Follow the construction principles, according to the actual site conditions, Civil door cavity measurement - Summary - Report to Party A to confirm the construction size of the door cavity -- order production -- door frame installation position and elevation marking -- material approach to transport the door frame and door door to the installation site -- preparation of technical solutions -- construction machinery configuration -- → Vertical Fire door frame → Wooden wedge Immobilization → Re-review of the immobilization on a horizontal line The mobilization capability is mobilization. The mobilization capability is mobilization. The mobilization capability is mobilization. The mobilization capability is mobilization. The mobilization capability is mobilization.

When selecting materials, samples must be provided in accordance with the requirements of Party A and the supervisor, and formal construction can only be approved.

Check whether the size, elevation and opening direction of the door opening meet the design requirements. The door with embedded parts should also check whether the number, location and burying method of embedded parts meet the design requirements.

(3) Engineering quality standards and assurance measures

The Fire door frame should be installed before the opening is plastered and the ground is not of type. Before installation, pay attention to the opening direction of the Fire door according to the design and Fire protection requirements (in general, the opening direction of the Fire door is the evacuation direction). The Fire door should be installed after the completion of civil construction and decoration works to prevent collision and pollution of the Fire door due to cross-construction and other reasons.

1. Preparation for construction

1.1 Familiar with drawings and selected atlas for Fire door design and installation requirements.

1.2 Check the location, size, specification, quantity and grade requirements of Fire door installation.

1.3 Check the size of the hole. If the hole is too small, it should be cut out. The horizontal control line should be fired on both sides of the door frame hole.

1.4 Clean the scum and floating slurry of the installation hole.

1.5 Technical disclosure of the installation personnel, preparation of auxiliary materials and tools.

2. Door frame construction steps and standards

2.1 First, the mobilization of 0.5mm iron sheets (specifications 150-1800*350*450*0.5) has been mobilized with self-tapping screws to mobilize the door frame with a height of less than 1.5 meters, with two pieces on each side. Door frames larger than 1.5 meters and smaller than 2.1 meters, 3 pieces on each side; Door frames larger than 2.1 m, 4 pieces on each side; If the width of the door frame is less than 0.6 meters, the top and bottom of each piece; if the width of the door frame is greater than 0.6 meters and less than 1.2 meters, the top and bottom of each piece; Three pieces above and below 1.2 meters.

2.2 Check the opening direction of the Fire door, position the door frame on the hole, and use a wooden wedge to Immobilization.

2.3 Adjust the gap between the door frame and the wall of the opening and the height of the top and bottom, use the hanging hammer and the ruler (basial plate) to make the vertical and horizontal, the bottom foot of the door frame should be buried 20mm below the ground.

2.4 After correction, use cement steel nails to Immobilization the two ends of the iron at the hole of the brick wall, or use a nail gun to Immobilization the two ends of the iron sheet at the hole of the brick wall.

2.5 Check whether the installed door frame is either vertically or horizontally, or vertically or diagonally. If the deviation is within the allowable range of the specification (2-4mm), it is considered qualified before entering the next process.

3. Door construction steps and standards

3.1 The door fan can be installed only after the door frame plug joint is completed and can meet the installation requirements.

3.4 When installing Fire prevention hinges, cut grooves in the side ribs of the door, the grooves are slightly deeper than the page plate, so that the page plate will not protrude after loading. In order to make the gap above and below the door door consistent, the upper groove should be about 0.2mm deeper than the lower groove.

After the groove of the door is chiseled, the hinge plate is installed and tightened with wood screws. When the wood screw is tightened, it should not be nailed in with a hammer at one time, and should be nailed in 1/3 before screwing in. Then install the door door in the diaphragm opening, screw a wood screw into the upper and lower hinges, check the size of the gap around and adjust it properly, and then screw the other wood screws into the door one by one.

4. Basic requirements for door and hardware installation:

4.1 Hinge distance The upper and lower height of the door should be 1/10 of the height of the upright, and avoid the upper and lower flutes. Press 3 hinges on each side of the height above 2.1 meters, and press 2 hinges on each side of the height below 2.1 meters. The switch should be flexible after installation.

4.2 The door lock should not be installed at the junction of the middle riser and the upright, and the door handle should be 0.9 ~ 1.05 meters away from the ground. When the fire safety sliding gate is installed, the middle line of the sliding gate is 0.9 meters from the ground.

4.3 The size of the Fire prevention cigarette strip is 2mm thick and 1.5mm wide. The Fire prevention cigarette strip is embedded in the sealing groove with resin adhesive.

4.4 The installation of door closers should meet the requirements of the specification, usually in the direction of the evacuation direction after installation, to ensure that the opening and closing are flexible.

4.5 The dark latch is installed on the upper and lower ends of the equal fan of the split type door, and there shall be no friction between the dark latch and the cover fan after embedding.

4.6 When installing the Fire prevention glass, the glass strip must be pressed tightly, and the door door must be kept without gaps, and no loosening is allowed.
