Description of the Related Art For example, Japanese Utility Model Laid-Open Publication No. 4-48367 discloses a partition-type fence for inclined ground, in which an upper chord material fixing portion in which an upper chord material of a fence body is fixed is horizontally fixed to an upper fixing portion of a support. The lower chord material fixing part which fixed the lower chord material of the fence body to the lower fixing part of the support column is also connected rotatably by the horizontal axis, and the fence body is vertically Disclosed is a configuration that is mounted to be inclined in a direction. However, according to the technique disclosed in the above-mentioned publication, a gap is formed between the support and the fence body. When closing such a gap, it is conceivable to separately provide a gap closing member between the column and the fence body.However, in a fence constructed on an inclined ground, the fixed positions of the upper fixed portion and the lower fixed portion of the column are left and right. Since they are different, the gap closing member needs to be attached at the construction site in accordance with the fixing position of the upper and lower fixing portions, and there is a problem that the construction takes time. Accordingly, an object of the present invention is to provide a fence which can close a gap between a support post and a fence body and can be easily constructed on a slope. [0005] The invention according to claim 1 comprises a right fence body, a left fence body, and a column connecting the right fence body and the left fence body. At least one fence body of the left fence body is vertically inclined and connected to a support, and the support is

And left and right gap closing members provided so as to be movable in the vertical direction, and the left and right gap closing members close the gap between the column and the fence body. According to the first aspect of the present invention, when constructing a fence on a slope, a support is erected on the ground, and left and right fences are attached to the support. Attachment of the fence body to the support is performed by fixing the positions of the upper fixed part and the lower fixed part by adjusting the vertical position of the upper fixed part and the lower fixed part of the support according to the mounting position of the fence body on the slope. The gap closing member moves following the vertical movement of the vertical fixing portion. Next, after the upper chord fixing portion and the upper fixing portion are rotated and positioned with respect to the horizontal axis, the upper chord of one of the fence bodies is attached to the upper chord fixing portion, and at the same time, the lower fixing portion also has After the positions of the lower fixing portion and the lower chord material fixing portion in the rotation direction are determined, the lower chord material of the fence body is attached to the lower chord material fixing portion. Then, the upper chord fixing portion and the upper fixing portion are fixed, and the lower chord fixing portion and the lower fixing portion are fixed. According to the fence according to the present invention, since the gap closing member is provided between the support and the fence body, the gap between the support and the fence body can be closed and closed. Since the gap closing member follows the vertical movement of the vertical fixing portion, there is no need to adjust the mounting position of the gap closing member, so that the construction is easy. By similarly connecting the other fence body to the support, the gap closing member closes the gap between the support and the fence body. Embodiments of the present invention will be described below in detail with reference to the accompanying drawings. FIG. 1 is a front view of a fence according to an embodiment of the present invention, and FIG.
FIG. 3 is a longitudinal sectional view of the fence body shown in FIG. The fence 1 according to the present embodiment is a blind fence that blocks a view from the front side to the rear side of the fence, and is installed on the inclined ground 2. The fence 1 includes a support 3 and right and left fence bodies 5 attached to the support 3.
Note that, in the embodiment described below, the right and left fence bodies 5 and the left and right configurations of the columns 3 are substantially the same.
The same reference numerals are given to the same portions on the left and right of the support column, and the detailed description of those portions is omitted. In the present embodiment, the vertical member 11 is attached between the upper chord member 7 and the lower chord member 9 in the fence body 5, but the vertical member 11 is attached such that a part of the left and right sides is overlapped in the front-rear direction. This is a so-called blind fence that blocks the view from the front side to the back side. The support 3 has upper fixing portions 13 on the left and right sides, respectively.
, An upper chord fixing portion 15, a lower fixing portion 17, a lower chord fixing portion 19, and a gap closing member 21. The upper fixing portion 13 and the upper chord material fixing portion 15 are rotatably connected by a horizontal shaft portion 23. The support 3 has a head 2 of a bolt 25
An engagement groove 27 that engages with the upper fixing portion 13 is formed in the vertical direction at an arbitrary position in the vertical direction by the bolt 25 and the nut 29. One end 15 a of the upper chord fixing portion 15 is inserted into the upper chord 7 of the fence body 5 and fixed by screws 31. Lower fixing part 17
The lower chord fixing portion 19 is rotatably connected to the lower chord material fixing portion 19 by a horizontal shaft portion 24. The lower fixing portion 17 is provided with the engagement groove 27 described above.
The lower fixing portion 17 is fixed to the column 3 at an arbitrary position in the vertical direction with a bolt 37 and a nut 39 having a head 37a engaged with the column 3. In addition, lower chord material fixing section 1
9 has one end 19 a inserted into the lower chord member 7 of the fence body 5 and fixed by screws 32. When the fence body 5 is attached to the column 3 at an angle, the vertical members 1 of the fence body 5
1 is rotatably connected to the upper chord material 7 and the lower chord material 9 so that the vertical member 11 is vertical, but since the upper chord material 7 and the lower chord material 9 are inclined, the fence body 5 is parallel as a whole when viewed from the front. It becomes a quadrilateral shape. The gap closing member 21 has an upper portion fixed to the upper fixing portion 13 by screws 41 and a lower portion fixed to the lower fixing portion 17 by screws 43. Since the gap closing member 21 is thus fixed to the upper fixing portion 13 and the lower fixing portion 17, it moves following the vertical movement of the upper fixing portion 13 and the lower fixing portion 17. The gap closing member 21 is disposed between the vertical member 11 and the column 3 on the column 3 side of the fence body 5, and the gap closing member 21 and the vertical member 11 are arranged in the front-rear direction (the front side and the back side of the fence). And the direction). Next, the construction method and operation of the fence according to the embodiment of the present invention will be described. The support 3 is erected on the slope and the fences 5 are attached to the left and right of the support 13,
First, the fence body 5 is mounted on the upper fixing portion 13 and the lower fixing portion 1 of the column 3 in accordance with the mounting position of the fence body 5.
Adjust the vertical position with 7. The upper fixing portion 13 is fixed by moving the head 25a of the bolt 25 along the locking groove 27 and screwing the nut 29 at a predetermined position. Similarly, in the lower fixing portion 17, a nut is screwed into the bolt 35 having the head 35 a engaged with the locking groove 27, and the lower fixing portion 17 is fixed to the column 3. Since the gap closing member 21 is fixed to the upper fixing portion 13 and the lower fixing portion 17 by the screws 41 and 43, the gap closing member 21 follows the vertical movement of the upper fixing portion 13 and the lower fixing portion 17. Is moved up and down, and the gap closing member 21 is also fixed at that position by fixing the upper fixing portion 13 and the lower fixing portion 17. Next, after the upper chord material fixing portion 15 is rotated and positioned about the horizontal axis 23 with respect to the upper fixing portion 13, the lower chord material fixing portion 19 is similarly moved to the horizontal axis 35 with respect to the lower fixing portion 17. Rotate around the center for positioning. And the upper chord material 7 of the fence body 5
The lower chord fixing part 19 is inserted into the lower chord 9 of the fence body 5 and fixed with the screw 41. The other fence body 5 is attached in the same manner, and the fence body 5 is fixed to the left and right of the column 3 to construct the fence 1. Since the gap closing member 21 is provided between the fence body 5 and the support 3, the gap between the fence body 5 and the support 3 can be closed. In particular, in the blindfold fence according to the present embodiment,
By closing the gap between the fence body 5 and the support 3, the entire fence 1 can be blindfolded without leakage. In addition, since the gap closing member 21 is attached to the column 3, there is no need to attach it at the construction site, and it is possible to reduce the number of parts at the time of transport to the construction site, and it is not necessary to attach it at the construction site. Can be reduced. Further, the gap closing member 2
1 moves following the vertical positioning of the upper fixing part 13 and the lower fixing part 17, so that the fence body 5 and the support 3 are positioned by aligning the upper fixing part 13 and the lower fixing part 17. Can be automatically placed in the gap between. Since the upper fixing portion 13 and the lower fixing portion 17 provided on the left and right of the column 3 can be moved up and down, the vertical position of the left and right fence members 5 with respect to the column 3 can be set arbitrarily. The members 7, 7 and the lower chord members 9, 9 can be easily set in a straight line. The present invention is not limited to the above embodiment,
Various modifications can be made without departing from the spirit of the present invention.
For example, both the left and right fence bodies 5 are not limited to be inclined with respect to the support 3, and only one of them may be inclined with respect to the support 3. By moving the bolts 25 and 35 along the engagement grooves 27 formed in the up and down direction of the support 3, the vertical position of the upper fixing portion 13 and the lower fixing portion 17 is not limited to being moved. It is sufficient that the mounting position of the lower fixing part 17 and the lower fixing part 17 can be changed in the vertical direction. The left and right fence bodies 5 are not limited to the vertical members 11,
A cross member may be arranged, and the shape of the fence body 5 is not limited. Furthermore, not only the blind fence body whose view is blocked by the fence surface but also a gap may be formed between adjacent vertical members or horizontal members in the fence member 5. According to the first aspect of the present invention, since the column is provided with the gap closing member for closing the gap between the column and the fence, the space between the column and the fence can be blinded. . Since the gap closing member follows the vertical movement of the upper and lower fixing portions, it is not necessary to adjust or position the mounting position of the gap closing member only by aligning the upper and lower fixing portions.
