Description

DETAILED DESCRIPTION OF THE INVENTION "Industrial Utilization Frame" The present invention relates to ready-made cylindrical reinforcing bars and the insertion of their inner frames in the production of long small diameter concrete pipes (4 to 5+++).

``Conventional technology'' Conventionally, the outer frame was placed upright and reinforcing bars and inner frames were inserted into it, but this was difficult to apply to long and small diameter concrete pipes, so the outer frame was placed horizontally (laterally) and reinforcing bars were inserted into it. Then, the upper parallel rod of the metal fitting, which connects one end of the long parallel rod to the hollow part of the reinforcing bar, is suspended by a crane, the inner frame is supported by the upper parallel rod, and the upper parallel rod is moved along the top surface of the horizontal outer frame. , the upper parallel rod was inserted into the hollow part of the reinforcing bar together with the inner frame, and the inner frame got caught on the reinforcing bar, damaging the reinforcing bar.

"Problems to be Solved by the Invention" The present invention aims to quickly and easily insert an inner frame into the reinforcing bars without interfering with the horizontal reinforcing bars.

"Means for Solving the Problems" The present invention supports a plurality of inner frame support rollers above a white surface at the same level and in the same direction, and at least an inner frame support roller is supported above a white surface at the same level and in the same direction. It is characterized by an inner frame insertion device that is spaced apart by reinforcing bars extending in the longitudinal direction.

"Operation" The inner frame supported by the inner frame support roller is supported by the upper surface of the roller that projects above the reinforcing bars supported on the table surface within the above-mentioned interval, and is quickly inserted into the space of the reinforcing bars.

``Example'' ■ Two parallel beams 2.2 are provided on a plurality of beam support stands 1 so as to be able to approach and separate from each other (bolts are tightened along the elongated holes 3 in Fig. 5), and the upper surface thereof is the stand surface. 4, a roller supporting flaket 7 is welded onto the stand piece 6 which is movably engaged with the upper flange 5 of the parallel I beam 2, and the inner frame supporting roller 8 is pinned to the upper part 6 of the bracket 7. 9, and a plurality of these are provided at the same level. Although six are provided in FIG. 2, any spacing that allows horizontal movement of the inner frame 10 is sufficient. The upper surface level of these rollers 8 and the above-mentioned base surface 4
A reinforcing bar support jack 11 may be placed between the
It is also possible to directly support the reinforcing bars 12 on the table surface 4 (Fig. 7). The reinforcing bars 12 are horizontal reinforcing bars that extend in the longitudinal direction of the inner frame 10 as shown in Fig. 4, and are connected to the reinforcing bars 12, 12 and A roller 8 is inserted between the orthogonal reinforcing bars 13 and 13, and the upper surface level of the roller 8 is projected to a level below the reinforcing bars 13 and slightly above the reinforcing bars 12. In this state, as shown in FIGS. 2 and 4, the lower reinforcing bar 12 of the hollow reinforcing bar 14 is
1 with a crane and expose or protrude the upper surface level of the roller 8 on the lower reinforcing bar 12, and push the inner frame 10 placed on the roller 8 to the left as shown in Fig. 2. The frame 10 slides on the rollers 8 and is inserted into the hollow part of the reinforcing bar 14 as shown in FIG. A long small diameter concrete pipe can be formed by fixing the position of the reinforcing bars 14 and pouring concrete between the inner and outer frames.

"Effects of the Invention" Since the present invention is configured as described above, the inner frame can be quickly and easily inserted into the hollow reinforcing bars placed laterally without interfering with the reinforcing bars, and the inner frame can be inserted into the hollow reinforcing bars placed laterally without interfering with the reinforcing bars. The inner frame insertion process can be performed safely.
