Description

[Technical field]

[0001] The present invention relates to a mobile installation building that can be moved and installed, and a mobile installation method for the mobile installation building. [Background technology]

[0002] In recent years, there has been an increasing need for trailer houses and container houses that can be used as emergency temporary buildings in the event of a disaster. For example, Patent Document 1 discloses a container house that includes a container that is equipped with a bottom plate, a front plate fixed to the bottom plate, front legs, rear legs with rollers, and a hook member fixed to the front plate and is configured to be freely attached to and detached from a vehicle equipped with a container detachment device, and a house fixed on the bottom plate. Patent Document 2 discloses a container house that includes a rectangular parallelepiped unit including a rectangular steel frame formed by joining ceiling girders, floor girders, floor beams, and columns, a ceiling plate attached to the ceiling part of the steel frame, an exterior wall plate attached to the wall part of the steel frame, a floor plate attached to the floor part of the steel frame, and a zinc-containing layer formed on the outer surface of the ceiling girders, floor girders, floor beams, columns, ceiling plate, and exterior wall plate.

[0003] [Patent Document 1] JP 2007-277840 A [Patent Document 2] Patent Publication No. 2021-31929 Summary of the Invention [Problem to be solved by the invention]

[0004] However, trailer houses are not suitable for mid- to long-term continuous installation, as they need to be kept mobile. Container houses are preferable when considering improvements in building performance and short-term and mid- to long-term continuous installation, but the foundations of container houses must comply with the Building Standards Act. In that case, the foundations must be made of concrete, which requires heavy machinery and large-scale construction. Also, when a mobile building is removed, only the foundations remain, which is a major constraint when considering land utilization.

[0005] To provide a movable and installed building and a movable and installed method for the movable and installed building, which can fabricate a building foundation without requiring heavy machinery and also eliminates the need for dismantling work required for concrete foundations. [Means for solving the problem]

[0006] The removably installed building of the present invention is characterized by comprising a building body that can be moved and installed, a column base positioned at the bottom of the building body, and a weight material that acts as a weight on the column base while being removable from the column base.

[0007] With the above-mentioned configuration, the resistance to the pull-out force applied to the column base due to the horizontal force applied to the mobile-installed building body is obtained by applying the weight of the weight material to the column base. In other words, since the foundation of this mobile-installed building is made of the weight material, the equipment and heavy machinery required for the construction of a concrete foundation are not required. Meanwhile, since the weight material can be removed from the column base, the dismantling work required for a concrete foundation is also not required.

[0008] The column base may have a bottom plate at a lower end thereof that protrudes laterally from the outer periphery of the column base, which makes it possible to easily carry out the work by simply placing the weight material on the bottom plate without needing to hook the weight material onto the column base.

[0009] A wall member may be disposed surrounding the periphery of the column base and the bottom plate, and the weight material may be present within the wall member, which makes it easy to apply the weight of the weight material in a concentrated manner to the bottom plate.

[0010] A pressing plate for pressing the weight material downward may be provided at a portion of the column base located above the weight material, whereby the weight material can withstand the compressive force acting on the column base due to the horizontal force acting on the building body via the pressing plate.

[0011] The column base may have a protrusion protruding toward the weight material on the periphery of the column base. In this way, resistance to the pull-out force acting on the column base can be obtained by the weight of the weight material being applied to the protrusion. In addition, the compressive force acting on the column base due to the horizontal force acting on the building body can be received by the weight material via the protrusion.

[0012] The wall member may have a wall-side protrusion on an inner wall thereof that protrudes toward the weight material, whereby the wall-side protrusion also acts as a resistance against a pull-out force applied to the column base.

[0013] The mobile-installation building may also include a bridge bottom plate disposed across the adjacent bottom plates, and the weight material may also be present on the bridge bottom plate. In this way, resistance to the pull-out force applied to the column base can also be obtained by the weight of the weight material being applied to the bridge bottom plate.

[0014] The method for moving and setting up a mobile building of this invention is characterized by comprising the steps of loading the building body onto the bed of a vehicle and moving it, attaching a column base to the lower part of the building body at the destination of the building body, and arranging a weight material that acts as a weight on the column base but can be removed from the column base.

[0015] With this method, a building body such as a container house is loaded onto the bed of a vehicle and moved, and the column base is attached to the bottom of the building body at the destination, so that the building body can be moved and set up easily and quickly. The resistance to the pull-out force applied to the column base due to the horizontal force applied to the moved and set up building body is obtained by applying the weight of the weight material to the column base. Meanwhile, since the weight material can be removed from the column base, demolition work such as that required for concrete foundations is not required.

[0016] In the above method, the height position of the vehicle's loading platform may be raised, a column base may be attached to the lower side of the building body mounted on the loading platform, and then the height position of the vehicle's loading platform may be lowered to place the column base on the ground and remove the vehicle from the building body. This eliminates the need to use a crane to install the building body on the ground, making it possible to easily and inexpensively install a mobile building even in places where a crane cannot enter. Effect of the Invention

[0017] According to the present invention, it is possible to fabricate a foundation without the need for heavy machinery, and there is also the effect that demolition work required for concrete foundations is also unnecessary. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0019] Hereinafter, an embodiment according to one aspect of the present invention will be described with reference to the accompanying drawings. As shown in Fig. 1, the method for moving and setting up a mobile-installed building 1 according to the embodiment includes a step of loading a building main body 1a onto a loading platform 81 of a vehicle 8 and moving the building main body 1a. The building main body 1a is, for example, a mobile home using a container, a mobile office, a temporary residence in the event of a disaster, etc. As the vehicle 8, for example, a container truck is used.

[0020] This moving and setting method includes a step of attaching the column base 2 to the vicinity of the four corners of the lower part of the side of the building main body 1a at the moving destination of the building main body 1a. In this step, the loading platform 81 of the vehicle 8 is jacked up to raise the height position of the building main body 1a mounted on the vehicle 8. The height position of the loading platform 81 may be raised by adjusting the amount of compressed air injected into the air suspension of the vehicle 8. In attaching the column base 2, the mounting part 21 on the upper side of the column base 2 is fixed to the fixing part located at the four corners of the lower part of the side of the building main body 1a with a bolt or the like. The mounting part 21 protrudes horizontally from the fixing part of the building main body 1a so that the column base 2 can avoid the loading platform 81 and be grounded. At least the upper side of the column base 2 has a cylindrical shape, and a male screw part is formed on the upper side, and a nut 22 is screwed into the male screw part.

[0021] After the column base 2 is attached to the fixed portion of the building main body 1a, the connection between the building main body 1a and the loading platform 81 is released, and the loading platform 81 is jacked down to bring the column base 2 into contact with the ground. The height of the loading platform 81 may be lowered by adjusting the amount of compressed air injected into the air suspension of the vehicle 8. The column base 2 has a bottom plate 23 at the lower end of the column base 2 that protrudes laterally from the outer periphery of the column base 2, and this bottom plate 23 comes into contact with the ground. Once the column base 2 has been brought into contact with the ground, the vehicle 8 is detached from the building main body 1a.

[0022] Next, a wall member 3 is installed on the ground so as to surround the column base 2. The wall member 3 can be made of a cage, cylindrical precast concrete, steel pipe, or the like. The cylindrical precast concrete or steel pipe is divided into a number of parts, and these parts are joined together to form a cylinder. Then, weight material 4 is poured into the wall member 3 until it reaches the vicinity of the upper end of the wall member 3. The weight material 4 is a material that acts as a weight for the column base 2, but can also be removed from the column base 2, such as sand, gravel, or stone. It is preferable to procure such materials at the destination.

[0023] Next, for example, a pressing plate 25 having a notch cut from the periphery toward the center with a width equal to or greater than the width of the pedestal 2 is placed on the weight material 4 in the wall member 3, and the pedestal 2 is inserted into the notch to position the pedestal 2 at the center of the pressing plate 25. Then, the nut 22 screwed onto the pedestal 2 is turned to press the pressing plate 25 downward.

[0024] In the above mobile installation method, the building body 1a such as a container house is loaded on the loading platform 81 of the vehicle 8 and moved, and the column base 2 is attached to the lower part of the building body 1a at the destination of the moving of the building body 1a, so that the building body 1a can be easily and quickly moved and installed to create the mobile-installed building 1. In addition, the resistance against the pull-out force applied to the column base 2 due to the horizontal force applied to the moved and installed building body 1a is obtained by the weight of the weight material 4 being applied to the column base 2. On the other hand, since the weight material 4 can be removed from the column base 2, dismantling work such as that required for a concrete foundation is not required. In addition, when the mobile-installed building 1 is further moved to another location, the weight material 4 such as sand or stones can be returned to the source of supply without being moved, or can be used for leveling the ground if there is a demand for leveling the ground.

[0025] In addition, in this embodiment, the height position of the loading platform 81 of the vehicle 8 is raised, and the column base 2 is attached to the lower side of the building main body 1a mounted on the loading platform 81. Then, the height position of the loading platform 81 is lowered to place the column base 2 on the ground, and the vehicle 8 is detached from the building main body 1a. This eliminates the need to use a crane to install the building main body 1a on the ground, and makes it possible to easily and cheaply move and install the mobile-installation building 1 even in places where a crane cannot enter.

[0026] As described above, the removably installed building 1 includes a building main body 1a that can be moved and installed, a column base 2 located at the lower part of the building main body 1a, and a weight material 4 that acts as a weight on the column base 2 and can be removed from the column base 2. In this embodiment, the column base 2 has a bottom plate 23 at its lower end, so there is no need to hook the weight material 4 on the column base 2, and the weight material 4 can be placed on the bottom plate 23, making the work easier. In addition, in the removably installed building 1, a wall member 3 is arranged surrounding the column base 2, and if the weight material 4 is present inside the wall member 3, it becomes easy to apply the weight of the weight material 4 to the bottom plate 23 in a concentrated manner.

[0027] Here, in the movable-installed building 1 having the bottom plate 23 and the wall member 3, as shown in FIG. 2, the overturning moment M with respect to the horizontal force H applied to the movable-installed building 1 can be expressed by the following formula 1. The overturning moment M satisfies the inequality condition of the following formula 1 with respect to the moment resisting overturning due to the self-weight W of the building main body 1a. Note that the first term (W×(a / 2)) on the right side of the inequality of formula 1 is the moment resisting overturning due to the self-weight W of the building main body 1a, and the second term (g×a×n) is the moment resisting overturning due to the weight of the weight material 4 resisting pull-out in the wall member 3. Note that in this second term, the moment resisting overturning obtained by the weight of the weight material 4 is multiplied by the number n of columns resisting overturning. Additionally, the left side of the inequality (H(L+x)) is the overturning moment that occurs when horizontal force H acts, and the height at which the horizontal force acts is the sum of the height x of column base 2 and the height L from the top of column base 2 to where the horizontal force acts. The horizontal force is taken into account as the larger of earthquake force and wind pressure (see Table 1). The above height L must also take into account cases where weight is added to the ceiling of the building body 1a due to the installation of solar panels, etc., and the position at half the height of the building body 1a is not necessarily the center of gravity where the horizontal force acts. (Number 1) M=H(L+x) <W×(a / 2)+g×a×n Symbol: L Height from the top of column base 2 to the position where horizontal force H acts x Height from ground level to top of column base 2 W Weight of building body 1a a Distance between column bases 2 g. Weight of the weight material 4 resisting pull-out in the wall member 3 n Number of column bases 2 resisting pull-out = Number of column bases 2 resisting compression (for example, the two column bases marked with the symbol 2A in FIG. 2(B))

[0028] The height x from the ground surface to the top of the column base 2 should be 1500 mm or less and 200 mm or more (preferably 400 mm or more) in consideration of the use of container trucks and the bottom piping of the mobile building 1. As shown in Fig. 3, the weight of the weight material 4 on the upper side of the peripheral edge of the bottom plate 23 at an angle of 30 degrees or 45 degrees (see dotted lines in Fig. 3) from the vertical direction is the weight (g) of the weight material 4 that resists pulling out of the wall member 3. The angle of the soil lump cone fracture surface is set to 30 degrees or 45 degrees, and the angle is set to one of these two values.

[0029] Furthermore, the resistance to the shear force Q (=H) applied to the building main body 1a is the frictional resistance between the bottom plate 23 and the ground. If the weight of the weight material 4 in the wall member 3 is not taken into consideration, the frictional resistance is due only to the weight W of the building main body 1a, but if the weight material 4 is taken into consideration, the resistance can be achieved by a weight that takes into account both the weight W of the building main body 1a and the weight (g) of the weight material 4 (if the weight of the wall member 3 is assumed to be the same for all column bases 2, then W+g×2×n), and it is sufficient to satisfy the inequality condition in the following equation 2. Note that n is the number of column bases 2 resisting pull-out (2), so this is doubled to match the total number of column bases 2 (4). (Number 2) Q<μ(W+g×2×n) Symbol: μ Coefficient of static friction between the ground surface and the bottom plate 23

[0030] [Table 1]

[0031] In this embodiment, as shown in Fig. 4, a presser plate 25 that presses the weight material 4 downward is provided at a portion of the base 2 located above the weight material 4. This allows the compressive force acting on the base 2 due to the horizontal force acting on the building main body 1a to be transmitted to the weight material 4 by the presser plate 25 (see the dashed line in Fig. 4), so that the compressive force can be received by a short base portion on the upper side of the base 2, rather than by the entire length of the base 2.

[0032] 5, the column base 2 may have a protrusion 2a protruding toward the weight material 4. By having such a protrusion 2a, resistance to the pull-out force applied to the column base 2 due to the horizontal force applied to the building main body 1a can also be obtained by applying the weight of the weight material 4 to the protrusion 2a. In addition, the compressive force applied to the column base 2 due to the horizontal force applied to the building main body 1a can be received by the weight material 4 via the protrusion 2a.

[0033] As shown in Fig. 6, the wall member 3 may have a wall-side protrusion 3a that protrudes toward the weight material 4 in an area (above the dotted line in Fig. 6) on the inner wall side thereof that acts as a pull-out resistance. In this way, the wall-side protrusion 3a also acts as a resistance against the pull-out force applied to the column base 2.

[0034] As shown in Fig. 7, a crossover bottom plate 231 may be provided that spans between the bottom plates 23 of adjacent column bases 2, and the weight material 4 may also be present on the crossover bottom plate 231. In this way, resistance to the pull-out force applied to the column base 2 due to the horizontal force applied to the building main body 1a can be obtained by the weight of the weight material 4 being applied to the crossover bottom plate 231. Note that the bottom plate 23 may be made longer and used as the crossover bottom plate itself.

[0035] In the above embodiment, stones and the like are shown as the weight material 4, but this is not limited thereto. The wall member 3 is not essential. For example, as shown in Fig. 8(A) and Fig. 8(B), a semicircular concrete member 41 can be fitted from both sides of the column base 2 on the bottom plate 23 and made into a ring shape by fastening bolts and nuts 42, and this ring-shaped concrete member can be piled up to form the weight material 4. If the inner surface of the ring-shaped concrete member is brought into close contact with the outer periphery of the cylindrical column base 2, it is possible to obtain rigidity equivalent to that of a column base 2 with a large diameter. The shape is not limited to a ring shape, and may be a square ring shape, etc.

[0036] In addition, in the above embodiment, the column base 2 is attached to the fixed portion of the building main body 1a by the up and down movement of the loading platform 81, but this is not limited to the above. The building main body 1a may be lifted using a crane, the building main body 1a may be temporarily placed on a workbench, the column base 2 may be attached to the building main body 1a, and the building main body 1a may be lifted again using a crane and placed in the installation position.

[0037] Although the embodiment of the present invention has been described above with reference to the drawings, the present invention is not limited to the illustrated embodiment. Various modifications and variations can be made to the illustrated embodiment within the same scope as the present invention or within an equivalent scope. [Explanation of symbols]
