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, a floor joint device using a joint plate having a certain weight is widely known. Such a floor joint device includes, for example, "a joint plate support recess formed in a joint side floor body of one of the left and right buildings built via a joint portion so as to open to the joint portion, a joint plate slide movement support recess formed in a joint side floor body of the other building corresponding to the joint plate support recess so as to open to the joint portion, a joint plate attached so as to cover the joint plate slide movement support recess and the joint plate support recess, and a guide mechanism using an inclined surface for guiding the tip of the joint plate onto the floor surface of the other building when the joint portion formed at the tip of the joint plate and a portion on the side opposite to the joint portion of the joint plate slide movement support recess becomes narrow, a wedge-shaped or inverted L-shaped support piece fixed to the joint plate support recess and having an upper portion protruding in the direction opposite to the joint portion, and a support piece insertion recess into which the support piece formed at the rear end of the joint plate is inserted" (Patent Document 1).

[0003] However, in such a floor joint device, although the upper part of the joint plate is filled with a filling member in a shallow dish shape made of a metal material so that a vehicle or the like can pass through, and it is firmly formed, if a vehicle or the like passes through for a long time, the joint plate body gradually bends, and there is a risk that a gap will occur between the joint plates.

[0004] In addition, there is a risk that rainwater may enter between adjacent joint plates during rainy days or the like, and the rainwater may fall below the joint portion.

Summary of the Invention

Problems to be Solved by the Invention

[0006] In view of the above-mentioned conventional drawbacks, the present invention aims to provide a floor joint device that can prevent damage and deformation when heavy objects such as vehicles pass, prevent rainwater from falling below the joint part from between the joint plates, and absorb shaking movement caused by an earthquake.

[0007] The above and other objects and novel features of the present invention will become more fully apparent when the following description is read in conjunction with the accompanying drawings.

[0008] However, the drawings are for illustrative purposes only and do not limit the technical scope of the present invention.

Means for Solving the Problems

[0009] In order to achieve the above object, the floor joint device of the present invention according to claim 1 is a floor joint device that closes a joint part between one body and the other body, and includes a first joint plate support part provided on the one body, a second joint plate support part formed on the other body, a support joint plate and a supported joint plate that are attached in a state where one end side is supported by the first joint plate support part and the other end side is supported by the second joint plate support part, and a seal member provided between the support joint plate and the supported joint plate to prevent intrusion of rainwater. The support joint plate and the supported joint plate are Orthogonal to the longitudinal direction of the support target plate or the supported target plate alternately arranged in a direction, and one of the support joint plates includes a support joint plate main body and a support part formed in a notch shape on a side surface of the support joint plate main body in the Orthogonal to the longitudinal direction direction and having a substantially crank-shaped cross section in a sectional view. The other supported joint plate includes a supported joint plate main body and the Covered side surface of the support joint plate main bodyOrthogonal to the longitudinal direction It is formed in a notch shape on the side surface in the direction, and is composed of a supported portion having a substantially crank shape in a cross-sectional view that substantially abuts against the support portion.

[0010] The support portion of the floor joint device according to claim 2 is characterized in that an inclination is provided in the longitudinal direction of the support joint plate body.

[0011] The floor joint device according to claim 3 Support part is characterized in that a rainwater receiving portion capable of receiving rainwater is formed when rainwater intrudes.

[0012] The rainwater receiving portion of the floor joint device according to claim 4 is characterized in that it is formed in a groove shape extending in the longitudinal direction of the support joint plate body.

Effects of the Invention

[0013] As is clear from the above description, the following effects can be obtained in the present invention. (1) In the invention according to claim 1, the support joint plate and the supported joint plate are alternately arranged in the front-rear direction of the joint portion, and a supported portion having a substantially crank shape in a cross-sectional view that abuts against the support portion in a substantially surface-contact state is formed. Therefore, the joint plate is arranged in a state where the supported portion is supported by the support portion. Therefore, the plate thickness (height dimension) of the side portion of the joint plate becomes smaller than that of a normal joint plate, and the deflection of the support joint plate and the supported joint plate can be prevented when a heavy object such as a vehicle passes through because they support each other. (2) Further, since a supported portion having a substantially crank shape in a cross-sectional view that abuts against the support portion in a substantially surface-contact state is formed, even when the side portions of the support joint plate and the supported joint plate are slightly deflected, the support portion is located below between the support joint plate and the supported joint plate, and the opening of the joint portion can be prevented. (3) Since a seal member is provided between the support joint plate and the supported joint plate, it is possible to prevent rainwater from intruding between the joint plates and falling below the joint portion. (4) Since the support target plate is formed with a support portion, even when the gap between the support target plate and the supported target plate becomes large, the seal member can be supported by this support portion, and it is possible to prevent the seal member from falling downward. (4) Also in the invention according to claim 2, the same operational effects as those in the above (1) to (3) can be obtained. Further, since the support portion is inclined in the longitudinal direction of the support target plate, even if a small amount of rainwater intrudes from between the support target plate and the supported target plate or the like, the rainwater can be drained to the housing side due to this inclination. (5) Also in each of the inventions according to claim 3 and claim 4, the same operational effects as those in the above (1) to (4) can be obtained. Further, even if a small amount of rainwater intrudes, the rainwater receiving portion can receive the rainwater, and it is possible to prevent the rainwater from falling below the joint portion.

Embodiments for Carrying Out the Invention

[0015] Hereinafter, the present invention will be described in detail according to the embodiments for carrying out the present invention shown in the drawings.

[0016] In the first embodiment for carrying out the present invention shown in FIGS. 1 to 10, reference numeral 1 denotes a floor joint device installed between one housing 3 and the other housing 4 provided via a joint portion 2.

[0017] Note that the left-right direction is the left-right direction in FIG. 1 (plan view) (the longitudinal direction of the support joint plate 7), the front-rear direction is the up-down direction in FIG. 1 (the width direction of the support joint plate 7, the direction orthogonal to the longitudinal direction), and the up-down direction is the up-down direction in FIG. 2 (the thickness direction of the support joint plate 7).

[0018] In the present invention, the housing 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, etc. can pass.

[0019] As shown in FIGS. 1 to 3, the floor joint device 1 of the present embodiment includes a first joint plate support portion 5 provided on one housing 3, a second joint plate support portion 6 formed on the other housing 4, a support joint plate 7 and a supported joint plate 8 which are attached with one end portion side supported by the first joint plate support portion 5, the other end portion side supported by the second joint plate support portion 6, and closing the joint portion 2, and a seal member 20 provided between the support joint plate 7 and the supported joint plate 8 to prevent intrusion of rainwater.

[0020] A first joint plate support portion 5 is formed on one housing 3. In this embodiment, as shown in FIG. 2 for example, 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, and locking piles 10 to be inserted into pile cases 9 provided at both front and rear ends of one end portion of the support joint plate 7 and the supported joint plate 8 described later are provided. Note that a metal member such as a substantially angled or substantially crank-shaped member may be fixed to the wall surface on the joint portion 2 side of one housing 3 to serve as the first joint plate support portion 5.

[0021] A second joint plate support portion 6 is formed on the other housing 4. The second joint plate support portion 6 is formed to have a length that allows the support joint plate 7 and the supported joint plate 8 to slide in the left-right direction during an earthquake. Further, a rising inclined surface 11 on which the support joint plate 7 and the supported joint plate 8 ride up is formed at the end portion 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.

[0022] Now, a plurality of support target plates 7 and supported target plates 8 are provided respectively. In normal times, as shown in FIG. 1 etc., a locking pile 10 provided on the first target plate support portion 5 is inserted into a pile case 9 formed at one end, and one end is supported in the attached state, and the other end is directly or indirectly (via a support plate etc.) supported by the second target plate support portion 6, and a plurality of them are provided alternately in the front - rear direction of the joint portion 2 without gaps. In FIG. 1, a total of 4 support target plates 7 and supported target plates 8 are arranged, but the number is not limited.

[0023] By the way, the support target plate 7 and the supported target plate 8 are arranged alternately in the front - rear direction. By arranging them in this way, the support portion 12 and the supported portion 13 described later can be made to be in a substantially surface - contact state and substantially abutted against each other, and the supported portion 13 can be supported efficiently. Note that "substantially abutted" includes not only the state where the entire support portion 12 and the supported portion 13 are in perfect contact, but also the case where there are some non - contact parts.

[0024] Between this support target plate 7 and the supported target plate 8, a seal member 20 for preventing the intrusion of rainwater is provided respectively. This seal member 20 is a substantially square - plate - shaped resin sheet etc., and is provided so as to be in close contact with the side surfaces of the support target plate 7 and the supported target plate 8. Since the support target plate 7 has a substantially crank - shaped part (the part where the support portion 12 is formed) whose upper surface is substantially horizontal, when the seal member 20 is provided, this seal member 20 can be easily installed without falling downward.

[0025] The seal member 20 may be provided in an adhesive state on the side surface of the support joint plate 7 or the supported joint plate 8. However, in this embodiment, after arranging the support joint plate 7 and the supported joint plate 8, a seal member 20 having a cross-sectional shape slightly rusty-shaped without performing adhesion or the like is inserted into the gap between these joint plates 7 and 8 and fixed. Specifically, these support joint plates 7 and supported joint plates 8 have a gap of about several millimeters in the front-rear direction in the use state, and in this embodiment, they are alternately installed with a gap of about 2 mm in the front-rear direction and substantially without a gap. The seal member 20 is arranged in a state of being inserted into this gap of about 2 mm.

[0026] It is preferable to provide the upper surface of the seal member 20, the upper surface of the support joint plate 7, and the upper surface of the supported joint plate 8 to be flat.

[0027] On the other hand, as shown in FIGS. 4 to 6, for example, one support joint plate 7 has a pair of notch-shaped support portions 12 on the upper side corresponding to approximately half of the side surface 14a in the front-rear direction (width direction), and a support joint plate main body 14 made of a metal material having a rectangular upper surface. The pile case 9 provided on both sides in the front-rear direction at one end in the left-right direction of the support joint plate main body 14, and support portions 12 formed longitudinally on the side surface 14a in the front-rear direction (width direction) of the above-described support joint plate main body 14, and having a substantially horizontal upper surface as shown in FIG. 5 in a cross-sectional view. A filling member 15 such as mortar or concrete filled inside the support joint plate main body 14, a decorative plate 16 such as a marble tile or a brick attached to the upper surface of the filling member 15, and a cover plate 18 attached to the other end side of the support joint plate main body 14 via a hinge member 17.

[0028] The support portion 12 is formed in a substantially crank-shaped cross-sectional view in which the lower side of the support target plate body 14 has a large dimension (the dimension of the bottom surface of the support target plate body 14 is larger than the dimension of the upper surface), and is formed on the entire surface so as to extend in the left-right direction on the side surface 14a in the width direction of the support target plate body 14. The cross-sectional shape of the upper surface 12a (the surface that supports the supported portion 13) of the support portion 12 is formed to be substantially horizontal. In the present embodiment, it is inclined at an angle of several degrees to about 10 degrees in the longitudinal direction of the support target plate body 14. Due to this inclination, the rainwater flowing into the support portion 12 flows to either the left or right housing 3, 4, and it is possible to prevent the rainwater from falling below the joint portion 2 by drainage means (not shown) provided in the housings 3, 4.

[0029] As the height of the upper surface 12a of the support portion 12, in the present embodiment, when the height of the support target plate body 14 is 100 mm, it is formed to be 40 mm (about 2 / 5 of the height of the joint plate), but this height can be appropriately changed. The dimension protruding in the front-rear direction is about 25 mm, but this length can also be appropriately changed.

[0030] Note that the support portion 12 may be formed on both side surfaces, or in the case of the support target plate 7 located at the end of the joint portion, the support portion 12 may be formed only on the side surface adjacent to the supported target plate 8.

[0031] The other supported target plate 8 with respect to the one support target plate 7 has, for example, as shown in FIGS. 7 and 8, a pair of supported portions 13 on the lower side corresponding to approximately half of the side surface 19a in the front-rear direction (width direction), and a supported target plate body 19 made of a metal material with a rectangular-shaped lower surface. The pile case 9 is provided on both sides in the front-rear direction at one end in the left-right direction of the supported target plate body 19. The supported portions 13 are formed longitudinally on the side surfaces 19a in the front-rear direction (width direction) of the supported target plate body 19, and are in a substantially surface-contact state with the support portions 12 as shown in FIG. 7, for example, and are formed in a substantially crank shape in cross-section. A filling member 15 such as mortar or concrete filled inside the supported target plate body 19, a decorative plate 16 such as a marble tile or a brick pasted on the upper surface of the filling member 15, and a cover plate 18 attached to the other end side of the supported target plate body 19 via a hinge member 17.

[0032] The supported portion 13 is formed in a substantially crank shape in cross-section such that the lower side of the supported target plate body 19 has a smaller dimension (the dimension of the bottom surface of the supported target plate body 19 is smaller than the dimension of the upper surface), and is formed on the entire surface so as to extend in the left-right direction on the side surface 19a in the width direction of the supported target plate body 19. This supported portion 13 is substantially in surface contact with the support portion 12 as a whole, and is formed such that the upper surfaces of the support target plate 7 and the supported target plate 8 are substantially flat. That is, in the present embodiment, the height of the supported surface 13a (the surface that contacts the support surface 12a) of the supported portion 13 is formed to be about 2 / 5 of the height of the supported target plate body 19, and the dimension in the front-rear direction of the portion recessed in the front-rear direction is formed to be about 25 mm.

[0033] Regarding this supported portion 13, it may also be formed on both side surfaces in the width direction of the supported target plate body 19, or in the case of the supported target plate 8 located at the end of the joint portion, the supported portion 13 may be formed only on the side surface adjacent to the support target plate 7.

[0034] Incidentally, when an inclination for draining rainwater is formed in the support portion 12, the supported portion 13 may also be formed with an inclination that substantially contacts the support portion 12 in a surface-contact manner.

[0035] By providing the support portion 12 and the supported portion 13, even when a large load is applied to the edge of the supported target plate 8 or the like, the support portion 12 can support the load, and the bending stress or the like applied to the supported target plate 8 can be reduced. Also, regarding the support target plate 7, when a large load is applied to its edge, by forming the support portion 12 and forming the side surface in the width direction in a substantially crank shape, the bending stress applied to the edge or the like can be reduced. Therefore, even when a large load is applied, the deflection of the support target plate 7 and the supported target plate 8 can be prevented. In the present embodiment, the support target plate 7 and the supported target plate 8 are formed such that substantially the entire surfaces of the support surface 12a and the supported surface 13a are in surface contact. However, the support target plate 7 and the supported target plate 8 may be formed such that the support surface 12a and the supported surface 13a are in surface contact to an extent that the load can be supported and mutual deflection can be prevented.

[0036] Incidentally, in the present embodiment, the support target plate 7 and the supported target plate 8 having a flat upper surface are used. However, a support target plate 7 or a supported target plate 8 having an inclination in the left-right direction (longitudinal direction), or a support target plate 7 or a supported target plate 8 having an inclination in the front-rear direction (a direction orthogonal to the longitudinal direction) may also be used. Further, reinforcing members (not shown) such as a plurality of ribs extending in the longitudinal direction of the support target plate body 14 and the supported target plate body 19 or lattice-shaped ribs may be fixedly provided inside the shallow-dish-shaped support target plate body 14 and the supported target plate body 19. When such a reinforcing member is provided, the lower end portion of the reinforcing member is fixed to the bottom inside the support target plate body 14 and the supported target plate body 19 by welding or the like, and then the filling member 15 is filled.

[0037] In addition, in the present embodiment, a shallow dish-shaped support joint plate body 14 and a supported joint plate body 19 are used, and a filling member 15 is filled inside the support joint plate body 14 and the supported joint plate body 19, and a decorative plate 16 is provided. However, for example, a support joint plate 7 and a supported joint plate 8 using plate-shaped (solid) support joint plate bodies 14 and supported joint plate bodies 19 may be used, or support joint plates 7 and supported joint plates 8 not provided with a decorative plate 16, a cover plate 18, etc. may be used.

[0038] When the building frames 3 and 4 swing in the left-right direction due to an earthquake and the joint part 2 becomes narrower, as shown in FIG. 9, the support joint plate 7 and the supported joint plate 8 ride up on the upward-sloping surface 11 of the second joint plate support part 6 to absorb the swinging motion due to the earthquake.

[0039] When the building frames 3 and 4 swing in the left-right direction due to an earthquake and the joint part 2 becomes wider, as shown in FIG. 10, the support joint plate 7 and the supported joint plate 8 slide in the left-right direction on the second joint plate support part 6 to absorb the swinging motion due to the earthquake.

[0040] [Different forms for implementing the invention] Next, different forms for implementing the present invention shown in FIGS. 11 and 15 will be described. In the description of these different forms for implementing the present invention, the same reference numerals are given to the same components as those in the first form for implementing the present invention, and redundant descriptions are omitted.

[0041] In the second form for implementing the present invention shown in FIGS. 11 and 15, the main difference from the first form for implementing the present invention is that a support joint plate 7A having a rainwater receiving part 21 formed partially is used. Even with a floor joint device 1A using such a support joint plate 7A, the same operational effects as those in the first form for implementing the present invention can be obtained.

[0042] In this embodiment, a rainwater receiving portion 21 is formed in a part of the support portion 12A. Specifically, the support portion 12A is formed in a crank shape that is close to a substantially horizontal Z shape. The lower bent portion of this substantially horizontal Z shape serves as the rainwater receiving portion 21, and the upper bent portion serves as the portion (support surface 12a) that supports the supported target plate 8. In this embodiment, since such a support portion 12A is used, the support portion 12A and the supported portion 13 are substantially in contact with each other in a narrow surface contact state or a line contact state.

[0043] In this embodiment, the rainwater receiving portion 21 is formed in a groove shape with an arc-shaped cross section, and is formed so as to be able to receive rainwater that has fallen from the side surface of the supported target plate body 19 of the supported target plate 8. Note that the cross-sectional shape of the rainwater receiving portion 21 may be a groove shape such as an upwardly substantially U shape.

[0044] Further, in this embodiment, the support portion 12A and the rainwater receiving portion 21 are inclined at an angle of several degrees to about 10 degrees in the longitudinal direction of the support target plate body 14. Due to this inclination, the rainwater that has flowed into the support portion 12 or the rainwater receiving portion 21 flows to either the left or right housing 3, 4, and it is possible to prevent the rainwater from falling below the joint portion 2 by drainage means (not shown) provided in the housings 3, 4.

[0045] Note that, in the embodiment of the present invention, a support target plate having a groove-shaped rainwater receiving portion has been described, but for example, one having a rainwater receiving portion in the shape of a drain port may also be used.

[0046] Further, it is not necessary to provide an inclination on the upper surface of the support portion or the joint plate.
