Description

  The present invention relates to a joint device for a floor that can absorb a shaking movement without exceeding a boundary line even in a place where there is not a sufficient dimension to the boundary line, even when a large shaking movement occurs during an earthquake.

Conventionally, when the left and right floor frames are swung so that the joints are widened by an earthquake, the floor joint device that supports the joint plate support mechanism using the joint plate that projects the lower part of the joint plate into the joints is the joint plate. When the operating rod of the support mechanism protrudes and the tip of the joint plate is supported near the protruding tip, the joint plate is sufficiently supported if the engagement dimension with the support cylinder at the rear end of the working rod is small In other words, if the engagement dimensions of the support cylinder and the actuating rod are set so that the joint plate can be supported sufficiently, there is a disadvantage that a large swaying movement cannot be absorbed.

The lower end portion on the joint portion side fixed to the support tube 6 or the one floor casing 5 is positioned in the joint portion direction so as to be positioned on the support mechanism 8 and the support tube 6 of the joint plate support mechanism 8. The fixed joint plate 10 formed on the protruding inclined surface 9 and the one floor The other part which has the protrusion part 11 which protrudes only by the width dimension 4 of the said joint part 3 located through the body 5 and the said joint part 3, and becomes the upper surface position substantially the same as the upper surface position of the said fixed joint plate 10 A rear end portion is attached to the floor casing 12 and the projection 11 on the joint section side of the other floor casing 12 so as to be movable upward, a front end portion is supported by the joint plate support mechanism 8, and the fixed joint plate The joint plate 14 formed on the inclined surface 13 that can be moved upward by the ten inclined surfaces 9, and one end portion that regulates the protruding position of the operating rod 7 of the joint plate support mechanism 8 are at the tip of the operating rod 7. A stopper 15 using a chain, rope, or wire attached to the joint 5 side of the one housing 5 and the other end projecting downward from the tip of the operating rod 7 of the joint plate support mechanism 8. support A support body 17 having a rear end portion fixed to the joint portion side of the one floor casing 5 at a position where a front end portion that supports the slidable movement 16 can enter a lower portion of the projecting portion 11 of the other floor casing 12; It consists of

  The joint plate support mechanism 8 is fixed to the upper surface of the one floor casing 5 at a predetermined interval, and has a plurality of width dimensions of the one floor casing 5, and a tip portion slightly protrudes from the joint section 3. A rectangular cylinder or the like, a rectangular operating rod 7 that slides inside the supporting cylinder 6 and protrudes from the tip portion to the joint portion 3, and these operating rods 7 always protrude to the joint portion 3. The biasing springs 18 are respectively housed in the plurality of support cylinders 6 to be biased.

  The fixed joint plate 10 is positioned on the upper part of the support cylinder 6 of the joint plate support mechanism 8 fixed to the upper part of the one floor casing 5 so that the tip part does not protrude from the tip part of the support cylinder 6. It is fixed to the support cylinder 6 or the one floor casing 5.

  The joint plate 14 is formed on the inclined surface 13 with a rear end supported by a cylindrical support member 20 fixed to the projecting portion 11 on the joint portion side of the other floor frame 12 by a plurality of tapping screws 19. The joint plate main body 21 supported by the tip end portion of the support cylinder 6 through a slight gap, and the rear end portion of the joint plate main body 21 is in contact with the inclined surface 9 of the fixed joint plate 10. An engagement pin that is attached to a portion corresponding to the support member 20 on the bottom surface of the joint plate and slides while being supported by the support member 20 even if the tip end portion of the joint plate main body 21 rotates upward. 22.

  The support rod 16 is composed of a support arm 23 that protrudes downward from the distal end portion of the operating rod 7 and a roller 24 that is attached to the distal end portion of the support arm 23 and slides on the support body 17. Yes.

  The support 17 has a T-shaped projection 11 that protrudes by the width dimension 4 of the joint 3 and is formed in a T-shape, and the tip is gradually reduced in size. ing.

  As shown in FIG. 2, the floor joint device 1 having the above-described configuration normally has the joint portion 3 covered with the fixed joint plate 10 and the joint plate 14 having the same upper surface as the upper surface of the fixed joint plate 10. It has become.

  At this time, the joint plate 14 is supported at the rear end portion by the support member 20 fixed to the projecting portion 11 on the joint portion side of the other floor frame 12, and the tip portion is supported by the plurality of support cylinders 6 of the joint plate support mechanism 8. It is in a state supported by.

  For this reason, it can drive | work on the joint plate 14 safely.

  When the joint portion 3 becomes wider as shown in FIG. 6 due to the earthquake, the other floor housing 12 is separated from the one floor housing 5, and the tip portion of the joint plate 14 moves integrally with the other floor housing 12. Slidably moves on the support cylinders 6 and the operating rod 7 of the joint plate support mechanism 8 to absorb the shaking motion.

  At this time, the load of the joint plate 14 is applied to the plurality of operating rods 7 of the joint plate support mechanism 8, but the rear end portions of the plurality of operating rods 7 are supported by the plurality of support cylinders 6, and the tip portions are Since both ends are supported by the support rod 16 that is slidably supported by the support 17, the tip end portion of the joint plate 14 is safely supported without sinking. .

  When the joint portion 3 becomes narrow as shown in FIG. 7 due to the earthquake, the other floor housing 12 approaches the one floor housing 5, and the inclined surface 9 of the fixed joint plate 10 causes the inclined surface of the tip portion of the joint plate 14. 13 is abutted and pushed up so that the joint plate 14 rides on the fixed joint plate 10, and when the ride increases, the rear end of the joint plate 14 moves upward due to the weight of the joint plate 14 and becomes horizontal. .

  In addition, since the width dimension of one floor frame 5 and the width dimension 4 of the joint part 3 are substantially the same dimension, even if it moves to the maximum, the front-end | tip part of the joint plate 14 does not exceed the boundary line 2. FIG.

  Moreover, since the front-end | tip part of the support body 17 penetrates into the lower part of the protrusion part 11 of the other floor frame 12, it is not damaged.

When the shaking motion in the earthquake stops, it automatically returns to the original state.
[Different forms for carrying out the invention]
Next, different modes for carrying out the present invention shown in FIGS. 8 to 13 will be described. In the description of the different embodiments for carrying out the present invention, the same components as those in the first embodiment for carrying out the present invention are denoted by the same reference numerals, and redundant description is omitted.
