[0016] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to the embodiments shown in the drawings.

[0017] In the first form for carrying out the present invention shown in Figures 1 to 12, reference numeral 1 denotes a floor joint device installed between one body 3 and another body 4 provided with a joint portion 2 interposed therebetween.

[0018] Note that the left-right direction refers to the left-right direction in Figure 1 (plan view) (the longitudinal direction of the floor joint plate), the front-back direction refers to the up-down direction in Figure 1 (the width direction of the floor joint plate, a direction perpendicular to the longitudinal direction), and the up-down direction refers to the up-down direction in Figure 2 (the thickness direction of the floor joint plate).

[0019] In addition, in the present invention, the term "structure" refers to a structure such as a building, road, slab, elevator shaft, etc. in which a joint plate can be installed, and an entrance / exit includes not only an entrance / exit with a door or gate, but also a passageway through which people, vehicles, etc. can pass.

[0020] As shown in Figures 1 to 3, the floor joint device 1 of this embodiment is composed of a first joint plate support part 5 provided on one of the structures 3, a second joint plate support part 6 formed on the other structure 4, and a floor joint plate 7 of the present invention which is attached with one end side supported by the first joint plate support part 5 and the other end side supported by the second joint plate support part 6, and which seals the joint part 2.

[0021] A first joint plate support portion 5 is formed on one of the skeletons 3, and in this embodiment, as shown in Fig. 2, this first joint plate support portion 5 is a recessed portion formed so as to extend in the front-to-rear direction on the floor surface on the joint portion 2 side of one of the skeletons 3, and is provided with a locking pile 9 to be inserted into a pile case 8 provided on both front and rear ends of one end of a floor joint plate 7 described later. Note that the first joint plate support portion 5 may be formed by fixing a metal member having a substantially angle or crank shape to the wall surface on the joint portion 2 side of one of the skeletons 3.

[0022] The other body 4 is formed with a second joint plate support part 6, which is formed to a length sufficient to allow the floor joint plate 7 to slide left and right during an earthquake. In addition, at the end of the second joint plate support part 6 opposite the joint part 2, a climbing inclined surface 10 is formed on which the floor joint plate 7 climbs up when the joint part 2 narrows due to an earthquake.

[0023] A plurality of floor joint plates 7 of the present invention used in this floor joint device 1 are provided, and normally, as shown in Figures 1 and 2, a locking pile 9 provided on the first joint plate support part 5 is inserted into a pile case 8 formed on one end, one end is supported in the attached state, and the other end is supported directly or indirectly (through a support plate or the like) by the second joint plate support part 6, and a plurality of floor joint plates 7 are provided with almost no gaps in the front-to-rear direction of the joint part 2. In Figure 1, four floor joint plates 7 are provided, but the number is not limited to this.

[0024] As shown in Figures 4 to 6, for example, this floor joint plate 7 is composed of a shallow dish-shaped joint plate main body 11, a reinforcing member 12 provided inside the joint plate main body 11, a plurality of fixing means 13 for fixing the reinforcing member to the joint plate main body 11, a filling member 14 such as mortar or concrete filled inside the joint plate main body 11, a decorative panel 15 such as a tile or brick made of marble or the like attached to the upper surface of the filling member 14, a pile case 8 provided at both ends in the front-to-rear direction on one end side of the joint plate main body 11, and a cover plate 17 attached to the other end side of the joint plate main body 11 via a hinge member 16.

[0025] The reinforcing member 12 is formed by combining a number of plate-like members 12a or bar members 12b in an approximately lattice pattern when viewed in a plane (see, for example, Figure 1). In this embodiment, it is composed of a number of plate-like members 12a extending in the longitudinal direction of the joint plate main body 11 and approximately round rod-shaped bar members 12b that are arranged approximately perpendicular to the plate-like members 12a and fixed by welding or the like to connect the multiple plate-like members 12a, and has a so-called grating-like shape (see Figures 3 and 5).

[0026] The fixing means 13 is composed of a number of bolts 18 fixed to the inner bottom surface of the joint plate main body 11 via a welding portion for connecting the joint plate main body formed at the end of the lower end, and a fixing device main body 19 attached to the bolts 18 and fixing the reinforcing member 12 (see, for example, Figures 3 and 6).

[0027] This bolt 18 is a bolt with no head, and in this embodiment, a so-called stud bolt is used, and a protruding welded portion 18a smaller than the diameter of the bolt 18 is formed at the lower end opposite the non-welded portion on the upper end side (see FIG. 3, for example), and this small protruding welded portion 18a is melted with a burner, electric current, etc. to fix the bolt 18 to the inside bottom surface of the joint plate main body 11. In addition, a small protruding welded portion 18a for joining to the joint plate main body is formed on the underside of the lower end of the bolt 18. Therefore, by melting the welded portion 18a formed at the lower end of the bolt 18 and fixing the bolt 18 to the bottom of the joint plate main body 11, it is possible to prevent heat sufficient to burn the material from being transferred to the bottom of the joint plate main body 11, and to prevent burn marks from being formed on the outer bottom of the joint plate main body 11 (the bottom surface of the joint plate main body 7).

[0028] Regarding the size, shape, and protrusion amount of the welded portion 18a, it is preferable that they are large enough to fix the bolt 18 and not leave a burn mark on the bottom of the joint plate 7 (the outer bottom of the joint plate main body 11) when melted.

[0029] The fixing device main body 19 is a metal fitting like a grating clip that is roughly M-shaped in cross section or roughly hat-shaped in cross section, and is arranged to span the upper ends of adjacent plate members 12a or bar members 12b, and is fixed to the joint plate main body 11 by pressing the plate members 12a or bar members 12b from above downward.

[0030] Specifically, this fixing device main body 19 is composed of engagement portions 19a provided on the left and right sides of the fixing device main body 19 and engaging with the upper end portion of the plate-like member 12a or bar member 12b, and a bolt through hole 19b provided in approximately the center of the fixing device main body 19. By passing a bolt 18 through this bolt through hole 19b and screwing a nut 18b into it, the plate-like member 12a or bar member 12b is pressed downward from above, and the reinforcing member 12 is fixed to the joint plate main body 11.

[0031] Meanwhile, the manufacturing method 20 of floor joint plates of the present invention for manufacturing such floor joint plates 7 includes a bolt fixing process 21 for fixing a large number of bolts 18 in parallel to the inner bottom surface inside the shallow dish-shaped joint plate main body 11, a reinforcing member arranging process 22 for arranging a lattice-shaped reinforcing member 12 as a whole inside the joint plate main body 11, a reinforcing member fixing process 23 for fixing the reinforcing member 12 with a plurality of fixing means 13, and a filling process 24 for filling the inside of the joint plate main body 11 with a filling member 14, as shown in Figures 7 to 10.

[0032] In the bolt fixing process 21, a small protruding welding portion 18a formed at the lower end of the bolt 18 for connecting to the joint plate body is melted by electric current or the like to fix (burn) the bolt 18 to the inside bottom surface of the joint plate body 11. Possible methods for melting and fixing by electric current or the like include resistance welding such as projection welding and spot welding. Note that while it is preferable to fix the bolt by such resistance welding, any method can be used as long as it can be welded to the base material of the joint plate body 11 without transmitting high heat that would cause the base material to deteriorate.

[0033] The reinforcing member placement process 22 is a process of placing the reinforcing member 12 inside the joint plate main body 11. In this embodiment, the reinforcing member placement process 22 is performed after the bolt fixing process 21, but the reinforcing member placement process 22 can also be performed first.

[0034] The reinforcing member fixing process 23 is a process in which the bolt 18 is inserted through the bolt hole 19b provided in approximately the center of the fixing device main body 19 and a nut is screwed in to press the plate-shaped member 12a or bar member 12b of the reinforcing member 12 from above downward (to the internal bottom surface of the joint plate main body 11), thereby fixing the reinforcing member 12 to the joint plate main body 11.

[0035] The filling process 24 is a process of filling the inside of the joint plate body 11 to which the reinforcing member 12 is fixed with a filling member 14 such as mortar or concrete. In this process, if necessary, a decorative panel 15 may be provided so as to be flat with the upper surface of the joint plate body 11.

[0036] In addition to these steps, a cover plate attachment step of providing the cover plate 17 may be performed separately.

[0037] When an earthquake causes the structural bodies 3, 4 to shake left and right and the joint portion 2 to narrow, in the floor joint device 1 of the present invention, as shown in Figure 11, the floor joint plate 7 climbs up the climbing inclined surface 10 of the second joint plate support portion 6 to absorb the shaking caused by the earthquake.

[0038] When an earthquake causes the main bodies 3, 4 to shake left and right and the joint portion 2 becomes wider, the floor joint device 1 of the present invention, as shown in Figure 12, causes the floor joint plate 7 to slide left and right on the second joint plate support portion 6, absorbing the shaking caused by the earthquake.

[0039] In the embodiment of the present invention, a reinforcing member having an approximately lattice shape when viewed from above is used, but the reinforcing member may also be made by fixing multiple plate-shaped members extending in the longitudinal direction of the floor joint plate, or the reinforcing member may be made by combining plate-shaped members in a honeycomb shape, etc. [Industrial Applicability]
