Professional Installation Guidelines for Fire-Proof Wall Construction
The installation quality of fire-proof MgO partition board directly affects the overall fire resistance of the wall. Unlike ordinary partition boards, its installation needs to follow fire protection-oriented construction principles, focusing on the tightness of board seams, the firmness of keel fixation and the corrosion resistance of accessories, to avoid fire spread through installation defects. The whole process adopts dry construction, no cement mortar is needed, which is efficient and environmentally friendly, and the construction speed is 2-3 times that of traditional fire protection brick walls.
1 Pre-Installation Preparation
Material & Tool List (based on 100㎡ fire protection wall)
Fire-proof MgO board: 105㎡ (5% cutting wastage is reserved, and the board of the same formulation and batch is selected to ensure uniform fire performance)
Light steel keel: 75/100mm vertical keel, 50mm horizontal keel (hot-dip galvanized keel is mandatory to prevent corrosion and ensure the keel's structural stability in fire)
Fasteners: Galvanized self-tapping screws (length = board thickness + 20mm), expansion bolts, rivets (all metal accessories are galvanized to avoid high-temperature melting)
Fire protection & joint treatment materials: Fire-resistant flexible putty, 50mm wide fiberglass mesh tape, fire-proof sealant (core material for fire protection wall, avoiding fire spread through board seams)
Construction tools: Dedicated board cutter, electric drill, laser level, tape measure, rubber mallet, sanding block (wet cutting is recommended for board cutting to reduce dust and avoid fire caused by dust combustion)
Pre-Installation Base Requirements
The ground and ceiling base surfaces are flat, with a flatness error ≤3mm/2m, and no cracks or loose layers; the base structure has sufficient bearing capacity to support the fire protection wall.
The construction site is well-ventilated, with no open fire and flammable materials around, to avoid fire accidents during installation; the ambient temperature is 5-35℃, and the humidity is ≤80% to prevent the board from absorbing moisture and deforming.
Mark the wall partition line with a laser level to ensure the verticality and straightness of the fire protection wall, and confirm the fire resistance limit requirement of the wall to check whether the board specification matches.
2 Step-by-Step Installation Process (Fire Protection Optimized)
Fire-Proof Keel System Installation
Fix the top and bottom galvanized keels on the ceiling and ground with expansion bolts (spacing 600mm), and ensure the keels are firmly connected to the building's main structure (concrete beam, column) to avoid falling off in fire.
Insert the vertical galvanized keels into the top and bottom keels, with a vertical spacing ≤600mm (the smaller spacing ensures the wall's structural stability and fire resistance), and fix the vertical keels with rivets.
Install horizontal reinforcing keels at the position of 1.2m from the ground and around door/window openings; add additional keels at the wall corners and connection parts with other structures to enhance the fire protection integrity of the wall.
Fire-Proof MgO Board Fixation
Cut the board according to the wall size with a dedicated cutter (wet cutting is preferred); the cut surface is smooth without burrs, and the cutting waste is collected uniformly (inorganic material, non-combustible, can be recycled).
Fix the board on the keel with galvanized self-tapping screws: the screw spacing is 150mm at the board edge and 300mm in the board center; the screw is 50mm away from the board corner (avoid stress concentration and cracking), and the screw is sunk 0.5-1mm into the board surface (do not penetrate the fiberglass mesh to avoid damaging the fire-resistant skeleton).
Fix the board from the center to the edge to release internal stress; the straight edge board leaves a 3mm gap (for thermal expansion and contraction), and the tongue-and-groove board is spliced tightly without gaps.
Fire Protection Joint Treatment (Core Step)
First layer: Fill the board seams and screw holes with fire-resistant flexible putty, and embed the fiberglass mesh tape in the putty (the tape extends 25mm to both sides of the seam) to seal the gaps and prevent fire from spreading through the seams.
Second layer: Apply a thin layer of fire-resistant putty on the mesh tape to make it flush with the board surface; after the putty is completely dry (24h), sand it smooth with a sanding block to ensure the surface is flat.
For the wall corners and the connection parts with doors/windows, seal all gaps with fire-proof sealant to form a closed fire protection system for the entire wall.
Surface Finishing (Fire Protection Compatible)
The surface of the fire-proof MgO board can be matched with various finishing materials that meet fire protection requirements: latex paint (fire-retardant grade), wallpaper (B1 grade fire-proof), ceramic tiles (inorganic non-combustible) and veneer (fire-retardant treated).
For tile pasting: Apply an interface agent on the board surface first to improve the adhesion; for latex paint/wallpaper: apply 2-3 coats of fire-resistant putty on the entire board surface and sand it smooth, then do the finishing construction.
For humid fire protection walls (bathrooms, kitchens): Apply a fire-resistant waterproof primer before finishing to realize the integration of fire protection and waterproofing.
3 Key Fire Protection Installation Notes
No Open Fire During Construction: Prohibit welding and open fire operations near the construction site; if necessary, set up fire isolation measures to avoid the board being damaged by high temperature and losing fire performance.
Avoid Board Grooving: Do not cut large grooves on the board for laying electrical conduits; pre-reserve the conduit space between the keels, and use fire-proof casing for the conduits to prevent fire from spreading along the conduits.
Humid Area Protection: For fire protection walls in humid areas, the bottom of the board is 10mm above the ground to prevent water seepage; all board seams and screw holes are sealed with fire-proof and waterproof sealant to avoid the board absorbing moisture and degrading fire performance.
Wall Connection Fire Protection: The connection between the fire-proof MgO wall and the building's concrete beam, column and other structures is sealed with fire-proof rock wool and fire-proof sealant to eliminate fire gaps.
