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.

Description

Technical field ¹

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a retaining clip for securing a roof tile against a wind, consisting of a hooked head piece of flat material which can be hung on top of the overlapped roofing tile particularly in the rainwater groove region thereof. a tensile strength that can be attached to the roof support structure, wherein the head portion is connected to the hook anchor portion at a variable distance from the attachment point of the hook anchor portion to the roof support structure.

BACKGROUND OF THE INVENTION

The roof tile of the present invention may be both baked clay brick roof tiles and concrete tile roof tiles. The lateral edge regions of the roofing tile, mounted on the roof surface, are provided on one longitudinal side with a rain groove and on the opposite longitudinal side with an overlapping rib with grooves on the underside. Looking towards the roof ridge, the overlapping rib is usually provided on the right side of the tile.

When covering the roof, the individual roofing tiles are placed side by side with partial overlap in rows running parallel to the roof ridge. Within each row, the individual roofing tiles are arranged parallel to each other and are placed side by side from the gable edge such that one area of the lateral section of the next stacking tile overlaps with its overlapping and upwardly projecting ribs provided with shaped grooves on its underside. previously laid side adjacent roofing tiles. The area of the side section is called the side overlap section.

The roofing tiles are mounted in the areas of their upper edge sections facing the ridge of the roofing system, mounted on the roof structure parallel to the ridge of the roof. In addition to the first row of roof tiles located directly above the eaves, the tiles in all other rows are located in their heel area facing the eaves, on the upper surface of the upper edge section of the adjacent tiles closer to the eaves. The overlap region of the head edge portion of one roof tile and the overlap region on the five edge portion of the top tile provide together a so-called height overlap.

The roofing tiles are mounted and held on the roof load-bearing structure under their own weight. However, this force is not sufficient in some extreme cases, so there is a risk that the tiles will rise in a storm or strong wind. In order to eliminate this danger, in some cases retaining clips are used to reliably fix the tiles to the lower roof structure. For roof tiles with lateral grooves to prevent rainwater from penetrating, retaining clips are used to secure the roof tiles against strong winds, called side grooves for the groove edge, and are provided at one end for a hook-like hooking behind the overlap five section of the upper a roof covering tile and for insertion into a rain groove, the clips being at their other end adapted to be attached to the roof support structure, in particular to the roof lattice which they surround.

These retaining clips for securing roof tiles against strong winds, in particular retaining clips adapted to be hooked into the circumferential grooves of the roof tiles are described and shown in Braas Handbuch 91/93 Geneigte Dächer on p. 103, which also describes the assembly of these retaining clips. This retaining clip is formed as a two-piece and consists of a hook-shaped part made of shaped strip material, in the rain grooves of the overlapping edge section. Known retaining clips form a head part connected by a five-wire wire part. jointed with a portion is a panicle.

The mounting of this retaining clip is always carried out when placing a roof tile belonging to the upper row of tiles overlapping the lower row. These known fasteners are relatively difficult to install because the five-piece retaining clip must always be fastened by nailing to a roof batten which is located below the lower edge region of the upper overlapping tile stack facing the gutter, which is thus already covered by the overhead tile tiles.

It is known from AT-PS 23 119 to provide a U-shaped curved section at its upper end, the upper arm of which is mounted on the upper side of the overlapped roofing tile. At the end of the lower limb adjacent to the underside of the roofing tile, a five-part wire wire with a loop is suspended. The free end of the fifth part is bent at a right angle and is provided with a tip. This bent end of the buckle is completely embedded in the roof battens. The five-part is not designed as a spring part and its installation necessarily requires special assembly tools. The same five-piece construction is not always applicable for different spacings, so shorter length five-piece parts must be used as separate parts at a smaller distance between the lower load-bearing roof structure and the upper surface of the roofing tiles. With this solution, it is also not possible to adapt the length of the five-piece part to the actual construction conditions and dimensions during assembly, since the five-piece part with the connecting eyelet must be hung on the head part before assembly.

From the description of German Utility Model DE-GM 81 34 025 it is known to fasten roofing tiles formed by a retainer retained in a loop shaped on the underside of the roofing tiles and connected by a helical spring to a fastening element fixed to the underside of the roof batten. In order to use this kind of roof tile fixing, a special roof tile shape is required. The holding force is exerted solely by the spring force, which depends on the dimensions of the roof tile, on the substructure and on the dimensions of the helical spring. Under tensile stress, the spring can be stretched to any length, and limitation of the spring extension path is not necessary.

The main disadvantage of these known holding clips is that the distance between the fastening point on the roof latch and the hook head part must be pre-set to a certain value. Depending on the profile of the roof tile, however, it is necessary to adapt the distance between its lower side adjacent to the head edge section facing the roof ridge and the upper side of the rain groove. For this reason, the shapes and dimensions of the retaining clips must be adapted to the different types of roofing tiles and their five-wire anchor part must correspond in length to the height of the tile and the supporting structure.

This disadvantage is eliminated with the elastically formed connection clamp according to GB-PS 1 174 891, whose five-piece part is mounted on the roof latch.

Currently, the retaining clips are spaced apart from each other than before. The greater the distance between two adjacent retaining clips, the greater the load-bearing capacity of the roofing materials. Practically this means that the roof battens have to be made with greater thickness or width as the spacing of the retaining clips increases. For this reason, the types of retaining clips described above must be equipped with anchor parts which have special dimensions for the individual sizes of roofing materials.

This disadvantage is eliminated in CH-PS 202 191, of which Fig. 1 shows a retaining clip for securing the tiles against the effects of strong wind, which is also designed as a resilient element. This retaining clip is U-shaped, encircles the roof battens and is stuck at both ends of its arms hooked behind the rain groove of two roofing tiles stacked one above the other from the eaves to the ridge and overlapping in height.

It is also known from DE-GM 88 00 485.6 to consist of a flexible wire and a batten, wherein one end of the groove of the overlapped roof is provided with a plurality of angular one abutting on the eaves side of the angled roofs.

retaining clips are known

FOS, Fr. Ossenberg-Schule +

The elastic retaining clips have the disadvantage that the elastic force is dependent both on the profile of the roof tile and on the dimensions of the roof batten. Flat roof tiles are therefore secured on less roof battens with less force against being lifted by strong winds, for example in a thunderstorm, than more profiled roof tiles mounted on roof battens of larger transverse dimensions.

SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a design of a wind retaining clip which can be easily and without special tools mounted from the top surface of the roof and which is available for all types of roofing and its supporting structure in a uniform anchorage and which can be used. both for roofing tiles of different profiling, as well as for roof structures of different dimensions, in particular roof battens of different thickness and / or width, the length of which can be precisely matched on site to the specific dimensions and spacing of the roof structure elements, so that by fixing the roof tiles to the load-bearing roof structure, the maximum possible tensile force can be permanently ensured.

SUMMARY OF THE INVENTION

This object is achieved by the retaining clip according to the invention, which is characterized in that the hook-like anchor part is L-shaped and its base arm is welded at its free end behind the roof support structure and the section of the head part folded towards the anchor part is provided with a hook for the other arm of the hook anchor member and the upper end of the hook anchor member extending beyond the head portion is bent immediately above the hook to form a tensile strength joint when assembled to the desired position.

When transporting the retaining clips according to the invention for on-site assembly, the head piece is mounted on the upper end portion of another L-shaped arm of the anchor piece. During assembly, the head piece is inserted into the rain groove of a previously laid roof tile from the top of the roof. the tiles and its lower end section are to be weaved behind the lower roof structure. The upper end section of the anchor panel protrudes above the top surface of the roof tile because the anchor panel is of such a length that it extends above the tab formed on the head clip of the retaining clip even when using very thick roofing materials and thick profiled roofing tiles. The upper end section is then pulled by hand until the lower base arm of the anchor part abuts the roof support structure. In this position, the upper end of the anchor part bends immediately above the tab so that a connection is made between the two parts which is able to resist the tensile forces. In particular, the retaining clip according to the invention has the advantage that its final shape and final fit can be accurately and individually matched to the actual structural dimensions of the roof structure. This makes it possible, in any particular case, to fasten the roof tiles to the load-bearing roof cone with a joint that is permanently capable of transmitting maximum tensile force.

A spring insert may be inserted between the head part and the clip anchor part. Particularly high tensile strength of the holding clip can be achieved if the head piece is connected in the pulling direction with the anchor piece by a rigid connection.

A particularly advantageous embodiment of the retaining clip for wind-proofing of the tile is that the retaining clip is formed of only two parts, a head part and a five-anchor part, the head part being directly connected to the anchor part.

The mounting of the retaining clip according to the invention is particularly simple if the head part and / or the anchor part is equipped with an adjustment mechanism with a catch unit for absorbing tensile forces. The adjusting mechanism may be in the form of a cable connector equipped with a spring catching mechanism that allows one of the parts to be coupled in one direction, but in the opposite direction, provides grip with sufficient tensile load.

The flat and wide mounting of the head part of the retaining clip on the upper side of the roof tile is achieved in such a preferred embodiment of the invention, according to which at least the head part is made of a flat, for example tape material. In this case, the head part may be provided with a distance section bent by at least 90 ° for easier bending during assembly.

A particularly reliable fastening of the roofing tiles against pulling or lifting by a strong wind, for example in a storm, is achieved by a further advantageous specific modification of the buckle according to the invention which additionally provides an overlapping edge of the adjacent roofing tile against winding. a section having a U-shaped or C-shaped side view and adapted to snap those onto the edge of an adjacent overlapping roofing tile. The lower leg of this end shaped section of the head panel, which extends approximately horizontally in the final state, can be shaped according to the shape of the top and bottom side of the roof tile or its rain groove, so that this head portion corresponds to the contours of the gap overlapping edge areas of adjacent roofing tiles.

The insertion of the overlapping roofing tile into the shaped end section of the C-shaped head of the clip, fitted to a previously laid roof tile, is facilitated if the head-piece is formed of a resiliently bent band material. The upper arm of the end section of the head part can evolve obliquely upwards at its free end.

If the head part of the retaining clip is formed from a flat, for example tape material, the gap between the superimposed edge portions of the tiles does not increase significantly.

The five-piece anchor part of the retaining clip according to the invention, made of a flat material, can be provided, for example, with a long vertical running portion with an angle of 90 ° which allows the free end of the anchor part to be driven into the lateral side of the roof batten facing the gutter or the roof ridge.

On an approximately vertical section of the five-anchor retaining clip anchorage described above, an end section of the anchoring portion may be formed, with its vertical portion approximately a right angle or, preferably, an acute angle adapted to be received from the bottom surface of the load-bearing roof structure. . The retaining clip thus formed can be retained on the upper side of the roof tile and on the underside of the roof structure, in particular on the underside of the roofing material, without the additional fastening means, wherein the bent end section of the retaining clip is welded on the lower structure either on its underside. or on the side facing the eaves.

A particularly cost-effective embodiment of the retaining clip according to the invention is achieved if its five-anchor part is made of wire or the like. If an additional cushioning effect of the retaining clip is to be achieved, for example to compensate for small dimensional changes in the roofing material due to their drying out or, for example, wet weather conditions, the five-clip retaining clip anchoring part can be formed from a resiliently deformable material.

Since the bent end section of the five anchor part usually fits tightly to the underside of the roofing materials, the joint also resists maximum tensile forces, so that its formation meets the requirements for a rigid tensile joint and is able to withstand considerably greater forces than the bent anchor part. However, if the thickness of the roofing materials decreases as a result of their drying, the roof tiles are still held by sufficiently high tensile forces. Even in severe thunderstorms and winds, the roof tile can only be raised to the extent that the folded end section of the anchor panel does not come back to the bottom surface of the roof batten. As a result, at least one resilient fastening of the roofing tiles is permanently ensured, and when the tensile force is exceeded, a very short stroke immediately follows a rigid connection with sufficient tensile strength. In comparison with the known holding clips which do not have a spring element, the embodiment according to the invention has the advantage that even at low wind speeds the roof tiles cannot be lifted and knocked.

A particular advantage of the retaining clip, provided with a head section with a C-shaped end section twice, is that the retaining clip can also be used to fasten the first row of roofing tiles from the gutter or from the roof ridge or to mount the ridges. Headpiece. In this case, the retaining clip is placed on the front ends of two adjacent combs. Since the ridges are generally laid on pairs of adjacent, overlapping roof tiles, a ridge or gutter roof battens may be omitted if the retaining clip anchors can be fastened to adjacent structural members of the lower roof structure. Particularly simple fastening in the area of the roof ridge is possible, in particular, when the five-anchor part is W-shaped. the section may be connected to the head part. To compensate for a particularly large distance between the fastening points on the lower roof structure and on the head part, for example, the central part of the W-shaped anchor part can be formed at a greater height than the side arms.
