Description

[Detailed description of the invention] Industrial applications TECHNICAL FIELD This invention relates to a freezer.

2. Description of the Related Art In general, the roof and walls of a freezer include an outer roof and an inner roof, and an outer wall and an inner wall that are connected and supported by supporting members, and a heat insulating material is provided between the outer roof and the inner roof and between the outer wall and the inner wall. It is often constructed by filling.

Problems to be Solved by the Invention However, since the interior side of a freezer is always extremely low in temperature, it is difficult to protect the insulation material and to connect and support the roof and walls between the outer roof and the inner roof, and between the outer wall and the inner wall. Due to heat conduction, the difference in temperature between the outdoor and indoor sides causes condensation and freezing, which has various negative effects on the freezer itself. For example, ice formation in the insulation material gradually causes the freezer to lose its insulation effectiveness and can also cause cracks to form at the corners of the building structure and at the joints of the exterior wall supports. This phenomenon increases the indoor temperature and becomes more noticeable as the size of the building increases.

This invention was proposed to solve these problems, and is a freezer that is completely free of dew condensation or ice formation due to the temperature difference between outdoors and indoors, and that can maintain a high insulation effect semi-permanently. The purpose is to provide

Means for Solving the Problems This invention provides the roof and walls of a freezer with an outer roof and an inner roof.
The outer and inner walls are connected by metal pipes,
Insulating material is filled between the outer roof and the inner roof, between the outer wall and the inner wall, and in the metal pipe, and heat transfer prevention plates are interposed at the joints between the metal pipe and the outer roof, the inner roof, the outer wall, and the inner wall. By configuring the system as follows, the above object is achieved.

Example The present invention will be explained below with reference to an illustrated embodiment.

The wall 2 of the freezer 1 has an inner wall 2a and an outer wall 2 with a heat insulating member 3 interposed therebetween.
It is composed of multiple layers with b. Further, the roof 4 of the freezer 1 has a plurality of layers including an inner roof 4a and an outer roof 4b with a heat insulating member 6 interposed therebetween.

The inner wall 2a of the wall 2 is a reinforced concrete ring frame. The outer wall 2b is constructed by pasting a square corrugated iron plate 15 on a lightweight steel frame base 14, and the heat insulating member 5 is made of glass wool with a thickness of about 50 cm. The roof 4 is a flat roof. The inner roof 4a of the roof 4 is a reinforced concrete ring slab. The outer roof 4b is constructed by pasting a plurality of ALC plates 9 having a thickness of about 10 crn on the heat insulating member 3, and pasting a waterproof sheet 11 thereon.

A metal pipe 8 such as a steel pipe containing heat insulating material that supports the outer wall 2b of the wall 2 is fixed with a locking bolt 7 with heat transfer prevention plywood 5 made of wood, hard resin, etc. sandwiched between the inside and outside.

A metal pipe 8 such as a steel pipe that supports the outer roof 4b of the roof 4 has a heat transfer prevention plywood 5 sandwiched therein and is fixed with a bolt 7. Also, the outside is covered with ALC plate 9 and the receiving part 1
Fixed by 0.

In this configuration, when the temperature inside the freezer 1 reaches an extremely low temperature, the heat transfer preventing plywood 5 prevents heat transfer, and the heat insulating material inside the metal pipe a prevents convection of air within the pipe. Further, the outer roof 4b of the roof 4 prevents the metal pipe 8 from coming into direct contact with the outside air.

Effects of the Invention This invention consists of the above-mentioned structure, and a heat transfer prevention plate interposed at the joint between the metal pipe and the outer roof, inner roof, outer wall, and inner wall is used to prevent heat transfer between the indoor side and the outdoor side. The structure is designed to minimize heat conduction and prevent convection of cold air with the insulating material inside the metal pipes, so even if the indoor temperature reaches extremely low temperatures, condensation of water and ice due to temperature differences can be prevented. In addition, the insulation effect of the freezer will not be permanently lost, and the structure will not suffer any similar problems.
