Abstract: The present invention provides a rebar cage module comprising a first opening rebar net and a second opening rebar net. The first opening rebar net extends from a central direction, and partially forms an elongated groove shape enclosing a first accommodating portion, and has a first opening. The second opening rebar net extends from the central direction, and partially surrounds the central direction to form an elongated groove shape, and has a second opening oriented to the opposite direction with the first opening. Wherein, the first opening rebar net at least partially covers the second opening rebar net, the first opening rebar net is at least partially distributed in the second opening, and the first opening rebar net extends at least partially through the second opening into the second accommodating portion, and making the first accommodating portion and the second accommodating portion at least partially overlap.

Abstract: A stirrup module includes first, second, third and third erect bar portions, a bottom rib section. The second erect bar portion is arranged in parallel with the first erect bar portion. The third erect bar portion is arranged in parallel with the first erect bar portion and located between the first and second erect bar portions. The fourth erect bar portion is arranged in parallel with the first erect bar portion and located between the third and the second erect bar portions. A first gap is between the first and third erect bar portions, and a second gap is between the second and fourth erect bar portions. The bottom rib section connects at least portion of the bottom ends of the first, second, third and fourth erect bar portions, and the first and second gaps are each formed with an opening at the end opposite to the bottom rib section.

Abstract: A stirrup module comprising an outer stirrup set, an upper-opening stirrup set having an upper opening and provided in an opening of the outer stirrup of the outer stirrup set, and a lower-opening stirrup set having a lower opening and provided in the opening of the outer stirrup of the outer stirrup set. Wherein the upper opening and the opening of the outer stirrup are oriented in the same direction, the lower opening and the upper opening are in opposite directions to each other. Wherein the upper-opening stirrup set has a first bottom of stirrup opposite to the upper opening, and the first bottom of stirrup corresponds to the position of the lower opening; the lower-opening stirrup set has a second bottom rib opposite to the lower opening, and the second bottom rib corresponds to the position of the upper opening.
