Description

[Detailed description of the invention] This invention relates to a reinforcing bar integrated setting jig for hoisting a large number of reinforcing bars, such as autoclave-cured lightweight aerated concrete (ALC), to a predetermined position. The present invention relates to a setting jig comprised of a setting frame and a setting rod, which is useful for automating the process of engaging strips with a setting rod to form an integrated set.

Conventionally, as shown in FIG. 1, the process of engaging and integrating a large number of reinforcing bars with setting rods involves using a setting frame 3 having a number of holes through which setting rods 1 can be suspended at predetermined positions. Place the setting rod 1 into the setting frame 3.
At the same time, the set rod 1 was inserted into the spacer 5 of the reinforcing bar 4, and then the set bar 1 was rotated 90 degrees to engage the set bar 1 and the reinforcing bar 4. 10-20 per set frame
Since there is a book setting stick, workers had to do it manually one by one, so there is a need to automate it, but if you consider automating the conventional method, the process and equipment will be complicated and expensive equipment will be required. becomes.

The present inventors attempted to automate the process of engaging a large number of reinforcing bars with a set rod to form an integrated set using simple equipment, and as a result of intensive research, they completed the present invention.

As shown in FIGS. 2, 3, and 4, the present invention has a connecting fitting 9 at the upper end, the main body 15 is a round bar, and the central upper part 7 and lower end part 8 are As shown in FIG. 2, a large number of chamfered setting rods 6 are held in a predetermined position, and the connection fittings 9 of the large number of setting rods 6 and the setting rod rotation lever 1 are movable in conjunction with a connecting plate. This is a reinforcing bar integrated setting jig having a setting frame 11 which is longer than the width of a large number of reinforcing bars to be set.

Incidentally, an example of the setting rod used in the setting jig of the present invention is shown in FIGS. 3 to 10. As seen in these figures, the chamfered part is preferably double-chamfered, and the lower part is preferably hook-shaped. In addition, the upper part 10 is
It is convenient to set the setting rod in the setting frame 11 by making it thicker than 5 and stopping at the lower frame of the setting frame 11. After setting the set rod 6 in this way, connect the connecting fitting 9 at the top of the set rod 6 to the pin 1.
4 to engage with the connecting plate 12. By rotating the setting rod rotating lever 13 provided at one end of the connecting plate 12 through 90 degrees, a large number of setting rods 6 connected by the connecting plate 12 can be simultaneously rotated through 90 degrees.

In addition, the reinforcing bars used when using the setting jig of the present invention to automate the process of engaging a large number of reinforcing bars with setting rods to form an integrated set are as follows:
As shown in FIG. 11, there are notches in the same direction above and below the reinforcing bars 16, connected to the notches,
This is a reinforcing bar in which a spacer 17 having a rotatable hole is fixed to the center of the set rod 6.

The chamfered portion of the upper central portion 7 of the setting rod 6 is made to correspond to the height of the upper spacer of the reinforcing bar 16, and the narrow portion of the chamfered portion of the lower end 8 of the setting rod 6 is made to correspond to the height of the lower spacer.

Next, we will show the process of using the setting jig of the present invention to engage a large number of reinforcing bars with setting rods to form an integrated set.

The reinforcing bar 16 in FIG. 11 is connected to the guide spacer 1 as shown in FIGS.
A large number of setting tools 7 are prepared on the trolley 18 at predetermined intervals, and a setting jig consisting of the setting rod 6 and the setting frame 11 of the present invention is provided above it.

Next, the setting jig is lowered to the position shown in FIGS. 14 and 15. The positional relationship between the setting rod 6 and the spacer 17 at this time is shown in FIG.

Here, the setting jig is moved in the direction of arrow E in FIG. 16, that is, in the lateral direction, and the setting rod 6 and the spacer 17 are fitted together as shown in FIG. 17. Thereafter, the setting rod 6 and the rotating lever 13 are rotated to engage the setting rod 6 and the spacer 17 as shown in FIG.

In this way, the setting jig of the present invention allows the process of engaging the reinforcing bar spacers and setting rods to be performed simultaneously with multiple reinforcing bars at regular intervals with high precision, and the fitting process of reinforcing bar spacers and setting bars to Since it can be carried out from the lateral direction, it is possible to automate the integrated setting process of reinforcing bars, and a large number of setting bars can be transported and moved together with a setting frame, and the concrete products can be pulled out of the setting bars. For example, the pulling process when the setting rod is hardened can be performed by rotating the setting rod rotating lever 1 90 degrees in the original direction, rotating the setting rod 90 degrees in the original direction, and then lifting the setting jig upward. Since it can be implemented,
There is no need to remove the set rods one by one from the reinforcing bars as in the past.
