Description

The invention relates to a cover for walls, z. As for masonry, especially for the top of the masonry, wherein the cover on the wall or the masonry by means of a wall or the masonry crown cross arch is attachable or attachable. Moreover, the invention relates to methods for producing the cover

The building regulations stipulate that the walls, which are still under construction, must be covered and protected against penetrating moisture. Protection against wind and sun is also desirable. Ingress of water can damage the durability of a wall. Especially when freshly masonry walls get damp again on the mortar, it can cause cracks in the masonry later on. Such cracks must be repaired consuming as structural damage. Other wall constructions such as clam-shell wooden walls or concrete walls must also be protected from excessive wetting with rain or moisture during construction. In the past, sometimes very elaborate slatted and foil constructions were provisionally provided on the construction site, and these slipped over the masonry crowns. Although such devices provide sufficient protection against the weather, but can be lifted in strong winds from their position.

To avoid these makeshift and can be created only with great effort constructions proposes the DE 199 51 457 A1 a cover which is in cross-section substantially U-shaped, wherein the web of the U's the mural crown overlaps. Such prefabricated as a kit cover can be mounted quickly even in case of unforeseen weather changes and thus protect the wall safely from the weather. Such a standardized cover is kept in different versions according to the wall thickness. So that no water collects on the cover, the web of the U can be provided with a rounding in the prior art cover. It is proposed to provide a separation between the U-shaped profile and the cover. The U-shaped arch profile thus serves as a holding element similar to a frame that receives the cover. Alternatively, the use of a durchführgängigen U-shaped profile is proposed. Connecting elements connect to the joints of the U-shaped profile parts in such a way that the U-shaped profiles protect the wall crown completely without gaps. To save space, the holding elements and the cover can be stored separately.

A disadvantage of this known cover that it must be assembled from the individual parts of the construction kit just described on the site. The items and their production are also relatively expensive.

The DE 32 26 930 A1 discloses a device for preventing damage to a door lining during the interior fitting phase. A sheet of cardboard is beaten around a door chuck and fixed by means of two bending elastic, one-piece and curved clamps, which are formed connected to the cardboard

The present invention has therefore set itself the task of providing a cover that is cheaper to manufacture and easier to assemble and allows easy slope mounting, and requires less space on site. Besides that is It is an object of the invention to provide a method for producing the cover.

This object is achieved in a cover in that the cover is designed as a bendy fabric by the meter and can be attached or fastened to the wall by means of a crown over the arch, the flexible fabric by the meter has at intervals bending elastic, omega-shaped, one-piece, provided with a scaling clamping arcs , wherein the clamping arches are formed undetachably connected to the bendable meter goods, at least some clamping arcs have a distance from each other, which is formed larger than the arc length of a clamping arc, and at least one clamping sheet is formed translatable by another clamping arch, and that the cover on an open Hollow section part can be arranged as an assembly and / or storage aid. The use of bend-soft meterware with connected clamping arches makes construction and usability of the cover much easier. Due to the special shape of the gripping arcs in the style of a Greek Omega, whereby this form could also be described as an open "O", the entire arch becomes particularly elastic. From the term omega-shaped according to the invention, a web is detected, which has no exact circular segment-like curve, but is sharpened or flatter shaped and / or whose free legs have no exact circular segment-like curves. The free legs of the clamping arches nestle with a suitable design of the bracket at least in places on the side walls of the wall, but preferably almost over its entire length to achieve the strongest possible frictional engagement. The distances of the clamping arches are bridged by bendy meter goods made of plastic film, fabric or the like according to light-resistant, tear-resistant and waterproof material that is welded, glued or sewn to the clamping arches.

The omega-shaped clamping arches can be formed from spring band steel, the thickness and width of which is dimensioned according to the desired clamping strength. By suitable choice and dimensioning so the bending line of the clamping arc can be adapted to the cross-sectional profile of the wall. With great advantage, the clamping arches have an internal width, which allows use for at least two of the standardized wall thicknesses. As a result, a separate devices need not be kept ready for each of the standard widths.

With appropriate dimensioning, can be used instead of the spring steel and plastic, in particular fiber reinforced plastic, whose fibers consist for example of glass or carbon and which is thermoplastically sprayable or extrudable in the appropriate form. Such a plastic clamping sheet is as well as one made of spring steel with a scaling to allow easy slope assembly of several interconnected cover with.

It is provided according to the invention that the clamping arches are permanently connected to the bendy meter goods. This can be done for example in the manufacturing process by welding by the meter and Klemmbogen. Such a design has the advantage of less number of components and thus simplified storage.

It is advantageously provided that at least some clamping arcs have a spacing from each other that is greater than the arc length of a clamping arch. In this way, the cover at the ends of the wall crown can be guided around both horizontal and vertical corners and easily secured by connecting two adjacent clamping sheet ends. In this case, the nail openings of the two adjacent clamping arches are preferably brought to coincide with vertical corners and together by means of a nail or a bracket against storm secured. In the case of horizontal corners or horizontal / vertical corners, such as wall angles with 90 ° or another included angle, stepped masonry, the distance between two clamping arches must be selected correspondingly larger. Advantageously, it is further provided that the clamping arches are designed to be translatable to one another. In this way, a secure continuation of the wall covering over indefinite lengths is possible with great advantage, since the last bracket of a wall covering segment with the first bracket of the follower element is translatable.

In an embodiment of the invention, it is provided that at least some clamping arches are detachably connected to the bendy piece goods. In this way, a simple adaptation of the device to a variety of masonry is achieved with great advantage. For larger openings so a clamp arch can be removed to have a longer stretch of flexible meter goods available. According to the invention, a self-made clamping arch can be placed after laying the cover on a wall between two integrally connected with the bendable piece goods Klemmbögen to achieve at this point a firmer connection of masonry and cover.

The frictional assembly of the cover can be secured by a positive connection when the cover and / or the clamping arches have nail openings. After positioning the cover then nails or wall brackets are driven through the openings in the wall, which secure the cover in position for a long time and in strong winds. Here, the nail openings are provided such that they meet the requirements of the wall geometry satisfy, for example in the form of multiple nail openings under or next to each other.

Advantageously, the cover has a reinforcement, which is formed, for example, in the form of a welded or extruded with the film of the cover network, reinforced by type pressure-resistant hoses. The reinforcement thus gives the cover a crack resistance which makes it possible to use the cover for a long time under rough construction site conditions. This reinforcement can according to the invention also consist of a material with high tensile strength, which has a certain restoring force, so that the device according to the invention automatically stretches and contracts. This design also serves better handling, storage and increases the reliability The reinforcement can therefore have stretchable reinforcing threads, with at least some reinforcing threads in the flexible material overlap in their longitudinal extent, so that the greatest possible restoring force results without transverse pulling forces. According to the invention, the flexible fabric by the meter may also have a different structure, provided that it has a high elasticity while at the same time having an automatic restoring force.

If tensile elements are provided in the region of the edges of the cover, the lower edge can be additionally secured with the cover. For example, such tension elements may consist of elastic bands which are guided through the nail openings or openings provided specifically for these tension elements. The ends of these tension elements can in turn be secured to nails or brackets.

In order to have the cover at hand at all times and to store it with a small footprint, it is provided that the cover is arranged on an open hollow profile part as an assembly and / or storage aid. As such a hollow profile part may serve a slotted tube on which the cover is pushed under wrinkling. If the cover is additionally excluded in this position in an outer solid protective cover, it can hardly be damaged when not in use. For the assembly will the hollow profile part, which is also formed correspondingly elastic, placed on the crown of the wall and attached one end of the cover to the wall. The hollow profile part can then be pulled over the entire wall crown, wherein the cover is then pulled taut from the hollow profile part. In this way, the cover can quickly bring in their desired position to protect the wall crown from the weather.

The cover can be manufactured particularly cost-effectively, if the cover is designed to be produced by means of a continuous process.

If at least one free end of a cover is covered by a hollow profile, an automatic unfolding is prevented with the simplest means, thus enabling secure storage.

A transport container, which forms no part of the invention, which is also used for storage, has with great advantage in its interior at least two open hollow profiles such that they each engage around a free end of a cover.

The process task for producing a generic cover for walls is achieved in that the cover is extruded as a tube and wrapped in or after extrusion at regular intervals of, preferably closed, clamping sheets and connected to these and the tube is then opened in the longitudinal direction. The cover is made in a known manner by blow molding an extruded tube in the desired dimension. Concentric to the hose, the clamping arches are supplied. These are initially preferably closed, so that the inflated inner tube during inflation against the clamping arches applies. The extruded and possibly reinforced foil of the tube is, for example, by appropriate gluing or welding with the clamping arches connected. After a cut in the longitudinal direction of the tube, which is also feasible with two spaced apart knives for the separation of a piece of the cross-sectional profile, then the cover is separated. Depending on the desired length, this finished product can then be separated and used as a cover on construction sites. Before, depending on the desired design, the cover thus produced can be equipped with nail openings or additional tension elements.

In the FIG. 1 shown cover 1 consists of the meterware 5, for example, a transparent film or tarpaulin, which is preferably reinforced by a network or by elastic threads, and at regular intervals with her firmly connected clamping arches 6 has. The clamping arches have a distance of about 70 cm to each other, this distance corresponds to a mean stress state of the stretchable reinforced film 5. The meterware 5 with clamping arches 6 overlaps the Wall crest 3 of the wall 2, so that moisture caused by weather no longer has access to the wall crown 3. At the end 14 of the wall, the cover 1 is wrapped around the end 14 of the wall crest, so that the end bend 15 lies in a horizontal plane. The nail openings 7 of the end bow 15 and its adjacent clamping arc 6 are meanwhile brought to coincidence and held by a clamp, not shown. The cover 1 forms folds 16 at the end of the wall crown 3. In the remaining area, the cover 1 is stretched substantially taut, so that the sheets 6 have a regular spacing 9, which corresponds approximately to the arc length 10 of the clamping sheet 6. In the area of the edges 11 of the cover 1, additional tension elements 12 are guided through the nail openings 7, which fix the edge 11 of the cover 1 to the surface of the wall 2 in a tautly elastic manner. The ends of the tension elements are in turn attached to unillustrated clamps or nails. The tension elements can also have corresponding tensioning elements for their tension or themselves consist of an elastic material. According to the invention, it is provided that individual, loose clamping brackets 6 can be subsequently clipped on at desired locations as a structural clamp for reinforcing the local frictional connection. The clamping arches lie over as large a distance as possible of their free legs 14 on the masonry.

FIG. 2 making a section according to section lines II-II in FIG. 1 represents shows clearly how the omega-shaped clamping sheet conforms to the surface of the wall 2 due to its elastic bending. Due to the masonry crown 3 following curvature of the clamping sheet 6 incident rain can flow off to the side. It is collected by the groove forming free ends of the omega-shaped clamping arc, so that the free ends act as a gutter with appropriate slope mounting, so as to protect vertically deeper and uncovered masonry from herring rainwater. The deepest or end point of this gutter according to the invention, for example, freely over Protruding masonry end, so that the collected and forwarded water is discharged without contact to the wall.

FIG. 3 The formation of folds 16, the individual clamping arches 6 are held close together on the hollow profile 13, wherein the tension elements 12 can form loosely straps.

In FIG. 4 who make a section according to IV-IV FIG. 3a shows, it can be seen that the hollow profile 13 is open in the longitudinal direction and has a slot 17. The edges of the hollow profile 13 at the slot 17 are bent inwardly to form slide rails, which can better slide on the surface of the wall 2. To bring the cover 1 in its position on the wall crown 3, the hollow section 13 with slot 17 is opened so far elastically that it can be slipped over the wall crown 3 so that it overlaps the wall crown 3. After removal of the first clamping sheet and its attachment to the wall, for example by means of nails, the hollow profile 13 can be slidably pulled along the wall crown 3, so that clamping sheet can be deducted after clamping sheet in a strained shape of the cover 1 of the hollow section 13, to Also, the last clamping sheet has left its position from the hollow section 13. If the length of the cover produced in this way is insufficient, the next cover 1 is brought in an analogous manner into its position on the wall crown of the wall 2 with suitable covering. The cover according to the invention can thus be produced particularly cost-effectively continuously and, in the event of weather changes, can be used quickly to cover the wall crest 3. Once the cover 1 is no longer needed, the hollow section 13 is set after removal of the wall clamps or nails, not shown for attachment of the cover 1 again on the wall crown 3 across and moved in the reverse direction on her, the clamping arches 6 back to the hollow section 13 can be pushed. So that the clamping arches do not slip over the hollow section 13, thorn-like stops are provided at one end of the hollow profile 13, so that the elastic bending property of the hollow section 13, for example by a flange is not affected.

In Fig. 5 an arrangement of covers 1 is shown in stacks 21 in a transport container 22, in which the free ends of the individual segments of a stack 20 advantageously provided with open hollow sections 19 as edge protection and are otherwise without guidance. These hollow sections 19 are firmly connected to the bottom of the transport and storage box 20, they serve as a guide for the stack, which can be so easy to unpack and unpack. Within a transport box 20 according to the invention, for example, five covers are arranged to each other so that in each case one of its free ends protrudes into the interior of another segment. In this way, the hollow profiles 19 associated with a stack 21 also give other stacks 21 a guide. It is also conceivable to arrange the covers arranged on hollow profiles 13 in the transport and storage box 20 in the correspondingly adapted hollow profiles 19. Regardless of the form of storage comprises a cover between 5 and 50 with bend-soft meter goods 5 connected clamping arches 6, so that the cover for the masonry crowns of a construction site as possible in a transport and storage box 20 are kept.
