According to the introduction of some explosion-proof door manufacturers, understanding the installation methods or steps of explosion-proof doors is crucial to ensuring the smooth installation of explosion-proof doors and ensuring their due The explosion-proof effect is also of positive significance. As the type of explosion-proof door with the largest share in the explosion-proof door market, steel explosion-proof doors are how to install them? Let’s take a brief look at them below.

According to a well-known explosion-proof door manufacturer, the installation of steel explosion-proof doors should be carried out in a reasonable installation sequence, which can be divided into eight steps, namely

First Step: Find a suitable installation location for steel explosion-proof doors and confirm it.

Step 2: Strictly follow the construction process requirements for the installation of explosion-proof doors, pour a concrete wall at the installation position of the steel explosion-proof door, and install the embedded parts to prepare for the installation of the explosion-proof door frame.

Step 3: Place the steel explosion-proof door near the pre-installation position, and remove the explosion-proof door leaf from the door frame. The specific operation method of this step is generally to first place the steel explosion-proof door body flat on the ground support frame, keep the door leaf open in a horizontal state, and then use a cross lift or other tools to unscrew the hinge screws on one side of the explosion-proof door frame. , and finally remove the door leaf from the door frame intact. During this process, it is necessary to avoid knocking the door leaf and maintain the integrity of the explosion-proof door.

Step 4: Mark and position the location of the pre-installed steel explosion-proof door. In particular, measure the height of the fixing bolt hole and determine the reference height of the door frame installation. And confirm the opening direction of the steel explosion-proof door, measure the installation position line of the steel explosion-proof door at the positioned position, and make corresponding markings. You can draw the fixed position line of the expansion bolt on the side of the door frame.

Step 5: Install the door frame of the steel explosion-proof door, drill expansion bolt holes in the alley, and install the bolts into the holes to fix the door frame and ensure the quality of the door frame on the wall. After the door frame is installed on the wall, according to the installation position line and the height reference line, use a wooden wedge to place the door frame initially, and use a pendant to measure the verticality of the front and side of the door frame, and make adjustments. The height deviation should not be less than 3mm, and use a steel tape measure to measure it. The diagonal length difference of the door frame should be adjusted to no less than 3mm. After the door frame is in place, you mustHorizontal and vertical, and welded firmly at the same time.
