Description

[Technical field]

[0001] The present invention relates to a joint device for sealing a joint between wall surfaces of one and another building structure. [Background technology]

[0002] A known conventional joint device is, for example, "a wall joint cover device comprising at least two or more telescopic link mechanisms having three central pivot parts in the center, both ends of which are pivotally supported on the outer wall surfaces of the left and right buildings on the side of the joint, the central pivot parts on both sides of these telescopic link mechanisms, U-shaped cover plates that open on the left and right building sides and are pivoted by pivot pins fixed to the center of the inner plate, end cover plates pivoted to the pivot parts at both ends of the telescopic link mechanisms and whose tip parts are inserted inside by sliding to contact the outer plate of the cover plate, and a central cover plate whose both ends pivoted to the central pivot part at the center of the telescopic link mechanism overlap with the outer plate of the cover plate and can slide" (Patent Document 1).

[0003] However, with this type of joint device, for example, if the dimensions of the joint portion become large in the vertical direction and the length covered by a cover plate or the like becomes long in the vertical direction, the impact of strong winds, etc. becomes greater, causing the cover plate or the bar-shaped mounting member that attaches the cover plate to bend.

[0004] One solution to this problem is known in the art as follows: "A joint device for closing a joint between one and the other structural members in the left-right direction, the joint device including: a plurality of telescopic link mechanisms, one end of which is attached to one of the structural members and the other end of which is attached to the other structural member, and each of which has a plurality of attachment parts; a plurality of bar-shaped mounting members extending in the vertical direction and attached to the attachment parts; a plurality of joint covers, one end of which is fixed to each of the plurality of mounting members and which close the joint parts; and a reinforcing member attached to at least one of the plurality of mounting members and passing through a reinforcing member passing part provided on the mounting member, the attachment part of the telescopic link mechanism being provided in a position where it does not move in the vertical direction even when the telescopic link mechanism is telescopically extended; and the reinforcing member passes through the reinforcing member passing part of at least one of the mounting members, preventing deflection" (Patent Document 2).

[0005] With this type of joint device, the joint cover and mounting members can withstand the load of strong winds and the like without bending, but if an earthquake causes the left and right bodies to sway so that the joint area narrows, the telescopic link mechanism will extend in the vertical direction, which means that the distance between the upper and lower telescopic link mechanisms must be increased, making construction impossible at some construction sites.

[0006] [Patent Document 1] JP 2015-1111 A [Patent Document 2] Patent No. 6934687 Summary of the Invention [Problem to be solved by the invention]

[0007] In view of the above-mentioned conventional drawbacks, the present invention aims to provide a joint device which can be installed even in places where large dimensions cannot be secured in the vertical direction, and in which the joint cover and mounting members can withstand the load of strong winds and the like without bending, and which can absorb shaking caused by earthquakes, etc.

[0008] 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. 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]

[0009] In order to achieve the above object, the joint device described in claim 1 of the present invention is a joint device for closing a joint between one structure and another structure, and includes a plurality of mounting parts, one end side of which is attached to the one structure, and the other end side of which is attached to the other structure, and a plurality of telescopic link mechanisms provided at a predetermined interval in the vertical direction, a plurality of bar-shaped mounting members extending in the vertical direction and attached to each of the mounting parts, and a plurality of joint covers, one end of which is attached to each of the plurality of mounting members and closing the joint, characterized in that the telescopic link mechanism is composed of a plurality of link materials combined in an approximately lattice pattern, connection means for connecting at least some of the link materials and the bar-shaped mounting members so as to be slidable in the vertical direction, and the mounting part provided in a position that does not move in the vertical direction even when the telescopic link mechanism expands and contracts.

[0010] The connection means of the joint device described in claim 2 is characterized by being composed of a sliding member provided near one end of the link material and a sliding portion provided on the mounting member. 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, the link materials form numerous lattices and are formed horizontally overall. Therefore, even if the joint portion becomes narrow, the vertical dimension does not become relatively large, and the system can be installed in various locations. (2) At least some of the link members are provided with connecting means for vertically slidably connecting the bar-shaped mounting members at the left and right ends, so that the mounting members are supported at multiple points by the link members. Therefore, even if the dimensions of the joints are large, deflection of the joint covers and mounting members due to strong winds, etc. can be prevented. (2) In the invention described in claim 2, the same effect as in (1) above can be obtained and the shaking caused by an earthquake can be smoothly absorbed. [Brief description of the drawings]

[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 (horizontal 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] The present invention can be used for buildings, civil engineering structures, floors, exterior walls, vehicle couplings, and the like.

[0015] In the first form for implementing the present invention shown in Figures 1 to 8, in this embodiment, 1 is a joint device installed between left and right structures 3, 4 (in this embodiment, the left structure is one structure 3, and the right structure is the other structure 4) arranged via a joint portion 2.

[0016] In this embodiment, it is used to close a vertical joint 2 between a wall surface of one body 3 and a wall surface of the other body 4.

[0017] As shown in Figures 1 and 2, for example, this joint device 1 has a plurality of mounting portions 6, one end of which is attached to one body 3 via a hinge member 5, and the other end of which is attached to the other body 4 via a hinge member 5, and is composed of an expandable link mechanism 7 having a plurality of mounting portions 6 and arranged at a predetermined interval in the vertical direction, a plurality of bar-shaped mounting members 8 extending in the vertical direction and attached to each of the mounting portions 6, and a plurality of joint covers 9, one end of which is attached to each of the plurality of mounting members 8 and which cover the joint portions.

[0018] 3 to 5, the telescopic link mechanism 7 is composed of a plurality of link members 10 combined horizontally in a generally lattice shape, connection means 11 connected to at least some of the link members 10 and the bar-shaped mounting member 8 so as to be slidable in the vertical direction, and the mounting part 6 provided on a pivot part 12 that does not move in the vertical direction even when the telescopic link mechanism 7 expands and contracts, and a plurality of telescopic link mechanisms (two in this embodiment) are provided at a predetermined interval in the vertical direction of the joint part 2. Note that two or more telescopic link mechanisms 7 may be provided.

[0019] This telescopic link mechanism 7 has a pivot part 12 located at a position approximately horizontal to the mounting parts 6 provided on the left and right hinge members 5, and a mounting member 8 is attached to this mounting part 6 by a pivot or the like, and one end of a joint cover 9 is fixed to the mounting member 8. In the normal state, the multiple links 10 are connected in a generally lattice pattern, crossing at an angle, and the crossing portions of the links 10, excluding the mounting portion 6, are connected by connection pins 10a.

[0020] The link members 10 are bar-shaped members, and among the plurality of link members 10, some of the link members 10 on the left and right body 3, 4 sides have their tip portions (one end portion) extended and are connected to a mounting member 8 at the end portion on one body 3 side or the other body 4 side via a connecting means 11 so as to be slidable in the vertical direction. In this embodiment, the four link members 10 at the left and right ends are formed to extend toward the left and right body sides, and their tip portions are connected to a mounting member 8 attached to a mounting portion 6 near the end portion of the telescopic link mechanism 7 via a connecting means 11. The mounting portion 6 near the end portion of the telescopic link mechanism 7 can also be called an end pivot portion 7a (see FIG. 1).

[0021] Specifically, one end of a total of four link materials 10 forming a single large diamond-shaped opening on one side of the body is extended toward one of the bodies, and one ends of the four link materials 10 are connected via connecting means 11 to a bar-shaped mounting member 8 extending in the vertical direction attached to the mounting portion (end pivot portion 7a) 6 at the end of the telescopic link mechanism 7, while the other end of a total of four link materials 10 forming a single large diamond-shaped opening on the other body is extended toward the other body, and one ends of the four link materials 10 are connected via connecting means 11 to a bar-shaped mounting member 8 extending in the vertical direction attached to the mounting portion (end pivot portion 7a) 6 near the end of the telescopic link mechanism 7.

[0022] In this embodiment, one end of the link material 10 is extended to provide a connecting means 11, but a bar member or the like separate from the link material 10 may be fixed to one end of the link material 10 and connected by the connecting means 11.

[0023] In this embodiment, the connection means 11 is composed of a roller-shaped sliding member 13 provided near one end of the link material 10 and a rail-shaped sliding portion 14 formed or provided on the mounting member 8, to which the sliding member 13 is connected by engagement or the like.

[0024] In this embodiment, rail-shaped sliding parts 14 having a roughly U-shaped cross section are fixed to the mounting members 8 at the left and right ends. When using mounting members 8 in the shape of a cylinder, round pipe, square pipe, square column, hat steel, or the like, a rail member can be fixed to the mounting member 8 as in this embodiment to serve as the sliding part 14. However, when using a bar member having a roughly U-shaped cross section, H-shaped steel, or lip channel steel as the mounting member 8, the internal space of this mounting member 8 may serve as the sliding part 14.

[0025] In this way, by connecting the tip of the link material 10 to the mounting member 8 via a pair of left and right connecting means 11 closest to the wall surfaces of the left and right bodies 3, 4, the telescopic link mechanism 7 is connected to the bar-shaped mounting member 8 not only through the mounting portion 6 but also through the connecting means 11, thereby improving the rigidity of the telescopic link mechanism 7 and the mounting member 8 and preventing twisting of the telescopic link mechanism 7, mounting member 8, joint cover 9, etc., even in strong winds, etc.

[0026] In a preferred embodiment, the mounting portions 6 are provided at locations that do not move in the vertical direction even when the telescopic link mechanism 7 extends and retracts in the left-right direction, and are formed so as to be positioned approximately on a horizontal line connecting the centers of the hinge members 5.

[0027] This mounting portion 6 is provided at the location where the link materials 10 intersect, and is formed at a location (approximately the center of the telescopic link mechanism 7 in the vertical direction) that does not move vertically even when the telescopic link mechanism 7 telescopes in the left-right direction as described above.

[0028] The link material 10 used is in the shape of a square column or square pipe, but any cross-sectional shape such as a U-shape or H-beam shape can be used as long as it is in the shape of a bar.

[0029] A plurality of bar-shaped mounting members 8 are attached to the mounting portion 6 via mounting fixtures 15, respectively.

[0030] This mounting tool 15 is composed of an attachment portion 16 consisting of, for example, a bolt 16a and a nut 16b that is attached to the mounting portion 6, a mounting tool main body 17 that is fixed to the attachment portion 16, has a predetermined length in the vertical direction, and has side wall portions 17a that roughly clamp both side surfaces of the mounting member 8, and a fixing pin 18 that penetrates the side wall portions 17a and the mounting member 8 to integrate them during installation.

[0031] In this embodiment, the mounting member 8 is a bar-shaped member (vertical beam member) that is shaped like a square tube or a square column and extends in the vertical direction, and is attached in a substantially vertical state to each of the mounting parts 6 of the telescopic link mechanism 7, which are provided in a plurality of vertical directions, via mounting fixtures 15. The end pivot part 7a of the telescopic link mechanism 7 to which the hinge member 5 is connected not only connects the hinge member 5 but also has a function as the mounting part 6, and the mounting member 8 is attached to this end pivot part 7a as well. The shape of the mounting member 8 may be a columnar shape or a round pipe shape, and may be any shape such as H-shaped steel, lip channel steel, hat steel, etc.

[0032] In this embodiment, the joint cover 9 is a plate material that extends in the vertical direction and has a generally crank shape in cross section, and one end of the joint cover 9 is fixed to the mounting member 8.

[0033] The joint covers 9 are attached to the multiple mounting members 8, and adjacent joint covers 9 overlap to cover the joints 2. The joint covers 9 located at the left and right ends may be formed, for example, in a U-shape so as not to protrude toward the frameworks 3 and 4. It is also desirable to fill the gap between the joint covers 9 and the frameworks 3 and 4 with a sealant or the like.

[0034] If the left and right frames 3, 4 shake due to an earthquake or other event so that the joints narrow, the expandable link mechanism 7 contracts in the left-right direction as shown in Figure 6, and the overlap width between adjacent joint covers 9 increases, absorbing the shaking caused by the earthquake.

[0035] If the left and right frames 3, 4 shake due to an earthquake or other event, widening the joints, the telescopic link mechanism 7 extends left and right as shown in Figure 7, and the overlap width between adjacent joint covers 9 becomes smaller, absorbing the shaking caused by the earthquake. Although not shown, if the left and right frames 3, 4 sway in different forward and backward directions due to an earthquake or the like, the telescopic link mechanism 7 rotates in the forward and backward directions around the hinge member 5 as a fulcrum to absorb the swaying movement caused by the earthquake.

[0036] In the embodiment of the present invention, the telescopic link mechanism has been described as having both ends attached to the left and right bodies so that they can rotate in the front-to-back and up-to-down directions. However, if the left and right bodies do not swing in the front-to-back direction or the like due to an earthquake, both ends may be fixedly attached without using hinge members or the like.

[0037] In addition, although the joint covers used are approximately angle-shaped, for example, the joint cover located in the center in the left-right direction may be approximately T-shaped in cross section, and the other joint covers may be approximately angle-shaped, or joint covers of other shapes may be used.

[0038] Furthermore, in the embodiment of the present invention, the case has been described where the device is used as a wall joint device for sealing joints between wall surfaces, but it may also be used to seal joints between floor surfaces or ceilings, for example.

[0039] In the embodiment of the present invention, the connecting means is composed of a roller-shaped sliding member and a rail-shaped sliding portion. However, for example, a pin or the like may be fixed to the tip of the link material near the left and right ends, and a long hole may be formed in the mounting member so that this pin can be connected so as to be slidable in the up and down direction.
