We all know that building a house begins with building a foundation. However, the latter will be practically impossible to build unless special designs are made first.
The self-made formwork allows you to fill in a quality foundation in the required dimensions. This type of structure is used very widely in construction when pouring concrete at large construction sites. Formwork panels, which, as a rule, are prepared in advance, are mainly made of wood, but they can also be made of plywood or metal.
During the planning, the do-it-yourself formwork is knocked together at the work site. The height of the panels depends on the height of the required foundation. Basically, when assembling the frame, bars, nails, staples and screws are used. The design must be strong, because when pouring concrete, it exerts serious pressure on the box.
This construction can be not only for the foundation, do-it-yourself formwork of the ceilings is also carried out, for example, when there is a multi-story building. The installation principle is different from the foundation.
By the type of formwork, made by oneself, can be removable or non-removable. As a rule, the removable is removed immediately after the foundation has more or less settled down and gained strength. These panels can be used repeatedly in the construction of bases.
In construction, wall formwork is often done with your own hands, which is built using a separate technology. It is quite reasonable to apply it not only for casting walls from scratch, but also for repairing defective places in a structure. Today, two types of formwork are most often used:
1. Stationary.
2. Collapsible and permutable.
Stationary formwork is a structure that is assembled from individual elements. To do this, use boards of different widths, fasteners, bars. This method of building formwork is quite old, but to this day it is used in the construction of private and public buildings. Typically, the structure is prepared with spans that are needed in place and size of the foundation. The boards are attached to each other with the help of bars, which are sewn with a screw or a nail. To fix the formwork in place, use props and embroider the top with short planks. Slots that are observed in the formwork panels can be clogged with slats.
Collapsible formwork
This type already has ready-made elements that are easy to assemble and disassemble, using as a template for a new foundation.
It is used for almost any reinforced concrete work. The self-made formwork is removed at the moment when the solution begins to harden. The principle of collection is similar to the previous version.
Using these formwork methods, you can build a foundation of almost any complexity. The latter option will be convenient for those involved in the construction of custom-made. It will not be necessary to pick up boards and assemble panels every time, it will be enough only to strengthen everything in place.
