Description

TECHNICAL FIELD The present invention relates to a guide device for a set rod in a reinforced reinforcing cage block assembly used in an ALC manufacturing process.

(Prior Art) Conventionally, when inserting the set rod into the spacer of the reinforcing braces, a separate guide device has not been provided. Then, as a countermeasure against the misalignment of the set rod, only a means of making the tip of the set rod into an acute angle has been adopted.

(Problems to be Solved by the Invention) However, in assembling the reinforcing bar cage block in which the setting bar is lowered and inserted into the spacer of the reinforcing bar cage to assemble the reinforcing bar cage block, the bending of the set bar and the error of the positioning device are caused. Due to the displacement of the spacer and the like, misalignment between the spacer hole of the reinforcing bar and the set bar is likely to occur. Therefore, if no measures are taken, the set bar may not fit into the spacer of the reinforcing cage, the reinforcing cage cannot be suspended, and the reinforcing cage block cannot be assembled properly.

Further, the means for making the tip of the set rod into an acute angle is not effective because the amount of misalignment that can be tolerated is small. Further, a means of disposing a funnel-shaped guide above the spacer is also conceivable, but it is not appropriate because the mechanism becomes complicated such that the funnel must be divided in order to retract the guide after inserting the set rod.

(Means for Solving the Problems) Therefore, in order to solve the above problems, when the set rod is lowered and inserted into the spacer of the reinforcing braces, the rotating shafts are arranged horizontally in parallel with a predetermined interval. Reinforcing bar characterized by having a bow tie type butterfly guide to be attached and elevating means for moving the butterfly guide to a predetermined height, and guiding the set rod mounted on the set frame to the spacer of the reinforcing bar cage. A guide device for the set rod in the basket block assembly was constructed.
