Abstract
The utility model relates to a building engineering quality detecting meter, which comprises two parts: a guiding ruler and a plug ruler. The utility model is characterized in that the ruler body of 2-meter's long guiding ruler made of aluminium alloy sections is folded two sections; the folding position is provided with an alloy steel rotating shaft and a slip hook automatic locking device; a sensing device and a measuring circuit are arranged in the ruler body; the guiding ruler and the potentiometer type plug ruler have liquid crystal display. The utility model has the advantages that a suit of complete detecting meter is composed of two parts: the guiding rule and the plug ruler; a measuring sensor, a standard ruler body and the measuring circuit are integrated; the building engineering quality detecting meter has high resolution, visual display and strong functionality, and is suitable for supervising, detecting, checking and accepting the quality of the verticality, horizontality and surface evenness of building engineering.
Description
The utility model belongs to the measurement of vertical, the level in the surveying work, the detecting instrument of verticality, levelness and surface smoothness that particularly a kind of supervision, detection and examination that is used for construction engineering quality used.
At present, China in the detection to the verticality of buildings, horizontal flatness, surface smoothness, is to adopt lining rope, cable inlet bracket, line to weigh down and clearance gauge in the quality testing and checking and accepting of construction work basically.The appliance and the method that adopt, function singleness, measuring accuracy is low, technical obsolescence.Even mechanical pendulum hammer measuring instrument, because its scale resolution is thick, pointing accuracy is low, adopts range estimation to carry out the quality testing and the acceptance of work, exists the artificial collimation error bigger.
The purpose of this utility model is that employing infrared electro formula sensor is made senser element, is assembled in the same chi body, connect secondary instrument, realize that numeral shows, to improve the accuracy of detection and the resolution of construction engineering quality detecting instrument, realize the many usefulness of a chi, can carry out the detection of verticality and levelness; Simultaneously, be equipped with the digital display clearance gauge, make senser element, can carry out the detection of surface smoothness with potentiometric pick-up.
Construction engineering quality detector of the present utility model, form by guiding ruler and clearance gauge two parts, it is characterized in that, the blade of 2 meters long guiding rulers making by aluminium alloy extrusions be two sections collapsible, folding position is provided with alloy steel rotation axis and Slip Hook forced locking device, blade one side is for measuring measuring basis face and 3 gauge heads of degree of gravity vertical forwall surface and day water Pingdu, and the blade another side is measuring basis face and 2 additional gauge heads of surface measurements flatness, and blade inside is equipped with senser element and metering circuit;
The Slip Hook forced locking device of guiding ruler is made up of locking Slip Hook, button, return spring;
Senser element is mutual vertically arranged two pendulum infrared photoelectric sensors, each pendulum infrared photoelectric sensor is made up of infrared light supply, photoelectric cell, movable pendulum, the movable pendulum of horizon sensor and vertical reference is located on the same axle, two movable pendulums are respectively equipped with locking spring sheet and knob, are respectively equipped with infrared light supply and photoelectric cell in the both sides of each movable pendulum;
Metering circuit is made up of amplifier, analog to digital converter, LCD and power supply,
The potentiometer type clearance gauge is connected liquid crystal display watch and is formed by clearance gauge body, clearance gauge slip-on head.
Construction engineering quality detector of the present utility model, its using method is:
When measuring vertical degree, levelness: open blade, gauge head is pulled out, the location; Turn on the power switch, digital wash promptly has demonstration; Selector switch is threaded to level (or vertical) measuring position according to measuring needs, and according to current measuring state, the turn knob is locked unmeasured pendulum, and measuring pendulum is placed the measuring position, can measure.During measurement, the measurement face of gauge head is adjacent to tested surface, the turn knob, the light of infrared light supply emission is at this moment covered a part by pendulum, makes to shine photronic luminous flux minimizing, along with the difference of measured size, pendulum is also in corresponding change angle, the variation that then photronic light-receiving area is also corresponding with output signal, behind the value stabilization to be shown, reading of data, repeat 3 times, average, 180 ° of reversing blades are in same measuring position, duplicate measurements 3 times, average, again that two mean values are average, be the measured value of this tested surface; Measurement finishes, and with knob locking, closes power supply, and folding blade sets back gauge head.
The surface measurements flatness screws off the additional gauge head of 2 meters guiding rulers, this workplace of guiding ruler is attached tested surface set level, and measures gap between guiding ruler workplace and the tested surface with clearance gauge, and its maximal clearance is the value of surface smoothness, reads the digital display data.
Construction engineering quality detector of the present utility model, having advantage is, form the complete detector of a cover by guiding ruler and clearance gauge two parts, survey sensor, station meter body and metering circuit is integrated, can measure verticality, levelness and the surface smoothness of the buildings of different gauge length requirements simultaneously, resolution height, intuitive display, functional strong, adapt to wide.Be applicable to that building engineering quality supervision detects and checking and accepting, also can be used as underlying instrument and means that civil engineering works such as road, bridge, dam detect.
