4.3 wall lead protection production
1. Interior wall structure
In this project, it is proposed to add protective lead plate on the basis of the original steel structure to achieve the purpose of lead protection, and then use 4mm waterproof gypsum board and the original 1.2mm electrolytic steel plate as the facing to achieve the decorative effect.
2. Construction operation process
(1) laying lead tape: according to the size requirements of lead plate, lay lead tape on the original steel frame and fasten it with self tapping screw.
(2) lead plate laying: the lead plate cut according to the process requirements shall be laid on the lead belt, and the gap between the lead plates shall not be greater than 3mm.
(3) laying waterproof cement gypsum board: lay the waterproof cement gypsum board cut according to the process requirements on the lead board, and fasten it with self tapping screws.
(4) external decoration board laying: according to the specific situation that the electrolytic board cannot be welded with the steel structure of the project, the original electrolytic steel plate can be fixed on the wall by pasting after the internal structure is completed, and the welding between the boards is firm. The verticality of the wall panel shall be controlled by the laser level during installation.
(5) surface treatment: all cracks shall be filled with Sherwin Williams American original imported metal anti crack and anti-bacterial atomic ash for operating room. After the atomic ash is dried, it shall be polished and cleaned. Then, Sherwin Williams American original imported anti bacteria coating of the same color as the original operating room shall be used for spraying. The anti bacteria coating has passed the legal protection of the United States: LEED Building Association, EPA, the United States Environmental Protection Agency Certification as environmental protection coating, which is especially strong in anti bacteria, anti rust, anti-corrosion function, no organic solvent, no radioactive substances, water dilution, non-toxic and harmless.
(6) corner treatment: the corner between the wall and the ground shall be covered with plastic lining angle and aluminum alloy arc wrap angle, and sealed with sealant.
(7) sanitation of concealed space: dust must be cleaned at any time during the construction of wall panel installation, and image records shall be made for the cleaning of concealed space.
