    Supporting construction of a building comprising standards and rafters, a rafter and a method of manufacturing a rafter
    The invention relates to a supporting construction of a building comprising standards and rafters supported by said standards, while the rafters are constructed to support a saddle roof of the building. The invention further relates to a rafter, and to a method of manufacturing a rafter which is suitable for supporting a saddle roof of a building.
    Such a supporting construction and the rafters forming part thereof are commonly known in the art. In designing the supporting construction and the rafters to be used thereby there are some conflicting requirements. For one thing the construction must be suitable to have the saddle roof support the load of snow in winter time. In practice the saddle roof must be capable of bearing 80 kg / square meter in the Netherlands; In Russia, however, the saddle roof must be capable of bearing in one area 80 kg / square meter and in another area 480 kg / square meter.
    In earlier times the support capabilities of the saddle roof were simply met by the application of a sufficient amount of steel in the standards and rafters at the expense of high costs. In other designs emphasis was placed on reducing the amount of steel used for the standards and rafters, however at the expense of increased labor costs.
    It is an objective of the invention to provide a supporting construction, a rafter, and a method of its manufacturing which requires a limited amount of labor, and also the amount of steel to be used is close to the minimum amount theoretically required. to provide the supporting construction with sufficient strength.
    According to the invention a supporting construction of a building, a rafter and a method of manufacturing a rafter forming part of such a supporting construction is proposed having the features of one or more of the appended claims.
    The supporting construction of the building according to the invention has the feature that at least part of the rafters is constructed of an I-type beam having a middle part and two parallel side parts which are perpendicular to the middle part, the middle part is provided with a castellated slit in the middle part at predefined distances with respect to the side parts, the resulting two complementary middle part elements are staggered and again welded to each other so as to have these middle part elements define a series of apertures in the middle part between the two side parts.
    This construction saves on weight of steel and requires only a limited amount of labor. The lab is only required for the middle part of the I-type beam slitting operation.
    Beneficially the castellated slit in the middle part is provided at distances with respect to the side parts which gradually increase c.q. decrease looking from a first end of the I-type beam to a second opposite end of said beam, and that before welding the two complementary middle part elements together that are obtained after slitting the middle part, one of said middle part elements is reversed so as to cause that after welding the relevant rafter is funnel shaped.
    This provides the advantage that the supporting strength of the rafters is located where it is needed most, i.e. close to the standards, and that the amount of steel in the rafters at the end that is close to the top of the saddle roof can be kept at a low value.
    If the situation so requires a part of the rafters that is distant from the highest part of the saddle roof can be embodied with a solid beam.
    As mentioned hereinabove, the invention is also embodied in a method of manufacturing a rafter such that it is constructed from an I-type beam having a middle part and two parallel side parts which are perpendicular to the middle part, the middle part is provided with a castellated slit in the middle part at predefined distances with respect to the side parts, and that the resulting two complementary middle part elements are staggered and again welded to each other so as to have these middle part elements define a series of apertures in the middle part between the two side parts.
    The method further preferably has the feature that the castellated slit in the middle part is provided at distances with respect to the side parts which gradually increase c.q. decrease looking from a first end of the I-type beam to a second opposite end of said beam, and that before welding the two complementary middle part elements together that are obtained after slitting the middle part, one of said middle part elements is reversed so as to cause that after welding the relevant rafter is funnel shaped.
    The invention will hereinafter be further elucidated with reference to some exemplary embodiments and with reference to the drawing, showing in Figure 1: an I-type beam from which a rafter according to the invention is manufactured; Figure 2: a rafter according to the invention; -Figure 3: a first embodiment of a supporting construction of a building according to the invention; Figure 4: a second embodiment of a supporting construction of a building according to the invention; and -figure 5: a detail of the supporting construction shown in figure 4.
    Wherever in the figures the same reference numerals are applied, these numerals refer to the same parts.
    Figure 1 shows an I-type beam 1 having a middle part 2 and two parallel side parts 3, 4 which are perpendicular to the middle part 2. Figure 1 further shows that the middle part 2 is provided with a castellated slit 5 in the middle part at predefined distances with respect to the side parts 3, 4.
    For the construction of the rafter 6 as shown in figure 2, the two complementary middle part elements 7, 8 which remain after the castellated slit 5 is complete, are staggered and again welded to each other at the locations 9 so as to have these middle part elements 7, 8 define a series of apertures 10 in the middle part between the two side parts 3, 4.
    Again referring to figure 1 it is shown that the castellated slit 5 in the middle part 2 is provided at distances with respect to the side parts 3, 4 which gradually increase c.q. decrease looking from a first end A, B of the I-type beam 1 to a second opposite end C, D of said beam 1, and that before welding the two complementary middle part elements 7, 8 together which are obtained after slitting the middle part 2, one of said middle part elements 7, 8 is reversed so as to cause that after welding the respective rafter 6 is funnel shaped as shown in figure 2. The figure shows that in the ready rafter 6 the ends A and C of middle part element 8 is adjacent to the ends D and B respectively of the middle part element 7 thus causing the funnel shaped of the rafter 6.
    Figure 3 shows in side view a supporting construction 11 in a first embodiment which is completely made up of rafters 6 manufactured as elucidated above with reference to figure 1 and figure 2. Among the benefits that can be mentioned with reference to this construction 11 are the following: -the rafters 6 with the apertures 10 secure a construction 11 which is very translucent, which is particularly beneficial in agricultural applications such as greenhouses -since also the standards 12 are made from the rafters 6 as shown in figure 2, the presence of the apertures 10 there are arrangements that cables and gutters can be easily guided through said apertures 10 -the construction 11 with the mentioned apertures 10 in the standards 12 and in the rafters 6 also secures a high resistance against pollution.
    Figure 4 shows in side view a supporting construction 11 in a second embodiment in which the standards 12 and the part 6 'of the rafters distant from a highest part 13 of the saddle roof are embodied as solid beams. In this embodiment only the part 6 '' of any rafter is embodied according to the rafter 6 with the apertures 10 and the funnel shape as shown in figure 2. This embodiment of the supporting construction can be suitably applied in regions where a higher load bearing requirement applies for the saddle roof.
    Figure 5 finally provides a detailed view of the rafter as applied in the supporting construction 11 shown in figure 4, with the part 6 'made from a solid beam, and the part 6' 'manufactured in accordance with the rafter shown in figure 2.
