SOLUTION: The processing line 2 of a reinforced mat automatic assembly system first removes reinforcing pins from a clamp with a hole of a reinforced mat holder and stores them in a pin storage line W1 in the first step. The line 2 removes the clamp from a jig frame, and stores it in a clamp storage line S1 in the second step. The line 2 removes the clamp and mounts it at the new designated position of the frame in the third step. Further, the line 2 inserts a reenforcing pin into the clamp, completes the assembling of the mat with the reinforcing mat holder, and again sends it to the step of solidifying foamed concrete of a main line 1 from a delivery line 4 in the fourth step. The line 2 then summarizes and controls the units by the controller to assemble corresponding to the size and type according to the input processing procedure data.

It is set in the frame.

It is necessary to hold the rebar mat so that it will not settle down or tilt down due to its own weight in the form until the foamed concrete is solidified to some extent. Conventionally, a frame-shaped jig frame is used. Fix both ends of the rod-shaped hole clamp to, and insert the reinforcing bar pin into the pin support hole formed in the hole clamp to assemble the reinforcing bar mat holding jig, and engage the reinforcing bar mat with the lower end of the reinforcing bar pin. The jig frame was positioned and fixed on the mold in a state of being suspended so that the reinforcing bar mat was held at a fixed position in the mold.

Then, after the foam concrete is poured into the mold, after the foam concrete is not completely solidified, the rebar pins are removed from the rebar mat in the foam concrete and the rebar mat holding jig is separated. The clamp with hole and the reinforcing bar pin were separated from the jig frame, and the reinforcing bar mat holding jig was assembled again according to the size of the new reinforcing bar mat.
