The production method of prestressed concrete square pile steel skeleton roller welding machine
Prestressed concrete pile is a kind of prestressed concrete prefabricated parts made by using pretensioning process and centrifugal forming method through steam curing, which has the advantages of strong single pile bearing capacity, large friction coefficient, low cost, easy to use and convenient for standardization, etc., and has been paid more and more attention by people. In the past, China in the manufacture of prestressed concrete pile reinforcement skeleton, most of the production method using manual tying or welding, so that not only labor intensity, low production efficiency, and the quality of the product can not be guaranteed, since the reform and opening up, especially in recent years, with the port, bridge, high-rise building business booming development, the demand for prestressed reinforced concrete pile gradually increased, the quality of the pile According to the market needs, in the early years, our factory had researched and developed one of the main equipment for prestressed concrete piles-prestressed concrete pipe pile steel skeleton roller welding machine, and obtained the patent of microcomputer-controlled Cage Welding Machine for reinforced concrete piles, pipes and rods. The object of use of the patent is cylindrical prestressed concrete pipe piles. The prestressed concrete square pile reinforcement skeleton differs from the round cross section of the prestressed concrete pipe pile reinforcement skeleton due to its square cross section and the unequal distance of its centre point to the periphery. Therefore, the prestressed concrete square pile welding machine is difficult to achieve mechanised automatic welding production. Prior to the publication of this patent application, the production of prestressed concrete square pile steel skeleton in China can only be produced by hand-tying or by manual welding, which is not only labour-intensive and inefficient, but also cannot guarantee the quality. Due to the high quality requirements of buildings for prestressed concrete square piles, hand-tied or hand-welded prestressed concrete square pile steel skeletons not only cannot meet the needs of construction development in terms of quantity, but more importantly, the quality cannot meet the engineering specifications, thus hindering the development of prestressed concrete square piles for a long time. The research and development of one of the main equipment of pre-stressed concrete square pile - pre-stressed concrete square pile steel skeleton roller welding machine, will play a positive role in the development of Pile Cage Welding Machine.
