Abstract
A spigot-and-socket large-cotter-diameter high-strength partially-prestressed concrete pole comprises an upper pole and a lower pole. The bottom end of the upper pole is connected with the top end of the lower pole through upper and lower end flanges and through bolts. The spigot-and-socket large-cotter-diameter high-strength partially-prestressed concrete pole is characterized in that a flange liner ring is welded on the inner side of the top end of the lower pole, one end of the flange liner ring extends out of the top end of the lower pole and is inserted into the bottom end of the upper pole, and the outer diameter of the flange liner ring matches with the inner diameter of the bottom end of the upper pole. Through the flange liner ring, the stress problem of a single bolt is solved well. Force of the bolt is largely decomposed by the flange liner ring, so that capabilities of bearing torsion and shear force are improved greatly for the flanged pole and structural mechanical property is improved. The spigot-and-socket large-cotter-diameter high-strength partially-prestressed concrete pole is safe to use, easy to manufacture and convenient to construct and popularize.
Description
Technical field
The utility model relates to the big tip of a kind of spigot-and-socket flange footpath high strength partially prestressed concrete electric pole.
Background technology
Present electric pole connection mainly contains steel plate circle welding manner and inside and outside flange connection, it all is to lean on 6-12 bolt on the flange to connect that general flange connects, easier, need not to employ electric welding machine, install than very fast, but this flange connects by bolt strained, particularly horizontal shearing force is bigger to the harm of bolt, when loosening, under the effect of wind-force, easily cause the loosening of bolt, influence the safe handling of electric pole.
Summary of the invention
The purpose of this utility model just provides the big tip of a kind of spigot-and-socket flange simple in structure, that use safety footpath high strength partially prestressed concrete electric pole.
The big tip of spigot-and-socket flange of the present utility model footpath high strength partially prestressed concrete electric pole, comprise electric pole, following electric pole, the top of the bottom of last electric pole and following electric pole is connected with bolt by flange end plate up and down, it is characterized in that, be welded with lining ring in the flange on the top medial surface of following electric pole, the top of electric pole and insertion were gone up in the bottom of electric pole under a distal process of lining ring went out in the flange, and external diameter and the last electric pole bottom internal diameter of lining ring are complementary in the flange.
The big tip of spigot-and-socket flange of the present utility model footpath high strength partially prestressed concrete electric pole, lining ring has solved single bolt strained situation preferably in the flange by adopting, the power that lining ring has decomposed most of bolt in the flange, make the flange electric pole bear torsion and shearing improves greatly, improved structural mechanical property, use safety, and be easy to make, be convenient to construction and promote.

The specific embodiment
The big tip of a kind of spigot-and-socket flange footpath high strength partially prestressed concrete electric pole, comprise electric pole 1, following electric pole 5, the bottom of last electric pole 1 is connected with lower flange end plate 3 usefulness bolts by upper flange end plate 2 with the top of following electric pole 5, it is characterized in that, be welded with lining ring 4 in the flange on the top medial surface of following electric pole 5, the top of electric pole 5 and insertion were gone up in the bottom of electric pole 1 under a distal process of lining ring 4 went out in the flange, and external diameter and the last electric pole 1 bottom internal diameter of lining ring 4 are complementary in the flange.
