JPH10280564A - Expansion joint for external wall - Google Patents

Abstract

PROBLEM TO BE SOLVED: To prevent a panel from colliding with an external wall on an occasion of earthquake by a method wherein the panel is held, being capable of opening and shutting, at its end on one side at the external wall of a building on one side while being positioned at its end on the other side at the exterior-side of the external wall on the other side, and the end on the other side of the panel is connected to the external wall on the other side. SOLUTION: A paper-sliding door 5 is connected to the sides of external walls with connecting members 31. As buildings A and B on both sides sway in the direction wherein the distance d contracts on an occasion of earthquake, the left stile 6 is separated from the engaging groove 13 with the connecting member 31 on the left side kept in engagement with the engaging groove 15, and thereby the paper-sliding door 5 is kept under the state of safety. With the release of the connecting member 31 on this occasion, the paper-sliding door 5 is opened to the exterior-side through an arm, a roller and a receiving plate by a bouncing force of a torsion bar. When the buildings sway in the direction wherein the distance d expands, the left-side connecting member 31 is separated from the external wall-side engaging groove 15 while being kept in engagement with the engaging groove 13 of the paper-sliding door 5 and accordingly, the paper-sliding door 5 is opened by operation of the torsion bar. Thereby, the danger of collision between the panel and the external walls of the buildings can be eliminated.

3) to keep the sash (5) in a safe state without colliding with the outer wall of the building.
By releasing the connection of 1), the resilient force of the torsion bar (39) releases the shoji (5) to the outside of the room via the arm (40), the roller (42), and the passive plate (33), thereby forming the shoji. (5) is placed in a safer state without colliding with other members.

The distance between the two buildings (A) and (B) is (d).
FIG. 9 (b) when is swung in the direction to expand to (d ₂ ).
The outer wall is disengaged from the engagement groove (15) while the left connecting member (31) is engaged with the engagement groove (13) of the shoji (5) as shown in FIG. 5) Release.

Next, both buildings (A) and (B) are shown in FIG.
As shown in (a) or (b), when swinging in opposite directions in the indoor / outdoor direction, the connecting member (31) on the left side is engaged with, for example, the outer wall engagement groove (15) and the sash ( 5) Disengage from the glue engagement groove (13) to release the connection, and at the same time, release the shoji (5) by the torsion bar (39).

In addition to the above, even in the case of various types of shaking of FIG. 9 and FIG. 10, the connection member (31) is disconnected and the shoji (5) is opened according to the above example to keep the shoji safe. When the earthquake has subsided, the shoji (5) is closed, and the connecting member (31) is engaged and connected in its original state.

[0028]

According to the first and second aspects of the present invention,
When the earthquake occurs, by disengaging the connection means, the panel shall be free from the influence of shaking of the two buildings in the opposite direction, with the other end of the panel positioned outside of the outside wall of the other building. Thus, the danger of collision between the panel and the building outer wall can be eliminated, thereby making it possible to use glass for the panel and the building outer wall.

According to the third aspect of the present invention, in addition to the effects of the first and second aspects, when the connection of the connecting means is released at the time of an earthquake, the panel is positively opened by the elastic material. This allows the panel to be spaced farther away from the other components, thus further securing the panel and other components.

According to the invention of claim 4 of the present application, in addition to the effect of the invention of claim 1 or 2 or the effect of the invention of claim 3, even if the building shakes up and down when an earthquake occurs,
The pivotal support between the long shaft projecting upward from the upper end of the panel and the bearing member is maintained, and the pivotal support of the panel can always be ensured.
