Wall Structure Of Large-Sized Refrigerated Storage And Construction Method Thereof

Abstract

A method for constructing a wall structure, which comprises an interior wall board, an exterior wall board and a skeleton positioned between the interior wall board and the exterior wall board. The method for construction the wall comprises the following steps: A. building the wall skeleton; B. mounting a color steel plate on the outer surface of the skeleton to form an exterior wall board of the wall; C. painting the polyurethane spraying material on the exterior wall board layer by layer for multiple times, and reserving a pouring apace at a distance of 40 to 80 mm from the installation position of a interior wall board; and D. taking the color steel plate of the interior wall as a mould plate and pouring space at the color steel plate of the interior wall to form the interior wall board of the wall.

What is claimed is: 
     
         1 . A method of construction wall of a large-sized refrigerated storage, wherein the method comprises the steps of:
 A. building the wall skeleton, each skeleton of the wall of the refrigerated storage being connected reciprocally, so as to forming an overall framework;   B. mounting a color steel plate, a stainless steel plate, a aluminum plate or a sandwich panel on the outer surface of the skeleton to form an exterior wall board of the wall of the refrigerated storage by assembling the stainless steel plate, the aluminum plate or the sandwich panel;   C. painting the exterior wall board with a polyurethane spraying material layer by layer for multiple times, and reserving a pouring apace at a distance of 40 to 80 mm from the installation position of a interior wall board; and   D. mounting a color steel plate, a stainless steel plate or a sandwich panel of the interior wall board in order by taking a color steel plate, a stainless steel plate or a sandwich panel of the interior wall as a mould plate and pouring a polyurethane spraying material into the pouring space at the color steel plate, the stainless steel plate or the sandwich panel of the interior wall and then mounting another color steel plate, another stainless steel plate or another sandwich panel of the interior wall board after the solidification of the polyurethane spraying material and then pouring a polyurethane spraying material again to form a interior wall board of the wall of the refrigerated storage.   
     
     
         2 . The method of construction wall of a large-sized refrigerated storage according to  claim 1 , wherein said step A further comprises the steps of:
 building the skeleton with C-shaped steel columns and angle steels by providing a line of C-shaped steel columns situated at the exterior wall board or a high-temperature side, the distance between the adjacent steel columns being ranged from 2000 mm to 4000 mm; and providing a plurality of lateral fixed angle steels on the C-shaped steel columns being up, each broken cold-bridge component having one end thereof being soldered to the angle steel situated at the exterior wall board and the other end thereof being soldered to the angle steel situated at the interior wall board.   
     
     
         3 . The method of construction wall of a large-sized refrigerated storage according to  claim 2 , wherein the distance between the adjacent insulation rods of broken cold-bridge component positioned on the same level ranges from 500 mm to 1000 mm. 
     
     
         4 . The method of construction wall of a large-sized refrigerated storage according to  claim 1 , wherein the color steel plate, the stainless steel plate or the aluminum plate of the exterior wall board and the color steel plate, the stainless steel plate or the sandwich panel of the interior wall board are fixed to the angle steels of the skeleton by self-tapping screws or sealed type blind rivets in the steps of B and C. 
     
     
         5 . The method of construction wall of a large-sized refrigerated storage according to  claim 1 , wherein the spraying method of layer by layer for multiple times in the step C further comprises the steps of:
 taking a thickness of the polyurethane spraying material being 10 nun to 15 mm of the color steel plate, the stainless steel plate or the sandwich panel of the interior wall as a mould plate at the first time of spraying;   forming a thickness of the polyurethane spraying material being 15 mm to 25 mm at the second time of spraying;   forming a thickness of the polyurethane spraying material being 25 mm to 35 mm at the third time of spraying, and taking the thickness as the model for each spraying after that until producing a distance of 40 mm to 80 mm from the interior wall board; and   each interval between two sprayings being not less than 5 minutes.
