The main construction process: measuring the release line → installation of steel plate template around the floor → short beam welding on the steel beam → steel banding → reserved hole template installation → floor concrete pouring
General: The project is steel slab slab concrete, about ( ) m3, the concrete is self-mechanically stirred by the concrete mixing station of our unit, the self-unloading concrete transport truck is to the west side of the construction site, and then the concrete pump is transported vertically to the fourth. Floor level.
1. Structural concrete strength grade
According to the design requirements, the concrete strength grade of the slab is C30.
2. concrete transportation
The self-unloading concrete transport vehicle is used to the west side of the construction site, and then the concrete pump truck is used for vertical transportation to the four-storey floor.
3. mechanical equipment4. floor raft construction
Fully prepare the pouring materials and tools used for construction, and inspect and test all the tools, and prepare emergency plans to ensure that people, materials and materials can meet the requirements of pouring speed, ensure the supply of water and electricity, and prevent accidents.
A quality accident has occurred.
The material supply unit is required to provide the quality certificate, test report and actual samples of cement, sand, stone and admixture in advance, and provide a matching report.
The folded galvanized tile formwork and its support are inspected to ensure correct dimensions, strength, stiffness, stability and tightness to meet the requirements.
