Definitions
- the present invention relates broadly to building construction and particularly to structural couplings for buildings formed from interconnected pultruded profiles.
- the invention of pultrusion bestowed the benefits of mass production on to composite manufacture in a different way.
- the fibre volume fraction is most advantageous, which has the beneficial effects of enhancing stiffness and reducing thermal movement.
- stiff, dimensionally stable components made of pultruded GRP an innately thermally resistant material
- GRP an innately thermally resistant material
- An object of the present invention is to provide an improved technique for use with the StartlinkTM system to increase and enhance the strength and/or stiffness of the pultruded profiles heretofore held together by the snap-fit action referred to above by incorporating means acting to transfer and more equally distribute the loading throughout the coupled profiles when assembled together to form the particular building construction in hand.
- a structural coupling comprising a plurality of pultruded profiles for forming a structural component of a building such as a wall, floor, ceiling, roof and support beam, connecting means between the profiles to hold the profiles together in assembly and dowelling elements incorporated in and/or between the pultruded profiles to stiffen and/or strengthen the coupling in assembly.
- the dowelling means is in the form of pultruded rods of constant cross-section throughout their length.
- Figure 1 and l(a), (b), (c) show in perspective view and exploded detail respectively a series of pultruded wall and floor studs each formed of a pair of pultruded profiles joined back-to-back and incorporating stiffening dowels in accordance with the invention;
- Figure 2 and 2(a) show in perspective view and exploded detail thereof respectively a series of pultruded profiles joined by dowels in accordance with the invention to provide a three-component beam for a building;
- Figure 3 illustrates in perspective view a floor beam formed of a pultruded profile drilled to accept connecting dowels in accordance with the invention to provide the support of the floor of a building;
- Figure 4 shows the construction of a hand rail formed of pultruded partly circular sections strengthened with dowels in accordance with invention.
- Figure 5 shows in exploded and isometric view an arrangement of pultruded profiles for mounting on poltruded support beams using dowels designed in accordance with a further embodiment of the invention.
- Figure 6 shows a pultruded floor panel mounted on support dowels designed in accordance with a further embodiment of the invention.
- the StartlinkTM system as referred to above is a modular building system that uses pultruded profiles to construct a house for example, without using concrete or structural steel above ground.
- StartlinkTM building system comprise a pultruded floor panel 1, see Figure 3, a pultruded universal panel 2, see Figure 1 and complementary pultruded profiles 3, see Figures 1 and 2 having lightweight or hollow cores.
- the universal panel 2 see Fig l(b) has short return legs 4 along each side that hold extruded gaskets 5.
- Pairs of gasketed legs 4 slot into a single recess 6 on either side edge of the connecting profiles 3 to form studs or trusses 7 to make waterproof seals in the walls and the roof of a building being constructed (not shown).
- the sides 8 1 of a channel section 8 engage the recesses 6 by snap fit action to lock the panels 2 and studs 7 in place and links the wall studs or roof trusses together, see also Fig l(c).
- Pultruded beam profiles 9 for the floor of the building shown in Figure 3 have two purposes that are to stiffen the floor panel 1 and when cut in two, to form the upper and lower cords of a roof truss.
- the beam profiles 9 may be bonded to the floor panels 1 to form a floor and provide support for the universal panel 2 to make a ceiling below and it is worthy of note that the floor and universal panels 1, 2 are light enough to be carried by two people.
- Figure 1 shows an assembly of the pultruded profiles 3 in the form of the studs 7 for use in constructing the walls, floors and openings of a building such as a house and incorporating the modification and improvement according to the present invention.
- the studs 7 are made up of two single pultruded profiles 3 of hollow box construction provided with a pair of interengagable leg formations 10, 11 along the outer most corners of their opposed side edges which nestle together in assembly as show in Fig l(a).
- elongated circular hollowed dowels 16 are passed through the box sectioned interior of the profiles 3 as shown to fit within existing pre-drilled holes 17 in the profiles 3 of other similar wall studs 7 forming the structure.
- dowel securing elements 18 are used in the formation of a beam 19 for a building formed of pultruded profiles.
- the profiles 20 forming the beam are channel shaped in section with pre-drillings 21, 22 being provided in their bases to receive the cylindrical dowels 18 passing through pre-drilled holes 23 in a single pultruded profile 3 as shown.
- FIG. 4 there is illustrated the use of hollow dowels 27 according to the invention to rigidise and strengthen a circular hand rail 28 formed of pultruded profiles.
- the pultruded profiles of the hand rail 28 are and provided with means (not shown in detail) for snap fit engagement along their split lengthwise edges with the cylindrical dowel 27 dimensioned to fit within the circumferential opening so formed.
- Cylindrical dowels however are difficult to bond to adjacent flat surfaces and also distribute loads through a contact point instead of spreading the loads over a wider area.
- Polygonal, preferably rectangular, dowels are stiffer and they provide a flat surface for bonding to other flat surfaces. They transfer loads more evenly than point loads from cylindrical dowels to other profiles but rectangular holes to accommodate them are more difficult to manufacture. Rectangular dowels with circular hollow centres can be bonded into or located in larger profiles provided with rectangular hollow interior chambers for example in box structured profiles.
- Cylindrical dowels can then be inserted into the rectangular interior chambers to transfer loads through circular holes drilled in other profiles. Rectangular dowels can also be turned to make the outer profile circular to fit circular holes in other profile sections.
- Cylindrical dowels with rectangular shaped hollow interiors can then be mounted around rectangular dowels of corresponding size to strengthen them and to transfer loads through circular holes drilled in other profiles.
- Components capable of locating dowels as above described can be bonded to other profiled sections to form stronger profiles such as grounds beams.
- the ground beams can then be assembled into a structural rectangle or frame by using a combination of rectangular dowels and cylindrical dowels inserted in circular drillings in the rectangular dowels at each corner of the structural frame.
- dowels from one side of the rectangle are arranged to enter holes drilled in an adjacent side of the rectangle and by opposing the direction of insertion of the dowels the corner joint is mechanically locked together.
- Figure 5 there is shown an assembly of pultruded universal panels 2 as aforedescribed and a profile section 3 forming a connecting stud wall 7, an arrangement of which has been described with reference to Figure 1.
- the universal panels 2 and stud walls 7 are secured to a rectangularly arranged frame of interconnected ground beams 19, as will be explained below.
- the stud profile 3 is of box construction providing lengthwise corner box chambers forming rectangular openings 30 as shown.
- Composite dowel pieces 31 formed of an upper section 32 of rectangular cross-section and a lower section 33 of circular cross-section are provided with the upper section 32 arranged for insertion in the corner box chambers 30 of the stud profile 3.
- the lower sections 33 of the dowel pieces 31 are inserted in circular drillings 34 formed in edge portions 35 of the ground beams 19 which have box section chambers 36 of axial extent and forming rectangular openings at their corners as shown.
- the upper and lower sections 32, 33 of the dowel pieces 31 are provided with circular drillings 37, 38 the axis of which are at 90° to one another.
- dowel shells 37 of rectangular cross-section provided with circular open-ended drillings 38 for receiving cylindrical dowels 39.
- each of the ground beams 19 of the rectangular ground beam frame is offset cut to form a leading end closure section 44 which fits over the end of an adjacent beam of the rectangular frame with a trailing section 45 which abuts the side surface of that adjacent beam in assembly.
- the circular dowels 39 are inserted through circular drillings 47 in the section 44 and the drillings 38 in the box chamber 36 with the drillings 47 in alignment with the drillings 38 in the rectangular dowel shells 37 as shown.
- the cylindrical dowels 39 as previously described are inserted in the drillings 38 in the rectangular dowel shells 37 positioned in the box section corners 36 of the trailing section 45 and the drillings 48 of an adjacent corner beam 19 to mechanically lock the corner joint together.
