Abstract
The utility model discloses a steel hoop for a prestressed reinforced concrete well pipe, which is formed by bending and soldering a section strip. The utility model is characterized in that ditches, slots, stages and beveled circular rings with different purposes are arranged on the certain location, wherein such as picture one, 1 is a tensive and tensile slot which enables two embedded iron with right-angle trapezoid inner cross sections are inserted into the slot, and the two embedded iron is connected by a side shaft and connected with a tensive and tensile device to reach an aim of stretching and dragging; 2 is a soldering divided edge with pipe ports to the pipe ports; 3 is a steel wire stretching bed, which enables the steel wire behind a pile head to pass through a hole to reach the aim of stretching and dragging; 4 is an oblique angle of a steel hoop, which enlarges the contact face between the steel hoop and the concrete, increases the gripping force, and saves raw materials; picture two is a top plan view of the steel hoop. Compared with the prior art, the utility model has the advantages of labor saving, time saving, material saving, good quality and high strength.
Description
Technical field
The utility model relates to a kind of prestressed reinforced concrete well casing stirrup.
Background technology
Former prestressed reinforced concrete well casing stirrup, all adopting thickness is the hot band steel of 8mm one-level, through cut off, curved circle, welding, shaping, cylindrical turning stretch-draw mouth, interior usefulness 12 * 12mm square steel embed to justify in the stirrup through bending after and be welded into the high tensile steel wire stretching bed, beat operation such as threaded hole of steel and be made, technology is numerous and diverse, is difficult for ensuring the quality of products; The waste raw material and the energy; Time-consuming; And owing to there is not groove, solder failure may appear when becoming under the pipe rear overhang hanging in the pipe process mouth of pipe butt welding.The utility model overcomes the deficiency of above-mentioned technology exactly, a kind of saving of labor is provided, saves time, easily processing, reliable quality prestressed reinforced concrete well casing stirrup.
Summary of the invention
A kind of prestressed reinforced concrete well casing stirrup is characterized in that having ditch at certain position, groove, and the circular stirrup on platform hole and inclined-plane, groove is used for stretch-draw, and the platform hole is used to wear the steel wire behind the pier nose, and the inclined-plane is used for welding or increases bond stress.
Description of drawings
Fig. 1 looks full sectional drawing for the master of pipe stirrup;
Fig. 2 is the vertical view of pipe stirrup.
1 is the stretch-draw groove among the figure, the 2nd, and pipe port is to the bevel for welding of pipe port, and the 3rd, steel wire stretching platform, the 4th, stirrup oblique angle.
The specific embodiment
Technical solution of the present utility model is to adopt a kind of homemade special-shaped band steel to form through curved circle, welding, punching.The utility model carries groove owing to adopted the self-control abnormal shape to be with steel behind the one-tenth hoop, line up is welded become easy and increased weld strength; Owing to become hoop to carry the stretch-draw groove, so saved machined into; Since carry the stretching bed of steel wire, operations such as the curved circle of the steel band of 12 * 12mm, welding saved, and increase the bulk strength of stirrup; Owing to become the side-lower of hoop back hoop that an inclined-plane is arranged, thus hoop and concrete contact area increased, thereby increased grip and wrap up in power, increased the bulk strength of well casing.
