  On the ground, the wall connecting device having such a configuration is such that a left frame member is attached to the outside of one inner member, a left landing member is attached to the left frame member, and a right frame member is attached to the outside of the other inner member. A right landing member is attached to the frame member.

  Then, by operating the tower crane, one of the inner member, the left frame member, and the left landing member is lifted and positioned at a predetermined position of the mast, and the load receiving member of the one inner member is used as the cross member of the mast. The inner member, the left frame member, and the left landing member are fixed at the positions by being locked to the upper portion of the inner member.

  Then, by operating the tower crane, the other inner member, the right frame member, and the right landing member are lifted and positioned at a predetermined position of the mast, and the load receiving member of the other inner member is used as the cross member of the mast. The other inner member, the right frame member, and the right landing member are fixed at the positions by being locked to the upper portion of the inner member.

  Then, by inserting a connecting pin between one end of the left frame member and the right frame member and between the other end, the one end and the other end of the left frame member and the right frame member are connected to form a rectangular frame shape. A plurality of stay members are bridged between the left and right frame members of the frame member and the building frame, and both ends of each stay member are fixed to the left frame member, the right frame member, and the frame side. By connecting via pins, the frame member is supported on the housing side via a plurality of stay members.

  In this way, the wall joining device can be attached to a predetermined height of the mast, and at that position, the mast can be supported on the housing side via the wall joining device. On the other hand, when removing the wall connecting device from the mast, the above procedure is followed in reverse.

  As shown in FIG. 13, the left landing member 66 and the right landing member 67 can relatively rotate a fixed side member 68 and a movable side member 69 that are L-shaped in plan view via a hinge (not shown). One end of the fixed side member 68 of the left landing member 66 and the fixed side member 68 of the right landing member 67 are connected to each other via a hinge so as to be relatively rotatable.

  The fixed side member 68 and the movable side member 69 of the left landing member 66 and the right landing member 67 are, as shown in FIGS. 13 and 14, a bottom plate 70 having a predetermined width and length in a plan view, and inside and outside of the bottom plate 70. It is composed of a handrail 71 erected vertically over the entire length at the edge, and cylindrical suspension column support portions 72 provided at a plurality of locations at predetermined intervals along the entire length of the inner edge of the bottom plate 70. Yes.

  The left landing member 66 and the right landing member 67 are each provided with a suspension column 73 between each suspension column support portion 63 of the left frame member 42 and each suspension column support portion 72 of the left landing member 66, and the right frame member 43. The suspension column 73 is attached to the left frame member 42 and the right frame member 43 by attaching the suspension column 73 between each suspension column support portion 63 and each suspension column support portion 72 of the right landing field member 67.

  The left landing member 66 and the right landing member 67 are configured to be able to rotate following the left frame member 42 and the right frame member 43, and follow the movable side member 50 of the left frame member 42 and the right frame member 43. The movable member 69 of the left landing member 66 and the right landing member 67 is configured to be rotatable.

  In order to support the mast 80 on the housing by the wall joining device 1 of the present embodiment configured as described above, first, the left frame member 42 is bolted and nuted on the outside of one inner member 2 on the ground. The left landing member 66 is attached to the left frame member 42 via the suspension pillar 73, the right frame member 43 is attached to the outside of the other inner member 3 via bolts and nuts, and the suspension pillar is attached to the right frame member 43. A right landing member 67 is attached via 73.

  Next, the connecting plate 56 of the fixed side member 44 of the left frame member 42 and the connecting plate 56 of the fixed side member 44 of the right frame member 43 are overlapped, and between the pin insertion holes 56a, 56a of both the connecting plates 56, 56. By inserting the connecting pin 63 into the first pin coupling portion 57, the fixed side member 44 of the left frame member 42 and the fixed side member 44 of the right frame member 43 are connected so as to be relatively rotatable. Furthermore, the fixed side member 68 of the left landing member 66 and the fixed side member 68 of the right landing member 67 are connected to each other via a hinge (not shown) so as to be relatively rotatable.

  Next, a suspension jig 87 is attached to the hook 86 of the tower crane 85, the wall joining device 1 is suspended on the suspension jig 87, and the tower crane 85 is operated, so that the wall joining device 1 is attached to the lower end of the mast 80. Move to the side (see FIG. 16). In addition, in FIG. 16, the wall joining apparatus 1 is arrange | positioned at the lower end of a mast, and after setting to the lower end of a mast, the process in the middle of raising along a mast is shown.

  Here, as shown in FIG. 16, the hanging jig 87 is formed in a plan view gate shape, so that the hanging point of the hanging jig 87 by the tower crane 85 and the hanging of the wall joining apparatus 1 by the hanging jig 87 are suspended. The point is decentered by a predetermined distance in the horizontal direction, and by using this hanging jig 87, the wall connecting device 1 is raised and lowered along the mast 80 in a state where both the hanging points are decentered. Can do.

  When the wall connecting device 1 is disposed on the side of the lower end of the mast 80, the left frame member 42 and the right frame member 43 of the frame member 41 are connected to the first pin coupling portion 57 as shown in FIG. By rotating in the direction of arrows A and B in the figure around the center, the one inner member 2 and the other inner member 3 are slightly opened, and the second pin coupling With the portion 61 as the center, the movable side member 50 is rotated and opened in the direction of the arrow C in the figure with respect to the fixed side member 44 of the left frame member 42, and further, with the third pin coupling portion 62 as the center, The movable side member 50 is rotated in the direction of arrow D in the figure to the open state with respect to the fixed side member 44 of the right frame member 43, and the mast 80 is placed between the inner members 2 and 3 from the side of the mast 80. It should be in a state where it can be inserted.

  Then, by operating the tower crane 85, as shown in FIGS. 15 (b) and 15 (c), the mast 80 is inserted between the inner members 2, 3 of the wall connecting device 1 from the side, The inner members 2 and 3 are made to correspond to the two opposing side surfaces, and in this state, the left frame member 42 and the right frame member 43 are relatively rotated in the closing direction around the first pin coupling portion 57, and The movable side member 50 is rotated relative to the fixed side member 44 of the left frame member 42 in the closing direction around the second pin coupling portion 61, and the right frame member 43 is centered around the third pin coupling portion 62. The movable side member 50 is rotated relative to the fixed side member 44 in the closing direction, so that the vertical members 4, 4 of the inner members 2, 3 are placed on the outer surfaces of both main members 82 on each side surface of the mast 80. Correspondingly, the guide rod of each inner member 2, 3 The peripheral surface of the roller of La 15 into contact with the outer surfaces of the main member 82 of each side of the mast 80.
