Building protection frame stair tread
The invention discloses a building protection frame stair tread and a using method, a horizontal rear sliding groove is fixed to the rear portion of the tread, a horizontal front sliding groove is fixed to the front portion of the tread, the rear sliding groove is rotationally connected with a horizontal two-way lead screw, and the screwing directions of external threads of the left portion and the right portion of the two-way lead screw are opposite; the left portion and the right portion are in threaded connection with horizontal rear sliding blocks respectively, the two rear sliding blocks are in left-right sliding connection and rotating connection with the rear sliding grooves respectively, and rear supporting rods are fixed to the bottom ends of the two rear sliding blocks respectively. A steel pipe commonly used in a steel pipe frame is used for supporting, then the rear supporting cylinder can push the semi-locking plate to tightly hold the outer wall of the steel pipe through threaded connection of the main locking pipe and the rear supporting cylinder, and therefore the positions, relative to the steel pipe, of the main locking pipe and the rear supporting cylinder can be limited; and the rear sliding block is limited by the two-way lead screw, so that the rear supporting barrel can be prevented from moving along the steel pipe which is arranged at the included angle, and the position of the rear supporting barrel relative to the steel pipe can be limited.
本发明公开了一种建筑防护架楼梯踏板及使用方法，所述踏板后部固定有水平的后滑槽，且前部固定有水平的前滑槽，所述后滑槽转动连接有水平的双向丝杆，所述双向丝杆左右两部的外螺纹旋向相反，且左右两部各螺纹连接有水平的后滑块，两所述后滑块分别与后滑槽相左右滑动连接和转动连接，两所述后滑块底端分别固定有后支撑杆。本发明使用钢管架中常用的钢管进行支撑，然后通过主锁紧管与后支撑筒的螺纹连接能够使得后支撑筒推动半锁紧板抱紧在钢管外壁，从而能够对主锁紧管和后支撑筒相对钢管的位置进行限定，而通过双向丝杆对后滑块的限制能够避免后支撑筒沿着呈夹角设置的钢管进行移动，从而也能够对后支撑筒相对钢管的位置进行限定。
