Description

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, wherein the rafters are construed for supporting a saddle roof of the building. The invention further relates to a 5 rafter, and to a method of manufacturing a rafter that 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 10 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 to bear 80 kg/square meter in the Netherlands; in Russia however the saddle roof must be capable to bear in one area a 80 15 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 the reduction of 20 the amount of steel used for the standards and rafters, however at the expense of increased labour costs.
It is an objective of the invention to provide a supporting construction, a rafter, and a method of its manufacturing which requires a restricted amount of labour, and wherein 25 also the amount of steel to be used is close to the minimum amount that theoretically is 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 30 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 construed out of a I-type beam having a middle part and 35 two parallel side parts that are perpendicular to the middle part, wherein the middle part is provided with a castellated slit in the middle part at predefined distances with respect to 2 the side parts, wherein 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.
5 This construction saves on weight of steel and requires only a limited amount of labour. The labour is only required for the slitting operation of the middle part of the I-type beam.
Beneficially the castellated slit in the middle part is provided at distances with respect to the side parts which 10 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 weld-15 ing the concerning rafter is funnel shaped.
This provides the advantage that the supporting strength of the rafters is located there where it is needed the most, i.e. near to the standards, and that the amount of steel in the rafters at the end that is close to the top of the saddle 20 roof can be kept at a low value.
If the situation so requires a part of the rafters that is distant from a highest part of the saddle roof can be embodied with a solid beam.
As mentioned herein above, the invention is also embod-25 ied in a method of manufacturing a rafter such that it is construed out of a I-type beam having a middle part and two parallel side parts that are perpendicular to the middle part, wherein the middle part is provided with a castellated slit in the middle part at predefined distances with respect to the side 30 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 35 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 40 slitting the middle part, one of said middle part elements is reversed so as to cause that after welding the concerning rafter 3 is funnel shaped.
The invention will hereinafter be further elucidated with reference to some exemplary embodiments and with reference to the drawing, showing in 5 -figure 1: a 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; 10 -figure 4: a second embodiment of a supporting con struction 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 15 applied, these numerals refer to the same parts.
Figure 1 shows a I-type beam 1 having a middle part 2 and two parallel side parts 3, 4 that 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 prede-20 fined 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 that remain after the castellated slit 5 is complete, are staggered and again welded to each other at the locations 9 so as to have 25 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 30 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 that are obtained after slitting the middle part 2, one of said middle part elements 7, 8 is reversed so as to cause that after 35 welding the concerning 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 are adjacent to the ends D and B respectively of the middle part element 7 thus causing the funnel shaped of the rafter 6.
40 Figure 3 shows in side view a supporting construction 11 in a first embodiment that is completely made up of rafters 6 4 manufactured as elucidated above with reference to figure 1 and figure 2. Amongst the benefits that can be mentioned with reference to this construction 11, are the following: -the rafters 6 with the apertures 10 secure a construc-5 tion 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 therein arranges that cables and gutters can be easily guided through 10 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 15 11 in a second embodiment in which the standards 12 and the part 6' of the rafters that is distant from a highest part 13 of the saddle roof is 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. 20 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, 25 with the part 6' made from a solid beam, and the part 6'' manufactured in accordance with the rafter shown in figure 2.
