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 bars are called reticulated double bars on a PC board and can be placed above and below. The 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 leave it at the intermediate position with a burl, chain block, etc. I was positioning.

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

Means for Solving the Problems In the present plan, in consideration of such a point, a work tool for temporarily holding the reinforcing rebar to be put inside the PC board when manufacturing the PC board (precast concrete board) is performed. 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. This working tool is provided with a U-shaped portion 1a that sandwiches the peripheral portion 2 of the PC plate frame, and a horizontal arm portion on which at least one reinforcing bar is placed.

Operation By using the work tools according to the present invention in several places, it is possible to easily perform the positioning work with the reinforcing bar fixing hardware while the reinforcing bar is floating in the middle position in the PC board manufacturing frame. At the same time, there was little contact between the tiles placed on the bottom surface of the formwork and the reinforcing bars, and the tile damage was greatly reduced.

Example FIG. 1 is a side view showing a relationship between a PC plate rebar temporary holding tool 1 and a PC plate reinforcing bar 3 according to the present invention, and FIG. 2 is a front view of the same as seen from an arrow AA in FIG. Is.

In the figure, reference numeral 1 is a tool for temporarily holding a PC plate reinforcing bar according to the present invention, which is a first horizontal arm for placing a U-shaped portion 1a that sandwiches a peripheral portion 2 of a PC plate frame on one end and one horizontal bar 3a on the other end And a section 1b. Alternatively, the second horizontal arm portion 1 on which other transverse lines can be placed
c may be provided. 2 is the peripheral part of the form, 3 and 3a are reinforcing bars for PC plate reinforcement, and the horizontal bars 3a have two upper and lower steps, and the first, second, ... horizontal bars in the upper row and a plurality of parallel horizontal bars with a space in the lower row. It is getting better. In addition, 4 is a tile, the upper side is the lower surface,
It is placed on the bottom 5 of the mold. Thus, P for the reinforcing steel bar 3
When mounting work at an intermediate position in the C plate form, a horizontal arm provided at the other end of the tool 1 by sandwiching the U-shaped part 1a provided at one end of the tool 1 using the form peripheral part 2 The lower end of the horizontal streak 3a is placed on 1b or 1c.

This tool 1 allows the reinforcing bars to be easily floated to an intermediate position in the PC board manufacturing form by supporting the periphery of the reinforcing bars with a plurality of tools, and in this floating state, positioning work by the reinforcing bar fixing hardware. Is possible. The tool according to the present invention has a size of about 150 to 800 mm. Effect of the invention As described above, in the present invention, by using the tool for temporarily holding the PC plate rebar, it is possible to avoid damage without touching a weak tile with a heavy rebar, Further, any one of the reinforcing bars can be sandwiched and supported by the U-shaped portion of the tool and supported by the mold to support the position, and can be fixed to the embedded metal article through the intermediate work.

[Brief description of drawings]

FIG. 1 is a side view showing a relationship with a reinforcing reinforcing bar 3 when the PC plate reinforcing bar holding tool 1 according to the present invention is used, and FIG. 2 is a front view seen from an arrow AA in FIG. In the figure, 1 is a tool for temporarily holding a PC plate reinforcing bar, 1a is a U-shaped portion of the tool, 1b and 1c are horizontal arms, 2 is a tile of a PC plate mold peripheral portion, and 5 is a bottom surface of the mold.
