Description

  The present invention relates to a structural member for a water storage tank that constitutes a side-by-side stacked structure that secures a storage space of a water storage tank by being stacked in a vertical direction while being juxtaposed in a horizontal direction.

In areas where the population is concentrated, the ground is covered with buildings, asphalt pavement, etc., and the penetration of rainwater and the like into the basement is hindered. Under such circumstances, water damage is likely to occur due to the occurrence of torrential rain, etc., but as one of the measures to prevent such water damage, the installation of a water storage tank is effective. The water storage tank is a facility that temporarily stores a large amount of rainwater or the like in the ground or allows the stored rainwater or the like to permeate into the soil by flowing rainwater or the like into the tank. The storage space of such a water storage tank is secured by a plurality of structural members (see, for example, Patent Document 1). As shown in FIG. 7A, the structural member 11 of Patent Document 1 includes a base 12 and a plurality of leg portions 13 standing on the back surface of the base 12, and is formed by mining the ground. A plurality of structural members 11 are juxtaposed in the horizontal direction on the bottom surface of the hole and stacked in the vertical direction to secure a storage space. Specifically, the juxtaposed laminated structure is constructed by stacking the leg portions 13 so as to engage with the engaging portions 12 a provided in the surface of the base 12.
Japanese Patent No. 3867960

  By the way, it is difficult to form the bottom surface of the hole formed by mining the ground, that is, the installation surface T of the juxtaposed laminated structure completely flat, and the installation surface T has some unevenness. When such unevenness becomes excessive, it becomes difficult to construct a stable juxtaposed laminated structure, and the load resistance of the constructed juxtaposed laminated structure is reduced. For example, as shown in FIG. 7B, when the leg portion 13 of the structural member 11 is positioned on the concave portion present on the installation surface T, the one leg portion 13 floats with respect to the installation surface (FIG. 7 ( a solid line part in b), or a state in which the legs 13 are in a single contact (a chain line part in FIG. 7B). Therefore, the ground contact area between the installation surface T and the leg portion 13 is greatly reduced, and the installation state of the structural member 11 becomes unstable. In particular, the state in which the one leg portion 13 floats causes a bias in the load acting on the structural member 11. These points are the same when the leg portion 13 is located on the convex portion. If the structural members 11 are further stacked in the upper stage in such a state, an excessively large load is applied locally, causing distortion of the structural members 11 and displacement of the juxtaposed laminated structures. Reduces the load resistance. Further, the structural member 11 in which the leg portion 13 is located on the uneven surface is wobbled so as to change between the state in which the one leg portion 13 is lifted and the state in which both the leg portions 13 are in contact with each other. . Since this wobble is transmitted to the structural member 11 stacked on the upper stage, the stability of the entire juxtaposed laminated structure is significantly reduced.

  The present invention has been made in view of such a conventional situation, and the purpose thereof is to reduce the ground contact area between the installation surface T and the structural member 11 even when the installation is performed on the installation surface T where there is unevenness. It is providing the structural member for water storage tanks which can construct | assemble the juxtaposed laminated structure with load resistance and stability by suppressing.

Moreover, the structural member for the water storage tank according to claim 2 includes a base and a leg portion standing on the base, and stores the water by stacking a plurality of the base members in parallel. A structural member for a water storage tank that secures a storage space of the tank and constitutes a juxtaposed laminated structure, wherein the base is a plurality of planar square block bases having the leg portions via a connecting portion. The block base and the connecting portion are integrally formed, and the connecting portion is capable of bending or bending itself in the stacking direction in the juxtaposed laminated structure, and for each block base. Bending means for adjusting the height position is provided, and the base has a portion in which the block base is arranged in 2 × 2 in the vertical direction, and a through hole is formed at the intersection of the connecting portions in the portion. It is characterized by being.

According to invention of Claim 1 and 2 , the height position is adjusted for every block stand by changing the position of a block stand by bending or curving a connection part in the lamination direction in a juxtaposed laminated structure. It is possible. Thereby, even if unevenness exists on the installation surface, the position of each block base can be changed so that the ground contact area is increased according to the uneven shape. Therefore, there is no state where some block bases (or legs standing on the block base) are floated with respect to the installation surface, or all the block bases are not in a single contact state. The reduction of the contact area with the member is suppressed, and the bias of the load acting on the structural member is suppressed to the minimum. Therefore, even if it is a case where it installs on the installation surface in which an unevenness | corrugation exists, it contributes to provision of the juxtaposed laminated structure with load-bearing property and stability.
Moreover, according to invention of Claim 1, the bending direction of a connection part can be prescribed | regulated to a specific direction.

  According to the structural member for a water storage tank of the present invention, even when it is installed on an installation surface where unevenness exists, the reduction of the ground contact area between the installation surface and the structural member 11 is suppressed, and the load resistance and stability are reduced. It is possible to form a laminated structure with

  Hereinafter, an embodiment embodying the present embodiment will be described in detail with reference to FIGS. As shown in FIGS. 1 and 2, the structural member 11 for the water storage tank has a planar square base 12 and a leg portion 13 erected on the back surface of the base 12 integrally formed of a resin material. It is molded. This structural member 11 is used to construct a juxtaposed laminated structure in the ground. Specifically, after juxtaposing so that the surface of the structural member 11 is aligned with the bottom surface of the hole formed by excavating the ground, the structural members 11 are sequentially stacked so that the back surface and the surface of the base 12 are aligned. By doing so, a juxtaposed laminated structure is constructed. The juxtaposed laminated structure thus formed fulfills the function of securing the storage space of the water storage tank and supporting the ground on the storage space.

  As shown in FIGS. 1 and 2, the base 12 includes four block bases 15 </ b> A to 15 </ b> D having a substantially square shape, and the block bases 15 are integrally connected by a connecting portion 30. Since the block bases 15A to 15D have the same shape, only the block base 15A will be described here. The block base 15 </ b> A includes a square frame-shaped substrate 20. As shown in FIG. 1, the substrate 20 includes a frame body 21, and vertical ribs 22 and horizontal ribs 23 that extend vertically and horizontally inside the frame body 21.

  As shown in FIG. 3 (b), the frame body 21 is formed from an inner frame 21a, an outer frame 21b, and a middle frame 21c that connects the inner frame 21a and the end portion on the surface side of the outer frame 21b.

Similarly, the lateral rib 23 includes a first lateral rib 23a and a second lateral rib 23b, and both ends thereof are connected to the standing frame 21a. The end faces on the surface side of the vertical ribs 22 and the horizontal ribs 23 are formed so as to be flush with the surface of the frame body 21. The inside of the substrate 20 is divided into nine regions vertically and horizontally by vertical ribs 22 and horizontal ribs 23.

  As shown in FIG. 1 and FIG. 2, legs 13 are erected in the back surface direction in the regions located at the four corners among the divided regions in the substrate 20. The leg portion 13 has a square cylindrical shape that opens on the surface of the base 12 and is formed in a quadrangular pyramid shape that decreases in diameter from the base end toward the tip (see FIG. 3A). . The leg 13 is continuously formed integrally with the substrate 20 at the base end. Further, a fitting portion 14 having an uneven shape is formed at the tip of the leg portion 13. When the structural member 11 is laminated so that the back surface of the base 12 and the back surface of another base 12 are aligned, the fitting portion 14 is fitted with the fitting portion 14 formed on the other structural member 11. Combined. Such a fitting suppresses the problem that the structural member 11 that has finished being stacked is displaced.

  In the substrate 20, among the regions located between the leg portions 13, the region where the vertical ribs 22 and the standing frame 21a face each other is divided into two by the partitioning vertical ribs 22c, and the outer region is further partitioned. The horizontal rib 23c is divided into two in the vertical direction. In one of the regions, a fitting convex portion 25 is erected in the front surface direction, and in the other region, a fitting concave portion 26 is recessed in the rear surface direction (see FIG. 3A). . The fitting convex part 25 and the fitting concave part 26 are fitted when the structural member 11 is laminated so that the surface of the base 12 and the surface of another base 12 are matched. Such a fitting suppresses the problem that the structural member 11 that has finished being stacked is displaced.

  As shown in FIG. 2, the back surface side of the base 12 is covered over the entire surface, but the covered surface is formed integrally with the substrate 20 and the legs 13. Further, a plurality of through holes 24 opened on the front and back sides are provided in the covering surface, and these through holes 24 function as a water flow path and an air vent.

  Next, the connecting part 30 will be described. As described above, the connecting portion 30 is a portion that connects the block bases 15, and in the present embodiment, the four connecting portions 30 are arranged in a cross shape substantially at the center of the base 12 ( (See FIG. 1). The connecting portion 30 is a substantially rectangular plate-like member, and as shown in FIG. 3B, is joined to an upright frame 21b of the adjacent block base 15 on the side surface on the long side. In this embodiment, the connection part 30 is formed so that the thickness may become equal to the standing frame 21b. In addition, this connection part 30 is integrally formed with the standing frame 21b.

  The connecting portion 30 is formed so as to be divided into two equal parts with a bend line L (or bend line M) extending along the extending direction as an axis, and is formed to be bendable in the stacking direction in the juxtaposed laminated structure 10. Has been. Specifically, as shown in FIG. 1, a plurality of through-holes 31 penetrating the connecting part 30 on the front and back sides are arranged in parallel on the bending line L (or the bending line M) in the connecting part 30, and the cross section The substantially triangular slits 32 are formed along the bending lines L (or bending lines M) on the front and back surfaces of the connecting portion 30. Thereby, the rigidity on the bending line L (or bending line M) of the connecting part 30 is locally reduced, and the connecting part 30 can be bent with the bending line L (or bending line M) as an axis. Note that, at a portion where the bending line L and the bending line M intersect, a through hole 31 is formed around the intersection of the bending line L and the bending line M. In the present embodiment, the through hole 31 and the slit 32 constitute a bending means for making the connecting portion 30 bendable.

  As shown in FIG.1 and FIG.2, the base 12 of this embodiment arrange | positions block bases 15A-D in four corners, and arrange | positions so that the four connection parts 30 may make a cross shape as a whole between them. Yes. The block bases 15A to 15D are arranged so that the extending directions of the vertical ribs 22 and the horizontal ribs 23 are all the same direction.

  The base 12 is formed by integrally molding the block bases 15A to 15D and the connecting portion 30, and the bending operation of the connecting portion 30 is the bending operation of the entire base 12. As shown in FIGS. 4A and 4B, the connecting portion 30 is bent upward in the stacking direction in the juxtaposed laminated structure 10, that is, the back surfaces of the connecting portions 30 are brought close to each other with the bending line L as an axis. Then, the base 12 is bent so that the ends of the leg 13 standing on the block base 15A and the leg 13 standing on the block base 15B are brought close to each other with the bending line L as an axis (FIG. 4 ( a two-dot chain line portion of a) and (b)). When the connecting portion 30 is bent downward in the stacking direction in the juxtaposed laminated structure 10, that is, the back surfaces of the connecting portions 30 are separated from each other with the bending line L as an axis, the base 12 has the bending line L as an axis. As shown in FIG. 4A and FIG. 4B are bent so as to be spaced apart from each other. Such a bending action of the base 12 is not limited to the block bases 15A-B, and has the same bending action in all of the adjacent block bases 15A to 15D.

  Next, the laminated state of the structural member 11 of this embodiment will be described. In the present embodiment, after the structural members 11 are juxtaposed in the horizontal direction so that the surface of the structural member 11 is aligned with the installation surface T, the structural members 11 are aligned with the back surfaces of the base 12 and the surfaces thereof. A juxtaposed laminated structure is constructed by sequentially stacking. Specifically, the fitting convex portion 25 and the fitting concave portion 26 are fitted together so that the surfaces of the base 12 are overlapped with each other, and the fitting portions 14 are fitted so that the tips of the leg portions 13 are brought into contact with each other. Fit them together. At this time, the problem that the stacked structural members 11 are displaced is suppressed by the fitting between the fitting convex portion 25 and the fitting concave portion 26 and the fitting between the fitting portions 14.

  As described above, the installation surface T on which the structural members 11 are juxtaposed is not formed flat, and irregularities may exist on the installation surface T. For example, as shown in FIG. 5, when the structural member 11 is installed on the concave portion existing on the installation surface T, the block base 15 </ b> A is in a floating state with respect to the installation surface T in the conventional configuration (the chain line in FIG. 5). portion). On the other hand, in the structural member 11 of the present embodiment, from this state, the ends of the leg portion 13 erected on the block base 15A and the leg portion 13 erected on the block base 15B with the bend line L as an axis. By bending the connecting portion 30 so as to separate the block table 15A and changing the position of the block table 15A downward, the block table 15A comes into contact with the installation surface T (the solid line portion in FIG. 5). At this time, the position of the adjacent block table 15B is not changed with the position change of the block table 15A, and the installation state of the installation surface T and the entire substrate 20 of the block table 15B is maintained as normal. .

  On the other hand, as shown in FIG. 6, when the structural member 11 is installed on the convex portion existing on the installation surface T, in the conventional configuration, both the block bases 15A and 15B are in a single-contact state with respect to the installation surface T (FIG. The chain line part). On the other hand, in the structural member 11 of the present embodiment, the tips of the leg portion 13 standing on the block base 15A and the leg portion 13 standing on the block base 15B with the bend line L as an axis from this state. The connecting portion 30 is bent so as to be close, and the position of the periphery of the connecting portion 30 is changed downward, so that a normal installation state is formed between the block base 15B and the installation surface T (FIG. 6). Solid line part).

  At this time, the height position of the leg portion 13 erected on each block base 15 is also changed as the connecting portion 30 is bent in accordance with the shape of the installation surface T. That is, in the case shown in FIG. 5, the leg portion 13 of the block base 15 </ b> A is repositioned downward while the tip thereof is inclined in a direction away from the tip of the leg portion 13 of the block base 15 </ b> B. Further, in the case shown in FIG. 6, in particular, the leg portion 13 of the block base 15A and the leg portion 13 on the connecting portion 30 side of the block base 15B are repositioned downward while being inclined in the direction in which their tips approach each other. The However, as shown in FIG. 5 and FIG. 6, the connecting portion 30 of the structural member 11 stacked on the upper stage is bent in the same manner as described above, so that the fitting portion 14 formed between the leg portions 13 is interposed between the fitting portions 14. A contact relationship is formed. This point is not limited to the case of stacking so that the surfaces of the bases 12 are aligned with each other, and the same applies to the case of stacking so that the back surfaces of the bases 12 are aligned with each other. A contact relationship is formed between the fitting convex portion 25 and the fitting concave portion 26.

  In this way, a new structure member 11 is laminated on the structure member 11 and the operation of juxtaposing the structure member 11 in the horizontal direction is repeated, whereby a juxtaposed laminated structure is constructed. And the installation of a water storage tank is completed by performing leveling etc. on the water storage tank which installed the juxtaposed laminated structure.

Next, operational effects in the present embodiment will be described below.
(1) In this embodiment, the base 12 is formed by integrally molding the four block bases 15 having the leg portions 13 and the connecting portions 30 for connecting the block bases 15. Further, by providing the connecting portion 30 with the through hole 31 and the slit 32 which are bending means, the stacking direction in the juxtaposed laminated structure 10, that is, the ends of the leg portions 13 standing on the adjacent block base 15 are brought close to each other or The connecting portion 30 can be bent in the direction of separation. Accordingly, the height position of each block base 15 can be adjusted by bending the connecting portion 30 to change the position of the block base 15. Thereby, even if unevenness exists on the installation surface T, the position of each block base 15 can be changed so that the ground contact area is increased in accordance with the uneven shape. Therefore, a part of the block bases 15 is not lifted with respect to the installation surface T, or all the block bases 15 are not in a single contact state, and the ground contact area between the installation surface T and the structural member 11 is reduced. It is suppressed. Therefore, the bias of the load acting on the structural member 11 is suppressed to the minimum, and the occurrence of wobble due to the uneven portion of the installation surface T is suppressed.

  Further, as the lowermost structural member 11 is bent and deformed according to the shape of the installation surface T, the height position of the fitting portion 14 provided in the structural member 11 is also changed. The structural member 11 stacked on the upper stage is similarly bent and deformed to form a contact relationship between the upper and lower structural members 11. Therefore, even if the lowermost structural member 11 is bent and deformed in accordance with the shape of the installation surface T, occurrence of poor fitting with the structural member 11 stacked in the upper stage is suppressed.

Therefore, according to the structural member 11 of the present embodiment, it is possible to construct a juxtaposed laminated structure having load resistance and stability even when it is installed on the installation surface T where there is unevenness.

Thereby, the rigidity of the site | part on the bending line L (or bending line M) of the connection part 30 becomes small locally, and it becomes easy to bend the connection part 30 on the bending line L (or bending line M). Become. Moreover, since the slit 32 is formed in each of the surface and the back surface of the connection part 30, it is easy to bend in both directions of the direction which makes the surfaces of the connection part 30 approach, and the direction which separates.

  (3) In this embodiment, on the bending line L (or bending line M) in the connection part 30, the some through-hole 31 which penetrates the connection part 30 to the front and back as a bending means is arranged in parallel. Thereby, the rigidity of the site | part on the bending line L (or bending line M) of the connection part 30 becomes small locally, and it becomes easy to bend the connection part 30 on the bending line L (or bending line M). Become. Moreover, since the through-hole 31 has penetrated the connection part 30 in the front and back, it can be functioned also as a flow path and air vent of water.

In addition, this embodiment can also be changed and embodied as follows.
-In this embodiment, although the connection part 30 was formed so that bending was possible in the lamination direction in the juxtaposed laminated structure, the connection part 30 may be formed so that it can be bent in the same lamination direction. Even when formed in this way, the same effects as the structural member 11 of the present embodiment can be obtained.

  -Although the structure member 11 of this embodiment employ | adopted the structure laminated | stacked so that the back surfaces and surfaces of the base 12 may match, it laminates | stacks so that the surface side and back surface side of the base 12 may match.
