What should be paid attention to in the installation of sandwich panel buildings?

Installation of wall panels, roof panels and gutters of sandwich panel buildings

• Installation of wall panels and roof panels: After the roof purlins and wall beams are installed, the color steel sandwich panels on the roof and walls can be installed. Generally, the wall sandwich panel is installed first, and then the roof color steel sandwich panel is installed to facilitate the connection of the eaves.
• Gutter installation: The inner gutter is mostly supported by stainless steel products and fixed on the side beams (purlins) of the cornice. The spacing of the support frames is about 500mm, and they are connected with bolts. In addition, the inner gutter also uses 2–3mm steel plates to press the water tank, and the inside of the water tank is coated with asphalt oil for corrosion protection. The outer gutter is mostly made of color steel plate to support and fix it on the roof panel of the cornice.

The color steel plate installation and connection method of the sandwich panel building

There are two types of color steel sandwich panels: hidden connection and self-tapping screw connection. The hidden connection fixes the color steel sandwich panels on the purlins through the brackets, and uses a mouth machine to bite the adjacent sandwich panel joints between the color steel sandwich panels in the horizontal direction, or glues them with waterproof adhesive glue, and this This connection method is only applicable to the roof. Self-tapping screw connection is to fix the color steel sandwich panel directly on the roof purlin or wall beam through self-tapping screws, and apply waterproof glue to the screw to seal. This method can be used for roof or wall color steel sandwich panel connection.

How to choose color steel plate?

1. Observe the leakage edge of the color steel plate

When we purchase color steel plates, we need to see whether the exposed sections of color steel plates are crystallized and dense. Greyish, dark, and impurities indicate poor quality, while finely crystalline cuts indicate excellent quality.

2. Observe the thickness of the substrate and the thickness of the coating

The color steel plate is composed of the base steel plate and the colored peritoneal layer, so we need to pay attention to the thickness of the substrate and the thickness of the film when purchasing. Usually, the thickness of the color steel plate with excellent quality is between 0.02 and 0.05mm, and the thickness of the peritoneal layer is between 0.02 and 0.05mm. Below 0.15mm.

3. Listen to the sound

When we buy color steel plates, we can also tap the color steel plates with fingers or hard objects and listen to the sound. Usually the sound of color steel plates with excellent materials is brighter and crisper.
