Description

The invention relates to special devices, structurally associated with the roof, in particular to methods and devices for protection against avalanche snow and ice from roofs.

Known snow retention device according to US Pat. RU 2654881, application No. 2016139930 dated 10.10.2016, publ. 05/23/2018 Bul. No. 15 [1], consisting of supporting elements that hold snow and ice.

контуров.The fundamental difference between the claimed invention is that the elements retaining snow and ice are installed on the upper ends of the supporting elements made of

contours.

контуры крепятся на несущих конструкциях кровли под кровельным материалом.Bottom side

the contours are attached to the roof supporting structures under the roofing material.

The obvious advantage of the present invention, which is the prototype, is that the contact of the elements holding snow and ice with the outer surface of the roof is excluded.

элементам независимо от их конфигурации и опционального исполнения присущ один существенный недостаток.but

elements, regardless of their configuration and optional performance, have one significant drawback.

This disadvantage is predetermined by the radial or close to it transition from the top to the bottom at the border of the transition with the end of the roofing material.

The essence of the disadvantage is that due to the smoothness of the transition, as well as the natural physical phenomena of wetting, part of the moisture through the body of the element penetrates the roof lathing, moisturizes it and thereby reduces its durability.

In addition, this negative effect is enhanced by the so-called "licking" of the flowing moisture under the pressure of the wind.

To prevent this phenomenon, the prototype is provided in Item 23 of the formula and in FIG. 22 alternative solution to this problem by installing a barrier to prevent moisture from entering the roof sheathing.

As practice has shown, with all the efficiency achieved in preventing moisture penetration under the roof, the proposed solution has fundamental disadvantages.

Firstly, when installing a curb made of non-metallic materials, they have to be coated together with the supporting element, but with a galvanic coating such as hot-dip galvanizing, this is not possible.

Installation of split options requires special production of borders with the need to use some kind of clamps, ties, etc., which increases the cost of the structure.

Secondly, when installing welded borders on bends, the profile contour is deformed from the effect of temperature, therefore, after welding, the product has to be subjected to an additional laborious operation of straightening and leveling.

Thirdly, it is very difficult to set practically the same contour of the profile of the supporting element by bending even within the same batch of rolled products due to the unpredictability of the spring effect in the deformation area and the subsequent relaxation of each product, especially during the subsequent coating of the product by hot-dip galvanizing.

The aim of the present invention is to provide the elimination of the above disadvantages by constructive improvement of the support element.

The achievement of this goal is disclosed in the following figures with their subsequent explanation, which is the subject of the claims.

Mauerlat 2 is installed on wall 1, to which the roof rafters are attached 3.

A windproof board 4 is sewn onto the rafters 3, on top of the windproof board 4, with a certain pitch, slats 5 are nailed with fastening through the board 4 directly to the rafter leg 3.

Roofing, for example, wave material 6, is installed on the slats 5.

In a variant version, the gutter bracket 7 is attached to the boards 4, in which the gutter 8 is fixed.

изогнутого контура 9.2 так, что нижний конец контура находится ниже или как минимум заподлицо с нижним краем свисающей части консоли.The supporting element 9 consists of a supporting arm 9.1, the hanging end of which is rigidly connected with a straight bent part

curved contour 9.2 so that the lower end of the contour is below or at least flush with the lower edge of the hanging part of the console.

изогнутого контура 9.2 может находиться в интервале от 45 до 120 градусов, но преимущественное исполнение в пределах 90 град.The angle of the joint between the console 9.1 and the folded part

curved contour 9.2 can be in the range from 45 to 120 degrees, but the preferred design is within 90 degrees.

изогнутого контура исключает с одной стороны плавность перехода от верхней части

изогнутого контура в подкровельное пространство, а с другой удлиняет вынос от торца обрешетки до точки схода стекающей влаги.Such an angled connection with a sharp transition at the point of contact of the overhanging part of the console and the lower straight end

curved contour eliminates smooth transition from the top on one side

a curved contour into the under-roof space, and on the other, it extends the extension from the end of the sheathing to the vanishing point of the flowing moisture.

Even if, in the case of wind pressure, the licking effect appears, then due to the increased distance from the vanishing point to the end of the sheathing, the negative effect will be minimal.

The main effect of the dangling end will be manifested in that. that due to surface tension moisture flowing down vertically along the hanging end will reduce the effect of wetting and the intensity of moisture penetration under the roof along the inclined part of the console.

изогнутого профиля.Technologically, the process of joining two fixed parts of the support element occurs at the end of the hanging end of the console by welding with a straight undeformed section of the bent end

curved profile.

In this case, no noticeable temperature violations of the geometry of the welded contour are observed even during the subsequent hot-dip galvanizing of the product.

изогнутого контура закрепляется удерживающий снег и лед элемент 10 в вариантных исполнениях [1].At the end of the upper part

of the curved contour, the snow and ice retaining element 10 is fixed in variants [1].

изогнутого контура можно усилить Фиг. 2, например, путем стыковки на прямой недеформированной отогнутой части свисающего конца консоли с нижней части

изогнутого контура, но при этом возможно проявление эффекта пружинения описанного выше.The effect of water discharge at the junction of the console and

the curved contour can be reinforced. FIG. 2, for example, by joining on a straight undeformed bent part of the hanging end of the console from the bottom

a curved contour, but the appearance of the springback effect described above is possible.

In the absence of a gutter, direct the water drain downwards without spraying drops and a jet by the wind, the hanging end of the support element, in a variant version, can be equipped with a loop for fastening the chain 9.3.

изогнутого контура может соединяться со свисающим концом консоли с помощью любого разъемного соединения, например, Фиг. З с помощью втулки 11, постоянно связанной со свисающим концом консоли 9.1.In order to facilitate the technology of mounting the snow-retaining device, the bent part

the curved contour can be connected to the hanging end of the console by any detachable connection, for example, FIG. З with the help of the sleeve 11, which is permanently connected with the hanging end of the console 9.1.

изогнутый контур из цветного металла - бронзовый, медный, дюралевый и т.д. вплоть до пластиковых композитных материалов, как однородных, так и армированных. При этом

изогнутый контур, вставленный во втулку 11, может иметь на конце отогнутой части резьбовой конец 12 и фиксироваться гайкой 13.In this case, it is possible to use various combinations of materials without losing the bearing capacity of the supporting element, for example, the console can be steel or cast iron, cast, and

curved contour made of non-ferrous metal - bronze, copper, duralumin, etc. up to plastic composite materials, both homogeneous and reinforced. Wherein

The curved contour inserted into the bushing 11 can have a threaded end 12 at the end of the bent part and be fixed with a nut 13.

The most important element of any roof is a gutter that allows water to drain from the roof. Gutters of any configuration are installed on special brackets (see, for example, [2]).

The overwhelming majority of gutter brackets are usually fastened with screws or nails to the roof sheathing under the roofing material.

Installation of brackets requires a certain investment of time and materials, complicates the technology of roof construction, caused by the need to bend each bracket to its size in accordance with the slope of the gutter.

It is possible to simplify the task and improve the manufacturability of the installation work in the light of the present invention by installing a mounting element on the hanging end of the console for attaching the gutter bracket.

In a variant version, it may look like this:

To the hanging end of the cantilever 9.1 of FIG. 4 welded at the bottom, for example, a carrier strip with a groove 14.

The gutter bracket 7 also contains a similar strip 15 with an elongated groove, but of a slightly shorter length.

Both strips are pulled together with a bolt 16 at the desired overhang and with the desired slope for the gutter.

The installation process is very simple and versatile.

In addition, the direction of water flow can very easily change, which is very valuable for private households when changing from winter to summer and vice versa. For example, in the summertime - to the garden to collect water for irrigation, in winter - to the street.

Instead of slotted strips, round or profile rods can be used, pulled together by clamps, threaded or telescopic connections, their various combinations, etc.

Option of detachable connection of the hanging end of the console and the gutter bracket.

Alternatively, Fig. 5 may look like this:

To the hanging end 9.1 with a clamp 17, consisting of a threaded bracket 17.1 and a strip 17.2, the bent part of the gutter bracket 7 in the right place is attracted to the hanging end of the console 9.1.

The height of the wave roofing material can be different and in some cases it may not be possible to select the required height, the cross-section of one rod of the bearing console from the condition of the required strength.

изогнутый контур любого вариантного исполнения может быть вварен или вставлен разъемным способом между стержнями и притянут гайкой 13.In such a case, FIG. 6, the support arm can be, for example, a double-rod 18 or a universal always double-rod, and

the curved contour of any variant can be welded or inserted in a detachable way between the rods and tightened with a nut 13.

With this option, the carrier strip of the removable mounting element of the gutter bracket 14 could be removable and versatile.

In this embodiment, a bolt 19 is welded to the support bar 14, which is inserted between the rods of the console 9.1 and is attracted to it by the nut 20 at the desired overhang location.

Thus, the proposed technical solution ensures the achievement of the specified object of the invention, is easily applicable in practice, and has increased versatility.
