Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a floor joint cover device for covering joints generated between adjacent floors.

[Prior Art] As a conventional joint cover device, there is known a joint cover device to which a stretchable cover made of a synthetic resin material is applied in order to absorb relative movement between adjacent floors. A general configuration of this kind will be described with reference to FIG.

L-shaped fixing frames a and a are arranged on both sides of the joints s of both floors f and f that are adjacent to each other through the joints s. Is supported so as to be slidable from side to side and passed over, and an elastic cover c made of synthetic resin is mounted on the bottom plate b. On the other hand, one end of the floor plate d is supported on the upper edges of the fixed frames a, and the other end is locked to one end of the elastic cover c, and thus the central elastic cover c and the both sides of the elastic cover c are secured. Floorboard d,
The d forms a cover that covers the joint s.

[Problems to be Solved by the Invention] By the way, in the conventional configuration, the floor plate d is formed of a plate material such as metal or synthetic resin, and the material is directly exposed in a pure state. Therefore, if a floor finishing material such as a tile is laid on the surrounding floor surface, there is a drawback that it does not match the surrounding environment. An object of the present invention is to provide a joint cover device having a structure that can match the surrounding floor surface.

[Means for Solving the Problem] The present invention is arranged on both sides of floors that are adjacent to each other through a joint, at a side position of the joint, and a support projecting edge that extends slightly upward is formed at the inner end. On the outer edge, there is a fixed frame that projects upward from the rising edge, and rectangular base parts are formed at both ends.There is a groove that opens upward between the rectangular base parts. A bottom plate that is slidably supported in the left-right direction, a stretchable cover that has locking grooves formed at both ends, and is mounted on the upper surface of the rectangular base, and both of the rectangular base of the bottom plate. A linking piece that is fixed along the side surface and has a locking protrusion that fits the lower edge into the locking groove on the inner end side of the elastic cover at the outer end, and the outer end is fixed to the upper ends of the rising portions of both fixing frames. , A hanging portion projecting downwardly from the inner end of the elastic cover is fitted in the locking groove on the outer end side of the elastic cover, and the edging frames are arranged on both sides of the elastic cover. It is characterized in that filled with flooring in the bottom two coordinated formed in the groove in the pieces on the board.

[Operation] In the above-mentioned configuration, rectangular base parts are provided on both sides of the bottom plate slidably supported on the fixed frames arranged on both sides of the joint, and the elastic covers are arranged on the base parts. In addition, a linking piece is provided on each inner surface of the rectangular base, and the linking piece holds the inner end of the stretchable cover to form a groove between the linking pieces on the bottom plate. Then, the floor finishing material is filled in the groove to be in harmony with the surrounding environment.

In such a configuration, when the floors move relative to each other in the left-right direction (the floor separating direction), the front-rear direction, or the up-down direction, the bottom plate is linked to the respective fixed frames through the elastic covers. Moves relative to the fixed frame by expanding and contracting.

Therefore, even if the floors relatively move in each direction, the joint s can be shielded while absorbing the plastic deformation without causing the members to plastically deform.

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

In FIGS. 1 and 2, the floors f and f are adjacent to each other through the joint s. A joint cover device 1 according to the present invention is attached between the joints s to shield the joints s.

 The joint cover device 1 will be described in detail.

Pre-deep grooves 30, 30 on the bases on both ends of the floor f
Is formed in advance, the mortar 31 for level adjustment is filled into the fixed portion 30, and the fixed frames 2 and 2 having a substantially L-shaped cross section are sandwiched on the upper surface of the mortar 31 so as to sandwich the end portion of the water blocking plate 22 made of a flexible rubber plate. Mount and bolt 3
Fixed by 2. A rising portion 2a is formed at the outer end of the fixed frame 2, and the ridge rising portion 2a blocks the inflow of the mortar 20 at the time of construction, as will be described later, and creates a working space therein. . Further, the outer ends of the U-shaped edging frames 4 and 4 are fixed to the upper ends of the rising portions 2a of the fixing frames 2 and 2 by screws 5 and 5, respectively. The borders 4, 4 border the joint s on the upper surface thereof.

A support projection 3 is formed on the inner end of the fixed frame 2 so as to rise slightly upward, and the end of the bottom plate 10 inserted into the working space of the fixed frames 2 and 2 is supported by the support projection 3. are doing.

Explaining the configuration of the bottom plate 10, the rectangular base portions 11, 11 are formed at both ends thereof, and a groove 12 is formed between the rectangular base portions 11, 11, and the upper surfaces of the rectangular base portions 11, 11 are formed. Elastic cover 15,
There are 15 mounting surfaces 13. The elastic covers 15 and 15 are
It is made of synthetic resin material and has locking grooves on both ends.
16a and 16b are formed, and T-shaped locking projections are formed on the mounting surfaces 13 and 13 of the linking pieces 17 and 17 fixed by screws 19 along both inner side surfaces of the concave groove 12. Lower groove of 18,18 locking groove 16a, 1
By fitting into the 6a, the inner ends of the elastic covers 15 and 15 are connected to the bottom plate 10 side.

Further, the hanging portions 4a at the inner ends of the edging frames 4, 4 are fitted in the locking grooves 16b, 16b.

Thus, the fixed frames 2, 2, the edging frames 4, 4, the stretchable covers 15, 15 and the bottom plate 10 are connected.

In this way, the fixed frame 2, 2 is attached to the edging frame 4, the elastic covers 15, 15.
After assembling, etc., mortar 2 around the fixed frame 2, 2.
Type 0 and then tile 21. At this time, the above-mentioned groove 12 is also filled with mortar 22, and the same tile 23 as the tile 21 is laid so that the surrounding floor surface and the inside of the groove 12 have a similar appearance.

This completes the construction, the edging frame 4, the elastic covers 15,1
The joint s is shielded by the 5 and the tile 23.

In such a configuration, when the floors f, f move relative to each other in the left-right direction (floor separating direction), the front-back direction, or the vertical direction,
Since the bottom plate 10 is linked to the fixed frames 2 and 2 via the elastic covers 15 and 15, the bottom plate 10 can be moved by the expansion and contraction of the covers 15 and 15. For this reason, even if the floors f, f relatively move in each direction, the joint s can be shielded while absorbing the relative displacement without causing plastic deformation of each member of the joint cover device 1.

[Advantage of the Invention] As described above, the present invention provides the rectangular base portions 11 and 11 on both sides of the bottom plate 10 slidably supported on the fixed frames 2 and 2 arranged on both sides of the joint, respectively. The elastic covers 15 and 15 are arranged on the pedestal part, and the linking pieces 17 and 17 are provided on the inner side surfaces of the rectangular pedestal parts 11 and 11, respectively. By holding the inner end, both linking pieces on the bottom plate 10
A groove 12 is formed between 17,17,
The recessed groove 12 can be formed without difficulty in assembling, and a floor surface similar to the surrounding floor surface can be formed in the recessed groove 12, which can be adapted to the mounting environment and can be stretched on both sides of the recessed groove 12. cover
15, 15 can be arranged, the concave groove 12 can be positioned in the center of the joint without unevenness, and an excellent effect can be provided such that a planar shape excellent in design can be provided.
