  The decorative board peeling prevention structure according to the present embodiment is configured such that the decorative board in the ceiling portion of the heat insulating room assembled by orienting the decorative board to the indoor side by the heat insulating panel having the decorative board attached to the surface of the heat insulating material. The ceiling portion is configured by arranging a plurality of the heat insulation panels in a planar shape, and a beam body is arranged along the joint of the heat insulation panel above the ceiling portion. A bar-like body penetrating the ceiling portion at the intersection of the heat-insulating panel joints is suspended from the beam body, and a corner of the heat-insulating panel is placed on the lower end of the bar-like body. The present invention provides a structure for preventing a decorative plate from peeling off, characterized in that a seat plate for supporting the plate from below is provided.

  Here, the heat insulation room is not particularly limited as long as it is a room surrounded by a heat insulation panel. For example, in addition to a refrigeration room, a freezing room, a clean room, etc. It can be interpreted as a laboratory constructed with emphasis on sex.

  Moreover, the heat insulation panel used for construction of at least a ceiling part of a heat insulation room in this embodiment is provided with a decorative board. Specifically, a decorative board is attached to at least one of the front and back surfaces of a heat insulating material formed in a plate shape. The decorative sheet peeling prevention structure according to this embodiment is intended to prevent peeling of the decorative board arranged on the indoor side of the heat insulating panel in the ceiling.

  The material of the decorative board which comprises a heat insulation panel is not specifically limited, For example, it can be understood as a metal, resin, a woody material, paper, or these composite materials.

  In particular, metal decorative panels are widely used to increase the fire resistance of thermal insulation panels, and also contribute to improving the strength of thermal insulation rooms and improving the thermal efficiency (cooling efficiency) of rooms. There is concern about peeling from the ceiling due to fire.

  On the other hand, the decorative sheet peeling prevention structure according to the present embodiment functions extremely effectively for such a metallic decorative board.

  In addition, the peeling prevention structure of the decorative board which concerns on this embodiment does not necessarily prevent peeling of the decorative board from all the heat insulation panels which comprise a ceiling part.

  In other words, this structure may be applied in order to prevent a part of the heat insulating panels constituting the ceiling portion from being peeled off. As an example of such a mode, for example, securing a passage for a person engaged in fire fighting activities can be mentioned.

  The heat insulating material is not particularly limited as long as it is a material that can effectively block heat propagation, and for example, a resin foam can be used. As a suitable example of such a resin foam, Kanelite Foam made by Kaneka Co., Ltd., which has high flame retardancy conforming to the flammability standard of JIS A 9511 formed by foaming polystyrene resin with butane, Asahi Kasei Corporation The thermosetting resin panel made from a product can be mentioned.

  Moreover, in the decorative sheet peeling prevention structure according to the present embodiment, the ceiling portion is configured by arranging a plurality of heat insulating panels in a planar shape. These heat insulation panels may be connected to each other and arranged side by side in a planar shape.

  And the beam body is arrange | positioned along the joint which is the boundary of the heat insulation panel arrange | positioned planarly above this ceiling part, ie, the ceiling back side. This beam body does not necessarily have to be disposed on all joints.

  In the beam body, a rod-like body penetrating the ceiling portion is suspended downward at the intersection of the joints of the heat insulation panel. Although the raw material of a rod-shaped body is not specifically limited, The thing made from stainless steel with low heat conductivity can be employ | adopted suitably.

  Further, the joint of the joints may be a part where the joints cross in a cross shape when, for example, a rectangular heat insulation panel is used, or a part where the joints cross in a T-shape. There may be. In other words, the joint may be an L-shaped crossing part.

  However, these are cases where rectangular heat insulation panels are used, and this is not the case when heat insulation panels having other polygonal shapes in plan view are used. As a specific example, when a heat insulating panel having a regular triangle in plan view is used, a point where corners of the plurality of heat insulating panels are gathered in an asterisk shape can be interpreted as an intersection of joints.

  A seat plate parallel to the ceiling is placed at the lower end (inside of the room) of the bar that penetrates the ceiling, and the decorative panel is supported from below by placing the corners of the heat insulation panel. To do.

  By adopting such a configuration, even when a fire has occurred, it is possible to prevent the decorative panel placed on the indoor side of the heat insulating panel that constitutes the ceiling part from peeling off into the heat insulating room as much as possible. can do.

  Further, in the decorative plate peeling prevention structure according to the present embodiment, the beam body is a clip member provided with a spacer inserted between the webs of the two groove-type steel materials facing each other. Both steel materials may be sandwiched together while forming a gap.

  The groove type steel material is a steel material having a substantially U-shaped cross-sectional view, and examples thereof include a groove type steel, a lightweight groove type steel, a lip groove type steel, etc. Among them, a lip groove type steel can be preferably used. .

  The clip member is a member for integrally sandwiching two groove-type steel materials with the web sides facing each other in a state in which a gap is formed between the webs by separating them by a predetermined distance by a spacer.

  And the above-mentioned rod-shaped body is arranged so as to avoid contact with both steel materials in the gap, and its upper part is locked to a bridging member spanned between both steel materials. In other words, the gap is larger than the diameter of the rod-shaped body, so that the rod-shaped body can be disposed in the gap without contacting the webs of both channel steel materials.

  By setting it as such a structure, generation | occurrence | production of the heat bridge inside and outside a heat insulation room can be prevented as much as possible, and the heat insulation can be improved.

  In particular, when the indoor temperature of the heat insulating room is kept lower than the air temperature, it is necessary to eliminate as much as possible the heat bridge structure that promotes heat conduction inside and outside the room in order to avoid condensation. Therefore, the number of members penetrating the ceiling portion is small, the cross-sectional area and thermal conductivity of the member are made as small as possible, and the contact area between the member penetrating the ceiling portion and the member arranged outside the heat insulation chamber is made small. Is desirable.

  On the other hand, in the decorative plate peeling prevention structure according to the present embodiment, the member penetrating the ceiling portion is one rod-shaped body per intersection of joints, and since it is rod-shaped, the cross-sectional area is small, and it is formed by using stainless steel. Conductivity can be reduced as much as possible, and since the rod-shaped body is configured to be locked to the beam body by the bridging member while avoiding contact with the steel material, the contact area with the member disposed outside the heat insulation chamber is extremely small .

  With such a configuration, in the decorative plate peeling prevention structure according to this embodiment, it is possible to effectively prevent condensation.

  The corner of the heat insulating panel used for the ceiling may be cut off in part on the decorative plate in advance, and the exposed heat insulating material may be chamfered and placed on the seat plate.

  In other words, it is preferable to partially cut out the decorative plate in advance at the corners of the heat insulating panel arranged on the seat plate. However, it is not always necessary to cut out the decorative panels at all corners of the heat insulating panel. It is desirable to cut out the decorative plate at least at the corners placed on the seat plate or only at the corners placed on the seat plate.

  By having such a configuration, when constructing the ceiling portion, it is not necessary to cut the decorative plate made of metal or the like when penetrating the ceiling portion with a rod-shaped body, and the insulating material is not cut by a cutter or the like. Chamfering can be easily performed only by cutting to form the relief portion of the rod-shaped body.

  Further, the seat plate may be substantially circular in plan view, and a marker may be formed on the circumferential edge of the seat plate at least every ¼ arc.

  By providing such a configuration, the corners of the panel can be arranged in an orderly manner on the seat plate, and it is possible to prevent the heat insulation panel constituting the ceiling portion from shifting.
