Construction floor: the floor was laid on the soil. Cast iron reinforced concrete surfaces in theConstruction floor: the floor was laid on the soil. Cast iron reinforced concrete surfaces in theWe found several areas: reinforced concrete slab casting in the finished flooring. Ground floor, wireless beams prestressed concrete floor is mainly the structure that supports the weight, the weight was taken directly into the beam, pillar foundations, respectively, but in the construction of homes or buildings that are not very large, it may be used as plain or reinforced concrete surfaces using the finished flooring is sufficient.1. place the ground on Earth.This type of flooring, the jobs that are in the ground, such as a pedestrian. Residential buildings and structures can support the weight of heavy loads such as factory, warehouse flooring, roads, etc.Floor construction process placed on Earth.1.1 preparation of space for placing reinforcement Lower part belly along the banks, such as the Groove. The bumpy area. Reclamation and compaction must be done firmly. If the concrete slab blocking the water flow must discharge before making soil compaction. By soil compaction must be packed according to the building specified.1.2 for a building, the building should be done casting separated joints between pillars on the ground, to prevent cracking of the floor from subsidence along with working-level, as construction joints of the flooring are as follows:Intended to cause Contraction joint of concrete due to the dry-curing concrete. From the water in the concrete evaporates into the air, this causes shrinkage cracks in concrete. Making a Contraction joint force crack Born in the location designated by a general contraction joint spacing should be made every 24 to 35 times as floor slabs and divides the page into rectangular smaller pieces by a ratio of no more than 1.5 per short: 1.0, if possible, should be defined as a square.Isolation joint is seamless to make vertical parts, such as the concrete structure wall antenna can move independently from concrete structures such as flat surfaces to prevent the brace bracket caused fracturing of the structure in the long term.1.3. types of foam slabs separated, separated from the walls or beams, approximately 1.5-2.5 cm, and should give a slightly sloped down to the entrance. To drain the water from rain or cleaning.1.4 the steel should not be placed on the ground should know before paving to protect soil and water below prevents moisture from the ground-up slabs permeability.1.5. reinforcing steel placement, size, position and length of the construction. Place the iron on top to prevent cracks on surface of concrete.1.6 Installing the formwork sides floor coating with oil or varnish formwork formwork to be able to replicate, as well as the cleaning of formwork before concrete pouring.1.7 concrete, starting from the inner corner to the outer concrete share the gradual switch to swiping and dressing to the desired level.1.8 use of a concrete vibrator makes a concrete beef with all the tight dress, Pat your face smooth, beautiful.1.9 do continuous concrete curing for at least 7 days, so that the concrete can get full development.2. ground reinforced concrete cast in the2. construction characteristics, namely the construction of ground beams, or in conjunction with a construction background, pouring beams completed.2.1 construction the floor cast-in with the following steps.2.1.1 level checks rear crossbar High floor, the construction2.1.2 Installing scaffolding to the ground construction might have made with the belly girder or beam, construction may be completed before installing the floor stomach has enough strength strut can support the weight of the concrete, wood and the weight of workers operating circuit.2.1.3 deployed reinforcement beams and ground to size, position and length of the construction.2.1.4 make a beam and slab formwork strut with all strength, can be concrete pressure and find a concrete level.2.1.5 check the formwork that has a leak or a completely sealed or not. If installing the formwork. Formwork cleaning and water injection, or by pouring the cement before the concrete, to prevent the wood from water extraction, concrete.2.1.6 using concrete and concrete vibrator, concrete tight with both concrete samples to test out the compression.2.1.7 when it hardened, then 1-2 days removing the side and do the curing concrete strut parts leave again for 14 days and then unplug it.The construction of the floor with beam helps to increase the ability load check of the beams. Because the behaviour of the beams will change from a rectangle to a t or a cough.2.2 construction finished flooring. Procedure is as follows:2.2.1. There must be horizontal beams (Alignment) Tolerance is not less than ± 2 cm and the beams must be levels (Level) correctly and smooth.2.2.2 in the case of slabs with long and heavy, then there should be braced slabs to prevent deflection when installing and pouring concrete. To place the slabs that are longer than 2.00 m should have the crutches temporarily at least 1 point.2.2.3 before placing the finished slabs Builders should check and check leveling after the beams that will place the slabs to level and clean. In order to place the slabs were convenient, fast, and to prevent cracking of the floor plate. Normally, if the system is used in the construction of floors in the construction beams that support the floor plate will need to plug in the iron. Dowel before then to prevent the steel fractured because of the negative and moment increase bond strength.2.2.4 to lift the slabs to be careful because of the damage. The finished flooring comes always arranged close together as specified in the construction. To paste, it will lay draped in a short range of the beam.In the case of Hollow core slabs is similar to placing a sheet of plain. The Hollow core slabs placed without incision supported slabs
