DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for connecting a cover panel structure of an expansion joint device for closing a gap between frames of adjacent buildings to each frame.

[0002]

2. Description of the Related Art FIG. 7 is a cross-sectional view showing a conventional expansion joint device 1. FIG. 7 (1) shows a state in which the respective frames 2, 3 are relatively close to each other, and FIG. FIG. 7 (3) shows a state in which each of the skeletons 2, 3 is relatively separated from each other, and FIG. 7 (3) shows a state in which each of the skeletons 2, 3 is relatively displaced in a direction intersecting the approaching and separating directions. The expansion joint device 1 is provided over each of the skeletons 2 and 3 of the adjacent building with a gap to close the gap between the skeletons 2 and 3.

In the expansion joint device 1, mounting members 10 and 11 are provided at both ends of a panel holder 5 which can expand and contract, and the mounting members 10 and 11 are connected to hinge means 8 and 9 each having one hinge shaft. Each hinge axis L
1 and L2 so as to be freely angularly displaceable around the panel holder 5
Holds the cover panel structure 4. Each of the hinge means 8 and 9 can be angularly displaced by fitting a cylindrical fitting convex part into a C-shaped fitting concave part divided in the circumferential direction. The expansion joint device 1 is configured such that each of the frames 2, 3 is expanded and contracted by the expansion and contraction of the panel holder 5 and the angular displacement by the hinge means 8, 9.
However, the gap between the frame bodies 2 and 3 is closed by the cover panel structure 4 in a state where it can be allowed to be displaced in directions approaching and separating from each other and in a direction crossing this direction.

[0004]

In such a conventional technique, the panel holder 5 can be angularly displaced only around one hinge axis L1, L2 with respect to each of the frames 2, 3. In addition, the panel holder 5 is connected to each hinge axis L
The angle which can be angularly displaced around 1 and L2 cannot be set large in order to prevent the fitting projection from coming out of the fitting recess. Therefore, since the panel holder 5 cannot be displaced greatly with respect to each of the frames 2, 3,
The expansion joint device 1 cannot tolerate the displacement when each of the skeletons 2 and 3 is largely displaced in a direction intersecting the direction of relatively approaching and separating.

In order to seal the gap between each of the frames 2, 3 and each of the hinge means 8, 9 in a watertight manner, each of the frames 2, 3 and each of the mounting members 1 are mounted.
Although the sealing members 12 and 13 are struck between the mounting members 10 and 11, the mounting members 10 and 11 are members that are angularly displaced together with the panel holder 5. When the members 10 and 11 are angularly displaced, the respective sealing materials 12 and 1
3 is damaged by being compressed or pulled. Therefore, when each of the frames 2, 3 is displaced, the seal members 12, 13 are damaged, and the seal is broken.

SUMMARY OF THE INVENTION An object of the present invention is to provide a connecting structure for an expansion joint which can tolerate a large displacement in a direction intersecting a direction in which two skeletons relatively approach and separate from each other. It is.

According to a first aspect of the present invention, there is provided a panel which can be extended and contracted in a width direction by multiaxial hinge means having a plurality of parallel hinge axes on two adjacent frames with a gap. Both ends in the width direction of the holding body are connected to each other, and connected to the panel holding body in a state where the cover panel structure is resiliently biased in a direction of drawing the cover panel structure. A connecting structure for an expansion joint, wherein a panel guide portion is provided for guiding both ends in the width direction of the body to the outside of each hinge shaft.

According to the present invention, the extendable panel holder is connected to each frame by multi-axis hinge means,
For each frame, it can be angularly displaced about a plurality of hinge axes. The cover panel structure is connected to the panel holding body, and the gap between the respective frames is formed by the cover panel structure in a state where each frame can be displaced in the direction of approaching and separating, and in the direction perpendicular to this direction. Can be closed. Each multi-axis hinge means has a limit on the angle at which it can be angularly displaced around each hinge axis. However, even if the angular displacement around one hinge axis reaches the limit, it can be angularly displaced around another hinge axis. The angle that can be angularly displaced as a whole is an angle obtained by combining the angles that can be angularly displaced around each hinge axis, and is a large angle as compared with the case where there is one hinge axis. Therefore, the panel holder can make a large angular displacement with respect to each frame, and each frame is
Even if the displacement is large in the direction perpendicular to the relatively approaching and separating directions, this displacement can be allowed. Further, the cover panel structure is held in a state of being resiliently drawn to the panel holding body. In addition, the multiaxial hinge means is provided with a panel guide. As a result, when each frame is displaced in the approaching direction, both ends in the width direction of the cover panel structure are guided so as to ride on the outside of each hinge axis, and the cover panel structure holds the panel against spring force. It can be displaced in a direction away from the body. Therefore, even if the respective frames are displaced so as to be relatively close to each other, the cover panel structure is not crushed.

According to the first aspect of the present invention, the stretchable panel holder is connected to each frame by a multi-axis hinge means, and each panel has an angle around a plurality of hinge axes. Can be displaced. The cover panel structure is connected to the panel holding body, and the gap between the respective frames is formed by the cover panel structure in a state where each frame can be displaced in the direction of approaching and separating, and in the direction perpendicular to this direction. Can be closed. Each multiaxial hinge means
There is a limit on the angle that can be angularly displaced around each hinge axis, but even if the angular displacement around one hinge axis reaches the limit, it can be angularly displaced around the other hinge axis,
The angle that can be angularly displaced as a whole is an angle obtained by combining the angles that can be angularly displaced around each hinge axis, and is a large angle as compared with the case where there is one hinge axis. Therefore, the panel holder can be largely angularly displaced with respect to each frame, and even if each frame is largely displaced in a direction perpendicular to the direction of relatively approaching and separating, this displacement can be tolerated. . Further, the cover panel structure is held in a state of being resiliently drawn to the panel holding body. In addition, the multiaxial hinge means is provided with a panel guide. As a result, when each frame is displaced in the approaching direction, both ends in the width direction of the cover panel structure are guided so as to ride on the outside of each hinge axis, and the cover panel structure holds the panel against spring force. It can be displaced in a direction away from the body. Therefore, even if the respective frames are displaced so as to be relatively close to each other, the cover panel structure is not crushed.
