2. Description of the Related Art Conventionally, even temporary parking lots are usually installed in a structure that is almost the same as that of a permanent parking lot. You can simply spread gravel in the required area and make it flat, and use ropes etc. to divide the area into parking areas, or you can dig the required area slightly or not, spread gravel, and then compact the area, and then flatten the area. There are parking lots with concrete pavement, such as pouring asphalt to form a flat asphalt pavement, and dividing the area into parking lots with paint or the like, or concrete paved parking lots by pouring concrete instead of the asphalt.

Although the above-mentioned gravel parking lot is relatively easy to install, it is not easy to dismantle and remove, and it cannot be said that it is very convenient to use. Although asphalt and concrete parking lots offer good usability, they are not easy to install and are extremely troublesome to dismantle and remove. In order to solve these problems, the inventors of the present application have proposed several types of paving materials for temporary parking lots and temporary parking lots that are easy to install and dismantle and are easy to use.

One of them is a temporary parking system in which a sheet member is covered on the ground made into a smooth ground surface by compaction, and a large number of paving unit members are removably connected to each other and laid on the sheet member. It is a car yard (Unexamined Japanese Patent Publication No. 1-198907). Second, a large number of platforms are formed in a raised manner on the upper surface of the sheet-like base, and each of the platforms is used as a stepping platform on which a car can run or park. This is a paving member for a temporary parking lot (Japanese Unexamined Patent Publication No. 1-203502) with a drainage channel in the lower part located around the area. The third is
It consists of a plurality of independent pedestals on which treads are placed on the top surface of the frame, the periphery of the pedestals is a continuous rainwater circulation surface, and each of the four sides of the frame has a A temporary parking lot is provided with communication means for mutually distributing rainwater, etc. on the rainwater distribution surfaces of adjacent frames, and connecting means on each of the four sides of the frames to connect the adjacent frames when installed. This is a frame for laying footboards (Japanese Unexamined Patent Publication No. 1-214603). Fourth, the pavement for a temporary parking lot is made by fixing spacers scattered on a substrate material and having a tread material with a large number of permeable holes drilled on the substrate material, which is joined to the substrate material via the spacers. (Japanese Unexamined Patent Publication No. 1-239202). Furthermore, fifthly, on the bottom surface of the rectangular planar board, legs are installed, and on the top surface, tread boards are scattered, and on two sides adjacent to each other with one corner of the board in between, the corresponding legs and tread boards are installed. Each of the legs and the treadle at the corresponding positions are made to protrude outward from the edge of the board to form a female connection part, and the legs and the footboard are made to protrude outward from the edge of the board on the other two sides of the board. A paving member for a temporary parking lot (Japanese Patent Laid-Open No. 2-27002), in which the connecting male part is set back from the edge by a length corresponding to the protruding length of the legs and treads on at least the two sides. be.

[Problems to be Solved by the Invention] The five systems previously proposed by the inventor of the present invention are easy to install and dismantle, and can also function satisfactorily as a parking lot. Moreover, both can be used on sandy soils. Therefore, although there is no problem with these materials, the object here is to provide a paving material for temporary parking lots that is even more suitable for sandy soil and can be installed and dismantled more easily.

[0006]

[Means for Solving the Problems] The gist of the structure of the present invention is a paving material for a temporary parking lot, which has a subsidence prevention collar with fixed legs hanging from the lower surface at the intersection of net members. . In principle, the above-mentioned subsidence prevention flanges are constructed at all intersections in the net members. The net member may be made of a rope made of synthetic fiber or other various materials. The mesh may have a honeycomb shape or any other arbitrary shape. Most likely, a grid-like configuration would be simple and convenient. The dimensions of the mesh shall be appropriate from the viewpoint of constructing the pavement of the parking lot. For example, when the diameter of the rope is about 7 mm and the mesh shape is square, it is appropriate that the length of one side is about 150 mm to 200 mm. It goes without saying that the dimensions are not limited to these dimensions. The anti-subsidence collar may be completely fixedly attached to the intersection of the net members, or may be detachably attached. When the subsidence prevention collar is configured to be detachable, it can be configured as follows, for example. That is, the above-mentioned subsidence prevention flange includes a flange main body having a cross-shaped locking groove on the upper surface and a connecting hole that penetrates from the central cross part of the cross-shaped locking groove to the lower end of the fixed leg hanging from the lower surface, and the locking groove. A net restraining plate that inserts and locks the net member near the intersection point, and then holds down the net member from above in order to prevent the net member near the intersection point from separating from the locking groove, the net member itself and a net restraining plate provided with a locking leg that can be inserted into the connecting hole and fixed in a state where the vicinity of the intersection of the net is restrained.

[0007]

[Operation] Since the present invention is constructed as described above, it is very useful when a temporary parking lot is installed on a sandy area. After leveling the required sandy area as flatly as possible, the net member is spread out with the fixed legs of the subsidence prevention collar formed at the intersection points facing downward, and the fixed legs are successively driven into the ground and fixed. Basically, this is all that is required to complete the installation of a temporary parking lot. After that, each parking section can be constructed by stretching another rope or by coloring the ropes constituting the net member, if necessary. In a temporary parking lot configured in this way, the weight of vehicles and pedestrians is first directly supported by the subsidence prevention collar on which tires or people are placed, and then the weight is carried by the ropes that make up the net member. Since the load is distributed among other subsidence prevention collars and the load is not concentrated in one place, partial subsidence does not occur. Therefore, it is possible to maintain a sufficiently flat state, and it is possible to turn a sandy area into a flat and easy-to-use temporary parking lot. When the parking lot is no longer needed, the net member can be removed while pulling out the fixed legs of the subsidence prevention collar, and the dismantling and removal is complete. Net components can be folded to make them smaller.
It can be stored without taking up much space. Moreover, when necessary, it can be installed and reused as described above.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. As shown in FIGS. 1 and 2, a net member 1 is constructed by connecting rope materials in a grid pattern, and subsidence prevention flanges 3 with fixed legs 2 hanging down from the lower surface are arranged at all intersection points of the net member 1. The rope material used has a diameter of about 7 mm, and forms a square mesh when viewed from the plane of the net member 1. The length of each side of the mesh was approximately 200 mm.

The anti-subsidence flange 3 has a flange main body 4 with the fixed leg 2 hanging down from the center of the lower surface, as shown in FIG.
and a net restraining plate 5, and the collar body 4 has a cross-shaped locking groove 6 on its upper surface, and further has a cross-shaped locking groove 6.
A connecting hole 7 is drilled through the center cross portion of the fixing leg 2 to the lower end of the fixed leg 2 hanging from the lower surface. Further, the net restraining plate 5 has four restraining pieces 5b, 5b, . Furthermore, locking legs 8,
8 are suspended, and each lower end thereof has a barb 9 for engaging the lower end of the fixed leg 2 from the inside. Naturally, the length of the locking legs 8, 8, . . . is made to correspond to the length of the fixed leg 2. The width of the four holding pieces 5b, 5b, . . . is made slightly narrower than the locking groove 6.

As shown in FIG. 3, the net member 1 is placed in the locking groove 6 of the collar body 4 with the intersection point corresponding to the center of the connecting hole 7, and then the net is held down. The plate 5 has its circular base portion 5a corresponding to the connecting hole 7, and the holding pieces 5b, 5b, . . .
The net member 1 is lowered while corresponding to the above-mentioned locking groove 6.
It is fixed inside. And if you lower it like this,
a locking leg 8 hanging down from the peripheral edge of the circular base plate 5a;
8 fit into the connecting hole 7, and the barbs 9, 9, at the lower ends thereof are engaged with the lower ends of the fixed legs 2. In this way, net member 1
A subsidence prevention collar 3 is fixed at the intersection of the two. If this is done at all the intersections of the net members 1, the paving material for the temporary parking lot is completed.

[0011] Since this embodiment is constructed as described above, it is very useful when a temporary parking lot is installed on a sandy area. When installing this, the sandy area 10 for the temporary parking lot is leveled as flatly as possible, and then, as shown in FIG. Spread it out so that the fixed legs 2 of ... are facing down,
As shown in Figure 2, the fixed legs 2, 2...
Push it into the 0 to secure it. The fixed legs 2, 2, . . . can be easily pushed into the sandy ground 10 by stepping on them with one's feet. Basically, this is all that is required to complete the installation of a temporary parking lot. After that, each parking section can be configured by stretching another rope as needed or by coloring the ropes that make up the net member 1 at the corresponding positions.

[0012] In the temporary parking lot constructed in this way, the weight of vehicles and pedestrians is first received directly by the subsidence prevention collar 3 on which vehicle tires or people are placed, and their weight is absorbed by the net. It is distributed to other subsidence prevention collars 3, 3, . . . through the rope constituting the member 1, and since the load is not concentrated in one place, no local subsidence or the like occurs. Further, since the fixed legs 2, 2, . . . are driven into the sandy ground 10, the respective subsidence prevention flanges 3, 3, . . . do not move in the horizontal direction. Therefore, the temporary parking lot configured in this way can maintain a sufficiently flat state, and the sandy area 10 can be made into a flat and easy-to-use temporary parking lot.

[0013] When the parking lot is no longer needed, the net member 1 is removed while pulling out the fixed legs 2, 2... of the subsidence prevention flanges 3, 3..., and the dismantling and removal thereof is completed. Note that the fixed legs 2, 2, . . . can be easily pulled out from the sandy ground 10 by simply pulling up the net member 1. Furthermore, the net member 1 can be folded up to make it smaller, so it does not take up much storage space. This temporary parking lot paving material can be reused many times.

[0014]

Effects of the Invention The temporary parking lot paving material of the present invention is extremely easy to install and dismantle, and can be reused. In addition, it maintains good flatness even on sandy soil, making it possible to construct an easy-to-use parking lot.
