Description

  The present invention relates to a cylindrical body for a storage and permeation tank (hereinafter, also referred to as a cylindrical body as appropriate) used in a tank for storing and permeating rainwater, for example, and in particular, coupling of side plate members constituting the cylindrical body The present invention relates to a structure, a tubular body for a storage permeation tank having the joint structure, a box body for a storage permeation tank, and a method for joining side plate members constituting the tubular body for a storage permeation tank.

  Conventionally, a storage and penetration tank for rainwater has been proposed in which rainwater is temporarily stored, and the stored rainwater is gently infiltrated into the ground to be drained. The storage permeation tank is generally configured by laying a water-permeable sheet in a recess formed by excavation and stacking a plurality of storage permeation tank cylinders thereon.

  Moreover, although the said cylindrical body was a product made from concrete, the thing made from resin is proposed from the ease of construction and conveyance in recent years (for example, patent documents 1, 2). In such a configuration, there are some which form a cylindrical body by joining a plurality of resin side plate members at a construction site or the like. Further, a drainage basin having a similar configuration has already been proposed (for example, Patent Document 3).

  Specifically, in Patent Documents 1 to 3 described above, in order to join the side plate members, a concave portion formed over the entire length on the side edge portion of one side plate portion and a full length formed on the side edge portion of the other side plate portion. A configuration is disclosed in which the protruding portion is engaged while sliding.

Japanese Patent No. 3556776 JP 2006-214103 A JP-A-8-291551

  However, as in the conventional configuration described above, when the concave portion and the convex portion are provided over the entire length of the side plate member, deflection and distortion occur in the side plate member when assembling the cylindrical body, and the concave and convex portions are not easily fitted, There arises a problem that it takes time to join the side plate members. In addition, as a work space necessary for the joining work, a space corresponding to the length of at least two side plate members is required, which is a very inconvenient configuration at a construction site where work is performed in a limited space.

  Therefore, the present invention provides a coupling structure for side plate members that can form a cylindrical body for a storage and permeation tank that can be easily combined with side plates and does not require a large working space, and a storage and permeation tank that has the coupling structure. It aims at providing the coupling | bonding method of the side plate members which comprise the cylindrical body for this, and this cylindrical body for storage permeation tanks.

The present invention relates to a coupling structure of side plate members in a cylindrical body for a storage and permeation tank in which a plurality of side plate members are coupled to each other, and includes a movement restricting portion and a slide member on a side edge portion of one side plate member. it is 1 or more respectively arranged engaging portion along the side edges of the side edge, the position corresponding to the movement restricting portion a side edge of the other side plate member the movement restricting portion is distribution it is set, said positions corresponding to the sliding engagement portion becomes disposed that the slide engaging section, the movement limiting portion and the object movement restricting portion, the movement restricting portion and該被movement restricting portion In the first direction perpendicular to the axis of the cylindrical body for the storage and permeation tank, wherein the side plate members are movable relative to each other only in a predetermined direction. The movement restricting portion and the movement restricting portion are engaged with each other along the The restricting portion and the movement restricting portion have an engagement mechanism that is relatively movable only in a second direction orthogonal to the first direction in an engaged state, and further, the movement restricting portion and the moved portion The side plate members move relative to each other along the second direction while the regulating portion is engaged, and the side plate members are engaged with each other with the slide engagement portion and the slide engagement portion engaged with each other. It is the coupling | bonding structure of the side-plate members in the cylindrical body for storage permeation tanks characterized by being couple | bonded.

In such a configuration, first, the side plate members placed at positions where the coupling sites face each other approach each other, whereby a state in which the movement restricting portion and the movement restricting portion are engaged with each other is obtained. At this time, the side plate members are allowed to move relative to each other only in a predetermined direction, and the side plate members are loosely fitted to each other and are temporarily fixed. Since this temporary fixing operation merely brings the connecting portions of the two side plate members to be combined close to each other, a work space having a length corresponding to two side plate members as in the prior art is unnecessary. Further, the side plate members are relatively moved in the temporarily fixed state, and the slide engagement portion and the slide engagement portion are engaged with each other. This operation is temporarily stopped so that the movement restricting portion and the movement restricting portion are engaged in advance so that the side plate members are not easily separated from each other, and the deflection of each side plate member is suppressed. This is an extremely simple task. Furthermore, in such a configuration, in order to obtain a state in which the movement restricting portion and the movement restricting portion are engaged with each other, first, the side plate members placed at positions where the coupling sites face each other are placed in the cylindrical shape. It moves relatively along a first direction perpendicular to the body axis. When the movement restricting portion and the movement restricting portion are engaged with each other, the side plate members are allowed to move only in a second direction orthogonal to the first direction, and are temporarily fixed. It becomes. Since the work for obtaining the temporarily fixed state is merely to bring the joining portions of the two side plate members to be joined closer to each other along the first direction, the length of the two side plate members as in the prior art is reduced. There is no need for a working space.

  Further, the side plate members are relatively moved along the second direction in the temporarily fixed state, whereby the slide engagement portion and the slide engagement portion are engaged with each other. This operation is temporarily stopped so that the movement restricting portion and the movement restricting portion are engaged in advance so that the side plate members are not easily separated from each other, and the deflection of each side plate member is suppressed. This is an extremely simple task. In particular, it is not necessary to move the side plate members relative to each other over the entire length as in the conventional configuration, and it is only necessary to slide the slide engagement portion and the slide engagement portion to a position where they are engaged with each other. Will improve dramatically. In addition, since it is not necessary to form the slide engaging portion over the entire length of the side plate member, it is not necessary to set a large clearance (so-called play or gap) in consideration of the deflection or distortion of the side plate member, and the coupling can be performed with higher accuracy. It can be a structure. Furthermore, the coupling structure according to the present invention includes a movement restricting portion and a movement restricting portion that are engaged by relative movement along the first direction, and a slide engagement that is engaged by relative movement along the second direction. Since the side plate members are coupled to each other by the engaging means that engages based on two different directions in this manner, the side plate members are unlikely to come off.

  In the above configuration, the movement restricting portion of the one side plate member and the movement restricting portion of the other side plate member are both formed from a plate piece shape protruding from the side edge portion of each side plate member. When the movement restricting portion and the movement restricting portion are engaged, the movement restricting portion and the movement restricting portion are overlapped with each other, and the relatively slidable direction is the second direction. The sliding engagement portion of the one side plate member is disposed at the neck portion protruding from the side edge portion of the side plate member, and the wide head is disposed at the tip of the neck portion and wider than the neck portion. The sliding engagement portion of the other side plate member is a hole formed in a side edge portion of the side plate member, and the hole portion is narrower than the wide head. A narrow hole through which the neck can pass, and the narrow hole is continuous with the narrow hole and wider than the narrow hole. A wide hole portion through which the wide head can be inserted, and when the movement restricting portion and the movement restricting portion are engaged, the wide head of the slide engaging portion is the slide target The neck portion of the slide engagement portion is inserted into the wide hole portion of the hole portion of the engagement portion, and the side plate members move relative to each other along the second direction, so that the neck portion of the slide engagement portion becomes the hole of the slide engagement portion. The slide engagement portion and the slide engagement portion are locked in the first direction by positioning the slide engagement portion and the slide engagement portion. A configuration in which the two are engaged with each other is desirable.

  By adopting such a configuration, it is possible to configure the engagement mechanism relating to the movement restricting portion and the movement restricting portion with a simple structure. Further, with the movement restricting portion and the movement restricting portion engaged with each other, the neck portion of the slide engaging portion is positioned in the narrow hole portion of the slide engaging portion, and the slide engaging portion The sliding engagement portion can be engaged. Therefore, rattling between the side plate portions when the slide engagement portion and the slide engagement portion are engaged is suppressed. For example, between the lateral width of the neck portion and the lateral width of the narrow hole portion. The so-called play interval can be made as small as possible, and the assembly accuracy can be greatly improved without impairing workability. In addition, the operation of moving the side plate members relative to each other along the second direction only needs to slide the side plate members by the length of the wide head, so that the work space can be reduced compared to the conventional case. .

  In the relative movement of the side plate members along the second direction, it is desirable that which side plate member is moved or which side plate member is moved can be freely selected depending on the situation of the work site. . Accordingly, it is desirable that the wide hole portion of the hole portion of the sliding engagement portion is formed on both sides of the narrow hole portion along the second direction.

  In this configuration, when the movement restricting portion and the movement restricting portion are brought into the engaged state, any one of the wide hole portions on both sides of the narrow hole portion is appropriately selected and the slide is performed. The wide heads of the engaging portions can be inserted, and the side plate members can be relatively moved along the second direction. For this reason, when the side plate members are relatively moved along the second direction, the coupling work can be performed from either side of the second direction.

  Furthermore, a configuration is proposed in which the one side plate member and the other side plate member have the same size and shape.

  By adopting such a configuration, it becomes possible to mass-produce one side plate member and the other side plate member using a common mold or the like, and it is possible to suppress the manufacturing cost of the cylindrical body for the storage permeation tank as a whole. It becomes possible. In addition, since one type of side plate members can be combined with each other to form the cylindrical body for the storage and permeation tank, the number of parts of the cylindrical body for the storage and permeation tank can be reduced as a whole. When the one side plate member and the other side plate member have the same size and shape as described above, the wide hole portion of the hole portion of the sliding engagement portion extends along the second direction. If it is formed on both sides of the narrow hole portion, both side plate members can be appropriately combined.

  Further, the side plate member may be L-shaped in a cross section orthogonal to the axis of the cylindrical body for storage and permeation tank.

  By setting it as this structure, at the time of manufacture of this side plate member, a rib etc. can be provided in the corner | angular part bent to the L shape, and intensity | strength can be raised previously. In addition, for example, the number of side plate member coupling portions is smaller than that of using four flat side plate members to form a cylindrical body having a rectangular cross section, so that the strength is stable and the labor for coupling work at a construction site or the like is reduced. be able to. Further, the molding cost can be reduced as compared with the integrally molded cylindrical body, and it is difficult to take trouble when transporting from a manufacturing factory or the like.

  Moreover, this invention is the cylindrical body for storage permeation tanks which has the connection structure of the side plate members in the said cylindrical body for storage permeation tanks.

  As described above, the cylindrical body to which the above configuration is applied is easy to connect the side plate members at the construction site and the like, and takes up less space than the one integrally formed from the beginning, and the extra work load is reduced. . In addition, the storage and penetration tank equipped with a cylindrical body with such a construction is much easier and shorter in construction time than conventional methods, even when the work site is narrow or the work period is limited. It becomes possible to do.

  In the storage, the top plate is disposed at one end of the cylindrical body for the storage and permeation tank, and the bottom plate is disposed at the other end of the cylindrical body for the storage and permeation tank. This is a box for an infiltration tank.

  By adopting such a configuration, the side plate members constituting the cylindrical body for the storage and permeation tank are sandwiched between the top plate and the bottom plate. Is prevented.

  Further, the present invention is a method for connecting the side plate members constituting the cylindrical body for the storage and permeation tank, wherein one side plate member and the other side plate member are connected to the axis of the cylindrical body for the storage and permeation tank. By approaching along a first direction perpendicular to each other, the movement restricting portion and the movement restricted portion are engaged with each other so as to be relatively movable only in a second direction perpendicular to the first direction, and then By moving the side plate members relative to each other along the second direction with the movement restricting portion and the movement restricting portion engaged, the slide engaging portion and the slide engaged portion are Are joined to each other, and the side plate members are joined to each other.

  By setting it as this structure, it becomes possible to assemble the cylindrical body for storage penetration tanks efficiently.

  The coupling structure according to the present invention has an excellent effect that the coupling work is easy, the work space is not required to be wide, and the obtained cylindrical body is prevented from rattling.

  In addition, the cylindrical body for the storage and permeation tank of the present invention is easy to join side plate members at the construction site, takes up less space than the one integrally formed from the beginning, and can reduce unnecessary work load. effective.

  Moreover, since the said side plate member is clamped by the top plate and the bottom plate, the said storage permeation tank box of this invention has an effect which can prevent the position shift of side plate members.

  Further, the coupling method of the present invention is configured such that the movement restricting portion and the movement restricting portion are engaged, and the slide engaging portion and the slide engaged portion are engaged in this engaged state. As compared with the conventional configuration, the burden on the worker is greatly reduced.

(Binding structure 1 and bonding method)
Hereinafter, a procedure for joining the side plate members 3 and 4 to obtain the cylindrical body 2 will be described. In the following, the procedure for joining the side edge 5 of one side plate member 3 and the side edge 6 of the other side plate member 4 will be described, and the side edge 6 of the one side plate member 3 and the other side plate will be described. Since the procedure for joining the side edge 5 of the member 4 is the same procedure, the description thereof is omitted.

(First stage)
First, as shown in FIG. 4, the side edge portion 5 of one side plate member 3 and the side edge portion 6 of the other side plate member 4 are arranged to face each other as shown in FIG. 4. The side plate member 3 is configured such that the wide head portion 17 of the slide engagement portion 15 of the side plate member 3 is inserted into the wide hole portion 26a of the hole portion 26 of the slide engagement portion 25 of the side plate member 4. , 4 are made to approach each other along the X-axis direction (that is, the first direction). Then, as shown in FIG. 5a, as shown in FIG. 5b, the protrusion 12 of the movement restricting portion 11 and the protrusion 22 of the moved restricting portion 21 come into contact with each other and the protrusions 12, 22 are bent. The restriction claw 13 of the protrusion 12 and the restricted claw 23 of the protrusion 22 are locked together. And as shown in FIG. 6, the said movement control part 11 and the said to-be-moved control part 21 engage, and the side edge parts 5 and 6 are faced | matched.

  Thus, in the state where the movement restricting portion 11 and the movement restricting portion 21 are engaged, the protrusions 12 and 22 are overlapped, and the movement restricting portion 11 and the movement restricting portion 21 However, the movement is restricted in the Y-axis direction, and they can slide in the Z-axis direction. That is, since the movement restricting portion 11 and the movement restricting portion 21 have such an engagement mechanism, the side plate members 3 and 4 are in a loose fitting state in which relative movement is allowed only along the Z-axis direction. The members 3 and 4 are temporarily fixed.

(Second stage)
Next, as the second stage, the side plate members 3 and 4 are moved along the Z-axis direction, which is the only movable direction, with the movement restriction portion 11 and the movement restriction portion 21 in the engaged state. As shown in FIG. 7, the neck portion 16 of the slide engagement portion 15 is positioned in the narrow hole portion 26 b of the slide engagement portion 25. Then, the wide head portion 17 faces the narrow hole portion 26, and the slide engagement portion 15 and the slide engagement portion 25 are locked in the X-axis direction. As a result, the connecting operation between the side plate members 3 and 4 is completed, and the cylindrical body 2 as shown in FIG. 1 is obtained. Since the pair of side plate members 3 and 4 have the same size and shape, in the coupling structure 1 in the side edge portion 5 of one side plate member 3 and the side edge portion 6 of the other side plate member 4, one (for example, When the wide head portion 17 is inserted into the wide hole portion 26a on the upper side and coupled, the side edge portion 6 of one side plate member 3 and the side edge portion 5 of the other side plate member 4 The wide head portion 17 is inserted into and coupled to the wide hole portion 26a (for example, the lower side).

  Thus, in the coupling structure 1 of the present embodiment, the movement restricting portion 11 and the movement restricting portion are first loosely fitted by moving the side plate members 3 and 4 in the X-axis direction (first direction). This restricts the movement of the side plate members 3 and 4 in a predetermined direction, thereby reducing the burden on the operator thereafter.

  Further, by providing a plurality of movement restricting portions 11 and slide engaging portions 15 and corresponding movement restricted portions 21 and slide engaged portions 25 on the side edge portions 5 and 6, sufficient strength can be obtained. It can be set as the cylindrical body 2 which has. In particular, the slide engagement is achieved by alternately arranging the movement restricting portion 11 and the slide engaging portion 15 or the movement restricting portion 21 and the slide engaged portion 25 alternately at the side edge portions 5 and 6. When engaging the portion 15 and the slide engagement portion 25, the deflection of the side edge portions 5 and 6 corresponding to the peripheral portion of the slide engagement portion 15 and the slide engagement portion 25 is suppressed to facilitate the work. can do.

  In addition, since the connecting structure 1 of the present embodiment has a shorter distance for moving the side plate members 3 and 4 relative to the conventional configuration, the operation can be performed even if the space required for the connecting operation of the side plate members 3 and 4 is narrow.

  Further, since the wide hole portions 26a of the sliding engagement portion 25 are provided on both sides of the narrow hole portion 26b, the operator slides the side plate members 3 and 4 from the desired side in the Y-axis direction. Can be combined.

  When the cylindrical body 2 is used in a storage permeation tank, a top plate (not shown) is provided at the upper end of the cylindrical body 2 and a bottom plate (not shown) is provided at the lower end. It is used after making it a box for a storage penetration tank. Thus, by arrange | positioning a top plate and a baseplate, the slide in the up-down direction of the side-plate members 3 and 4 is controlled. In addition, about a construction of a storage penetration tank, a well-known thing is used suitably.

  The present invention is not limited to the above-described embodiments, and can be appropriately changed in design without departing from the gist of the present invention.

  For example, the number of the movement restricting portions 11, the slide engaging portions 15, the movement restricting portions 21, or the slide engaged portions 25 disposed on the side edge portions 5 and 6 can be appropriately changed.

  Further, the movement restricting portion 11 and the slide engaging portion 15 are disposed on the side edge portion 5 of the side plate members 3 and 4, and the movement restricting portion 21 and the slide engaged portion 25 are disposed on the side edge portion 6.
