How to make the formwork for the fence correctly ?

formwork under the fence - collect material

Formwork fence is a system of elements that create a durable, impermeable frame that allows you to build a reinforced concrete structure.Formwork itself is of several types: wall (vertical surface), Ceiling (horizontal structures), architecture (for complex structural elements), vertical (creation of sloping surfaces).

Home formwork under the fence is required to meet several requirements: to ensure smooth faces of the future concrete to withstand the growing mass and it does not bend.

not forget that it should be easy to install and also easy to remove.Professionals use expensive options, and houses can be made from simple formwork boards, metal sheets or thick plywood.It all depends on the desired height above the ground base.

It is important not to rush and install reinforcing elements as often as possible.It is advisable to pre-select the board to increase, the board for a bunch of the whole structure and the very plywood or metal sheets.

reinforcing bars is desirable to take a cross-section 50x50 mm board size for a bunch ideally looks like 50h20 mm, but the suit and others.Also set aside plywood, dense, with no cracks or bends.Suitable plywood width of 1.5 cm and above, with a thinner may be a problem.

Formwork fence - mark up territory

Having decided to make the casing with your hands, you save a decent amount of personal funds.After the preparation of the base material (boards and plywood) need to determine the size of the future concrete.For example, it rises above the ground is 30 cm, and its width is 20 cm. Depth is determined by themselves, in the case of the formwork is not so important.

Next rascherchivaem using thread or shovel future border fence.After that, we can begin to install the formwork.First fasten the bars.Lie down, they vertically deep into the ground for at least 50 centimeters, and to rise above the ground, they have at least 40 cm.

These bars have every 120 centimeters on the one hand, and on the opposite trying to drive them so that they lay down in the middle of twoalready installed on the other side.Thus, the distance between two opposite bars is 60 centimeters.Small distortions and discrepancies - it does not matter, most importantly durable design.

How to make the formwork for the fence - the final chord

It is time for plywood, cut into it so high it had no more than 40 centimeters.As for the length, the more - the more convenient.Use the screwdriver and screws fasten the plywood so that the gap between the bottom sheet and there was no land at all, or make it to a minimum.Strongly tighten the fasteners do not need to, under the weight of the concrete all will fall into place.

Naturally, plywood mounted on the inside of the pit, and bars are located behind the sheet.This gives us a maximum straight face.Do not hurry to make both internal and external formwork.

After installing the bearing bars and fixing them to the plywood, using planks size 50h20 mm bars are fastened together.Here's how: general plane down on the two opposite the bar and set the board on an incline of 45 degrees on each side is screwed by two self-tapping screws.This is done necessarily, because we need to get concrete with smooth edges.Assembly came to an end, you can begin to fill.
