Abstract

A modular pitched roof with two outer sections 103 which extend downwards from a ridge section 102 positioned in between them. The ridge section may be supported by the outer modules and/or the exterior walls, which the roof may overhang. One section at least, may be fabricated in a factory and the roof may be covered with slates or tiles. The modules may have shoulder shaped parts, 157 and 158, which connect them to the other modules. The roof may have a floor/ceiling section 155, or a roof space module 150, which engage with a part of the outer pitched modules and extend between the two outer modules. The roof space module can create a habitable space within the roof since it is free of supporting structures. A method of installing the roof is included, whereby the outer pitched modules are lifted onto the walls of the building via lifting gear and stepped surfaces on the modules are engaged with one another.

Description

A MODULAR PITCHED ROOF

The present invention relates to a modular pitched roof for a building. In particular, the present invention relates to a modular pitched roof and a method for manufacturing and erecting the modular pitched roof.

Buildings can have flat roofs or pitched roofs. This invention relates to those buildings having a pitched roof. Pitched roofs are traditionally created using 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 story 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. Furthermore, some roof trusses comprise a series of roof supporting structures, for example, struts, king posts or queen posts, that extend across the roof space thereby preventing the possibility of utilising the roof space

as a habitable room.

It is an object of the invention to mitigate the above-mentioned disadvantages and provide a modular pitched roof.

It is a further object of the invention to provide a modular pitched roof 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 object of the invention to provide a method of manufacturing a modular pitched roof providing prefabricated factory designed modular pitched roof components thereby 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.

It is a further object of the invention to provide a method of erection of a modular pitched roof, the modular pitched roof being capable of being installed without the health and safety risks associated with installing traditional roofs using individual timber frame trusses.

It is a further object of the invention to provide a modular pitched roof having a habitable space.

According to a first aspect of the invention there is provided a modular pitched roof comprising two spaced apart outer pitched modules and a ridge module extending between the two spaced apart outer pitched modules, the ridge module defining the ridge of the roof and the two outer pitched modules defining the pitch of the roof extending downwards from either side of the ridge module.

In the Figures 1 and 2 there is shown a first embodiment of a modular pitched roof indicated generally by reference numeral 1. The modular pitched roof 1 comprises pre-fabricated roof modules which, when assembled, provides an internal space within the modular pitched roof 1, devoid of structural supports such as struts, king posts or queen posts. The embodiment of the modular pitched roof 1 described herein has a ridge module 2 and two outer pitched modules 3a, 3b. The ridge module 2 and the outer pitched modules 3a, 3b are shaped such that, when assembled on a building, the modular pitched roof 1 rests upon and overhangs each wall of the building. The ridge module 2 defines the ridge of the modular pitched roof and the two outer pitched modules 3a, 3b define the pitch extending down from either side of the ridge module 2. One outer pitched module 3a has a surface extending downwards from one side of the ridge module 2 and the other outer pitched module 3b has a surface extending downwards from the other side of the ridge module 2. The ridge module 2 has a ridge portion formed from a plurality of wooden, dual-pitched ridge trusses 4 held together in a spaced apart configuration, equidistance part, by a ridge module structural support arrangement 5. The ridge trusses 4 are held spaced apart in alignment by the ridge module structural support arrangement 5 forming an isosceles triangular prism ridge module 2. The ridge trusses 4 each have a pair of adjoined inclined rafters 6a, 6b, a king post 7 and a tie beam 8.

The ridge module structural support arrangement 5 has two ridge module structural support beams 9a, 9b. The ridge module structural support beams 9a, 9b are steel I-beams but any suitable construction beam could foreseeably be used. The two ridge-module structural support beams 9a, 9b are situated below the majority of the ridge trusses 4 and extend perpendicular to the tie beams 8 and parallel to one another. The two ridge-module structural support beams 9a, 9b extend for the entire length of the ridge module 2 and are joined to the tie beams 8 of the ridge trusses 4. Lifting gear can be attached to the ridge module 2 to raise the ridge module 2. Lifting gear may be attached to the structural support beams 9a, 9b.

Lifting gear can be attached to the internal lifting members 360a, 360b for hoisting the outer pitched modules 303a, 303b. Roofing materials, such as slates or tiles, can be left absent from the portion of the roof vertically above the lifting members 360a, 360b to enable workers to access the lifting members 360a, 360b. Once installed, the roofing materials can then be placed covering the lifting members 360a, 360b. Lifting gear can further be attached to girders 361a, 361b situated at the opposing end of the outer pitched module 303a, 303b to that of the eave portion. The ridge module 302 has a ridge beam 362 located at the apex of the ridge and extending along the length of the ridge module 302. The ridge beam 363 acts as a structural support for the ridge module 302 and can also be used to attach lifting gear thereto for hoisting the ridge module 302. When lowered onto a building, the ridge beam 362 rests on top of a gable wall. In this embodiment, the stepped surfaces between the floor/ceiling cassette 334 and the outer pitched modules 303a, 303b are arranged such that the floor/ceiling cassette 334 can be raised into position from inside the building after the outer pitched modules 303a, 303b are in position. This means that the ridge module 302 can be installed before the floor/ceiling cassette 334 if desired. The floor/ceiling cassette 334 can be held in position by angle brackets 363, for example, that are fixed to the outer pitched modules 303a, 303b.
