Including display and measuring probe.Connect display screen and measuring probe with cable during measurement, turn on the power switch, by measuring probe
Two legs be placed on crack, on a display screen it can be seen that be exaggerated crack pattern picture.Somewhat rotate photographic head and make crack pattern
As vertical with rule, according to graduation mark length shared by crack pattern picture, read fracture width value.Determine that special messenger periodically surveys with crack
Wide instrument and steel ruler measure width, the situation of change of length at observation station, and it is preferable and easy that this method is applicable to element surface quality
In the observation of the works fracture propagation of operation, need to carry New Instrument for Crack Width.And the maximum of current New Instrument for Crack Width the most on the market
Range is 8-10mm, for the wide seam of masonry structure, it is impossible to effectively measure.
(2) patch gypsum: the Gypsum Fibrosum powder slurry that modulation denseness is moderate, does the circle of thick layer about 3mm at crack to be measured
Or rectangle gypsum patty, make regular check on whether gypsum patty ftractures, determine the development in crack.This method is applicable to crack width
Spending less and operate the observation of works fracture propagation at inconvenience, there is certain error in measurement result.
(3) observation monument method is set: select at the maximum seam width of crack and crack end is as observation station, arrange observation mark
Will, periodically, determines people and measures the displacement of observation monument to quantitatively determine the extension of fracture width.This method is applicable to be easy to set
Putting observation monument and be easy to the position measured, observation monument to have the distinct end face or center being available for measuring.
In practical operation, use above-mentioned Crack Monitoring method not directly perceived, and the works crack periphery environment having be poor,
Use instrument and equipment monitoring more difficulty.
201110076395.X discloses a kind of engineering geologic fissure measuring method and measurement apparatus thereof, and this device includes two
The individual steel pipe pedestal being separately fixed at both sides, geologic body crack, two steel pipe supports are inserted also by the fixing termination of lower end respectively
Being fixed in the top steel pipe of described both sides steel pipe pedestal, the top of said two steel pipe support is connected to solid by pin
Location survey bar and mobile measuring staff, described fixing measuring staff and mobile measuring staff are attached by middle multi-functional geologic compass；Institute
Stating multi-functional geologic compass is cubic design, and fixing measuring staff is secured within portion, and its can with the pin of both sides measuring staff and
Rotatable washer is that support rotates freely.This case needs to arrange steel pipe pedestal, it is impossible to operate on concrete structure, and this case
Overall measuring process is relatively complicated.
Therefore, prior art still has necessity of improvement.
Summary of the invention

Being fixedly connected on described installing plate, described installing plate is provided with some screw holes, and the length of described axle sleeve is less than described installation
The length of plate, the external diameter of described rubber bush is consistent with the internal diameter of described axle sleeve, the internal diameter of described rubber bush and described pin
Diameter consistent, described rubber bush is integral type structure, and described rubber bush includes that sleeve body and baffle ring, described baffle ring set
Put the end in described sleeve body；
Two described pin hinge components are separately positioned on two ends, works crack, are fixed by self-tapping screw, described pin
Bolt inserts from the described pin hinge component of one end, passes from the pin hinge component of the other end.
In works Crack Monitoring device of the present utility model, the quantity of described screw hole is 4 ~ 6, described self tapping spiral shell
The quantity of silk is 16 ~ 24.
Implement this works Crack Monitoring device of the present utility model, have the advantages that this case is passed through across splitting
Seam and install graduated pin, the change of time recording scale, thus the change width in monitoring of structures thing crack；Pin inserts
In the rubber bush of pin hinge component, the frictional force being subject to is less, can slide in rubber bush flexibly, such that it is able to
Measure the change width in crack accurately；First hinge leaf and the second hinge leaf are serially connected by rubber bush, the first hinge
Chain page and the second hinge leaf can rotate around rubber bush, use more convenient；Apparatus structure is simple, measures the easiest,
Applied widely.
