DESCRIPTION OF THE PREFERRED EMBODIMENT
(9) FIGS. 1a and 1b show an elongate, rectangular main body 2 according to the invention, having two longer sides 15 and two shorter sides 16, said main body 2 having three different fastening devices 3, 4, 5. The first fastening device 3 is provided twice as a through-opening in the form of an oblong hole in the central region 7 of the main body 2, in particular with the long side parallel to the shorter sides 16. These advantageously allow the fitting to shift when the dimensions of the board change, without a screw that passes through the oblong hole tearing out. Of course, round or polygonally configured through-openings are also in accordance with the invention, in particular when carriage bolts are intended to be used as fastening means. The second fastening device 4 is likewise in the form of a through-opening, but in this case with a stepped radius, as seen axially, in order to allow a fastening means 12 to be countersunk, resulting in a flat surface. This allows clean introduction of a board 13 to be laid at a board 13 already fastened to a supporting body 14 beforehand by a second fastening device 4. The third fastening device 5 is in the form of a through-opening with an H-shaped cross section. Each spacer 9 which is shown in three different embodiments in FIG. 1a, fits, as illustrated in FIG. 1b, into the third fastening device 5 configured in a uniform manner for each main body 2, since the thickness of that part of the spacer 9 that is to be arranged orthogonally to the longer side of the main body 2 corresponds to the thickness of the corresponding connecting portion 10 of the third fastening device 5. The cross section of the spacer 9 is formed in an H-shaped or rectangular manner according to the invention. FIGS. 1a and 1b show a further variant of the spacer 9 with a less pronounced H-shaped cross section. The main body 2 has two grooves 6 which separate the central region 7 of the main body 2 from the two end regions 8.
(10) FIG. 2 shows a detail view of the main body 2 according to the invention with the third fastening device 5 and a groove 6. The groove 6 marks the boundary between the end region 8, in which the third fastening device 5 is located, and the rest of the main body. The third fastening device 5 is in the form of a through-opening and has a connecting portion 10 between the two thickened ends of the H-shaped through-opening. Three protrusions 11, which are in the form of semicircles here, can be seen. These can be deformed to such an extent by relatively light force exertion when a spacer is introduced that the latter is held in a force-fitting manner.
(11) FIGS. 3a to 3d explain the method according to the invention for laying and fastening boards 13 on a supporting body 14 by means of the fittings 1. FIG. 3a shows the fastening of the fitting 1 to the underside of a board 13, for which purpose the fitting 1 is held with its corresponding side on the board 13 and is fastened to the latter by means of fastening means 12 which are embodied here as screws, specifically by way of the first fastening device 3. It can be seen that the main body 2 has stiffening webs both along the longer and shorter sides 15, 16 and in the region in between, in this case three webs parallel to the two outer webs on the shorter side 16. The first and second fastening devices 3, 4 in the form of the through-openings that are the oblong hole and axially stepped round hole are in this case likewise provided with circumferential webs for reinforcement and for creating a uniform underside lining. It would also be in accordance with the invention to manufacture the main body from a solid material into which the through-openings are introduced. The manner of construction illustrated saves material and weight, however, with the same stability.
(12) In a similar manner to the second fastening device 4 in FIG. 1a, the through-openings in the first fastening device 3 have a stepped radius as seen axially, in order to countersink the fastening means 12 in the through-opening. The fitting 1 protrudes with its two ends 8 beyond the board width. As a result, both the second fastening device 4 and the third fastening device 5 are located next to the board 13. The board 13 is fastened to the supporting body 14 by means of fastening means 12, in this case screws, which pass through the second fastening device 4 of the fittings 1. In the process, the fitting 1 is only fastened to the supporting body 14 after the board 13 has been positioned thereon. Subsequently, the board 13 with fastened fittings 1 is placed on a supporting body 14 and pushed towards the already mounted boards 13 until the spacers 9 bear against the already laid board 13 and define the desired joint. Finally, FIG. 3d shows the removal of the spacers 9 from the third fastening device 5 of the main body 2 already attached to the supporting body 14. As already mentioned above, the order of the working steps is interchangeable.
