Novel back shore used for attached lifting scaffold
The invention discloses a novel back shore used for an attached lifting scaffold. The novel back shore comprises a screw rod, a support jacking block and a connecting block, wherein the screw rod includes a first threaded part located at one end of the screw rod and a second threaded part located at the other end of the screw rod, and the first threaded part and the second threaded part have opposite rotating directions; the support jacking block and the connecting block are both installed on the screw rod, and the support jacking block is in threaded connection with the first threaded part; asnap groove extending in the radial direction of the screw rod and provided with two ends through is formed in the end part of the end, away from the second threaded part, of the support jacking block; the connecting block is in threaded connection with the second threaded part; and the side wall of the end, away from a first connecting part, of the connecting block is provided with an axle holewith the same extending direction as the snap groove and with two ends through. According to the novel back shore, by adjusting the length and angle of the back shore installed on a wall-attached support, so that the snap groove on the support jacking block can prop up a cross bar on a scaffold body, thereby achieving a good anti-fall support function; and the back shore is simple in structure andconvenient to process.
本发明公开了一种附着式升降脚手架用新型支顶器顶撑，包括：丝杆、支撑顶块和连接块，其中：丝杆包括位于其一端的第一螺纹部和位于其另一端的第二螺纹部，且第一螺纹部与第二螺纹部的旋向相反；支撑顶块和连接块均安装在丝杆上，且支撑顶块与第一螺纹部螺纹连接，支撑顶块远离第二螺纹部一端的端部开设有沿丝杆径向方向延伸且两端贯通的卡槽，连接块与第二螺纹部螺纹连接，连接块远离第一连接部一端的侧壁设有与卡槽延伸方向一致且两端贯通的轴孔。本发明通过调节安装在附墙支座上的支顶器顶撑的长度和角度，使得支撑顶块上的卡槽可以顶住架体上的横杆，从而可以起到良好的防坠支撑作用。且支顶器顶撑结构简单，加工方便。
