Each civil engineering structure unit 3 is provided with the resin net 4 (resin sheet) as a flexible sheet | seat body, as shown in FIG. The resin net 4 is integrally formed so as to form a lattice structure (including mesh shape or mesh structure, etc.), and the surface (one side) and the back side (other side) are almost without step. There is approximately one face state each. The outer circumferential shape of this resin net 4 is formed in substantially square shape (for example, one side is around 2m), and the strip | belt-shaped cloth member 5 is enclosed and attached to the whole edge part ( For example, sewing). The strip-shaped cloth member 5 is provided with a ring (ring) 6 made of cloth at predetermined intervals, and the ring 6 made of cloth makes the civil construction unit 3 the construction surface 1a. In the case of pulling up and conveying to the ground, it is used directly or indirectly in a hook hole such as a crane or a lifting mechanism, and the civil engineering structure 1 is constructed by laying the unit 3 for civil construction on the construction surface 1a. In this case, as shown in Fig. 14, it is also used as a connection hole for passing the latch 7, which is a connecting tool, in order to connect adjacent units for civil engineering structures. In Fig. 2, the connection by the latch 7 is omitted.

As shown in Figs. 1 and 2, the civil construction unit 3 includes a plurality of natural stones 8 as a plurality of civil construction materials. As the natural stone 8, not only aldol but also crushed stone is used, and the size thereof is about 100 to 500 mm in diameter, and a relatively flat surface is selected to form the fixing hole 9. The natural stone 8 is provided in a state where the fixing hole 9 is directed to the resin net 4, and is disposed up to every corner on the surface side of the resin net 4.

To install each natural stone 8 with respect to the resin net 4, as shown in Figs. 3 and 9, as the seat plate (plate), the seat 10 (lock) 10, A fixing anchor 11 is used as the fixing tool. As the seat 10, one made of stainless steel, one coated with a galvanized steel plate or a zinc aluminum plate, etc. is used. The seat 10 is shown in FIGS. 4 and 5 by press molding or the like. As described above, a plate-shaped main body 12, a bulging portion 13 (extended and raised portion) as a protrusion, and a through hole 14 are provided. The plate-shaped main body 12 is formed in the shape of a disk in a radially inward direction of the seat 10 in a disk shape, and occupies most of the seat 10. The bulging part 13 protrudes from the plate surface of the plate-shaped main body 12 at the edge part of the plate-shaped main body 12, and is provided. This bulging part 13 is formed in the seat 10 in an annular shape, and in this embodiment, the plate-shaped main body 12 is located as a partition area inside the annular shape. In addition, the distal end portion of the bulging portion 13 has a round shape, and in this embodiment, the round shape has an arc-shaped round shape as shown in FIG. The through hole 14 is fitted with the shaft portion of the fixing anchor 11, the position of which is the radial center portion of the seat 10. In this seat 10, the bulging portion 13 is placed on the natural stone 8 via the resin net 4, and at this time, a constant space 15 between the plate-shaped body 12 and the resin net 4 ) Is formed (see Fig. 9).

The fixing anchor 11 fixes itself to the natural stone 8, and as shown in Figs. 6 and 7, the shaft 16 for pressing and fixing the seat 10 and the root of the shaft 16 is fixed. The head 17 provided at the side end part (upper part in FIG. 7) is integrally provided. The shaft 16 has a diameter smaller than that of the fixing hole 9, the eyes of the resin net 4, and the through hole 14, so that the shaft 16 can be inserted therein. A plurality of (plural) protrusions 18 extending in the order are formed sequentially in the circumferential direction. Moreover, the curved part 19 is formed in the axial part 16 between the axial center part and the front-end | tip, and the axial center of the axial part 16 is extended laterally (expanded), and the curved part 19 is formed. As shown in FIG. 8, the amount of expansion of the curved portion 19 is set so as to project radially outward from the fixing hole 9 when the tip of the shaft portion 16 is inserted into the fixing hole 9. For this reason, when the shaft part 16 is press-fitted into the fixing hole 9, as shown in FIG. 9, the curved part 19 will be in a state where the curved part 19 is pressed down (a state where curvature will become small), and the shaft part 16 will be The protruding portion of the curved portion 19, the distal end of the curved portion 19 and the root portion on the same side are coupled to the inner wall of the fixing hole 9 and the shaft portion 16 is fixed to the fixing hole 9. do. Furthermore, in this case, the projection 18 on the outward side of the curved portion 19 increases the engagement area of the shaft portion 16 with respect to the inner wall of the fixing hole 9, as shown in FIG. Restriction on the rotation of the shaft 16 is tightened.

As shown in Fig. 9, the head 17 of the fixing anchor 11 is larger in diameter than the through hole 14 of the seat 10 as well as the shaft 16. Since the head portion 17 presses the shaft portion 16 into the fixing hole 9 in a state where the seat 10 is placed on the natural stone 8 with the bulging portion 13 interposed through the resin net 4. And a function of applying a pressing force for deforming the plate-shaped main body 12 and the bulging portion 13 of the seat 10, and also a function of a stopper that restricts the seat 10 from being pulled out.

Accordingly, when the fixing anchor 11 fixes the natural stone 8 with respect to the resin net 4, as shown in FIG. 9, the shaft portion 16 holds the seat 10 and the resin net 4. Passed through and held in the fixing hole 9, the head 17 deforms the plate-shaped body 12 and the bulge 13 of the seat 10 in this state. As a result, the fixing anchor 11 applies a spring force to the natural stone 8 via the resin net 4 by the bulging portion 13, and the seat 10 and the natural stone 8 apply the resin net 4. In this state, the natural stone 8 is provided in the resin net 4 accurately and firmly (in the state in which the natural stone 8 cannot be rotated). In this case, in addition to the increase in the pressing force by the fixing anchor 11, the bulge 13 shown in Fig. 9 is pushed out to increase the contact area with the resin net 4, so that a locally large force acts. This prevents the resin net 4 from being damaged.

In this case, the concrete block wall surface (concave area, boundary line, etc.) already installed is made flat with mortar, etc., while each civil construction unit 3 has a seat (10) (all or several seats in each civil construction unit). An adhesive is applied to (10) so as to cover the seat 10, and the seat 10 of each civil construction unit 3 is bonded to the mortar surface (construction surface) with the adhesive interposed therebetween. Thereby, not only the adhesive surface can be secured with the seat 10 in each civil construction unit 3, but also the plate-shaped main body 12 (compartment zone) deformed with the fixing of the natural stone 8 is provided. A sufficient adhesive can be secured (refer to the concave portion in which the deformed plate-shaped body 12 is formed in Fig. 9), and each civil construction unit 3 can be reliably held on the construction surface made of mortar. Of course, in this case, the ring 6 made of the cloth member of the resin net 4 may be used for connection, but it is not necessary to use it basically.

Therefore, if the civil engineering structure unit 3 is used, it is possible to simply change the wall surface of the concrete block already installed to a natural wall surface (natural stone exists on the surface).
