  However, the attachment member of the sand collection frame of Patent Document 1 is configured to sandwich the upper end of the sand collection frame by the repulsive force when the separation between the locking portion and the holding portion is widened. There was a problem that the repulsive force was reduced and the sand collecting frame was disengaged.

  In Patent Document 1, the mounting member is difficult to move in the width direction, but the upward movement is not restricted. Therefore, when the sand collecting frame is attached to the lower assembly member, or the sand collecting frame is set to high pressure. When an external force is applied to the sand collection frame such as when washing with a jet, etc., and the sand collection frame rises, the mounting member moves upward together with the sand collection frame, and the installation member comes off the sand collection frame and collects the sand. There has been a problem that the receiving frame is greatly displaced from a predetermined position.

  The present invention has been made in view of the above-described problems. By restricting the upward movement and making it difficult to come off from the sand collection frame, the holding state of the mounting member can be secured, and An object of the present invention is to provide a sand collecting frame attachment member and a rainwater storage and penetration facility capable of stably maintaining the position and posture of the sand receiving frame for a long period of time.

  In order to achieve the above object, in the mounting member of the sand collecting frame according to the present invention, the mounting member fitted vertically is provided in the lower mounting member of the mounting member, and the bottom plate and both side ends thereof are provided. A groove-shaped sand collecting frame having a side plate to be erected, and for collecting rainwater in the basement and holding the sand collecting frame in the lower assembly member in a rainwater storage and penetration tank that flows out or permeates outside. The sand collecting frame mounting member is provided so as to protrude from the lower surface of the upper assembly member, and has a receiving frame holding portion that engages with each of the upper end portions of both side plates of the sand collecting frame. The sand receiving frame holding part is brought into contact with an upper locking wall that regulates lifting of the sand receiving frame by bringing the lower surface into contact with the upper end part, and the side surface of the upper end part. Orthogonal to the horizontal axis of the receiving frame axis It is characterized in that it comprises a side engaging wall for restricting the movement in the direction.

  The mounting member according to the present invention is provided so as to protrude from the lower surface of the upper assembly member, the upward movement of the attachment member is restricted by the upper assembly member, and the vertical direction of the receiving frame holding portion is The position does not move. Therefore, when the sand collection frame is about to float due to some external force, the mounting member itself will not move upward even if its upper end abuts against the upper locking wall of the frame holding unit. The rising of the sand collecting frame can be restricted by the upper locking wall. Further, since the side locking wall of the mounting member is located on the side of the upper end portion of the sand collection frame, even if the sand collection frame attempts to move in the width direction (lateral direction), the movement is caused by the side locking wall. It will be regulated.

  Therefore, even when an external force is applied to the sand collection frame during construction to attach the sand collection frame to the lower assembly member or when the sand collection frame is washed using a high-pressure jet, etc., it is attached together with the sand collection frame. The member is not lifted or displaced in the width direction, and is not easily detached from the sand collection frame, the holding state can be secured, and the position and posture of the sand collection frame can be maintained. In addition, since the mounting member is not a holding structure that uses the repulsive force, there is no problem that the holding force decreases as the repulsive force decreases with long-term use. Can be stably maintained over the long term.

  Even when the mounting member is provided separately from the upper assembly member, the mounting member is pressed from above by the upper assembly member and the posture is stable. Even if this works, it is possible to prevent the position and posture from moving.

  Furthermore, in this invention, an attachment member can be directly attached with respect to the upper assembly member which comprises a rainwater storage penetration tank, and an attachment member is attached between an attachment member and an assembly member like the past. This eliminates the need for a separate member, and thus suppresses an increase in member costs.

  Moreover, in the mounting member for the sand collecting frame according to the present invention, the upper assembly member is provided with a lateral rib extending from the lower surface thereof and extending along the width direction of the sand collecting frame. It is preferable that the member is formed with a concave groove-shaped fitting recess that is detachably attached to the lateral rib.

Therefore, the attachment member does not move in the receiving frame axial direction, and can be held in a stable posture with respect to the sand collection receiving frame.

  In the sand collecting frame mounting member according to the present invention, the upper assembly member is provided with a peripheral wall rib that is a part of the peripheral wall and extends along the width direction. It is preferable that the fitting recess is fitted and mounted.

  In this case, the mounting member can be easily attached to the upper assembly member using the peripheral wall rib. And since an attachment member is arrange | positioned at the surrounding wall rib located in the outer peripheral part of an upper assembly member, it becomes easy to mount an attachment member from the outer side of an assembly member, and it can improve workability | operativity. In addition, since it is easily visible from the outside even after assembly, there is an advantage that it is easy to visually confirm the holding state with respect to the sand collecting frame or the mounting state of the mounting member itself with respect to the upper assembly member.

  In the sand collecting frame mounting member according to the present invention, the receiving frame holding portion includes the upper locking wall and a pair of side locking walls sandwiched from both sides of one upper end of the sand collecting frame. It is preferable that it has the concave shape which has these.

  In this case, since the upper end portion of the sand collection frame is surrounded so as to be straddled by the concave portion composed of the upper locking wall and the pair of side locking walls, the sand collection frame is lifted and the width direction The movement to the can be reliably controlled.

  In the sand collecting frame mounting member according to the present invention, at least one of the pair of side locking walls, the surface facing the sand collecting frame is gradually lowered toward the sand collecting frame. It is preferable that a tapered surface that is inclined in a direction away from the upper end portion in the width direction is formed.

  In this case, since the opening side (lower side) of the interval between the side locking walls located on both sides in the width direction of the upper end portion of the sand collecting frame is widened, On the other hand, it becomes easy to perform the work when it is held by the receiving frame holding part, and the workability can be improved.

  Further, in the sand collecting frame mounting member according to the present invention, the sand collecting frame is provided with an upper edge curl portion extending from an upper end portion thereof toward an outer side in the width direction of the sand collecting frame. At the lower end of the outer wall portion located outside the sand collection frame in the width direction of the portion locking wall, a claw portion that engages with the lower end of the upper edge curl portion projects toward the side plate of the sand collection frame. Preferably it is.

  In this case, since the upper edge curl portion of the sand collecting frame is restricted to move downward by the claw portion of the mounting member, for example, the sand collecting frame is inclined in a direction rotating around an axis along its length direction. Even if one upper end portion of the sand collection frame is going to move downward, the movement of the upper edge curl portion is restricted by the claw portion, and it is more difficult to come off from the sand collection frame. A holding state can be secured.

  The rainwater storage and infiltration facility according to the present invention has the above-described sand collecting frame mounting member, temporarily stores rainwater embedded in the ground and flowing down from the surface of the road, and releases and permeates it outside.

The plurality of lower assembly members 3 arranged in X are arranged so as to be continuous in the length direction X over the whole.

As shown in FIG. 4, the attachment member 10 is detachably attached to the peripheral wall rib 25 of the upper assembly member 2, and the fitting recess 11 formed in a groove shape extending along the width direction W; It has the receiving frame holding | maintenance part 12 engaged with each of the upper end part 4A of the both-sides board 42 of the sand collection frame 4.
In the fitting recess 11, the groove 11 a along the width direction W fitted to the peripheral wall rib 25 and the other groove 11 c fitted to the reinforcing rib 25 a at the center of the width direction W are perpendicular to each other. It is formed to intersect. The other concave groove 11 c is provided so as to slightly protrude from one side surface of the fitting concave portion 11.

  The receiving frame holding portions 12 are provided on both sides in the width direction W on the lower surface 11 b of the fitting recess 11. Specifically, the upper locking wall 13 located above the upper end portion 4A of the sand collecting frame 4 and the side locking walls 14 positioned on both sides of the upper end portion 4A (the one positioned outside in the width direction W). Is the outer wall portion 14A, and the inner wall portion 14B is the inner wall portion 14B. And the lower end of the side part locking wall 14 is located below the upper surface 4a of the upper end part 4A of the sand collecting frame 4. That is, the receiving frame holding part 12 has a concave shape due to the upper locking wall 13 and the outer wall part 14A and the inner wall part 14B sandwiched from both sides of one upper end part 4A of the sand collection receiving frame 4.

The inner wall portion 14B is formed with a tapered surface 14a which is inclined on the surface facing the sand collection frame 4 in a direction away from the upper end 4A of the sand collection frame 4 in the width direction W as it goes downward.
The outer wall portion 14A has a longer length than the inner wall portion 14B and extends in the vertical direction.

As shown in FIG. 3, the separation between the inner wall portion 14 </ b> B and the outer wall portion 14 </ b> A may coincide with the width dimension of one upper end portion 4 </ b> A of the sand collection frame 4 and may be a contact interval. Or you may make it provide slightly larger than the width dimension of the said upper end part 4A, and since it becomes possible to absorb a construction error in this case, there exists an advantage that construction becomes easy. Further, as shown in FIG. 4, the upper catching wall 13 is fitted with the fitting recess 11 of the mounting member 10 so as to be sandwiched between the peripheral ribs 25 of the upper assembly member 2. 4 may be in contact with the upper surface 4a from above, or may be a position having a slight gap with respect to the upper surface 4a. In addition, since it becomes possible to absorb the elastic deformation of the assembly members 2 and 3 and the construction error of the attachment member 10 and the sand collection frame 4 by providing such a gap, the workability is improved. be able to.
In short, what is necessary is just to be provided so that the upper end part 4A of the sand collection frame 4 may be enclosed by the recessed part formed by the upper part locking wall 13 and a pair of side part locking wall 14A, 14B. That is, in this state, the sand collection receiving frame 4 is lifted and moved in the width direction W by the receiving frame holding unit 12 and held at a desired position.

According to the mounting member of the sand collecting frame described above, the following operational effects are obtained.
That is, as shown in FIG. 1, the mounting member 10 of the sand collecting frame of the present embodiment is provided so as to protrude from the lower surface of the upper assembly member 2, and the upward movement of the mounting member 10 is performed. It is restricted by the upper assembly member 2 and the vertical position of the receiving frame holding part 12 does not move. Therefore, when the sand collection frame 4 is subjected to some external force and tries to float up, the mounting member 10 itself moves upward even if the upper end 4A abuts against the upper locking wall 13 of the frame holding unit 12. Therefore, the floating of the sand collecting frame 4 can be restricted by the upper locking wall 13. Further, since the side locking walls 14 (the outer wall portion 14A and the inner wall portion 14B) are located on the side of the upper end portion 4A of the sand collection frame 4, the sand collection frame 4 tries to move in the width direction W (lateral direction). Also, the movement is restricted by the side locking walls 14 (14A, 14B).

Therefore, even when an external force is applied to the sand collection frame 4 during construction for attaching the sand collection frame 4 to the lower assembly member 3 or when the sand collection frame 4 is cleaned using a high-pressure jet or the like. The mounting member 10 is not lifted or displaced in the width direction together with the sand receiving frame 4, and is difficult to be detached from the sand collecting frame 4, and the holding state can be secured. The position and posture of the sand receiving frame 4 Can be maintained.
In addition, since the mounting member 10 is not a holding structure using a repulsive force, there is no problem that the holding force is lowered as the repulsive force is reduced by long-term use. And maintain a stable posture in the long term.

  Further, even when the mounting member 10 is provided separately from the upper assembly member 2 as in the present embodiment, the mounting member 10 is pressed from above by the upper assembly member 2 so that the posture is maintained. Since it is stable, even if an external force acts on the mounting member 10 itself, it is possible to prevent the position and posture from moving.

  Furthermore, the attachment member 10 can be directly attached to the upper assembly member 2 constituting the rainwater storage / osmosis tank 1, and the attachment member is attached between the attachment member and the assembly member as in the prior art. Since the separate member is not necessary, an increase in the member cost can be suppressed.

  Further, since the mounting member 10 is formed with a concave groove-shaped fitting recess 11 that is detachably mounted on the peripheral wall rib 25, the mounting member 10 mounted on the upper assembly member 2 has a length direction. Movement in X (in the receiving frame axial direction) is restricted. Therefore, since the attachment member 10 does not move in the receiving frame axial direction, it can be held in a stable posture with respect to the sand collection receiving frame 4.

In the present embodiment, the attachment member 10 can be easily attached to the upper assembly member 2 by using the peripheral wall rib 25.
Moreover, since the attachment member 10 is disposed at the position of the peripheral wall rib 25 located on the outer peripheral portion of the upper assembly member 2, it is easy to mount the attachment member 10 from the outside of the assembly member, and the workability is improved. Can be improved. In addition, since it can be easily seen from the outside even after assembly, there is an advantage that it is easy to visually confirm the holding state with respect to the sand collecting frame 4 or the mounting state of the mounting member 10 itself with respect to the upper assembly member 2.

  Further, in the mounting member 10 of the present embodiment, the upper end portion 4A of the sand collecting frame 4 is a concave portion in which the upper locking wall 13 and a pair of side locking walls 14 (the outer wall portion 14A and the inner wall portion 14B) are formed. , The sand collection frame 4 can be lifted and moved in the width direction W with certainty.

  Furthermore, a tapered surface 14a is formed on the inner wall portion 14B of the mounting member 10, and the opening side of the space between the outer wall portion 14A and the inner wall portion 14B located on both sides in the width direction W of the upper end portion 4A of the sand collecting frame 4 is provided. Since (lower side) has spread, at the time of construction, it becomes easy to carry out construction when holding the upper end portion 4A of the sand collection receiving frame 4 with the receiving frame holding section 12, and workability can be improved.

  As described above, in the mounting member 10 according to the present embodiment, the upper assembly member 2 restricts the upward movement of the mounting member 10 to make it difficult to come off from the sand collecting frame 4. The holding state can be secured and the position and posture of the sand collection frame 4 can be stably maintained over a long period of time.

  Next, another embodiment of the sand collecting frame mounting member according to the present invention will be described with reference to the accompanying drawings.
