Definitions

  • the present invention relates to a composite foam-glass element and, in particular, to a composite foam-glass-panel element having at least one, preferably a plurality of foam-glass bodies or foam-glass panels, as well as to constructions produced therefrom and methods for producing the same and the application thereof.
  • Foam-glass panels are already known from the state of the art and are mainly used as thermal insulation material. Due to the structure of foam-glass from a plurality of pores surrounded by a glass matrix, foam-glass has excellent properties, in particular thermal insulation properties. Foam-glass has a high compressive strength relative to its weight, is chemically resistant, can be configured to be water- or vapour-tight when the porosity is closed, is non-flammable and pest-proof, has low thermal conductivity and is extremely durable. Meanwhile, foam-glass panels can also be produced ecologically and sustainably, economically 100% from recycled glass. Panel sizes of 3 m ⁇ 1.5 m can already be produced on an industrial scale.
  • foam-glass has a relatively low tensile strength.
  • foam-glass is relatively brittle. As a result, the areas of application or use are limited.
  • foam-glass panels i.e. foam-glass bodies with a defined shape and dimensions, which enable a defined arrangement of individual foam-glass bodies, is very complex, since very slow cooling must take place to avoid residual stress cracks during cooling. Accordingly, foam-glass is also often used as foam-glass ballast with a plurality of foam-glass grains of undefined shape, which is easier to produce for the appropriate reasons and can also be used as a thermal insulation material.
  • foam-glass panels Due to the complex production and the brittle behaviour with low fracture toughness of foam-glass panels, the use of foam-glass panels is still limited despite the outstanding properties with regard to thermal insulation properties, non-flammability, compressive strength and low specific weight.
  • a composite foam-glass element and in particular a composite foam-glass panel element having at least one, preferably a plurality of foam-glass bodies and at least one reinforcing element is proposed, wherein the at least one reinforcing element is arranged such that the at least one reinforcing element applies a compressive stress to the one or more foam-glass bodies at least along one direction.
  • the composite foam-glass element can be used under tensile loads and, in particular, also under bending loads.
  • the composite foam-glass element can replace conventional building materials such as concrete or wood due to its improved mechanical properties compared to simple foam-glass panels. In view of the fact that cement production has a high energy requirement and releases considerable amounts of CO 2 (approx.
  • the composite foam-glass element according to the invention is very advantageous in terms of energy consumption and CO 2 emissions compared to conventional building materials because, during production, the glass material is not completely melted, but heated to only approx. 800° C. in the presence of additives.
  • Foam-glass is also an excellent insulating material and in addition it is not flammable and can be protected from weathering by cladding. It is also significantly lighter than conventional building materials and can therefore be transported and installed with less energy input.
  • reinforcing elements/tensile elements that run through the foam-glass bodies forming a composite foam-glass element are better protected against thermal material fatigue in the event of a fire.
  • the invention offers a forward-looking building material for numerous applications, because the composite foam-glass element according to the invention combines the low energy consumption, low CO 2 generation, thermal insulation, fire resistance and reusability of foam-glass with the mechanical stability (compressive, tensile and flexural strength) required for the construction of buildings.
  • Foam-glass bodies received in the composite foam-glass element according to the invention can be understood as bodies that are integrally formed from foam-glass and/or have a homogeneous structure, wherein a plurality of enclosed pores are surrounded by a glass matrix. These may be open or closed pores, wherein, when the pores are closed, no fluid such as water, for example, can permeate into the pores from the outside.
  • the foam-glass bodies of a composite foam-glass element may be configured with varying properties of the foam-glass bodies.
  • the density of the foam-glass bodies may vary such that higher density foam-glass bodies are used in certain areas of the composite foam-glass element, while lower density foam-glass bodies may be used in other areas.
  • the moduli of elasticity of the foam-glass bodies can also be different and adapted to the intended use.
  • different foam-glass bodies can also be used in a composite foam-glass element, which differ in other properties, for example with regard to an open or closed porosity.
  • a composite foam-glass element only the same foam-glass bodies or foam-glass bodies with different properties can be used.
  • the foam-glass bodies of a composite foam-glass element can all be configured identically in shape and/or size, but different foam-glass bodies, which differ from one another in shape and/or size, can also be received in a composite foam-glass element.
  • the foam-glass body may have a defined shape and dimensions that allow the corresponding foam-glass bodies to be arranged in a defined manner in the composite foam-glass element.
  • the dimensions can be selected such that composite foam-glass elements can be formed, which are suitable for the design and constructive use for the production of constructions or parts of constructions and in particular of buildings or parts of buildings.
  • the minimum dimensions of a foam-glass body or a composite foam-glass element may be in the range of 1 cm, 5 cm or 10 cm and more, while the maximum dimensions of a foam-glass body or composite foam-glass element may be in the range of some 10 cm, for example 50 cm, 1 m, 2 m, 5 m, 10 m or more.
  • the minimum dimension or minimal dimension of a foam-glass body or a composite foam-glass element represents the dimension of the foam-glass body or the composite foam-glass element that has the smallest extent and can be present, for example, in the thickness or width direction, while the maximum dimension of a foam-glass body or composite foam-glass element is the dimension of the foam-glass body or the composite foam-glass element that has the largest extent and can accordingly define the longitudinal direction.

Accordingly, opposing surfaces of a foam-glass body may be configured complementary to one another, or the contact surface of a foam-glass body may be adapted to the contact surface of another, differently configured foam-glass body. Correspondingly, other foam-glass bodies can then be arranged on the at least one contact surface.
  • the foam-glass bodies can be arranged in rows and/or columns on top of one another and/or one behind the other and/or next to one another in order to form different shapes of composite foam-glass elements.
  • the surfaces of the foam-glass body can be configured as contact surfaces, which represent the largest surfaces, in order to maximise the mutual frictional force of the contacting foam-glass bodies.
  • a foam-glass body may have a first contact surface on one side and a second contact surface that is configured to be complementary to the first contact surface on an opposite side, so that a plurality of these foam-glass bodies can be arranged in a bond or stack.
  • the contact surfaces may have projections and/or depressions. If the contact surface is defined by a plane spanned in a Cartesian coordinate system in the x- and y-directions, the projections and/or depressions extend in the z-direction running perpendicular to the xy-plane.
  • the projections and/or depressions can periodically repeat in one or both directions of the xy-plane, i.e. in the x- or y-direction, so that the contact surfaces may have a undulating or sawtooth or nub-like surface shape.
  • the foam-glass bodies in a composite foam-glass element can be stacked one on top of the other and/or one behind the other and/or next to one another and/or arranged in the manner of a brickwork, without binders such as are provided, for example, with mortar in brickworks, being placed between the foam-glass bodies.
  • the foam-glass bodies in the composite foam-glass element may at least partially have no cohesive connection with one another, but preferably no cohesive connection at all, so that a corresponding composite foam-glass element can also be recycled again in a simple manner, since foam-glass bodies and reinforcing elements and their components can easily be separated from one another again.
  • the type of arrangement of the foam-glass bodies in a composite foam-glass element can take place in different ways.
  • known types of brickworks may be formed, such as load-bearing bond, stretcher bond, header bond, English bond, cross bond, or the like.
  • simple stacks in which the foam-glass bodies are provided in a single-layer or multilayer stack of individual foam-glass bodies arranged on top of one another or in rows are possible.
  • the foam-glass bodies may be arranged in a stack, aligned from row to row, on top of one another and/or staggered relative to one another.
  • the foam-glass bodies can at least partially directly and/or directly contact one another in the composite foam-glass element, or at least partially separating elements, for example in the form of sheets or films, can be provided at least partially between adjacent foam-glass bodies.
  • the sheets or foils may be formed from paper, cardboard, rubber or plastic, for example polyisobutylene, textiles such as woven fabrics, crocheted fabrics, knitted fabrics, braided fabrics, sewn fabrics, nonwovens and felts or other suitable materials.
  • the separating elements can be configured in such a way that they are elastically or plastically deformable, so that they can penetrate into the rough surface of the foam-glass bodies and, on the one hand, prevent mutually abutting foam-glass bodies from damaging one another and, on the other hand, cause the frictional force between the foam-glass bodies to be increased, in order to strengthen the cohesion of the foam-glass bodies in the composite foam-glass element and thus the strength of the composite foam-glass element.
