Description

[Technical field]

[0001] The present invention relates to a joint plate that closes a joint between structural members provided through a joint, and a floor joint device that includes the joint plate. [Background technology]

[0002] Examples of joint plates and floor joint devices that close joints and have reinforcing members provided inside the joint plate include "a floor joint plate comprising a metal square shallow dish-shaped joint plate body, a plurality of reinforcing bar holders fixed at predetermined intervals in the front-to-rear direction to the inner bottom surface of the joint plate body by spot welding, the upper part of which is located within the joint plate body and has a channel-like or trapezoidal contour shape with an upper part that opens out, a plurality of reinforcing bar insertion grooves formed therein, and a plurality of reinforcing bar support parts formed therein, a plurality of reinforcing bars inserted into the plurality of reinforcing bar insertion grooves of the plurality of reinforcing bar holders, the plurality of reinforcing bars being located in the front-to-rear direction of the joint plate body and welded to the upper parts of the plurality of reinforcing bar support parts of the plurality of reinforcing bar holders, and concrete filled into the joint plate body so as to cover the plurality of reinforcing bar holders and the plurality of reinforcing bars" and "a floor joint device using such a joint plate" (Patent Document 1).

[0003] Although this type of joint plate has greater strength than a normal joint plate, when it is installed in an area where heavy objects such as vehicles pass through, a bending force is generated on the other end of the joint plate body when the vehicle directly rides on the cover plate or joint plate body, which could cause cracks in the filling material (mortar, etc.) between the reinforcing bar and the other end of the joint plate body.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0015] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to the embodiments shown in the drawings.

[0016] In a first embodiment for carrying out the present invention shown in Figures 1 to 7, reference numeral 1 denotes a floor joint device that is installed between one body 3 and another body 4 provided with a joint portion 2 interposed therebetween.

[0017] 1, the front-rear direction refers to the up-down direction in FIG. 1, and the up-down direction refers to the up-down direction in FIG.

[0018] 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 the term "entrance / exit" refers not only to an entrance / exit with a door or gate, but also to a passageway through which people, vehicles, etc. can pass.

[0019] This floor joint device 1, as shown in Figures 1 and 2, is composed of a first joint plate support part 5 provided on one of the structures 3, a second joint plate support part 6 provided on the other structure 4, and a joint plate 7 having one end supported by the first joint plate support part 5 and the other end supported by the second joint plate support part 6.

[0020] This first joint plate support part 5 is a recessed portion formed in the floor surface on the joint part 2 side of one of the bodies 3, and a locking pile 8 is fixed to the first joint plate support part 5. This locking pile 8 supports one end side of the joint plate 7 when inserted into a pile case 9 provided on the joint plate 7.

[0021] A recessed second joint plate support portion 6 is formed on the floor surface on the joint portion 2 side of the other body 4, allowing the other end of the joint plate 7 to slide left and right, and a climbing inclined surface 10 is formed on the end of this second joint plate support portion 6 opposite the joint portion 2, over which the other end of the joint plate 7 can climb if the joint portion 2 narrows due to an earthquake.

[0022] The joint plate 7 of the present invention used in this floor joint device 1 is, as shown in Figures 3 to 5, composed of, for example, a shallow dish-shaped joint plate body 11, a pair of pile cases 9 provided on one end side of the joint plate body 11 and into which the upper end side of the locking pile 8 is inserted, a plurality of bar-shaped reinforcing members 12 provided inside the joint plate body 11 and extending in the left-right direction, a filling member 13 such as cement or mortar filled in the joint plate body 11, a connecting means 14 connecting the end of the reinforcing member 12 to at least one of the inner wall surfaces on one end side or the other end side of the joint plate body 11, a decorative plate 15 provided to cover the upper part of the filling member 13, and a cover plate 17 provided on one end and the other end of the joint plate body 11 via a hinge member 16. In this embodiment, the connecting means 14 connects the inner wall surface on the other end side of the joint plate body 11 to the end of the reinforcing member 12.

[0023] A plurality of reinforcing members 12, for example bar-shaped or plate-shaped, are fixed inside the joint plate body 11, and both longitudinal ends of the reinforcing members are provided with a slight gap between them and the inner surfaces of one end side and the other end side of the joint plate body 11. Crosspieces 18 connecting the plurality of reinforcing members 12 are provided on the other end side of the reinforcing members (the end side to which the cover plate 17 of the joint plate body 11 is attached).

[0024] In this embodiment, the crosspieces 18 are plate-shaped members to which the ends of the reinforcing member 12 are connected by welding or the like, but multiple crosspieces may also be provided in the middle portion of the reinforcing member 12, forming an approximately lattice-like shape when viewed in a plane.

[0025] The reinforcing member 12 and the crosspiece 18 are formed to a height sufficient to be buried when the filling member 13 is filled into the joint plate body 11 .

[0026] As shown in Figure 5, the connection means 14 is composed of a plurality of one-side connection members 19 fixed to the reinforcing member 12 or the crosspiece 18, and the other-side connection members 20 provided on at least one of the inner wall surfaces on one end side or the other end side of the joint plate main body 11 and connected to the one-side connection members 19, respectively.

[0027] One connecting member 19, in this embodiment, is provided in plurality at a predetermined interval in the front-to-rear direction and is fixed to crosspiece 18 by bolts, welding, or the like, and is composed of a first connecting fitting 21 having a substantially angle shape fixed to the inside of crosspiece 18, a second connecting fitting 22 having a substantially angle shape fixed to the outside of crosspiece 18, and through holes 23 provided in each of first connecting fitting 21 and second connecting fitting 22. This through hole 23 is provided so as to be substantially coaxial when first connecting fitting 21 and second connecting fitting 22 are fixed to crosspiece 18.

[0028] The other connecting member 20 is provided in plurality at a predetermined interval in the front-to-rear direction on the inner surface of the left-right end of the joint plate body 11 so as to face one connecting member 19, and is composed of a substantially angle-shaped connecting member body 24 and a through hole 25 formed in this connecting member body 24, and is attached so that this through hole 25 is substantially coaxial with the through hole 23 of one connecting member 19. In this embodiment, the other connecting member 20 is attached to the joint plate body 11 using a bolt 26 for attaching the hinge member 16.

[0029] The one connecting member 19 and the other connecting member 20 are integrally connected to each other via a connector. In this embodiment, both connecting members 19, 20 are connected by a tapping screw 27, bolt, or pin that passes through the through hole 25 and the through hole 23. When using a tapping screw, the through hole 25 and the through hole 23 are formed as small holes, and the tapping screw 27 is passed through the through hole 25 and the through hole 23 to fix them.

[0030] Therefore, the multiple reinforcing members 12 have their ends connected by crosspieces 18, and the connection means 14 is composed of a multiple number of one-side connecting members 19 fixed to the reinforcing members 12 or the crosspieces 18, and the other-side connecting members 20 provided on at least one of the inner wall surfaces of the joint plate main body 11 at one end side or the other end side, connected to the one-side connecting members 19 and also connected to the inner wall surface of the joint plate main body 11, and the one-side connecting members 19 and the other-side connecting members 20 are integrally connected via tapping screws 27.

[0031] By connecting the reinforcing member 12 and the joint plate main body 11 using the connecting means 14 in this manner, the rigidity of the joint plate main body 11 is improved, and deformation can be prevented even when subjected to bending stress, thereby preventing damage to the filling member 13, etc.

[0032] In this embodiment, only the other end side of the joint plate body 11 is connected to the reinforcing member 12 by the connecting means 14, but one end side may also be connected using the connecting means 14 in the same manner.

[0033] When the left and right structural members 3, 4 shake left and right during an earthquake and the joint 2 narrows, as shown in Figure 6, the other end of the joint plate 7 rides up onto the slope 10 and rises upward to absorb the shaking caused by the earthquake.

[0034] When an earthquake causes the main bodies 3 and 4 to shake left and right and the joint section 2 becomes wider, as shown in Figure 7, the other end side of the joint plate 7 slides left and right along the upper surface of the second joint plate support section 6, absorbing the shaking caused by the earthquake.

[0035] In the present invention, the reinforcing member 12 and the end of the joint plate main body 11 are connected by a connecting means 14, so that even if a vehicle is placed on the cover plate 17 in this state, the joint plate main body 11, filling member 13, etc. can absorb the shaking caused by an earthquake without being damaged.

[0036] [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 duplicated descriptions will be omitted.

[0037] In the second form for carrying out the present invention shown in Figures 8 to 11, the main difference from the first form for carrying out the present invention is that the joint plate 7A is provided with cover plates 17 on one end side and the other end side, and the inner surface of the joint plate main body 11 on one end side and the inner surface of the reinforcing member 12 on both ends are connected by connecting means 14, and a first joint plate support part 5A is formed with a riding inclined surface 10, and a central maintenance device 28 (approximately pantograph-shaped in this embodiment) using a pantograph shape or rack and pinion, etc. is provided between one body and the other body, and this central maintenance device 28 is connected to the joint plate 7A to form a floor joint device 1A in which the approximate center of the joint plate 7A is always positioned approximately in the approximate center of the joint part 2. Even with such a joint plate 7A or floor joint device 1A, the same effects as those of the first embodiment can be obtained.

[0038] In the embodiment of the present invention, the connection means is described as connecting the inner surface of one end side and the other end side of the joint plate body to the reinforcing member, but it is also possible to provide a means for connecting the inner surface of the joint plate body in the front-rear direction to the reinforcing member. By using the connection means for connecting the inner surface of the joint plate body in the front-rear direction to the reinforcing member in this way, the rigidity of the joint plate can be further increased.

[0039] In addition, in the embodiment of the present invention, a connecting member having a first connecting fitting and a second connecting fitting is used, but it may also be possible to connect using, for example, only either the first connecting fitting or the second connecting fitting.

[0040] Furthermore, in the embodiment of the present invention, the one connecting member and the other connecting member are formed into a substantially angled shape, but any shape may be used as long as it can connect the reinforcing member and the joint plate body. [Industrial Applicability]
