Description

Technical Field

[0001] The present invention relates to a floor joint device for closing a joint between bodies provided via a joint portion.

Background Art

[0002] Conventionally, as a floor joint device for closing a joint between floor surfaces when there is a height difference between left and right bodies and vehicles can also pass through, there is "a joint plate support recess formed on the joint side of the higher floor body of the left and right floor bodies provided via a joint portion on a road surface having a gradient, and the anti-joint side formed on the joint side of the lower floor body of the left and right floor bodies is an inclined surface, and a joint plate slide support recess formed on an inclined surface where the tip of the joint plate is supported, and both side portions of the rear end are supported by pins in the joint plate support recess so that the tip can rotate in the vertical direction, the tip is supported by the joint plate slide support recess, a joint plate covering the joint plate slide support recess, a cover plate whose tip is rotatably attached in the vertical direction via a hinge member to the tip of this joint plate, and when the height of the left and right floor bodies changes due to subsidence or the like near the bottom surface of the tip of the joint plate, a support base capable of height adjustment that can prevent rattling even when a load is applied to the end of the joint plate. In the joint device for a gradient road surface characterized by comprising: a wedge-shaped support base body whose rear end side is thicker than the tip side of the joint plate; and a mounting member integrally formed with this support base body, having a long-hole-shaped bolt insertion hole formed on the bottom surface of the joint plate so that the support base body can slide in the direction of the tip of the joint plate and is bolt-fixed." (Patent Document 1) etc. are known.

[0003] However, in such a joint device for a gradient road surface, although rattling of the joint plate can be prevented, when a vehicle or the like passes through, a lateral load that moves the joint plate to the other body side occurs, and since this load cannot be received, there is a risk that the lateral load is applied to the pin or locking pile for attaching the joint plate, and the locking pile or the like may be damaged.

[0004] [Patent Document 1] Patent No. 4907474 [Overview of the project] [Problems that the invention aims to solve]

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

[0006] The aforementioned and other objectives and novel features of the present invention will become more fully apparent when the following description is 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] To achieve the above objective, the floor joint device of the present invention described in claim 1 is a floor joint device for sealing a joint between structural bodies when, comparing the heights of the floor surface of one structural body and the floor surface of the other structural body, the floor surface of the other structural body is lower than that of the one structural body, and comprises: a first joint plate support portion provided on the one structural body; a second joint plate support portion provided on the other structural body so as to face the first joint plate support portion and the joint portion; and one end of the first joint plate support portion supported The joint plate is attached in a locked state to a locking pile provided on the first joint plate support portion, and its other end is supported on the second joint plate support portion, and the joint plate is equipped with a load receiving mechanism that receives lateral loads applied to the joint plate when a vehicle passes over it, wherein the load receiving mechanism is equipped with an engaging member provided on the bottom of one end of the joint plate and an engaged member provided on the wall surface of one of the structures and constantly engaged with the engaging member.

[0009] The floor joint device according to claim 2 is characterized in that the end of the second joint plate support portion opposite to the joint portion has a ride-up inclined surface formed on which the other end of the joint plate rides up during an earthquake, and the engaging portion of the engaging member and the engaged portion of the engaged member are formed in such a shape that they receive the load applied to the joint plate in the other direction of the building structure during the passage of a vehicle, and do not hinder the upward movement of the other end of the joint plate when it rises upward during an earthquake.

[0010] The floor joint device described in claim 3 is characterized in that the engaged portion is formed in a concave 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 explanation, the present invention provides the following effects. (1) In the invention described in claim 1, a load-receiving mechanism is provided, so that the load in the left-right direction (especially the load in the other direction of the structure applied to the joint plate) that occurs when large vehicles pass by can be received by this load-receiving mechanism. 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 are on the 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 work to prevent them from shifting at all times, and a force acts to lift the engaged member away from the engaging member, so that the load applied to the locking pile can be prevented as much as possible. (2) Since no support base or the like is provided on the other end of the joint plate, the other end of the joint plate can slide smoothly against the second joint plate support during an earthquake, and the shaking caused by the earthquake can be absorbed smoothly. (3) In the invention described in claim 2, the same effects as in (1) and (2) above can be obtained, and the engaging portion and the engaged portion are formed in a shape that does not obstruct the upward movement of the other end of the joint plate when it rises upward during an earthquake, so that the shaking caused by the earthquake can be absorbed more smoothly. (4) In the invention described in claim 3, the same effects as in (1) to (2) above can be obtained, and since the engaged portion is formed in a substantially semicircular groove and the engaging portion is formed in a substantially semicircular shape, even if the position of the joint plate shifts in the left-right direction when the joint plate rises up, once the shaking caused by the earthquake stops, the engaging portion and the engaged portion act as guides for each other, and the joint plate can be automatically and reliably returned to its normal position.

Mode for Carrying Out the Invention

[0013] Hereinafter, the present invention will be described in detail according to the mode for carrying out the present invention shown in the drawings.

[0014] In the first mode for carrying out the present invention shown in FIGS. 1 to 8, 1 is a floor joint device installed between one body 3 provided via a joint part 2 and the other body 4 having a floor surface formed at a position lower than the floor surface of this one body 3.

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

[0016] Here, the left - right direction is the left - right direction in FIG. 1 (plan view) (the longitudinal direction of the joint plate 8), the front - rear direction is the up - down direction in FIG. 1 (the direction perpendicular to the left - right direction, the width direction of the joint plate 8), and the up - down direction is the up - down direction in FIG. 2 (the thickness direction of the joint plate 8).

[0017] In addition, in the present invention, the body refers to a building such as a building, a road, a slab, an elevator shaft, etc. where a joint plate can be installed, and the entrance refers not only to an entrance provided with a door or a gate, but also includes a passage through which people, vehicles 21, etc. can pass.

[0018] As shown in FIGS. 1 and 2, the floor joint device 1 of this embodiment includes a first joint plate support portion 5 provided on one housing 3, a second joint plate support portion 6 provided on the other housing 4 so as to face the first joint plate support portion 5 through the joint portion 2, a joint plate 8 having one end supported by the first joint plate support portion 5 and attached in a locked state to a locking post 7 provided on the first joint plate support portion 5, and the other end supported by the second joint plate support portion 6, and a load receiving mechanism 9 that receives a lateral load (particularly, a load in the direction of the other housing applied to the joint plate 8) applied to the joint plate 8 when the vehicle 21 is passing.

[0019] A first joint plate support portion 5 is formed on one housing 3. In this embodiment, as shown in FIG. 3, the first joint plate support portion 5 is a recessed portion formed to extend in the front-rear direction on the floor surface on the joint portion 2 side of one housing 3. A locking post 7 that is inserted into a post case 10 provided on the joint plate 8 is provided on the first joint plate support portion 5.

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

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

[0022] [[ID=十六]]This second joint plate support portion 6 is formed to have a length that allows the joint plate 8 to slide in the lateral direction during an earthquake. In addition, a ramp surface 12 on which the joint plate 8 rides up is formed at the end of the second joint plate support portion 6 on the side opposite to the joint portion 2 when the joint portion 2 becomes narrower due to an earthquake.

[0023] In this embodiment, the ramping surface 12 is formed in this manner, but the ramping surface 12 may be omitted, and the second joint plate support portion 6 may be substantially flat with the floor surface of the other structural frame 4.

[0024] As shown in Figure 4, for example, the joint plate 8 consists of a metal joint plate body 13 that is roughly rectangular in plan view and formed in the shape of a shallow dish, 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 tiles or bricks attached to the upper 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 the load-receiving mechanism 9, which will be described later, is provided at the bottom of one end of the joint plate 8.

[0026] In normal operation, as shown in Figures 1 and 2, for example, one or more of these joint plates 8 are provided in the vertical direction (relative to Figure 1) of the joint section 2. One end of the joint plate 8 is supported in the installed state, and the other end is directly or indirectly supported (via a support plate, etc.) by the second joint plate support section 6.

[0027] In this embodiment, multiple joint plates 8 are supported, and adjacent joint plates 8 are arranged with virtually no gaps in the front-to-back direction. In this embodiment, there is a gap of about 2 mm between adjacent joint plates 8. However, "virtually no gaps" includes not only the state in which adjacent joint plates 8 are in contact, but also the case where there is a slight gap of a few millimeters between them.

[0028] By the way, in this embodiment, a shallow dish-shaped joint plate body 13 is used, with a filling member 14 filled inside the joint plate body 13 and a decorative plate 15 provided. However, a joint plate 8 using a solid plate-shaped joint plate body 13 may also be used, or a joint plate 8 without a decorative plate 15 or cover plate 17 may also be used.

[0029] Furthermore, although the drawing shows an example where 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 a decorative panel).

[0030] As shown in Figure 5, the load-bearing mechanism 9 is provided at the bottom of one end of the joint plate 8 and consists 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 structural members 3 and having an engaged portion 20 that is constantly engaged with the engaging portion 19 of the engaging member 18. The mechanism is designed so that the engaging portion 19 and the engaged portion 20 engage when the joint plate 8 is installed.

[0031] Here, "permanently engaged" includes not only the state in which the joint plate 8 is almost tightly engaged under normal circumstances, but also the case in which this engagement is momentarily released when the other end of the joint plate 8 rises, but then the engagement returns to the same state as under normal circumstances when the shaking caused by the earthquake stops.

[0032] The engaging portion 19 and the engaged portion 20 are designed to withstand the lateral load applied to the joint plate 8 when a vehicle passes over it, and to not obstruct the upward movement of the other end of the joint plate 8 when it rises upward during an earthquake.

[0033] The engaged portion 20 is preferably formed in a concave shape, while the engaging portion 19 corresponding to the engaged portion 20 is preferably formed in a convex shape. More preferably, as in this embodiment, the engaged portion 20 is formed in a substantially semicircular groove, and the engaging portion 19 is preferably formed in a substantially semicircular shape that engages with the engaged portion 20. In addition, the other side of the structure may have an arc shape or an inclined surface shape for the engaging portion 19 and the engaged portion 20.

[0034] The engaging member 18 is a member whose tip (lower end) has a substantially semicircular engaging portion 19. In this embodiment, a pair of these engaging members are provided on the bottom surface of one end of the joint plate 8 (joint plate body 13). The engaging member 18 may be integrally formed with the joint plate body 13, or it may be fixed by welding or the like. 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-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 structural members 3 by anchor bolts or the like so as to correspond to the engaged member 18, and a groove-shaped engaged portion 20 is formed on its upper surface.

[0036] Under normal conditions, the engaging portion 19 and the engaged portion 20 are engaged, and can withstand loads in the left-right direction (parallel to the longitudinal direction of the joint plate 8).

[0037] In addition, when a vehicle 21 or the like passes over it, as shown in Figure 6, the rotation of the tires generates a force that pushes the upper surface of the joint plate 8 toward the other side of the structure 4, resulting in 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 engaged portion 20 of the load receiving mechanism 9, thus preventing the load from being transmitted to the locking pile 7.

[0038] When the structural members 3 and 4 sway from side to side during an earthquake, causing the joint 2 to narrow, the joint plate 8 rides up onto the inclined surface 12 of the second joint plate support 6, as shown in Figure 7, absorbing the swaying caused by the earthquake. Even if the joint plate 8 rises up with a slight lateral displacement at this time, once the swaying caused by the earthquake stops, the engaging portion 19 and the engaged portion 20 act as guides to correct the lateral displacement of the joint plate 8, returning it to an engaged state and automatically returning it to its original position.

[0039] When the structural members 3 and 4 sway from side to side during an earthquake, causing the joint 2 to widen, the joint plate 8 slides from side to side on the second joint plate support 6, as shown in Figure 8, absorbing the shaking caused by the earthquake. [Industrial applicability]
