Cold-formed steel composite shear wall and method for toughening wallboard of cold-formed steel composite shear wall at connecting piece
The invention discloses a cold-formed steel composite shear wall and a method for toughening a wallboard of the cold-formed steel composite shear wall at a connecting piece. The composite shear wall comprises a cold-formed steel structure frame and the wallboard fixed on the outer side of the cold-formed steel structure frame through a self-tapping screw, and the wallboard is attached with pastingpieces made of a fiber material through an interface structural adhesive at the connecting position of the self-tapping screw to serve as a toughening structure; and the pasting density of the end part, the corner part and the hole of the wallboard is increased. The pasting pieces have the advantages of being high in strength, high in elastic modulus, high in tenacity and easy to machine, the tenacity of the portion, at the self-tapping screw connecting position, of the wallboard is greatly enhanced through bonding of the interface structural adhesive and the wallboard, and especially the pasting pieces are densely arranged at the large-stress end, corner and hole of the wallboard, so that the toughening effect of the areas is better. The wallboard made of a brittle material can absorb more energy under the action of earthquake and wind load through toughening treatment at the joint of the self-tapping screw, so that the wallboard is prevented from cracking at the joint of the self-tapping screw; and meanwhile, the toughening treatment weakens the force transmission effect of the self-tapping screw on the wallboard.
本发明公开了一种冷成型钢复合剪力墙及其墙板在连接件处的增韧方法，复合剪力墙包括冷成型钢结构架和通过自攻螺钉固定于其外侧的墙板，墙板在自攻螺钉连接处通过界面结构胶贴附纤维材料的贴覆片作为增韧结构；墙板端部、角部及墙板上洞口处贴覆片的贴附密度加大。贴覆片具有高强度、高弹模、高韧性和易于加工的优势，通过界面结构胶与墙板粘结，使墙板在自攻螺钉连接处的韧性大大增强，尤其在墙板受力较大的端部、角部及洞口处密集的设置贴覆片，使这些区域的增韧效果更好。脆性材料的墙板在自攻螺钉连接处的增韧处理，可在地震及风荷载作用时吸收更多的能量，从而阻止墙板在自攻螺钉连接处的开裂。同时增韧处理使自攻螺钉对墙板的传力作用减弱。
