Double-end mechanical expansion type connecting assembly

Abstract

The invention provides a double-end mechanical expansion type connecting assembly. The double-end mechanical expansion type connecting assembly comprises a double-end mechanical expansion type inserting rod, wherein the double-end mechanical expansion type inserting rod comprises a rod body and two mechanical expansion type nuts, and expansion heads are arranged at the upper end and the lower endof the rod body; and the two mechanical expansion type nuts are correspondingly connected with two expansion head buckles. The double-end mechanical expansion type connecting assembly can be used forconnecting two precast piles (prestressed concrete piles), the two mechanical expansion type nuts are correspondingly and fixedly connected with the two precast piles (such as being fixedly connectedto one ends of the two precast piles), and then the two mechanical expansion type nuts are correspondingly connected with the two expansion head buckles to connect the two precast piles. According tothe double-end mechanical expansion type connecting assembly, through the mechanical buckle connection, compared with current end plate electrowelding welding, the welding process is simple, the double-end mechanical expansion type connecting assembly is difficult to be affected by the welding level of welding personnel, and the problem that welding is inconvenient on some occasions by adopting anelectrowelding welding mode (such as the occasion where electric welding machines and connecting power lines are inconvenient to use) can be solved.

Description

technical field [0001] The invention relates to the technical field of mechanical connectors, in particular to a double-head mechanical expansion connector assembly. Background technique [0002] Prestressed concrete piles have the advantages of high vertical bearing capacity of a single pile, factory production, fast construction speed, and reliable quality. They have been widely used in many fields such as industrial and civil buildings, railway terminals, etc., and become one of the most widely used pile types in my country. . The connection between traditional prestressed concrete piles usually adopts the form of end plate (such as steel plate) welding to connect piles with piles. Because this connection method belongs to electric welding, the welding process is complicated, and it is easily affected by the welding level of the welder, and it is inconvenient to weld in some occasions (such as inconvenient to use an electric welding machine and connect a power line).
