Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a joint for floor covering a floor having a wall surface on one side such as a corridor or a veranda of right and left buildings built through joints. Related to the device. 2. Description of the Related Art Conventionally, a floor joint device for covering a floor portion such as a crossing corridor or a veranda has a concave portion formed on the left and right floor surfaces on the joint portion side, and a pair of ground rails fixed to the concave portion, A joint plate that covers an joint portion whose both ends are slidably supported by the pair of base rails; and a pair of the base rails that cover both end portions of the joint plate so that the joint plate can slide. And a pair of cover plates attached to the cover plate. [0003] The conventional joint device for floors has a drawback that it cannot be installed unless base rails having recesses are formed on the left and right floor surfaces on the joint portion side. The joint plate moves to one side when it shakes due to an earthquake, etc., and has the drawbacks of being dangerous or not being able to move smoothly. In the case of swinging in the direction, there is a disadvantage that the joint plate is pushed outward by the wall on one side. The present invention has been made in view of the above-mentioned conventional drawbacks,
The center part of the joint plate is always located almost at the center of the joint part, and when the left and right buildings swing in different front and rear directions, the sliding joint plate slides while overlapping the joint plate, causing an earthquake, etc. It is an object of the present invention to provide a joint device for floors that can efficiently absorb a swinging motion and eliminate problems such as a gap or joint putt protruding outward. The foregoing and other objects and novel features of the 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. SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides both ends of a left and right building having a joint wall having a wall on one side. A joint plate that covers the joint on the opposite side that is slidably supported, and holds the center of the joint plate so that it is always located at the center of the joint. A center maintenance mechanism pivotally supported by the building and the other end pivotally supported by the other building, and both ends capable of slidably overlapping the joint plate are provided on the joint side of the left and right buildings. A slide joint plate that covers the joint part of the one side part slidably supported, and biases the slide joint plate so as to always contact the one side wall surface,
A rear end portion is attached to a center portion of the joint plate or a center portion of the center maintaining mechanism, and a biasing mechanism using a support arm whose front end projects in a direction between the one side wall surfaces, the joint plate and the urging mechanism. A floor joint device is constituted by a pair of cover plates attached to the joint-side floor surface which covers both ends so that the slide joint plate can slide. Hereinafter, the present invention will be described in detail with reference to embodiments shown in the drawings.

One end is pivotally supported by one building 3 by a pivot pin 5 and the other end is A center maintaining mechanism 6 pivotally supported by a pivot pin 5 on the other building 3, and both ends capable of slidably overlapping the joint plate 4 are floor surfaces on the joint side of the left and right buildings 3, 3. 3b, 3b
A joint plate 7 for covering the joint portion of the one side portion slidably supported on the side surface; an urging mechanism 8 for urging the slide joint plate 7 to always contact the wall surface of the one side; The joint plate 4 and the slide joint plate 7 are constituted by a pair of cover plates 9, 9 attached to the joint-side floor surfaces 3 b, 3 b that cover both ends so as to be slidable. The joint plate 4 is, as shown in FIG.
A joint plate main body 10 that covers almost half of the joint portion 2 in the front-rear direction, and a slide using one of a plurality of protrusions and ball rollers attached to the bottom surface near both ends of the joint plate main body 10. It is composed of moving bodies 11 and 11. [0010] As shown in FIG.
A rectangular cylindrical pinion holder 13 to which a pair of pinions 12, 12 fixed to a central portion on one side of the joint plate 4 is rotatably mounted;
A pair of racks whose front ends are slidably movable and the rear ends of which mesh with the pair of pinions 12, 12 are pivotally supported on floor surfaces 3b, 3b of the left and right buildings 3, 3 by pivot pins 5, 5, respectively. 14 and 14. As shown in FIG. 6, the slide joint plate 7 has a slide joint plate main body 15 formed so as to overlap at least half of the joint plate 4, and both ends on one side of the slide joint plate main body 15. Multiple protrusions and ball rollers attached to the bottom
Slide moving body 16, 1 using any of rollers or the like
6. As shown in FIG. 7, one end of the urging mechanism 8 is fixed to the center of the joint plate 4 or to the pinion holder 13, and the other end is the wall 3a of the left and right buildings 3, 3. 3a, and the slide joint plate 7 which is interposed between the distal end of the spring support arm 17 and the center of one side of the slide joint plate 7 is always attached to the wall surface 3a. ,
A biasing spring 18 for biasing to abut on 3a;
The slide joint plate 7 includes guide pieces 19 and 19 which are engaged with the spring support arm 17 attached to the center of one side of the slide joint plate 7. As shown in FIG. 8, the pair of cover plates 9, 9 are formed in a plate-shaped cover plate main body 20, and are sequentially formed integrally with one end of the cover plate main body 20 so as to protrude downwardly to form a floor surface 3 b. The guide piece 21 of the inclined surface which comes into contact
And a triangular attachment which is fixed with a plurality of anchor bolts 23 to floor surfaces 3b, 3b outside of the pair of racks 14, 14 for fixing the guide piece 21 with a plurality of screws 22. Tool 24. When the left and right buildings 3 and 3 swing due to an earthquake or the like and the joint 2 swings in the left and right direction so as to widen, the floor jointing device 1 having the above-described structure has a center of the joint plate 4 as shown in FIG. The pair of racks 14 and 14 move so as to protrude from the pinion holder 13 while maintaining the state where the portions are positioned at the center of the joint portion 2, and absorb the swinging motion. At this time, since the slide joint plate 7 is engaged with the spring supporting arm 17 fixed to the center of the joint plate 4 by the guide pieces 21, similarly, the center of the slide joint plate 7 is the center of the joint 2.
