Description
Technical Field
The utility model relates to the technical field of civil and architectural engineering, in particular to application of a curtain wall system, a waterproof coiled material and the like in a waterproof structure of a curtain wall.
Background
The enclosure structure divides the interior and the exterior into two different climatic environments. The introduction of equipment such as heating, refrigerating, and air exhausting makes the indoor environment relatively mild and controllable, for example, the indoor environment is preferably at a temperature of 20-26 ℃ and a relative humidity of 40-60%, and the outdoor environment is more dependent on the change of natural conditions. In principle, water vapor tends to diffuse from the high content side to the low content side. In the sea, the refrigeration time is long all the year round, and in plum rain seasons, outdoor rich water vapor diffuses indoors through the wall body, and condensed water accumulation is easily formed when the outdoor cold wall body is encountered. In contrast, the whole year heating time of the Harbin is long, indoor relatively damp and hot gas tends to penetrate through the wall body to diffuse to the outdoor side in winter, and condensed water also occurs in the cold wall body. The condensation mechanism the absolute humidity of the air is closely related to the temperature and relative humidity of the air. The accumulation and diffusion of condensed water in the wall body can influence the heat insulation performance of the outer wall heat insulation layer, and the problems of metal corrosion, wall body falling, mildew breeding and the like are easily caused.
In the prior art, an envelope structure usually includes curtain wall structures, and the method is divided into an open curtain wall and a closed curtain wall. A2 cm gap is reserved between the outer decorative plates of the open type curtain wall, sealing is not performed, and a waterproof system is additionally arranged in the open type curtain wall. The curtain wall outer plate heat insulation structure has the advantages that the problems of deformation, leakage and the like caused by expansion with heat and contraction with cold of the curtain wall outer plate can be effectively solved, and the heat insulation effect of the curtain wall can be effectively improved due to the ventilation performance of the air inside and outside the outer plate. The current waterproof practice is to install a metal waterproof sheet inside the exterior trim panel. However, the problem of dew condensation of the heat-insulating layer is difficult to solve by the scheme, the waterproof problem can be solved by the waterproof board, and a large amount of air exists in the waterproof board and the heat-insulating layer, so that condensed water is generated due to the change of air temperature, the heat-insulating layer is wetted, and the service life and the effect of the heat-insulating layer are influenced. In addition, the metal waterproof sheet does not have a reflective heat insulation effect, but generates high-intensity heat radiation due to its characteristic of being easily heated, resulting in an increase in indoor temperature.
The outer decorative plates of the closed curtain wall are filled with silicone weather-resistant glue and are sealed mainly by the glue. However, the system is easily affected by expansion with heat and contraction with cold of the outer plate to deform, so that sealant cracks, water seepage of the curtain wall is caused, and the heat insulation system is damaged. The common practice for solving the water seepage is to lay a waterproof coiled material (or a waterproof cushion layer) outside the heat-insulating layer. However, a waterproof structure reaching B1 level is not available in the market at present, the danger caused by curtain wall fire is huge, and the conventional materials have huge hidden dangers.
The first technical problem to be solved by the utility model is how to improve the waterproof capability of the curtain wall, and the second technical problem is the fire problem, the dewing problem and the heat insulation problem.
