[Means for Solving the Problems]

In the expansion joint device according to the present invention, edge members attached to the corners of the right and left skeletons facing each other with a gap of a predetermined gap and a cover horizontally provided on the upper surface of the skeleton so as to cover the gap. An expansion joint device including a plate; a metal slide plate slidably supporting both left and right end portions of the cover plate, is connected to an outer edge of the edge member, and An inner edge of a floor surface made of a finishing material such as an upper tile is connected to a parting edge having a slope inclined downward to the spacing side, and the sliding plate is attached to the parting edge. Connected so that it is lower than
Further, the cover plate is composed of a cover plate body made of a metal flat plate material, and an edging member fixed to the left and right edge portions of the cover plate body and having a tapered surface of a downward slope outward, The cover plate is arranged on the slide plate, and the upper surface of the cover plate is positioned on substantially the same horizontal plane as the floor surface.

[Action]

The cover plate is composed of a cover plate body made of a flat plate material made of metal, and an edging material fixed to the left and right edge portions of the cover plate body and having a taper surface that is inclined downward toward the outside. As the thickness of the sheet decreases, the strength of the left and right ends increases. Since the cover plate is arranged on the slide plate and the upper surface of the cover plate is located on substantially the same horizontal plane as the floor surface, the cover plate does not project above the floor surface. Further, since the parting edge has an inclined surface that is downwardly sloped toward the space portion side of the body and the edging material of the cover plate has a tapered surface that is downwardly sloped outward, it is difficult for the shoe tip or the like to be caught.

Reference numeral 32 is a water stop plate, which is composed of a strip-shaped sheet body having a predetermined width, and the left and right edges thereof are sandwiched by the metal sandwiching member 32, and attached to the holding piece portion 23 of the edge member 18 by screws 34. . 35
Is a bridging rod having a U-shaped cross section, and upwardly projecting engagement protrusions 36 are provided at the left and right ends. The protrusion 36 engages with the lower opening engagement groove 27 of the edge member 18. Also, the bridge bridge
A hole is provided through the center of the nut 35 and a nut 37 is fixed by welding or the like, or a screw hole is formed.

The cover plate 38 covers the entire space 16 with a width sufficiently larger than the predetermined space dimension L. The cover plate 38 is composed of a cover plate body 40 such as a stainless steel strip plate and an aluminum mold member or a plastic edging member 42 fixed to the left and right edge portions 40a with screws 41. That is,
The cover plate 38 includes a cover plate 40 made of a flat metal plate, and an edging member 42 fixed to the left and right edge portions 40a of the cover plate 40 and having a tapered surface 15 having a downward slope outward. , Consists of. A groove is formed on the lower surface side of the edging member 42, and a rubber or plastic elastic contact portion 46 is fitted into the groove. In FIG. 1, the edging material 42 has a screw mounting piece 43 that comes into contact with the back surface 45 of the cover plate body 40.
In addition to this, as shown in FIG. 2, it is also preferable that the screw mounting piece 43 contacts the upper surface of the cover plate 40. By doing so, a recess 44 having a depth corresponding to the thickness of the screw mounting piece 43 is formed on the upper surface of the cover plate 38,
A tile or striped stainless steel plate, carpet, or other surface material 60 can be applied to the recess 44. Also,
In that case, the gap dimension S between the cover plate 40 and the sliding plate 50 becomes extremely small, so that the gap size between the back surface 45 of the cover plate 40 and the upper horizontal piece 26 of the edge member 18 also becomes small. Therefore, the protrusion size of the packing 31 provided on the edge member 18 may be correspondingly reduced.

Then, returning to FIG. 1, the metal slide plate 50 slidably supporting the left and right ends of the cover plate 38 is used as an edge member.
A parting edge 53 having an inclined surface 14 having a downward slope toward the spacing 16 is connected to the outer edge of 18 and the inner edge of a floor surface 39 made of a finishing material such as a tile above the frame 17. While connecting

The gap dimension S between the cover plate 40 of the cover plate 38 and the slide plate 50 is set to be substantially the same as or smaller than the thickness dimension T of the cover plate 40 of the cover plate 38. The sliding plate 50 is made of a stainless steel strip plate, but other metals may be used. In addition, the parting edge 53 is made of extruded aluminum material, etc.
It is fixed at 20 via a connector 54.

At the center of the cover plate 38, a mounting hole 47 is formed in a plate-like shape, through which a bolt 48 is inserted, and a short tubular spacer.
The nut 37 (or the screw hole) of the bridging rod body 35 is screwed via 49. In the state immediately before this screwing, the left and right ends of the bridging rod 35 are placed on the horizontal abutting piece portions 22, 22 of the edge member 18, and the bridging rod 35 is engaged with the engaging concave groove 27 along with the screwing. The cover plate 38 can be fixed by engaging with the cover plates 27 and 27.

With the above configuration, the upper surface of the sliding plate 50 is the cover plate.
The elastic contact portions 46 at the left and right edge portions of 38 are slidably contact-supported. Then, the upper surface of the cover plate 38 is located on substantially the same horizontal plane as the floor surface 39, and the parting edge 53 and the edging material 42 are provided.
However, since each of them has the inclined surface 14 and the tapered surface 15, there is no fear that the person stumbles when the person passes over the cover plate 38.
Further, the cover plate body 40 of the cover plate 38 is made of a metal flat plate material, and the edging material 42 is fixed to the left and right edge portions 40a of the cover plate body 38. However, it does not bend or break. Further, the elastic contact portion 46 and the packing 31 prevent the cover plate 38 from vibrating in order to prevent the cover plate 38 such as water from flowing along the floor surface 39.
It is possible to prevent downward penetration. Further, since the predetermined spacing dimension L of the spacing portion 16 is sufficiently large, the left and right frames in the arrow C direction are
The relative movement of 17 can be dealt with by elastic bending deformation of the long bridge rod 35. In this way, the conventional coil spring is omitted in the vicinity of the bolt 48, and the structure is simple. The elastic contact portion 46 may be made of metal as long as it elastically contacts the sliding plate 50.

[Effect of device]

Since the present invention is configured as described above, it has the following effects.

The cover plate 38 does not project above the floor surface 39, and the inclined surface 14 of the parting edge 53 and the tapered surface 15 of the edging material 42 of the cover plate 38 make it difficult for the shoe tip to be caught. , It becomes difficult for a person to stumble over a foot when passing over the cover plate 38. Therefore, there is no danger of a person falling, and the safety is excellent.

The cover plate 38 includes a cover plate body 40 made of a flat plate material made of metal and edging members 4 fixed to the left and right edge portions 40a, 40a.
2, 42, the stainless steel plate or the like having a large wall thickness is used in view of strength and rigidity when the predetermined space dimension L of the space 16 is large. The difficult plate material can be used as it is without bending.
Therefore, the manufacture of the cover plate 38 is facilitated.
