Split bolt anti-loosening device of large-size concrete wall formwork supporting system
The invention discloses a large-size concrete wall formwork supporting system split bolt anti-loosening device which comprises a split bolt, a screw rod, a supporting piece, a fixing piece and a fastening piece, the supporting piece is arranged on the outer side of the screw rod, the fixing piece is arranged on the outer side of the screw rod, the fastening piece is arranged on the outer side of the fixing piece, and a limiting assembly is arranged on the outer side of the fixing piece. The limiting assembly is arranged on the outer side of the fixing piece, and the fixing sleeve is arranged on the outer side of the fixing piece. A screw rod is rotated by a fixing head to drive a pressing block to move in a fixing sleeve, the pressing block makes contact with a connecting rod to press the connecting rod downwards, a bent rod is expanded outwards according to the lever principle, the bent rod is clamped in a clamping groove in a second nut, teeth on the bent rod can improve the friction force of the outer side of the bent rod, the firmness of the bent rod in the clamping groove is improved, and the service life of the bent rod is prolonged. Therefore, the first nut is fixed in the second nut, and the nut is prevented from falling off.
本发明公开了一种大尺寸混凝土墙体模板支撑体系对拉螺栓防松动装置，包括对拉螺栓、螺杆、支撑件、固定件和紧固件，所述支撑件设置于所述螺杆的外侧，所述固定件设置于所述螺杆的外侧，紧固件设置于所述固定件的外侧，以及限位组件，限位组件设置于所述固定件的外侧，固定套设置于所述固定件的外侧。本发明利用固定头转动丝杆带动压块在固定套内部移动，压块与连接杆接触使其向下压，通过杠杆原理使弯杆向外扩，将弯杆卡接在第二螺帽上卡槽的内部，弯杆上的齿牙可以提高弯杆外侧的摩擦力，提高弯杆在卡槽内部的牢固度，从而将第一螺帽固定在第二螺帽的内部，防止螺帽脱落。
