Detailed Description

The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are presented herein only to illustrate and explain the present invention, and not to limit the present invention.

As shown in fig. 1 to 4, the present invention provides a preferable structure of a cold storage plate convenient for welding and fixing.

The refrigeration house plate of this embodiment is the plate of rectangle, and its refrigeration house plate main part includes at least steel sheet 1, foaming layer 2 and the steel sheet 1 that from top to bottom overlaps in proper order and establishes. The foaming layer 2 is a heat-insulating layer formed by foaming polyurethane. The steel plate is a stainless steel plate.

As shown in fig. 1, preferably, the cold storage plate main body comprises a steel plate 1, a phenolic plate 3, a foaming layer 2 and the steel plate 1 which are sequentially stacked from top to bottom. Wherein the phenolic plate 3 can be connected with the steel plate 1 through an adhesive.

The forming process of the cold storage plate main body is realized by the person skilled in the art, and is not described too much here.

Currently, the thickness of the steel plate 1 of the existing refrigeration house plate is generally more than 0.4mm, and most of the thickness is less than 1 mm. And then the steel plate 1 between the cold storage plates is fully welded (namely, all the contact parts of 2 workpieces to be welded are welded), and the steel plate 1 is thin, the full welding workload is large, the operation is easy to miss, and the problem that the steel plate 1 is burnt through is very easy to occur. The heat preservation effect is influenced to a certain extent by the damage of the refrigeration house plate.

For this reason, the applicant innovatively makes the following improvements to the steel sheet 1:

as shown in fig. 2, an integrated bent portion 11 is provided on an outer edge of the steel plate 1. This portion of bending 11 is used for local increase welding thickness to satisfy the welding demand, reduce the problem of burning through. In order to close all seams, the length of the bend 11 is adapted to the length of the outer edge of the steel plate 1.

Specifically, the bent portions 11 are respectively disposed on two opposite outer edges of the steel plate 1. That is, provided on both long sides of the steel plate 1 to be welded to the adjacent cold storage plates. The other two outer edges of the steel plate 1 are preferably not provided with the bent parts 11, namely two short edges of the steel plate 1, so as to be convenient for erecting the refrigeration house plate and installing the refrigeration house plate with the refrigeration house top plate

As shown in fig. 3, the bent portion 11 includes a first folded edge 111 and a second folded edge 112, and the first folded edge 111 is used for joining the steel plate 1 and the second folded edge 112.

Specifically, the first folding edge 111 is bent inward, that is, the first folding edge 111 is bent toward the side wall of the refrigeration house plate main body. The included angle between the first folded edge 111 and the side wall of the refrigeration house plate main body is smaller than 90 degrees.

As shown in fig. 3, the second folded edge 112 is folded outward, and the first folded edge 111 is interposed between the second folded edge 112 and the side wall of the refrigeration house panel main body. Meanwhile, the second folded edge 112 is perpendicular to the steel plate 1, or the second folded edge 112 is parallel to the side wall of the refrigeration house plate main body. The second folded edge 112 is welded when being used for assembling the refrigeration house plate so as to close the joint.

A freezer board theory of operation convenient to welded fastening be:

the steel sheet still adds the portion of bending, and the refrigeration house plate is compound, and the second of two refrigeration house plates is rolled over the limit and can coincide each other, through welded connection between the second is rolled over the limit to seal the seam. During welding, the two second folded edges can be welded after being overlapped, and the outer edges of the second folded edges are welding positions.

Through the design, the thickness of the steel plate is not increased, meanwhile, the width of the second folded edge is utilized to increase the thickness of welding, the welding quality is improved, and the full-length welding is facilitated. The second hem in the portion of bending is perpendicular to the surface of steel sheet, and through this mode, the refrigeration house plate is compound, and the surface of adjacent second hem can fully contact, guarantees welding quality, and is difficult to burn through.

On the other hand, the uneven structure of the bent portion 11 serves as a rib to reinforce the bending resistance of the edge of the steel plate 1.

Preferably, the width of the second flange 112 is not less than 2 mm. The thickness of the welding part is large enough to meet the welding requirement.

As shown in fig. 3, the outer edge of the second flange 112 is preferably flush with the surface of the steel plate 1. After the refrigeration house plate is welded into the composite wallboard in a combined mode, the surface is smooth, and workers and goods cannot be scratched.

The width of the first folded edge 111 is smaller than the thickness of the refrigeration house plate main body. Specifically, the width of the first folded edge 111 is smaller than that of the foamed layer 2 or the phenolic plate 3. The material of the steel plate 1 is reduced, and the design is reasonable and compact.

As shown in fig. 3, since the bent portion 11 has a certain thickness, in order to improve the thermal insulation performance, a stepped groove 31 is formed in the sidewall of the phenolic plate 3, and the stepped groove 31 is used for accommodating the bent portion 11. The refrigeration house plate main body is filled with the heat insulation material at the position of the bending part 11, and the internal clearance between the refrigeration house plates is reduced as much as possible. And the foaming layer 2 can fill the gap between the steel plate 1 and the phenolic aldehyde plate 3 in the foaming process.

The utility model also provides a refrigeration house, which comprises a plurality of refrigeration house plates convenient to weld and fix; the bending parts between the adjacent cold storage plates are arranged oppositely, the second flanging between the adjacent cold storage plates is in close contact with the second flanging, and the adjacent second flanging is connected through welding.

Other structures of the refrigeration house plate and the refrigeration house convenient to weld and fix in the embodiment are referred to in the prior art.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in any way, so that any modification, equivalent change and modification made by the technical spirit of the present invention to the above embodiments do not depart from the technical solution of the present invention, and still fall within the scope of the technical solution of the present invention.
