Abstract

The bottom flanges are perforated and covered with a porous material such as felt or a mineral wool panel. The porous material absorbs moisture from the cast concrete and directs it towards the slab perforations, from where it is released into the atmosphere.

Description

31 1: Illlz; 510 519 Underflänsama 12 är perforerade genom att rader med korta slitsar 17 har gjorts i samband med profileringen. Perforeringarna är täckta av ett material 20 som täcker hela underflänsama. Detta material 20 ska hindra betongen att rinna ut genom perforeringarna vid gjutningen. Det ska också tillåta överskottsvatten att rinna ut genom perforeringama. När betongen härdat ska materialet 20 dessutom ta upp fukt ur betongen och självt torka genom slitsarna 17 för att därigenom medge att betongen torkar nedåt. Genom att materialet 20 har så stor yta mot betongen och fördelar fukten både i sitt plan och tvärs planet påskyndas betongens torkning. Även om man lägger ett diffusionstätt övergolv på betongen kan således betongen torka ut. Man kan montera ett undertak utan att torkningen störs eftersom ett undertak inte är diffusionstätt. Totalt sett kan byggnationen färdigställas mycket snabbare än vid användning av konventionell tät plåtform och dessutom utan risk för mögelbildning. 31 1: Illlz; 510 519 The ends 12 are perforated by making rows of short slots 17 in them in connection with the presentation. The perforations are covered with a material 20 which covers the whole the lower flanges. This material 20 should prevent the concrete from flowing through the perforations during casting. It should also allow excess water to drain out through the perforations. When the concrete has hardened, the material 20 must also absorb moisture the concrete and dry itself through the slots 17 to thereby allow the concrete dries downwards. Because the material 20 has such a large surface against the concrete and distributes the moisture both in its plane and across the plane, the drying of the concrete is accelerated. Even if you add one diffusion-tight upper floor of the concrete, the concrete can thus dry out. You can mount a suspended ceiling without disturbing the drying because a suspended ceiling is not diffusion-tight. In total seen, construction can be completed much faster than using conventional dense sheet metal form and also without risk of mold formation.

Materialet 20 ska vara ett material med hög permeabilitet för fukt både i sitt eget plan och tvärs sitt plan. Det kan utgöras av en sk geotextil, dvs en duk eller filt som vanligen används i marken som barriär mellan lera och ett dränerande material. Man kan också använda mineralullsskivor som då kan vara exempelvis 10 mm tjocka. I båda fallen kan materialet läggas löst i underflänsarna vid formsättningen eller limmas fast på underflänsarna i samband med tillverkningen av formelemcnten. Man kan också spruta på en porös massa som torkar och får lämpliga egenskaper. Även andra material än de här nämnda kan användas om de har lämpliga egenskaper.The material 20 should be a material with high permeability to moisture both in its own plane and across its plane. It can consist of a so-called geotextile, ie a cloth or fi lt as usual used in the soil as a barrier between clay and a draining material. One may also use mineral wool boards which can then be, for example, 10 mm thick. In both cases can the material is laid loosely in the lower flanges during molding or glued on the lower flanges in connection with the manufacture of the formula element. You can also spray on a porous mass that dries and acquires suitable properties. Even materials other than those mentioned here can be used if they have suitable properties.
