[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2015-113955 Summary of the Invention [Problem to be solved by the invention]

[0004] When a brace-type structure is installed at a construction site, the brace-type member may be manufactured in advance at a production facility. In this case, in order to place the brace-type member manufactured at the production facility between a pair of brace members at the construction site, it is necessary to accurately manufacture the length of the brace-type member in the installation direction during production. Here, if it is discovered at the construction site that the length of the brace-type member in the installation direction at the time of production is longer or shorter than expected, it is necessary to adjust the length of the brace-type member in the installation direction to fit the installation location. However, the adjustment work of the length of the brace-type member in the installation direction is complicated, and there have been cases where the length of the brace-type member in the installation direction cannot be adjusted in the first place, making construction impossible.

[0007] The main invention for achieving the above-mentioned object is a method for installing a brace-type structure having a brace-type member (excluding buckling restraint braces) manufactured in a production facility and a frame on which the brace-type member is installed, the method having a pair of frame-side joints where the frame and the brace-type member are joined, the brace-type member having a first member and a second member separated between the pair of frame-side joints, and an attachment member that connects the first member and the second member and is bolted together, one of the bolt holes on the attachment member side of the attachment member, which is the first member and the second member, and the bolt holes on the attachment member side of the attachment member is an elongated hole, and a bolt is inserted into the bolt hole on the attachment member side and the bolt hole on the attachment member side to join the attachment member and the attachment member.

[0020] Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings. The same or equivalent components, members, etc. shown in the drawings will be designated by the same reference numerals, and redundant descriptions will be omitted where appropriate.

[0021] ===This embodiment=== <<About brace-type components>> The brace-type member of this embodiment is a member incorporated into a brace that connects both ends of a diagonal line (column-beam joint) in a column-beam frame (building frame) surrounded by columns and beams. The brace-type member of this embodiment is, for example, a brace-type friction damper. Note that the brace-type member is not limited to a friction damper as long as it is a member that can be incorporated into a brace. However, the brace-type member of this embodiment does not include a buckling-restrained brace. Hereinafter, a column-beam frame may be simply referred to as a "frame." Furthermore, a structure in which a brace-type member is installed in a column-beam frame may be referred to as a "brace-type structure."

[0022] In the following, we will use a friction damper as an example of a brace-type component installed on a column-beam frame, but the explanation of the installation structure and installation method for the brace-type structure will also be the same when a brace-type component other than a friction damper is installed on a column-beam frame.

[0023] As described above, the brace-type member of this embodiment is a brace-type friction damper, and suppresses vibrations by using the friction force between pressure-welded plates (not shown) that occurs with relative movement in the brace span direction (in this embodiment, the relative movement of a pair of brace segments 5, 6, which will be described later).

[0024] When a brace-type structure is to be installed at a construction site, the brace-type members may be manufactured in advance at a production facility. In this case, in order to place the brace-type members manufactured at the production facility between a pair of brace members at the construction site, it is necessary to precisely manufacture the length of the brace-type members in the spanning direction during production.

[0025] In this embodiment, even if it is discovered at the construction site that the length of the brace-type component in the span direction during production is longer or shorter than expected, the length of the brace-type component can be easily adjusted to suit the installation location.

[0026] <<Brace structure configuration>> Hereinafter, the brace-type member 10 of this embodiment that is installed on a beam-column frame 1 will be described with reference to the drawings.

[0027] Fig. 1 is a schematic explanatory diagram of a brace-type member 10 of this embodiment installed on a column-beam frame 1. Fig. 2A is a plan view of a splice member 8 of this embodiment, and Fig. 2B is a plan view of a first member 11 and a second member 12 of a brace piece 5 of this embodiment. As shown in Fig. 1, the brace-type member 10 of this embodiment is a brace-type friction damper incorporated into a brace of a column-beam frame 1 (building frame) surrounded by a column 1a erected in the vertical direction and a beam 1b extending in the horizontal direction.

[0028] Hereinafter, the brace spanning direction in Fig. 1 is referred to as the X direction, and the direction perpendicular (intersecting) to the X direction in the structural plane of the beam-column frame 1 is referred to as the Y direction. The direction perpendicular to the X and Y directions (the direction perpendicular to the paper surface in Fig. 1) is referred to as the Z direction. The X direction corresponds to the "predetermined direction."

[0029] As shown in Fig. 1, a pair of gusset plates 2 are provided at both diagonal ends (column-beam joints) of the column-beam frame 1. The gusset plates 2 are fixed (joined) to the column 1a and the beam 1b by, for example, welding. A pin joint structure 3 (corresponding to a "frame-side joint") is rotatably joined (pin-jointed) to each of the pair of gusset plates 2. A brace 4 is provided between the pair of pin joint structures 3 at the diagonal positions of this column-beam frame 1.

[0030] The brace 4 is mainly made up of H-shaped steel, which is divided at an appropriate position at a predetermined distance from each other to form a pair of brace segments 5, 6. The pair of brace segments 5, 6 corresponds to a "pair of members." The brace segments 5, 6 are each fixed (joined) to the pin joint structure 3, which allows them to move relative to each other in the X direction (predetermined direction). The brace segments 5, 6 are connected by a connecting member 7. The connecting member 7 in this embodiment is made of a C-shaped steel.

[0031] In this embodiment, the brace fragment 5 is further divided at appropriate positions at a predetermined distance S from each other, as shown in FIG. 2B, to form first members 11 and second members 12. The first members 11 and second members 12 are then connected by splice members 8, as shown in FIG. 1. By dividing the brace fragment 5 further into the first members 11 and the second members 12 in this way, the first members 11 and the second members 12 alone are lighter than the entire brace fragment 5, making it easier to transport to a construction site. In addition, the first members 11 and the second members 12 alone are shorter in the laying direction (X direction) than the entire brace fragment 5, making construction easier.

[0032] In the above, an example has been described in which the brace fragment 5 is separated into the first member 11 and the second member 12. However, it is also possible for the brace fragment 6, instead of the brace fragment 5, to be separated into the first member 11 and the second member 12 and connected by the splice member 8. However, as will be described later, the brace fragment 6 has a shorter length in the X direction than the brace fragment 5 (conversely, the brace fragment 5 has a longer length in the X direction than the brace fragment 6), and therefore separating the brace fragment 5, which is longer in the X direction, has great advantages in terms of ease of transport to the construction site and ease of construction, as described above.

[0033] The brace-type member 10 of this embodiment is incorporated into the brace 4, and includes brace pieces 5 and 6, a connecting member 7, a splice member 8, and a fastening member 20. A plurality of fastening members 20 (eight in this example) are arranged side by side in the X direction.

[0034] The configuration of each component of the brace-type component 10 will be described below.

[0035] As shown in Fig. 1, the brace fragment 5 is a steel material (H-beam) having an H-shaped cross section, in which a pair of flanges 5f are connected at approximately the center by a web 5w. In this embodiment, the brace fragment 5 is arranged so that the web 5w of the brace fragment 5 is along the structural surface of the beam-column frame 1. Also, as shown in Fig. 1, one end of the brace fragment 5 (the end on the beam-column joint side) is fixed (joined) to the pin joint structure 3.

[0036] As shown in FIG. 1 , the brace segment 6 is also a steel material (H-shaped steel) having the same cross-sectional shape as the brace segment 5, and has a pair of flanges 6f and a web 6w. The brace segment 6 of this embodiment is shorter in length in the X direction than the brace segment 5, and the web 6w of the brace segment 6 has bolt holes (not shown) for joining the connecting member 7, which correspond to bolt holes 7c (described later) in the web 7w of the connecting member 7. Also, as shown in FIG. 1 , one end of the brace segment 6 (the end on the column-beam joint side) is fixed (joined) to the pin joint structure 3, similar to the brace segment 5.

[0037] The connecting member 7 is a steel material (C-beam) with a roughly U-shaped cross section, and has a pair of flanges 7f and a web 7w. The connecting member 7 is bridged between the brace segment 5 and the brace segment 6 that make up the brace 4. The length (width) of the connecting member 7 in the Y direction is shorter than the length (the distance between the pair of flanges 5f) of the web 5w of the brace segment 5 in the Y direction. This allows the web 7w of the connecting member 7 to be arranged so as to overlap the web 5w of the brace segment 5, as shown in FIG. 1. The same applies to the relationship between the brace segment 6 and the connecting member 7. The connecting member 7 is joined to the brace segment 6 by bolts 30 or the like shown in FIG. 1. The connecting member 7 is arranged so as to be displaceable relative to the brace segment 5.

[0038] The splicing members 8 are steel materials (flat steel) having a substantially plate-like cross section, and are bridged and spliced ​​between the first member 11 and the second member 12 (the first member 11 and the second member 12 may be collectively referred to as "spliced ​​members") that make up the brace section 5. In detail, the splicing members 8 are provided (in a pair) on both sides of the web 5w of the first member 11 and the second member 12 so as to sandwich the web 5w therebetween, and further, the splicing members 8 are provided (in a pair) on both sides of the web 5w so as to sandwich each of the pair of flanges 5f of the first member 11 and the second member 12. The splicing members 8 are provided on both sides of the flange 5f so as to fit into the brace fragment 5. Therefore, in this embodiment, a total of ten splicing members 8 are provided on the brace fragment 5. The splicing members 8 also join the web 5w of the first member 11 (brace fragment 5) and the web 5w of the second member 12 (brace fragment 5), and also join the pair of flanges 5f of the first member 11 (brace fragment 5) and the pair of flanges 5f of the second member 12 (brace fragment 5).

[0039] In the following, an example of one adhesive member 8 provided on the web 5w of the first member 11 and the second member 12 will be used for explanation, but the detailed explanation of the adhesive member 8 will also be the same for adhesive members 8 provided on other parts of the first member 11 and the second member 12.

[0040] The length (width) of the splice members 8 provided on the webs 5w of the first member 11 and the second member 12 in the Y direction is shorter than the length (the distance between the pair of flanges 7f) of the webs 5w of the brace segment 5 (the first member 11 and the second member 12) in the Y direction. This allows the splice members 8 to be arranged so as to overlap the webs 5w of the brace segment 5 (the first member 11 and the second member 12), as shown in FIG.

[0041] The splice member 8 is joined to the brace segment 5 by bolts 40 or the like shown in Fig. 1 (the first member 11 and the second member 12 are connected and bolted together). In more detail, the splice member 8 is joined to the first member 11 at the portion where the splice member 8 overlaps with the web 5w of the first member 11 of the brace segment 5, and the splice member 8 is joined to the second member 12 at the portion where the splice member 8 overlaps with the web 5w of the second member 12 of the brace segment 5.

[0042] The fastening member 20 has a bolt, such as a high-strength bolt, which is inserted through a through-hole (not shown) in the web 7w of the connecting member 7 and a through-hole (not shown) in the web 5w of the brace segment 5. A nut is threaded onto the tip of the bolt. The web 5w of the brace segment 5 is fastened while sandwiched between the webs 7w of the pair of connecting members 7 by a pressure force applying unit, which is formed by adding a disc spring, guide bush, etc. (not shown) to the bolt and nut, and thereby a pressure force (equivalent to a predetermined pressure force) for sandwiching is applied in the plate thickness direction (Z direction).

[0043] This pressing force causes the web 5w of the brace segment 5 to come into contact with the web 7w of the connecting member 7 via a friction plate and a sliding plate (not shown). Therefore, when the connecting member 7 slides against the brace segment 5, a friction force corresponding to the pressing force is generated. This friction force then acts as a damping force for the vibration of the beam-column frame 1.

[0044] <<Bolt holes of the splice member and the member to be spliced>> Next, the bolt holes of the pressing member and the pressed member of this embodiment will be described. Hereinafter, the bolt hole on the pressing member side will be referred to as the "pressing member-side bolt hole," and the bolt hole on the pressed member side will be referred to as the "pressed member-side bolt hole."

[0045] 2A, the splicing member 8 of this embodiment is provided with a plurality of (four in this embodiment) bolt holes 8a penetrating in the Z direction and spaced apart in the X direction. Specifically, the four bolt holes 8a include two bolt holes 8a on one side in the X direction (the side where the splicing member 8 overlaps with the first member 11) and two bolt holes 8a on the other side in the X direction (the side where the splicing member 8 overlaps with the second member 12). The bolt holes 8a are provided to correspond to the bolts 40 shown in FIG. 1 described above, and the diameter of the bolt holes 8a is slightly larger than the diameter of the bolts 40.

[0046] As shown in FIG. 2B, the member to be joined (first member 11) of this embodiment has a plurality of (two in this embodiment) elongated holes 11a that penetrate in the Z direction and are long in the X direction. Also, as shown in FIG. 2B, the member to be joined (second member 12) of this embodiment has a plurality of (two in this embodiment) elongated holes 12a that penetrate in the Z direction and are long in the X direction. The length of each of the elongated holes 11a, 12a in the major axis direction (X direction) is greater than the diameter of the bolt hole 8a described above. Each of the elongated holes 11a, 12a is provided to correspond to the bolt 40 shown in FIG. 1 described above.

[0047] When connecting and bolting the members to be joined (first member 11 and second member 12) using the splicing member 8, the bolt 40 is inserted through the bolt hole 8a of the splicing member 8 and the elongated hole 11a of the first member 11 (or the elongated hole 12a of the second member 12) and fastened. Here, as described above, because the bolt hole on the member to be joined is formed as an elongated hole (elongated holes 11a, 12a) that is long in the X direction (the brace placement direction), the position of the elongated hole (elongated holes 11a, 12a) of the fastening bolt 40 in the X direction (the brace placement direction) can be flexibly determined. Therefore, even if the length of the brace-shaped member 5 or the brace-shaped member 6 in the X direction (the brace placement direction) is longer or shorter than expected, this can be easily adjusted when connecting and bolting the members to be joined (first member 11 and second member 12) using the splicing member 8. In other words, when the brace-type member 10 manufactured at the production facility is installed on the brace 4 of the column-beam structure 1 at the construction site, the length of the brace-type member 10 can be easily adjusted to fit the installation location.

[0048] In the above-described embodiment, the bolt holes on the member to be pressed are elongated holes, but the bolt holes on the pressing member may also be elongated holes.

[0049] FIG. 3A is a plan view of a splice member 9 of a modified example, and FIG. 3B is a plan view of a first member 13 and a second member 14 of a brace piece 5 of a modified example.

[0050] As shown in Fig. 3A, the splicing member 9 of the modified example has a plurality of (four in this embodiment) elongated holes 9a formed therein, which penetrate in the Z direction and are long in the X direction. The length of the elongated holes 9a in the major axis direction (X direction) is greater than the diameters of bolt holes 13a and 14a, which will be described later. The elongated holes 9a are provided to correspond to the bolts 40 shown in Fig. 1 described above.

[0051] As shown in Fig. 3B, the member to be joined (first member 13) of the modified example has a plurality of (two in this embodiment) bolt holes 13a penetrating in the Z direction and spaced apart in the X direction. Also, as shown in Fig. 3B, the member to be joined (second member 14) of the modified example has a plurality of (two in this embodiment) bolt holes 14a penetrating in the Z direction and spaced apart in the X direction. Each of bolt holes 13a, 14a is provided corresponding to bolt 40, and the diameter of each of bolt holes 13a, 14a is slightly larger than the diameter of bolt 40 shown in Fig. 1 described above.

[0052] Even in the case of the modified example, if the length of the brace fragments 5 and brace fragments 6 of the brace-type member 10 in the X direction (the direction in which the brace is laid) is longer or shorter than expected, it can be easily adjusted when connecting the spliced ​​members (first member 13 and second member 14) with the splicing members 9 and fastening them with bolts. In other words, when the brace-type member 10 manufactured in the production facility is installed on the braces 4 of the beam-column frame 1 at the construction site, the length of the brace-type member 10 can be easily adjusted to fit the installation location.

[0053] From the above, when installing the brace-type member 10 manufactured at a production facility on the brace 4 of the column-beam structure 1 at a construction site, in order to easily adjust the length of the brace-type member 10 to fit the installation location, it is sufficient if one of the bolt holes on the attached member side and the bolt hole on the attaching member side is an elongated hole.

[0054] <<Brace structure installation procedure>> FIG. 4 is a flow diagram of the installation procedure for the brace-type structure of this embodiment.

[0055] First, the brace-type component 10 is manufactured in a production facility (S001). As described above, in the brace-type component 10 of this embodiment, the brace pieces 5 of the brace-type component 10 are manufactured in a form separated into the first member 11 and the second member 12, and one of the bolt holes on the attached member side (the first member 11 and the second member 12) and the bolt hole on the attaching member side (the attaching member 8) is manufactured to be an elongated hole.

[0056] Next, the brace-type component 10 is transported to the construction site (S002). The first member 11 and the second member 12 are light enough on their own, so they can be easily transported to the construction site. Of the brace-type component 10, the brace-piece fragment 5, which is longer in the X direction than the brace-piece fragment 6, is separated into the first member 11 and the second member 12, and the first member 11 and the second member 12 are light enough on their own compared to the entire brace-piece fragment 5, so they can be easily transported to the construction site.

[0057] Then, at the construction site, the splice members (first member 11 and second member 12) are joined to the splice members 8 (S003). The brace fragment 5, which is longer in the X direction than the brace fragment 6, is divided into the first member 11 and the second member 12. The first member 11 and the second member 12 are individually shorter than the entire brace fragment 5, making construction easier. At this time, even if the length of the brace fragment 5 or the brace fragment 6 of the brace-type member 10 in the X direction (the direction in which the brace is laid) during manufacture (S001) is longer or shorter than expected, this can be easily adjusted when the splice members (first member 11 and second member 12) are connected and bolted together by the splice members 8. In other words, when the brace-type member 10 manufactured at the production facility is installed on the brace 4 of the beam-column frame 1 at the construction site, the length of the brace-type member 10 can be easily adjusted to fit the installation location.

[0058] ===Other embodiments=== The above-described embodiments are intended to facilitate understanding of the present invention and are not intended to limit the present invention. The present invention may be modified or improved without departing from the spirit thereof, and it goes without saying that the present invention includes equivalents thereof. In particular, the embodiments described below are also included in the present invention.

[0059] In the above-described embodiment, the brace pieces 5, 6 and the gusset plates 2 are joined by pin joints using the pin joint structures 3, but this is not limiting and rigid joints may also be used. For example, the brace pieces 5, 6 may be joined to the corresponding gusset plates 2 by welding or bolts without using the pin joint structures 3.

[0060] In addition, in the above-described embodiment, the surfaces of the webs 5w, 6w of the brace fragments 5, 6 were aligned along the structural plane of the column-beam structure 1, but this is not limited to this, and the surfaces of the webs 5w, 6w may be perpendicular to the structural plane of the column-beam structure.
