Embodiment

[0012] Embodiment: An example of concrete construction of a two-story structure on a certain floor in Xinzhan Development Zone, Hefei City.

[0013] The paving area of ​​this project is 43248M 2 , large area, roof column spacing 17000*12000mm, steel beam width 6000mm.

[0014] (1) Install the steel bar truss support formwork on the steel beam; take the roof column 4 as the benchmark, and control the elevation based on the thickness of the structural concrete that needs to be laid 150mm, and follow the direction of the truss mold on the steel beam, every Set a vertical short angle steel 2 on a straight line of 2000mm and bring an elevation control steel wire, the vertical short angle steel 2 is welded on the steel beam 3, and then set the direction along the straight line of the vertical short angle steel 2, 25*25*3 angle steel guide rail 1 and vertical short angle steel 2 are installed by spot welding, one side of angle steel guide rail 1 is placed vertically upwards and wel...

Abstract

The invention belongs to the technical field of building construction, in particular relating to a method for controlling concrete planeness of a large-area steel bar truss template. The method for controlling concrete planeness of the large-area steel bar truss template comprises the following steps of: firstly, arranging a horizontal angle steel guide rail, i.e. carrying out spot welding installation on the horizontal angle steel guide rail and a vertical short angle steel; then arranging the angle steel guide rail according to width of a steel beam; and then pouring structural concrete, compactly vibrating, and flat-pressing and compacting the vibrated concrete by using a roller along an angle steel track in a reciprocating way. In the method for controlling concrete planeness of the large-area steel bar truss template, the truss template and a concrete cast-in-place plate are combined as a structural layer and the planeness is arranged in a pouring region to control the angle steel guide rail, therefore, the planeness of a cast-in-place plate of the large-area steel bar truss template is effectively ensured about 2mm to 2m and the qualified rate is more than 90 percent when the large-area concrete is poured, and the laying precision of floor concrete of a large factory is enhanced.

Description

technical field [0001] The invention relates to a method for controlling the flatness of large-area reinforced truss mold concrete, which belongs to the technical field of building construction. Background technique [0002] At present, the large-area concrete construction method is mostly used as the sub-compartment construction method, that is, the concrete is divided into grids with a width of no more than 6000mm, the concrete is supported on both sides, the concrete is poured in the sub-compartment and the quality control of the concrete surface flatness is carried out. . For example, using the method of laying steel bar heads or welding steel bar heads on the ground base, and using the top elevation of the steel bar heads to control the elevation of the concrete top surface, this method is based on points and surfaces, and the construction operation is simple. / 2m, but it has high requirements for workers' operation skills, and the flatness control has many artificial ...
