The measuring device for expansion joint has the benefits that the work efficiency is high and the measuring precision is high.
Description
Technical field
The present invention relates to field of measuring technique, be specifically related to a kind of expansion joint measuring appliance.
Background technology
Expansion joint prevents building member due to climate temperature change (heat expansion, shrinkage), makes structure produce crack or destruction and a build joint arranging along the suitable position in buildings or structures construction joint direction.Expansion joint be by basis more than building element be divided into two independent sectors as body of wall, floor, roof (except log cabin top), make buildings or structures can do horizontal extension along length direction.
The gap of the appropriate stroke of reasonable selection is very important, and the larger retractor device in gap more easily goes to pot.Adopt gap excessive or too small, and do not consider install time temperature and adjusting play.The measurement at whole expansion joint, current overhead road surface arranges secondary every year.Conveniently measure, generally to first, the expansion joint, road surface of Four-Lane Road measures.Could measure when this can only seal at night, due to problems such as light, visual angle and measurer precision during measurement, measuring has error, and data both instability are also unreliable.
In addition, the non-cutting time often locating to operate is greater than Measuring Time, and work efficiency is very low.
Further, once pinpoint the problems, the variable quantity at expansion joint, not in allowed band, must be set up the project immediately and keep in repair.Can set up the project maintenance can not run well for the moment, repair from pinpointing the problems to disease during this period of time in, overhead road surface is not intact, affects traffic.
Therefore prior art is urgently improved and is developed.
Summary of the invention
The technical problem to be solved in the present invention is to provide the expansion joint measuring appliance that a kind of work efficiency is high, measuring accuracy is high.
Technical solution of the present invention is:
A kind of expansion joint measuring appliance, comprise the measuring appliance body of expansion link with stiff end and built-in pointer, the side at described stiff end and expansion joint is fixed, described measuring appliance body is fixed on the opposite side at expansion joint, described pointer stage casing and parallel described measuring appliance body place plane hinged with described measuring appliance body; Described measuring appliance body both sides are provided with the through hole run through for described expansion link, and described expansion link is flexibly connected with described measuring appliance body, and described expansion link shaft and described pointer one end pivot joint.
Pointer is fixed in measuring appliance body and base plate hinged, its end and expansion link pivot joint, and when broadening owing to expanding with heat and contract with cold at expansion joint or narrow, pointer or offset the expansion status very clearly can determining expansion joint to the right, makes work efficiency increase left.
Described measuring appliance body comprises base plate and the housing suitable with base plate, and base plate is provided with expansion link live splint, and described expansion link passes through expansion link live splint.
Described expansion link live splint comprises the fixed part being positioned at two ends and the limiting section connecting two fixed parts, and this limiting section is provided with the stopper slot suitable with described expansion link.
Expansion link is limited in stopper slot by expansion link live splint, the expansion link being can only before and after after, thus drive needle deflection, improve measuring accuracy.
Described base plate and corresponding section, described pointer other end position are provided with curved scale graticule.
Described housing is provided with Transparent Parts in described graduated scale line position corresponding section.
Make staff very clearly can know the expansion status at this expansion joint at the extended variable at this expansion joint of observation, simple to operation.
Reinforcement is arranged with outside described pointer.
The mission life increasing pointer makes this measurement accuracy higher simultaneously.
Preferably, described expansion link is provided with warning part away from one end of described stiff end.
Beneficial effect of the present invention: work efficiency is high, measuring accuracy is high.
