Existing mensuration reinforcing steel bar machinery connects the method for residual deformation, generally adopts deformeter, arranges in the reinforcing bar symmetria bilateralis, gets the mean value calculation residual deformation value of reinforcing bar both sides meter reading.Because standard is when measuring, the clock gauge meter sense has strict requirement, therefore when measuring, can not have bigger rocking.
The utility model content
The purpose of the utility model is to provide a kind of Stability Analysis of Structures, easy to operate, inexpensive, can avoid the vibrations in the steel bar stretching process that the reinforcing steel bar machinery of the influence of test figure is connected the residual deformation measurement mechanism preferably.
For realizing above-mentioned purpose, the technical solution of the utility model is:
The utility model is that a kind of reinforcing steel bar machinery connects the residual deformation measurement mechanism, and it comprises upper bush, bar steel, clamping device, following quill, following fixed muffle and clock gauge; Described bar steel has two; Its top is fixed on the upper bush; Gap, its underpart is placed through in the through hole on the lower wing plate, and described clamping device is dismountable to be fixed on the middle part of bar steel and between upper bush and following quill, clock gauge is installed on the clamping device; The reinforcing bar that needs to measure passes successively and is fixed on upper bush, following quill, the following fixed muffle.
Described upper bush is made up of upper bush body and two upper flanges; On the sidewall of upper bush body, offer the reinforcing bar fixing threaded hole more than at least two; Two radially symmetrical both sides that are installed in the upper bush body of upper flange; On upper flange, offer and upper bush body mesopore through hole in the same way, on the sidewall of upper flange, offer the bar steel fixing threaded hole that connects the upper flange through hole; Described quill down is by quill body and two lower wing plates are formed down; On the sidewall of following quill body, offer at least more than one reinforcing bar fixing threaded hole; Two radially symmetrical both sides that are installed in down the quill body of lower wing plate are offered on lower wing plate and following quill body mesopore through hole in the same way; Offer the reinforcing bar fixing threaded hole more than at least two on the sidewall of described fixed muffle down; The top of described bar steel is placed through in the through hole on the upper flange and is screwed onto the screw retention in the upper flange bar steel fixing threaded hole, and the underclearance of bar steel is placed through in the through hole on the lower wing plate; The reinforcing bar of need measuring passes the upper bush body mesopore of upper bush, following quill body mesopore, the mesopore of fixed muffle down of quill down successively, and the upper bush body, quill body and following fixed muffle be respectively through radially being spirally connected screw retention on it on reinforcing bar down.
After adopting such scheme, because the utility model is when measuring, reinforcing bar makes that through upper bush, quill, the clamping of fixed muffle down down reinforcing bar is difficult for rocking, and has reduced the error of test, has the advantage of Stability Analysis of Structures, easy to operate, inexpensive.
Below in conjunction with accompanying drawing and specific embodiment the utility model is further described.
