One of the installation steps of security door: positioning. The so-called installation positioning refers to the installation position line of the auxiliary frame popped up at the hole according to the size, elevation and opening direction specified in the design drawings.
The second step of installing the security door: correct the mullion. The so-called correction mullion means that there are three braces between two mullions for positioning. After the auxiliary frame is in place, the verticality (the auxiliary frame is not vertical to the ground, it should be ≤ 2mm), levelness and diagonal should be corrected, and the adjustment should be made according to the design requirements until the installation height is consistent, the distance between the inner and outer walls is consistent, and the width of the auxiliary frame is consistent. The installation wedge is used to assist the initial positioning of the four corners of the frame.
The third step of security door installation: the connection is fixed. After the above steps are completed, it is the step of connecting and fixing. Connecting and fixing refers to welding and fixing the auxiliary frame with M 10× 10 expansion bolt or steel bar head, which must be rechecked to ensure the accurate installation size. The allowable error of frame mouth size should be ≤1.5mm, and the allowable error of diagonal should be ≤ 2.0mm. ..
The fourth step of security door installation: grouting the auxiliary frame. When grouting the auxiliary frame, after grouting, install the main frame and door leaf and make adjustments. Until the door leaf is closed, the gap should be uniform and the surface should be smooth.
