Double-layer waterproof and double-layer water exhaust structure of heat insulation house surface and construction method thereof

Abstract

The invention relates to a double-layer waterproof and double-layer water exhaust structure of a heat insulation house surface and a construction method thereof. The structure respectively consists of a reinforced concrete house surface layer, a bottom cement mortar leveling layer, a bottom waterproof layer, a heat insulation layer, a surface cement mortar leveling layer and a surface waterproof layer from bottom to top. Two sets of waterproof and water exhaust structures are arranged at the upper part and lower part of the heat insulation layer. A plurality of transversal and longitudinal gas exhaust channels are arranged on the bottom cement mortar leveling layer. House surface gas exhaust outlets are arranged in the cross parts of the transversal and longitudinal gas exhaust channels. House surface gas exhaust pipes are arranged on the house surface gas exhaust outlets. The constructing method has the following steps of: paving the house surface plate; respectively arranging the bottom cement mortar leveling surface to falls, the bottom waterproof layer, the heat insulation layer and the surface cement motor leveling layer to falls, and the surface waterproof layer on the housesurface plate; arranging the gas exhaust pipes of the house surface and the water exhaust pipes of the heat insulation layer, wherein the two water exhaust pipes are communicated with the water collecting part on the house surface, and the other ends are arranged in a water falling hopper; and communicating the water falling hoppers with the total water exhaust pipes. The invention solves the waterproof and heat insulation problems of the house surface, and has obvious waterproof and water exhaust effects.

Description

technical field [0001] The invention relates to a house waterproof and drainage structure and a construction method in the field of construction, in particular to a double-layer waterproof and double-layer drainage structure of a thermal insulation roof and a construction method thereof. Background technique [0002] Roof leakage is a common problem that plagues the construction industry. It is a problem that the people's government, industry and the general public are more concerned about. Various scientific research units and waterproof manufacturers have developed many new waterproof materials, and relevant units and departments have also summarized many. Waterproofing methods, but failed to eliminate roof leakage. The current thermal insulation roof waterproof system is divided into two forms: upright type and inverted type. The method of upright roof waterproofing is to do waterproofing on the insulation layer. The disadvantage of this approach is that if any part of t...

Problems solved by technology

[0003] Chinese patent 200710202498.X discloses "an air-introduced drainage system for thermal insulation and waterproof roof" whose structure is basically the same as that of the inverted roof waterproof structure, and does not fundamentally solve the problem that the protective layer of the inverted roof is easy to crack and leak, although it is in the insulation layer An air-inducing drainage pipe connected to the rainwater pipe was added to discharge most of the accumulated water trapped in the insulation layer, but it failed to fundamentally solve the roof leakage, and it also brought about a problem, that is, when the roof encounters When there is heavy rain, since the air-inducing drainage pipe in the insulation layer is connected to the rainwater pipe, the rainwater on the roof may flow back into the insulation layer through the air-inducing drainage pipe. In this case, the insulation layer may backflow in case of heavy rain Water ingress, causing roof leakage

In addition, the thermal insulation roof of this patent is not equipped with an exhaust pipe, which causes the water vapor in the roof insulation layer to be unable to be discharged.
