Description

Combined steel pipe-encased concrete type buckling-restrained brace member
Technical field
The present invention relates to a kind of curvature-prevention support component, be specifically related to a kind of lateral resistant member (also being a kind of energy-consumption shock-absorption device) that is mainly used in the structural engineering field.
Background technology
Existingly have the following disadvantages: (referring to Fig. 4 and Fig. 5) with the curvature-prevention support component of cast-in-place concrete filled steel tube as lateral restraint, at first, in order to allow the in-line brace inner core can be at concrete filled steel tube internal freedom tension and compression dilatation, need to paste soft material plate 3 to reserve the axial compression space in the put more energy into end of floor 2 of in-line brace inner core 1, in order to isolate the adhesion stress between in-line brace inner core surface and the concrete, also need supporting core surface brushing non-cohesive material plate 4 simultaneously; Then, insert in-line brace inner core 1 in the outside steel pipe 5 and be positioned position in the middle of it; At last, filling all the other spaces between steel pipe 5 and the in-line brace inner core 1 also with mortar or concrete cast-in-situ, vibration compacting becomes one in-line brace inner core 1, steel pipe 5 and concrete.This traditional fabrication mode can cause following problem: one, the manufacturing deficiency of in-line brace inner core: the in-line brace inner core great majority during the anti-flexing of tradition supports adopt making flow process as shown in Figure 1-Figure 3.Generally, need the end cross-sectional of in-line brace inner core 1 be amplified, and traditional method is to adopt the NC Flame Cutting technology to be cut into in-line brace inner core along supporting the plate length direction in order to guarantee factors such as supporting base end portion elasticity and consideration connection 1Shape, this processing mode generally needs higher cost of production, and can cause the excess waste of sheet material, the back of flame cutting simultaneously can retain residual tension at flame cutting plate edge, can the low cycle fatigue property of in-line brace inner core 1 be had a negative impact if deal with improperly.Two, the end product quality problem of supporting member: mortar or the concrete cast-in-place and work progress that vibrates cause the local damage of 3 displacements of special soft material plate and non-cohesive material plate 4 easily, therefore the construction production technique is proposed higher requirement, be not easy to actual production.In addition, back inner core and concrete filled steel tube become one because cast finishes, therefore the engineering staff is difficult to check whether inner soft material plate 3 and non-cohesive material plate 4 take place to be shifted or to damage, even check and come out also to be difficult to make corresponding means to save the situation, therefore be difficult to guarantee the quality of finished product.Three, the production cycle defective of supporting member: generally after pouring mortar or concrete, at least about 7 days time such as need carries out maintenance to concrete and condenses and strength enhancing to treat it, can lift engineering site then and install, and concrete maintenance processes can obviously prolong the production cycle of supporting member and drag slow programming.
Summary of the invention
The present invention is in order to solve in-line brace inner core processing cost height in the existing curvature-prevention support component, can't to guarantee that it has reliable low cycle fatigue property, mortar or the concrete cast-in-place and work progress that vibrates causes the local damage and the long problem of production cycle of special soft material plate displacement and non-cohesive material plate easily, and then a kind of combined steel pipe-encased concrete type buckling-restrained brace member is provided.
