Description

[Technical field]

[0001] The present invention relates to a joint cover device that covers a joint between left and right structural members provided with a joint therebetween. [Background technology]

[0002] Conventionally, as a joint cover device that mainly covers a joint between the wall surfaces of one building frame and the other building frame, there has been proposed a joint cover device that includes "at least two pairs of hinge members provided at a predetermined distance on the left and right wall surfaces on the open end side of the joint of left and right buildings erected through the joint, a link extension arm mechanism that is fixed to the movable member of the other hinge member of the at least two pairs of hinge members and protrudes rearward from the open end, and a link extension arm mechanism that is pivotally supported at one end by the movable member of one of the at least two pairs of hinge members and the other end by the link extension arm mechanism. A "wall joint device" is known, which is characterized by comprising at least two or more telescopic link devices that are extendable and have a plurality of equally spaced central pivot parts pivotally supported on a telescopic arm mechanism, and a plurality of approximately angle-shaped joint covers that are pivotally supported on the plurality of central pivot parts of the at least two or more telescopic link devices and on the pivot part of the link telescopic arm mechanism, with support parts on the link telescopic arm mechanism side that are successively higher and have cover parts that overlap at a location that is approximately half the dimension between the central pivot parts (Patent Document 1).

[0003] This type of wall joint device is capable of absorbing shaking caused by earthquakes so that gaps do not form in the joints. However, because the joints are sealed using multiple joint covers, rainwater, sound, fire, etc. can pass through the tiny gaps between the multiple joint covers, and this device alone is unable to provide sufficient soundproofing or fireproofing effects.

[0004] [Patent Document 1] JP 2012-233368 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 joint cover device that can completely seal joints to prevent rainwater, etc. from passing through, 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 joint cover device according to claim 1 of the present invention is a joint cover device for closing a joint between one frame and another frame, and is configured with a plurality of telescopic link mechanisms having one end rotatably attached to the one frame in the front-rear direction and the other end rotatably attached to the other frame in the front-rear direction, and having a plurality of pivot parts, a plurality of mounting members respectively attached to the pivot parts of the telescopic link mechanisms, a sheet-like joint cover attached to the mounting members and made of a soft material for closing the joint part, and a mounting fixture for mounting the joint cover to the mounting members, and when the left-right width of the joint part changes due to an earthquake, the left-right cover width attached to each of the plurality of mounting members of the joint cover also changes in response to the change. The mounting member is composed of a connection part connected to the pivot part and a bent part formed on a protruding end side protruding outward from the connection part, and the joint cover is attached in a slack state toward the connection part along the bend of the bent part. It is characterized by:

[0009]

[0010] Claim 2 The bent portion of the joint cover device described in is formed in a generally mountain shape, and the mounting fixture is characterized in that it clamps the joint cover to the bent portion. Effect 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 sheet-like joint cover made of a soft material that seals the joints is used, and when the width between the left and right sides of the joints changes due to an earthquake, the width of the left and right covers attached to each of the joint cover's multiple mounting members also changes in response to the change. This allows the joint cover to absorb the shaking without being damaged and to seal the joints without any gaps. Therefore, it is possible to obtain waterproofing, soundproofing, fireproofing, etc., and also to absorb vibrations during an earthquake without being damaged. (2) A bent portion is formed in the mounting member, and the joint cover is attached in a sagging state toward the connection portion along the bend of the bent portion. Since the joint cover and the bent portion of the mounting member are attached in a state of approximate surface contact, it is possible to more effectively obtain waterproofing, soundproofing, fireproofing, etc. (3) Claim 2 The invention described above can obtain the same effects as those described in (1) and (2) above, and since the joint cover is attached in a clamped state to the bent portion, it can obtain even more effective waterproofing, soundproofing, fireproofing, etc. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0013] The present invention will be described in detail below with reference to the embodiments shown in the drawings. In this specification, the left-right direction, the top (top of the drawing) and the bottom (bottom of the drawing) directions are based on Fig. 1. The front (bottom of the drawing) and rear (top of the drawing) directions are based on Fig. 2.

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

[0015] In a first embodiment for carrying out the present invention shown in Figs. 1 to 6, reference numeral 1 denotes a joint covering device for covering a joint 2 between one body 3 and another body 4.

[0016] As shown in Figures 1 and 2, this joint device 1 is configured with a plurality of telescopic link mechanisms 6 having one end rotatably mounted in the front-rear direction on one of the frames 3 and the other end rotatably mounted in the front-rear direction on the other frame 4, and having a plurality of pivot parts 5, a plurality of mounting members 7 attached respectively to the pivot parts 5 of the telescopic link mechanisms 6, a sheet-like joint cover 8 formed of a soft material that is attached to the plurality of mounting members 7 and covers the joint portion 2, and a plurality of mounting fixtures 9 that are attached to the front end side of each of the plurality of mounting members 7 in a state where they clamp the cover width between the left and right sides of the joint cover 8 (see Figure 2, for example).

[0017] The telescopic link mechanism 6 can be any known telescopic link mechanism 6 having multiple pivot points 5, but in this embodiment, a substantially triangular telescopic link mechanism 6a and a pantograph-shaped telescopic link mechanism 6b are used. By using multiple types of telescopic link mechanisms 6 in this way, the load applied to the joint cover 8 due to strong winds, etc. can be efficiently distributed. These telescopic link mechanisms 6 are attached rotatably in the front-rear direction via hinge members.

[0018] Furthermore, in this embodiment, one end portion is attached to one of the frames and the other end portion is attached to the other frame, and the telescopic arm mechanism 10 is further provided which is connected to at least one of the mounting members 7. The telescopic arm mechanism 10 is composed of one arm member 12 having one end attached to the one frame 3 and the other end inserted into a case-shaped support member 11, the other arm member 13 having one end attached to the other frame 4 and the other end inserted into the support member 11, and the support member 11 connected to at least one of the mounting members 7, which in this embodiment is located approximately in the center of the joint portion 2, and having through-hole-shaped arm insertion holes into which the one arm member 12 and the other arm member 13 are inserted. Similar to the telescopic link mechanism 6, the telescopic link mechanism 10 is attached rotatably in the front-rear direction via a hinge member.

[0019] The load can be further distributed by providing such an extendable arm mechanism 10. When connecting multiple mounting members 7 and support members 11, it is advisable to connect them via rails or the like so as not to impede the sliding of the mounting members 7 in the left-right direction.

[0020] In this embodiment, the mounting member 7 is composed of a connection portion 14 on the rear end side that is attached to the pivot portion 5 of the telescopic link mechanism 6, and a bent portion 15 on the front end side that protrudes outward from the connection portion 14.

[0021] 3, the mounting member 7 is formed by bending or welding a plate-like member, and in this embodiment, the connection portion 14 is formed in a generally U-shape when viewed obliquely, and this portion is pivotally supported to the pivot portion 5 of the telescopic link mechanism 6 by a bolt or the like. The bent portion 15 is formed in a generally mountain-like shape when viewed obliquely, protruding outward (toward the front), and the mounting member 7 as a whole is formed in a shape similar to a lip channel steel when viewed from above. The mounting fixture 9 is attached to the bent portion 15 by a screw or the like.

[0022] In this embodiment, the fixture 9 is formed in a mountain shape that is in approximate surface contact with the bent portion 15 and extends in the vertical direction. After the joint cover 8 is placed on the bent portion 15, the fixture 9 is attached with a screw or the like so that the inner surface of the fixture 9 is in approximate surface contact with the bent portion 15, and the joint cover is fixed to the bent portion 15 in a clamped state. By attaching in this manner, the joint cover 8 comes into surface contact with the mounting member 7 and the fixture 9, and can cover the joint portion 2 to close it. When a fireproof sheet, soundproof sheet, or waterproof sheet is used as the joint cover 8, by attaching in this manner, it is possible to reliably prevent fire, sound, water, and the like from entering the inside of the joint portion 2 (the rear side of the drawing).

[0023] The joint cover 8 is a sheet-like member formed of a flexible or stretchable soft material, and may be, for example, a rubber sheet, a fireproof sheet, a soundproof sheet, a metal sheet such as lead, a waterproof sheet, or the like, and in this embodiment, a rubber sheet is used as the joint cover 8. These sheets may be used in combination.

[0024] In the normal state (as shown in FIG. 1), this joint cover 8 is attached in such a manner that it can absorb the shaking movement without being damaged if the width of the joint 2 changes due to an earthquake. Specifically, the joint cover 8 is attached in a sagging state toward the connection part 14 of the mounting member 7 along the bend of the bend part 15, and the degree of sagging is determined so that the joint cover 8 is attached to a length that will not cause damage even if the joint 2 becomes its widest due to an earthquake.

[0025] In addition, if the joint cover 8 is formed of an elastic rubber sheet or the like, as long as the joint cover 8 can stretch to accommodate the increase in width of the joint 2, even if the joint cover 8 is not attached in a sagging state toward the connection part 14 of the mounting member 7, it is included in the form that can absorb the shaking movement without damage when the width of the joint changes due to an earthquake.

[0026] In addition, it is desirable that the left and right ends of the joint cover 8 are fixed in close contact with the wall surfaces of the left and right structures 3, 4 so that no gaps are created between them, but a sealant or the like may be filled between the joint cover 8 and the wall surfaces of the left and right structures 3, 4.

[0027] When the left and right frames 3, 4 shake during an earthquake so that the joint portion 2 narrows, as shown in FIG. 5, the telescopic link mechanism 6 and the telescopic arm mechanism 10 contract in the left-right direction, and the cover width between the left and right sides attached to the multiple mounting members of the joint cover changes so as to narrow, and the joint cover 8 sags significantly toward the connection portion 14 of the mounting member 7, absorbing the shaking caused by the earthquake.

[0028] When the left and right frames 3, 4 shake during an earthquake so that the joint portion 2 widens, as shown in Figure 6, the left and right cover width attached to the multiple mounting members of the joint cover changes to wider, the telescopic link mechanism 6 and the telescopic arm mechanism 10 extend in the left and right directions, and the sagging of the joint cover 8 is almost eliminated, absorbing the shaking caused by the earthquake.

[0029] [Different modes for carrying out the invention] Next, different embodiments for carrying out the present invention will be described with reference to Figures 7 to 9. In describing these different embodiments for carrying out the present invention, the same components as those in the first embodiment for carrying out the present invention are designated by the same reference numerals, and duplicated descriptions will be omitted.

[0030] In the second form for carrying out the present invention shown in Figures 7 to 9, the main difference from the first form for carrying out the present invention is that, for example, taking Figure 9 as a reference, the front end side of the mounting member 7A is formed into a curved bent portion 15A, and the shape of the mounting member 7A is also changed to a mounting fixture 9A having a curved inner surface that fits the curvature of the bent portion 15A or that comes into approximate surface contact with the front surface of the bent portion 15A. Therefore, even with a joint cover device using such a mounting member 7A, the same effect as in the first embodiment of the present invention can be obtained.

[0031] In the embodiment of the present invention, an attachment member is described that fixes the joint cover in a clamped state to the bent portion, but a bar-shaped member such as a square column, square pipe, round bar or round pipe may also be used as the attachment member.

[0032] In addition, when attaching the joint cover to the mounting member, a mounting fixture is used to clamp the joint cover, but a screw or the like may be used as the mounting fixture and the joint cover may be fixed directly to the mounting member using the screw or the like.

[0033] Furthermore, in the embodiment of the present invention, the joint covering device of the present invention is used to cover the joints between wall surfaces, but the joint covering device of the present invention may also be used as a device to cover the joints between ceilings. [Industrial Applicability]

[0034] The present invention finds application in the industry which manufactures joint covering devices. [Explanation of symbols]
