Description

Frame for a housing stand, housing stand, construction method thereof, housing system, and construction method thereof

[0001] The present invention relates to a frame for a housing stand, a housing stand, a construction method thereof, a housing system, and a construction method thereof.

[0002] When installing a housing such as a container on the ground surface, a container stand that serves as a mounting table for the container is often used (see, for example, Patent Documents 1 and 2).

[0003] Japanese Patent Application Laid-Open No. 2019-64731, Japanese Patent Application Laid-Open No. 2006-257680

[0004] However, the conventionally used container stands have the following problems (see Patent Documents 1 and 2). - The structure may not be simple. Especially in the case of a container stand that supports a heavy container (for example, a container with built-in equipment such as a storage battery), it has to be a structure with sufficient strength, which leads to an increase in weight and makes it difficult to reduce costs. - Although container stands using concrete foundations are also used, such container stands tend to have a long construction period until installation, such as requiring time for the curing of concrete. - In the case of a container stand using a concrete foundation, it is not easy to restore the original state when removed after the service life has passed. Also, the work for restoring the original state may affect the surrounding environment. - Concrete foundations have problems such as it being difficult to secure a wide passage because the horizontal projected area of the foundation part is larger than the horizontal projected area of the container, and the site area cannot be effectively utilized.

[0005] Therefore, an object of the present invention is to provide a frame for a housing stand, a housing stand, a construction method thereof, a housing system, and a construction method thereof that have a simple structure, are low-cost, take less time than a concrete foundation, are easy to restore the original state when removed after the service life has passed, are environmentally friendly, and can effectively utilize the site area.

[0006] One aspect of the present invention is a frame for a housing stand that constitutes a stand on which a housing is placed, the frame for a housing stand having: four or more pile caps; and a horizontal beam that connects adjacent pile caps.

[0007] Normally, it is difficult to drive piles according to the design, and horizontal and vertical displacements and tilts may occur. In this respect, the above-mentioned enclosure frame equipped with a pile head cap that allows a gap to be created between the pile head and the frame allows for flexible construction without being affected by horizontal and vertical displacements or tilts. This effect is more pronounced as the number of piles increases. Moreover, this enclosure frame requires a shorter construction period compared to a concrete foundation, and restoration to the original state after removal following the expiration of its service life is relatively easy, resulting in less impact on the surrounding environment and allowing for effective use of the site area.

[0008] In the above-described frame for the enclosure, either or both of the pile head cap and the horizontal beam may be provided with an enclosure mounting portion that engages with the enclosure.

[0009] An enclosure frame according to one aspect of the present invention is an enclosure frame comprising the above-described enclosure frame and a pile driven into the ground with the pile head inserted into a pile head cap, wherein a fluid solidified material is filled between the pile head cap and the pile head of the pile.

[0010] An enclosure system according to one aspect of the present invention is an enclosure system that includes an enclosure stand as described above and an enclosure placed on the enclosure stand.

[0011] In the enclosure system described above, an intermediary frame may be interposed between the enclosure stand and the enclosure.

[0012] Another embodiment of the present invention is a housing system comprising four or more piles driven into the ground, a pile head cap into which the pile heads of the piles are inserted and a fluid solidified material is filled in the gap between the pile head and the cap, and a housing placed on the pile head cap.

[0013] In the enclosure system described above, some of the adjacent pile head caps may be connected to each other by a horizontal beam.

[0014] A method for constructing a frame for an enclosure according to one aspect of the present invention includes the steps of: driving four or more piles into the ground; placing a frame for an enclosure, which is manufactured in advance and has the same number and arrangement of pile head caps as the number and arrangement of piles, on top of the pile heads of the piles so as to be inserted into the corresponding pile head caps; and filling the space between the pile head caps and the pile heads of the piles with a fluid solidified material and allowing it to solidify.

[0015] A construction method for a housing system according to another aspect of the present invention includes the steps of: driving four or more piles into the ground; placing a housing, which is manufactured in advance and equipped with the same number and arrangement of pile head caps as the number and arrangement of piles, such that the pile heads of the piles are inserted into the corresponding pile head caps; and filling the space between the pile head caps and the pile heads of the piles with a fluid solidified material and allowing it to solidify.

[0016] According to the present invention, it is possible to provide a frame for a housing support structure, a housing support structure and its construction method, and a housing system and its construction method, which are simple in structure, low in cost, require less construction time compared to concrete foundations, are easy to restore to their original state when removed after the service life has expired, are environmentally friendly, and allow for effective use of site area.

[0018] Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.

[0019] A container system (enclosure system) 1 according to one aspect of the present invention is a system comprising a container frame (enclosure frame) 10 and a container (enclosure) 20 placed on the container frame. The container 20 to be placed in this embodiment is a container that tends to be particularly heavy, for example, by incorporating equipment such as a storage battery. The container frame 10 in this embodiment includes a container frame 100 and piles 200, and is integrated with the piles 200 driven into the ground G, and is configured as a structure with sufficient strength to support such a container 20 (see Figure 1, etc.).

[0020] The container support frame 100 is configured as a frame that constitutes a support structure on which the container 20 is placed. In this embodiment, the container support frame 100 is composed of a pile head cap 102 and a horizontal beam 104 (see Figure 4, etc.).

[0021] The pile head cap 102 is a member formed to a size that allows at least a portion of the pile head 202 of the pile 200 to be inserted, and to allow a gap to be created between the inserted pile head 202 and the member. In this embodiment, the pile head cap 102 is a cylindrical member similar to the pile head 202 of the pile 200, but its shape is not particularly limited. The size of the pile head cap 102 is preferable if it is large enough to reduce the gap between it and the pile head 202, as this reduces the amount of fluid solidified body 300 that needs to be filled into the gap. However, if there is not a sufficient margin in the gap, it may interfere with the pile head cap 102 when placing it over the pile head 202, potentially hindering construction, and construction errors of the pile 200 may not be absorbed. Therefore, it is preferable to have a size that is appropriate to take these factors into account. Furthermore, in this embodiment, a pile head cap 102 with a lid on top and an open bottom is used (see Figure 3, etc.), but this is merely one example, and although not specifically shown, other shapes such as one in which a part of the lid on the top is open can also be used. Also, the number and arrangement of the pile head caps 102 are not particularly limited, but it is preferable to use a number and arrangement that is suitable for evenly and stably supporting the heavy container 20. Examples of such a number and arrangement include a configuration in which four pile head caps 102 are placed at the four corners to match the shape of the container 20 (see Figure 4), or a configuration in which another pile head cap 102 is placed between the four pile head caps 102 placed at the corners, for a total of six (see Figure 1).

[0022] The horizontal beams 104 are members that connect the side surfaces 102s of adjacent pile head caps 102. By connecting the side surfaces 102s of the pile head caps 102 with these horizontal beams 104, a container support frame 100 of a predetermined shape is formed (see Figures 2 and 3, etc.). There are various predetermined shapes, but as described above, if four pile head caps 102 are placed at the four corners to match the shape of the container 20, a roughly rectangular container support frame 100 is formed by connecting them with four horizontal beams 104 (see Figure 4). Alternatively, if another pile head cap 102 is placed between the four pile head caps 102 placed at the corners, for a total of six, a roughly rectangular container support frame 100 is formed by connecting them with seven horizontal beams 104 (see Figure 1). I-beams and H-beams can be used as horizontal beams 104, but there are no particular limitations on their specific shape or material. Furthermore, the ends of the horizontal beam 104 are joined to each other by welding directly to the side surface 102s of the pile head cap 102, or to the bracket portion 103b (see Figure 3, etc.).

[0023] The piles 200 are driven into the ground G at the construction site where the containers 20 will be placed, and constitute the foundation of the container frame 10 (see Figures 1 and 2). In this embodiment, steel pipe piles with wing-shaped portions 204 near the downward-facing ends are used as the piles 200 (see Figures 6A and 6B), but this is just one example, and other types of piles may be used.

[0024] A fluid solidified material 300 is filled into the gap between the pile head 202 of the pile 200 and the pile head cap 102 placed over the pile head 202 (see Figure 3). The fluid solidified material 300 is made of a hardening material such as concrete or mortar, and solidifies after being filled into the gap of the pile head cap 102, integrating the pile head 202 of the pile 200 with the pile head cap 102.

[0025] An example of a construction method for the container support frame 100, container support 10, or container system 1 including these, as described above, is explained below.

[0026] First, the container support frame 100 is pre-assembled. During assembly, the number and arrangement of the pile head caps 102 are the same as the number and arrangement of the piles 200 to be driven, and the sides 102s of these pile head caps 102 are joined together (see Figure 4). The container support frame 100 may be pre-assembled at the construction site of the container system 1, or it may be done in a designated factory. Alternatively, the container support frame 100 may be pre-assembled by placing the pile head caps 102 on the driven piles 200, then installing the horizontal beams 104 and filling the pile head caps 102 with hardening material, or the pile head caps 102 may be placed on the piles 200 and positioned, then the hardening material may be filled first, and then the horizontal beams 104 may be installed.

[0027] Now, at the construction site of the container system 1, first, a predetermined number (but four or more) piles 200 are driven into the ground G at predetermined locations. Then, the container support frame 100 is installed so that the pile head 202 of each pile 200 is inserted into the corresponding pile head cap 102. After that, the fluid solidification body 300 is filled between the pile head cap 102 and the pile head 202 of the pile 200 and allowed to solidify. The container system 1 is then completed by placing the containers 20 at predetermined positions on the completed container support frame 10 (see Figure 7, etc.).

[0028] When installing a container frame or a container system including the same, it is difficult to drive the piles according to the design, and horizontal and vertical displacements and inclinations usually occur. In this regard, the container frame 100, container frame 10, or container system 1 including the same of this embodiment, as described above, is equipped with a pile head cap 102 that can create a gap between itself and the pile head 202, making it possible to construct flexibly without being affected by horizontal and vertical displacements or inclinations. In particular, even if the horizontal and vertical displacements and inclinations of four or more piles 200 differ from each other, a container frame 10 with a horizontal alignment can be easily constructed by simply adjusting the position and inclination of the entire container frame 100 while ensuring that the pile head 202 of each pile 200 is inserted into the corresponding pile head cap 102, without performing special construction to correct them (re-installing the piles, inserting filler plates, etc.), and without requiring adjustment of the position and inclination of each pile head cap 102 included in the container frame 100 or a special mechanism for such adjustment.

[0029] Thus, according to the container support frame 100, container support 10, or container system 1 including these of this embodiment, the construction period is shorter compared to a concrete foundation, and it is relatively easy to restore the original state when removing the structure after the service life has expired, thus minimizing the impact on the surrounding environment and allowing for effective use of the site area.

[0030] The above-described embodiment is merely one example of a preferred implementation of the present invention, and is not limited thereto. Various modifications are possible without departing from the spirit of the invention. For example, in the container frame 100 with the above-described configuration, a container mounting portion (housing mounting portion) 106 that engages with the container 20 may be provided on either the pile head cap 102 or the horizontal beam 104, or both (see Figure 5). The container mounting portion 106 is composed of a pin or the like that restricts the horizontal movement of the container 20. In particular, by fixing the container 20 with the container mounting portion 106 provided on the horizontal beam 104, the horizontal movement of the installed container 20 can be effectively suppressed.

[0031] Furthermore, in the above-described embodiment, the container 20 was placed directly on the container stand 10 (see Figures 1, 2, 7, etc.), but another member may be interposed between the container stand 10 and the container 20 (see Figure 8). Examples of such an interposed member include a plurality of frame-shaped members (referred to as an interposing frame in this specification and denoted by reference numeral 30) (see Figure 8). The interposing frame 30 consists of a plurality of frames longer than the total length of the horizontal beam 104. By employing such an interposing frame 30, the size of the container 20 that can be placed on the container stand 10 can be flexibly selected. While a beam-shaped interposing frame 30 is shown here (see Figure 8), this is merely an example, and other types of interposing frames, such as a plate-shaped interposing frame 30, may also be employed.

[0032] Up to this point, preferred examples of the container frame 100, container frame 10, or container system 1 including these according to this embodiment have been described. However, in other embodiments, it is possible to have a structure in which some or all of the horizontal beams are omitted. Specifically, it is possible to have a container system 1 that includes four or more piles 200 driven into the ground G, pile head caps 102 into which the pile heads 202 of the piles 200 are inserted and the gap between the pile heads 202 and the caps is filled with a fluid solidified body 300, and a container 20 placed on the pile head caps 102 (see Figure 9 for a container system 1 in which all horizontal beams are omitted). This can be said to be a structure that makes construction easier by eliminating the need for some or all of the horizontal beams by utilizing the in-plane rigidity of the floor of the container 20 itself.

[0033] Furthermore, when constructing such a container system 1, one example of the process is to pre-manufacture a container 20 equipped with the same number and arrangement of pile head caps 102 as the number and arrangement of piles 200, then, after driving four or more piles 200 into the ground G, place the container 20 so that the pile heads 202 of the piles 200 are inserted into the corresponding pile head caps 102, and then fill the space between the pile head caps 102 and the pile heads 202 of the piles 200 with a fluid solidified material 300 and allow it to solidify.

[0034] In the embodiments described so far, one example of an enclosure is a container 20, and an example of equipment built into the container 20 is a storage battery. However, equipment other than a storage battery (such as communication equipment or substation equipment) may be built into the container 20. Furthermore, the enclosure does not have to be a container 20; it may be a warehouse, a house (including temporary housing), a shelter, etc.

[0035] However, if a suitable enclosure is selected, such as a container 20 with in-plane floor rigidity, the four or more pile head caps 102 will be more firmly bound together, which has the advantage of eliminating the need to use braces to bind the pile head caps 102 that are not directly bound by the horizontal beam 104. Eliminating the need for braces between the pile head caps 102 reduces material costs, shortens construction time, and makes it relatively easy to restore the original condition when the structure is removed after its service life has expired.

[0036] Furthermore, in the above-described embodiment, the case in which the side surfaces 102s of adjacent pile head caps 102 are connected by a horizontal beam 104 was explained, but this is also merely one preferred example. The horizontal beam 104 may also be attached and connected to a location other than the side surfaces 102s of the pile head cap 102, for example, to the top surface 102t of the pile head cap 102 (see Figure 11).

[0037] Furthermore, when a container 20 having surface rigidity as described above is placed as the enclosure, it may be possible to omit not only the braces but also the horizontal beams 104 (see Figure 9). Incidentally, in addition to omitting all of the horizontal beams 104, it is also possible to omit only a portion of the horizontal beams 104 (see Figure 10). In the latter case, some of the adjacent pile head caps 102 are connected to each other by the horizontal beams 104 (see Figure 10).

[0038] Furthermore, in a configuration where some pile head caps 102 are connected by horizontal beams 104 (see Figure 10), the intermediate portions of two opposing horizontal beams 104 (meaning a position closer to the center excluding the ends of the horizontal beams 104, and not necessarily the exact midpoint) may be connected by another one or more horizontal beams 105 (Figure 12). With this configuration, the position of the horizontal beams can be changed according to the location where the reaction force acts, as the position differs depending on the specifications of the enclosure (weight, shape, center of gravity, etc.). Also, if the enclosure is electrical equipment such as a battery storage facility, substation, or communication equipment, excavation work will be required when burying power cables, communication cables, etc., so the position of the horizontal beams can be adjusted to facilitate the work.

[0039] The present invention is particularly suitable for application to a frame for a container rack, a container rack and its construction method, and a container system and its construction method.
