pu sandwich panels are widely used in factories, warehouses, and road projects. They have the advantages of high strength, good fire and flame resistance, easy installation, and low cost. So, how to edge the polyurethane sandwich panel?
How to edge the polyurethane sandwich panel?
Aluminum alloy can be used for edging, or the remaining part of color steel plate can be used for edging. When processing the edging, first determine the length, width, angle and other dimensions of the polyurethane sandwich panel; secondly, make the edging material into corresponding accessories; then use waterproof rivets to fix the edging material.
How to install polyurethane sandwich panels?
Self-tapping screws can be used to penetrate the wall panel and directly fixed to the wall substructure in this way. We can also use self-tapping screws through the connectors to indirectly connect with the wall substructure in this way. Generally, the precision related to the installation of curtain wall panels is stipulated as follows: its verticality of the facade is 2mm, and its surface flatness is stipulated to be 3mm. In addition, the seam straightness is 0.5 mm, and the installation must be carried out in accordance with the factory's regulations.
What should be paid attention to in the construction of polyurethane sandwich panels?
1. Check the size mark on the construction drawing first, and check whether the size of the construction location is consistent with the drawing ratio. When checking the size, the local size deviation should not be greater than or less than 25 mm, and the wall base height deviation should not be greater or less than 10 mm.
2. When handling materials, take corresponding protective measures to avoid collisions and damages during transportation. When unloading materials, they should be placed at various construction points, and they should be handled with care to prevent damage to the materials. After the materials are placed neatly, carefully check the appearance, size, welding, and connection quality of the materials.
3. Refer to the dimensions and requirements of the drawings, use expansion screws and other accessories to firmly fix the chassis iron, and then assemble the color steel clips. When assembling, all screws must be tightened, and at the same time, it is necessary to check whether their steel beams are in the vertical direction, whether they are in the same plane, and whether their component dimensions meet the relevant requirements.
4. When installing, make sure that the ground and the board surface are flat, and the structure design between the walls, ground, and ceiling should be reasonable, so as to ensure the tightness of the installation. During installation, if there is a corner, it should be treated as a rounded corner.
