Abstract

The present invention relates to a fixing system for roof coverings or wall coverings on large surfaces. An object of the present invention is to provide one fixation system, which is structurally easy to configure, consists of few members, can be quickly assembled, and is expensive. Suitable for negative wind loads. This fixing is performed inside the upright longitudinal ribs 2, and these longitudinal ribs are formed by the upright sheet metal legs 11. These longitudinal ribs 11 are bent and have a protrusion 13. According to the present invention, inside the erect longitudinal rib 2, a T-shaped base strip 3 extending longitudinally, consistently or only in places is arranged and fixed. It is possible that both horizontal legs of the T-shaped base strip 3, referred to as the foundation legs 5, are arranged downward or upward. In these T-shaped base strips 3, recesses 6 are formed on the left and right sides in the vertical legs of these T-shaped base strips 3 in a state of reaching the foundation leg 5. .. A specially formed protrusion 13 of the roof element, the sheet metal plate, or the sheet metal leg portion 11 of the sheet metal strip 1 is engaged in the recessed portion 6. These preformed protrusions 13 generate shape engagement in the central leg 4 or in the context of the pressing plate 9 which can be placed on the central leg 4. These pressing plates 9 are fixed to the base strip head 7 in an engaged state by shape or, for example, screwed in a suitable structure and method. The pressing plates 9 are formed so that the pressing plates 9 cover the protruding portion 13 of the sheet metal leg portion 11 of the roof element, the sheet metal plate or the sheet metal strip 1 located side by side. .. This results in a durable, shape-engaged coupling using the T-shaped base strip 3 (or base element), the central leg 4, and the pressing plate 9. At the upper end of the sheet metal leg 11 projecting upward, the entire longitudinal rib is formed upwardly closed by the cover strip 12.

Description

The present invention is of a large surface made of metal for fixing a planar roof element, sheet metal plate or sheet metal strip, which can be arranged side by side, on an under-roof structure or under-wall structure. Regarding fixing systems for roof coverings or wall coverings
At that time, the roof element, the sheet metal plate, or the sheet metal strip-like body is formed to be flat in a plane, corrugated, or contoured.

In laid and side-by-side sheet metal strips for roof coverings or wall coverings, or thinned roofing boards with large faces, on the other hand, fixing means through the roof panels are abandoned. Should, however, on the other hand, strong gusts or suction of hurricane-class storms ensure that the roof panel is securely fixed on the underlying structure of the carrier located beneath this roof panel. There is a danger that it is necessary.
The individual adjacent roof sheet metals, however, should allow for tight overlap of partially very large, differently sloping and differently curved roofs or walls. In a given roof shape, this suction action can be additionally enhanced within the individual regions, solely by the bends. The interaction between positive and negative wind loads and temperature fluctuations introduces additional loads.
The requirement for roof fixing should suppress the effects of positive wind load (pushing force), negative wind load (tensile force), expansion during heating, and contraction during cooling (sliding force and shear force). And nevertheless, hermeticity should be guaranteed. Therefore, the structure and laying method in which the individual sheet metal strips or sheet metal plates are held along the interconnected longitudinal ribs on the roof panel of the under-roof structure or under-wall structure. Achieved.
A series of different roof fixings are known, and for reliability reasons, fixing means are used in these roof fixings, which are spaced apart from each other and penetrate the roof panels, which sooner or later always It induces the problem of sealing of such roof coverings or wall coverings. This is therefore unsuitable for numerous roof and wall arrangements and requires high maintenance costs.
Roof coverings or wall coverings, which are sufficient without roof penetrations, are therefore advantageous. Usually, therefore, differently configured, internally placed retainers are used for fixation, and these retainers should secure the roof panel with high reliability. These holders are arranged at predetermined intervals from each other according to their respective structural modes. At that time, the sheet metal strip covers the next sheet metal strip so that the airtightness can be formed.

Such a technical solution is known from Patent Document 1, and in this solution, a shaped sheet metal strip in which roof coverings are arranged side by side is used. At that time, on one side, in the same direction, a sheet metal strip located beside it covers the next sheet metal strip along the longitudinal ribs formed upward. To ensure sufficient fixation, these sheet metal strips are held on the under-roof structure by different bending folds that are fixed in a shape-based engagement into the hook-shaped retainer.
However, this fixing solution presupposes a differently preformed sheet metal strip. A hook-shaped holder is utilized for this fixation, and the hook-shaped holder is fixed on the underside structure of the carrier. The hook-shaped retainer is generally screwed to the underside structure as usual. It is possible that this hook-shaped retainer is then molded differently.
However, in this fixing mode, it is always possible to fix the sheet metal strip-shaped body in an engaged state by a pure shape with a screwed holding element located inside. Due to the variety of acting forces, the engagement by shape, however, can bend and open when viewed over longer time intervals, and the strength is totally covered by the individual sheet metal strips during a storm. Is small enough to be removed.

In Patent Document 2, a modular system for a wall structure is described, wherein a plate-shaped building surface structure can be clamped and fixed within a holding element, and each plate element at that time. In, on the left and right sides, the flanges are arranged at a predetermined angle, and the free ends of these flanges are formed in a curved manner, thus creating protrusions at these ends, which are these. The protrusion engages into the recess of the holding element. This holding element is screwed to the underside structure.
This solution has the disadvantage that the engaged coupling by this shape can withstand high negative wind loads only conditionally, and further, the structure of the building surface is not water resistant. Is accompanied by.

In Patent Document 3, another roof covering consisting of sheet metal strips located side by side is described, and the roof coverings are joined to each other on both sides over the longitudinal ribs formed in the assembly mode. And, further, it is sealed in the same manner.
For fixation, so-called holding strips are screwed onto the under-roof structure. On the left and right sides, the holding strips are arranged with upright hooks, and the heads of these upright hooks are curved sideways in a hook shape. These sheet metal strips have longitudinal ribs that stand at right angles on the left and right sides.
One side of the sheet metal strip grips the hook from below, whereas the other side surrounds the head like a hook in a longitudinal rib that also grips from below. Moreover, the engagement by the shape is further formed in the same manner.
Similarly, here again, purely shape-engaged coupling is a drawback, and this coupling embodies a fixation that does not last longer and, in addition, is neither reliable nor highly loadable.

Similarly, in another roof fixing according to Patent Document 4, one fixing system is described, and in this fixing system, the fixing with the under-roof structure via the upright longitudinal ribs is adjacent. The so-called pantile is made in such a way that the ends of the erect longitudinal ribs of the straw are surrounded by each other and a standing splice is formed. Clips are fixed so that the engagement in the engaged state due to this shape does not expand under load, and these clips perform a kind of clamping action.
At that time, it is a problem that this mode of fixing system does not sufficiently stabilize and fix the pantile (sheet metal strip). This is because this mode is fixed only at the upper end of the standing seaming, and the pantile can therefore be easily distorted by the various acting forces. At that time, the roof panel may be partially and significantly deformed.

The subject of the present invention is
Large surface roof coverings or walls made of metal for fixing flat roof elements, sheet metal plates or sheet metal strips that can be placed side by side on top of under-roof structures or under-wall structures. To provide a fixing system for the coating,
The fixation system is structurally easy to construct, consists of few members and can be assembled quickly, and the fixation system is suitable for high negative wind loads.

This problem is solved by the feature of claim 1 according to the present invention. A further purposeful configuration of the present invention is the subject of the subordinate claims.
Fixing systems according to the invention for large surface roof coverings or wall coverings made of metal roof two or optionally many, side-by-side, planar roof elements, sheet metal plates or strips. Suitable for fixing on a lower structure or a wall lower structure, wherein the roof element, sheet metal plate or sheet metal strip 1 is different, flat or corrugated. Alternatively, it can be formed as if contoured.
This fixation is performed inside the erect longitudinal ribs 2, and these longitudinal ribs are formed by the sheet metal legs 11 erecting laterally. These longitudinal ribs are advantageously bent at right angles, however, other angles (obtuse or acute) can be considered as well. The longitudinal ribs 2 are then parallel to or tilted from each other and extend over the covering and are formed distributed over the roof or wall covering.
According to the present invention, on the under-roof structure or under-wall structure, inside the erect longitudinal rib 2, longitudinally, consistently, or only occasionally (at the base). An extending T-shaped base strip 3 (referred to as an element) is arranged and fixed. It is possible that both horizontal legs of the T-shaped base strip 3 (or base element), referred to as the base leg 5, are positioned downward or upward.
In these T-shaped base strips 3, on the left and right sides, in the vertical legs of these T-shaped base strips 3, called the central leg 4, up to the foundation leg 5. , The recess 6 is formed. A specially formed protrusion 13 of the side sheet metal leg portion 11 of the roof element, the sheet metal plate or the sheet metal strip 1 is engaged in these recessed portions 6.
These preformed protrusions 13 generate shape engagement in the central leg 4 or in relation to the pressing plate 9 which can be placed on the central leg 4. These pressing plates 9 are usually arranged in a plurality of layers at predetermined intervals. However, similarly, these pressing plates can also be formed as consistent strip-shaped pressing plates 9.
These pressing plates 9 are fixed to the base strip head 7 in an engaged state by shape or, for example, screwed in a suitable structure and method. However, similarly, for a given roof covering, material structure integral coupling is also possible.
The pressing plates 9 are formed so that the pressing plates 9 cover the protruding portion 13 of the sheet metal leg portion 11 of the roof element, the sheet metal plate or the sheet metal strip 1 located side by side. .. This ensures that the durable, shape-engaged coupling is centered on the T-shaped base strip 3 (or, if arranged one by one, referred to as the base element). It is generated by using the leg portion 4 and the pressing plate 9.
At the upper end of the lateral sheet metal leg portion 11 projecting upward, the entire longitudinal rib is formed by being closed by the cover strip 12.

If the size and shape of the protrusion 13 in the sheet metal leg 11 corresponds to the size and shape of the recess 6 in the central leg 4 and the foundation leg 5, then a roof element, sheet metal plate or sheet metal strip. A particularly good, durable, permanent, shape-engaged coupling between the body 1 and the T-shaped base strip 3 or the T-shaped base element 3 is a large surface roof covering. Alternatively, it is achieved by the central leg 4 and the base leg 5 of this T-shaped base strip or this T-shaped base element in a fixing system according to the invention for wall coverings.
The dimensions and shape of the pressing plate 9 also advantageously correspond to the dimensions and shape of the protrusion 13.

It is significantly advantageous when both recesses 6 in the central leg 4 and the foundation leg 5 are formed symmetrically.
In that case, the roof element, sheet metal plate or sheet metal strip 1 is formed identically (and similarly symmetrically) on the left and right sides by the upright and prefabricated protrusions 13 and sheet metal legs 11. It is possible to do. This already provides significant time and cost advantages in the manufacture of preformed roof elements, sheet metal plates or sheet metal strips 1.
In addition, in that case, the assembly position is not preset, which, on the other hand, necessarily entails advantages when assembling the roof or wall in the field.

In a fixed system according to the invention for roof coverings or wall coverings on large surfaces, various shapes of recesses 6 and belonging protrusions 13 can be advantageously used.
Therefore, both recesses 6 in the central leg 4 and the foundation leg 5 have a dovetail or oval shape in cross section, taking into account the shape of the pressing plate 9 in the pressure region. Alternatively, it can be formed in a circular shape.

In a fixing system according to the invention for roof coverings or wall coverings on large surfaces, in addition, if the reinforcing rod 14 is placed within the protrusion 13 of the sheet metal leg 11, in a simple structure and manner, it is negative. The reliability of the wind load can be significantly improved. These reinforcing rods 14 are either pushed into the protrusions 13 from the side or already inserted in advance. Advantageously, the cross section of the reinforcing rod 14 is adapted to the cross section of the protrusion 13.
This, however, can cause the relatively thin-walled, thin-plate roof elements, sheet metal plates or sheet metal strips to deform due to the forces acting over time and lose their shape engagement. Being sexual is prevented. However, it is also possible to consider that these cross sections are different from each other as well. Thus, for example, a triangular or quadrangular cross section of the reinforcing rod 14 can be considered as well.
These reinforcing rods automatically generate force-engaged couplings that are not particularly dissociable. Further, the reinforcing rod 14 has the effect of significantly improving the stability of the entire roof between the longitudinal ribs 2. Within all roof panels, there is almost no more deformation.
This roof panel is practically, directly, mechanically fixed and tightened on the under-roof structure or under-wall structure, and permanently associated with the under-roof structure. Retain the position and shape of this roof panel. This is because the coupling of the engaged state by the shape cannot be bent and opened.

In a fixing system according to the invention for roof coverings or wall coverings on large surfaces, the dimensions and cross-sectional shape of the reinforcing rod 14 are exactly the same as the dimensions and cross-sectional shape of the protrusion 13 of the sheet metal legs 11 and the same. In addition, when adapted to the cross-sectional shape of the recess 6, the coupling of the engaged states by shape is the most reliable and most stable.

Instead of engaging state coupling with the base strip head 7 by the shape of the pressing plate 9, in a fixing system for roof coverings or wall coverings on large surfaces, at the central leg 4 or at this central leg. The head screw 10 in which the pressing plate 9 fixed on the top is charged to the base strip head 7 at an appropriate interval and at a predetermined interval according to each load in the same force-engaged state. It is possible to be screwed and fixed using.

For strength reasons, in a fixed system for large surface roof coverings or wall coverings, these T-shaped base strips 3 or these T-shaped base elements 3 alternate or pair with the under-roof structure. It is possible that the object or the under-wall structure is secured with a correspondingly sized base screw 8.

In fixing systems for roof coverings or wall coverings on large surfaces, it is advantageous if the T-shaped base strips 3 and / or pressing plates 9 are formed as molded rails.
These T-shaped base strips 3 or similarly the pressing plate 9 also have partial intermediate chambers as needed, or similarly for strength and stability reasons, the entire roof. It is possible that they are arranged consistently over the spread, i.e., extending without gaps.

In a fixing system for roof coverings or wall coverings on large surfaces, the cover strips 12 that are consistent on the longitudinal ribs 2 on the upper side are sheet metal legs for a secure seal against the effects of the weather, especially any humidity. It is connected to the portion 11 by using a folding joint portion in an engaged state depending on the shape.

These T-shaped base strips 3 or these T-shaped base elements 3 are pressing plates in a fixing system according to the invention for roof coverings or wall coverings of large surfaces for the formation of predetermined wider longitudinal ribs. It is possible that 9 and these positions are interchanged and arranged and are coupled to the under-roof structure or under-wall structure using a central penetrating fixing screw 15. ..

In a fixing system for large surface roof coverings or wall coverings, depending on the structural style and material of each roof covering, the reinforcing rod 14 is selectively made of special steel, aluminum, or similarly rubber. It can be made of various plastics, down to the material, or woven composites.

Additional reinforcement rods 14 may be equally effective if they are made of different materials in a fixing system for roof coverings or wall coverings on large surfaces.
For example, the plastic sleeve can compensate for the different expansions and frictions between the metal reinforcing rod 14 and the roof covering sheet metal.

In order to prevent the reinforcing rod 14 from slipping out of the protrusion 13 in this fixing system, especially in roof coverings or vertical wall coverings on steeply sloping surfaces, the reinforcing rods 14 are linear and threaded. , Or it is possible to have ridges 17 arranged in dots.
This causes the bite into the inner surface of the molded portion of each roofing material.

Similarly, in fixed systems for roof coverings or wall coverings on large surfaces, it is possible to pull a consistent rope into the protrusion 13 instead of the reinforcing rod 14 to be inserted.
These consistent ropes can be tightened at the ends, respectively, if necessary, and the entire roof panel is associated with this and is formed separately, separately distorted with the roof or wall structure. It can be obtained and fixed. Further, similarly, these ropes can be pulled in (stretched) under tension so that in such ropes they are re-expanded after relaxation of the cross section and the protrusions are spatially sufficient. Fill in.
Here, steel configurations and as well as other permanently weather resistant rope configurations are suitable. Thus, for example, the ropes can be made of plastic or carbon fiber, in which they can also be infiltrated with an additionally curable synthetic resin penetrant. Is.

The fixing system according to the present invention for large surface roof coverings or wall coverings made of metal with upright longitudinal ribs 2 is on and tilted on roofs with very different slopes and curves. Guarantees a secure, stable and windproof fixation of flat roof elements, sheet metal plates or sheet metal strips 1 that can be placed side by side on vertical or overhanging wall structures. In addition, it is completely sealed against all environmental influences.
This fixation system consists of a small amount of structurally distinct individual members, can be assembled quickly at low cost, and can be configured for extremely high, negative wind loads. In addition, considerable tension and shear forces during different large coatings, for example induced by temperature expansion, are compensated with high reliability and without damage.

The present invention will be described in detail below with reference to FIGS. 1 to 4 within one example.

According to the present invention, in a longitudinal rib 2 having a pair of threaded portions of a T-shaped base strip 3 on an under-roof structure or under-wall structure (not shown). A cross section of a fixed system. FIG. 3 is a view of a fixation system with a pushed-in reinforcement rod 14. FIG. 5 is a view of a fixing system having a specially formed screwed portion of a pressing plate 9 with a base strip head 7. A T-shaped base strip 3 that was pierced, screwed and placed on top, a protection section using a pair of reinforcing rods 14 and placed on top of these reinforcing rods. FIG. 6 is a wide, interchanged configuration diagram with a ridge 17.

In FIG. 1, symmetrical and paired with two base screws 8 of a T-shaped base strip 3 on an under-roof structure or under-wall structure not shown graphically. A cross section of an advantageous embodiment of a fixation system according to the invention within a longitudinal rib 2 having a state screwed portion is illustrated.
The base strip head 7, as the end of the central leg 4 of the T-shaped base strip 3, complements the coupling notch having the T-shaped undercut within the pressing plate 9. Similarly, it is formed in a T shape. At that time, the T-shaped base strip 3 having the wide upper beam of the T-shaped base strip is screwed downward onto the under-roof structure or the under-wall structure. ing. This wide upper beam forms the left and right basal legs 5, which are formed into a substantially semicircular shape. The central leg 4 is formed in a straight line, and the base strip head 7 is formed in a T shape.
Instead of a T-shaped coupling solution between the base strip head 7 and the pressing plate 9, for example a dovetail joint may be configured as well. This has an advantage in assembling. This is because the pressing plate 9 is pushed from the side through the base strip head 7. Similarly, in the pressing plate 9, a substantially semicircular recess is formed downward on the left side and the right side of the joint notch. In this way, a substantially oval recess 6 is formed.
Two preformed roof elements, a sheet metal plate or a sheet metal strip, after the T-shaped base strip 3 is secured onto the under-roof structure or under-wall structure using the base screw 8. 1 is inserted into the T-shaped base strip 3 on the left and right sides. These roof elements, sheet metal plates or sheet metal strips 1 are provided with substantially oval protrusions 13, which are formed here following a double bend.
This means that both the left and right roof elements, the sheet metal plate or the sheet metal strip 1, both flat, rest as entirely as possible on the under-roof or under-wall structures. It is advantageous because it can be placed.

Since such a style of roof covering is laid over the entire underside structure, it is usually a beam structure, a carrier structure or a strut structure. The shape and position of the protrusions 13 correspond to the dimensions and cross section of the recess 6 in the dimensions and cross section of these protrusions. The roof element, the sheet metal plate or the sheet metal strip 1 moves laterally upward to the sheet metal legs 11 standing at right angles.
When these roof elements, sheet metal plates or sheet metal strips 1 are inserted into the T-shaped base strips 3 or base elements, the pressing plate 9 is pushed in from the side in a suitable structure and manner.
If these roof elements, sheet metal plates or sheet metal strips 1 are fixed here inside the longitudinal ribs 2, then finally on the upper side, at the upper end of the sheet metal legs 11, a consistent cover. The strips 12 are assembled using the creases. This is done mechanically by a suitable folding machine. Along with this, the longitudinal rib 2 is climatically closed and a permanent, mechanically secure fixation is formed on the under-roof structure or the under-wall structure. ing.

FIG. 2 shows the same modal configuration of a fixed system for large surface roof coverings or wall coverings made of metal, as already described above in FIG. However, here, the reinforcing rod 14 is additionally inserted or pushed into the protrusion 13 on the left side and the right side. Inserting or pushing the reinforcing rod 14 on only one side may be sufficient for a given configuration of the roof covering.
These reinforcing rods 14 are here configured in a substantially oval shape and, in their dimensions and cross section, correspond to a roof element, a sheet metal plate or a protrusion 13 of a sheet metal strip 1. This significantly improves the strength of this structure.
Depending on the respective dimensional settings of these reinforcing rods 14, mechanical stability is on the underside, stable roof in such a way that a correspondingly larger or smaller cross section is pre-inserted or pushed back. It can be adjusted as appropriate within the area of the underside structure or the underside structure of the wall. Along with this, the reliability against negative wind load is significantly improved.
Advantageously, the cross section of the reinforcing rod is adapted to the cross section of the protrusion 13. This, however, can cause the relatively thin-walled, thin-plate roof elements, sheet metal plates or sheet metal strips to deform due to the forces acting over time and lose their shape engagement. Being sexual is prevented. These reinforcing rods 14 create a permanent bond of force engagement directly within the area of the flat roof panel (pantile straw).

FIG. 3 shows a planar roof element that can be placed side by side in one configuration with a threaded portion of a pressing plate 9 with a base strip head 7 specially formed for screwing. Demonstrates a fixing system for roof coverings or wall coverings of large surfaces made of metal for fixing a sheet metal plate or sheet metal strip 1. All other structural details correspond to the technical configurations already described under FIG.
The base strip head 7 is here specially reinforced and expanded to form a hollow chamber on the inside, so that the pressing plate 9 is here, for example, simply by itself. It is connected to the T-shaped base strip 3 via the central leg 4 by the head screw 10 to be threaded.
The base strips, on the other hand, are also secured to a under-roof or under-wall structure (not shown) by two self-threading base screws 8 in pairs. This advantageous configuration allows for faster on-site assembly. This is because the pressing plate 9 does not need to be pushed in from one side, but rather can be placed from above and screwed.

In FIG. 4, a wider configuration of a fixed system for a large surface roof covering or wall covering is shown.
At that time, the T-shaped base strip 3 and the pressing plate 9 are arranged interchangeably with respect to the arrangement already described, that is, the pressing plate 9 is directly on the lower side and on the lower side of the roof. Positioned and placed on top of the structure or under-wall structure.
The preformed roof element, sheet metal plate or sheet metal strip 1 is then placed with the already pre-inserted reinforcing rod 14, and then the T-shaped base strip 3 is inserted from above and this. The T-shaped base strip, including the pressing plate 9 placed beneath it, is screwed to the under-roof or under-wall structure by the penetrating fixing screws 15.
To improve the stability of this wide roof covering configuration, two reinforcing rods 14 are inserted here again, on the left and right sides. These reinforcing rods 14 can also be pushed in after the fact, however, usually before the insertion and fixing of the T-shaped base strip 3, the roof element, sheet metal plate or sheet metal strip 1 It is inserted into the protrusion 13. Along with this, negative wind loads or other acting forces do not cause any deformation of the roof panels and pantiles.
Here, separate ridges 17 are placed on the reinforcing rod 14 made of two materials, which allow the ridges to bite into the material of the roof element, sheet metal plate or sheet metal strip 1. The slip position of these reinforcing rods 14 is permanently prevented from shifting.

These technical solutions described above are, first of all,
A large surface roof covering made of metal or for fixing a planar roof element, sheet metal plate or sheet metal strip 1 that can be arranged side by side on an under-roof structure or under-wall structure. It can be used as a fixing system for wall coverings.
