In addition, the technical features involved in the different embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

Example 1

The invention provides a freezer terrace laying structure based on resistance stress deformation, as shown in fig. 1-2, comprising: the resistance structure 4 comprises a plurality of structure squares 41, one end of each structure square 41 is arranged on the wall body 1, the other end of each structure square 41 protrudes into the terrace 3, each structure square 41 comprises a plurality of resistance surfaces which form different angles with the wall body 1, the terrace 3 at least comprises a heat insulation layer 31, the resistance structure 4 is embedded into the heat insulation layer 31, the heat insulation layer 31 comprises heat insulation plates, and at least intervals for the heat insulation plates to be embedded into are reserved between every two adjacent resistance structures 4. The structural square 41 is fixed on the wall body 1 and integrated with the wall body 1. Make the area of contact increase between wall body 1 and the terrace 3, compare with current wall body 1 and the 3 plane contacts of terrace, still increased the pincers of wall body 1 between the terrace 3 and closed the structure, increased the bonding strength between wall body 1 and the terrace 3. Because the wall body 1 and the terrace 3 form a plurality of mutually contacted resisting surfaces due to the shape of the structural square 41, and the resisting surfaces have a plurality of different combination angles, even if a gap exists between the wall body 1 and the terrace 3, a gap channel penetrating into the refrigerator is difficult to appear. On the other hand, in the process that the service life of the whole structure is prolonged, when the wall body 1 and the terrace 3 are subjected to cold and heat change to generate stress deformation, the contact surface angles between the wall body and the terrace are more, deformation bodies at most joint surface parts are in conflict with each other when deformation occurs, and a gap channel penetrating through the inside of the refrigeration house is still difficult to occur. Meanwhile, due to the existence of the resisting surfaces with different angles, the deformation resisting capacity between the wall body 1 and the terrace 3 is enhanced, and the deformation is not easy to occur. Even if the deformation occurs, the slit channel penetrating into the interior of the refrigeration house can not be generated, and the condition that the performance of the refrigeration house is reduced due to stress deformation is greatly reduced.

The structural part 41 comprises a filling cavity, and a filling layer 44 is arranged in the filling cavity; the filling cavity is formed by buckling the structural square 41 and the wall body 1, and/or the filling cavity is arranged in the structural square 41.

When the cavity and the terrace 3 deform due to the change of cold and heat, the structure 41 can play a role in resisting the buffering and absorption.

On the basis of the above solution, the structure of the structural part 41 is not specifically limited, and as a further alternative embodiment, as shown in fig. 2, the structural part 41 further includes: the first screw 42 and the first nut 43, the first screw 42 sequentially penetrates through the structural component 41 and the filling layer 44, the first screw 42 penetrates into the wall body 1, the first nut 43 is arranged in the filling cavity, and the side wall of the structural component 41 is clamped between the first screw 42 and the first nut 43. The first nut 43 can improve the supporting strength of the structure side 41 to the first screw 42, and prevent the first screw 42 from breaking the side wall of the structure side 41. On the other hand, the first nut 43 is fixed to a side wall of the structure 41, and serves as an intermediate member for connecting the first screw 42 and the structure 41. As an alternative embodiment, the through hole of the structural side 41 for the first screw 42 to pass through is provided with a screw thread, and the first nut 43 only plays a role of clamping the side wall of the structural side 41, preventing the side wall of the structural side 41 from being deformed, and improving the strength of the side wall of the structural side 41.

Wherein the resistant structure 4 further comprises: and the outer cladding 45 is laid on the outer surface of the structural square 41, and the outer cladding 45 is clamped between the terrace 3 and the structural square 41. The outer cladding 45 can serve to modify the dimensions of the resistant structure 4. The shape of the integral resistance structure 4 is more regular by utilizing the outer cladding 45, the size deviation of the resistance structure 4 formed by the deviation of the arrangement position of the structure side 41 is corrected, and a foundation is laid for the subsequent laying work of the insulation board. The outer cladding 45 in this embodiment is constructed of a polyurethane material. As an alternative embodiment, the overwrap 45 is a plastic material.

In this embodiment, as shown in fig. 1, one end of the insulation board close to the wall 1 abuts against the wall 1 and/or the resistant structure 4, and distances from the surfaces of the insulation board abutting against the wall 1 and the resistant structure 4 to the wall 1 are different, so as to form a staggered laying structure. There is the concatenation gap between the heated board, and crisscross laying structure can eliminate the influence that the concatenation gap caused the heat preservation effect. The mosaic structure is naturally formed by the presence of the resistant structure 4 without additional work for measurement calculations.

As for the distribution manner of the resistant structure 4, there is no particular limitation, and as a further alternative embodiment based on the above embodiment, as shown in fig. 4, the structural side 41 is a bar shape. As another alternative, as shown in fig. 5, the structural members 41 are prism-shaped and uniformly distributed on the wall 1. As another alternative, as shown in fig. 6, the structural squares 41 are distributed in a staggered manner. As another alternative, as shown in fig. 7, the structural member 41 has an irregular prism shape and is obliquely disposed on the wall body 1. The embodiment of fig. 7 can further improve the bonding strength between the structural formula 41 and the floor 3, and plays an auxiliary supporting role for the whole floor 3, thereby preventing the floor 3 from collapsing or bulging due to stress change.

As shown in fig. 3, the insulation board is coated with a buffer material at least on a surface in contact with the wall 1 and/or the resistant structure 4 to form a protective layer. On the one hand, the protective layer can be filled in gaps between the heat-insulation board and the wall body 1 and/or between the heat-insulation board and the resistance structure 4, so that the overall heat-insulation effect of the terrace 3 is improved. On the other hand, the protective layer can play a role in improving the structural strength of the insulation board. In this embodiment, the protective layer is made of a polyurethane material and/or a plastic material.
