Chapter 2 DEVICE PARTITIONING / Primakov Kostenko

partitions are thin internal wall. If the partitions are based on the foundation and the load they are carrying. For devices used for their material walls are wood, plaster, brick, made of light concrete, etc.

By design partitioning distinguish between solid, made from piece goods directly in place, frame and assembled from panels - panels.

Partitions should be strong, stable, have adequate heat and sound insulation. Surface walls must be smooth. When mounting the partitions, remember that they can not be installed on floors, they must rely on the beams, girders. In places ground floor with a sound-proof walls paved strip. When the device partitions into account the possibility of precipitation of the building, so in stone buildings, walls made below the ceiling of 10-15 mm, and in bruschatyh and timber - to 50 mm. This gap close up tow and mortar. Gaps in the field of contiguity walls to walls prokonopachivayut antiseptirovannoy tow soaked in alabaster solution. By the wooden partition wall nail, but to stone - steel ershami who hammered into wooden antiseptirovannye tube incorporated into the walls. Partitions can be mounted on a beam across the and along the beams.

solid walls are made mostly single. They are made from thick planks of 40-50 mm, width 100-120 mm, cohesive vertically. Board partitions fastened to the overlapping with studs, the lower rail is fixed to the joists with nails or lag.

Before installing partitions in the place where it will stand, necessary to fight off the wall cord two vertical chalk line, then sleepers, beams, ceiling mark out a line of boards installed studs septum after which are fixed with nails to the floor and ceiling of the upper and lower marking harnesses. Between the piping on the floor and ceiling forms a groove in which to insert the board partitions. In the pre-cut to size boards mark out space for the formation of holes around the spikes. Boards set vertically, bonding between is spiked with glue. The diameter of spines 10-12 mm, length 100 mm; have their height increments 1-1,4 m. To trim board partitions fastened with nails, and boards should be 10 mm shorter than the distance between the strapping.

Framed partitions consist of racks, upper and lower studs section 30-50? 50-100 mm. The frame is collected on nails on the floor and then install the assembly in place on beforehand of marked lines. Attach the frame to the stone walls ershami, were killed at predetermined wooden tube, and the wooden walls - nails. Verticality of the frame check plumb. On the whole place a deviation from vertical to 10 mm.

After reconciling vertical frame sheathe on both sides of the boards 19-25 mm thick plate materials, fibreboard, plasterboard sheets, nailing them to the frame with nails. The inner space filled with mineral wool.

Panel-panel partitions installed so. First, mark out the place setting partitions, then to the floor joists and nailed to the ceiling lower and upper thrust blocks, which must be in one vertical plane. Focusing on these blocks, set the first outermost panel, adjacent to the wall. After checking the verticality of its fastened to the wall and to beam nail length 70-90 mm, then customize it to another panel. Between a panel fastened with nails and beaten at an angle so that they got through establishing a panel (panel) in a previously installed.
