Inventory formwork: types and installation

Inventory formwork – one of the pretty important elements in construction work. Customers must necessarily know that metal shields for monolithic construction and other options are representing. We will have to take into account the size and rules for installing overlaps do it yourself, other subtleties.

What it is?

Immediately it is necessary to indicate that the inventory formwork is a characteristic component of modern monolithic construction. When such a type of construction was just beginning to develop, had to face a large number of difficulties.

Traditional wooden shields, of course, to a certain extent got out. However, they could not be sealed by definition. The tree was quite expensive, it was possible to prepare the designs from it only manually, and it was impossible to reuse such types of formwork.

Proper inventory formwork can be applied many times without the slightest difficulties with quality. Installation occurs very quickly, which simplifies one of the most difficult works. The fixation of the shields does not bear special problems. Such shields can be fastened (regardless of size) for any possible face. Sometimes they collect blocks and panels.


Inventory formwork is needed for monolithic construction primarily because it allows you to cast good solid monoliths. The design can affect:

  • geometric parameters;

  • invoice;

  • Spatial location of elements.

Formwork is used for:

  • erection of vertical structures of buildings and structures;

  • concreting of large-sized and massive structures;

  • concreting of differentty designs;

  • Fill foundations.

Views and sizes

A variety of tasks solved by inventory formwork causes her specialization. Large and small models are usually suitable for permutation. The mass of the design is at least 50 kg. Also known:

  • lifting-stop modifications that are needed to obtain elements of a variable diameter;

  • volume-stop (they are needed when pouring wall or overlap);

  • Block versions of inventory formwork (needed for separate fragments and for large-sized plug blocks);

  • Tunnel formwork with horizontal movement (used not only in the arrangement of tunnels, but also in the construction of water pipes, tanks);

  • Pneumatic group of inventory formwork – one of the ultra-modern species, which allows you to significantly simplify the construction of the buildings of the curvilinear configuration.

Envelope, of course, is no less important than the type. The width of the shield varies from 0.25 to 2.4 m. The height is usually limited to 3.3 m. Higher designs stipulate individually or even give a special order. Linear parameters are highly dependent on the material; So, the largest size has light plastic structures.


Undoubtedly, the classic of formwork is metal shields. With all the achievements of modern construction, it will not be equal to the prevalence for a long time. For the manufacture of a shield most often used steel thickness up to 0.2 mm.

Thirdly metal is used only as needed. Steel relatively just bends, but it stands very inexpensively.

Wooden inventory formwork applied extremely rarely. Little of, Many specialists doubt whether it can generally be inventory in its level. Plastic models are usually used if the height of a single design is more than 4 m. Of course, every object is all individually. And therefore, it is necessary to consult with experts before ordering.

Installation with your own hands

Inventory formwork of overlaps – and other designs is also – always carried out strictly by calculation. Perimeter strapping leads with drills and dowels. The accuracy of geometry is controlled using the rule or level. The right lines stretch the cord. Marks can be installed on the stationery marker.

It must be remembered that the table should be exhibited very carefully. Even excess of the load for one only racks can lead to the destruction of the entire assembly. The step of installation of the dowels is 50-80 cm. IMPORTANT: Racks will not support, these are just pointers when mounting walls and overlaps. Next, you need to pull these racks to the desired length and fasten using the lock or special emphasis.

Rack elements put with such a calculation so that they correspond to all the premises created. On 1 line of the Rigel should have 3 racks. The beams should be inserted into the uniforms in accordance with the length of the riglels. The relief overlap is 30 cm.
