Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a floor joint device that is formed integrally with one building at at least one end portion of a right and left building that is built via a joint portion and covers a floor joint portion of a portion having a wall surface.
[0002]
[Prior art]
Conventionally, this type of floor joint device is a joint plate using a joint plate that covers the joint portion, and at least two pantograph-shaped link mechanisms in which the center portion of the joint plate is always located at the center portion of the joint portion. It consists of a central maintenance mechanism.
[0003]
[Problems to be solved by the invention]
Since the conventional floor joint device uses a joint plate center maintaining mechanism using a pantograph-shaped link mechanism, when using a relatively light joint plate, the joint plate is placed in the center of the joint portion as intended. However, in the case of a joint plate that fixes mortar in the plate-shaped joint plate body and fixes floor materials such as tiles, the joint plate is heavy and joints using a pantograph-shaped link mechanism are used. The plate center maintaining mechanism has a drawback that the joint plate cannot be smoothly slid.
Also, a joint using a support bar arranged in an inclined state, with one end pivotally supported on the floor frame of one building and the other end slidably mounted on a rail attached to the floor frame of the other building If the plate center maintenance mechanism is used, the joint plate can be slidably supported even with a heavy joint plate, but when the joint portion becomes wider or narrower, the joint plate changes in the front-rear direction. There was a drawback that the slide movement by half the size of the dimension caused a gap at the end or damage by colliding with the wall surface.
[0004]
In view of the conventional drawbacks as described above, the present invention can smoothly slide even a heavy joint plate, and the joint part is widened, and even if it becomes narrow, no gap is generated at the end part. It aims at providing the joint device for floors which can be used safely.
[0005]
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.

The end joint plates 10 and 10 overlap each other by a predetermined amount, and the end joint plates 10 and 10 are always provided with wall surfaces 4 and biasing mechanisms 12 and 12 using biasing springs 11 and 11 that bias the four directions. ing.
[0009]
As shown in FIG. 4, the dish-shaped joint plate 7 is a dish made of a metal material having both side portions formed on inclined surfaces 13 and 13 that can come into surface contact with the inclined surfaces 5 and 5 of the pair of recesses 6 and 6. A joint plate main body 14 formed in a shape, a mortar or concrete 15 filled in the joint plate main body 14, and a floor material 16 such as a tile or a floor covering material installed on the top surface of the mortar or concrete 15. Has been.
[0010]
As shown in FIG. 5, the joint plate center maintaining mechanism 9 has a rail 17 fixed substantially horizontally to the floor frame 3 a on the joint 2 side of one building 3, and one end of the rail 17 can be slid. A tilted state in which the other end is pivotally supported by the pivot pin 19 on the mounting bracket 18 fixed to the floor frame 3a on the joint portion side of the other building 3, in the embodiment of the present invention, an inclination of 45 degrees At least two or more support bars 8, 8 arranged in the above, a reinforcement bar 21 pivotally supported by pivot pins 20, 20 at substantially the center of the at least two support bars 8, 8, and this reinforcement The plurality of support rods 22 are pivotally supported by the bar 21 so as to be movable up and down, and are respectively fixedly attached to substantially the center portions of the plurality of joint plates 7.

As shown in FIG. 6, the end joint plates 10, 10 protrude upward from one end of the plate-like end joint plate main body 23 made of a metal material, and the end joint plate main body 23. And a cover plate 25 that covers the opening 24.
[0012]
As shown in FIG. 7, the urging mechanisms 12 and 12 are provided so as to penetrate through holes 26 formed at positions near the lower part of the center part of the outer wall surfaces 7 a of the joint plates 7 and 7 at both ends. The guide cylinder 27, the urging spring 11 housed in the guide cylinder 27, one end of the guide cylinder 27 slidably inserted into the guide cylinder 27, and the other end attached to the end joint plate 10 It is comprised with the pressing pin 29 fixed via 28. FIG.
[0013]
When the left and right buildings 3 and 3 are swung so that the joint portion 2 becomes narrow due to an earthquake or the like, the floor joint device 1 having the above-described configuration is caused by the joint plate center maintaining mechanism 9 as shown in FIGS. 8 and 9. Since the center portions of the plurality of joint plates 7 are maintained at the center portion of the joint portion 2, both side portions of the plurality of joint plates 7 are pushed upward by the inclined surfaces 5, 5 of the pair of recesses 6, 6. On the other hand, it rides on the left and right floor frames 3a, 3a and absorbs the shaking movement.
At this time, since the support bars 8 and 8 of the joint plate center maintaining device 9 are rotated so that the inclination angle of the support bars 8 and 8 is increased, the half of the size of the joint portion 2 is reduced. It moves in the front-rear direction at the center, and slides the plurality of joint plates 7 in that direction.
Even when the plurality of joint plates 7 move in the front-rear direction, the end joint plates 10 and 10 are urged in the directions of the wall surfaces 4 and 4 by the urging mechanisms 12 and 12, and the wall surfaces 4 and 4 and the end joint plates are urged. It is possible to reliably prevent a gap from being generated between 10 and 10.
[0014]
When the joint portion 2 becomes wider, as shown in FIGS. 10 and 11, both end portions of the plurality of joint plates 7 slide on the pair of recesses 6 and 6, and the shaking motion is the same as described above. Absorb.
[0015]
When the left and right buildings 3 and 3 swing in different front and rear directions, the end joint plates 10 and 10 are always wall surfaces by the elastic force of the biasing springs 11 and 11 of the biasing mechanisms 12 and 12, as shown in FIG. The swaying motion can be absorbed while maintaining the state of being urged so as to abut against the fourth and fourth members.
[0016]
