Abstract
The utility model relates to a concrete carbonization depth admeasuring apparatus, belonging to an apparatus which is used for testing the depth of concrete carbonization in the technical field of the non-destructive test of concrete. Because the apparatus can indicate the amplified depth value of the concrete carbonization of the apparatus through a lever principle, compared with the existing test with straightedges, the utility model has the advantages of easy test, accuracy, etc.; the utility model is particularly suitable for the inspection techniques of 'concrete compression strength is evaluated through a rebound method ' and ' the concrete compression strength is synthesis through a rebound ultrasonic synthesis method'.
Description
The invention belongs to the instrument of the Measuring Object hole wall degree of depth, be used for concrete non-destructive test technical field and measure the carbonization of concrete depth value.
Regulation in " Ministry of Urban and Rural Construction and Environmental Protection of People's Republic of China (PRC) ministerial standard " rebound method evaluation concrete crushing strength technical regulation " JGJ23-85 " the 332nd: " when measuring the carbonation depth value; available proper tools; surveying the hole (its degree of depth is slightly larger than the carbonization of concrete degree of depth) that the surface, district forms the about 15mm of diameter; remove powder and chip (not handy liquid wash) in the hole then; and be the edge that 1% phenolphthalein alcoholic solution is sprinkled upon the hole inwall with concentration immediately; again with the steel ruler measurement from concrete surface the vertical range to the representative intersection of deep nondiscolouring (carbonization does not partly become aubergine) 1-2 time; this distance is the carbonization of concrete depth value, and each the survey read to 0.5mm." because no suitable measurer, therefore regulation adopts steel ruler to measure.This measuring method is the reading difficulty not only, and readability standard not, does not satisfy measuring accuracy.
The objective of the invention is to develop a kind of energy easy, measure the instrument of concrete carbonization depth exactly.
Main body of the present invention is made up of casing and movement two parts, is described in detail as follows:
Instrument is analysed and observe as shown in the figure, casing is made up of housing (12) and chi cover (9), movement by side plate (11) and side plate (6) with contact pilotage (1), base (2), pointer (8), pull out wheel (13), rule (10) etc. and fuse, and fix by screw and casing.
Contact pilotage (1) is connected by fork (3) with pointer (8), and elongates or shortens by adjusting screw (14).After contact pilotage (1) touches a certain degree of depth of object hole, can on rule (10), illustrate by the lever amplification of fork (3), pointer (8), fork (3) is fixed on the movement by bearing pin (15) and axle sleeve (5), and the torsion spring (4) on the axle sleeve (5) is guaranteed the swing of fork (3) and resetted.
In movement, the other end that pulls out wheel (13) connects a cam, is used to regulate the angle of contact pilotage (1), so that contact pilotage (1) touches a certain degree of depth of the object hole that needs measurement, and pins measured value by stage clip (7).
The base (2) of this measuring instrument is placed concrete surface, contact pilotage (1) stretches into (about 15 millimeters of hole diameter in the concrete hole, about 10 millimeters of the degree of depth), make its interior edge of touching concrete carbonization thickness with pulling out wheel (3) adjustment contact pilotage (1), the concrete carbonization depth value through amplifying can be shown on rule (10).
It is simple that the present invention has manufacturing process, easy to operate, and measured value amplifies to survey through a lever to be read to 0.25 millimeter, easier, accurate than the steel ruler measurement, is used for the mensuration precision that " concrete non-destructive test technology " can improve the concrete crushing strength value.
Claims (5)
1, the instrument of the Measuring Object hole wall degree of depth, this instrument shape such as capsule, long 5 centimetres, wide 3 centimetres, high 10 centimetres (high-end), the one end has the contact pilotage (1) that touches into the hole wall, the other end is rule (10), it is characterized in that touching into the degree of depth of contact pilotage (1) regulated by thumb wheel (13), contact pilotage (1) connects fork (3) and also is fixed on bearing pin (15) and goes up and form balance pivot, and the other end of fork (3) connects indication and touches pointer (8) into the degree of depth.
2, instrument according to claim 1 is characterized in that with bearing pin (15) being that the formed lever of fulcrum is a curved arm lever.
