Thick partition wall 1/4 horizontally reinforced bricks: a) view of part of the wall, b) vertical section.
Brick partition walls are made of solid ceramic bricks, i-holes, checkered, sawdust, hollow ceramic and concrete gypsum boards and others. Depending on the purpose of the rooms, the wall thickness is from 1/4 do 1/2 bricks, a with two-sided plaster from 9 do 15 cm.
Thick walls are most often used within the same apartment 1/4 bricks. If the wall area is greater than 10 m2 or the wall length exceeds 4,5 m, then it should be reinforced with flat bar reinforcement (stave) or round bars with a diameter 6 mm. This reinforcement is what 3 or 4 horizontal joints and bolts in vertical grooves of perpendicular walls.
Brick walls with a thickness 1/2 bricks are used in these cases, where greater stiffness is required. Due to the greater weight of such a wall, it should be placed either on separate ceiling beams, or on appropriately reinforced ribs. For bricklaying walls with a thickness 1/4 bricks should be used cement mortar, while for walls with a thickness 1/2 bricks can be used cement or cement-lime mortar.
The walls of hollow bricks and blocks are made according to the rules applicable to the construction of walls.
The door frames are usually set simultaneously with the erection of the wall. In the case of walls made of lightweight materials, e.g.. made of particle-cement boards, door frames are fixed to the lower and upper ceilings, so that the wall does not move.
For the construction of partitions, blocks and gypsum boards are also used. Pro Monta boards with dimensions were widely used 66,7 x 50 x 8 cm. Walls made of gypsum blocks are built with the use of lime-gypsum mortar. The walls of Pro Monta boards are made with lacing, however, the first layer of boards is placed on the layer of gypsum mortar, and then the board layers are dry-installed, by connecting them with a tongue and groove.
The wall rises to the entire height of the room, leaving a gap of approx 5 mm. In such a set wall, the joints are blurred with a plaster putty. The thin gypsum mortar is forced into the holes at the points of board contact with a pump, which fills the channels formed in the panel joints and binds the wall panels.
Wall made of gypsum boards of the Pro Monta system: a) view of the wall, b) vertical section, c) horizontal cross section; 1 - holes in the covered gap under the ceiling for inserting the mortar into the joint, 2 - channels in the vertical joints of the plates, 3 - channels in the horizontal joints of the plates, 4 - a layer of gypsum mortar against the wall.
