Description

Technical Field

[0001] The present invention relates to a satellite camouflage material intake device and an intake method for taking in materials into a temporary facility while concealing and disguising the design information of a building from a satellite.

Background Art

[0002] In recent years, the number of artificial satellites has increased rapidly to about 11,000 to 14,000 as of 2025 - 2026, and buildings under construction are also becoming easily observable from satellites. Also, satellite images used to be extremely expensive and only accessible to government agencies and some large enterprises. Currently, however, through cloud platforms and APIs, general software developers and startup companies can easily purchase satellite images at a unit price of "several hundred yen to several thousand yen per square kilometer" and incorporate them into their own applications. As a result, the civilian use of satellite images has been promoted, and it is becoming possible to easily grasp the status of buildings under construction in temporary facilities such as temporary enclosures and temporary scaffolds.

[0003] In particular, when using the caisson method of constructing underground structures on land and then excavating and burying them, there is a problem that if monitored by an artificial satellite, the wall thickness of the underground structure and other information can be easily grasped by others. The design information such as the wall thickness and material of the underground structure is important information for grasping the penetration power of underground penetrating bombs such as bunker busters. That is, since the penetration depth of an underground penetrating bomb depends on the mass, the small cross-sectional area (cross-sectional load), and the bullet body toughness that does not collapse under impact (special steel for gun barrels, etc.), if the wall thickness and material of the underground structure are known, the approximate resistance to underground penetrating bombs can be grasped, which is a problem.

[0004] Therefore, the applicant of the present application has come up with a satellite camouflage temporary facility that can be constructed so that design information such as the wall thickness and material of a building cannot be easily grasped from an artificial satellite by not only covering the outside of the building's outer wall with a temporary facility such as a temporary enclosure or a temporary scaffold but also covering the airspace above the building's outer wall while constructing the building.

[0005] However, covering the exterior walls of a building with temporary facilities presents a problem: it becomes difficult to transport building materials such as formwork, reinforcing bars, and scaffolding materials using cranes and other lifting equipment. To solve this problem, one could consider installing an opening and closing device at the upper entrance used to transport materials into the temporary facilities from above using lifting equipment. However, this would create a problem where design information such as the wall thickness and materials of the building under construction could be leaked by satellite images while the opening and closing device is open during material transport.

[0006] For example, Patent Document 1 discloses a load lifting and retrieval device for scaffolding in construction sites, etc., in which mounting seats are provided at both ends of the column of the load lifting device, a jib is provided protruding from the front side of the column, and a pulley for passing a lifting wire rope is provided on the jib, and the device is rotatably attached by a pivot shaft to a support seat of a receiving girder, and an armed return spring is interposed between the mounting seats and the support seat of the receiving girder (see Claim 1 and Figure 1 of the claims of Patent Document 1, etc.).

[0007] Furthermore, Patent Document 2 discloses a method for bringing goods into a building using a crane, characterized in that a beam is suspended from the hook of the crane, the goods to be brought in are suspended from the center of the beam via a movable lifting means, the goods to be brought in are lifted together with the beam by crane operation to near the entrance, the tip of the beam is held horizontally by a support fitting provided on the ceiling or wall of the entrance, and the suspended load is brought into the building by moving the movable lifting means horizontally along the beam in that state (see Claim 1 of the claims in Patent Document 2, paragraphs

[0006] and

[0007] of the specification, and Figures 1 and 2 of the drawings).

[0008] However, neither the cargo lifting and retrieval device described in Patent Document 1 nor the method for retrieving goods using a crane described in Patent Document 2 contained any idea of ​​concealing and falsifying the design information of a building from artificial satellites. Therefore, even if the inventions described in Patent Documents 1 and 2 were applied to the retrieval of materials for a temporary facility that blocks surveillance from artificial satellites, it would not solve the problem of design information such as the wall thickness and material of the building under construction being imaged and leaked by artificial satellites during material retrieval.

[0014] The satellite-camouflaged material intake method according to the fourth invention is a satellite-camouflaged material intake method that involves covering at least the airspace above the outer wall of a building under construction with a temporary facility to conceal and camouflage the design information of the building, and taking in materials through an opening for material intake provided on the upper surface of the temporary facility, characterized in that when the upper opening / closing device of at least two stages of opening / closing devices, consisting of an upper opening / closing device and a lower opening / closing device provided in the opening, is open, the lower opening / closing device is closed.

[0018] In particular, according to the second invention, since the opening and closing directions are different, by configuring so that the flow lines during opening and closing do not overlap, the opening and closing operations within the temporary facilities with limited space can be easily and efficiently performed.

[0019] In particular, according to the third and sixth inventions, after taking in materials into the temporary facilities with the satellite disguise material intake device, the distribution and movement of the materials can be efficiently performed in a short time.

[Modes for carrying out the invention]

[0021] Hereinafter, one embodiment of the satellite disguised material acquisition device and acquisition method according to the present invention will be described in detail with reference to the drawings.

[0022] [Satellite-disguised temporary facility] Figures 1 to 8 illustrate the satellite disguise temporary facility 1 according to an embodiment of the present invention. The explanation will illustrate a case where an underground structure is constructed using the pneumatic caisson method, which involves constructing a caisson frame 10 on the ground, providing an airtight work chamber below the caisson frame, supplying compressed air to remove groundwater, and then excavating the ground of the work chamber in a dry environment to sink the caisson frame. Figure 1 is a perspective view of the satellite disguise temporary facility 1 as seen from the south. Figure 2 is a vertical cross-sectional view showing a standard cross-section of the satellite disguise temporary facility 1. As shown in Figures 1 and 2, the satellite disguise temporary facility 1 is a temporary facility that covers at least the airspace above the outer wall of a building in order to conceal design information such as the wall thickness and material of the building from being easily grasped by satellite photography, etc.

[0023] As shown in Figure 1, the satellite disguised temporary facility 1 is a temporary facility in a plan view that is shaped like a square in plan view, consisting of a south-facing facility, an east-facing facility, a north-facing facility, and a west-facing facility, installed along the outer wall of the building to be constructed, i.e., the outer wall portion 10b of the caisson structure 10. The structure of the west-facing and east-facing facilities of the satellite disguised temporary facility 1, and the structure of the parts of the south-facing and north-facing facilities that do not come into contact with the soil removal equipment 11 such as soil removal carriers, shall be a structure consisting of a standard cross-section of standard type 1a as shown in Figure 2. The structure of the parts 1b of the caisson structure 10 of the south-facing and north-facing facilities that come into contact with the soil removal equipment 11 shall be a structure in which the support structures such as main girders and bents are eliminated and the disguised material is spread out to a maximum span of 9m, as will be described later. Note that in the figure, reference numeral 12 denotes a tower crane 12, and reference numeral 13 denotes a material lock (or man lock) 13.

[0024] As shown in Figure 2, the caisson structure 10, which is constructed as a building, is a reinforced concrete structure in which a rectangular base plate 10a is surrounded by an outer wall section 10b that is shaped like a square in plan view. Of course, the shape of the caisson structure 10 is not limited to rectangular or square shapes, but can be various shapes such as circular or oval.

[0025] The standard cross-section of the satellite disguised temporary facility 1 consists of an inner scaffolding 2 and an outer scaffolding 3 installed along the outer wall portion 10b of the caisson structure 10, a temporary support bent 4 installed on the inner scaffolding 2, a multi-bent 5 installed on the outside of the outer scaffolding 3, a main girder member 6 spanning over the temporary support bent 4 and the multi-bent 5, and a disguised roofing material 7, which is a disguise material installed on the main girder member 6.

[0026] (Inner scaffolding and outer scaffolding) The inner scaffolding 2 and outer scaffolding 3 are frame scaffolding consisting of a frame structure combined with bracing and bracing. However, the inner scaffolding 2 and outer scaffolding 3 may be other temporary scaffolding, such as wedge-type scaffolding, that can be used to carry out construction work such as the installation of formwork for the outer wall section 10b.

[0027] (Temporary support vent) The temporary support bent 4 is a temporary support column for supporting the main girder 6 installed on the inner scaffolding 2. As shown in Figure 2, the temporary support bent 4 according to this embodiment is made up of temporary materials such as frame scaffolding, wedge-type scaffolding, and adjustable scaffolding, and steel materials such as H-shaped steel, and has the function of adjusting the height so that the main girder 6 on which it is placed is horizontal, and supporting the main girder 6. However, if the materials are not lifted by a chain block 8 or the like, it is also possible to support the main girder 6 in a cantilever structure using only the multi-bent 5.

[0028] (Multivent) The multi-bent 5 according to this embodiment is, for example, a foldable temporary support column manufactured by Nissho Sangyo Co., Ltd. that can support approximately 240 tons per bent (60 tons per support column). The multi-bent 5 has a built-in climbing ladder and work platform, and can be used immediately after opening, thus ensuring a safe working space and excellent workability. Note that the multi-bent 5 is not limited to a foldable bent, and may be constructed using temporary materials such as frame scaffolding or wedge-type scaffolding.

[0029] This multi-bent 5 is assembled by laying a base beam 50 made of H-shaped steel (for example, H-300×300×10×15) on the bottom and then installing a jack base 51 on top of it. This is to distribute the load on the ground using the base beam 50.

[0030] Additionally, a jack base 51 is installed on top of the multi-bent 5, making it easy to adjust the height so that the main beam member 6 on which it is placed is horizontal.

[0031] (Main girder material) The main girder member 6 is made of steel such as H-shaped steel and is a steel material that resists stresses such as snow load acting on the false roofing material 7, as well as stresses acting when lifting materials used via the chain block 8 described later, and is installed with its length perpendicular to the outer wall section 10b. In this embodiment, the main girder member 6 is assumed to be, for example, an H-shaped steel with dimensions of H-800 × 300 × 14 × 26 and a length of 12m.

[0032] It is preferable that the main girder member 6 is installed via a support member 60 and a receiving member 62, or either one thereof, made of steel or the like, which are placed on the temporary support bent 4 and the multi-bent 5. This is because the load on the main girder member 6 can be distributed and transmitted to the temporary support bent 4 and the multi-bent 5. In this embodiment, the support member 60 and the receiving member 62 are assumed to be, for example, H-shaped steel of H-300×300×10×15.

[0033] Furthermore, as shown in Figure 2, rail-shaped rail members 61 made of steel such as H-shaped steel are suspended and fixed to the main girder member 6 along the outer wall portion 10b in their longitudinal direction, and the chain block 8 is able to slide freely along the rail members 61.

[0034] (Disguised roofing material) The disguised roofing material 7 is a disguised material that conceals design information such as the wall thickness and materials of a building so that it cannot be ascertained by satellite photography, etc., and is a disguised material based on a folded sheet of a specified thickness (for example, 0.5 mm or more).

[0035] The disguised roofing material 7 according to this embodiment is envisioned to be based on a corrugated sheet metal such as a roof 88, which has a width of 600 mm, a height of 88 mm, and a length of 1600 mm and has a 30-minute fire resistance performance. However, the disguised roofing material 7 only needs to have sufficient strength to withstand anticipated snow loads, etc., and be made of a material that can block at least visible light from optical observation satellites. Furthermore, the disguised roofing material 7 may be created by attaching a disguise material that blocks visible light, etc., to the corrugated sheet metal, or by applying a special paint, etc., to the disguised roofing material 7.

[0036] However, the disguised roofing material 7 may be designed to block infrared rays such as near-infrared and thermal infrared rays, as well as microwaves with wavelengths longer than visible light. This would allow design information such as the thickness and material of the building's walls to be concealed from satellites equipped with infrared and microwave sensors.

[0037] Furthermore, as shown in Figure 2, the disguised roofing material 7 is installed on the main beam member 6 via the raising material 70 and roof support material 71 with a predetermined slope (for example, about 3%) such that the inside is higher, so that rainwater flows from the inside to the outside. This is to prevent rainwater from flowing into the caisson structure 10 side during rainfall. The roof support material 71 is a reinforcing steel material to withstand stresses such as snow load, and in this embodiment, an H-shaped steel (for example, H-150×150×7×10) is assumed.

[0038] (Chain block) The chain block 8 is a device that uses the principle of pulleys and gears to lift heavy objects such as materials by pulling a chain (hand chain) electrically or manually. The chain block 8 may also be other small lifting devices that slide along a rail material 61, such as a hoist that winds up a wire rope, instead of using a chain.

[0039] <Deception of a Lead-Faced Surface> First, the camouflage of the vertical surface of the satellite disguise temporary facility 1 will be explained using Figures 3 to 6. Figure 3 is a perspective view mainly showing the vertical surface of the west side of the satellite disguise temporary facility 1. Figure 4 is a perspective view mainly showing the vertical surface of the south side of the satellite disguise temporary facility 1, and Figure 5 is a magnified view of the south side of the facility showing the structure of the part 1b of the satellite disguise temporary facility 1 that is in contact with the soil removal equipment 11, with the soil removal equipment 11 removed.

[0040] As shown in Figure 3, the camouflage of the vertical surface of the western facility of the satellite disguise temporary facility 1, which is of standard type 1a, is carried out by attaching a sheet-like camouflage material, the camouflage sheet 9, to the outside of the aforementioned multi-vent 5 (see Figure 2). Although not shown, the camouflage of the vertical surface of the eastern facility of the satellite disguise temporary facility 1, which is of standard type 1a, is carried out in a similar manner.

[0041] The camouflage sheet 9 is a sheet-like camouflage material made of a material that can block at least visible light from the optical observation satellite. Preferably, it can block not only visible light but also infrared rays such as near-infrared rays and thermal infrared rays, as well as microwaves with wavelengths longer than visible light.

[0042] As shown in Figure 4, the camouflage of the vertical surface of the south-facing facility of the satellite disguised temporary facility 1, which is a standard type 1a that does not come into contact with the soil removal equipment 11, is carried out in the same way as the west-facing facility, by fastening and stretching the camouflage sheet 9 to the outside of the aforementioned multi-vent 5.

[0043] On the other hand, as shown in Figure 5, the camouflage of the vertical surface of the south face facility at the portion 1b of the satellite disguised temporary facility 1 that is in contact with the soil removal equipment 11 is structured so that the support structures such as the main girder members 6 and multi-bent 5 are eliminated, and the camouflage material is spread over a maximum span of 9m and supported by the adjacent standard type 1a. For this reason, the camouflage sheet 9 is stretched and deployed from the outside of the aforementioned outer scaffolding 3, wrapping around to a portion of the east and west faces of the adjacent multi-bent 5.

[0044] On the other hand, as shown in Figure 5, the camouflage of the vertical surface of the south face facility at the portion 1b of the satellite disguised temporary facility 1 that is in contact with the soil removal equipment 11 is structured so that the support structures such as the main girder members 6 and multi-bent 5 are eliminated, and the camouflage material is spread over a maximum span of 9m and supported by the adjacent standard type 1a. For this reason, the camouflage sheet 9 is stretched and deployed from the outside of the aforementioned outer scaffolding 3, wrapping around to a portion of the east and west faces of the adjacent multi-bent 5.

[0045] Furthermore, the camouflage sheets 9 are stretched not only on the outside of the outer scaffolding 3 or multi-vent 5, but also on the east, west, north, and south sides of the central part of the inner scaffolding 2 (temporary support vent 4). In other words, the camouflage material of the satellite disguised temporary facility structure 1 is installed on a total of three surfaces: the aforementioned camouflage roofing material 7 on the upper surface (horizontal plane), and the camouflage sheets 9 on the two vertical surfaces, inside and out. As a result, the satellite disguised temporary facility 1 is concealed from any angle in the east, west, north, or south directions.

[0046] As shown in Figure 6, the camouflage sheet 9 according to this embodiment has a double-layer structure consisting of an electromagnetic shielding sheet 90 provided on the inner surface and a general membrane material sheet 91 provided on the outer surface. This is because the electromagnetic shielding sheet 90 alone may not have sufficient durability against external forces such as wind loads. Figure 6 is a schematic diagram mainly showing the camouflage sheet 9, where (a) is a front view showing the inner surface, (b) is a vertical cross-sectional view, and (c) is a rear view showing the outer surface.

[0047] As shown in Figures 6(a) and 6(b), the electromagnetic shielding sheet 90 is provided with a tab 90a with a grommet 90b at its widthwise end, and is fixed to the support column of the multi-bent 5 using a connecting rope 92.

[0048] As shown in Figure 6(c), a cable 93, such as a structural strand rope (7 × 7 × φ20 mm), is inserted through the outer surface of the sheet material 91 in a bag-like shape to resist wind loads, and the upper and lower ends are secured with bearing plates 94.

[0049] However, the disguised sheet according to the present invention is not limited to the embodiments described above, and may be an electromagnetic shielding sheet alone, a perforated sheet alone, a mesh alone, or a combination thereof as described above.

[0050] <Camouflage on the top surface> Next, the camouflage of the upper surface of the satellite disguise temporary facility 1 will be explained using Figures 7 and 8. Figure 7 is a perspective view mainly showing the upper surface of the satellite disguise temporary facility 1. Figure 8 is a partially enlarged perspective view looking outward from above the inner scaffolding 2 (temporary support bent 4), mainly showing the support structure of the camouflage roof material 7 of the satellite disguise temporary facility 1.

[0051] The camouflage of the upper surface of the satellite-deceptive temporary facility 1 is carried out by covering and concealing both the standard type 1a that does not come into contact with the soil removal equipment 11 and the part 1b that comes into contact with the soil removal equipment 11 with the aforementioned camouflage roofing material 7 (see also Figure 2). The camouflage roofing material 7 is disguised in such a way that the design information cannot be obtained from the satellite by using the corrugated metal itself, or a camouflage sheet attached to the corrugated metal as a base, or a special paint applied to the upper surface of the corrugated metal as a base.

[0052] Furthermore, as shown in Figure 7, in addition to the disguised roofing material 7, an opening 1c for material intake is provided between the disguised roofing material 7 on the upper surface of the satellite disguised temporary facility 1. The disguise of the opening 1c will be described later.

[0053] As shown in Figures 2 and 8, the support structure for the disguised roofing material 7 is mainly composed of a support frame made of steel materials such as H-shaped steel arranged in a grid pattern. Inside this support frame, the support members 60 and support members 62 are arranged in a grid pattern on a temporary support bent 4 constructed on top of the inner scaffolding 2. On the other hand, outside the support frame, the support members 60 are installed on a multi-bent 5. Then, the main beam members 6 are laid across the temporary support bent 4 and the multi-bent 5 to construct the support frame for the disguised roofing material 7.

[0054] <Disguising the opening> Next, the camouflage of the opening 1c of the satellite disguise temporary facility 1 will be explained using Figures 7 and 9. Figure 9 is a partially enlarged perspective view looking outward from above the inner scaffolding 2 (temporary support vent 4), mainly showing the structure of the opening 1c of the satellite disguise temporary facility 1. However, in Figure 9, the central temporary support vent 4 and the inner scaffolding 2 are omitted in order to make the structure of the opening 1c easier to understand.

[0055] As shown in Figure 7, the openings 1c of the satellite disguised temporary facility 1 are provided in two locations each on the south-facing facility, east-facing facility, north-facing facility, and west-facing facility, which are installed along the outer wall portion 10b of the caisson structure 10. Therefore, materials and other suspended loads SL can be brought into each of the south-facing, east-facing, north-facing facility, and west-facing facility of the satellite disguised temporary facility 1 using the tower crane 12.

[0056] [Satellite camouflage material acquisition device] Next, the satellite-camouflaged material intake device 100, which is installed in the opening 1c of the satellite-camouflaged temporary facility 1, will be described. As shown in Figures 9 and 10, the satellite-camouflaged material intake device 100 is installed in this opening 1c, and the satellite-camouflaged material intake device 100 consists of two stages of opening and closing devices: an upper opening and closing device 15 and a lower opening and closing device 16. The opening and closing operations of the upper opening and closing device 15 and the lower opening and closing device 16 of the satellite-camouflaged material intake device 100 are configured to be linked. When the upper opening and closing device 15 is open, the lower opening and closing device 16 is closed, concealing and camouflaging the device so that the design information of the building cannot be obtained from the satellite.

[0057] As shown by the arrows in the figure, the upper opening and closing device 15 has a pair of sliding doors 17 that can be electrically opened and closed in a double-door manner along the outer wall portion 10b of the caisson structure 10, which is the building. The upper opening and closing device 15 may also consist of a single sliding door that can be electrically or manually opened and closed along the outer wall portion 10b, rather than double doors.

[0058] The lower opening / closing device 16 consists of one or more divided blindfolds 18, which are sheet-like camouflage materials similar to the camouflage sheet 9. By pulling a rope or the like attached to the end of the blindfold 18, it can be opened and closed in a sliding manner perpendicular to the outer wall 10b, as shown by the arrow in the figure. Of course, the lower opening / closing device 16 may be opened and closed electrically instead of manually.

[0059] This satellite-camouflaged material intake device 100 is configured such that, with the upper opening / closing device 15 open, the suspended load SL of materials is temporarily stored in the space between the upper opening / closing device 15 and the lower opening / closing device 16. Then, with the upper opening / closing device 15 closed, the lower opening / closing device 16 can be opened by manually pulling the rope to open the blind curtain 18, allowing the suspended load SL to be lowered further. When hoisting up the suspended load, the procedure is reversed. That is, with the upper opening / closing device 15 closed, the lower opening / closing device 16 is opened, the suspended load is lifted upwards and temporarily stored between the upper opening / closing device 15 and the lower opening / closing device 16, then the lower opening / closing device 16 is closed, and the upper opening / closing device 15 is opened to remove the suspended load from the satellite-camouflaged temporary facility structure 1.

[0060] Thus, when the upper opening / closing device 15 of the satellite-disguised material acquisition device 100 is open, the lower opening / closing device 16 is closed, preventing the acquisition of design information such as the wall thickness and material of buildings from artificial satellites.

[0061] Furthermore, as shown in Figures 2 and 10, the main girder member 6 is suspended and fixed so that the longitudinal direction of the rail member 61 follows the outer wall portion 10b, and the chain block 8 can slide freely along the rail member 61 using an electric trolley or the like, thus forming a so-called overhead crane. As a result, suspended loads SL of materials brought into each of the facilities of the south, east, north, and west sides of the satellite disguised temporary facility 1 through the opening 1c can be distributed or moved in the vertical direction and horizontal direction along the outer wall portion 10b using the chain block 8 in a short time and efficiently. Figure 10 is a perspective view showing the lower internal structure of the satellite disguised temporary facility 1.

[0062] [Method for incorporating satellite disguise materials] Next, the opening and closing operation of the satellite disguised material collection device 100 and the satellite disguised material collection method according to an embodiment of the present invention will be described using Figure 11. Figures 11(a) to 11(h) are partially enlarged perspective views showing the procedure for the opening and closing operation of the satellite disguised material collection device 100 and the satellite disguised material collection method according to this embodiment.

[0063] As shown in Figure 11(a), first, in the satellite disguised material acquisition method using the satellite disguised material acquisition device 100, the suspended load SL of materials is lifted using the tower crane 12 (see Figure 7, etc.) and moved directly above the satellite disguised material acquisition device 100 (opening 1c).

[0064] Subsequently, as shown in Figure 11(b), the pair of left and right sliding doors 17 of the upper opening / closing device 15 of the satellite disguised material intake device 100 are operated and opened in a double-door manner in the direction of the arrows in the figure, along the outer wall portion 10b.

[0065] At this time, as shown in Figure 11(b), the opening 1c is closed by the cover curtain 18 of the lower opening / closing device 16, concealing and disguising it so that the building's design information cannot be obtained from a satellite.

[0066] Next, as shown in Figure 11(c), the suspended load SL is lowered using the tower crane 12 (see Figure 7, etc.) to a space below the sliding door 17 and directly above the blind curtain 18, and then temporarily stored in the space between the upper opening / closing device 15 and the lower opening / closing device 16.

[0067] Next, as shown in Figure 11(d), the pair of left and right sliding doors 17 of the upper opening / closing device 15 are activated, and the sliding doors 17 are slid in the direction of the arrow in the figure, along the outer wall portion 10b, to close the upper opening / closing device 15.

[0068] Figures 11(e) and 11(f) show the state in which the suspended load SL is stored in the space between the upper opening / closing device 15 and the lower opening / closing device 16. As shown in Figures 11(e) and 11(f), in the satellite disguised material intake device 100 according to this embodiment, the space between the upper opening / closing device 15 and the lower opening / closing device 16 is set to a height of approximately 2m, taking into consideration the size of the materials to be brought in.

[0069] Next, as shown in Figures 11(e) and 11(f), after confirming that the sliding door 17 of the upper opening / closing device 15 is completely closed, the blind curtain 18 of the lower opening / closing device 16 is opened as shown in Figure 11(g). Specifically, by pulling a rope or the like attached to the end of the blind curtain 18, the blind curtain 18 is folded and opened in a sliding manner perpendicular to the outer wall 10b, exposing the lower internal space inside the satellite disguised material intake device 100 so that the suspended load SL can be lowered further downward.

[0070] Next, as shown in Figure 11(h), the suspended load SL is lowered using the tower crane 12 (see Figure 6, etc.) to a height below where the blindfold curtain 18 was installed, and temporarily placed in a suitable location such as the outer wall portion 10b of the caisson structure 10.

[0071] Subsequently, using the lifting devices shown in Figure 10, such as the chain block 8 and electric trolley, the temporarily placed suspended load SL is slid horizontally along the outer wall 10b or moved vertically to perform distribution and movement as needed. Therefore, after the materials, which are the suspended load SL, are brought into the satellite disguised temporary facility 1 by the satellite disguised material intake device 100, distribution and movement can be performed efficiently in a short amount of time.

[0072] When hoisting the suspended load SL, the procedure is reversed. That is, with the upper opening / closing device 15 closed, the lower opening / closing device 16 is opened, the suspended load is lifted upwards, temporarily stored between the upper opening / closing device 15 and the lower opening / closing device 16, then the lower opening / closing device 16 is closed, the upper opening / closing device 15 is opened, and the suspended load is removed from the satellite disguised temporary facility 1.

[0073] According to the satellite-camouflaged material acquisition device 100 and satellite-camouflaged material acquisition method using the present embodiment described above, it is possible to safely and efficiently acquire materials from the outside without compromising confidentiality even for a moment, while concealing and camouflaging the device within the satellite-camouflaged temporary facility 1 so that the design information of the building under construction cannot be grasped from the satellite, and at the same time acquiring the materials.

[0074] Furthermore, according to the satellite disguised material intake device 100, the upper opening / closing device 15 and the lower opening / closing device 16 are configured so that their opening and closing directions are perpendicular to each other, so that the movement paths during opening and closing do not overlap, and opening and closing operations can be easily and efficiently performed inside the satellite disguised temporary facility 1 below the narrow opening 1c.

[0075] Furthermore, in the standard type 1a of the satellite disguised temporary facility 1, rail members 61 are suspended and fixed along the outer wall section 10b from the main girder members 6, and the chain block 8 is slidable along the rail members 61. In addition, according to the satellite disguised material intake method, the chain block 8, which is slidably attached to the rail members 61, is used to slide the temporarily placed materials. Therefore, the suspended load SL of materials such as materials taken into the satellite disguised temporary facility 1 through the opening 1c can be distributed or moved in the vertical direction and horizontal direction along the outer wall section 10b using the chain block 8 in a short time and efficiently.

[0076] Furthermore, according to the satellite-deceptive temporary facility 1, the south-facing facility, east-facing facility, north-facing facility, and west-facing facility are installed along the outer wall portion 10b of the caisson structure 10, and their upper surfaces are covered and concealed with deceptive roofing material 7. As a result, it is possible to construct a building in such a way that design information such as the wall thickness and material of the outer wall portion 10b of the caisson structure 10, which is a building, cannot be easily obtained from an artificial satellite.

[0077] Furthermore, according to the satellite-deceptive temporary facility 1, not only the upper surface of the outer wall section 10b, but also along the outside of the south-facing facility, east-facing facility, north-facing facility, and west-facing facility, a sheet-like deceptive material called a deceptive sheet 9 is installed, providing vertical deception. As a result, even as construction of the building progresses, design information such as the wall thickness and materials of the building cannot be obtained from outside the temporary enclosure or from artificial satellites.

[0078] Furthermore, according to the satellite disguise temporary facility 1, a foldable multi-vent 5 with a built-in climbing ladder and work platform is used as a temporary support column. Therefore, the multi-vent 5, which is delivered in a folded state, can be used immediately after being opened. This ensures a safe working space when installing the satellite disguise temporary facility and improves work efficiency during the construction of the temporary facility.

[0079] The satellite disguised material acquisition device 100, the satellite disguised material acquisition method using the same, and the satellite disguised temporary facility 1 according to this embodiment have been described in detail above. However, the embodiments described above or illustrated are merely examples of embodiments that have been materialized in carrying out the present invention. Therefore, the technical scope of the present invention should not be interpreted as being limited by these embodiments.

[0080] In particular, the caisson structure 10 was used as an example to explain how to construct a building while concealing and disguising it as a satellite-deceptive temporary facility 1. However, this method is not limited to the caisson structure 10, and can be applied to any building that needs to be constructed in a way that prevents its design information from being obtained.
