Description

  The present invention relates to a structural side plate that is attached to a juxtaposed laminated 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 ensured by a juxtaposed laminated structure formed by laminating a plurality of structural members in a horizontal direction in a hole formed by mining the ground while being laminated in the vertical direction. .

A structure side plate for preventing infiltration of earth and sand into the storage space may be attached to the outer peripheral surface of such a juxtaposed laminated structure (see, for example, Patent Document 1). The structure side plate of Patent Document 1 is a plate-like member provided with a plurality of reinforcing ribs on one surface, and a hook portion that is engaged with the juxtaposed laminated structure is provided at an upper end edge thereof. By engaging the hook portion with an engaging recess formed in the juxtaposed laminated structure, the structure side plate of Patent Document 1 is attached to the outer peripheral surface of the juxtaposed laminated structure.
Japanese Patent No. 3867960

  By the way, pressure (earth pressure) from earth and sand existing around the juxtaposed laminated structure acts on the side plate for structure attached to the outer peripheral surface of the juxtaposed laminated structure, and the side plate for structure has a juxtaposed laminated structure. It will be pressed to the body side. However, the structure side plate of Patent Document 1 is attached to the juxtaposed laminated structure with only the hook portion provided at the upper end, and is configured to be supported by the juxtaposed laminated structure only at the upper edge. When the earth pressure acts, there is a high possibility of causing problems such as deformation and breakage. In other words, this structure side plate is resistant to earth pressure on the upper edge side supported by the juxtaposed laminated structure, but is weaker against earth pressure on the lower edge side away from the upper edge. Yes. Therefore, when earth pressure acts, it is easy to displace so that it may enter the inside of a juxtaposed laminated structure toward the lower end side with the hook portion as an axis, and problems such as deformation of the plate surface and breakage of the hook portion may occur. Is expensive.

  This invention is made in view of such a conventional situation, and is providing the high intensity | strength side plate which can suppress generation | occurrence | production of a deformation | transformation, damage, etc., even if earth pressure acts. .

In order to achieve the above object, the structural side plate according to claim 1 and 2 , wherein a structural member including a base and a leg portion standing on the base is juxtaposed in a horizontal direction. A side plate for a structure that is attached to a juxtaposed laminated structure that secures a storage space in the water storage tank by stacking in a vertical direction, and the structure side engaging portion included in the juxtaposed laminated structure A side plate side engaging portion to be engaged is formed on the end portion side, and a bulging portion thicker than the end portion side in the stacking direction of the juxtaposed laminated structure is formed on the center side.

According to the above configuration , the bulging portion having a thickness larger than that of the end portion in the stacking direction of the juxtaposed laminated structure is formed on the central portion side, and the strength on the central portion side is higher than that of other portions. . Therefore, the earth pressure acting on the end portion not supported by the juxtaposed laminated structure is suitably absorbed by the bulging portion, and the entire structure side plate is not easily deformed. Therefore, according to this invention, the deformation | transformation, damage, etc. which arise when an earth pressure acts are suppressed.

In the structure for the side plate of claim 1, further wherein the bulging portion is proximate or abutting the legs the structural member has. According to the said structure , not only the edge part in which the side-plate side engaging part is formed but a contact part will be supported by the juxtaposed laminated structure. Thereby, when earth pressure acts, since the earth pressure can be suitably disperse | distributed to the whole side plate for structures, the intensity | strength with respect to earth pressure further improves.

In the structure for the side plate of claim 2, further on the side facing the juxtaposed stacked structure is regulated means formed to be inserted into the space between said legs, said regulating means Protrudes toward the juxtaposed laminated structure from the bulging portion . According to the above configuration , the lateral displacement of the structure side plate is suppressed by the contact between the restricting means and the leg portion. Further, when the restricting means is formed of a rib, the restricting means comes into contact with the leg portion on the surface. As a result, when the restricting means and the leg are in contact with each other, the load acting on the restricting means is dispersed, and the damage of the restricting means during the load action is suppressed.

Structure for the side plate according to claim 3, characterized in that in the invention of claim 1 or claim 2, side surfaces of the juxtaposed stacked structure not facing side is formed in the side view straight And

In general, a sheet having a water-impervious property, a water-permeable property, or the like is disposed between the juxtaposed laminated structure and a peripheral surface of a hole formed by mining the ground. According to the invention described in claim 3 , since the side surface that does not face the juxtaposed laminated structure, that is, the side surface on the sheet side is formed on a straight line when viewed from the side, even if the sheet is disposed, The problem that the sheet is pressed against the structural side plate by earth pressure and the sheet is torn is suppressed.

  According to the structure side plate of the present invention, even when pressure from earth and sand existing around the juxtaposed laminated structure is applied, the occurrence of deformation, breakage, or the like can be suppressed.

  In addition, in this embodiment, the front-view H-shaped part which bulges to the inner surface side of the side plate main body 31 including the part located inside the annular rib 33 is the bulging part 32. The bulging portion to be described corresponds to a portion of the bulging portion 32 in the present embodiment that is located outside the annular rib 33.

  Next, the side plate side engaging portion 40 provided at the upper and lower end portions of the side plate main body 31 will be described. As shown in FIG. 1, a pair of recesses 41 is formed at the upper and lower ends of the side plate body 31. Also in the recess 41, the edge rib 34 is erected along the shape of the recess 41. In the recess 41, a main engagement body 42 and a sub-engagement body 43 are erected upward or downward from an end on the inner surface side of the edge rib 34, and between the main engagement body 42 and the sub-engagement body 43. A reinforcing block 44 having a bottomed cylindrical shape opened inside the side plate body 31 is provided therebetween. In the present embodiment, a side plate side engaging portion 40 is configured by the main engaging body 42 and the sub engaging body 43. The side plate side engaging portions 40 provided at the upper and lower ends of the side plate main body 31 have the same shape. Here, the side plate side engaging portions 40 provided at the lower end of the side plate main body 31 will be described. .

  As shown in FIG. 1, the sub-engagement body 43 is a plate-like member that is formed to project downward from the end of the edge rib 34, and its tip projects downward from the lower end of the side plate body 31. . In addition, a slit is formed between the edge rib 34 located on the side of the recess 41 and the sub-engaging body 43 and between the sub-engaging body 43 and the reinforcing block 44.

  On the other hand, the main engagement body 42 is a plate-like member that is formed to project downward from the end portion of the edge rib 34, and its distal end side is bent in a substantially V shape toward the outer surface side of the side plate body 31. ing. This bending is performed at a position on the same line as the lower end of the side plate main body 31, and the main engaging body 42 protrudes below the lower end of the side plate main body 31 at the tip side from the bending position. As shown in FIG. 4, the main engagement body 42 protrudes below the sub-engagement body 43 with respect to the lower end of the side plate main body 31. Further, between the reinforcing block 44 and the main engagement body 42 and between the main engagement body 42 and the edge rib 34 located on the side of the recess 41, the same as that formed on both sides of the sub-engagement body 43. The slit is formed.

  As shown in FIGS. 1 and 3, the side plate body 31 and the bulging portion 32 are provided with a plurality of through-holes 38 that are open on the front and back surfaces, and these through-holes 38 function as a water flow path. A pair of protrusions 39 are erected on the inner surface side of the vertical bulge 32 a located in the annular rib 33. When the structure side plates 30 are stacked, these protrusions 39 are inserted into the outer surface side of the vertical bulges 32a of the structure side plates 30 located in the upper stage to suppress the collapse.

In addition, the side plate main body 31, the bulging part 32, various ribs, and the side plate side engaging part 40 which form the structure side plate 30 of this embodiment are all integrally formed.
Next, the attachment method with respect to the juxtaposed laminated structure 10 and the attachment state of the side plate 30 for structures of this embodiment are demonstrated based on FIGS. As shown in FIG. 3, the structure side plate 30 of the present embodiment is attached to the side surface of the juxtaposed laminated structure 10 in which the pair of structural members 11 are laminated so that the back surfaces of the bases are aligned. The size corresponds to one side surface formed between the pair of block bases 15. Therefore, in order to cover one side surface formed by the pair of structural members 11, two structural body side plates 30 are required.

  In order to attach the structure side plate 30 of the present embodiment to the juxtaposed laminated structure 10, the inner side surface is aligned with the juxtaposed laminated structure 10 side, and the annular rib 33 is positioned between the legs 13. To do. And the side plate 30 for structures is attached to the side surface of the juxtaposed laminated structure 10 by moving so that the side plate 30 for structural bodies may be pressed against the juxtaposed laminated structure 10 side (see FIG. 5). Specifically, as shown in FIG. 6, by pressing the structural side plate 30 against the side-by-side laminated structure 10 side, the side plate-side engaging portion 40 is elastically deformed to get over the standing frame 21 b and engage. It enters into the groove 21d. At this time, the main engagement body 42 is guided by the bent surface bent toward the outer surface side of the side plate main body 31, and smoothly moves into the engagement groove 21d.

  Next, a state where the structure side plate 30 of the present embodiment is attached to the juxtaposed laminated structure 10 will be described. As shown in FIG. 6, in the attached state, the main engagement body 42 abuts on the outer frame 21b at the tip, and the sub-engagement body 43 abuts on the inner frame 21a on the inner surface. As described above, the side plate side engaging portions 40 abut on the both side surfaces of the engaging groove 21d, so that the side plate side engaging portions 40 are stably positioned in the engaging groove 21d. Further, as shown in FIG. 5, the inclined surface 37 a abuts on the leg portion 13, and the annular rib 33 is inserted between the leg portions 13, and a part of the side surface abuts on the leg portion 13. Become.

  Further, both ends of the edge rib 34 and the lateral rib 35 of the structure side plate 30 of the present embodiment are formed so as to incline downward in the direction of the end with an inclination angle of 45 degrees. Therefore, even when the two structure side plates 30 are attached so as to be orthogonal to each other at the corners of the juxtaposed laminated structure 10, attachment failure due to the overlapping of the edge ribs 34 and the lateral ribs 35 may occur. It can be installed smoothly.

  When the earth pressure acts on the structure side plate 30 of the present embodiment attached to the juxtaposed laminated structure 10 in this manner, the structure side plate 30 is pressed to the juxtaposed laminated structure 10 side. At this time, the structure side plate 30 is supported by the juxtaposed laminated structure 10 by the sub-engaging body 43 positioned on the upper and lower end sides and the inclined surface 37a positioned in the center. That is, the pressure acting on the upper and lower ends of the structure side plate 30 is absorbed by the frame body 21, and the pressure acting on the center side is absorbed by the legs 13. A large load is suppressed. Moreover, when the stress which slides the structure side plate 30 to a horizontal direction acts, the movement to a horizontal direction is controlled because the annular rib 33 contact | abuts to the leg part 13. FIG.

Next, operational effects in the present embodiment will be described below.
(1) According to the present embodiment, the bulging portion 32 is formed such that the protruding height becomes higher toward the central portion side, and the strength of the central portion is higher than the other portions. Therefore, the earth pressure acting on the end portion side not supported by the juxtaposed laminated structure 10 is suitably absorbed by the bulging portion 32, and the entire structure side plate 30 is difficult to be deformed. Therefore, deformation or breakage of the structural side plate 30 that occurs when earth pressure acts is suppressed.

  (2) According to this embodiment, the inclined surface 37 a provided in the bulging portion 32 is in contact with the leg portion 13 of the structural member 11. When the earth pressure acts, the structure side plate 30 is supported not only by the standing frame 21 a but also by the leg portion 13. Therefore, the earth pressure acting on the structure side plate 30 can be dispersed throughout the structure side plate 30 and the earth pressure can be absorbed by the juxtaposed laminated structure 10. That is, since the earth pressure is supported by the entire juxtaposed laminated structure 10 and the load acting on the structure side plate 30 is suppressed, the structure side plate 30 is unlikely to be deformed or damaged.

  (3) In the present embodiment, an annular rib 33 is provided as a restricting means that is inserted into the space between the leg portions 13. Thereby, even if the stress which causes a lateral shift acts on the structure side plate 30, the lateral shift is suppressed by the contact between the annular rib 33 and the leg portion 13. Further, since the annular rib 33 is in surface contact with the leg portion 13, the load acting on the annular rib 33 at the time of contact is distributed throughout the annular rib 33. Therefore, damage to the annular rib 33 at the time of contact with the leg portion 13 is suppressed.

  The annular rib 33 also functions as a positioning means when attaching the structural side plate 30 to the juxtaposed laminated structure 10. By attaching the structure side plates 30 so that the annular ribs 33 are inserted into the spaces between the leg portions 13, the adjacent structure side plates 30 overlap each other, or a gap is formed between the adjacent structure side plates 30. Is suppressed. Therefore, it is possible to easily attach the structure side plate 30 to a predetermined position. Furthermore, the annular rib 33 is formed with a projecting height higher than the other ribs. Therefore, the strength of the central portion of the structure side plate 30 can be further increased.

  (4) The structure side plate 30 according to the present embodiment has the outer surface flush with it. Therefore, it is possible to suppress breakage such as tearing of the sheet that occurs when the sheet disposed around the juxtaposed laminated structure 10 and the structure side plate 30 rub against each other.

  (5) The main engagement body 42 of the present embodiment is formed to bend toward the outer surface side of the side plate body 31. Thereby, it becomes easy to engage with the engaging groove 21d and is difficult to be detached. Moreover, the structure side plate 30 attached to the juxtaposed laminated structure 10 may be periodically removed due to maintenance inspection or the like. In the present embodiment, since the sub-engagement body 43 is provided separately from the main engagement body 42, the sub-engagement body 43 is attached to the juxtaposed laminated structure 10 even if the main engagement body 42 is damaged during the removal. Is possible. Moreover, since the protrusion degree of the main engaging body 42 and the sub engaging body 43 is varied, the possibility that both engaging bodies are damaged at the same time is suppressed.

  (6) In the present embodiment, the flat surface 37 b is provided at the center of the bulging portion 32. Thereby, even if the fitting between the leg portions 13 is deviated, the structure side plate 30 of the present embodiment is easily and stably placed on the side surface of the juxtaposed laminated structure 10. Specifically, when the stack in the leg portion 13 is shifted in the juxtaposition direction of the juxtaposed laminate structure 10, the structural side plate 30 has one of the boundary lines between the inclined surface 37a and the flat surface 37b as an axis. It is possible to tilt. In particular, the structure side plate 30 can take more tilting positions because it can tilt about the two axes of the upper boundary line and the lower boundary line. Therefore, it becomes easy to fit in a stable position.

  (7) In the present embodiment, ribs are erected on the inner surface of the side plate main body 31, and ribs are erected on the outer surface of the side plate main body 31 in the recessed grooves formed corresponding to the bulging portions 32. In this way, the planar portion is formed to be uneven, and the ribs are erected on the opposite side to the uneven direction, so that the stress in the vertical direction acting on the structure side plate 30 can be suitably dispersed, and the structure The load resistance of the side plate 30 for use is improved. Moreover, according to this structure, generation | occurrence | production of the curvature in the side plate 30 for structures can also be suppressed.

  (8) Both ends of the edge rib 34 and the lateral rib 35 of the structural body side plate 30 of the present embodiment are formed so as to incline downward in the direction of the end with an inclination angle of 45 degrees. As a result, even when the two structure side plates 30 are attached so as to be orthogonal to each other at the corners of the juxtaposed laminated structure 10, an attachment failure occurs due to the overlapping of the edge ribs 34 and the lateral ribs 35. There is no. Therefore, it is not necessary to provide a side plate dedicated to the corner of the juxtaposed laminated structure 10, and the side surface of the juxtaposed laminated structure 10 can be covered with only one type of structural side plate 30. Further, the structure side plate 30 of the present embodiment can be attached to the juxtaposed laminated structure 10 even in a state where the top and bottom are inverted, similarly to the state before the inversion. Therefore, when attaching the structure side plate 30 to the juxtaposed laminated structure 10, it is not necessary to align in the vertical direction, and the structure side plate 30 can be smoothly attached to the juxtaposed laminated structure 10.

In addition, this embodiment can also be changed and embodied as follows.
In the present embodiment, the inclined surface 37a provided on the bulging portion 32 is formed so as to contact the leg portion 13 when attached to the juxtaposed laminated structure 10, but the inclined surface 37a and the leg portion 13 may not necessarily be in contact. For example, in the state where it is attached to the juxtaposed laminated structure 10, the inclined surface 37a is formed so as to ensure the clearance between the inclined surface 37a and the leg portion 13, and the earth pressure is pushed when the earth pressure acts. Accordingly, the inclined surface 37a and the leg portion 13 may be in contact with each other. Even in the case of such a configuration, the same effect as in the present embodiment can be obtained.

  The structure side plate 30 of the present embodiment is configured such that the inclined surface 37a of the bulging portion 32 comes into contact with the leg portion 13 by surface contact, but the bulging portion 32 with respect to the leg portion 13 is configured. The contact state is not limited to this. For example, you may comprise so that it may contact | abut by making line contact with respect to the leg part 13, and you may comprise so that it may contact | abut by making point contact.

  -In this embodiment, although the inclined surface 37a and the flat surface 37b were provided in the bulging part 32, the flat surface 37b does not need to be provided. For example, the inclined surface 37a may be provided up to the flat surface 37b, or the flat surface 37b may be formed on a curved surface. Further, as shown in FIG. 7A, the side plate main body 31 is formed flat, and the horizontal ribs 35 and the vertical ribs 36a are formed so that the projecting heights increase in order toward the center side. Thus, the bulging portion 32 may be formed by a rib. Moreover, as shown in FIG.7 (b), the rib which does not participate in the bulging part 32 other than the rib which forms the bulging part 32 is provided, and the protrusion height of each rib toward a center side is discontinuous. You may form so that it may become high.

  In the present embodiment, the bulging portion 32 includes two vertical bulging bodies 32a and a lateral bulging body 32b that is positioned substantially at the center of the vertical bulging body 32a and connects the vertical bulging bodies 32a. However, the bulging portion 32 may have any shape. For example, it may have a circular shape in front view or a polygonal shape.

  -Although the bulging part 32 of this embodiment was provided with the inclined surface 37a from which the protrusion height became high toward the center part side, this inclined surface 37a is a shape where protrusion height becomes high as the center part side.
