Description

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. As 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.

The development showed that in steel construction glass panes that have a space-closing function, also as a reinforcement of the Main supporting structure can be used. Here is the Disc is stressed in its plane (disc load-bearing effect).

The connections used are 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.

Only the pure constructive glass construction represents fully load-bearing Glass components. Here are all that occur in a building Loads transferred over glass components. As connections become adhesive bonds and connections with several Bolt (similar to a dowel joint in the load-bearing capacity used in timber construction). Both types of connection are to be regarded as stiff, but organic glue in general are susceptible to aging. A serious disadvantage of pure glass constructions is the brittleness of the whole System. The remaining stability (load capacity after breaking a sheet of glass) of such constructions is rather low and is an uncertainty factor.

In summary, it can be said that conventional Connections that are sufficiently rigid (point holder), due to the concentration of stress only small loads can transmit, and vice versa connections that do not Cause stress concentrations, are very compliant (soft intermediate layers). The stiff glass-glass adhesive connections bring the disadvantages depending on the adhesive used aging and weathering by water or UV light.

Based on this known prior art, 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.

To solve these tasks is a procedure of the beginning mentioned type essentially characterized in that at least one edge or an edge of the glass element in the curing material is introduced before curing and that the edge or the edge of the glass element after curing of the hardening material of this essentially positively surrounded or enclosed and clamped becomes. The fact that according to the invention an edge or an edge of the glass element from the hardening material essentially is positively surrounded or enclosed and clamped, can voltage peaks due to the continuous or linear Connection or load transfer between the Glass element and the body made of a hardening material, especially concrete can be avoided. This is no more the connection between the glass element and the hardening Material determining the load-bearing capacity of the pane and it can completely support the load-bearing capacity of the glass element be used.

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.

Glass cannot be made so perfectly flat that direct contact with another hard and rigid structure (e.g. steel) even stress distribution under load arises. Because of the bumps Glass have point contact in several places, causing there with known connections very high voltages occur that lead to early breakage of the glass.

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.

To stresses occurring between the glass element and the body made of hardening material, especially concrete, to achieve a full load capacity of the connection to the 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. In this context, according to a preferred embodiment suggested that the glass element at least in Area of the edge or edge for connection to the hardening material before introduction into the hardening Material is cleaned to ensure proper adhesion of the hardening material, if necessary impurities located on the surface of the glass difficult.

To improve the adhesion between the hardening Material and the glass element is on a good toothing targeted between the glass element and the hardening material, in this context according to another preferred embodiment it is proposed that the Glass element in the area of the connection with the curing Material before it is introduced into the hardening material a surface treatment with organic or inorganic Substances, for example sandblasting or etching, is subjected. 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.

Other options, a gear or mutual Connection between the glass element and the curing All types of material are gross Change in shape of the glass element in the area of the connection, in this context according to another preferred Embodiment is proposed that the glass element in the area of the connection with the hardening material the introduction into the curing material of 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.

In addition to such a surface treatment of the glass element in the area of the connection with the hardening material can, as already indicated above, in addition or alternatively according to a further preferred embodiment be provided that 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. According to a particularly preferred embodiment it is proposed that the coating be coated by a Enamel or an adhesive, especially with a high modulus of elasticity and / or high adhesive tensile strength.

To further support the connection between the Glass element and the hardening material is beyond suggested that a granular material, for example sand, and / or reinforcement, for example a glass fiber mat, introduced or recorded as a further preferred embodiment corresponds to the method according to the invention. Such 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. If 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.

To improve the mutual connection between the Glass element and the hardening material is over it furthermore proposed according to a further preferred embodiment, that a coating of a curing Adhesive after inserting the glass element into the hardening Material hardened together with the hardening material becomes.

To increase the strength and to avoid that during curing the curing material, in particular Concrete, 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. In particular when fibers are added, it becomes possible Limit micro cracking in young concrete while by providing, for example, rod-shaped reinforcements or reinforcements in the immediate vicinity of the glass element a corresponding one in the hardening material or concrete Gain essentially perpendicular to the Disk level is achievable.

In addition to the procedure discussed in detail above, there is a solution a component from the task mentioned at the beginning a blowing element, preferably flat glass element, and one Body made of a hardening material, especially concrete or the like, essentially characterized in that at least an edge or an edge of the glass element essentially positively enclosed in the curing material and is clamped.

Due to the positive or non-positive connection of the glass element with the hardening material is how Already mentioned in detail above, a component or composite element provided, in which the glass element also in particular due to the linear or flat connection a corresponding supporting function can meet.

To achieve a correspondingly secure connection between the glass element and the curing material proposed according to a preferred embodiment that the glass element in the area of the connection with the hardening Material is a roughened, profiled and / or coated Surface.

To further increase the strength or load-bearing capacity of the Component according to the invention is also proposed that reinforcements or reinforcements in the hardening material, for example tension cords, cladding tubes for reinforcements or the like. Are provided.

According to the invention, the use of such a component for the production of non-load bearing or load bearing Composite components or composite components, such as Beams, stairs, railings, partitions, doors, furniture, Furnishings or the like. Proposed.

Beton: Alle zementgebundenen Baustoffe bestehend aus Zuschlagstoff, Zement, Wasser und sonstigen Zusätzen aller Art unabhängig von der Korngröße und der Masseanteile der einzelnen Komponenten.

Glas: Alle Glasprodukte, für die eine Verbindung mit Beton sinnvoll sein kann, wie beispielsweise Produkte aus Floatglas, Einscheibensicherheitsglas, Verbundsicherheitsglas, Gußglas usw., welche aus einer oder mehreren Scheiben bestehen können.

The following description provides a detailed discussion of embodiments in which the hardening material is formed by concrete, wherein instead of concrete similar materials which are used to form construction elements could be used. The following also applies to the general terms concrete and glass:

Concrete: All cement-bound building materials consisting of aggregate, cement, water and other additives of all kinds regardless of the grain size and the mass fraction of the individual components.

Glass: All glass products for which a connection with concrete can be useful, such as products made of float glass, single-pane safety glass, laminated safety glass, cast glass, etc., which can consist of one or more panes.

If untreated glass is used, the rigid Connection bending moments mx, shear forces vz and negative normal forces ny (see Fig. 2) passed from the glass into the concrete become. The intended edge clamping of the glass element increases the resilience of the glass pane under evenly distributed plate load q ideally full clamping by 50% (see Fig. 4). Application examples for this would be facade and roof elements or railings (see Fig. 5).

If the 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).

Due to the possibility of arranging reinforcement 20 or of tendons 23, 24 in the concrete parts 2, 22 of composite components becomes the problem of brittleness and the Residual stability while largely maintaining transparency and aesthetics resolved.

Furthermore, glass can be mechanically toughened by the tendons 20, 23 arranged in the concrete parts 2, 22, 24 be excited. The glass experiences because of the rigid Connection with the concrete parts almost the same upsets like the concrete. This will make the effective tensile strength of the glass increases, which means the resilience is enormously increased until the first crack formation, so that the working load level is raised.

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.

Below are some options for treatment or Surface treatment of the glass element 1, 21, 31 at least in the area of connection with the body or element 2, 22, 30 discussed from curing material. The information from tx, max (see Fig. 2) are test results of a composite push test an 8 mm glass pane that is 2 cm deep a concrete body is embedded. The concrete body is out high-strength concrete (largest grain 2 mm, AR glass fibers, Compressive strength 125 N / mm2):

Conventional sandblasting of the surfaces with corundum 0.5-1 mm [tx, max = 2.0 kN / cm]

Apply an enamel paint mixed with corundum (100 grit) and then firing in the tempering furnace. The means that the thermal tempering of the glass pane and the firing of the enamel color is done in the same process. The Enamel color is usually used for labeling used by toughened safety glass panes. [tx, max = 2.7 kN / cm]

Cover the surfaces with quartz sand (2 mm) with glue with high modulus of elasticity and high adhesive tensile strength, preferably Epoxy resin adhesive [tx, max = 2.9 kN / cm].

Brush the surface with processable underwater Adhesives (preferably epoxy resin adhesive) immediately before wetting with concrete [tx, max = 2.3 kN / cm].

Covering the surface with workable under water Adhesives with high modulus of elasticity and high adhesive tensile strength (preferably epoxy resin adhesive) and 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.

Melting or baking inorganic layers (e.g. Fly ash), which is an additional one when wetted with concrete chemical reaction with the raw materials of the Enter concrete.

Furthermore, there are mixed forms from the above examples possible.

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.

Below are different types of manufacturing the connection between the glass element and the curing Material, especially concrete, discussed in detail.

Glass stationary

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.

Concrete stationary

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 After concreting, 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.

Glass and lower part of the formwork stationary, upper part the formwork slides

For composite components or other glass-concrete bodies with an excellent direction (see e.g. Fig. 3) an extruder or sliding construction process, which itself is based on the manufacturing process of prestressed concrete floorboards, as shown in detail in Fig. 6. The lower Part of the formwork 3 is stationary and can, if possible large length S are executed. To the component dimension to be able to vary perpendicular to the excellent direction 4 and to ease the stripping of the component is recommended it, the lower part of the formwork in two parts perform. This part of the formwork is fixed to one Support part 5 connected, the elastic surface (e.g. rubber) and the support of the glass panes serves. To hold the glass pane firmly in place, For example, the support surface with holes 6 are provided, via which a vacuum 7 on the Bottom of the glass product is applied. The glass products 8 several components (with or without pretreatment, one or multiple discs) must now be in their final length on the support part 5 described above in a row be arranged and with intermediate plates 9 (e.g. from Wood), which is the same thickness as the glass products have to be separated. After attaching the Glass and intermediate plates (e.g. negative pressure) become the necessary ones Reinforcing bars or prestressing strands 10 or cladding tubes positioned by anchoring at the ends 11 (like in hollow plank production).

The upper part of the formwork 12 is on a mobile Concreting car 13, which is on rails along the excellent Direction of the components (x-axis) can. The parts of the upper formwork 12 must be light Pressure laterally against the lower part of the formwork 3 and be pressed against the glass from above. The contact area the formwork to the glass 14 should be made of a (without lubricant) easily sliding material (plastic, wood) that has a significantly lower modulus of elasticity than glass his. Another important part of the pouring car is the front formwork 15, which must be designed so that them from the glass, the tension wires, the cladding tubes or reinforcing bars can be penetrated. The penetrations must be adequately sealed. A concrete hopper 16 is via a concrete line 17 with the formwork room 18 connected. A concrete pump 19 (preferably screw pump due to stiff concrete consistency) be located.

Concreting takes place after loading the wagon with concrete, by pouring the concrete in via the pipe using the pump the formwork space 18 is pressed. As soon as it arises of the concrete body the resistance to the necessary concreting pressure is big enough, the car sits down in motion (positive x-direction) and manufactures on it Way necessary for the connection and the composite components Concrete parts. The length R of the upper formwork, the Fresh concrete consistency, pour pressure and speed of the car must be tuned so that the resulting concrete parts are sufficiently compacted and without upper formwork, taking into account certain tolerances, keep their shape.

After the necessary curing time, the intermediate plates 9 removed, the concrete parts including the tension strands, cladding tubes or reinforcement bars cut in the area of the intermediate plates 9 and the finished composite components from the formwork lifted.
