Description

Technical Field

[0001] The utility model relates to the technical field of building waterproofing, in particular to a drip line and a building structure. Background Art

[0002] The waterproof performance of the building's exterior wall system affects its own thermal insulation and durability. At normal temperature and pressure, the thermal conductivity of liquid water is about 0.59W / (m·K), and the thermal conductivity of air is about 0.026W / (m·K). The thermal conductivity of liquid water is much greater than that of air. If water freezes into ice in a low-temperature environment, the thermal conductivity of ice is about 2.2W / (m·K), so the overall thermal conductivity of the material will also increase. When liquid water invades the exterior wall system, the mechanical properties and durability of the exterior wall system will be greatly reduced under the environmental conditions of dry-wet alternation and freeze-thaw cycles.

[0003] The window sills, air conditioning panels and other structural parts of buildings are high-incidence areas of water seepage. If the water is not discharged in time, the water will pass through the insulation layer, resulting in indoor water seepage, reduced building insulation effect and other problems. At present, a drip line board is usually installed at the bottom edge of the insulation layer of the building's exterior wall to reduce the phenomenon of water diffusion in the insulation layer. In view of the above-mentioned technical phenomenon, the inventor believes that water can easily penetrate into the insulation layer and gather between the wall and the insulation layer, while the existing building drip line structure cannot drain the water between the insulation layer and the wall. Therefore, the inventor invented a drip line that can not only drain the surface water of the building, but also drain the accumulated water and moisture inside the building structure, and a building structure using the drip line.
