Description

  The present invention relates to a joint device for closing joint portions between casings provided via joint portions.

  Conventionally, when a joint portion becomes narrow due to an earthquake, the joint plate can be simply slid on the floor surface to absorb the shaking motion, and the joint plate of the joint device is provided with a handrail as a safety measure. The thing is known (for example, patent document 1).

  However, in a joint device in which a joint plate slide supporting recess having an inclined surface is formed in the housing and the joint portion becomes narrow due to an earthquake, the joint plate rides on the inclined surface and absorbs the shaking motion. The handrail is destroyed by the displacement. On the other hand, even if the handrail is installed in a part that does not affect the displacement of the joint plate (between the handrail members of the housing), if the housing shakes due to an earthquake, the handrail and the joint plate or the floor of the housing There was a danger that gaps were created and people and objects dropped out.

The central beam member 9 is a component of the central maintaining mechanism 8 as described above, and is fixed so as to be positioned at the central portion of the joint portion 2 by the connection pin 16 provided on the central pivot portion 7 of the bar member 15. The

  The total length of the beam body 17 is preferably longer than the width (the length of the joint in the longitudinal direction) where the joint plates 10 are installed. Further, in the present embodiment, the connection pin 16 provided on the central pivot 7 and the pivot pin 18 whose tip is fixed to the central portion of the bottom surface of the joint plate 10 are integrally formed. These may be provided separately.

  The joint plate 10 is a metal plate joint plate body 19 having a rectangular shape in a plan view, a mortar or concrete 20 filled in the joint plate body 19, and affixed to the upper surface of the mortar or concrete 20. Fixed floor tiles 21 such as tiles such as marble and bricks, cover plates 22 attached to both sides of the joint plate body 19 on the housing side via hinges 14, and fixed to the bottom center of the joint plate body 19 It is comprised with the said pivot pin 18 made.

Of the joint plate 10, for example, a joint plate 10 </ b> A located at an end shown in FIGS. 1, 5, 7, and 11 has a notch-shaped main pillar passage portion 23 through which the main pillar 11 passes. Is formed. In the present embodiment, the main column passage portion 23 is a recess-shaped notch formed in the side portion of the joint plate 10A, but may be a hole having a shape through which the main column 11 can pass.
In the present embodiment, the main pillar 11 is formed in a square bar shape having a rectangular cross-sectional view and a front view rectangular shape, and a lower end portion is fixed to the central beam member 9 and is positioned above the joint plate. A handrail 12 is fixed to the part to be operated.

  The handrail 12 is formed with a main pillar insertion hole 24, a plate-shaped handrail main body 25 having a rectangular shape in front view attached by inserting the main pillar 11 into the main pillar insertion hole 24, A connecting member having one end portion rotatably connected to both end portions and the other end portion being rotatably connected to the handrail member 3b of one housing 3 or the handrail member 4b of the other housing 4 26.

  In addition, it is good to provide the U-shaped guide member 27 in the vicinity of the both ends (front-end | tip part and rear-end part) of said joint plate 10A so that the said handrail main body 25 can maintain a parallel state with 10 A of joint plates.
