With the construction of modern buildings of suburban their future ownersoften have to manufacture their own intermediate floors.However, before making the overlap between floors, it is strongly recommended that all acquainted with the technology of their construction.
device intermediate floors
subject of our review are the floor slabs, the choice of which must take into account the strength and durability of the structure is prepared.At the same time as additional requirements for facilities of this class are usually considered the following characteristics:
- insulating properties of overlap;
- soundproofing between floors;
- resistance to fire.
However, the main condition for the effectiveness of ceiling remains high strength structure provides the opportunity to finish ceilings and reducing the probability of occurrence on them of cracks and o
When assessing the merits of interfloor constructions emphasizes course of their acoustic properties.If you have a project in areas with high humidity (bathroom, for example), an additional advantage may be the presence of waterproofing.
By way of its mounting all the designs in this class can be divided into beam ceilings and floors are monolithic type.
Covering beam type
scheme with wood-beamed ceilings
beam structure produced by metal, wood or concrete beams with their subsequent finishing all the necessary elements overlap.Consider each of these categories in more detail.
Overlapping design manufactured on the basis of wooden beams, are the most common type of floors in private construction.This popularity of the following reasons:
- ease floors, made from "business" types of wood;
- simplicity and ease of installation of the beams;
- possibility to dispense with the use of special equipment (hoist or crane).
Selection section of wooden beams on consideration of the optimal ratio of their sides (usually - 7: 5).In between them is a sound and heat-insulating material to be placed directly on the so-called "hem", which is at the same time to lower the ceiling of the room.In addition, for the protection of structural elements of fire, as well as to prolong their operation should be carried out by treatment with appropriate protective compounds.
Construction floor decks
in masonry must be provided special niches in which the beams are fastened with anchor bolts of suitable size.All subsequent operations are performed in the following order:
- directly on the "hem" laid a layer of insulation consisting of mineral wool or other lightweight insulated material;
- then waterproofing layer is laid, which can perform the function of an ordinary polyethylene film;
- done inking over the beams, consisting of rough and finish the floor, on top of which is usually closed with plywood.
Due to its durability, metal beams have smaller dimensions and allows to save on the total volume occupied by the overlapping.At the same time significantly increases the load-bearing capacity of structures, surpassing the figure for the wooden beams many times.But before making the overlap between the floors of metal you should be aware that the last are not without certain drawbacks, the main ones are the low corrosion protection and the inability to provide the required level of sound insulation.
or solid beamless ceilings are usually made of materials of homogeneous structure in the form of slabs or precast (prefabricated monolithic) panels.For products in this class include the classic concrete slabs, stacked on top of load-bearing walls and partitions of buildings.

The disadvantages of monolithic slabs should include the need to attract qualified personnel and special access equipment.
To calculate the number of beams used special programs, how to use them, see below:
