Prefabricated Beam Support for Factory Building Roofs

It is not recommended to directly paste and use prefabricated beam supports for factory building roofs. Instead, the cast-in-place method is recommended. When purchasing molds, choices should be made according to needs and professional teams should be consulted.

I. Risks of Using Prefabricated Beam Supports and Alternative Solutions

In the construction of self-built houses or industrial factory buildings, there is a long-term risk of detachment when pasting prefabricated beam supports. If prefabricated beam supports are installed through adhesive bonding or simple fixation methods, factors such as roof vibrations, temperature changes, or loads can cause the adhesive layer to age and fail over time, leading to loosening or even detachment of the beam supports and posing a threat to structural safety.
The cast-in-place method is recommended: During the construction of the roof or floor structure, set up beam support molds simultaneously and pour concrete. Cast-in-place beam supports form an integral part with the main structure, offering stronger load-bearing capacity and significantly improved durability, especially suitable for long-term load-bearing or vibration-prone environments.

II. Suggestions for Purchasing Prefabricated Beam Support Molds

If prefabricated beam support molds are required, there are various materials and styles available on the market, and choices should be made according to construction conditions:

1. PP Integrated Molds: Priced at approximately ¥11.31, they are lightweight and easy to demold, suitable for small components or temporary use. However, they have poor heat resistance and may deform when exposed to the outdoors for a long time.
2. Cement Cast-in-Place Prefabricated Molds: Priced in the range of ¥28.8 to ¥117.0, they are mostly made of steel or high-strength plastics and can be reused. They are suitable for mass production of standard-sized beam supports, and attention should be paid to matching the mold size with the roof design.
3. European-style Villa Construction Templates: Some support dropshipping and have more complex designs, suitable for decorative beam supports. However, it is necessary to confirm whether their load-bearing capacity meets the requirements of industrial factory buildings.

III. Key Considerations

1. Priority on Structural Safety: Roof beam supports need to withstand roof loads, wind loads, and possible equipment vibrations. They must be designed and calculated by professional construction teams to ensure that the cast-in-place or prefabricated solutions comply with regulations.
2. Matching of Materials and Processes: If the prefabricated method is adopted, a connection method compatible with the main structure (such as embedded part welding) should be selected instead of simple pasting. For cast-in-place construction, strict control over the concrete mix ratio and curing conditions is required.
3. Compliance Checks: Before construction, it is necessary to confirm whether the molds and materials comply with local building standards to avoid rework or safety hazards due to non-compliant materials.

Summary: Safety should be the core consideration in the construction of factory building roof beam supports, with priority given to the cast-in-place method. If prefabrication is required, professional design and reliable molds should be used to avoid high-risk practices such as pasting.
