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 that closes a joint between floor surfaces and does not allow rainwater to fall into the joint has been described as "a floor joint device that closes a joint between one and the other of two frames, comprising: a first joint plate support portion provided on the one frame; a second joint plate support portion provided on the other frame; a rainwater drain joint plate that is supported at one end by the first joint plate support portion and at the other end by the second joint plate support portion, and that has a rainwater drain portion on at least one side in the front-to-rear direction; A floor joint device is known which is composed of a rainwater receiving joint plate, one end of which is supported by the first joint plate support portion and the other end of which is supported by the second joint plate support portion, and a rail-shaped rainwater receiving member which is installed opposite the rainwater discharge portion, and the rainwater discharge portion is composed of a recess formed so that the rail-shaped rainwater receiving member can fit in, and a rainwater drip portion formed above the recess and protruding downward so that rainwater can fall onto the rainwater receiving member (Patent Document 1).

[0003] However, although such floor joint devices can catch rainwater, they require the production of multiple types of joint plates, which makes manufacturing difficult and increases costs. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Publication No. 2019-7317 Summary of the Invention [Problem to be solved by the invention]

[0005] In view of the above-mentioned conventional drawbacks, the present invention aims to provide a floor joint device that primarily aims to rationalize the manufacturing equipment for joint plates and that can prevent rainwater from falling below the joints between the structural members by catching rainwater that falls between the joint plates after installation.

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

[0007] In order to achieve the above-mentioned object, the floor joint device of the present invention described in claim 1 is a floor joint device that seals a joint between one body and another body, and is composed of a first joint plate support portion provided on the one body, a second joint plate support portion provided on the other body, a plurality of joint plates that are attached with one end supported by the first joint plate support portion and the other end supported by the second joint plate support portion and that seal the joint portion, and gutter members that are provided respectively between the plurality of joint plates and that are attached with one end by a hinge to the first joint plate support portion and the other end supported by the second joint plate support portion and that can receive rainwater, and the joint plates have a roughly crank-shaped recess formed on the widthwise side facing the adjacent joint plates, and the gutter members are arranged to be positioned in the recess, and are a floor joint device that can receive water that falls from the widthwise end of the joint plates.

[0008] The recess of the floor joint device according to claim 2 is formed in a crank shape that is roughly N-shaped or roughly inverted N-shaped in cross section so that rainwater falls reliably into the gutter member.

[0009] The gutter member of the floor joint device described in claim 3 has one end attached to the one of the main bodies via a gutter member attachment device, and the gutter member attachment device is characterized by being composed of a cylindrical guide member fixed to the one of the main bodies, a attachment body that is inserted into the guide member so as to be able to move in the vertical direction and whose upper end is attached to the gutter member via a hinge, and a biasing device that biases the gutter member toward the one of the main bodies. [Effects of the Invention]

[0010] As is clear from the above description, the present invention provides the following effects. (1) In the invention described in claim 1, for example, referring to Figure 5, a recess is formed on the side of the joint plate, and a gutter member with an open upper end is provided so as to be positioned in the recess, so there is no need to manufacture multiple types of joint plates. In addition, since joint plates can be made to a single specification, it is possible to rationalize manufacturing equipment and reduce manufacturing costs. (2) The invention described in claim 2 also provides the same effect as (1) above, and since the recess is formed in a crank shape that is approximately N-shaped or approximately inverted N-shaped in cross section, rainwater can be reliably received by the gutter member. (3) In the invention described in claim 3, the same effects as those in (1) and (2) above can be obtained, and rainwater can be guided to the second joint plate support portion side, allowing for efficient drainage.

DETAILED DESCRIPTION OF THE INVENTION

[0012] 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.

[0013] In the first embodiment of the present invention shown in Figures 1 to 8, 1 is a floor joint device installed between one body 3 and the other body 4 provided with a joint portion 2 therebetween.

[0014] The left-right direction refers to the left-right direction in Figure 1 (plan view) (the longitudinal direction of the joint plate 7), the front-to-back direction refers to the up-and-down direction in Figure 1 (the width direction of the joint plate 7, 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 joint plate 7).

[0015] 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.

[0016] As shown in Figures 1 to 3, 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 formed on the other frame 4, a plurality of joint plates 7 attached with one end supported by the first joint plate support portion 5 and the other end supported by the second joint plate support portion 6, and covering the joint portion 2, and gutter members 9 provided respectively between the plurality of joint plates 7, attached to one of the frames 3 while being supported by the first joint plate support portion 5 or the first joint plate support portion, and the other end supported by the second joint plate support portion 6.

[0017] A first joint plate support portion 5 is formed on one of the skeletons 3, and in this embodiment, as shown in Figure 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 locking piles 11 that are inserted into pile cases 10 provided on both front and rear ends of one end of a joint plate 7 (described later). Note that the first joint plate support portion 5 may also be formed by fixing a metal member that is approximately angle-shaped or approximately crank-shaped to the wall surface on the joint portion 2 side of one of the skeletons 3.

[0018] A second joint plate support part 6 is formed on the other body 4, and this second joint plate support part 6 is formed to a length that allows the 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 12 is formed that the joint plate 7 can climb up on if the joint part 2 narrows due to an earthquake.

[0019] 1 and 2, for example, a plurality of joint plates 7 are normally arranged vertically (with reference to FIG. 1) in the joint section 2, preferably with almost no gaps, with one end supported by a locking pile 11 attached to the first joint plate support section 5 inserted into a pile case (e.g., rectangular in plan view) 10 formed at one end, and the other end supported directly or indirectly (via a support plate, etc.) by the second joint plate support section 6, as shown in FIG. 1 and 2 for example. In this embodiment, the joint plates 7 are arranged with a gap of about 2 mm between them, and "almost no gap" includes not only a state in which adjacent joint plates 7 are arranged in abutting contact with each other, but also a state in which they are arranged with a slight gap of a few millimeters between them.

[0020] As shown in Figures 4 and 5, this joint plate 7 is composed of a metal joint plate main body 13 that is approximately rectangular in plan view, the pile case 10 provided on both sides of one longitudinal end of the joint plate main body 13, a recess 14 that is approximately crank-shaped in cross section formed on at least one of the widthwise side surfaces 13a of the joint plate main body 13, a filling member 15 such as mortar or concrete filled inside the joint plate main body 13, a decorative panel 16 such as marble tile or brick attached to the top surface of the filling member 15, and a cover plate 18 attached to the other end side of the joint plate main body 13 via a hinge member 17.

[0021] In this embodiment, the joint plate body 13 has a flat upper surface, but it is also possible to use a joint plate body 13 that is inclined in the left-right direction (longitudinal direction) or a joint plate body 13 that is inclined in the front-to-back direction (direction perpendicular to the longitudinal direction). Furthermore, reinforcing materials (not shown), such as multiple ribs or lattice-shaped ribs, extending in the longitudinal direction of the joint plate body 13 may be fixedly provided inside the shallow dish-shaped joint plate body 13. When such reinforcing materials are provided, the lower end of the reinforcing material is fixed to the bottom of the interior of the joint plate body 13 by welding or the like, and then the filler 15 is filled in.

[0022] In this embodiment, a shallow dish-shaped joint plate body 13 is used, and a filling material 15 is filled inside this joint plate body 13 and a decorative panel 16 is provided, but for example, a joint plate 7 using a plate-shaped (solid) joint plate body 13 may also be used, or a joint plate 7 without a decorative panel 16 or cover plate 18, etc. may also be used.

[0023] The recess 14 is formed in a roughly crank-shaped cross section with a smaller dimension on the lower side of the joint plate main body 13 (the dimensions of the bottom surface of the joint plate main body 13 are smaller than the dimensions of the top surface), and is formed on the side that faces (roughly abuts) the adjacent joint plate 7.

[0024] Therefore, it is sufficient to form a recess 14 on only one side of the joint plate 7 provided at the end, and it is not necessary to form a recess on the side that does not face (does not substantially abut) another joint plate 7.

[0025] The recess 14 is formed on the entire widthwise side surface 13a of the joint plate body 13 so as to extend in the left-right direction, and in this embodiment, the shape of the recess 14 is formed in a crank shape that is roughly N-shaped or roughly inverted N-shaped in cross section so that rainwater can reliably fall into the gutter member. By making the recess 14 shaped in this way, rainwater collects in the convex portion on the downward side, ensuring that the rainwater can fall downward from that position. This convex portion is located on a roughly vertical line with the front-to-rear side surface of the joint plate 7, ensuring that rainwater can fall reliably into the gutter member 9 provided in the recess 14.

[0026] A gutter member 9 having a generally upward U-shape in cross section is provided in this recess 14, and the generally middle portion of this gutter member 9 in the width direction is located below the end portion of the joint plate body 13 in the width direction, and is preferably formed in a shape that generally abuts against the lower side surface 14a of the recess 14. Note that "generally abutting" does not only mean a state of contact, but also a state of being close with a small gap. Note that in this embodiment, providing the gutter member 9 in the recess 14 specifically means placing the gutter member 9 in the gap portion formed by the recesses 14 of adjacent joint plates 7.

[0027] One end of this gutter member 9 is attached to the one of the frames via a gutter member attachment 8, and this gutter member attachment 8 is composed of a cylindrical guide member 21 fixed to the joint side wall surface of the one of the frames 3, a bar-shaped attachment main body 23 that is inserted into the guide member 21 so as to be able to move up and down and whose upper end is attached to the bottom of the gutter member 9 via a hinge 22, and a coil spring-like biasing device 24 that constantly biases the gutter member 9 toward the one of the frames 3. By attaching the one end side in this way, the attachment main body 23 can move up and down and the other end side can rotate up and down around the hinge 22, and can climb up the climbing slope 12 in the same way as the joint plate 7 during an earthquake.

[0028] Furthermore, this gutter member 9 is formed to a length that can cover at least the portion located above the joint portion 2 when the joint plate 7 is installed in the joint portion 2. In this embodiment, it is provided from one end side to the entire other end side of the joint plate body 13, and is provided at a downward slope so that rainwater dripping between the joint plates 7 flows into the second joint plate support portion 6. In addition, when the second joint plate support portion 6 is arranged so as to have a downward slope so that rainwater flows into it, as in this embodiment, or when the gutter member 9 is arranged so as to be approximately horizontal, it is desirable to provide a cover member 19 to cover the end portion on one end side.

[0029] In this embodiment, rainwater received by the gutter member 9 flows down the gutter member 9 to the second joint plate support portion 6 of the other frame 4, and then flows from the second joint plate support portion 6 down to a drainage gutter 20 provided on the wall surface of the other frame 4 for drainage. Therefore, the second joint plate support portion 6 may be provided with a groove-like slope to allow rainwater to flow into the drainage gutter 20, or the second joint plate support portion 6 itself may be slightly sloped (not shown). Alternatively, drainage means for discharging rainwater from the second joint plate support portion 6 to the outside may be provided instead of providing the drainage gutter 21. Alternatively, the gutter member 9 may be sloped to allow rainwater to flow to the first joint plate support portion 5, and the drainage gutter 20 may be provided on the wall surface of one frame 3. The drainage gutter 20 may be of any shape, size, or material as long as it is capable of draining rainwater and the like.

[0030] However, this recess 14 does not appear on the upper surface of the joint plate 7, and when in use, the recess 14 is not visible, so patterns that appear on the upper surface of the joint plate, such as the decorative panel 16, are not damaged, and the beauty of the appearance can be maintained.

[0031] 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 7, the joint plate 7 and gutter member 9 climb up the sloped climbing surface 12 of the second joint plate support section 6 and absorb the shaking caused by the earthquake.

[0032] When the bodies 3 and 4 shake left and right during an earthquake, widening the joint 2, the joint plate 7 and gutter member 9 slide left and right as shown in FIG. 8, absorbing the shaking caused by the earthquake.

[0033] In the embodiment of the present invention, the gutter member is attached to one of the main bodies using a gutter member attachment device, but the gutter member may also be attached to the first joint plate support portion via a hinge or the like, or a pile case may be formed on the tub member and attached using a locking pile or the like.
