SI20217A - Drainage grating, especially for exterior construction works - Google Patents

Abstract

The object of invention is a drainage grating for exterior construction works preferentially, especially for covering the upwards opened drainage installations, such as gutters, which comprises longitudinal lath-like elements and transverse elements which are binding the latter preferentially to an undismountable assembly. The grating is preferentially intended for the prevention of icicle growth. According to the invention, the longitudinal laths (1, 3) are shaped and distributed in such a manner that they, in their ground-plan projection, cover the occupied projection plane completely by the drainage grating, leaving a passage for meteoric water among the laths. The complete coverage of the ground-plan projection is achieved by a set of lathe-like elements (1, 3), each of them forming an unsymmetrical miniature roof in principle, where a shorter leg of the miniature roof of a given lath-like element is standing on a longer leg of the miniature roof of the previous lath-like element. The passage for meteoric water is established in the area of the shorter of the two legs of the unsymmetrical miniature roof. On the side far from the roof eaves, the set of lath-like elements (1, 3) is prolonged into an upright snow fence (7).

Drainage grate, especially for exterior construction

The object of the invention is a drainage grating, especially for exterior constructions, in particular for covering upwardly open drainage lines, in particular grooves, comprising longitudinal molding elements and transverse elements which first bind to a preferably non-removable assembly.

Objects of this type are found in class E 04 D 13/06 Int.Cl.

The known lattices defined above are generally hiking lattices.

The invention relates to the problem of the formation of ice candles hanging from the gutters and seeks to prevent the formation of ice candles.

The physics of generating ice candles hanging from gutters is basically as follows:

It starts with snowflakes. The falling snowflakes stop on their way to the ground at the first obstacle they come across, so that the snow also accumulates on or in the roof groove.

The melting of snow in the gutter or on the roof generally begins on the side of the gutter, i.e. metal, or on the side of the roof. The accumulating water from the snow-filled gutter is largely unable to drain, and therefore the water is not dissolved. After freezing, it forms the basis of future ice candles. Namely, the water from the next extraction cannot ice or flush into the gutter and, instead of flowing as expected, it flows over the edge of the gutter and freezes there at sufficiently low temperatures.

Snow also contributes to the filling of the gutters and thus the formation of candles, which, despite the snowfall, slides down from the roof into the gutter.

From the above physics of candle formation, it simply follows that the prerequisite for preventing the formation of ice candles is an empty recess so that the drip can flow freely.

The above conception of the invention is based on the assignment, a well-known lattice defined above, which according to the invention will not be marchable, so modified as to prevent the snow from entering the groove and the formation of snow slush there.

According to the invention, the longitudinal slats are formed and arranged in such a way that the projection plane is completely covered by the drainage grid in the floor plan, and a passage for meteor water is established between them.

This complete coverage of the floor plan projection is achieved by a series of molded elements, each of which essentially forms an asymmetrical ministry, and a shorter limb of the minister of a certain molded element stands on a longer limb of the ministry of the previous molded element.

The passage for meteor water is established within the area of the asymmetrical ministry shorter than two arms.

The series of moldings continues for the last time into an upright border fence.

The invention is hereinafter further explained in the embodiment of the object of the invention, which is greatly simplified, in principle only, by the attached drawings, without any limitation in the scope of patent protection. In the drawings, FIG. Fig. 1 is a final section of a subject drainage grid with a partial cutout in the front wall of the joint enclosure, all in spatial projection with a view at a height above the imaginary groove and looking in the direction of the imaginary roof, FIG. 2 is a detail of a longitudinal strip of FIG. 1 in the same projection as the sketch of FIG. 1, FIG. 3 is an assembly of FIG. 1, here by looking downwards from the imaginary roof and by drawing a termination of the articulated fence, and by not showing the elements for connecting the said grate to the gutter, and FIG. 4 is a detail of a longitudinal strip of FIG. 3 in the same projection as the sketch of FIG. 3.

The basic element of the subject drainage grid is a longitudinal strip 1. This can be made of an extruded profile or a profile made by bending the sheet. In the case of an extruded profile, its cross section is a triple stretched Z profile, but if the base is sheet metal, it is transformed into an L profile with special finishing of the longer arm of the L profile (more on that below).

Regardless of which of the two variants is in question, the laths 1 are in the installed state so that they each form an asymmetrical ministry. The laths 1 follow each other in a uniform manner in a fitting state and are so arranged that the upper lane of the Z profile is placed on the web of the previous Z profile or the shorter limb L of the profile is placed on the longer limb of the previous L profile, with the ridges of the profiles on one the sides and their bases on each other are aligned with each other.

The first in a series of longitudinal laths is fitted with a special support longitudinal lath 2. This, in the drawn 45-degree (but not the only possible) version, is also an L profile, which is mounted normally in the built-in condition with its shorter leg below and the upper edge of the longer limb located in the ridge itself between the upper lane and the web, in the case of the Z profile, or between the arms, if it is the L profile, of the first longitudinal strip. In an advantageous embodiment, the lath 2 is adapted to the custom lath 1 (regardless of the type of profile).

The last in a series of longitudinal battens, i.e. lath 3 differs from its previous ones in that it has a series of foot drainage cutouts 4 (details follow).

In the above defined uniform arrangement, the longitudinal battens are interconnected from below and supported by transverse positions or positions 5 (drawn only one, if necessary final), preferably one at each end of a series of longitudinal battens and, if necessary, i.e. depending on the system length and slenderness of the assembly, one or more in between.

The transverse position 5 is again essentially an L profile, so arranged that it is positioned so that its longer arm is used as a support for the longitudinal battens, and its shorter arm 6 facing upwards is located on the side of the object grid away from the stroke. roofs.

The upright shorter arms 6 and the lower arms of the L profiles of the transverse positions 5 are preferably freely inserted, with a thickness and length of the legs 6 adapted to a hinged sheet metal fence.

7. In the preferred design, the U profile is inverted. Its shorter arm forms essentially a continuous extension of a series of longitudinal battens, a concrete extension of the battens

3, and in its inbuilt state forms a groove of snowballs, i.e. a retaining railing from the roof of creeping (avalanche) snow, its longer, frontal limb extending below the level of the (not shown) edge groove of the roof gutter and forming an architecturally striking front wall of the assembly, which closes the height gap between the groove and the stroke towards the surroundings.

In the case of longitudinal strips of Z profile with a stretched cross-section (Fig. 1.3), the profile in question is so constructed that it is reasonably right angle between the upper lane and the profile stand, while the horizontal axis rotates as 45 °. 30 ° or whatever, can be completely any angle. Then the web and the lower band on the upper side are bracketed as 135 °, 150 °, etc.

In the case of sheet metal longitudinal battens (Figs. 2, 4), the longer arm L of the profile of each longitudinal molding, except the last one in the series, ie the molding 3, for the purpose of easy connection with the transverse positions 5 on its length sections coinciding with positions 5, from its free edge in the direction towards its corner edge, it is perpendicularly incised (Fig. 2) and the corresponding, thus formed, folded lengthwise section 8 is bent in a horizontal orientation in the installed position on the transverse position 5. In the case of the longitudinal lath 3, said horizontal length section (8) conveniently occupies the entire length of the lath, so that there is essentially no gap between the lath 3 and the shorter arm U of the profile of the railing 7. The lath 3 and the rail 7 thus form a mini-groove. To make it empty, suitable recesses are provided in lath 3. 1 there are no restrictions on the execution of cutouts of 4 different shapes and other locations.

It is understood that in order to avoid differences between the profiles, even if the slats are made of sheet metal, all slats, not just the last one (3), are formed as Z profiles.

It is also understood that the above angle information applies equally to sheet metal strips.

The assembly of longitudinal laths and enclosure 7 with the configuration shown above forms, in the floor plan, essentially a complete horizontal barrier to falling snowflakes. By attaching the proposed grille to the roof gutter, the basic inventive goal of keeping the gutter snow-free is thus achieved.

The invention subproblem, i.e. water discharge is solved according to the invention as follows.

As can be seen from the sketch of FIG. 3, the upper lane Z of the profile or the shorter arm L of the profile of the longitudinal laths (except the first one) is provided with cutouts 9, of which there are material bridges 10. (Snowflakes may fall through the cutouts 9, but are subsequently retained by the lower lath.) the meteor water is allowed to travel freely down into the groove located below the grid.

In the case of t.i. lightweight lattice designs, when the longitudinal laths are generally sheet metal, it is proposed to make them as shown in FIG. 4 (thick contour line illustrates sheet thickness). The corner section 11 of the bridge 10 is folded in into the space below the longer arm L of the profile and the trapezoidal space bridge 10 thus formed is positioned in such a way that, with its three-legged broken edge, it fits with its entire length on the pad.

For the interconnection of the components of the lattice in question, various well-known silo-and-sine joints are considered. Since they are known in the art, I give up their description.

The connection of the grid in question to the roof gutter shall include connection elements (indicated only in Fig. 1). For the connection with a standard sheet groove (here taken as an embodiment), one having a flap along its inner edge and a bulb facing outwards along its outer edge, the grid in question is, in its transverse positions 5, appropriate for all on both ends, fitted on the inside with an elastic feeder hook 12 and on the outside with an elastic snap tongue 13. First, when attaching the grille to the groove, we tuck it under the tab of the groove and the second together and simultaneously with the lower end of the outer arm U of the profile of the enclosure 7, by which they mutually form an elastically-fed split-snap pair, we push it down through the groove of the groove.

The installation of the grid in question on the gutter does not imply any changes in the installation and course of the gutter, which otherwise follows the physics of gravity flowing rainwater from the roof into the gutter and draining it down the gutter.

Within the framework disclosed above, a number of embodiments are offered to the person skilled in the art, which, although not explicitly shown, is covered by the claims which follow this description.
