Description

<Desc/Clms Page number 1> DEVICE The present invention relates to a fixing device (eg a fixing plate) which may be used in conjunction with a vertical suspension assembly for suspending an ancillary structural component from a building component such as a floor decking. In the formation of floor/ceiling slabs, it is known to use pressed metal decking to form a mould onto which concrete may be poured to form a cast slab. The metal decking serves the dual purpose of a) acting as a mould and b) providing tensile reinforcement to the cast slab. After the concrete sets, a composite decking is formed in the underside of which it is common to form a number of parallel elongate grooves. Such elongate grooves normally have a roof, opposed side walls and a mouth and the spacing apart of the walls increases depthwise (ie away from the mouth), By way of example, the grooves may be essentially dovetail shaped. In order for ancillary structural components such as electrical conduits, pipe runs for sprinkler systems and false ceiling panels to be suspended from the underside of a composite decking, a variety of vertical suspension assemblies may be used. Generally speaking, a conventional vertical suspension assembly is adapted to enter the mouth of the elongate groove and be manipulated or adjusted to an anchored position from which it may be used to suspend an ancillary structural component. Resistance to outward deformation of the walls is borne by the concrete material which is cast onto the metal decking and subject to suitably robust design of the vertical suspension assembly, a
<Desc/Clms Page number 2>
relatively heavy ancillary structural component may be borne reliablv. Where the ancillary structural component is relatively lightweight (eg a ceiling panel), the vertical suspension assembly need not be so robust. Generally speaking, the installation of a conventional vertical suspension assembly into the elongate groove of a decking relies on a series of fairly complicated steps. These may include manipulation or adjustment of a threaded rod, of a threaded fastener and/or of an expandable, collapsible or rotatable main body (eg a head or wedge). Figure 1 (which is described in detail hereinafter) illustrates various conventional vertical suspension assemblies and their steps of installation. A disadvantage common to conventional vertical suspension assemblies is that they are vulnerable to physical disturbance (eg vibration of the decking) which may lead to them becoming unsecure. For example, the installation of many vertical suspension assemblies is concluded by tightening a threaded nut and flat washer against the underside of the main body of the vertical suspension assembly which is within or positioned at the mouth of the elongate groove in the decking. vibrations in the decking may cause the flat washer to he dislocated and/or be subject to rotation which can lessen the integrity of the overall assembly. The present invention seeks to improve the integrity of a vertical suspension assembly by providing a fixing device which may be positioned over the mouth of the elongate groove of a decking in order to impart a stabilising effect to the assembly as a whole.
<Desc/Clms Page number 3>
Thus viewed from one aspect the present invention provides a fixing device (eg a fixing plate) for use in conjunction with a vertical suspension assembly (said vertical suspension assembly being capable of being mounted in an elongate groove of a building component (eg a decking) in order to suspend an ancillary structural component therefrom, wherein the elongate groove has a roof, opposed side walls and a mouth and the spacing apart of at least the part of the opposed side walls adjacent to said mouth increases depthwise, wherein said assembly comprises: a main body insertable through said mouth and adjustable to adopt an anchored mounting position in which the main body engages with at least the part of the opposed side walls adjacent to said mouth; and an elongate member engageable (eg threadedly engageable) with said main body), said fixing device comprising: a substantially flat body having an aperture capable of receiving the elongate member, wherein at least one dimension of the substantially flat body is of greater magnitude than the spacing apart of the opposed side walls at the mouth; and at least two spaced apart legs extending away from a surface of the substantially flat body, whereby the fixing device is positionable over the mouth of the elongate groove such that the substantially flat body may be seated on the exterior face of the building component and the legs may extend into and beyond the mouth of the groove. The fixing device advantageously imparts lateral stability to the vertical suspension assembly by virtue of the fact that the substantially flat body is firmly seated on the exterior face of the building component on either
<Desc/Clms Page number 4>
side of the mouth of the elongate groove. The fixing device advantageously imparts rotational stability to the vertical suspension assembly by virtue of the fact that the legs extend beyond the mouth (ie any tendency to rotate is resisted by the legs impinging on the opposed side walls of the elongate groove). The fixing device of the invention may he used in conjunction with building components having dovetail-shaped or V-shaped elongate grooves. In accordance with the invention, the elongate member (eg a threaded rod or suspension wire) may be used to attach directly or indirectly the ancillary structural component. The substantially flat body may conveniently be substantially circular, ovoid, rectangular or square provided that at least one dimension of the substantially flat body is of greater magnitude than the spacing apart of the opposed side walls at the mouth to enable the substantially flat body to be seated on the exterior face of the building component. Preferably the substantially flat body is substantially rectangular with the longest side being of greater magnitude than the spacing apart of the opposed side walls at the mouth. Preferably the substantially flat body is substantially square with the sides being of greater magnitude than the spacing apart of the opposed side walls at the mouth. Preferably one or more edges of the substantially flat body are inclined (ie are arranged out of the plane of the substantially flat body). Preferably at least one pair of opposite edges are inclined. Preferably the edges of the
<Desc/Clms Page number 5>
substantially flat plate are inclined to form a continuous skirt at the perimeter of the substantially flat body.
In an embodiment of the fixing device of the invention, the aperture is substantially centrally disposed in the substantially flat body. Preferably the aperture is substantially circular. The aperture may be threaded or non- threaded.
Preferably one or more pairs of legs may be diametrically disposed either side of a circular aperture. The legs may extend perpendicularly or non-perpendicularly (eg angularly) away from the surface of the substantially flat body. Preferably the legs extend divergently away from the surface of the substantially flat body.
Preferably the legs (eg four legs) extend away from a face of the substantially flat body. For example, the legs may take the form of tabs (eg rectangular or square tabs) extending away from the face of the substantially flat (eg square) body. The tabs may extend perpendicularly or angularly away from a face of the substantially flat body.
Preferably each leg extends away from an edge of the substantially flat body (eg two legs extend away from opposite edges of the substantially flat body). The legs may conveniently take the form of tabs (eg trapezoidal tabs) extending away from the edges of the substantially flat (eg rectangular) body. Preferably the tabs extend angularly away from the edges of the substantially flat body. Preferably one corner of each tab is chamfered.
<Desc/Clms Page number 6>
In a preferred embodiment of the invention, the surface of the substantially flat body from which the legs extend is the same as the surface from which the edges are inclined. In a preferred embodiment of the invention, the angle to the plane of the substantially flat body of the legs is the same as or greater than the angle of inclination of the edges. If desired, the seating of the fixing plate against the exterior face of the building component may be improved with a retaining fastener (eg a threaded fastener such as a nut) Viewed from a further aspect the present invention provides a kit of parts comprising: a vertical suspension assembly capable of being mounted in an elongate groove of a building component (eg a decking) in order to suspend an ancillary structural component therefrom, wherein the elongate groove has a roof, opposed side wails and a mouth, wherein the spacing apart of at least the part of the opposed side walls adjacent to said mouth increases depthwise, said assembly comprising: a main body insertable through said mouth and adjustable to adopt an anchored mounting position in which the body engages with at least the part of the opposed side walls adjacent to said mouth; and an elongate member engageable (eg threadedly engageable) with said body; and a fixing device comprising: a substantially flat body having an aperture capable of receiving the elongate member, wherein at least one dimension of the substantially flat body is of greater
<Desc/Clms Page number 7>
magnitude than the spacing apart of the opposed side walls at the mouth; and at least two spaced apart legs extending away from a surface of the substantially flat body, whereby the fixing device is positionable over the mouth of the elongate groove such that the substantially flat body is seated on the exterior face of the building component and the legs extend into and beyond the mouth of the groove. The vertical suspension assembly of the kit of the invention may comprise any of the components of conventional vertical suspension assemblies. For example, the main body may be an adjustable or manipulable head, wedge or nut. The main body may be conveniently rotatable, squeezable or collapsible in order to be inserted into the mouth of the elongate groove to adopt an anchored mounting position in which the main body engages with at least the part of the opposed side walls adjacent to said mouth. For example, the main body may be two-piece (eg a multi-nut, a multi-clip or a collapsible member) or one piece (eg a wedge nut or a V-nut) . Preferably the main body is a wedge nut or V-nut. Preferably the ends of the wedge nut or V-nut are chamfered to permit engagement with the opposed side walls of the elongate groove. Preferably the wedge nut or V-nut comprises a diametrically opposed pair of chamfered corners acting as cams permitting unidirectional rotation in the mouth of the elongate groove. Particularly preferably the wedge nut or V-nut comprises a circular boss to increase the section in the direction of the load to be applied in use. The elongate member may be threaded (eg a threaded rod) or non-threaded (eg a suspension wire).
