Then the second stirrup 20 is temporarily fixed on the working bar 30 and/or the first stirrup 18 at the end by the detachable fixing part 60 (step S70), and the production of the pre-assembled reinforcement cage of the present utility model is completed . Preferably, in practice, the second stirrup 20 is temporarily fixed together with the endmost first stirrup (for example, the first stirrup 18 in FIG. 1 ) by the detachable fixing member 60 . Similarly, the number of the second stirrup 20 is not limited, and when the second stirrup 20 is to be used in practice, that is to say, when the position of the second stirrup 20 is adjusted to an appropriate position, the detachable type fastener 60. The number of the second stirrups 20 may be one or more, for example, and the number is not limited thereto. Users can adjust the quantity according to actual needs.

Because the utility model adopts the construction method of pre-assembled pre-assembled steel cages, it can avoid the danger of scaffolding in known building construction, and the utility model can shorten the construction time more than the traditional construction method. Moreover, by pre-assembling the pre-assembled steel cages, materials can be prepared and assembled in advance, and construction does not need to wait for the floor to be completed. Not only is it not affected by the weather on the construction site, but it is also conducive to controlling the construction progress, quality and reducing construction costs.

After completing the fabrication of the preassembled reinforcement cage, the user can move the preassembled reinforcement cage to the construction site, and by connecting the main reinforcement 40 with the main reinforcement 40 on the floor (such as the main reinforcement of another preassembled reinforcement cage), And the two pre-assembled reinforcement cages are connected together. As mentioned above, the first joint portion 42 and the second joint portion 44 of the two main ribs 40 can be screwed together so that the two main ribs 40 can be assembled together. The assembly of two preassembled reinforcement cages can be completed by connecting multiple main reinforcements 40 together.

In the present utility model, because the main reinforcement 40 and the working reinforcement 30 are set in the second stirrup 20, and the second stirrup is connected with the working reinforcement 30 and/or the first end of the end by the detachable fixing part 60. The stirrups 18 are temporarily held together. Therefore, after removing the detachable fixing part 60, the second stirrup 20 can be moved to the main reinforcement 40 and the working reinforcement 30 of another pre-assembled steel cage, so that the second stirrup 20 is sleeved on another pre-assembled reinforcement cage. On the main reinforcement 40 and the working reinforcement 30 of the group reinforcement cage. Thereby, the assembly strength of the two preassembled reinforcement cages can be improved.

To sum up, the pre-assembled steel cage and its manufacturing method of the present invention adopt the construction method of pre-assembled pre-assembled steel cage without scaffolding, which can reduce the risk and shorten the construction time by 1-3 times. In addition, materials can be assembled in advance, which is beneficial to control the construction progress and quality, and is not affected by the weather on the construction site. When assembling the pre-assembled reinforcement cage with the main reinforcement of another pre-assembled reinforcement cage on the construction site, by rotating the main reinforcement of the pre-assembled reinforcement cage so that the main reinforcement can be combined with the main reinforcement of another pre-assembled reinforcement cage, It is not affected by whether the main reinforcement of the pre-assembled reinforcement cage has a position deviation from the main reinforcement of another pre-assembled reinforcement cage, which can improve the quality of the pre-assembled reinforcement cage and reduce time and operating costs. And because a section of the main reinforcement is limited in the accommodating space by the limiting member, when the pre-assembled reinforcement cage is moved, the main reinforcement passing through the first stirrup will not be separated from the first stirrup, It can improve the flexibility and stability of the pre-assembled reinforcement cage.

The above description is for illustration only, not for limitation. Any equivalent modification or change made without departing from the spirit and scope of the present utility model shall be included in the appended claims.
