Detailed Description
The following description is made with reference to the accompanying drawings and examples, but not to be construed as limiting the invention.
The embodiment of the utility model provides a: an annular hoop for a bridge pier stud outer-wrapped steel protective cylinder is shown in attached figures 1-3, a steel protective cylinder 2 is formed by fixedly connecting a plurality of circular arc-shaped steel plates with the same structure in an annular sequence, a plurality of groups of reserved bolt holes 5 are formed in each circular arc-shaped steel plate along the length direction of the circular arc-shaped steel plate at intervals, each group of reserved bolt holes 5 is formed by a plurality of reserved bolt holes 5 which are arranged on the periphery of each circular arc-shaped steel plate in an annular mode and are located on the same horizontal plane, 1 circular arc-shaped hoop 1 is arranged on the outer wall of the circular arc-shaped steel plate at the position of each group of reserved bolt holes 5, the end portions of adjacent circular arc-shaped hoops 1 are connected together to form a circular ring, a plurality of bolts 3 are connected to each circular arc-shaped hoop 1, the arrangement positions of the bolts 3 on the circular arc-shaped.
In the process of processing the circular arc steel plate, the steel casing 2 is evenly divided into a plurality of circular arc steel plates according to the size of the steel casing, wherein the number of the circular arc steel plates can be 2, 3, 4 or other numbers. The steel casing 2 with a cylindrical structure is formed just after the circular arc-shaped steel plates are connected in sequence. The circular arc-shaped steel plate is formed by winding a flat steel plate, and the circular arc-shaped structure cannot be guaranteed in the winding process, so that the steel casing 2 with the cylindrical structure cannot be guaranteed in the later assembling process of the circular arc-shaped structure, and the reserved bolt holes 5 are formed in the circular arc-shaped steel plate. Because the structure of the circular arc-shaped hoop 1 is fixed to be circular arc-shaped and the rigidity of the circular arc-shaped hoop is good, the processed circular arc-shaped steel plate is fixed with the circular arc-shaped hoop 1 through the bolt 3, and the outer surface of the circular arc-shaped steel plate is attached to the inner surface of the circular arc-shaped hoop 1 by tightening the nut on the bolt 3, so that the shape of the circular arc-shaped steel plate is fixed and the circular arc-shaped structure is kept. In the mutual stacking process of the arc-shaped steel plates, the arc-shaped hoop 1 cannot deform under the action of external force extrusion due to high rigidity of the arc-shaped hoop 1, so that the original roundness and flatness of the arc-shaped steel plates connected with the arc-shaped hoop are guaranteed in the transportation and subsequent installation processes.
In the use process, the plurality of arc-shaped steel plates are arranged on the outer wall of the bridge pier stud, and then the head ends of the adjacent arc-shaped hoops 1 are fixedly connected together, so that the arc-shaped hoops 1 are sealed into a ring, so that the arc-shaped steel plates connected with the arc-shaped hoops also form a ring in an annular mode, and then the adjacent arc-shaped steel plates are fixed together through welding, so that the plurality of arc-shaped steel plates finally form the steel casing 2. And finally, adjusting the verticality of the steel casing to finish the installation.
After the steel protects a section of thick bamboo installation, can be provided with the reinforcing bar between steel protects a section of thick bamboo and bridge pier stud, then concreting to accomplish the maintenance reinforcement of bridge pier stud and improve bearing capacity. The bolt 3 can be twisted off in the later stage to separate the circular arc-shaped hoop 1 from the circular arc-shaped steel plate, and the circular arc-shaped hoop 1 can be repeatedly used.
The circular arc steel sheet is semi-circular steel sheet, circular arc staple bolt is the semicircle staple bolt, can seal into the ring structure through 2 semi-circular steel sheets, and winding system in earlier stage and installation, the welding in later stage are all convenient, swift. The inner perimeter of the semicircular hoop is slightly shorter than the outer perimeter of the semicircular steel plate, and the two halves are butted when the bridge pier is installed, so that the bridge pier can be wrapped.
The lifting lugs 6 are fixedly arranged at the top of the circular arc-shaped hoop 1, so that the circular arc-shaped steel plate can be conveniently lifted in the later-stage installation process and the position of the circular arc-shaped steel plate can be fixed.
Two ends of each circular arc-shaped hoop 1 are fixedly provided with 1 connecting plate 4, and the bolts 3 penetrate through the adjacent 2 connecting plates 4 to fix the circular arc-shaped hoops 1 together to form a circular ring. Can realize convex staple bolt 1's high-speed joint, later stage is conveniently demolishd.
