Definitions

  • the present invention relates to a structural element for constructing a projectile, with a support made of wood with a top, a bottom, two flanks and two end faces, the wood fibers are oriented at least partially in the carrier longitudinal direction.
  • the invention further relates to a skeleton construction for constructing a projectile with the aid of such a component.
  • Beams made of wood for example glulam (BSH) are used in professional timber engineering because of their low weight and their high heat and fire resistance for large spans, e.g. used by hall roofs or as an intermediate carrier in multi-storey buildings.
  • BSH glulam
  • the high pressure loads of the hall roofs or floors can cause settlement processes in the wood, which can lead to subsidence cracks, gaps and leaks in the building.
  • the invention has for its object to provide a structural element for the construction of projectiles, which overcomes the disadvantages of the prior art.
  • This object is achieved according to the invention with a component of the aforementioned type, in which in at least one end of a wooden bar with a graded or gezinkten to the carrier center profile is recessed positively, which extends from the top to the bottom, whose stages or Tines run from the top to the bottom, and whose wood fibers are oriented substantially in the direction from top to bottom.
  • a pressure load reinforcement is created in the end region of the carrier, which has high strength due to the intimate form fit of the stepped or gezinkenten reinforcing rod.
  • the carrier may be processed like any other conventional carrier in construction, with the reinforcing rod providing a stable anchoring point for connection of fittings for connection to subsequent or overlying vertical components. Due to the final reinforcement according to the invention and carriers of fast growing woods, which have a lower bulk density and thus lower strength, can be used without affecting the compressive strength and thus settlement stability of the building. Also, the grained wood surface of the carrier is largely sealed by the embedded reinforcing bar, so that the risk of moisture penetration into the wood fibers or the glue of a BSH carrier and thus a tearing of the carrier is eliminated or at least greatly reduced.
  • the bar has a finger joint profile with at least two finger joints. This results in a particularly intimate fit of the finger joints of the reinforcing rod with the carrier and thus particularly high strength.
  • said reinforcing rod is recessed at a distance from the flanks and / or flush with the end face, which facilitates the processing of the beam in the manner of conventional wooden beams.
  • the carrier can basically be made of solid wood.
  • the carrier is made of glulam whose layers are parallel or normal to the top and bottom sides and in the longitudinal direction of the carrier.
  • flank angles of the finger joints of the finger joint profile are preferably self-locking in order to ensure a good absorption of force. It is also advantageous if the tips of the finger joints lie in one plane, which facilitates the milling of the finger joints in the wearer's end faces.
  • the side of the rod exposed on the front side has a recess for at least partially receiving a part of a coupling element. With the help of this recess, a pre-positioning of the coupling element can be achieved during its assembly. If the rod is made of harder wood than the carrier, thereby an improved anchoring of the coupling element is achieved at the end of the carrier.
  • the component can be further prefabricated for use on the construction site, by equal to the one part of a on the exposed side of the rod on the front side two-piece coupling element is screwed. The component then needs to be connected to the site only with the second, attached to a vertical component part of the coupling element.
  • the invention also provides various skeleton structures for constructing projectiles, each of which comprises at least one component of the type presented here and a vertical component.
  • the vertical member may be supported on the rod of the component, or conversely the member's rod may be supported on the vertical member, or the member's rod may lie between two superimposed vertical members to receive and transmit compressive loads.
  • a vertical component may be provided at its upper end with a shoulder corresponding to the height of the component, on which shoulder the rod of the component is supported, resulting in an improved positive connection between the vertical component and the component.
  • a coupling element one part of which is screwed to the component, in particular the exposed side of the reinforcing rod, and the other part of the vertical component.
  • a component 1 which has an elongate support 2 made of wood with upper and lower sides 3, 4, flanks (lateral sides) 5, 6 and end faces 7, 8.
  • an elongate support 2 made of wood with upper and lower sides 3, 4, flanks (lateral sides) 5, 6 and end faces 7, 8.
  • end faces 7, 8 each have a rod 9, 10 made of wood inserted in a form-fitting manner.
  • the carrier 2 may be a solid wood beam, or a carrier made of glued laminated timber (BSH), in particular glued laminated wood ("laminated beams"), the individual, here only exemplified layers 11-14 parallel or normal to the top and bottom sides 3, 4 of Carrier 2 can run, but in any case in the longitudinal direction R of the carrier 2. If the carrier 2 is made of solid wood, its wood fibers extend predominantly in the carrier longitudinal direction R; when the carrier 2 is made of layers 11-14, its wood fibers run at least in some, preferably in all, layers 11-14 in the carrier longitudinal direction R.
  • BSH glued laminated timber
  • laminated beams glued laminated wood
  • the wood fibers of the rods 9, 10 are oriented substantially in the direction from the top 3 to the bottom 4 of the carrier 2.
  • the rods 9, 10 thereby reinforce in the installed position of the device 1, the carrier 2 in its end portions against compressive loads in the vertical direction V.
  • Die Rods 9, 10 can - even if this is not mandatory - be made of a harder wood than the carrier. 2
  • Each of the bars 9, 10 has a finger jointing profile 15 pointing towards the center of the carrier 2, which engages positively in a complementary finger joint profile of the carrier 2 milled into the respective end face 7, 8.
  • the finger joints 16 of the finger joint profile 15 of each bar 9, 10 extend in the vertical direction V, i.
  • the tips 17 of the finger joints 16 of each bar 9, 10 may each lie in a plane E, in order to facilitate the milling of the complementary finger joint profile in the end faces 7, 8 of the carrier 2.
  • the flank angles of the finger joints 16 of the finger joint profile 15 are preferably chosen to be flat so that they are self-locking.
  • the rods 9, 10 may additionally be glued to the carrier 2.
  • the rods 9, 10 each with a distance A to the flanks 5, 6 of the carrier 2 inserted into this and close flush with the respective end face 7, 8 from.
  • the rods 9, 10 may be provided on their at the respective end face 7, 8 exposed side with a recess 18 to the assembly of a coupling element 19 (FIGS. Fig. 5 ) at the respective end face 7, 8 of the carrier 2 to facilitate.
  • Fig. 2 shows an alternative embodiment of the reinforcing rod 9 of the device 1, embedded in the end face 7 of the carrier 2. It is understood that a mirror-like in the opposite end face 8 a similar rod 10 is inserted can be.
  • the rod 9 of Fig. 2 has straight prongs 16, ie no wedge-shaped prongs.
  • Fig. 3 shows a further embodiment of the device 1 with a stepped profile 15.
  • the profile 15 has a plurality of steps 16 ', each extending from the top 3 to the bottom 4 in the vertical direction V and by means of which the rod 9 toward the center of the carrier 2 out rejuvenated.
  • Fig. 4 shows a further embodiment of the device 1, in which a plurality of rods 9 are recessed at mutual distances in the form of a rod group 9 'in the end face 7, wherein each individual rod 9 of the rod group 9' has a finger joint profile 15 with a single spline 16.
  • Fig. 5 shows an exemplary skeletal structure 20, as it can be used for the construction of floors 21, 22 of a (not shown) building.
  • the skeleton structure 20 comprises (at least) a component 1, which is connected via the coupling element 19 to a vertical component 23, here laterally.
  • the coupling element 19 may for example be a wood connector as is Euratsfeld, Austria, sold by Knapp GmbH, under the brand MEGANT ®.
  • the coupling element 19 comprises a first part 24, which is screwed to the side of the rod 9, 10 which is exposed on the end face 7 of the carrier 2 and can also be partially or completely received by the recess 18 of the rod 9, 10.
  • the second part 25 of the coupling element 19 is attached to the vertical component 23, for example screwed.
  • the coupling element 19 can by appropriate mating, locking, Latching, screwing, etc. of the two parts 24, 25 are closed.
  • Fig. 6 shows an alternative application of the device 1 in the context of a skeleton structure 26.
  • the skeleton structure 26 has (here) four vertical components 27-30, of which two vertical components 27, 28 and 29, 30 are arranged one above the other and between each one end portion of the device. 1 take up.
  • the bars 9, 10 of the component 1 lie in each case on the upper ends of the vertical components 27, 29, and the lower ends of the vertical components 28, 30 are supported on the upper sides of the rods 9, 10.
  • the compressive load of the upper projectile 22 via the reinforcing rods 9, 10 of the carrier 1 to the basement 21 is derived, and the reinforced by the rods 9, 10 compressive strength of the end portions of the carrier 1 reduces the risk of settling of the skeletal structure 26 and thus built structure over time.
