Problems solved by technology

Using prestressed steel strands as the prestressed main reinforcement of prefabricated piles has higher strength and better ductility than prestressed steel rods for concrete, but in practical applications, there are also prominent problems: first, the steel strands are twisted by multiple steel wires It is not easy to be welded and entangled, and the steel skeleton composed of prefabricated piles is not easy to make; second, although the prestressed tensioning technology of steel strands used in bridges and other aspects is relatively mature, it is not easy to apply to prefabricated piles. There are not many studies, which mainly involve how to anchor the steel strand, stretch it, release it, and treat the end after it is stretched.
That is to say, the non-prestressed main reinforcement and the prestressed main reinforcement are installed and bound step by step in the process of forming the steel skeleton. A large part of the reason for the step by step is because the existing prestressed main reinforcement, especially the prestress Steel strands cannot be seamed
However, the step-by-step manufacturing process of the steel skeleton is time-consuming and laborious, and the efficiency is very low.

Abstract

The invention discloses a steel reinforcement framework seam welder, a steel reinforcement framework manufacturing method and a square pile manufacturing method. The seam welder comprises a fixed rotating electrode mechanism, a fixed immovable electrode mechanism and a pulling frame. The fixed immovable electrode mechanism is disposed below the fixed rotating electrode mechanism and used for performing welding positioning on non-prestressed main reinforcements and performing isolation guiding on steel strands. The pulling frame is disposed in rear of the fixed immovable electrode mechanism and used for pulling the non-prestressed main reinforcements and the steel strands. The manufacturing method of the steel reinforcement framework includes the step that the steel strands are synchronously pulled while welding positioning is performed on the non-prestressed main reinforcements and reinforcement stirrups through the seam welder. The method for manufacturing a prestressed concrete square pile includes the steps of manufacturing the steel reinforcement framework, tensioning the steel strands, pouring concrete, performing curing and paying off and tensioning the steel strands. The steel reinforcement framework and the square pile are conveniently and rapidly manufactured through the seam welder in the invention, and the production efficiency is high.

Description

technical field [0001] The invention belongs to the technical field of concrete square piles, and in particular relates to a steel frame rolling welding machine, a method for manufacturing a steel frame and a method for making square piles. Background technique [0002] Prefabricated reinforced concrete square pile is an important pile foundation material in my country's civil and architectural foundation engineering, and it is also a concrete product with a large output in my country's prefabricated components. The prefabricated reinforced concrete square pile products have the following characteristics: the concrete strength of the pile body is higher, and the bearing capacity of the single pile body is larger; the construction is less affected by the change of groundwater; Different geological conditions can produce piles of various specifications and lengths; the quality of the pile body is reliable, and the construction quality is easier to guarantee than cast-in-situ p...
