The frame 20 is divided into a first block 20A, a second block 20B, a third block 20C, a fourth block 20D, and a fifth block 20E in the horizontal direction, with one span of the beams 22 and 26 as one block. ing.

  The support member 32 has a configuration in which a fluororesin-based coating having a low friction coefficient is applied to the bottom surface of a substantially cylindrical elastic member made of rubber.

  FIG. 2 shows an arrangement state of the rails 32 for moving each block constituting the housing 20 from the temporary gantry 36 (see FIG. 1) onto the preset support member 12 (see FIG. 1). Yes. The rail 32 is a stainless plate fixed on the slab 16, and a support material 30 is placed on the upper surface of the rail 32. In addition, the rail 32 is removed after moving the housing 20 on the support member 12, and is not included in the completed building 10 (see FIG. 1).

  Next, the construction procedure of the building 10 will be described.

  As shown in FIG. 3A, first, in the planned construction area of the building 10, the ground 11 is excavated while avoiding the existing railway T, and concrete is hit to form a pile portion 12A, which is precast on the pile portion 12A. A plurality of support members 12 are erected on the ground 11 by installing the pillar portion 12B made of metal.

  Subsequently, a temporary gantry 36 is constructed using steel and concrete in an area adjacent to the construction planned area of the building 10. The height of the temporary gantry 36 is the same as that of the upper surface of the support member 12, and the width of the temporary gantry 36 is about one span of the beam 14 (see FIG. 1).

  Subsequently, as shown in FIG. 3 (b), on the temporary gantry 36, the precast pillar 18 is erected and the beams 22 and 26 are erected, and concrete is laid to slab 24 and the ceiling portion 28. Form and build a first block 20A that is part of the enclosure 20.

  Subsequently, the rail 32 is attached on the temporary gantry 36 in the direction of the arrow X, and a plurality of support members 30 are arranged on the rail 32, and then the first block 20A is lifted by a crane (not shown) and mounted on the support member 30. Then, the support member 30 is fixed to the lower surface of the column 18 by welding or bolt fastening. Thereby, the first block 20A can move in the arrow X direction.

  Subsequently, the crane 40 is installed on the ceiling portion 28 of the first block 20A. Then, a precast beam 14 (for one span) is installed between the plurality of support members 12 using the crane 40, and both ends of the beam 14 are joined to the support member 12. Place concrete and so on. Thereby, the slab 16 for 1 span is formed in the moving direction (arrow X direction) of the first block 20A. After the slab 16 is formed, a rail 32 is attached to the upper surface of the slab 16 and connected to the rail 32 on the temporary gantry 36.

  Subsequently, when the first block 20A is pushed out in the direction of arrow X using a hydraulic jack (not shown) provided on the temporary gantry 36, the support member 30 moves so as to slide on the rail 32, and the first block 20A is temporarily installed. Move from the gantry 36 to the rail 32 on the slab 16.

  Here, as shown in FIG. 3C, the movement of the first block 20 </ b> A is temporarily stopped before the first block 20 </ b> A finishes moving by one span of the beam 14. Then, the beam 14 is installed between the plurality of support members 12 one block ahead using the crane 40, and concrete is placed to form the slab 16, and the rail 32 is attached to the upper surface of the slab 16. Thereafter, the first block 20A is moved again, and the movement is stopped when the span of the beam 14 is moved by one span.

  Subsequently, as shown in FIG. 4A, on the temporary gantry 36, the precast pillar 18 is erected and the beams 22 and 26 are erected to construct the second block 20B which is a part of the housing 20. To do. Then, after arranging a plurality of support members 30 on the rails 32 of the temporary gantry 36, the second block 20B is lifted by a crane (not shown) and placed on the support member 30, and the support member 30 is placed on the lower surface of the column 18. Secure by welding or bolt fastening.

  Subsequently, one end of the beams 22 and 26 of the second block 20B is joined to the column 18 of the first block 20A, and concrete is placed on the beams 22 and 26 to form the slab 24 and the ceiling 28. . Thereby, the first block 20A and the second block 20B are integrated.

  Subsequently, as shown in FIGS. 4B and 4C, similarly to the construction process of the first block 20A and the second block 20B, the beam 14 is installed between the plurality of support members 12 one block ahead. Forming the slab 16 and attaching the rail 32, moving the integrated block (a part of the housing 20), constructing the next block on the temporary construction base 36, and integrating the moved block. The process is repeated to construct and move the third block 20C, the fourth block 20D, and the fifth block 20E. Thereby, the first block 20A to the fifth block 20E (the casing 20) are arranged on the support member 12.

  Subsequently, as shown in FIG. 4C, the temporary base 36, the support member 12, and the rail 32 on the slab 16 are removed in a state where each column 18 is pushed upward using a hydraulic jack (not shown). Then, the hydraulic jack is lowered to place the support member 30 and the column 18 on the support member 12, and the support member 30 is fixed to the support member 12 by welding or bolt fastening. In this way, the building 10 shown in FIG. 1 is constructed without affecting the existing railway T.

  Next, the operation of the embodiment of the present invention will be described.

  As shown in FIG. 5, in the middle of the moving construction method of the housing 20 (here, the first block 20A and the second block 20B), a plurality of supports ahead of one block to which the rails 32 are not yet attached using the crane 40. The beam 14 is installed between the members 12, concrete is placed to form the slab 16, and the rail 32 is attached to the upper surface of the slab 16, and then the housing 20 is moved.

  Thus, since the slab 16 is formed prior to the movement of the casing 20, and the slab 16 covers the movement path of the casing 20 (the area through which the casing 20 passes in plan view, the lower side of the casing 20). Falling objects on the lower side during the movement of the housing 20 can be prevented, and the safety of the installation site of the housing 20 surrounded by the support member 12 can be ensured. In particular, when a railway T or a road is provided adjacent to the movement path of the chassis 20 or adjacent to the movement path, the safety of passage of the railway T, automobiles, and pedestrians can be ensured. Further, since the slab 16 can be used as a work floor (a place where a jack or temporary material is installed, a worker's scaffolding, a passage, or the like), the workability of moving the housing 20 is improved.

  Furthermore, since the housing 20 is constructed and moved one block at a time, the formation of the preceding slab 16 and the construction of the next block on the temporary gantry 36 can be performed in parallel, and work efficiency is improved. Further, since each block is constructed, the distance between the crane 40 and the place where the beam 14 is erected by the crane 40 is reduced, and it is possible to work with the small crane 40. In addition, since each divided block is lighter than the housing 20, it is not necessary to use a large-sized moving device, and the device cost for moving can be reduced.

  In addition, this invention is not limited to said embodiment.

  As shown in FIG. 6, the rail 32 is attached to the lower surface of each block (here, the first block 20A to the fourth block 20D) constituting the housing 20, and the support member 30 is attached on the support member 12 and the temporary construction base 36. Thus, the integrated blocks may be moved in the arrow X direction. When the lower part of the pillar 18 is weak in structure, the temporary beam 42 may be installed between the pillars 18 before the rail 32 is attached.

  Regarding the formation of the destination slab 16, not only the beam 14 is installed on the support member 12 and then the concrete is placed, but also the precast slab may be attached after the beam 14 is installed. A beam slab unit in which 14 and the slab 16 are integrated may be attached to the support member 12.
