3. economize in raw materials, while minimizing concrete, steel waste, improve original stress performance, also can reuse;
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.
Utility model content
For prior art Problems existing, the utility model provides one can transmit axial push-pull load preferably, give full play to the performance of the dissipation seismic energy of support, again can saving steel cost and fabrication cycle, be easy to construct and " ten " font four angle steel formula buckling restrained brace of industrialization production.
To achieve these goals, the utility model adopts following technical scheme, and a kind of " ten " font four angle steel formula buckling restrained brace, comprises " ten " font core, be coated with non-cohesive material layer in the outside of " ten " font core; Described " ten " font core is arranged on four angle steel inside, and the two ends of " ten " font core are stretched out angle steel and are arranged on angle steel outside, and " ten " font core of angle steel outside is provided with frictional high-strength bolts hole; Between the outer end of " ten " font core, two blocks of angle steel, arrange the rectangle bloom with through hole, rectangle bloom and angle steel, through the described through hole of rectangle bloom and the angle steel of both sides thereof, are fixedly connected into constraint mechanism by bolt; Leave gap between described " ten " font core and angle steel, be fixed with in the outside of angle steel floor of putting more energy into; The sectional dimension being positioned at the cross core of angle steel outside is greater than the sectional dimension of the cross core being positioned at angle steel inside.
Described bolt is that four arrangements are put, and often five roads are put in arrangement.
Floor of putting more energy into outside described bolt and angle steel is crisscross arranged.
The layout connected mode of the constraint mechanism that described bolt forms with angle steel and rectangle bloom.
The beneficial effects of the utility model:
1, " ten " font four angle steel formula buckling restrained brace of the present utility model, angle steel, rectangle bloom 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 utility model 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, " ten " font angle steel formula buckling restrained brace of the present utility model is all steel type, and angle steel, rectangle bloom and bolt composition constraint mechanism 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 utility model compares with the concrete buckling restrained brace of " ten " font, and buckling restrained brace of the present utility model 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 utility model has simple structure, construction makes the advantages such as fast, energy dissipation capacity is excellent.
