Construction method for improving concrete compactness of pitched roof
The invention discloses a construction method for improving concrete compactness of a pitched roof, which comprises the following steps of: building a support system and a template, binding a bottom-layer reinforcing mesh, mounting a truss rib flow choking device, binding an upper-layer reinforcing mesh, mounting a reinforcing steel bar guide rail, pouring concrete and the like. Concrete is integrally poured on the inclined plate face from low to high, the plate face concrete is formed in a two-layer pouring mode, the truss rib flow choking devices are arranged to effectively prevent the concrete from sliding down, the concrete compactness is improved, and the rigidity of the floor slab can be obviously improved by combining the truss rib flow choking devices with the upper reinforcing mesh and the lower reinforcing mesh. Two-layer step type pouring forming is adopted in concrete pouring, by means of the flow blocking effect of the truss rib flow blocking device, second-layer pouring can be conducted again after initial setting is completed in first-layer pouring, the concrete compactness can be effectively improved, and common quality problems such as pitted surfaces and leakage of the slope roof panel are prevented.
本发明公开了一种提高坡屋面混凝土密实度的施工方法，通过建立支撑体系及模板、绑扎底层钢筋网片、安装桁架筋阻流装置、绑扎上层钢筋网片、安装钢筋导轨、混凝土浇筑等多个步骤实施施工，混凝土在斜板面上整体按由低到高的顺序浇筑，板面混凝土分两层浇筑成型，通过设置桁架筋阻流装置可以有效防止混凝土下滑，提高混凝土密实度，通过桁架筋阻流装置结合上下钢筋网能够明显提高楼板刚度，混凝土浇筑采用两层阶梯式浇筑成型，利用桁架筋阻流装置的阻流作用，可以在第一层浇筑完成初凝后再次进行第二层浇筑，可以有效提高混凝土密实度，防止坡屋面板出现麻面、渗漏等质量通病。
