Precise leveling device and construction method for cast-in-place once-formed concrete floor

Abstract

The invention provides an accurate leveling device for cast-in-situ concrete flooring formed in one step and a construction method. The device comprises a structural slab form and the reinforcement frameworks of beams, wherein a plurality of leveling adjusting racks are uniformly distributed and welded on the longitudinal reinforcement of each beam; each leveling adjusting rack comprises a semicircular bracket, a screw rod, an adjusting screw nut and a steel pipe sleeve; and steel pipe guide rails are longitudinally supported on the leveling adjusting racks. All mesh reinforcements, the leveling adjusting racks and the steel pipe guide rails supported on the leveling adjusting racks together constitute the accurate leveling device for the cast-in-situ concrete flooring formed in one step. The heights of the steel pipe guide rails are adjusted by rotating the adjusting screw nuts, and an automatic leveling rotating laser level gauge is adopted to determine that the heights of the steel pipe guide rails are correct. The accurate leveling device has the advantages that the structure is simple, part of elements can be used repeatedly in a turnover manner, the cost is low, the operation is simple and convenient, and the construction efficiency is high. Through the method provided by the invention, ground level control and accurate concrete construction leveling can be conducted for cast-in-situ concrete of each layer of floor; and the method is used for leveling operation for cast-in-situ concrete of each layer of floor and improves the flatness standard of the flooring.

Description

technical field [0001] The invention relates to a tool for leveling the ground of a building floor when concrete is poured, in particular to an accurate leveling device and a construction method for the floor of a cast-in-place once-formed concrete floor. Background technique [0002] With the rapid development of economic construction, in the construction projects of large shopping malls, garages, industrial plants and other housing projects, the application of cast-in-place once-formed concrete floors is increasing. In the construction of the cast-in-place concrete floor, the control of the flatness of each floor is the focus and difficulty of this type of project construction. With the construction of this type of project, various construction methods for controlling the flatness of the floor surface have appeared, but these construction methods generally have relatively complicated processes, low efficiency, and high cost.
