BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a block for a foundation which is built when an illumination lamp is erected on a road or a park.

[0002]

2. Description of the Related Art On a road or in a park or the like, an illuminating lamp is connected to an anchor member protruding from a block-shaped foundation made of concrete placed in the ground and is erected on the foundation.
At that time, for the foundation work, a cylindrical formwork is framed in the embedding recess with a circular cross-section that is drilled in the ground at the construction site, and the gap between the formwork and the embedding recess is made of sand or the like. While the concrete material is poured into the formwork in the tightened state, most of the anchor members, except for a part, are embedded in the concrete material, and they are constructed in a sequence of waiting for the concrete material to dry. .

[0003]

By the way, in the above-mentioned prior art, a mold having a cylindrical cross section integrated with the basic block body is formed on the inner peripheral surface of the circular tubular filling layer filled between the mold and the recess for embedding. It has a cross-sectional structure in which surface contact is made so that sliding contact is possible. Therefore, the foundation block body easily rotates between the foundation block and the packed bed, and strong fixation cannot be expected, and since it is wet construction, it causes problems such as complication of on-site construction. It is also possible to propose that the foundation block body in which the anchor member is embedded is formed of precast concrete, is dropped into the recess for embedding, and the periphery is closed with a filler such as sand to form the foundation.
However, since the cross section is circular, it is difficult to position the anchor member when setting the anchor member in the recess for embedding. Since the sliding contact is formed with respect to the recess for embedding in the same manner as described above, firm fixation is not expected. In addition to the problem, stacking is not possible during maintenance and management. Danger of rolling during transportation. Precision molding cannot be obtained by horizontal casting (molding with the mold oriented horizontally). Cause problems such as.

The present invention has been made in view of the above conventional circumstances, and an object thereof is to provide a basic block for an illumination lamp that solves the above problems, and its technical problem is to provide: Due to the peculiarity of the cross-sectional shape of the foundation block body used for the foundation constructed by the dry method, it is firmly fixed to the recess for embedding, the anchor member can be easily set in the specified direction, and stacking is possible during inventory management. , To prevent rolling during transportation, and to satisfy horizontal molding at the factory all together.

[0005]

[Means for Solving the Problems] The technical means taken to achieve the above-mentioned object is to make a base block body made of precast concrete and having a prismatic cross-section form a connecting portion for connection with an illuminating lamp from a top surface. The gist is that the anchor member is embedded and fixed, and a cable lead-in path that connects the side surface and the top surface is formed in the base block body.

[0006]

According to the above technical means, there are the following actions.
Each of the polygonal ridges of the base block body engages with the inner peripheral surface of the recess for embedding. A straight line of the same polygonal surface can be used as a parallel or right-angled alignment surface for the curb of the road. In addition, a cable routed underground is introduced from the foundation block body and connected to the lamp.

[0007]

According to the basic block for an illumination lamp of the present invention, each ridge portion of the outer surface of the basic block body made of precast concrete is engaged with the inner peripheral surface of the recess for embedding. Since the engaging relationship with which the resistance is large and which is hard to rotate is configured, firm fixing to the recess for embedding can be expected. Moreover, when inserting and setting in the recess for embedding, the desired straight surface of the outer surface can be used as a positioning surface parallel or perpendicular to other locations (curbstones of roads, etc.),
It is very easy to place the anchor member in the proper position. Furthermore, the construction period can be expected to be significantly shortened compared to the wet method, which is very effective in shortening traffic regulation.
In addition, the basic block bodies can be stacked due to the shape of the outer surface of the basic block body, and since they do not roll during transportation, the space for inventory management is not wastefully occupied, and a large number of blocks can be safely stored together. Can be carried to the construction site. In addition, although the foundation block body has a toll of about 2 m, it is accurate by horizontal casting (casting concrete material with the molding die oriented horizontally) due to the peculiarity of the prismatic shape. It is possible to obtain products that have a mold, and it is possible to give flexibility to mold even in a factory where the molding space cannot be secured in the height direction, and it does not force you to work at a high place like vertical casting, so it is safe. Can be molded. Furthermore, it is possible to easily lead out the cables centrally wired in the ground to the top surface of the block through the cable lead-in path opened from the side surface to the top surface of the block body, and The length can be easily adjusted because the cable can freely move in the cable lead-in path. Therefore, when the cable is connected to the lamp, the protrusion length can be easily adjusted and the connection work can be easily performed.
