The delivery list template of the plastic sheet manufacturer has the function of automatic sorting and self delivery quantity. It is a “Jincheng” system that balances the types of binders and does not separate and discharge materials.
Composite steel formwork can be combined with steel formwork to form a composite steel formwork or serve as a framework for the formwork. The inner and outer surfaces of the combined steel template can be made into any spherical surface. Commonly used are polyurethane rigid foam plastics and one kind of rigid foam plastics.
Reasonable combination of steel templates and effective protection of steel templates will result in longer service life and lower overall costs.
For standard concrete pouring sequences, composite steel formwork should be used as much as possible. The allowable time for the combined steel formwork requires a period of time. The importance of watering is that both water and electricity inside the mold need to be stored. If construction is strictly carried out according to the design plan, it is difficult to control the combination.
The correct combination of steel formwork processes is crucial. Strictly select according to the standards, usually after two or three sanding cycles. The selected cement is cement, usually 6% cement.
The pouring width of the bottom plate and side wall for concrete pouring should be controlled at around 250 millimeters to reduce the constraint of thickness on the composite steel formwork.
The pouring width of the bottom plate and side wall for concrete pouring should be controlled at around 250 millimeters, and the thickness of adjacent templates should be controlled at around 200 millimeters. After pouring, the surface should be cleaned and dried.
● Treatment of defects on the concrete surface before pouring: If defects are excavated along the structural joint, the corrugated steel tiles should be carefully cleaned, and PO adhesive or sanding cement should be applied to the crack area. PO adhesive should be applied to the old bottom plate and bottom plate.
Base surface cleaning → old slurry treatment of the bottom plate → base surface wetting → sanding cement slurry leveling layer → curing → protective layer curing.
Before pouring concrete, the base surface should be cleaned of impurities and firmly measured, and there should be no sand or hollowing.
If the base surface does not comply with the following regulations, it should be repaired and leveled with mortar at the defects (such as the bottom plate, wall root, etc.).
The construction of the waterproof layer should be carried out as soon as possible to fully ensure the quality of the waterproof construction organization and ensure the construction quality of the waterproof layer.
When the moisture content of the base layer is higher than 3%, the construction is carried out by brushing, and the coating operations are also carried out on both sides; When the moisture content of the base surface is higher than 6%, a waterproof layer should be laid and a waterproof roll construction plan should be formulated.
Strictly implement the word “waterproof”: “requirements for waterproofing” (requirements for waterproofing). During the “waterproof construction” work, the base layer should be treated first to remove any debris and to ensure that it is not firmly adhered to the waterproof membrane.
The waterproof layer should comply with the specified quality standards and meet the design requirements and specifications.
