CZ32023U1 - A maintenance-free gutter system - Google Patents

Description

Technical field

The technical solution concerns a maintenance-free gutter system, especially the treatment of guttering gutters to maintenance-free gutters, which do not require their year-round maintenance.

BACKGROUND OF THE INVENTION

For draining rain water at sloping roofs, the vast majority of them use perimeter gutters, most often under-gutters, and rarely roof or gutter gutters. All types of troughs require maintenance depending on the season. In spring, summer and especially in autumn, it is necessary to protect the gutters from clogging or clogging of fallen leaves and small impurities by means of “mesh protection” using protective nets or grates. In the absence thereof, the troughs must be inspected and cleaned regularly. In winter, they may become clogged due to blown snow, freezing of thawed snow and the formation of hanging icicles on the edge of the troughs. In part, these gutter defects can be eliminated by installing heated cables on the gutter bottom and walls.

The problem is that the dirt barriers work well in a warm, snow-free period, but they fall in snow in winter and dangerously hanging icicles form at the edge of the gutters.

Conversely, heated cables in the trough ensure that they do not freeze in 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 heated cables are inserted into the troughs without dirt restraint, ie nets or grates, they can cause the trapping of leaves and dirt along the entire length of the trough, thereby increasing the risk of blockage.

From CZ Utility Model No. 29029 a maintenance-free gutter system is known, the disadvantage of which is that the heating cable cannot be replaced or retrofitted from the roof.

The essence of the technical solution

The existing disadvantages of the known rainwater drainage systems for pitched roofs are largely eliminated by the maintenance-free gutter system according to the invention. This maintenance-free gutter system consists of a gutter terminated by an end part (bead), the gutter being attached to the roof structure.

The essence of the technical solution is that a shaped supporting and filtering element (mesh) is attached to the roof supporting structure, which is located above the eaves gutter. This shaped support and filter element has an open triangle recess in the end portion with a continuous flat surface. The end part (bead) of the eaves gutter is connected to the flat surface. According to a first preferred embodiment of the invention, a recess is provided in the recess, which is covered by a removable top guard. According to a second preferred solution, a heated heating cable is arranged between the lower cover and the upper cover. In view of the thermal conductivity for transferring heat from the heating heated cable to the support and filter elements, it is preferable to provide this element including a lower cover and an upper aluminum cover.

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

- when using the system only with a shaped support and filter element with a recess, so the dirt settles in this recess and thus protects the trough from clogging

- 1 GB 32023 U1

- when using the system with a heated heating cable placed between the bottom and top cover in the recess, the trough does not freeze in winter

- the aluminum cover, which houses the heating cable, protects the cables from the degrading effects of UV radiation and its conductivity increases the heating effect around the heating cable and thus better heat transfer to the adjacent surfaces of the gutter and the supporting and filter element, it does not freeze and does not reduce the water flow to the trough and does not trap dirt in the trough.

- design without the use of a heated heating cable

- the submitted gutter system solution does not require year-round maintenance.

- the heating cables are replaceable during their operation and can be retrofitted after the top cover has been removed.

Example of technical solution implementation

The maintenance-free gutter system with the heated heating cable 4 according to FIGS. 1 and 2 consists of a gutter 5 with an end portion 5.1 (bead), the gutter 5 and the roof covering 8 being anchored to the wooden roof support structure 10. A shaped support and filter element 1 is fastened to the timber support structure 10 by bolts 7, which serves as a support and filter element (mesh to prevent the entry of larger impurities into the gutter 5). This shaped support and filter element 1 is positioned above the eaves trough 5. The shaped support and filter element 1 has an open triangle-shaped recess 1,2 in the end portion 1,1 with a wall angle of about 105 ° (Fig. 2). The recess 1,2 is connected by a flat surface 1,3 under which the end part 5.1 (bead) of the eaves trough 5 is guided, both parts being connected by the farmer's screws 6. The recess 1,2 houses the lower cover 2 of the heating cable 4 ( Fig. 3). The bottom cover 2 is made, for example, of aluminum sheet of thickness. 0.6 mm. The lower 2 cover is connected to a recess 1,2 by means of rivets (not shown). The heated heating cable 4 is housed in the lower cover 2. The heated heating cable 4 is a cover with a removable upper cover 3, which is e.g. 0.6 mm (Fig. 4). The top cover 3 is inserted between the shaped support and filter element 1 and the bottom cover 2 and the screws 6 are fixed to the gutter 5. The top cover 3 forms a plane with the support and filter element 7. The front wall of the roof is lined with a shaped cladding sheet 9 which extends under the roof covering.

According to another exemplary embodiment, the maintenance-free gutter system does not comprise a heated heating cable 4. In this embodiment, the support and filter element 1 is not fitted with a bottom cover 2 and a removable top cover 3 in the recess 1.2 (Fig. 2).
