Background
The closed heat-insulating layer is a situation that the roof heat-insulating layer is positioned below the waterproof layer and is completely covered by the waterproof layer. Except for the inverted roof, the heat-insulating layer of the general roof belongs to a closed heat-insulating layer. The exhaust of the flat roof with the closed heat-insulating layer enables gas in the heat-insulating layer to be discharged in time, so that the roof is effectively prevented from being cracked and damaged due to frost heaving of water and pressure of the gas, and the service life of the roof is prolonged. However, in practical use, the problem of water seepage and leakage or the problem of moisture regain of the exhaust pipe often appear at weak node positions such as cornices and the like, so that the use is affected by the humidity of the roof.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide an exhaust cornice node structure of a flat roof with a closed heat-insulating layer, aiming at the defects and shortcomings of the prior art, the exhaust cornice node structure has the advantages that the moisture regain situation is reduced through a drip bent exhaust pipe, gas is effectively and timely exhausted, meanwhile, multiple waterproof effects can effectively prevent the influence of accumulated water on the exhaust pipe and the heat-insulating layer, and the service life is prolonged.
In order to achieve the purpose, the utility model adopts the technical scheme that: a flat roof exhaust cornice node structure for a closed heat-insulating layer comprises a flat roof, cornices, a slope-making layer, a leveling layer, an exhaust pipe, a waterproof roll material layer and a protective layer; the flat roof is of a reinforced concrete roof structure, cornices are built on the top of the flat roof to the outdoor layer, and cement mortar surface layers are built on the cornices, the bottom surface and the side surfaces of the flat roof; a slope layer is built on the top surface of the flat roof, and a heat insulation layer is laid on the top surface of the slope layer; leveling layers are built on the slope-finding layer, the heat-insulating layer and the top surface of the cornice, and the edges of the slope-finding layer and the heat-insulating layer are wrapped by the leveling layers; exhaust pipes which are arranged in a latticed manner and are parallel to the top surface of the flat roof penetrate through the leveling layer, are bent downwards at the edge position of the cornice and penetrate through the leveling layer, the cornice and the cement mortar surface layer; a waterproof coil layer is laid on the top surface of the leveling layer, and a reinforced waterproof layer is further laid between the waterproof coil layer and the leveling layer on the top surface of the slope-shaped leveling layer at the bending position of the exhaust pipe; the waterproof roll material layer is characterized in that a protective layer is built on part of the top surface of the flat roof corresponding to the waterproof roll material layer, the protective layer is a mortar finish coat, and a self-adhesive strip serving as a sealing structure is arranged between the edge of the protective layer and the waterproof roll material layer.
Preferably, the distance that the blast pipe runs through cement mortar surface course below the bottom surface is not less than 20mm, and the blast pipe bottom sets up to drip structure.
Preferably, the reinforced waterproof layer extends to the center of the leveling layer and the periphery along the slope-shaped leveling layer from the bent part of the exhaust pipe by not less than 300mm, and the edges of the reinforced waterproof layer and the waterproof roll layer are fastened and sealed.
The utility model has the beneficial effects that: this structure reduces the anti-tide condition through the blast pipe of the bending of dripping, and effective timely exhaust gas, multiple waterproof can prevent effectively that roofing ponding from to the influence of blast pipe and heat preservation, increase of service life simultaneously.
