Description

  The present invention is used, for example, in a base-isolated structure of a building, and is used for a joint between an H-section steel and a H-section steel, or a joint between a bracing and a H-section steel. For example, the present invention relates to a seismic isolation damper test fixture for absorbing shock caused by shaking such as an earthquake, and a test apparatus using the seismic isolation damper test fixture.

  More specifically, such a seismic isolation damper has a structure as shown in FIG.

  That is, as shown in the perspective view of FIG. 7, the seismic isolation damper 100 includes a rectangular inner plate-like body 102 made of, for example, a steel plate. A pair of rectangular rubber members 104 composed of elastic seismic isolation rubber is provided.

  Further, a pair of outer plate-like bodies 106 are provided outside these rubber members 104. Further, as shown in FIG. 7, one end portion 108 a of the inner plate-like body 102 is longer in the longitudinal direction than one end portion 104 a of the rubber member 104 and one end portion 106 a of the outer plate-like body 106. It has a protruding structure. A plurality of mounting bolt holes 110 are provided in one fixing projection 108 of the inner plate-like body 102.

  On the other hand, the other end portion 106 b of the outer plate-like body 106 has a structure protruding in the longitudinal direction from the other end portion 102 b of the inner plate-like body 102 and the other end portion 104 b of the rubber member 104. A plurality of mounting bolt holes 114 are provided in the other fixing protrusion 112 of the outer plate-like body 106.

  For the seismic isolation damper 100 having such a structure, for example, a test apparatus as disclosed in Patent Document 1 (Japanese Patent Laid-Open No. 2005-3379), Patent Document 2 (Japanese Patent Laid-Open No. 2003-207430), and the like is used. Then, mounting bolts are attached to the plurality of mounting bolt holes 110 of the protruding portion 108 of the inner plate-like body 102 and fixed to one gripping portion of the test apparatus, and the fixing protrusion 112 of the outer plate-like body 106 is fixed. A mounting bolt is attached to the plurality of mounting bolt holes 114 and fixed to the other gripping portion of the test apparatus, and a test such as a vibration test is performed.

Japanese Patent Laid-Open No. 2005-3379 Japanese Patent Laid-Open No. 2003-207430

  By the way, in the seismic isolation damper 100 having such a structure, the thickness of the rubber member 104 is not uniform due to variations in processing accuracy, and therefore, the pair of outer plate-like bodies 106 may not be parallel.

  For this reason, in the seismic isolation damper 100 having such a structure, a shift in the thickness direction of FIG. 7 (the direction of the arrow A, that is, the separation distance direction) may occur. For example, although not shown in the drawing, the pair of outer plate-like bodies 106 may have an eight-shaped shape or an inverted eight-shaped shape in a sectional view.

  Further, in the seismic isolation damper 100 having such a structure, a shift in the twist direction (arrow B direction) in FIG. 7 and a shift in the rotation direction (arrow C direction) in FIG. 7 may occur.

  For this reason, when it is going to pinch and fix with respect to the seismic isolation damper 100 which produced such a shift | offset | difference, these shift | offset | difference of the seismic isolation damper 100 may be corrected.

  Thus, if the test is performed in a state where these deviations of the seismic isolation damper 100 are corrected (corrected) with the mounting jig, the test data is far from the actual test result of the seismic isolation damper 100, and the test data is accurate. The test cannot be performed.

  For this reason, in the conventional test apparatus, as described in Patent Document 1, such a deviation of the seismic isolation damper 100 is corrected by sandwiching a correction member such as a shim material or a gap gauge between mounting jigs. Is to prevent.

  However, it is necessary to prepare shim materials having a plurality of dimensions and shapes depending on the size and type of the deviation of the seismic isolation damper 100, and use them alone or in combination. This requires a lot of work, takes time and effort, and increases test costs.

  In view of the current situation, the present invention does not correct the displacement of the seismic isolation damper, and the seismic isolation damper can be fixed to the test fixture while the seismic isolation damper is displaced. A test using a seismic isolation damper test fixture and a test using a seismic isolation damper test fixture that can perform an accurate test without being far from test data of the seismic isolation damper An object is to provide an apparatus.

  In addition, the present invention eliminates the need for conventional compensation members such as shim materials and gap gauges, can reduce costs and labor, and can be easily attached to a test fixture with a seismic isolation damper. To provide a test fixture using a seismic isolation damper test fixture and a test fixture using a seismic isolation damper test fixture, in which non-linear factors due to rattling do not affect test results. Objective.

The present invention was invented in order to achieve the problems and objects in the prior art as described above, and the seismic isolation damper test fixture of the present invention comprises:
A test fixture for a seismic isolation damper comprising an inner plate, a pair of rubber members provided on both sides of the inner plate, and a pair of outer plates provided outside the rubber member. There,
A pair of fixing jig members that are erected on a base plate and arranged in a state of being separated from each other, and configured to sandwich and fix a fixing protrusion of an outer plate-like body of the seismic isolation damper;
Each of the fixing jig members is

An inner diameter X1 of the fastening bolt hole is configured to be larger than an outer dimension X2 of the fastening bolt,
An inner diameter dimension Y1 of the pressure nut is configured to be larger than an outer dimension Y2 of the jig support attached through the pressure nut.

  With this configuration, the fixing member is rotatably mounted on the jig main body portion via the rotation shaft, so that the fixing member rotates about the rotation shaft.

  Thereby, when a shift in the thickness direction of FIG. 7 (the direction of the arrow A, that is, the separation distance direction) occurs, for example, in a cross-sectional view, the pair of outer plate-like bodies 106 has an eight-shaped shape, The state which became the shape of a reverse octagon can be absorbed.

  In addition, a fastening bolt hole is formed in the fixing member so as to correspond to the mounting bolt hole formed in the fixing protrusion of the outer plate-like body of the seismic isolation damper.

  Since the inner diameter dimension X1 of the fastening bolt hole is larger than the outer dimension X2 of the fastening bolt and has a clearance, the shift in the rotational direction (arrow C direction) in FIG. 7 is absorbed. be able to.

  Furthermore, since the dimension Y1 of the inner diameter of the pressure nut is larger than the dimension Y2 of the outer shape of the jig support attached via the pressure nut and has a clearance, the twist direction of FIG. It is possible to absorb the deviation between the arrow B direction and the arrow A direction.

  Therefore, the seismic isolation damper 100 is not corrected, and the seismic isolation damper 100 can be fixed to the test fixture while the seismic isolation damper 100 is displaced. It is possible to perform an accurate test without having test data far from the results.

  In addition, there is no need for conventional correction members such as shim materials and gap gauges, which can reduce costs and labor, and it is easy to mount the seismic isolation damper 100 on the test fixture, resulting in variations in mounting accuracy. In addition, non-linear factors due to rattling do not affect the test results.

  Thereby, when the shift | offset | difference of the thickness direction (arrow A direction) of FIG. 7 arises, for example, a pair of outer side plate-like body 106 becomes a figure-eight shape by a cross sectional view, or a reverse figure-eight shape. The absorbed state can be absorbed.

  In addition, a fastening bolt hole is formed in the fixing member so as to correspond to the mounting bolt hole formed in the fixing protrusion of the outer plate-like body of the seismic isolation damper.

  Since the inner diameter dimension X1 of the fastening bolt hole is larger than the outer dimension X2 of the fastening bolt and has a clearance, the shift in the rotational direction (arrow C direction) in FIG. 7 is absorbed. be able to.
