EA025763B1 - Profile sheet and joint between profile sheets - Google Patents

Abstract

The present invention refers to joints between profile sheets (1) used for roofing, the joints being perpendicular to the roof ridge, and to providing support in the ridge direction for the profile sheets. The invention is based on providing the profile sheet (1) comprising, as viewed from above, a designed transverse profiling (7), with such a shape of the longitudinal profiling (4) at the lateral edges (2, 3) of the profile sheet (1), which enables overlapping profile sheets adjacent to each other in the ridge direction, in such a way, that the folds (12) of the longitudinal profiling (4) overlap only partly. Thus a larger effective width is achieved as well as an improved support in the ridge direction of adjacent profile sheets (1).

Description

The invention relates to the design of joints passing in the direction of the lateral edges of the profile sheets used as roofing material, and to support the profile sheets in the direction of the roof ridge. In particular, the invention relates to profiled sheets that are made of sheet metal and according to the preamble of claim 1 of the formula have a certain configuration in the direction of the roof ridge, i.e. profile sheets are profiled in the transverse direction. In addition, the invention relates to the design of the joint between the profile sheets according to the preamble of claim 12 of the formula.

State of the art

Profile sheets used as roofing material almost exclusively have a configuration perpendicular to the direction of the roof ridge, which in this context is called a longitudinal profile. It serves as a drain, a stiffening element of the shape of the profile sheet, and / or docking means in the junction between the profile sheets adjacent to each other in the direction of the roof ridge. Such a longitudinal profile often turns the profile sheet into a so-called corrugated sheet containing a plurality of folds that extend in a direction perpendicular to the roof ridge. Profile sheets are often made of rolled steel tape of standard width. The effective width achieved in this case depends on the selected profile configuration and on the overlap between adjacent profile sheets.

It is well known that the overlap of profile sheets used for roofing adjacent to each other in the direction of the roof ridge is made so that the side edges of the profile sheets adjacent to each other in the direction of the roof ridge overlap at least by an amount equal to one bend width. In other words, the extreme folds of adjacent profile sheets are located one on top of the other, i.e. they overlap, while forming a support in the direction of the ridge of the roof between adjacent profile sheets and a simple joint between these profile sheets. A disadvantage of such a known solution regarding the achievable effective width is that the overlapping sheet material is used in the joint. In addition, known sheets and joints cause abrasion in the overlap area of two joined sheets.

A profile sheet with a transverse profile is also well known, while the transverse profile has such a shape that when viewed from above on the roofing plane, a straight line is formed in the direction of the roof ridge, i.e. the operation of forming the profile sheet does not contain profiling in the direction of the edge when viewed from above on the roofing plane. In this known technology, an attempt has been made to eliminate this drawback by obtaining a joint between the profile sheets adjacent to each other in the direction of the roof ridge so that the profile sheets overlap less than half the bend width. However, the disadvantage of this known technology is that with this solution, a weak support of the profile sheets in the direction of the roof ridge is obtained, since the connections between adjacent profile sheets create a small supporting effect. Thus, the support of the profile sheets in the direction of the roof ridge is based solely on the shape of the longitudinal profile and on the support created by the fixing screws. Such weak support of the profile sheet causes abrasive wear in the joint area.

SUMMARY OF THE INVENTION

The objective of the invention is to eliminate the disadvantages of the known technical solutions and providing a profile sheet and a junction between the profile sheets, having a minimum consumption of sheet material for overlapping and at the same time creating significant support in the direction of the roof ridge for the profile sheets in the joints between the profile sheets.

The objective of the invention is solved using the profile sheet and the design of the joint between the profile sheets according to the independent claims. 1 and 8 of the claims. Preferred embodiments of the invention are presented as objects of the dependent claims.

The invention is based on the provision of a specific configuration of the longitudinal profile in the region of the lateral edges of the profile sheet on the profile sheet having a transverse profile when viewed from above on the roofing plane, while this configuration provides such an overlap of the profile sheets adjacent to each other in the direction of the roof ridge, in which bends longitudinal profiles overlap only slightly. This provides increased effective width and reinforced support of adjacent profile sheets in the direction of the roof ridge.

The profile sheet forming the roofing plane contains the upper and lower edges, as well as the first and second side edges. In addition, the profile sheet according to the present invention contains a longitudinal profile extending in the direction from the first side edge to the second side edge of the profile sheet. The longitudinal profile contains bends of the first type having first and second transition parts and a first protrusion between said first and second transition parts. The longitudinal profile of the profile sheet at the second lateral edge in the lateral direction of the profile sheet ends essentially with a fold of the first type. The longitudinal profile at the first lateral edge in the lateral direction of the profile sheet ends essentially with a fold of the second type. The fold of the second type of the first lateral edge comprises a second fold protrusion and a third transition portion.

In addition, the fold of the second type is equipped with a drain. The drain is made on the part of the second protrusion of the fold of the second type or between the third transitional part and the second protrusion of the fold of the second type. Two adjacent profile sheets overlap in the region of the edge to form a joint, wherein the fold of the first type of the second side edge of the profile sheet is located over the fold of the second type of the first side edge of the other profile sheet.

Unexpectedly, it turned out that a sufficient level of resistance to weathering of the joint between adjacent profile sheets is provided with partial overlap, if the profile sheets have a structure according to the invention. Due to the shape of the transverse profile of the profile sheet, the joint between adjacent overlapping profile sheets provides excellent support for the profile sheets in the direction of the roof ridge, while the potential movement of the joint perpendicular to the roof ridge is minimized, and the overlap of the joint is reduced. In addition, the cross-sectional shape of the overlapping profile sheets provides excellent fastening during installation of adjacent profile sheets. The bend shape of the second type with the third transitional part and the second protrusion provides an increase in the effective width of the profile sheet, as well as the edge region with good support in the overlap area. The gutter, made on the bend of the second type of the first side edge, creates a combined support effect in the joint area. As indicated above, the movement of adjacent profile sheets with respect to each other in the joint area is minimized, while the abrasive wear of the overlapped profile sheets is also minimized.

According to the invention, the technical effective width of the profile sheets can be increased by the same width of the steel strip, which as a technical solution reduces the amount of sheet material used for the roof surface.

Information confirming the possibility of carrying out the invention

In FIG. 1 shows a profile sheet 1 according to the invention, comprising a longitudinal profile 4, which includes bends 12 of the first type extending in the direction from the first 2 side edges to the second 3 side edges, and a transverse profile 7 having a certain configuration when viewed from above on the roofing plane 9, which runs in the direction of the upper 5 and lower 6 edges. In other words, the transverse profile 7 is not straight when viewed from above on the roofing plane 9, but has, for example, a wavy shape. The profile sheet according to the invention is made of sheet metal, preferably from a sheet steel with a thickness of 0.4-1 mm coated.

A preferred longitudinal profile shape is shown in FIG. 5, where the longitudinal profile 4 contains upwardly directed bends 12 of the first type, which end laterally T

- 2,025,763 profile sheets on the transitional parts 17A, 17b folds. Each fold 12 of the first type comprises a first transition part 17a and a second transition part 17b and a first protrusion 18 between said first 17a and second 17b transition parts. The first protrusion is substantially flat or only slightly curved, as shown in FIG. 4. In this case, a substantially flat or only slightly curved first protrusion extends in the direction of the roofing plane 9. The first 17a and second 17b transitional parts and the essentially flat first protrusion 18 form a shape corresponding to the shape of the roof tile. The longitudinal profile extends in the direction of the first 2 and second 3 lateral edges. The folds of the first type of longitudinal profile are preferably identical in shape except for the first 2 and second 3 lateral edges of the profile sheet. The bends 12 of the first type of longitudinal profile end in the lateral direction T of the profile sheet in a certain way on the first and second side edges of the profile sheets, since the most extreme folds form a junction 15 between the profile sheets adjacent to each other in the direction of the roof ridge.

At the junction 15 between the profile sheets 1 adjacent to each other in the direction of the roof ridge, which are shown in FIG. 4, it can be seen that on the first 2 and second 3 lateral edges of the profile sheet, the longitudinal profile in the lateral direction T of the profile sheet ends so that on the second side edge 3, the fold of the longitudinal profile is complete and contains the first protrusion 18 of the fold 12 of the first type and the first 17a and the second 17b transition portions directed downward from the first protrusion 18 of the fold 12 of the first type, wherein the first transition portion 17a preferably forms a second side edge 3 of the profile sheet.

The fold 12 of the first type of longitudinal profile at the first lateral edge 2 is a fold of the second type, i.e., the fold of the second type is partial. In other words, the fold of the second type 13 comprises a second protrusion 19 of the fold of the first type 12 and the third transition portion 17c of the fold 12 of the first type, but not the first 17a and the second transition parts 17b. This third transition portion 17c of the fold of the first type 12, located on the first side edge 2, does not form the first side edge 2 of the profile sheet, while the first side edge 2 is formed by the second protrusion 19 of the fold 12 of the first type.

The width \ Y2 of the bend 13 of the second type is preferably less than half the width \ Y1 of the bend 12 of the first type, i.e., ^ 2 <(^ 1/2), and according to the invention, an increased effective width is provided for the same web width. In other words, at the junction 15 between the profile sheets according to the invention, the bend 13 of the second type does not extend beyond the center line H of the bend 12 of the first type. As shown in FIG. 4, the width of the portion of the second protrusion 19 of the bend 13 of the second type may be less than half the width of the first protrusion 18 of the bend 12 of the first type.

The fold 13 of the second type at the first lateral edge 2 preferably comprises a drain 14, which in a controlled manner collects water rising due to the capillary effect. Most preferably, the drain 14 is formed in the fold 13 of the second type, and the drain 14 will not be located directly on the edge of the profile sheet, as shown in FIG. 4.

In FIG. 3 shows an embodiment of a fold 13 of a second type of a profile sheet according to the invention, in the fold of the second type of which a drain 14 is made. In this embodiment, the fold 13 of the second type ends with a drain 14. In the junction between the profile sheets, the third transition portion 17c of the fold 13 of the second type will be tightly pressed to the bottom surface of the fold 12 of the first type of another profile sheet.

As indicated above, the drain 14 extends in a direction substantially parallel to the first lateral edge 2. The drain 14 can be made between the first lateral edge 2 and the third transition portion 17c of the fold 13 of the second type.

In one embodiment, a drain 14 is formed in a second protrusion 19 of a fold 13 of a second type, as shown in FIG. 3. In an alternative embodiment, a drain 14 is formed between the second protrusion 19 and the third transition portion 17c of the fold 13 of the second type, i.e. in the corner where the third transition portion 17c transitions into the second protrusion 19, as shown in FIG. 4. Alternatively, the drain can also be made on the third transitional part 17c, wherein the fold of the second type 13 contains a section rising upward from the drain 14.

The gutter 14, made on the bend 13 of the second type, and, in particular, on the second protrusion or between the second protrusion 19 and the third transitional part 17c, increases the rigidity of the second protrusion of the bend 13 of the second type and simultaneously collects capillary water that rises between the overlapped profile sheets . Thus, the drain 14 can be used to increase the rigidity of the bend 12 of the second type and, in particular, the second protrusion 19 of the bend 12 of the second type.

At the junction 15 between the profile sheets, the profile sheets 1 according to the invention form an overlap over an area of less than half the width of the first type of fold (^ 1). wherein the fold 12 of the first type on the second lateral edge 3 of the first profile sheet 1 is superimposed on top of essentially the fold 13 of the second type on the first edge of the second profile sheet 1. In other words, the overlap is less than (^ 1/2) to obtain the joint 15 having a width less than half the width \ Y1 of the fold 12 of the first type.

In FIG. 2 shows a detailed view of the shape of the transverse profile of the profile sheet 1 according to the invention, while this shape has a certain configuration when viewed from above on the cropped plane 9. In other words, in the direction of the upper 5 and lower 6 edges when viewed from above on the roofing plane, the shape is transverse profile 7 is not straightforward, but partially has some other shape in the direction of the first 2 and second 3 side edges, in particular a wavy or angular shape. In other words, the wave-like shape of the transverse profile 7 or, preferably, the wave-like shape of the transverse profile 7, comprising a portion 16 substantially parallel to the first 2 and second 3 side edges, will serve as a support for the pairwise overlapping profile sheets in the direction of the roof ridge. A support reaction appears at the junction between the profile sheets 1 adjacent to each other in the direction of the roof ridge when two or more profile sheets 1 are joined together in the direction of the roof ridge. Zga support compensates for the weakening of the support in the direction of the roof ridge, caused by a partial overlap between the profile sheets adjacent to each other in the direction of the roof ridge. Most preferably, the portion 16 substantially parallel to the first and second lateral edges of the transverse profile is located on the first 17a and second 17b transition portions of the folds 12 of the first type of longitudinal profile. Most preferably, the portion 16 parallel to the first and second lateral edges is straight when viewed from above on the roofing plane 9 and comprises a flat surface substantially perpendicular to the roofing plane 9 to further strengthen the support in the direction of the roof ridge. In the case when several profile sheets 1 are connected one after another in a direction perpendicular to the direction of the roof ridge, overlapping so that the profile sheets 1 overlap in the area between the upper edge 5 and the first transverse profile 7 in the direction of the first 2 and second 3 side edges, counting from the upper edge of the lower profile sheet, between the connected profile sheets a lock connection is formed, which additionally prevents the movement of the profile sheet in the direction of the roof ridge.

The term transverse profile means a profile or configuration in the direction of the upper and lower edges of the profile sheet. The transverse profile preferably contains one or more terrace steps or simply steps, as shown in the figures. The plane formed by the steps is preferably substantially perpendicular to the roof surface 9. The shape of the transverse profile 7 is continuous over the entire roof surface 9, i.e. terrace steps are identical. According to the invention, one or more elements of the transverse profile 7 can be located between the upper 5 and lower 6 edges 7. The lower edge 6 of the profile sheet preferably has a configuration that corresponds in shape to the transverse profile 7, i.e., the terrace step, while using its lower edge 6 can be connected to the first transverse profile 7, i.e. with a terrace step counted from the upper edge of the profile sheet installed below the previous profile sheet.

Roofing plane 9 of the roof means the surface of the profile sheet 1, which has a slope, for example from the ridge of the roof in the direction of the roof slope. The upper 5 and lower 6 edges of the profile sheet mean edges parallel to the roof ridge or roof surface. The first 2 and second 3 side edges of the profile sheet 1 are edges extending at right angles to the roof ridge.

Profile means a configuration that is independent of the manufacturing method. The longitudinal profile is preferably obtained by the roll forming method, and the transverse profile by the pressing method.

The configuration of the bends 12 of the first type, containing the first 17a and second 17b transitional parts and essentially flat or only slightly curved first protrusion 18, allows to obtain durable and tight joints 15 between adjacent profile sheets. The fold 13 of the second type according to the present invention provides an efficient use of the material of the profile sheet. In addition, providing a drain 14 on the fold 13 of the second type increases the rigidity of the fold 13 of the second type and the junction 15 between adjacent profile sheets. The fold 13 of the second type with a drain, together with the configurations of the folds 12 of the first type and folds 13 of the second type, provides a joint in which abrasion between the overlapping profile sheets is minimized. In particular, the configuration of the fold of the first type 12 and the fold of the second type 13 and the gutter prevent or at least reduce friction between the first side edge 2 and the lower side of the fold 12 of the first type of another profile sheet in the joint 15.

For specialists in the art it is obvious that with the development of technology the main idea of the invention can be used in many different ways. Thus, the invention and its embodiments are not limited to the examples described above, but may vary within the scope of the invention, which is defined by the claims.
