Description

[Technical field]

[0001] The present invention relates to a floor joint device that closes a joint between frames provided with a joint therebetween. [Background technology]

[0002] 2. Description of the Related Art Conventionally, as a floor joint device for sealing a joint portion between floor surfaces, a floor joint device using a joint plate having a certain degree of weight has been widely known. Such a floor joint device is known, for example, as comprising "a joint plate support recess formed in the floor structure on the joint side of one of the buildings erected on the left and right sides via the joint portion so as to open to the joint portion, a joint plate slide movement support recess formed in the floor structure on the joint side of the other building corresponding to the joint plate support recess so as to open to the joint portion, a joint plate attached to cover the joint plate slide movement support recess and the joint plate support recess, a guide mechanism using an inclined surface that guides the tip of the joint plate onto the floor surface of the other building when the joint formed between the tip of the joint plate and the part on the opposite joint side of the joint plate slide movement support recess becomes narrow, a wedge-shaped or inverted L-shaped support piece whose upper part is fixed to the joint plate support recess and protrudes toward the opposite joint portion, and a support piece insertion recess formed at the rear end of the joint plate into which the support piece is inserted" (Patent Document 1).

[0003] However, in this type of floor joint device, the joint plate body is formed into a shallow dish shape from metal material and filled with a filling material to allow vehicles and the like to pass over the top of the joint plate, making it sturdy; however, if vehicles and the like pass over it for a long period of time, the joint plate body will gradually sag, and there is a risk of gaps appearing between the joint plates.

[0004] [Patent Document 1] JP 2001-329625 A 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 will not be damaged or deformed when heavy objects such as vehicles pass over it, and that can 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 taken in conjunction with the accompanying drawings.

[0007] However, the drawings are for illustrative purposes only and are not intended to 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 one frame and another frame, and is composed of a first joint plate support part provided on the one frame, a second joint plate support part formed on the other frame, and a supporting joint plate and a supported joint plate attached with one end side supported by the first joint plate support part and the other end side supported by the second joint plate support part, the supporting joint plate and the supported joint plate being alternately arranged in a direction perpendicular to the longitudinal direction of the supporting joint plate or the supported joint plate, and one of the support joint plates is arranged between a supporting joint plate main body and a supporting joint plate main body perpendicular to the longitudinal direction of the supporting joint plate main body. direction The other supported joint plate is composed of a supported joint plate main body and a supported portion which is formed in a notch shape on the side of the supported joint plate main body in a direction perpendicular to the longitudinal direction of the supported joint plate main body and which abuts the support portion in a substantially surface-to-surface contact state. The floor joint device according to claim 2 is characterized in that the insides of the supporting joint plate body and the supported joint plate body are filled with a filling material. Effect of the Invention

[0009] As is clear from the above description, the present invention provides the following advantages. (1) In each of the inventions described in claims 1 and 2, the supporting joint plates and the supported joint plates are arranged alternately in the front-to-rear direction of the joint portion to form a supported portion that is approximately crank-shaped in cross section and abuts the supporting portion in an approximately surface-contact state, so that the joint plate is arranged with the supported portion supported by the supporting portion. Therefore, the plate thickness (height dimension) of the side of the joint plate is smaller than that of a normal joint plate, and because they support each other, deflection of the supporting joint plate and the supported joint plate can be prevented when a heavy object such as a vehicle passes through. (2) Furthermore, the supported part is formed to have a generally crank-shaped cross section which abuts against the supporting part in a roughly surface-to-surface contact state. Therefore, even if the side of the supporting joint plate or the supported joint plate is slightly deflected, the supporting part is located below and between the supporting joint plate and the supported joint plate, so that the joint part can be prevented from opening.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0011] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to the embodiments shown in the drawings.

[0012] In the first embodiment for carrying out the present invention shown in Figures 1 to 9, reference numeral 1 denotes a floor joint device installed between one body 3 and another body 4 provided with a joint portion 2 interposed therebetween.

[0013] Note that the left-right direction refers to the left-right direction in Figure 1 (plan view) (the longitudinal direction of the support joint plate 7), the front-to-back direction refers to the up-down direction in Figure 1 (the width direction of the support joint plate 7, a direction perpendicular to the longitudinal direction), and the up-down direction refers to the up-down direction in Figure 2 (the thickness direction of the support joint plate 7).

[0014] In addition, in the present invention, the term "structure" refers to a structure such as a building, road, slab, elevator shaft, etc. in which a joint plate can be installed, and the term "entrance / exit" refers not only to an entrance / exit with a door or gate, but also to a passageway through which people, vehicles, etc. can pass.

[0015] As shown in Figures 1 to 3, the floor joint device 1 of this embodiment is composed of a first joint plate support part 5 provided on one of the structures 3, a second joint plate support part 6 formed on the other structure 4, and a supporting joint plate 7 and a supported joint plate 8 that are attached with one end side supported by the first joint plate support part 5 and the other end side supported by the second joint plate support part 6, and that seal the joint part 2.

[0016] A first joint plate support portion 5 is formed on one of the skeletons 3, and in this embodiment, as shown in Fig. 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 a locking pile 10 to be inserted into a pile case 9 provided on both front and rear ends of one end of a supporting joint plate 7 and a supported joint plate 8, which will be described later. Note that the first joint plate support portion 5 may be formed by fixing a metal member having a substantially angle or crank shape to the wall surface on the joint portion 2 side of one of the skeletons 3.

[0017] 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 supporting joint plate 7 and the supported 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 11 is formed on which the supporting joint plate 7 and the supported joint plate 8 climb up when the joint part 2 narrows due to an earthquake.

[0018] There are a plurality of supporting joint plates 7 and a plurality of supported joint plates 8, and normally, as shown in Fig. 1 etc., a locking pile 10 provided on the first joint plate support part 5 is inserted into a pile case 9 formed at one end, one end is supported in the installed state, and the other end is supported directly or indirectly (through a support plate etc.) by the second joint plate support part 6, and a plurality of them are provided alternately with no gaps in the front-to-rear direction of the joint part 2. In Fig. 1, a total of four supporting joint plates 7 and supported joint plates 8 are arranged, but this number is not limited to four.

[0019] The support joint plates 7 and the supported joint plates 8 are arranged alternately in the front-to-rear direction. By arranging them in this manner, the supporting portion 12 and the supported portion 13 described below can be engaged with each other in a state of approximate surface contact, thereby efficiently supporting the supported portion 13.

[0020] One of the support joint plates 7 is composed of a support joint plate main body 14 made of metal having a pair of notched support portions 12 on the upper side corresponding to approximately half of the side surface 14a in the front-to-rear (width direction) and having a rectangular upper surface, as shown in Figure 4, the pile case 9 provided on both front-to-rear sides of one left-to-right end of the support joint plate main body 14, support portions 12 formed in the longitudinal direction on each of the front-to-rear (width direction) side surfaces 14a of the support joint plate main body 14 described above, which are approximately crank-shaped in cross section and have an approximately horizontal upper surface, as shown in Figure 5, a filling member 15 such as mortar or concrete filled inside the support joint plate main body 14, a decorative panel 16 such as a tile or brick made of marble or the like 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.

[0021] In addition, this support portion 12 may be formed on both side surfaces, or in the case of a supporting joint 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 joint plate 8.

[0022] The other supported joint plate 8 for the one support joint plate 7 is composed of a supported joint plate main body 19 made of metal material having a pair of supported parts 13 on the lower side corresponding to approximately half of the side surface 19a in the front-to-rear (width direction) and with a rectangular underside, as shown in Figure 6, the pile case 9 provided on both front-to-rear sides of one left-to-right end of the supported joint plate main body 19, the supported parts 13 which are formed in the longitudinal direction on each of the front-to-rear (width direction) side surfaces 19a of the supported joint plate main body 19 and which are approximately crank-shaped in cross section and can abut in a state of approximately surface contact with the support parts 12, as shown in Figure 7, a filling member 15 such as mortar or concrete filled inside the supported joint plate main body 19, a decorative panel 16 such as a tile or brick made of marble or the like attached to the upper surface of the filling member 15, and a cover plate 18 attached to the other end side of the supported joint plate main body 19 via a hinge member 17.

[0023] Therefore, the external shape, size and thickness of the other supported joint plate 8 are, so to speak, the upside down appearance of one support joint plate 7. The supported portion 13 may also be formed on both widthwise sides of the supported joint plate body 19, or, in the case of the supported joint plate 8 located at the end of the joint portion, the supported portion 13 may be formed only on the side adjacent to the support joint plate 7.

[0024] In this embodiment, the support joint plate 7 and the supported joint plate 8 have a flat upper surface, but the support joint plate 7 and the supported joint plate 8 may have a slope in the left-right direction (longitudinal direction) or a slope in the front-back direction (direction perpendicular to the longitudinal direction). In addition, reinforcing materials (not shown) such as multiple ribs or lattice-shaped ribs extending in the longitudinal direction of the support joint plate body 14 and the supported joint plate body 19 may be fixedly provided inside the shallow dish-shaped support joint plate body 14 and the supported joint plate body 19. When providing such reinforcing materials, the lower end of the reinforcing materials is fixed to the bottom of the inside of the support joint plate body 14 and the supported joint plate body 19 by welding or the like, and then the filling material 15 is filled.

[0025] In addition, in this embodiment, a shallow dish-shaped support joint plate body 14 and supported joint plate body 19 are used, and the inside of these support joint plate body 14 and supported joint plate body 19 are filled with filling material 15 and provided with a decorative plate 16. However, for example, the support joint plate 7 and supported joint plate 8 may use a plate-shaped (solid) support joint plate body 14 and supported joint plate body 19, or the support joint plate 7 and supported joint plate 8 may not have a decorative plate 16 or cover plate 18, etc.

[0026] The support portion 12 is formed in a generally crank-like cross section with the lower side of the support joint plate body 14 being larger (the bottom surface of the support joint plate body 14 is larger than the top surface), and is formed on the entire surface of the side surface 14a in the width direction of the support joint plate body 14 so as to extend in the left-right direction. The upper surface 12a of the support portion 12 (the surface supporting the supported portion 13) is formed to be generally horizontal. In this embodiment, the height of the upper surface 12a of the support portion 12 is formed to be 40 mm (about 2 / 5 of the height of the joint plate) when the height of the support joint plate body 14 is 100 mm, but this height can be changed as appropriate. The dimension protruding in the front-rear direction is about 25 mm, but this length can also be changed as appropriate.

[0027] The supported portion 13 is formed in a generally crank-like cross section with a smaller dimension on the lower side of the supported joint plate body 19 (the dimension of the bottom surface of the supported joint plate body 19 is smaller than the dimension of the top surface), and is formed over the entire surface so as to extend in the left-right direction on the widthwise side surface 19a of the supported joint plate body 19. The supported portion 13 is in surface contact with the supporting portion 12 over the substantially entire surface, and is formed so that the upper surface of the support joint plate 7 and the upper surface of the supported joint plate 8 are substantially flat. That is, in this embodiment, the height of the supported surface 13a (the surface that abuts against the supporting surface 12a) of the supported portion 13 is formed to be about 2 / 5 of the height of the supported joint plate body 19, and the dimension of the portion recessed in the front-rear direction is formed to be about 25 mm in the front-rear direction.

[0028] Due to such a shape, even when a large load is applied to the edge of the supported joint plate 8, the support portion 12 can support the load and the bending stress applied to the supported joint plate 8 can be reduced. In addition, when a large load is applied to the edge of the support joint plate 7, the support portion 12 is formed and the side surface in the width direction is formed into a substantially crank shape, so that the bending stress applied to the edge can be reduced. Therefore, even when a large load is applied, the deflection of the support joint plate 7 and the supported joint plate 8 can be prevented. In this embodiment, the support joint plate 7 and the supported joint plate 8 are formed so that the support surface 12a and the supported surface 13a are substantially entirely in surface contact, but the support joint plate 7 and the supported joint plate 8 may be formed so that the support surface 12a and the supported surface 13a are in surface contact to the extent that the load can be supported and deflection can be prevented.

[0029] These supporting joint plates 7 and supported joint plates 8 are installed alternately with almost no gaps at intervals of about several millimeters in the front-to-rear direction when in use, and about 2 mm in the front-to-rear direction in this embodiment.

[0030] When an earthquake causes the structural bodies 3 and 4 to shake left and right and the joint section 2 to narrow, as shown in Figure 8, the supporting joint plate 7 and the supported joint plate 8 climb up the climbing slope 11 of the second joint plate support section 6 to absorb the shaking caused by the earthquake.

[0031] When an earthquake causes the structural bodies 3 and 4 to shake left and right and the joint section 2 becomes wider, as shown in Figure 9, the supporting joint plate 7 and the supported joint plate 8 slide left and right on the second joint plate support section 6, absorbing the shaking caused by the earthquake. [Industrial Applicability]

[0032] The present invention finds application in the floor jointing equipment manufacturing industry. [Explanation of symbols]
