Construction method and construction device for controlling flatness of cast-in-place reinforced concrete slope surface of discharging platform

Abstract

The invention particularly relates to a construction method and a construction device for controlling the flatness of a cast-in-place reinforced concrete slope surface of a discharging platform. The construction method comprises the following steps: 1) slope structural formwork erection; 2) setting of a downward scraping rod guide rails; 3) concrete pouring, vibrating and flattening; 4) scraping; 5) removal of scraping rod guide; 6) concrete grouting and polishing; 7) water conservation of concrete covered with membrane. The construction device comprises a slope structure frame and the device is characterized in that a plurality of scarping rod guide rails are distributed on the slope surface of the slope structure frame at intervals, each of the scarping rod guide rails extends from the top to the bottom of the slope; the bottom of each scraping rod guide rail is provided with a plurality of guide rails supports; the upper ends of the guide rail supports are connected with the bottoms of the scraping rod guide rails and the lower ends thereof are fixed on the support frame of the slope structure. The construction method and the construction device for controlling flatness of cast-in-place reinforced concrete slope surface of the discharging platform have the advantages of bringing convenience to construction and achieving good construction effect.

Description

technical field [0001] The invention belongs to the technical field of concrete construction, and in particular relates to a construction method and a device for controlling the flatness of a cast-in-place reinforced concrete slope slab on an unloading platform. Background technique [0002] In the construction process of waste incineration power plants, the unloading platform, as a functional component, is generally designed as a slope surface. As we all know, as a cast-in-place reinforced concrete structure slab construction, the elevation is generally measured by the 50mm line measured on the steel bar during the concrete pouring process, and the cross-stayed meter ruler is used to measure, and then the aluminum alloy rod is used to level the concrete to control the structural entity elevation. . However, for the slope surface of the unloading platform, if the conventional method of pulling 50 wires and aluminum alloy rods is still used for construction, the flatness con...
