Definitions

  • the present invention refers to a building member such as a beam, a girder or the like incorporating two mainly parallel, elongated edge elements of wood and a number of spaced apart supporting members interconnecting said edge elements.
  • the frame timber or the struts have been provided with cylindrical end taps, which have been introduced into cylindrical holes in the edge element surfaces facing each other, whereupon the end taps have been glued and/or nailed to the edge element.
  • the struts have to be inclined against each other for allowing the structure to take up forces also in its longitudinal direction it is necessary for producing such structure elements in an automatic machine to build a very complex machine, which thereby should be very expensive.
  • the alternative is to manufac- tare the element manually, which of course will make the manufacture considerably more expensive.
  • interspacing supporting members formed as zigzag-bent coarse steel wire, which are attached between the halves of the divided edge elements, which are thereafter joined in suitable manner.
  • This design can presumably be manufactured in automatic machines of not too complex design but certain problems can be expected when it concerns the attachment of the wire between the edge element halves.
  • Another drawback with this design is that steel wire of this dimension and having the properties required is comparatively expensive and it is expected that the price of the wire will nearly correspond to the price of the wood it shall substitute.
  • the purpose of the present invention is to provide a building member such as a beam, a girder or the like comprising two substantially parallel, elongated edge elements of wood and a plurality of spaced apart supporting members interconnecting said edge elements, which building member has the advantages of the building members referred to hereabove but which as far as possible is free from the drawbacks from which the older designs have suffered and which is easily manufactured with simple and reliable machines and the invention is characterized mainly thereby that the supporting members are wooden struts, the end portions of which are each designed with at least a first portion situated at a distance from its adjacent end and having a smaller section thatan a second portion situated closer to said end, and that said end portions are fitted in holes in the edge element surfaces facing each other, said holes having a section being a complement to the end portions of said struts.
  • FIG 1 is shown in a schematic cross section a wall girder 1 according to the invention.
  • This wall girder rests via a sill 2 on a bottom plate 3 and it comprises two elongated, mutually parallel edge elements 4, which are spaced apart by means of an intermediate piece 5 and a plurality of inclined struts 6 spaced apart in the longitudinal direction of the girder and interconnecting the two edge elements 4.
  • figure 2 a modified embodiment of the invention in which the girder incorporates two edge elements 4, which are spaced apart by an intermediate piece 5 and a number of struts 7 arranged mainly perpendicularly to the longitudinal direction of the edge elements.
  • the girder shown in figure 2 has a very low ability of taking up loads in directions perpendicular to the extension of the struts but in cases where no such loads are expected this type of girder is a suitable design as it is more simple to manufacture than the design according to figure 1.
  • Figure 3 shows schematically a part of a strut 6, 7 having an end portion 8, which is formed tapering with a first portion 9 situated at a distance from the end of the strut, which first portion has a smaller cross section than a second portion 10 situated closer to the end of the strut.
  • the edge element is in this case divided in two halves 4a, 4b, which in the surfaces of division are provided with recesses or turned cavities lla, 11b, which together form a hole 11, which essentially corresponds to the section of the end portion 8 of the strut 6, 7.
  • the end portion 8 of the strut is fitted in the direction shown with the arrow in figure 3 between the halves 4a and 4b, which are thereupon moved against each other as shown with the arrows until the edge element halves will abut each other, whereupon the halves are connected in any suitable manner, e.g. by glueing or by nail joints 12 to the shape shown in figure 4.
  • the strut 6, 7 is well locked in the hole 11 in the edge element 4 as the outlet side of the hole is smaller than the largest dimension of the end portion of the strut, i.e. at the second portion 10.
  • Figures 5 and 6 show in views corresponding to figure 7modified embodiments of end portions 8 of struts and of hole in the divided edge element respectively.
  • the embodiment according to figure 5 is instead equipped with an annular groove 9b with straight walls, which groove has been recessed in the end portion of the strut and which at the end side of the shut leaves a second portion 10b having a larger section than the recessed portion.
  • the halves 13a and 13b of the hole form in the corresponding way as in figure 3 a hole, which has a section corresponding to the end portion 8 of the strut.
  • the end portion 8 of the strut has an annular ridge-formed portion 9c at a distance from its end and between this annular portion 9c and the end a portion 10c of less diameter whereas the strut inside the ridge-formed portion has a portion smaller than the annular ridge-portion 9c.
  • the annular ridge-formed portion 9c to be considered as the second-portion whereas the portion of the shut situated inside the second portion is considered as the first portion of the shut end.
  • the end profile of the shut thus comprising a first portion, a second portion 9c of larger diameter and an outer portion of the same diameter as said first portion corresponds to a hole in the edge element, which hole is formed by hole parts 14a, 14b. In both cases the end portions of the are connected to the holes in the same manner as shown in figure 4.
  • FIG 7 a modified embodiment where an edge element made in one piece is provided with a hole 15, which has a uniform section mainly corresponding to the section of the strut 6, 7.
  • the end portion 8 of the strut is here provided with a first portion 16, which is recessed or turned down and a second portion 17 situated between said first portion and the end of the strut, which second portion 17has the same dimension as the hole 15 and preferably also as the remainder of the strut 6, 7.
  • FIG 8 is shown how the strut end portion 8 has been entered into the hole 15 in the edge element 4.
  • a mouldable and cureable compound is applied or injected respectively through a bore in the wall of the edge element, which compound 18 will fill the space between the wall of the hole and the first portion l6 of the end portion of the strut.
