process, common support compression can generate buckling phenomenon, work as branch
After supportting compressive buckling, rigidity and bearing capacity are drastically reduced.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
Can difference problem, casing is set outside support, constrains the compressive buckling of support, constitute buckling restrained brace only core plate and other
Component connection, suffered load are 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
It, can be on the other hand with the energy dissipation capacity of metal damper to avoid the defect of common support tension and compression bearing capacity significant difference
" fuse " is served as in the structure, so that main 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.
Summary of the invention

On the common support of system, a kind of casing constraining anti-buckling support with duplex pyramid type energy consumption unit is formed, is engineering knot
Preferential selection when constraining anti-buckling support is selected in structure.
Technical solution: to achieve the above object, the technical solution adopted by the present invention are as follows:
A kind of casing constraining anti-buckling support with duplex pyramid type energy consumption unit, by end restraint section, energy consumption section
It is formed with casing, the end restraint section is located at the both ends of the energy consumption section, and described sleeve pipe covers in the energy consumption section, feature
Be: energy consumption section is by least one positive pyramid energy consumption unit and a reversed pyramid energy consumption unit along support
Axis direction alternately forms；The positive pyramid energy consumption unit and reversed pyramid energy consumption unit is by n phase
Same pyramid subelement is circumferentially arranged successively the space body to form that a section is regular polygon；The pyramid
The number n of subelement be even number more than or equal to 6 and be m multiple；The number of edges m of the regular polygon is whole more than or equal to 4
Number；The pyramid subelement is by isosceles triangle board group four identical pieces of at four isosceles triangle plates are conllinear two-by-two
And intersect at a vertex, face composed by the vertex and isosceles triangle board bottom side not in a plane, so four pieces of isosceles
Triangular plate forms a Pyramid；The top of all pyramid subelements in the positive pyramid energy consumption unit
Point is in the outside of regular polygon；The vertex of all pyramid subelements is just more in the reversed pyramid energy consumption unit
The inside of side shape.
The end restraint section is made of the connecting plate that the components such as regular polygon steel plate, the short girder steel of T-type and beam column are reserved,
Regular polygon steel plate is welded on energy consumption section end, and two short girder steels of T-type and regular polygon steel plate are welded to connect, and connecting plate is clipped in two
Among the short girder steel of root T-type, connecting plate is connect with the short girder steel of T-type with high-strength bolt, and the number of edges of the regular polygon steel plate is also
m。
Described sleeve pipe is made of the hollow steel pipe of equilateral polygon section.It is inflatable that one layer of soap-free emulsion polymeization is covered on the inside of described sleeve pipe
Material fills mortar on the outside of soap-free emulsion polymeization expandable material and energy consumption section.
The utility model has the advantages that
The present invention it is a kind of with duplex pyramid type energy consumption unit casing constraining anti-buckling support, by end restraint section,
The section that consumes energy and casing are constituted.Using the casing constraining anti-buckling support with duplex pyramid type energy consumption unit, not due to tension and compression
Coefficient of balance 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
Consume energy unit composition, and intersecting lens of the pyramid energy consumption unit two-by-two between triangular plate forms pre-set folding line, described
Folding line indicate the intersecting lens of two neighboring triangular plate, make to be supported under geological process, can be sent out at pre-set folding line
Raw biggish strain achievees the purpose that dissipation seismic energy to form yield line.The present invention can be in factory process, to now
Field only needs the built-in fitting for using the components such as bolt and beam column to connect, and not only ensure that component quality, but also reduces the wet construction at scene
Workload, energy conservation and environmental protection.Casing constraining anti-buckling support with duplex pyramid type energy consumption unit was both anti-with general restriction
The flexible arrangement of buckling support, can more effectively dissipate seismic energy the advantages that, and can solve and be connected with buckling restrained brace
The problems such as component or larger joints for connecing, has good Popularizing of A.
