正確に出す必要がある。[Problems to be solved by the conventional technology and invention Pitching of single-floor concrete is a method of finishing a continuous floor by installing stop frames at several divided splicing points and sequentially pouring concrete. However, in order to finish a continuous floor surface with even joints, it is necessary to accurately measure the height of the ends of the joints.

との付着力が弱く継ぎ目が良好に仕上がらないという不
都合が生じていた。However, in the past, a panel made of plywood or the like was used as a stop frame, and this panel stop frame did not allow for delicate height adjustments, making it difficult to obtain an accurate floor height. In addition, when concrete is spliced using this panel stopper frame, not only the corners of the concrete after splicing do not come out accurately, but also the rising surface of the concrete splice is smoothed by the relatively flat panel surface, which makes it difficult for the next step. The adhesion to the concrete poured in the concrete was weak, resulting in problems such as poor finishing of the joints.

ことを目的とする。The present invention has been developed in view of the above circumstances, and it is possible to easily and precisely finish the ends of poured concrete, to accurately bring out the corners of poured concrete, and to improve the rising surface of poured concrete. The purpose of the present invention is to provide a concrete floor pouring stopper frame and pouring method that can effectively exert concrete adhesion.

It is screwed into a predetermined location in the longitudinal direction of the square pipe in a penetrating manner, and is also screwed into a pedestal at the other end of the double screw bolt, the pedestal having a hole for fixing it to another member, A pouring stopper frame for a concrete floor, characterized in that the relative distance between the pedestal and the square pipe can be expanded or contracted by engaging a spanner or the like with a flat protrusion and rotating it, or The flat protruding side of a double threaded bolt formed with a screw and one end of which is formed to protrude flatly is screwed into a predetermined location in the longitudinal direction of the square pipe in a penetrating manner, and the other end side of the double threaded bolt After fixing the pedestal of the screw-in frame along the concrete joint position of the floor where concrete is to be poured, the rotation is adjusted by engaging a spanner or the like with the flat protrusion of both screw bolts. By doing this, the upper end surface of the square pipe is adjusted to the height of the floor where concrete is to be poured, and then, after hanging a rod member along the side surface of the square pipe, concrete is poured to match the upper end surface of the square pipe. After the poured concrete has hardened, both threaded bolts are rotated by the flat protrusion, and both threaded bolts are removed from the pedestal, and the square pipe is removed together with the both threaded bolts, leaving the pedestal as it is. Alternatively, the problem can be solved by a concrete floor pouring method characterized in that pouring concrete is poured by removing the pedestal as well.

とができる。1 Effect] The double threaded port used in the above-mentioned splicing stopper frame is formed by forming opposite threads on both sides of the threaded rod, and forming one end of the threaded rod to protrude flatly. The side to be screwed into the square pipe has a left-hand thread, and the side to be screwed into the square pipe has a right-hand thread.Thread each into the pedestal and the square pipe, and then install the pedestal on a base made of steel, concrete, or wood. While fixing by using screws using the holes in the pedestal or welding the pedestal itself, a spanner or the like is engaged with the flat protrusion at the upper end of both screw bolts that penetrate upward from the upper end surface of the square pipe. By rotating and adjusting the relative distance between the pedestal and the square pipe,
By using the upper end surface of this square pipe as a height reference surface for poured concrete, highly accurate concrete pouring height can be obtained.

As a result of screwing the pipe 2 upward, the relative distance between the square pipe 2 and the pedestal 3 increases, and the opposite action reduces the relative distance between the square pipe 2 and the pedestal 3, so the pedestal 3 is placed on the base 7. By fixing it, the upper end surface 2c of the square pipe 2 can be moved up and down with respect to the base 7. Therefore, by fixing this stopper frame 10 at the joint position of the floor concrete, the upper end surface 2c of the square pipe 2 can be easily and freely adjusted and used as a reference plane for the pouring height H of the floor concrete. can.

Concrete 12b should be poured using the upper end surface 2C of the upper square pipe 2 as the reference surface for the pouring height (Fig. 3fc))
, After the poured concrete has hardened, the left threaded part i is removed from the pedestal 3 by rotating both threaded bolts l to the right.
b, and attach both threaded bolts 11 to the base 7 together with the square pipe.
The pedestal is taken out from above, and while the pedestal remains fixed to the base 7, concrete 12c is poured into the gap left between concrete 12a and 12b to create a continuous concrete floor surface (Fig. 3(d)).

法。(2) The flat protruding side of the double screw bolt is formed by forming reverse threads on both ends and protruding flatly at one end, and screws the flat protruding side of the bolt into a predetermined position in the longitudinal direction of the square pipe in a penetrating manner, and After fixing the pedestal of the stop frame, which is formed by screwing the other end of the threaded bolt, along the concrete pouring position of the floor where concrete is to be poured, engage a spanner or the like with the flat protrusion of both the threaded bolts. Adjust the upper end surface of the square pipe to the height of the floor where concrete is to be poured by adjusting the rotation.
Next, after hanging a frame member along the side surface of the square pipe, concrete is poured to match the upper end surface of the square pipe, and after the poured concrete has hardened, both the threaded bolts are fixed by the flat protrusion. The method is characterized in that pouring concrete is poured by rotating to detach both threaded bolts from the pedestal, and removing the square pipe together with both the threaded bolts while leaving the pedestal as it is, or by removing the pedestal as well. Concrete floor pouring method.
