Description

A LOCATING AND SUPPORTING APPARATUS
The present invention relates to a locating and supporting apparatus and in particular to a locating and supporting apparatus for use during installation and attachment of roof members.
Roof construction techniques have recently evolved to include roof systems comprising prefabricated modular components which are more easily and quickly assembled into a roof structure. Such modular roof construction also provides greater flexibility in terms of roof layout.
One such example of a modern roof system comprises a preformed component which forms the roof apex, the apex component being a generally triangular cross section beam extending to meet the gable wall on each side of the building. The remaining slope of the roof is then formed by attaching preformed panels to extend from the bottom edge of the triangular beam to the wall plate on both sides of the building extending between the gables.
While the above described system is efficient, the attachment of the side panels to the apex beam can be difficult due to the size and weight of these panels and the impact these factors have on alignment with the apex beam, especially maintaining the upper edge of the roof panels in contact with the lower edge of the apex beam. Installation requires the outer planar surfaces of the apex beam and an attached panel to be accurately aligned prior to attachment. This is currently achieved by placing multiple installation operatives around the panel to direct and control the positioning thereof as the panel is lowered into position from a crane or other such lifting equipment. While this does allow for alignment it is labour intensive, time consuming, and sometimes dangerous, especially given that many panels must be accurately aligned and attached to form a complete roof. The operatives are always fighting against gravity to maintain the upper end face of the panel in a tight abutting relationship with the lower end face of the apex beam.
It is an object of the present invention to obviate or mitigate the problem of accurately locating and supporting roof panel members in position relative to a fixed roof member.
Accordingly, the present invention provides a locating and supporting apparatus for attachment of one roof member to another comprising; a first engagement means locatable on a first roof member and at least one second engagement means locatable on at least one second roof member, the first roof member being a fixed roof member and the at least one second roof member being attachable to the first roof member; the first engagement means and second engagement means being operable so as to urge the second roof member into an installed position relative to the first roof member upon inter-engagement of the first and second engagement means.

The skilled man will appreciate that all preferred or optional features of the invention described with reference to only some aspects or embodiments of the invention may be applied to all aspects of the invention.
It will be appreciated that optional features applicable to one aspect of the invention can be used in any combination, and in any number. Moreover, they can also be used with any of the other aspects of the invention in any combination and in any number. This includes, but is not limited to, the dependent claims from any claim being used as dependent claims for any other claim in the claims of this application.
The invention will now be described with reference to the accompanying drawings which show by way of example only one embodiment of an apparatus in accordance with the invention. In the drawings: Figure 1 is a sectional view through an apex beam and a roof panel to be attached thereto, the apex beam and roof panel having engagement members mounted thereto and being in an uninstalled condition; and Figure 2 is a sectional view through an apex beam and a roof panel to be attached thereto, the apex beam and roof panel having engagement members mounted thereto and being in an installed condition.
In the drawing, there is shown a locating and supporting apparatus indicated generally by the reference numeral 1 for attachment of an apex roof member 2 to a roof panel member 3, the roof panel member 3 being attachable below the apex roof member 2. A first hook member 4 is mounted on the apex roof member 2 and a second hook member 5 is mounted on the roof panel member 3. The first hook member 4 and second hook member 5 being operable so as to urge the roof panel member 3 into installed position relative to the apex roof member 2 upon inter-engagement of the first and second hook members which are adapted to act as a hinge. The inter-engagement of the first and second hook members 4, 5 prevents the roof panel member 3 from moving away from the apex roof member 2 under the force of gravity.
As the panel roof member 3 is often large and of significant weight, it can be supported by the already positioned apex roof member 2 during installation, allowing those installing the panel roof member 3 to more easily manipulate, locate, and attach it to the apex roof member 2.
The apex roof member 2 has a lower end face 6 substantially perpendicular to the inclined roof forming surface 7 of the apex roof member 3. Similarly, the roof panel member 3 has an upper end face 8 substantially perpendicular to the inclined roof forming surface 9 of the roof panel member 3. At least one roof panel member 3 is attachable to the apex roof member 2 so that the lower end face 6 of the apex roof member 2 and the upper end face 8 of the roof panel member 3 are in a firmly abutting relationship with the inclined roof forming surfaces 7, 9 of both being substantially co-planar.
The first hook member 4 provides a fulcrum 10 for the second hook member 5 to pivot about, the fulcrum 10 being located at one end of an engagement flange 11 for engagement with an engagement flange 12 of the second hook member 5. When engaged, the first hook member 4 restricts the movement of the second hook member 5 and resultantly the movement of the roof panel member 3, the restriction in movement being dictated by the hinge action between the first and second hook members 4, 5. The engagement between the first and second hook members 4, 5 permit movement of the roof panel member 3 in a manner causing end face abutment of the apex roof member 2 and the roof panel member 2 to create a continuous inclined roof surface 13. The hinge action formed by the first and second hook members 4, 5 is a result of engagement between the fulcrum 10 formed by at least a portion of the first hook member 4 and the portion 14 of the second hook member 5 being contactable with and rotatable about the fulcrum 10. When engaged, the portion 14 of the second hook member 5 rotatable about the fulcrum 10 is restrained from moving in a downwards direction and horizontally in a direction away from the apex roof member 2. The first hook member 4 has a mounting portion 15 which extends along the main plane of at least part of an outer surface 16 of the apex roof member and is mountable thereto. The engagement flange 11 extends from the mounting portion 15 such that an obtuse angle is formed therebetween and is orientated substantially vertically when the mounting portion 15 is mounted to the apex roof member 2 in situ. The engagement flange 11 of the first hook member 4 is orientated to prevent the engagement flange 12 of the second hook member 5 slipping off during installation.
The first hook member 4 extends along all or part of a lower perimeter 17 of the apex roof member 2, either continuously or intermittently, the perimeter 17 being locatable adjacent to the roof panel member 3 in an installed condition.
The second hook member 5 has a mounting portion 18 which extends along the main plane of at least part of an outer surface 19 of the roof panel member and is mountable thereto. The second hook means is formed by an upwardly depending sloped member 20 extending upwardly from the mounting portion 18 thereof when the main plane 19 of the roof panel member 2 is held in a horizontal orientation. The upwardly depending sloped member 20 is parallel to the engagement flange 11 of the first hook member 4 in an installed position.
The engagement flange 12 of the second hook means extends downwardly from the end of the upwardly depending sloped member 20. The upwardly depending sloped member 20 and the engagement flange have a connecting portion 21 therebetween which forms the portion 14 of the second hook member 5 which receives the fulcrum 10 of the first hook member 4.
In one embodiment of the invention, the first and second hook member 4, 5, are channel sections which extend along all or part the apex roof member 2 and the roof panel member 3, either continuously or intermittently. A plurality of roof panel members 3 are engagable with the apex roof member 2.
In an alternative embodiment the first hook member 4 is a channel formed in the apex roof member 2, the formed channel being fitted with a reinforcing element.
In further alternative embodiments of the invention, the first and second hook members are any members which may form a hinged connection therebetween such as a socket and ball type arrangement or leaf and pin type arrangement.
In use, the roof panel member 3 is lowered towards the apex roof member 2 so that a hook member 4 of the apex roof member 2 engages with a hook member 5 of a roof panel member. Upon continuing to lower the roof panel member 3, the first and second hook members 4, 5 form a hinge causing the roof panel member 3 to rotate into an installed position in which the lower end face 6 of the apex roof member 2 and the upper end face 8 of the roof panel member 3 form an abutting relationship. In the installed position, the outer roof forming surface 9 of the roof panel member 3 and the outer roof forming surface 7 of the apex roof member 2 are co-planar.
During installation, the roof panel member 3 is moved, in an initial generally horizontal state, towards the roof apex member 2 (see figure 1) and the engagement flange 12 of the second hook member 5 is initially placed between engagement flange 11 of the first hook member 4 and the apex roof member 2. The engagement flange 11 of the first hook member 4 at least partially restricts movement of the engagement flange 12 of the second hook member 5 away from the roof apex member. After initial engagement of the engagement flanges 11, 12, the roof panel member 3 is rotated from its initial generally horizontal state into a second state wherein the roof panel member 3 is in planar alignment with apex roof member 2, this planar alignment being guided by the alignment and abutment of the engagement flange 11 of the first hook member 4 and the upwardly depending sloped member 20 of the second hook member 20. Having effected alignment of the roof panel member 3 and apex roof member 2 they can now be secured in position by the use of
suitable fixings.
