Installation steps and precautions of fire door frame

In the fire door market, in terms of material, there is a common wood fire door besides steel fire door. Many consumers may have questions about this. They often think that wooden fire doors are very easy to burn because of their combustion-supporting properties. This is a common cognitive misunderstanding, but it is not. After a series of treatment processes, the flame retardant performance of wood fire doors is excellent, which is no less than other materials.

In order to ensure the safety of life and property as much as possible and reduce property losses, various installation specifications should be observed when installing wooden fire doors. First of all, when selecting wood fire doors, in order to ensure the quality of flame retardant treatment, the moisture content of wooden doors should be controlled below 12%, that is, the door body made of kiln-dried wood should be selected. The surface of the door body should be kept smooth and clean (it can be sanded, but there can be no traces, scratches, etc. ). In order to fix the door frame and the door body, the hardware fittings should be matching products that meet the national standards, and they should be fixed in a proper position with wood screws during installation.

Prepare all kinds of construction tools (including inspection tools and installation tools), review and inspect the door frame according to the drawings and the construction site respectively, and then continue the remaining installation work. In order to ensure the installation position of the door body, the baseline and center line of the door frame should be determined in advance and confirmed repeatedly. In the installation process, the door can be temporarily fixed with a wooden wedge, and the verticality and levelness of the four sides of the door with the ground can be compared with a plumb line or a horizontal line and a square. After confirmation, the fixing point can be fixed. When fixing the door frame, fix the concrete hole with nails, but it is forbidden to fix the red brick hole with nails. The hole should be drilled with an impact drill and then fixed with an expansion pipe.

After the completion of the construction, we should also pay attention to the protection of wooden fire doors in all aspects. For example, we should pay attention to waterproof, moisture-proof, moisture-proof and moth-proof at ordinary times; Painted wooden doors should be shockproof and scratch-proof, so as not to damage the flame retardant performance of the doors. Painted parts should be painted in time, and the damage caused should be repaired in time. If it is necessary to continue the construction of other projects after the installation of the fire door, the fire door can be reliably packaged first to avoid other engineering operations on the door frame.

The above are the precautions in the installation process of fire doors introduced by Bian Xiao. Through these introductions, I also hope that everyone will have a new understanding of wooden fire doors. If a friend installs a wooden fire door at home, he should pay more attention to its installation process to ensure that its high-quality flame retardant performance will not be affected.
