Detailed instructions for the construction of the formwork for the foundation

This construction design is used in cases where the foundation structures (aerial part) is made of a curable material (eg, a concrete solution).As it is visible, then its surface increased requirements.Consequently, the smoother will be the inside of the casing, so you will need less effort for final finishing of the foundation.

In order to make the formwork for the foundation is traditionally used metal or wood (boards, plywood sheets).A new view of the "fence" is a non-removable made of polystyrene foam structure.You can buy ready-made metal parts and from which the formwork is going.Still, in most cases, individual building used wood."Private traders", tend to make the foundation of the belt type, so the formwork is constructed removable.

sequence for construction formwork

operations Preparing playground

In the area of ​​the trench must be removed all debris and level the surface of the earth as much as possible.This is necessary to install a smooth formwork.

shields Manufacturing

bars, which the board will run off into a whole, it is better to focus on one end.Then they will effortlessly enter the land.The recommended distance between - about 1 m, but when thin boards, the bars must be arranged more..The length of the bars is selected from such a calculation that after installing panels at the place they held tight.And you need to shoot down the board so that the nail heads (screws) have been on the inside formwork.

Install shields in place (along the trench)

At their disposal is necessary to observe the parallelism.To do this, you can use an ordinary plumb.

Bond boards together

It gives the whole rigidity and ensures the quality of the formwork.After the boards have to endure a heavy load at a solution casting (can read, in what proportion it to prepare for the foundation), and they can "disperse".With bars board shields on opposite sides of the trench are bonded to each other.This is controlled by the distance between the shields.

addition to hold panels in a fixed position to them "puts" props (struts).The edge of the strut, which rests on the ground must be secured (eg, peg), to brace not "gone."

To reduce the cost of work used second-class board.Therefore it is better to put the inside of the casing with roofing material.Even the gap between the boards do not degrade the quality of the future foundation.

This is the simplest version of the formwork used in a small building, and affordable to every novice homeowner.
