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 whose rear end is supported by the support recess 6 and whose tip is supported by the joint plate slide support recess 5 is covered with the floor joint plate 7 and the rear joint of the floor joint plate 7 is connected to the floor. The tip of the joint plate 7 can be rotated upward The fitting 8 attached to the joint plate supporting 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 is along the inclined surface 4. The floor joint plate push-up device 9 pushes up the rear part upward.

  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 formed by forming a support recess 18a in the other casing 3 at a lower position of the rear center part of the floor joint plate 7, and a lower end on the support base 18. A shaft 19 with a fixed portion, a cylindrical push-up rod 20 that can rotate on the shaft 19 and slide upward to push up the rear portion of the floor joint plate 7, and the push-up rod 20 One end is fixed to the push-up mechanism 21 that is pushed upward when it rotates, and the other end is in contact with the joint-side portion of the one housing 3 at an angle smaller than a right angle. When the portion 2 is narrowed, it is constituted by an arm 22 that rotates the push-up bar 20 and pushes it upward.

  The push-up mechanism 21 is configured by using an inclined surface 23 at the top fixed to the support base 18 in the vicinity of the shaft 19, an arm for rotating the push-up mechanism 20, or a guide piece 24 that contacts the inclined surface 23. ing.

  Since the arm 22 is fixed when the lifting rod 20 is pressed by the weight of the floor joint plate 7, the arm 22 is brought into contact with one housing 3 so that the angle is smaller than a right angle in this state. It is set so that the arm 22 can be reliably rotated when the joint portion 2 becomes narrow.

  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. The arm 22 of the floor joint plate push-up device 9 is pressed by one housing 3 at the rear part of the floor joint plate 7, and rotates around the cylindrical push-up tack 20. .

  By this rotation, the arm 22 is moved upward by the inclined surface 23 of the guide piece 24, pushes up the push rod 20, and pushes up the rear part of the floor joint plate 7.

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

  In order to move the floor joint plate 7 up and down in a substantially horizontal state, the arm 22 moves upward along the inclined surface 23 of the guide piece 24 by the inclination of the inclined surface 4 and the rotation of the arm 24. By setting the movement amount to be the same, 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 25 and 25, and can be used safely.

  When the shaking motion due to the earthquake stops, the lifting rod 20 and the arm 22 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.
