[0001] The utility model relates to container technology field more specifically, it relates to a reinforced roof structure. BACKGROUND
[0002] The conventional refrigeration box is spliced sandwich foaming structure, and the foaming between parts is called main foaming operation, and there is a part of cavity in the top corner part during final assembly, which is called secondary foaming. The secondary foaming is injected into the bubble body from the injection port, and the top corner seal and the inner top reinforcing rib are easily impacted to cause bubble leakage, and the strength is also affected. In addition, the conventional roof structure only needs to carry out roof experiment, so the roof strength is relatively weak. In special cases, the refrigeration box for grain needs to lift the door end by 90 degrees, and the other end becomes the bottom surface ground, so the strength requirement is higher, and the existing structure can be deformed and twisted.

[0006] Further, the roof corner is composed of a horizontal and vertical hollow beam, the top corner seal is connected to the inner corner of the roof corner, and the top side beam is connected to the outer corner of the roof corner.
[0007] Further, the bottom surface of the horizontal hollow beam of the roof corner is provided with an inner roof, the inner roof is provided with an inner top reinforcing rib, the inner top reinforcing rib extends out of the main foaming area and the end portion of the inner top reinforcing rib under the secondary foaming area is provided with the right-angle notch.
[0008] Further, the connecting reinforcing rib is inwardly arranged and connected to the back of the right-angle notch and the corner seal reinforcing rib at both ends.
[0009] Furthermore, the top side beam is a right-angle plate connector, one end of the top side beam has a recessed section, the recessed section is provided with the injection port, and the other end of the top side beam is provided with an inward hook section.

[0015] Example:
[0016] The following is in conjunction with the appendix Figures 1-2 The present invention will be described in further detail below.
[0017] A reinforced roof structure is proposed, which adds two reinforcing ribs to the original roof structure and improves the inner roof reinforcing ribs to complement the structural improvements.
[0018] Basic roof structure such as Figure 1 As shown, the structure includes a top plate corner, with a corner seal at the inner corner, which is a right-angle plate connector. A top side beam is located at the outer corner of the top plate corner. The top side beam is also a right-angle plate connector. One end of the top side beam connects to the vertical section of the top plate corner, and this end has a recessed section. The other end of the top side beam has a hook section that curves inward, and its outer surface connects to the horizontal section of the top plate corner. An injection port connecting to the interior of the top plate corner is located in the recessed section of the top side beam. Both the vertical and horizontal sections of the top plate corner have main foaming areas, and a secondary foaming area is located at the corner of the top plate corner. Within the main foaming area of the horizontal section, an inner top reinforcing rib is located on the inner top plate, with the end of the inner top reinforcing rib extending out of the main foaming area and entering the secondary foaming area.
[0019] likeFigure 2 As shown, the reinforcing rib of L-shaped section is arranged on the top plate structure, one end of the reinforcing rib is arranged outward and is called corner reinforcing rib, and the other end of the reinforcing rib is arranged inward and is called connecting reinforcing rib. The part of the inner top reinforcing rib extending out of the main foaming area and into the bottom of the secondary foaming area is provided with a right-angle notch. The two ends of the corner reinforcing rib are respectively arranged on the concave section and the hook section of the top side beam, and the position where the corner reinforcing rib is connected with the concave section is below the injection port, so that the foaming material injected can be blocked in the closed cavity structure formed by the corner of the corner reinforcing rib and the top side beam, the impact of the foaming material on the inner top reinforcing rib and the inner end of the corner of the top plate is reduced, and the foaming material leakage is prevented. One end of the connecting reinforcing rib is connected with the corner reinforcing rib, and the other end is connected to the right-angle notch of the inner top reinforcing rib, and the corner reinforcing rib is reinforced by the support of the inner top reinforcing rib, the main foaming area and the corner of the top plate, the strength of the overall structure is improved, and the product quality is improved.
