Plate connecting structure for prestressed concrete member tensioning mechanism

Abstract

The invention provides a plate connection structure used in the tensioning mechanism of prestressed concrete members, which includes a plate body provided with a plurality of through holes, the through holes run through the plate body and are distributed at even intervals along the end surface of the plate body; The bolts are in one-to-one correspondence with several through holes, the connecting bolts are inserted into the through holes, and the outwardly extending part passes through the through holes, inserted into the corresponding tension nuts, and fixedly connected with the tension nuts; the tension nuts are opposite to the plate body An abutting portion connected with the connecting bolt and suitable for abutting against the end surfaces of the tension nuts is interposed between the end surfaces of the tension nuts. The technical scheme makes use of the protruding abutting portion formed in the connection structure to sink the tension nut into the prestressed concrete component without being exposed during the forming process of the prestressed concrete component.

Description

technical field [0001] The invention relates to a plate used in a tensioning mechanism of a prestressed concrete member. Background technique [0002] At present, prestressed concrete components, such as pipe piles, square piles, T-shaped piles, etc., are important pile foundation materials, which are widely used in the foundation engineering of various buildings and structures, such as high-rise buildings, public buildings, general industrial , Civil buildings, ports, docks, highways, bridges and other fields. When pouring piles with concrete, it needs to go through a very important process, that is, the tensioning process. [0003] During tensioning, the fixed plate is usually used to anchor one end of the tension module, and the other end is stretched and displaced by the tension plate. It will cause the tensile module to tilt, that is, the steel rod or steel strand to bend, resulting in unqualified or failed tension, and affecting the quality of the pipe pile. In addi...

Problems solved by technology

[0004] However, the prestressed concrete members formed in the traditional tensioning technology scheme often have tension nut leakage, which causes the tension nuts to contact each other when the prestressed concrete members are docked, resulting in damage to the tension nuts, and even damage to the prestressed concrete members. end face damage
