Description
Technical field
The invention belongs to concrete square pile technical field, particularly relate to a kind of reinforced bar skeleton seam welder, Making of reinforcement cage method and square pile manufacture method.
Background technology
Prefabricated Reinforced Concrete Square Pile is pile foundation material important in China's civil construction foundation engineering, a kind of concrete product that in Ye Shi China prefabricated components, yield is bigger. Prefabricated Reinforced Concrete Square Pile product has the following characteristics that concrete strength of pile is higher, and single pile bearing capacity of pile is bigger; Construction is affected less by groundwater change; Make facility, both can in-situ precast, it is also possible to factorial praluction; The stake of all size and length according to different geological conditions, can be produced; Pile quality is reliable, and construction quality is prone to ensure than bored concrete pile; Speed of application is fast, and the scale of investment of building of production line is less. In recent years, along with the development of Building Trade in China, this product a lot of areas at home obtain development energetically.
Framework of steel reinforcement is as the ingredient of Prefabricated Reinforced Concrete Square Pile, and its composition, quality and structural strength etc. directly affect the quality of Prefabricated Reinforced Concrete Square Pile. The prestressed concrete square pile applied in the market is all the hollow pile of centrifugal forming mostly, adopt steel bar for prestressed concrete as main muscle, it is that building field is a large amount of, widely used because of advantages such as production efficiency rigidity of soft tissues degree high, main are of a relatively high, concrete strength is high, the cycle is very fast, and continue up use so far, in current conventional piles basis, occupy critical role. But, in production and application process, main muscle adopts the prestressing concrete hollow pile of rod iron to there is more problem. For the ease of stretch-draw in production, the hot pier nose technology of rod iron must be adopted, this pier nose and pile body end plate, stretch board are blocked and carries out prestressed stretch-draw, it is impaired that the pier nose part of hot this rod iron of pier can cause that the intensity of rod iron is undermined material, simultaneously, owing to rod iron pier nose precision is inconsistent, cannot be fully contacted with end plate during stretch-draw, cause end plate local failure; Rod iron controls not, to cause that rod iron length differs, there will be Stress non-homogeneity in stretching process due to cutting accuracy, the phenomenon even broken.It addition, need the operations such as centrifugal forming, high-temperature steam curing in producing, cause complex process. Prestressing concrete hollow pile mechanical property is better, but because rod iron fragility is high, cause that overall fragility is obvious, bending resistance and shear behavior are not enough, when disaster occurs, escape and rescue time are relatively short, are unfavorable for personnel escape, for security consideration, China much areas have started to forbid use prestressing concrete hollow pile in some pile foundation engineering.
Prestress wire is widely used in bridge, building, water conservancy, the energy and Geotechnical Engineering etc. because possessing the intensity high feature good with relaxation property. In recent years, steel strand wires are applied to prestressed-concrete pile and have carried out substantial amounts of research by China, but are only a kind of technology design mostly, it does not have be formed with the technical scheme of practical value. Using prestress wire as the main muscle of prefabricated pile prestressing force, high than the reinforcement of concrete prestressed steel bar intensity, ductility is good, but in actual applications, there is also distinct issues: one is steel strand wires is formed by many steel wires are stranded, not easily welding, be not easily wound around, the framework of steel reinforcement that prefabricated pile is made up of framework of steel reinforcement not easily makes; Two to be that while to be applied in the technics comparing of the aspect steel strand prestress stretch-draw such as bridge ripe, but is applied in the aspect of prefabricated pile, and but research is few, relate generally to how by steel strand anchoring, stretch-draw, put and put each technological processes such as a follower head process.
Existing compound reinforcement prestressed concrete stake, the main muscle of its prestressing force mostly adopts steel bar for prestressed concrete, small part adopts steel strand wires, adopt steel strand wires as the compound reinforcement prestressed concrete stake of the main muscle of prestressing force, all without the manufacture method finding suitable framework of steel reinforcement, could not solve steel strand wires cannot the difficult problem of roll welding. The manufacture method of the framework of steel reinforcement of existing compound arrangement of reinforcement is all first adopt the standby framework of steel reinforcement basic framework being made up of non-prestressed main muscle of framework of steel reinforcement automatic seam-welding mechanism, it is ready for tensioning equipment, ground tackle, in framework of steel reinforcement, penetrate the main muscle of prestressing force according to distributed steel requirement, main for prestressing force muscle is fixed on tensioning equipment and fixes with ground tackle. Installing and colligation it is to say, non-prestressed main muscle and the main muscle of prestressing force are by substep in the process constituting framework of steel reinforcement, why substep carries out, a big chunk reason is because existing prestressing force main muscle especially prestress wire cannot roll welding. But the manufacturing process that substep carries out framework of steel reinforcement wastes time and energy, and efficiency is very low.
As can be seen here, prior art awaits further improving.
