Embodiment
Below in conjunction with accompanying drawing the present invention is done to describe in detail.
Fig. 1, Fig. 2, Fig. 3 are respectively front view, vertical view and the left views that the present invention measures the simple instrument of construction engineering surface crack width.As seen from the figure, the present invention measures the simple instrument of construction engineering surface crack width, comprises top cover 1, reading dial 2 and the base 3 made with organic glass or other transparent material.
Fig. 4, Fig. 5, Fig. 6 are respectively front view, vertical view and the left views of top cover 1 among the present invention.As seen from the figure, described top cover 1 is the frame-like that three faces are formed, and the bottom of two side is provided with screw, and the both sides of its end face are provided with circular arc cutaway, and described end face is provided with the circular hole of inlaying magnifier.
Fig. 7, Fig. 8 are respectively the front view and the vertical views of reading dial 2 among the present invention.As seen from the figure, described reading dial 2 is that up big and down small ladder is cylindric.Paste the transparent film that has the equal difference scale mark at the lower surface of described reading dial 2, the width of described transparent film high scale line is provided with from 0.1mm～1.2mm equal difference, its etc. difference be 0.1mm.
Fig. 9, Figure 10 are respectively the front view and the vertical views of base 3 among the present invention.As seen from the figure, described base 3 is provided with the cuboid of a circular hole for the middle part, and the Si Jiaochu of described base is provided with screw.
The constituted mode that the present invention measures the simple instrument of construction engineering surface crack width is: earlier the middle part is provided with round-meshed rectangular base 3 and puts well, lower surface at the cylindric reading dial 2 of ladder pastes the transparent film that has scale mark again, the bottom that the described reading dial 2 and the circular hole of described base 3 are agreed with mutually penetrates in the described circular hole then, and make the height 1mm of its penetration depth less than described base 3, top cover 1 is installed at last, the setting of described top cover 1 can make the upper surface of its end face and the described reading dial 2 suitable distance of being separated by, two sides of described top cover 1 can be respectively be fixed as one by the Corner Strapped of screw 4 and described base 3 or the both sides by bonding mode and described base 3, in the radial position of the described transparent film high scale of the end face subtend line of described top cover 1 magnifier 5 are set.
The effect of described base 3 is to support described reading dial 2, and the transparent film that protection simultaneously is arranged on described reading dial 2 lower surfaces does not cause damage because of the surface friction with buildings.
The effect of described top cover 1 is fixing magnifier 5, and is connected as a single entity with described base 3 under the effect of screw 4.
Rotate described reading dial 2 when measuring for convenience, the present invention respectively is provided with a circular arc cutaway with the both sides of described top cover 1 end face, and is provided with 1 millimeter distance between the upper surface with described top cover 1 end face and described reading dial 2.
For easy accessibility, the present invention has adopted with screw 4 two sides of described top cover 1 and four jiaos of connected modes that fix of described base 3.
Smaller and more exquisite for the external form that makes instrument, to be convenient to carry, the magnifier 5 among the present invention has adopted the kind of shorter focal length, and the enlargement factor of selection magnifier 5 is 10～20 times.
Adopt the present invention to measure the simple instrument of construction engineering surface crack width, can estimate the fracture faces width with relative method and read.
When measuring the fracture width of construction engineering surface, described base 3 can be leaned against the surface of engineering cracks, and make directly over gauger's the eye distance instrument about 20 centimetres;
When the magnifier 5 that sees through described top cover 1 end face finds the crack, can adjust the direction of instrument, make the direction in described crack consistent with the direction of dotted line among Fig. 2;
Rotate described reading dial 2, and see through described magnifier 5, find scale the most close on the described transparent film, read the reading at this scale place, just can draw the fracture width of measured construction engineering surface with fracture width.
Such as, by contrast, find the 5th scale mark the most close with fracture width, then the fracture width of measured construction engineering surface is 5 * 0.1mm=0.5mm.
For another example, by contrast, find the 9th scale mark the most close with fracture width, then the fracture width of measured construction engineering surface is 9 * 0.1mm=0.9mm.
Below with embodiment the present invention is schematically described in conjunction with the accompanying drawings, this description does not have restricted, and shown in the accompanying drawing also is one embodiment of the present invention.So,, under the situation that does not break away from the invention aim,, all should belong to protection scope of the present invention without the creationary version of designing the surveying instrument similar to this technical scheme if those of ordinary skill in the art is enlightened by it.
