DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gutter forming member. The side groove forming member referred to in the present invention is not limited to a part thereof, for example, the one where the lid portion is exposed,
The one where the entire gutter is buried underground is also included.

[0002]

2. Description of the Related Art A so-called "U-shaped groove" formed by connecting U-shaped concrete unit members is provided on the side of a road for flowing rainwater. The concrete unit member forming the U-shaped groove is formed by pouring cement milk using cement as a raw material into a mold, drying the cement milk, and then extracting the cement milk from the mold.

[0003]

As described above, in a gutter forming member formed by pouring cement milk made of cement as a raw material into a mold, drying the cement milk, and then extracting from the mold, the density of concrete forming the gutter is low. for,
There is a problem that the thickness must be increased in order to increase the strength.

When the thickness is increased, not only the size of the side groove forming member is increased, but also the weight is increased, so that it is difficult for one worker to perform the laying operation, the construction period is lengthened, and the laying cost is increased. There was also a problem. In addition, it is said that it is difficult to apply a pattern in order to improve the removal from the mold when the cement milk is poured into the mold, dried, and then removed from the mold, in order to improve the removal from the mold. There were also problems.

[0005] On the other hand, in recent years, in urban areas, in terms of aesthetics and safety,
Communication cables such as power lines and light are buried underground. To bury communication cables such as power lines and light, first, traffic is cut off. Next, after digging up the road, laying the cable, and covering the soil above it, such work is performed for each cable to be buried, or because the above work is performed every time an extension is made,
There is also a problem that much labor and time are required to lay the cable, and the cost of the laying is further increased. In view of the above, the present invention has been proposed in view of the above-described problems, and aims to reduce the weight of a side groove forming member capable of easily forming a pattern on a surface and use a side groove formed by connecting the side groove forming members. Accordingly, it is an object of the present invention to easily lay various cables in a short time.

[0006]

In order to achieve the above object, a gutter forming member according to the present invention comprises: a main body portion having an opening at an upper portion and having a space for inserting an article therein; A lid that closes the opening so that it can be opened and closed, and a partition that partitions the space for article insertion of the main body into a plurality of sections,
The main body part, the lid body, at least the main body part of the partition body,
It is characterized by being formed by press molding in a mold using cement as a raw material. A substantially U-shaped or V-shaped groove is formed in the center of the bottom of the main body, and the partition body closes an opening on the upper surface of the groove.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view showing an embodiment of a gutter according to the present invention. FIG. 1 is an exploded view of the side groove member, FIG. 2 is a front view of the side groove member, and reference numeral 1 in the drawing generally shows the side groove member. The gutter member 1 includes a main body portion 2 at least a part of which is buried in the ground, a lid body 4 that closes an opening 3 of the main body portion 2 so as to be openable and closable,
The main body part 2, the lid 4 and the partitioning tool 5 are formed into a predetermined unit length, for example, 90 cm by stamping concrete by a press as described later. Have been.

The main body 2 has a cable or tube mounting portion 6 formed in the center of the bottom in a semicircular to U-shape, and plate-like portions 7 and 7 from both ends of the semicircular to U-shape.
Extend slightly obliquely upward. The ends of the plate-like portions 7.7 are formed in a state of rising upward, and a receiving portion 10 for receiving the side edge portion 9 of the lid 4 is formed at the upper end portion 8.8. Also,
The partitioning tool 5 is formed in a plate shape drawing a gentle arc, and both side edge portions 11 are formed with fitting edge portions that fit into the opening edges of the installation portion 6. Is installed in the opening portion of the installation section 6, whereby the internal space of the side groove member 1 is divided into a plurality (two).

The lid 4 is formed in a plate-like shape similar to the partitioning tool 5 and has a gentle arc and a thick central portion.
Fitting portions 13 that fit into the receiving portions 10 of the main body portion 2 are formed on both side edge portions. Next, the molding of the main body 2, the lid 4, and the partitioning tool will be described.
First, although not shown, a pair of upper and lower molding dies is attached between the rams of the press device. Next, the upper and lower molding dies are opened, a concrete material kneaded with cement as a raw material is put therein, and then the upper and lower molding dies are closed to mold the concrete material while dewatering.

Thereafter, the upper and lower molding dies are opened, the dehydrated molded product is taken out and cured and dried to complete the process. Each of the main body portion 2, the lid 4 and the partitioning member of the gutter forming member thus formed is formed by dehydrating a concrete material with a press device, so that the density of the concrete is increased, and the strength and rigidity are also increased. .

Next, a procedure for laying various cables or pipes using the side groove member 1 formed as described above will be described. As shown in the figure, first, a portion where a side groove is to be laid is dug up, and when the main body portion 2 is continued and installed so that an upper end portion thereof is substantially flush with the ground, a passage (article insertion space) 14 is formed therein. Is formed (see FIGS. 2 and 3).

For example, as shown in an imaginary diagram, a gas pipe or a pipe 16 such as a water supply pipe or a sewer pipe is laid on the installation section 6 of the cable or the pipe material of the passage 13 thus formed. Place the partitioning tool 5 and cover it. Next, when the opening of the installation part 6 is covered with the partitioning tool 5, the power line cable 17 and the communication cable 18 are respectively laid in the upper space portion of the partitioning tool 5, and then the main body 2 is covered with the lid 4. When the upper end opening is closed, the laying of cables, pipes, and the like is completed.

Here, as shown by imaginary diagrams in FIGS. 1 and 2, when a reinforcing rib 20 is provided at the center of the upper surface of the partitioning tool 5 so as to abut against the back surface of the lid 4, this reinforcing rib is provided. 20
Can not only reinforce the partitioning tool 5 but also improve the rigidity of the lid 4 by supporting the lid 4 from the lower surface thereof, and can be used as an operation unit when the partitioning tool 5 is attached and detached. In the above-described embodiment, the installation portion 6 for the cable or the tube is formed in a semicircular shape or a U shape at the center of the bottom portion. However, the shape is not limited to such a shape, and may be formed in a semicircular shape or a V shape. Needless to say, the installation portion 6 can be used not only for installing a cable or a tube material but also for running rainwater, which is an original use of the gutter.

[0014]

As described above, in the gutter according to the present invention, at least the main part of the main body, the lid and the partition forming the gutter is pressed by a mold using cement as a raw material. Since it is formed by molding, the density of the concrete is increased by this press molding, and the strength is greatly improved. This makes it possible to reduce the thickness of the concrete, to reduce the size and weight, and to easily perform the laying work, thereby shortening the construction period and reducing the laying cost.

In the case of laying cables and pipes, the gutters are laid at the time of zoning. Therefore, it is only necessary to install the cables and pipes in the gutters. I can do it. Accordingly, there is an advantage that the laying cost can be reduced, and that traffic interruption during the laying operation can be shortened to reduce traffic congestion as much as possible.
