Description

[0047] The invention is illustrated by the following figures and exemplary embodiments, without being restricted thereto.

[0048] FIG. 1 shows a section of a component set according to the invention, for the production a support grid according to the invention.

[0049] FIG. 2 shows a section of a further component set according to the invention, for the production of a further support grid according to the invention.

[0050] FIG. 3A shows a component set according to the invention.

[0051] FIG. 3B shows a side view of a support grid according to the invention, which is made from the component set shown in FIG. 3A.

[0052] FIG. 3C shows a section of the side view shown in FIG. 3B.

[0053] FIG. 3D shows a view of the support grid according to the invention from FIG. 3B, from above.

[0054] In the section shown in FIG. 1, arrows indicate how top strip receiving grooves 11 made in the support strips 1 and support strip receiving grooves 21 made in the top strips 2 interlock in the specific support grids that are particularly preferred according to the invention.

[0055] According to the present invention, it is preferred that top strip receiving grooves 11 and support strip receiving grooves 21 interlock, for example as shown in FIG. 1. FIG. 2 shows that this does not necessarily have to be the case. In FIG. 2, as claim 1 also covers, the inclination of each top strip 2 is defined by a top strip receiving groove 11 made in a support strip 1, in which the given top strip 2 is received. In addition, the orientation of each support strip 1 is stabilised by at least one support strip receiving groove 21 in which the support strip 1 is received. In the example shown here, one support strip receiving groove 21 is made in each of the top strips 2.

[0056] In all figures, the width of all the grooves 11, 21 is exactly adapted to the thickness of the top strip 2 or support strip 1 which is received in the relevant groove, such that the strips 1, 2 can be received in the grooves 11, 21 with a form fit and friction fit.

[0057] For the sake of clarity, fluid passage openings made in the top strips are not shown in FIGS. 1 and 2. In contrast, they are shown, for example, in the component set in FIG. 3A.

[0058] In FIGS. 3A, 3B and 3D, all support strips 1 and all oppositely inclined top strips 2 of the support grid or component set are clearly visible. Support strips 1 and top strips 2 intersect one another. The view from above in FIG. 3D shows this in a manner similar to the projection described above. It can be seen clearly from FIGS. 3A and 3B that the inclination of each top strip 2 is defined by top strip grooves 11 made in support strips 1. In particular, FIG. 3A shows the top strip receiving grooves 11, which are inclined, rather than being made orthogonal to the upper edge of the respective support strips. The inclination of each top strip receiving groove 11 defines the inclination of each top strip which is/will be received therein in a form-fitting manner 2. The orientation of each support strip 1 is stabilised by a plurality of support strip receiving grooves 21 in which the support strip 1 will be received (FIG. 3A) or is received (FIG. 3B to 3D).

[0059] In the example shown here, there is no other component—only support strips 1 and top strips 2. The support strip receiving grooves 21 are thus made in the top strips 2. In the example shown here, at every point where a support strip 1 intersects a top strip 2, a top strip receiving groove 11 is made in the support strip 1, and a support strip receiving groove 21 is made in the top strip 2. At every point where a support strip 1 intersects a top strip 2, a top strip receiving groove 11 and a support strip receiving groove 21 interlock.

[0060] It can be seen very clearly from FIG. 3C that, at at least one point where a support strip 1 intersects a top strip 2, the depth T of the support strip receiving groove 21 is less than the height H of a portion of the top strip 2 protruding beyond the support strip 1.

[0061] In the example shown in FIG. 3A to 3D, the completely assembled support grid has fluid passage openings 3 in the top strips 2 and between the top strips 2. Fluid passage openings between the top strips 3 are located both between the lower longitudinal edges of the top strips 2 and between the upper longitudinal edges of the top strips 2.

[0062] The material of the strips cannot be seen from the figures. In the example shown here, there are top strips 2 and support strips 1 made of carbon fibre-reinforced carbon (CFC). This is a fibre composite material which cannot be independently integrally bonded and—in the case of the CFC used here—comprises a multi-directional non-crimp fabric (a plurality of layers of unidirectional fabrics arranged on top of one another).

[0063] The support strips 1 and the top strips 2, including all the grooves 11, 21 and the fluid passage openings arranged in the top strips, have been produced by water jet cutting from appropriate CFC plate material.
