DE1483883C3 - Compression-resilient clamping connection for the route extension consisting of overlapping channel profile segments - Google Patents

Description

Appropriately, according to a further feature of the invention, the plate is designed so that the locking lugs get a square or approximately square cross-section.

According to a further feature of the invention, the side surfaces of the locking lugs are in the direction of insertion designed to converge. This makes it easier to install the plate when the Plate must be inserted against resistance from the mountains or the delay.

The invention is explained below with reference to the exemplary embodiment shown in the drawing. It shows

F i g. 1 shows a side view, broken away two overlapping channel profile segments and the clamping connection according to the invention and

F i g. FIG. 2 shows a plan view of the object according to FIG. 1.

The enclosed channel profile is denoted by 1 in the figures. The surrounding profile carries that Reference number 2. The screw connection according to the invention sits at the front end of the enclosed profile 1. It consists of a bracket 3, which surrounds the enclosing profile 2 on the outside and the two Lateral extensions 4 and 5 with holes to accommodate the shafts 6 of hook bolts 7 and 8 having.

The end face of the enclosed profile 1 lies for the greater part in the enclosing profile 2, however, the end faces 9 and 10 of the flanges 11 and 12 of the enclosed profile 1 as well as the End faces of the adjoining parts of the profile legs are arranged so that they are above the flanges of the enclosing profile 2 lie.

ίο On these faces of the face of the enclosed Profile 1 are supported by locking lugs 14 and 15, which are part of a plate 16 are trained. The plate 16 has a bulge 17 for receiving the screw connection. To the arch This is followed by a plate section 18 which is bent upwards at a substantially right angle. In the Insertion direction (see. The arrow "in Fig. 1) the front surface 19 of the section 18 runs at right angles to the plate surface and serves to support the hook heads 20 and 21 of the two screws 7 and 8.

The locking lugs have, as shown in FIG. 1 using the example of the lug 14, a square or approximately square cross-section. The side surfaces 22 and 23 converge in the direction of insertion a.

Front side of the enclosed profile arranged In such a tensioning connection, the anist and a plate, which acts on the front end of the mounting surfaces of the tabs for the hook bolts, are located with a bulge far below the hook heads. As a result, the practice is provided that the screw connection is relatively long lever arms, which are heard, characterized in that the hook screws tilting favor. In addition, to support the plate (16) on the front side, the connection is relatively expensive because of the two plates (16) inserted for each profile (9, 10) of the enclosed profile (1) on the tabs required in the side and the profile (1) ) Lateral ar- 15 correspondingly difficult to attach,

Then the front edge of the enclosed profile loses its support on the plate, so that 35 the desired anti-tipping device is lost. It is also not possible to use the previously known connection The invention relates to a pressure-resilient dung to use hook head screws because the tensioning connection for the overlapping curvature for a reliable support of the existing track expansion of the relatively small hook heads is not sufficient,
