  FIG. 6A is a schematic diagram illustrating a process of forming the second hole 12a in the lower structure 12.

  When the lower structure 12 is manufactured, the second hole 12a of the lower structure 12 is formed by placing concrete in a state where a mold frame (not shown) having the same shape as the second hole 12a is installed. The second hole 12 a is formed slightly larger than the cross-sectional shape of the cylindrical member 21. Note that the step of forming the second hole 12a of the lower structure 12 may be performed in advance at a factory or the like.

  FIG. 6B is a schematic diagram illustrating a process of installing the support member 4 on the bottom surface 12 c of the second hole 12 a of the lower structure 12.

  The support member 4 is installed according to the cross-sectional shape of the cylindrical member 21 and the bottom member 23. Note that the support member 4 does not need to be installed at the corners of the cylindrical member 21 and the bottom member 23, as long as the support member 4 can be supported.

  FIG. 6C is a schematic diagram illustrating a process of installing the base material 2 on the support member 4 on the lower structure 12.

  It is preferable that the lid member 22, the bottom member 23, and the insertion member 31 are attached to the cylindrical member 21 in advance by welding or the like at a factory or the like.

  FIG. 6 (d) is a schematic view showing a step of placing the outer hardening material 32 a inside the second hole 12 a of the lower structure 12 outside the cylindrical member 21.

  The outer hardening material 32 a is first injected into the second hole 12 a of the lower structure 12 outside the cylindrical member 21. When the outer hardening material 32a is filled to the same height as the upper surface 12b of the lower structure 12, the second hole 12a of the lower structure 12 may be closed by a lid or the like (not shown).

  FIG. 6E is a schematic view showing a process of placing the inner hardened material 32 b on the inner side of the cylindrical member 21.

  Then, the inner side hardening material 32b is inject | poured from the hole formed in the cover member 22 inside the cylinder member 21. FIG. The inner side hardening material 32 b is injected into the cylindrical member 21 until it becomes the same height as the upper end 21 a of the cylindrical member 21 and the lid member 22. And the movement limiting member 1 which has the base material 2, the reinforcement member 3, and the supporting member 4 is integrated.

  After the curing material 32 is cured, as shown in FIG. 1, the upper structure is manufactured on-site in the same shape as the cylinder member 21, with a large cylinder (not shown) installed with the gap between the movement restriction member 1 and the gap. Alternatively, the upper structure 11 is installed so that the upper side of the cylindrical member 21 is inserted into the first hole 11a of the upper structure 11. It is preferable that the first hole 11a has substantially the same cross-sectional shape with respect to the cross-sectional shape of the cylindrical member 21, and is formed slightly larger. Moreover, it is preferable that the lower structure 12 supports the upper structure 11 at other locations so that a vertical gap is formed between the first hole 11 a and the base material 2.

  Such a movement restricting member construction method allows easy construction in a short time.

  Next, the operation of the movement limiting member 1 will be described.

  When the upper structure 11 tries to move in the horizontal direction, a bending moment and a shearing force act on the movement limiting member 1 installed in the vertical direction as shown in FIG. When the moving distance of the upper structure 11 in the horizontal direction is increased, the cylindrical member 21 of the movement limiting member 1 is bent and deformed to absorb energy, attenuate the vibration of the upper structure 11, and reduce the movement. Is possible. Moreover, since the movement restricting member 1 has the insertion member 31 inside the base material 2 and injects the inner curing material 32b, the insertion member 31 restrains the inner curing material 32b inside the base material 2. Since it is united in a state where the holding force is increased, it is possible to delay the breakage and maintain the strength even if the cylindrical member 21 of the base material 2 undergoes a large deformation.

  In addition, by attaching the lid member 22 to the upper end of the cylindrical member 21, the inner surface of the cylindrical member 21 and the inner hardened material 32b can be integrated and reliably filled. Furthermore, when the movement restricting member 1 undergoes a large deformation, it is possible to restrain the hardened material 32 from popping out. In this way, the base material 2 and the reinforcing member 3 are strongly integrated and can have higher toughness. Further, since the insertion member 31 has a spiral shape, a commercially available spiral spring or the like can be used, and the cost can be reduced.

  Next, the movement restriction member 2 of the second embodiment will be described.

  FIG. 7 is a schematic view showing the movement restricting member 1 of the second embodiment according to the present invention. 8 is a cross-sectional view taken along the line VIII-VIII in FIG.

Further, the insertion member 31 may be attached to the lid member 22 by welding or the like. If the operation of attaching the insertion member 31 to the base material 2 is performed in advance in a factory or the like, work on site such as bridge construction can be reduced and workability can be improved.

  Further, the insertion member 31 may be attached so as to protrude from one end of the cylindrical member 21 in the longitudinal direction. One end of the cylindrical member 21 from which the insertion member 31 protrudes becomes the lower end 21b when it is installed in the lower structure 12.

  The insertion member 31 is attached so as to protrude from one end of the cylindrical member 21 in the longitudinal direction, thereby serving as a spacing member when the cylindrical member 21 is installed in the second hole 12a. It becomes easy to adjust.

  In addition, you may attach the insertion member 31 via a bracket etc., without attaching directly to the base material 2. FIG.

  As the curing material 32, an outer curing material 32a and an inner curing material 32b are used.

  FIG. 9A is a schematic view showing a process of forming the second hole 12a in the lower structure 12.

  When the lower structure 12 is manufactured, the second hole 12a of the lower structure 12 is formed by placing concrete in a state where a mold frame (not shown) having the same shape as the second hole 12a is installed. The second hole 12a has substantially the same cross-sectional shape with respect to the cross-sectional shape of the cylindrical member 21, and is formed slightly larger. Note that the step of forming the second hole 12a of the lower structure 12 may be performed in advance at a factory or the like.

  FIG. 9B is a schematic diagram illustrating a process of installing the base material 2 and the insertion member 31 on the lower structure 12.

  The base member 2 and the insertion member 31 are preferably attached in advance at a factory or the like by welding or the like. When installing the cylindrical member 21 and the insertion member 31 in the lower structure 12 at the construction site, the cylindrical member 21 is inserted into the second hole 12a with the side from which the insertion member 31 protrudes downward. In a state where the cylindrical member 21 and the insertion member 31 are installed in the lower structure 12, the insertion member 31 contacts the bottom of the second hole 12 a of the lower structure 12, and the cylindrical member 21 is in contact with the lower structure 12. And has a predetermined interval and does not contact.

  FIG. 9C is a schematic view showing a process of placing the outer hardened material 32 a inside the second hole 12 a of the lower structure 12 outside the cylindrical member 21.

  The curing material 32 firstly injects the outer curing material 32 a into the second hole 12 a of the lower structure 12 outside the cylindrical member 21. When the outer hardening material 32a is filled to the same height as the upper surface 12b of the lower structure 12, the second hole 12a of the lower structure 12 may be closed by a lid or the like (not shown).

  FIG. 10D is a schematic view showing a process of placing the inner hardened material 32 b on the inner side of the cylindrical member 21.

  Then, the inner side hardening material 32b is inject | poured from the hole formed in the cover member 22 inside the cylinder member 21. FIG. The inner side hardening material 32 b is injected into the cylindrical member 21 until it becomes the same height as the upper end 21 a of the cylindrical member 21 and the lid member 22. And the movement limitation member 1 which has the base material 2 and the reinforcement member 3 is integrated.

  After the hardened material 32 is cured, as shown in FIG. 8, the upper structure is manufactured on-site with the same shape as the cylindrical member 21 and a large cylinder (not shown) installed with the gap between the movement restricting member 1 and the gap. Alternatively, the upper structure 11 is installed so that the upper side of the tubular member 21 is inserted into the first hole 11 a of the upper structure 11. It is preferable that the first hole 11a has substantially the same cross-sectional shape with respect to the cross-sectional shape of the cylindrical member 21, and is formed slightly larger. Moreover, it is preferable that the lower structure 12 supports the upper structure 11 at other locations so that a vertical gap is formed between the first hole 11 a and the base material 2.

  Note that the step of forming the first hole 11a of the upper structure 11 may be performed in advance at a factory or the like. Further, a cushioning material or the like may be installed between the upper structure 11 and the cylindrical member 21.

  By such a construction method of the movement restriction structure, construction can be easily performed in a short time.

  Next, the operation of the movement limiting member 1 will be described.

  When the upper structure 11 is to move in the horizontal direction, a bending moment and a shearing force act on the movement limiting member 1 installed in the vertical direction as shown in FIG. When the moving distance of the upper structure 11 in the horizontal direction is increased, the cylindrical member 21 of the movement limiting member 1 is bent and deformed to absorb energy, attenuate the vibration of the upper structure 11, and reduce the movement. Is possible. Moreover, since the movement restricting member 1 has the insertion member 31 inside the base material 2 and injects the inner curing material 32b, the insertion member 31 restrains the inner curing material 32b inside the base material 2. Since it is united in a state where the holding force is increased, it is possible to delay the breakage and maintain the strength even if the cylindrical member 21 of the base material 2 undergoes a large deformation.

  In addition, by attaching the lid member 22 to the upper end of the cylindrical member 21, the inner surface of the cylindrical member 21 and the inner hardened material 32b can be integrated and reliably filled. Furthermore, when the movement restricting member 1 is largely deformed, it is possible to restrain the inner hardened material 32b from popping out. In this way, the cylindrical member 21, the insertion member 31, and the inner side hardening material 32b are strongly integrated and can have higher toughness.

Since the insertion becomes easy and the effect of the insertion member 31 restraining the inner side hardening material 32b on the inner side of the base material 2 is increased, the movement limiting member 1 can have higher toughness.

  In addition, you may change the number of the insertion members 31 and the attachment location with respect to the cylinder member 21. FIG. Moreover, when the cross-sectional shape of the cylindrical member 21 has no corners such as a circle, the cylindrical member 21 may be attached at any position without corresponding to the corners. However, when a plurality of insertion members 31 are installed, the insertion members 31 are preferably attached symmetrically with respect to the center of the cross section of the cylindrical member 21 so that force acts evenly.

Even if it is deformed, the strength can be maintained. Furthermore, by attaching the lid member 22 to the upper end of the cylindrical member 21, further integration of the base material 2 and the reinforcing member 3 can be achieved, and it becomes possible to reinforce appropriately. Further, when the movement restricting member 1 is greatly deformed, it is possible to restrain the reinforcing member 3 from popping out.
