What is a disposable formwork TBT

implementation of many construction and design ideas can do without everything inside buildings columns of various sections and shapes.Apply for such purposes rather complicated to install industrial monolithic demountable formwork is expensive and is not always appropriate.Manufacturers of building materials and builders have found a budget option out of these difficulties: disposable formwork for columns.Formwork "TBT" is used in the construction of all types of buildings to create a square and round columns section from 150 mm to 1200 mm, optional section, as well as the device pile-rostverkovogo foundation piles, point foundations for all types of buildings, as well as in bridge construction.
Decking TBT in concrete construction
The life of such a product design ideas incorporated in the title: formwork limiting the desired profile is established in a given project documentation site.Further, for pouring concrete columns to 4 meters can be used kneaded concrete made on the job site.For a more permanent structures, and the height of supports, installed on the "TBT" disposable formwork technology, it is permissible up to 30 m, use a special technique.The process of installing formwork "pipes" looks quite prosaic.

  1. welded and fixed reinforcing cage next column;dimensions, design characteristics, location and method of attachment to the supporting elements of the building is determined by the design specification.
  2. Set "TBT" disposable formwork columns;embodiments there may be more than one, each of them not only solves the technical problems but also the interior.We offer them to consider the example of the company's products Investsnabstroy:
    • formwork square and rectangular cross-section of 150x150 (light) up to 800x800 mm;reliable bearing supports for residential and industrial buildings;Design is so-so, but high reliability;
    • the inclusion of decorative inserts in the assembly of disposable shuttering of columns;the result is quite spectacular, textured concrete surface looks unusual, with the cost of the item itself is in a reasonable price range;
    • shuttering manufacturing for columns of different shapes;for aesthetes - the source of design solutions for builders - convenient technology to reduce the cost of their work while maintaining the quality.

Performs disposable formwork "TBT" system by layering on the winding shaft cardboard predetermined shape, waterproofing (plastic films) and strength (usually aluminum foil) with the thinnest layer of the intermediate sizing.

Disposable formwork columns TBT: benefits

People who at least once engaged in concrete work, well imagine, what problems are associated with this action.Mount and secure solution at the time of solidification of plywood panels, boards, OSB and thus achieve a high-quality surface of the finished building structure is very difficult.Practicality and ease of working with the formwork "TBT" for designers and builders can be formulated in several points:

  • easy transport: even the most robust multi-layer cardboard from which manufactured disposable formwork columns, weighs much less than plywood or other wood fences can be transportedin the open transport;in transportation have savings;formwork transportation on the open trailer
  • speed installation disposable formwork for columns;specific weight per meter, depending on the diameter, thickness and density of the material varies between 1,8-40 kg / m;It installed without the use of special equipment in virtually any room;
    Easy formwork TBT
  • height of the columns can be set in the range of 0.5 - 30 m;linear dimensions of columns of any cross-section in a wide range of cooling towers;
  • limiting diameter circular smooth columns up to 1250 mm;You agree that support more than worthy;Best shuttering wall thickness in this case is 3-15 mm (depending on the cross-sectional area and the height of structures);
  • provides perfect quality of concrete pavement, requiring minimal finishing work;the inner surface of disposable formwork "TBT" with the right design solution is not deformed, purely reproducing any form of columns;
  • additional indicators of quality: high humidity (qualitative gluing layers protects the product from internal and from external influences);better than metal counterparts insulating properties;in our climatic conditions is an important factor;
  • opportunity to fill columns almost arbitrary profile, as manufacturers are willing to perform a one-off formwork "TBT" non-standard (truncated, relief, decorative) format.Custom formwork profile

assembling and dismantling formwork

Part of its position on this issue, we have already identified, so just give a dry process data:

  1. «pulled» on reinforcement cage;the support ring is mounted on the base;the upper part is fastened to the end walls (possible coupling with anchors or other fixing elements);
  2. steel cuff, easy to move through the body casing, fixed stops;installed braces and verified by the verticality of the entire structure;
  3. concreting speed for specific cross-sections from 100 to 1250 mm will vary between 6 - 2.5 m / h;
  4. dismantling of formwork made simple pulling cord (tear the cardboard in half), followed by recycling waste;It turns quickly and environmentally correct.
