2. Description of the Related Art As is well known, partition blocks are widely used in various applications for partitioning boundaries such as buildings and parking lots. Conventional partitioning blocks are often made with a sturdy structure using heavy materials such as concrete blocks, and it is a heavy labor for workers on site to transport and install these concrete blocks. It was In addition, there was a great risk of being injured by dropping blocks during work. Therefore, in order to reduce the weight of the block as much as possible, a foam concrete block made of a lighter material and a block having a smaller size have been proposed.

However, in the case of the former lightweight block, the material is fragile and easily collapses, and if it is not fixed to the ground, it may be too light and the position may change due to slight vibration. There was a serious drawback in that it no longer fulfilled the function of partitioning the boundaries, which is the most important element of blocks.

In the case of the latter small block, the weight of one block is lighter, so that the work such as transportation is easier, but the number of blocks required to draw a boundary line of a predetermined length. Since the number of blocks is larger than the number of blocks of a normal size, there is a drawback that it is troublesome and the work efficiency becomes poor.

[0005]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems in the partition block used for defining the boundary of the site, etc. By using it, the burden on site workers is reduced, and stable installation is possible by filling the inner space with a fluid such as water, and it is light during transportation, resulting in good work efficiency and easy handling. It is a technical object to provide a highly practical and practical plastic hollow partition block.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in more detail below with reference to the embodiments shown in the accompanying drawings. 1 is a perspective view of the first embodiment of the present invention, FIG. 2 is a plan view of FIG. 1, FIG. 3 is a sectional view taken along the line AA in FIG. 2, and FIG. 4 is a sectional view of another embodiment of FIG. FIG. 5, FIG. 5 is a perspective view of a second embodiment of the present invention, FIG. 5 is a plan view of FIG. 6, FIG. 7 is a sectional view taken along line BB in FIG. 6, and FIG. 8 is a sectional view of another embodiment of FIG. It is a figure.

First, the partition block of the first embodiment of the present invention will be described. As shown in FIGS. 1 to 4,
The block of the first embodiment is composed of a plastic molded body 1 integrally molded in the hollow. This plastic molding 1
Can be molded by a blow molding method.
A supply / discharge port 2 capable of supplying and discharging the fluid W is formed in a required portion of the molded body 1 so as to communicate with the inner space and have a vertical relationship. The inlet 21 is formed in the upper part of the molded body 1 than the outlet 22, and when the block is installed, the inlet 21
A fluid W such as water is supplied from 21 and the fluid W inside is discharged from the discharge port 22 when the block is removed. By thus filling the inner space with the fluid W, the partition block can be stably installed even if a lightweight member is used. Although water is often used as the fluid W, a granular material such as sand having a larger specific gravity than water may be used in order to prevent the fluid W from slipping. The plastic molded body 1
Three fitting holes 11 are formed so that the support rod 3 can be inserted upright from the upper part to the lower part. A caldera-shaped recess 16 is formed immediately below the fitting hole 11 and is provided so that the lower end of the fitting cylinder described later can be seated. Then, as shown in FIG. 3, the fitting cylinder 15 molded separately from the plastic molded body 1 is formed.
Is inserted from above so as to fit into the fitting tube recess 16 at the bottom of the molded body 1 to form the fitting hole 11, and the fitting tube 15 is formed.
The lower end of is fitted into the concave portion 16 and is stably held. Further, as shown in FIG. 4, a fitting cylinder projection (conical projection) 17 is formed on the bottom of the molded body 1, and the fitting cylinder 15 is fitted to the projection 17 so as to straddle. The fitting hole 11 can also be formed by inserting from above. The fitting hole
Any support rod 3 may be adopted as long as it can be inserted in 11. If, for example, bamboo is inserted and arranged so as to surround it, not only can the boundary of the site be determined, but also a fence is excellent. Apply to. The dovetail 12 to which the adjacent molded body 1 is to be connected to one side surface of the molded body 1
And a dovetail groove 13 for connecting the adjacent molded bodies 1 is recessed in the opposite wall portion. By connecting the dovetails 12 to the dovetail groove 13 of the adjacent molded body 1, the molded bodies 1 can be sequentially connected, and the boundary can be partitioned very easily.

Next, a partitioning block according to the second embodiment of the present invention will be described with reference to FIGS. The block of the second embodiment is similar in appearance to the block of the first embodiment described above, but the structure for forming this block is different. As shown in FIG. 5 to FIG. 8, a pair of integrally molded plastic hollow pieces 1a, 1a are connected by a connecting screw 4 in a back-to-back state. Each of the plastic hollow pieces 1a and 1a can be molded by a blow molding method. Each plastic hollow piece 1
Similar to the block of the first embodiment described above, a supply / discharge port 2 capable of supplying and discharging the fluid W is formed in a required portion of a. Then, by coupling the hollow pieces 1a and 1a in a back-to-back state, as shown in FIG. 7, a fitting hole 11 into which the support rod 3 can be inserted upright is formed. Further, as shown in FIG. 8, it is also possible to form a fitting hole 11 having a structure in which the bottom portion penetrates. Further, since this combined plastic molded body 1A is composed of a pair of plastic hollow pieces 1a, 1a, it has a greater strength than the block of the first embodiment, and even if one hollow piece 1a is broken, its hollow Piece 1a
By exchanging only the above, it is possible to form the combined plastic molded body 1A. The plastic molded body 1A can be connected to the plastic molded body 1 of the first embodiment as a matter of course by the dovetails 12 and the dovetail grooves 13 provided on both sides.

Although the embodiments of the present invention are generally as described above, the present invention is by no means limited to the above-mentioned embodiments, and various modifications can be made within the scope of the claims. Thus, for example, the shape of the plastic molded body can be changed, and the positions of the supply / discharge port and the support rod fitting hole can be changed.

Further, in the second embodiment, it is also possible to manufacture a partition block having a variety of appearance designs by giving different colors to the respective plastic hollow pieces. It goes without saying that any of these modifications belong to the technical scope of the present invention.

[0013]

As described above with reference to the embodiments, according to the present invention, since the hollow integrally molded plastic body is used, the weight becomes extremely light, and the site work during transportation and installation is performed. The work load is greatly reduced, the work efficiency is improved, and the handling safety is high. In addition, by filling the inner space of this hollow plastic molded body with a fluid such as water, the partition block can be stably installed even though a lightweight member is used. Therefore, there are many effects as described above,
The industrial utility value is enormous.
