Figure 2 is a perspective view showing an embodiment of a prefabricated insulating door according to the present invention, Figure 3 is a horizontal cross-sectional view thereof.

As shown, the insulating door of the present invention has an appearance similar to that of a door that is normally installed inside or outside of a building, and a prefabricated structure in which the front plate 110 and the rear plate 120 are coupled through an intermediate frame 130. Has The thermal insulation door of the present invention can be applied to a door structure having various opening and closing structures such as a sliding door and a liftable door, but in the illustrated embodiment, the door structure is coupled to the door frame 101 by a coupling means such as a hinge to rotate open and close. Example applied to.

The front plate 110 and the rear plate 120 to form the front and rear of the door, it may be made of a metal material, such as a steel sheet commonly used, in some cases may be made of a synthetic resin material.

Coupling parts 111 and 121 are coupled to the front plate 110 and the back plate 120 to the intermediate frame 130 along the periphery, respectively. The coupling parts 111 and 121 may be formed in various forms according to the materials and structures of the front plate 110 and the rear plate 120, but in the illustrated embodiment, each of the “a” and “c” shapes. Consists of a bent end to exemplify a simple structure and easy assembly.

The intermediate frame 130 is installed in the form of the outer frame of the door along the circumference of the front plate 110 and the rear plate 120 to indirectly couple both coupling parts 111 and 121, the front plate ( After placing the intermediate frame 130 between the 110 and the back plate 120, a plurality of coupling grooves (131, 133) in a form corresponding to the coupling portion (111, 121) on both sides so as to simply press or push to combine; ). The coupling grooves 131 and 133 may be formed in various shapes and positions according to the shape and position of the coupling portions 111 and 121. In the illustrated embodiment, the "c" shaped coupling portion of the front plate 110 is provided. The coupling groove 131 into which the 111 is inserted is formed in the side portion, and the coupling groove 133 into which the “a” -shaped coupling portion 121 of the rear plate 120 is inserted is formed in the rear portion. In addition, the same as the front plate 110 may be provided with an additional coupling groove 135 to couple the back plate having a "c" shaped coupling portion 111.
