Definitions

  • the invention concerns a shear connector adapted for interconnecting at least two structural components, which connector has a number of mandrels and is embedded at least partially, but preferably completely in one of the structural components, wherein the mandrel of the shear connector engages corresponding recesses in the structural components. Furthermore the invention concerns a system of structural components interconnected with each other.
  • a shear connector of this type which is used for producing for example a supporting framework structure, as well as a system of interconnected structural components are known from DE 197 01 458 C1.
  • Frameworks produced in this manner are appropriate for various fields of use. They are used in the construction of buildings as well as in exposition and stage construction or for example in the construction of roller coasters.
  • the system comprised of shear connectors and the cooperating structural components is designed such that the static and dynamic loads affecting the framework can be absorbed.
  • a further aspect of such systems concerns their economic efficiency, which means that they may be produced and assembled in a simple and cost-saving manner. In many cases it is also desirable that the interconnecting system imparts an agreeable aesthetic impression.
  • a typical example of the presently concerned constructions is wooden structural engineering wherein beams or similar supporting components or elements are interconnected to form stable wall, floor and/or roof frameworks.
  • various material combinations are used, i.e. the material wood may be combined with concrete, for example as filling material, but also with plastics or metal components.
  • the material wood solid wood glulams and other wooden materials may be concerned with the solid woods being particularly designed in the form of logwoods, beams, square-shaped timber, shelves and crossbeams, which in relation to the sizes of their cross sections are able to absorb and to transmit relatively high forces.
  • crossbeam a beam is to be understood which is formed by longitudinally partitioning one or several tree trunks and turning the partitioned pieces about their longitudinal axis as well as by subsequently interconnecting these parts to form a new beam, wherein an opening extending essentially centrally along the crossbeam results from the arched faces then lying on the inside and originally forming the outer portions of the tree or trees, respectively.
  • Interconnecting facilities have been developed in manifold manner and introduced in practice, in particular in the region of the ends of these structural elements.
  • some known facilities should be mentioned, for example dowels combined with bolts and additional screw nails, driven-in transversely to the longitudinal axis of the beam in the region of groove and tongue connections, or nail attachments with butt or cover plates, or studs with transversely extending hardwood dowels or embedded T-steel with rod-shaped dowels, or pegs, in particular shearing pegs etc.
  • frontal connections may well also be obtained by a so-called beam joint, wherein the beam sides are provided with support elements for transmitting forces on both sides in the region of their ends by means of transversely extending dowels of particular structure.
  • a wood-construction interconnecting facility for frontal joining of a crossbeam.
  • This includes a shear connector which is embedded in at least one region of an opening extending within the cross beam over its total length in such manner that it is offset backwardly with its outer end with respect to the frontal face of the beam.
  • the shear connector has a rod-shaped core with mandrels sticking out, and an attachment facility on at least one of the core ends.
  • shear connectors of the species concerned for producing an interconnection of several structural components In order to be able to manufacture a plurality of varying nodal points with few parts, only, at the same time aiming at a simple assembling facility, provision is made herein that the shear connector has, apart from the interconnecting option for the first structural component, at least an interconnecting option for a further structural component which is aligned in a direction oblique or transverse to the first structural component and co-operates with an interconnecting option of the other structural component via an opening in the first structural component.
  • the invention is thus based on the problem to develop further a shear connector of the type initially mentioned and a system of interconnected structural components, respectively, such that an amplified spectrum of application results and/or enhanced application options may be obtained.
  • the assembly is to be simplified and higher forces are to be transmitted through the connection of the structural components.
  • the system should be adapted to be distinguished by an appealing optical appearance.
  • the connecting means are appropriate for forming a positive and/or non-positive joint.
  • the shear connector is preferably partitioned along a plane containing its longitudinal axis.
  • a groove and tongue system having an undercut may be provided as means for connecting the at least two parts of the shear connector, wherein each part of the shear connector comprises one part of the groove and tongue system.
  • a groove of dovetail-shape and a correspondingly shaped tongue have proved of value as the groove and tongue system.
  • the groove and tongue system may extend in the direction of the longitudinal axis of the shear connector. In this case preferably only one single groove and tongue system may be arranged on the parts of the shear connector. However, it is also an option that the groove and tongue system should extend in a direction transverse to the longitudinal axis of the shear connector. In this case particularly two groove and tongue systems on the parts of each shear connector have proved to be advantageous.
  • the groove and tongue system may, when seen in the direction of insertion of the tongue into the groove, have an altering width.
  • the groove and tongue system has, when seen in the direction of insertion of the tongue into the groove, a tapering extension.
  • the angle of tapering may advantageously be between 0.5° and 5°, and it is of particular advantage if it is between 1° and 3°.
  • the insertion of the one part of the groove and tongue system into the other one may be simplified in that the groove and/or the tongue has/have a chamfer of insertion in one of their end regions.
  • the connecting means may, according to an alternative embodiment of the invention, have a pin-shaped connecting element which is adapted to be inserted into one bore, each, in each one of the parts of the shear connector, wherein the axis of the bore forms an angle with the longitudinal axis of the shear connector.
  • the angle between the axis of the bore and the longitudinal axis of the shear connector preferably is between 15° and 80°, in particular between 30° to 60°. It is also impossible to align the bores transversely to the longitudinal axis of the shear connector.
  • the pin-shaped connecting element may be designed as a conical pin, and the bores within the parts of the shear connector may have a shape corresponding to the outer contour of the pin.
  • Each part of the shear connector may have, when seen in a section perpendicular to the longitudinal axis of the shear connector, a triangularly-shaped outer contour such that two composed parts result in a shear connector which has a square or lozenge-shaped cross-sectional face.
  • An alternative embodiment of the invention aims at a shear connector which has a bore passing therethrough along its longitudinal axis. It is possible to obtain a more stable and solid connection between the shear connector and the structural components to be connected if the bore is provided with a thread in one of its end regions.
  • the core diameter of the thread may preferably be smaller than the diameter of the bore.
  • the length of the thread in the direction of the longitudinal axis of the shear connector preferably extends over no more than 50% of the total length of the shear connector; most preferably the longitudinal extension of the thread will be only up to maximally 33%, in particular up to 25% at the maximum of the total length of the shear connector.
  • a shear connector on which there is arranged at least one plane-shaped retaining section is provided.
  • At least one plane-shaped retaining section may be arranged on both sides of the longitudinal axis of the shear connector. It is also possible that the at least two plane-shaped retaining sections lie within a mutual plane.
  • the mandrels may only project in one direction into corresponding recesses within the structural component and the shear connector may be fixed by means of the plane-shaped retaining sections, for example by means of screws on one outside of the structural component, with the screws passing through bores in the plane-shaped retaining sections.

  • the plane-shaped retaining section is arranged on the shear connector such that its normal of the surface extends parallely of the longitudinal axis of the shear connector or that it includes an angle of less than 45° therewith.
  • the plane-shaped retaining section can be arranged in an axial end region of the shear connector, and according to an alternative embodiment thereof it may well be arranged thereon adapted to be adjustable in the direction of the longitudinal axis of the shear connector. Also in this case provision may be made that the mandrels are only arranged on one side of the shear connector.
  • this one-piece shear connector has, when seen in a section perpendicular to its longitudinal axis, a triangular outer contour, wherein the parallely extending mandrels are expediently only provided on both of the smaller lateral faces of the shear connector.
  • the at least one plane-shaped retaining section and the shear connector may be moulded in one piece. Alternatively, however, it is also possible that the at least one plane-shaped retaining section is welded, soldered, screwed and/or glued to the shear connector.
  • the system of interconnected structural components according to the invention i.e. the supporting framework system, comprises a first structural component in which the at least one shear connector provided with mandrels is embedded, wherein the mandrels engage the first structural component as well as at least one further structural component.
  • the proposal according to the invention aims at the shear connector having a bore passing therethrough along its longitudinal axis, in which bore a pole- or rod-shaped retaining element, in particular a tube can be inserted, wherein the pole- or rod-shaped retaining element can be fixed in the direction of its longitudinal axis with respect to the shear connector and relative to the further structural component and/or to a further shear connector.

  • the pole-shaped retaining element may project axially beyond the shear connector. Furthermore, one retaining pin each may be arranged directly on the shear connector's axial end facing away from the other shear connector.
  • the retaining pin may be a pin made from steel and have a diameter of between 3 mm and 10 mm, preferably a diameter of between 5 mm and 7 mm. Furthermore the assembling of the system may be facilitated if the retaining pin has a chamfer or point at one of its axial ends.

  • FIGS. 13 through 20 concern further embodiments of the shear connector in which the latter is provided with at least one plane-shaped connecting section.
  • a shear connector 4 may be seen which laterally has two plane-shaped connecting sections 25 .
  • the connecting sections 25 have been moulded simultaneously with the shear connector 4 , so that a one-piece interconnection is accomplished.
  • Each connecting section 25 has at least one bore 26 by means of which it is possible to screw-attach the shear connector on the surface of a structural component. Then the mandrels will only protrude into the corresponding recesses of the structural component in one direction. Therefore, the shear connector 4 shown in FIGS. 13 through 20 has only been provided with mandrels 6 which extend in one direction away from the basic body of the shear connector.
  • FIGS. 17 through 19 show the shear connector 4 by way of an alternative embodiment.
  • only one single plane-shaped retaining section 27 has been provided, which is aligned such that the normal N of its surface extends parallely to the longitudinal axis L of the shear connector 4 .
  • the solution according to FIG. 19 combines such a retaining section 27 with the retaining sections 25 which may be seen in FIGS. 13 through 17 .
  • the shear connector 4 may be provided without (s. FIG. 17 , 18 ) as well as with a through bore 23 , which may be designed with or without thread 24 (s. FIG. 19 ).
  • FIG. 20 shows an example of application in which the shear connector 4 according to FIG. 17 and 18 , respectively, is used in order to interconnect two structural components 1 , 2 .
  • the retaining section 27 forms a solid support on the structural component 1 in order to fix the structural component 2 in relation thereto.
  • the fixing of the retaining section 27 is brought about by screws which are screwed through bores 28 .
  • FIG. 13 through 20 are particularly advantageously and preferably adapted for restoring wooden frameworks.
  • FIGS. 21 through 23 it is shown how a system of structural components 1 , 2 and 3 can be interconnected in a simple manner by means of two shear connectors 4 .
  • the structural component 1 support
  • the structural component 1 has a transverse bore 29 through which a tube 30 (preferably a steel tube) may be inserted.
  • Both shear connectors 4 are equipped with a through boring along their longitudinal axes.
  • the tube 30 will be selected to be sufficiently long so that both shear connectors 4 may be penetrated completely and that, moreover, some portion may even project axially.
  • FIG. 21 shows that the shear connectors 4 are tied in the structural components 2 or 3 (waler) in a manner as explained in context with FIG. 1 .
  • FIG. 22 a pre-assembled installation situation is represented in which the tube 30 has been pushed through the bore 29 in the structural component 1 and in which the two structural components 2 and 3 have been added laterally such that the tube 30 penetrates both shear connectors 4 .
  • the fixing of the interconnection is performed by means of steel pins 31 which are driven-in in the shown manner after the pre-assembly represented in FIG. 22 .
  • a preferably tapered steel pin 31 is driven-in such that it passes through the structural component 1 including the tube 30 ; thus, the tube 30 is fixed in relation to structural component 1 .
  • the two other steel pins 31 are driven through the structural components 2 and 3 transversely such that the tube 30 is penetrated immediately in the axial end region of the shear connector 4 .
  • the tube 30 is also fixed in relation to the respective shear connector 4 so that altogether a firm interconnection between the three structural components 1 , 2 , 3 has been brought about.
  • Corresponding bores for the steel pins 31 may be installed in advance in the structural components 1 , 2 or 3 and, if necessary, as well in the tube in order to facilitate assembling.
  • the bores may be pre-drilled with a diameter of 5 mm, and subsequently the steel pins having a diameter of 6 mm may be driven-in. Finally the entrance bores of the steel pins may be closed by means of wooden plugs.
  • the shear connector may be provided with moulding bevellings of e.g. 2° and have radii which, for example, amount to at least 2 mm.
  • the radii of the mandrels are designed such, in relation to the basic body of the shear connector that no embossments result and that the shear connector fits solidly and snugly in milled-out portions having been provided for the purpose of its reception.
  • the shear connector may be provided with a layer of zinc, with typical thicknesses of the layers amounting to between 5 and 8 ⁇ m.
  • the geometrical dimensions of the shear connector as well as of the possibly existing bores therein depend on the respective case of application. For example in the case of a cross-bracing-connection wood screws having a diameter of 12 mm may be applied leading to corresponding dimensions of the shear connector. Also the length of the shear connector is selected in accordance with the forces to be transmitted.
  • the proposal according to the invention is appropriate for connecting stem-shaped or plane-shaped structural elements.
  • examples of application are to be seen in attachments of wall boards in wood structure components.
