Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention covers joints generated between adjacent floors, and follows relative displacement between floors in the left-right direction, front-back direction, and up-down direction. The present invention relates to a floor joint cover device that is capable of withstanding heavy loads.

[Prior Art] As a conventional floor joint cover device, in order to absorb relative movement between adjacent floors, one cover plate is fixed to the floor on one side only, and the other end is attached to the floor on the other side. There is a structure to pass. However, in this structure, since the edge of the cover plate is connected and fixed to one of the floors, the relative movement of the floor in the vertical direction causes the cover plate to be curved or having a gap, resulting in poor tracking performance.

In addition, this structure requires a sufficient overlapping width between the edge of the joint cover plate and the floor surface in order to maintain a predetermined function, and it becomes necessary to make the overall width wider than the joint interval.

Further, when a heavy vehicle such as a forklift passes over the joint, the cover device cannot bear the load and is destroyed.

On the other hand, as a means for correcting this drawback, the front portion is provided with a comb-shaped linking portion formed by alternately arranging a plurality of linking fingers in the left-right direction and finger gaps into which the linking finger pieces can be inserted. The cover member is composed of the left and right cover plates, and a retractable filling member is arranged between the tip of the linking finger piece and the base of the finger gap to enable lateral movement of the cover plates and the finger gap is provided by the filling member. A structure in which no voids are formed is disclosed in Japanese Utility Model Publication No. 60-165511.

This is capable of absorbing relative movement of the floor, and does not cause bending or the like even when a heavy load is applied from above due to the rigidity of the cover plate, and is suitable for a passage.

[Problems to be solved by the present invention] By the way, in the conventional configuration including the above-mentioned comb-shaped linking portion, since the base portion of the cover plate is directly fixed to the floor, relative movement in the vertical direction of the floor is prevented. In order to make it possible, it is necessary to create a working space between the tip of the linking finger and the finger gap, and a supplementary member is provided so that the working space can be shielded without impairing the movement of the linking finger. ing. That is, in such a configuration, if the supplementary member is not provided,
This may interfere with walking and dust may fall into the joints.

Since the supplementary member is provided in the working space in this way,
Only within the range of the expansion and contraction characteristics of the supplementary member, the cover plate can be moved in the right and left directions, and there is a limit to the following performance. Further, since a material such as synthetic rubber or plastic is applied to this supplementary member, there is a problem in durability on a road exposed to wind and rain, and it is necessary to replace it appropriately. Furthermore, the relative movement of the cover plate in the longitudinal direction along the longitudinal direction cannot be followed because the base of the cover plate is fixed to the floor.

An object of the present invention is to provide a floor joint cover device having a structure capable of withstanding a heavy load and having excellent follow-up performance and durability.

[Means for Solving the Problems] The present invention is to fix a fixed body, which is fixed to the left and right floors adjacent to each other via joints, by projecting a support special note upward, and to be engaged with the support projection after the main plate portion. A locking projection is provided that is restrained from moving inwardly with respect to the body, and a plurality of link fingers in the left-right direction and finger gaps allowing insertion of the link fingers are alternately arranged in front of the main plate portion. With a comb-shaped linking part
A sliding groove surface having a thickness substantially equal to the thickness of the main plate portion is formed on the upper surface of the linking finger piece, and the linking finger pieces are inserted into the finger gaps,
The left and right cover plates are mounted on the other fixed body so that the tips of the linking finger pieces go under the main plate portion of the cover plate.

[Operation] In the cover plates on both sides, the expanded-diameter linking finger pieces are inserted into the finger gaps of the other cover plate, and the front end portions thereof are inserted under the main plate portion and the end portions thereof are inserted into the other side. Place on a fixed body. That is, the main plate portions of the other cover plate overlap on the sliding groove surface. Therefore, the finger gap is blocked by the linking finger piece,
Therefore, no void is generated. When the floors move relative to each other in the left-right direction, the cover plate has its rear end supported by the support projection of one fixed body by engaging the locking projection edge, so that the finger of the other cover plate is supported. The linking finger piece moves within the gap, and the tip thereof slides with respect to the other fixed body to absorb this movement. Further, when the floors move in the vertical direction, each cover plate can be tilted because it is not connected to the other cover plate, and therefore the moving component is absorbed by the tilt. Furthermore, when the floors move in the front-rear direction, each cover plate is restrained from moving to the left and right by the supporting projections with respect to the fixed body.
The cover plate is movable with respect to the fixed body and thus absorbs its moving component.

Furthermore, when a large load is applied to the cover plate, each cover plate is hung on the left and right fixed bodies and supported at both ends, so that the cover plate is made of a rigid material, Sufficient strength can be achieved.

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

In FIG. 1, floors f and f are adjacent to each other through a joint s. The joint s for the floor according to the present invention is attached to the joint s to block the joint s. The joint cover device 1 will be described in detail.

Fixed bodies 2 are fixed by anchor bolts 8 on the bases at the ends of the floors f. The fixed body 2 has a substantially L-shaped cross section, and defines a mortar m to be driven into the periphery by a rising wall 4 connected to the outer end of the fixed body 2. A support projection 5 is formed just inside the rising wall 4, and a fitting groove 6 is formed between the rising wall 4 and the support projection 5. The upper surface, which is further inside than the support protrusion 5, is used as a slide support surface 7.

Reference numerals 10 and 10 denote left and right cover plates mounted on the fixed bodies 2 and 2.

The cover plates 10, 10 are provided with a locking projection 12 which is fitted into the fitting groove 6 at the rear edge of the main plate 11 and engages with the support projection 5 to restrain the inward movement. Further, the front portion of the main plate portion 11 is provided with a comb-shaped linking portion 16 formed by a plurality of linking finger pieces 14 protruding from each other through a finger gap 15 into which the linking finger pieces 14 can be inserted. A mounting edge 18 projects downward from the tip of the linking finger piece 14.
On the other hand, as shown in FIGS. 2 and 3, a plurality of reinforcing ribs 17 are provided from the lower surface to the rear portion of each linking finger piece 14 to maintain its strength.
Is rushed.

A sliding groove surface 19 having the same thickness as the main plate portion 11 is formed on the upper surface of the linking finger piece 14. Furthermore, the cover plate 10,1
An end plate 20 having a connection hole 21 is vertically provided on one side surface of the rear part of the rear part 0, and a connection pin 22 to be inserted into the connection hole 21 is provided at the base of the outermost reinforcing rib 17 on the other side. ing.

In the cover plates 10, 10 having such a configuration, the finger gaps 15 at the rear portions are fitted into the fitting grooves 6 of the one fixed body 2, and the linking finger pieces 14 are inserted into the finger gaps 15 mutually. , The link finger
Insert the front end of 14 into the lower part of the main plate 11. At this time, the linking finger piece 14 is smoothly inserted into the main plate portion 11 by the sliding groove surface 19 on the upper surface thereof, and the riding edge 18 at the tip thereof is mounted on the sliding support surface 7 of the other fixed body 2. And each fixed body 2,
It is arranged between two. Therefore, the finger gap 15 does not cause an opening.

On the other hand, the cover plates 10, 10 adjacent to each other in the front-rear direction are connected by inserting the connecting pin 22 into the connecting hole 21 on both side surfaces of the rear part.

Then, in this state, the joint s between the floors f and f is the cover plates 10 and 1
Shielded by 0.

In such a configuration, when the floors f, f relatively move in the left-right direction, as shown by the arrow in FIG.
For 0, the rear end is locked to the indicator protrusion 5 of the one fixed body 2
2 is engaged and is supported by the upper edge of the locking protruding edge 12, the linking finger piece 14 moves within the finger gap 15 of the other cover plate 10, and the riding edge 18 at the tip thereof is moved. It slides on the sliding support surface 7 of the other fixed body 2, and its moving component is absorbed. In the approaching direction, the follow-up performance in the left-right direction is possible until the base edge 19a of the sliding groove surface 19 contacts the base edge of the finger gap 15.
In the separating direction, it is possible until the riding edge 18 is separated from the sliding support surface 7. Therefore, a relatively wide movement allowance can be achieved.

Further, when the floors move in the vertical direction, the mounting edges 18 of the respective cover plates 10 and 10 are only supported by the other cover plate 10, and can be tilted because they are not connected,
The moving component is absorbed by the inclination. Furthermore, when the floors f, f move in the front-back direction, each fixed body 2, 2
The cover plates 10 and 10 are relatively movable in the front-rear direction, and the cover plates 10 and 10 slide on the fixed bodies 2 and 2 to absorb the moving component. When the floor joints 1 move the floors f, f in the left-right, up-down, front-back three-dimensional directions, the floor joints are absorbed to cover the joints s.

Further, in this floor joint cover device 1, when a large load is applied from above, the rigidity of each cover plate 10, 10 is secured by the reinforcing ribs 17, and the fixed bodies 2, 2 on both sides are secured. Since both ends are supported by, it is possible to achieve sufficient strength, and therefore, it is possible to withstand even a forklift or the like riding.

Furthermore, each cover plate 10, 10 adjacent in the front-rear direction,
Since the connecting pin 22 is inserted into the connecting hole 21 and connected in the vertical direction, the cover plates 10 and 10 do not jump up due to an impact or the like from above.

With the above-described structure, various shapes of patterns can be formed on the upper surfaces of the cover plates 10, 10.

[Advantage of the Invention] In the joint cover device 1 of the present invention, the rear ends of the cover plates 10 and 10 are connected to the fixed bodies 2 and 2 only in the left-right direction, and the comb-shaped linking portion 16 formed in the front part thereof. , 16 are meshed with each other, and further, the sliding groove surface 19 formed on the upper surface of the linking finger piece 14 to be inserted into the finger gap 15 causes the tip end of the linking finger piece 14 to the other cover plate.
