BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a metal fitting for fixing the position of a pillar main bar.

[0002]

[Purpose of the invention] At the joint between the column and the beam, the main bars of the column and the beam converge and intersect. Therefore, it is essential that the position of the main bar of the initially formed column be accurate at first. It is necessary to fix the column main reinforcement accurately at a predetermined position when placing the column in concrete.

Conventionally, various metal fittings have been developed which are useful for fixing the position of the above-mentioned column main reinforcing bars. For example, fixed metal fittings such as the column main reinforcing bar space disclosed in Japanese Utility Model Application No. 2-40525 have been disclosed. It is inconvenient because it is necessary to remove the pillar main bar when it is likely to be caught in the mold.

SUMMARY OF THE INVENTION An object of the present invention is to prevent the pillar main bar from being easily caught by simply rotating the rotary plate having the column main bar position fixing groove upward without removing it at the time of removal from the mold. Another object of the present invention is to provide a pillar main bar position fixing metal which can hold a rotating plate in a horizontal operating position and a retracted position for upward rotation without providing a special stopper.

The structural features of the metal fitting for fixing the position of the main bar of the present invention include an angle member and a rotating plate attached to the inner surface of one side of the angle member via a hinge. A plurality of grooves for fixing the position of the pillar main bar are provided on the other end of the rotating plate body, which is fixed at a position slightly inside from the tip of the inner surface of one side, and one end of which is fixed to the other side of the hinge. It is in the point.

[0006] The pillar main bar position fixing bracket of the present invention has a column shape in which one side of the angle material to which the rotating plate is attached is horizontal, the inner surface thereof faces upward, and the tip faces the concrete casting side. It is used by being placed and fixed on the upper end surface of the frame, and at the time of placing concrete, the rotating plate with the groove for fixing the column main bar position is set to the horizontal operating position and the position of the column main bar is fixed, At the time of removal from the mold, the pivoting plate is pivoted to the upper retreat position to prevent the main pillar from being caught.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The embodiment shown in the drawings is applied to a square column-shaped formwork assembled by connecting two plane-shaped chevron-shaped divided unit form bodies at two points A and B. is there.

Reference numeral 1 denotes a frame which is attached to the upper end of the divided unit frame by bolts, and the illustrated frame 1 is formed by two angle members 2 and 3 into a planar mountain shape.

Each of the angle members 2 and 3 has one side horizontal and the other side vertical, and the tip of the horizontal side placed on the upper end surface of the divided unit frame faces the concrete casting side, and The tip is directed upward, and a rotating plate 4 is attached via a hinge 5 to a middle portion in the length direction of the horizontal side.

[0010] One side (fixed side) of the hinge 5 is fixed at a position slightly inside from the tip of the inner surface of the horizontal side of the angle member 2 (or the angle member 3), and the other side (rotation side) of the hinge 5 is horizontal. The pivot plate 4 can be pivoted upward from the position but cannot be pivoted downward. One end of the pivot plate 4 is fixed to the other side (the pivot side) of the hinge 5.

A plurality of grooves 6 for fixing the position of the main pillars are provided at appropriate intervals on the free edge of the rotating plate 4, and the rotating plate 4 is set to a horizontal position shown by a solid line in FIG. By engaging the column main bar 7, the position of the column main bar 7 is fixed.

The column form shown in the drawing is lifted upward while applying a force in the direction of pulling each divided unit form to the upper end (in this case, the direction in which each divided unit form is separated). Is not in the direction perpendicular to the angle members 2 and 3, the column main bar 7 is likely to be caught.) At the time of removal from the mold, the rotating plate 4 is rotated to the retracted position shown by a two-dot chain line in FIG. 7 is prevented from being caught.

[0013]

[Effect of the Invention] Since the metal fitting for fixing the position of the main column of the present invention is as described above, the following effects can be expected. That is, when necessary, the pivot plate is set to the horizontal operating position, and the column main bar is engaged with the column main bar position fixing groove provided on its free edge, whereby the position of the column main bar can be reliably fixed. it can. At the time of removal from the mold, the pivot plate is pivoted to the upper retracted position, so that the main pillar can be easily prevented from being caught, and it is not necessary to remove the metal fitting. It has a simple structure in which a rotating plate is attached to an angle member via a hinge, and is easy to manufacture as well as easy to handle. A rotating plate attached to the other side (rotating side) of the hinge by fixing one side (fixed side) of the hinge to a position slightly inside the tip of the inner surface of one side (horizontal side) of the angle material. Can be securely held in the horizontal position (operating position) without a special stopper, and the vertical side of the angle material also serves as a stopper when the rotating plate is turned to the upper retracted position. There is an advantage that the rotating plate is naturally held stably.
