Fixed frame reference edge
Firstly, take the door frame on one side of the door hinge as the reference edge, and take the upper reinforcing rib on the reference edge as the reference point. Fix the reinforcing ribs of the reference point on the wall with large cement nails or explosive screws to ensure that the whole side door frame is vertical, and then fix the two rows of reinforcing ribs at the bottom.
Fasten the door frame
On one side of the door lock, align the lock tongue of the door leaf with the lock hole of the door frame, adjust the position, and then fix three rows of reinforcing ribs on the wall in turn under the condition of ensuring verticality. The installation of stainless steel security door can combine the "one" and "three" steps into one and fasten them directly with explosive screws.
Debugging door frame
Try to open and close the door to see if it is smooth, the position of the door lock is accurate and the switch is convenient. If there is a problem, it can still be adjusted in a small range, and the position has been adjusted to the ideal level.
Grouting cement
Ensure that the position of the whole door is accurate and the switch is smooth. Then, you can drill small holes in the upper and middle sections of the door frames on both sides with an impact drill, and pour cement into the door frames from these small holes to fill the left, right and upper door frames, so that the door frames are closely connected with the wall, and the door frames themselves can be very hard.
Decorate the wall
After installing the integral door, the wall around the door frame should be leveled with cement, and then the surface can be coated with paint, coating, strong paper or ceramic tile consistent with the surrounding whole.
