Abstract
The invention discloses a method for measuring thickness of a floor by using a nondestructive thickness gauge. The nondestructive thickness gauge is adopted in the method. The method comprises the following steps of: 1, fixing a transmitting probe of the nondestructive thickness gauge on the lower surface of the floor, and drawing a point A at the position of the transmitting probe; 2, drawing three points, namely a point B, a point C and a point D at positions of the upper surface of the floor, which roughly correspond to the transmitting probe; measuring the lengths of a line segment BC, a line segment CD and a line segment BD, sequentially placing receiving probes on the point B, the point C and the point D, and respectively acquiring the lengths of a line segment AB, a line segment AC and a line segment AD through data values displayed by the nondestructive thickness gauge; and 3, calculating the distance between the point A and the plane of the triangle BCD, wherein the distance is the thickness of the floor; and thus obtaining the thickness value of the floor. By the method, the thickness of the floor can be quickly and accurately measured without positioning on a wall around measured points, so that the time is saved and the operation is simplified; and accurate thickness of the floor can be acquired by a few times of measurement, and data are acquired very quickly.
Description
Technical field
The present invention relates to the slab thickness field of measurement, especially for a kind of method of using the nondestructive thickness measuring appearance to measure slab thickness in the thickness measure of the floor between the space of not being connected.
Background technology
When using floor nondestructive thickness measuring appearance to measure slab thickness; For recording slab thickness accurately, must find the accurate position of transmitting probe through receiving transducer, because the transmitting probe of thicknessmeter and the both sides up and down that the receiving transducer branch is located at floor; Receive the obstruct of floor; Be difficult to the position of location transmitting probe, to lean on usually with orthogonal two sidewalls of floor be positioning reference, measure certain distance and confirm their position; With the line that guarantees transmitting probe and receiving transducer perpendicular to slab surfaces, thereby record the actual thickness of floor.Do like this take a lot of work, time-consuming, owing to possibly have deviation, can have influence on the authenticity of measurement result again as the position and the size of the wall of positioning reference itself.
Summary of the invention
Technical matters to be solved by this invention provides a kind of method of using the nondestructive thickness measuring appearance to measure slab thickness, can use the nondestructive thickness measuring appearance to measure the thickness of floor quickly and accurately.
For solving the problems of the technologies described above, the technical scheme that the present invention adopted is: a kind of method of using the nondestructive thickness measuring appearance to measure slab thickness, comprise the nondestructive thickness measuring appearance, and may further comprise the steps:
One, the transmitting probe of nondestructive thickness measuring appearance being fixed on the lower surface of floor, is an A with the position of transmitting probe;
Two, make 3 points at the floor upper surface with the roughly corresponding position of transmitting probe, promptly 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,, obtain the length of line segment AB, line segment AC and line segment AD respectively by nondestructive thickness measuring appearance data presented value;
Three. calculate and obtain the distance of some A to plane, triangle BCD place;
Through above-mentioned steps, obtain the one-tenth-value thickness 1/10 of concrete floor.
A kind of method of using the nondestructive thickness measuring appearance to measure slab thickness provided by the invention can be measured slab thickness rapidly and accurately, need not accurately to locate the position of accepting probe and transmitting probe, has saved the time, has simplified operation; Only depend on the measurement of less number of times, can obtain accurate slab thickness, it is very quick to obtain data.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is described further.
Fig. 1 is the layout synoptic diagram of transmitting probe and receiving transducer among the present invention.
Fig. 2 be the present invention when measuring the layout synoptic diagram.
Among the figure: transmitting probe 1, receiving transducer 2, support bar 3, ground 4, floor 5.
Embodiment
A kind of method of using the nondestructive thickness measuring appearance to measure slab thickness comprises the nondestructive thickness measuring appearance, may further comprise the steps:
One, as shown in fig. 1, the transmitting probe 1 of nondestructive thickness measuring appearance is fixed on the lower surface of floor 5, be an A with the position of transmitting probe 1;
Two, make 3 points at floor 5 upper surfaces with the roughly corresponding position of transmitting probe 1, promptly 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,, obtain the length of line segment AB, line segment AC and line segment AD respectively by nondestructive thickness measuring appearance data presented value;
Three. calculate and obtain the distance of some A to plane, triangle BCD place, this distance is slab thickness;
Through above-mentioned steps, obtain the one-tenth-value thickness 1/10 of concrete floor 5 rapidly and accurately.
Computing formula is following:
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 following:
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))
During use, with this computing formula input software for calculation, above-mentioned formula form is to meet the input form that computer software was suitable for; Microsoft Excel for example so only need be inserted the length data of line segment AB, line segment AC, line segment AD, line segment BC, line segment CD and line segment BD, can calculate slab thickness fast; Adopt the present invention to measure slab thickness, saved the time, simplified operation; Guarantee the accuracy of measurement result, improved work efficiency.
