1, which can be installed beside the column, but be careful not to interrupt the reinforcement in the column when drilling the anchor bolt hole; The crib is made to prevent the door from hitting the wall when opening the door; The battlements protected the door.

2. When the wall turns or a door hole is opened on a thin T-shaped wall, in order to facilitate the placement of the door frame and ensure the stability of the wall, a door crib should be set at the corner of the door against the wall or at one side of the T-shaped wall. The size of the door crib is generally 120mm, 240mm or consistent with the modulus of the block used. When the wall bears concentrated load or the stability of the wall itself does not meet the requirements, a pilaster can be added at the appropriate position of the wall, and the size of the pilaster should conform to the modulus of the brick.

3. First, install the door frame. This threshold is measured and set in advance. Put the door frame at the door, usually on the side where the door leaf is installed. And use an impact drill to drill holes and install 2 expansion screws.

4. Measure the width of the door frame up and down with a tape measure to the nearest millimeter.

5. Then drill the installation hole, use the expansion screw to pass through the door frame, add two inclined wooden wedges behind the door frame appropriately, measure the same width with a tape measure, and achieve the appropriate width by adjusting the length of the inclined wooden wedges.

6. After tightening the two expansion screws, you can put the door leaf in the door frame to see if the size is appropriate. And the hinge is installed on the door frame.

7, in order to facilitate the installation, you can use a marker to make a mark. Generally, just remember the location of a hole first. Punch holes with a pistol drill.

8. Align the hinge in a good position, drive in rivets with a rivet gun, fix the hinge, then punch a second hole in the hinge and install the rivets.

9. Install the hinge under the door frame in the same step. After the installation of the two hinges is completed, put the door leaf into the door frame, and move the door leaf according to the installation position of the hinges to achieve the best installation position. If the door leaf is short, it can be supported by an inclined head at the bottom of the door leaf.

10, after the position is appropriate, use a marker to locate the hinge screw mounting hole. Then drill a hole with a pistol and add rivets with a rivet gun. Open the door to see if the action is flexible, and then complete the rivet installation of the remaining holes.

1 1. Finally, punch and install the bolt hole of the door lock.
