When using galvanized fireproof iron sheet fireproof board in high-rise buildings, it is necessary to strictly follow the national and industry fire protection standards. Galvanized fireproof iron sheet fireproof board usually needs to meet the A-level standard of non-combustible materials to ensure that it does not burn or release toxic smoke in a fire.
In order to meet the fire protection needs of high-rise buildings, the material performance of galvanized fireproof iron sheet fireproof board must meet a number of mandatory indicators. In terms of the galvanized layer, it is necessary to have good rust resistance to prevent the iron sheet from reducing its strength and fire resistance due to corrosion; the core material of the fireproof board must be made of inorganic non-combustible materials, such as rock wool and glass wool, to ensure that the structural integrity can be maintained at high temperatures. In addition, the physical properties of the board, such as density, compressive strength, and water absorption, must also meet the standards. For example, the compressive strength must reach a certain value to withstand the load of the high-rise building wall, and the low water absorption rate can prevent the board from being deformed by moisture and affecting the fire protection effect.
Before installing galvanized fireproof iron sheet fireproof board, you need to be fully prepared. First, clean and inspect the construction area to ensure that the base wall is flat, dry, and free of impurities such as oil, dust, etc. that affect the bonding effect; secondly, accurately measure the wall size according to the design drawings, and reasonably plan the cutting and arrangement of the panels to avoid loose splicing due to size errors. At the same time, prepare special adhesives, fixed anchor bolts and other installation materials, and conduct technical briefings for construction personnel to clarify the installation process and quality requirements to ensure that the construction is standardized and orderly.
During the installation process, technical specifications must be strictly followed. Generally, a combination of pasting and anchoring is used. First, the adhesive is evenly applied to the wall. After the fireproof board is attached, anchor bolts are used for reinforcement to ensure that the board is tightly connected to the wall. The splicing of the panels is a weak link in fire prevention. Staggered splicing is required, and fireproof sealants are used to fill and seal the gaps to prevent flames and smoke from penetrating. For special parts such as door and window openings and pipeline crossings, enhanced treatment is required, such as adding fireproof tape around the openings to ensure the integrity and sealing of the fireproof board.
Galvanized fireproof iron sheet fireproof board needs to be installed in coordination with other fire protection facilities in high-rise buildings to form a complete fire protection system. At the intersection with fire water pipes, cable trays and other facilities, fireproof sealing materials need to be used for sealing to prevent the spread of fire; the installation of equipment such as automatic sprinkler systems and fire alarm systems needs to be planned synchronously to ensure that the fireproof board does not affect the normal operation of the facilities, and the installation of the facilities will not damage the integrity of the fireproof board, so as to achieve functional complementarity between various fire protection facilities.
After the installation is completed, strict quality acceptance is required. According to the "Code for Fire Protection Construction and Acceptance of Building Interior Decoration", the appearance quality, installation firmness, and joint gap width of the fireproof board are inspected to ensure that there are no problems such as warping, damage, and leaks. At the same time, through on-site sampling inspection, verify whether the core indicators such as the combustion performance and fire resistance limit of the board meet the design requirements. In addition, an airtight test is required to check the sealing effect between the fireproof board and the wall and facilities to ensure that smoke and flames can be effectively blocked in the event of a fire.
After being put into use, the galvanized fireproof iron sheet fireproof board needs to be regularly maintained and managed. During daily inspections, we focus on whether the surface of the panels is rusted, cracked, deformed, etc., and repair damaged parts in a timely manner; we regularly clean dust on the surface of the panels to prevent dust accumulation from affecting fire resistance. At the same time, combined with fire drills and safety inspections of high-rise buildings, we evaluate the actual effect of fireproof panels in simulated fire scenarios, summarize experience and continuously optimize to ensure that fireproof panels play an effective protective role throughout the life cycle of the building.
