Description

Detailed Description of the Invention "Industrial Application Field" This invention relates to the structure of the ceiling of each room of an offshore warehouse that is moored floating on the ocean, and particularly relates to the structure of the ceiling of each room of an offshore warehouse that is moored while floating on the ocean. The present invention relates to a ceiling structure in an offshore warehouse suitable for use as a low-temperature warehouse.

``Conventional technology'' Recently, with the liberalization of food imports, imports of fresh foods such as fruits, meat, and marine products have increased, and as a result, demand for large-scale refrigerated or frozen warehouses has increased.・
is made of. For this reason, refrigerated warehouses or refrigerated warehouses that will be constructed in the future tend to become larger year by year, and it is thought that in the future, warehouses with a capacity of about 10,000 to 50,000 tons will become commonplace.

However, recently, there is almost no vacant land near the quays where ships can load and unload cargo, and where new large-scale warehouses can be built. In addition to this, rising land prices have made it difficult to construct new warehouses in good locations due to the cost.

Furthermore, in the case of warehouses equipped with large-scale cooling equipment, such as refrigerated warehouses and frozen warehouses, the noise generated from the cooling equipment is large, which may cause noise pollution in the vicinity.

On the other hand, conventionally, when unloading a cargo of perishable foods such as citrus fruits, the cargo is first transferred to pallets in the hold, and then the entire pallet is unloaded using a shore crane. Leave it on the quay. Therefore, when storing a shipment of such perishable foods in a warehouse, the pallets are unloaded onto the quay and loaded onto several trucks using a forklift, and then the cargo is transported to a refrigerated warehouse by those trucks. It is necessary to repeat this operation several times, which is very time-consuming, and if the cargo is perishable, there is also the problem that the quality will deteriorate unless it is quickly transported to a refrigerated warehouse after landing.

Recently, attempts have been made to construct new warehouses offshore, where land is required (and where there is no risk of noise pollution to nearby areas), thereby speeding up the process from loading and unloading cargo to storing it inside the warehouse. is being explored.

``Problem to be solved by the invention'' By the way, when building a warehouse like the one above on the ocean, it is considered most desirable to float the warehouse like a ship (purge) and moor it to a quay. .

However, in offshore warehouses floating on the ocean, external forces such as waves, wind, and currents can damage columns, beams, etc.
There is a problem in that the outer walls etc. are distorted and twisted. In particular, when such offshore warehouses are used as low-temperature warehouses such as refrigerated warehouses and frozen warehouses, it is necessary to provide insulation performance to the ceilings, walls, floors, etc. inside the offshore warehouses.
For example, even if the inside of a cold storage warehouse on land is made airtight by directly attaching insulation materials to the inside of the pillars, beams, and outer walls, distortion will occur in the pillars, beams, outer walls, etc. of the offshore warehouse as described above. If twisting occurs, there is a risk that the joints of each insulation material may become misaligned, causing cold air to escape from the joints.In this case, the insulation performance within the offshore warehouse may deteriorate, causing the low-temperature warehouse to deteriorate. There was also the possibility that a problem would arise in which sufficient functionality could not be obtained.

This invention was made in view of the above-mentioned circumstances, and allows ceilings in offshore warehouses to maintain internal airtightness and maintain excellent heat insulation performance even when pillars, beams, outer walls, etc. are distorted or twisted. The purpose is to provide a structure for

"Means for Solving the Problem" The ceiling structure of an offshore warehouse of the present invention is a structure of the ceiling of each room in an offshore warehouse moored while floating on the ocean, and includes a plurality of rectangular heat insulation panels. are connected to each other, and at least some of the connecting portions of the respective insulation panels are connected via an elastic material, and both ends thereof are connected to the upper part of the wall of each room using elastic material. A plurality of the heat insulating panels are connected to each other through materials, and a plurality of the heat insulating panels are vertically movable and rotatable via a plurality of spring hangers attached to the steel beams above them. It is suspended from steel beams.

"Operation" In the structure of the ceiling in an offshore warehouse of the present invention, a plurality of rectangular heat insulating panels are connected together and At least some of the connecting portions of each of the heat insulation panels are connected via an elastic material, and both ends thereof are connected to the upper part of the wall of each room via the elastic material, and By suspending a plurality of the heat insulating panels from the steel beam above the heat insulating panels in a vertically movable and rotatable state via a plurality of spring hangers attached to the steel beam above the heat insulating panels, Even if the pillars, beams, outer walls, etc. of the offshore warehouse are distorted or twisted due to external environmental forces such as waves, wind, and tidal currents, the ceilings of each room in the offshore warehouse will always be stable and will not bend due to W4M. In addition, this prevents cold air from escaping due to misalignment of the joints between the insulation panels that make up the ceiling and the joints between the ceiling and the walls. The airtightness inside each room in the warehouse is always maintained in a good condition, and excellent insulation performance is always maintained. Therefore, if each room in the offshore warehouse is configured using the ceiling structure of this offshore warehouse, even if the offshore warehouse is used as a low-temperature warehouse such as a cold storage or frozen warehouse, This means that sufficient functionality can be obtained.

In addition, the cover 5 has a flexible cover 49 made of synthetic rubber or the like.
0 (Some products can be used at extremely low temperatures of -70'C)
The structure is covered with Note that the expander 48 is made of a closed-cell foam plastic having heat insulating properties, such as urethane foam.

For example, an expander 48 having a thickness of 20 to 25 mm is interposed in a compressed state between the ends of the heat insulating panels 23 located at both ends of the ceiling and the upper side of the wall panel 47, so that the ceiling Even if the distance between the ceiling and wall panel 47 changes somewhat due to distortion or twisting of the steel beams 21 etc. that support the wall panel 47, the joints between them are always kept closed without any gaps for insulation. It maintains its sexuality.

In addition, in such a ceiling, both ends may be joined to the upper side of the wall panel 47 as described above, but as shown in FIG.

The insulation panel 2 is inserted in a compressed state of about 0y, x.
The lower end of the heat insulating member 51 is also connected to the end of the heat insulating member 51 with a compressed gasket 45 interposed therein, and the upper and lower parts of the joint are covered with a flexible cover 50. It is connected to the upper end of the panel 47, and both left and right sides of the joint are covered with flexible covers 50.

Next, the walls of each room in this offshore warehouse 1 will be explained with reference to FIGS. 4 and 5.

As shown in FIG. 4, the walls of each room in the offshore warehouse 1 are constructed by suspending rectangular wall panels 47 from a plurality of hanging members 46 attached at predetermined intervals to the lower part of the steel beams 21. It is. The wall panel 47 is a panel with a heat insulating structure similar to the heat insulating panel 23 that makes up the ceiling, but unlike the ceiling where multiple pieces are connected, the wall panel 47 can make up the entire wall with one piece. A frame 52 is attached to the outer periphery of the frame 7 in order to have a large area and have enough strength to be suspended by the hanging member 46. A mounting bracket 53 for attaching the wall panel 47 to the lower end of the hanging member 46 is attached to the frame 52 located at the upper end of the wall panel 47.

As shown in FIG. 5, the above-mentioned hanging member 46 is similar to the above-mentioned hanging member 22 for suspending the ceiling, but the above-mentioned mounting bracket 53 is attached to the lower end portion of this hanging member 46. This mounting bracket 53 is attached to the frame 52 at the upper end of the wall panel 47 from both sides and is fixed with a bolt 54, and its upper part is attached to the spring hanger 31 of the hanging member 46. It is attached to the lower end of the shaft 35 of.

In each room configured using such wall panels 47, four wall panels 47 per room are each attached to a steel column 5 in order to configure the four walls of each room.
5 and one wall panel 47 that is suspended from the steel beam 21 at a predetermined distance and adjacent to each other.
and the side surface of the other wall panel 47 are joined in close contact from the upper end to the lower end with an expander 56 interposed therebetween. Note that the expanders 56 are similar to the expanders 48 described above, and are made of a closed-cell foamed plastic having heat insulating properties, such as urethane foam. By being interposed in a compressed state between the end of the matching wall panel 47 and the side surface of the wall panel 47, the steel beams 21, etc. supporting each wall, f channel 47, 47, etc. Even if the spacing between the wall panels 47, 47 changes somewhat due to distortion and twisting, the joints between them are always kept closed to maintain insulation.

Next, the floor structure of each room in this offshore warehouse 1 will be explained with reference to FIGS. 6 to 8.

As shown in FIG. 6, the floor of each room in this offshore warehouse 1 is constructed by placing a rubber plate 57 on top of the steel beam 21, and placing a heat insulating material made of polystyrene foam or the like on top of the rubber plate 57.
8 is attached, and lightweight concrete is poured on top of this heat insulating material 58 to form a floor plate 59. The above-mentioned lightweight concrete refers to aerated concrete mixed with an admixture such as an AE agent, or concrete using lightweight aggregate as an aggregate, and is strengthened by mixing glass fiber etc. as necessary. It is something that

The end of such a floor needs to be in close contact with the lower end of the wall panel 47, which is placed at a predetermined distance from the steel column 55, without any gaps.
The lower end of the wall panel 47 is joined to both ends of the upper surface of a heat insulating material 58 attached over the entire steel beam 21 via a double span 60, and the wall panel 47
An end portion of the floor plate 59 made of lightweight concrete is in close contact with the lower side surface of the floor plate 59 . Note that the expander 60 is similar to the expander 48 and 56 described above, and is made of a closed foam plastic having heat insulating properties, such as foamed urethane. The insulation material 58 is interposed between the upper surface of the insulation material 58 and the lower end of the wall panel 47 in a compressed state.
Even if the distance between the heat insulating material 58 and the wall panel 47 changes somewhat due to distortion or twist of the steel beam 21 supporting the wall panel 47 or the steel beam 21 supporting the wall panel 47,
These joints are always kept closed to maintain insulation.

Further, as an example of another floor, there is one as shown in FIG.

As shown in FIG. 7, this floor is constructed by attaching a heat insulating material 58 made of polystyrene foam or the like on the steel beam 21, and placing fiber reinforced plastic (FRP) on top of this insulating material 58.
), which is constructed by attaching a floor plate 61 consisting of
The end of the heat insulating material 58 is joined to the lower side surface of the wall panel 47 via a double span 60. Note that when configuring a floor with such a structure, a floor plate made of a highly rigid metal such as an iron plate may be used instead of the floor plate 61 made of FRP, but when using an iron plate as a floor plate, It is desirable to reduce the weight of the floor by using the thinnest steel plates possible.

When each room in the offshore warehouse 1 is constructed using such a floor, the floor can be constructed without using any concrete, so each room can be made lighter; As a result, it is possible to reduce the weight of the entire offshore warehouse 1. Therefore, it is possible to increase the carrying load within the offshore warehouse 1 having a predetermined scale (capacity), and thereby the storage capacity of the offshore warehouse 1 can be increased. The amount of possible cargo 8 can be increased.

Furthermore, other examples of floors include those shown in FIG.

As shown in FIG. 8, this floor is constructed by attaching a heat insulating material 58 made of polystyrene foam or the like on the steel beam 21, and placing a corrugated deck plate 62 on top of this insulating material 58. , a floor plate 61 made of fiber reinforced plastics (FRP) is attached on the deck plate 62, and the end of the heat insulating material 58 is attached to the lower side of the scattering panel 47 via an expander 60. They are joined together. In addition, even when configuring a floor with such a structure, a floor plate made of a highly rigid metal such as an iron plate may be used instead of the floor plate 61 made of FRP,
Even in that case, it is desirable to reduce the weight of the floor by using as thin an iron plate as possible.

When each room in the offshore warehouse 1 is configured using such a floor, even when a heavy load is placed on the floor plate 60, the recess of the insulation material 57 underneath is covered with the deck plate 61. can be prevented by the elasticity of
Even if the floorboard 60 above the deck plate 61 is dented by the weight of the cargo, when the cargo is moved to another location, the restoring force of the deck plate 61 will push up the dent in the floorboard 60. It can be restored.

When each room in the offshore warehouse is configured with the ceiling, walls, and floor as explained above, the columns, beams, outer walls, etc. of the offshore warehouse may be distorted or twisted due to external environmental forces such as waves, wind, and currents. Even if this occurs, the joints between the ceiling and walls and the joints between the walls and floors of each room in the offshore warehouse will not be misaligned (therefore, cold air will not flow through the gaps between those joints). Since there is no escape, the airtightness inside each room in the offshore warehouse can always be maintained in a good condition and excellent insulation performance can be maintained at all times. By configuring each of the rooms, the offshore warehouse has sufficient functionality as a low-temperature warehouse such as a refrigerated warehouse or a frozen warehouse.

On the other hand, as shown in FIG.
It is a fixed member that is fixed at a total of three locations (mooring part)
The offshore warehouse 1 is moored via link rods 12, respectively.

As shown in FIG. 11, the fixing member 11 includes a frame 13 fixed to the quay 4 or the dolphin 10, and a cell-type rubber fender 14 attached to the inside of the frame 13.
(elastic material) and a substrate 15 attached to the cell-type comfenter 14. A fixing rod 16 is attached to the substrate 15,
The mooring member 3 is attached to the tip of the fixed iron 16. This mooring member 3 has a link rod 12
and universal joints 17.17 at both ends thereof, each universal joint 17.
17 is connected to the tip of the fixing rod 16 on the side of the above-mentioned fixing member 11 and the tip of the fixing rod 18 on the offshore warehouse 1 side, respectively.

Further, the dolphin 10, as shown in FIG.
A position a predetermined distance from the side of the offshore warehouse l (the side determined corresponding to the front and rear when the end on the apron 6 side is defined as the front and the end moored to the quay wall 4 is defined as the rear) It is installed in a fixed state on the seabed 19, and its upper part is exposed to the ocean 2.

In such a mooring mechanism for the offshore warehouse 1, the link rod 12 connecting the quay 4 and the dolphin 10 to the offshore warehouse 1 is configured to be swingable in any direction, so that the mooring mechanism shown in FIGS. 12 and 13 is In this way, the offshore warehouse 1 can be moored while following the vertical movement due to tidal level fluctuations. Two fixing members 11 are provided on the quay wall 4, and a fixing member is also provided on the dolphin 10 on the side of the offshore warehouse 1. By connecting and mooring the offshore warehouse 1, the horizontal movement range of the offshore warehouse 1 is significantly restricted, and even when external environmental forces such as waves, wind, and currents are applied, the horizontal movement of the offshore warehouse 1 is kept extremely small. Therefore, the offshore warehouse 1 and the quay 4 can be constantly communicated via the connecting bridge 20 (see FIG. 10), thereby facilitating access by trucks and the like from land.

Furthermore, since the base plate 15 of the fixing member 11 to which the fixing rods 14 on the quay wall 4 side and the dolphin 10 side are attached is attached to the frame 13 of the fixing member 11 via the cell-type rubber fender 14, the Also, the inertial force due to seismic acceleration of the quay 4 and dolphin 10 is absorbed by the elastic material, and the inertial force transmitted to the fixed rod 16 and link rod 12 is attenuated, thereby reducing the vibration of the offshore warehouse 1 during an earthquake. will be suppressed.

In addition, when using such an offshore warehouse 1, for example, if the cargo is citrus fruits, etc., the cargo is transferred to pallets in the hold of the cargo ship 5 in advance, and the cargo is palletized using the ship's crane or shore crane. The cargo is unloaded from the cargo ship 5 and carried into the offshore warehouse 1 by lifting it directly onto the apron 6 of the offshore warehouse 1 and moving it horizontally to the first floor of the offshore warehouse 1 using a forklift. Do this in quick succession.

In addition, when constructing this offshore warehouse l, the floating structure that will become the main body of the offshore warehouse l will be manufactured in the dry dock, and after constructing the dolphin 10 on site, the floating structure will be transported to the site by towboat etc. It will be towed and installed by mooring it to the local quay 4 and dolphin 10.

In addition, since it is necessary to ensure sufficient buoyancy for such offshore warehouses like a ship at sea, it is difficult to make them from concrete due to the weight, and currently the only option is to make them from steel. It is considered. Therefore, when installing such offshore warehouses on the sea, in order to prevent corrosion of the outer walls (and roofs, aprons, etc.) due to salt adhesion caused by sea breezes and waves, it is necessary to use corrosion-resistant steel materials to prevent corrosion of the outer walls (and rooftops, aprons, etc.). It is necessary to take anti-corrosion measures (anti-rust measures) such as using strong steel or painting the surface with highly anti-corrosive paint. In addition, if it is necessary to consider not only the corrosion prevention effect but also the heat resistance effect against direct sunlight, synthetic resins such as epoxy resin and acrylic resin, or fiber reinforced plastics using these as materials (
It is desirable to coat the surfaces of external walls (and rooftops, aprons, etc.) with FRP.

"Effects of the Invention" According to the structure of the ceiling in an offshore warehouse of the present invention, a plurality of rectangular heat insulation panels are connected to form the ceiling of each room in an offshore warehouse moored floating on the ocean. , and some of the connecting parts of each of these insulation panels are connected through elastic material, and both ends are connected to the upper part of the wall of each room through the elastic material. A plurality of the heat insulating panels of the heat insulating panels are vertically movable and rotatable via a plurality of spring fingers attached to the steel beam above the steel beam. Because it was suspended, the pillars, beams, outer walls, etc. of the offshore warehouse could become distorted due to external environmental forces such as waves, wind, and currents.
Even if twisting occurs, the ceiling of each room in the offshore warehouse can be suspended in a stable state without being damaged by bending, and the connections between the insulation panels that make up the ceiling and It also prevents the cold air from escaping due to misalignment at the joint between the ceiling and the wall, thereby keeping the interior of each room in the offshore warehouse in a good condition at all times. Excellent heat insulation performance can be maintained at all times. Therefore, if each room in the offshore warehouse is configured by applying the ceiling structure in the offshore warehouse of the present invention, even if the offshore warehouse is used as a low-temperature warehouse such as a cold storage or a frozen warehouse, the It is possible to obtain sufficient functions as a low-temperature warehouse.
