Description

{The impact sound generating device for the measurement of floor impact sound insulation}

The present invention relates to an impact sound generating device for measuring the floor impact sound blocking performance, and is easy to manufacture, operate and move due to a simple structure, and to accurately measure the floor impact sound due to the accuracy of the drop height and the consistency of the drop intervals. The present invention relates to an impact sound generating device for floor impact sound isolation performance measurement that can maximize labor efficiency while reducing labor.

Apartment houses such as apartments or townhouses, which are typical types of modern dwellings, share the floors and floors of neighbors with noise, children running, footprints, and knocks. The noise generated by neighboring households is called the floor impact sound.

The floor impact sound is classified into light impact sound and heavy impact sound according to the characteristics of the noise, and the light impact sound is an evaluation index indicating the degree of noise in the floor directly below by the impact on the floor when a small object falls or the furniture is moved. This is measured using a standard tapping machine.

In addition, the weight shock sound is an evaluation index indicating the degree of noise in the floor immediately below the heavy impact generated when the child runs or runs, and it is measured by using a standard shock machine (Bang Machine).

As a device for measuring the weight impact sound, a heavy sound generator hitting at a predetermined interval by a tire or a weight body has been developed and used.

As shown in Figures 1a and 1b to solve the conventional problems, the floor shock sound generator has been proposed as the Republic of Korea Registration No. 20-0370830.

The conventional floor impact sound generator includes a pedestal (1) formed with a partition wall (1b) having a control unit (1a) on the side of the body, the storage space is formed inside the drive motor (1c); The drive shaft 2 and the drive shaft, which are installed on the pedestal 1b, are provided with a pulley 2a at the center of the body, and are driven by the power of the drive motor 1c fixed to one side of the pedestal 1. The tire 4b is fixed at the end of the support 4a having a predetermined length above the main body 3, which is supported by (2), and the other end is fixed to the main body 3 and the striking member 4 and the main body. (3) is fixed on the inside of the sub-axis (5) and the partition (1b), which is fixed to the axial axis, the friction link (5a) and the release ring (5b), the spring (not shown) in contact with the pulley (2a), A guide shaft having a drive shaft 2 located therein and having a fixed support 6 on which one end of the sub chain 6a is fixed, and a weight body 7a fixed on the other end of the sub chain 6a. 7b is axially connected to the main body 3, and a guide roller (not shown) for rotating the release ring 5b by the rotation of the guide shaft 7b is connected to the link member 7c. It consists of the release means 7 which is connected and fixed with the guide shaft 7b.

In the conventional floor impact sound generator, when the power generated from the drive motor 1c rotates the drive shaft 2 through the drive chain 1d, the sub-axis (by the friction link 5a in contact with the pulley 2a) 5) is fixed, and the sub-axis 5 and the fixed body main body 3 is rotated together to lift up.

At this time, the release ring 5b fixed to the sub-axis 5 also rotates together with the main body 3, and simultaneously pushes the guide roller located at the bottom of the release ring 5b backward, thereby releasing the guide roller. The means 7 are also rotated simultaneously with the main body 3.

In addition, the return spring is connected to one end of the guide roller and one end of the release ring 5b so that the mutual operation can be performed more smoothly.

In the process of retracting the guide roller by the rotation of the main body 3, when the friction link 5a in contact with the pulley 2a reaches a top dead center, the pulley 2a cannot push the release ring 5b any further. It will not retract the guide roller.

In addition, the weight body 7a integrally formed with the guide roller rotates together when the main body 3 rotates. When the body body 3 rotates a certain distance, the weight body 7a is formed by the sub chain 6a bound to the fixed support 4a. Rotates backward by weight.

That is, if the sub chain 6a connected to the fixed support 4a and the weight body 7a does not have a margin in the length when the weight body 7a is positioned in the vertical direction by using the length, 6a grabs the weight 7a and naturally rotates only the weight 7a to the rear side.

Then, while the striking member 4 strikes the bottom surface, the friction link 5a comes into contact with the pulley 2a again, thereby transmitting power of the drive shaft 2 to the sub shaft 5 again.

That is, after the striking member 4 hits the bottom surface, the friction link of the sub shaft 5 again comes into contact with the pulley 21 of the driving shaft 20, and thus the sub shaft 50 is fixed to the main body 30. Will be lifted.

In this way, by the rotation of the drive shaft (2) and the binding and release of the sub-shaft (5), the striking member (4) of the main body 30 to perform a repetitive operation, the sub-axis (5) is a weight ( As 7a) is moved, the sub-axis 5 is bound and released.
