Definitions

  • the invention relates to a glass structure, particularly a bearing structure having bearing glass construction parts.
  • the invention furthermore relates to an assembly for mutually connecting construction parts in such structures, as well as to connection members for them.
  • glass Due to its properties glass is very alluring to architects and constructors. Up until now use has predominantly been made of the transparency and/or translucency of glass and glass mainly has a partitioning function, particularly a climate partitioning function. Glass panels are thus used in casings, doors and/or as facade cladding or in glass facades. In said uses the glass panels are connected to a bearing structure of for instance wood, metal, stone or concrete.
  • the glass structure according to the invention comprises a first and a second glass construction part, each provided with at least one main surface, particularly bearing glass panels, wherein both construction parts are interconnected by means of at least one connection assembly so as to transfer forces, the connection assembly comprising:
  • the bearing glass construction parts can be used for transferring constructive forces, despite it being glass (panels).
  • the structure according to the invention may thus have the function of a girder, particularly in a (foot) bridge. Separate girder parts, such as steel tube structures, for the bearing function may at least be partially dispensed with.
  • the glass construction parts are panel-shaped and they are situated in a plane that is approximately or entirely vertically oriented.
  • connection surface is provided with a recessed edge area, such as a slot running along its circumference.
  • the superfluous glue may flow in said slot.
  • the bounding edge of the slot facing away from the first connection surface preferably is recessed, so that it is spaced apart from said main surface of the glass construction part. This ensures that only the connection surface contacts the glass construction part, and thus prevents that other parts of the connection member than the connection surface support on the glass construction part.
  • each connection member comprises a bonding disk provided with the connection surface.
  • the bonding disk is provided with coupling members for coupling the third connection member thereto.
  • the third connection member is adapted for transferring normal forces, tensile forces and/or pressure forces.
  • connection member is connected with the bonding disk so as to hinge about a centre line that is substantially perpendicular to the main surface.
  • the third connection member is moment-fixedly connected to the bonding disk, considered in a plane perpendicular to the main surface.
  • each of the first and second connection members comprises a second connection surface, wherein the first and second connection surface are placed opposite each other and on the said main surface of the said glass construction part.
  • the two connection surfaces that are attached to either side of the glass construction part by means of an adhesive may be loaded mirror-symmetrically with respect to the centre plane of the glass construction part, which results in an advantageous transfer of forces.
  • first and second connection surface preferably are substantially congruent, which enhances a proper transfer of forces and also enhances the look.
  • identical first and second connection surfaces are preferred for production-technical reasons; for a device according to the invention namely only one type of connection surface needs to be designed and produced.
  • each of the connection member comprises a first bonding disk provided with the first connection surface, and a second bonding disk provided with the second connection surface and a coupling member extending through the through-opening for mutually coupling the first and second bonding disk.
  • the first and second bonding disk are substantially congruent.
  • the coupling member comprises biassing means for exerting a clamping force oriented towards each other on the first and second bonding disks.
  • the biassing means ensure a little pre-biassing on the connection in order to increase operative portion of the connection surfaces. In this way the effects of peeling-tensions, generated by for instance internal moments, wherein there is question of forces that are transverse to the main surface and moments that tend to move the connection surface and the construction part away from each other, are counteracted.
  • the first and second bonding disk comprise a through-opening through which the biassing means have been passed, wherein the biassing means preferably abut a side of the first and second bonding disk that faces away from the glass plate, and wherein the biassing means preferably comprise a nut and an axle, wherein the axle is provided with an external thread near at least one of its ends, wherein the nut can be screwed onto the end of the axle provided with the external thread for adjusting the clamping force on the first and second bonding disk.
  • first and/or second connection surface is placed near the through-opening in the main surface of the glass construction part and spaced apart from an edge of said through-opening.
  • the weakened edge area of the through-opening is thus kept free from contact, spanned by the said bonding disk, and is not loaded.
  • the bonding disks can be made from one piece of metal or a metal alloy or a synthetic material.
  • a durable and low-maintenance material such as for instance stainless steel
  • the relatively little difference between the coefficient of thermal expansion of stainless steel and that of glass prevents problems due to temperature differences.
  • the machinability is good which is important as the bonding disks are made on a lathe.
  • the visual combination of glass and stainless steel can be considered attractive.
  • the third connection members comprise bars transferring normal forces, coupling strips or coupling rods that directly or indirectly engage onto the coupling member, particularly the axle, and which preferably are also made of a metal or a metal alloy or a synthetic material.
  • one or more third connection members are placed at a side of each bonding disk that faces away from the glass construction part. In this way a moment-fixed connection can be realised for buffering the different forces and moments that are active on the glass structure according to the invention.
  • connection members As regards the transfer of forces it is advantageous in this case if on either side of the main surfaces of the first and second bearing glass construction parts third connection members have been placed, and particularly when the third connection members are placed substantially parallel and mirror symmetrical with respect to the main surfaces of the first and second bearing glass construction parts.
  • the coupling member will as a result usually be loaded by forces that are oriented substantially parallel to the connection surfaces. Said forces of the coupling member are transferred onto the bonding disks. It is advantageous here when the dimensions of the axle and the through-openings in the bonding disks have been selected such that the axle can be fittingly placed in said through-openings. In other words, the circumferential surface of the axle abuts the internal surface of the through opening, for transferring the forces.
  • connection surfaces have a rotation-symmetrical shape.
  • bonding disks also have a rotation-symmetrical shape.
  • connection surfaces can be loaded in any direction and the manufacturing and mounting is relatively simple.
  • the thickness of the connection formed by the adhesive is smaller than 1 mm, preferably smaller than 0.2 mm. Little deformation can occur in the thin layer of glue, so that a highly rigid and creep-proof connection is realised.
  • connection member or a glass construction part for a glass structure as described above.
  • the invention provides an assembly for interconnecting glass construction parts provided with at least one main surface, particularly bearing glass panels, comprising
  • the invention provides a glass construction part comprising two opposite main surfaces, a through-opening extending substantially perpendicular to the opposite main surfaces, and an assembly as described above, wherein the first and second connection surface near the through-opening and spaced apart from an edge of said through-opening are attached to the opposite main surfaces of the glass construction part by means of an adhesive, and wherein the coupling member extends through the substantially aligned through-opening in the glass construction part and the first and second through-openings.
  • connection members such as the connection members, bonding disks, coupling members, composed connection members and glass construction parts, and other aspects may the subject of divisional patent applications related thereto.
  • glass construction parts can be interconnected as shown for instance in figure 1. It is noted that with the bearing structure of bearing glass plates that are connected to each other so as to transfer forces, girder structures and column structures and other bearing structures can be made, such as an overhanging girder, a bearing column, etcetera.
  • the glass plates are situated in a vertical plane, or at a small angle thereto, so that the glass is able to transfer forces in its plane.
  • Figure 1 schematically shows a design of a glass bridge 1 having a large span S wherein the bearing structure is formed by (in this example) seven glass construction parts, such as for instance glass panels 2.
  • the drawing only shows one vertical or upright longitudinal wall 1 a. It will be understood that behind the longitudinal wall 1 a shown a second longitudinal wall, spaced apart therefrom, will be present.
  • connection assemblies comprising first and second connection members 3, which devices 3 are connected to the glass construction parts 2 by means of a glue connection as described below.
  • the first and second connection members 3 are mutually coupled by means of third connection members 4 which in the shape of strips or rods preferably made of steel and at the ends are hingingly attached (in a plane parallel to glass plate 2, direction A) on the connection members, so that they form rods with hinge ends.
  • a moment-fixed connection can be realised by placing first and second connection members 3 at the upper and lower side of both glass plates 2 to be coupled and interconnect them by means of steel strips 41. Transverse forces can be absorbed by means of a diagonal rod 42.
  • a span built up from bearing glass plates can be realised that is able to reliably bridge the distance S between the points of support 5.
  • the longitudinal walls 1 a here as it were form a girder or beam.
  • FIG. 2 shows a connection assembly between two glass construction parts 2 in more detail.
  • Each of the first and second connection members 3 in this exemplary embodiment comprises a round and disk-shaped bonding disk 31 which by means of a glue connection is connected to the glass construction parts 2.
  • a bonding disk 32 is glued, wherein the opposite bonding disks 31, 32 are mutually coupled by means of a coupling member 33 as schematically shown in the cross-sectional view of figure 3.
  • the first exemplary embodiment of the device for interconnecting glass construction parts as shown in figure 3 comprises a first bonding disk 31 and an identical second bonding disk 32 that are glued substantially opposite each other onto a glass plate 2.
  • Both bonding disks 31, 32 are each provided with a connection surface 311, 321 forming an annular glue surface that remains placed at a distance around a through-hole 21 in the glass plate 2 and thus leaves the edge area of the glass around the hole free.
  • the bonding disks 31, 32 are round stainless steel disks having a diameter of approximately 120 mm and a thickness of approximately 15 mm. In the centre there is a through-hole 312, 322 for passing a coupling member 33 through.
  • the annular connection surface 311, 321 is situated between two circles of approximately 50 and 104 mm in cross-section.
  • flow-out ducts 313, 314, 323, 324 for the glue have been disposed around the connection surface 311, 321.
  • said flow-out ducts 313, 314, 323, 324 are formed as a recess having a radius of approximately 2 mm.
  • connection surface 311, 321 and the flow-out ducts 313, 314, 323, 324 has a radius of approximately 1 mm. This detail ensures a lower tension in the outer edge of the glue layer.
  • the part of the bonding disks 31, 32 that sits within the innermost flow-out duct 313, 323 is elevated approximately 1 mm, thus sits 1 mm above the glass plate 2 and thus is not glued together on the glass plate 2. Due to the high rigidity of the stainless steel disks 31, 32 with respect to the glass 2 (approximately factor 5) said centre section will almost not be loaded and deform.
  • the outermost edge area of the bonding disk 31, 32 beyond the outermost flow-out duct 314, 324 is approximately 1 mm above the glass plate 2 in order not to let glue run out from underneath the disk and to be able to monitor the flow-out of the glue in the outermost flow-out duct 314, 324.
  • the bonding disks 31, 32 preferably are glued together on the glass 2 using a two-component epoxy by a glue layer that is 0.1 to 0.2 mm thick. Such a thin glue layer results in a glue connection having a large strength and rigidity.
  • the device as shown in figure 3 further comprises a coupling member 33 that interconnects the bonding disks 31, 32.
  • Said coupling member 33 comprises a threaded end 331.
  • the threaded end 331 can be placed fittingly in the bonding disks 31, 32 without contacting the glass 2, where the hole is wider than the diameter of the axle 331.
  • the threaded end 331 is provided with two nuts 332 which after the glue has fully set need to be tightened for further pre-biassing the bonding disks 31, 32 against the glass.
  • the bonding disks 31, 32 Due to this pre-biassing which presses the bonding disks 31, 32 towards each other, peaks in the peeling-tensions may at least be largely compensated.
  • the bonding disks 31, 32 have an annular glue surface that goes widely around the hole 21 in the glass plate 2 so that the weak edges of the hole 21 in the glass 2 are not glued and therefore are not loaded either.
  • the hole 21 in the glass 2 is broad enough to compensate the tolerances in the placement of the hole 21 and to make some bending and scoring of the threaded end 331 possible.
  • connection member as shown in figure 3 can be coupled with a further identical second connection member on another glass plate by means of a third connection member in the form of steel tension members, strips or rods that are coupled on both sides of the glass plate 2 with the coupling member 33.
  • connection surface 311, 321 results in an efficient tension distribution, wherein small connection surfaces (smaller than 25 mm) have a higher efficiency because, as the length of the overlap becomes larger the centre section contributes less to the tension transfer. Two separate small connection surfaces behind each other therefore result in a larger strength than one large connection surface does.
  • the bonding disks 31, 32 are preferably glued onto the thick centre glass plate 2 as shown in figure 4.
  • a hole is made that fits freely around the bonding disks 31, 32.
  • the bonding disks 31, 32 are provided with a circumferential edge 315, 325 which substantially extends over the layers 22, 23 so that no border of the hole is visible in the layers 22, 23 around the bonding disks 31, 32.
  • the intermediate layers 221, 231 will have to be removed.
  • the bonding disks 31, 32 can be connected with the third connection members 4 by means of coupling members as is also shown in figure 5 to be discussed below.
  • Figure 5 shows a further exemplary embodiment wherein two glass plates 2a, 2b are placed parallel and wherein two connection members are placed in series and share a common coupling member in the form of a threaded end 331.
  • the first glass plate 2a and the second glass plate 2b are both provided with a through-hole around which the laminated layers 22a, 23a, 22b, 23b have been removed. Bonding disks 31 a, 32a, 31 b, 32b have subsequently been connected with the two glass plates 2a, 2b by means of their bonding surfaces.
  • the filler piece 412 may also serve for connecting one or more third connection members 41 thereto, such as for instance a coupling rod, for coupling the two glass plates 2a, 2b placed parallel to further glass plates of a glass structure according to the invention.
  • third connection members 41 such as for instance a coupling rod
  • end bushes or end caps 411 have also been placed for covering the ends of the threaded end 331 and the nuts 332.
  • Said end caps 411 can also be adapted for connection thereto of one or more third connection members 41. It is advantageous here for the force distribution if the exemplary embodiment as shown in figure 5 is mirror-symmetrical with respect to the plane that is parallel to the glass plates 2a, 2b and is situated in the middle between said glass plates 2a, 2b.
  • the end bushes 411 and the bush 412 are rotatable about centre line X, in directions A, in a plane parallel to the main surfaces.
  • the bushes 411 and 412 can be rotatable about inner bushes 413 and 414, which themselves may be rotation-fixed with the axle 331 and the bonding disks. In a direction perpendicular to the main surfaces, however, the connection of the rod 41 with the bonding disk 31 a, 31 b, 32a, 32b is moment-fixed.
  • connection assembly 3, 41 shows that the connection assembly 3, 41 according to the invention, after some adjustments can also be used for interconnecting two glass plates 2, 6 that are perpendicular to each other.
  • the coupling member of the first and second connection member 3 of the glass plates 2 is lengthened 43 in the direction of the coupling member 33 of a first connection member 31 of the glass plate 6, and connected thereto.
  • a tensile force in the plane of the glass plate 6 butt loads the first connection member 31 of the glass plate 6, whereas here the first and second connection members 3 of the glass plates 2 are loaded by means of an axial pressure (perpendicular to the plane of the glass panels 2).
  • the forces are transferred by means of substantially shearing stresses in the first connection member 31 of the glass plate 6 only.
  • first connection member or assembly according to the invention may instead of or in addition to a connection with a second connection member or further assembly, be connected to the points of support or a bearing structure for the glass structure, for transferring constructive forces from the glass structure to the points of support or bearing structure.
