Compared with the prior art, the light assembly type buckling restrained brace disclosed by the invention has the advantages of being made of full steel, light in weight, easy to assemble, large in brace deformability, large in post-yield stiffness, low in residual deformation, wide in application range and the like.
Description
Technical field
The present invention relates to the seismic design field of the structure that builds a bridge, especially relate to a kind of lightweight assembling plate with opening core buckling restrained brace.
Background technology
The core cross section of existing buckling restrained brace is mostly alongst identical, destroy and often occur in the commissure of end stiffener rib or the non-slipping block end of centre, cause support maximum deformation quantity less (mean strain is lower than 3%), or need price high but the good Low Yield Point Steel of ductility to improve the ductility of support.Along with taking place frequently of global super large earthquake in recent years, the antidetonation of structure is also more and more higher to the requirement supporting maximum deformation quantity and its extremely low cycle fatigue performance, how to ensure that support still can normally work after can standing the attack of repeatedly violent earthquake, to ensure it without the need to changing in the total life cycle of work, relevant design concept also more and more comes into one's own.
Summary of the invention
Object of the present invention be exactly provide to overcome defect that above-mentioned prior art exists that a kind of all-steel, quality are light, easily assembling, supporting deformation ability is large, post-yield stiffness is large, low permanent set, lightweight assembling plate with opening core buckling restrained brace.
Object of the present invention can be achieved through the following technical solutions:
A kind of lightweight assembling plate with opening core buckling restrained brace, comprise core, fill plate peace treaty bundle plate, described filling plate is arranged on the left and right sides of core, described constraint plate is arranged on the both sides up and down of core, and be fixedly connected with filling plate by high-strength bolt, the middle part of described core is provided with non-slipping block, is provided with non-slipping block close-fitting groove in the middle part of described filling plate, described core is also provided with and organizes perforate more.
Described core comprises surrender section and is arranged on the non-compliant section at surrender section two ends, and described many groups perforate is arranged in surrender section, and described non-compliant section is provided with core end stiffener rib.
Described filling plate is provided with multiple bolt hole side by side, is fixedly connected with constraint plate by high-strength bolt.
Often organize perforate and all comprise multiple perforate be arranged side by side, and the shape of perforate is consistent, interval is equal.
The shape of described perforate comprises ellipse, rhombus and circle.
The 0.2-1 being spaced apart hole length between described multiple perforates doubly.
Gap is provided with between the two ends of described filling plate and non-compliant section.
Described core, filling plate peace treaty bundle plate are steel beam column.
Also be provided with without adhesives between described core and constraint plate.
Compared with prior art, the present invention has the following advantages:
One, all-steel, quality are light: the present invention replaces original filling mortar by the filling plate of steel, significantly reduces quality.
Two, easily assemble: filling plate of the present invention is assembled by bolt, easy to assembly by the two pieces of spill daughter boards attaching together formula, be easy to dismounting.
Three, largest variable is supported large: the present invention adopts the form of non-slipping block and groove fit guarantee core and fill relative motion less between mortar, and adopt the core of middle part open-celled structure, under the effect of earthquake large deformation, core tapping generation shearing deformation replaces the axial deformation supported, and increases support maximum distortion ability of the present invention.
Four, flexing bearing capacity is even: the perforate size of core of the present invention is identical with the distance between hole, makes core in perforate section uniform force, better can absorb energy, strengthens shock resistance.
Five, applied range: the number of openings of core of the present invention and position size all can change with different antidetonation demands, can adapt to different anti-seismic occasion, applied range.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
Embodiment:
The technical issues that need to address of the present invention are: the deficiency overcoming background technology, and propose a kind of lightweight all-steel buckling restrained brace with high deformation performance and high fatigue life, its core is the steel plate of perforate.The concrete technical scheme of buckling restrained brace is: assembly comprises core, non-cohesive material, constraint plate, fills plate and high-strength bolt, and primary clustering is made up of steel, thus greatly reduces the deadweight of support.Wherein, core tapping is due to weakened, and under large deformation, necking deformation finally can occur in the plane of weakness of tapping, and can not as buckling restrained brace.Make to retrain plate by the non-slipping block of centre, filling plate guarantees relative rigid motion less between each assembly with the interaction of the projection of core, thus reach the effect improving component deformability under the hysteresis such as earthquake load.In addition, under large deformation, the distortion of the axis supported can be converted into the shear strain of each perforate section, thus be equivalent to a metal damper be in series by multiple shearing damp device, thus stable and excellent circulation energy dissipation capacity can be obtained, for the anti-seismic performance of structure under violent earthquake provides more outstanding solution.
As Figure 1-3, the non-slipping block in the present invention in the middle part of core and corresponding draw-in groove of filling mortar are for the rigid motion limiting core, fill plate and retrain between plate.In order to reach larger deformability, the consistent size of each perform hole, and after ensureing perforate, the width of divided each little short column is the same, to reach identical cripling bearing capacity.Assembling process is as follows: be first attached on core by non-cohesive material, then assembles core, constraint plate and fills plate, final erection bolt.
