Description

AN ARRANGEMENT AND METHOD FOR INSTALLING A MODULAR ROOFING COMPONENT The present invention relates to an arrangement and method for installing a modular roofing component onto a roof of a building. In particular, the present invention relates to an arrangement and method for installing a pitched roof module on a building.

Pitched roofs are traditionally manufactured from roof trusses comprising wooden frames which are set upon the brick or timber-framed walls of a building, usually on a wall plate, the wall plate defining the upper surface of the uppermost portion of the wall. A layer of waterproofing material is laid over the trusses and battens are mounted thereupon which in turn supports tiles, slates or an alternative outer roof covering. Conventional trusses that provide a structural support to sloped roofs in buildings are well known. Trusses are of a substantially triangular shape and when in use comprise a horizontal member, known as a tie beam, which defines the ceiling of the uppermost storey of a building and two angled members (rafters) which define the pitched sides of the roof.

Conventional trusses are typically pre-fabricated off-site and subsequently transported to the required location and installed one at a time using cranes. A disadvantage of this pre-fabrication of a truss is that the truss is bulky as it is designed to extend for the width of a building and is therefore difficult to store, transport and install. A further major disadvantage with traditional roof truss assemblies is the health and safety risk they present to installers. The trusses must be individually installed on the roof and the installers must walk through these trusses which have webs along the width resulting in it being a difficult and cumbersome working environment especially at heights.

In recent times a greater emphasis has been placed on prefabricated modular roofs that are delivered to the site on lorries. This provides a reduction of health and safety risks for workers building traditional roofs over extended periods at heights, and in some cases with minimal health and safety equipment. Such modules typically consist of a complete portion of the roof of a building, such as one entire finished pitch of a dual-pitched roof.

Where the module is being inserted between two opposing gable walls, it is imperative that the module does not knock into these walls, potentially causing damage to the walls or the module. The module should be installed relative to the wall plate, so that a uniform portion of the eaves rest on top of each gable wall. If the module is not correctly aligned with the walls then the building will appear asymmetrical, with differing amounts of the eaves overhanging the top of the gable at each side of the building.

A problem with prefabricated modular roofing components is the installation of quite a large and cumbersome component using heavy-lifting gear from the lorry and with the installer being generally located on the ground controlling the lifting gear. The problem arises at the final stages of the installation of the modular roofing component as the entire component is being lowered into its final position. It can be difficult for the person controlling the crane to exactly determine the location of the modular roofing component relative to the walls. The component visually obscures much of the building, including the wall plate, when it is being lowered. Several ground workers and the crane operator guide the component into position with guide ropes, and other workers must observe the position of the component relative to the walls and command fine adjustments of the module position as it is lowered onto the building. The installation process is time consuming, labour intensive and prone to human error. Additionally, uncontrolled, erratic movements of the lifting crane can cause the module to swing into the gable walls, potentially causing damage to the building. There is therefore a requirement for an apparatus that improves the installation process and for enhancements to the method of installation.

It is an object of the present invention to mitigate the above-mentioned disadvantages regarding installation of a modular roofing component.

It is a further objective of the present invention to provide an arrangement to aid in installation of a modular roofing component.

According to a first aspect of the invention there is provided an arrangement for installing a modular roofing component, the arrangement comprising a guide means for guiding a modular roofing component into a final position during installation of the modular roofing component on a building.

Advantageously, the guide means mitigates the requirement for human guidance of the modular roofing component onto the building thereby mitigating the risk of human error.

During installation of a modular roofing component, the view of the building and the wall plate can be obscured by the modular roofing component and it is difficult for the installer to view the position of the modular roofing component relative to the building. The guide means provides an assurance to the installer that the modular roofing component is correctly aligned relative to the building as it is installed.

Ideally, the guide means is adapted to be mounted to a surface.

Preferably, the guide means operates in tandem with any lifting means or guide ropes that are also being used to guide the modular roofing component into position on a building.

Ideally, the guide means is operable to align a modular roofing component relative to a wall plate whilst the modular roofing component is moved towards the wall plate.

Preferably, in use, the guide means defines and predetermines the final position of a modular roofing component in a building relative to the gables.

Preferably, the guide means comprises physical guide means such that the guide means physically guides the modular roofing component into its final position.

Advantageously, in contrast to a visual guide means such as markers on the existing building structure indicating where the modular roofing component should be located in its final position, a physical guide means does not require constant checking and readjusting/realignment during installation of the modular roofing component. Further advantageously, the physical guide means remain operable even when obscured from view, e.g., by the modular roofing component as it is lowered into position on the building.

Additionally the guide means may also comprise visual guide means or other guidance indicators to assist in guidance of the modular roofing component into its final position.

Preferably, the guide means is operable to guide a modular roofing component having a fascia into position such that the horizontal midpoint of the fascia is located substantially equidistant from opposing gable/end walls and/or centrally located along a wall plate.

Advantageously, when the modular roofing component is in its final position the appearance of the gable/end wall eaves is symmetrical about the building.

Ideally, the guide means is mountable, most preferably releasably mountable, on a surface.

Ideally, the one or more guide members are shaped such that when the one or more guide members are fixed to a surface and when the modular roofing component is lowered onto the one or more guide members, the one or more guide members displace, most preferably horizontally displace, the modular roofing component.

Ideally, the one or more guide members comprise a sloped portion defining a sloped surface in use.

Advantageously, where the guide member is mounted on a building and where the modular roofing component abuts the sloped surface whilst it is lowered onto the sloped portion, the modular roofing component will be moved along the slope and is thereby displaced by the guide member. Alternatively, if the guide member is mounted on the modular roofing component, and where the modular roofing component abuts into an adjacent building to which it is being lowered into position such that the guide member engages the building, the sloped surface slides the modular roofing component away from the building.

Ideally, the one or more guide members are mountable on a wall plate at an area proximal to a gable/end wall.

Ideally, the distance between one guide member and the gable/end wall proximal to said guide member is substantially the same as the distance between the other guide member and its proximal gable/end wall.

Advantageously, as the guide members are each equidistant from their respective proximal gable/end walls, the gable-wall-facing surfaces of the modular roofing component will also each be equidistant from the opposing gable walls upon being guided into position by the guide means.

Preferably, the one or more guide members comprise a mounting portion adapted to be mounted to a surface such as a wall plate, gable/end wall or modular roofing component.

Ideally, the mounting portion comprises a fixing means and/or aperture(s) for receiving fixing means such as bolts for mounting the guide member to a surface.

Advantageously, a worker can mount the guide member to a wall plate, gable/end wall or modular roofing component via the fixing means.

Advantageously, the angled relationship between the mounting portion and the sloped portion provides the slope which guides the modular roofing component as it is lowered onto the building.

Ideally, the mounting portion is arranged relative to the sloped portion such that the mounting portion is located substantially underneath the slope in use.

Advantageously, this means that the modular roofing components rests on the surface to which the guide member is mounted and not on the guide member itself in the final position.

Ideally, the angle between the sloped portion and the mounting portion is an obtuse angle.

Preferably, the sloped portion is angled between 40° and 85° to the mounting portion.

Ideally, the sloped portion is angled between 60° and 80° to the mounting portion.

Preferably, the sloped portion is angled at about 70° to the mounting portion.

Ideally, the mounting portion substantially spans the width of a wall plate.

Ideally in one embodiment, in use, the sloped portion extends up from the mounting portion at an angle in a direction towards the gable/end wall.

In another embodiment, where the guide member is mounted on a gable/end wall, ideally the sloped portion extends down from the mounting portion at an angle in a direction away from the wall towards the floor/ground of the building.

Advantageously, if the modular roofing component is too close to the gable wall as it is being lowered it will abut the sloped surface of the guide member and will be displaced away from the gable wall.

In one embodiment, the guide member is mounted at or about the apex of a gable wall.

Ideally, the mounting portion is substantially planar.

Preferably, the sloped portion is substantially planar.

Ideally, the mounting portion and/or the sloped portion are square/rectangular.

Preferably, the one or more guide members are resilient.

Ideally, the one or more guide members are formed at least partially from resilient material.

Advantageously, if the modular roofing component abuts the guide member the resiliency of the material prevents breakage of the guide member and/or of any part of the modular roofing component.

Preferably, the one or more guide members are formed from metal, most preferably steel.

Ideally, the arrangement comprises a lowering means such as a crane for lowering the modular roofing component into a final mounted position.

According to a second aspect of the invention there is provided a guide means mountable on a surface for guiding a modular roofing component into a final position during installation of the modular roofing component on a building.

According to a third aspect of the invention there is provided a building and a modular roofing component arrangeable on the building, the building and/or the modular roofing component comprising a guide means for guiding the modular roofing component into position on the building.

Ideally, the building comprises two mutually opposing gable/end walls.

Preferably, the building comprises and a wall plate.

Ideally, the wall plate extends between the two mutually opposing gable/end walls.

Preferably, the guide means is disposed on the wall plate, and/or one or both gable/end walls and/or a surface of the modular roofing component.

Ideally, the guide means comprises a plurality of guide members.

Ideally, at least one or all of the guide members comprises a mounting portion adapted to be mounted to a surface , and a sloped portion defining a sloped surface in use, wherein the sloped portion extends at an angle from the mounting portion.

Preferably, at least one guide member is mounted on the wall plate with the sloped portion sloping up from the wall plate in a direction towards a proximal gable/end wall, and/or at least one guide member is mounted on a gable/end wall and wherein the sloped portion slopes down from the gable/end walls away from the walls towards the ground/floor of the building, and/or at least one guide member is mounted on a surface of the modular roofing component and wherein the sloped portion slopes upwards and away from the surface of the modular roofing component when the modular roofing component is positioned for installation.

Preferably, the guide means comprises a first guide member and a second guide member, each guide member being mounted on the wall plate.

Ideally, the first guide member is mounted on the wall plate proximal to one gable/end wall and the second guide member is mounted on the wall plate proximal to the other gable/end wall.

Preferably, the first guide member is arranged on the wall plate at a set distance from the proximal gable/end wall, said distance being the same distance as the distance between the second guide member and the gable/end wall proximal to the second guide member.

Advantageously, when the guide members guide the modular roofing component into position, the component is equidistance from the opposing gable/end walls. Further advantageously, by having the guide members arranged at a distance from the gable/end walls there is a space between the wall and the guide member to which the member can deform into if, for example, the modular roofing component abuts the guide member during installation and forces the guide member towards the gable/end wall. This prevents the gable/end wall from being damaged. The guide member can act as a spring to bias the modular roofing component away from the gable/end wall.

In one embodiment, where the first and/or second guide members are mounted on the wall plate, the sloped portion of the first and/or second guide members slopes up from the wall plate in a direction towards the proximal gable/end wall.

Ideally, the first and second guide members are arranged a distance apart, the distance being equal to the width of the portion of the modular roofing component that rests on the wall plate plus 2 to 10 mm.

Advantageously, this extra distance provides a width tolerance between different modular roofing components yet accounts for subtle abnormalities in the size of the modular roofing component and is still small enough to provide satisfactory guidance of the modular roofing component to a final position on the building.

In another embodiment, the first and/or second guide members are mounted on opposing surfaces of the modular roofing component.

Ideally, the sloped portion slopes upwards and away from the surface of the modular roofing component when the modular roofing component is positioned for installation.

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 shows by way of example only one embodiment of a guide means in accordance with the invention. In the drawings: - Figure 1 is a front elevation view of a building and a mono-pitched roofing component being lowered onto the building, the building having two guide members located on the wall plate for guiding the roofing component into position, the arrows indicate the direction of movement of the roofing component during installation; Figure 2 is a front elevation view of the building and roofing component in Figure 1 wherein the roofing component is in its final position on the building; Figure 3 is a perspective view of a wall plate and gable wall with a guide member disposed on the wall plate.

In the drawings there is shown an arrangement for installing a modular roofing component. The arrangement involves a guide arrangement for guiding a modular roofing component into a final position during installation of the modular roofing component on a building. The guide arrangement has a first guide member 1a and a second guide member 1b mounted on a wall plate 2. The guide members 1a, 1b are formed from steel and each comprise a planar, rectangular mounting plate 3a, 3b and a planar, rectangular sloped plate 4a, 4b. The short edge of the sloped plate 4a, 4b is half the length of the long edge of the mounting plate 3a, 3b and the sloped plate 4a, 4b extends from the mounting plate 3a, 3b, centrally located along an elongate edge of the mounting plate 3a, 3b and forming an obtuse angle with the mounting plate 3a, 3b, thereby defining a sloped surface. More specifically, the angle between the sloped plated 4a, 4b and the mounting plate 3a, 3b is at 70° to the mounting plate 3a, 3b. The mounting plate 3a, 3b is located beneath the sloped surface when the guide member 1a, 1b is mounted on a surface. This ensures that any object, such as a modular roofing component, being guided by the guide members 1a, 1b comes to rest on the surface on which the guide members 1a, 1b are mounted, and not on a part of the guide member 1a, 1b itself. The mounting plate 3a, 3b has two apertures 5a, 6a which can be seen on the mounting plate 3a of the first guide member 1a in Figure 3, adapted to receive screws, bolts or other fixing means to releasably mount the guide members 1a, 1b on to the wall plate 2 as shown, or another suitable surface. The apertures 5a, 6a are located at either side of the location of the sloped plate 4a, 4b along the mounting plate 3a, 3b.

The wall plate 2 extends between two opposing gable walls 7a, 7b and the guide members 1a, 1b are located proximal to, but not abutting each gable wall 7a, 7b respectively.

The sloped plate 4a, 4b of each guide member 1a, 1b slopes upwards from the mounting plate 3a, 3b towards, but not touching, each respective proximal gable wall 7a, 7b. This provides a space to which the sloped plate 4a, 4b can deform towards without applying any force to the gable wall 7a, 7b during installation of a modular roofing component, for example, if the modular roofing component were to abut the guide member 1a, 1b. The sloped plate 4a, 4b provides a gradual sloped surface that a modular component can slide along to its final position on the wall plate 2.

In Figures 1 and 2 there is shown a mono-pitched roofing component 8 formed from four trusses 9a, 9b, 9c, 9d with a ridge board 10 and a purlin 11 extending across the trusses 9a, 9b, 9c, 9d. Roofing materials, such as weatherproof material, battens and tiles or slates can be added after installation of the mono-pitched roofing component 8 or prior to installation, e.g., in a factory (not shown). The ridge board 10 defines two eaves 12a, 12b which overhang each gable wall 7a, 7b respectively when the mono-pitched roofing component 8 is installed on a building as shown in Figure 2. The guide members 1a, 1b are arranged at a distance apart along the wall plate 2, the nearest distance between them being mm greater than the distance from the gable—facing surface of a first truss 9a to the gable- facing surface of the fourth truss 9d. Each truss 9a, 9b, 9c, 9d has a joist 13a, 13b, 13c, 13d which rests on the wall plate 2 when the mono-pitched roof module 8 is in its final position as shown in Figure 2.

In use, the guide members 1a, 1b are fitted onto a wall plate 2 as shown in Figures 1 to 3, using the apertures 5a, 6a in the mounting plates 3a, 3b and bolts to mount the guide members 1a, 1b. The guide members 1a, 1b are arranged each defining a slope which extends from proximal each gable wall 7a, 7b away from the gable wall 7a, 7b down to the wall plate 2. Hoisting arrangements (not shown) are attached to the mono-pitched roofing module 8 and the mono-pitched roofing module 8 is then raised and moved into position vertically above the wall plate 2 and between the gable walls 7a, 7b. The mono-pitched roofing module 8 is then lowered gradually down between the gable walls 7a, 7b. As the joists 13a, 13b, 13c, 13d of the trusses 9a, 9b, 9c, 9d approach the wall plate 2, they will abut against either sloped plate 4a, 4b should the mono-pitched roofing module 8 be off-centre.

The guide members 1a, 1b will displace the mono-pitched roofing module 8 towards the centre of the wall plate 2 as it is lowered and if required, ensuring that the module 8 is correctly guided into its final position without requiring slow, careful and awkward final adjustments made by the installers. When the mono-pitched roofing module 8 is in its final position as shown in Figure 2 the hoisting arrangements and the guide members 1a, 1b can be removed. The guide members 1a, 1b can be reused on another building. The mono- pitched roofing module 8 can be further fixed to the wall plate 2 and gable walls 7a, 7b as necessary and roofing materials such as slates and tiles can be fitted as required.

Variations will be apparent to those skilled in the art. For example, the guide members 1a, 1b could be made from any suitable material and do not necessarily need to have rectangular and planar forms. Any geometrical form that can guide a modular roofing component into a final mounted position is within the scope of the invention. Fixing means other than bolts may be used to attach the guide members 1a, 1b to a surface. The guide members 1a, 1b do not necessarily need to be fitted to a wall plate 2. Instead, they could be installed on the gable walls 7a, 7b at a range of positions or on the modular roofing component 8, or a combination of surfaces. Any number of guide members may be used to assist in guiding the modular roofing component 8 into its final position. The modular roofing component need not be a mono-pitched modular roofing component but any object which is mounted on a building or other surface by being lowered into position and is capable of engaging with the guide members 1a, 1b, could be guided by the guide members 1a, 1b into a final mounted position.

In relation to the detailed description of the different embodiments of the invention, it will be understood that one or more technical features of one embodiment can be used in combination with one or more technical features of any other embodiment where the transferred use of the one or more technical features would be immediately apparent to a person of ordinary skill in the art to carry out a similar function in a similar way on the other embodiment.
