  When the upper part of the first pillar receives a horizontal force and tries to rotate with respect to the lower part during an earthquake, the rotation is hindered by the first tubular member, and the lower end of the upper part and the lower part A relatively large bending moment acts on each of the upper ends of the portions. For this reason, the first pillar must bear the bending moment and is relatively large. When the upper part of the second pillar receives horizontal force and tries to rotate with respect to the lower part during an earthquake, the rotation is hindered by the second tubular member, and the lower end of the upper part and the lower part A relatively large bending moment acts on each of the upper ends of the portions. For this reason, the second pillar must bear the bending moment and is relatively large.

  Bending moment corresponding to the sum of the bending moment acting on the lower end of the upper portion and the bending moment acting on the upper end of the lower portion when the upper portion of the first column receives a horizontal force during an earthquake Acts on the one end of the beam. Since the bending moment acting on each of the lower end portion of the upper portion and the upper end portion of the lower portion is relatively large, the bending moment acting on the one end portion of the beam is relatively large. Bending moment corresponding to the sum of the bending moment acting on the lower end portion of the upper portion and the bending moment acting on the upper end portion of the lower portion when the upper portion of the second column receives a horizontal force during an earthquake Acts on the other end of the beam. Since the bending moment acting on each of the lower end portion of the upper portion and the upper end portion of the lower portion is relatively large, the bending moment acting on the other end portion of the beam is relatively large. For this reason, the beam must bear a relatively large bending moment and is relatively large. Thus, the building is uneconomical.

  An object of the present invention is a building including two piles provided in the ground at intervals, each extending upward from the ground, a beam between the piles, and a pillar member on each pile. The bending moment acting on each of the lower end portion of the column member and the upper end portion of the pile when the column member receives a horizontal force during an earthquake is compared with the bending moment acting on each end portion of the beam.

Since the bending moment acting on the lower end of the first column member is relatively small and the bending moment transmitted from the lower end of the first column member to the upper end of the first pile is relatively small, the one end of the beam The bending moment acting on is relatively small. Thereby, the bending moment which the said beam bears is comparatively small, and the said beam can be reduced in size.

  The second tubular member surrounding the upper end of the second pile below the second pillar member, the upper end surface of which is located at substantially the same height as the upper end surface of the second pile. Since the other end of the beam is coupled to a member, when the second column member receives a horizontal force and tries to rotate with respect to the second pile during an earthquake, the rotation is the second cylindrical shape. The bending moment acting on the lower end of the second column member is relatively small without being obstructed by the member, and the bending moment transmitted from the lower end of the second column member to the upper end of the second pile is relatively small. . Thereby, the bending moment which the said 2nd pile bears is comparatively small, and the said 2nd pile can be reduced in size.

  When the second column member receives the horizontal force, a bending moment corresponding to the sum of the bending moment acting on the lower end portion of the second column member and the bending moment acting on the upper end portion of the second pile is Acts on the other end of the beam. Since the bending moment acting on the lower end of the second column member is relatively small and the bending moment transmitted from the lower end of the second column member to the upper end of the second pile is relatively small, the other end of the beam The bending moment acting on the part is relatively small. Thereby, the bending moment which the said beam bears is comparatively small, and the said beam can be reduced in size.

So that it is at the same height as

  When attaching the 1st cylindrical member 28 to the upper end part 18 of the 1st pile 14, the 1st cylindrical member 28 is arrange | positioned on the 1st annular plate 44, and the 1st cylindrical member 28 and the upper end of the 1st pile 14 A first filler 46 is filled between the portions 18. When attaching the 2nd cylindrical member 30 to the upper end part 20 of the 2nd pile 16, the 2nd cylindrical member 30 is arrange | positioned on the said 2nd annular plate, The upper end of the 2nd cylindrical member 30 and the 2nd pile 16 The second filler is filled between the portions 20.

  After the attachment of the first tubular member 28 to the upper end 18 of the first pile 14 and the attachment of the second tubular member 30 to the upper end 20 of the second pile 16, the upper end 18 of the first pile 14 and the first The lower beam 22 is disposed between the upper end 20 of the two piles 16, and one end 32 of the lower beam is attached to the first tubular member 28 and the other end 34 is attached to the second tubular member 30. . The attachment of the one end portion 32 of the lower beam 22 to the first tubular member 28 is performed by connecting the one end portion 32 of the lower beam 22 to the bracket 28a of the first tubular member 28, and the second tubular member. The other end 34 of the lower beam 22 is attached to 30 by connecting the other end 34 of the lower beam 22 to the bracket of the second tubular member 30.

  In addition, after arrange | positioning the lower beam 22 between the upper end part 18 of the 1st pile 14, and the upper end part 20 of the 2nd pile 16, the one end part 32 of this lower beam is made into the 1st cylindrical member 28, others. Instead of the above example of attaching the end 34 to the second tubular member 30 respectively, before placing the lower beam 22 between the upper end 18 of the first pile 14 and the upper end 20 of the second pile 16, The first tubular member 28 may be attached to one end 32 of the lower beam 22, and the second tubular member 30 may be attached to the other end 34 of the lower beam 22. In this case, when the lower beam 22 is disposed between the upper end 18 of the first pile 14 and the upper end 20 of the second pile 16, the first tubular member 28 surrounds the upper end 18 of the first pile 14. The second tubular member 30 surrounds the upper end 20 of the second pile 16.

  A lower beam 22 is disposed between the upper end 18 of the first pile 14 and the upper end 20 of the second pile 16, and one end 32 of the lower beam is used as the first tubular member 28 and the other end 34. Are attached to the second cylindrical member 30, the first pillar member 24 is disposed on the first pile 14, and the second pillar member 26 is disposed on the second pile 16, respectively. An upper beam 36 spaced from the lower beam 22 is disposed between the second column member 26. When the first pillar member 24 is disposed on the first pile 14, first, the first pillar member 24 is disposed from above the first pile 14, and the first through holes 58 of the first base plate 60 are disposed with the first bolts 54.

  Since the first base plate 60 of the first pillar member 24 has a plurality of first through holes 58 each receiving a first bolt 54 attached to the first closing plate 50 of the first pile 14, When the first pillar member 24 is lowered from above until each first through hole 58 receives the first bolt 54, the first pillar member 24 is disposed at a predetermined position with respect to the first pile 14. be able to. For this reason, the first pillar member can be efficiently arranged at the predetermined position without adjusting the position of the first pillar member 24 with respect to the first pile 14.

  Since the second base plate of the second column member 26 has a plurality of the second through holes each receiving the second bolt attached to the second closing plate of the second pile 16, When the second pillar member 26 is lowered from above until each second through hole receives the second bolt, the second pillar member 26 is disposed at a predetermined position with respect to the second pile 16. Can do. For this reason, the second pillar member can be efficiently arranged at the predetermined position without adjusting the position of the second pillar member 26 with respect to the second pile 16.

Since the first cylindrical member 28 does not restrain the first column member 24 and the first column member 24 receives a horizontal force during an earthquake, the first cylindrical member 28 receives the horizontal force against the first pile 14. When attempting to rotate, the rotation is not hindered by the first tubular member 28. Thereby, the bending moment which acts on each of the lower end part 56 of the 1st pillar member 24 and the upper end part 18 of the 1st pile 14 at the time of an earthquake is comparatively small, and the 1st pile 14 can be reduced in size.

A moment acts on one end 32 of the lower beam 22. Since the bending moment acting on each of the lower end portion 56 of the first column member 24 and the upper end portion 18 of the first pile 14 is relatively small, the bending moment acting on the one end portion 32 of the lower beam 22 is relatively small. Each of the beam 22 and the first cylindrical member 28 can be reduced in size.

  The second cylindrical member 30 surrounding the upper end 20 of the second pile 16 below the second pillar member 26 and the upper end surface of which is located at substantially the same height as the upper end surface of the second pile 16 is arranged in addition to the lower beam 22. Since the end portion 34 is attached, the second cylindrical member 30 does not restrain the second column member 26, and the second column member 26 receives a horizontal force and rotates relative to the second pile 16 during an earthquake. When trying to do so, the rotation is not hindered by the second tubular member 30. Thereby, the bending moment which acts on each of the lower end part of the 2nd pillar member 26 and the upper end part 20 of the 2nd pile 16 at the time of an earthquake is comparatively small, and the 2nd pile 16 can be reduced in size.

  When the second column member 26 receives the horizontal force, the bending moment corresponding to the sum of the bending moment acting on the lower end portion of the second column member 26 and the bending moment acting on the upper end portion 20 of the second pile 16 Acts on the other end 34 of the lower beam 22. Since the bending moment acting on each of the lower end portion of the second column member 26 and the upper end portion 20 of the second pile 16 is relatively small, the bending moment acting on the other end portion 34 of the lower beam 22 is relatively small. Each of the beam 22 and the second cylindrical member 30 can be reduced in size.

  The lower beam 22 extends to the first tubular member 28 that surrounds the upper end 18 of the first pile 14 below the first pillar member 24 and whose upper end surface 48 is located at substantially the same height as the upper end surface 42 of the first pile 14. Since the one end portion 32 is coupled, when a horizontal force acts on the lower beam 22 during an earthquake, the horizontal force is transmitted to the first pile 14 without passing through the first column member 24. Thereby, the 1st pillar member 24 can be prevented from bearing the said horizontal force, and the 1st pillar member 24 can be reduced in size. In addition, the lower beam 22 surrounds the second cylindrical member 30 that surrounds the upper end portion 20 of the second pile 16 below the second pillar member 26 and whose upper end surface is substantially at the same height as the upper end surface of the second pile 16. Therefore, when a horizontal force acts on the lower beam 22 during an earthquake, the horizontal force is transmitted to the second pile 16 without passing through the second column member 26. Thereby, the 2nd pillar member 26 can be prevented from bearing the said horizontal force, and the 2nd pillar member 26 can be reduced in size.
