Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention covers joints generated between adjacent floors, and is particularly suitable for places where there are many pedestrians and durability is required. The present invention relates to a joint cover device.

[Prior Art] As a conventional joint cover device, there is known a joint cover device to which a stretchable synthetic resin cover is applied in order to absorb relative movement between adjacent floors. By the way, there was a defect that such a configuration was inferior in strength and weather resistance.

As the simplest structure, there is also a structure in which one cover plate is fixed to the floor on only one side and the other end is inserted into the floor on the other side, but this structure maintains a predetermined strength. Therefore, a sufficient overlapping width is required, and it is necessary to make the entire width considerably larger than the space between joints, and it is difficult to harmonize with the surrounding environment,
In addition, there is a drawback that it is slippery because it is a single metal plate.

An object of the present invention is to provide a joint cover device which is excellent in durability and does not have the above-described problems.

[Means for Solving the Problems] According to the present invention, a support case is arranged on both sides of the joint of both floors adjacent to each other via a joint, and ends of the bottom plate are inserted into both support cases. While supporting the bottom plate slidably to the left and right, a plurality of divided frames provided with a partial shielding plate covering the joint at the upper end on the bottom plate, the upper end of which is overlapped with adjacent partial shielding plates. By mounting, the joints are covered with a plurality of partial shielding plates, and a shaft rod is inserted through a vertically long hole penetrating the base of each divided frame, and the shaft rod is inserted between the divided frames. The present invention is characterized in that a spring is provided for urging the divided frames in the separating direction.

[Operation] When the floors move relative to each other in the left-right direction (floor separation direction), the front-back direction, or the up-down direction, the divided frames are not connected to each other, so that the divided frames move. At this time, since the partial shielding plates are overlapped with each other, they relatively move while closing the joint.

Embodiment An embodiment of the present invention will be described with reference to the accompanying drawings.

In FIGS. 1 and 2, floors x, x are adjacent via a joint s. The joint s is provided with the joint cover device 1 according to the present invention, and shields the joint s.

 The joint cover device 1 will be described in detail.

On the bases at the ends of the floors x, x, support cases 2, 2 are fixed, respectively. The supporting casings 2, 2 comprise a fixed frame 3 having a substantially L-shaped cross section and a substantially L-shaped border frame 4 connected to a horizontal mounting portion 3a formed at the upper end of the upper portion of the fixed frame 3. The rise of the
The horizontal portion of the border frame 4 blocks the inflow of the mortar m at the time of construction as described later, and creates a working space therein. The border frame 4 has a rising portion 4a at the inner end thereof joined to the inner surface of the joint s, and the joint s is bordered at the upper end.

At the inner end of the fixed frame 3 is a supporting ridge that rises slightly upward.
3b is extended, and the end of the bottom plate 10 inserted into the working space of the support housings 2, 2 is supported by the support projection 3b. Further, the inside of the border frame 4 is extended below the horizontal portion, and
An elongated hole 4c is formed in 4b, and the lower end of the extension 4b is mounted on the bottom plate 10. Thus, both ends of the bottom plate 10 are vertically held in line contact with the support projection 3b and the lower end of the extension portion 4b, and the bottom plate 10 is tiltably inserted into the joint s.

A fixing portion to which an end of a water blocking plate 7 made of a flexible rubber plate is fitted is provided outside the fixed frame 3.
Is blocking the joint s.

On the bottom plate 10, divided frames 11, 12 having a substantially horizontal H-shaped cross section and a T-shaped cross section are alternately mounted. The divided frame 11
The upper end is a partial shielding plate 11a, the lower part is a vertical riding foot plate 11b, and a vertical slot 11c is formed at the lower part of the vertical part, and on both sides and the center part in the figure. Three are arranged.

The divided frame 12 is formed by connecting an upper partial shielding plate 12a and a vertical mounting foot plate 12b via a rotation connection mechanism 12d including a substantially circular concave portion and a convex portion.
2d allows the partial shielding plate 12a to be tiltable. A long hole 12c in the vertical direction is formed in a lower portion of the mounting foot plate 12b. The two divided frames 12 are applied between the divided frames 11, and both ends of the partial shielding plate 12a at the upper end thereof are in contact with both ends of the partial shielding plate 11a of the divided frame 11 in a superposed manner from below. . Other configurations of the rotary connection mechanism 12d include various shapes such as a hinge having a substantially circular convex portion formed on the partial shielding plate 12a and a substantially circular concave portion formed on the upper end of the mounting foot plate 12b. Can be applied.

A shaft rod 14 is inserted into each of the elongated holes 11c and 12c of the divided frames 11 and 12, and both ends of the shaft rod 14 are inserted into the elongated holes 4c of the edging frame 4.

The shaft 14 is provided with a spike 15 between the divided frames 11 and 12 to urge the divided frames 11 and 12 in the separating direction to prevent the divided frames 11 and 12 from rattling.

With this configuration, the partial shielding plate 1 of each of the divided frames 11 and 12 is formed.
An joint cover 20 for shielding the joint s is constituted by 1a and 12a.

In this assembled state, the upper surface of the partial shielding plate 12a is placed on the floor.
If the construction is made flush with the floor surface of x, x, the degree of protrusion of the joint cover 20 from the floor surface is set to zero.

After such assembling, mortar m is driven onto floors x, x. At this time, the inside of the support housings 2, 2 is shut off, the inflow of the mortar m is prevented, and the working space is secured in the support housings 2, 2, so that the relative movement of the bottom plate 10 and the shaft 14 is allowed. You. Then, the finishing material n is further laid on the mortar m.

In the above configuration, when the floors x and x move relative to each other in the vertical direction as shown in FIG.
Tilting within 12c. Further, the divided frames 11, 12 move up and down with the inclination of the bottom plate 10, and the partial shielding plate 1 of the divided frame 12 is moved.
2a is tilted with respect to the mounting foot plate 12b by the rotation connection mechanism 12d. For this reason, the state where both ends of the partial shielding plate 12a are in contact with both ends of the partial shielding plate 11a in an overlapping manner is maintained, and no gap is formed in the joint cover 20.

Further, when the floors x, x move in the left-right direction (separation direction) with respect to each other, the partial shielding plate 11a and the partial shielding plate 12a slide to absorb the movement. FIG. 2 shows the maximum allowable proximity position of the floors x, x.

Furthermore, even when moving in the front-back direction, the partial shielding plate
11a and the partial shielding plate 12a relatively move in the front-rear direction, and the shaft 14 inclines in each of the long holes 11c, 12c to allow the relative movement.

In the above embodiment, the partial shielding plate 12a and the riding foot plate 12b
Is made rotatable by the rotation connection mechanism 12d, but the divided frame 12 may be formed by integrating the partial shielding plate 12a and the mounting foot plate 12b. Even in this case, the floor
There is no loss of followability to the relative movement of x, x.
In this configuration, a minute gap may be generated between the partial shielding plates 11a and 12a in accordance with the occurrence of the vertical displacement of the floors x and x.

[Effects of the Invention] Since the joint cover device 1 of the present invention has a plurality of divided frames 11, 12 mounted on the bottom plate 10, the joints s are covered by the partial shielding plates 11a, 12a. B) Even if the floors x, x move relative to each other left and right, up and down, and back and forth, they are absorbed by the relative movement of the divided frame 11 and the divided frame 12, so that the joint s can be shielded without any trouble.

B) The partial cover plates 11a and 12a can form the joint cover 20 having a width substantially equal to the width of the joint s.
20 widening can be prevented.

C) Even if the rider steps on the floor, the load is applied to the bottom plate 10 spread over the floors x, x, and therefore, it can sufficiently withstand heavy loads.

D) A non-slip effect is also exerted by a minute step generated between the partial shielding plates 11a and 12a.

And other excellent effects.
