Description
Technical field
The present invention relates to architecture construction field, specifically a kind of extendible deformation measurement chi.
Background technology
At present in construction, to different materials（Steel, wood, concrete etc.）Whether the component of making, when mounted, the deflection between measurement component meet standard requirement, use ruler and coordinate what clearance gauge was either completed with shorter deformation measurement instrument.The tool kind used in operation is more, and step is complicated, and reading is not accurate enough.
The content of the invention
It is an object of the present invention to provide one kind only can just complete goal task with a device and reading is accurate, measuring scale easy to operate.
In order to achieve the above object, the present invention is realized in：
A kind of extendible deformation measurement chi, it includes square steel tube, level leveling bubble, vertical levelling bubble, three scales, pointer, pointer chute, pointer lock, positive survey line rotating shaft, reverse survey line rotating shaft and two surveys line；The top surface of square steel tube is respectively equipped with level leveling bubble, vertical levelling bubble, and level leveling bubble, vertical levelling bubble are mutually perpendicular；Positive survey line rotating shaft and reverse survey line rotating shaft are vertically arranged in square steel tube, two surveys line are wound in two survey line rotating shafts respectively, and are stretched out from the same direction of rotating shaft, then surveying end face stretching from square steel tube two respectively；Three scales are arranged on the survey face of square steel tube one and the scale is generally aligned in the same plane inlinely in, on square steel tube wall pointer chute is provided with along length of the scale direction, the top of pointer chute is latched provided with pointer, and pointer realizes the movement and positioning of pointer in pointer chute and by being opened and closed pointer lock.
The application method of the extendible deformation measurement chi, including
Step 1, when tested rod member is bent outwardly, square steel tube is leaned against on tested rod member, positive survey line rotating shaft is rotated, survey line is released to component total length；By the horizontally or vertically levelling square steel tube of levelling bubble, pointer lock is unclamped, pointer is skidded off from pointer chute, behind top to tested rod member, screw pointer lock, the readout value from scale；
Step 2, when tested rod member curves inwardly, square steel tube is leaned against on tested rod member, positive survey line rotating shaft is rotated, survey line is released to component total length；By the horizontally or vertically levelling square steel tube of levelling bubble, pointer lock is unclamped, pointer is skidded off from pointer chute, behind top to tested rod member, screw pointer lock, the readout value from scale；
Step 3, the bending action for measuring using step 1 or step 2 methods described arc-shaped rod；
Step 4, be measured after, by rotating reverse survey line rotating shaft, withdraw survey line, you can terminate operation.
This measuring scale is that the action deformation detection to component can be achieved, and easy to operate, reading is accurate；At the same time it can also be synchronously completed under survey line cooperation and deformation detection is carried out to the bending action of whole arc component；It can need not so repeat, and then avoid cumulative measurement error.
Brief description of the drawings
Fig. 1 is the side view of this measuring scale.
Fig. 2 is the top view of this measuring scale.
