Description of the Related Art In general, heavy floor impact sound measurement is used to examine the acoustic characteristics of a building. FIG. 6 shows a model of the heavy floor impact sound measurement. In FIG. 6, reference numeral 100 denotes a building, and 101 denotes a floor separating the building 100 into a first floor and a second floor. The floor 101 also includes a lower floor ceiling 101a. On the second floor, a heavy floor impact sound generator 110 is installed, and on the first floor, a sound level meter 130 including a microphone 120 is installed. As shown in FIG. 7, a heavy floor impact sound generator 110 has a rubber tire 114 attached to a tip end of an arm 113 rotatably attached to a base 111 by a shaft 112, and the arm 113 is rotated and displaced. Let me tire 1
14 is positioned at a predetermined height and then dropped in the direction indicated by arrow a to give an impact force to the floor 101 to generate an impact sound. [0004] The impact force given by the heavy floor impact sound generator 110 is, for example, shown in FIG.
It is defined as shown below. In FIG. 8, a range surrounded by the curves (a) and (b) is an allowable range of the first impact force characteristic. Here, the curve (a) shows a formula representing the upper limit of the first allowable range, Y1max (t) = 4.2 sin ((t + 2) · π / 24), and the curve (b) shows the first allowable range. Expression representing the lower limit of Y1mi
n (t) = 3.6 sin (t · π / 20). The range enclosed by the curves (c) and (d) is the allowable range of the second impact force characteristic. Here, the curve (c) shows a formula representing the upper limit of the second allowable range, Y2max (t) = 2.1 sin ((t + 2) · π / 24), and the curve (b) shows the second allowable range. An expression representing the lower limit of Y2min (t) =
Indicates 1.8 sin (t · π / 20). [0005] Heavy floor impact sound generator 1
The impact force that the floor 10 gives to the floor is mainly the rubber tire 11
4 is determined by the height of the rubber tire 114 and the air pressure of the rubber tire 114. The air pressure of the rubber tire 114 often fluctuates in a long term, and also fluctuates depending on the temperature. When the air pressure fluctuates, the impact force applied to the floor 101 also fluctuates. Therefore, the reliability of whether or not the impact force characteristic generated by the heavy floor impact sound generator 110 is within the allowable range shown in FIG. 8 is not so high. Did not. The present invention has been made in view of the above-mentioned problems of the prior art, and an object thereof is to provide an impact force capable of easily measuring the impact force of a heavy floor impact sound measuring instrument or the like. It is intended to provide a measuring device. [0007] In order to solve the above problems, the present invention provides a force detecting means for detecting an impact force of a falling object, and a signal processing for processing an output of the force detecting means.

And an imaginary circle Vc having a radius smaller than the radius of the impact receiving member 2. Therefore, when the rubber tire 114 of the heavy floor impact sound measuring device falls on the upper surface of the impact receiving member 2, the impact force applied to the impact receiving member 2 is detected by these three load sensors 2a, 2b, 2c. As shown in FIG. 3, the measuring device main body 3

As shown in FIG. 4, a signal processing unit 20 is built in the measuring device main unit 3. Signal processing unit 20
Is a charge amplifier 6, an A / D converter 7, a CPU 8, a RAM
9 and ROM 10. In the signal processing unit 20,
The outputs of the three load sensors 2a, 2b, 2c are combined and then input to the charge amplifier 6. The output of the charge amplifier 6 is converted by an A / D converter 7 from an analog quantity to a digital quantity. The output of the A / D converter 7 is input to the CPU 8. The ROM 10 stores time-series data of an upper limit (Y1max (t)) and a lower limit (Y1min (t)) for displaying an allowable range of the first impact force characteristic based on the recommended measurement standards of the Architectural Institute of Japan. The upper limit (Y2max (t)) and the lower limit (Y2min (t)) time series data for displaying the allowable range of the second impact force characteristic are stored. The CPU 8 sorts the input values in time series, displays them on the liquid crystal display section 4b,

The character string “NG” is displayed. The operation of the thus configured impact measuring device according to the present invention will be described. First, the measurement mode switch Sw1 is turned on to put the entire impact force measurement device in a state of waiting for input, and furthermore, the allowable range changeover switch Sw
5 is operated to select which of the allowable range of the first impact force characteristic and the allowable range of the second impact force characteristic is to be displayed. Next, the rubber tire of the heavy floor impact sound generator is dropped on the upper surface of the impact receiving member 2 of the force detector 1. At this time, time series data corresponding to the digitized impact force of the combined output of the three force sensors is input to the CPU 8. The CPU 8 captures the time-series data, displays the data on the liquid crystal display unit 3d, and sets the allowable range switch S
The allowable range of the impact force selected by the operation of w5 is also displayed on the liquid crystal display unit 3d. At the same time, if the input value is within the allowable range, a character string "OK" is displayed, and if not, a character string "NG" is displayed. This is shown in FIG. However, FIG. 5 shows an example in which the first allowable range is selected, and further, an example in which the impact force falls within the allowable range. Thereafter, if necessary, the store switch Sw
Then, the time series data corresponding to the impact force obtained by operating 2 is stored in the RAM 9. Further, if necessary, the print switch Sw4 is operated to output the display screen of the liquid crystal display unit 3d to a printer (not shown). As described above, this impact force measuring device is a force detection unit 1 for detecting a drop impact force of a rubber tire of a heavy floor impact sound generator and the output of the force detection unit 1 is displayed in a time-series graph.

When the time series data of the floor impact force is displayed, a graph showing the allowable range of the impact force determined by the Architectural Institute of Japan recommended measurement standard is also displayed. You can check at a glance whether it is in or not. Further, when the time series data of the floor impact force is displayed together with the graph indicating the allowable range of the impact force determined by the measurement standards recommended by the Architectural Institute of Japan, the time series data of the floor impact force is set to a predetermined floor impact force. When it is within the allowable range of force, it is displayed as a character string "OK", and when it is not, it is displayed as a character string "NG", so just look at this character string It can be determined at a glance whether or not it is within the allowable range. In the above-described embodiment, when the graph indicating the allowable range of the impact force determined by the Architectural Institute of Japan recommended measurement standard is displayed, the graph is electrically drawn on the liquid crystal display unit 4b. Alternatively, the display may be fixed on the front surface of the liquid crystal display unit 4b with paint. Further, in the above-described embodiment, the automobile tire 13 is used as the elastic member to be dropped. However, the point is that it is only necessary to apply an impact force that falls within the allowable range of the impact force determined by the Architectural Institute of Japan recommended measurement standard, so that falling objects other than tires may be used. Further, in the above-described embodiment, the case where the impact force measuring apparatus of the present invention is applied to the calibration of a gravity force floor impact sound generator has been described. However, the object to be measured may be any other object as long as it gives an impact force. In this case, the allowable range is set arbitrarily according to what gives the impact force. As described above, according to the present invention, there is provided a force detecting means for detecting the impact force of a falling object, and a signal processing means for processing the output of the force detecting means. Can be easily measured. [0030]
