Stand column of stairwell steel frame and stairwell steel frame
The invention discloses a stand column of a stairwell steel frame and the stairwell steel frame. The stand column of the stairwell steel frame comprises a stand column body and a plurality of reinforcers, and the stand column body is formed by bending a steel plate. The stand column body comprises two first bent parts, two second bent parts and two third bent parts, wherein the two first bent parts are folded from the middle of the steel plate in the length direction of the steel plate to form an included angle, the two second bent parts are correspondingly arranged at the outer ends of the two first bent parts and bent inwards, and the two third bent parts are correspondingly arranged at the outer ends of the two second bent parts and bent outwards. The multiple reinforcers are distributed between the two third bent parts; each reinforcer comprises two positioning parts and a first reinforcing part, wherein one ends of the two positioning parts are connected with each other and included angles between the two positioning parts are right angles, and the first reinforcing parts are arranged at the included angles between the two positioning parts in a matched mode; and the cross sections of the first reinforcing parts are in a right triangle shape. According to the stand column of the stairwell steel frame, the structure is simple, the assembly is convenient, the production costis low, and the rigidity of the reinforcers and stand column can be enhanced by arranging the first reinforcing parts.
本发明公开了一种梯井钢架的立柱及梯井钢架，其中，该梯井钢架的立柱包括有立柱主体和加强件，立柱主体由钢板折弯而成，立柱主体包括有沿着钢板的长度方向自钢板中部对折并形成一夹角的两个第一折弯部、分别设置在两个第一折弯部的外端的且向内折弯的两个第二折弯部及分别设置在两个第二折弯部的外端的且向外折弯的两个第三折弯部；加强件设有多个，多个加强件分布于两个第三折弯部之间；每个加强件均包括有一端相互连接的且夹角为直角的两个定位部及匹配设置在两个定位部之间的夹角处的第一加强部；第一加强部的横截面呈直角三角形状。本发明结构简单、组装方便且生产成本低，通过设置第一加强部能够增强加强件整体和立柱整体的刚度。
