Wood fire door specification.

Wood fire door specification.
Wood fire door specification 1, “building design fire code” and other fire regulations, firewall must use non-combustible or non-combustible materials, “building interior decoration design fire code” provides that all buildings except ordinary residential wall decoration must use non-combustible or non-combustible materials. Wood fire doors as part of the firewall, in addition to fire resistance limits, it should also be difficult to burn materials. And the “wood fire door general technical conditions” on the door finish material has no requirements.
Wood fire door specification 2, “wood fire door production allowable deviation” in the door frame and door fan warping allow deviation of 3mm and 2mm, respectively, and “wood fire door installation allowable deviation” box and fan contact surface flatness allow deviation of 2mm. If the warping deviation of the door frame and the door fan is 2.5mm and 0.2mm respectively, the flatness deviation of the rear frame and the fan contact surface is greater than 2mm, which does not meet the standard requirements.
Wood fire door specification 3, by the “wood fire door production allow deviation” can be known, I. grade wood fire door height and width of the production allow deviation door frame 0/-1, door fan is 1/0. Assuming that the official size of the door fan is X, the actual size of the door fan of the I.grade product can be X to X to 1 mm, and the actual size of the inner port of the door frame can be X-1 to X mm. If the installation does not re-process the door fan or the inner port of the door frame, its fit is too hard to cooperate, the door is not closed.
By the “wood fire door installation of the seam width” can be known, the wooden fire door installation of the seam width, door fan to the mouth seam, fan and frame between the vertical seam for 1.5 to 2.5mm, the frame and the upper seam between the fan for 1.0 to 1.55mm. To ensure that the one-way slit between the fan and the frame is 1.5 to 2.5mm, the re-cutting volume of the door fan is 3.0 to 7.0mm when installed.

 

Wooden fire door acceptance specifications.
Wood fire door acceptance specification 1, wood fire door cutting angle, stitching should be strictly flat, plywood should not allow cutting through the surface plate, surface should be clean light, the coating should be uniform, flat, there should be no pile paint, bubbles, leakage and flow and other phenomena.
Wood fire door acceptance specification 2, wood fire door its hole width of 1200mm, hole height of 2100mm, door fan no glass, door frame single notch, no bright window, no lower frame door door door closed counterclockwise direction, its fire resistance time is not less than 1.00 h, fire insulation time is not less than 0.05 h double fire door.
Wood fire door acceptance specification 3, the narrowest wooden fire door in the corridor is 1.2m, power distribution room is 1.5m, small door is 0.9m to 1m, roof 1.2m to 1.5m.
Principle of wooden fire doors: Fire doors usually use firewalls, stairwell entrances or pipe well openings, which play an important role in reducing fire damage. Fire doors in high-rise civil buildings are divided into grades A, B and C, fire resistance limit Class A doors must not be less than 1.2 hours, Class B doors must not be less than 0.9 hours, Class C doors must not be less than 0.6 hours.
