Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to a heat insulating material fixed to an upper surface of a cargo refrigerating barge and an aluminum protective plate provided below the heat insulating material.

[0002]

[Prior Art]

 Conventionally, as shown in FIG. 2, this type of device has a stiffening member 23 having a long depth and a stiffening member 23 having a short depth, which are arranged at a predetermined interval on the back surface of the deck 2 on the upper surface of the cargo refrigerating barge 21. A heat insulating material made of glass wool or molded polyurethane cut into a predetermined size is inserted between the materials 29, and a wooden plywood 25 is sandwiched between the lower surface of the molded heat insulating material 24 and a wooden joist 28. The stud bolts 26 welded vertically downward to the shallow stiffeners 29 are inserted, and the nuts 27 are tightened and fixed, and then the wooden plywood 25 is nailed to the lower surface of the wooden joist 28, and then the abdominal plate. It is known that the heat insulating material is applied by laminating the molded heat insulating material 24 and the wooden plywood 25 to a thickness that covers the deep stiffening material 23.

[0003]

[Problems to be solved by the device]

 As described in the prior art, when laminating the molded heat insulating material and the wooden plywood and applying the heat insulating material, the thickness covered with the heat insulating material is adjusted to the size of the stiffening material with a deep abdominal plate part. Therefore, the thickness of the heat insulating material covering the stiffening material with a shallow depth of the abdominal plate becomes thicker than necessary, increasing the weight of the hull, and the installer must work in an upward posture for a long time. The work efficiency is poor, and further, since the molded heat insulating material is cut by hand, an error occurs and a gap is formed at the joint portion of the heat insulating material, which lowers the heat insulating effect.

Further, there is a problem in that a pallet, a forklift, etc. are brought into contact with the heat insulating material and damaged during cargo handling, or the fire easily spreads during a fire.

The present invention has been made in view of the above problems of the conventional technique, and the purpose thereof is to easily adjust the necessary thickness of the heat insulating material, and The purpose of the present invention is to provide a heat insulating material protection plate for a cargo refrigeration barge that can shorten the work time in a facing posture and has a high heat insulating effect, and prevent damage and spread of fire.

[0006]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention provides a glass wool or rock wool heat insulating material with a predetermined size between the stiffeners arranged under the steel deck on the upper surface of the cargo refrigerating barge, and with the belly plate. Molded heat-insulating material that is cut and fitted to the required thickness according to the shallow stiffener, and sprayed on the surface of the molded heat-insulating material. A heat insulating structure is formed from a spray heat insulating material formed by spraying only this amount and a glass mesh spread and fixed on the surface of the spray heat insulating material, and the spray heat insulating material and the glass mesh are laminated in several layers. Then, each of the stiffeners is provided with a mounting bracket fixed to each of the stiffeners, a protection plate made of aluminum in which a wooden joist is bolted to the back surface of the stiffener, and a pillar bolt standing upright on the upper surface of the joist. A protective structure is formed, and the upper end of the strut bolt is attached to the mounting bracket. And fastening is made by hanging to maintain horizontally the protective plate to spray heat shield downwards.

[0007]

[Action]

 A molded heat insulating material fitted between the stiffeners facilitates removal of the heat insulating material during maintenance.

The sprayed heat insulating material by spraying makes it easy to adjust the thickness of the heat insulating material, and also shortens the working time of the upward posture of the builder.

The glass mesh spread on the surface of the sprayed heat insulating material prevents the heat insulating material from cracking.

The protection plate suspended below the spray heat insulating material prevents direct contact of the spray heat insulating material with a pallet, forklift, etc., and also prevents ignition and spread of heat to the heat insulating material.

[0011]

EXAMPLE An example will be described with reference to the drawings. As shown in FIG. 1, a deep stiffener of a belly plate portion, which is arranged at a predetermined interval on the back surface of the deck 2 on the upper surface inside the cargo refrigerating barge 1. Molded heat insulating material 4 which is made by cutting glass wool or rock wool between the 3 and the shallow stiffening material 7 of the abdominal plate to a required thickness in accordance with the short stiffening material 7 with a predetermined size. Fit in.

Next, by spraying molded polyurethane on the surface of the molded heat insulating material 4 by a necessary thickness corresponding to the deep stiffener 3 in the abdominal plate portion, a sprayed heat insulating material 5 is formed, and sprayed heat insulating material 5 is formed. The glass mesh 6 is spread and fixed on the surface of the material 5. Further, the spray heat insulating material 5 and the glass mesh 6 are laminated in several layers.

A mounting bracket 8 is fixed to each of the stiffeners 3 and 7, and a wooden joist 10 is bolted to the back surface of a protective plate 9 made of aluminum, and a pillar bolt 11 is erected on the upper surface of the wooden joist 10. Then, the upper ends of the pillar bolts 11 are fastened to the fittings 8, and the protection plate 9 is suspended below the spray heat insulating material 5 while being kept horizontal.

[0014]

[Effect of the device]

 Since the present invention is configured as described above, it has the following effects. Spraying the heat insulating material by spraying can easily adjust the thickness covered with the heat insulating material according to the deep stiffening material and the shallow stiffening material of the abdominal plate part, and the heat insulating material covering the shallow stiffening material of the abdominal plate part can be easily adjusted. The material does not become thicker than necessary, reducing the weight of the hull, shortening the working time in the upward posture of the builder, improving work efficiency, and further improving the joint part of the molded heat insulating material. It can fill the gap and improve the heat insulation effect.

Since the protective plate is hung below the spraying heat insulating material, the pallet and the forklift, etc. do not directly contact the heat insulating material during loading and unloading, and the heat insulating material is prevented from being damaged. Prevents fire from spreading to the heat insulating material and minimizes fire.
