Description

SPECIAL DESCRIPTION PART

[0048] Hereinafter, the subject matter of the invention will be explained with reference to figures without limiting the subject matter of the invention herein. It is shown:

[0049] FIG. 1: Example of embodiment of the process 100;

[0050] FIG. 2: Exemplary processing of a floor plan 1 with conveniently placed construction joints 12;

[0051] FIG. 3: Example of processing a floor plan 1 with awkwardly placed construction joints 12;

[0052] FIG. 4: Example of embodiment of process 300.

[0053] FIG. 1 shows an embodiment of the method 100. In step 105, the predetermined floor plan 1 is provided by the user, in this case including one or more construction joints 12. In step 106, the amount of concrete and/or wall length required for the realization of each cycle is calculated, and this required amount of concrete and/or wall length is compared with a predetermined threshold value in step 107. If the threshold value is exceeded (truth value 1), a warning is issued to the user in step 108, and/or a suggestion is made to the user in step 109 for a displacement of at least one construction joint 12 in such a way that, when this suggestion is implemented, the predetermined threshold value is no longer exceeded.

[0054] In step 110, catalogue 3 is provided associating patterns 31a-33a for courses of planned walls 11 respectively with a spatial arrangement 31b-31b of formwork elements. According to block 111, this catalogue 3 may be selected, for example, from a plurality of catalogues 3a-3c, depending on the optimization objective pursued in the creation of the formwork plan 2.

[0055] In step 120, occurrences of patterns 31a-33a from the catalog 3 are searched for in the floor plan 1. In doing so, these patterns may be rotated and/or scaled according to block 121. Alternatively or also in combination, according to block 122 first changes of direction and/or branches of walls may be searched for, before subsequently straight walls are searched for according to block 123. As described above, however, straight walls can also be added subsequently, for example in the course of drawing or closing gaps.

[0056] In step 130, for each occurrence of a pattern 31a-33a, the spatial arrangement 31b-33b of formwork elements associated according to catalogue 3 is added to the formwork plan 2. In doing so, the spatial arrangement 31b-33b is optionally rotated and/or scaled in the same manner as was done with the pattern 31a-33a. The occurrence of the pattern may optionally be marked as processed in a representation of the floor plan 1 at step 140. As previously described, however, this is not obligatory, because the fact that formwork elements are planned at a certain position in the formwork plan 2 already indicates that a part of the floor plan 1 corresponding thereto has been processed.

[0057] In step 150 it is checked whether the given floor plan 1 is completely processed. If this is the case (truth value 1), the formwork plan 2 is converted into an order list 6 for formwork elements in step 240 by comparison with a list 5 of orderable formwork elements. This can be, as previously described, in particular a maximum list.

[0058] If the given floor plan 1 has not been completely processed (truth value 0), a check is first made in step 160 as to whether the catalog 3 contains further patterns 31a-33a which have not yet been searched for in the given floor plan 1. If this is the case (truth value 1), one of these further patterns 31a-33a is used to branch back to search 120.

[0059] If, on the other hand, there are no more patterns 31a-33a which have not yet been searched for, then it is checked in step 180 whether a construction joint 12 divides an area 1a of the floor plan 1 which has not yet been processed. If this is the case (truth value 1), then the area 1a is examined for patterns 31a-33a in step 190 while hiding the construction joint 12. In step 195, it is checked whether a pattern 31a-33a has been found. If one was found (truth value 1), the awkwardly set clock groove 12 was responsible for the pattern 31a-33a not being detected. It is then possible, in step 200a, to automatically offset and/or rotate the construction joint 12 so that it no longer breaks the found pattern 31a-33a, i.e. so that the wall course can be produced “from one cast” in accordance with this pattern 31a-33a. Alternatively, or in combination, the user may be prompted to make such a change to the construction joint at step 200b. The creation of the formwork plan 2 can then be started again from step 110.

[0060] FIG. 2 shows a simple exemplary floor plan 1 with planned walls 11. The floor plan 1 is divided into three working cycles A, B and C by two construction joints 12. This means that separate formwork plans 2 are required for each of the three working cycles A, B and C. The formwork plans 2 for each of the three working cycles A, B and C are shown in FIG. 2. The walls planned for each working cycle A, B and C end at the construction joints 12 and 13 respectively, which limit this working cycle.

[0061] The catalogue 3 used in this simple example includes three patterns for courses of planned walls 11, namely right-angled changes of direction 31a of walls 11, T-shaped branches 32a of walls 11, and straight pieces 33a of walls 11.

[0062] When converting the floor plan 1 into a formwork plan 2 for each working cycle A, B and C, the occurrences of right-angled direction changes 31a in the floor plan 1 are searched for first. In the first working cycle A and in the third working cycle C there are two such occurrences each, in the second working cycle none. The spatial arrangements 31b of formwork elements assigned to the right-angled directional changes 31a according to the catalogue 3 are added to the respective formwork plans 2 for the working cycles A, B and C. The spatial arrangements 31b of formwork elements assigned to the right-angled directional changes 31a according to the catalogue 3 are added to the respective formwork plans 2. The right-angled directional changes 31a are thus processed, which is indicated by their dashed drawing in the floor plan 1.

[0063] Next, the occurrences of T-shaped branches 32a in the floor plan 1 are searched. Here, there are only two occurrences in the second working cycle B; none in the first working cycle A and none in the third working cycle C. To the respective formwork plans 2 for the working cycles A, B and C are added the spatial arrangements 32b of formwork elements assigned to the T-shaped branches 32a according to catalogue 3. The T-shaped branchings 32a are thus worked off, again indicated by dashed drawing in the ground plan 1.

[0064] Finally, the occurrences of straight wall pieces 33a in the floor plan 1 are searched for. Here, there are three occurrences in the first working cycle A, four in the second working cycle B and three again in the third working cycle C. To the respective formwork plans 2 for the working cycles A, B and C are added the spatial arrangements 33b of formwork elements assigned to the straight wall pieces 33a according to catalogue 3. The straight wall sections 33a are thus completed, again indicated by a dashed drawing in the floor plan 1.

[0065] In this simple example, floor plan 1 has thus been completely worked through and transferred to formwork plans 2 for the individual working cycles A, B and C.

[0066] In the example shown in FIG. 2, the catalogue 3 contains only one copy each of the right-angled change of direction 31a, the T-shaped branch 32a and the straight wall piece 33a. For the search of occurrences in the floor plan 1, these elements are each suitably scaled and/or rotated.

[0067] FIG. 3 shows another simple example of a floor plan 1 which is divided into two working cycles A and B by a construction joint 12. In this example, however, the manual placement of the construction joint 12 is inconveniently chosen, since in the upper left corner and in the lower right corner of the floor plan the planned wall 11 ends at the construction joint 12 in a slope, respectively, which does not occur in the catalogue 3 as pattern 31a-33a. Accordingly, after the detection of the rectangular directional changes 31a and the straight wall portions 33a shown in FIG. 3, there remain areas 1a of the floor plan 1 that have not yet been worked through. One embodiment of the method 100 provides for moving and/or rotating the construction joint 12, and/or prompting the user to make such a change. For example, if the construction joint 12 is changed to the construction joint 12′, the same catalogue 3 of patterns 31a-33a can be used to process the entire floor plan 1, as in FIG. 2.

[0068] FIG. 4 shows an example of an embodiment of the method 300 for the construction of a building. In step 310, at least one formwork plan 2 is created from the planned floor plan 1 in accordance with the method 100. In step 320, a spatial arrangement of formwork elements conforming to this formwork plan 2 is produced. In step 330, a cavity defined by this spatial arrangement is filled with a concrete.
