4. improve structure anti-side rigidity, reduce supporting member sectional dimension, increase structure ductility.
Buckling restrained brace is that the one be made up of anti-buckling support inner core and confining part relies on core tension and compression surrender power consumption, and constraint mechanism provides the structure lateral resistant member of anti-side rigidity.Tension and compression load surrender power consumption mainly born by core, and the effect of confining part prevents inner core from when pressurized, complete buckling occurring and retraining its cripling, makes inner core can reach the abundant surrender of total cross-section under pulling force and pressure effect.Therefore, in the design and fabrication process of buckling restrained brace, require that its power transmission is clear and definite, be easy to make and construction, cost-saving.And traditional buckling restrained brace adopts Steel concrete to be combined to form restraining tube usually, the making required precision of this class A of geometric unitA is high, from great and difficulty of construction is large, and larger imposed load is existed to core cell itself, preparation method is loaded down with trivial details, cause its promote and the scope of application limited, industrialized level is lower.
Summary of the invention
For prior art Problems existing, the invention provides one and can transmit axial push-pull load preferably, give full play to the performance of the dissipation seismic energy of support, meet the requirement of bearing capacity and dissipation seismic energy, again can saving steel cost and fabrication cycle, be easy to construct and " one " font all steel type buckling restrained brace of industrialization production.
To achieve these goals, the present invention adopts following technical scheme, and a kind of " one " font all steel type buckling restrained brace, comprises rectangular steel tube, be provided with " one " font core in the inside of rectangular steel tube, the two ends of described " one " font core are stretched out rectangular steel tube and are arranged on outside rectangular steel tube; Be coated with non-cohesive material layer outside " one " font core in rectangular steel tube, between " one " font core and the inwall of rectangular steel tube, be provided with two angle steel groups, described angle steel group is symmetricly set on the both sides of " one " font core; Be fixed with triangular steel plate stiffening rib in the inner side of angle steel, " one " font core outside rectangular steel tube is provided with frictional high-strength bolts hole, " one " font core and leave gap between angle steel and triangular steel plate stiffening rib.
Described angle steel is fixed in rectangular steel tube by bolt symmetry.
Described angle steel and triangular steel plate stiffening rib adopt fillet weld to be connected.
Described angle steel group and bolt interlaced arrangement.
Described bolt is that four arrangements are put, and often five roads are put in arrangement.
Beneficial effect of the present invention:
1, " one " font all steel type buckling restrained brace of the present invention, angle steel, triangular steel plate stiffening rib, rectangular steel tube and bolt composition constraint mechanism, the non-cohesive materials such as the epoxy resin of core cell and peripheral spraying thereof are placed in inside, buckling restrained brace can be prefabricated in the factory, use crane lifting BRB at the construction field (site), complete buckling restrained brace by frictional high-strength bolts with nut scene and be connected with the gusset plate of node; The installation of buckling restrained brace of the present invention can be not counted in total time of construction, facilitates structure Construction treatment, does not affect main structure body construction; And be easy to realize suitability for industrialized production, site assembly is easy, building site accurate positioning, thus greatly saves the set-up time, improves engineering efficiency, is worth Devoting Major Efforts To Developing and popularization, is widely used in Practical Project.
2, " one " font all steel type buckling restrained brace of the present invention is all steel type, the restraining tube mechanism of angle steel, triangular steel plate stiffening rib, bolt and rectangular steel tube composition provides larger second moment of area for buckling restrained brace, and then provides enough lateral rigidities; Therefore, the strength and stiffness of buckling restrained brace are obtained for lifting, meet the design principles of surrender power consumption.
3, the present invention compares with the concrete buckling restrained brace of " one " font, and buckling restrained brace of the present invention has easy construction, simple structure, alleviate and support with the deadweight of structure, give full play to the advantages such as steel strength; Compare with other all steel type buckling restrained braces, buckling restrained brace of the present invention has simple structure, and construction makes the advantages such as fast, energy dissipation capacity is excellent.
