What are the two methods of installing a wood door frame? What are the points of construction?

The installation of doors and windows according to the construction method is divided into two kinds of after the plug mouth and first standing mouth.

①Plug mouth (also known as plug gage): is in the wall is good and then install the door frame. Using this method, the width of the hole should be wider than the door frame 20 ~ 30mm, the height of the door frame than 10 ~ 20mm high. doorway on both sides of the brick wall every 500 ~ 600mm pre-buried wooden bricks or notch, in order to use round nails or cement mortar will be fixed door frame.

② standing mouth: (also known as standing gage): is in the masonry wall, that is, with the support of the first door frame and then masonry wall. Frame and wall combination is tight, but the gage and masonry process cross, the construction remains unchanged.

Wooden doors and windows are easy to install the main problems:

One is the door and window fan and frame gap, mainly planing is not allowed and door and window frames and the ground is not perpendicular to the door and window fan can be removed planing and repair to the frame and frame after reinstallation; such as door and window frames are not perpendicular to the box shims to find a straight.

The second is the poor quality of hardware installation, mainly open door hinges are not on the right, resulting in doors and windows and frames set of uneven fan. Each hinge can be first screwed down a screw, and then adjust the door and window fan and frame flatness, adjustment and repair without error and then tighten all the screws. On the screws must be straight, first into the full length of 1 / 3, and then screwed into 2 / 3, is strictly prohibited once nailed or screwed diagonally.
