Abstract

A conical core is fixed to shuttering and removed with the shuttering after casting to leave a cavity for electrical outlets. Electrical conduits A to be embedded in the concrete are connected together by an earth link M which includes a screw thread which provides a temporary connection for the conical core. Bracket J may be screwed into the earth link after removal of the core for connection of light or other electrical fittings. <IMAGE>

Description

SPECIFICATION Multiconduit conical spacemaker device incorporating earth connector rod, connecting collar, light fitting bracket or bracket for lid and also temporary locating screw for conical device The object of the invention is to provide a means of forming a permanent conical space within concrete slabs and walls through which can be routed and terminated electrical conduits linked together by means of an earth link connecting rod which includes a temporary fixing screw for locating the reuseable space forming conical device. And conduits to either shutters of formwork during concrete or similar material curing porcess employed in the construction of walls or slabs.
On removing the temporary screw, shutters and also the reuseable conical device, the conduits and earth link rod remain within the formed space and by means of a bracket having one end screwed in to the connecting collar on the earth link rod direct connection can be made with proprietory light fittings and electrical apparatus using the opposite end of the bracket.
Alternatively, the created space complete with conduits and earth link rod can be used to form junction boxes by use of a bracket incorporating a lid which fits within the rebated external rim of the created space and can be secured to the concrete with screws. In both instances the pulling of electrical cables and wires can be effected prior to fixing of either of the two alternative brackets and where appropriate connection of cables made to the light fittings or other electrical apparatus terminals. Special adaptors are available to enable location of conduits within the diametric holes in the rear face of the conical device where the sizes of any such proprietory conduits do not match the standard size of conical device.
Where the standard four conduit conical device is not suitable for application then conical devices suitable for use with either two or three number conduits and employing the same principles and concepts incorporated in this specification and appended drawings, can be employed.
Features of the method of performing this invention are further outlined on the appended drawing figure numbers 1 to 4 inclusive and the following detailed description in which: Figure No. 1 is a diagrammatic cross sectional view showing the conical device (B) temporarily located to formwork or shutter (D) by means of a screw (E) shown in hatched lines, which is connected to the earth link rod (G) by a connecting collar (H) which is connected to conduit sections (A) by means of multi-conduit connector (M) through which the earth link rod is screwed and as appropriate brazed in position.
Also the multi-conduit connector is separately welded or brazed to the conduit sections on site or prefabricated off site.
Proprietory screwed or compression elbows (F) are fitted to the conduits to afford any required change in direction of routed conduits.
Shown in full lines is the lid and fixing rod (L) which fits into the rebated rim of the conical space formed in the concrete (K). The lid can be fixed by means of screws to the concrete aided by the indentations formed by the blips (C) on the rear of the planar front face of the conical device (B).
Also shown in hatched lines is the alternative connecting bracket (J) for connection to light fittings and other electrical apparatus. The connecting bracket can be adjusted in length to suit support and placing of the light fitting or electrical apparatus to the siab or wall, this being afforded by the tolerance available within the connecting collar (H).
Through the bracket (J) can be routed the electrical cables for connection to light fitting terminals. Also the bracket (J) incorporates holes for direct fixing to the light fitting where necessary. The bracket (J) can be increased in diameter as necessary to form a lid similar to lid (L).
Figure No. 2 is a part cross section (of conduits (A)) rear face view of conical device (B) showing proprietory elbows (F).
Figure No. 3 is a diagrammatic cross sectional view similar to Figure No. 1 but showing the alternative use of conduit lengths (A) incorporating pulled bends (F) all of which can be fitted to the conical device on site.
The inserted conduits are earth link connected to each other by means of a strap system (M) incorporating self tapping earthing screws (N) which can as necessary be brazed or welded in position. All other items relating to the invention are identical to those in the description and drawing of Figure No. 1, except that the light fitting bracket (J) is now shown in boid lines and the conical space lid (L) is shown in hatched lines, this to afford further appreciation of the various applications of this invention.
Figure No. 4 is a part cross sectional end view showing the pulled bends (F) being part of the conduits (A) and also the strap system (M) with the self tapping earthing screws (N).
Claims
1. What I claim is a method of forming a "junction", "draw" or connector box system within concrete structures utilising a reuseable conical spacemaker device.
2. A method, further to claim 1 above of providing location and termination of conduits within concrete or similar material walls or slabs, for future connection to light fittings and other electrical apparatus.
3. A method, as Claim 1 above, of maintaining an earth link between conduits and light fittings or electrical apparatus on removal of the temporary conical device and locating screw.
4. A method, as claim 1 above, of affording access to formed conical space for pull, store, and connection of cables or wires to light fitting
