Description
Technical field
The present invention relates to slab thickness fields of measurement, especially for a kind of method using nondestructive thickness measuring instrument to measure slab thickness in the thickness measure of the floor between space of not being connected.
Background technology
When using floor nondestructive thickness measuring instrument to measure slab thickness, for recording slab thickness accurately, the accurate location of transmitting probe must be found by receiving transducer, because the transmitting probe of thicknessmeter and receiving transducer divide the both sides being up and down located at floor, be subject to the obstruct of floor, be difficult to the position of localizing emission probe, usually orthogonal two sidewalls with floor will be leaned on to be positioning datum, measure certain distance to determine their position, to ensure that the line of transmitting probe and receiving transducer is perpendicular to slab surfaces, thus record the actual thickness of floor.Take a lot of work like this, time-consuming, again because the position of the wall as positioning datum itself and size may exist deviation, the authenticity of measurement result can be had influence on.
Summary of the invention
Technical matters to be solved by this invention is to provide a kind of method using nondestructive thickness measuring instrument to measure slab thickness, and nondestructive thickness measuring instrument can be used to measure the thickness of floor quickly and accurately.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is: a kind of method using nondestructive thickness measuring instrument to measure slab thickness, comprises nondestructive thickness measuring instrument, comprise the following steps:
One, the transmitting probe of nondestructive thickness measuring instrument is fixed on the lower surface of floor, with the position of transmitting probe for an A;
Two, make 3 points in the position that floor upper surface is roughly corresponding with transmitting probe, namely put B, some C and some D; Measure the length of line segment BC, line segment CD and line segment BD, receiving transducer is successively placed on a B, some C and some D, the data value shown by nondestructive thickness measuring instrument, obtains the length of line segment AB, line segment AC and line segment AD respectively;
Three. calculate the distance obtaining some A to triangle BCD place plane;
If: the length of line segment BC, line segment CD and line segment BD is respectively a, b and c, and the length of line segment AB, line segment AC and line segment AD is respectively d, e and f, and slab thickness is H, and so, the computing formula of slab thickness is as follows:
H=sqrt(4×f^2×e^2×d^2-f^2×(e^2+d^2-a^2)^2-e^2×(d^2+f^2-c^2)^2-d^2×(f^2+e^2-b^2)^2+(f^2+e^2-b^2)×(e^2+d^2-a^2)×(d^2+f^2-c^2))/4/sqrt((a+b+c)/2×((a+b+c)/2-a)×((a+b+c)/2-b)×((a+b+c)/2-c))
By above-mentioned steps, obtain the one-tenth-value thickness 1/10 of concrete floor.
