Abstract
Description
[Technical Field]
[0001] The present invention relates to a floor joint device that closes joints between building frames that are provided with joints in between. [Background technology]
[0002] Conventionally, a floor joint device for closing a joint between floor surfaces through which vehicles can pass has been described as "a joint plate slide support recess with an inclined surface formed on the floor surface of one of the floor frames on the joint side of the left and right floor frames provided through the joint, a floor joint plate whose tip is supported so as to cover this joint plate slide support recess and whose rear end is attached to the other floor frame via a fixture so that the tip can rotate upward, and a cover plate attached to the tip of this floor joint plate so that the tip can rotate up and down on the one floor frame, In a floor joint device consisting of the above, a cover plate support recess having an inclined surface on the opposite joint side, which is formed on the floor surface of one of the floor structures with which the tip of the cover plate abuts, so that the upper surface of the cover plate and the upper surface of one of the floor structures are flush with each other and can be supported without gaps, and a guide protrusion having an inclined surface on the joint side, which can guide the tip of the floor joint plate formed on the inclined surface side of the joint plate slide support recess upward by the thickness dimension of the cover plate (Patent Document 1) and the like are known.
[0003] However, because vehicle joint plates are required to be stronger than joint plates installed for pedestrian passage, they must be thicker than pedestrian joint plates. This creates the problem that if pedestrian and vehicle joint plates are installed next to each other in an area where pedestrian and vehicle passages are adjacent, the vehicle joint plate will end up being higher, creating a step-like shape.
[0004] Therefore, it has been difficult to install the walkways so as to eliminate the difference in level between the pedestrian and vehicle walkways, or to install the pedestrian walkways one step higher than the vehicle walkways to make it difficult for vehicles to enter.

[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 the first embodiment of the present invention shown in Figures 1 to 11, 1 is a floor joint device installed between one body 3 and the other body 4 provided with a joint portion 2 therebetween.
[0016] The left-right direction refers to the left-right direction in Figure 1 (plan view) (the longitudinal direction of the pedestrian joint plate 9), the front-to-back direction refers to the up-and-down direction in Figure 1 (the width direction of the pedestrian joint plate 9, a direction perpendicular to the longitudinal direction), and the up-and-down direction refers to the up-and-down direction in Figure 2 (the thickness direction of the pedestrian joint plate 9).
[0017] In addition, in this invention, the term "structure" refers to a structure such as a building, road, slab, elevator shaft, etc., on which a joint plate can be installed, and the term "entrance" refers not only to an entrance with a door or a gate, but also to a passageway through which people, vehicles, etc. can pass.
[0018] As shown in FIGS. 1 to 4, the floor joint device 1 of this embodiment comprises a first pedestrian joint plate support portion 5 provided on one of the skeletons 3, a first vehicle joint plate support portion 6 provided on the one of the skeletons 3 in a stepped shape adjacent to the first pedestrian joint plate support portion 5 and formed so that its upper surface is positioned lower than the first pedestrian joint plate support portion 5, a second pedestrian joint plate support portion 7 provided on the other of the skeletons 4 so as to face the first pedestrian joint plate support portion 5 across the joint portion 2, and a second pedestrian joint plate support portion 8 provided on the other of the skeletons 4 so as to face the first vehicle joint plate support portion 6 across the joint portion 2. The joint plate is made up of a second vehicle joint plate support portion 8 provided on the support structure, one or more pedestrian joint plates 9 attached with one end supported by the first pedestrian joint plate support portion 5 and the other end supported by the second pedestrian joint plate support portion 7, one or more vehicle joint plates 10 attached with one end supported by the first vehicle joint plate support portion 6 and the other end supported by the second vehicle joint plate support portion 8 and higher than the pedestrian joint plate 9, and a boundary joint plate 11 provided between the pedestrian joint plate 9 and the vehicle joint plate 10.
[0019] One of the frames 3 is formed with a first pedestrian joint plate support portion 5 and a first vehicle joint plate support portion 6, and as shown in Figure 2, the first pedestrian joint plate support portion 5 and the first vehicle joint plate support portion 6 are recessed portions formed in the floor surface on the joint portion 2 side of one of the frames 3 so as to extend in the front-to-rear direction, with a step formed between the first pedestrian joint plate support portion 5 and the first vehicle joint plate support portion 6. The first pedestrian joint plate support portion 5 and the first vehicle joint plate support portion 6 are provided with locking piles 13 that are inserted into pile cases 12 provided on a pedestrian joint plate 9, a vehicle joint plate 10, and a boundary joint plate 11, which will be described later.
[0020] The first vehicle joint plate support portion 6 is formed so that its upper surface is lower than the first pedestrian joint plate support portion 5. Specifically, the first and second vehicle joint plate support portions 6, 8 are formed so that when the vehicle joint plate 10 or boundary joint plate 11 is installed, the upper surface of the vehicle joint plate 10 is approximately flush with the upper surface of the boundary joint plate 11 or is lower than the upper surface of the boundary joint plate 11. In this embodiment, the first vehicle joint plate support portion 6 and the second vehicle joint plate support portion 8 are formed so that the upper surface of the vehicle joint plate 10 is lower than the upper surfaces of the pedestrian joint plate 9 and boundary joint plate 11.
[0021] In addition, a metal member having an approximately angle or crank shape may be fixed to the wall surface on the joint portion 2 side of one of the bodies 3 to serve as the first pedestrian joint plate support portion 5 and the first vehicle joint plate support portion 6.
[0022] On the other body 4, a second pedestrian joint plate support portion 7 is formed so as to face the first pedestrian joint plate support portion 5 via the joint portion 2, and a second vehicle joint plate support portion 8 is formed so as to face the first vehicle joint plate support portion 6 via the joint portion 2.
[0023] The second pedestrian joint plate support portion 7 and the second vehicle joint plate support portion 8 are formed to a length that allows the joint plates 9, 10, and 11 to slide left and right during an earthquake. In addition, the ends of the second pedestrian joint plate support portion 7 and the second vehicle joint plate support portion 8 opposite the joint portion 2 are formed with a climbing inclined surface 14 onto which the joint plates 9, 10, and 11 climb when the joint portion 2 narrows due to an earthquake.
[0024] Under normal circumstances, as shown in Figures 1 to 4, the pedestrian joint plate 9 is provided with one or more locking piles 13 attached to the first pedestrian joint plate support part 5 inserted into a pile case (e.g., square in plan view) 12 formed at one end, with one end supported in the installed state and the other end supported directly or indirectly (via a support plate, etc.) by the second pedestrian joint plate support part 7, in the vertical direction of the joint part 2 (based on Figure 1).
[0025] Furthermore, as shown in Figures 1 to 4, the vehicle joint plate 10 is a plate that is thicker than the pedestrian joint plate 9, and has a pile case (for example, square in plan view) 12 formed at one end into which a locking pile 13 provided on the first vehicle joint plate support part 6 is inserted, and one end is supported in the installed state, and the other end is supported directly or indirectly (via a support plate, etc.) by the second vehicle joint plate support part 8, and one or more of them are provided in the vertical direction of the joint part 2 (based on Figure 1).
[0026] As shown in Figures 1 to 4, the boundary joint plate 11 is a plate of approximately the same thickness as the pedestrian joint plate, and has a pile case (e.g., square in plan view) 12 formed at one end into which a locking pile 13 provided on the first pedestrian joint plate support part 5 is inserted, so that one end is supported in the installed state and is supported directly or indirectly by the first vehicle joint plate support part 6 by a support means 15 described later, and the other end is supported directly or indirectly (via a support plate, etc.) by the second pedestrian joint plate support part 7 and the second vehicle joint plate support part 8.
[0027] In this embodiment, adjacent joint plates 9, 10, 11 are arranged with almost no gaps in the front-to-rear direction, with a gap of about 2 mm between adjacent joint plates 9, 10, 11. By almost no gaps, it is not only meant that adjacent joint plates 9, 10, 11 are arranged in abutting contact with each other, but also includes cases where they are arranged with a slight gap of about several millimeters.
[0028] As shown in Figure 5, the pedestrian joint plate 9 is composed of a metal pedestrian joint plate body 16 that is approximately rectangular in plan view, the pile case 12 provided on both sides of one longitudinal end of the pedestrian joint plate body 16, a filling member 17 such as mortar or concrete filled inside the pedestrian joint plate body 16, a decorative panel 18 such as marble tile or brick attached to the top surface of the filling member 17, and a cover plate 20 attached to the other end side of the pedestrian joint plate body 16 via a hinge member 19.
[0029] As shown in Figure 6, the vehicle joint plate 10 is composed of a metal vehicle joint plate main body 21 that is approximately rectangular in plan view, the pile case 12 provided on both sides of one longitudinal end of the vehicle joint plate main body 21, a filling member 17 such as mortar or concrete filled inside the vehicle joint plate main body 21, a decorative panel 18 such as marble tile or brick attached to the top surface of the filling member 17, a cover plate 20 attached to the other end side of the vehicle joint plate main body 21 via a hinge member 19, a stepped support portion 23 extending in the left-right direction on the side facing the boundary joint plate 11, and a pin insertion hole 26 into which a mounting pin 25 fixed to a supported portion 24 supported by the support portion 23 is inserted.
[0030] As shown in Figures 7 and 8, the boundary joint plate 11 is composed of a metal boundary joint plate main body 22 that is approximately rectangular or square in plan view, a pair of pile cases 12 provided on the first pedestrian joint plate support part 5 side at one left-right end of the boundary joint plate main body 22, a filling member 17 such as mortar or concrete filled inside the boundary joint plate main body 22, a decorative panel 18 such as marble tile or brick attached to the top surface of the filling member 17, a cover plate 20 attached to the other end side of the boundary joint plate main body 22 via a hinge member 19, a notched supported part 24 that extends left-right on the lower part of the side facing the vehicle joint plate 10 and abuts in approximately surface contact with the top surface of the support part 23, and a plurality of mounting pins 25 provided on the supported part 24. The vehicle joint plate 10 and the boundary joint plate 11 are each provided with a support means 15 which is arranged so that the upper surface of the boundary joint plate 11 is approximately horizontal or approximately parallel to the upper surfaces of the other joint plates 9 and 10 when supported by the first and second vehicle joint plate support portions 6 and 8.
[0031] In this embodiment, this support means 15 is composed of a support portion 23 provided on the side of the vehicle joint plate 10 facing the boundary joint plate 11, a supported portion 24 provided on the bottom of the boundary joint plate 11 facing the vehicle joint plate 10 and supported by this support portion 23, a plurality of pin insertion holes 26 provided in the support portion, and an attachment pin 25 provided in the supported portion 24 and inserted into the pin insertion hole 26.
[0032] In this embodiment, the support portion 23 is provided by fixing a square pipe-shaped member to the side of the vehicle joint plate main body 21, but it may also be formed integrally with the vehicle joint plate main body 21, or the support portion 23 may be formed by fixing a solid bar-shaped (square column-shaped) member instead of a square pipe-shaped member.
[0033] In this embodiment, the supported portion 24 is formed in a notched recess provided in the side (bottom) of the boundary joint plate 11 facing the vehicle joint plate 10, but it does not necessarily have to be a notched recess and may be formed flat with the bottom of the boundary joint plate 11. Conversely, this portion may be formed in a downwardly convex shape.
[0034] Furthermore, in this embodiment, a plurality of pin insertion holes 26 and mounting pins 25 to be inserted into these pin insertion holes 26 are provided, but the vehicle joint plate may simply be provided with a support portion 23, and the supported portion 24 may be supported on the upper surface of this support portion 23, forming the support means 15. Furthermore, if the supported portion 24 is formed in a downwardly convex shape (similar to a sleeper-shaped support leg), the vehicle joint plate 10 may not be provided with a support portion 23, and the support means 15 may be directly supported by the first and second vehicle joint plate support portions 6, 8.
[0035] This support means 15 is provided in a position where, when an earthquake causes the left and right frames 3, 4 to sway in different forward and backward directions, it will not interfere with (clash with) the step between the second pedestrian joint plate support portion 7 and the second vehicle joint plate support portion 8. In order to install it in such a position, the front-to-back dimensions of the boundary joint plate 11 are formed to be such that it will not come off the pedestrian joint plate support portions 5, 7 due to the forward and backward shaking caused by an earthquake, and will be able to absorb the shaking caused by the earthquake.
[0036] In this embodiment, shallow dish-shaped joint plate bodies 16, 21, 22 are used, and the inside of these joint plate bodies 16, 21, 22 is filled with filling material 17 and a decorative plate 18 is provided.However, for example, joint plates 9, 10, 11 may be used that use plate-shaped (solid) joint plate bodies 16, 21, 22, or joint plates 9, 10, 11 that do not have a decorative plate 18 or cover plate 20, etc.
[0037] Furthermore, although the drawings show an example in which the cover of the pile case 12 is exposed on the surface of the joint plates 9, 10, and 11, the pile case 12 may also be configured so that the joint plates 9, 10, and 11 are not exposed (almost the entire surface is covered with decorative panels).
[0038] When an earthquake causes the main bodies 3 and 4 to sway left and right and the joint section 2 to narrow, as shown in Figure 9, the joint plates 9, 10, and 11 climb up the sloped surfaces 14 of the second joint plate support sections 7 and 8, absorbing the shaking caused by the earthquake.
[0039] When an earthquake causes the main bodies 3 and 4 to shake left and right and the joint section 2 to widen, as shown in Figure 10, the joint plates 9, 10, and 11 slide left and right on the second joint plate support sections 7 and 8, absorbing the shaking caused by the earthquake.
[0040] When an earthquake causes the structures 3 and 4 to sway in different forward and backward directions, as shown in Figure 11, the joint plates 9, 10, and 11 slide forward and backward on the second joint plate support parts 7 and 8, absorbing the shaking caused by the earthquake.
[0041] [Different modes for carrying out the invention] Next, different embodiments for carrying out the present invention will be described with reference to Figures 12 to 14. 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.
[0042] The second form for implementing the present invention shown in Figures 12 to 14 is mainly different from the first form for implementing the present invention in that the first and second vehicle joint plate support portions 6A, 8A are formed at a height such that the upper surfaces of the pedestrian joint plate 9, vehicle joint plate 10 and boundary joint plate 11 are approximately horizontal or parallel without any steps, and even with such a floor joint device 1A, the same effects as those of the first form for implementing the present invention can be obtained. [Industrial Applicability]
[0043] The present invention finds application in the floor jointing equipment manufacturing industry. [Explanation of symbols]
