Abstract

The longitudinally adjustable interlocking roof tile has a rectangular shape in plan view. Its upper side is substantially uniformly profiled. It possesses a head, a covering, foot and side overlap and in each case a corner cutout in the foot side-lap corner and in the head covering-lap corner. A head-edge rib passes round the head covering-lap corner, forming an angle. The foot-lap part consists of two foot-lap ribs. When laying the interlocking roof tile, a vertical lateral expansion joint is produced. The head-lap part is equipped with a continuous inner head-lap rib which, together with an inner foot-lap rib, is not as high as the outer foot-lap rib. <IMAGE>

Description

The present invention relates to a top view of a rectangular grooved tile having a substantially unchanged profile on its upper face, a grooved-ribbed head, top, foot and side salt portions and one corner cut at the heel and the top of the head. a rib is guided and the foot section consists of two foot ribs and a longitudinal side groove.

A longitudinally movable tile is described in

German Patent No. 44,227. There is only one and only a very small headband mentioned here. This has the advantage of having a low stacking height for storage, but has the disadvantage of placing rainwater or snow under the pots after laying pots. The supporting ribs are located on the other side of the tile under the two recesses, which is very unfavorable from a static point of view. The tile can easily break in the transverse direction.

Sliding tiles can only be used on steeper roofs than conventional tiles, due to the professional rules for roofing, so the longitudinal sliding grooved tiles have a limited application.

SUMMARY OF THE INVENTION The object of the present invention is to provide a longitudinally slidable tongue-and-groove tile having a relatively slight overlap in its head when loaded and, despite this slight overlap, at a less steep roof pitch

-3 provides insured roofing.

The present invention solves this problem by providing the headband portion with a protruding inner headboard, the height of which, together with the height of an inner leg rib, is lower than the height of the outer footboard.

The grooved-tile tiles of the present invention simultaneously satisfy several conflicting conditions. It has a relatively large surface area which results in a small number of pieces per square meter. On the other hand, despite the relatively large bridged surface per tile, it provides adequate load protection.

Because the tile is slidable in the longitudinal direction, it provides flexibility when loaded so that it can be loaded not only in a predetermined arrangement but also has a relatively large offset play. It is equally secure against wind-blown precipitation when pulled down or retracted, since the inner headboard, together with the footboard, forms a labyrinth seal in each condition. Not only is the fluted tile protected against infiltration, but condensation on the inside of the overlapping tile is drained to the outside of the overlapped tile underneath. For this purpose, the headboard has the usual overflow heads.

Due to its better sealing properties, the fluted tile of the present invention can be used for roofs with a smaller pitch.

It is advantageous to use a tile for the sealing to be achieved

-4 having an elevated center portion and center field recesses arranged to the right and left thereof, wherein the inner headband at the upper surface of the cover portion at the raised central portion and the inner lateral rim at the same height as the axillary rib. This ensures that the overlapping tiles are slidable.

A further advantage of the present invention is that the tile is provided with support ribs on the back of the tile which pass through their slanting ends and extend to the inner leg edge. As the tile to be overlapped is shifted, these support ribs slide on the headboard rib, because the height of the outer footboard and the headboard ribs are so designed that the support ribs could be extended to the inner footboard. This not only increased the load-bearing capacity of the tiles, but also improved the drainage of condensation water, as any condensation formed on the top of the interlaced tile was drained. The extended support ribs ensure that the condensation water flows to the overlapped tile at the inner footboard.

A similar advantage derives from the fact that at the other side of the lateral flange there are also support ribs which pass at their foot end into a free flat sheet, the width of which corresponds to the lateral flange and its length is determined by the thickness of the offset . In this case too, the support ribs improve the tile

-5 pressures and drainage of any condensation formed.

It is advantageous to have both protrusions at each head and foot of the tile. Even with curved tiles, they provide a secure rest when placed.

The drainage of condensation water can also be facilitated by providing one or more Y-shaped support ribs between the support ribs in the center field of the back of the tile. They direct condensate from the higher center to the support ribs, from where the condensate is drained. The Y-shaped support ribs enhance the stability of the tile and serve as a water deflector.

The invention will now be described in more detail with reference to the drawings in connection with an exemplary embodiment. The attached drawings show

The grooved-ribbed pot 1 according to the invention has a length L

It has a longitudinally displaceable section and has a rectangular top view. It has a groove-ribbed head 2, a groove-ribbed cover 3, a grooved-ribbed foot 4 and a side flange 5. The tile shown has a central part 6, the profile of which is substantially unchanged and extends from the head 2 to the foot 4. The recesses 614 and 616 are located on either side of the raised field 612 of the central portion 6.

The groove-ribbed head is formed by a headboard rib 211 extending from the side flange 5 to the cut-out corner cut-out 296 across the entire width of the tile so that the cut-out 296 is perpendicular to the outer face of the cover flap 311. The headboard rib 211 is located in front of an inner headboard rib 217 extending from an internal lateral edge rib 517, also mentioned, to the outer face of the topsheet 311, extending across the entire center field. The head flange 217 has the same cross-section along its entire length, and has recesses 217.1 in the recesses 614 and 616, which provide the flow of water that may have accumulated in the middle head recess 216. This applies primarily to condensation water, which may drip from the cover change.

At the left end of the axle fin 211 is a lower one

There are 211.2 planes. The cover portion 3 comprises a higher center portion 312 having a height equal to the raised area 612. An inner cover flange side panel 313 provides a connection between the protrusion 312 and the recess 616.

-ΊΑ. The outer face 311 of the topsheet 3 forms one of the longitudinal sides of the tile.

Starting from the head 2, an outer lateral flange 513, a central lateral flange 515, and an inner lateral flange 517 extend side by side to the end of the foot portion of the tile, and to the foot portion 48 formed therein. The lateral edges have a constant cross-section along their entire length. An outer side groove 514 is formed between the outer lateral flange 513 and the central lateral flange 515. A corresponding inner side groove 516 is formed between the central lateral flange 515 and the inner flange 517. The foot end of each side groove extends into a side flange 487 which deflects water sideways. An elevated plane 481 defines a bottom deflector groove 487 from the bottom to the left.

As shown in Fig. 2, a headband strip 222 extends from the side panel of the inner topsheet 313 to the outer rib of support pair 623 disposed beneath the side flange 5. Said outer support rib 623 serves for lateral delimitation of the tile and is further elucidated. Below the central recesses 614 and 616 are provided two hook rails 221 which are slightly offset from the headband 222 towards the inside of the tile at the head of the tile.

Underneath the recess 616, a pair of left support ribs 621 extends from the hook 221 to the foot portion. The ribs

Starting at the foot of the hooks, they begin with a slight upward section 621.1 and then reach the full height of the rib, running unchanged towards the foot, and the bevels of a 626.3 pass into a deeper section 626.2. The slope 626.3 and the deeper section 626.2 are shown in Figures 4 and 5. These sections of the support ribs lead to the inner 427 foot skirt, which will be described below, while also providing sliding of the tiles.

A similar support rib 625 is disposed below the recess 614 in the center field. This, as shown in Figure 2, is led from the right hook 221 to the right foot 427.1.

Below the raised center field portion 612 are two Y-shaped support ribs 628.1. One of these, parallel to the longitudinal edge of the tile, begins at the headband 222 and has a constant cross-section leading to the initial portion of the support ribs 621, where the support rib splits and extends outwardly to the support ribs 621 and 625, respectively.

The support rib 628.1 is similar in shape to the foot, but is rotated 180 ° relative to the head. Both Y-shaped support ribs serve to collect any condensation water that may be formed on the backside of the raised center field 612, which is led to the support ribs 621 and 625 and thus directed to the foot portion.

For this purpose, the toe support 628.1 extends to the inner toe rib 427 and outer toe 423

-9vezetve.

Between headband 222 and hook nose 221, headband grooves 222.1 are arranged in the recesses of center field 614 and 616. Below the lateral flange portion 5, there is a headboard 222.3 on the head portion, which is delimited by a recess 623.2 formed as a continuation of the support rib 623 towards the outside of the adjacent tile.

Said support rib 623 is one from the head of the tile

623.1 is guided to the footplate, which defines the tilt range of the tile. Like the ribs 621, this rib has an ascending section of the head section 621.1, as shown in Figures 4 and 5.

From the head cut-out 296, the outer cover rib 323 and the inner cover rib 327, which extend to the foot flank 423, start.

At the head and feet, these ribs have protrusions 323.3 and 327.3 so that the tiles are properly supported by the roofs even when bent. The ribs 323 and 327 surround a cover groove 324 and have a constant cross-section along the entire length of the tile.

An inner cover groove 328 is formed between the inner cover rib 327 and the support rib 621.

The outermost closure of the foot portion is formed by the foot flange 423, which runs from the left edge of the tile to the foot cutout 486 in FIG. Arranged inward from this rib are two independent leg ribs 427.1,

-10 which are connected by the connecting ribs 431 to the foot flange 423.

The support ribs 621, 623, 625 and 628 serve not only to increase the load-bearing safety of the tile, but also to direct the drainage of condensate that may form on the inside of the tile. In Figure 3, it can be seen that the support ribs 621 and 625 disposed beneath the center recesses 614 and 616, together with the side walls of the recesses, form a trapezoidal, high-load cross-section.

The special features of the grooved tile are described below.

The headboard rib 211 is flattened at the height of the outer side edge rib 513 around the headboard flange 28. The resulting plane 211.2 has a width equal to the width of the head-to-edge cutout 296, including the mid-side play.

The width of the center field 6 is dimensioned such that a

Cover the top portion 312, including the inner side flange 517 and the mid-side play.

This is necessary to ensure a good connection when laying the tiles.

Instead of the raised middle part 6, a flat or curved middle part can also be formed, in which case the ribs 423 and 427 are modified accordingly.

The height of the inner side flange 517 is the same as the middle portion and the middle portion 312 of the top portion. On the one hand, for the sake of maximum seepage protection,

On the other hand, in order to obtain as small an overlapping area as possible, the cross-section of the outer side-flange 513 is formed higher and wider than the cross-section of the middle-flange 515.

For longitudinal stability and because the roof tiles are generally delivered with their side flange portion 5, it is advantageous to provide the outer side flange 513 with sufficient strength.

As a further safeguard against transport damage, a further edge flange 513.6 is provided at the edge of the tile before the outer side flange 513. The height of the raised plane 481 is at least equal to the height of the outer side flange 513. This prevents rainwater from flowing over the plateau 481, especially with steeply rising roof structures. The water deflector 487 is designed to guide rainwater flowing through the side grooves into a tile overlaid on the bottom left. The two lateral grooves 514 and 516 have the same depth.

The center field 6 is as high as the center field 312 of the cover portion. The center fields 6 are bounded by left and right sides 613 and 615 respectively.

The side panels 613 and 615, as well as the side panels 313 of the inner top flange and the inner side panel of the inner side flange 517, form an angle of 30 ° with the plane perpendicular to the tile plane.

This angle is determined by static considerations to ensure the tile strength and stiffness

-In the case of desiccation wet and dry, and in the oven and on the roof is enhanced. In the middle part 6, recesses 614 and 616 are connected to the side panels 613 and 615. At the foot of the recesses 614 and 616, the loading supports 614.1 and 616.1 are arranged.

If, as in another embodiment, the raised area of the middle portion is not formed between the inner lateral flange 517 and the grooved flanged top portion, a through-hanging nose may be provided instead of the two hooks 221. On the backside, the headband 222 and the groove 222.1 in this case may extend over the full width of the tile. A left pair of support ribs 621 shown in Figure 2 is required to prevent fracture. The ribs of the pair of ribs 621 are of the same height in the middle section.

The support rib 625 is substantially the same height as the support pair 621. Ribs 626.3 of the ribs 621 and 625 and a

The recesses 626.2 are dimensioned in their height so as to leave a gap between the headboard rib 221 of the tile to be overlapped and said elements.

Condensation or leakage water from support ribs 621 and 625 extends into recesses 626.2 and drips into the space of the lateral foot ribs 427.1, where the lateral foot ribs 427.1 overlap with the lower tile roof. The angle of the slope 626.3 from the upper plane of the support ribs 621 and 625 to the foot plane of the recesses 626.2 shall be less than the minimum angle of incline of the rafters minus the tilt of the tiles.

In the support ribs -13Α 623, the recess 626.2 following the support ribs 621 and 625 is not formed. This is not necessary in the lateral periphery because no overlapping condensation or leakage occurs.

The outer support rib 623 rests only with the recess 623.2 on the roof lath to provide a narrow and defined tile face. The outer support rib 623

The recess 623.2 does not obstruct the horizontal loading because in this position it lies on the plane 211.2 of the curb 211.

The right abutment rib 623 ends at the foot portion at the foot portion 623.1. It is as wide as the lateral side portion 5 on the other side. The length of the plane 623.1 is determined by the desired degree of longitudinal displacement of the tile, including the thickness of the headboard rib 211, since when displaced the head of the covered tile moves below the plane 623.1 until the start of the support pair 623.

The height of the Y-shaped support rib 628.1 is substantially the same as the height of the headband 222. The purpose of the Y-shaped support rib 628.1 is to drain the condensation or leakage water to the arrow-shaped ends on the back of the tile, while increasing the stability of the center field 6. The drainage is then led along the support ribs 621 and 625 toward the foot portion of the tile through the slopes 626.3 to the recesses 626.2, and then water drips in the space of the foot ribs 427.1. The ribs 427.1 overlap with the tile roof below them, ensuring further drainage.

The support ribs 621 and 625 and the left support rib 623 are disposed directly below the side panels 313 and 615 of the inner cover flange 313 and the center panel 6. This arrangement serves to strengthen the cross-section of the tile and to increase its longitudinal stability, thereby increasing the load capacity of the tile.

The cover flange edge strip 323.2 is formed toward the edge of the tile 323 in front of the outer cover rib and serves to protect the outer cover rib 323 from damage.

The outer cover rib 323 is wider and higher than the inner cover rib 327. The reasons for this are the same as for the lateral flanks 513 and 515. Projections 323.3 and 327.3 are formed in the head and foot compartments of each of the cover ribs 323 and 327. The purpose of these is to ensure that the two ribs 323 and 327 are positioned freely between the protrusions 323.3 and 327.3 without lying down. This way, even when the tile is bent, it will be able to rest properly.

At the foot end of the protrusions 323.3 and 327.3, the cover ribs 323 and 327 are extended to the foot edge 423. The height of these extensions corresponds to

323.3 and 327.3, except for the height of the plane plate 481 above which the said extensions are placed when the tiles are placed.

The foot flange 423 is formed with a recess 423.1 in accordance with the center field 6. This is where the 6 middle fields of the lower tile and the blanket overlap • · »· · ·«

-15 parts and 517 inner side cover ribs. If the center field 6 is not formed in a protruding form, it may have the same height up to the end of the foot flange 423.

The foot rib has two 427.1 lateral sections. These sections 427.1 are in line with the inner foot rib 427. When overlapping, the two sections 427.1 lie in recesses 614 and 616.

The height of the inner foot rib 427 is dimensioned such that, as the tile is displaced, the rib 427 can slip over the head rib 217 as shown in Figures 4 and 5.

Between the inner toe rib 427 and the lateral portions 427.1 thereof are known connecting ribs 431. These are used to increase the stability of the foot section of the tile.

The Y-shaped support rib 628.1 disposed in the space of the foot portion of the tile performs substantially the same function as the Y-shaped support rib 628.1 formed at the head. Due to the drainage of condensation and runoff water on the backside, the stem of Y is obviously pointing in the opposite direction.

Figure 3 is a cross-sectional view of two overlapping tiles. The cover ribs 323 and 327 of the cover portion 3 extend into the outer and inner side grooves 514 and 516, respectively. The headgear

The projections 323.3 and 327.3 lie on the bottom plane of the side grooves 514 and 516, while the ribs 323 and 327 are located above the bottom plane.

The outer side flange 513 is wider and taller,

like the 515 center flank.

The inner side flange 517 is formed as high as the raised middle part 312 of the top part 3 and the upper part of the middle field 6.

Between the left and right tiles, a vertical rain channel 961 is formed. The pair of support ribs 621 of the left tile is arranged as an extension of the side panel of the inner cover flange 313 and the side panel of the center panel 615. The support rib 625 is disposed below the left side panel 613 of the center panel 6.

Each of the center field side panels 613 and 615, the inner top flange side panel 313, and the inner side flank inner panel 517, have an angle of approximately 30 ° to the plane perpendicular to the tile plane, which is static, namely to provide load (step strength).

The head flange 217 begins at the inner side flange 517 and runs at the same height and width to the outer face 311 of the top portion 3.

Figure 4 illustrates the overlapping of two tiles according to the invention. The drawing illustrates the tiles in an unfolded state, taking advantage of the complete unfolding of the tiles! game.

The foot flange 423 rests on the head flange 217, but the inside foot flange 427 does not contact the flap 211.

The distance between the two leg flanges 423 and 427 is less than the flap 211 and the flange 217

-17 distance. The condensation water, which flows along the support rib 625 through the slope 626.3 and the recess 626.2 to the lateral sections of the foot rib 427.1, drips into the central head recess 216 and then through the flow head 217.1 into the center of the tile.

Figure 5 illustrates the upper tile in the extended position, with the support rib 625 not yet leaning against the headboard rib 211. The deeper section 626.2 of the support rib 625 does not contact the head restraint 217 and may move freely above it. At the deeper section 626.2, through the slope 623.2, the support rib 625 is elevated to increase the strength and load capacity of the tile. The inner leg rib 427 is lower than the leg rib 423 because the head rib 217 extends above the center head recess 216 and the center depression 616. The tiles slide with their outer leg fins 423 and the protruding portion thereof in recesses 614 and 616 of the center field. The backside headband 222 is disposed in front of the hooks 221 in the direction of the edge of the tile head. Between headband 222 and hooks 221, headband 222.1 is formed. The support rib 625 is formed with a slope in the direction of the hook 221. The head section 623.2 of the outer member of the pair of support ribs 623 runs all the way to the edge of the tile.

Figure 6 is a cross-sectional view of two stacked tiles of the invention. The upper edge of the tile has a 423 foot flange lying on the tile below. The top tile with its headboard 222.3 as a support surface.1

At -18 rests on the 211 ridge of the lower tile.

If the hanger nose 221 were to be properly extended, it would be possible to stack the pots on the head section with the hanging nails on top of each other. However, hook heights of this height are not strong enough and can easily break.
