The present invention relates to a construction kit for a collapsible frame structure (1), wherein the construction kit is characterized in that the construction kit comprises flat components of type A (15, 25, 35) and components of at least one type B (20, 30, 40, 45), which are each formed in the shape of rectangles, which each have two long sides and two edge sides, wherein the components of type A (15, 25, 35) and of type B (20, 30, 40, 45) each have a thickness D and each have an identical length L and an identical width W, the components of type A (15, 25, 35) and of type B (20, 30, 40, 45) are each subdivided into n equally large sections of length L/n, which are bounded by n+1 sectional boundaries, wherein the edge sides of the components of types A and B (20, 30, 40, 45) form the respective outer sectional boundaries and the central vertical line between the long sides of the respective components forms the central sectional boundary, wherein the central vertical line is an axis of symmetry S, and wherein, in the components of type A, on a long side of the respective component, n2 slots are arranged along a partial length of the respective sectional boundaries and are located between the edge sides and the axis of symmetry S, and wherein, in the components of type B (20, 30, 40, 45), n4 slots are arranged along selected sectional boundaries and are located between the edge sides and the axis of symmetry S, wherein, starting from a long side, some of the n4 slots are arranged along a partial length of the respective sectional boundaries, and, starting from the other long side, the other n4 slots are arranged on the respective other sectional boundaries, and wherein, starting from a long side, at least 2 of the n4 slots of the components of type B (20, 30, 40, 45) are each arranged along the sectional boundaries and are directly adjacent to the axis of symmetry and, furthermore, starting from the other long side of the component, at least 2 of the n4 slots of the component of type B (20, 30, 40, 45) are arranged along the sectional boundaries and are adjacent to the respective edge sides, and n is 8, 10, or 12. The invention further relates to a method for producing an installation assembly (2) of the construction kit according to the invention and a method for the production thereof.

The invention provides an angled joint component for joining together components of a construction formed from cardboard. The joint is preferably folded from a single piece of cardboard and comprises a plurality of layers held in juxtaposition. The joint may be included in a desk formed from cardboard top and leg sub-assemblies.
