Fixed timbering from expanded polystyrene - the basis for the walls , accessible , even a novice

non-removable polystyrene formwork - what is it?

Fixed timbering foam is a structure into which a reinforcement and concrete is poured.Its body is made of foam blocks, connected by a special jumper.This method of construction of the walls greatly simplifies the construction works as formwork itself has the necessary parameters and additional sound and heat insulation is required.

As building material polystyrene foam is highly durable, chemically active, not afraid of water and is harmless to health.With its low weight, formwork blocks allow when working with them to do without special equipment, which also reduces the cost of construction.

In manufacturing units in their composition flame retardant is added, thereby increasing the fire safety of the building.Removable polystyrene formwork differs extraordinary simplicity of design, and its structure to easily handle even a layman.It is only necessary attention and accuracy in work.

fixed timbering from foam: proceed to the installation

As in the conventional case, formwork is set to cover a waterproofing material foundation.The only difference is that the shuttering blocks strung on coming out of the foundation reinforcement bars.When laying the first row requires attention because of its contours must indicate the place provided for the project are allocated to the internal partitions.

Once the first row is laid in grooves in the blocks overlap stacked horizontal valves, which stretches between themselves and with vertical bars connected to wire bind.

When laying polystyrene blocks should shift the rows relative to one another to give the structure the necessary rigidity.Vertical connection between the units is carried out by means of locks placed on their surface in the form of grooves and holes, securely connects when lightly pressed.

fixed timbering from expanded polystyrene: pour concrete

After the laying of the third and fourth row you can start pouring concrete . It should monitor the filling of all the cavities, carefully sealing solution deep vibrators with short working part.You can perform this procedure manually with the help of reinforcement pieces of suitable length.

when filling formwork in several layers of the top row of blocks is filled only half, ie,in such a way that the surface of hardened concrete was approximately in the middle of the top row.It should be noted that the optimal speed of the concrete work - the layer thickness meter per day.This is determined by the solution of the complete set.The bearing capacity of the walls depends on the class of reinforcement and concrete brand.

During the construction of monolithic walls should provide mounting holes for laying cables, pipes and all kinds of engineering structures.Even better, all communications take place before the concrete is poured.

incision erected the wall in such a way resembles a "sandwich" - reinforced concrete between two rows of styrofoam.And its outer layer thicker than the inner, which provides excellent thermal insulation.

This innovative construction method increasingly used by our experts, every day getting more and more widespread.In this article we have touched only basic aspects, and gives more detailed information about what is fixed timbering from expanded polystyrene, video will introduce you to new details.
