1. Brief introduction of self climbing concrete placing boom
Traditional cloth machine has 360 ° inversion arm posture cloth, rotate the operation is simple and sensitive, it is of high efficiency, energy saving, it is economical, and useful. But in high-rise buildings, especially those requiring rapid construction, the traditional spreader is not so convenient and needs to be hoisted after each layer of pouring to facilitate the construction of the next layer. The self climbing concrete placing boom is equipped with automatic climbing mechanism, which can automatically climb in the elevator shaft by hydraulic cylinder jacking, so that the feeder increases with the rise of the floor. The self climbing concrete placing boom is placed on the working face of the structure, which greatly improves the efficiency and quality of concrete work, ensures safety, reduces labor and has great promotion value.
The technology has been successfully applied to the Zhongjian straits business plaza project. The upper main structure solves the problems of slow concrete pouring and difficult concrete pouring of beam-column joints through the application of self-climbing concrete spreader. The standard floor pumps is about 40.3 cubic meters of concrete per hour. While improving the concrete casting and ramming efficiency and ensuring the quality of concrete construction, the main structure was capped 35 days in advance, which well realized the rapid construction.
