Formwork panel

Abstract

A formwork panel includes a heat insulating material forming one side of the formwork panel, and a support forming the other side of the formwork panel and detachably coupled to the heat insulating material, in which the size of the support corresponds to the size of the heat insulating material, and the support includes an edge part surrounding the opening part and having no opening, and the support includes an opening part having at least one opening such that, in a structure in which the support and the heat insulating material are coupled to each other, the heat insulating material is exposed to the outside.

1 . A formwork panel comprising:
 a heat insulating material forming one side of the formwork panel; and   a support forming the other side of the formwork panel and detachably coupled to the heat insulating material, wherein   a size of the support corresponds to a size of the heat insulating material,   the support includes an opening part having at least one opening such that, in a structure in which the support and the heat insulating material are coupled to each other, the heat insulating material is exposed to the outside, and   the support includes an edge part surrounding the opening part and having no opening.   
     
     
         2 . The formwork panel according to  claim 1 , wherein the opening part includes a mesh structure, a perforated structure or a truss structure. 
     
     
         3 . The formwork panel according to  claim 2 , wherein, in the structure in which the support and the heat insulating material are coupled to each other, the edge part supports the heat insulating material. 
     
     
         4 . A method for constructing a concrete wall using a formwork panel comprising:
 placing a first formwork panel, the first forming panel including a heat insulating material forming one side, and a support forming the other side and detachably coupled to the heat insulating material;   placing a second formwork panel having the same structure as the first formwork panel apart from the first formwork panel by a distance corresponding to a space where concrete is poured, with the heat insulating material of the first formwork panel and the heat insulating material of the second formwork panel facing each other;   pouring concrete into the space;   curing the poured concrete; and   separating the supports from the first formwork panel and the second formwork panel, wherein the support includes an opening part having at least one opening such that, in a structure in which the support and the heat insulating material are coupled to each other, the heat insulating material is exposed to the outside.   
     
     
         5 . The method according to  claim 4 , further comprising:
 placing a third formwork panel having the same structure as the first formwork panel on a side surface of the first formwork panel; and   placing a fourth formwork panel having the same structure as the first formwork panel on a side surface of the second formwork panel such that a heat insulating material of the third formwork panel and a heat insulating material of the fourth formwork panel face each other.
