  • the top and bottom walls 2 and 3 are provided with short, outwardly extending, reinforcing flanges 5 while the side walls 4 intermediate their height are shown as having short projections or nibs 6.
  • This aluminum beam constitutes a load bearing beam capable of sustaining substantial loads.
  • a beam is not adapted in itself for incorporation into an interlocking thermoplastic building system, both from the standpoint that it lacks the necessary interlocking connections and as well the aesthetic appearance of the thermoplastic structural members with which it is intended to be used.
  • thermoplastic sleeve 7 adapted to receive and encase the aluminum box beam 1 to convert the combination into an interlocking structure as well as adding structural strength as hereinafter more fully described.
  • the sleeve 7 is preferably formed of a reinformed thermoplastic inner layer or core 8 and a co-extruded outer skin designated in dotted lines at 9.
  • the core 8 is preferably extruded from a thermoplastic material reinformed in such a manner that the reinforced thermoplastic provides strength and expansion control yet is still flowable through an extrusion dye.
  • the thermoplastic material may be a vinyl chloride, e.g. a polyvinyl chloride (PVC) reinforced with mineral or other fibres or known expansion controlling agents such as calcium carbonate.
  • the reinforcing agent may be very small, short, glass fibres of the order of a few microns in diameter and few millimeters in length in concentrations not greater than, and preferably substantially less than, 35% by weight based upon the combined weight of glass fibres and vinyl chloride resins.
  • the smooth plastic skin may be PVC, rigid PVC, semi-rigid
  • Such an extruded sleeve has its own inherent structural strength by virtue of the reinforced core while the co-extruded thermoplastic skin covers and seals the outer exposed surfaces of the core interlocking with any exposed core fibres and providing a means of imparting impact resistance, smoothness to facilitate sliding interlocking. Further coloring or other agents may be added to the sleeve if desired.
  • the extruded thermoplastic sleeve 7 in itself, forms a structural beam member having its own inherent load bearing capacity.
  • sleeve 7 is provided adjacent to its top and bottom walls 10 and 11 with interlocking groove formations 12 while outwardly thereof towards the top and bottom walls, the width of the sleeve is reduced as at 13.

  • box beam flanges 5 are located in the reduced sleeve end spaces 13 while the nibs 6 of the box beam 1, while adding central thickness to the sidewalls 4, also will limit inward deflection of the side wall 14 of the sleeve 7.
  • Figure 4 shows an alternative form of aluminum box beam 15 which may be used in place of the beam 1 for somewhat lighter loads.
  • the top and bottom walls 16 and 17 are shown as having the same thickness as the sidewalls 18 while the outwardly projecting flanges 19 at the top and bottom walls 16 and 17 are shown thickened at the end 20.
  • Beam 15 is also shown as having central projections or nibs 21.
  • thermoplastic sleeve 7 By the provision of the thermoplastic sleeve 7, the box beam 1 or 15 when received within the sleeve, are converted into what appears to be a thermoplastic building structure incorporating the means by way of the locking grooves 12 for slidingly interlocking with other mating thermoplastic structural members.
  • Such a composite beam as shown in Figure 3 provides a beam of requisite strength, for example, for bearing the roof load of a building structure with the beam being adapted to span between supporting wall members.
  • Figure 5 is a rear view of a preferred form of beam supporting bracket while Figure 6 is a vertical section taken on a line 6-6 of Figure 5.
  • the bracket generally designated at 22 is in the form of a shelf having sidewalls 23, a bottom wall 24, stepped as at 25 for strength and rear wall panels 26 from which project vertical arms 27 in a staggered relation as shown in Figure 5. These arms are provided with in-turned end flanges 28 and bottom flanges 29 as particularly seen in Figure 11.
  • the bracket 22 is adapted to be mounted against a hollow wall member which, as particularly seen in Figure 11, is a thermoplastic hollow box connector 30 having projecting arms 31 with in-turned fingers 32 adapted to slidably interlock with other wall forming members having locking grooves corresponding to the locking grooves 12 of sleeve 7.
  • box connector 30 will be provided with suitable openings through which the vertical arms 27 can be introduced into the interior of the box connector with the arms 27 being lowered so that notches 33 on the underside thereof as shown in Figure 6 will come to rest on the bottom of slots formed in the box connector (not shown).
  • box connectors are adapted to be filled with concrete or the like to give structural rigidity thereto to provide a permanent wall structure. It will be understood that when concrete is poured into and fills the box connector 30, it will embed the flanged arms 27 anchoring same in position with the flanges 28 and 29 resisting displacement in two right angular directions.
  • the composite beam in this case formed by the sleeve 7 of Figure 2, and the aluminum box beam 15 of Figure 4 is provided with an extruded thermoplastic hollow cap generally designated at 34 which has locking fingers 35 interlocked with the composite beam grooves 12.
  • This cap 34 which does not form part of the present invention, carries roof supporting surfaces 36 and is provided with a roof holding clip 37.
  • the openings required for introducing the flanged arms 27 of the bracket 22 will be suitably taped to prevent concrete from flowing into the shelf formation of the bracket.
  • FIG. 7 illustrates a clip for use with the bearing bracket to guard against lifting of a roof carried by the cap 34 under very high winds.
  • This clip designated at 38 has a plate-like body 39 having a reduced portion 40 which is adapted to span between the bracket arms 27 and is provided with lateral extensions 41, one to engage under the upper arm 27 projecting from one of the rear wall panels 26 and the other to engage under the upper arm extending from the other at rear wall panel 26.
