Hereinafter, a sound insulation performance diagnosis apparatus according to an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is a schematic block diagram showing the configuration of a sound insulation performance diagnostic apparatus 10 according to an embodiment of the present invention.
The sound insulation performance diagnosis apparatus 10 includes an input unit 101, a storage unit 102, a sound insulation performance acquisition unit 103, a determination unit 104, and an output unit 105. The sound insulation performance diagnosis device 10 is, for example, a portable terminal device.
The input unit 101 inputs various information according to instructions from the user. The input unit 101 is, for example, a keyboard or a touch panel. The input unit 101 inputs floor material information representing a floor material before renovation (renovation) and floor material information representing a floor material after renovation.

The storage unit 102 stores sound insulation performance information in which flooring information and sound insulation performance are associated with each other.
The sound insulation performance acquisition unit 103 reads out the pre-reform sound insulation performance representing the sound insulation performance of the floor before renovation from the storage unit 102 based on the floor material information representing the floor material before renovation input from the input unit 101, and inputs Based on the floor material information representing the floor material after renovation input from the unit 101, the sound insulation performance after repair representing the sound insulation performance of the floor after renovation is read out.

FIG. 2 is a diagram illustrating an example of the sound insulation performance information stored in the storage unit 102.
The flooring information is information that represents the material constituting the floor. Here, for example, information indicating the slab thickness, the base configuration, and the material of the finishing material is stored as the flooring information. Moreover, the information showing slab thickness is memorize | stored for every thickness, such as 120 mm, 150 mm, 180 mm, for example. Information indicating the base configuration is stored for each type of base such as joist floor, direct pasting, double floor, sound insulation double floor, and the like. Information representing the material of the finishing material is stored for each material, such as composite flooring, solid flooring, cushion floor, tatami mat, thin tatami mat, carpet, and direct sound insulation flooring. In addition, as for the material of the finishing material, even when the same material is used, when there are a plurality of types of thicknesses, each thickness is stored for each thickness.

The sound insulation performance is stored in association with each piece of flooring information. The sound insulation performance is represented by, for example, an LL value (lightweight impact sound) and an LH value (heavy impact sound). The LL value is a value representing the sound insulation performance of the floor against a light floor impact, and the LH value is a value representing the sound insulation performance of the floor against a heavy floor impact. These values are based on the sound level measured / calculated by the measurement method specified in JIS A 1419-2. Those using a standard weight impact source are LH values, and those using a standard light impact source. Is expressed as an LL value. The LL value and the LH value are stored in association with each combination of the slab thickness, the base structure, and the finishing material.
By having the above-mentioned data structure, for example, the sound insulation performance of a floor constituted by a combination of composite flooring with a slab thickness of 120 mm, a foundation structure of joist floor, and a thickness A (mm) as a finishing material has an LL value of LL1a , It can be specified that the LH value is LH1a.
In this embodiment, the case where the LL value and the LH value are used as the sound insulation performance will be described. However, the sound insulation performance may be expressed not as the LL value or the LH value but as a frequency (Hz) and a sound intensity (dB). good.

FIG. 3 is a flowchart for explaining the operation of the sound insulation performance diagnosis apparatus 10. Here, as an example, it is assumed that a person in charge of the construction visits the owner carrying the sound insulation performance diagnosis apparatus 10 and consults about the specifications of the floor after the renovation before performing the renovation.
The person in charge grasps the construction state of the floor before the renovation based on the construction drawing of the property to be reformed or the result of the field survey. The input unit 101 inputs floor material information before renovation according to an input operation from a person in charge who has grasped the construction state (step S10). This input is performed, for example, by selecting a slab thickness, a base structure, and a finishing material from a pull-down menu in a column for selecting a floor material before reforming.

  Next, the person in charge asks the owner to select the finishing material for the floor after remodeling, and selects and inputs the selected finishing material from the pull-down menu. The input unit 101 inputs floor material information after remodeling according to an input operation representing the floor finishing material after remodeling input from the person in charge (step S11). This input is performed by, for example, selecting a slab thickness, a base configuration, and a finishing material from pull-down menus in a column for selecting a floor material after remodeling.

  When the floor material information before and after the renovation is input, the acquisition unit 103 refers to the sound insulation performance information stored in the storage unit 102 for the sound insulation performance corresponding to the input floor material information, and before the renovation. The sound insulation performance and the sound insulation performance after reforming are read out (step S12). The determination unit 104 compares the sound insulation performance before renovation obtained by the acquisition unit 103 with the sound insulation performance after renovation (step S13), and outputs a determination result corresponding to the comparison result to the output unit 105. For example, the determination unit 104 compares the LL value of the floor before remodeling with the LL value of the floor after remodeling, and when the LL values match, the information indicating that the sound insulation performance indicated by the LL value is the same. Is output (step S14), and when the LL value of the floor after remodeling is smaller than the LL value of the floor before reforming, information indicating that the sound insulation performance indicated by the LL value is improved (improved). Output (step S15). On the other hand, when the LL value of the floor after renovation is larger than the LL value of the floor before renovation, the determination unit 104 outputs information indicating that the sound insulation performance indicated by the LL value is not improved (step) S16). Here, the LL value represents that the smaller the numerical value, the better the sound insulation performance.

  Moreover, the determination part 104 determines similarly about LH value (step S17). That is, the determination unit 104 compares the LH value of the floor before remodeling with the LH value of the floor after remodeling, and when the LH values match, the information indicating that the sound insulation performance indicated by the LH value is the same. Is output (step S18), and when the LH value of the floor after the reform is smaller than the LH value of the floor before the reform, information indicating that the sound insulation performance indicated by the LH value is improved (improved). Output (step S19). On the other hand, when the LH value of the floor after renovation is larger than the LH value of the floor before renovation, the determination unit 104 outputs information indicating that the sound insulation performance is not improved (step S20). Here, the LH value indicates that the smaller the value, the better the sound insulation performance.

The output unit 105 displays a determination result representing the sound insulation performance on the touch panel based on the information obtained from the determination unit 104 (step S21). Here, information representing the sound insulation performance can also be output by voice.
The sound insulation performance acquisition unit 103 determines whether or not the floor material information of the floor after the renovation is input again (step S22). If the floor material information of the floor after the renovation is input again, the process proceeds to step S11. The process proceeds to accept input of floor material information of the floor after renovation, and the process proceeds to step S12. On the other hand, the sound insulation performance diagnosis apparatus 10 ends the process when the sound insulation performance acquisition unit 103 does not input again within a predetermined time or when an end instruction is input.
The person in charge can show the owner whether or not the sound insulation performance is improved by the reform by showing the screen of the sound insulation performance diagnostic device 10 to the client.
In this embodiment, both the LL value and the LH value are determined, but only one of the determinations may be performed.

FIG. 4 is a diagram illustrating an example of a screen output to the output unit 105. In the upper part of the screen, the floor information input for the floor before and after the renovation is displayed, and the LL value and the LH value acquired by the acquisition unit 103 are displayed in association with each other. In addition, the sound insulation performance determination result is displayed at the bottom of the screen. Here, a character string indicating that the LL value is improved and a character string whose LH value is improved are displayed side by side.
The owner can easily grasp whether or not the sound insulation performance is improved by the reform by referring to the information displayed in the determination result of the sound insulation performance.

  In the embodiment described above, the case where the acquisition unit 103 of the sound insulation performance diagnosis apparatus 10 acquires the sound insulation performance by referring to the sound insulation performance information stored in the storage unit 102 has been described. However, the storage unit 103 is provided in an external device (for example, a sound insulation performance calculation device), and the acquisition unit 103 communicates the floor material information input from the input unit 101 with the external device, thereby providing information on the sound insulation performance. May be obtained. In this case, the sound insulation performance diagnosis device 10 and the external device can communicate via a network such as the Internet. Further, the external device is further provided with a function corresponding to the determination unit 104, and the sound insulation performance diagnosis device 10 transmits the flooring information input from the input unit 101 to the external device, and the determination result obtained from the external device And the determination result may be output to the output unit 105.

  When inputting flooring information again, touch the flooring information displayed before and after renovation at the top of the screen shown in FIG. 4 via the touch panel to select from the pull-down menu. Then, the information may be input again, and the LL value and the LH value may be acquired and determined again according to the selected flooring information. In this manner, by inputting the floor material information after the renovation again, it is possible to grasp how the sound insulation performance is changed by a simple operation input. Also, according to the sound insulation performance judgment result, the floor material information is selected and input again, so that the floor material information is reviewed to meet the required sound insulation performance, and the floor material information that satisfies the target. Can be easy to find. Further, in a condominium or the like, the sound insulation performance of a floor is often defined by an LL value or an LH value. Therefore, by referring to the LL value and LH value after renovation displayed on the output unit 105 of the sound insulation performance diagnostic apparatus 10 described above, it is determined whether the sound insulation performance after renovation satisfies the sound insulation performance regulation in the apartment. Can also be done easily.

  In this way, by selecting and inputting the flooring material again, for example, it is possible to easily consider which of the finishing materials while grasping the sound insulation performance.

  In the above-described embodiment, the output unit 105 has described the case where both the result determined by the determination unit 104 and the sound insulation performance acquired by the acquisition unit 103 are output. The sound insulation performance acquired by the acquisition unit 103 may be displayed (for example, information at the upper part of the screen in FIG. 4 is displayed) without displaying the result. In this case, the person in charge or the owner can grasp whether or not the sound insulation performance is improved by comparing the values representing the sound insulation performance before and after the renovation.

  In the above-described embodiment, the sound insulation performance diagnosis apparatus 10 calculates a cost (material cost) required when renovation is performed according to the input floor material information when the floor material information is input. You may make it have. For example, a necessary material can be specified from the flooring information changed before and after the renovation, and the material cost can be calculated based on the unit price of the material and the area where the renovation is performed. In this case, the unit price of the material may be stored in the storage unit 102 and referred to. In addition, the area to be reformed may be input from the input unit 101 or may be obtained from design data to be reformed.

  In the above-described embodiment, the case where the owner selects the finishing material after renovation and inputs the selection result from the input unit 101 has been described. However, when flooring information before renovation is input, sound insulation is performed. The performance acquisition unit 103 reads the sound insulation performance information corresponding to the floor material information before the renovation, and stores the finishing material that is the same as or improves the sound insulation performance (performance that can reduce the noise level) in the storage unit 102. It may be specified by referring to and output by the output unit 105 as a candidate for a finishing material. As a result, the client can easily grasp which finishing material is used to maintain or improve the sound insulation performance. Here, the sound insulation performance acquisition unit 103 maintains or improves the sound insulation performance when the floor structure information that improves the sound insulation performance is specified not only in the finishing material but also in the renovation of the foundation structure. A combination of the base structure and the finishing material may be extracted and output by the output unit 105.

  The sound insulation performance diagnosis apparatus 10 in the above-described embodiment may be realized by a computer. In that case, a program for realizing this function may be recorded on a computer-readable recording medium, and the program recorded on this recording medium may be read into a computer system and executed. Here, the “computer system” includes an OS and hardware such as peripheral devices. The “computer-readable recording medium” refers to a storage device such as a flexible medium, a magneto-optical disk, a portable medium such as a ROM and a CD-ROM, and a hard disk incorporated in a computer system. Furthermore, the “computer-readable recording medium” dynamically holds a program for a short time like a communication line when transmitting a program via a network such as the Internet or a communication line such as a telephone line. In this case, a volatile memory inside a computer system serving as a server or a client in that case may be included and a program held for a certain period of time. Further, the program may be a program for realizing a part of the above-described functions, and may be a program capable of realizing the functions described above in combination with a program already recorded in a computer system. You may implement | achieve using programmable logic devices, such as FPGA (Field Programmable Gate Array).
