Problems solved by technology

[0004] However, if the caulking with tape is performed as described above, in order to prevent the foaming agent from leaking out, it is necessary to stick the tape so that there is no gap, so it takes a lot of labor and time.
In particular, it is sometimes necessary to perform caulking work at dozens of places on one board, which is laborious
Also, sometimes gaps still appear even with caulking

Embodiment Construction

[0013] Hereinafter, the best mode for carrying out the present invention will be described in detail with reference to the drawings.

[0014] figure 1 An embodiment of the refrigerated container according to the present invention is shown. The refrigerated container 10 which concerns on this embodiment has the box body 12 of rectangular parallelepiped shape, and the plate provided in the longitudinal direction end part of this box body 12 is a multilayer structure plate which is one embodiment of this invention.

[0015] Such as figure 2 As shown, the above-mentioned multilayer structure panel 14 has an outer panel 16 constituting the outer wall of the box body 12, an inner panel 17 constituting the inner wall of the box body 12, and an insulating material 18 as an intermediate material provided between these panels 16, 17. . The outer panel 16 is made of aluminum, and the inner panel 17 is made of resin. The heat insulating material 18 is formed by using, for example, a ...

Abstract

The objective of the invention is to prevent leakage of an intermediate material disposed between panels and reduce labor required for closing gaps. In a double-layer structure panel, an intermediate material in a fluid state or a state solidified from the fluid state is disposed between the pair of panels. The double-layer structure panel has a female screw member (30) fitted in a through hole (16a) formed in an outer panel (16) and also has a cap (40) fitted on the female screw member (30). The cap (40) has a closed-bottomed hollow cylindrical body part (41) for closing the screw hole of the female screw member (30) and fitted in an intimate contact manner to the outer peripheral surface of the female screw member (30). The cap (40) also has an intimate contact part (42) supported by the body part (41) and adapted so that at least a part of the intimate contact part can be in intimate contact with the outer panel (16).

Description

technical field [0001] The invention relates to a cover, a multi-layer structural panel and a refrigerated container. Background technique [0002] Conventionally, as disclosed in the following patent document 1, the refrigerated container provided with the panel of a heat insulating double wall structure is known. The body panel of this refrigerated container has an aluminum outer panel, a resin inner panel, and a foaming agent as a heat insulating material filled between these two panels. In addition, nuts that can fasten and fix the fan, frame, etc. are fixed on the outer plate. Most of the nuts are riveted nuts. That is, a through-hole is first formed in the outer plate, and then the nut is fixed by fitting the nut into the through-hole for caulking. Since the rivet nut is fixed in the through hole after forming the through hole on the outer plate in this way, when the filled foaming agent is in a fluid state before curing, the caulking is used to prevent the foaming ...
