Abstract

Cement panel, capable of being employed in civil and building constructions, in particular to form boxes, shelves, moving walls, intermediate floors and the like, characterized in that it comprises an aerated concrete core (1), and a surface finish (2, 3) on both sides, reinforced with a traction-resistant material (4), the arrangement being such as to give the panel lightness, mechanical strength, a high level of thermal and acoustic insulation, high resistance to damp and excellent fireproofing qualities.

Description

CEMENT PANEL DESCRIPTION The present invention relates to a cement panel suitable for use in building constructions and the like, in particular to form boxes, shelves, moving walls, intermediate floors and the like.
As is known from the state of the art, solutions already exist for uses of this kind. For insulation against sound and atmospheric agents it is possible to Use panels with an extruded polystyrene core, which makes the panels light and gives good insulation against damp and sound. This core is coated on both sides by a layer of resin-based mortar or the like, reinforced with fiberglass netting to give said panel greater resistance to mechanical stress and wear due to atmospheric agents and sunlight. Said panels are used to cover roofs and walls or as insulation for rooms. However, such kind of panels give a problem in that they are not fireproof, as their core is in polystyrene and this material has an extremely low resistance to high temperatures. Furthermore, extruded polystyrene is a material with extremely low mechanical strength, which limits the use of these panels to certain coating applications only. As an alternative to these panels, there exist panels constructed in the same manner, but with a core in pressure stabilized aerated concrete covered on both sides by a layer of cement mortar reinforced with a fiberglass net, which gives them greater resistance to mechanical stress and aging, and particularly impermeable to water. While these panels keep the lightness characteristic of aerated concrete, they have greater mechanical strength with respect to those mentioned above in extruded polystyrene, as is typical of concrete elements, give a good level of thermal and acoustic insulation and excellent behaviour in face of fire, being practically flame-resistant. These panels are therefore used to cover roofs, to protect areas against atmospheric agents, as fire barriers, internal walls and the like.
The problem with these panels is that they require extremely laborious manufacturing techniques carried out in large industrial plants, which involve much higher costs than the panels described initially.
The object of the present invention is to provide a panel that is light and extremely strong mechanically, that gives excellent thermal and acoustic insulation, that is extremely resistant to damp and has excellent fire prevention characteristics.
A further object of the invention is to provide a panel that can be used as a tile and can be applied to any surface with ease.
The panel according to the present invention comprises a core in aerated concrete and a surface finish on both sides in cement mortar reinforced with a fiberglass net, giving the panel a high resistance to mechanical stress.
The present invention will be more clearly illustrated in the following with reference to a preferred embodiment thereof, given as a non-limiting example, with reference to the sole figure enclosed, which shows a perspective view of the panel.
With reference to the figure, the panel according to the present invention comprises a aerated concrete core 1, finished on both sides with a layer of cement mortar, indicated with numerals 2 and 3, respectively, said layer being reinforced by a net (dotted line 4) of traction-resistant material, for example fiberglass, providing said panel an improved resistance to mechanical stress.
This arrangement makes the panel extremely light, very resistant to shock and aging, provides a high level of thermal and acoustic insulation, high resistance to damp and water (it does not warp and is frostproof) , and also high resistance to fire.
Furthermore, the presence of said layer of mortar makes the panel capable of being used as a tile, fixed with normal tile adhesives, and also makes the panel easy to apply on any surface, either using adhesive (for example mortar or bitumen adhesives) or using nails, screws and pins.
The aerated concrete in the panel according to the present invention has, preferably, a specific weight of 0.3 to 0.8 kg/dm3.
The main uses for the panel, which can also be made-to-measure, are the following: formation of look-out posts, bins, covering panels; closure of passages through walls, floors, etc,; formation of shower surrounds, kitchen surrounds, base units, shelves; mobile walls, interlinings, dividing walls, intermediate floors; interspaces under damp floors (cellars, etc.); floating pavements for D.P.U. ; ceiling-beams to be covered with wood or steel; fireproofing of metal structural elements; for carpentry: panels for doors, fire doors, bins, one-piece windows (outer part) .
The following table gives, purely as an example, several parameters for panels according to the present invention.
