Installation slab formwork with their hands

Production of building structures made of concrete, and in particular the ceilings requires careful observance of technology at all stages.It depends on the quality and durability of the finished result.The construction of floors in the construction of the house starts with the removal of sizes and preparation of the drawing.It is important to take account of sufficient size openings for ladders, pipes, etc. CommunicationsThe first stage of work - installation of the formwork.If you mount it with distortions or other violation of the technology, you get the plate is uneven.

Materials

durable materials required for the manufacture of molds.Concrete has a lot of pressure on the design and not enough thick walls and bottom vyduyutsya or cracked.It would take:

• panels to the bottom of waterproof plywood 2 cm thick, reinforced by transverse bars, or knocked together planks 4-5 cm thick,
• crossbars thickness 5-7 cm long enough to connect the opposite walls,
• side boardsa wall thickness of 3 cm or plywood,
• old linoleum flooring or roofing material for the lining of the formwork or film for waterproofing,
• bars with stand made of boards or telescopic tripods for support,
• carpenter tool level, fasteners (corners, bolts, screws and nails).

If resources permit, the formwork can be made of plywood 2 cm thick, padded bars 1 * 1 cm. After hardening of concrete is very easily separated from it.It is convenient to use and easy to subsequently removed from the formwork OSB.The surface of all the lumber must be flat and smooth to get the same plate, and trim expenses were minimal.

easiest to work with telescopic tripod in the role of support, but they cost more.Some construction companies rent the equipment rental.It is necessary to take advantage of such offers as a single rack can be used to support the weight of 2 tons.Unlike wood, they do not crack and will not curved.

design

In fact, the design of the formwork for the slabs is a form, preferably a sealed bottom and sides, supported by the uprights.In the future, it is established a framework of reinforcing bars (best composite), poured concrete.After drying concrete formwork understands.Sex and the ground under the slab of the future should be firm, that because of his drawdowns are not disrupted plate geometry.

Initially under the future are arranged overlapping support.Do it in steps of 1-1.5 m over the entire area.They laid the cross beams are aligned by level using chocks and are bolted to the walls.They can not be laid on the walls, because after the concrete pour to remove such a structure will be problematic.Above the beams secured plywood boards or bottom which must be positioned 5 cm below the wall beams.If the coating is not integral with the slits, the further lining layer of material which will hold the concrete.

After the horizontal base is ready, mounted vertical ledges.Their height should be a few centimeters above the intended concrete layer.Level check the verticality of the walls.Particular attention is paid to corner piece, it is better to carry out by means of metal parts.

When the formwork is ready, it is necessary once again to check its horizontality, and can be installed rebar and pour concrete.
