Background

With the rapid development of Chinese capital construction, the reinforcement cage is widely applied as an important component of a building construction member. Generally, when a bridge or a culvert or a high-rise building is constructed, a ground foundation is required to be piled, specifically, a machine is used for punching or a water mill is used for drilling a deep hole, the hole depth reaches the design requirement, then a reinforcement cage is placed in the deep hole, and finally concrete pouring is carried out.

For some overlong pile holes, the model of the overlong reinforcement cage needs to be matched, when the length of the reinforcement cage is longer (generally more than 30 meters), the reinforcement cage needs to be manufactured in a segmented mode, the reinforcement cage can be manufactured in multiple segments because the longer reinforcement is inconvenient to transport, and then the reinforcement cage in different segments is integrally butted on a construction site.

The butt joint of the reinforcement cage in the prior related art is mainly divided into the following three types, (1) welding: the main reinforcements at the opposite ends of the two reinforcement cages are welded one by one, but the welding is greatly influenced by external factors, such as unstable power supply, unexpected weather and the like in the welding process; (2) lapping: the lap joint is that lap joint steel bars are used as a connecting bridge between two steel bar cages, and the two steel bar cages are connected by steel wire binding, indirect spot welding and the like, so that the lap joint steel bars are wasted, and a large amount of raw materials are wasted; (3) and (3) sleeve connection: namely, external threads are machined at the opposite ends of the upper main rib and the lower main rib, and then the upper main rib and the lower main rib are connected through a straight thread sleeve.

The method is characterized in that the sleeve is connected with the steel reinforcement cage in a sleeved mode, wherein the sleeve is connected with the steel reinforcement cage in a highest strength mode, and is also the most stable and safe connection mode.

However, the construction method consumes time and labor, 2-3 construction workers are required to perform screwing operation during normal construction, the time consumed in the whole screwing process accounts for more than 70% of the installation time of the whole reinforcement cage, and the whole construction progress of the butt joint of the multiple sections of reinforcement cages is greatly reduced.
