Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a tool for temporarily holding a PC plate rebar.

2. Description of the Related Art Reinforcing reinforcing bars are referred to as reticulated double reinforcing bars on a PC board and can be placed above and below. The reinforcing bars reach a length of 7 m and a width of 3 m and are large and heavy. When installing this reinforcing bar at an intermediate position in the PC plate form, temporarily place the reinforcing bar on the bottom of the form and fix it while floating it in the intermediate position with a crowbar, chain block, etc. I was positioning with hardware.

However, this method is inefficient in working and damages tiles etc. due to direct contact with temporarily placed reinforcing reinforcing bars when driving PC board surface decoration tiles etc. There were many

Means for Solving the Problems In the present proposal, in consideration of such a point, a work tool for temporarily holding the reinforcing reinforcing bar to be put inside the PC board when the PC board (precast concrete board) is manufactured This tool is provided, and this tool is used for temporary holding of the reinforcing bar, and by supporting the periphery of the reinforcing bar, the reinforcing bar is easily left floating in the middle position in the PC board manufacturing formwork. ,
Positioning work can be performed with a metal fixture fixed to the rebar. As this working tool, a U-shaped portion 1b for inserting one of the vertical stripes so as to sandwich it in the horizontal direction, a first horizontal portion 1a placed on the upper ends of the other vertical stripes, and the peripheral portion of the formwork. Two
And a second horizontal portion 1c placed on the upper surface of the.

The work tool according to the present invention has one vertical stripe 3a on the U-shaped portion 1b.
(Generally, the end vertical streaks) are clamped, and the other vertical streaks 3c (generally the adjacent vertical streaks) held by the first horizontal portion 1a are used as rotation stoppers and shown in FIG. Thus, the reinforcing bar incorporated in the second horizontal portion 1c can be supported at a predetermined position (height). In the illustrated embodiment, the first horizontal portion 1a is The second horizontal portion 1c is provided on each of the strips, and the strips are integrally formed by welding, and a U-shaped portion 1b is formed at an intermediate position including the welded portion.

Function By using multiple work tools according to the present invention in several places, it is possible to easily position the reinforcing bars with the reinforcing bar fixing hardware while floating in the middle position in the PC board manufacturing form. Along with the improvement, there was little contact between the tiles placed on the bottom of the formwork and the reinforcing bars, and the tile damage was greatly reduced.

Example FIG. 1 is a side view showing the relationship between the PC plate rebar temporary holding tool and the PC plate reinforcing bar 3 according to the present invention, and FIG. 2 is the same front view as seen from the arrow AA of FIG. is there. Further, FIG. 3 shows a tool 1 for temporarily holding a PC plate reinforcing bar and a reinforcing bar 3 for reinforcing a PC plate according to the present invention.
It is a perspective view which shows the relationship with a, 3b, and 3c. In the figure, reference numeral 1 is a tool for temporarily holding a PC plate reinforcing bar according to the present invention, and a first horizontal portion 1a at one end, and a U-shaped portion 1 integrally formed with the first horizontal portion 1a.
b and a second horizontal portion 1c at the other end. 2 is a peripheral portion of the form of the PC board, 3, 3a, 3b, 3c ...
The reinforcing bars for plate reinforcement have two vertical steps, and are composed of first, second, third, ... Vertical bars in parallel in the upper row and a plurality of vertical bars parallel to each other at intervals in the lower row.

In addition to this, the vertical lines have horizontal lines and are combined like a net. Further, 4 is a tile, which is placed on the bottom surface 5 of the formwork with the upper surface facing down. Thus, when the reinforcing rebar 3 is attached to the intermediate position in the PC plate form, the second horizontal part 1c of the tool 1 is placed on the peripheral part 2 of the form and the U-shaped part is used. 1b
With one vertical streak, for example the first vertical streak 3a,
The horizontal part 1a of the second vertical line 3b, which is another vertical line,
Place on top of 3c. By supporting a plurality of the reinforcing bars around this tool 1, the reinforcing bars can be easily floated to an intermediate position in the PC board manufacturing frame, and in this floating state, positioning is performed by the reinforcing bar fixing hardware. Work becomes possible.

The tool according to the present invention has a size of about 150 to 800 mm.

Effect of the Invention In this way, according to the present invention, by using the tool for temporarily holding the PC plate reinforcing bar, the heavy reinforcing bar can prevent damage without touching the weak tile, etc., and one of the reinforcing bars is a U-shaped part of the tool. It is possible to support it by holding it in place by holding it against the formwork, and to fix it with embedded hardware etc. during this intermediate work.
