If you need to expand the opening, you can dothis is with the help of a Bulgarian. With it, you can remove the excess part of the wall, regardless of what material it is from. To narrow the opening use bricks or build a formwork and pour it with concrete. The filling should be carried out through the top of the formwork. To ensure the binding of concrete to the wall, it must make holes in which the pieces of reinforcement are put. Cement is poured into the formwork with the pieces of reinforcement placed in it, after hardening, a good bond with the main wall is obtained. When using bricks, the reinforcement must be inserted every three to four rows.

The door must be installed exactly - for thisBetween the door frame and the wall, wooden wedges are inserted. Using the building level, check the verticality of the installation. To fix the box, use anchor bolts - holes are drilled in the wall for them. After installation of a door backlashes it is necessary to blow out a mounting foam or plaster with the help of cement mortar.

Tip 2: How to Install a Doorway

When reconstructing premises, people oftenface with the installation of new doorways. It is not as easy to equip new doorways as it seems. However, this work can be done independently.

Instructions

To start over the future doorway you needto establish bearing beams. If the wall has a thickness of about 15 centimeters, then only one beam can be installed. If the thickness is more than 25 centimeters, then it is necessary to put two beams. Above the usual doorway, you can install a carrier beam or rail. The length of the supporting beam should be equal to the clearance of the doorway. Also on each side you need to add 15 centimeters. This is necessary for convenient laying in the wall. The width of the contour to be pierced in the wall must be equal to the sum of the gap in the width of the door, as well as twice the width of the box with an allowance of 4 centimeters on the plaster and various irregularities. The height of the opening is equal to the sum of the height of the door, the width of the horizontal part of the box with an allowance of 3 centimeters on the plaster and various irregularities.

The work should be conducted as follows. On the old plaster, mark the contour of the doorway, as well as the contour for placing the carrier beam above the opening itself. This contour must be applied from two sides of the wall. If the wall is a carrier and the ceiling structure is laid on it, then it is necessary to work on strengthening this structure. At a distance of 60-70 centimeters from the wall to the floor, install a pair of profile columns 15X15-18X18 centimeters. Densely under the ceiling, you need to put a bar or shelves on the columns. Then the columns need to be supported with wedges.

With the help of a chisel, beat out the grooves for stylingBearing blocks. To install two bearing blocks, it is necessary to cut out a notch from one side of the wall and from the other. They then assembled blocks. If you need to install three units, then on one side of the wall, two units are installed, and on the other, one. The grooves need to be made of the right size. The beam in them should fit without problems. Before installing the supporting beam, the underlying mortar should be placed on the cement slurry having a thickness of 4-5 millimeters. Between the masonry and the end of the beam, it is necessary to apply a composite or cement mortar. The seam between the beam and the masonry above the beam should be wedged with broken pieces of bricks.
