The invention is characterised by the following features: the roof part (2) is, for transport purposes, divided along a plane which runs through the ridge line (2.3); the two roof members are subdivided into two parts (2.2.1, 2.2.2) along a line (2.2.3) which runs parallel to the ridge line (2.3) and the two parts are articulated to one another along that line (2.2.3) (articulation line); the eaves (10.1) can, for transport purposes, be folded up about a pivot axis parallel to the line (2.2.3).

Description

Prefabricated roof part of a house
The invention relates to a prefabricated roof part of a house. A roof part of this type comprises two roof members comprising the roof leaves and forming an angle with one another in order to form a gable roof shape. The two roof members abut along a ridge line. In addition, the roof part comprises two gable walls. The aforementioned roof members and the gable walls enclose a roof cavity.
Prefabricated houses or prefabricated house parts are particularly popular in the timber-rich Nordic countries and in North America. However, they are also becoming increasingly prevalent in Germany and other European countries. They have numerous advantages: for example, they are cheap owing to their cost-effective fabrication. As they are easy to assemble and dismantle, they do not have to remain permanently in a specific location. The thermal insulation is generally very good.
Prefabricated houses or prefabricated parts have to be transported from the point of manufacture to the point of erection and assembly. This takes place on large transporters which are often specially designed for the purpose. It would be desirable to transport the particular house or house part from the factory to the point of erection in a completely pre-assembled state. Owing to the weight and size, however, this is mostly impossible so that transport has to be effected in sections.
It is known to pre-assemble prefabricated houses of the type described in the introduction at the factory in the form of modules which are produced by dividing the house into a number of slices by means of several vertical cuts produced perpendicularly to the ridge line. These module-type slices are assembled on-site. They have the disadvantage that their measurements in all three dimensions are still very large, at least in the two dimensions in which the cutting plane lies. This results in great weight and unwieldy sizes.
The invention addresses the problem of designing a roof part of a prefabricated house of the type described in the introduction in such a manner that it is constructed from individual members which are readily transportable in terms of weight and size, but which can also be assembled on-site quickly and easily.
This problem is solved by the features of Claim 1. According to that Claim, for transport purposes, the roof part is divided along a plane which runs through the ridge line; furthermore, the two roof members are subdivided into two parts along a line which runs parallel to the ridge line and the two parts are articulated to one another along that line.
Therefore, the whole roof part comprises two individual elements or modules divided along the ridge line. Although the two elements or modules may be relatively long (depending on the length of the house, viewed in the direction of the ridge line), their measurements in the other two dimensions are relatively small so that, in most cases, lorries without special fittings can be used.
The invention is not restricted to roof parts which are components of prefabricated houses. Rather, a roof part according to the invention can also be a component of a house whose lower storey(s) is(are) manufactured conventionally. The house concerned may also be a so-called "roof-only house" where the entire house consists solely of the roof part.
The invention is described more fully with reference to the drawings which, in detail, illustrate the following:
Figure 1 is an exploded view of a prefabricated house having a roof part according to the invention.
Figure 2 shows the subject of Figure 1 in the assembled state.
Figure 3 shows parts of a gable wall of the house.
Figure 4 shows a prefabricated house which is assembled conventionally from slice-like modules.
The prefabricated house illustrated in Figures 1 and 2 comprises a lower storey 1 and a roof part 2. The invention relates to the roof part. The roof part comprises two roof members 2.1 and 2.2 and, in addition, an attic storey which is composed of two parts 3.1 and 3.2. The two parts 3.1 and 3.2 of the attic storey are identical in construction. They are arranged as mirror images of one another.
Above the attic storey 3.1, 3.2 there is a prism-shaped space, the so-called ridge cavity, which is hollow in the present case. It has end walls 4.1 and 4.2 which, together with the end walls of the attic storey parts 3.1 and 3.2, form the gable face. The two roof members 2.1 and 2.2 are fitted together in the assembled state along the ridge line 2.3 (see Figure 2).
The lower storey 1 is also constructed from identical parts 1.1 and 1.2 which are arranged symmetrically to each other. These two parts are also prefabricated in the present case.
A decisive feature of the invention is evident in Figure 1. As can be seen, each roof member 2.1 and 2.2 is constructed from two parts. This can be seen very clearly in Figure 1 from the illustration of the roof member 2.2 on the right. This roof member comprises a lower part 2.2.1 and an upper part 2.2.2. The two parts of each roof member are articulated to one another, as shown by the articulation line 2.2.3 in Figure 1. In the present case, the lower part 2.2.1 of the roof member 2.2 is secured to part 3.2 of the attic storey before leaving the factory. The upper part 2.2.2 is folded about the articulation 2.2.3 in such a manner that it almost rests or rests entirely on the lower part 2.2.1. The entire object is transported to the building site in this state. At the building site, the upper roof member part 2.2.2 is folded upwards so that the rafters 2.4, 2.5 adopt the position represented by the broken line.
The two roof members 2.1 and 2.2 each have eaves 10. Figure 1 illustrates this most clearly, on the right-hand side. These eaves 10 are a relatively narrow strip of the roof member 2.1 or 2.2. Eaves of this type project, in the assembled state of the house, not only beyond the gable wall, but also beyond the longitudinal side wall. The eaves would be very problematic during transport. For this reason, the eaves 10.1 are folded up for transport purposes. The part folded up is, therefore, in strip form and extends over the entire length of the house.
It will be appreciated that the left-hand roof member 2.1 is constructed in the same manner.
In accordance with another aspect of the invention, it is also possible to articulate the two parts 2.2.1 and 2.2.2 of the roof member 2.2 to each other in such a manner that pivoting of the upper roof member part 2.2.2 for the purpose of transport takes place in another direction, therefore not towards the lower roof member part 2.2.1, but in the opposite direction so that the upper roof member part 2.2.2 rests horizontally upon the right-hand part 3.2 of the attic storey during transport. During the assembly of the complete roof part 2, part 4.2 and the corresponding opposite part 4.1 are inserted so that the ridge cavity is closed off.
The Figures show further details which are not necessarily important to the invention. For example, Figure 2 shows the roof battens 2.6 from which, for instance, roof tiles can be suspended. Figure 3 shows beams 3.4 from which the end face of the attic storey is constructed. Figure 4 shows how the conventional prefabricated house depicted here is constructed from slice-like modules 5.1 to 5.5.
