  • a simple way of arranging differently angled framing members is achieved.
  • a stop element is provided at an end of the recess to correctly position the heads in the axial direction of the recess when being fitted into the recess.
  • a stop element is provided at an end of the recess to correctly position the heads in the axial direction of the recess when being fitted into the recess.

  • Figs. 1-c show three different views of a truss structure 1 for supporting a solar panel arrangement.
  • the truss structure comprises five elongated framing members 3 extending in the longitudinal direction of the truss structure 1 , and a plurality of elongated framing members extending transversely 5 to the longitudinal direction.
  • the elongated framing members 3, 5, such as struts and chords, are connected by means of a connection arrangement in the form of node elements 7 forming the network of the truss structure 1.
  • node elements 7 are employed.
  • On top of the truss structure 1 eight longitudinal profiles 9 are arranged. However, these profiles 9 do not have any structural function in the truss structure 1 itself, but instead serve as attachment profiles for not shown solar panels.
  • Figs. 2a-c show three different embodiments of node elements 7 according to the present invention, where a middle node element depicted in fig. 2a corresponds to the encircled node element denoted A in fig. lc, a top node element in fig. 2b corre- sponds to the encircled node element denoted B in fig. lc, and a lower node element in fig. 2c corresponds to the encircled node element denoted C in fig. lc.
  • the node elements 7 have been manufactured in an extrusion process thus forming a profile having the same cross-section in the direction of the extrusion. Such elongated pro- files are thereafter cut into sections of predetermined lengths so as to form a complete node element 7.
  • the node elements 7 comprise a first holding means 1 1 for holding the framing members 3 extending in the longitudinal direction of the truss structure 1 , i.e. in the direction of extrusion, and at least one second holding means 13 for holding at least one framing member 5 extending transversely to the longitudinal direction of the truss structure, i.e. transversely to the direction of extrusion.
  • the node element 7 in fig. 2a comprises four second holding means 13
  • the node element in fig. 2b comprises two second holding means 13
  • the node element in fig. 2c comprises three second holding means 13.
  • Each second holding means 13 is adapted to hold 1-3 elongated framing members 5, each extending in different transverse directions. This will be more fully described below.
  • the first holding means 1 1 is constituted of a circular hole 1 1 with a centre axis extending in the longitudinal direction of the truss structure 1 , i.e. in the direction of extrusion. Consequently, the longitudinal framing members 3 which are in the form of circular tubes are inserted into the holes 1 1.
  • the inner surface of the holes is provided with an axial ridge 15 while the outer surface of the tube is provided with a corresponding mating longitudinal groove 17 and the ridge 15 will slide in the groove 17 when the tube is inserted into the hole 1 1. As a consequence rotation of the tube 3 when fitted in the first holding means 1 1 is prevented.
  • a self-tapping screw 19 or similar means is extending perpendicularly through the node element material into the hole 1 1 so as to prevent the tubes 3 from moving in the longitudinal direction when it has been fitted into the hole 1 1 (see fig. 3 a).
  • the second holding means 13 of the node element 7 is described with reference to fig. 3a-c showing the middle node element depicted in fig. 2a, but the same principals apply to the top and bottom node elements depicted in fig. b-c, respectively.
  • the middle node element 7 comprises four second holding means 13 adapted to hold elongated framing members 5, such as struts and chords, extending in directions being transverse to the longitudinal direction of the truss structure 1 , i.e. transverse to the direction of extrusion of the node element 7.
  • Fig. 3a-c shows the middle node element 7 in the longitudinal direction of the truss structure having elongated framing members 5 in the form of hollow tubes 5 attached to a corresponding second holding means 13.
  • the framing members are provided with end pieces 21 for connecting the framing members 5 to the node elements 7.
  • the end pieces 21 are separate parts and each end piece com- prises a shaft 23 having a substantially rectangular cross-section and a head 25 which connects to the shaft 23.
  • the head 25 is adapted to be locked in the node element 7 while the opposite shaft end is adapted to be locked within the tube 5 of the framing member. This can be accomplished in several ways, e.g. by means of not shown self-tapping screws extending through the tube wall or by clamping the tube wall onto the shaft end.
  • Each second holding means 13 is provided with a recess 27 extending in the direction of extrusion of the node element 7.
  • the recess 27 is formed by means of first and second jaw halves 29, 3 1 which together define the recess and form a gap 33 between them.
  • the gap 33 opens in a direction being transverse to the direction of extrusion.
  • the recess 27 can be divided into two sections both extending in parallel and in the direction of extrusion, i.e. an outer and an inner section.
  • the first section 27 is somewhat larger than the second section, when seen in the direction of extrusion of the node element 7, and is adapted to contain the heads 25 of the end pieces 21.
  • the second section 27 is adapted to contain a wedge element 35 in the form of a pin 35 so as to wedge the heads in the first section 27.
  • the head 25 of the end piece 21 is inserted in the recess 27 in the direction of extrusion of the node element 7.
  • end pieces 21 can be fitted in a side-by- side arrangement (even though larger numbers of end pieces can be contained if the node element and the end pieces are configured differently).
  • a first stop element 37 is arranged at one end of the recess 27 so that the head 25 will abut against the stop element 37 when it is fitted into the recess 27.
  • a second stop element 37 is fastened at the other end of the recess to prevent the end pieces to move in the axial direction of the recess.
  • the stop element 37 can for example be a self-tapping screw 37 which has been screwed into the material of the node element 7 adjacent the end of the recess 27 so it partly blocks it.
  • the head 25 is larger than the size of the gap 33 so when it has been inserted into the recess 27 it can not escape through the gap 33. Instead the shafts 23 of the end pieces 21 protrude through the gap 33 in a direction defined by the inclination of the shaft 23 in relation to the head 25. As seen in fig.
  • the wedge element 35 which is in the form of an elongated pin 35 having a length equal to the length of the recess is also inserted (after the end pieces have been positioned in the recess) in the second section of the recess so that it will be located adjacent the top of each head 25.
  • the pin 35 is preferably fitted into the recess 27 by means of a sledge hammer or similar means.
  • the diameter of the pin is adapted so it will act on the head 25 and press it against the outermost inner surfaces 39 of the jaw halves 29, 31.
  • the top of the head is provided with two ridges 41 extending in the direction of the recess. Due to the ridges 41 the friction work to be overcome when forcing the pin 35 into the recess is decreased.
  • each jaw half 29, 31 is inclined in a convergent manner as seen in a direction out of the gap 33.
  • the head 25 comprises inclined surfaces 26 which are mating with the inclined inner surfaces 39 of the jaw halves, i.e. having a complementary form. Due to the complementary surfaces of the head and the jaw halves, the head will adopt a position where the surfaces are abutting each other in a mutual parallel arrangement when the pin 35 is acting on the head 25 and forces it towards the inner faces of the jaw halves 29, 31.
  • the shafts 23 of the end pieces will protrude from the gap in a more accurate way since the inclined surfaces will cooperate so as to adjust the position of the head in a plane being perpendicular to the direction of extrusion.
