Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a building external heat insulating water retention device that is laid on the surface of a building, such as a roof or a roof, and suppresses a rise in the temperature of the building.
[0002]
[Prior art]
Traditionally, in addition to public facilities such as hospitals, nursing homes, hotels, and schools, buildings, convenience stores, supermarkets, private houses, and other buildings have internal insulation as a thermal insulation method that reduces the influence of external temperature (temperature). The method is adopted.
[0003]
[Problems to be solved by the invention]
However, in the internal heat insulation system, if the building is a steel structure or a steel rebar structure, for example, a heat bridge phenomenon occurs in which the external temperature is transmitted to the inside through the rebar of the slab. For this reason, the worst living environment that abnormally increases the indoor temperature in the summer and abnormally lowers the indoor temperature in the winter is created, and the air conditioning cost for adjusting the indoor temperature is increased. That is, in the conventional inner heat insulation system, since excellent heat insulation cannot be expected, there is a difficulty that energy saving of indoor temperature adjustment is hindered. In addition, condensation may occur in each part of the building, leading to the generation of toxic mold and corrosion of building materials, which may adversely affect human bodies and buildings.
[0004]
On the other hand, the surfaces of buildings such as roofs and rooftops are exposed to intense direct sunlight, especially in the summer, and thus deteriorate quickly. Moreover, the temperature change between day and night is large, and thermal expansion and contraction are repeated every day with a large amount of expansion and contraction. As a result, cracks occur on the roof and roof, causing rainwater to penetrate and adversely affecting the building, reducing the durability of the building.
[0005]
For this reason, it improves the durability of the building by demonstrating excellent light-shielding properties and heat insulation properties, improves the living environment, saves energy in adjusting the indoor temperature, and further simplifies construction and shortens the work period. Therefore, there is a demand for the development of a heat insulation method that can reduce running costs.
[0006]
The present invention has been made in view of such circumstances, improving the durability of the building by exhibiting excellent light-shielding properties and heat insulation properties, and improving the living environment to save energy in adjusting the indoor temperature. The purpose is to provide an external heat insulation and water retention device for buildings that can be realized, can be easily constructed, shorten the construction period, and can reduce running costs.
[0007]
