Description

[Technical Field]

[0001] The present invention relates to a floor panel and a floor panel device that closes clearances between building frames. [Background technology]

[0002] Conventionally, as a floor panel device for closing the clearance between floor surfaces and a floor panel used in such a floor panel device, for example, a "floor panel including a shallow dish-shaped floor panel body and a filling member filled into this floor panel body" has been known, and many of these have been described in patent applications filed by the applicant in the past (for example, Patent Document 1, etc.). However, although the floor panel can close the clearance without any problems, if the clearance becomes narrow, the other end of the floor panel will rise upward using the part attached by the locking peg as a fulcrum, so it is necessary to create a gap between the first floor panel support part and one end of the floor panel large enough to allow the floor panel to rotate. However, there is a drawback in that dust can get into this gap. [Prior art documents] [Patent documents]

[Effects of the Invention]

[0012] As is clear from the above description, the present invention provides the following effects. (1) In each of the inventions described in claims 1 and 4, the side surface of one end of the floorboard body has a bending portion that bends toward one of the structural bodies, so that the floorboard can be rotated using this bending portion as a fulcrum. Therefore, the gap between the wall surface of the first floor panel support part and the side surface of one end of the floor panel can be made smaller than before without hindering the rotation of the floor panel. As a result, it is possible to minimize the intrusion of dust into the gap between the vertical wall surface of the first floor panel support part and the vertical outer wall surface of the mounting base end (one end) of the floor panel that faces this vertical wall surface. (2) By having the bent portion, when the filling material is filled, the upper side of the bent portion encases the filling material, improving the adhesion between the floor board body and the filling material, thereby preventing the floor board body and the filling material from peeling off. (3) The inventions described in claims 2 and 5 can also obtain the same effects as those described in (1) to (2), and by having a second bend portion, the adhesion between the floorboard body and the filling member can be further improved. (4) The inventions described in claims 3 and 6 can also achieve the same effects as those described in (1) to (3), and by forming a bent portion above the vertical center of the floor board body, the gap between the wall surface of the first floor board support portion and the side surface at one end of the floor board can be made smaller.

[0014] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to the accompanying drawings showing preferred embodiments of the present invention.

[0015] In a first embodiment of the present invention shown in FIGS. 1 to 7, reference numeral 1 denotes a floor panel device installed between one skeleton 3 and another skeleton 4 provided with a clearance 2 interposed therebetween.

[0016] The left-right direction refers to the left-right direction (longitudinal direction of the floorboard) in Figure 1 (plan view), the front-to-back direction refers to the up-down direction in Figure 1 (width direction of the floorboard, direction perpendicular to the longitudinal direction), and the up-down direction refers to the up-down direction in Figure 2 (thickness direction of the floorboard).

[0017] In addition, in this invention, a framework refers to a structure on which a floor plate can be installed, such as a building, road, slab, or elevator shaft, and an entrance / exit includes not only an entrance / exit with a door or a gate, but also a passageway through which people, vehicles, etc. can pass.

[0018] As shown in Figures 1 to 3, the floor panel device 1 of this embodiment is composed of a first floor panel support portion 5 provided on one of the bodies 3, a second floor panel support portion 6 provided on the other body 4, and a floor panel 7 of the present invention that is attached with one end supported by the first floor panel support portion 5 and the other end supported by the second floor panel support portion 6, and that blocks the clearance portion 2.

[0019] A first floor support portion 5 is formed on one of the bodies 3, and in this embodiment, as shown in Figure 2, this first floor support portion 5 is a recessed portion formed so as to extend in the front-to-rear direction on the floor surface on the clearance portion 2 side of one of the bodies 3, and is provided with locking pegs 9 that are inserted into peg cases 8 provided at both front and rear ends of one end of the floor panel 7 (described later). Note that the first floor support portion 5 may also be formed by fixing a metal member that is approximately angle-shaped or approximately crank-shaped to the wall surface on the clearance portion 2 side of one of the bodies 3.

[0020] A second floor support portion 6 is formed on the other frame 4, and this second floor support portion 6 is formed to a length that allows the floor 7 to slide left and right during an earthquake. In addition, at the end of the second floor support portion 6 opposite the clearance portion 2, a climbing inclined surface 10 is formed that the floor 7 can climb up on if the clearance portion 2 becomes narrower due to an earthquake.

[0021] 1, 2 and 3, the floor panels 7 of the present invention used in this floor panel device 1 are normally provided with a locking peg 9 provided on the first floor panel support part 5 inserted into a peg case 8 formed at the mounting base end (referred to as "one end" here), with one end supported in the mounted state and the other end supported directly or indirectly (via a support plate or the like) by the second floor panel support part 6, with a plurality of floor panels provided with almost no gaps in the front-to-rear direction of the clearance part 2. In FIG. 1, four floor panels 7 are provided, but this number is not limited thereto.

[0022] In this embodiment, as shown in Figures 4 and 5, the floorboard 7 comprises a shallow dish-shaped floorboard body 11, a filler member 12 such as mortar or concrete that is entirely filled inside the floorboard body 11, a decorative panel 13 made of marble tiles or bricks that is provided (e.g., attached) on the top surface of the filler member 12, pile cases 8 provided at both front-rear ends of one end of the floorboard body 11, a bending portion 14 provided on the outer surface of the one end corresponding to the base end of the floorboard body 11 and protruding so as to bend toward the one of the frames 3, and a vertically movable plate 16 attached to the other end of the floorboard body 11 via a hinge member 15. Note that the decorative panel 13 does not necessarily have to be installed in relation to the objectives of the present invention. The decorative panel 13 may be made of tiles, stone, or other plate-like materials. The bending portion 14 indicates that the outer surface of the one end is bent, and does not necessarily have to be bent to the inner wall surface of the floorboard body 14.

[0023] In addition, the floorboard main body 11 is a substantially rectangular parallelepiped member with an open top, and a pair of pile cases 8 into which locking piles 9 are inserted are provided at both ends inside one end (see FIG. 3). Furthermore, on the left and right side surfaces (side surfaces on one of the frame sides) of one end of the floorboard main body 11, bent portions 14 that are substantially V-shaped in cross section are formed (see FIG. 4). Note that the curvature, number, and shape of the V-shaped bent portions 14 in the embodiment can be arbitrarily modified in design as long as the object of the invention can be achieved.

[0024] The apex of the bent portion 14 is desirably formed at the center in the up-down direction of the floor panel main body 11 or above the center, and in this embodiment, it is formed so that the apex is located at a position 7 / 10 of the height of the floor panel main body 11. The height of this bent portion 14 in the left-right direction should preferably be about half the dimension of the gap that occurs when installing a conventional floor panel.

[0025] For example, in this embodiment, a floor panel body 11 having a width in the front-to-back direction of 600 to 800 mm, a length in the left-to-right direction of 1200 to 2000 mm, and a height of 80 to 120 mm is used, the length in the left-to-right direction to the apex of the bent portion 14 is approximately 2 mm, and the position in the left-to-right direction of the apex of the bent portion 14 is 7 / 10 of the height of the floor panel body 11 (if the height is 100 mm, it is 70 mm from the bottom surface of the floor panel body 11).

[0026] By forming the bent portion 14 in this manner, when the floor panel 7 is installed in the clearance portion 2, the apex of the bent portion 14 is brought into approximate contact with the wall surface 5a of the first floor panel support portion 5, thereby making it possible to reduce the gap between the wall surface 5a of the first floor panel support portion 5 compared to conventional floor panels and to prevent the rotation of the floor panel from being hindered when the clearance portion becomes narrow.

[0027] Furthermore, by providing such a bending portion 14 on the shallow dish-shaped floor panel body 11, the inner wall surface of the floor panel body 11 also bends in the same manner, so that when the filling member 12 is filled, it wraps around the filling member 12, such as mortar or concrete, thereby improving the adhesion and close contact between the filling member 12 and the floor panel body 11.

[0028] When an earthquake causes the main bodies 3 and 4 to sway left and right and the clearance section 2 to narrow, the floor panel device 1 of the present invention absorbs the shaking caused by the earthquake by having the floor panel 7 climb up the climbing slope 10 of the second floor panel support section 6, as shown in Figure 6.

[0029] When an earthquake causes the main bodies 3 and 4 to sway left and right and the clearance section 2 to widen, the floor panel device 1 of the present invention absorbs the shaking caused by the earthquake by causing the floor panel 7 to slide left and right on the second floor panel support section 6, as shown in Figure 7.

[0030] [Different modes for carrying out the invention] Next, different embodiments for carrying out the present invention will be described with reference to Figures 8 to 11. In describing these different embodiments for carrying out the present invention, the same components as those in the first embodiment for carrying out the present invention will be designated by the same reference numerals, and redundant description will be omitted.

[0031] The second form for carrying out the present invention shown in Figures 8 to 11 mainly differs from the first form for carrying out the present invention in that the second form uses a floor panel 7A that uses a floor panel main body 11A that has a second bending portion 17 on the side of the other end that bends toward the other body, and the floor panel device 1A that uses this floor panel; even with such a floor panel 7A or floor panel device 1A, the same effects as those of the first form for carrying out the present invention can be obtained.
