2. Code for construction of coating engineering: 1. Before coating construction, the base should be dry and clean, and the putty used in the project should meet the engineering requirements, and pulverization, peeling and cracking are not allowed. 2. The coating construction must be strictly controlled, and it is advisable not to flow or show brush marks, and it is not allowed to be diluted arbitrarily, so as not to affect the surface quality. 3. The coating surface should be smooth and uniform in color, and peeling, peeling, brush leakage, spotting, rust and spots are strictly prohibited. 4. Wood surface coating construction, according to the requirements of fire protection code, the surface of the electrical pipeline laid in the partition wall near the fire source should be painted with fire retardant coating. 5. During the coating construction, the site should be equipped with fire-fighting equipment (fire extinguishers, fire-fighting sand, etc.). ).
3. Code for construction of glass engineering: 1. In order to ensure personal safety, safety glass should be used for entrances and exits, tempered glass with a thickness of not less than 10 mm should be used for frameless glass, and semi-tempered glass with a frame glass of less than 0.5m2, protective facilities on both sides of the glass or a glass thickness of not more than 10mm can be used. Glass installation must be smooth, firm, not loose, no cracks, missing corners and other phenomena. 3. The batten is closely flush with the trimming edge, the cutting angle is neat and smooth, the connection is tight, the nail cap is not exposed, the sealing strip is in close contact with the glass and the notch, and the paste is firm. 4. After the glass is in place, it should be placed in the center of the tank, and the gap between the inside and outside should not be greater than 2mm, so as to avoid the displacement and damage of the glass due to the large gap when it is squeezed. When fixing the glass with bolts or hooks, rubber or cushion should be used to prevent the glass hole from being damaged and broken.
4. Suspended ceiling construction 1. All suspended ceilings are absolutely forbidden to be fixed on the grape racks in shopping malls and the original pipes and equipment. 2. All suspended ceilings must be made of incombustible materials such as light steel keel and plasterboard surface. 3. Flexible connections such as tapping screws or hangers should be adopted for the installation of light steel keel, and rigid connections such as electric welding are not allowed; It must be supported by metal suspenders, and it is absolutely forbidden to use iron wires and wooden sticks for support. Metal suspenders should be treated with anti-corrosion, and the suspenders and nodes have sufficient bearing capacity. It is forbidden to use upward nails or upward nails to fix suspenders. The boom spacing should be controlled at around1m. Additional keels shall be applied around tuyere holes, manholes and embedded lamps to prevent the holes from being damaged and collapsed. 4. Manholes must be reserved for the fully enclosed ceiling, and the size should be not less than 60 mm× 60 mm At the same time, according to the fire protection requirements, the fire spray head and smoke temperature sensing probe must be moved under the ceiling.
