DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fence.

[0002]

2. Description of the Related Art Conventionally, in a fence constructed by arranging a concrete plate between a pair of columns, a hole is directly formed in the concrete plate and a nut is buried in the hole to fix the bolt between the concrete plate and the column. Was able to do.

[0003]

However, since a step of making a hole in a concrete plate is required in a factory or a site, the operation is troublesome. In addition, the processing accuracy of drilling holes in concrete plates varies.
If the processing accuracy is poor, the concrete plate may not fit between the pair of columns, and even if it fits, there is a problem that the left and right shifts are large and the finish is deteriorated.

Accordingly, an object of the present invention is to provide a fence with improved workability and a good finish.

[0005]

SUMMARY OF THE INVENTION A fence according to the present invention comprises a pair of columns which are erected at a predetermined interval, and a concrete which is disposed between the columns and has an existing hole from a side end face in a longitudinal direction. Board, and a buried nut is buried in the hole, and an adjusting nut is screwed into a bolt penetrating the support so as to be interposed between the support and the concrete plate, and a tip end of the bolt is connected to the buried nut. It is characterized by being screwed.

[0006]

According to the structure of the present invention, the embedded nut is buried using the existing hole for reducing the weight of the concrete plate, so that there is no need for the conventional process of making a hole in the concrete plate, and the production is reduced. The workability or workability is improved. In addition, since the existing hole has higher accuracy than the hole processed after the concrete plate is hardened, the concrete plate fits in a predetermined position between the pair of columns, and the finish is good. Further, by operating the bolt and the adjusting nut, the gap between the concrete plate and the column can be adjusted to be uniform on both sides, and the concrete plate is firmly fixed to the column via the bolt.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A fence according to an embodiment of the present invention will be described with reference to FIGS. This wall shows the case of a gate wall. Reference numerals 1 ... stand up at predetermined intervals,
A plurality of concrete plates 2 are arranged between a pair of columns 1, 1 facing each other.

As shown in FIG. 4, the column 1 is formed of a channel steel except for the corner portion, and a bolt insertion hole is provided in an opposing web. An adjusting nut 5 is screwed into the bolt 6 inserted into the bolt insertion hole so as to be interposed between the column 1 and the concrete plate 2. The column 1 'at the corner is made of L-shaped steel, and the column 1' and the concrete plate 2 are similarly fixed with bolts 6. Further, the adjustment nut 5 is not provided in the corner portion but may be provided.

[0009] As shown in FIG.
It has a plurality of existing holes 3 from the side end face to the longitudinal direction for weight reduction. An embedded nut 4 is buried in all of the holes 3 or an appropriate hole 3 and filled with mortar cement to be fixed. As shown in FIG. 6, a sign post 7 is incorporated in a predetermined concrete plate 2. The wiring 8 to the sign post 7 is wired from the inside of the column 1 to the existing hole 3 as shown by a dashed line. 9 is a gate light wiring. In FIGS. 5 to 7, ● indicates the bolt fixing position, and 10 indicates the level of the upper surface of the foundation. Further, the base plate 11 of the column 1 is fixed to anchor bolts (not shown) embedded in the foundation. In addition, a strut connecting member 12 is interposed between the lower ends of the pair of struts 1, 1 to improve the strength of the pair of struts 1, 1 and also serves as a spacing function.

At the time of construction, a concrete plate 2 is arranged between a pair of columns 1, 1 facing each other. The adjusting nut 5 is screwed into the bolt 6 that has passed through the column 1 through the bolt insertion hole, and the tip of the bolt 6 is screwed into the embedded nut 4 embedded in the concrete plate 2. This operation is similarly performed on both side edges of the concrete plate 2. At this time, as shown in FIG. 2, the bolt 6 and the adjustment nut 5 are operated and adjusted so that the gap between the concrete plate 2 and the column 1 is equal on both sides. Repeat the above work,
Concrete plates 2 are sequentially stacked from the bottom to complete the gate wall. The work of embedding the embedding nut 4 in the existing hole 3 may be performed at a factory or on site.

In this embodiment, the existing nut 3 for reducing the weight is used in the concrete plate 2 to embed the nut 4.
Is embedded, so that there is no need for a processing step for making a hole in the concrete plate 2 as in the prior art, thereby improving productivity or workability. In addition, since the existing hole 3 has higher accuracy than a hole processed after the concrete plate 2 is hardened, the concrete plate 2 fits in a predetermined position between the pair of pillars 1 and 1, and the finish is good. . By operating the bolt 6 and the adjusting nut 5, the concrete plate 2 and the support 1
The concrete plate 2 is firmly fixed to the column 1 via the bolt 6 by the adjusting nut 5. In the embodiment, the gate wall is used, but another wall may be used.

[0012]

According to the fence of the present invention, since the embedded nut is buried using the existing hole for reducing the weight of the concrete plate, there is no need for the conventional process of making a hole in the concrete plate. , Productivity or workability is improved. In addition, since the existing hole has higher accuracy than the hole processed after the concrete plate is hardened, the concrete plate fits in a predetermined position between the pair of columns, and the finish is good. Further, by operating the bolt and the adjusting nut, the gap between the concrete plate and the column can be adjusted to be uniform on both sides, and the concrete plate is firmly fixed to the column via the bolt.
