The need for redevelopment or the construction of new walls inside the room often arises. Materials and technologies for the construction of interior partitions are not so much. The easiest way to build a light frame structure is from drywall, gypsum-fiber boards or other sheet material. You can also build a more solid, capital wall, for example, a brick wall. But for this, most likely, you will have to attract professional masons.
Choosing an interior partition made of cellular concrete
If you decide to build a partition with your own hands, then it is advisable to use cellular concrete blocks as the main material. It is easier to build such a wall than to lay out a brick masonry, and it will take much less time. The partition will turn out to be fire-resistant and with good sound-proofing properties, but at the same time it will be lighter than brick.
Even when planning work, it should be taken into account that the proposed redevelopment must be agreed with the local housing inspection authorities. First of all, this applies, of course, to capital solutions, implementing which can unknowingly damage the load-bearing structures of the house.
General recommendations for the construction of walls made of foam concrete
Brick and block partitions are built so that the vertical seams in the adjacent rows do not coincide. This is a general rule for masonry made of piece material, which is called the “rule of ligation of seams”.
Partitions should not be raised to the ceiling. Between the top of the partition and the ceiling, it is necessary to leave an expansion joint up to 1.5 cm, which after the masonry is finished must be filled with plastic material-sealant or mounting foam. Otherwise, after a year, especially in a new building, the partition may crack.
It is also important to properly connect the new partition to the adjacent walls. For this purpose, vertical shrouds serve, that is, small depressions into which the extreme blocks of the partition under construction are released during masonry. A simpler way to connect the partition to the walls is to use metal connecting elements.
The blocks can be placed on a regular cement-sand mortar or on a special glue. When choosing a block material, it is necessary to remember that the smoother its surface, the less glue will be needed for laying.
The practical part of the work begins with the acquisition of everything you need. You need to buy foam concrete (as in our case), glue, anchors and various construction tools. The calculation of the number of blocks is simple: knowing their side area ,we “stack” them in the wall area, subtract the openings and take them with a margin-2-3 pcs more.
Sequence of works
The first thing that begins the work on the construction of the partition is the marking. It is necessary to determine the line of passage of the partition and apply this line to the floor. The traditional method of application is chipping with a coated cord (photo 1). Today, for this purpose, you can use a more modern tool, for example, a laser level.
But this is not the end of the marking, as it also includes drawing lines on the walls and ceiling. After marking on the screed-the base of the floor-along the beaten line, lay a strip of roofing material or other material that will isolate the partition from the base (photo 2). This is necessary to improve the sound insulation. Then, a solution or glue is applied to the roofing material, as well as to the places where the block meets the wall, and the block is laid.
The masonry of the first row is given special attention, and the position of each block is carefully verified by level (photo 3). The partition is connected to the wall of the abutment by connecting elements bent at right angles. They are attached to both walls with anchors, screws with dowels or nails.
The choice of mounting depends on the materials of the wall and partition (photo 4). Work on the construction of the partition will go faster, and the seams will be neater, if you use a special trowel for applying a thin layer of mortar, which has a width equal to the width of the block (photo 5).
Keeping in mind the rule of suture dressing, the second row begins with half of the block (photo 6). It is not difficult to make it-foam concrete is a soft material, and the blocks can be easily cut into parts of the desired length with an ordinary hacksaw.
If the partition under construction will be joined to another new wall, for example, perpendicular to it, then in pre-determined places it is necessary to brace the joints of the connecting elements (photo 7) or anchors. Moreover, these connectors are sealed in the seams of each second or third row (photo 8).
