Description

Description

[0001] The invention relates to a laying system for roof panels, which comprises a plurality of system rails and suspension brackets to be arranged horizontally and parallel to one another on a roof, wherein each roof panel has corresponding suspension slots for hanging the roof panel in the suspension brackets on opposite sides, which are spaced apart from one another by the width of the roof panel.

[0002] Known laying systems for roof panels such as rhombus, rhombus template, single covering, etc. have so far been carried out by well-trained specialists using hammers, nails and drills.

[0003] However, since in recent years fewer and fewer such skilled personnel have reached professional maturity, the demand for roofing work to be carried out can no longer be adequately satisfied, which is why efforts are being made to simplify the activities to be carried out so that roofing can also be carried out by untrained personnel.

[0004] US 1 738 006 A shows a laying system for roof tiles that are provided with slots on opposite side edges. The roof tiles are attached to the roof with a large number of appropriately shaped Z-shaped hooks, each of which can be hooked onto the roof battens at one end and into the slots in the roof tiles at the other end. Since the loose hooks are only hooked onto the roof battens, there is a risk of the roof tiles becoming loose. A fixed connection of the hooks is not shown in this document.

[0005] A similar installation system to that in US 1 738 006 A is specified in US 5 577 360, whereby the hooks are clamped onto the roof tiles with a spring effect in order to fix them better. Here too, the roof tile bond can become loose over time.

[0006] GB 190927572 A discloses overlapping roof tiles with openings which rest on system rails and are held in place by clamps with bendable legs which pass through openings in the roof tiles. The clamps are slidably clamped onto the system rails so that there is no fixed connection to them and there is therefore a risk of the roof tiles becoming loose.

[0007] The object of the invention is therefore to provide a laying system for roof panels in order to simplify the laying so that it can be carried out precisely and in a time-saving manner even by less well-trained specialists.

[0008] According to the invention, this is achieved in that each system rail comprises a plurality of suspension tabs in the longitudinal direction which are evenly spaced from one another with a fixed system distance, wherein each suspension tab comprises a suspension area protruding from the system rail for suspending two horizontally adjacent roof panels of a roof panel row, and wherein the roof panel width is substantially equal to the system distance.

[0009] The system rails are arranged horizontally and parallel to one another on the roof, which is done via a support structure provided on the roof, whereby after each system rail has been arranged, the roof panels are laid in a row by hanging them in the hanging brackets. Each of the hanging brackets provided on the system rails supports a hanging section of two adjacent roof panels, defined by the hanging slots. The hanging slots of the roof panels and the hanging brackets of the system rails are designed in such a way that adjacent roof panels are arranged with a defined joint spacing between them when hung, which is why the roof panel width is essentially equal to the system spacing. In the event that the gap width s is chosen to be the same for all roof panels, the following applies in this context: % joint spacing s plus 1 roof panel width b plus % joint spacing s = 1 system spacing a (HK s+b+% s = 3).

[0010] The system rails enable the hanging of roof panels arranged next to each other, at the same time they also serve to fix the roof panels arranged below in the direction of the eaves.

ten roof panel row. For this purpose, according to a further embodiment of the invention, the system rails are arranged in an overlapping manner in the area of the ridge side of each roof panel row in order to fix the respective roof panels to the ridge side. When laying, the roof panels are thus hung in one of the system rails and fixed in the ridge area by installing the parallel system rail following in the ridge direction.

[0011] The laying system according to the invention is not limited to any particular laying pattern, but rather all known laying patterns and, in addition, other ones can be implemented with it.

[0012] According to a further embodiment of the invention, it has been found to be advantageous that the suspension tabs of adjacent system rails are arranged offset from one another in the longitudinal direction by half a system distance.

[0013] In this way, the usual offset of the laying joint between the roof panels of adjacent roof panel rows is achieved, at the same time the suspension tabs of each roof panel row are arranged in the central axis of the roof panel row following in the ridge direction, whereby the suspension tabs can be used as additional fixing points.

[0014] According to a further embodiment of the invention, the system rail can be formed by a bent part which has a plate-shaped central part.

[0015] The bent part is easy to manufacture and, due to the plate-shaped middle part, offers sufficient stability and easy installation on the roof.

[0016] In particular, the system rails can be fixed to roof battens of a roof construction, whereby known fastening methods such as screws, nails, etc. can be used.

[0017] According to a further embodiment of the invention, the hanging area of the hanging tabs can be formed by a hanging strip that protrudes at a right angle from the system rail and has a retaining element at its free end. In this way, the roof panels can be placed on the respective hanging strip parallel to the plate-shaped middle part of the system rail, with the retaining element securing the roof panels against sliding out of the hanging strips.

[0018] According to a further embodiment, the retaining element can be formed by a retaining section running parallel to the system rail, which extends from the suspension strip in the ridge side direction.

[0019] In addition to the hanging function, the hanging bracket, as already indicated, also offers a fixing function for the row of roof panels that follows in the direction of the ridge during the laying process, the roof panels of which can be fixed in the area of the lower edge on the eaves side to one of the hanging brackets, e.g. by screwing.

[0020] For this purpose, in a further embodiment of the invention, the suspension tab can each comprise a fixing section which extends from the suspension strip in the eaves side direction and is designed to fix a roof panel of a covering row of roof panels.

[0021] The design of the hanging area of the system rails determines the joint spacing of the roof panels of each row of roof panels, so that the roof panels only have to be hooked in during installation to ensure this joint spacing.

[0022] According to a further embodiment of the invention, it can therefore be provided that the hanging area of the hanging tab has a length which is essentially equal to twice the length of the hanging slots, so that the roof panels of each row of roof panels can be hung next to one another in the hanging tabs when the system rail is mounted on the roof.

[0023] In a variant of the laying system according to the invention, the roof panels can be rectangular or square, with two sides of the roof panels being parallel

are oriented parallel to the system rails, thus achieving the well-known double coverage.

[0024] The fastening of the system rails to the roof is not subject to any restrictions, it can be carried out in particular on known roof battens, whereby according to a further embodiment of the invention each system rail can be bent at an angle on its ridge side for fastening to a roof batten in order to increase the tightening pressure when screwing the system rail tight using an angled screw. The screw penetrating the surface at an angle when screwing in also prevents or reduces splintering of material, e.g. wood.

[0025] In order to prevent the penetration of moisture or particles, according to a further embodiment of the invention it can be provided that a sealing tape is arranged on the system rails at least in some areas.

[0026] Another variant of the laying system according to the invention can consist in that the roof panels are square, with a diagonal of the roof panels being oriented parallel to the system rails and opposite corner regions along this diagonal being cut off parallel to the other diagonal, with the cut-off corner regions forming the opposite sides, which are spaced apart from one another by the extent of the roof panel width (b), and which receive the hanging slots.

[0027] This laying pattern corresponds to the known square template laying, whereby the joint spacing between adjacent roof panels is kept constant by providing the hanging slots for hanging in the hanging tabs of the system rails.

[0028] According to a further embodiment of the invention, the system rail can comprise beads extending at least in the longitudinal direction in some regions for resting on the row of roof panels to be overlapped, thereby preventing the roof panels from resting hollowly and the resulting risk of breakage under load, e.g. when walking on the covered roof.

[0029] Furthermore, the invention relates to the use of a laying system according to the invention for laying roof panels, in particular fiber cement roof panels.

[0043] Fig.1 shows a part of a roof 50 with a laying system for roof panels 1, 2, 3 arranged thereon, which according to the invention comprises several system rails 5 arranged horizontally and parallel to one another on a roof, which simplifies the laying of the roof panels 1, 2, 3. For better understanding, the roof 50 is not shown completely covered.

[0044] The installation method shown in Fig. 1 corresponds to the known double covering, wherein the roof panels 1, 2, 3 are rectangular in shape and two sides of the roof panels 1, 2, 3 are oriented parallel to the system rails 5.

[0045] The roof panels 1, 2, 3 are formed from fibre cement, but roof panels made from other materials can also be used within the scope of the invention.

[0046] The roof panels 1 arranged horizontally next to one another in the area of the roof 50 near the ridge form a row of roof panels and cover the row of roof panels 2 arranged underneath, which in turn cover the row of roof panels 3 arranged in the area near the eaves.

[0047] Each roof panel row is assigned one of the system rails 5, which has a plurality of suspension tabs 6 that are evenly spaced apart from one another in the longitudinal direction with a system distance a (Fig. 4).

[0048] The system rail 5 is - without being limited to this - a sheet metal bent and stamped part which, as shown in Fig. 2, comprises a flat plate-shaped central part 20, a ridge-side angle section 22 and, at the spaced-apart positions at which hanging tabs 6 are formed, a hanging area 7 on the eaves side protruding from the system rail 5 for hanging two roof panels of a row of roof panels which are adjacent in a horizontal direction.

[0049] In addition, the system rail 5 is bevelled at its ridge side in a section 21 (Fig. 2) for attachment to a roof batten.

[0050] The hanging area 7 of the hanging tabs 6 is each formed by a hanging strip 9 protruding at a right angle from the system rail 5, which has a retaining element 10 at its free end, which is formed by a retaining section 11 running parallel to the system rail 5 and extending from the hanging strip 9 in the ridge side direction.

[0051] The roof panels 1, 2, 3 of the laying system according to the invention are designed to be suspended in the suspension tabs 6 of the system rails 5, which is achieved in that each of the roof panels 1, 2, 3 has, at approximately half the height on opposite sides, which are spaced apart from each other by the width b of the roof panel (Fig. 5), corresponding suspension slots 8 for suspending the roof panels 1, 2, 3 in the suspension tabs 6, wherein the roof panel width b is substantially equal to the system distance a.

[0052] The hanging area 7 has a length c (Fig. 6) which is essentially equal to twice the length d of one of the hanging slots 8 (Fig. 8). As a result, two roof panels which are adjacent in a row of roof panels and which protrude into the hanging area 7 with their hanging slots 8 from opposite sides can be hung on each hanging tab 6. The joint distance between the two adjacent roof panels is defined by suitable dimensioning of the length c of the hanging area 7.

[0053] In order to be able to hang the roof panels 1, 2, 3 in the hanging tabs 6 during the laying process, the width e of the slot is selected to be slightly larger than the height of the retaining section 11. The step of hanging the roof panel with the slot 8 in the hanging tab 6 is shown in Fig.9 and 10.

[0054] As soon as the roof panels of a roof panel row are suspended in one of the system rails 5, the next system rail 5 in the direction of the ridge is mounted in an overlapping manner in the area of the ridge side of this roof panel row in order to fix the roof panels 3 to the ridge side.

[0055] The suspension tabs 6 of adjacent system rails 5 are arranged offset from one another in the longitudinal direction by half a system distance a, so that the higher roof panel row following in the ridge side direction is arranged offset by half the system distance a or half the roof panel width b, resulting in the known double-covering structure.

[0056] In addition to the hanging function for the roof panels of a roof panel row, the hanging tabs 6 also have a fixing function for the roof panels of the roof panel row following in the direction of the ridge side, which can be connected to the hanging tab 6 below in its area near the eaves side.

[0057] For this purpose, the suspension tab 6 has a fixing section 12 (Fig. 2) which extends from the suspension strip 9 in the eaves side direction and is designed to fix a roof panel of the covering row of roof panels.

[0058] With reference to Fig.1, starting with the system rail 5 assigned to the roof panel row of roof panels 3, all roof panels 3 are first hung with their hanging slots 8 in the hanging tabs 6 and then, in the area of the ridge side of this roof panel row, as shown in Fig.3, the system rail 5 following in the ridge direction is mounted by a screw 38 which is screwed into the bent section, so that it partially overlaps the roof panel 3 in its ridge-side area and thereby provides hanging tabs 6 for the following roof panel group, into which the roof panels 2 of this roof panel group can be hung. The further group of roof panels 1 is suspended in the same way in the next higher system rail 5 (not shown in Fig. 3), whereby the eaves-side area of the roof panel 1 comes to lie above the fixing section 12 of the suspension bracket 6 and is fixed there, namely screwed tight with a screw 39. The process of fixing could also be carried out differently, e.g. by nailing.

[0059] In addition, a sealing strip (not shown) is arranged on the system rails 5 at least in some areas in order to seal the gap between roof panels 1, 2, 3 and the system rail, thus preventing the penetration of moisture, wetness or particles.

[0060] A further variant of the laying system according to the invention, which corresponds to the known square template covering, is shown in Figs. 11, 12 and 13, in which the roof panels 1', 2', 3° are square, wherein a diagonal of the roof panels 1", 2', 3° is oriented parallel to the system rails 5' and opposite corner regions along this diagonal are cut off parallel to the other diagonal, wherein the sides formed by the cut off corner regions are spaced from one another to the extent of the roof panel width b and the hanging slots 8 are formed.

[0061] During installation, the roof panels 1’, 2”, 3° are hung with their hanging slots 8 into the hanging tabs 6, whereby the sides of adjacent roof panels formed from the cut-off corner areas are opposite each other and separated from each other by a joint spacing.

[0062] The system rail 5 used in Fig.11 comprises beads 13 which extend in the longitudinal direction in some areas and are shown in Fig.13 in an enlarged manner and are designed to rest on the row of roof panels to be overlapped by the system rail 5' in order to prevent the roof panels from lying hollow and thus prevent the risk of breakage.

[0063] Fig.12 shows the overlapping installation of the 5° system rail for fixing the ridge area of the 2” roof panels.
