Customized prefabricated warehouse steel structure building

Before the construction of anti-corrosion building coatings for prefabricated structural design steel structure warehouses, attention must be paid to:

(1) Is the purchased prefabricated structural design steel structure warehouse anti-corrosion building coating up to standard, and is it required to spray the fire resistance rating regulations for prefabricated structural design steel structure warehouse engineering.

(2) Have the construction personnel selected for the spraying of anti-corrosion building coatings for prefabricated structural design steel structure warehouses received professional skill training.

(3) According to the selected fireproof material spraying method, special tools for construction must be prepared in advance to ensure the safety of construction policies and measures.

(4) The surface of the steel frame structure should be treated with rust prevention, and the rust prevention treatment should be clearly addressed according to the application regulations. Rust prevention treatment and its solution should comply with the relevant requirements of the current standard "Code for Construction and Acceptance of Prefabricated Structural Design Steel Structure Warehouse Engineering".

(5) The dirt on the surface of the steel frame structure should be eliminated neatly, and the gaps at their joints should be filled with fire-resistant materials or other flame-retardant materials to level the blocked side before use

Engineering construction.

How to implement it after selecting Cailiang? 1. The anti-corrosion and painting maintenance of prefabricated structure design steel structure warehouse should be carried out by a technical and professional construction team that has passed training and obtained relevant engineering qualifications. Develop strict construction plans based on project characteristics and product model selection. The physical and chemical properties of architectural coatings can be sampled and inspected according to the prescribed proportion before the construction project is carried out. Different locations should be selected on the construction site to test the polyurethane foaming characteristics of Pengzhang type fireproof paint,

2. The removal of the surface layer of the fireproof paint board should be a rigorous inspection process. Eliminate dust, iron stains, rust, vegetable oils and other chemical substances that hinder adhesion, and do a good job in rust prevention treatment of the board. The bottom layer and overall surface layer of fireproof paint should be matched with corresponding facilities, and the bottom layer of building paint should not rust stainless steel plates.

3. The thickness of the coating should meet the design value, and the connection point position should be thickened to solve the problem. The regulations for spray painting sites, metal surface treatment of prefabricated components, joint filling, architectural coating configuration, spray painting process, quality management and engineering acceptance should all comply with the requirements of the current national standard "Technical Specification for Application of Fireproof Paint in Steel Structure Warehouse for Prefabricated Structure Design" (CECS24). The thickness of the coating should be checked during construction (measured using a coating thickness gauge). If the coating has wide gaps and a large overall width, scientific research and analysis should be conducted to determine whether the processing technology is appropriate and whether the mortar mix ratio of building coatings is effective

4. The spraying of fireproof paint should grasp the mortar consistency of the building coating, the working pressure of the air compressor, and the distance between the spray nozzle and the prefabricated components during spraying. The key observation on the construction site shows that there are many scattered objects, indicating that the main parameters of the project construction are not scientific and should be adjusted. The intake of paint thinner in building coatings should not be excessive, otherwise it will reduce the normal construction viscosity of building coatings. Building coatings cannot adhere to the surface of steel frame structures.

5. During the entire construction process of building coatings, it is necessary to dry and solidify the coating foundation in the first layer before proceeding with the final layer of construction. The protective measures for architectural coatings, construction progress, and steel reinforcement protection layer should be clearly defined in accordance with the engineering construction design plan. The thickness of each application should be moderate and not suitable for excessive thickness or uneven coating to prevent harm to the quality of the coating. Strictly follow the spray painting process, and do not leave safety risks for the construction project in order to seize the construction period.

6. After the completion of the project, precise measurement of the thickness of the coating cannot be carried out alone. It is also necessary to use the visual inspection method to check the color tone, forgotten coating, and gap condition of the coating. Use a 0.75-1 kilogram hammer to lightly tap the coating to check its compressive strength, and use a 10m scale to check the coating plane
