Abstract: A safe scaffold includes door type frames, crossbars, and toe boards. The door type frame has a ledger, located in the lower end, connected to standards that are parallel to each other and are installed with combined pins thereon individually. The crossbar includes joint bar members having engaging holes engaged with the combined pins of the door type frame, and connects one door type frame to another door type frame in a cross link method, or connected to other joint bar members through the engaging couplers. The toe board is provided on the ledgers of every two adjacent door type frames. The invention creates an available space for setting guardrails by lowering the position of the toe board of the scaffold, adjusts the position and combination of the crossbars to form guardrails, and reduces the gaps of side rails.

Abstract translation: 安全的脚手架包括门型框架，横梁和脚趾板。 门型框架具有位于下端的分类帐，其连接到彼此平行的标准，并且单独地安装有组合销。 横杆包括具有与门型框架的组合销接合的接合孔的接合杆构件，并且以交叉连接方式将一个门型框架连接到另一门型框架，或者通过接合联接器连接到其他接合杆构件。 脚趾板设置在每两个相邻门型框架的分类帐上。 本发明通过降低脚手架的脚趾板的位置，调整十字杆的位置和组合来形成护栏，从而形成了设置护栏的可用空间，并且减小了侧轨的间隙。
