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 when there is a difference in height between left and right floor frames and vehicles can pass through has been described as "a joint plate support recess formed on the joint side of the higher floor frame of left and right floor frames installed on a sloped road surface via a joint, a joint plate slide support recess formed on the inclined surface on the opposite joint side formed on the joint side of the lower floor frame of the left and right floor frames, on which the tip of the joint plate is supported, both sides of the rear end of the joint plate are supported in the joint plate support recess by pins so that the tip can rotate in the vertical direction, and the tip is supported in the joint plate slide support recess and covers the joint plate slide support recess, and the tip is connected to the tip of this joint plate via a hinge member. A joint device for sloped road surfaces is characterized by comprising a cover plate that is attached so as to be rotatable in the vertical direction, and a height-adjustable support base that is attached to the bottom surface near the tip of the joint plate and that can prevent rattling even when a load is applied to the end of the joint plate when the height of the left and right floor structures changes due to subsidence, etc. In this case, the support base is composed of a wedge-shaped support base body that is thicker at the rear end side than at the tip side of the joint plate, and an attachment member that is formed integrally with this support base body and has a long bolt insertion hole that is bolted to the bottom surface of the joint plate so that the support base body can slide toward the tip of the joint plate (Patent Document 1) and other documents are known.

[0003] However, although such joint devices for inclined road surfaces can prevent the joint plate from wobbling, when a vehicle or the like passes over, a left-right load is generated that moves the joint plate toward the other side of the structure, and since the device is unable to withstand this load, the left-right load is applied to the pins and locking piles that attach the joint plate, which could cause the locking piles to be damaged.

[0004] [Patent Document 1] Patent No. 4907474 Summary of the Invention [Problem to be solved by the invention]

[0005] In view of the above-mentioned drawbacks of the conventional method, the present invention aims to provide a floor joint device that can prevent a large load from being placed on the retaining piles even when large vehicles pass through, and that can smoothly absorb shaking caused by earthquakes.

[0006] The above and other objects and novel features of the present invention will become more fully apparent from the following description read in conjunction with the accompanying drawings.

[0007] However, the drawings are for illustrative purposes only and do not limit the technical scope of the present invention. [Means for solving the problem]

[0008] In order to achieve the above object, the floor joint device of the present invention described in claim 1 is a floor joint device for closing a joint between two frames when the floor surface of one frame is lower than the floor surface of the other frame, and the floor joint device comprises a first joint plate support part provided on the one frame, a second joint plate support part provided on the other frame so as to face the first joint plate support part and the joint part, and a first end side of the first joint plate support part. and a joint plate that is attached in an engaged state to a locking pile provided on the first joint plate support portion and has the other end supported on the second joint plate support portion, and a load-receiving mechanism that receives the left-right load applied to the joint plate while a vehicle is passing, wherein the load-receiving mechanism is characterized in that it is composed of an engaging member provided at the bottom of one end side of the joint plate and an engaged member that is provided on the wall surface of one of the bodies and is constantly engaged with the engaging member.

[0009] The second joint plate support part of the floor joint device described in claim 2 has an end opposite to the joint part formed with a sloped surface onto which the other end of the joint plate climbs during an earthquake, and the engaging part of the engaging member and the engaged part of the engaged member bear the load in the other body direction that is applied to the joint plate during vehicle passage, and are formed in a shape that does not hinder the other end of the joint plate from climbing up when it climbs up during an earthquake.

[0010] The floor joint device according to claim 3 is characterized in that the engaged portion is formed in a recessed shape, while the engaging portion corresponding to the engaged portion is formed in a convex shape. [Effects of the Invention]

[0011] As is clear from the above description, the present invention provides the following effects. (1) In the invention described in claim 1, a load-receiving mechanism is provided, which can receive the left-right load (especially the load on the joint plate in the direction of the other body) that occurs when a large vehicle or the like passes by. In addition, as shown in Figure 6, for example, when the wheels of a large vehicle such as a 10-ton or 20-ton vehicle ride on plate 8 and a load is applied to the plate in the direction indicated by the arrow, the engaging member on one side and the engaged member on the other side always function to prevent displacement, and a force acts to lift the engaged member from the engaging member, thereby preventing the load from being applied to the locking pile as much as possible. (2) Since no support base or the like is provided on the other end side of the joint plate, the other end side of the joint plate can smoothly slide over the second joint plate support part during an earthquake, and the shaking caused by the earthquake can be smoothly absorbed. (3) The invention described in claim 2 also provides the same effects as those described in (1) to (2) above, and since the engaging portion and the engaged portion are formed in a shape that does not hinder the other end of the joint plate from rising upward when an earthquake occurs, it can more smoothly absorb the shaking caused by an earthquake. (4) The invention described in claim 3 also provides the same effects as those described in (1) and (2) above, and since the engaged portion is formed in an approximately semicircular groove and the engaging portion is formed in an approximately semicircular shape, even if the position of the joint plate shifts left and right when the joint plate is raised, the engaging portion and the engaged portion act as guides for each other once the shaking caused by the earthquake has ended, and the joint plate can be automatically and reliably returned to its normal position.

DETAILED DESCRIPTION OF THE INVENTION

[0013] 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.

[0014] In the first form for implementing the present invention shown in Figures 1 to 8, 1 is a floor joint device installed between one body 3 provided via a joint portion 2 and the other body 4 whose floor surface is formed at a position lower than the floor surface of the one body 3.

[0015] In other words, when comparing the height of the floor surface of one body 3 with the height of the floor surface of the other body 4, the floor surface of the other body 4 is lower than that of the one body 3, and this is a floor joint device 1 that closes the joint 2 between the bodies 3 and 4.

[0016] The left-right direction refers to the left-right direction in Figure 1 (plan view) (the longitudinal direction of the joint plate 8), the front-to-back direction refers to the up-down direction in Figure 1 (the direction perpendicular to the left-right direction, the width direction of the joint plate 8), and the up-down direction refers to the up-down direction in Figure 2 (the thickness direction of the joint plate 8).

[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 an entrance / exit includes not only an entrance / exit with a door or a gate, but also a passageway through which people, vehicles 21, etc. can pass.

[0018] As shown in Figures 1 and 2, the floor joint device 1 of this embodiment is composed of a first joint plate support portion 5 provided on one of the frames 3, a second joint plate support portion 6 provided on the other frame 4 so as to face the first joint plate support portion 5 and the joint portion 2 therebetween, a joint plate 8 supported at one end by the first joint plate support portion 5 and attached in an engaging state to a locking pile 7 provided on the first joint plate support portion 5, and having the other end supported by the second joint plate support portion 6, and a load-receiving mechanism 9 that receives the left-right load applied to the joint plate 8 while a vehicle 21 is passing (in particular, the load applied to the joint plate 8 in the direction of the other frame).

[0019] A first joint plate support portion 5 is formed on one of the skeletons 3. In this embodiment, as shown in Figure 3, 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 this first joint plate support portion 5 is provided with a locking pile 7 that is inserted into a pile case 10 provided on the joint plate 8.

[0020] Further, on the wall surface 3a below the first joint plate support portion 5, an engaged member 11 of a load receiving mechanism 9, which will be described later, is provided.

[0021] The other skeleton 4 has a floor surface formed at a position lower than the floor surface of the one skeleton 3. A second joint plate support portion 6 is formed on the floor surface of this other skeleton 4 so as to face the first joint plate support portion 5 with the joint portion 2 interposed therebetween.

[0022] This second joint plate support part 6 is formed to a length that allows the joint plate 8 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 12 is formed that the joint plate 8 can climb up on if the joint part 2 narrows due to an earthquake.

[0023] In this embodiment, a climbing inclined surface 12 is formed as described above, but it is also possible to form a second joint plate support portion 6 that is approximately flat with the floor surface of the other body 4 without forming a climbing inclined surface 12.

[0024] As shown in Figure 4, the joint plate 8 is composed of a joint plate body 13 made of metal and formed into a shallow dish shape that is approximately rectangular in plan view, pile cases 10 provided on both sides of one end of the joint plate body 13, a filling member 14 such as mortar or concrete filled inside the joint plate body 13, a decorative panel 15 such as marble tile or brick attached to the top surface of the filling member 14, and a cover plate 17 attached to the other end of the joint plate body 13 via a hinge member 16.

[0025] Furthermore, an engaging member 18 of a load receiving mechanism 9, which will be described later, is provided at the bottom of one end of this joint plate 8.

[0026] Under normal circumstances, as shown in Figures 1 and 2, for example, one end of this joint plate 8 is supported by a locking pile 7 provided on the first joint plate support part 5, which is inserted into a pile case (e.g., rectangular in plan view) 10 formed at one end, and the other end is supported directly or indirectly (via a support plate, etc.) by the second joint plate support part 6 in the installed state, with one or more joint plates 8 being provided in the vertical direction of the joint part 2 (based on Figure 1).

[0027] In this embodiment, a plurality of joint plates 8 are received, and adjacent joint plates 8 are arranged with almost no gaps in the front-to-rear direction, with a gap of about 2 mm between adjacent joint plates 8. Incidentally, "almost no gaps" does not only mean that adjacent joint plates 8 are arranged in abutting contact, but also includes cases where they are arranged with a slight gap of about several millimeters.

[0028] In this embodiment, a shallow dish-shaped joint plate body 13 is used, and a filling material 14 is filled inside this joint plate body 13 and a decorative plate 15 is provided, but it is also possible to use a joint plate 8 that uses a plate-shaped (solid) joint plate body 13, or a joint plate 8 that does not have a decorative plate 15 or a cover plate 17, etc.

[0029] Furthermore, although the drawings show an example in which the lid of the pile case 10 is exposed on the surface of the joint plate 8, the pile case 10 may also be configured so that the joint plate 8 is not exposed (almost the entire surface is covered with decorative paneling).

[0030] As shown in Figure 5, the load-receiving mechanism 9 is provided at the bottom of one end of the joint plate 8 and is composed of an engaging member 18 having an engaging portion 19, and an engaged member 11 provided on the wall surface 3a of one of the bodies 3 and having an engaged portion 20 with which the engaging portion 19 of the engaging member 18 is always engaged, and is configured so that the engaging portion 19 and the engaged portion 20 engage when the joint plate 8 is installed.

[0031] Here, "always engaged" does not only mean a state in which the joints are engaged almost tightly under normal circumstances, but also includes a case in which this engagement state is momentarily released when the other end of the joint plate 8 rises up, but then the same engagement state as under normal circumstances is restored when the shaking caused by the earthquake ends.

[0032] The engaging portion 19 and the engaged portion 20 are capable of withstanding the left-right load applied to the joint plate 8 when a vehicle passes over it, and are formed in a shape that does not hinder the other end of the joint plate 8 from rising upward during an earthquake.

[0033] It is preferable that the engaged portion 20 is formed in a recessed shape, while the engaging portion 19 corresponding to the engaged portion 20 is formed in a convex shape, and more preferably, as in this embodiment, the engaged portion 20 is formed in a substantially semicircular groove, and the engaging portion 19 is formed in a substantially semicircular shape that engages with the engaged portion 20. In addition to this, the engaging portion 19 and the engaged portion 20 may be formed in an arc shape or an inclined surface shape on the other body side.

[0034] The engaging member 18 is a member whose tip (lower end) forms a substantially semicircular engaging portion 19, and in this embodiment, a pair is provided on the bottom surface of one end side of the joint plate 8 (joint plate main body 13). This engaging member 18 may be formed integrally with the joint plate main body 13, or may be fixed by welding or the like. Furthermore, in this embodiment, a pair is provided on the bottom surface of the joint plate 8, but one or three or more may be provided, and they may be provided so as to extend in the front-to-rear direction of the bottom of the joint plate 8.

[0035] The engaged member 11 is fixed to the wall surface 3a of one of the bodies 3 by anchor bolts or the like so as to correspond to the engaging member 18, and a groove-shaped engaged portion 20 is formed on the upper surface thereof.

[0036] Under normal circumstances, the engaging portion 19 and the engaged portion 20 are in an engaged state, and can bear a load in the left-right direction (direction parallel to the longitudinal direction of the joint plate 8).

[0037] Additionally, when a vehicle 21 or the like passes over, as shown in Figure 6, the rotation of the tire generates a force that pushes the upper surface of the joint plate 8 toward the other body 4, generating a load in the left-right direction (parallel to the longitudinal direction of the joint plate 8). However, this load can be received by the engaging portion 19 and the engaged portion 20 of the load-receiving mechanism 9, thereby preventing the load from being transmitted to the locking pile 7.

[0038] When an earthquake causes the frames 3 and 4 to shake left and right and the joint section 2 to narrow, the joint plate 8 climbs up the sloped climbing surface 12 of the second joint plate support section 6 to absorb the shaking caused by the earthquake, as shown in Figure 7. At this time, even if the joint plate 8 rises up while being displaced slightly left and right, once the shaking caused by the earthquake ends, the engaging section 19 and the engaged section 20 act as guides to correct the left and right misalignment of the joint plate 8, and it becomes engaged, automatically returning to its original state.

[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 8, the joint plate 8 slides left and right on the second joint plate support section 6, absorbing the shaking caused by the earthquake. [Industrial Applicability]
