# Tip 1: How reinforced slab

This question currently asked those who at least once in a lifetime spent capital construction of a private house.It is noteworthy that just the process of reinforcement is quite simple, but for its quality performance must be thoroughly study the technology, as well as to learn the sequence and specificity of some of the steps.
Guide
1
Calculate monolithic structure overlap .Collect all of the load acting on the overlap, both permanent (own weight of the structure, the weight of materials, wall and ceiling, etc.) and time (load of people, furniture, equipment) and produces a static calculation of the structure.On the basis of the calculation to select the thickness of the monolithic slab needed reinforcement, as well as the thickness of the concrete and reinforcement scheme.
2
Form beam "skeleton", and set the formwork at the desired location.As a rule, any formwork is made of wooden boards and props (you can use pieces of wood, or boards, but given the fact that they have to support t
he weight of reinforced concrete).As for columns, then there should be at least 6-8 for each set of shields - minimal amount simply not allow to keep the entire structure, and the plane of the overlap is not so smooth, which would be desirable.
3
Follow reinforcement or use of the usual plaster grid, if the operation of the design will not operate heavy loads, or metal rods and even the old iron pipes.The process start with the installation of reinforcement on shuttering plaster grid - it is in the process of pouring concrete in addition "spoiled" the inner walls and do not give them to crumble and crack during the operation.
4
Weld iron pipes (preferably pre-cut into pieces of different sizes) to set in advance the iron beams, thus forming a kind of net and thereby to fasten the pipes iron rods every 15-20 cm mesh.After the carcass reinforcement is created, start knitting - the process, the main purpose of which is to further retention of the concrete slab during the operation.For this you can use knitting or a soft wire or the metal rods that are welded to the pipes after.
5
Fill created form concrete.It should be noted that initially fills (so-called "spilling") solution should be "liquid" to be subsequently could "move" with the shovel.Next, you need to mix a solution of "thicker" and predetermined beacons pour it into the mold.After pouring the formwork should wait until dry mixture (two to three weeks), and then remove the form and get ready to align overlapping with special mixtures.

# Tip 2: How to make a concrete slab

One of the best construction technologies overlap is considered to manufacture them using cast concrete.They performed both independently and through third-party construction companies.In any case, you should first create a project where you need to calculate all the materials.
you need
• - metal fittings;
• - boards for a flooring;
• - wooden support;
• - profiled.
Guide
1
Make a deck on which tie reinforcing mesh.Then fill it with concrete.Flooring from boards do, it should be as smooth.Set backups across the surface of the deck so that it is not forced and overlap turned out quite horizontal.If the quality is very important to the ceiling, then lay on deck waterproof plywood, laminated better.Reinforcing mesh knit so that it relied (lay) on the wall.
2
Make lateral formwork to the concrete solution was poured on the sides.For filling, use any special equipment, such as columnar trolley with retractable bottom or concrete pump, or manually.Trolley filled with concrete on the ground, then lifted by a crane and fill station.You can fill in parts.But it is necessary to ensure that the concrete mix does not dry out completely.For example, the evening ended, and in the morning went on.The thickness of the concrete layer should be about 10 cm, but may be slightly larger.
3
Use profiled as an alternative approach.However, it is only used as permanent formwork, ie the presence of corrugated board does not change and does not replace the reinforcement.To create a large-scale floors use special devices, such as vibrators.E It is used to expel the solution from the bubbles, thereby making it durable.Without this seal overlap do dangerous.Builders do not always compacted concrete vibrators, this is often done simply shovel butting between reinforcement bars.
4
Select the thickness of the concrete layer, concrete grade, thickness and reinforcement grid, based on the conditions of safety.For a thick slab, use a larger diameter valves.These parameters are calculated by special methods specified in SNIP.
