Description

  The present invention relates to a floor joint device that covers a space between right and left floor frames provided via joint portions.

  Conventionally, this type of floor joint device is formed with a joint plate slide concave portion on the other joint side floor surface, a rear end portion is attached to one joint portion side floor frame, and a front end portion is formed on the joint plate slide concave portion. A joint plate supported so as to be slidable is positioned, and the joint plate located in the joint plate slide recess is covered with a cover plate.

  However, the floor joint device constructed in this way can absorb shaking movements where the joint part is widened or narrowed by an earthquake, but the height of the left and right floor frames is increased due to uneven settlement. If they are different, the cover plate is pushed up by the joint plate, which is dangerous.

A screw insertion hole 17 for fixing with a tapping screw 16 or the like, and an upper roller 18 attached to the upper inner wall of the distal end portion of the support arm main body 12.

  As shown in FIG. 6, the plurality of insertion support arms 5 include a plate-like or cylindrical insertion support arm main body 19 that is slidably inserted into the plurality of cylindrical support arms 4, respectively. A lower roller 20 attached to the lower end of the distal end of the insertion support arm main body 19, a mounting portion 21 formed so as to protrude outwardly from an upper end of the rear end of the insertion support arm main body 19, and pivotally supported by the mounting portion 21. A bracket 24 having support pieces 23 and 23 pivotally supported by pins 22 and screws formed at both ends of the bracket 24 and fixed to the other joint portion side floor frame 3 with tapping screws 25 and 25, etc. It is composed of insertion holes 266 and 26.

  The one cover plate 6 is fixed by screws 28 to a plurality of angle-shaped attachment members 27 fixed to the upper side walls of the plurality of cylindrical support arms 4.

  The other cover plate 7 is formed with an inclined surface 29 at the front end, and the rear end is a spacer at the rear end of the plurality of insertion support arms 5 so that the other cover plate 7 is substantially horizontal. 30 is fixed.

  The guide member 8 includes a crank-shaped lower guide rail 31 fixed to the lower part of the plurality of cylindrical support arms 4 by welding or a plurality of screws, and the plurality of the guide members 8 at positions above the lower guide rail 31. A crank-shaped upper guide rail 32 fixed to the upper wall of the cylindrical support arm 4 by welding or a plurality of screws.

  The support plate 9 includes a support plate main body 34 juxtaposed with the insertion support arm 5 via a connecting member 33 at the rear end of the plurality of insertion support arms 5, and a bottom surface of the front end portion of the support plate main body 34. A roller 35 that rolls on the lower guide rail 31 and an engagement piece 36 that engages with the upper guide rail 32 that is attached to the upper portion of the tip of the support plate body 34. It consists of and.

  The load support mechanism 11 is attached to the support plate main body 34 at predetermined intervals, and is attached to a plurality of support arms 38 that are pivotally supported by pivot pins 37, and to the front ends of the support arms 38, respectively. In addition, the roller 39 that contacts the bottom surface of the other cover plate 7 and the plurality of support arms 38 are in a substantially vertical state, and are fixed to the support plate body 34 that can rotate when pressed by the one cover plate 6. A plurality of stopper pieces 40, and one end for urging the plurality of stopper arms 40 so that the plurality of support arms 38 abut against each other are attached to a portion near the rear end of the support arm 38; A plurality of urging springs 41 whose other ends are attached to a portion near the upper portion of the support plate main body 34 and the support arms 38 are prevented from blocking the operation of the support arms 38. To prevent deformation of 8, and a reinforcement cover 43 in which the support plate a plurality of support arms insertion hole 42 at the top which is attached to the main body 34 is formed.

  The floor joint device 1 having the above-described configuration normally contacts the upper roller 18 and the lower roller 20 of the plurality of insertion support arms 5 whose tip portions are slidably inserted into the plurality of cylindrical support arms 4. The cover part is covered with one cover plate 6 and the other cover plate 7 which are supported in a straight line.

  In this state, the bottom surface of the other cover plate 7 is supported by a plurality of load support mechanisms 11 and efficiently prevents the other cover plate 7 from being bent even when a load is applied.

  When the left and right floor frames 3 and 3 are swung so that the joint portion 2 is narrowed by the earthquake, a plurality of insertion support arms 5 enter the plurality of cylindrical support arms 4 as shown in FIG. Since the support plate 9 also moves together with the insertion support arm 5, when the rollers 39 of the plurality of load support mechanisms 11 come into contact with one cover plate 6, the support arm resists the biasing force of the biasing spring 41. 38 is rotated to release contact with the bottom surface of the other cover plate 7 to prevent the support arm 38 from being damaged.

  When the left and right floor frames 3 and 3 are swung so that the joint portion 2 is widened by an earthquake, the plurality of insertion support arms 5 slide out from the plurality of cylindrical support arms 4 as shown in FIG. At the same time, since the support plate 9 also moves together with the plurality of insertion support arms 5, the rollers 39 of the plurality of load support mechanisms 11 are kept in contact with one cover plate 6, and the other cover plate 7 is attached to the other cover plate 7. Prevents bending when a load is applied.

  When the left and right floor frames 3 and 3 sink unevenly due to the earthquake, as shown in FIG. 10, the rear end portions of the plurality of cylindrical support arms 4 are connected to the floor frame 3 on one joint portion side as pivot pins 14. When the rear end portions of the plurality of insertion support arms 5 are attached to the floor frame 3 on the other joint portion side via the pivot pins 22, the pivot pins 14 and 22 are connected to each other. It is possible to rotate and absorb the swaying motion, and to prevent one cover plate 6 and the other cover plate 7 from entering a dangerous state in which a gap is generated by the swaying motion.

  Further, when the rear end portions of the plurality of cylindrical support arms 4 are fixed to the floor frame 3 on one joint portion side, the plurality of cylindrical support arms 4 are positioned downward. In this case, the tip of the other cover plate 7 is in contact with one cover plate 6 to prevent danger, but when moving in the opposite direction, the other cover plate 7 is more than the one cover plate 6. Will be in a state of projecting upward.

In addition, when the shaking motion of the left and right floor frames 3, 3 in the earthquake stops, the original state is automatically restored.
