BACKGROUND OF THE INVENTION
The present invention relates to a method of attaching a vibration control device that damps vibration using viscous shear resistance between upper and lower horizontal members such as between upper and lower beams of a building and between upper and lower floors.
[0002]
[Problems to be solved by the invention]
Recently, in order to prevent damage to buildings due to an earthquake, the whole building is supported by a seismic isolation device so that earthquake vibrations are not transmitted to the building, and a vibration control device is incorporated in the walls of each floor of the building. On the other hand, a method for attenuating the vibration of the building due to the vibration of the earthquake has been proposed.
[0003]
In the latter case, when a damping device that attenuates vibration using viscous shear resistance is used as the damping device, the damping device itself is made of a wide, wide steel resistance plate and a steel that houses this resistance plate. Since the seismic control device is usually assembled in advance at a factory, etc., the pre-assembled seismic control device is brought into the construction site. Once the seismic control device is installed on the upper main beam, etc. at the ground yard, then the upper main beam on which the vibration control device is installed is lifted by a crane or the like and placed between the nodal pillars. Is adopted.
[0004]
By the way, if the occupied area of the building is about the same as the site area of the building site, it is difficult to provide a ground yard in the site. It is not possible to adopt a process that lays the ground on the upper main beam.
[0005]
The present invention has been made in view of the above points, and the object of the present invention is to provide a vibration control device between nodal pillars even if it is difficult to provide a ground yard in the site of a construction site. And providing a simple method that can be mounted between the upper and lower horizontal members.
[0006]
[Means for Solving the Problems]
A vibration control device comprising a container for containing a viscous body and a resistance plate arranged with a gap between the container and a part of the viscous body in the container is disposed above the lower horizontal member of the building. The method of attaching the vibration control device to the building of the present invention that is mounted between the horizontal member and the vibration control device, in which the resistance plate is temporarily fixed to the container so that the resistance plate is not separated from the container, is disposed in advance. A first step of placing on the lower horizontal member and temporarily fixing the lower horizontal member so that at least in the lateral direction does not move on the container side; A second step of disposing a horizontal member, and temporarily mounting the resistance plate to the disposed upper horizontal member so that the resistance plate is movable in the upward direction but not in the lateral direction; Raise the vibration control device toward the upper horizontal member. A third step of fixing the plate to the upper horizontal member, and then a fourth step of releasing the temporary fixing of the resistance plate to the container and lowering the container, and after lowering, fixing the container to the lower horizontal member.

In a preferred example of the present invention, in the first step, the vibration control device is placed on a previously formed lower horizontal member via a spacer, and in the third step, the lower horizontal member formed by the spacer. The vibration control device is raised using a gap between the upper surface of the container and the lower surface of the container. In this case, it is preferable to raise the vibration control device with a claw jack or the like interposed in the gap, since workability is improved.
[0008]
In another preferable example of the present invention, in the first step, the vibration control device is temporarily fixed to the lower horizontal member so as to be stationary in the upward direction, and in the third step, the vibration control device is moved to the lower horizontal member. The temporary stop which becomes immovable with respect to the upward direction is released, and the vibration control device is raised toward the upper horizontal member. In this way, if the vibration control device is temporarily fixed to the lower horizontal member so that it does not move in the upward direction in the first step, the vibration control device can be firmly fixed to the lower horizontal member, and the vibration control device can be immediately installed. Safety can be ensured, for example, when the upper and lower horizontal members cannot be fixed.

Can be made.
[0010]
In still another preferred embodiment of the present invention, the container is filled with the viscous material before the first step or before or after the fourth step. If the container is filled with a viscous material before the first step, this may be done at the factory, but if there is some space, this may be done at the construction site. If the viscous material is filled in the container before this step, the filling operation can be performed without difficulty, which is preferable from the viewpoint of facilitating the filling operation. When the container is filled with a viscous material before or after the fourth step, the risk of leakage of the viscous material during transportation or rainwater intrusion into the container is reduced. This is preferable from the viewpoint of preventing leakage of the viscous material.

Next, as shown in FIG. 6, a slightly long bolt 45 for temporary fixing is inserted into the through holes 17 and 35, and the bolt 45 is screwed into the nut 46 and temporarily tightened. Using the combination of the bolt 45 and the nut 46, the lower main beam 32 is temporarily fixed on the container 3 side so as not to move in the horizontal direction H and the vertical direction V, and the vibration control device 1 is subjected to the following installation process. Do not tip over. In this case, the vertical direction V may be temporarily fixed so as to be movable.
[0022]
After this temporary fixing, the rope locking device 42 and the rope 43 are removed, and then, as shown in FIG. 7, concrete or the like is placed on both sides of the vibration control device 1, or steel such as H-shaped steel is used. The nodal pillars 51 and 52 are erected using the above members. The node columns 51 and 52 may be erected before temporarily fixing the vibration control device 1 to the lower main beam 32, that is, with the lower main beam 32, or before or after the lower main beam 32 is laid. Good. Further, an upper main beam 54 made of a steel member such as H-shaped steel as an upper horizontal member is disposed so as to bridge the node columns 51 and 52 and away from the upper surface 53 of the flange plate 22.
[0023]
As the upper main beam 54 to be prepared before the above arrangement, as shown in the figure, two long and short steel members such as H-shaped steels are fixed to each other by means of welding or the like, or a single H-shaped steel or the like. It may be a steel member. The both ends of the upper main beam 54 are fixed to the node columns 51 and 52 by using a known means such as welding or anchor bolt driving. As an example of the distance between the upper surface 53 and the lower surface 56 of the flange plate 55 of the upper main beam 54, 4 mm to 6 mm can be given.
