Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a braced structure of a building such as a building and a pier.
[0002]
[Prior art]
As shown in FIG. 6, the bracing forms a rigid structure by inserting a member 3 in a diagonal direction at a connecting portion between the column 1 and the cross member 2.
[0003]
[Problems to be solved by the invention]
According to such a braced structure, when a repeated impact load such as an earthquake is applied to the member, an impact load is generated in the member because tension and compression act alternately. As a result, there is a problem that the member is damaged at the mounting position.
[0004]
[Means for Solving the Problems]
Therefore, the present invention embeds a chain body in a support made of an elastic body, interposes a support between the rings, and extends a ring at the end to outside the support to constitute a cushioning material. It is characterized in that it is attached to the end of a member that is bent or between members.
According to such a configuration, the tensile force and the compressive force acting on the member can be absorbed by the cushioning material, and the structure becomes an earthquake-resistant structure.
[0005]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
First Embodiment FIG. 1 is an explanatory view showing a bracing structure, and FIG. 2 is a side view of a cushioning material. In the drawing, reference numeral 4 denotes a support made of an elastic body such as natural rubber, synthetic rubber, or synthetic resin. Is a chain body buried in the support 4 and is a combination of metal rings. The ring 6 and the ring 7 are interposed between the support 4 and the ring 7 and the ring 7. The support 4 is also interposed, and the end of each ring 7 is protruded outside the support 4 or connected to a connector 8 outside the support 4 as shown in the drawing to form a cushioning material 9.
[0006]
The connector 8 has a shape adapted to the shape, structure or material of the member 10 to be connected, and may have any shape as long as it can be firmly fixed to the end of the member 10. Or any shape such as a protrusion of a locking ring as shown in the figure.
As shown in the figure, the cushioning member 9 is formed by interposing a connection portion between the column 1 and the cross member 2 in a diagonal direction at the end of the member 10 or between the members via the ring 7 or the connector 8. It is.
[0007]
According to the braced structure configured as described above, when a tensile force acts on the member 3, a and b of the support 4 of the cushioning material 9 are compressed, c is pulled, and when a compressive force acts on the member 3. , B, c are compressed. In this way, it has a buffer function against both the compressive force and the tensile force, and a buffer effect is obtained against a repeated load such as an earthquake.
Second Embodiment In the first embodiment described above, a cushioning material having a buffering effect in two directions has been described, but a cushioning material having a buffering effect in two or more directions is also conceivable. Therefore, the present embodiment shows a case where it is possible to cope with four directions. FIG. 3 is an explanatory view showing the bracing structure, and FIG. 4 is a side view of the cushioning material. In the drawing, 4 is a support made of an elastic body such as natural rubber, synthetic rubber, or synthetic resin, and 11 is this support. A chain body buried in the body, which is a combination of metal rings. The ring 12 and each of the rings 13 arranged in four directions are interposed between the ring 13 and the ring 13 with the support 4 interposed therebetween. The support member 4 is interposed between the support member 13 and the end portion of each ring 13 so as to protrude outside the support member 4 or is connected to a connector 14 outside the support member 4 as shown in the drawing to form a cushioning material 15. I have.
[0008]
The connector 14 has a shape adapted to the shape, structure or material of the member 10 to be connected, and may have any shape as long as it can be firmly fixed to the member 10. It may be of any shape, such as one with a locking ring protruding as shown.
As shown in the figure, the cushioning member 15 is provided such that the connecting portion between the column 1 and the cross member 2 is interposed via a ring 13 or a connector 14 at an intersection of the members 10 in which diagonal directions are inserted.
[0009]
According to the braced structure thus configured, when a compressive force (tensile force) acts on the member 10 in the direction A in the figure, a tensile force (compressive force) acts on the member B in the direction B. Therefore, when a compressive force acts in the direction A, a buffering effect can be obtained with respect to the tensile force in the directions b, c, and B, respectively.
FIG. 5 is a graph showing the relationship between the force and the amount of displacement in each of the above embodiments in comparison with the conventional example.
[0010]
In each of the above embodiments, the case where one ring is disposed in the support is illustrated and described. However, the present invention is not limited to a single ring. May be done. In each case, a support is interposed between the rings.
[0011]
【The invention's effect】
According to the present invention described in detail above, a chain body is embedded in a support made of an elastic body, a support is interposed between the rings, and a ring at the end is taken out of the support to constitute a cushioning material. By attaching the cushioning material to the ends of the braced members or between the members, it is possible to buffer the tensile force and the compressive force acting on the members, and to obtain an excellent seismic structure.
