Definitions

  • the present invention relates to a reinforced structural member for use in applications where load carrying capability is required, for example structural, semi-structural and cladding applications to carry floor loading, walkway loading, wheeled loading, pressure loading in buildings, bridges etc.
  • an elongate structural member comprising:
  • the present invention provides a member which has improved strength characteristics by efficiently transmitting loads to the bottom corners or intermediate points across the section, while providing stiffness in the longitudinal direction, preventing local buckling of the wide upper flange and resistance to in-plane loading.
  • the space between the arcuate member and the load bearing surface opposing the arcuate surface may be filled with a foam material and/or may have rib members extending between them.
  • Both the outer shell and the arcuate member are constructed by either moulding or pultruding them from fibre reinforced composite materials. This provides the member with the strength required whilst retaining a lightweight construction.
  • connecting portions may be provided to allow attachment of the units to each other to form floors, decks, roofs, walls, beams and columns of buildings, bridges and other forms of structure.
  • hanger portions may be provided to allow attachment to the hanging means.
  • Figure 1 shows the basic configuration of a first embodiment of the present invention.
  • the structural member comprises an outer member consisting of the load bearing surface 1, two side faces 5 and 6, a fourth face 3, and an arcuate member 4.
  • Load applied to the structural member is passed through the load bearing surface 1 to the upper surface of the arcuate member 4.
  • the load is supported by the strength of the arch and is passed to the ends 4a.
  • As load is applied to the arch there is a tendency for the ends 4a to splay out unless they are restrained.
  • This is achieved by the fourth face 3 which in use provides a tensioning force for holding the ends of the arch together and hence holding the arch in shape.
  • the space 2 defined between the convex surface 8 and the inside of the load bearing surface is filled with a foam material to help to distribute the load evenly to the arcuate member.
  • the arcuate member 4 may be formed as a single unit with the outer member (1,3,5,6) or formed separately and inserted into the outer member subsequently. Reinforcements 9 may also be used in the corners of the outer member to increase the overall stiffness and strength of the structural member.
  • the reinforcement may be formed as part of the outer shell, part of the arcuate member or formed as a separate entity to be inserted into the outer member.
  • the outer shell and arcuate member may have a laminated structure or be formed in a single piece.
  • the structural member may also be constructed with or without a foam filling in the space 2 by using reinforcing ribs 21 to distribute the load more evenly onto the arcuate member, as shown in figure 2.
  • the ribs may extend parallel to the axis of the structural member and perpendicular to the load bearing surface as in figure 2.
  • there may be alternative ways of arranging the ribs for example a fan like arrangement where the ribs are parallel to the axis of the structural member and perpendicular to a tangent at the point of intersection with the arcuate member.
  • the structural members may also be used by resting them on supports or by hanging them from a hanging means such as wires. To this end the structural members may be provided with hanging portions 31 and 32 as shown in figure 3 to allow attachment to such a hanging means.
  • Figure 4 shows an alternative construction of the present invention comprising two arcuate members which intersect each other.
  • the second arcuate member 51 is curved in the opposite sense to the other arcuate member 4.
  • Extra ribs 21 and 52 may be included similarly to the ribs 21 shown in figure 2.
  • the spaces between the ribs may be filled with a foam material.
  • some or all of the ribs may be excluded completely whilst still using the foam filler as in the configuration shown for a single arch in figure 1.
  • the structural member may be used with several similar members adjacent to it to form a floor or deck and so on. They may also be configured with adjacent members perpendicular or at inclined angles. To accommodate this, connection portions 41-44 as shown in figures 5 & 6 may be included to facilitate connection to adjacent structural members or to inter-connect members as described below.
  • Figure 7 shows an example of two of the members shown in Figure 5 connected together by connection members 71.
  • the connection members have outstanding portions 74 which are shaped to engage the recess portions 41 provided on the structural member.
  • the two members to be connected are bonded together along their abutting surfaces 72 and to the connection members along interfaces 75 and 76.
  • the connecting members will be connected to each other via a web portion (not shown) which runs between the edges of the members 1.
  • the two members are slid into each side of the connecting member until the outstanding portions 74 engage the recess portions 41 such that the edge faces of the members abut against the web portion.
  • the edges of the members are bonded to the web portion as opposed to each other, as in the previous construction.
  • a bolt may be passed through the connection members and the structural members to clamp the parts together.
  • the possible positions of the bolts are indicated by dashed lines 73 in Figure 7.
  • Figure 8 shows an example of a connection member for connecting three structural numbers of the type shown in Figure 5. Again each of the three structural members is inserted into the D-shaped connection member to which they are subsequently bonded along the member's edge 83 and upper and lower 82 surfaces.
  • Figures 9A to 9D illustrate the various forms of connection member usable with the first connection system. This includes the cross junction of Figure 9A, corner junction of Figure 9B, T-junction of Figure 9C and a series junction of Figure 9D.
  • a connection method for the embodiments shown in Figure 6 comprises undercut recesses 43, 44 into which is inserted a connection member 100 having overhanging portions 102 adapted to engage the recess portions 43, 44 to retain the connection member in the slot.
  • FIG. 11 shows a typical construction of a T-junction using the connection members 100 and the interconnect member 110.
  • the structural members according the present invention may be constructed in a number of different ways.
  • the Figure 1 construction has the outer shell and the arcuate member constructed separately, the arcuate member then being inserted into the outer shell on construction.
  • the members may be formed in a single stage by moulding or pultruding them from fibre reinforced composite materials.
  • Figure 13 Another method of construction is shown in Figure 13 where the structural member is formed in two halves 130, 131 which are then either bonded together directly or, as shown in Figure 13 bonded via a bonding member 132.
  • the bonding member having a web portion 135 against which the edges of the halves of the structural member 130, 131 are abutted, and flange members 133 which also abut against the inside 136 and outside 134 surfaces of the halves 130, 131 of the structural member.
  • the two halves and the bonding members are then bonded together at these contact surfaces to form the structural member.
  • FIG 14 shows a multicellular structural member comprising two arcuate members 64 within a single outer member although it is envisaged that three or more arcuate members may be used.
  • the arcuate members may be separated by rib members 61 as shown in figure 6. Again the spaces 62 may be filled with a foam material and/or have rib members 21 to distribute the load.
