  ADVANTAGE OF THE INVENTION According to this invention, the unit building which can improve seismic performance easily, and the damping member for unit buildings which can be attached easily can be provided.

  A unit building according to an embodiment of the present invention will be described below with reference to the drawings. As shown in FIG. 1, the unit building 1 includes four building configuration units 10 a to 10 d and the like. In addition, about the roof and the foundation, illustration is abbreviate | omitted. The building configuration units 10a to 10d are arranged adjacent to each other on the foundation. A roof is attached on these building construction units 10a to 10d. Each of the building configuration units 10a to 10d includes columns 11a to 11d (FIG. 2), ceiling beams 12a to 12d (FIG. 2), floor beams, ceiling beams, ceiling field edges (not shown), floor beams, studs, floor materials, It consists of ceiling materials, wall panels, etc. Each of the building configuration units 10a to 10d has four columns 11a to 11d and four ceiling beams 12a to 12d, respectively.

  The central part of the unit building 1 is shown in FIGS. In the central part of the unit building 1, the four pillars 11a to 11d, which are the pillars of the building constituent units 10a to 10d, are gathered and adjacent to each other. These four pillars 11a to 11d are connected by a connecting member (not shown). Ceiling beams 12a to 12d are joined to the upper side surfaces of the column heads of the columns 11a to 11d. The ceiling beams 12a to 12d are long bodies having a U-shaped cross section.

  Damping members 20a to 20d are arranged in the gaps between the column heads of the adjacent columns 11a to 11d. The damping members 20a to 20d are formed in a band shape (plate shape). The damping members 20a to 20d are members having damping performance. For the damping members 20a to 20d, for example, viscoelastic bodies are used. The damping members 20a to 20d exhibit a damping force when they are sheared by an earthquake force.

  Further, as shown in FIG. 1, the damping members 20a to 20d are arranged in the same manner not only in the gaps of the column heads of the columns 11a to 11d (see FIG. 2) but also in the column bases of the columns 11a to 11d. Yes. In FIG. 1, the skeletons such as the pillars 11 a to 11 d are omitted for easy understanding of the drawing.

  In the unit building 1, as shown in FIG. 1, only two pillars 11a, 11b,... Of the four pillars 11a to 11d (see FIG. 2) are gathered and adjacent to each other in the side wall portions A to D. As shown in FIG. 4, a damping member 20e is arranged in the gap between the heads of the two adjacent pillars 11a, 11b. In FIG. 4, the vibration damping member 20 e disposed between the pillars 11 a and 11 b is illustrated, but the vibration damping member 20 e is similarly disposed between the other two pillars as illustrated in FIG. 1. Yes. Moreover, the damping member 20f is also arranged in the gap between the column bases of the two columns 11a, 11b. In addition, the thing similar to the damping members 20a-20d is used for the damping members 20e and 20f.

  The vibration damping members 20a to 20f can be arranged simply by being inserted into the gaps between the column heads and the column bases of the columns 11a to 11d when the building configuration units 10a to 10d are arranged adjacent to each other. The damping members 20a to 20f sandwiched in the gaps between the pillars 11a to 11d exhibit a damping force by being deformed as dampers when the frames constituting the building constituting units 10a to 10d are deformed.

  As described above, in the present embodiment, when the building configuration units 10a to 10d are arranged adjacent to each other and connected to each other, the band-shaped damping members 20a to 20f are sandwiched between the pillars 11a to 11d. Therefore, it is easy to assemble a unit building with earthquake resistance.

  Thus, by improving the seismic performance of the unit building, the safety of the house can be enhanced even in the event of a large earthquake.

  Further, in this embodiment, in order to provide the unit building with earthquake resistance, a member for special attachment such as a reinforcing member or a connecting piece other than the vibration damping members 20a to 20f is not required, and therefore, the manufacturing cost. Will not increase.

  Furthermore, since the damping members 20a to 20f may be disposed in the gaps between the pillars 11a to 11d, a special arrangement location is not required.

  Moreover, the damping members 20a to 20f of the present embodiment can be easily attached.

  The present invention has been described with reference to the embodiment. However, the present invention is not limited to the above embodiment, and various modifications can be made. For example, in the present embodiment, the example in which the damping members 20a to 20f are arranged in the gaps between the two columns 11a, 11b,... Or the four columns 11a to 11d to be collected has been described. It is also possible to arrange a damping member in the gap.

  Further, in the present embodiment, the example in which the number of building configuration units 10a to 10d is four has been described. However, the number of building configuration units may be three or less, or may be five or more building configuration units. .

  In the present embodiment, a unit building having a structure consisting of only the first floor has been described. However, the present invention can also be applied to a unit building having a structure including two or more floors.

  In the present embodiment, the band-shaped damping members 20a to 20f have been described.

  Moreover, although this embodiment demonstrated the example which arrange | positions the damping members 20a-20f in the pillar head or pillar base of the pillars 11a-11d, you may arrange | position along the whole pillars 11a-11d.

  Moreover, although the example which arrange | positions damping member 20a-20f in all the clearance gaps of the four pillars 11a-11d was demonstrated in this Embodiment, it is not necessarily the damping member 20a-20f in the clearance gaps of all the pillars 11a-11d. Is not necessary, and the damping members 20a to 20f may be arranged in the gaps between some of the columns 11a to 11d.

  In the present embodiment, an example in which the cross section of the ceiling beams 12a to 12d is U-shaped has been described. However, the cross-section is not necessarily U-shaped, and the shape of the cross section is not limited. Moreover, the cross-sectional shapes of the pillars 11a to 11d may be any shape as long as the vibration damping members 20a to 20d can be disposed.
