SOLUTION: This display is arranged, side by side, with a first display section (1) indicating the condition of the quake when a building not installed with the TMD receives traffic vibrations etc., and a second display section (2) indicating the condition of the quake when a building installed with the TMD receives the traffic vibrations, etc. Model figures (3) and (6) indicating the quake width of a three-storied house and graphs (4) and (7) indicating the degrees of the quake of the three-storied house with lapse of time are respectively displayed in the first and second display sections (1) and (2).

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a TMD (Tuned Mass) for reducing the shaking of a building due to traffic vibration and the like.
The present invention relates to a display object for explaining the shake reduction effect of Damper).

[0002]

2. Description of the Related Art When a three-story house is constructed adjacent to a vibration source such as a road, a route, or a factory with heavy traffic, uncomfortable shaking due to traffic vibration or the like is likely to occur. This is because the frequencies of the building and the ground are more likely to resonate than in a two-story house, and the frequencies are slow vibrations that are easily felt by humans.

Therefore, in order to suppress the shaking of such a three-story house, an attempt has been made to install a TMD including a weight, a spring, an attenuator and the like. This kind of TMD
Has a function of canceling the vibration by the inertial force of the weight acting in the opposite phase to the shake, and can suppress the shake to the extent that it does not interfere with daily life.

[0004]

However, in the prior art, there are few tools for explaining such a TMD swing reduction effect in a visually easy-to-understand manner.
When adopting D, it was not possible to deepen the understanding of users and new buyers of homes.

In view of this, the present invention solves the above problems and makes it possible to visually understand the TMD shaking reduction effect in an easy-to-understand manner, and to deepen the user's understanding of TMD and a new purchaser of a home. The purpose is to provide goods.

[0006]

In order to solve the above-mentioned problems, the display object of the present invention comprises a first display section showing a shaking condition when a building not equipped with TMD receives traffic vibration or the like. , The second display section showing the state of shaking when the building in which the TMD is installed receives traffic vibration or the like is arranged side by side.

Further, the first and second display portions respectively display a schematic diagram showing the swing width of a three-story house and a graph showing the degree of swing of the three-story house over time. Further, the sensation level is displayed on the graph showing the degree of shaking of the building.

[0008]

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 shows a display object for explaining the TMD swing reduction effect according to an embodiment of the present invention. In this display, the first display part (1) showing the shaking condition when a three-story house without TMD is subjected to traffic vibration, and the three-story house with TMD installed The second display portion (2) showing the condition of the shaking when receiving the data is arranged side by side.

[0009] The first display (1) is a schematic diagram (3) showing the swing width of a three-story house without a TMD installed, and the degree of shaking of a three-story house without a TMD installed over time. The graphs (4) shown schematically are displayed side by side.

In the schematic diagram (3), the shaking width is represented by superimposing the three-story house shown by the solid line in the unswayed state and the three-story house shown by the dotted line in the horizontal direction. I am trying.

Graph (4) is a line graph in which the vertical axis represents vibration level and the horizontal axis represents time. In this graph (4), the level of the sway felt by the body, that is, the sensation level (the sensation range boundary) is displayed. This sensation level is specifically a 55 dB level.

The first display section (1) also displays an explanatory note (5) showing the shaking condition of the three-story house above the graph (4). Specifically, a display such as "I sometimes feel shaking on the third floor" is displayed.

A TMD is installed on the second display section (2).
A schematic diagram (6) showing the swing width of a one-story house and a graph (7) showing the degree of shaking of a three-story house with TMD installed over time are displayed side by side.

In the schematic diagram (6), the shaking width is expressed by superimposing the three-story house shown by the solid line in the unswayed state and the three-story house shown by the dotted line in the horizontal direction. I am trying.

Graph (7) is a line graph in which the vertical axis represents vibration level and the horizontal axis represents time. And this graph
In (7), the level of sway felt by the body, that is, the sensation level
(Boundary of sensation area) is displayed. This sensation level is specifically a 55 dB level.

In the second display section (2), an explanatory note (8) showing the shaking condition of the three-story house is displayed above the graph (4). Specifically, a display such as “reduce shaking on the third floor” is displayed.

Comparing the first display section (1) and the second display section (2), it is clear that the swing width and the degree of swing of the house are smaller when the TMD is installed. It can be seen that the shaking is reduced. Therefore, by referring to this display object, it is possible to visually understand the TMD swing reduction effect in an easily understandable manner.

The present invention is not limited to the above embodiment, and it goes without saying that many modifications and changes can be made to the above embodiment within the scope of the present invention.

[0019]

As is apparent from the above description, in the display object of the present invention, the situation in which a building without TMD is subjected to traffic vibration or the like, and the building with TMD is subjected to traffic vibration. Since it is possible to compare the shaking conditions when receiving such information, it is possible to understand the shaking reduction effect of TMD easily at a glance and easily understand it, and to deepen the understanding of users and new purchasers of homes about TMD. be able to.
