Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a foldable exterior body attached to a space between buildings.

[Problems to be solved by conventional technology and device]

Conventionally, a so-called expansion joint is often used as an exterior body interposed between skeletons. That is, the structure is such that an edge material is attached to the frame side, and a plate material is abutted between both edge materials of both frame members so as to slide and tilt freely. This type of structure has a problem that it cannot sufficiently cope with vibrations such as an earthquake in which the clearance between the two frames greatly changes.

Therefore, the present invention solves the above problems, and provides a foldable exterior body that is not sufficiently destroyed even when the distance between buildings greatly changes due to a typhoon earthquake or the like, and further, has less rattling. It is an object.

[Means for solving the problem]

In order to achieve the above object, the present invention provides a folding partition wall which is arranged between respective frames of opposing buildings and is connected to a plurality of partition walls alone so as to be swingable with hinges. An auxiliary member disposed between the frames and capable of being displaced in the left-right and front-rear directions, and a rear end attached to a part of the auxiliary member at a predetermined position and a front end attached to a predetermined hinge of the folding partition wall, Further, a resilient tension member for resiliently urging the folding section wall rearward is provided.

[Action]

If the distance between buildings greatly changes due to an earthquake,
The partition wall itself swings around the hinge and opens and closes to fold and unfold, and follows. In addition, even in the case where the frame oscillates in the opposite parallel direction while keeping the mutual interval constant, it can be absorbed by the swing between the partition walls alone. The auxiliary member follows (absorbs) similarly, but a resilient tension member is interposed between the auxiliary member and the folding partition wall, and the restoring force of the folding partition wall to return to the expanded state. Is generated.

〔Example〕

 Hereinafter, the present invention will be described in detail based on the illustrated embodiment.

FIG. 1 shows an embodiment of the foldable exterior body according to the present invention. The foldable exterior body is composed of respective frames 1 of buildings 1 and 2 facing each other.
A folding partition wall 3 disposed between the frames 13 and 14; a pantograph-type auxiliary member 5 disposed between the frames 13 and 14; And tension members 4, 4. Reference numeral 6 denotes a water stop plate for preventing water from entering between the buildings 1 and 2, and reference numeral 7 denotes a fire-resistant zone prepared for a fire or the like.

The folding section wall 3 is composed of a plurality of section walls 20.
Are connected so that they can swing in the horizontal direction. The partition wall alone
20 panels 11 are made of aluminum casting or ceramic.
The backing plate 10 is provided with band-shaped reinforcing members 12. In the present embodiment, two pairs of partition walls 20 and 20 connected by a special hinge 8 (19) having a mounting rod 22 are produced.
The center of the two sets is connected by a special hinge 9 attached to a three-point pivot to form a foldable partition wall 3 (see FIG. 4). The left and right ends of the folding section wall 3 are hinged at 8,8 via frame-side fixing members 15,16 made of, for example, aluminum or stainless steel.
Fixed to 3,14. In addition, each hinge 8…
Stoppers 18 are fixed to alleviate the impact when closed.

As shown in FIG. 2, the pantograph-type auxiliary member 5 is formed by superposing a plurality of band plate members 23 on each other and swingably pivoting with screws or the like. Therefore, the auxiliary member 5 is foldable and expandable in the left-right direction, and the left and right ends thereof are fixed to the frames 13 and 14 with the attachment members 21 and 21 formed of hinges. Since the auxiliary member 5 has the attachment members 21 and 21 formed of the hinges, the relative displacement of the frames 13 and 14 in the front-rear direction can be tolerated. The rear ends of the elastic tension members 4, 4 are connected to a part of the front surface of the auxiliary member 5 at a predetermined position, that is, a position facing the special hinges 8, 8 (19, 19). For example, a coil spring is used for the tension members 4, 4, and the front end thereof and the attachment rods 22, 22 of the special hinges 8, 8, (19, 19) are connected by connection wires 17, 17, respectively. ing.

When the clearance between buildings 1 and 2 changes due to an earthquake or the like (FIGS. 3 and 4 show a case where the gap is reduced), the folding partition wall 3 is composed of a plurality of partition walls 20 in a horizontal direction. To expand and contract freely. In addition, the pantograph type auxiliary member 5
Also expands and contracts freely in the left, right, front and rear directions. Elastic tension member 4,
4 expands and contracts in the front-rear direction with the movement of the special hinges 8,8 (19,19). When the earthquake or the like subsides, the tension members 4, 4 restore the normal state shown in FIG.

It should be noted that the present invention is not limited to the above-described embodiment, and the design can be freely changed without departing from the gist of the present invention.

[Effect of the invention]

Since the present invention is configured as described above, it has the following significant practical effects.

In the event of an earthquake, etc., the increase or decrease in the clearance of buildings 1 and 2 can be absorbed sufficiently without being destroyed. Further, it can be surely restored to the normal state. In addition, by the action of the auxiliary member 5 and the elastic tension members 4, 4, rattling of the folding section wall 3 can be reduced, and a normal state can be restored.
