Description

TRUE cor-vv T A8 A MODULAR ROOFlNG COMPONENT ,....

The present invention relates to a modular roofing component for use to support a roof of a building. In particular, the present invention relation to a modular roofing component and a method for manufacturing and erecting the modular roofing component.

Buildings can have flat roofs or pitched roofs. This invention relates to those buildings having a pitched roof. Pitched roots are traditionally created by the use of a number of roof trusses comprising wooden frames which are set upon the brick or timber—framed walls of a building, usually on a wall plate. A layer of waterproofing material is laid over the trusses and battens are mounted thereupon which in turn supports tiles 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 which defines the ceiling of the uppermost storey of a building and two angled members 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 heavy lifting 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 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. it is an object of the present invention to mitigate the above—mentioned disadvantages and provide a modular roofing component capable of providing a building with a readily mountable roofing component. it is a further objective of the present invention to provide a modular roofing component which has a more compact overall footprint more suitable for road haulage than conventional roofing components such as trusses for ease of transport to site. it is a further objective of the present invention to provide a method of manufacturing a modular roofing component providing a prefabricated factory designed component reducing time and labour on site for construction, assembly and installation and reducing the risk of compromised quality as a result of poor workmanship on site.

Fire resistant material 202 extends between the inclined surface of the at feast one truss disposed above the party wall 201 and the roofing material 170.

As shown in Figures 6 to 11, where the modular roofing component 101 is formed from a pair of mutually opposing mono pitch roofing modules 104, the structural support arrangements 103 are mutually opposing. The structural support arrangement 103 of each mono pitch roofing module 104 is in alignment with the base surface 110, the bottom surface of the structural support arrangement 103 being coplanar with the base surface 110. in Figure 9 the angle 50 between the base side framing member and the hypotenuse framing member is 35° and the dimensions 51, 52 and 53 are 2457 mm, 5300 mm and 5615 mm respectively, given as non—limiting examples only.

The mono pitch roofing module 104 has roofing materials, in particular, slates 170 are shown in Figures 8 to 11. The modular roofing component 101 also has a ridge cap 171 which extends over the pair of mono pitch roofing modules 104. The cap 171 is fitted to the mono pitch roofing modules 104 at the uppermost point of the hypotenuse framing members.

The cap 171 is an elongate cap. in use, the cap 171 is on the exterior surface of the modular roofing component 101 and on the uppermost point. The cap 171 extends substantially parallel to the structural support arrangement 103. The space on the underside of the cap 171 is filled with expandable insulative foam 172. The mono pitch roofing module 104 in the embodiment shown in Figures 8 and 10 further has fascia board 175 fitted on the inclined rafter surface overhang 108. A gap 176 is formed between the mono pitch roofing modules which is filled with further fire proof material. In addition, a ceiling ledger 177 is used to provide support to the mono pitch roofing modules 104.

L») U: The ridge cap 171 is prefabricated. The ridge cap 171 is installed onsite subsequent to the assembly of the roofing module 110 with the two mono pitch roofing modules 104.

The ridge cap 171 has an elongate structural anchor member 178. The anchor member 178 is for anchoring the ridge cap 171 in the gap 176 between the apex of the two adjacent mono pitch roofing modules 104. The anchor member 178 has a cross bar 179 and batten 221 for stabilising the one or more ridge tiles 222. The ridge cap 171 has a sealing arrangement 172 formed for sealing a gap between the ridge cap 171 and the adjacent roof structure. The ridge cap 171 has sealing arrangement 172 formed for sealing a gap between the ridge tile 222 and the adjacent roof tile 170. The sealing arrangement 172 is an expanding foam, preferably pre-fitted. Advantageously, the foam can be expanded during the installation process.

The mutually opposing upper ends of the mono pitch trusses 102 carry an upstanding board 224 protruding above the top of the roofing module 104. The upstanding board member 224 carries the roofing underlay 225 defining an additional barrier for driven rain.

The expanding foam expands into the gap between at least one ridge tile 222, at least one roof tile 170, the upstanding board 224 and the cross bar 179.

The ridge cap 171 has installation guide assembly 231 to 233.

The installation guide assembly 231 to 233 has at least one elongate installation guide member 232 protruding downwardly from the ridge cap 171.

Advantageously, the installers of the ridge cap 171 operating the guide ropes 231 from the ground have no visibility of the gap between the two adjacent mono pitch roofing modules 104 and so an elongate guide member 232 projecting downwardly below the ridge cap 171 allows an operator to align the ridge cap 171 with the gap 176 using an elongate installation guide member 232. The installation guide member 232 is narrower in width than the leading part of the anchor member 178. Advantageously, it is easier to insert a narrow guide member 232 into the gap 176 than the entire anchor member 178. The installation guide assembly 231 to 233 having a second elongate installation guide member 233 spaced apart from the first elongate installation guide member 232. One of the elongate installation guide members 233 is shorter than the other 232. Advantageously, this allows one operator to insert their guide member 232 first by manoeuvring their guide rope 231 as the ridge cap 171 is lowered down and once this first guide member 232 is in place, this first elongate installation guide member 232 can be used to assist the second operator to insert their shorter elongate installation guide member 233 as they will have a reduced degree of positional adjustment based on the first elongate installation guide member 232 being already located in the gap 176.

The ridge cap 171 having lifting arrangements 241 for coupling lifting gear such as ropes and/or chains 242 to the ridge cap 171. The lifting arrangements 241 of the ridge cap 171 are detachable from inside the roof. The iifting arrangement 241 having a threaded eye 243 and a bolt 244 threaded into the threaded eye 243 via the anchor member 178, the threaded bolt 244 being accessible from inside. Advantageously, an operator can unthread the bolt 244 out of the eye 243 from inside, avoiding workers on the roof. ln order to assemble the roofing module 4, a manufacturing method involves an operator or a machine aligning a plurality of mono pitch roof trusses 2 in a spaced apart configuration in a jig/tool and joining the roof trusses 2 together with the structural support arrangement 3 for forming a mono pitch roofing module 4. Where we say that the method could be carried out by an operative or a machine, it could also be a combination of both. It will of course be appreciated that the machine may be operating under a control system such as computer or pic or some similar electronic control arrangement allowing automation of the process such as selecting, aligning, mechanical coupling of the components. The method comprises prefabricating the mono pitch roofing module 4 in a factory. Advantageously, the prefabricated roofing module 4 reduces labour on site as well as the risk of poor workmanship and allows control over all technical aspects of the roofing module via inspection during manufacture and priorto dispatch from the factory. It also reduces the health and safety risks of installing individual roof trusses at elevated heights on site and reduces the install time and down time due to inclement weather conditions. It also allows mechanical lifting of the entire roofing module 4 directly onto the roof in a single operation without requiring workmen installing trusses at height.

During assembly, the method comprises an operator/machine placing the mono pitched trusses spaced apart a distance in a range of 18 inches apart in alignment and mechanically coupling them together by structural support arrangement 3 for forming a mono pitched roofing module 4. The method comprises the operator/machine placing the mono pitched trusses 2 spaced apart in vertical and horizontal alignment. This creates the triangular prism shape for the roofing module 4. In use, an operative/machine extends the structural support arrangement 3 transverse the upright side framing members 7 of the aligned mono pitch trusses 2 between the end faces 14 of the mono pitch roofing module 4 and most preferably between the gable ends of the building. The operative/machine mechanically couples the structural support arrangement 3 to each of the upright side framing members 7 of the aligned mono pitch trusses 2 by a mechanical coupling joint. This will be done by nailing gusset plates to the joint between the trusses and the structural support arrangement 3. The operative/machine extends the structural support arrangement 3 along the entire length of the upright surface 10 of the mono pitched roofing module 4 between the end faces 14 of the roofing module 4 and most preferably between the gable l\) U: ends of the building. The operative/machine extends the structural support arrangement 3 along a part only of the height of the upright surface 10 of the mono pitch roofing module 4.

Where a modular roofing component 1 with a pair of mutually opposing mono pitch roofing modules 4 is being formed for abutting together at a location across the span of the roof at or about their upright surfaces 10 and their structural support arrangement 3, the operative/machine extends the structural support arrangement 3 of one roofing module 4 along a part of the height of the upright surface 10 of that mono pitch roofing module which part does not overlap with the part of the height of the upright surface 10 of the other roofing module 4 carrying its structural support arrangements. in the embodiment shown in Figures 1 to 5, the structural support arrangement 3 of one roofing module 4 has been extended along a lower half of the height of the upright surface 10 of that mono pitch roofing module 4 and the structural support arrangement 3 of the other roofing module extends along an upper half of the height of the upright surface 10 of that mono pitch roofing module 4, which parts do not overlap. Advantageously, this allows the structural support arrangement 3 of one roofing module 4 to rest against the upright surface 10 of the other roofing module 4. This allows the two roofing modules 4 to abut together so that any forces acting through the roofing modules 4 due to their own weight, snow or wind load are distributed uniformly across the planar surfaces of the structural support arrangements 3.

During installation, an installer provides the building for receiving the mono pitched roofing module 4 with an arrangement in the form of a ceiling ledger for supporting and locating the mono pitched roofing module 4.

Specific to the embodiment shown in Figures 6 to 11 the method involves extending a lifting assembly 191 transverse inclined rafter-surface overhang 108 of the aligned mono pitch trusses 102. When fitted, the lifting assembly 191 transverses the inclined rafter-surface overhang 108 of the aligned mono pitch trusses 102 between and beyond the end faces of the mono pitch roofing module 104. The method further involves mechanically coupling the lifting assembly 191 to the inclined rafter—surface overhang 108 by a mechanical coupling joint. The method involves extending the lifting assembly 191 along the length of the inclined rafter-overhang surface 108 of the mono pitched roofing module 104 and along a part of the height of the upright surface of the mono pitch roofing module 104.

The mono pitch roof module 104 is installed by a method involving the step of raising and positioning a mono pitch roofing module 104 onto a building. The method involves fitting ceiling ledgers 177 to the building prior to raising and lowering the mono pitch roofing module. A hoist arrangement 180 is attached to the structural support arrangement 103 and the lifting assembly 191 . The hoist arrangement 180 is positioned at or close to each edge of the structural support arrangement 103 and the lifting assembly 191 as shown in Figure 8.

The hoist arrangement 180 is attached to the lifting assembly 191 where the lifting assembly 191 extends beyond the inclined rafter-surface overhang 108. The hoist arrangement 180 has a series of chains.

Once the hoist arrangement 180 is attached the mono pitch roofing module 104 is raised and set onto a building as shown in Figure 9, engaging the ceiling ledger 117 in the process. Once positioned the mono pitch roofing module 104 is fixed to the building using bolts (not shown). Then a second mono pitch roofing module 104 is raised and lowered onto the building in the same procedure as the first to form an installed modular roofing component 101.; then a cap 171 is fitted using installation guide members long member first followed by short member using guide ropes and hoisting gear. 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. in the preceding discussion of the invention, unless stated to the contrary, the disclosure of alternative values for the upper or lower limit of the permitted range of a parameter, coupled with an indication that one of the said values is more highly preferred than the other, is to be construed as an implied statement that each intermediate value of said parameter, lying between the more preferred and the less preferred of said alternatives, is itself preferred to said less preferred value and also to each value lying between said less preferred value and said intermediate value.
