Description

  The present invention relates to a connecting member for connecting structural members constituting a structure such as a building with a wire, and more particularly to a connecting member for a structural member for connecting eaves members arranged at a predetermined interval to the structure.

  In recent structures, an example in which a large number of glass plates are supported without using a sash and an outer wall is constructed using these glass plates is increasing (for example, Non-Patent Document 1). The construction method of Non-Patent Document 1 secures the rigidity of the glass wall surface by sandwiching each corner portion of four adjacent face glasses by support members and connecting these support members to a cross-shaped cable. Is.

This construction method is a construction method in which the outer wall is constructed with a glass plate, but recently, the framework of the building is constructed in a dome shape, and a large number of glass plates are supported by this framework to give the whole building a sense of transparency. The number of such dome-shaped buildings is increasing (for example, Non-Patent Document 2). The framework of Non-Patent Document 2 is a truss or ramen structure made of steel, but the dome-shaped structure framework can be obtained by arranging the eave members formed in a ring shape at predetermined intervals in the vertical direction. It can also be constructed. In this case, it is necessary to secure the rigidity of the structure by connecting the upper and lower flange members adjacent to each other by the connecting member.

  As described above, when a frame of a dome-shaped structure is constructed using a ring-shaped flange member, a connecting member that connects the vertically adjacent flange members becomes important. When a wire rod such as a rod is used as the connecting member, both ends of the wire rod are connected to the connecting portion provided on the rod member. However, the rod member positioned up and down due to an assembly error of the rod member. When the positions of the respective connecting portions are shifted, there is a problem that the flange members cannot be connected by the wire. In addition, there is a possibility that local stress is generated when the flange member is displaced later.

  The present invention is intended to solve the problems of the connecting member of the conventional structural member, and even if a mounting error or the like occurs in the structural member constituting the structural member such as the eaves member, local stress is generated. An object of the present invention is to provide a connecting member for a structural member that can connect the structural members without problems.

In order to achieve the above object, the present invention is a structural member arranged at a predetermined interval in a structure, and is formed on the structural member in a structural member that connects adjacent structural members. A spherical bearing is attached to the hole, a sphere supported by the spherical bearing, and a spherical hole in which the sphere portion is supported in the sphere, thereby forming the spherical bearing, the sphere, and the sphere. parts and the double spherical rotating body substantially to match the rotation center consisting of the spherical hole is provided in the hole of the structural member, and the provided structural member adjacent one side sphere, on the other side structure There is provided a connecting member for a structural member, characterized in that the spherical body portion provided on the member is connected by a wire.

  According to the present invention, even if a deviation occurs in the position of each hole of the adjacent structural member due to the mounting error of the structural member constituting the structure such as the eaves member or the beam member, that is, the continuously arranged wire rod Even if it cannot be arranged in a straight line, the deviation is absorbed by the follow-up operation of the double spherical rotating body, so that adjacent structural members can be connected without any problem. Further, the wire can be easily inclined at an inclination angle along, for example, a dome shape by the following operation of the double spherical rotating body. Furthermore, even when a displacement occurs in the structural member later, the displacement can be absorbed by the follow-up operation of the double spherical rotating body.

According to the present invention, since the wire rod and the sphere are screw-connected, the tension of the wire rod can be adjusted by adjusting the screwing amount.

  According to the connecting member of the structural member according to the present invention, the double spherical rotating body having the rotation center substantially coincided with the hole formed in the structural member is provided, and one of the adjacent structural members provided on the one side is provided. Since the spherical rotating body and the other spherical rotating body provided on the other structural member are connected by a wire rod, local stress is not generated even if a mounting error occurs in the structural member. The structural members can be connected to each other without any problem.

  Hereinafter, preferred embodiments of a connecting member of a structural member according to the present invention will be described in detail with reference to the accompanying drawings.

The upper end portion of the net member 20 is arranged so that the trajectory connecting the ends of the cables 18, 18... Has a substantially circular shape, and the column is erected at the center of the structure 10 shown in FIGS. The lower end portion of the net member 20 is fixed so as to have a substantially circular shape connecting the ends of the cables 18, 18... And embedded in the structure base portion 24 shown in FIG. The anchor portion is fixed via a tension adjusting member (not shown). By pulling the cable 18 through the tension adjusting member or the connecting member 30 (FIG. 6) described later, a predetermined tension is applied and adjusted to each cable 18, 18... Of the net member 20, and the cables 18, 18. 2 are fixed to the intersecting portions via connecting members 30 shown in FIGS. 4 to 6.

  As shown in FIG. 6, the connecting member 30 for connecting the ring-shaped scissors member 16 to the intersection of the cables 18 and 18 includes a receiving member 34 in which four screw rods 32, 32. 36, a second clamp member 38, a third clamp member 40, and the like.

  The receiving member 34 is a fixing means such as screwing or welding so that the screw rods 32, 32... Are horizontal in the notch 17 formed in the inner peripheral portion of the flat ring-shaped flange member 16 having a predetermined width. It is fixed by. Note that the shape of the ring-shaped scissors member 16 is not limited to a flat plate shape, and may be a columnar shape, for example.

  As shown in FIG. 5, the first clamp member 36 has a groove 42 into which one cable 18A is fitted, and four holes 44, 44... Into which the screw rods 32, 32. Has been. In addition, the second clamp member 38 has a groove 46 into which the other cable 18B is fitted, and four holes 48, 48... Into which the screw rods 32, 32. Yes. Further, the third clamp member 40 is disposed between the first clamp member 36 and the second clamp member 38, and one cable 18 </ b> A is routed by the groove 42 of the first clamp member 36 on one side thereof. A groove 50 for clamping is formed, and a groove 52 for clamping the other cable 18B is formed by the groove 46 of the second clamp member 38 on the other surface. Further, the third clamp member 40 is formed with four holes 54, 54... Into which the screw rods 32, 32.

  A procedure for connecting the ring-shaped flange member 16 and the cable 18 by the connecting member 30 will be described. First, the screw rods 32, 32... Are passed through the holes 44, 44... Of the first clamp member 36, and the first clamp member 36 is attached to the receiving member 34 side. Next, one cable 18 </ b> A is fitted into the groove 42 of the first clamp member 36. Next, the screw rods 32, 32... Are passed through the holes 54, 54... Of the third clamp member 40, the third clamp member 40 is attached to the receiving member 34 side, and the groove 50 of the third clamp member 40 is inserted into one of the holes. After fitting into the cable 18A, the other cable 18B is fitted into the groove 52 of the third clamp member 40.

  Next, the screw rods 32, 32... Are passed through the holes 48, 48... Of the second clamp member 38, and the other cable 18B is fitted into the groove 46 of the second clamp member 38. Next, nuts 58 are screwed into the four screw rods 32, 32... Projecting outward from the second clamp member 38 through the washers 56, and the nuts 58 are tightened. Thereby, the ring-shaped eaves member 16 is fixed at the intersection of one cable 18A and the other cable 18B.

  By the way, since the structure 10 of the embodiment is formed in a dome shape, it is necessary to obliquely install the cables 18 and 18 with an inclination angle along the dome shape with respect to the vertical direction. Therefore, in order to adjust the inclination angle and tension of the cables 18, 18, the connecting member 30 has semicircular spacers 60, 60... Between the receiving member 34 and the first clamp member 36 as shown in FIG. Intervene. Grooves 62, 62, 62 for allowing the screw rod 32 to escape are formed in the spacer 60. The first clamp member 36 is separated from the receiving member 34 by interposing a predetermined number of spacers 60, 60... So as to sandwich the screw rods 32, 32. As a result, the substantial connection positions of the cables 18A and 18B are shifted in the horizontal direction. Therefore, the cable connection positions of the cables 18A and 18B can be adjusted by appropriately adjusting the cable connection positions in the ring-shaped flange members 16, 16. The tilt angle and tension can be adjusted.

  In addition, as shown in FIG. 7, the connecting member 30 has an angle with respect to the direction in which the cable 18A is disposed, so that both ends 64 of the cable fitting tubular portion formed by abutting the groove 42 and the groove 50 of the clamp members 36 and 40 with each other. In contrast, it has a conical shape with a margin. Accordingly, it is possible to prevent the cable 18A from having a problem in which the inclination angle is regulated by the both end portions 64 or worn by contact. Both ends of the cable fitting tubular portion formed by abutting the groove 46 and the groove 52 of the clamp members 38 and 40 are also formed in a conical shape.

  In the connection structure between the cable 18 and the ring-shaped flange member 16 according to the embodiment, as shown in FIG. 8, the ring-shaped flange member 16 is connected to the cables 18A and 18B at the intersection of the cables 18A and 18B. Is not to be done. For example, the ring-shaped eaves member 16 may be fixed at a position other than the crossing position of the cables 18A and 18B as shown in FIG. 9, and the cables 18, 18... Are arranged vertically and horizontally as shown in FIG. , 18... And the ring-shaped flange member 16 may be connected to the cables 18, 18. According to the connection structure of FIGS. 8 to 10, it is possible to obtain a shape effect that hardly deforms even when an external force such as wind pressure is applied to the structure.

  The glass plates 12 and 12 supported by the structure 10 are integrally supported by the ring-shaped flange member 16 of the structure 10 at the four corners by the support member 70 of the point support structure shown in FIG. That is, the vertical spacing between the ring-shaped flange members 16, 16... Is substantially equal to the height dimension of the glass plate 12, and the upper side of the glass plate 12 positioned between the ring-shaped flange members 16, 16 adjacent vertically. The corner is supported by support members 70 and 70 attached to the lower surface of the ring-shaped scissors member 16 located on the upper side of the ring-shaped scissors members 16 and 16, and the corner of the lower side of the glass plate 12 is It is supported by support members 70 and 70 attached to the upper surface of the ring-shaped saddle member 16 located on the lower side.

  Moreover, the glass plate support structure of embodiment is the front-back direction of the glass plate 12 surface so that a part of both right-and-left side parts of the glass plates 12, 12 ... adjacent to the horizontal direction may overlap (overlap). The two glass plates 12 and 12 are arranged to face each other with a predetermined distance therebetween, and the respective corners of the two overlapping glass plates 12 and 12 are supported by one support member 70.

  As shown in FIGS. 11 and 12, the support member 70 includes four rod-shaped members 72, 74, 76, 78, bearings 80, 82, and the like. In FIG. 12, the right end portion of the rod-shaped member 72 is attached to a bearing portion 84 projecting from the ring-shaped flange member 16 via a pin 86 so as to be swingable in the vertical direction. Further, a screw hole 88 is formed coaxially with the rod-shaped member 72 at the left end portion of the rod-shaped member 72, and a male screw portion 90 formed at the right end portion of the rod-shaped member 74 is screwed into the screw hole 88. ing. Thereby, the rod-shaped member 74 is connected to the rod-shaped member 72 so as to be stretchable. The bearing portion 84 protrudes from the ring-shaped flange member 16 via a pin 83 so as to be rotatable in the horizontal direction.

  The configuration that allows the bearing portion 84 to rotate in the horizontal direction is not limited to this, and a cover member that provides a convex portion at the end of the bearing portion 84 and covers the convex portion to rotatably support the bearing portion 84. May be provided.

  A sphere 92 is formed at the left end of the rod-shaped member 74, and the sphere 92 is fitted to the bearing 80 so as to be rotatable, swingable, and swingable. The bearing 80 is fixed to a hole 13 formed in advance on the glass plate 12 on the indoor side, and is divided into two parts in consideration of ease of attachment to the hole 13.

  A spherical cavity portion 94 is formed inside the spherical body 92 of the rod-shaped member 74, and the spherical body 96 is rotatably fitted in the cavity portion 94. In addition, a screw hole 98 is formed in the sphere 96, and a male screw portion 100 formed at the right end portion of the rod-shaped member 76 is screwed into the screw hole 98 through the sphere opening 102. As a result, the rod-shaped member 76 is connected to the rod-shaped member 74 so as to be freely extendable, pivotable, swingable, and swingable.

  A screw hole 104 is formed at the left end portion of the rod-shaped member 76, and a male screw portion 106 formed at the right end portion of the rod-shaped member 78 is screwed into the screw hole 104. Thereby, the rod-shaped member 78 is connected to the rod-shaped member 76 so as to be extendable and contractible. A spherical body 108 is formed at the left end of the rod-shaped member 78, and the spherical body 108 is connected to a bearing 82 so as to be rotatable, swingable, and swingable. The bearing 82 is fixed to the hole 13 formed in advance on the glass plate 12 on the outdoor side.

  According to the support member 70 configured in this manner, the rod-shaped member 72 is horizontally and vertically moved by the action of the pins 83 and 86 in the case of the indoor glass plate 12 with respect to the holes 13 of the glass plate 12 processed in advance. Since the position of the sphere 92 of the rod-shaped member 74 can be adjusted in a three-dimensional direction by being able to swing up and down and the rod-shaped member 74 being telescopic with respect to the rod-shaped member 72, Even if the hole 13 of the glass plate 12 is displaced from the specified position, that is, when an attachment error occurs, the sphere 92 of the rod-shaped member 74 can be connected to the bearing 80 of the hole 13.

  Further, in the case of the outdoor glass plate 12, the rod-shaped member 76 is swingable by the action of the sphere 96 and can be expanded and contracted with respect to the rod-shaped member 74, and the rod-shaped member 78 is rod-shaped. Since the position of the sphere 108 of the rod-shaped member 78 can be adjusted in a three-dimensional direction by being able to expand and contract with respect to the member 76, even if the hole 13 of the glass plate 12 on the outdoor side is displaced from the specified position, that is, Even when an attachment error occurs, the sphere 108 of the rod-shaped member 78 can be connected to the bearing 82 of the hole 13.

  Thereby, even when the glass plate 12 on the indoor side and the glass plate 12 on the outdoor side are not parallel or when an attachment error occurs, both the glass plates 12 and 12 can be easily joined by the single support member 70. It is possible to cope with various glass arrangements. Further, since attachment errors are absorbed at the time of joining, the generation of local stress can be prevented, and the strength performance can be improved. Further, even when the positional deviation occurs later, the positional deviation can be freely followed and absorbed. Furthermore, since bending does not occur in the rod-shaped members 72, 74, 76, and 78 at the time of absorption, the rod-shaped members 72, 74, 76, and 78 do not need to have excessive strength and can be made relatively thin. .

  In this example, the support member 70 having the same specification is used for both the upper side corner and the lower side corner of the glass plate 12. However, for example, the support member that supports the upper side corner has a degree of freedom. It is possible to use a partly restricted one so that the glass plate 12 can be easily positioned.

  On the other hand, as shown in FIG. 1, the ring-shaped scissors members 16, 16... Are connecting members having rods (wires) 110, 110. Are connected to each other through auxiliary support to prevent deformation and stabilize the posture.

The connecting member according to the embodiment of the present invention includes a rod 110 and a joint 112 that connects the two upper and lower rods 110 and 110 in the hole 17 opened in the ring-shaped flange member 16. The rod 110 is given a predetermined tension by the joint 112, and the structure 10 is given rigidity by this tension.

  As shown in FIGS. 13 and 14, the joint 112 includes a spherical bearing 114, a rod lower support 118, a rod upper support 124, and the like. The spherical bearing 114 is attached to the hole 17 of the ring-shaped flange member 16. The rod lower support 118 is formed with a sphere 116 supported by the spherical bearing 114 and a spherical hole 117 for supporting the lower sphere 110A of the rod 110. As a result, the hole 17 of the ring-shaped saddle member 16 is provided with a double spherical rotating body having a rotational center substantially coincided with the spherical bearing 114 and the spherical body 116, the lower spherical body portion 110 </ b> A and the spherical hole 117.

  Furthermore, the rod upper support 124 is formed with a male screw portion 122 that is screwed into the female screw portion 120 of the rod lower support 118 and a through hole 123 that is engaged with the upper engagement portion 110B of the rod 110. With this configuration, the upper part of the rod 110 is supported by one spherical rotating body composed of the spherical bearing 114 and the spherical body 116, and the lower part of the rod 110 is composed of the spherical hole 117 and the lower spherical body part 110A. Supported by

  The spherical bearing 114 includes an upper bearing 126 and a lower bearing 128 in consideration of ease of attachment to the hole 17. Further, the upper bearing 126 and the lower bearing 128 are formed by pressing the spherical body 116 of the rod lower support 118 against the upper bearing 126 mounted in the hole 17, and then lowering the lower bearing 128 against the female thread portion 127 formed on the upper bearing 126. The male threaded portion 129 formed in is attached to the hole 17 by screwing. At this time, since the spherical body 116 is sandwiched between the upper bearing 126 and the lower bearing 128, the rod lower support 118 is swingably supported by the spherical bearing 114, and the spherical hole 117 of the rod lower support 118 is provided. On the other hand, the lower sphere portion 110A of the rod 110 is supported so as to freely swing (the action of a double spherical rotating body). Therefore, the rod lower support body 118 and the lower sphere part 110A are rotatable independently of each other.

  Further, the male threaded portion 122 of the rod upper support 124 is screwed into the female threaded portion 120 of the rod lower support 118 as shown in FIG. Thereby, the rods 110 and 110 are connected via the joint 112 attached to the ring-shaped flange member 16, and the tension applied to the rods 110 and 110 is adjusted by adjusting the screwing amount of the male screw 122 into the female screw part 120. Can be adjusted. The rod 110 is attached to the rod lower support 118 by, for example, inserting the rod 110 in which the upper engagement portion 110B is not formed from below the rod lower support 118 into the spherical hole 117, and then the rod upper support. What is necessary is just to insert in the through-hole 123 of 124, and to form the upper engaging part 110B after that. Further, instead of forming the upper engaging portion 110B, the rod 110 upper portion and the rod upper support 124 may be fixed by bolts after the rod 110 is inserted into the through hole 123. Similarly, the lower sphere portion 110A may be provided after the rod 110 is inserted into the rod lower support 118.

  According to the connecting member of the ring-shaped scissors member 16 configured as described above, the rods 110, 110 disposed on the top and bottom cannot be disposed in a straight line, or due to an attachment error of the ring-shaped scissors member 16 or the like. Even when the positions of the holes 17 and 17 of the ring-shaped scissors members 16 and 16 positioned above and below are displaced, the displacement is absorbed by the follow-up action of the double spherical rotating body. The ridge members 16, 16 can be connected without any problem.

  Further, the rod 110 can be easily inclined at an inclination angle along the dome shape by the follow-up operation of the double spherical rotating body. Moreover, since the ring-shaped flange member 16 is not restrained in the rotational direction at the connecting position by the double spherical rotating body, the generation of local stress is prevented, and the strength performance of the ring-shaped flange member 16 is improved. Similarly, since bending does not occur in the rod 110, the rod 110 can be formed in a relatively thin shape. Furthermore, even if the displacement occurs in the ring-shaped saddle member 16 later, the displacement can be absorbed by the following operation of the double spherical rotating body.

  In the embodiment, the ring-shaped eaves member 16 is exemplified as the structural member. However, the present invention is not limited to this, and the connection member of the embodiment is also used in the connection of the beam members constituting the structure. Can do.
