Embodiment Construction

[0029] The use and installation requirements of the present invention are: the base of the double-row bucket is installed in the roof structure, and the installation position is close to the exhaust pipe of the kitchen and bathroom. The distance between the outer walls of the two is about 600mm. Below the roof insulation board, if the cover board affects the laying of the roof insulation board, tools can be used to cut off the affected part of the insulation board. It is advisable to loosely lay the insulation board, and then lay an additional layer of 1 m above the double-row bucket 2 An additional layer of insulation board of appropriate thickness on the left and right. Note: The height of the exhaust cylinder from the roof must ensure that the distance between the steam outlet and the waterproof protective layer is more than 600mm. In the building with a suspended ceiling design in the top room, the structural slope layer is not required, and the closed water test of the ste...

Abstract

The invention discloses a roof drainage and steam exhaust device, namely a double-row hopper. The double-row hopper is mainly applied to a roof waterproof heat-preservation drainage and steam exhaust system, and aims to solve the problems that accumulated water in a roof heat-preservation layer cannot be discharged in time and moisture is slowly discharged. The double-row hopper is composed of a base and a cover plate, the base is installed in a roof structure, a cover plate supporting column is downwards installed on the base, the lower end of the base is connected to an indoor kitchen and toilet exhaust funnel, the lower end of the exhaust funnel is connected with a sewer pipe net, and the upper end of the exhaust funnel is higher than the roof and communicates with the atmosphere. When accumulated water in the roof heat-preservation layer is too large, the double-row hopper discharges the accumulated water in the heat-preservation layer through sewer pipe nets of kitchens and toilets, and when accumulated steam and pressure exist in the roof heat-preservation layer, gas can enter the double-row hopper through gaps of an extruded sheet and is discharged into the air through the exhaust funnel.

Description

technical field [0001] The invention relates to a drainage and steam exhausting device - a double-row bucket, which is mainly used on building roofs to discharge accumulated water and moisture in the roof insulation layer. Background technique [0002] According to 4.4.5 of "GB50345-2012 Roof Engineering Technical Specifications", the roof exhaust structure should meet the following requirements: [0003] (1) The grid joints set on the leveling layer can also be used as steam exhaust channels, and the width of the steam exhaust channels should be 40mm; [0004] (2) The steam exhaust duct should be connected vertically and horizontally, and should be connected with the exhaust steam pipe connected to the atmosphere. The steam exhaust hole can be set under the cornice or at the intersection of the vertical and horizontal exhaust steam ducts; [0005] (3) The vertical and horizontal spacing of the steam exhaust duct should be 6m, and the roof area should be 36m 2 It is advisa...
