Description

  The present invention relates to a structure joining member provided between a building structure such as a pillar member or a beam member and a structure such as a brace (bar brace) provided thereon, and a method for attaching the structure joining member.

  As a conventional structure joining member, there exists a thing as described in patent document 1, for example.

  The conventional structure joining member described in Patent Document 1 includes a female screw formed on the inner surface of both ends of a long pipe material constituting one of the structures, and a cylinder on the opposite side to the U-shaped portion of the clevis member. The gusset plate provided on the other side of the structure is fitted between the U-shaped portion of the clevis member, and the U-shaped portion of the gusset plate and the clevis member By providing a clevis pin that penetrates the structure, one and the other of the structure are joined together.

  The two female screws formed on the inner surfaces of both ends of the pipe member have opposite spiral directions, and correspondingly, two clevis members that are screw-coupled to the two female screws. The male screws also have opposite spiral directions.

For this reason, since one pipe material and the two clevis members at both ends thereof have the same function as the turnbuckle, the clevis eye of one clevis member is connected to one gusset plate via a fitting pin. After that, when the clevis eye of the other clevis member is displaced from the hole of the other gusset plate and the clevis pin cannot be provided, the two clevis members are prevented from rotating and only the pipe material is rotated to Since the two clevis members can approach or separate from each other, the clevis eye of the other clevis member and the hole of the other gusset plate can be easily aligned.
JP-A-8-128108

  However, in the above-described conventional structure joining member, since it is necessary to screw-connect to the clevis member at both ends of the pipe material, a female screw and a male screw must be attached to both ends of the pipe material and the two clevis members, respectively. Since it must be formed, there is a problem that the number of processing steps increases and the cost of the structure joint member increases.

  In the conventional structure joint member, the two clevis members at both ends of the pipe material approach or separate from each other so that the other clevis member is aligned with the other structure to be joined thereto. In order to do this, since the entire pipe material has to be rotated, there is a problem that a large amount of labor is required when the diameter, length, weight, etc. of the pipe material are large.

  Furthermore, in the conventional structure joint member, since both ends of the pipe material are joined to the structure via the clevis member, the cost increases as the number of parts increases, The gaps in the fitting portion accumulate and cause large backlash, reducing the vibration control function and the earthquake resistance function against the external force in the axial direction of the pipe material. In addition, if the mounting surface of the clevis member and the corresponding surface of the structure to which it is attached are inclined with respect to each other, forcibly mounting will cause stress that bends the pipe material. There was a problem that the seismic function and the like were reduced.

  Therefore, in view of the above problems, the present invention prevents an increase in cost, does not require a large amount of labor for alignment with a structure, and further accumulates gaps between the fitting portions to cause a large backlash. It is an object of the present invention to provide a structure bonding member and a method for attaching the structure bonding member that can prevent the occurrence of stress or the occurrence of stress that bends one of the structures.

In order to solve the above problems, the present invention

A support member rotatably supported so as to wrap around the spherical portion of the ball joint member,
In a structure joint member provided between a pair of structures to be joined together, the ball joint member is connected to one of these structures, and the support member is connected to the other of the structures,
A screw portion that is screw-coupled to one of the structures is formed on the rod-shaped portion of the ball joint member, and
An engaging portion for engaging with a tool for rotating the ball joint member around the axis is formed in the vicinity of the spherical portion of the rod-shaped portion of the ball joint member.

  According to the present invention, it is possible to prevent an increase in cost, do not require a large amount of labor to align with the structure, and further, the gaps between the fitting portions are accumulated, resulting in a large backlash. It is possible to prevent the occurrence of stress that bends one of the structures.

Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings.
FIGS. 1-7 is a figure referred in order to demonstrate the structure joining member 20 which concerns on one embodiment of this invention, and its attachment method.

  As shown in FIG. 1, the structure joining member 20 according to this embodiment includes a lower left end portion of the vibration control member 25 (structure) used also as a brace (a brace) and a building structure 23. It is provided to join the mounting plate 30a of the structure 30 provided at the corner where the column member 26 and the beam member 28 intersect. And the structure joining member 20A is provided also between the upper right end part in the figure of the damping member 25 and the mounting plate 30a of the structure 30 in the vicinity thereof.

The vibration control member 25 is composed of a pipe member 25a (see FIG. 2) and an end plate member 25b (see FIG. 2) welded to both ends thereof.
As shown in FIG. 2, the structure bonding member 20 includes a ball joint member 32 and a support member 34.

  As shown in FIG. 3, the ball joint member 32 of the structure joining member 20 has a spherical portion 32a and a rod-like portion 32b formed integrally with the spherical portion 32a. The rod-shaped portion 32b is formed with a male screw 32c that is screw-coupled to a female screw 25c (see FIG. 2) at the center of the end plate member 25b of the vibration control member 25. Two engaging holes 32d for engaging a tool (not shown) for rotating the ball joint member 32 are formed in the vicinity of the spherical portion 32a of the rod-like portion 32b.

  The support member 34 is configured to wrap around the spherical portion 32a of the ball joint member 32 and rotatably support it. The support member 34 has a first support member 36 having a concave spherical surface portion 36a that contacts the left half portion of the spherical portion 32a in the drawing, and a concave spherical portion 38a that contacts the right half portion of the spherical portion 32a in the drawing. The second support member 38 is divided into two parts.

  The first support member 36 and the second support member 38 of the support member 34 are integrally connected by screwing the female screw 36b and the male screw 38b, so that the spherical portions 32a of the ball joint member 32 are mutually connected. Support to wrap. Two engagement holes 38c are formed on the surface of the second support member 38 on the side of the rod-shaped portion 32b of the ball joint member 32, and a tool (not shown) for rotating the second support member 38 is engaged therewith. ing.

2, the support member 34 of the structure joining member 20 is fixed to a mounting plate 30a of the structure 30 shown in FIG. 1 by fixing means such as welding or screwing.
The above is a description of the structure bonding member 20 that has already been mounted, but a mounting method for mounting the structure bonding member 20 will be described below.

  First, as shown in FIG. 4, at one end of the vibration control member 25, the second support member 38 of the support member 34 of the structure joint member 20 is rotated, and the second support member 38 projects outward from the first support member 36. As a result, a gap is left between the spherical portion 32a of the ball joint member 32 and the concave spherical portion 38a of the second support member 38, and the relative rotation between the support member 34 and the spherical portion 32a is made smooth. be able to.

  And the surface 36c on the opposite side to the 2nd support member 38 of the 1st support member 36 of the support member 34 is made to oppose the attachment plate 30a of the structure 30 shown in FIG. 1, and between the attachment plates 30a. Place with a gap. The reason why the gaps are arranged in this way is that if there is no such gap, the surface 36c cannot be opposed to the mounting plate 30a.

  By the way, before making such a state, another structure joint member 20A provided at the other end portion of the vibration control member 25 has a support member 34 that is different from the other end portion side of the vibration control member 25. It is assumed that the structure 30 is already connected to the mounting plate 30a.

  The structure joining member 20 in the state of FIG. 4 engages a tool in the engagement hole 32d of the ball joint member 32 and rotates the ball joint member 32 using the tool, thereby controlling the male screw 32c. The screw is moved outward from the female screw 25c of the seismic member 25 in the axial direction.

  Thus, when the ball joint member 32 is rotated so as to move outward in the axial direction, the surface 36c opposite to the second support member 38 of the first support member 36 is finally formed as shown in FIG. , The mounting plate 30a of the structure 30 is contacted. At this time, the first support member 36 of the support member 34 is fixed to the mounting plate 30a of the structure 30 by fixing means such as welding or screwing.

  Then, a tool for rotating the second support member 38 is engaged with the engagement hole 38c of the second support member 38 of the support member 34, and the second support member 38 is rotated using the tool. The second support member 38 moves so as to approach the first support member 36.

  Finally, as shown in FIG. 2, there is no gap between the peripheral surface of the spherical portion 32a of the ball joint member 32 and the concave spherical portion 38a of the second support member 38, and the play can be removed. This completes the attachment of the structure joining member 20.

  In addition, since the structure joint member 20 according to the present embodiment uses the ball joint member 32, the support member 34 can rotate in any direction along the circumferential surface of the spherical portion 32a. It can also be rotated around a horizontal line orthogonal to the axis of the member 32 and passing through the center of the spherical portion 32a.

  Therefore, as shown in FIG. 6, there is a slight inclination between the surface 36 c of the first support member 36 of the support member 34 opposite to the second support member 38 and the mounting plate 30 a of the structure 30. However, when the ball joint member 32 is screw-rotated with respect to the vibration control member 25 and the surface 36c is brought closer to the mounting plate 30a, the surface 36c and the mounting plate 30a are finally connected as shown in FIG. The support member 34 is inclined so as to be in uniform contact with the entire surface, and the gap between the surface 36c and the mounting plate 30a can be removed. For this reason, it can prevent that the stress which bends the damping member 25 conventionally is generated.

  According to the structure joint member 20 according to the embodiment of the present invention, the ball joint member 32 and the vibration control member 25 of the structure joint member 20 at both ends of the vibration control member 25 are not necessarily provided as in the related art. Since it is not necessary to cut the screw on the end plate member 25b and clevis is not used, it is possible to prevent an increase in the number of processing steps and the number of parts and an increase in cost.

  In addition, according to the structure joining member 20 according to the embodiment of the present invention, it is not necessary to rotate the entire pipe member 25a of the vibration control member 25 as in the prior art, and a structure at one end of the vibration control member 25 is provided. Since only the ball joint member 32 of the joining member 20 needs to be rotated, in order to align the one structure joining member 20 at both ends of the vibration control member 25 and the mounting plate 30a of the structure 30 joined thereto. It doesn't require much effort.

  Moreover, according to the structure joining member 20 according to the embodiment of the present invention, the support member 34 is divided, and the divided first and second support members 36 and 38 are moved relative to each other. Since the gap between the support member 34 and the spherical portion 32a can be easily removed, it is possible to prevent the gap between the fitting portions from accumulating and generating large play as in the conventional case, and to control the vibration control member 25. It can prevent that a function, an earthquake-proof function, etc. reduce.

  Further, according to the structure joining member 20 according to the embodiment of the present invention, the support member 34 is divided into the first support member 36 and the second support member 38, and the bar-shaped portion 32 b side of the ball joint member 32. The second support member 38 has an engagement hole 38c so that the second support member 38 can be operated from the same bar-shaped portion 32b side.

  For this reason, as shown in FIG. 5, even after the surface 36c of the first support member 36 of the support member 34 is fixed to the mounting plate 30a of the structure 30, the engagement hole 38c of the second support member 38 is inserted into the ball joint. It is possible to adjust the size of the clearance between the support member 34 and the spherical portion 32a of the ball joint member 32 by operating from the rod-like portion 32b side of the member 32.

  In the above embodiment, the two engaging holes 32d are formed at intervals of 180 ° in the rod-shaped portion 32b of the ball joint member 32. However, as shown in FIG. 8, the rod-shaped portion 32b has an interval of 90 °. The four engagement holes 32d may be formed in this manner. By doing so, it is possible to prevent the tool from becoming difficult to engage depending on the rotational position of the ball joint member 32.

  In the above embodiment, the engagement hole 32d is formed in the rod-shaped portion 32b of the ball joint member 32. However, as shown in FIG. 9, the rod-shaped portion 32b is cut instead of the engagement hole 32d. The notch surface 32e may be formed, and in this way, a tool of a different type from the tool used in the above embodiment can be used.

  In the above embodiment, the first support member 36 and the second support member 38 of the support member 34 are connected to each other by screwing the female screw 36b and the male screw 38b. However, as shown in FIG. In addition, the first support member 42 and the second support member 44 of the support member 34 may be coupled by the bolt 40.

  In the above embodiment, the case where the rod-like portion 32b of the ball joint member 32 is screw-coupled to the vibration control member 25 and the support member 34 is fixed to the mounting plate 30a of the structure 30 is described. The rod-like portion 32 b of the ball joint member 32 may be screwed to the mounting plate 30 a of the structure 30 and the support member 34 may be fixed to the vibration control member 25.

  Moreover, in the said embodiment, although what used the pipe material for the damping member 25 was demonstrated, it is not necessary to limit to it, What kind of structures, such as H-shaped steel, I-shaped steel, L-shaped steel other than a pipe material? You may use thing.

  Moreover, in the said embodiment, although the structure joining member 20 was used in order to join between the structure 30 of the building structure 23, and the damping member 25 which served as the brace, the effect of this invention is used. As long as it can be obtained, the structure bonding member according to the present invention can be used for bonding between any other structures.
