Description

Building insulation{Insulation for structure}

In the present invention, an internal insulating sheet formed by forming a plurality of air layers and a building insulating material formed by forming an external insulating sheet on the surface of the inner insulating sheet are installed on the walls of various buildings to improve the thermal insulation and flame retardant effect of the building. ·It is related to the insulation of buildings with cold insulation, sound insulation and condensation prevention, and quasi-noncombustible material performance.

In general, fine pores exist in the concrete or brick used for the exterior wall of a building. Through the pores of the structural member, heat, cold air or draft supplied from the outside of the building flows into the interior or exits from the interior to the exterior.

As a result, the interior becomes hotter and humider in summer and colder in winter. To prevent this, various thermal insulation materials have been developed and marketed. However, the thermal insulation material developed to date has many problems in its materials and construction methods.

For example, styrofoam is most widely used because it is inexpensive and easy to purchase, but in the event of a fire, a large amount of toxic gas is generated, causing a lot of personal damage. In addition, styrofoam requires a separate finishing material such as plywood during construction, and there is a problem in that it takes a long time and labor cost burden.

Such problems are commonly seen in insulation materials manufactured based on petrochemical raw materials. On the other hand, glass fiber is excellent as a non-combustible building material, but it has a disadvantage of causing harmful side effects to the human body such as respiratory system diseases or skin irritation due to dust generated during the manufacturing process and construction process.

On the other hand, as a metal used as a heat insulating insulating material, aluminum or aluminum alloy is usually used. However, aluminum and aluminum alloys are excellent in reflecting radiant heat at high temperatures, but have a disadvantage of quickly absorbing cold air at low temperatures.

In addition, aluminum has a large deterioration in heat shielding and thermal insulation properties at a temperature within 20°C at room temperature. Therefore, while aluminum has a large radiation heat shielding effect in summer, it is difficult to apply to buildings in areas with distinct four seasons because it has a heat insulation effect only when the indoor temperature is maintained at room temperature 20°C or higher in cold winter.

In order to construct a conventional thermal insulation material on the wall of a building, there is a problem in that the construction method is difficult and complicated due to a separate subsidiary material, and the construction period is long, as well as material and labor costs are excessively consumed.

In addition, since the conventional thermal insulation material increases in volume due to subsidiary materials, the interior area (or space) of the building is reduced after construction. In addition, since the conventional thermal insulation material is made of a material that is bulky and fragile, it is easily damaged during transportation, resulting in excessive logistics costs and a problem that requires attention in handling.

Therefore, efforts to overcome the technical limitations of the conventional thermal insulation material have been steadily progressed in the related industry, and as a conventional insulation material invented under this background, as shown in FIG. 1, Korean Patent No. 10-1290455 Interior and exterior insulation materials for buildings and a method of manufacturing the same are provided, and its configuration is as follows.

In the above configuration, the foamed resin 51 in the building insulation according to the present invention, as shown in FIG. 4, is a foamed resin 51 having an elastic force formed so that the through spaces 51a forming an air layer are connected in a longitudinal and transverse direction. The reason for the formation of the through space 51a forming the air layer is to improve the effect of sound insulation as well as sound insulation due to the air layer.

And the reason for using the foam resin 51 having an elastic force is to facilitate the formation of the through space and to absorb the impact applied to the outer wall of the building.

The through space 51a forming the air layer of the foamed resin 51 as described above is formed in a rhombus shape, because the air layer is formed when the insulating sheet 53 described below is stacked in a plurality of layers.
