Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a footwork fitting for a pillar formwork for vertically supporting the pillar formwork on the floor surface.

(Prior art and its problems) When a pillar formwork is erected on the floor surface, in order to adjust the level of the pillar formwork and to prevent the clearance between the pillar formwork and the floor surface, Although the tree is nailed to the outside and this tree is placed on the floor, it is difficult to adjust the level of the pillar formwork, and much labor and time are required.

(Means for Solving the Problems) In order to solve the above conventional problems, the present invention provides
A horizontal support plate that supports the lower end of the column form is projected outside the horizontally long vertical strip at a height lower than the upper end of the vertical strip, and the column form placed on the horizontal support plate is projected. The horizontal supporting plate is provided with a wedge driving portion that is clamped and fixed between the vertical supporting plate and the vertical supporting plate, and the height is adjusted below the horizontal supporting plate so that the vertical supporting plate stands on the floor. The present invention proposes a footwork for a pillar formwork, which is formed by disposing a plurality of possible supporting screws.

(Embodiment) An embodiment of the present invention will be described below with reference to the attached exemplary drawings.

FIG. 1 shows that four foot fittings 1 according to the present invention are arranged in a square shape on a floor surface, and four pillar formwork 2 are placed on the square shape in a square tube shape. 2 shows a state in which concrete is cast in a space surrounded by the column formwork 2 to construct a column 3 having a square cross section.

As shown in FIG. 2 to FIG. 4, each foot fitting 1 includes a horizontally long vertical strip 4 and a horizontal support plate 5, which is provided on the outside of the vertical strip 4 so as to project from two locations in the longitudinal direction. 6 and two wedges 7,8
And the supporting screws 9 and 10 attached to the front and rear two positions below the horizontal support plates 5 and 6, respectively. A reinforcing angle member 11 is fixed to the outside of the vertical strip 4 at an intermediate height position, and the inner end portions of the horizontal support plates 5 and 6 are placed and fixed on the angle member 11. The horizontal support plate 5,6
The vertical strip-shaped plate 4 is configured to project upward. Further, in the middle of the horizontal support plates 5 and 6, a wedge drive portion 14 including a wedge drive hole 12 and a wedge receiving angle member 13 fixed to the lower side of the horizontal support plates 5 and 6 is formed. Further, long nuts 15 and 16 are provided at two front and rear positions below the horizontal support plates 5 and 6.
Are vertically fixed, and the supporting screws 9 and 10 are screwed into the long nuts 15 and 16 so that the height can be adjusted upward.
The hexagonal head 9a of the inner supporting screw 9 directly abuts on the floor surface 17, while the outer hexagonal head 9a of the outer supporting screw 10 is in contact with the floor surface 17.
The ground plate 18 fixed to the lower side of the bottom abuts the floor surface 17. or,
The ground plate 18 is provided with a through hole 19 for driving concrete nails.

A notch 20 having an upper end at the same level as the upper surfaces of the horizontal support plates 5 and 6 is formed at one end in the lengthwise direction of the vertical strip plate 4 over an appropriate length.

The foot fitting 1 configured as described above is placed at a predetermined position on the floor surface 17 through a total of four supporting screws 9 and 10, and the supporting screws 9 and 10 are rotated to operate for a long time. By vertically moving the nuts 15 and 16 up and down, the vertical strip 4 is tilted up and down to be vertically erected, and both horizontal support plates 5 and 6 are vertically erected.
Adjust the level so that is horizontal at the same level.
Further, as shown in FIG. 3, the two foot fittings 1 which are adjacent to each other at a right angle have one end on the other foot fitting 1 on which the notch portion 20 of the vertical strip 4 is provided on one foot fitting 1 on the other foot fitting 1. The vertical strip 4 is arranged so as to come into contact with the inner surface of the end on the side having the cutout 20.

After the level adjustment of each foot fitting 1 is completed as described above, the lower end ground plate 18 of the outer supporting screw 10 in each foot fitting 1 is fixed on the floor surface 17 with concrete nails. When there is a gap between the lower end of the vertical strip 4 and the floor surface 17, the sloping stop 21 is placed on the floor surface 17 so as to abut on the outer surface of the lower end of the vertical strip 4. It may be fixed to the floor 17 or the vertical strip 4. Also, this Noki 21
Only when there is a gap between the floor 17 at the lower end of the vertical strip 4 and when the foot bracket 1 is placed on the floor 17 rather than rearwardly.
Before being placed and fixed on the floor 17, it is fixed at a predetermined position on the floor surface 17 with concrete nails, double-sided adhesive tape or the like, and the outer surface of the vertical strip 4 is brought into contact with the inner surface of the sloping stop 21. It is desirable to dispose the foot fitting 1 in such a manner.

After the four foot fittings 1 have been arranged at the predetermined positions on the floor surface 17 as described above, the lower end of each pillar formwork 2 is placed on the horizontal support plates 5, 6 of each foot fitting 1. Then, by driving the wedges 7 and 8 downward into the wedge driving holes 12 of the wedge driving portion 14, the lower end portion of the column frame 2 is clamped between the wedges 7 and 8 and the upper end portion of the vertical strip plate 4. Fix it. At this time, one of the two pillar forms 2 that are adjacent to each other at a right angle is provided with a notch of the vertical strip 4 in the foot fitting 1 that supports the other pillar form 2 as shown in FIGS. 3 and 4. The end face of the other column form can be abutted while covering the part 20. If the ground plate 18 is not fixed to the floor surface 17, the pillar formwork 2 is placed on each foot fitting 1 and then the supporting screws 9 and 10 of each foot fitting 1 are rotated, It is also possible to adjust the level of the pillar formwork 2.

The horizontal support plates 5 and 6 can be integrally formed by using one long plate. Also, the width of the pillar formwork 2 used is
If the width of the pillar 3 to be built is the same, the vertical strip 4
The notch 20 provided in the is not necessary. Furthermore, a strip-shaped plate corresponding to the sloping stop tree 21 may be attached to the vertical strip-shaped plate 4 so that the height and the angle thereof can be adjusted by the long holes and the fastening screws.

(Operation and Effect of the Invention) As described above, according to the footwork bracket for a pillar formwork of the present invention, it is placed at a predetermined position on the floor surface through a plurality of supporting screws to horizontally support the footwork fitting. The lower end of the column formwork is placed on the plate, and the lower end part of the column formwork is clamped and fixed between the wedge driven into the wedge driving part and the upper end part of the vertical strip plate. The level of the pillar formwork can be adjusted by using the supporting screws.

Therefore, not only can the level adjustment of the pillar formwork be performed easily and accurately, but even when a sloppy retaining tree must be used together, the level adjustment of the pillar formwork can be performed with this sloping retaining tree. Therefore, the anti-loosening effect can be obtained reliably and easily.
