Description

  The present invention relates to a joint cover device that can use joints of left and right buildings built via joints as a passage in normal times.

Conventionally, seismic isolation buildings, etc. use joint plates that are almost twice as large as joints so that the rear end is fixed to the floor frame of the passage of one building and the front end slides on the passage of the other building. ing.

For this reason, a large joint plate is required, so that the installation work is difficult and the cost is high.
In addition, there is a drawback in that the installation at a site that is used only occasionally as a passage on the joint plate becomes excessive equipment.
Japanese Patent No. 3123356

    In view of the conventional drawbacks as described above, the present invention uses a joint plate that is smaller than the size of the joint part, and can be used as a passage space at normal times, even if the left and right buildings are swung so that the joint part is narrowed. It aims at providing the joint cover apparatus which does not damage a plate and an outer wall surface.

The above and other objects and novel features of the present invention will become more fully apparent when the following description is read in conjunction with the accompanying drawings.
However, the drawings are for explanation only and do not limit the technical scope of the present invention.

In order to achieve the above-mentioned object, the present invention provides a front end portion that is pivotally attached to a housing near a floor surface serving as a passage on the outer wall surface of one building via a hinge member, in the vicinity of the outer wall surface of the other building. A joint plate projecting to the top, a support base for supporting the tip of the joint plate, which is fixed to the outer wall surface of the other building so that the joint plate can be supported in a substantially horizontal state, and the tip of the joint plate One end portion is pivotally supported on the bottom surface near the portion, and the other end portion is pivotally supported on the outer wall surface of one building at the lower position of the hinge member, the joint plate can be supported in a substantially horizontal state, and the joint portion is The joint cover device is composed of at least two extendable legs that can rotate without causing the joint plate to collide with the outer wall surface of the other building while being expanded by the pressing force applied to the support base when it becomes narrow. .

  As is clear from the above description, the present invention has the following effects.

(1) A joint plate in which a front end portion rotatably attached to a housing near a floor surface serving as a passage on the outer wall surface of one building via a hinge member protrudes to the vicinity of the outer wall surface of the other building; A support base for supporting the tip of the joint plate fixed to the outer wall surface of the other building so that the joint plate can be supported in a substantially horizontal state, and one end on the bottom surface near the tip of the joint plate The joint plate is pivotally supported, and the other end is pivotally supported on the outer wall surface of one building at the lower position of the hinge member. The joint plate can be supported in a substantially horizontal state. It is composed of at least two extendable legs that can rotate without causing the joint plate to collide with the outer wall surface of the other building while being stretched by pressure. Covering It can be used as a passage.

(2) According to the above (1), even if the joint becomes wide due to an earthquake, the joint plate can be kept almost horizontal with at least two telescopic legs, and even if there is a person on the joint plate, it is safe. Can be secured.

(3) When the joint portion becomes narrow due to the earthquake according to (1), at least two or more extendable legs are pressed against the support base, and the tip portion of the joint plate moves upward without colliding with the outer wall surface of the other building. It can be rotated to absorb the shaking movement.
Accordingly, it is possible to efficiently prevent damage to the outer wall surface and joint plate of the other building.

(4) According to the above (1), the structure is simple and can be easily installed.

(5) According to the second aspect, the road can be surely moved upward without damaging the joint plate.

  Hereinafter, the present invention will be described in detail with reference to the best mode for carrying out the invention shown in the drawings.

  1 to FIG. 6, in the first preferred embodiment for carrying out the present invention, reference numeral 1 denotes one building 2, a rooftop parapet 3 serving as an outer wall surface, and the other building provided via a joint portion 4. 5 is a joint cover device of the present invention provided so that it can be used as a passage between the outer wall surface 5a and the joint cover device 1 in the upper part on the joint part side of the parapet 3. A distal end portion rotatably attached via a hinge member 6 composed of a movable hinge member 6a and a fixed hinge member 6b formed in an angled shape is arranged near the outer wall surface 5a of the other building 5. The projected joint plate 7 and the outer wall surface 5a side that supports the tip of the joint plate 7 fixed to the outer wall surface 5a of the other building 5 so that the joint plate 7 can be supported in a substantially horizontal state. The top surface of the One end is pivotally supported by a pivot bracket 11 using a pivot pin 10 on the bottom surface near the tip of the support plate 9 formed on the surface 8 and the joint plate 7, and the other end of the hinge member 6. The joint plate 7 pivotally supported by the pivotal support metal 13 using the pivotal support pin 12 on the outer wall surface 2a of one of the buildings 2 at the lower position can be supported in a substantially horizontal state. The joint plate 7 is composed of at least two extensible legs 14 and 14 that can be rotated without causing the joint plate 7 to collide with the outer wall surface 5a of the other building 5 while being stretched by the pressing force to 9. .

  As shown in FIG. 4, the at least two or more extendable legs 14, 14 are rod-like fixed leg members 16 each having a pivot pin insertion hole 15 formed at the lower end, and are slidable to the fixed leg members 16. A movable leg member 18 having a pivot pin insertion hole 17 formed at the upper end attached thereto, and a tip end portion of the joint plate 7 fixed to a lower portion of the fixed leg member 16 are attached to the support base 9. The stopper 19 is in contact with the lower end of the movable leg member 18 in a supported state.

As shown in FIG. 1 and FIG. 2, the joint cover device 1 having the above-described configuration normally has the joint portion 4 covered with a joint plate 7 supported by a support base 9. It can be used as a passage when moving to the building 5.
Further, when the joint part 4 is swung so as to become wide due to the earthquake, the joint plate 7 is separated from the support base 9 as shown in FIG. 5, but the load is applied to the joint plate 7 by at least two extensible legs 14 and 14. Even in the state where is added, it is supported so that it remains almost horizontal.
For this reason, when the shaking motion stops, the state automatically returns to the state shown in FIG.
When the joint 4 is swung so as to become narrow due to the earthquake, as shown in FIG. 6, at least two movable leg members 18, 18 of the telescopic legs 14, 14 come into contact with the tip of the support base 9, Since it is pushed in the direction of the building 2 and turns, the tip of the joint plate 7 turns upward, and the tip of the joint plate 7 turns upward without colliding with the outer wall surface 5a of the other building 5. Can absorb shaking motion.
At this time, since the pivotal support portion of the hinge member 6 is located at the lower position of the joint plate 7, the upward rotation of the tip portion of the joint plate 7 can be smoothly performed without damaging the joint plate 7.
When the shaking motion is stopped, at least two of the telescopic legs 14 and 14 are contracted by the weight of the joint plate 7 and automatically return to the state of FIG. 3 in which the tip of the joint plate 7 is supported by the support base 9. .
