Problems solved by technology
There are two problems in this fixing method: 1. After the steel bars or expansion bolts are nailed into the foundation of the floor, the moisture-proof layer in the foundation of the floor will be destroyed, which will affect the moisture-proof effect of the floor
2. The reinforced mesh set in the floor surface layer is supported by reinforced stirrups and controls the thickness of the reinforced protective layer. However, during the construction process, construction personnel often step on the reinforced mesh, which causes the reinforced mesh to collapse. After the concrete is poured, the protective layer is too large to cause the floor to crack and affect the concrete elevation
However, the use of wooden formwork is inconvenient for demoulding, and it is not convenient for later turnover and reuse, and the fixed structure of the formwork will still damage the moisture-proof layer, thereby affecting the moisture-proof effect of the floor
At the same time, the formwork structure cannot well support the steel mesh

The invention discloses a large-area concrete wear-resistant floor construction process, which comprises the following steps: cleaning the base; constructing the base; measuring the base and setting out lines on the base to divide a plurality of independent construction bins; prefabricating steel formwork and preparing formwork support material, the height of the steel formwork is less than the design elevation of the floor, and the formwork support material includes a support standpipe with a jack on the upper end and a fastening assembly matched with the support standpipe; the steel formwork and formwork are installed in the way of jumping Support; install steel mesh sheets at intervals in the width direction of each construction warehouse to support the tension bars, and then arrange steel mesh sheets on the steel mesh reinforcement bars. Concrete is the same as the grade of fine stone concrete to form a sealing layer; pour fine stone concrete; install steel mesh sheets to support the tension bars in the width direction of the remaining construction warehouses and then pour concrete. The large-area concrete wear-resistant floor obtained by the invention has high construction process efficiency, and the floor layer will not crack.
Description
technical field [0001] The invention relates to the field of floor construction, in particular to a large-area concrete wear-resistant floor construction process. Background technique [0002] In the process of large-area floor construction, it is often necessary to carry out segmented and sub-storage construction. During construction, wood formwork or steel formwork is usually used as the floor formwork. The reinforcement system of the wood formwork is generally back corrugated or short wooden squares. The reinforcement system of the steel formwork is generally reinforced by the surrounding structural columns or driven into the foundation of the floor. Steel bars or expansion bolts are used to fix the steel formwork on the floor foundation through steel bars or expansion bolts. There are two problems in this fixing method: 1. After the steel bars or expansion bolts are nailed into the foundation of the floor, the moisture-proof layer in the foundation of the floor will be ...
