Description

Echal plates for the production of concrete works » especially fair-faced concrete plant

The object of the innovation is a plastic fichal plate, which made it possible to quickly create formwork for the production of concrete works, especially fair-faced concrete works

Due to the change of style that has taken place in recent years Architecture is always the use of concrete as a building element

moved more to the fore. ΊΓor alTea is "it" the ' ~ & e =

design form of modern architecture, the large, representative Buildings concrete used in the shape of Siohtbötön, and thus achieved great artistic effects until recently. It is the generally accepted opinion that that fair-faced concrete will be used as a design element in the future, artistic Expression medium and out of purely economic irwSgungea will play an ever greater role "

However, so far has not yet succeeded »4 the high. 0cJi§lungB-costs » associated with the production of the exposed concrete, aurüok lead to one economic borrowed height.

In the production method used since then, for example, «a normal exposure to the sun then covered with wood fiber boards; * However, Eola fiber panels are used multiple times

Another method of creation uses ge ~ planed shuttering boards, which, however, quickly became smooth Lose surface, are very expensive and in concrete but leave individual board marks.

Occasionally one has already tried with Sohal plates made of metal, e.g. aluminum, but without exception these attempts have been extremely costly, gana of them apart from the fact that the dead weight of this formwork is uneconomically high ο

The hiring sets itself the task of creating formwork for the production of exposed concrete that can be used many times over is * enables quick shuttering and stripping * a low one ElgengSÄöKrf owns »is also reasonably priced, tm can also be used for other formworksweoke.

According to the innovation, this task is made possible by formwork to loosen individual soal plates made of plastic,

If necessary, the formwork panels are made with reinforcement a reinforced plastics, have a hard, scratch-resistant surface & are used for greater surface stability with VerBt & rtamgs » ribs »the one transverse and longitudinal atablit oil! against Yea? - * Ensure security and deformation under load.

In order to enable every plan to be interpreted, ssweok wise © Formwork panels in eo different stomachs and widths manufactured »that practically no surface cannot be laid out ·

In order to secure a fastening when shuttering a non-horizontal plate allow the individual formwork panels to be la

Allow panels with stilts on the formwork beams.

Because the formwork panels have an extremely low weight have a saving in support material through them; possible »The low adhesion of the concrete to the slabs is permitted a quick cleaning of the formwork after use with a smooth broad spatula.
