Abstract

FIELD: construction engineering. SUBSTANCE: drainage system includes water collecting troughs with drain holes arranged on edges of roof. Connected to drain holes are drain pipes. Drainage system also incorporates system for heating zone where drain holes are located. Additionally provided are internal water draining pipes. Heating system is made in the form of enclosed metal heat-conserving shell separated from external surface of draining pipe. There are pipe connections for passing return water from heating system of building. Aforesaid embodiment of drainage system is of increased reliability in operation. EFFECT: higher efficiency. 1 dwg

Description

 The present invention relates to construction and can be used in coatings of multi-storey buildings.

 Known drainage system for the sloping roof of a multi-storey building, including drainage trays located on the edges of the roof with drain holes and pipes of the internal drain (see AS USSR N 798259, class E 04 D 13/04).

 A disadvantage of the known solution is the lack of heating of the drainage area, which can contribute to overflowing of drainage trays with melt water in the early spring due to the formation of ice plugs in the drainage holes.

 The closest technical solution to the proposed invention is a drainage system for the pitched roof of a multi-storey building, including drainage baskets placed along the edges of the roof with drain holes and drain pipes adjoining them, a heating system for the drain hole zone, and an internal drain pipe. In this case, the heating system is made in the form of a return heating pipe placed under the bottom of the drainage tray (see the project “Sloping roofless roof and inclined enclosure of attic rooms from flat expanded clay concrete slabs with a decorative relief. Technical solutions. OJSC TsNIIEP dwellings, M, 1996, l. nine).

 The heating system in this solution is not effective enough due to large heat losses, which affects the drainage performance.

 The purpose of the proposal is to increase the reliability of the drainage system.

 This goal is achieved by the fact that in the drainage system for the pitched roof of a multi-storey building, including drainage trays located along the edges of the roof with drain holes and adjacent drain pipes, a heating system for the drain holes and an internal drain pipe, the water heating system is made in the form of a closed metal insulated shell spaced from the outer surface of the drain pipe with pipes for passing the return water of the building heating.

 The drawing shows a fragment of a section of a drainage system for a pitched roof with the attic floor of a multi-storey building located inside it.

 The drainage system for the pitched, predominantly mansard roof of a multi-storey building contains drainage trays 2 located along the edges of the insulated roof 1 with drain holes 3 and drain pipes 4 adjacent to them, as well as pipes of the internal drain 5. The drain pipe 4 is made with a closed metal spaced apart from its outer surface the shell 6 and is placed inside the element of the insulated roof 1. The shell 6 is equipped with an inlet 7 and an outlet 8 nozzles for passing back heating water, as well as a longitudinal partition 9 that improves the compass hot water along the pipe 4.

 Hot water from the return heating pipe 10 of the attic is passed through the shell 6, heating the drain pipe 4 and the drain hole 3, and then returns to the return heating pipe 10.

 The proposed solution quite simply and reliably increases the efficiency of drainage from the roof, preventing the formation of ice plugs in the area of the drain holes of the drainage trays.

Claims (1)

 A drainage system for the pitched roof of a multi-storey building, including drainage trays located at the edges of the roof with drain holes and drain pipes adjoining them, a heating system for the drain holes and an internal drain pipe, characterized in that the heating system is made in the form of a closed metal insulated shell spaced from the outer surface of the drain pipe, with nozzles for the passage of return water for heating the building.
