On the report of the project price per square meter engineering requirements is to use 50 * 5 angle iron keel with 4mmA grade aluminum-plastic plate dry hanging
Structural adhesive material must be neutral silicone sealant, its performance must meet the requirements of the construction of silicone structural sealant GB16776 (silicone sealant must be used within the validity period) fasteners are mainly screws and self-tapping , Its material is generally stainless steel or aluminum products, fasteners to meet the design requirements, and the quality to meet the national norms and the relevant standards. Main tools (tools): welding machine, profile cutting machine, pistol drill, theodolite, level, rivet gun, self-drilling and milling machine
Main materials: aluminum-plastic composite panels, profile skeleton, embedded parts, connectors, caulking sealing materials and fasteners. Profile skeleton are: aluminum alloy frame skeleton and steel skeleton, skeleton material selection to meet the design requirements, skeleton selection specifications and materials to meet national standards and related standards. Embedded parts and connectors: skeleton anchorage generally used embedded parts or post-embedded parts, post-embedded parts to meet the design requirements, and in the field to do pull test; steel plate connector and non-homogeneous skeleton connection, the middle To pad the organic material pad, in order to avoid electrochemical corrosion.
Skeleton production and installation of aluminum-plastic composite board for the plastic layer are pressed up and down a layer of aluminum sheet, and then in the aluminum plate surface by roller coated with fluorinated vinyl resin, made by baking, aluminum plate using mechanical milling, And leave a 0.3mm thick core material, so as not to hurt the inner surface of the panel. After the cut, fold, strengthen the ribs of the security system. Install the finished parts after installation
Skeleton anchors should be made with embedded parts, in the absence of embedded parts in the case of post-embedded parts, embedded parts of the structural form to meet the design requirements, before the construction according to the project axis and the center line and the baseline level Embedded parts to check and check, the general allowable position size deviation of ± 20mm. Bolt to be carried out on-site drawing test to meet the strength requirements before use. If the location of embedded parts can not be used or leakage, should be based on the actual situation of the expansion bolts fixed post-embedded embedded parts of the program, and must be reported to the design unit approval, and should be done in the field pull test, Take good notes. The anchors are usually made up of buried plates and connecting corners, which are accurately marked on the centerline of the mullion, and then the holes are fixed and the centerline of the mullion leads to 0.8 Mm wire (both ends with the basket screw tightening) for signs control line. And then the level of the standard and the standard steel embedded parts, and then calculate the location of the connection angle code, in the buried plate on the crossed mark, the same mullion connected to the same side of the corner position to pull the line detection, can not be biased. Corner position to determine, the corner code according to this location welding to the buried floor, the width and length of the weld to meet the design requirements, welding after welding to do rust treatment, the general brushing antirust paint twice.
