Definitions
- This invention relates to a structural support beam manufactured from a composite of materials, and in particular, but not exclusively, to a composite of timber in various forms with an infill of material that provides both added structural support and thermal/sound insulation, for use in the building and construction industry.
- Support beams of the form of Laminate Veneer Lumber (LVL) , Parallam products, Glulam products, I-joists and Box Beams, are known. These different support beams offer different structural properties and are used in different designs for different applications. For example, Parallam products have a high stiffness and strength compared to the other above-mentioned beams, but are heavier, more abrasive to saw and drill, require connection be made to adjacent beams with metal plates and bolts or dowels rather than nails, and are relatively costly; LVL products provide strength and consistent performance, are easy to work with, can be cut and nailed on site, resist shrinkage, warping, splitting and checking, but are relatively costly.

- Box beams are moderately lightweight, can be handled easily, allow a higher load capacity than comparable sized timber, resist shrinkage, warping and checking and are more efficient than solid timber for large spans and loads.

- Fig. 13 shows how some of the embodiments may be fitted with metal plates to improve their structural characteristics .
- the integrity of the flanges affects the structural qualities of a support beam.
- the connection of the outer support webs to the flanges is an important area in terms of structural integrity.
- the absence of grooves, recesses and cut out portions in otherwise rectangular shaped flanges offers several advantages.
- rectangular it is meant that the flanges are of a regular four-sided rectangular or square shape without any formations such as grooves recesses or cut-out portions to accommodate the outer support webs.
- Rectangular flanges offer several advantages as follows: (i) Ease of Construction - the simplicity of the design avoids the need for expensive grooving and close tolerances; (ii) Strength and Stiffness - the presence of grooves or recesses within the flanges creates areas of weakness and hence reduces the bending and longitudinal shear strength capacity of the structural beam. For a set beam depth (often governing the design and detailing criteria) , a box shaped design such as that shown in Fig.
- the support beams of the present invention incorporate both structural and insulation qualities into a single member during manufacture thus achieving higher quality, more accurate thermal and/or sound efficiency and an increased level of structural support.
- the structural beams of the present invention can also be produced in varying sizes and thickness depending on the particular application and insulation/structural requirements.
- the material 110-1010 not only provides thermal and/or sound insulation, but also provides increased structural properties as demonstrated by Fig. 14, the results of which are described below.
- (A) and (B) which are the support beams of Figs. 2 and 1, i.e. with and without the infill of material 110 respectively; (C) and (D) which are the support beam of Fig. 9 and a corresponding support beam without an infill of material respectively; (E) and (F) which are the support beams of Fig. 5a and a corresponding support beam without an infill of material respectively; and (G) and (H) which are the support beams of Fig. 8 and a corresponding support beam without an infill of material respectively.
- corresponding flanges were cut from Whitewood grade C16 timber.
- the corresponding outer support webs were cut from 11mm thick OSB grade 3 panels and the infill material was 95mm thick expanded polystyrene (EPS) . All contact surfaces were glued together, and where appropriate, were screwed using 2x8 woodscrews .
- EPS expanded polystyrene
- the infill material adds very little overall weight to each support beam, yet it provides a significantly increased ultimate load capacity. Furthermore, the requirement for I-beams and box beams to have web stiffeners at areas prone to localised buckling may be dispensed with due to the increased ultimate load capacity of the support beams having the infill of material .
- the results shown in Fig. 14 show that the support beams having the infill of material (A, C, E, G) can carry the same load for an increased deflection/displacement, i.e. they have enhanced ductility qualities.
- supports beams (C) and (D) are worthy of further comment.
- the infill of material in support beam (C) exhibits an interesting quality in that it appears to affect the failure mode of the support beam.
- support beam (D) appears to fail suddenly at a displacement of approximately 4mm
- support beam (C) appears to initially fail at a displacement of approximately 5mm yet can still hold the load applied for a further 4mm of displacement. This shows the level of enhanced ductility provided by the infill material of support beam (C) .
- Fig. 15 shows a qualitative comparison of the structural support beams of the present invention with known designs.
- the structural support beams of the present invention may be used in any building and construction projects.
- the support beams may be in the form of I-beams, double I-beams, box-beams, boxed I-beams or boxed double I-beams.
- the infill material 110-1010 may be pre-fabricated, in which case, the respective outer support webs and flanges of a support frame may be bonded directly to the pre-fabricated material 110-1010.
- the infill material may be formed from either open cell, closed cell or a mixture of open and closed cell foam materials.
- the infill material may be formed from a wood-based material or any other suitable material providing the desired structural and/or thermal/sound insulating properties.
- the material 10-1010 may be injected into a volume defined by a support frame of outer support webs and flanges, wherein the material expands to fill the volume.
- the respective contact surface of the support frame may have bonding means to assist on securing and ensuring a close contact with the infill of material 10-1010 to the support frame.
