FI102848B - Bracket for fixing roof tiles - Google Patents

Abstract

A storm hook (10) for retaining a tile (16) consists of a hook-like head (12) made of a flat material which can be hooked on the top side of a lapped tile (16), preferably into its water groove (14), and a foot (18) which can be directly linked to the head in a tension-resistant manner and which can be secured to the roof infrastructure (20). The head (12) may be linked to the foot (18) at a variable distance from the spot where the foot (18) is secured to the roof infrastructure (20). In order to create a storm hook which is easy to mount without tools on the top side of a roof, which can be used both for tiles with different profiles and for roof infrastructures of different sizes, in particular those with roof laths of different thicknesses and/or widths, and which can be secured to the roof infrastructure always with the maximum possible tensile force, the foot (18) is approximately L-shaped and its base leg (34) can be hooked at its free end (36) onto the roof infrastructure (20). A holder (28) for the long leg of the foot (18) is provided on a section (26) of the head (12) bent towards the foot (18). The upper end section (30) of the foot (18) which projects beyond the head (12) is bent directly above the holder (28) when the hook is mounted in its appropriate position, thus forming a tension-resistant connection.

Bracket for fixing roof tiles - Stormklammer for fastsättning av en tak-panna

FIELD OF THE INVENTION The invention relates to a bracket for fastening a roof tile, which comprises a top part of a roofing material suspended in position 5, .

For the purposes of the invention, roofing bricks can be both clay roofing bricks and also concrete roofing bricks. 10 The side edge portions of the roof tiles placed on the roof surface are constructed from one long side as a sealing groove and from the opposite long side as a cover groove. Seen in the direction of the roof ridge, the cover groove is usually on the right side.

When roofing, roof tiles are usually placed in several rows running parallel to the roof ridge. In each row, the roof tiles are parallel to each other so that, except for the end tiles, the roof groove of each roof tile covers the water groove of the adjacent roof tile. Side years are called side cover areas.

On its underside, the roof tile rests on the roof ridge installed parallel to the roof ridge, with the edge closest to it. With the exception of the lowest row of bricks closest to the edge of the roof, the lower edge portion 20 of each roof tile is above the upper edge of the adjacent lower row of bricks. Brick '. the upper overlapping area and the lower overlapping area are called the height coverage area.

The roof tiles rest under their own weight on the roof substructure. Therefore, there is a risk that the roof tiles will rise up in a storm. To prevent this, roof tiles «9 · 9 25 can be fixed with brackets to the roof substructure. Side-groove ceilings are fitted with brackets called side grooves, which on the other hand are pushed. The roof tiles are hinged to the lower part of the roof, which is hinged to the lower part. • on the other hand, they can be secured or adhered to the roof substructure, in particular • the rafters.

9 7 a 9 t 1 · 9 a a. 30 "Braas Handbuch 91/93 Geneigte Dächer" illustrates on page 130 these types of fasteners and their installation, in particular the side groove fastener. It is built in two parts and hangs from a flat material hook. : from the upper part to the sealing groove of the vertically covered, laterally covered roof tile 2 102848. The known fastener has a wire-shaped lower part hingedly connected to the upper part, the bent end part of which can be forced into the curb.

This bracket is normally installed when the roof tile is placed in a height-covering row. The installation is cumbersome because the lower part of the bracket must always be forced to attach to the ribbed board, which is located below the adjacent edge of the eaves roof, which is covered in height, and which is thus already covered.

From Austrian Patent 23,119 there is known a press having a U-curved upper part, the upper side of which is resting on the upper side of a covered roof tile. At the end of the lower side resting against the underside of the roof tiles is a hanging lower part of a wire with a loop of light. The free end of the lower part is bent to a rectangle and is provided with a point. This bent head is fully inserted into the curb. The base is not designed to be flexible and cannot be installed without a tool. It is not always possible to use the same lower part for different distances; rather, when there is a small space between the roof substructure and the bricks, there is a small lower part to be manufactured. It is also not possible to adjust the length of the lower part during installation to the actual structural conditions, since before the installation the lower part with the loop has to be hung on the upper part.

German Utility Model Publication 81 34 025 discloses an attachment for a roofing bracket in which a bracket which protrudes into a loop on the underside of the roofing bracket is attached by means of a spiral spring to a fastening element attached to the ribs. The use of this fastener requires specially designed roof tiles. Clamping force: * ma is invariably generated by spring force, which depends on the dimensions of the roof tiles, • structure. i .: of tea and spring itself. The tensile stress can stretch the spring as much as there is no limit on the elastic distance.

The disadvantage of the known fasteners is that the spacing between the fastening point on the curb and the hook-like top is structurally predetermined.

However, depending on the profiling of the roof tile, the distance between the underside of the roof substructure, near the eaves, at the top edge of the top and its upper surface of the sealing groove is different. That's why there are different models of roof tiles • · · v! For this purpose, different fasteners having a wire piercing lower part must be provided for each. ',: Has been matched.

This drawback is avoided in the English Patent Publication No. 1 174 891:. '; in a flexible bracket, the bottom of which can be attached to the curb.

3, 102848

At present, roofing panels are fitted at greater intervals than in the past. The greater the spacing between two roof panels, the greater the load-bearing capacity of one of the battens. As the spacing between the roof rails increases, the rafters must be thicker and / or wider. Therefore, the fasteners described above require tailor-made designs for each of the planking boards of various dimensions.

This drawback is avoided by a fastener known from Swiss Patent Publication 202,191 and described in Figure 1, which is likewise constructed in a flexible manner. It is U-shaped clamped around the battenboard and protrudes at both ends of the flank into a sealing groove for two roof ridge eaves, which are superimposed, 10 in height and covered in height.

Also known from utility model publication G 88 00 485.6 is a flexible wire-shaped bracket that protrudes under the battenboard, one end of which is hooked into the sealing groove of the roof covering the height, and the other end is provided with a plurality of bends, one of which resting on the There are several bends for using different width rafters.

Further, flexible brackets are known from the brochure "Sturmklammem", Firma FOS, Fr. Ossenberg-Schule + Söhne KG, Altena.

A disadvantage of the flexible fastener is that the spring force depends not only on the profiling of the roof tile 20 but also on the dimensions of the curb. Placed on top of a thin lath: '.. the flat roof is thus less protected against storm-induced co::': treatment than a heavily profiled, lofted lath

··· '· It is an object of the present invention to provide a bracket that can be easily installed from above the roof without the use of a tool, having a lower part of the same design, • · * v: available for roofs with different profiles and different dimensioned roofing structures, in particular those with battens of varying thickness and / or: Y: of different widths, the length of which can be individually tailored to the specific dimensions of the building site at the installation site so that the roof tiles are • fixed. 30 teas can always happen with the greatest possible attraction.

. According to the invention, this object is achieved by the bottom part being constructed approximately. f approximately L-shaped, with an L-shaped base flank hooked to the free end. It can be hung on the roof substructure, so that the lower part of the upper part has a holder for the long side of the lower part and that the upper end part of the lower part 4 102848 over the upper part can be bent into a suitable position immediately above the bracket.

In the delivery state, the upper part of the fastener of the invention is positioned in the region of the upper end of the long side of the L-shaped lower part. For installation, the upper part is placed in the sealing groove of the recently installed roof tile from above the roof, the lower part is led past it and the lower end part of the lower part is hooked to the roof area structure. The upper end member extends laterally over the roof tile because it is so long that, even in the case of a very thick ribbed board and very heavily profiled roof tile, it exceeds the attachment point at the top. The upper end portion is then pulled by hand so tightly that the heel side rests against the roof area structure. In this position, the upper end of the lower part is bent just above the point of attachment to form a tensile joint of both parts. The bracket according to the invention has the advantage that it can always make an exact fit of the bracket regardless of the actual dimensions prevailing on the building side. Thus, the roof tile can be attached with a maximum of 15 clubs with possible traction on the roof substructure.

There may be a flexible intermediate between the top and bottom. Particularly high attraction of the bracket is achieved when the upper part can be rigidly attached to the lower part.

A particularly simple design of the bracket is obtained when it consists of only two parts, the upper part and the lower part, whereby the upper part can be directly connected to the lower part 20.

The installation is particularly simple when the upper part and / or the lower part is fitted with: an adjusting device with a locking device that receives the traction force. The adjusting device may be constructed in the same way as a · · · cable binder, whereby a flexible locking device permits unobstructed passage of a part, but · · in the opposite direction is affected by a pull-proof joint.

A particularly storm-proof attachment of roof tiles is achieved, and elevation at the covering edge \ is impossible even in a strong storm if the top has a 30-sided bent end wrapping around an adjacent ·: ·· 'covering roof tile. The approximately horizontal lower flank may be shaped to correspond to the top and bottom profiling of the roof tiles or sealing groove, ''. wherein the top is adapted to the contours of the intermediate spaces between the roof tiles.

• (5 102848

The insertion of the overlay roof tile into the approximately C-shaped bent end of the pre-installed bracket is facilitated if the end member is of elastic elastic material. The upper side of the end portion may be inclined upwards at its free end.

In the space between the roof tiles, the top does not bulge if it is a thin-walled sheet-5 material.

By way of example, the lower part of the bracket material of the bracket according to the invention may have a long, vertically extending intermediate part which is rotated 90 °, whereby it is possible to force it to the side of the ridge side or eaves side.

The bracket portion of the bracket described above extending approximately vertically may have an end portion approximately rectangular, preferably at an acute angle, engaging below the roof substructure. This type of bracket can be pushed without any additional fastening element to the top surface of the installed roofing brick and below the roof base structure, in particular the lath, whereby the bent end portion is fixed to the base structure either from the underside or from the eaves side.

A particularly inexpensive design of the fastener is one in which the underside is made of wire-like material.

If the bracket needs to have an additional spring effect to make it small by example,. Changes in length due to drying or swelling of 20 wooden laths. If the set is leveling, the lower part may be made of elastic material. 1 »

Because the bent end portion of the lower portion rests directly against the underside of the curb, the -m '\ m provides the maximum possible tensile force, corresponding to a rigid traction connection, which significantly exceeds the torsional spring force. But as soon as the thickness of the wood siding

25 dries, the roof tile always stays in place corresponding to the spring force. In a severe storm, the roof panel may only rise to such an extent that ..... the bent end of the lower part is resting again against the underside of the curb. Therefore, a rise due to too little spring force is impossible. Thus, there is always at least one flexible attachment, and when the spring force is exceeded, after a very short distance of 30 seconds, a draw-resistant connection is made. Compared to an inelastic fastener, the model of the invention has the advantage that even at relatively low wind speeds no rattling of roof tiles can occur.

A particular advantage of the bracket, when provided with an upper part having a C-shaped end portion, is that this bracket can be used to fasten the brick placed on the roof ridge or roof fold. In this case, the top is placed against the ends of two adjacent brush bricks. Because the ridge tiles are nor-5 on top of the adjacent, surface-facing roof tiles, it is possible to dispense with the roof ridge or folding batten when the lower part of the bracket can be attached to adjacent structural members of the roof substructure. Particularly simple attachment in the area of the roof ridge is possible when the lower part is constructed in approximately W-shape. The end portions of the lower portion can be secured on both sides to the upper ribs running parallel to the 10 ridge, the middle portion may be attached to the upper portion. In order to smooth out the particularly large gap between the anchorage points in the roof substructure and the top, the center region of the W-shaped bottom may, for example, be constructed higher than the side flanks.
