Abstract

The invention relates to a steel twisted line tension measuring sensor that sets left end fixing cover on the left end of inner protecting canister, sets right fixing cover on the right end, sets inner gum ring between inner protecting canister and the right fixing cover. Left upper clipping wedge ring and left upper clipping wedge ring are set on the left end fixing cover. Right upper clipping wedge ring and right upper clipping wedge ring are set on the right end fixing cover. One end of the 2-8 even number spring tabs are set on the left end fixing cover and the other end is set on the right end fixing cover. Strain gauge is set on every spring tab. The strain gauge is connected by wire to form bridge circuit. The invention has reasonable design, simple structure, high accuracy, long useful file etc. It could be used to measure the tension of steel twisted line.

Description

technical field

[0001] The invention belongs to the technical field of force measurement, and in particular relates to a steel strand tension measurement sensor. technical background

[0002] Steel strand is made of high-quality carbon structural steel used in steel mills after cold processing, tempering and twisting. It has the advantages of good plasticity, no joints, convenient use, and high strength. It is currently widely used in various prestressed Concrete structure buildings, such as bridges, high-rise buildings, stadiums, industrial plants, mine storage and other buildings.

[0003] During the construction of prestressed concrete structures, most of the component concrete is poured first, and holes (or casings) are reserved in it. After the concrete reaches the required strength, multiple (up to 37) steel strands are placed. The wire is inserted into the reserved channel, supported by the jack at the end of the concrete member, and the steel strand is stretched, so...
