Installation of the door block

In order to put the front door, a box set in the doorway is created. For this, wooden boards are usually used, with dimensions 50-60mm-thickness, 100mm-width. These sizes are indicated provided that the house in which doors are installed, brick or stone. Boards are processed in a certain way, undergoing preparation. When all the components passed it, they are attached with spikes. In this case, the angle between the boards should be 90 degrees. When installing, you need to pay special attention to the position of the side, lower and upper boards. They must be parallel to each other. Lower and upper should be exactly in a horizontal position. The laterals should be exactly in vertical. After this is achieved, the box is fixed. Steel pins or long nails are used as fasteners. Passing through the thickness of the box, they are driven into the wall. So that the wall becomes a support for attaching the door frame. Please note that there are cases when preliminary preparation for pins or nails is required. This is when it is impossible to gain a nail or a pin in the wall with simple driving. After all, the walls of brick or concrete nails and pins will not be able to break through. The workpiece is as follows. Calculate the mounting places and where they will be, holes are made by a drill of the necessary depth and diameter. Trucks made of wood are installed inside the holes. As a result, a nail or pin will be driven into these traffic jams, and they will retain these fasteners under strong pressure. Relative to the thresholds. Usually they are only at the front doors. As well as in the opening of the door passage between the cold rooms and warm. Cold rooms are understood as premises that do not have heat supply, but under the warm, on the contrary. There is an option for a threshold where the floor level in the room is made higher by 2-3 cm than the floor level in the corridor. This option concerns the installation of internal doors. Their box is lightweight, which is explained by the presence of three bars. The lower threshold is excluded. In turn, the box of external doors of bars four. The system of attaching external doors also differs from internal. Fasteners here are thick nails. The narrow space that arose between the wall and the box is hidden due to the platbands. When all the installation work is finished, you can go to the door itself. The door is measured relative to the box. The coincidence of their size is established. Excess is removed from the end side. The control check will be achieved by hanging on the loops. With a new detection of excesses, the procedure is repeated. Loops consist of halves and rod. They must correspond exactly in size. They are planted on screws. Screws, in turn, should fit tightly to the hole in the loop. There are two types of loop. So -called hinge and hemisphere. Hinge are divided into deaf and removable. Half -muffled are only removable. Removable are called such loops, a rod that can be removed.
