Why in construction can not do without formwork?
Decking is a form necessary for concrete and reinforced concrete materials, which plays a very important role, because it helps to realize the design intentions and build the columns in a qualitative way. From the accuracy of the assembly of the structure, the beauty and practicality of the future column directly depends, which is why builders insist on erecting the structure directly on site.
Several decades ago, ordering formwork was a complex and expensive process, today, thanks to the possibility of using modern materials, everything passes much faster and easier, and the developer saves money without sacrificing quality.
The formwork can be round, oval, square, have a different thickness. Speaking about the height, it is worth recalling that the design is assembled on site, so you can easily adjust it.
Plastic formwork - a chance for creativity of the architect
The simplest option is the construction of plastic structures. Lightweight material can be quickly shaped to fit the necessary details. Such formwork for round columns is erected in a matter of hours, but the main disadvantage of the option is low strength.
Also plastic provides scrupulous manufacturing of parts, which means incredible accuracy in the design and manufacture of the column in the future. Good-faith docking - a guarantee of complete tightness, such an advantage can not boast of a metallic version.
Manufacturing of parts from plastic is also performed much faster, which means that the customer can receive finished items just a couple of days after the necessary drawings and parameters are provided.
How to work with plastic formwork?
During , plastic column formwork must be installed in accordance with all requirements, otherwise all the advantages of the option are reduced to "no".In order to assemble the structure, the drawings are used, all parts are executed exactly in accordance with the preset parameters of , the fastening can be carried out without additional materials due to pre-prepared "locks" in the elements themselves.
This method of constructing a structure can be compared with the assembly of a designer or laying a laminate. As a rule, firms engaged in the manufacture of formwork, offer installation services, if a person is going to do the work himself, he needs drawings and a scheme of installation. Modules can also be connected with metal locks, the recesses for which are located in plastic parts.
Ease of assembly saves time, which allows you to complete the work on erecting the column as quickly as possible. Convenient formwork for columns is disposable, made of plastic, so that it does not need to be reused. The low cost of material, the speed of manufacturing modules, the ease of installation - all this indicates that this option most closely meets the requirements of modern construction.
According to the recommendations, full concrete shrinkage occurs after 28 days, the first 7 days of plastic formwork should not be removed in order to avoid deformation of the structure.28 days - the time is approximate, largely depending on the temperature of the environment.
For general calculations, data is taken - 18 degrees above zero. Doing work on erecting a column at minus temperature is not recommended at all.
