[0002]

2. Description of the Related Art Japanese Patent No. 2992263 discloses a technique in which a support is erected on a frame whose upper surface is inclined inward and outward. In the technology disclosed in this publication, the lower end of the support is inclined along the inclination of the upper surface of the skeleton, and the lower end of the reinforcing member provided inside the support is also inclined along the inclination of the upper surface of the skeleton. In addition, the entire lower edge of the reinforcing member is in contact with the upper surface of the skeleton.

[0003]

However, in the above-mentioned prior art, the lower end of the support and the lower end of the reinforcing member are aligned so as to be inclined at the same inclination angle as the inclination of the upper surface of the frame. It is necessary to accurately cut the lower end of the body so that the inclination angle is the same as the inclination angle of the upper surface of the body.

Accordingly, an object of the present invention is to provide a column device which does not require high-precision cutting and is easy to construct.

[0005]

SUMMARY OF THE INVENTION According to the present invention, there is provided a support member provided on an upper surface of a frame, a reinforcing member fitted inside the column, and a reinforcing member inserted vertically and fixed at a lower end portion to the upper surface of the frame. A bolt that fixes the support to the top of the skeleton, a tapping screw that stops the support and the reinforcing member from outside the support, and a cover that hides the gap between the bottom of the support and the top of the skeleton. The lower end of the member is inclined, and the column can freely change the vertical position with respect to the auxiliary member.The lower end of the column contacts only the upper position of the upper surface of the sloping body and the lowermost end of the reinforcing member is positioned at the lower position of the upper surface of the skeleton. And the vertical supporting column and the auxiliary member are fixed with a tapping screw.

In the present invention, a bolt is inserted from above to below the reinforcing member, and the lower end of the bolt is fixed to the upper surface of the frame. Provide a support so that the reinforcing member fits inside the support, screw the tapping screw from the outside of the support to stop the support and the reinforcing member, so as to cover the gap between the lower end of the support and the skeleton, Attach the cover around the lower end of the column. The upper surface of the skeleton is inclined, and when the column is erected vertically on the upper surface of the skeleton, the lower end of the column is substantially horizontal. Therefore, the lower end of the column contacts the upper surface of the skeleton only at a position above the upper surface of the skeleton. The inclined lowermost end of the reinforcing member abuts only on a position below the upper surface of the skeleton. Therefore, the vertical support and the vertical reinforcing member are fixed with tapping screws, and on the inclined upper surface of the frame, the lower end of the support comes in contact with the upper position,
In the lower position, the lowermost end of the inclined lower end of the reinforcing member is in contact with the lower end, and in this state, the reinforcing member is fixed to the skeleton by bolts, so that the column can be stably erected. In addition, since it is not necessary to cut the lower end of the support or the lower end of the reinforcing member in accordance with the inclination angle of the upper surface of the skeleton, accurate cutting is not required and construction is easy. Moreover, when the inclination of the upper surface of the skeleton is large, the lowermost end of the reinforcing member with respect to the lower end of the column is adjusted so as to protrude downward more,
When the inclination of the upper surface of the skeleton is small, the amount of the lowermost end of the reinforcing member protruding from the lower end of the column is adjusted to be small, so that the construction according to the inclination angle of the upper surface of the skeleton is easy. In addition, at the lower end of the support, the gap formed between the support and the upper surface of the support is covered with a cover, and is invisible from the outside, so that the appearance is good.

[0007]

Embodiments of the present invention will be described below. FIG. 1 is a longitudinal section of a column device according to an embodiment of the present invention, FIG. 2 is a sectional view taken along line AA of FIG.
FIG. 2 is a longitudinal sectional view when the height of the column shown in FIG. 1 is reduced. The column device 1 according to the present embodiment is a column of a handrail, and stands upright on a concrete frame upper surface 2. The support device 1 includes a support 3, a reinforcing member 5, and a cover 7.
, A bolt 9 and a tapping screw 11. The skeleton upper surface 2 is inclined such that the outer side is higher than the inner side, and the column device 1 is erected on such an inclined surface. The support 3 is an aluminum extruded profile having a rectangular cross section. Upper end 3a and lower end 3 of this support 3
b is substantially horizontal, and at the lower end 3b of the column, only the outer end 17 is in contact with the upper surface 2 of the skeleton, and the inner end 18 is spaced apart from the upper surface 2 of the skeleton. Reinforcing member 5
Is an extruded shape member made of aluminum, which is fitted inside the column 3, and a fitting portion 19 fitted inside the column 3.
And a bolt mounting portion 21 are provided. The bolt mounting portion 21 includes a central hole 23 having a small hole diameter, and both side holes 25a and 25b having a large hole provided on both sides of the center hole 23. In FIG. Bolts 9, 9 are inserted through 25b. The lower end 33 of the reinforcing member 5 is inclined such that the outer edge 35 is higher than the inner edge 37, and is inclined at a larger inclination angle than the top surface 2 of the skeleton. That is, FIG.
In the reinforcing member 5, only the inner edge 37 of the skeleton upper surface 2 in the inward and outward directions contacts the inclined upper position of the skeleton upper surface 2 as shown in FIG. The lower ends of the bolts 9, 9 are inserted through bolt insertion holes 29 provided in the upper surface 2 of the skeleton, and are fixed to the skeleton 2 a with a filler 31. The filler 31 is, for example, an adhesive. The tapping screw 11 fixes the support 3 and the reinforcing member 5 at two positions, that is, the upper and lower positions of the reinforcing member 5. The tapping screw 11 is screwed from the outside of the support 3. The cover 7 is provided on the outer periphery of the lower end of the support 3, and covers the gap S generated between the lower end of the support 3 and the upper surface 2 of the skeleton. The upper cover 43 is provided on the upper edge 3 a of the support 3.

[0010] Next, a method of installing the column device 1 according to the present embodiment will be described. The lower end 33 of the reinforcing member 5 cut at an inclination angle larger than the inclination of the upper surface 2 of the skeleton is set upright on the upper surface 2 of the skeleton. In this case, at the lower end 33 of the reinforcing member 5, only the lowermost end 37 abuts at a position below the inclined frame upper surface 2. Since the reinforcing member 5 is made of aluminum, the cutting of the reinforcing member 5 can be easily performed. Further, since the inclination of the lower end 33 of the reinforcing member 5 does not need to be adjusted to the upper surface of the skeleton, and precision is not required, the cutting can be easily performed. Next, in the reinforcing member 5, of the three holes 23, 25 a, and 25 b in the bolt attachment portion 21, two outer holes 25
The lower end 9a of the bolt 9 is disposed in the bolt insertion hole 29 provided in the upper surface 2 of the skeleton, the filler 31 is filled in the bolt insertion hole 29, and the reinforcing member 5 is attached to the skeleton 25b. 2a. Subsequently, the reinforcing member 5 is fitted inside the supporting column 3 such that the supporting column 3 covers the outside of the reinforcing member 5. The lower end 3b of the column 3 is substantially horizontal, while the upper surface 2a of the skeleton is inclined.
The lower end portion 3b abuts only on the position above “a”. Next, the column 3 and the reinforcing member 5 are stopped from outside the column 3 by tapping screws 11. Thereby, the reinforcing member 5 and the column 3 are fixed. Since both the support 3 and the reinforcing member 5 are made of aluminum, the tapping screw 11 can be used, and the construction is easy. The reinforcing member 5 and the support 3 are fixed to each other, and the outer end 17 of the lower end 3 b of the support 3 abuts only on the upper position 22 of the upper surface 2 of the skeleton.
Since the lowermost end 37 of the reinforcing member 5 abuts at 0 and abuts at two places as a whole, the column 3 is stable. In addition, when the inclination of the skeleton upper surface 2 is large, the lowermost end 37 of the reinforcing member 25 with respect to the lower end 3b of the column 3 is adjusted to increase downward. By adjusting the amount of extension of the lowermost end 37 of the reinforcing member 25 with respect to the lower end 3b to be small, it is possible to easily carry out the construction according to the inclination angle of the skeleton upper surface 2. Next, the cover 7 is attached to the outer periphery of the lower end 3b of the column 3 to hide the gap S between the lower end 3b of the column 3 and the upper surface 2 of the frame. In this embodiment, since both the support 3 and the reinforcing member 5 are made of aluminum, there is no rust and processing at the construction site such as cutting is easy. On the other hand, as shown in FIG. 3, when it is desired to lower the height of the column 3, the same column 3 and reinforcing member 5 as described above are used, but the column 3 is cut at its lower end to an appropriate length. However, the cutting can be easily performed because the cylindrical column 3 is merely cut in a substantially horizontal direction. On the other hand, the lower end 33 of the reinforcing member 5 is also cut obliquely at a position of a predetermined size.
Also in the case of the reinforcing member 5, the cutting can be easily performed because it is merely cut diagonally without adjusting to the inclination of the skeleton upper surface 2. When the lengths of the support 3 and the reinforcing member 5 are adjusted in this manner, the support 3 is erected on the upper surface 2 of the skeleton in the same manner as the support device 1 shown in FIG. 1 described above. 5 is attached to the central hole 23 and fixed to the frame 2a. The bolt mounting portion 21 has two outer holes 25a and 25b and the center hole 2
3, a total of three holes are provided, so that when the height of the column 3 is high, the reinforcing member 5 is connected to the outer holes 25a and 25
b, it can be fixed with two bolts 9, 9 and when the height of the column 3 is low, one bolt 9 is formed using the central hole 23.
, And the number of bolts 9 to be used can be changed as necessary. In addition, even when the construction is performed while changing the height of the column 3,
When the support 3 is installed, it is not necessary to cut the lower end 3b of the support 3 and the lower end 33 of the reinforcing member 5 with high precision in accordance with the inclination of the upper surface 2 of the skeleton.

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, the materials of the column 3 and the reinforcing member 5 are not particularly limited, and both are not limited to aluminum. Any number of tapping screws 11 for stopping the support 3 and the reinforcing member 5 may be used.
May be hidden by the cover 7. Prop device 1
Is not limited to a handrail post, but may be a post such as a fence, and the use is not limited. The bolt 9 is not limited to the one with a head, and may be a nut in which a nut is screwed in place of the head. Further, the bolt 9 may be a bolt having only a shaft portion without a head, and may be attached to a lower portion of the reinforcing member 5. In this case, the shaft portion may be entirely formed with a screw, or the screw is formed only in the lower half, and the upper half where the screw is not formed is fixed to the reinforcing member 5 with an adhesive. It may be.

According to the present invention, the lower end of the strut abuts on the upper surface of the skeleton on the outer side in the inward and outward directions of the skeleton, and the lower end of the reinforcing member abuts on the upper surface of the skeleton on the inner side. The pillar can be stably erected on the upper surface of the skeleton. Since it is not necessary to cut the lower end of the support and the lower end of the reinforcing member in accordance with the inclination of the upper surface of the skeleton, accurate cutting is not required and the construction is easy. Since the column is provided so that the vertical position with respect to the reinforcing member can be freely changed, it can be easily constructed regardless of the inclination angle of the upper surface of the skeleton. At the lower end of the support, the gap formed between the support and the upper surface of the support is covered with a cover and is invisible from the outside, so that the appearance is good.
