Definitions
- This invention relates to a fixing device for use in clamping together two overlapping plates, such as the bottom flange plate of an upper I-section beam and the top flange plate of a lower I-section beam extending under and supported from the upper beam.
- LINDAPTER fixings have been used for many years for joining together flanged metal beams, and for other uses, and remain widely used by customers for many different fixing applications.
- An example of existing use of LINDAPTER fixings is shown in Figure 1 of the accompanying drawings, to which reference will now be made.
- the fasteners are designated by reference 54, and each comprises bolt 55, nut 56 and a pair of opposed gripping saddles 57 which have ribbed gripping noses 58 to engage respective flange edges.
- a feature of use of the fixings 54 to join together two overlapping flanged beams is the need for a separation plate 59 to be provided, sized according to the dimensions of the flanges of the overlapping beams, and which is positioned between the bottom flange 52 of the upper beam 50 and the top flange 53 of the lower beam 51.
- the specially sized plate 59 also requires formation of drilled holes 60 at corner locations to suit the particular combination of flange plates to be joined together.
- This separation plate is an essential component of the known fixing system, in conjunction with suitable LINDAPTER type threaded fasteners.
- a need is now becoming recognised for a fixing device which can be used to clamp together two overlapping plates, and more particularly overlapping flange plates of one beam overlying another beam, and which is readily adjustable for use with different widths of flange plate, so as to provide economies in labour costs of assembly of overlapping beams on site.
- This need is being recognised particularly in factories into which conveyor systems are to be installed e.g. car assembly lines, where there are many locations at which different sized support beams intersect and require to be clamped together at such intersections.
- a fixing device for clamping together first and second overlapping plates having respective first and second pairs of opposed connecting edges which intersect at four corner regions, said fixing device being operative to clamp the second plate to said connecting edges of the first plate and to clamp the first plate to said connecting edges of the second plate, and said fixing device comprising: a set of four elongate clamping plates each positionable along a respective one of said connecting edges of one of said plates and of a length to project axially beyond the opposed connecting edges of the other of said plates whereby each end of each clamping plate is positionable over a respective one of said corner regions; slots formed through each clamping plate and extending generally parallel to the axis thereof so as to overlie said corner region; and, a set of four threaded fasteners each being capable of being taken through a slot of one clamping plate at one corner region and through a slot of an underlying clamping plate at the same corner region, each fastener being adjustable along the length of the respective slot until it reaches a required position in the respective corner region and
- the invention therefore provides a fixing device which is adjustable to suit different widths of overlapping plates (width being measured between opposed connecting edges), and which therefore can readily be operated on site to meet differing requirements.
- the fixing device of the invention is therefore "universal" in the sense that a common design can be utilised with a range of plate widths.
- a particularly preferred arrangement of overlapping plates to be clamped together by a fixing device of the invention comprises an overlapping arrangement of flanged beams, such as I-beams.
- the four corner regions at which the threaded fasteners are located will be at the corners of a rectangular area.
- the beams it is not essential to the invention for the beams to intersect at right angles to each other, and they may be arranged skewed, in which case the area of overlap will be a parallelogram.
- the fixing device of the invention is just as capable of clamping together two overlapping plates in such an arrangement.
- each threaded fastener will be adjusted along the length of a respective slot until the fastener projects downwardly closely adjacent to an underlying connecting edge, and is then tightened up.
- the threaded fasteners preferably include “washers” which fit around the threaded shanks of the fasteners, and each of which can make gripping ' engagement with gripping portions along the slots of the clamping plates.
- a fixing device according to the invention is particularly suitable for joining together the flanges of beams having flange thicknesses which are approximately constant throughout their width, but this is not essential to the invention.
- a fixing device according to the invention can be used also to clamp together flanged I-beams of tapering flange thicknesses as used particularly on the US market, provided that the threaded fasteners are located closely adjacent to each corner region, and with sufficient overlap of the clamping faces of the clamping plates which engage the flange edges, so that a rigid and shake proof clamped assembly can be obtained.
- each clamping plate in the set of clamping plates for each fixing device of the invention may be of identical design. However, this is not essential to the invention, provided that each clamping plate fulfils the requirements of the fixing device of the invention as defined above.
- Figure 2 is a diagrammatic illustration of two overlapping plates which can be coupled together by a fixing device according to the invention
- Figure 3 is a side view showing part of a preferred embodiment of fixing device according to the invention, being used to join together the flange plates of two overlying I- section beams;
- Figure 4 is a plan view of one of a set of four coupling plates forming part of the fixing device of the invention.
- Figures 5a to 5c are, respectively, plan, side and end detail views of a washer type clamping element for use with each of a set of four threaded fasteners also forming part of the fixing device of the invention.
- Figure 6 is a view, similar to Figure 3, of a modified embodiment of the invention.
- FIG. 2 of the drawings this is a schematic illustration of first and second overlapping plates which can be clamped together by a fixing device according to the invention, and these plates may comprise, for example, a bottom flange of an upper I-section beam, and a top flange of a lower I-section beam which overlap at a perpendicular point of intersection between them.
- first and second overlapping plates are designated by references 10 and 11 , and first plate 10 has a first pair of opposed connecting edges 12, and second plate 11 has opposed connecting edges 13.
- the connecting edges 12 and 13 intersect at right angles at four corner regions 14, and it is at these corner regions, as will be described in more detail below, at which threaded fasteners are positioned in order to clamp together the overlapping plates.
- the embodiment of fixing device comprises a set of four elongate clamping plates which will be described in more detail below with reference to Figure 3, and each clamping plate can be positioned along a respective one of the connecting edges of one of the plates e.g. along connecting edge 12 of first plate 10, and will be of a length sufficient to project axially beyond the opposed connecting edges (13) of the second plate 11, whereby each projecting end of each clamping plate is positionable over a respective one of the corner regions 14.
- FIG. 3 of the drawings shows a top flange plate 11a of a lower I-section beam 15, and a bottom flange plate 10a of an upper I-section beam 16, of which only part of the web 17 is shown.
- the web 17 of upper beam 16 extends perpendicular to the web of lower beam 15.
- flange plate 10a rests directly on the upper surface of flange 11a.
- Flange plates 10a and 11a are examples of the overlapping plates 10 and 11 shown schematically in Figure 1 ) .
- a set of four elongate clamping plates is provided, three of which are shown in Figure 3, and each being designated generally by reference 18.
- Each clamping plate 18 is positioned along a respective one of the connecting edges, as described above in connection with the pairs of edges 12 and 13 shown in Figure 2, and the two clamping plates 18 shown below flange plate 11a extend generally parallel to the axis of the beam 15, whereas the upper clamping plate shown above the flange plate 11a in fact sits flush on the upper surface of flange plate 11a, and extends parallel to the axis of upper beam 16.
- each of the two upper clamping plates 18 engages over the upper surface of the connecting edge of top flange plate 10a, in generally similar manner to the way in which nose portions 18a of the two lower clamping plates 18 press against the underside of bottom flange plate 11a.
- Figure 4 is a plan view of a clamping plate 18, and nose portion 18a is illustrated, which comprises the “toe”, and reference 18b defines the “heel”, which will engage the surface of the adjacent clamping plate proper.
- each clamping plate 18 has a pair of axially extending slots 19, and which are of sufficient length to allow adjustment along the length of the slots to suit the particular width of underlying flange plate.
- the slots 19 will extend sufficiently far so as to overlie the corner regions 14.
- a set of four threaded fasteners is provided, designated generally by reference 20, and each being capable of being taken through slot in one of the two upper clamping plate 18 shown in Figure 2, at one corner region 14, and through a slot in the underlying clamping plate at the same corner region.
- Each fastener 20 will be adjusted along the length of its slot 19 until it is located beyond the connecting edge of the underlying flange plate, and then is tightened in order to clamp the two clamping plates together. Accordingly, a respective threaded fastener 20 ⁇ can be adjusted.until it is positioned at a respective one of the four corner regions 14, and is then tightened in order to clamp together overlapping flange plates 10a and 11a via the set of four clamping plates as a rigid assembly.
- the beams extend perpendicular to each other, but it will be readily appreciated that the fixing device of the invention can be used readily in order to couple together a skewed junction of overlying beams.
- the lower radiused washer 22a shown in Figure 3 is able to allow the associated clamping plate 18 to rock until nose 18a engages the underside of the flange 11a and the heel 18b engages the other clamping plate, while still maintaining the shank of the fastener vertical, and being restrained from moving along the slot 19 by the grooved surface 21.
- the clamping plate can readily be adjusted to suit different plate (flange) thicknesses.
- each clamping plate 18 in the form of an extra protrusion or leg to prevent the clamping plates sliding out of engagement with each other when they are being used at the extremity of their adjustment.
- the tail portion 18b of each clamping plate 18 has an additional leg or protrusion 18c
- Figure 6b shows the clamping plates 18 at the limit of their adjustment, and in which leg 18c of one of the underlying clamping plates is closely adjacent to leg 18c of the overlying and perpendicularly extending clamping plate.
- Figure 6 shows application of markings 23 which assist in installation, with appropriate marking being determined by experiment for any particular combination of flange plates to be joined together.
- a central marking 24 is also provided.
