一般砖混结构住宅楼,每层或隔层设置钢筋混凝土圈梁,圈梁断面多为240毫米×180毫米或370毫米×180毫米。以往支圈梁模板用木横担支撑,周转次数少,费木材。近年来,我们采用组合卡具支模.这种做法支拆模方便,卡具可以多次周转使用,应用效果很好。组合卡具由于刚度较大,可作为“硬架支模”,也就是支模后安装空心楼板,再浇筑混凝土,一般3天后就可以拆模了,加快了工程进度。 General brick-concrete structure residential buildings, each floor or compartment with reinforced concrete ring beam, ring beam section is mostly 240 mm × 180 mm or 370 mm × 180 mm. In the past, support beam stencils were braced with wooden cross braces, and the number of turnovers was low, and wood was used up. In recent years, we have used modular fixtures to support molds. This is a convenient way to support and remove molds. Fixtures can be used several times in turn, and the application effect is very good. Since the combination fixture has a relatively large rigidity, it can be used as a “hard frame support mold,” that is, after the mold is installed, the hollow floor is installed and the concrete is poured. Generally, the mold can be removed after 3 days, which accelerates the progress of the project.
