Description

[Technical Field]

[0001] The present invention relates to a vibration-damping plate material and a building with improved vibration-damping properties. [Background technology]

[0002] Traditionally, development has been carried out to improve earthquake resistance as a measure against the frequent occurrence of earthquakes, but in recent years, it has become increasingly important to have vibration control properties in addition to earthquake resistance, which can reduce the shaking of buildings caused by earthquakes.

[0003] Patent Document 1 describes the configuration of a vibration-control building in which dampers with energy absorption mechanisms are installed between building materials such as beams and columns, and the relative displacement that occurs between the building materials during an earthquake is used to deform the dampers, thereby absorbing seismic energy.

[0004] Patent document 1: Patent No. 3988811

[0005] However, the structure described in Patent Document 1 had the problem that when vibrations that cause small relative displacements between building materials during an earthquake occur, the damper may not be able to deform sufficiently, and may not be able to absorb enough seismic energy.

DETAILED DESCRIPTION OF THE INVENTION [Example]

[0019] A first embodiment of the present invention will be described with reference to Figs. 1 to 3. Fig. 1 is a diagram illustrating a vibration-damping plate according to the first embodiment of the present invention. Fig. 2 is a diagram illustrating the vibration-damping plate according to the first embodiment of the present invention attached to a pillar or the like of a building. Fig. 3 is a cross-sectional view of the vibration-damping plate according to the first embodiment of the present invention attached to a pillar or the like of a building.

[0020] (Vibration-damping plate material) As shown in Fig. 1, the vibration-damping plate 100 in Example 1 comprises a face material 1, such as a fireproof board, and an elastic material 2, made of an elastic material such as vulcanized rubber, having approximately the same dimensions and shape as the face material 1, which is bonded to the face material 1 with an adhesive 3 so that the two face each other. The adhesive 3 is applied over a predetermined width around the entire edge of the faces where the face material 1 and the elastic material 3 face each other. The predetermined width in Example 1 is approximately the same as the width dimensions of the lower cross member, upper cross member, and pair of columns described below, but is not limited to this and can be changed as appropriate. In other words, the width may be larger or smaller than the width dimensions of the lower cross member, upper cross member, and pair of columns.

[0021] The adhesive 3 is applied with a predetermined width around the entire periphery of the opposing surfaces of the face material 1 and the elastic material 3, so that the elastic material 2 can effectively damp the vibrations it receives.

[0022] (Installation of vibration-damping plates on buildings) As shown in Fig. 2, the vibration-damping plate 100 is attached to one side of the space partitioned by the lower cross member 13, upper cross member 11, column 12, and column 14 of the building using adhesive 17 and fasteners 16 such as screws or nails. As shown in the AA' cross section and BB' cross section in Fig. 2 (see Fig. 3), the adhesive 17 is applied over a predetermined width around the entire periphery of the end of the expansion member 2 of the vibration-damping plate 100.

[0023] The adhesive 17 is applied over the entire periphery of the stretchable material 2 with a predetermined width, so that the stretchable material 2 can effectively damp the vibrations it receives.

[0024] Thus, in Example 1, a vibration-damping plate material used in a building is The surface material and and an elastic material having substantially the same dimensions and shape as the face material, a vibration-damping plate material in which the face material and the elastic material face each other and are bonded together in a region of a predetermined width around the entire periphery of the end portion; As a result, a large elastic material with approximately the same area as the face material is adhered to the entire periphery of the face material, so that vibrations can be received over the entire surface, and vibration damping can be achieved for both small and large vibrations. [Example]

[0025] Example 2 of the present invention differs from Example 1 in that slits are provided in the elastic material. Example 2 will be described with reference to Figs. 4 and 5. Fig. 4 is a diagram showing a vibration-damping plate according to Example 2 of the present invention attached to a pillar or the like of a building. Fig. 5 is a diagram explaining a preferred example in which a vibration-damping plate according to Example 2 of the present invention is attached to a pillar or the like of a building.

[0026] The vibration-damping plate 200 in Example 2 has an elastic member 202 that has approximately the same dimensions and shape as the face plate 1 shown in Fig. 4 and has multiple slits 209. The slits 209 are repeatedly provided over the entire surface of the elastic member 202, except for a predetermined width portion around the entire periphery of the end where the adhesive 3 and adhesive 17 are applied.

[0027] The slits 209 are provided so as to extend obliquely downward when the vibration-damping plate 200 is attached to the lower cross member 13, the upper cross member 11, the columns 12, and the columns 14 of the building. This makes it possible to effectively damp vibrations caused by earthquakes and the like.

[0028] Furthermore, when installing this vibration-damping plate 200 on a building, as shown in Figure 5, by installing two vibration-damping plates 200 on the left and right sides with the slits 209 of each plate slanted in opposite directions, vibrations can be effectively damped even if the direction of vibrations is complex.

[0029] That is, the slits 209 in the two vibration-damping plates 200 attached on the left and right are formed such that one runs from the upper right to the lower left, and the other runs from the upper left to the lower right.

[0030] In this way, in Example 2, by providing a plurality of slits in the elastic material, the range of motion of the elastic material is widened, and the vibration damping effect can be increased. [Example]

[0031] Example 3 of the present invention differs from Examples 1 and 2 in that vibration-damping plates are provided on both sides of a space partitioned by a lower cross member, an upper cross member, and a pair of columns of a building. Example 3 will be described with reference to Fig. 6. Fig. 6 is a diagram showing vibration-damping plates in Example 3 of the present invention attached to columns of a building, etc.

[0032] In Example 3, as shown in FIG. 6, a vibration-damping plate 100 is attached to one side of the space partitioned by the lower cross member, upper cross member, and pair of columns of the building using adhesive 17 and fasteners 16, and a vibration-damping plate 300 is attached to the other side using adhesive 317 and fasteners 316.

[0033] Similar to adhesive 17, adhesive 317 is applied over a predetermined width around the entire periphery of the end of stretchable material 302. This allows stretchable material 302 to effectively damp vibrations that it receives.

[0034] In this way, in Example 3, by providing vibration-damping plates on both sides of the lower cross member, the upper cross member, and the space partitioned by a pair of columns, higher vibration-damping properties can be obtained. [Industrial Applicability]

[0035] The vibration-damping plate and building of the present invention can be widely used in the field of vibration-damping structures against earthquakes. [Explanation of symbols]
