It is a reinforced squirrel cage trolley that carries a large number.

(Problems to be Solved by the Invention) In order to automate the assembling of the reinforcing bar cage, it is necessary to load the reinforcing bar cage in an aligned manner on an alignment carriage having an alignment jig in advance.

At this time, it is effective to use an aligning jig to regulate the mutual positions of the reinforcing reinforced baskets and to mount them on the aligning table while holding them.

In Japanese Utility Model Publication No. 1-20094, the alignment guide is fixed to the alignment carriage and cannot be easily removed. For this reason, correspondence to different board thicknesses is limited to two types, and for other board thicknesses, another bogie must be prepared.

Further, when assembling a large number of flexible reinforced baskets for one formwork, it is necessary to assemble the vertical position and the front-rear position accurately, which is inefficient because it is done manually by the conventional technique.

Therefore, it is an object of the present invention to provide a reinforcing-bar cage alignment jig for accurately positioning according to the type of the reinforcing-bar cage and a reinforcing-bar cage alignment table for placing the reinforcing bar cage at a predetermined position. Is.

(Means for Solving the Problems) In order to achieve the above object, the present invention provides the following reinforcing jig basket alignment jig and a reinforcing bracket basket alignment table for mounting the jig in a predetermined position. Is provided.

That is, it has a rod-shaped alignment guide for aligning a plurality of reinforcing baskets at predetermined intervals in the plate thickness direction, plays a role of guiding the insertion of the lower spacers of the reinforcing baskets, and tapers each other at the upper end. The reinforcing jig basket alignment jig is characterized in that it has fixed guides whose slopes face each other between the alignment guides, and has engaging means for positioning and setting with respect to the alignment table at the bottom.

 The engaging means of the alignment jig is a rack.

Further, the alignment table on which the alignment jig as described above is mounted has the following configuration.

When it is necessary to manufacture ALC panels with different thicknesses, it is necessary to use reinforcing bar cages with different thicknesses, but even in such a case, simply changing the spacing between the alignment guides will change the reinforcing bar cages. It can be held at predetermined intervals.

In addition, since this jig has fixed guides on the upper end between the alignment guides, the slopes of which open in a tapered shape are opposed to each other, the jig serves to guide the insertion of the lower spacer of the reinforcing bar basket and also the reinforcing bar. The upper and lower positions of the basket can be fixed at a predetermined height,
Since the lower part has an engaging means such as a rack, the aligning jig can be fixed at a predetermined position on the aligning stand.

Further, since the aligning carriage has the engaging means such as a rack which engages with the engaging means such as the rack of the aligning jig on the upper portion of the frame provided with the wheels, the aligning jig can be positioned and fixed. .
