Comprehensive floor rebar protective layer and structure elevation control method

Abstract

The invention belongs to the technical field of building structure engineering construction and provides a comprehensive floor rebar protective layer and structure elevation control method. The comprehensive floor rebar protective layer and structure elevation control method aims at solving the problem that comprehensive accurate control over the elevation of floors and the thickness of rebar protective layers is difficult in an existing cast-in-place structure floor concrete construction process. According to the core technology, multifunctional rebar split heads are adopted, and according to the core process, the rebar protective layers are adjusted accurately and the floor concrete elevation is controlled through all the functional parts of the rebar split heads. By the adoption of the multifunctional rebar split head control process, construction materials of concrete cushion blocks, common split heads and the like and construction methods of pull wire elevation control and the like can be completely replaced, a row of distribution rebars can be replaced directly, materials are saved, and the comprehensive floor rebar protective layer and structure elevation control method has the high social benefits and economic benefits.

Description

technical field [0001] The invention belongs to the technical field of building structure engineering construction, and in particular relates to a comprehensive control method for floor reinforcement protective layers and structural elevations of cast-in-situ structural floor slab elevations and protective layer thicknesses that are used for precise control. Background technique [0002] At present, the 50 control line marked on the column reinforcement is generally used in the construction of the floor slab concrete of the building cast-in-place structure. The stressed steel bar is mainly controlled by the support of the steel bar stool. [0003] In the actual construction process, when using the construction method of marking the 50-line stay rope to control the elevation and thickness of the slab, the process is cumbersome and the accuracy is poor, and the wire rope is not convenient for construction, and it is easy to be damaged during construction, which affects the con...
