A sliding structure in which the second one-sided sliding plate and the second one-sided connecting plate, which connects the one-sided mounting portion and the one-sided sliding damper connecting portion on the side of the second one-sided sliding plate, are superimposed.
- The sliding structure according to claim 1, wherein the one-side sliding damper connection portion has an overlapping portion in which the first one-side sliding plate, the first one-side joining plate, the second one-side sliding plate, and the second one-side joining plate are superimposed on the one-side sliding damper connection portion, and a non-overlapping portion in which the first one-side sliding plate and the second one-side sliding plate are superimposed, but the first one-side joining plate and the second one-side joining plate are not superimposed on the one-side sliding damper connection portion.
Description
This invention relates to a sliding structure. As a vibration damping mechanism for reducing vibrations in a building's frame, a pressure-contact sliding mechanism is known in which a first sliding plate belonging to one member, a sliding plate belonging to the other member, and a second sliding plate belonging to one member, which sandwiches the other sliding plate between the first sliding plate and the other sliding plate, are pressed against each other and slide (see, for example, Patent Document 1). Japanese Patent Publication No. 2021-162038 This is a conceptual diagram showing an example of the arrangement when a sliding structure is provided on the brace of a frame in one embodiment of the present invention.This is a conceptual diagram showing another example of the arrangement when the sliding structure shown in Figure 1 is installed on the brace of the frame.Figure 1 is an external view of the sliding structure.Figure 3 is an external view showing the sliding damper in the sliding structure as it is assembled at the factory.This is an external view of a sliding structure as a comparative example.Figure 5 is an external view showing the sliding damper in the sliding structure as it is assembled at the factory.This is an enlarged view of section A in Figure 3.This is an enlarged view of section B in Figure 5. The following describes embodiments of the present invention with reference to the drawings. As shown in Figure 1, in one embodiment of the present invention, the sliding structure 1 comprises one member 2, another member 3, and a sliding damper 4 provided between the one member 2 and the other member 3. In this embodiment, the sliding structure 1 is a vibration damping structure that dampens vibrations generated in the building's frame 5 during earthquakes, etc., and is provided on the brace 5a of the frame 5. One member 2 is a brace piece located on one side as viewed from the sliding damper 4, and the other member 3 is a brace piece located on the other side. One or both of the one member 2 and the other member 3 may be composed of multiple members divided in the longitudinal direction, and these multiple members may be connected at the site where the sliding damper 4 is installed. As an example, a conceptual diagram when the other member 3 is composed of multiple members is shown in Figure 2. The black circles in Figure 2 indicate the connection portion 5a1. Note that the sliding structure 1 is not limited to being provided on the brace 5a of the frame 5. As shown in Figure 3, the sliding damper 4 has a pressure-contact sliding mechanism 9 in which a first sliding plate 6 belonging to one member 2, a second sliding plate 7 belonging to the other member 3, and a second sliding plate 8 belonging to one member 2, which sandwiches the second sliding plate 7 vertically between the first sliding plate 6 and the second sliding plate 8, are pressed together vertically and slide horizontally. In this embodiment, for the sake of explanation, the direction in which the sliding damper 4 slides is referred to as the left-right direction, with one side being referred to as the left side and the other side as the right side. The direction in which the first sliding plate 6, the other sliding plate 7, and the second sliding plate 8 are pressed against each other is referred to as the up-down direction. The direction from the web side (described later) toward the other sliding plate 7 side is referred to as the up side, and the opposite side is referred to as the down side. The left-right direction and the up-down direction are perpendicular to each other. Furthermore, the direction perpendicular to both the left-right direction and the up-down direction is referred to as the front-back direction. The sliding damper 4 has a one-side sliding damper connection portion 10 connected to a one-side mounting portion 2a belonging to one member 2 on one side (left side), and provided with a first one-side sliding plate 6 and a second one-side sliding plate 8; and a other-side sliding damper connection portion 12 connected to a other-side mounting portion 3a belonging to the other member 3 on the other side (right side), and provided with a other-side sliding plate 7.
