定型组合钢模板不但适用于各种不同尺寸的现浇混凝土梁、板、墙、柱,也可以应用在楼梯工程上。长城饭店工地在楼梯施工中也使用了小钢模,取得了良好效果。支模的具体方法是首先根据工程图纸尺寸要求放出大样,找出各部角度,然后选用不同类型的定型组合模板进行拼装,楼梯休息平台、侧帮、底模均用小钢模,阴角处加角模,用U形卡连结牢固。楼梯踏步侧帮模板由工地自制,用2毫米厚铁板和8号槽钢点焊连结成型。每步两块侧帮,在制造和安装
The fixed combination steel formwork is applicable not only to cast-in-situ concrete beams, plates, walls, and columns of various sizes, but also to stair works. The Great Wall Hotel site also used a small steel mold in the construction of the stairs and achieved good results. The specific method of supporting the mold is to first release large samples according to the size requirements of the engineering drawings, find out the angles of the various parts, and then use different types of stereotyped composite templates for assembly. The stair rest platform, side and bottom molds all use small steel molds, and the female corners Add corner molds and connect them securely with U-shaped cards. Stair step side stencils are made by the site and are formed by spot welding using 2 mm thick iron plate and 8 channel steel. Two side gangs per step in manufacturing and installation
