Referring to FIGS. 1 to 3, the pillar fixing device of the present embodiment includes a base plate 10, a fixing cap 20, an adjustment bolt 30, and a tightening block 40.

Here, the overall flat cross-sectional shape of the base plate 10 and the fixing cap 20 may be formed in a circular, elliptical or various polygonal shapes according to the cross-sectional shape of the column or beam to be fixed.

In the present embodiment, the pillar fixing device 1 exemplifies a pillar fixing device for fixing the lower end of the pillar 100 having a hollow circular pipe shape.

However, the present invention is not necessarily limited thereto, and it is natural that the present invention may be variously modified according to the cross-sectional shape of the pillar 100 to be fixed as described above.

Therefore, the base plate 10 is comprised including the support plate part 11 of the disk shape, and the fitting protrusion 12 protruding in the cylindrical shape upward from the center part of the support plate part 11. As shown in FIG.

The support plate part 11 may be mounted on a concrete base installed to fix the pillar 100, and may be fastened by anchor bolts or the like integrally installed on the concrete base.

In addition, first fastening holes 15 for fastening and fixing the fixing cap 20 using fastening bolts and fastening nuts 51 and 52 are formed along the edges of the support plate part 11.

The fitting protrusion 12 is formed to protrude so as to fit into the lower end of the pillar 100 inserted through the insertion hole 23 formed in the fixing cap 20. That is, the fitting protrusion 12 is fixed to the fixing position of the pillar 100 into which the insertion hole 23 of the fixing cap 20 is inserted before tightening the outer circumferential surface of the pillar 100 with the tightening block 40. Make it rough.

Fixing cap 20 is configured to include a body portion 21, the flange portion 22, and the adjusting end (23).

The trunk portion 21 has a substantially cylindrical shape, and on the inner circumference of the trunk portion 21, six pairs of guide rails for vertically conveying the tightening blocks 40 in the vertical direction by the operation of the adjusting bolt 30 ( 28) is formed.

The guide rail 28 is formed to be inclined in the shape of a wedge in which the width of the radial direction becomes wider toward the upper side of the body portion 21, and gradually increases as the tightening blocks 40 are moved upward by the manipulation of the adjusting bolt 30. Guide them in the direction of the center of the circle.

On the other hand, the guide rails 28 are formed to protrude in the radial direction toward the circle center point on the body section 21 flat cross section of the fixing cap 20, respectively.

The flange portion 22 is formed to protrude from the lower end of the body portion 21 with a predetermined outside width along the circumferential direction.

On the other hand, the flange portion 22 is a portion protruding to fasten using the fastening bolt 51 and the fastening nut 52 to raise the fixing cap 20 on the base plate 10, the first fastening hole A plurality of second fastening holes 25 corresponding to the field 15 is formed through the circumferential direction.

And, the adjusting end 23 is formed to protrude from the upper end of the body portion 21 with a predetermined width along the inner circumferential direction.

The adjusting end 23 has an inner end bent downward to form the above-described insertion hole 23, and through the insertion hole 23 into the fixed cap 20 fastened and fixed to the upper side of the base plate 10 through the pillar ( The lower end of 100) is inserted.

In addition, the adjusting end 23 is formed with a first through hole 26 for fastening to the fastening block 40 fixed to be transported along the guide rail 28 through the adjusting bolt 30. Here, the first through hole 26 is formed at a position through which the adjustment bolt 30 passes between the pair of guide rails 28.

In addition, the adjusting end 23 is recessed around the first through hole 26 to form a locking groove 27, and the locking groove 27 allows the head of the protruding adjustment bolt 30 to be locked. Make the appearance more beautiful.

4 is an exploded perspective view of the tightening block of FIG. 2, and FIG. 5 is a cross-sectional view taken along the line VV of FIG. 1.

Referring to FIGS. 4 and 5, the tightening block 40 includes a block body portion 41, a transfer nut 42, and a guide bracket 43.

The block body portion 41 includes two side plates 41a and upper, lower plates 41b and 41c coupled to the upper and lower sides between the side plates 41a, and the side plates 41a, upper, It is coupled between the lower plates (41b, 41c) and the rear side is closed and the inner receiving space includes a "c" shaped bending plate 41d.

On the other hand, the upper plate 41b is formed with a second through hole 41e corresponding to the first through hole so that the adjustment bolt 30 passes. Through the second through hole (41e) to be fastened to the above-described adjustment bolt 30 and the transfer nut 42.

Then, the feed nut 42 is inserted into a portion adjacent to the upper plate 41b in the bending plate 41d and is fixed by the fixing protrusion 41f.

On the other hand, the two side plates 43 are arranged in the radial direction toward the circle center on the trunk flat cross section of the fixing cap.

Here, the maximum spacing between the side plates 41a is smaller than the spacing between the pair of guide rails 28 described above. Therefore, a portion of the block body portion 41 of the tightening block 40 is transported in the vertical direction while being sandwiched between the guide rails 28.

In the present embodiment, but the block body portion 41 is to illustrate the integral formation by welding each member described above, it is natural that the casting can be manufactured to increase the ease and rigidity in manufacturing.

The guide bracket 43 has a wedge shape in which the width of the radial direction is gradually narrowed toward the upper side in the height direction as opposed to the guide rail, and is fitted to the side plate 41a of the block body portion 41 on one side thereof. The catching protrusion 43a is formed to protrude.

In addition, the upper end of the guide bracket 43 forms an insertion hole 23 of the fixing cap 20 and is formed stepped to avoid interference with the bent end of the adjusting end 23 which is bent downward.

Therefore, the guide bracket 43 is coupled to both sides of the block body portion 41 to guide the tightening block 40 to move up and down along the inclined surface of the guide rail 28 by the operation of the adjustment bolt 30.

Here, it is preferable that the inclined surface of the guide rail 28 and the inclined surface of the guide bracket 43 which are in surface contact with each other when the tightening block 40 moves up and down are formed to have unevennesses corresponding to each other.

On the other hand, in this embodiment, the inclined surface of the guide rail 28 is formed to protrude in the cross-sectional shape of the equilateral triangle, and the inclined surface of the guide bracket 43 corresponding to this example is formed to be grooved in the cross-sectional shape of the equilateral triangle. However, the present invention is not necessarily limited thereto, and it can be obvious that the present invention can be formed with irregularities in various cross-sectional shapes.

As such, the inclined surface of the guide rail 28 and the inclined surface of the corresponding guide bracket 43 have a cross-sectional shape corresponding to each other to form an unevenness, so that the play in the left and right circumferential directions during vertical movement of the tightening block 40 is increased. To reduce it.

Hereinafter, the assembling and operating state of the pillar fixing device of the present embodiment will be described with reference to FIGS. 6 and 7.

In the assembling process of the pillar fixing device 1 of the present embodiment, first, the guide brackets 43 are fastened to the side plate 41a of both side plates 41a of the block body part 41 to which the feed nut 42 is fitted and fastened to the tightening block ( 40) Assemble.

Then, the adjusting bolt 30 inserted through the first through hole 26 of the fixing cap 20 and the second through hole 41e of the tightening block 40 is connected to the transfer nut 42 of the tightening block 40. By fastening, the respective fastening blocks 40 are coupled to the upper and lower transfers along the guide rail 20 of the fixing cap 20.

Finally, the fixing cap 20 to which the tightening blocks 40 are fastened is mounted on a concrete base or the like to be mounted on the fixed base plate 10 to penetrate the first fastening hole 15 and the second fastening hole 12. The fastening nut 52 is fastened to the fastening bolt 51 and fixed.
