(54) DRAINAGE SYSTEM FOR COATING BUILDINGS WITH EARNINGS

one

The invention relates to drainage devices that are structurally associated with the roof of buildings that have a cornice, and can be used in construction for the installation of coatings with internal drainage.

A drainage system for covering buildings with a cornice is known, including drainage trays located in the cold part of the walls and the eaves 1.

In a known drainage system, the walls and the eaves are relatively quickly destroyed during the operation of the building. Moreover, in the drainage device, the fall of ice growths from the eaves and walls is not excluded.

Also known is a drainage system for covering buildings with a cornice, which contains a water intake tray and heated pipes located outside the building 2.

Such drainage eliminates ice on the eaves and in the tray due to their heating. However, the known device does not provide drainage of rainwater, which create significant shock loads on the tray and the eaves, which impair their performance. In addition, the external location of the spill pipes requires a lot of heat for heating the pipes, the tray and the eaves.

Closest to the present invention is a drainage system for covering buildings with a cornice, which includes a water receiving tray with drain pipes / passing inside the building Z.

 Known drainage improves performance; however, it eliminates the formation of frost on the eaves and its destruction, as well as the impact on the tray and the eaves of shock loads of storm water, is provided on the roofs of buildings with a large length of the slope, on which the speed is large mass of water can reach 5 m / s.

The purpose of the invention is to reduce the cost of operating a building by preventing the formation of Hei eaves on the eaves and to reduce the consumption of drain pipes by discharging storm water from the floor to the outside.

The goal is achieved by the fact that in the drainage system for covering buildings 0 with a cornice including

the covering and the odor-receiving tray adjacent to the eavement with gutters running inside the building, the upper part of the eaves are made with a brotherly slope, and the receiving tray is provided with a curved ellipse with transverse slots covering it.

FIG. 1 shows a building with a cornice and a wall, cross section; in fig. 2 — node 1 in FIG. one; in fig. 3 is a view A of FIG. 2

The drainage system consists of a water intake tray 1 located in the covering 2 and adjacent to the eaves 3 installed above the wall 4. The water intake tray 1 has drain pipes 5 passing inside the building b. The upper part of the eaves 3 has a slope opposite to the coating 2, and the water intake tray 1 is blocked by a curved chute 7 with transverse slots 8.

During operation of the building coating, two options for water drainage are possible.

The water tal and low-intensity rain water moves along the covering 2 and the upper part of the eaves 3 to the water intake tray 1, getting into it through slots 8 of the curved chute 7. From tray 1 water flows into the drainpipe 5 and is discharged into the sewer (not shown) .

During heavy rainfall, a stream of high intensity rainwater can move along the long slopes of the coating at a speed of about 5 m / s. In this case, a small part of the water enters the tray 1 through the slots 8 of the chute 7, and then through the drain pipes 5 - into the sewer. The main flow of water that approaches the curved chute 7 slips through it and then drops down over the ledge 3.

The total area of cuts in the curvilinear gutter is determined by the condition of removal of melt water through them during spring operation, as well as rain water, the intensity of which corresponds to its duration of 20 minutes in a specific construction area. At the same time, to ensure the discharge of the main mass of water during showers of 23 minutes along the curved surface of the chute through the eaves, the width of the slits is 10-12 minutes, and the slope of the eaves, which is opposite to the floor, is 12-30%.

Making a cornice with a slope opposite to the coating provides water flow to the water intake tray during the snow, eliminates the formation of frost on the cornice, including its extreme section, which increases the reliability and durability of the cornice.

The gutter above the water intake tray, due to its curved surface, makes it possible to soften or completely avoid the impact effects of storm water on the water intake tray and the eaves, and also to accelerate the discharge of water from the floor to the outside.

Such a drainage design allows to significantly increase the length of the slope of the roof, simplify the building profile, eliminate height differences due to the device in multi-span single or double gable buildings.

coatings, which reduces the area of enclosing structures and reduces the length of the drainage pipes.

The invention can be used in the construction of buildings of the metallurgical industry, as well as objects of the USSR Ministry of Petroleum and Gas Industry.
