During the production process of concrete precast components, attention should be paid to ensuring quality

Precast concrete components are well used in factory workshops and warehouses. They are relatively stable in all aspects, have good structural mechanical properties, clear force transmission levels, and simple geometric shapes. They are a kind of economical load-bearing components that can be made into large spans and large coverage areas. During production, certain scientific principles, such as physical mechanics, etc., must be paid attention to to make the products more practical. Here are the introductions:

1. Precamber. The setting of pre-camber is a calculated value and actual construction beam, which may be biased. It is a comfort index. In special industries, it may become a control value.

2. Detailed performance indicators. Workability of fresh concrete, setting time, mechanical properties of hardened concrete. Mainly refers to intensity.

3. The strength of the concrete roof panels meets the design requirements. The durability of concrete is a comprehensive one. Frost resistance and carbonization resistance are two important aspects of the durability of concrete, fly ash and other air entrainment.

Concrete roof panels are a type of reinforced concrete load-bearing member, consisting of a wide panel and two narrow and high ribs. Although the production process is entirely completed by machines, some issues should also be paid attention to during the production process to avoid substandard quality of the materials produced. This is not only irresponsible to consumers, but also has a certain impact on the reputation of your own company, so you must pay attention to ensuring quality during the production process.

Most of the domestic building structures today are designed as cast-in-place concrete structures. The more common structural forms include frame structures, shear wall structures, frame-shear structures, core tube structures, tube-in-tube structures, etc. Their common feature is that most of the components are cast-in-place, and only a few secondary components such as door and window lintels are prefabricated. , prefabricated concrete component technology has brought a brand-new topic, and it is proposed that the buildings in the above structural form, including exterior walls, stairs, kitchens and bathrooms, beams, slabs and even columns, use prefabricated components, which are assembled together during construction and the nodes are processed to form a complete building design and construction technology. This technology has the following characteristics:

1. The components are pre-made in the factory, which saves material loss caused by on-site pouring and environmental pollution to the construction site, and reduces construction waste emissions.

2. The on-site assembly of prefabricated components saves a lot of labor compared to the cast-in-place system and improves construction efficiency.

3. The exterior wall decoration surface and exterior windows can be completed after the prefabricated exterior wall is formed. The exterior wall decoration and exterior windows are already formed after on-site assembly. There is no need to set up exterior wall scaffolding during the construction period, which saves costs and reduces safety hazards.

4. Prefabricated components are used in construction through industrial production, which can effectively reduce the production cost of construction projects.

5. Prefabricated components are standardized and maintained in the factory. The quality is much more stable than on-site sites where there are many uncertain factors. It has a significant effect on improving the overall project quality and building quality.
