Description

The present invention relates to an engagement portion of a table-like unit member that forms a storage space such as a rainwater storage and penetration facility.

For the purpose of suppressing the outflow of rainwater and the like, rainwater storage and infiltration facilities are widely used in which unit members made of plastic or the like are arrayed and filled in the basement, and the periphery is appropriately covered with a sheet. For this purpose, for example, table-like unit members having cylindrical legs opened in a flat plate as shown in FIG. 6 are disclosed in Japanese Patent Laid-Open Nos. 10-252108, 11-222886, 2000-352080, and 2007. Disclosed and used in -2419.
In general, these table-like members are formed as a unit in which the cylindrical portions are opposed to each other, and the units are overlapped to form a storage space or a core of a lightweight embankment. The storage space is covered with a water-permeable sheet or a water-impervious sheet according to the purpose of use and the place of application, and necessary auxiliary equipment is installed to serve the above purpose.
There is a need for a method of securely engaging the unit and releasing it easily.

The present invention resides in a proposal of means for facilitating engagement and release of the table-like member.

The first aspect of the present invention provides a projecting portion and a hole portion as an engagement portion that allows engagement between the leg portion closing portions of the table-like member made of a square flat plate and a leg portion that opens to the flat plate and closes at the end portion, It is a table-like member provided with a cap portion that expands inside the concavity when passing through the hole at the tip of the protrusion.
The second aspect of the present invention provides a projection and a hole as an engagement portion that allows the flat plate portions to be engaged with each other on a flat plate portion of a table-like member that is formed of a square flat plate and a leg portion that opens to the flat plate and closes at the end portion. The table-like member is provided with a cap at the tip of the protrusion that extends inside the concavity when passing through the hole.

The present invention provides a projecting portion and a hole portion as an engagement portion that allows engagement between the leg portion closing portions of the table-like member that is a square flat plate and a leg portion that opens to the flat plate and closes at the end portion. Since the cap portion is provided at the tip so as to extend inside the concavity when passing through the hole portion, the engagement between the leg portions of the table-like members facing each other is easy and reliable.
The present invention provides a projecting portion and a hole portion as a mating portion that enables mating of the flat plate portions to each other on a flat plate portion of a table-like member that is formed of a square flat plate and a leg portion that opens to the flat plate and closes at an end portion. Since the cap portion that extends inside the concavity when passing through the hole portion is provided at the tip of the plate, the engagement between the flat plates of the table-like members facing each other is easy and reliable.

These are the conceptual diagrams of the table-shaped member which concerns on this invention. These are the enlarged views which show the example of the engagement part of a table-shaped member. These are the conceptual diagrams which show the engagement which forms the unit of the table-shaped member which concerns on this invention. These are the conceptual diagrams which show the contract of the unit which concerns on this invention. These are the conceptual diagrams which show storage penetration facilities, such as rain water, using the table-shaped member which concerns on this invention. These are the conceptual diagrams which show the conventional table-shaped member.

Hereinafter, the present invention will be described in more detail with reference to the drawings.
FIG. 1 is a conceptual diagram of a table-like member according to the present invention. 1A is a plan view, and FIG. 1B is a cross-sectional view taken along the line AA ′.
In the figure, the table-like member is composed of a square flat plate portion and four leg portions that open to the flat plate portion and have the other end closed. The closed end of the leg is provided with two protrusions and two holes in the figure. The tip of the protrusion has a shade shape, and when inserted into the hole, the shade portion shrinks and reopens after passing through the hole, so that it can be easily inserted and the engagement can be performed reliably. ing. The relative positions of the protrusion and the hole are the same as those of a normal joint, and the two facing each other are the protrusions and the other is the hole, but the two adjacent ones are the protrusions and the other is the hole. You can do it. Please refer to the enlarged view of Figure 2 for details of the engagement section. FIG. 2ab and FIG. 2cd show the engagement states for different engagement portions.

Further, as shown in FIG. 1, it is also possible to provide a similar engagement portion on the surface of the square flat plate portion so that the engagement between the flat plate portions can be easily and reliably performed.

3 and 4 are conceptual diagrams showing engagement states of the table-like members according to the present invention.
As shown in the drawing, in order to form a unit by engaging two table-like members with their leg closed end portions opposed to each other, it is necessary to engage 90 degrees with each other.
Also, in order to engage units, it is necessary to change the direction of units 90 degrees.

FIG. 5 shows a conceptual diagram when the units are arranged to form a storage space and used as a storage and penetration facility for rainwater or the like.
Enclose the storage space with wall material and cover it with a sheet to prevent the intrusion of sediment into the storage space, and install incidental facilities as needed such as inflow pipe, outflow pipe, overflow pipe, mud, manhole, orifice, etc. It can be used as a storage / penetration facility for rainwater and the like in the same manner as conventional unit members. In the case where the sheet is also used as an infiltration tank, a water-permeable sheet is used. In the case where groundwater is prevented from entering or stored rainwater is used effectively, a water-impervious sheet is also used.

The material such as the table-like member and the wall material can be made of an injection-moldable polyolefin such as polypropylene or a metal such as stainless steel, as in the conventional method using the unit member. Further, the number and shape of the leg portions of the table-like member can be appropriately changed. Preferably, the legs are tapered so that they can be combined in a nested manner.

As described above, the present invention is used as a storage / penetration facility such as rainwater or a core material for lightweight embankment.
