组合模板钢框申请号 89216850.1 公告号 CN2068540U 这种组合模板钢框主要由端肋、边肋、中肋、斜撑和横撑等杆件组成。端肋和边肋焊成矩形框架。边肋采用了3mm厚薄钢板制成,每隔规定的间距向内冲折出一个与肋体内侧面成90°的支撑板。中肋为上、下翼缘宽度不相等的冷冲压成型薄壁型钢,其两端分别焊接在端肋的内侧。中肋的数量根据设计计算确定。中肋与中肋之间以及边肋与中肋之间设置斜撑,斜撑亦为冷冲压成型薄壁型钢。横肋为2mm厚薄钢板,设于边肋与中肋之间,最上一根与最下一根为贯通的横肋。横肋的功能在于增强钢框刚度和防止局部变形。
Combined formwork steel frame No. 89216850.1 Announcement No. CN2068540U This combination formwork steel frame is mainly composed of end ribs, side ribs, middle ribs, diagonal braces and cross braces and other bars. The end ribs and side ribs are welded into a rectangular frame. The side ribs are made of 3 mm thick steel sheet and are punched inward at regular intervals to form a support plate that is 90° to the inner side of the ribs. The middle ribs are cold stamping formed thin-walled steels with unequal widths of the upper and lower flanges, and the two ends thereof are respectively welded to the inside of the end ribs. The number of middle ribs is determined based on design calculations. Between the middle ribs and the middle ribs and between the side ribs and the middle ribs, diagonal braces are provided, and the diagonal braces are also cold stamping formed thin wall sections. The transverse ribs are 2mm thick steel plates, which are located between the side ribs and the middle ribs. The top and bottom ones are transverse ribs. The function of the transverse ribs is to enhance the rigidity of the steel frame and prevent local deformation.
