2. Description of the Related Art As is well known, partition blocks are widely used in various applications to partition boundaries between buildings and parking lots. Conventional partitioning blocks are often made of heavy-duty materials such as concrete blocks to form a sturdy structure, and this is a very heavy labor for workers on site who transport and install the concrete blocks to the required locations. Was. There was also a high risk of injury from 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 smaller size block have been proposed.

However, in the case of the former lightweight block, the material is fragile and easily collapsed, and if it is not fixed to the ground, it may be too light and its position may be deviated by slight vibration. There was a serious drawback in that it did not fulfill the function of partitioning the most important element of the block, the boundary.

[0004] In the case of the latter small blocks, the weight of each block is reduced, so that the work such as transportation is easy, but the number of blocks required to draw a boundary line of a predetermined length is reduced. Is more than the number of blocks of the normal size, so that it is troublesome and the work efficiency is deteriorated.

FIG.

First, a description will be given of a partition block according to a first embodiment of the present invention. As shown in FIGS. 1 to 4,
The block of the first embodiment is formed of a plastic molded body 1 integrally molded in a hollow. This plastic molding 1
Can be formed by a blow molding method.
A supply / discharge port 2 through which the fluid W can be supplied and discharged is formed in a required position of the molded body 1 in an up-and-down relationship in communication with the inner space. An inlet 21 is formed above the molded body 1 more than an outlet 22, and when the block is installed, the inlet 21
When a fluid W such as water is supplied from 21 and the block is removed, the internal fluid W is discharged from the outlet 22. By filling the inner space with the fluid W in this manner, even if a lightweight member is used, the partition block can be stably installed. Although the water W is often used as the fluid W, a granular material such as sand having a higher specific gravity than water may be used in order to make it difficult to shift. The plastic molded body 1
There are formed three fitting holes 11 into which the support bar 3 can be inserted upright from the upper part to the lower part. A caldera-shaped concave portion 16 is formed directly below the fitting hole 11, and is provided so that the lower end of the fitting tube described later can be seated. Then, as shown in FIG. 3, the fitting cylinder 15 formed 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.
Is stably held by fitting into the concave portion 16. As shown in FIG. 4, a convex portion (conical projection in the illustrated example) 17 for a fitting cylinder is formed on the bottom of the molded body 1, and the fitting cylinder 15 is fitted to the convex portion 17 so as to fit. The fitting hole 11 can be formed by being inserted from above. The fitting hole
Any support rod 3 may be used as long as it can be inserted into the unit 11. For example, if bamboo or the like is inserted and arranged so as to surround it, not only can the boundary of the site be defined, but it can also be used as a fence. Pass to. On one side of the molded body 1, an ant tenon 12 to which an adjacent molded body 1 is to be connected.
A dovetail groove 13 for connecting the adjacent molded body 1 is formed in the opposite wall portion. By dovetailing the dovetail tenon 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 a second embodiment of the present invention will be described with reference to FIGS. Although the block of the second embodiment is very similar in appearance to the block of the first embodiment, the structure for configuring this block is different. As shown in FIGS. 5 to 8, a pair of integrally formed plastic hollow pieces 1a, 1a are connected to each other by connecting screws 4 in a back-to-back state. Each plastic hollow piece 1a can be formed by a blow molding method. Each plastic hollow piece 1
As in the block of the first embodiment, a supply / discharge port 2 for supplying and discharging the fluid W is formed in a required position a.1a in an up-and-down relationship with the inner space. Then, by connecting the hollow pieces 1a in a back-to-back state, a fitting hole 11 into which the support rod 3 can be inserted upright is formed as shown in FIG. In addition, as shown in FIG. 8, a fitting hole 11 having a structure in which a bottom portion penetrates may be formed. Further, since the joined plastic molded body 1A is composed of a pair of plastic hollow pieces 1a, 1a, it has greater strength than the block of the first embodiment. Peace 1a
By exchanging only the above, it is possible to form the combined plastic molded body 1A. The plastic molded body 1A can be naturally connected to the plastic molded body 1 of the first embodiment 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-described embodiments, and various modifications are possible within the scope of the claims. Thus, for example, it is also possible to change the shape of the plastic molded body, or to change the positions of the supply / discharge port and the fitting hole for the support rod.

In the second embodiment, it is also possible to produce a partition block having a variety of external designs by giving each plastic hollow piece a different color. Needless to say, any of these modifications falls within the technical scope of the present invention.

[0013]

As described above with reference to the embodiments, according to the present invention, since a plastic molded body integrally formed in a hollow is used, the weight is extremely reduced, and the on-site work during transportation and installation is performed. The burden on workers is greatly reduced, work efficiency is improved, and handling safety is high. Further, by filling a fluid such as water into the hollow space of the hollow plastic molded body, the partition block can be stably installed despite the use of a lightweight member. Therefore, there are many effects as described above,
The industrial practical value is very large.
