Description

The invention relates to the field of construction, in particular to methods and devices for collecting rainwater from the pitched roof of a building.

It is known that rainwater drainage from a pitched roof is carried out using various drainage systems, which, despite their differences in the properties of materials and structural features of the constituent elements, generally include [1, p. 511-532] funnels, gutters, elbows, drainpipes, connecting elements, plugs, brackets, etc. In them, all the rainwater, as a rule, is directed to the blind area of the building or the roadway of the street and, as a result, to storm sewers. Moreover, in the drainage system PLASMO [1, p. 515] there is an inlet in the form of a tray, placed in the area accessible to the subject, to divert the drain from the drainpipe. However, this requires overlapping the drainpipe with the cover of the catchment basin during the period of rainfall and, as a result, leads to large dynamic loads of the elements of its fastening to the walls of the building and does not allow the accumulation of rainfall in an autonomous mode. The latter is planned to be eliminated in the proposed technical solution, according to which no close analogue has been identified.

The objective of the invention is the collection of rainwater from a pitched roof in the area of its manifestation while simplifying the drainage system from it as a whole. This is achieved by the fact that in the method for collecting rainfall along the edges of the roof of the roof using load-bearing elements in each frontal area near the cornice, the buildings are placed by attaching devices in the form of a storage tank of a given volume to them and each of them is connected together as communicating vessels, and as runoff accumulates in them, it is removed as a natural resource for its intended use. In another embodiment, the method is characterized in that flexible load-bearing elements, for example, cables, are used as load-bearing elements for securing the storage containers, and they are placed U-shaped with a given step along the building motionlessly resting on opposite walls of the building with symmetrical loading of their hanging parts with walls from storage tanks attached to them through the hinged brackets from the front sides of the building, i.e. according to a pattern similar to the arrangement of two goods on the beam. In addition, its difference lies in the fact that drainage is collected from the sides of the roof of the building by directing it from the edge of the roof of the roof to the gutters, and then from them to one of the storage tanks located in the front areas of the building. The device for collecting rainwater from the pitched roof of the building itself is a spatial thin-walled prefabricated beam structure of at least the length of the building, consisting of separate hermetically connected sections of a given section, for example, a trough, and made of a material resistant to environmental factors, and coated with arched mesh covers when it is formed as a whole in the form of a storage tank. In addition, it is equipped with a float type device to avoid overfilling with drain from the roof of the storage tank together with a pipeline for its disposal and a drain pipe to remove the accumulated drain in it.

The achievement of the technical result according to the task of the invention is a logical consequence arising from objective connections and interaction between the drain from the roof edge and the device for collecting it in the form of a storage tank.

In FIG. 1 is a structural diagram of the connections of the constituent elements of a device for collecting rainwater from the pitched roof 1 of building 2, which includes fixed flexible supporting elements 3, for example, cables, placed U-shaped along the building 2 with a given step and resting on its walls, and to the hanging their parts along the walls of the front sides of the building 2 are installed by hanging through the hinged brackets storage tanks 4 and 5. The collection of rainwater from the sides of the pitched roof 1 is carried out through the chute 6 with its direction in one of the storage x tanks 4 and 5. In this case, the storage tanks 4 and 5 are interconnected by a pipeline 7 as communicating vessels. Each storage tank 4 and 5 is a thin-walled structure of a beam type of trough-shaped section coated with arched mesh covers 8 to avoid clogging, and the dimensions of its section and volume as a whole are determined by the type and location of building 2, the conditions of accumulation and expenditure of rainfall, the intensity and periods of loss rainfall and the fullness of their use, etc. In addition, it contains a float-type device to prevent overfilling with rainfall, together with a pipe a breeder 9 for its disposal, and a drain pipe 10 to remove the accumulated drain in it. The float-type device itself is separated in the storage tank through the mesh grid 11 and consists of a valve 12 overlapping its drain hole and a float 13 connected to the valve 12 by a flexible thread-like element 14, for example, a chain of a given length.

As an example of the implementation of this technical solution, we consider the collection of a rain gutter as applied to a gable roof, taking into account the following initial data: roof area in terms of S _k = b⋅l = 12⋅50 = 600 m ² ; working cross-sectional area of the storage tank S _H = b ₁ ⋅h ₁ = 0.2⋅0.3 = 0.06 m ² ; the level of rainfall in one period h ₀ = 10 mm Then the volume of runoff from the roof will be V _K = S _K ⋅h ₁ = 600⋅0.01 = 6 m ³ , and the total volume of two storage tanks is equal to V _H = 2S _H ⋅l = 2⋅0.06 =50 = 6 m ₃ . Therefore, with the equality V _K = V _{H, the} entire drain from the roof will be preserved in storage tanks 4 and 5, as necessary, used as a natural resource for its intended purpose, for example, for irrigation of plants by gravity through pipeline 10.

This invention can be successfully applied in the case when precipitation in the form of snow falls on the roof and drainage when they melt is carried out without drain from the roof, for example, based on a technical solution [2].

The advantages of this technical solution are: ensuring the collection of rainwater from the roof in the zone of its manifestation and the possibility of its disposal by gravity; simplification of the drainage system as a whole.
