Fire door is the life channel, the installation of good or bad determines the use of life, so it is necessary to share the correct specification of the installation method.
Fire door according to the material points: a steel fire doors and wooden fire doors of these two kinds of fire doors in the installation method has some details on the different. From the fire level is also slightly different in the installation of the time must pay attention to the details.
First, the wooden fire door in the installation, the door frame size should be less than the hole 20mm, the door under the foot buried under the ground 20mm. Door frame should be fixed with the wall firmly, vertical through angle. Li Tang, holding the Tang should be strict attention to the same angle, to avoid the planing saw. Door frame on both sides of the fixed point of not less than 3, the spacing is best not more than 800mm.
Second, the steel fire door in the installation process, taking into account the door frame bending deformation of this problem, in the direction of the width of the door frame with wood Fang support up, the door frame foot buried under the ground 20mm, then the door frame and the wall of the embedded parts welding. And then in the corner of the door on the corner of the hole, pouring cement, sand, expanded perlite (1: 2: 5) concrete, and other concrete can be used after solidification.
Fire doors have closed requirements:
National standards on the fire door at the junction of the size of the gap has a clear requirement: the steel fire door, requiring its fan and door frame overlap shall not be less than 10mm, fan and the door between the two sides of the gap shall not be greater than 4mm. Fire doors installed after the closure of the gap can not be too large, otherwise the fire door sealing performance is difficult to guarantee, it is difficult to reflect its fire conditions to suppress the spread of fire and smoke.
Therefore, the to install the gap width must be strictly controlled. According to these standards to install, to a certain extent, to ensure the effective role of fire doors, consumers in the construction of the construction unit must be in the side of the supervision, to prevent them from jerry and other issues, so that the fire door will not fire Causing casualties.
