DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for adjusting and supporting the level of a concrete column member in a building using the concrete column member.

[0002]

2. Description of the Related Art Conventionally, when adjusting the level of an outer column concrete member in a building having an outer column concrete member, it is necessary to use a base concrete or a slab concrete and a lower end surface of the outer column concrete member disposed thereon. In between, a wedge for level adjustment is cast to adjust the level of the concrete member of the outer column.

[0003]

In order to adjust the level of the concrete member of the conventional outer column, the level adjusting wedge is used, so that the level adjusting accuracy is low and the level adjusting operation is complicated. Also, when concrete is poured into the outer column concrete member, if an earthquake force or other vibration acts, the outer column concrete member may be shifted.

[0004]

SUMMARY OF THE INVENTION In order to advantageously solve the above-mentioned problems, in the apparatus for adjusting the level of a concrete member of an outer column according to the present invention, a frame 2 formed by welding a metal wire 1 by welding is provided. At the lower part of each side of the rectangular outer pillar concrete member 3, a vertical female screw cylinder 4 is fixed, and a level adjusting bolt 5 is screwed into each female screw cylinder 4 from above to form a level adjusting support member 6. The level adjusting support 6 is placed on the upper surface of the foundation concrete or the slab concrete 7, and the finishing concrete 8 is cast near the upper end of the female screw cylinder 4, and the upper end of each of the level adjusting bolts 5. The outer column concrete member 3 is placed on the outer column concrete member 3 and the level of the outer column concrete member 3 is adjusted by the respective level adjusting bolts 5. A lower formwork 9 is provided between a lower outer surface and an upper surface of the finishing concrete 8, and a formwork fixing wedge is provided between a support rod 11 continuously provided around the frame 2 and each lower formwork 9. 13 is then cast, and then the column concrete 10 is cast inside the outer column concrete member 3 and the lower formwork 9.

3 to 6 show a level adjusting support 6 used in an embodiment of the present invention. A vertical support rod 11 is attached to both ends of a horizontal metal wire 1 made of a round steel bar. Are bent and connected upward, the middle portions of the four metal wires 1 are superimposed in a grid pattern, and the overlapped portions of the metal wires 1 are joined by welding to form a quadrangular frame 2. Are connected to the frame 2 by welding.

[0006] Concrete member 3 for outer pillar having a rectangular cross section
In the lower part of each side of the lower end surface of the above, a vertical female screw cylinder 4 is arranged, each female screw cylinder 4 is fixed to the metal wire 1 by welding, and a level adjusting bolt 5 is screwed from above into each female screw cylinder 4. The frame 2, the reinforcing metal wire 12, the female screw cylinders 4, and the level adjusting bolts 5 constitute a level adjusting support member 6.

FIGS. 1 and 2 show an apparatus for adjusting the level of a concrete member of an outer column according to an embodiment of the present invention using a level adjusting support 6 shown in FIGS. Alternatively, the level adjusting support 6 is placed at a predetermined position on the upper surface of the slab concrete 7, and the finishing concrete 8 is cast on the upper surface of the foundation concrete or the slab concrete 7 to near the upper end of the female screw cylinder 4. The upper surface of the finishing concrete 8 is leveled horizontally. The column main bar 14 is held at a predetermined position by the frame 2 and the outer column concrete member 3.

Next, after the curing of the finishing concrete 8 is completed, the lower end surface of the outer column concrete member 3 is placed on the upper surface of each level adjusting bolt 5, and the outer column concrete member 3 is set by each level adjusting bolt 5. Level 3 and verticality are adjusted. Next, outer column concrete member 3
Are arranged on the outer surface of the lower part, and the four lower forms 9 surrounding the lower form 9 are placed on the upper surface of the concrete 8 for finishing. A frame fixing wedge 13 is cast, and then the outer column concrete member 3
Column concrete 1 inside the inside of the lower formwork 9
0 is cast.

After curing the column concrete 10,
The formwork fixing wedge 13 and the lower formwork 9 are removed.

[0010]

According to the present invention, a vertical female screw cylinder 4 is fixed to a frame 2 formed by welding metal wires 1 by welding, at the lower part of each side of a rectangular outer column concrete member 3, A level adjusting bolt 5 is screwed into each female screw cylinder 4 from above to form a level adjusting support 6, and the level adjusting support 6 is placed on the upper surface of the foundation concrete or the slab concrete 7. The concrete 8 for finishing is poured into the vicinity of the upper end of the cylinder 4, and the outer column concrete member 3 is placed on the upper end of each of the level adjusting bolts 5. 3 and the lower formwork 9 is installed between the lower outer surface of the outer column concrete member 3 and the upper surface of the finishing concrete 8, and is continuously provided around the frame 2. Forming wedges 13 are fixed between the support rod 11 and each lower form 9 and then the column concrete 10 is formed inside the outer column concrete member 3 and the lower form 9. By rotating the level adjustment bolt 5, the level and verticality of the outer column concrete member 3 can be accurately adjusted, and the adjustment can be performed easily and quickly. Further, an upper portion of a lower formwork 9 that closes a gap between a lower end surface of the outer column concrete member 3 and an upper surface of the finishing concrete 8 is in contact with an outer surface of the outer column concrete member 3, and an outer surface of the lower formwork 9. Since the wedge 13 for form fixing is interposed between the support rod 11 and the support rod 11, when the column concrete 10 is driven into the outer column concrete member 3 and the lower part of the lower form 9, an earthquake or other vibration occurs. Accordingly, it is possible to prevent the outer column concrete member 3 from shifting and moving in the lateral direction, and it is possible to hold a large number of column main reinforcements 14 in a predetermined position using the frame 2 and the outer column concrete member 3. .
