Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a thermal insulation panel for a floor of a building in which the influence of outside air temperature is reduced, such as a constant temperature room or a low temperature warehouse, and is damaged from a reinforcing member of the thermal insulation panel for a floor embedded in a position where heavy equipment is installed. The present invention relates to a thermal insulation panel for floors with improved thermal insulation.
[0002]
[Prior art]
For heat insulation and cold insulation in refrigeration, refrigerators, etc., individually adopt foamed resin heat insulation materials such as urethane, and form heat insulation walls, heat insulation floors, heat insulation ceilings, etc. by combining heat insulation panels that are sandwiched by hard shapes. This has been practiced more widely than before and is in practical use.
[0003]
For example, in the utility model application publication No. 16032 in 1971, a foam heat insulating material is provided between the groove-shaped edges in a metal thin plate or a synthetic resin plate formed with a groove-shaped edge in the peripheral portion of the outer plate. It is shown that it is filled to form a heat insulating wall and combined to form a heat insulating wall such as an assembled cold storage.
[0004]
[Problems to be solved by the invention]
In recent years, a machine or the like is installed in a refrigeration / refrigerator constituted by such a heat insulating panel, and operations such as product manufacture are increasing in the refrigeration / refrigerator. However, since the heat insulation panel as described above is composed of a foamed resin heat insulation material such as urethane and a hard shape material such as a metal thin plate as described above, a large machine / When installing and operating equipment, it is highly likely that the load of such equipment will not be able to withstand the load such as the large equipment directly applied to the floor and is damaged by the load of the large equipment. The deterioration of heat insulation was obvious, and reinforcement measures were required.
[0005]
In order to solve such a problem in the prior art, the present inventors have adopted a reinforcing structure as shown in FIG. That is, when installing mechanical equipment, the reinforcing steel plates 2 and 2 and the iron pipes 3 and 3 are joined together in the heat-insulating panel that needs to be reinforced in advance. Insulating panel by inserting a reinforcing member combined with a heat insulating heat insulating plate 4 to prevent condensation and the like between the panel surface plates 1 and 1 and injecting and filling a foamable resin heat insulating material 5 such as urethane. Reinforcement against heat load and heat insulation / cold insulation are ensured.
[0006]
However, the heat insulating material 4 for heat insulation for ensuring heat insulation and heat retention is expensive because it requires a special action, and the iron pipe 3 as a reinforcing member is used in the work site including its welding. It has been known that it is a problem to be further solved that it must be low, and it is not necessarily preferable from these points.
[0007]
[Means for Solving the Problems]
The present invention has been made by repeatedly studying to solve the above-described problems, and is as follows.
[0008]
(1) In a floor insulation panel in which a heat insulating material is foam-filled in the internal space between the front surface plate and the back surface plate, the weight to be placed between the reinforcing steel plates arranged in the thickness direction. a reinforcing member having a predetermined dimension corresponding to the spacing of the front and back surface plates through a synthetic resin material having a strength for the weight of the equipment, so as to reinforce steel plate are both in contact with the surface plate, the both surfaces plate Floor insulation panel characterized by being embedded in between.
[0009]
The floor insulating material according to claim 1, wherein a heat insulating material is also foam-filled between a plurality of synthetic resin materials extending in the thickness direction and reinforcing steel plates provided on the upper and lower sides of the synthetic resin material. Thermal insulation panel.
[0011]
Weight of heavy equipment on which the space between reinforcing steel plates facing in the thickness direction should be placed in a floor insulation panel in which a heat insulating material is foam-filled in the internal space between the front surface plate and the back surface plate By embedding a reinforcing member having a predetermined size through a synthetic resin material having a strength that can withstand the above, between the two surface plates, a reinforcing structure in which the two surface plates are integrated by the reinforcing iron plate and the synthetic resin material Provided is a floor insulation panel that is properly reinforced, effectively resists the weight of heavy equipment, and prevents thermal bridges.
[0012]
Synthetic resin material provided in the thickness direction by foaming and filling a heat insulating material between the synthetic resin material provided in the thickness direction and the reinforcing iron plate provided above and below the synthetic resin material. In addition, the reinforcing iron plate is effectively integrated with the foam filling layer between the front and back surface plates so as to obtain a stable supporting action for a device having a considerable weight.
[0013]
The support part constituted by arranging a plurality of synthetic resin materials by freezing the reinforcing steel plates facing each other on the top and bottom surface plates of the synthetic resin material arranged in the thickness direction is frozen, To provide a stable heat insulation panel for setting heavy equipment in a refrigerator.
[0014]
That is, by doing the above, heat insulation performance and reinforcement of the heat insulation panel can be sufficiently secured, and workability in field work can be effectively improved, and stable support is possible even under conditions where heavy objects are mounted. A state and a precise heat insulation characteristic can be secured. Here, the synthetic resin material may be an extruded material of synthetic resin, or may be a cut material or a cut material from a plate material or the like.

【Example】
FIG. 1 is a partial cross-sectional view showing an embodiment of the present invention as described above, in which the upper and lower reinforcing iron plates 2 and 2 and the synthetic resin extrudates 6 and 6 are joined together with an adhesive. In this case, a reinforcing member is inserted between the upper and lower panel surface plates 1 and 1 such as an iron thin plate or an aluminum thin plate material, and a foamed resin heat insulating material 5 such as urethane is injected and foamed and filled. Thus, both the reinforcing property against the load as the heat insulating panel and the heat retaining / cold retaining properties are ensured. As the synthetic resin material, for example, polyvinyl chloride (PVC), ABS resin, polystyrene, polypropylene (PP), polycarbonate, acrylic, polyacetal and the like can be used.
[0016]
That is, according to the configuration of the present invention as described above, the heat insulation performance is sufficiently improved by changing the iron pipe that has been a thermal bridge in the prior art as the reinforcing member for the refrigerator / refrigerator to the synthetic resin material 6, It is not necessary to use expensive heat insulating material for cushioning insulation to maintain heat insulation performance, and the above synthetic resin extruded material can be easily and accurately cut with an adhesive such as cutting at the work site and joining with an iron plate. Therefore, it is possible to secure both advantages such as a great reduction in work time.
