Monolithic overlapping, is the best type of interstorey partitions. Such overlapping, has number of privileges before normal ready floor slabs. It has big thermal insulation, isolates noise and vibration better. Doing monolithic overlapping, you can be sure that this way most the best to separate the house into floors.
Instruction
1. So, before doing monolithic overlapping, it is necessary to take care of the accompanying materials. For this purpose, the following components and the equipment are necessary for you: moisture resistant plywood which will act as surface for solution filling; overlappings, (wood beam on which it is necessary to stack plywood); unifork for insert of beam in it; telescopic rack (basic means); tripod for maintenance of rack; armature, wire, concrete, the concrete pump or the crane for filling.
2. To begin overlapping filling process, it is necessary from construction of timbering. For this purpose, it is necessary to calculate the number of the equipment necessary for overlapping. It is necessary to know for sure what area of overlapping, surely consider the overlapping height because the type of rack will depend on it.
3. Determine overlapping thickness. In most cases in owner-occupied dwellings it is 15-20 cm, the type of rack and maximum load of its use will depend On thickness of overlapping. If overlapping is very heavy, there are two options of way out: to establish to thicket the cheap facilitated racks or to use heavy rack with the increased loading.
4. Now start installation of tripods and racks with uniforks, have them on perimeter. Spread ledger boards ranks at distance of 2 m, after that it is possible to put all intermediate racks. Stack crossbeams on longitudinal, keeping distance of 0.5 m from each other. Now it is possible to make flooring of plywood.
5. The next stage – linking of armature with a section about 12 mm and its laying on plywood by means of fixers (special stools) which expense has to make 4-6 pieces on 1 m². It is necessary in order that armature did not concern timbering surface.
6. Everything, it is possible to fill in concrete, it is desirable to use material of the high brand. It is necessary to fill in overlappings for once, namely the interval between portions of filling should not exceed 3 hours. After concrete is filled in, level surface trowel or the rule. Take into account weather patterns, so, if it is raining, then fresh concrete has to be covered, and if sunny weather, then moisten periodically it with water that defects in the form of cracks were not formed. Remove timbering approximately in month.
