Definitions

  • the invention relates to a wooden bar construction with a first bar support member and at least one second bar support member which are non-positively connected to each other in a node, according to the preamble of patent claim 1.
  • Wooden bar structures composed of individual bar supports are known above all as static load-bearing structures for buildings, halls, roofs and the like, but also as load-bearing structural elements such as truss girders, masts etc. They are used both for producing flat and three-dimensional structures.
  • Characteristic of such bar constructions is that the individual bar support members, such as round or square timbers, converge like a truss in nodes. Since the power flow follows the longitudinal axes of the bar support members, this results in a load concentration and load deflection in the nodal area. The highly loaded nodes in this way is thus of central importance within the entire rod construction.
  • connection surfaces for the individual bar support members it is known to provide a node plate in the node, which has connection surfaces for the individual bar support members.
  • the node may be formed so that the connection surfaces are within the wood cross section, to which the bar support member is slotted normally, or outside of the wood cross section, for example, in gusset plates with shoe-shaped receptacles, in which the ends of the bar support members are inserted.
  • the frictional connection between gusset plate and bar support member is usually carried out across transversely to the rod support member longitudinal axis in the bar support member introduced dowels or nailing.
  • the invention has the object to improve the load transfer behavior of rod structures in their nodes and to minimize load-induced deformations.
  • the basic idea of the invention is to provide a molded body in the junction of a wooden bar construction which has defined force introduction surfaces for connecting a plurality of bar support members.
  • the inventive design of the connection between the molded body and the rod support members any slip is eliminated from the rod construction in the connection area, with the advantage that deformations occur within the rod construction in only a small extent.
  • a further advantage of the invention results from the load transfer behavior typical of bar structures, in which essentially only tensile and compressive forces occur in the individual bar support members, which are deflected at the junctions. In known rod constructions, this leads to an unfavorable stress of the rod support members in the node, since the introduction of force is directed obliquely to the fiber.
  • the moldings replace the bar support members in the nodes, so that the bar support members are claimed only fiber parallel.
  • This has the advantage that the inhomogeneous and anisotropic material properties of the material wood in the heavily loaded node at force application obliquely to the fiber are no longer relevant for the dimensioning of the rod support members.
  • the bar construction can therefore be designed not only more efficient and economical, but also slimmer and therefore more aesthetic.
  • the shaped body is preferably produced by the casting method, 3D printing process or by milling from a solid material and consists of mineral casting, preferably of a polymer-bound concrete.
  • This has the advantage that even spatially complex shapes can be realized in a simple manner.
  • the strengths of the molded body are far above those of the bar support member to be connected, with the advantage that high-strength moldings are available for load transfer within the bar construction in areas with high load concentration, while in less stressed areas, the comparatively lower strength of the wooden bar support members sufficient for the load transfer.
  • a nodal point according to the invention does not structurally impart a joint, but is able to absorb and transmit bending moments to a certain extent. This property can be improved if the connection of a bar support member to a shaped body has two or more rod-shaped, laterally spaced connecting elements, one of which acts under load as a push rod and another as a pull rod.
  • a force-transmitting pressure element is arranged between the first force introduction surface of the shaped body and the end of the first rod support member. Due to its homogeneous material properties, the pressure element ensures a defined force transmission from the rod support member to the molded body, independent of the imperfections of the material wood.
  • the pressure element is positively embedded in a recess at the end of the rod support member and / or in the force introduction surface of the shaped body, whereby a positional fixation of the pressure element is first achieved.
  • the pressure element can be made of a material with ductile properties, which allows the reduction of stress peaks by deformation-induced load transfer. According to the invention, plastics with elasto-plastic behavior or suitable elastomers are preferred for this purpose.
  • Suitable pressure elements consist for example of elastomers, preferably of Cloroprene rubber or natural rubber, in which optionally reinforcement inserts can be integrated.
  • the pressure element On its front side facing the shaped body, the pressure element can be provided with a profiling, so that transverse forces are not removed by the rod-shaped connecting element only in the transverse force load in the connection area, but also on the pressure element.
  • a pressure element with a cylindrical or disc-shaped shape, which sits coaxially on the rod-shaped connecting element. In this way, an extremely compact node structure is realized, which allows to lead several rod support members in the node together, without these interfere with each other.
  • Another embodiment provides, instead of the pressure ring to introduce a hardenable potting compound in a corresponding cavity, the potting compound thus forms the pressure element after setting.
  • the potting compound adapts to the local geometric conditions at the junction and is therefore able to compensate for production or assembly-related tolerances.
  • the potting compound can have the same material properties in the set condition as the pressure element.
  • Another embodiment of the invention combines the two above-described solutions and their advantages by a pressure ring between the rod support member and molded body is arranged, which also forms the cavity for the potting compound at the same time.
  • the connecting elements are preferably glued or screwed into the bores.
  • the Fig. 1 and 2 1 shows a diagonal strut whose longitudinal axis 3 extends at an angle ⁇ to the longitudinal axis 4 of the second bar support member 2, for example a support.
  • a Shaped body 6 arranged in Fig. 2 is shown on a larger scale in an oblique view.
  • the molded body 6 is formed as a monolithic cast body 2 and has approximately wedge shape.
  • the molded body 6 consists of polymer concrete, ie it is composed of a mineral aggregate and a polymer matrix as binder, this mixture optionally also being able to contain fibers for reinforcing and increasing the strength.
  • the molded body 6 has a first force introduction surface 7, which runs perpendicular to the longitudinal axis 3 of the first rod support member 1.

  • the second force introduction surface 9 has a rectangular ground plan and, in the case of a round timber, runs curved as a second bar support member 2 and, in the case of a square timber, as a second bar support member 2.
  • the force introduction surface 9 may be provided with a profiling in order to bring about a toothing with the circumference 5 of the second rod support member 2 in order to increase the transferable force.
  • a recess 10 At the intersection of the longitudinal axis 3 with the second force introduction surface 9 can be seen a recess 10 having a preferably cylindrical shape.
  • the lateral surface of the molded body 6 results essentially from the entirety of all the generatrices of the first force introduction surface 7 and second force introduction surface 9. This results in a spatially convex shape of the shaped body 6.
  • a shaped body 6 according to the invention is penetrated by two approximately parallel channels 11, which extend from the peripheral surface 12 lying between the first force introduction surface 7 and the second force introduction surface 9 to the second force introduction surface 9 and thereby directed perpendicular to the longitudinal axis 3 Course ends at the height of the recess 10 or higher.
  • the channels 11 serve to receive and guide fasteners, not shown.
  • the molded body 6 lies in its intended use with the second force introduction surface 9 over the entire surface on the circumference 5 of the second rod support member 2.
  • a nail-like driven into the second bar support member 2, with its head positively engaging in the recess 10 centering mandrel 15 ensures the intended relative position of the shaped body 6 relative to the second bar support member 2.
  • the load-bearing fastening means are in the Fig. 1 and 2 not shown, however, consist of high-strength bolts that extend through the channels 11 and extend with their threaded portion each in the solid wood of the second bar support member 2.
  • the channels 11 may be formed by sleeves embedded in the shaped body 6.
  • the second bar support member 2 may have at its periphery an axially acting abutment surface which receives the parallel to the longitudinal axis 4 force component from the shaped body 6.
  • the diameter of the blind hole 17 preferably corresponds to that of the cylindrical cavity 8 in the molded body 6.
  • the blind hole 17 intersects with a likewise extending from the end face 16 and extending coaxially to the longitudinal axis 3 circular cylindrical recess 18 with a larger diameter compared to the bore 17 and lower axial depth. Together, the blind hole 17 and the circular cylindrical recess 18 a kind of stepped bore at the end of the first rod support member 1. For the inventive design of the node, the provision of the recess 18 is indeed advantageous, but not essential. Likewise, only the blind hole 17 could be arranged in the force introduction surface 7.
  • the connecting element 19 consists in the present example of a Steel bar with profiled peripheral surface, preferably with a circumferential external thread to improve the power transmission between the connecting element 19 and the first bar support member 1.
