| 摘要 |
The invention relates to a modular construction system, comprising at least two profile parts for mutual releasable coupling by means of a coupling part, wherein the coupling part is provided on at least two different sides thereof with one or more radially protruding lips and with a recessed portion present behind the lips as seen in coupling direction, and wherein each profile part is provided in at least one wall thereof with a continuous opening with different dimensions as seen in at least two different radial directions, wherein the larger dimension is larger than or equal to the maximum radial section through the lips and wherein the smaller dimension is smaller than said radial section, wherein the wall thickness at the position of the opening is smaller than or equal to the width of the recessed portion on the coupling part, this such that coupling takes place by receiving of the lips in the opening and by subsequent radial rotation of the coupling part and each profile part relative to each other. |
