Description

Technical field

The technical solution relates to a maintenance-free gutter system, in particular to the guttering of gutters for maintenance-free gutters, which do not require any year-round maintenance.

Background Art

In the overwhelming majority of the drainage of sloping roofs, gutter gutters are used, most often undercuts, rarely gutters or roof gutters. All types of troughs need to be maintained differently depending on the season. In the spring, summer and especially in the autumn it is necessary to protect the gutters from clogging or clogging of fallen leaves and small impurities by the so-called “dirt barrier” by means of protective nets or grates. In their absence, the troughs must be regularly checked and cleaned. In winter, they can become blocked by snow blowing, thawed snow freezing, and hanging icicles on the edge of the gutters. In part, these gutter defects can be eliminated by incorporating heated cables on the bottom and on the gutter walls.

The problem is that dirt barriers work well in the warm season without snow, but in winter they fall into the snow and dangerously hanging icicles form at the edge of the gutters.

Conversely, heated cables in the trough ensure their freezing in the winter, but by placing them in the trough they prevent the free flow of water and thus reduce the flow capacity of the troughs. If the heated cables are inserted into the troughs without dirt, ie nets or grids, they can cause the catching of leaves and debris along the entire length of the trough, thereby increasing the risk of blockage.

The essence of the technical solution

The current drawbacks of the known rainwater drainage systems for sloping roofs largely eliminate the maintenance-free gutter system of the invention. This maintenance-free gutter system consists of a trough over which a protective mesh is placed, where the protective mesh is attached to the roof supporting structure by the first side. The essence of the technical solution is that transverse supports are placed above the trough, which are anchored to the edge of the trough and to the supporting structure of the roof. On the transverse supports, a sleeve is arranged parallel to the trough, in which at least one heating cable is laid. According to a preferred embodiment, the protective mesh is attached to the housing by the other side. According to another advantageous solution, a free gap is formed between the end of the trough and the sleeve, usually in the range of 1 cm, which protects the trough from overflowing of water in case of extreme rain. In terms of durability, the transverse supports and the housing are made of aluminum.

The advantages of the technical solution can be summarized in several points:

- the trough is protected against dirt in summer and against dirt and freezing in winter

- the housing, in which the heated heating cables are stored, protects them from the degrading effects of UV radiation and increases the heating effect around the heating cable by its conductivity

- the transverse supports secure the gutter to avoid it and deform it due to snow loads, especially in mountain areas.

- the heated heating cables are in the area of the protective mesh, ie the heat from them is transferred to the aluminum housing and the adjacent surface of the protective mesh, in winter the protective mesh does not freeze, so the water flow to the trough is not reduced and dirt is not trapped in the trough.

- the free gap between the casing and the trough edge protects the troughs from overflow in the event of extreme rain.

- The proposed gutter system does not require year-round maintenance.

Drawing clarification

The technical solution will be explained in more detail with the help of pictures on which:

FIG. 1 shows a view of a maintenance-free gutter system

FIG. 2 is a sectional view taken along line A-A of FIG

Example of a technical solution

The maintenance-free gutter system 10 of FIGS. 1 and 2 is formed by a trough 1 fixed to the roof support structure 6 below the roof covering end 5. Aluminum transverse supports 3, which are anchored to the first side 3.1, are located above the trough 1 at a distance of about 50 cm. the roof support structure 6 and the second side 3.2 are anchored to the trough 1.1 edge 1. An aluminum sleeve 4 is attached to the transverse supports 10 and extends parallel to the trough along its entire length.

The aluminum housing 4 accommodates one or more heated heating cables 8 which heat the housing 4 over its entire length and width 4.1, thereby transferring heat to the adjacent surface of the protective net 2 which covers the trough i. 1 is attached to the roof support structure 6 and is attached to the housing 4 by the second side 2.2. A free gap 7 is formed between the end of the channel 1 and the housing 4, the width of which is approximately 1 cm. This free gap 7 protects the trough 1 from overflowing water in the event of extreme rain.
