Abstract
The invention discloses a kind of casing constraining anti-buckling supports with staggeredly pyramid energy consumption unit, it is characterised in that：It is made of end restraint section, energy consumption section and casing 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 the casing constraining anti-buckling support for the unit that consumes energy with staggeredly pyramid, 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 staggeredly pyramid 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 staggeredly pyramid energy consumption unit
Pipe constraining anti-buckling supports, and is 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.
Invention content
Goal of the invention：Since existing constraining anti-buckling is supported under course under cyclic loading, it is connected with buckling restrained brace

On the common support of system, a kind of casing constraining anti-buckling support with staggeredly pyramid 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 is：
A kind of casing constraining anti-buckling support with staggeredly pyramid 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 is sleeved in the energy consumption section, feature
It is：Energy consumption section is made of at least one pyramid energy consumption unit along the axis direction of support；The 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
Each face of body, space body is made of r pyramid subelement, and wherein r is the odd number more than or equal to 3；The regular polygon
Number of edges m be integer more than or equal to 4；The pyramid subelement is by isosceles triangle board group four identical pieces of at four
A isosceles triangle 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 one
In a plane；The vertex of all pyramid subelements in the pyramid energy consumption unit on each face is in isoceles triangle
The outside and inside in the face that shape board bottom side is formed are alternately arranged.
The connecting plate that the end restraint section is reserved by components such as regular polygon steel plate, the short girder steel of T-type and beam columns forms,
Regular polygon steel plate is welded on energy consumption section end, and two short girder steels of T-type are welded to connect with regular polygon steel plate, 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.
Advantageous effect：
The present invention it is a kind of have staggeredly pyramid 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 for the unit that consumes energy with staggeredly pyramid, 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 pyramid consumes energy unit by pre-set folding line, and folding line is the intersection of two neighboring triangular plate
Line makes to be supported under geological process, at pre-set folding line, larger strain can occur to form yield line, reach
To the purpose of dissipation seismic energy.The present invention can only need to use the pre- of the components such as bolt and beam column to scene in factory process
Embedded part connects, and not only ensure that component quality, but also reduces the wet construction workload at scene, energy conservation and environmental protection.With staggeredly pyramid
The casing constraining anti-buckling support of type energy consumption unit had both had the flexible arrangement of the anti-buckling support of general restriction, can more effectively consume
The advantages that dissipating seismic energy, and the problems such as the component being connected with buckling restrained brace or larger joints can be solved, tool
There is good Popularizing of A.
