The two pre-grouped steel cages are grouped together. As described above, the two main ribs 40 can be brought together by screwing the first joint portion 42 and the second joint portion 44 of the two main ribs 40. The assembly of the two pre-grouped steel cages can be accomplished by joining together a plurality of main ribs 40.

In the present creation, since the main rib 40 and the working rib 30 are disposed in the second stirrup 20, and the second stirrup is the first hoop with the working rib 30 and/or the end by the detachable fixing member 60 The ribs 18 are temporarily fixed together. Therefore, after the detachable fixing member 60 is removed, the second stirrup 20 can be moved to the main rib 40 and the working rib 30 of the other pre-group reinforcing cage so that the second stirrup 20 is sleeved on the other The main ribs 40 of the group of steel cages and the working ribs 30. Thereby, the assembly strength of the two pre-group reinforcing cages can be improved.

In summary, the pre-grouped steel cages and their manufacturing methods of the present invention adopt pre-assembled construction methods of pre-grouped steel cages, without the need to set up a scaffolding, which can reduce the risk and shorten the construction time by one to three times. Moreover, the equipment can be set in advance, which is conducive to control the construction progress and quality, and is not affected by the weather on the construction site. When assembling the pre-group reinforcement cage with the main reinforcement of another pre-group reinforcement cage at the construction site, the main reinforcement can be combined with the main reinforcement of another pre-group reinforcement cage by rotating the main reinforcement of the pre-group reinforcement cage. It is not affected by the positional deviation of the main reinforcement of the pre-grouped cage and the main reinforcement of the other pre-group reinforcement cage, which can improve the quality of the pre-group reinforcement cage and reduce the time and operation cost. And because one of the main ribs is limited to the accommodating space by the limiting member, when the pre-assembled reinforcing cage is moved, the main rib passing through the first stirrup is not separated from the first stirrup. It can improve the flexibility and stability of the pre-group reinforcement cage.

The above is intended to be illustrative only and not limiting. Any equivalent modifications or alterations to the spirit and scope of this creation shall be included in the scope of the appended patent application.
