Definitions

  • the present invention relates to a method for producing a component with a connection between a glass element, preferably flat glass element, and a body made of a hardening material, in particular Concrete or the like, on a component made of a glass element, preferably flat glass element, and a body from one hardening material, in particular concrete or the like, and on the use of such a component.
  • Flat glass is not only used as a space-enclosing or decorative, but also used as a load-bearing element.
  • space-closing element e.g. in facade construction
  • the Glass pane only bear its own weight and over wind loads Guide the plate bend to the brackets or glue points.
  • Other loads such as Temperature constraints are caused by Arrangement of connections as soft as possible to the supporting structure avoided.
  • An example of this is EP-A 0 700 776, where a facade element made of concrete is presented on at least one side flatly connected to a glass pane becomes.
  • the disc has mainly a decorative character.
  • the lanyard is a plastic modified Cement mortar that is so elastic that when it is right Choice of layer thickness is capable of different Record temperature expansions.
  • Similar designs an essentially full-area connection between a glass pane and a concrete element are for example also from US Pat. No. 5,763,090 or DE-A 195 43 081 known.
  • connection is clamp connections with soft intermediate layers or point holders. Through soft Intermediate layers, the connection becomes very compliant, which is what is undesirable in the case of bracing. Create point holders very high due to the concentrated load transfer Tensions in the glass, which take full advantage of the load-bearing capacity not allow the disc.
  • the present invention is directed to a method as well as a Component of the type mentioned are available ask, in a simple and reliable manner an im essential non-positive and rigid connection between a glass element and a hardening material, in particular concrete.
  • connection By using the connection, composite components can be made Glass and concrete are produced, which means that the two Materials in the sense of mechanics to a working together Body are fused. With this combination the disadvantages of one material are the advantages the other compensated.
  • the glass panes or elements can be arranged mainly in Slice level (tx, ny, mz) can be claimed. So come their greatest stiffness to effect.
  • the invention solves this voltage peak problem by that the body made of hardening material or Concrete part of the glass in a certain area or along at least one edge wrapped and clamped exactly. It creates a rigid tongue and groove connection that only can be solved by destroying them.
  • the fit is achieved in that the glass pane along of the edge to be connected in direct contact with the curing Material or fresh concrete is brought, so that the edge of the glass pane to be joined along a certain length and to a certain depth of fresh Concrete is encased.
  • the concrete takes the inverse way Shape of the glass.
  • the clamping effect is due to the shrinkage of the hardened material or concrete. Shrinkage is the contraction of concrete due to drying out and by the fact that water and cement are in their initial state have a larger volume than their reaction products, that arise during hydration. This clamping effect the greater the thickness of the used, the greater Glass product.
  • the surface of the glass element must be available at least in the area of the connection, i.e. in the area of Edge or the edge of the glass element are pretreated.

All pretreatments covering the glass surface roughen or thin layers the one with the Glass surface enter a stable bond and on the surface facing away from the glass are rough suitable. Can the applied layers be a chemical Connection with the components of the fresh concrete come in, this can increase the load capacity of the Create connection.

  • a shape-changing Machining such as drilling holes, Cut wavy or sawtooth edges or edges, forming elevations or projections and Recesses or recesses or the like becomes.
  • the glass element in the area of the connection with the hardening material before the introduction into apply a coating to the hardening material becomes.
  • the coating be coated by a Enamel or an adhesive, especially with a high modulus of elasticity and / or high adhesive tensile strength.
  • a granular material for example sand, and / or reinforcement, for example a glass fiber mat
  • a thing granular material, such as sand, and / or a reinforcement formed, for example, by fibers protrudes from the coating, so that an immediate wetting can be achieved with the curing material and the Bond effect between the glass element and the curing Material improved or supported accordingly becomes.
  • materials are introduced into the coating or the coating consists of materials that an additional chemical for wetting with concrete Reaction with the raw materials of the hardening material, especially concrete, can cause another Mutual connection support can be achieved.
  • tensile stress especially in the area of Connection between the glass element and the curing Element evoked is preferred according to another Embodiment suggested that in the curing Material before hardening reinforcements or reinforcements, for example tension cords, cladding tubes for reinforcements and / or reinforcing fibers or the like.
  • tension cords for example tension cords, cladding tubes for reinforcements and / or reinforcing fibers or the like.

  • connection is made with pretreated glass, can all the stresses shown in Fig. 2 from the Connection will be transmitted without being worth mentioning to deform (rigid).
  • glass can be mechanically toughened by the tendons 20, 23 arranged in the concrete parts 2, 22, 24 be excited.
  • FIG. 3 shows an example of a prestressed glass-concrete composite component. If the concrete is used only in small quantities and the concrete part 22 using conventional methods Parts made of other materials combined, so the Concrete 22 works together with the new connection a connecting means for connections of glass 21 with other materials.
  • Adhesives preferably epoxy resin adhesive
  • Adhesives with high modulus of elasticity and high adhesive tensile strength preferably epoxy resin adhesive
  • reinforcement of the adhesive layer with mesh reinforcement (AR glass fiber mat) or textiles which can also protrude into the concrete immediately before wetting with concrete.
  • Pre-treatments without organic adhesives are preferred to use to deal with the problem of aging and of creeping the connection as well as the unfavorable behavior to avoid in case of fire.
  • the glass is thus placed in the formwork and with conventional ones Suction cups or clamped between two woods held in this position or directly between two parts the formwork is clamped in that for the connection certain part of the glass (spring) 1 in the formwork space protrudes and so while filling with hardening material or concrete 2 the function of a counter formwork for the production the groove forms. It doesn't matter which location the formwork body takes up with the glass (lying, standing, Skew).
  • the next step is concreting of the concrete parts that match the position of the formwork body can be done with conventional methods (e.g. Pouring or pumping). If not self-compacting concrete is used, the fresh concrete must be carefully compacted so that there are no nests on the glass surface arise. All conventional methods of compaction are applicable. After the concrete has hardened sufficiently the body can be switched off. The glass part remains in its position and sits firmly in the groove in the concrete.
  • the formwork is made so that that surface of the Concrete body that is planned to be penetrated by the glass pane becomes freely accessible immediately after the concreting process is.
  • Concreting takes place in a conventional way
  • glass is used e.g. with suction cups brought into the planned end position relative to the concrete part (pressed into the concrete) so that the one for the connection intended part of the glass 1 (spring) encased by concrete 2 is (groove).
  • the glass must be in this position for so long are held until, depending on the type of concrete used, sufficient strength of the concrete is present to the Body.
  • the glass part remains in its position and sits firmly in the groove in the concrete.
