Description

  The present invention relates to a seismic structure experience device for transmitting the principle of a seismic structure used in a building to customers and the like.

  Buildings built in Japan have earthquake-resistant structures in consideration of the frequent occurrence of earthquakes in the Japanese climate. As such an earthquake-resistant structure, the following has been devised.

  For example, as shown in FIG. 15, a brace structure 201 provided with a brace 104 that diagonally connects the apexes of a frame 103 in which a vertical line 101 and a horizontal line 102 are connected in a substantially rectangular shape to a building H, for example, 16, a panel structure 202 in which a panel 108 is attached so as to cover a frame 107 in which a pillar 105 and a beam 106 are joined to a building H in a substantially rectangular shape, as shown in FIG. 16, or as shown in FIG. 17, There is a rigid frame structure 203 in which a column 108 and a beam 109 are rigidly joined to the building H with a torcia type high tension bolt or the like so that the column 108 and the beam 109 are substantially integrated.

  However, after the construction of the building is completed, the structure as described above is inside the wall of the building and cannot be visually confirmed. However, for the customers who purchase the building, the earthquake-resistant structure explains the principles of the earthquake-resistant structure, such as how the shaking exerts a force on each member during the earthquake and suppresses them. There are many opportunities to do. In addition, it is necessary to make the principle of the earthquake resistant structure known to the new employees of the company that sells the design of the earthquake resistant structure and the building equipped with the earthquake resistant structure in order to perform business. However, it is difficult to easily understand the principles of these seismic structures simply with drawings, illustrations, or simple explanations. Therefore, it is a device for explaining the energy absorption action of the seismic structure, and as shown in FIG. 18, both end portions of the vertical member 301 and the horizontal member 302 are rotatably fixed by the pins 303, and at the same time by the pins 303. An oblique member 304 that can be bent and deformed has been devised by deforming the model 305 by applying a force in the direction of an arrow 306 to the model 305 fixed in a diagonally rotatable manner (for example, Patent Documents). 1).

  However, when explaining the brace structure using the model as described above, only a part of the structure related to the earthquake-resistant structure can be explained, and comparison with other earthquake-resistant structures should be made. I can't. Furthermore, it has been difficult to systematically explain and understand the principles of the earthquake-resistant structure as described above.

  The present invention has been made for the purpose of solving the various problems as described above, and does not require a large-scale experiment or device. The present invention relates to a seismic structure experience device that allows customers and others to understand these principles and how force acts in the event of an earthquake by touching and deforming directly.

In order to achieve the above object, an earthquake resistant structure experience device according to claim 1 is an earthquake resistant structure experience device for explaining the principle of an earthquake resistant structure used in a building, and both end portions of four bar members are provided. A substantially rectangular frame member that is rotatably connected and fixed to each other, two braces whose opposite ends are rotatably connected to the apex of the frame member in a diagonal manner, and provided on each of the braces And a brace structure model having an adjustment member that allows the brace to be extended and contracted, and a panel member that is long in the width direction and whose both ends are rotatably fixed to the frame member. A panel structure model arranged in parallel in the vertical direction, and a substantially rectangular frame structure model in which both ends of four elastic rod members having elasticity are connected to each other via a connection member , The back is each It is supported by the support plate via the guide member for guiding the forming model in the width direction, and the vertical direction is characterized in Rukoto.

The seismic structure experience device according to claim 2 is the seismic structure experience device according to claim 1, and is arranged in parallel in the height direction with a predetermined interval in the width direction on the outer surface of the panel member of the panel structure model. A reference line extends across each panel member in a substantially vertical direction.

Seismic structure experience apparatus according to claim 3, in seismic construction experience apparatus according to claim 1 or 2, wherein the regulation member of the brace model, that projections for viewing stretching length of the brace is provided It is a feature.

According to the seismic structure experience device according to claim 1, since the structural model relating to the brace structure, the panel structure, and the ramen structure, which is representative of the seismic structure, is provided, each structural model is directly touched and deformed. Therefore, it is possible to make customers understand systematically these principles and how the force acts in the event of an earthquake. Further, by comparing each structure, it is possible to know each difference more clearly and deepen the understanding of each structure. Furthermore, according to the seismic structure experience device, the back surface of each structural model is supported by the support plate via the guide member that guides the structural model in the width direction and the vertical direction.
