DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a reinforcing steel mat holding jig used in a solidification process of foamed concrete, and then reassembling the reinforcing steel mat holding jig so as to correspond to a reinforcing steel mat to be newly held. The present invention relates to an apparatus for separating a jig frame of a reinforcing bar mat holding jig and a clamp with holes in an automatic reinforcing bar mat assembling system which automatically performs a series of steps for mounting a mat.

[0002]

2. Description of the Related Art Conventionally, in the production process of foamed concrete (ALC) used as a lightweight building material, when a foamed concrete is poured into a mold and solidified, a reinforcing steel mat for reinforcing the foamed concrete is used. It is set in the frame.

Until the foamed concrete is solidified to some extent, it is necessary to hold the reinforced mat so that it does not settle down or tilt under its own weight in the formwork. Then, fix both ends of the rod-shaped clamp with holes, insert a reinforcing bar pin into a pin support hole formed in the clamp with holes, assemble a reinforcing bar mat holding jig, and engage the reinforcing bar mat with a lower end of the reinforcing bar pin. The jig frame is positioned and fixed on the formwork in a state where it is suspended so that the reinforcing bar mat is held at a fixed position in the formwork.

After the foamed concrete is poured into the mold, before the foamed concrete is completely solidified, the reinforced pins are removed from the reinforced mat in the foamed concrete, and the reinforced mat holding jig is separated. The clamp with holes and the reinforced pins were separated from the jig frame, and the work of assembling the reinforced mat holding jig was again performed according to the size of the new reinforced mat.

[0005]

Conventionally, the steps of assembling the reinforcing bar mat holding jig and assembling the reinforcing bar mat as described above and disassembling the reinforcing bar mat holding jig after use have been performed almost manually. Therefore, the work efficiency is poor, and there is also a problem in the work environment such as work safety.

In particular, since the rebar mat holding jig must be accurately positioned with respect to the formwork, the jig frame and the hole clamp of the rebar mat holding jig are firmly fixed by fixing screw members. Separating the plurality of perforated clamps from the jig frame is extremely complicated and significantly reduces work efficiency.

Therefore, the present invention disassembles the reinforcing mat holding jig used in the solidification process of foamed concrete,
From the jig frame of the rebar mat holding jig, to automate the series of steps of assembling the rebar mat with the rebar mat holding jig re-assembled to fit the new rebar mat size and improve work efficiency It is an object to provide a device for separating a perforated clamp.

[0008]

In order to achieve the above object, the jig frame is stretched over a long frame of the jig frame on a movable frame movable along the long side of the jig frame above the rectangular frame-shaped jig frame. A socket assembly for moving back and forth to the fixing screw members of the plurality of clamps with holes to release the tightening of the fixing screw members, and lifting and lowering the clamps with the holes released and separating from the jig frame A free hand and a storage unit for receiving the separated hole clamps from the hand and temporarily storing the hole clamps until all the hole clamps on one jig frame are separated are provided. The above problem was solved by a clamp separation device with holes.

The storage portion is moved by the relay rail for receiving the separated clamp with a hole from the hand, a pushing dog for moving a clamp with a hole placed on the relay rail, and the pushing dog. It is preferable that a plurality of clamps with holes are constituted by a conveying roller for discharging the clamp to the side of the jig frame. In addition, it is desirable that the clamp separation device with holes is moved at every pitch of the clamp with holes on the jig frame.

[0010]

The hole-separated clamp separating device first grips the hole-mounted clamp spanned over the long side of the jig frame. Then, the socket assembly moves toward the fixing screw member to release the tightening, and the fixing of the jig frame and the clamp with the hole is released. The hand grips the clamp with the hole that has been released, and separates the clamp with the hole from the jig frame in this state. The perforated clamp separating device further has a storage section, and mounts the perforated clamp held by the hand on the storage section. After the separation of the plurality of perforated clamps fixed to the jig frame is completed, the reservoir discharges the perforated clamps to the side of the perforated clamp separating device.

The storage section is for collecting the same kind of perforated clamps fixed to one jig frame and then discharging the same from the perforated clamp separating device. The perforated clamp received from the hand is a relay rail. The push dog is activated temporarily, and is then moved one by one onto the transport roller. If this operation is repeated until all of the perforated clamps fixed to the jig frame are separated, the same type of perforated clamp is stored on the transport roller. Thereafter, the transport roller is activated and the group of perforated clamps is ejected laterally from the perforated clamp separating device.

Further, clamps with holes are fixed to the jig frame at a predetermined pitch according to the type of the reinforcing bar mat, and the clamp separation device with holes is moved at each pitch. After moving by a predetermined pitch, the hand, the socket assembly, and the storage section are operated, the perforated clamps on the jig frame are sequentially separated, and all the perforated clamps are placed on the storage section. For this reason, a rack extending in parallel with the long side of the jig frame is provided on the side of the perforated clamp separating device, and a traveling drive device is provided in the perforated clamp separating device. The traveling drive device has a drive pinion that meshes with the rack, and the drive pinions rotate according to the pitch of the hole clamps, whereby the hole clamps are sequentially separated. The above operation is performed by a control device to which processing procedure data is input in advance.

The reinforcing pin P penetrates the long hole M4 of the upper plate M2 and the long hole M5 of the lower plate M3, and the engaging portion P2 is engaged with the long hole M5 of the lower plate M3. The engaging portion P2 is shaped to be in an engaged state when the reinforcing pin P is rotated by a predetermined angle after being inserted into the elongated hole M5 of the lower plate M3. The engaging portion P2 has, for example, a shape having an oval cross section adapted to the long hole M5, and a groove is formed on both sides of the long diameter portion, and the engaging portion P2 is turned 90 degrees in the long hole 5M to form the groove. It can be shaped to engage with the short diameter portion of the long hole M5.
