Definitions

• the invention relates to the panel with built-in cellular structure, which is suitable in particular for construction of insulation layers in building industry.
• the panel can be used in particular for base, floors and facing of buildings.
• Construction panels and insulation panels are currently available on the market. Predominantly classic construction elements such as bricks, blocks and wood are still used for the very buildings. Construction panels that are used for construction are usually from materials based on cement, such as concrete, cellular concrete etc. It is usually necessary or suitable to face buildings from these materials or their parts with insulating panels or the panels from insulating materials are eventually built-in directly into floor, base, terrace, etc. Insulating panels are thus used as an interlayer or as a surface facing. Broad choice of hitherto insulating panels is available on the market, but generally each type of these panels shows significant disadvantages.
• foils from plastics are used for waterproofing. These foils have simple structure of a sheet of material, usually supplied in rolls. Advantage of a foil is that it is flexible and provides also certain degree of sound and heat insulation, but the level of sound and heat insulation reached is very poor.
• polystyrene boards For instance boards from polystyrene or rock wool are used for sound and heat insulations.
• Advantage of polystyrene boards is their low mass and no water absorption capacity, but their significant disadvantage is their low mechanical resistance. They are fragile and they can fracture on impact, stress, or when a heavier object is leaning against these boards. Polystyrene particles can pour out of possible crannies, for instance when used under wood lining.
• Another and fundamental disadvantage of polystyrene is its complete inflexibility so that it is problematic to use it for lining of uneven or dissected surfaces. Polystyrene panels are very often used for insulation layers, however effectiveness of sound and heat insulation is relatively limited.
• so called cellular foil is known in building industry. Its arrangement is described for instance in US pat. 5,449,543 and WO 97/16604. It is created as a system of strips of plastic foil that are interconnected so that a structure of hollow chambers/cells is created between their walls. Cavities of these chambers are open in vertical direction.
• the cellular foil is flexible to great extent. It is delivered in a folded state for manipulation and distribution, where the cellular walls are pressed together, and it is unfolded on a plane at the place of use, by which a honeycomb-like structure with open chambers is created.
• the cellular foil when the cellular foil is in folded state for distribution and storage, its chambers are flat, two- dimensional, and in the unfolded state for its use, its chambers are three- dimensional with through openings.
• This cellular foil is designed to be laid on surfaces of erosion attacked outdoor terrains, such as river banks or slopes along roads, or also backfilling of mining groves, where it is placed to prevent slacking of loosened rock from the walls and unwanted pulverization and fragmentation of surface elements. It is also used for consolidation of bed of constructions such as roads or railways, where it is loosely unfolded on earth base after baring and clearing away of arable soil, or over drainage blanket from gravel and/or sand.
• the cellular foil is then overfilled with gravel and grouted with concrete and, as the case may be, coated with paving asphalt. Sometimes, it is filled directly with concrete.
• Various types of cellular foil are available already, in different types and versions, some of them having cell walls equipped with perforation to allow water permeation and to eliminate unwanted pressures in the building.
• the cellular foil is overfilled with loose materials, while its chambers are filled and covered with setting or non-solidifying loose matter.
• heavy machinery is commonly used on this cellular foil, when it is laid on the place of use and it's overfilling with gravel follows using excavators and subsequently travels by road compaction roller.
• Document CZ U 9885 describes insulation panel consisting of parallel layers, for instance boards from insulation material, which are interconnected by means of grating.
• the parallel layers are at least two and the grating between the layers creates a spacer by means of which a system of hollow chambers is created in the panel. Air, gas, or vacuum is in these chambers.
• the grating is made of metal, plastic, or paper. This panel is strong, inflexible, and water-resistant. It has some, but insufficient, insulation properties. Disclosure of the Invention:
• the invention proposes new panel for use in building industry, with internal cellular structure.
• the new panel is a body containing at least two parallel layers from impermeable water resistant material, from which at least one parallel layer creates the face wall of the panel and at least one layer creates the reverse wall of the panel.
• the essence of the new invention is that at least one flexible cellular foil from plastic is fixed between the parallel layers.
• a building cellular foil is used, i.e. structure created as a system from strips of material spliced together so that these strips spliced together create through chambers with layout similar to a bee comb.
• the cellular foil is fixed in the panel according to the invention in its unfolded state, i.e. in the state in which chambers of this cellular foil are three-dimensional, while parallel layers are attached to the cellular foil from both sides so that they cover openings of chambers. Accordingly, one of these parallel layers is situated on the side of inputs to the cellular foil chambers and the other layer on the side of outputs from chambers.
• the parallel layers as well as cellular foil consist preferably from material based on plastics. This allows easy connection of these materials, gives tensile strength as well as compression strength and also elasticity, preventing tensile as well as pressure cracking, and providing the panel with mechanic resistance.
• the parallel layers are preferably from flexible material. Due to this, possibility of panel bend as needed is reached. Cellular foil from plastic is also flexible, therefore panels in this configuration are able to accommodate their shape to the surface line. This allows using these panels also for uneven surfaces, tiling of corners, projections etc.,- which is significant advantage that other mechanically resistant building materials usually do not have.
• Covering wall can be created on at least one circumferential side of the panel. Due to this, reinforcement and shape applanation is reached.
• the covering wall can be preferably on all circumferential sides of the panel.
• Circumferential frame of the panel is created in this way. Creation of covering wall or walls from flexible material is advantageous because creation of flexible circumferential frame is reached in this way.
• Circumferential frame can be created for instance using elongation and fold of material of the face and/or reverse wall of the panel, or as a set-in frame, but also as a sewn in or ironed band of material, etc.
• the cellular foil chambers can be empty in the panel according to the invention. In this case, cavities of these chambers are filled only with air and are creating here insulating air cavities. Some chambers can be used for reinforcing or fixing elements and in such case, chambers in predominant number will preferably remain empty without filling. Panels created in this way have advantage in that they have low weight, they are flexible, and their shape is easily accommodated to the base. In this case, parallel layers can be loosely laid over chambers or can be fixed to the edges of chambers so that they are firmly closing openings of these chambers on both opposite sides of the cellular foil.
• the chambers of the cellular foil in the panel can be filled with suitable insulating material.
• the contained material is loose, but in such case it is necessary that the parallel layers are fixed to the edges of chambers so that they are firmly closing openings of these chambers oh both opposite sides of the cellular foil.
• Filling of chambers can be homogeneous or heterogeneous, of the size ranging from dust particles up to larger particles, for instance also according to the height of the cellular foil used. It can be for instance from 2 cm to 30 cm high, and also a cellular foil with larger or smaller chamber diameter can be selected, especially depending on the intended panel size and purpose.
• the loose filling of chambers is preferably created by particles predominantly in the size range from dust particles up to the diameter of 6.5 cm.
• the filling of chambers is preferably created at least partially by particles of loose material with heat insulating properties, for instance particles based on glass and/or polystyrene.
• the filling of chambers is preferably created at least partially by particles based on foam glass and/or waste glass cullet and/or glass powder.
• This filling is environment friendly and it has many advantages. Panel with this filling does not absorb water, it is permeable to air, and it has relatively low weight. It has excellent heat and sound insulation properties. It can be easily disposed of without environmental burden. It also allows reutilisation of wastes based on glass. This filling is easily stored and it is suitable for use from the health point of view. It also allows easy production of panels because when using this filling, it is possible to fix parallel layers to the cellular foil simply by cementing or ironing using heat.
• the invention expects production of new panels especially in the waterproofing form, i.e. without openings.
• the walls of chambers of the cellular foil, and as the case may be also at least one parallel layer, are perforated. Ventilation holes then allow for high degree of steam permeability and ventilation.
• the invented panel is utilisable in building industry both for laying as well as for lining and facing. It can be used for instance for insulation of floor constructions, as roof insulation, and/or as interior or exterior lining of buildings and other constructions. It can have a surfacing allowing its use without further lining, or it can serve as a layer that will be furnished with another, for instance solid lining. It can serve as humidity insulation, heat insulation, and sound insulation. It allows use also for uneven surfaces.
• the panel can be produced in a flexible form that can be turned and modelled. It is therefore possible to use it even for complicated floor structures and undulating walls and for sharp angle bends. These panels can be custom made with various dimensions and height. During manufacture, waste secondary raw materials such as construction and waste glass etc. can be reutilised.
• the panel is not pulverizing, cracking, warping after contact with water, and compared to other panels, for instance concrete or plasterboard, it has low weight.
• Production of the invented panel is relatively undemanding regarding materials, manipulation, staff as well as qualification, and the panel thus allows availability for producer as well as consumer with low purchase costs.
• Cellular foil of suitable selectable height preferably from 2 cm to 30 cm, can be used in the panel, with smaller or larger chambers considering the required panel elasticity, chamber filling used, spatial and other conditions at the place of panel application etc.
