Description
Technical Field
The utility model relates to a reinforced concrete structure construction field especially relates to a steel bar connector is pressed in tensile.
Background
The construction of the reinforced concrete structure is beneficial to, the steel bars are generally connected, the connection mode of the steel bars mainly comprises four connection modes of binding and lapping, mechanical connection, sleeve grouting connection and welding, the joint strength of the steel bars is generally higher than that of a steel bar base metal, and the steel bar reinforced concrete structure has the advantages of high connection speed, environmental friendliness, steel saving and the like.
In the regulation of concrete structure design code: the longitudinal stressed steel bars of the axial tension and small eccentric stressed rod piece can not adopt binding lap joints. When the diameter d of the tension steel bar is larger than 25mm and the diameter d of the compression steel bar is larger than 28mm, the binding lap joint is not suitable.
The types of steel connecting sleeves commonly used in the market are as follows:
(1) taper thread adapter joint: the joint is formed by meshing a specially-made tapered thread at the end of the steel bar and a tapered thread of a connecting piece. However, tapered threaded joints are of poor quality. Because the small diameter of the machined thread weakens the cross-sectional area of the parent metal, and then the joint strength is reduced, the practical tensile strength of the parent metal can only be reached to 85-95%.
(2) Straight thread adapter: the straight thread adapter mainly comprises an upsetting straight thread adapter and a rolling straight thread adapter. Upsetting the straight thread adapter: the straight thread made after the steel bar end is upset is meshed with the thread of the connecting piece to form the joint. The process comprises the following steps:
the end of the steel bar is upset by upsetting equipment, and then a thread is processed, wherein the small diameter of the thread is not less than the diameter of the steel bar base metal, so that the strength of the joint and the base metal is equal. The end of the steel bar of the foreign upsetting straight thread adapter has hot upsetting and cold upsetting. Hot upsetting is mainly to eliminate the internal stress that occurs during upsetting, but the heating equipment investment is high. In the upsetting straight thread adapter joint in China, the end of a steel bar is mainly subjected to cold upsetting, the ductility requirement on the steel bar is high, and the upsetting quality of the steel bar with low ductility is difficult to control. The heading deviation appearance is easy to appear in the heading process, and once heading deviation is generated, the heavy heading is cut off; the internal stress is generated in the upsetting process, the plasticity of the steel bar is reduced after upsetting, the brittle fracture appearance is easy to occur, and two processes are required for thread processing and two sets of equipment are finished.
Rolling the straight thread adapter: the joint formed by meshing the straight threads and the connecting piece threads is manufactured by directly rolling or extruding (rolling) the end of the steel bar to roll or peeling the ribs and then rolling, and the process and the equipment are complex.
(3) Kneading the adapter by the sleeve: the plastic deformation of the steel sleeve of the connecting piece is tightly engaged with the ribbed steel bar through kneading force to form the joint. There are two methods, radial kneading engagement and axial kneading engagement. The axial kneading connection is inconvenient to construct on site and poor in joint quality, and is not pushed; the radial kneading and connecting technology can be used for large-area pushing and applying of the connecting joint. The sleeve kneading adapter joint is adopted to connect two reinforcing steel bars, construction can be completed only by special tools and a hydraulic system, and the field construction speed is low for a large number of fields needing reinforcing steel bar connection.
In the process of connecting two reinforcing steel bars by using the reinforcing steel bar connecting sleeve, the thread machining is prefabricated in advance and processed on site, the transverse ribs and the longitudinal ribs of the reinforcing steel bars need to be processed in the thread machining, the diameter of a cylinder body before the thread rolling of the reinforcing steel bars reaches the same size, then the thread machining is carried out, two procedures are carried out, and two sets of equipment are completed. The disadvantage of welding is that it requires a high skill from the operator and is generally only suitable for joining steel bars of the same diameter.
Among the prior art, two structures about mechanical connection adopts, the left and right sides of two structures all realizes the scheme of connecting through the bolt, because the steel bar connection department receives the pulling force, pressure and resistance to shear, the atress condition is complicated, and the structure of whole piece, in order to guarantee the atress equilibrium, it is higher to whole piece manufacturing requirement, in case whole piece structure has one or more bump, in the centre gripping process, only the bulge part takes place the contact with the reinforcing bar, thereby cause clamping strength not enough, and the structural flexibility of whole piece is poor, also have the requirement to the clamping dynamics equilibrium, otherwise lead to the clamping-force relatively poor, and be not applicable to the connection of not unidimensional reinforcing bar, the block reinforcing bar effect is poor, only rely on the bolt to realize the connection, connection stability is relatively poor, cause two steel bar connection's the.
In summary, in the construction industry, the conventional steel bar connection methods such as overlapping, welding and the like cannot meet the requirement of rapid development of the construction industry from the aspects of connection quality, efficiency and operability. The lap joint connection mode cannot be used for connecting large-size steel bars, and welding has many defects (such as unstable steel materials, poor weldability and the like, unstable power supply or poor welder level, short construction period, insufficient capacitance, weather influence caused by wind, rain and cold and the like, a construction scheme of a place with high fireproof requirements, and the on-site connection quality and speed of the horizontal steel bars) and welding quality cannot be guaranteed.
