Midpoint bolt reinforcement type laminated wood buckling restrained brace
The invention relates to a midpoint bolt reinforcement type laminated wood buckling restrained brace. The brace comprises a core energy dissipation steel plate (2) and two pieces of laminated wood (1), wherein clamping grooves matched with the core energy dissipation steel plate (2) are formed in the laminated wood (1), the core energy dissipation steel plate (2) is clamped by the two pieces of laminated wood (1) through the clamping grooves, and self-tapping screws (4) are connected between the two pieces of laminated wood (1); the restrained brace further comprises a long bolt (3); and the core energy dissipation steel plate (2) comprises a middle plate (21), wherein the middle plate (21) is symmetrically connected with two end plates (24) through connecting plates, a second through hole (211) is formed in the middle plate (21), first through holes (13) are formed in the laminated wood (1), and the long bolt (3) penetrates through the second through hole (211) and the first through holes (13) of the two laminated wood (1) and is fixed through a nut. Compared with the prior art, the brace has the advantages of high lateral rigidity, high buckling resistance, high ductility, low damage and the like.
本发明涉及一种中点螺栓加强型胶合木屈曲约束支撑，包括核心耗能钢板(2)和两块胶合木(1)，胶合木(1)上开有与核心耗能钢板(2)匹配的卡槽，两块胶合木(1)通过卡槽夹住核心耗能钢板(2)，两块胶合木(1)之间连接有自攻螺钉(4)，约束支撑还包括长螺栓(3)，核心耗能钢板(2)包括中间板(21)，中间板(21)通过连接板对称连接有两块端板(24)，中间板(21)上设有第二通孔(211)，胶合木(1)上设有第一通孔(13)，长螺栓(3)穿过第二通孔(211)以及两块胶合木(1)的第一通孔(13)，并通过螺母固定。与现有技术相比，本发明具有侧向刚度大、抗屈曲能力强、高延性和低损伤等优点。
