Description
Technical Field
The utility model belongs to the technical field of civil engineering construction bar reinforcement engineering, more specifically say, relate to a steel pipe concrete wears post magnetism positioning clamp device for reinforcing bar.
Background
With the large-scale construction of industrial civil buildings in China, civil engineering construction technology is developing vigorously, and novel structural forms are emerging continuously. Compared with a steel structure, the steel pipe concrete column and reinforced concrete beam plate combined structure has the advantages of high bearing capacity, good anti-seismic performance, high construction efficiency and high industrialization degree, has the advantages of good stability and high rigidity, and is more and more widely applied to a plurality of multi-story and high-rise structures.
The connection joint of the steel pipe concrete column and the reinforced concrete beam is complex in structure, and the quality control of welding is difficult due to the influence of construction operation space. Therefore, in the industry, a connecting structure is provided, in which anchor bars are embedded in a steel pipe column, a steel corbel support is arranged at the lower part of a beam end, and the beam end is lapped by steel bars and post-cast with concrete. The structure is simple in connection and less in welding workload, the arrangement of the support bracket not only improves the shearing-resistant bearing capacity of the beam end, but also can move the plastic hinge of the beam end to the outside of the support bracket range, the beam hinge mechanism is more obvious, and the ductility performance of the structure is improved. The anchor bars in this construction are extended into the steel pipe to achieve firm anchoring by the cohesive force of the concrete in the pipe, and thus should have a sufficient anchoring length. When concrete is poured in the pipe, the position of the steel bar is changed due to the falling and vibration of the concrete, and the anchoring effect is affected. Therefore, measures should be taken to fix the anchoring position of the reinforcing bars in the columns.
Before concrete is poured, a conventional method for fixing the steel bars is to spot weld the steel bars to steel bar orifices on the steel tubes, the method seriously influences the stress uniformity of the hollow steel tubes and generates stress concentration, and meanwhile, when the steel bars are pulled, the tube wall locally deforms outwards, so that the local part of the steel tube wall is separated from the concrete in the tube, the constraint effect on the concrete in the tube is influenced, and the bearing capacity is reduced.
Make reinforcing bar and pore wall contactless during use usually, during reinforcing bar pulling force then can directly transmit intraductal concrete, reinforcing bar atress performance is better. The method adopted by the method is as follows: and (4) winding the anchor bars extending out of the surface of the square steel pipe by using iron wires, and connecting the anchor bars into a whole to fix the positions of the anchor bars. The method for fixing the steel pipe by the iron wire is insufficient in provided constraint force, the problem that anchor bars shake in a certain angle to cause anchor position deviation cannot be solved, and meanwhile, the problem that the anchor bars wholly deviate along the surface of the vertical steel pipe to cause insufficient anchor length can be caused due to the fact that the iron wire is connected. In addition, the iron wire is wound, which wastes labor and time, cannot be repeatedly used and has poor effect. Therefore, a magnetic positioning clamp device capable of effectively positioning the concrete filled steel tube column-penetrating steel bar is urgently needed to be designed.
Through retrieval, a great number of patents have been published on the technical application of the magnetic positioning clamp device for the steel bar, such as the Chinese patent application numbers: 2018218739990, the name of invention creation is: the application discloses a magnetic positioning device for exposed steel bars of energy-saving prefabricated members, which comprises a quantifying device, wherein the quantifying device comprises a connecting part, a base plate and a sleeve, the base plate is flat, the connecting part is fixedly arranged on one side surface of the base plate, and the sleeve is detachably and vertically connected to the other side surface of the base plate; the magnetic support is in a square column shape and is connected with the quantifying device through a connecting part, and the sleeve is perpendicular to the magnetic support. This application can freely adjust positioner position and expose reinforcing bar length according to the component size, and integrated device weight is lighter, makes things convenient for manual operation, because a whole when positioner in the use, has avoided the error that artificial disturbance brought, when fixed exposure size product of bulk production, can have higher efficiency, realizes fool's operation basically, effectively improves the operating quality of construction.
