BUILDING SHEET POSITIONER

Abstract

A separator for insertion between building construction sheets for externally cladding buildings that has a handle part securable to an existing sheet and a spacer bar that overlies the edge of an existing sheet in order to project into the path of an incoming sheet and space it from the existing sheet. The handle and spacer bar are made of metal. Four separators are required for insertion at two adjacent edges of an incoming building sheet.

Claims

1. A building sheet positioner comprising: a handle with a planar surface; and a linear spacer projecting from the planar surface in order to overlie an edge of a sheet, and lying parallel to the planar surface, wherein the spacer: presents a surface to an incoming building sheet that is parallel to the sheet edge with which it is already in contact; and lies closer to a handle end of the handle.

2. The building sheet positioner as claimed in claim 1, wherein the handle is linear and the spacer lies transversely to the handle, a portion of the handle between the handle end and the spacer acting as a retaining surface for the incoming next adjacent sheet.

3. The building sheet positioner as claimed in claim 1, wherein the spacer lies at 90 degrees to the handle.

4. The building sheet positioner as claimed in claim 1, wherein the handle has at least one bore for reception of a fastener to attach the positioner to the underlying sheet.

5. (canceled)

6. The building sheet positioner as claimed in claim 1, wherein the handle portion between the handle end and the spacer is inclined to the planar surface.

7. The building sheet positioner as claimed in claim 1, wherein the spacer is a rod of circular cross-section.

8. The building sheet positioner as claimed in claim 1, wherein the spacer has a bore for the reception of a fastener to attach the positioner to a support surface.

9. The building sheet positioner as claimed in claim 1, wherein the spacer is attached to the planar surface by welding.

10. The building sheet positioner as claimed in claim 1, wherein the planar surface extends from one end of the positioner to the spacer, the surface between the spacer and the opposite handle end of the handle being inclined to the planar surface.

11. The building sheet positioner as claimed in claim 1, wherein the positioner is made from a flat blank of sheet metal 1.5-2.0 mm thick.

12. A method of fixing building sheets to a support surface such that each sheet is separated from an adjacent sheet by a uniform gap, the method comprising: fixing a first building sheet to the support surface; applying a pair of sheet positioners, made according to the positioner defined in claim 1, to an edge of the fixed sheet to define a gap causing the sheet positioner to project into the gap; placing a second sheet in contact with the support surface so that one edge of the second sheet contacts both sheet positioners to produce a parallel gap; fixing the second sheet to the support surface; and removing the pair of sheet positioners.

13. Walls and ceilings covered by building sheets attached by the method as claimed in claim 12.

14. The building sheet positioner of claim 1, wherein the surface between the spacer and the handle end of the positioner is inclined away from the outer surface of the mounted sheet.

15. The building sheet positioner of claim 1, wherein the handle portion is inclined to the planar surface to facilitate the insertion of the incoming adjacent sheet behind the handle portion during installation.

16. The building sheet positioner of claim 2, wherein the spacer lies at 90 degrees to the handle.

17. The building sheet positioner of claim 2, wherein the handle has at least one bore for reception of a fastener to attach the positioner to the underlying sheet.

18. The building sheet positioner of claim 2, wherein the handle portion between the handle end and the spacer is inclined to the planar surface.

19. The building sheet positioner of claim 2, wherein the spacer is a rod of circular cross-section.

20. The building sheet positioner of claim 2, wherein the spacer has a bore for receiving a fastener to attach the positioner to a support surface.

21. The building sheet positioner of claim 2, wherein the spacer is attached to the planar surface by welding.

[0025] FIG. 9 is an end view of the positioner in FIG. 8 showing the fastener bore.

DETAILED DESCRIPTION

[0026] Referring to FIGS. 1, 2 and 7, the wall 2 in the upright concrete slab wall of a building with three sheets 4, 6, 8 already affixed with 8 mm gaps 10 separating each sheet from the next adjacent sheet.

[0027] In order to position the next sheet 36, pairs of positioners 14 are attached in the position shown in FIG. 1 and attached to the sheets 4, 8 by screws 30.

[0028] Referring now to FIGS. 2, 3 and 4, the positioner 14 is made from a 2525147 mm length of steel square tube 2525 mm. The faces of the tubes are planar and lie at 90 degrees to each other. One planar face 16 has an 808 mm threaded rod 18 welded at 90 degrees to the tube axis 20. A cutout 22 gives access to the tube wall 24 acting as the planar face. The tube wall 24 has a pair of bores 28 to take fixing screws 30 (one shown).

[0029] The purpose of the cutout is to allow the operator to insert the screw 30 into the bore using an electric portable screwdriver. This fastens the positioner in the place shown in FIG. 2. The 8 mm rod 18 is threaded and extends 80 mm along the top edge 32 of sheet 6. The top end 34 of the device is inclined in order to assist the reception and slide-in of entering sheet 36.

[0030] When all four positioners have been screwed in place in the positions shown in FIG. 1, sheet 36 is manhandled into the gap 38 so that the two entering edges lie spaced from sheets 6 and 8 by 8 mm, the thickness of spacer rod 18 as shown in FIG. 7. The sheets are attached to the wall 2 by fasteners.

[0031] The eight retaining screws 30 are then unscrewed and the positioner 14 is pulled from between the sheets to be used for the next sheet placement. The screw holes are filled and the fastener sites are covered by finishing operations that are subsequently carried out when the wall is fully covered.

[0032] When the wall 2 is replaced by a ceiling, the sheets attach to joists or battens but the technique is the same.

[0033] In FIG. 8, the positioner is made from a blank, which is laser cut from 1.8-2.0 mm sheet steel. A transverse slot is cut in the area that is to mount the spacer and an acute U-section cutout is removed from the handle end 40 closest to the spacer. This allows that end to be folded to close the gap resulting in a change to the planar surface. The minor part 42 is inclined to the major part 44. Weld 46 hides the transverse slot.

[0034] In FIG. 9, bore 48 passes through the spacer 18 and the planar surface 44 for the reception of a fastener to attach the positioner 14 to the support surface 2.

[0035] It is to be understood that the word comprising as used throughout the specification is to be interpreted in its inclusive form, i.e., use of the word comprising does not exclude the addition of other elements.

[0036] It is to be understood that various modifications of and/or additions to the disclosure can be made without departing from the basic nature of the invention. These modifications and/or additions are, therefore, considered to fall within the scope of the invention.
