Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a reinforcement V4 arrangement in the formation of regular reinforcing bars used for concrete piles, concrete tubular products, etc.

<Prior Art> Regular reinforcing bars used for concrete piles, concrete tubular products, etc. are composed of a plurality of longitudinal bars and spiral bars. To manufacture such cage-type reinforcing bars, multiple vertical bars are arranged in a cylindrical shape, the ends of which are supported by a reinforcing device, and the vertical bars supported by this reinforcing device are moved while spiral bars are placed on the outside. Wrap it around and weld the intersection of the vertical reinforcement and spiral reinforcement to form release reinforcement.

In the conventional knitting machine for releasing reinforcing bars as described above, the diameter and number of longitudinal reinforcing bars to be arranged differ depending on the size of the concrete pile or concrete pipe to be manufactured. Therefore, in the past, vertical reinforcing bars of various sizes are prepared and replaced every time the diameter of the release reinforcing bars to be knitted changes.

<Problems to be Solved by the Invention> In the conventional apparatus as described above, it is necessary to replace the longitudinal reinforcing bars every time the size of the release reinforcing bars to be manufactured changes, so the replacement work is extremely time-consuming. This is time consuming and inefficient.

In addition, recently there has been a large demand for large-sized release reinforcing bars, and in the case of such large-sized release reinforcing bars, the diameter of the vertical reinforcement becomes large, and the weight thereof becomes significantly large.

Therefore, the reinforcing bars that support it are also large, and the reinforcement plates are naturally also large. Therefore, the conventional method of replacing the reinforcing bars every time the size of the release reinforcing bars to be manufactured changes, it is not necessary to replace them. A problem arose that it became impossible to do it manually.

In the case of such large-scale reinforcement plates, even if the number of vertical reinforcements and the reinforcement spacing change due to changes in the size of the release reinforcing bars to be organized, the reinforcement plates can be left as they are and do not need to be replaced. A muscle device is provided.

<Means for Solving the Problems> This invention was made to solve the above problems, and includes providing a plurality of vertical reinforcement insertion holes into which one ends of the plurality of vertical reinforcements of the release reinforcing bars are inserted. The reinforcing plate and the reinforcing plate can be attached and detached at will.
The vertical reinforcement insertion holes are elongated in the inner and outer directions so as to accommodate release reinforcing bars of different diameters, and the brackets are provided with predetermined vertical reinforcements of the reinforcement plate. It is equipped with a cam that presses the end of the vertical reinforcement inserted into the insertion hole to the supporting part of the bracket, and a drive means for this cam. For example, the plurality of vertical reinforcement insertion holes provided in the reinforcement plate are One is a straight long hole in the radial direction arranged on the circumference with the same name as the center of the plate, and the other is a long hole bent in a dogleg shape, with different lengths, and the outer end of each insertion hole is It is arranged on the circumference with the same name as the center of the reinforcement plate, so that the number of insertion holes on the inner circumference is smaller than the number of insertion holes on the outer circumference,
Further, for example, the driving means for the cam uses a cylinder operated by hydraulic pressure or air.
