Construction scheme of artificial sandstone for external wall hanging

Answer:

Construction scheme of artificial sandstone for external wall hanging:The exterior wall decoration stone dry hanging method is to use the high strength corrosion resistant metal pendant, the decorative stone through the support, hanging, pin, bolt method is fixed on the outside surface of the building. Reasonable pendant design and construction technology is the key to ensure the safe and beautiful stone exterior.

Welding of connecting piece:The general use of embedded parts + connecting plate + stainless steel pendant "or" + + embedded connection plate steel keel + stainless steel pendant "fixed stone installation process; embedded parts have been completed in the structure construction. Ensure strong and durable embedded parts and connecting plate and the keel of the welding quality of external decorative is particularly important. For the following requirements:Cleaning the welding seam before welding, no oil or rust. Welding construction should be on behalf of the owner of the site and the supervision of the witness to take the same thickness of pre embedded plate, connecting pieces, steel, welding rod, welding current to do the same conditions of welding specimens, and sent to the quality supervision and inspection departments to detect.Two, stone installation:First according to the sample check sheet specification, after verification of plate end slotting and board installation. The following measures can be taken to ensure the quality of the groove (verticality, groove depth, slot):On site production of wooden stone fixed frame, the stone will be fixed and then slotted. Trough the upper and lower alignment T type pendant, marked position and then slotted. The depth of the groove with marble machine and the scale rod preset position, the scale rod against stone, groove depth should be 16mm. After the completion of the groove should be self - inspection, including the groove depth, position, vertical, the side of the stone is split.Stone on the wall before the first removal of floating dust in the slot, stone slag; after the test, the slot plastic injection, installation of stone, by the ruler check.

Caulking:First, with a special brush to clean up the stone seam, seam deposit, inner hysteretic pollutants, clean and brush powder, acetone water two times, in order to increase the adhesion of the sealant.The wide gap filling foam strips. Sealing strip is 10mm, filling depth should be straight uniform (from the stone plate surface 8mm), non overlapping, in Pendant disconnect joint tight meet without gap.
