Description

A networked prestressed high-strength concrete pipe pile networked reinforcement cage roll welding system device

technical field

The invention belongs to the technical field of prestressed high-strength concrete pipe pile reinforcement cage rolling welding device, and relates to a new type of mesh reinforcement cage rolling welding system device, especially the system device can complete the preparation of mesh reinforcement cage in two steps, and The degree of automation is high, and the processes of steel bar straightening, arrangement in the drum, welding, cutting, etc. are all automatically completed by the cooperation of various devices. At present, the rolling welding machine for the spiral steel bar cage cannot complete the weaving work of the reticulated steel bar and has low efficiency. The device of the present invention not only successfully solves the weaving work problem of the reticulated reinforcing bar cage but also has higher efficiency.

Background technique

The pile foundation using prestressed high-strength concrete pipe piles is an excellent foundation form, but due to insufficient research on the seismic performance of pipe piles, the scope of application of pipe piles stipulated in the current code is "non-seismic areas and seismic fortification intensity less than or equal to 8 The low cap pile foundations of industrial and civil buildings, structures and other projects in high-intensity areas should be used with caution when the seismic fortification intensity is 8 degrees and the construction site category is Ⅲ or Ⅳ. The application of pipe piles is limited. Therefore, the prestressed high-strength concrete pipe piles with superior seismic performance not only make the pile foundation, an excellent foundation form, better applied to engineering structures, but also further solve the complex geological environment and large-scale engineering structure foundation problems.

The reticular prestressed high-strength concrete pipe pile is a new type of pile, which is a new product obtained by adjusting the reinforcement form of the prestressed high-strength concrete pipe pile. It has very superior seismic performance and will have a wide range of application space. But the steel cage roll welding machine in the production field at present is all aimed at the spiral stirrup form and can not solve this special steel cage form of reticular reinforcement. In view of this, we invented a mesh steel cage roll welding system device to solve this problem, and the device has the advantages of high automation and high efficiency.
