SOLUTION: This device comprises the concrete form 1 having a cutout part 3 in the bottom of a frame body 2 and a screw hole 4 in the bottom of the frame body 2 corresponding to the part of the cutout part 3; and an adjusting member 7 having a rotatable bolt 6 to be screwed to the screw hole 4 on a base board 5 fixed to earth floor concrete by nailing or the like. The adjusting member 7 comprises a polygonal projection 8 at the upper end and a polygonal recessed part 9 in the bottom.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a concrete temporary frame level adjusting device for adjusting the horizontal state of a concrete temporary frame.

[0002]

2. Description of the Related Art A temporary frame used for a concrete building or the like is required to maintain a horizontal state at a construction site. Conventionally, as a means for this, a cutting edge of a plywood is inserted into the bottom of the temporary frame. I have.

[0003]

According to the above-mentioned conventional method, not only is the work extremely troublesome, but it is difficult to obtain an accurate horizontal state, and the work efficiency is significantly reduced. is there. SUMMARY OF THE INVENTION It is an object of the present invention to provide a concrete temporary frame leveling device in which a plurality of bolts are mounted on the bottom of a temporary frame, and the horizontal adjustment can be easily performed by rotating the bolts.

[0004]

According to the present invention, as a means for achieving the above object, a notch 3 is provided at the bottom of a frame 2;
A temporary concrete frame 1 having a screw hole 4 at the bottom of the frame 2 in the notch 3 portion, and a rotation screwed into the screw hole 4 on a base plate 5 fixed on the interstitial concrete by nailing or the like. An adjusting member 7 having a possible bolt 6.
A polygonal projection 8 was provided at the upper end of the adjusting member 7 and a polygonal concave portion 9 was provided at the bottom.

[0005]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The concrete structure of the present invention will be described with reference to the drawings. The temporary frame may be made of synthetic resin, wooden, or the like. A screw hole 4 is formed in the notch 3. When the temporary frame 1 is made of synthetic resin, the screw hole 4 can be directly formed. However, in the case of a wooden temporary frame, a nut is embedded in the bottom of the frame 2.

[0006] Next, a wooden plate 5a is adhered to a part of the base board 5 and a hole 5b for nailing is formed in the adjustment member, and a bolt is formed in a perforated portion of the raised portion 5c on one side. 6 can be rotatably mounted, and this mounting means can be erected such that the inner peripheral end of the perforated portion is engaged with an annular groove 10 formed in the lower outer peripheral surface of the bolt 6. Then, a polygonal projection 8 is formed at the upper end of the bolt 6 and a polygonal recess 9 is formed at the bottom.

A plurality of screw holes 4 are formed in the frame 2 of the temporary frame 1, and the bolts 6 of the adjusting member 7 are screwed into the screw holes 4. When screwing the bolt 6 into the screw hole 4,
The bolt 6 is inserted from the bottom of the screw hole 4, and the bolt 6 is rotated by an appropriate tool using a polygonal concave portion 9 provided at the bottom of the bolt 6, and screwed into the screw hole 4.

Then, a temporary concrete frame is erected on the slab concrete to form a blind hole 5b of the base plate 5 of the adjusting member 7.
The base plate 5 is fixed by nailing, and when the concrete temporary frame is inclined to one side, the temporary frame is pushed up by rotating the bolt 6 of the adjusting member 7 on the inclined side, and the horizontal adjustment is performed. Fine adjustment can be performed easily, quickly and accurately. When the bolt 6 is rotated, a tool is engaged with the polygonal projection 8 protruding from the upper end of the bolt 6 to rotate.

[0009]

According to the present invention, the concrete temporary frame is moved up and down by the rotation of the bolt 6, so that the horizontal adjustment of the temporary frame can be performed easily and quickly, and the working efficiency can be remarkably improved. , By screw adjustment, which has the advantage that fine horizontal adjustment is possible and an accurate horizontal state can be ensured.
