Description Wall connection profile L

The innovation concerns a wall connection profile made of surface-colored metal with an upper flat section that can be placed against a wall with its back, a lower flat section that runs parallel to the front, a middle section that runs at an obtuse angle between the flat sections, an upper end section that is angled from the upper flat section towards the front and a lower end section that is angled from the lower section towards the back.

Such a wall connection profile is known from the Braas handbook 89/90 Sloped roofs, pages 190 and 191. A wall connection profile, also known as a capping strip, is used to seal the upper edge of an angle sheet, breast sheet, side sheet or valley sheet used to cover the gap between a roof surface and a component protruding from it, such as a fire protection wall or a chimney. A sheet metal cover is often used on a pitched roof. The upper edge of the sheet metal ends freely under the wall connection profile, so that the sheet metal can follow any vertical movement of the roof.

Furthermore, a wall connection profile is used, especially on a flat roof, to cover the upper edge of a flexible cover strip. In this case, the flexible cover strip is placed between the protruding component and the

Wall connection profile clamped.

The aim of this innovation is to create a wall connection profile that is suitable both for clamping installation of a flexible cover strip and for a height-adjustable closure of a rigid cover, that can be used on both sides, that can be installed to cover it for extension and that can be easily attached to the component protruding from the roof surface.

According to the innovation, the problem is solved in that the upper flat section and the lower flat section have the same width, that the middle section extends from the two flat sections at an angle of 100° to 130°, preferably 114°, that the upper end section and the lower end section each have the same width and are angled at the same obtuse angle of 100° to 140°, preferably 120° from the adjacent flat sections, that the height of the middle section measured at a right angle to the flat sections is at least equal to the height of the end sections measured at a right angle to the flat sections, and that in the flat sections, preferably in their longitudinal center, watertight sealed openings are arranged at a distance from one another in the longitudinal direction.

Viewed in cross-section, the new wall connection profile is rotationally symmetrical to its central longitudinal axis and has two trough-shaped sections which are equal to one another when rotated 180° around the central longitudinal axis. If the wall connection profile is extended, a second wall connection profile can be placed under the first wall connection profile in the overlap area, leaving only a narrow air gap between the flat sections lying one above the other.

The wall connection profile is easy to install, as the watertight openings in the upper flat section can easily be opened on site at the required fastening points with a pointed object, such as a nail, in order to push a fastening element through.

It is recommended that the openings be made in the form of punched holes, whereby the rounds punched out during the punching process are immediately pressed back into the hole. This creates a watertight seal for the holes. Nevertheless, it is easy to remove the rounds from the wall connection profile using a sharp object. In the case of a hole that is not available

410 339-G

The round blanks remain in the wall connection profile in the lower flat section used for fastening, so that the pre-made holes can only be seen from close up.

When mounted on a protruding from the roof surface

Component/ such as a wall or a chimney, the upper flat section of the wall connection profile is attached to the component protruding from the roof surface and sealed in the area above the upper end section using a sealing compound such as silicone rubber. The lower flat section can cover the vertical leg of an inserted rigid cover so that mutual height shifts are possible.

When installing a flexible cover strip, this

clamped between the component protruding from the roof surface and the upper flat section of the wall connection profile and fastened together with the wall connection profile.

The storage of wall connection profiles is reduced,

if the surfaces on the front and back are colored differently. For example, if the front is brick red and the back is colored brown, a single version of the wall connection profile can be used for differently colored

Covers can be used.

A narrow air gap remaining between the flat sections lying on top of each other when the wall connection profile is extended in the overlap area is avoided if the material thickness of the middle section and the end sections measured at right angles to the flat sections is equal to the material thickness of the flat sections. In other words, the middle section and the end sections have a lower material thickness than the flat sections measured in the direction of the surface normal, so that the front and back have the same contour.

The material thickness ms of the end sections angled at an angle ß from the flat sections and of the middle section is calculated from the material thickness mf of the flat sections according to the formula ms = sinCß - 90°).

The drawing shows a preferred embodiment of the innovation, which is explained in more detail below.

It shows

Fig. 2 the wall connection profile from Fig. 1 in cross section, Fig. 3 the wall connection profile in assembled state for Cover of a height-adjustable cover plate and

Fig. 4 the wall connection profile in assembled state for covering a flexible cover strip.

In Fig. 1, a perspective view and in Fig. 2, a cross-section of an innovative wall connection profile 10 made of 1.5 mm thick aluminum sheet is shown. A 31 mm wide upper flat section 12 can be placed against a wall with its rear side 14. A 31 mm wide lower flat section 16 is provided, running parallel to the upper flat section 12 and offset by 8.5 mm towards the front. Between the upper flat section 12 and the lower flat section 16, a 10 mm wide middle section 18 is provided, which runs at an angle 20 of 114° to the flat sections 12, 16. A 7 mm wide upper end section 24 is provided, angled from the rear side 14 of the upper flat section 12 to the front at an angle 22 of 120°. At the lower end of the lower flat section 16 there is a 7 mm

410 339-G

A wider lower end section 26 is provided, which also forms an angle 22 of 120° with the lower flat section 16.

Since the middle section is wider and angled at a steeper angle 20 of 114° from the flat sections 12, 16 than the end sections 20 and 24, the height of the end sections 24 and 26 measured at right angles to the flat sections 12/16 is lower than that measured at right angles to the flat sections 12/16.

Angle to the flat sections measured height of the

middle section 18. Therefore, the lower end section does not reach the plane of the rear side 14 of the upper flat section 12. The wall connection profile 10 is rotationally symmetrical to the central longitudinal axis 28.

Approximately in the middle of the flat sections 12 and 16,

Longitudinally, watertight sealed openings 30, 32 are arranged at a distance of 20 cm from each other. The openings 30, 32 are punched out as holes with a diameter of 6.5 mm and are sealed by pressing in the punched-out

Ronde closed again. The front of the

Wall connection profile 10 is painted brick red, the back is painted dark brown.

Fig. 3 shows the wall connection profile 10 fastened directly to a wall 34, which is sealed with silicone rubber 36 above its upper end section 24. An angled cover plate 38 protrudes into the space remaining under the lower flat section 16 and can be adjusted in height, resting on a roof covering plate 40. 30

Fig. 4 shows the wall connection profile 10 on a wall 34, with a flexible cover strip 42 being attached to the wall together with the upper flat section 12 of the wall connection profile 14. Above the upper end section 24, the flexible cover strip 42 and the wall connection profile 10 are sealed with silicone rubber 36. The flexible cover strip 42 rests on a roof covering plate 40.
