Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elbow crucible mounting structure.

[0002]

2. Description of the Related Art Conventionally, when mounting an elbow crucible necessary for mounting a gate, two bolts are used because one bolt rotates.

[0003]

However, since there is only one bolt for fixing the concrete plate to the support pillar, new holes are formed in the support pillar and the concrete board in addition to the holes for fixing the concrete board, and the holes in the concrete board are There is a problem in that it takes time and effort to bury the nuts.

Therefore, an object of the present invention is to provide an elbow crucible mounting structure capable of improving workability.

[0005]

According to the elbow crucible mounting structure of the present invention, in the elbow crucible mounting structure in which the elbow crucible mounting piece is interposed between the column and the concrete plate, the column, the elbow crucible mounting piece, and The concrete plate is fixed with a single bolt, and a pair of rotation stop plates are fixed to the columns above and below the mounting piece.

[0006]

According to the structure of the present invention, since the mounting piece of the elbow crucible is positioned by the pair of rotation stopping plates, it is possible to fix the elbow crucible with one bolt. Therefore, since the elbow crucible can be fixed at the same time with the single bolt used to fix the concrete plate, the workability can be improved.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An elbow crucible mounting structure according to a first embodiment of the present invention will be described with reference to FIGS. Between the pillar 1 and the concrete plate 2 which constitute the gate fence, an elbow crucible 3 necessary for attaching a gate (not shown) is attached.

That is, the support column 1 is provided with a plurality of bolt insertion holes 1a, which are made of channel steel and arranged in a line on the web, so that the concrete plate 2 can be fixed by bolts. Further, a pair of rotation stopping plates 7 and 7 are fixed by welding substantially parallel to the upper and lower sides of the predetermined hole 1a. In this case, the rotation stop plate 7 uses an iron plate having a thickness of about 9 mm. Further, although the width dimension of the rotation stop plate 7 is made shorter than the width dimension of the column 1 in the same figure, they may be the same. An embedded nut 4 is embedded in the side end surface of the concrete plate 2. When embedding the embedding nut 4, a hole is formed in the side end surface of the concrete plate 2, the embedding nut 4 is inserted, and mortar cement is filled and fixed. In this case, the hole may be an existing hole provided from both end faces in the longitudinal direction to reduce the weight. The elbow crucible 3 includes a tubular portion 8 that receives the pivot shaft of the gate and a plate-shaped mounting piece 9. The mounting piece 9 is provided with one bolt insertion hole 9a and has a shape that can be fitted between the pair of rotation stopping plates 7 and 7. In addition, FIG. 4 is a front view of the gate fence,
A plate 32 is attached to the lower end of the column 1 and fixed to an anchor bolt embedded in the foundation (not shown). The lower ends of the pair of columns 1, 1 are connected by a column connecting member 33.

At the time of construction, the attachment piece 9 of the elbow crucible 3 is fitted between the pair of rotation stopping plates 7 and 7, and the bolt 6 is inserted into the bolt insertion holes 1a and 9 as shown in FIGS.
It is passed through a and screwed into the embedded nut 4. This allows
The pillar 1, the elbow crucible 3 and the concrete board 2 are integrally fixed. In this embodiment, since the mounting piece 9 of the elbow crucible 3 is positioned by the pair of rotation stopping plates 7 and 7, it is possible to fix the elbow crucible with one bolt 6. Therefore, the elbow crucible 3 can be fixed at the same time with the single bolt 6 used to fix the concrete plate 2, which saves the labor of construction.

A second embodiment will be described with reference to FIG.
In this embodiment, an adjusting nut 5 is provided so that the concrete plate 2 can be adjusted left and right. The adjustment nut 5 is the support 1
And the concrete plate 2 are screwed to the bolt 6. In this case, the attachment piece 29 of the elbow crucible 23 is attached while being sandwiched between the concrete plate 2 and the adjusting nut 5. A cover 11 having a tongue piece 12 interposed between the pillar 1 and the concrete board 2 is attached to the pillar 1. Therefore, the width of the rotation stop plate 7 should be the same as that of the column 1.
The width of the tongue piece 12 is smaller than the width of the column 1 at both ends of the web of the column 1 (see FIG. 1).
The elbow crucible 23 is substantially L-shaped, and is composed of two members that are separable from each other and are connected to the tubular portion 28 and the mounting piece 29 by bolts 30. Other structural effects are similar to those of the first embodiment.

[0011]

According to the elbow crucible mounting structure of the present invention,
Since the pair of rotation stop plates position the attachment piece of the elbow crucible, it is possible to fix the elbow crucible with one bolt. Therefore, the elbow crucible can be fixed at the same time with one bolt used to fix the concrete plate, which improves the workability.
