What do precast concrete components belong to? What are the characteristics? Precast concrete components suppliers take you to understand

Precast concrete is a kind of precast products. It is a process of pre-processing the concrete parts of buildings or structures in factories or construction sites. Precast concrete components are used for assembly and construction. The main products are prestressed concrete slabs and beam components. Because of its light weight and low price, it can replace scarce wood. It is a commercial component with Chinese characteristics and broad development prospects, it has the advantages of saving labor, overcoming seasonal influence and facilitating construction in all seasons of the year.

Features of precast concrete components:

1. Good structural performance, factory production can effectively ensure the mechanical properties of the structure, and the dispersion is small.

2. The construction speed is fast, the product quality is good, and the surface finish is high, which can achieve the decorative effect of fair-faced concrete and make the structure and the building unified and coordinated.

3. Factory production saves energy, is conducive to environmental protection, and reduces on-site construction noise.

4. Good fireproof and fire resistance.

5. The overall performance of the structure is poor, not suitable for buildings with high seismic requirements.

There are many kinds of precast concrete components: columns, foundation beams, crane beams, roof beams, trusses, roof panels, eaves gutters, skylight frames, wall panels, flower basket beams, floor slabs of multi-storey factory buildings, etc., including foundation piles, floor slabs, lintel, balcony, stairs, internal and external wall panels, frame beams, columns, roof cornice panels, decorative parts, etc., for civil buildings.

What safety issues should be paid attention to in the installation and removal of precast components? The supplier of precast concrete components will take you to know

Suppliers of precast concrete components should not only pay attention to the problems of the project itself, but also pay attention to the safety of workers in the construction process. In order to ensure the safety of construction personnel, suppliers of precast concrete components remind everyone that the following safety measures should be taken during construction:

When working at high altitude, all kinds of accessories should be placed in toolboxes or tool bags, and it is strictly forbidden to put them on templates or scaffolding. In addition, it is forbidden for high-altitude operators to climb up and down on the combined templates or scaffolding, and they are not allowed to walk on the top of the wall and its templates at high altitude.

Wear a safety helmet before work, check whether the tools used are firm, wrenches and other tools are hung on the body with ropes and chains to prevent people from falling, and concentrate on thinking when working to avoid nails sticking feet and falling into the air.

Suppliers of precast concrete components remind that scaffolding and protective railings should be set up when installing and dismantling formwork exceeding 5m. It is forbidden to operate up and down in the same vertical plane. Safety belts should be fastened when working at high altitude. Attention should be paid not to pile up a large amount of formwork and other materials on the scaffolding. 36V low-voltage power supply should be used for wires and electric tools erected on the formwork, or other effective safety measures should be taken.

Factors affecting the durability of prefabricated components is steel corrosion, steel corrosion is mainly from the concrete protective layer carbonation and chloride ion erosion, both are carried out with water as the carrier, and water is also the concrete freeze-thaw cycle, aggregate reduction reaction and other damage phenomenon of one of the main reasons, visible bridge waterproof on the durability of the bridge is very important.
