Description
Technical Field
The utility model relates to the field of tensioning devices, in particular to a reinforcement cage prestress tensioning device.
Background
The precast reinforced concrete square pile is an important pile foundation material in civil construction foundation engineering, and is also a concrete product with larger yield in precast components. The precast reinforced concrete square pile product has the following characteristics: the pile body concrete strength is high, and the bearing capacity of a single pile body is high; the construction is less influenced by the change of groundwater; the manufacturing is convenient, and the method can be prefabricated on site and can also be used for industrial production; piles of various specifications and lengths can be produced according to different geological conditions; the pile body quality is reliable, and the construction quality is easier to guarantee than that of the cast-in-place pile; the construction speed is high, the investment scale of the production line construction is small, and the like. In recent years, with the development of the construction industry, the product is greatly developed in many areas in China.
The reinforcement cage is used as a component part of the precast reinforced concrete square pile, and the composition, the quality, the structural strength and the like of the reinforcement cage directly influence the quality of the precast reinforced concrete square pile. The prestressed concrete square piles applied to the current market are mostly hollow piles formed by centrifugation, and steel bars for prestressed concrete are adopted as main reinforcements, so that the prestressed concrete square piles are widely and widely used in the building field due to the advantages of high production efficiency, relatively high main reinforcement strength, high concrete strength, relatively fast period and the like, and continue to be used until now, and play an important role in the current traditional pile foundation. However, there are many problems with prestressed concrete hollow piles in which steel bars are used as the main bars during the production and use. In order to facilitate tensioning in production, a steel bar hot pier head technology is adopted, the pier head, a pile body end plate and a tensioning plate are clamped for prestress tensioning, the strength and the material of the steel bar can be damaged due to the fact that the pier head part of the steel bar is hot, meanwhile, the precision of the steel bar pier head is inconsistent, the steel bar pier head cannot be fully contacted with the end plate during tensioning, and the end plate is locally damaged; the steel bar has different lengths due to insufficient cutting precision control, and uneven stress and even stretch-breaking can occur in the tensioning process. In addition, the production requires procedures such as centrifugal molding, high-temperature steam curing and the like, which results in complex process. The prestressed concrete hollow pile has good mechanical properties, but because of the high brittleness of the steel bar, the whole brittleness is obvious, the bending resistance and the shearing resistance are insufficient, when disasters occur, the escape and rescue time is relatively short, the escape of personnel is not facilitated, and for safety reasons, the use of the prestressed concrete hollow pile in certain pile foundation engineering is forbidden in many areas.
The prestressed steel strand has the characteristics of high strength and good relaxation performance, and is widely applied to bridges, buildings, water conservancy, energy sources, geotechnical engineering and the like. In recent years, a great deal of research has been conducted on the application of steel strands to prestressed concrete piles, but most of them are only one technical concept, and no practical technical solution is formed. The prestressed steel strand is used as a prestressed main rib of the precast pile, and compared with a prestressed steel rod for concrete, the prestressed steel strand has high strength and good ductility, but in practical application, the prestressed steel strand also has the outstanding problem: firstly, a steel strand is formed by twisting a plurality of steel wires, so that the steel strand is not easy to weld and wind, and a steel reinforcement cage formed by the steel reinforcement cages of the precast pile is not easy to manufacture; secondly, although the process of prestress tensioning of the steel strand applied to bridges and the like is mature, the process of prestress tensioning of the steel strand applied to precast piles is not researched much, and mainly relates to various process flows of anchoring, tensioning, end treatment after releasing Zhang Ji of the steel strand and the like.
Therefore, how to realize prestress tensioning of each reinforcement bar for a reinforcement cage in a composite reinforcement bar form is a technical problem to be solved in the field. Therefore, it is necessary to invent a tendon cage prestress tensioning device to solve the above problems.
