Definitions

  • the invention relates to a lattice girder made of wood for the construction sector with an upper belt and a lower belt, which are connected by struts, which each have at their ends pins, the pins of one end of the struts in grooves of the upper belt, the run in the longitudinal direction of the upper belt, are glued and the pins of each of the other end of the struts in grooves of the lower belt, which extend in the longitudinal direction of the lower belt, glued.
  • Such lattice girders are used, for example, as a carrier in a formwork of concrete structures to be concreted, in particular of concrete ceilings and walls.
  • Generic lattice girders are eg from the documents DE 18 07 956 B1 . DE 18 17 718 A1 . DE 2242329 A1 or US2780842A known.
  • these lattice girders there are grooves in the straps which extend in the longitudinal direction of the straps, the side surfaces of the grooves being aligned parallel to one another. These grooves are usually milled.
  • the pins are worked out of the ends of the struts. Since the struts in generic lattice girders are usually oblique, with an angle of about 45% on the straps, the pins have a triangular basic shape in their plane parallel to the longitudinal direction of the struts.
  • the pins are formed by introducing parallel to this longitudinal sections cuts in the ends of the struts. So they also have mutually parallel side surfaces.
  • wood glue is applied to the side surfaces of the pins and / or the grooves. Since the pins and the grooves, worked according to a tongue and groove connection on fit, the glue is displaced during the insertion of the pins in the grooves of the side surfaces in the groove bottom. In the case of a poor tolerance position, therefore, there is often too little glue left on the side surfaces in order to ensure a permanently firm gluing.
  • the US 3,452,501 discloses a wooden lattice girder for the construction sector with an upper girth and a lower girdle joined together by struts which each have pins at their ends.
  • the pins are each one end of the struts in grooves of the upper belt, which run in the longitudinal direction of the upper belt, glued and the pins of each of the other end of the struts in grooves of the lower belt, which run in the longitudinal direction of the lower belt glued.
  • the grooves are not adjusted in length to the dimensions of the pins but extend along the entire length of the straps.
  • the grooves are adapted to the dimensions of the pins. These grooves have a diamond-shaped cross-section.
  • the not adapted to the dimensions of the pins grooves have the disadvantage that dirt and / or water can penetrate into the grooves. The latter can lead to premature loosening of the glue.
  • the grooves can be performed with diamond-shaped cross-section. However, these are very expensive to produce. Even with a milling cutter, the grooves with diamond-shaped cross-section would be very difficult ausformbar.
  • the invention has for its object to provide a lattice girder and a method for producing the lattice girder, which avoids the disadvantages of the prior art, in particular a permanently strong connection between the straps and the struts is achieved in a wider tolerance range, with a simple production the lattice girder should be possible.
  • the lattice girder according to the invention made of wood for the construction sector has an upper belt and a lower belt, which are interconnected by struts on.
  • the struts have each at the ends of pins, wherein the pins of one end of the struts in grooves of the upper belt which extend in the longitudinal direction of the upper belt, glued and the pins of the other end of the struts in grooves of the lower belt, the run in the longitudinal direction of the lower belt, are glued.
  • the length of the grooves in the longitudinal direction of the straps at least substantially corresponds to the dimensions of the pin or pin inserted and glued into the respective groove, ie the grooves only extend over a partial length of the straps.
  • the side surfaces each extending in one of the grooves in the longitudinal directions form an acute angle and the surfaces of the pin glued into these respective side surfaces with these side surfaces enclose a corresponding acute angle.
  • the pins are tapered by the inclusion of the acute angle from the side surfaces towards their ends and the width of the grooves perpendicular to the longitudinal direction of the straps decreases correspondingly towards their respective groove bottom.
  • the cross sections of the grooves are rectangular or substantially rectangular. The cross sections of the pins inserted into the grooves are formed accordingly so that a snug fit of the pins is achieved in the grooves. If several pins inserted into a groove, so is the cross section of the Spigot formed in the groove structure used in accordance with rectangular.
  • the pins can fill and seal the volume of the grooves in such a way that no contaminants can penetrate into the grooves.
  • the rectangular design of the cross sections of the grooves allows easy production of the lattice girder according to the invention, since such grooves can be easily prepared by means of circular saw blades. In this case, at least two circular saw cuts are introduced, each with an angle to each other angled cutting plane to form a groove in a respective belt.
  • the ends of the struts each have two pins, a construction with high load capacity is achieved without too high production costs for forming the structures to be glued.
  • a gap Preferably lies between the nutground remedyen end of the pin and the groove bottom of the groove into which the respective pin is glued, a gap.
  • This space can be the Leimmengen, the Assemble the struts with the straps are displaced by the pressing of the side surfaces of the pins on the side surfaces of the grooves record, so that insertion of the pins in the grooves is possible without resulting from these Leimmengen displacement resistance.
  • the grooves of the grooves in the longitudinal direction of the straps each have a semicircular profile
  • the grooves can be cut by means of several inclined saw blades successively in the rotating belt.
  • two adjacent struts are interlinked in the region of their ends glued in grooves of one of the straps. This allows power transmission from strut to strut. A transverse load can be better absorbed by the lattice girder according to the invention.
  • the glued ends are preferably interlocked with each other via a fine galvanizing of adjacent pins.
  • Fine galvanizing forms a high contact surface due to the zigzag shape of the surfaces to be joined formed by the fine galvanizing. When gluing such trained contact surfaces a great strength is achieved.
  • the mutually toothed ends in the longitudinal direction of the straps each form a semicircular profile.
  • the corresponding edges of the obliquely adjacent to each other Struts then have an elliptical shape together with the semicircular profile.
  • Such shaped toothed ends, or pins, are according to the invention accurately positioned in correspondingly shaped grooves.
  • the contact surfaces to be bonded that is to say the side surfaces of the pins and the associated side surfaces of the grooves, are maximized in terms of their area, which leads to particularly strong gluing and thus to particularly stable lattice girders.

  • the pins 7 each one end of the struts 2 are thus glued into grooves 9 of the upper belt 4 and the pins 7 each of the other end of the struts 2 are glued into grooves 9 of the lower belt 5.
  • each of a groove 9 forms an acute angle
  • the surfaces 10 of the peg 7 glued into these respective side surfaces 12 enclose a corresponding acute angle.
  • the respective side surfaces 10,12 of the pin 7 and the grooves 9 are therefore not parallel to each other.
  • the pins 7 thereby taper towards their ends. Accordingly, the width of the grooves 9 decreases perpendicular to the longitudinal direction of the straps 4,5 in the direction of their groove bottom by the inclusion of the acute angle.
  • the pins 7 are glued in the grooves 9 with their respective side surfaces 10,12 fit. In each case two adjacent struts 2 are interlocked in the region of their glued in grooves 9 of the straps 4.5 ends.
