Each of the through holes 17 can be provided over the entire surface of the inner plate portion 102 defined by the rib 15.

Referring to FIG. 15, the inner plate portion 102 is installed in the middle portion of the thickness of the base portion 100, and is connected to each of the opening portion 16, the base portion 100 and a plurality of adjacent ribs 15. .

Further, each of the plurality of ribs 15 includes a structure in which one end is connected to the outer frame portion 110 of the base portion 100 and the other end is connected to the opening portion 16. The ribs 15 may be integrally formed when the face plate member 10 is formed, or may be added after the face plate member 10 is formed. According to the above-described structure, the face plate member 10 has excellent mechanical strength, and the inner plate portion 102 is thinner than the opening portion 16, the base portion 100 and the adjacent ribs 15, so that the face plate member 10 is lightened. can do. However, as shown in FIG.
The rib 15 may be provided only on one surface side of the inner plate portion 102.

As described above, the structure shown in FIG.
According to the structure in which the face plate member 10 has the opening 16 and the through hole 71, the face plate member 10 shown in FIGS.
In addition, all the advantages of the structure can be obtained, the total weight can be reduced, and excellent mechanical strength can be obtained. In addition, since rainwater and the like can flow through the openings 16, the storage space can be efficiently and widely used.

Further, the storage and permeation facility will be left for a long period of time with dust and mud settling and remaining at the bottom. The aperture 16 is
It is preferably designed to have a diameter of about 1500 mm, and an operator can perform maintenance management such as removal of dust and mud inside the structure 50 through the opening 16.

FIG. 17 is a perspective view showing still another embodiment of the face plate member according to the present invention, and FIG. 18 is a perspective view showing still another embodiment of the face plate member according to the present invention. The object of the present invention is to
An object of the present invention is to provide a structure having excellent mechanical strength and capable of easily performing an assembly work, and a facility for storing and infiltrating rainwater etc., and these problems will be described with reference to FIGS. 1 to 13. It has already been described focusing on the connecting structure of the face plate member 10 and the connecting member 30. The specific shape of the opening 16 is not limited to the circular shape as long as the above-mentioned problems can be solved. For example, the specific shape of the opening 16 may be a polygonal shape other than the elliptical shape shown in FIG.

Similarly, the planar shape of the base portion 100 of the face plate member 10 is not limited to the square shape. The face plate member 10 shown in FIG. 18 is different from the face plate member 10 shown in FIGS. 1 to 17 in that the base portion 100 has a substantially circular planar shape, and the face plate member 10 is parallel to and separately opposed to each other on its circumference. 2 sides X1,
It is provided with X2, Y1 and Y2, and a mounting portion 11.
As described above, since the base member 100 has the flat shape, the face plate member 10 can be transported in a non-bulky manner while keeping the occupation rate in the storage space low. Therefore, the outer shape of the base 100 is not limited to a square shape or a polygonal shape, and may be a circular shape as shown in FIG.

Also in the face plate member 10 shown in FIG. 18,
It is possible to form a structure by arranging a plurality of the elements continuously in the length direction and connecting the attachment portion 11 and the connecting member 30 to each other. Similarly, since the base portion 100 has at least two sets of two sides X1 and X2 and Y1 and Y2 which are opposed to each other and are parallel to each other, it is possible to easily and stably stack a plurality of structures in a storage and permeation facility. You can

Further, the face plate member 10 shown in FIG.
Unlike the storage and permeation facility shown in FIGS. 1 and 17, since the plane shape of the face plate member 10 is substantially circular, the structure has a substantially cylindrical shape, and a non-contact space is created between adjacent structures. . Therefore, the storage infiltration facility can efficiently use the storage space.

Although the contents of the present invention have been specifically described above with reference to the preferred embodiments, those skilled in the art can adopt various modifications based on the basic technical idea and teaching of the present invention. That is self-evident.
