Japanese Patent Laid-Open No. 10-18620 JP-A-4-47032

  By the way, since the roof of a structure is generally constructed at a high place on a pillar or a vent (temporary support column), there is a possibility that the construction may take time.

  In consideration of the above facts, an object of the present invention is to improve the workability of a roof.

  The structure construction method according to claim 1 includes a roof construction step of laying a roof between supports that do not bear earth pressure after the structure is completed, and a structure under the roof while supporting the roof with the support. An internal space forming step of removing the earth and sand to form an internal space.

  According to the structure construction method of the first aspect, in the roof construction process, the roof is constructed between the supports that do not bear earth pressure after the structure is completed. Next, in the internal space forming step, the inner space is formed by removing the earth and sand under the roof while supporting the roof with the support.

  Here, when the earth and sand under the roof is not removed, the support height of the support body that supports the roof is increased according to the required height of the internal space.

  On the other hand, in the present invention, since the inner space is formed by removing earth and sand under the roof, the support height of the support body that supports the roof can be lowered. Thereby, since a roof can be constructed in a low place, the workability of the roof is improved.

  In addition, after building the roof, the earth and sand under the roof is removed to form an internal space. Therefore, the internal space can be formed without being influenced by the weather (for example, rain, snow, strong wind, etc.).

  Further, the support that supports the roof does not bear earth pressure after the structure is completed. Therefore, for example, the workability of the support is improved as compared with the case where the roof is supported by a retaining wall that bears earth pressure after the structure is completed.

  The construction method according to claim 2 is the construction method according to claim 1, wherein in the roof construction step, the roof is constructed between the foundations as the support, and the internal space formation step. The inner space is formed by digging a ground below the roof.

  According to the construction method of the structure according to claim 2, in the roof construction process, the roof is constructed between the foundations that do not bear earth pressure after the structure is completed. Therefore, for example, a roof can be laid. Therefore, the workability of the roof is improved.

  Next, in the internal space formation step, the ground under the roof is dug down while the roof is supported by the foundation to form the internal space. That is, in the present invention, at least a part of the internal space is formed underground by digging the ground. Thereby, compared with the case where the ground under a roof is not dug down, the support height of a support body can be made low. Therefore, since a roof can be constructed in a low place, the workability of the roof is improved.

  The construction method of the structure according to claim 3 includes a roof construction step of constructing a roof along an inclined ground, and a lower end side in the inclination direction of the roof upward with an upper end side in the inclination direction of the roof as a rotation center. A roof erection step for moving and supporting the lower end side with a support, and an internal space forming step for forming an internal space by digging the ground under the roof while supporting the lower end side of the roof with the support. .

  According to the construction method of the structure according to claim 3, the roof is constructed along the inclined ground in the roof construction step. That is, in this invention, a roof is constructed in a low place. Therefore, the workability of the roof is improved.

  Next, in the roof erection process, the lower end side of the roof inclination direction is moved upward with the upper end side of the roof inclination direction as the center of rotation, and the lower end side is supported by the support. Next, in the internal space forming step, the ground under the roof is dug down while supporting the lower end side of the roof with the support to form the internal space.

  Thus, in the present invention, in the roof erection process, the lower end side of the roof inclination direction and the inclined ground are moved upward by moving the lower end side of the roof inclination direction upward with the upper end side of the roof inclination direction as the rotation center. An internal space is formed between the two. Therefore, the amount of excavation of the ground under the roof can be reduced in the internal space forming step. Therefore, the workability is improved.

  As described above, according to the construction method for a structure according to the present invention, the workability of the roof can be improved.

  Hereinafter, a construction method for a structure according to an embodiment of the present invention will be described with reference to the drawings. In addition, below, the construction method of the stadium as a structure is demonstrated as an example.

  First, the first embodiment will be described.

  As shown in FIG. 1 (A), first, in the support construction process, after completion of the stadium 10 (after completion), a pile 20 that does not bear earth pressure is constructed on the ground 12.

  Specifically, in the outer periphery of the stadium 10 as a structure, a plurality of piles 20 that respectively support the both sides in the material axis direction of the roof beam 32 constituting the roof 30 (see FIG. 1B) are provided on the ground 12. Form. At this time, the head 20A of the pile 20 is protruded from the ground 12A. In the present embodiment, the ground surface 12A is a flat surface. The roof beam 32 is a truss beam.

  Various piles, such as a concrete pile and a steel pile, can be used for the pile 20 as an example of a support body. Moreover, a support body is not restricted to the pile 20 (pile foundation). The support may be anything that does not negatively apply earth pressure (no burden in design) after completion of the stadium 10, such as an independent foundation, a cloth foundation, a pillar 24 (see FIG. 2B) described later, and the like. There may be. The support does not include a retaining wall that negatively applies earth pressure after completion of the stadium (structure) 10.

  Next, as shown in FIG. 1B, in the roof construction process, the roof 30 is laid between the heads 20A of the piles 20 located on both sides (outer periphery) of the stadium 10. Specifically, roof beams 32 constituting the roof 30 are respectively installed between the heads 20A of the piles 20 located on both sides of the stadium 10, and roof materials such as folded plates (not shown) are provided on these roof beams 32. ). At this time, the roof beam 32, the roof material, and the like are assembled in a low place near the ground 12A.

  In addition, in this embodiment, although the head 20A of the pile 20 protruded from the ground 12A, it is not restricted to this. For example, a base such as a footing may be formed on the head 20A without projecting the head 20A of the pile 20 from the ground 12A, and the roof beam 32 may be installed on the foundation.

  Next, as shown in FIG. 1 (C), in the internal space forming step, while supporting the roof 30 with the plurality of piles 20, the ground 12 under the roof 30 is dug into a concave shape to form the internal space 14. To do. That is, while supporting the roof 30 with the plurality of piles 20, the internal space 14 is formed by removing earth and sand under the roof 30. At this time, for example, the ground 12 under the roof 30 may be excavated and earthed from the outer periphery of the roof 30, or the roof 30 may be partially opened and excavated and earthed from this opening. .

  The excavation bottom surface 12B of the ground 12 is a flat surface, and a field 40A (see FIG. 1D) described later is formed on the excavation bottom surface 12B. Further, the excavation side surface 12C surrounding the excavation bottom surface 12B of the ground 12 is formed into an inclined surface (slope) by an open cut method (legged open cut method) or the like, and a spectator seat 44 (see FIG. D) See).

  Next, as shown in FIG. 1D, while using the excavation bottom surface 12B and the excavation side surface 12C as a formwork (ground mountain formwork) in the spectator seat building process, the excavation bottom surface 12B and the excavation side surface 12C are used. The concrete plates 40 and 42 are respectively formed along the. Then, on the concrete board 40, for example, a natural turf or artificial turf (not shown) is laid to form a field 40A for performing various competitions and events. On the other hand, on the concrete board 42 formed in the outer peripheral part of the field 40A, for example, a staircase-shaped auditorium 44 is constructed.

  Next, effects of the first embodiment will be described.

  According to the construction method of the structure according to the present embodiment, the roof 30 is installed between the piles 20 located on the outer peripheral portion of the stadium 10 in the roof construction process. Next, in the internal space forming step, the ground 12 under the roof 30 is dug down while the roof 30 is supported by the plurality of piles 20 to form the internal space 14.

  Here, when the ground 12 under the roof 30 is not dug down, the internal space 14 is formed on the ground, so the support height of the support that supports the roof 30 according to the required height of the internal space 14. Becomes higher.

  On the other hand, in this embodiment, the ground 12 under the roof 30 is dug down to form at least a part of the internal space 14 in the basement. Thereby, since the support height of the pile 20 which supports the roof 30 on the ground can be made low, the roof 30 can be grounded in the low place near the ground 12A. Therefore, the workability of the roof 30 is improved.

  In addition, after the roof 30 is constructed, the internal space 14 is formed regardless of the weather (for example, rain, snow, strong wind, etc.) in order to form the internal space 14 by digging the ground 12 under the roof 30. Can do. Therefore, it is possible to improve the workability and shorten the construction period.

  Furthermore, by using the excavation side surface 12C of the ground 12 as an inclined surface, collapse of the excavation side surface 12C is suppressed. Therefore, a retaining wall or the like that suppresses collapse of the excavation side surface 12C or the like can be eliminated.

  In addition, in the present embodiment, the spectator seat 44 is constructed using the inclined excavation side surface 12C, so that the frame work for the spectator seat 44 is reduced. Therefore, the workability of the spectator seat 44 is improved.

  Further, the pile 20 that supports the roof 30 does not bear earth pressure after the stadium 10 is completed. Therefore, for example, the workability of the pile 20 is improved as compared with the case where the roof 30 is supported by a retaining wall that bears earth pressure after completion of the stadium 10.

  Furthermore, in this embodiment, the ground 12 under the roof 30 is dug down to form the internal space 14, so that the stadium 10 can be easily disassembled. That is, when the stadium 10 is dismantled, for example, the spectator seat 44, the concrete plates 40, 42, and the like are crushed and removed by a crusher or the like. Next, the internal space 14 is backfilled while being compacted. Thereafter, the roof 30 and the pile 20 are dismantled and removed.

  By refilling the internal space 14 in this manner, the roof 30 can be dismantled at a low place near the ground 12A. Therefore, the work efficiency of the dismantling work of the roof 30 is improved. Furthermore, if the spectator seats 44 and the piles 20 and the like can be left in the ground, the dismantling and removal work of the spectator seats 44 and the piles 20 and the like is not necessary, so that the stadium 10 is further easily disassembled.

  In particular, this embodiment is suitable for a temporary stadium 10. In other words, when the stadium 10 is temporary, the excavated soil of the ground 12 is temporarily placed in a temporary place near the stadium 10. When the stadium 10 is dismantled, the internal space 14 is backfilled with excavated soil temporarily placed in the temporary place. This eliminates the need for disposal of the excavated soil and reduces the cost for transporting the excavated soil.

  Next, a second embodiment will be described. In addition, the thing of the same structure as 1st Embodiment attaches | subjects the same code | symbol, and abbreviate | omits description.

  In the said 1st Embodiment, although the roof 30 was constructed on the pile 20 as a support body in a roof construction process, as shown in FIG. 2 (A)-FIG. 2 (D) in 2nd Embodiment. In the roof construction process, the roof 30 is installed on the pillar 24 as a support.

Form a part of That is, while supporting the roof 30 with the plurality of pillars 24, the inner space 14 is expanded by removing the earth and sand under the roof 30. In addition, when the temporary support | pillar 24 is installed, the temporary support | pillar 24 is removed suitably.

  At this time, the excavation bottom surface 12B of the ground 12 is a flat surface, and the excavation side surface 12C is an inclined surface (slope). Further, the excavated soil is raised on the ground surface 12 </ b> A of the outer peripheral portion of the excavation concave portion obtained by dug the ground 12 into a concave shape to form the embankment portion 16. The embankment side 16A on the inner space 14 side (excavation recess side) in the embankment 16 is an inclined surface continuous with the excavation side 12C. A step may be formed between the embankment side surface 16A and the excavation side surface 12C.

  Next, as shown in FIG. 2 (D), while using the excavation bottom surface 12B, the excavation side surface 12C, and the embankment side surface 16A as a formwork (natural ground formwork) in the audience seat construction process, Concrete boards 40 and 42 are formed along 12B, excavation side surface 12C, and embankment side surface 16A, respectively. And the spectator seat 44 is constructed | assembled on the concrete board 42 formed in the outer peripheral part of the field 40A.
