Sandwich element equipped with rain gutter

Description

[0001] The invention relates to a sandwich element equipped with a rain gutter.

[0002] Sandwich elements, sandwich panels, sandwich boards, or composite panels (these terms are used synonymously within the scope of this disclosure) are prefabricated insulating structural elements for the construction industry, used in the manufacture of roofs or walls. Examples of applications include lightweight halls in industrial building construction, roofs for residential buildings, and also insulating panels for soundproofing or insulation in drywall construction.

[0003] Sandwich panels of this type consist of several layers, usually two thin outer layers forming an inner and outer shell, and an insulating core inserted between them. The individual layers are firmly bonded together, typically by adhesive. The outer shell is most often made of galvanized steel or aluminum. The inner shell can be made of galvanized or plastic-coated steel, thin aluminum sheet, stainless steel, or GRP (glass fiber reinforced plastic). The core is usually made of an insulating material such as polyurethane (PU), polyisocyanurate (PIR), or mineral wool. Bonding the outer and inner shells to the core makes the panels more resistant to bending or breaking, allows for larger spans, and protects the core, which is relatively softer than the outer and inner shells, from external influences.

[0004] Sandwich elements, sandwich panels, or sandwich boards are available with varying core thicknesses. The outer and inner layers can be designed with spaced, parallel high ribs and interspersed low ribs, similar to trapezoidal sheet metal, and / or with shallow grooves or ribs for dimensional stability. The cavities formed by the high ribs or grooves are typically filled with the core material.

[0005] The core material is typically exposed at the outer edges of sandwich panels. When several sandwich panels are laid side by side, these areas are covered on the outside, but not at the outer edges of a composite structure. These areas are either coated with a waterproof paint or fitted with a flashing or drip edge, for example, in the area of ​​the lower roof overhang, i.e., the eaves or end area. The flashing or drip edge also prevents animals or larger pests from accessing the softer core material.

[0006] The advantage of sandwich panels—namely, the short installation time, since the roof membrane, insulation, and interior cladding are installed and attached to a supporting structure in a single step—is somewhat diminished by the installation of the flashing and eaves, as their attachment is relatively time-consuming. Particularly in the area of ​​the roof gutter connection, covering the core at the edge of the sandwich panels is crucial for draining water flowing from the top and protecting the core material, and this requires more installation effort. Another disadvantage is that installing the flashing and eaves sometimes requires drilling through the outer layers, which can compromise the watertightness in this area or necessitate complex sealing measures.

[0007] Rain gutters are of course also well known and usually consist of an elongated trough-like or concave gutter body, which has a shape symmetrical to a longitudinal plane, so that it has a semicircular or U-shaped profile in cross-section and the gutter opening is located on the upper side when installed.

[0008] Such gutters are usually attached to the eaves of a roof using separate gutter hooks, each gutter hook having a fastening section for attaching the hook to the roof and a hook section complementary to the cross-sectional shape of the respective gutter, into which the gutter is inserted from above.

[0009] When a roof is covered with a sandwich element or sandwich panel, there is a certain challenge in attaching the rain gutter in a stable and aesthetically pleasing way, because the sandwich element has a relatively large height in the thickness direction and the individual components have only a relatively low load-bearing capacity.

[0010] From GB 1 516 139 A, a rain gutter is known which has an elongated gutter body with opposing, parallel side walls and a bottom wall, wherein one of the side walls, when installed on the roof in front of the eaves, is higher than the other side wall, measured from the base of the bottom wall. The rain gutter is attached to the underside of a roof with a trapezoidal cross-section by means of a rivet on the lower side wall. The higher side wall, when installed in front of the eaves, is attached to the roof by means of a fastening clamp or bracket, the fastening clamp / bracket extending at least partially from this higher side wall across the gutter opening.In one version, the mounting bracket is double-layered, so that the flat roof section is inserted between the two layers of the bracket and fixed to the underside of the roof via a rivet that passes through the bracket. In another version, the higher side wall located in front of the eaves of the roof is attached to the upper sides of adjacent corrugations using two mounting brackets.

[0011] Hooks for fastening a conventional symmetrical, trough-shaped gutter with approximately equal sidewall heights are known from DE 20 2018 107 015 U1 and DE 2018 005 953 U1. A fastening section of the hook has a central web that is approximately the width of a high rib of a trapezoidal sandwich panel, and a pair of lateral tabs that are bent from the opposite longitudinal sides of the central web so that they approximately correspond to the course of the high rib when the fastening section is placed on it. The hook is bent downwards immediately at the eaves edge of the sandwich panel and extends from a first (rear) sidewall around the bottom of the trough-shaped gutter to a second (front) sidewall. The gutter thus rests, as it were, on the bracket. In particular, the bracket does not extend over the gutter opening.

[0012] From CH 98 970 A, a suspension device for a gutter is known, comprising a curved metal hook made from a strip of sheet metal into which the gutter is inserted, and which has a bracket at one end facing the building that can be nailed to an eaves board under a roof covering, and which has an end flap at another end that encompasses the outer folded edge of the gutter. A further metal strip grips the end flap at the outer folded edge of the gutter and extends across the opening of the gutter to a rafter under the roof covering, to which it is nailed.

[0013] It is an object of the present invention to provide a sandwich element equipped with a rain gutter that is inexpensive to manufacture, easy to assemble and integrates in an aesthetically pleasing manner into the architectural design of a building covered with a sandwich element.

[0014] The invention proposes a sandwich element equipped with a rain gutter and comprising the features of claim 1. Preferred embodiments are specified in the dependent claims.

[0015] The invention therefore relates in particular to a sandwich element with a rain gutter, wherein the rain gutter comprises an elongated gutter body with a first side wall extending in a longitudinal direction of the gutter body, a second side wall opposite the first side wall at a distance, and a bottom section connecting the first and second side walls, wherein a gutter opening is formed between the first and second side walls through which rainwater can enter the gutter body to be collected, and at least one mounting bracket for attaching the gutter body to a sandwich element. The at least one mounting bracket extends from the first side wall at least partially across the gutter opening in order to attach the gutter body to the sandwich element in such a way that the first side wall is spaced away from an eaves or edge region of the sandwich element such that the eaves or edge region is not obstructed.Water running off the edge of the gutter enters the gutter opening.

[0016] In the case of the rain gutter, the first side wall and the second side wall define a vertical direction of the gutter body, and the first side wall has a greater height in the vertical direction measured from the lowest bottom of the floor section than the second side wall, so that the first side wall, when installed on the sandwich element, at least partially covers the eaves or edge area of ​​the sandwich element.

[0017] In the case of the rain gutter, at least one mounting bracket also has a fastening section for attachment to a top side of the sandwich element, and a connecting section that connects the fastening section to the first side wall of the gutter body in a force-transmitting manner.

[0018] In the case of the rain gutter, the fastening section then has a central web which has approximately the width of the top of a high rib or the bottom of a low rib of the sandwich element, and a lateral tab or a pair of lateral tabs which are arranged at an angle to the central web so that they approximately correspond to the course of the high rib or the low rib of the sandwich element, such that the tab(s) can be placed with the central web on the top of the high rib or the bottom of the low rib, and wherein, in the case where the pair of lateral tabs is provided, they are connected to each other via the central web in such a way that they can overlap the top of the high rib with the central web or be fitted into the bottom of the low rib.

[0019] Furthermore, the mounting bracket is angled relative to the surface of the first side wall in such a way that it extends in the direction of a roof slope of the sandwich element.

[0020] The sandwich element with rain gutter according to the invention offers the advantage that several functions in the area of ​​the eaves end of a sandwich element are realized with a single component, namely that of the rain gutter (catching, collecting and transporting rainwater through the gutter body as such), that of the eaves flashing (preventing water from escaping to the rear on the underside of the sandwich element through the rear or second side wall) and that of the so-called wind deflector (covering the front or end face of the sandwich element through the front or first side wall).Furthermore, reliable attachment of the rain gutter to both the top and bottom of the sandwich element is possible due to the different heights of the first and second side walls of the gutter body in conjunction with the mounting bracket attached to the first or front side wall, which overlaps the gutter opening and is attached to the top of the sandwich element, and the second flange of the second or rear side wall, which is attached to the bottom of the sandwich element.

[0021] Preferably, the central web and / or the tab or tabs extend beyond the channel opening to the first side wall and are attached to the first side wall or are integrally formed with it so that they form the connecting section.

[0022] Preferably, the connecting section has a section connected to the first and second side walls, which extends like a bridge over the channel opening.

[0023] Preferably, the first side wall has a first flange extending in the longitudinal direction of the channel body, which at least partially covers the channel opening in the longitudinal and transverse directions.

[0024] Preferably, the first flange of the channel body is integrally formed as part of the first side wall.

[0025] Preferably, at least one mounting bracket is attached to the first flange or is integrally formed with it.

[0026] Preferably, the mounting bracket is a plate-like extension of the first flange, which extends in the longitudinal direction of the channel body over several corrugations of the sandwich element.

[0027] Preferably, the second side wall has a second flange which is designed so that, in the installed state, it overlaps a bottom surface of the sandwich element, preferably rests against it, and can be attached to it.

[0028] Preferably, the second flange extends from the second side wall to the outside of the channel body.

[0029] Preferably, the second flange is integrally formed as part of the second side wall.

[0030] Preferably, at least one mounting bracket extends from the first side wall beyond the channel opening and the second side wall.

[0031] Preferably, several of the at least one mounting brackets for attaching the channel body to the sandwich element are provided spaced apart in the longitudinal direction of the channel body.

[0032] Preferably the mounting bracket(s) is / are integrally formed with the channel body (10) and / or the channel body is formed as a sheet metal bent part and preferably has a polygonal cross-section.

[0033] Preferably, the mounting bracket(s) have a fastening section for an attachment, in particular a snow guard system, leaf guard and / or bird deterrent.

[0035] The rain gutter 1 for sandwich elements S of all embodiments and examples has an elongated gutter body 10 with a first side wall 11 extending in a longitudinal direction X of the gutter body 10, and with a second side wall 12 opposite the first side wall 11 at a distance. In the installed state on the sandwich element S, the first side wall is further away from the eaves area than the second side wall 12, as shown in the figures, which depict the rain gutter in its installed state.

[0036] A bottom section 13 connects the first side wall 11 and the second side wall 12 in the longitudinal direction X, so that the channel body forms a concave, trough-like shape and the channel opening 14 formed between the first and second side walls 11,12 can be arranged opposite the bottom section on the top side in the installed state, so that rainwater running off from the eaves area can enter the channel body 10 via the channel opening 14, where it can be collected and drained away.

[0037] The rain gutter 1 of a sandwich element according to the invention further comprises one or more mounting brackets 20 for attaching the gutter body 10 to the sandwich element S, wherein the mounting bracket(s) can be formed integrally with the gutter body 10 or can be designed as a separate component adapted to the respective gutter body in terms of shape and dimensions. In the following description, reference is always made to a single mounting bracket, although several such brackets can be provided at intervals in the longitudinal direction X, depending on the longitudinal dimensions of the gutter body.

[0038] According to a first inventive concept, which is realized in the first and second embodiments and in the second to fourth non-inventive examples, the first side wall 11 and the second side wall 12 define a vertical direction Z of the channel body 10, and the first side wall 11 has a greater height H1 in the vertical direction Z (measured from the lowest point of the bottom section 13) than the second side wall 12. The different height dimensions of the first side wall—which is located further outwards in the installed state—and the second side wall, which is closer to the eaves, mean that the first side wall 11, when installed, at least partially, and preferably completely, covers the sandwich element S parallel to the eaves or edge area T of the sandwich element S when viewed from the outside. The required height dimension of the first side wall 11 depends, firstly, on the thickness of the sandwich element S.The height of the sandwich element, the roof pitch, and the installation height above ground, as well as the desired coverage, are all factors to consider. In any case, the greater height of the first side wall relative to the second side wall results in a cross-sectional profile of the gutter body that is asymmetrical perpendicular to the longitudinal direction X. This profile—compared to cross-sectionally symmetrical gutter profiles in the prior art—achieves better visual coverage of the end or eaves area of ​​sandwich elements, especially since the sandwich element typically lies over the gutter body along its entire thickness. A further advantage of the inventive design with a higher first or second side wall is that...The advantage of the outer side wall is that water flowing towards the eaves area on the top of the sandwich element at a certain flow velocity cannot simply shoot out over the channel body but hits the inside of the outer side wall and is then directed into the channel body.

[0039] According to a second inventive concept, which is implemented in the first to fourth non-inventive examples and in the first and second embodiments, the mounting bracket 20 extends from the first side wall 11 at least partially, preferably completely, across the channel opening 14 in a bridge-like manner, so that the channel body 10 can be attached to the sandwich element S in such a way that the first side wall 11 is spaced far enough away from the eaves or edge region T of the sandwich element S that water running off the eaves or edge region T can freely enter or drain into the channel opening 14. The channel body 10 is thus suspended from the mounting bracket, which can therefore be referred to as the top flange bracket, and is not supported from below as in the prior art.In addition to improved mechanical stability of the bracket, the mounting bracket of a sandwich element according to the invention requires less material, since the bracket does not have to wrap around the underside of the gutter body. Furthermore, it easily prevents the gutter body from tipping outwards, away from the eaves area.

[0040] Preferably, the height H 1 of the first side wall 11, measured in the vertical direction Z from the lowest base of the floor section 13, is more than 130%, more preferably more than 150%, more preferably more than 200% of the height H 2 of the second side wall 12.

[0041] The mounting bracket 20 (or the multiple mounting brackets) for attaching the gutter body 10 to the eaves area of ​​the sandwich element 20 is / are preferably formed integrally with the gutter body 10 with its essential components, but can also be formed as a whole or in parts (e.g. in the form of the fastening section and the connecting section described later) as a separate component or as separate components and be detachably (by screws) or at least not without partial destruction, i.e. indetachably (by a rivet connection, a weld connection, a folded connection).

[0042] The mounting bracket comprises a fastening section 21 for attachment to a top surface of the sandwich element S, and a connecting section 22 that forcefully connects the fastening section 21 to the channel body 10, namely the first side wall 11 thereof. The fastening section 21 comprises a central web 23, which has a width approximately equal to the upper end of a high rib HS of the sandwich element S, in order to be placed upon it, and, according to the invention, a lateral tab 24 or a pair of lateral tabs 24, which are arranged at an angle to the central web 23 and bent downwards so that they approximately correspond to the course of the high rib HS of the sandwich element S, such that the tab(s) 24 with the central web 23 can be placed upon the top surface of the high rib HS.In the case where the pair of lateral tabs 24 is provided, these are connected to each other via the central web 23 in such a way that they form a downwardly open V or U profile, in which the central web 23 and the lateral tabs 24 can overlap the top of the high rib and partially its flanks in a bridge- or clamp-like manner (see . Fig. 10 / 11 , 16-18 In this design, the rain gutter is securely fixed to the high rib in the transverse direction of the sandwich element; the fastening to the sandwich element does not require screws that extend through the sandwich element because screws can be inserted in different directions through the tabs and the central web; and the mounting bracket has high dimensional stability.

[0043] In one variant, the central web can also be placed on the base between two adjacent high ribs HS (i.e., on the base of the low rib TS) (see Fig. 4-6 ) and in another variant (not shown), one or a pair of tabs can be curved upwards laterally on the central web to abut the lateral flanks of the high ribs HS adjacent to the low rib, i.e., to be fitted into the cross-section of the low rib TS. In one of the Fig. 5 In a similar variant, but not shown in the figures, the central web (without side tabs) can also be placed on the top of the high rib HS.

[0044] The central web 23 and / or the tab or tabs 24 can extend across the channel opening 14 to the first side wall 11, be attached to the first side wall 11 or be integrally formed with it, and thus form the connecting section 22 (see Fig. 16-18 This variant is particularly advantageous for integral design and possesses good resistance to bending and torsional loads. The mounting bracket 20 can extend from the first side wall 11 across the channel opening 14 and the second side wall 12 (see Fig. 1-3 However, viewed in cross-section, it can also project from the first side wall only over part of the channel opening towards the wide side wall, if, as in Fig. 3 bis 18 shown, the second side wall is set back so far from the eaves end of the sandwich element on the underside of the same that the mounting bracket can be attached to the top of the sandwich element in the eaves area.

[0045] In another variant, not shown, the connecting section 22 can have a section connected to both the first and the second side walls 11, 12, which extends like a bridge over the channel opening 14. In this embodiment, the dimensional stability of the channel body, in particular of the two side walls relative to each other, is improved.

[0046] Preferably, the first side wall 11 has a first flange 15 extending in the longitudinal direction X of the channel body 10, which at least partially covers the channel opening 14 in the longitudinal and transverse directions X,Y and which is preferably integrally formed as part of the first side wall 11 by being bent along the longitudinal direction as an edge strip of the side wall from this to the inside of the channel body (see Fig. 13-18 ). The flange 15 improves the shape stability of the channel body and prevents water from flowing out towards the front.

[0047] The mounting bracket(s) can be attached to the first flange 15 as a separate component, for example by means of screws, rivets and / or adhesive, welding or folding connections (see Fig. 16-18 ) or be wholly or partially integrated with it (see Fig. 13-15 ).

[0048] Preferably, the second side wall 12 also has a second flange 16, which is designed such that, in the installed state, it overlaps an underside of the sandwich element (S) by preferably being integrally formed as part of the second side wall 12, which is bent along the longitudinal direction as an edge strip of the side wall from this to the outside of the channel body 10, and preferably rests against the underside of the sandwich element S, and can be fastened to this by means of suitable fasteners such as adhesives and / or screws 27 or rivets or fastening clips or self-drilling screws (see Fig. 7-18 , in particular Fig. 9 , 15 , 18 The second flange may have predefined holes and / or markings for this purpose.

[0049] In an alternative variant not shown, the second flange can also be bent towards the inside of the channel body, for example if the second side wall is spaced so far away from the first side wall that it is set back sufficiently from the eaves end of the sandwich element so that the second flange, projecting inwards, can still rest against the underside of the sandwich element and be attached to it.

[0050] On the surface of the second flange 16 facing the sandwich element, which is to be attached to the underside of the sandwich element, a sealing material, preferably in the form of a layer of sealing material, for example a sealing rubber strip, can be arranged, preferably glued, over the entire length of the channel body in the longitudinal direction X, in order to prevent water from escaping from the channel body to the rear (for example by capillary action between the flange and the underside of the sandwich element) in the installed state.

[0051] According to a further variant based on a fifth non-inventive example, which is in Fig. 19 As shown, the mounting bracket 20a can be designed as a strip-like bracket or a clamp and can encircle the cross-section of the channel body (10) on the outside. At one end section of the bracket, the fastening section 21 is provided for attachment to the top of the sandwich element S, similar to the example shown. Fig. 2 The mounting bracket 20a is provided with a further fastening section 26 at the other end section for attachment to the underside of the sandwich element S, similar to the second flange of the second side wall described above, and is bent in the corresponding directions. The mounting bracket 20a is attached to the sandwich element as described in the other embodiments and examples. For fixing, the mounting bracket can be used as shown in the Fig. 19 The mounting bracket 20a can also be attached to the channel body via one or more screws or rivets, as indicated. In this variant, the mounting bracket 20a can also consist of two parts that are not directly connected to each other, but are both attached to the channel body. Although not shown, this variant can also include a flange extending in the longitudinal direction X of the channel body 10, which is bent at the top of the first side wall towards the opening of the channel body or towards the second side wall. The second flange provided on the second side wall 12 in other variants can also be included, although it is unnecessary, at least for attaching the channel body to the sandwich element.

[0052] According to a further variant based on a sixth non-inventive example, which is in Fig. 20 As shown, the mounting bracket 20 can form a plate-like extension 15a of the first flange 15, which, when installed, extends along the longitudinal direction X of the channel body 10 on a sandwich element, over several high and low ribs HS, TS of the sandwich element S. The plate-like extension 15a of the first flange 15 can be integrally formed as part of the flange by increasing its width in the transverse direction Y until it overlaps the eaves area of ​​the sandwich element sufficiently on the top side to allow fastening with fasteners (screws, rivets, or the like), or it can be connected to the first flange 15 as a separate plate-like element. In this version as well, the drainage of rainwater into the channel body is ensured by the lower low ribs TS of the sandwich element, while at the same time preventing larger foreign objects (e.g.,Branches, leaves, or snow can get into the gutter body and obstruct the flow of rainwater. This variant is therefore particularly advantageous because it integrates this additional protective function into the component.

[0053] The Fig. 21 Figure 1 shows a further variant according to a seventh non-inventive example in the installed state on a sandwich element. In this variant, which can also be applied to all other embodiments and examples, the first side wall 11 is arranged relative to the mounting bracket 20 such that, in the installed state, it lies approximately parallel to the end face of the sandwich element S. For this purpose, the mounting bracket 20 (here exemplified by the integral strip- or plate-like extension 15a of the first flange 15 on the upper side of the first side wall 11, as in the variant shown in Figure 1) is attached to the upper surface of the first side wall 11. Fig. 20 The first side wall is angled relative to its surface so that it extends in the direction of the roof slope. The height H1 of the first side wall is again measured from the base of the gutter body 10 and is greater than the height H2 of the second side wall 12, which here is formed only by a side strip curved or bent upwards from the base (the lower part of the first side wall 11 also includes such a side strip curved or bent upwards from the base). Here too, the side walls can be bent upwards at essentially right angles from a flat section of the base to form a gutter body approximately U-shaped in cross-section.The fastening on the underside of the sandwich element is carried out via a second flange 16 on the top of the second side wall 12 and the fastening on the top of the sandwich element is carried out via the plate-like extension 15a of the first flange 15, which serves as a mounting bracket 20.

[0054] In sandwich elements S according to the invention, the rain gutter 1, i.e., the gutter body and the mounting bracket, is designed as a sheet metal bent part(s), particularly when configured as an integral component but also when these components are configured as separate parts. From a manufacturing perspective, it is advantageous to design the respective profiles with a polygonal cross-section, whereby partial areas, for example the lower part of the gutter body, can also be curved or arc-shaped (see Fig. 10-15 , 20 und 21 ).

[0055] In other variants not shown, the mounting bracket 20 can have an integrally molded or attached mounting section 25 for a further external attachment, in particular a snow guard system, leaf guard and / or bird deterrent. With this design, several functions are combined in the rain gutter and the installation time is correspondingly reduced.

[0056] The various versions of the channel body and the mounting bracket can be combined in variants that are not shown as embodiments or examples, within the limits specified in the claims.

[0057] The invention relates to a sandwich element according to claim 1, in particular a sandwich element to which a rain gutter is attached in such a way that the first side wall of the rain gutter at least partially, preferably completely, covers the eaves or edge area of ​​the sandwich element.
