Description

The present invention relates to a method of attaching a plurality of plate-shaped members to another one or two plate-shaped members at predetermined intervals.

Conventionally, a resistance plate (internal steel plate) fixed to the upper beam and a viscous body fixed to the lower beam fill the interlayer deformation caused by the shaking of buildings such as office buildings, apartment houses, and detached houses during earthquakes and strong winds. A vibration control wall is used that replaces the relative motion with the viscous container (external steel plate) and absorbs the vibration energy by the resistance force generated at that time.

In the seismic control wall, for example, as shown in FIG. 7, the resistance plates 119 (119A and 119B) constituting the seismic control wall are welded and fixed to the ceiling plate 118 at a predetermined interval, and the ceiling plate 118 is a lower gusset. The lower gusset plate 112, which is welded and fixed to the plate 112, and the upper gusset plate 111, which is fixed to the upper beam (not shown), are fastened by a pair of splice plates 113, 114, high-strength bolts 115, and nuts 116.

Further, inside the viscous container (not shown), the gap between the outer steel plate (not shown) fixed to the bottom surface of the viscous container at the bottom and the resistance plate 119, and the inner surface of the resistance plate 119 and the viscous container. The gap between the two is filled with a viscous body, and when the resistance plate 119 and the inner surface and the outer steel plate of the viscous material container are relatively horizontally displaced due to vibration during an earthquake or strong wind, the viscous body is subjected to viscous shearing. It is generated, and the damping force due to this viscous shearing damps vibrations such as earthquakes.

When the number of the resistance plates 119 is increased to, for example, four, the resistance plates 119 (119A to 119D) are welded and fixed to the ceiling plate 118 at predetermined intervals as shown in FIG. (Upper gusset plate 111 to nut 116) may be the same as the mounting method shown in FIG. 7.

However, in the method of attaching the plate-shaped member shown in FIGS. 7 and 8, since the resistance plate 119 is welded and fixed to the ceiling plate 118, tension is generated at the joint, and UT inspection (Ultrasonic Testing) is performed. ) Is required, and there is a problem that the manufacturing cost and the installation cost are high. Further, when the number of resistance plates 119 is increased to four as shown in FIG. 8, it is not easy to weld and fix the resistance plates 119 (119A to 119D) to the ceiling plate 118.

Therefore, as shown in FIG. 9, in constructing the vibration control wall including the four resistance plates 129 (129A to 129D), the spacer plates 122 on both sides of the upper gusset plate 121 fixed to the upper beam (not shown). 123 is interposed, and these are fastened by a pair of splice plates 124, 125, high-strength bolts 126 and nut 127, and spacer plates 128 (128A to 128C) are interposed between adjacent resistance plates 129 (129A to 129D). It is conceivable that these are bound by the splice plates 124 and 125, the high-strength bolts 126 and the nut 127. According to this method, since the resistance plate 129 is not welded and fixed, UT inspection becomes unnecessary, and the manufacturing cost and the installation cost can be reduced.

However, in the method shown in FIG. 9, the four resistance plates 129 with the spacer plate 128 interposed therebetween are further sandwiched between the splice plates 124 and 125, so that the overall thickness is increased. Therefore, the high-strength bolt 126 needs to be longer than the standard product, and there is a problem that the manufacturing cost increases accordingly.

Further, not limited to the resistance plates 119 and 129 of the vibration control wall, there are various structures such as a viscous damper using a multi-layer plate in which a plurality of plate-shaped members are attached to other members at predetermined intervals. In the case of, the same problem as described above occurs.

Therefore, the present invention has been made in view of the problems in the conventional method for attaching plate-shaped members, and when attaching a plurality of plate-shaped members to other members at predetermined intervals, the manufacturing cost and The purpose is to keep the installation cost low.

In order to achieve the above object, the present invention is a method for attaching a plate-shaped member, in which a plurality of first plate-shaped members are attached to one second plate-shaped member at predetermined intervals. Splice plates are tightly connected to both sides of the plate-shaped member, a spacer plate is interposed between each of the adjacent first plate-shaped members, and at least one of the first plate-shaped member and the spacer plate (provided that the first plate-shaped member is provided). 1 except in the case of all of the plate-like member and said spacer plate) sandwiched by the two splicing plates, the the two splicing plates, and a first plate member及bis Pesapure bets that the clamping Tightened However, it is characterized in that all of the first plate-shaped members and all of the spacer plates are fastened at a position other than between the two splice plates .

According to the above invention, since the first plate-shaped member is not welded and fixed, UT inspection becomes unnecessary, and manufacturing cost and installation cost can be reduced. Further, since all of the first plate-shaped member and the spacer plate are not sandwiched between the two splice plates, the overall thickness can be reduced. For example, when a high-strength bolt is used for binding, the bolt is a standard product. It is also possible to do so without increasing the manufacturing cost.

In the above method for attaching plate-shaped members, when attaching three or more first plate-shaped members to one second plate-shaped member at predetermined intervals, at least one set (excluding all sets). ) Adjacent to the first plate-shaped member and the spacer plate located between the adjacent first plate-shaped members are sandwiched between the two splice plates, and the two splice plates and the sandwiched. a first plate member及bis Pesapureto can be Tightened.

In the method of attaching the plate-shaped member, in connecting all of the first plate-shaped member and all of the spacer plate, the second plate is formed in the length direction of the first plate-shaped member and the spacer plate. and the first plate member to be Tightened with distance from Jo members the number of the spacer plates is increased stepwise, eventually all of the first plate member and the spacer plate can be frettage binding .. Thereby, even when the number of the first plate-shaped members is large, the first plate-shaped members and the spacer plate can be maintained in a stable state.

As described above, according to the present invention, when a plurality of plate-shaped members are attached to other members at predetermined intervals, it is possible to keep the manufacturing cost and the installation cost low.

Next, a mode for carrying out the present invention will be described in detail with reference to the drawings.

A first embodiment of the method for attaching a plate-shaped member according to the present invention will be described with reference to FIG. This mounting method is used when constructing a vibration control wall including four resistance plates 9 (9A to 9D). Splice plates 2 and 3 are interposed on both sides of the gusset plate 1 fixed to the upper beam (not shown), and these are fastened by high-strength bolts 4 and nuts 5. Spacer plates 8 (8A to 8C) are interposed between the resistance plates 9A to 9D, the resistance plates 9B and 9C are extended toward the gusset plate 1, and the outer surfaces of these are brought into contact with the inner surfaces of the splice plates 2 and 3. The resistance plates 9B and 9C, the spacer plate 8B extended to the gusset plate 1 side, and the splice plates 2 and 3 are fastened by the high-strength bolts 6 and nuts 7. Further, all of the resistance plate 9 and the spacer plate 8 are fastened by the high-strength bolt 10 and the nut 11.

According to this method, since the resistance plate 9 is not welded and fixed, UT inspection becomes unnecessary, and the manufacturing cost and the installation cost can be reduced. Further, since not all of the resistance plate 9 and the spacer plate 8 are sandwiched between the splice plates 2 and 3, but a part thereof (resistance plates 9B, 9C and the spacer plate 8B) is sandwiched, the overall structure can be made thin. Since standard products can be used as high-strength bolts 4, 6 and 10, the manufacturing cost does not increase.

Next, a second embodiment of the method for attaching a plate-shaped member according to the present invention will be described with reference to FIG. This mounting method is used when constructing a vibration control wall including six resistance plates 29 (29A to 29F).

In addition, all of the resistance plates 69 (69A to 69G) and the spacer plates 68 (68A to 68F) are fastened by the high-strength bolts 72 and nuts 73.

According to this method, in addition to the effect in the second embodiment, the number of resistance plates 69 sandwiched between the splice plates 62 and 63 is increased, so that more vibration energy can be absorbed as a damping wall. It will be possible. Further, the resistance plate 69 and the spacer plate 68 are gradually increased in the length direction thereof, and finally all the resistance plates 69 and the spacer plate 68 are tightly connected, so that the resistance plate 69 and the spacer plate 68 are in a stable state. Can be maintained at.

Next, a first reference example of the method for attaching the plate-shaped member according to the present invention will be described with reference to FIG.
