Description

  The present invention relates to a floor joint device for covering joint portions of left and right housings including left and right buildings provided via joint portions.

  Conventionally, when the joint between the left and right housings becomes narrow due to an earthquake in the floor joint device, the tip of the floor joint plate that covers the joint is slid so that it is pushed upward, which is dangerous. The rising plate formed with an inclined surface in which the rear end portion of the floor joint plate is fixed to the rear bottom surface of the floor joint plate is pushed upward using a lifting mechanism using a lifting bar.

  However, the floor joint device configured as described above moves the floor joint plate upward by moving the lift bar along the inclined surface of the lift plate. Because a large force is applied to the floor plate, the structure must have a sufficient strength, and the raised plate must be fixed to the bottom surface of the floor joint plate. There was a drawback that it was difficult to install.

  Hereinafter, the present invention will be described in detail with reference to the embodiments shown in the drawings.

  In the first embodiment for carrying out the present invention shown in FIG. 1 to FIG. 9, 1 is for the floor of the present invention covering between the left and right housings 3, 3 including the right and left buildings provided via the joint portion 2. The floor joint device 1 is a width dimension L of the joint portion 2 formed on the joint portion side floor surface of one of the left and right housings 3, 3 and the joint portion 2 formed on the inclined surface 4. The joint plate slide support recess 5 formed in substantially the same width dimension, the joint plate support recess 6 formed on the joint part side floor of the other housing 3 corresponding to the joint plate slide support recess 5, and the joint plate A floor joint plate 7 having a rear end portion supported by the support concave portion 6 and a front end portion covering the joint portion supported by the joint plate slide support concave portion 5, and a rear end portion of the floor joint plate 7 for the floor The tip of the joint plate 7 can be rotated upward The fixture 8 attached to the joint plate support recess 6 of the other housing 3 and the left and right housings 3 and 3 are narrowed by the earthquake, and the tip of the floor joint plate 7 extends along the inclined surface 4. When it moves upward, it is comprised with the floor joint plate pushing-up apparatus 9 which pushes up a rear part upwards.

  As shown in FIG. 2, the floor joint plate 7 includes a floor joint plate body 10 formed of a metal material in a shallow dish shape, and hinge members 11 on the front and rear upper portions of the floor joint plate body 10. Cover plates 12 and 12 that are rotatably mounted through 11, mortar and concrete 13 filled in the floor joint plate body 10, and installed on the top surface of the mortar and concrete 13 as necessary. It is comprised with the floor decorative boards 14, such as bricks and tiles.

  The mounting tool 8 has engaging pin storage boxes 15 and 15 whose bottom surfaces are open at the rear of both sides of the floor joint plate 7, and a head 16 a is inserted into the engaging pin storage boxes 15 and 15. The joint plate 7 includes engaging pins 16 and 16 fixed to the other housing 3 of the joint plate support recess 6 so as to be able to vertically move the joint plate 7.

  The floor joint plate push-up device 9 includes a support base 18 made of an angle material fixed to the other housing 3 at the lower position of the rear center portion of the floor joint plate 7 by a plurality of anchor pins 17, and the support base. A guide cylinder 22 in which notches 21 and 21 are formed on an inclined surface 19 and a vertical surface 20 serving as a stopper on a corresponding outer periphery fixed to the upper surface of 18, and can rotate in the guide cylinder 22 and slide upward. A push-up rod 23 that can move and push up the rear portion of the floor joint plate 7, and one end portion is fixed to the push-up rod 23 through the notch 21, and the other end portion of the one frame 3. When the joint portion is brought into contact with the joint portion side portion at an angle smaller than a right angle and the joint portion becomes narrow due to an earthquake, the push rod 23 is pushed upward by moving along the inclined surface 19 of the notch 21. The guide piece that contacts the inclined surface 19 of the notch 21 in the same manner as the arm 24 is in contact with the inclined surface 19 of the notch 21. 25, the arm 24 comes into contact with the vertical surface 20 as a stopper of the notch 21 at an angle position smaller than a right angle, and the arm 24 smoothly moves with the pressing force of one housing 3 in the shaking movement at the time of earthquake. It is set so that it can rotate.

  In the embodiment of the present invention, the floor plate joint plate 7 is directly installed in the joint plate slide support concave portion 5 or the joint plate support concave portion 6. However, the present invention is not limited to this, and the joint plate is formed as necessary. The upper surfaces of the plate slide support recess 5 and the joint plate support recess 6 may be covered with a metal base material.

  As shown in FIGS. 1 and 2, the floor joint device 1 having the above structure is normally covered with a floor joint plate 7 at the joint portion 2 between the left and right housings 3 and 3 so that it is covered in a substantially identical state. The vehicle can pass safely.

  When the width dimension of the joint portion 2 becomes narrow as shown in FIG. 8 due to an earthquake, the left and right housings 3 and 3 approach each other, so that the upper end portion of the floor joint plate 7 is the floor joint plate slide support recess 5 and the inclined surface 4. And the arm 24 of the floor joint plate push-up device 9 is pressed against the rear portion of the floor joint plate 7 by one housing 3 to rotate the push-up collar 23 in the guide tube 22. .

  The arm 24 moves upward along the inclined surface 19 of the notch 21 by the operation of rotating the push-up rod 23 of the arm 24. Therefore, the push-up rod 23 also moves upward while rotating, and the floor joint The rear part of the plate 7 is pushed upward.

  For this reason, when the joint portion becomes narrow due to the earthquake, the front end portion of the floor joint plate 7 is moved upward on the inclined surface 4, and the rear portion is pushed upward by the floor joint plate push-up device 9, and the floor joint plate 7 is tilted. It moves up and down in a substantially horizontal state without becoming a state.

  In order to move the floor joint plate 7 up and down in a substantially horizontal state, the arm 24 moves upward along the inclined surface 19 of the guide tube 22 by the inclination of the inclined surface 4 and the rotation of the arm 24. By setting the same amount, the floor joint plate 7 can be moved upward in a substantially horizontal state.

  At this time, the cover plates 12 and 12 at both ends of the floor joint plate 7 make the both ends become inclined surfaces 26 and 26, and can be used safely.

  When the shaking motion due to the earthquake stops, the lifting rod 23 and the arm 24 automatically return to the original state by the weight of the floor joint plate 7.

When the joint portion 2 becomes wide as shown in FIG. 9 due to the earthquake, the front end portion of the floor joint plate 7 slides on the joint plate slide support recess 5 to absorb the shaking motion.
In addition, when the shaking movement due to the earthquake stops, it automatically returns to the original state.
