Even if it acts on the side wall, the first to fourth The wall is not inadvertently deformed, and the foundation structure with the deformed shapes of the first to fourth side walls is not distorted, and the foundation structure as designed according to the calculated structure is constructed at the installation location. be able to. In the foundation structure installation method, the adjustment bolt, the third long nut, the third width stop bolt, the fourth long nut, and the fourth width stop bolt are integrated with the hardened cement material after the curing period of the hardened cement material has elapsed. Since the load applied to the substructure is shared by the adjusting bolt, the third long nut, the third width retaining bolt, the fourth long nut, the fourth width retaining bolt, and the cemented cured product, The foundation structure can be firmly installed at the installation location, and heavy machinery and equipment such as solar panels, antennas, water storage tanks, septic tanks, air conditioners, and heavy buildings such as steel towers, steel columns, and steel structures A substructure that can be reliably supported can be constructed. In the substructure installation method, the distance between the first and third side walls can be finely adjusted with the third width stop bolt, and the distance between the second and fourth side walls can be finely adjusted with the fourth width stop bolt. Therefore, even if the separation dimension of the first and third sidewalls and the separation dimension of the second and fourth sidewalls are slightly different from the design dimension, the separation dimension can be made to match the design dimension. It is possible to build a normal foundation structure.

  A bottom frame material is formed from the first to fourth bottom frame materials, and in the bottom frame material installation step, the first bottom frame material is fixed to the bottom of the first side wall, and the second bottom frame material is attached to the bottom of the second side wall. The first to fourth bottom frame materials are manufactured in the foundation structure installation method of fixing and fixing the third bottom frame material to the bottom of the third side wall and fixing the fourth bottom frame material to the bottom of the fourth side wall. Since it is manufactured at the factory and is made into general-purpose parts, the bottom frame material is completed simply by installing these bottom frame materials on the bottom of the first to fourth side walls of the foundation pipe according to the manualized procedure. There is no need to assemble the formwork at the bottom or dismantle the formwork, and it is possible to save labor, time and cost for assembling the formwork or disassembling the formwork. Since the foundation structure installation method can simplify the installation work of the bottom frame member, the foundation structure can be quickly installed at the installation location, and the construction period of the foundation structure can be greatly shortened. In the foundation structure installation method, the first to fourth bottom frame members block the gap between the first to fourth side walls and the casing, and therefore, it is possible to prevent moisture from entering the inner space from the bottom of the foundation pipe. It is possible to prevent deterioration of the casing due to the ingress of moisture.

  The bottom portion is formed of the first to fourth bottom portions, and the adjustment bolt is installed on the first adjustment bolt installed on the first bottom portion, the second adjustment bolt installed on the second bottom portion, and the third bottom portion. The foundation structure installation method formed from the third adjustment bolt and the fourth adjustment bolt installed on the fourth bottom portion adjusts the height and inclination of the base pipe with respect to the frame by the first to fourth adjustment bolts. Therefore, even if the installation location is inclined, the foundation pipe can be installed horizontally with respect to the installation location, and when multiple foundation structures are installed, the height of the foundation structures can be increased. The height dimensions can be easily adjusted, and the height dimensions of these substructures can be made uniform. The foundation structure installation method is manualized because the foundation pipe is fixed to the installation location by the first to fourth adjustment bolts installed in the bolt holes formed in the first to fourth bottom portions and the bolt holes of the housing. The foundation pipe can be easily fixed to the frame in accordance with the procedure, and the construction period of the foundation structure can be greatly shortened. In the foundation structure installation method, since the first to fourth adjustment bolts are installed in the bolt holes of the housing, even if the side pressure of the cement hardened material placed in the inner space acts on the first to fourth side walls, The first to fourth adjustment bolts fixed to the housing prevent inadvertent deformation of the first to fourth side walls due to the side pressure of the hardened cement, and the deformed shape of the first to fourth side walls is distorted. Can be constructed, and a foundation structure as designed can be constructed at the installation location.

There is no need to dismantle, while adjusting the height and inclination of the base pipe relative to the housing using the adjustment bolt while fixing the base pipe to the installation location, and installing the width stop bolt on the first to fourth side walls, By installing the bottom frame material and the top frame material on the base pipe and placing the hardened cement in the inner space, the foundation structure can be installed at the installation location. Time-consuming and time to dismantling, it is possible to save the cost. The foundation structure installation method not only simplifies the installation work of the foundation structure, but also completes the installation work of the new waterproofing material without waiting for the curing period of the hardened cement, and the curing period of the hardened cement Since the installation work of the foundation structure is completed without waiting for the installation time, the curing time of the hardened cement material does not enter the installation time of the foundation structure, and multiple foundation structures can be quickly installed at the installation location. It can be greatly shortened. The foundation structure installation method can significantly shorten the construction period of the foundation structure, and can greatly reduce the labor cost for building the foundation structure, thus reducing the cost of installing the foundation structure. The foundation structure can be constructed at a low cost. In the foundation structure installation method, it is not necessary to assemble the formwork at the installation site on the construction site, and the foundation structure can be assembled according to a manual procedure. Can be easily constructed. In the foundation structure installation method, the adjustment bolt is screwed into the bolt hole formed in the frame, the foundation tube is fixed to the frame by the adjustment bolt, and the adjustment bolt is cemented after the curing period of the cement hardened material has passed. Since the load applied to the foundation structure is shared by the adjustment bolt and the hardened cement material, the foundation structure can be firmly installed at the predetermined installation location of the existing building's housing. It is possible to build a foundation structure that can reliably support heavy machinery such as antennas, water storage tanks, septic tanks, air conditioners, and heavy buildings such as steel towers, steel columns, and steel structures. . In the foundation structure installation method, even if the side pressure of the hardened cement placed in the inner space acts on the first to fourth side walls of the base pipe, the width retaining bolts installed in the base pipe Since the deformation of the first to fourth side walls is prevented, the base structure with the deformed shape of the first to fourth side walls is not formed, and the foundation structure as designed as the structure is calculated at the installation location. Can be built. In the foundation structure installation method, the height and inclination of the foundation pipe relative to the frame can be adjusted by adjusting bolts, so even if the installation location is inclined, the foundation pipe should be installed horizontally with respect to the installation location. In addition, when a plurality of foundation structures are installed, the height dimensions of the foundation structures can be easily adjusted, and the height dimensions of the foundation structures can be made uniform.

  Before the cement hardened material placing step, the cement hardening includes a support bolt installation step in which a support bolt having a screw upper portion extending upward from the top frame member and a screw lower portion extending downward from the top frame member is installed on the top frame member. When the hardened cement material is placed in the inner space by the object placing step, the upper part of the screw of the support bolt is exposed upward from the hardened cement material, and the lower part of the screw of the support bolt is buried in the hardened cement material. Heavy equipment such as solar panels, antennas, water storage tanks, septic tanks, air conditioning equipment, steel towers, steel columns, steel structures, etc., are firmly fixed to the support bolts exposed upward from the hardened cement. By using the support bolts, it is possible to construct a foundation structure that can firmly attach these machinery and equipment to the foundation structure. Can.

  In the support bolt installation process, a spacer installed on the top frame material and a bolt positioning member installed on the spacer and spaced upward from the top frame material so that the support bolt can be inserted and removed are used. The bolt positioning member and the spacer removing process for removing the bolt positioning member and the spacer from the top frame material after curing the hardened cement material is performed by installing the spacer on the top frame material and installing the support bolt. After installing the bolt positioning member on the spacer, placing the cement hardened material in the inner space, curing the hardened cement material, and removing the bolt positioning member and the spacer, the lower part of the screw of the support bolt is Since the upper part of the screw of the support bolt is exposed upward from the hardened cement, it is fixed to the hardened cement. By using the member, the screw lower part of the support bolt can be easily installed in the fixed position of the cement hardened material positioned accurately, and the screw upper part of the support bolt is exposed upward from the cement hardened material. Can do. The foundation structure installation method consists of supporting bolts exposed upward from the hardened cement, and heavy equipment such as solar panels, antennas, water storage tanks, septic tanks, air conditioners, steel towers, steel columns, and steel structures. A certain building can be firmly fixed, and by using a support bolt, it is possible to construct a foundation structure capable of firmly mounting those machinery and equipment and the building on the foundation structure.

  The top portion is formed from the first to fourth top portions, the top frame material is formed from the first to fourth top frame materials, and the first top frame material can be attached to and detached from the first top portion in the top frame material installation step. Install, detachably install the second top frame member on the second top portion, detachably install the third top frame member on the third top portion, and detach the fourth top frame member on the fourth top portion The foundation structure installation method that can be installed is that the first to fourth top frame materials are manufactured at the manufacturing plant and are made into general-purpose parts (standardized), and the top frame materials are installed in the base pipe according to the manualized procedure. Since the top frame material can be assembled simply by installing it at the first to fourth top parts, there is no need to assemble the formwork on the top of the base pipe or dismantle the formwork, The time, cost and cost for dismantling can be saved. Since the foundation structure installation method can simplify the installation work of the top frame member, the foundation structure can be quickly installed at the installation location, and the construction period of the foundation structure can be greatly shortened.

  After the width stop bolt installation step and before the cement hardened material placement step, the width stop bolt is used to finely adjust the distance between the first and third side walls and the distance between the second and fourth side walls. In the substructure installation method including the first adjustment step of the separation dimension for finely adjusting the distance, the separation dimension of the first and third sidewalls and the separation of the second and fourth sidewalls by the width stop bolt before the cement hardened material placing step Since the dimensions can be finely adjusted, even if the separation dimensions of the first and third sidewalls and the separation dimensions of the second and fourth sidewalls are slightly different from the design dimensions, the separation dimensions are made to match the design dimensions. It is possible to construct the foundation structure according to the design dimensions.

  In the setting process of the hardened cement material, the distance between the first and third side walls is finely adjusted and the distance between the second and fourth side walls is finely adjusted using the width stop bolt. In the substructure installation method including the second adjustment step of the separation dimension, the side pressure of the hardened cement material acts on the first and third side walls and the second and fourth side walls in the process of placing the hardened cement material in the inner space. Even if the separation dimension of the side walls changes, the separation dimension of the first and third sidewalls can be finely adjusted by the width retaining bolt, and the separation dimension of the second and fourth sidewalls can be finely adjusted by the width retaining bolt. Therefore, the separation dimension of the side walls can be matched with the design dimension, and the substructure according to the design dimension can be constructed.

  The substructure installation method in which the deformation of the first and third side walls and the deformation of the second and fourth side walls due to the lateral pressure of the hardened cement material placed in the inner space is prevented by the width stop bolt is applied to the inner space. Since the deformation of the first and third side walls due to the side pressure of the hardened cement can be prevented by the width stop bolt, the side pressure of the hardened cement placed in the inner space acts on the first to fourth side walls. Even if it does, the 1st-4th side wall will not change carelessly, the shape which the 1st-4th side wall deformed will not make the distorted foundation structure, and the structure calculation was carried out to the installation location. A foundation structure as designed can be constructed.

  New waterproof material installation process is performed before cement hardened material placing process or after cement hardened material placing process, and installation work of new waterproof material without waiting for curing period of cement hardened material placed in inner space As for the foundation structure installation method, the installation work of the new waterproofing material is completed and the installation work of the installation foundation structure is completed without waiting for the curing period of the hardened cement material. Therefore, the curing time of the hardened cement does not enter the installation time of the foundation structure, multiple foundation structures can be quickly installed at the installation location, and the construction period of the foundation structure can be greatly shortened. The labor cost for constructing the structure can be greatly reduced. As a result, the cost for installation of the foundation structure can be reduced, and the foundation structure can be constructed at a low cost.

  In the new waterproof material installation process, the foundation structure is installed by extending the new waterproof material in the radial direction from the bottom frame material and covering the frame located around the bottom frame material with the new waterproof material. Even when installed on the roof of an object, since the frame located around the bottom frame material is covered with the newly installed waterproof material, water can be prevented from entering the foundation tube, the bottom frame material, and the frame. Corrosion and strength reduction of the base pipe and the bottom frame material due to water entering the bottom frame material can be prevented, and deterioration of the frame due to water entering the frame can be prevented.

  A first long nut fixed to the inner wall surfaces of the first and third side walls in the center portion of the base tube and a second long nut fixed to the inner wall surfaces of the second and fourth side walls in the center portion of the base tube The base structure installation is formed of a first width-stopping bolt screwed to the first long nut and a second width-stop bolt screwed to the second long nut. The method prevents the first and third side walls from being deformed by the lateral pressure of the hardened cement cemented with the first width stop bolt screwed to the first long nut, and screwed to the second long nut. Since the second width retaining bolt that has been formed prevents the deformation of the second and fourth side walls due to the lateral pressure of the hardened cement placed in the inner space, the lateral pressure of the hardened cement placed in the inner space is the first to the second. Even if it acts on the fourth side wall, The 4 side walls are not inadvertently deformed, and the foundation structure with the deformed shape of the first to fourth side walls is not distorted. can do. In the foundation structure installation method, the adjustment bolt, the first long nut, the first width stop bolt, the second long nut, and the second width stop bolt are integrated with the hardened cement material after the curing period of the hardened cement material has elapsed. Since the load applied to the substructure is shared by the adjustment bolt, the first long nut, the first width retaining bolt, the second long nut, the second width retaining bolt, and the hardened cement, the predetermined structure of the existing building The foundation structure can be firmly installed at the installation location, and heavy equipment such as solar panels, antennas, water storage tanks, septic tanks, air conditioning equipment, heavy towers, steel pillars, steel constructions A substructure that can be reliably supported can be constructed. In the substructure installation method, the first and third side walls can be finely adjusted with the first width stop bolt, and the second and fourth side walls can be finely adjusted with the second width stop bolt. Therefore, even if the separation dimension of the first and third sidewalls and the separation dimension of the second and fourth sidewalls are slightly different from the design dimension, the separation dimension can be made to match the design dimension. It is possible to build a normal foundation structure.

  A third long nut fixed to the inner wall surface of the first and third side walls at the top of the base tube and a fourth long nut fixed to the inner wall surface of the second and fourth side walls at the top of the base tube The substructure installation method is formed of a third width stop bolt formed and a width stop bolt screwed to the third long nut and a fourth width stop bolt screwed to the fourth length nut. The third width stop bolt screwed to the third long nut prevented the deformation of the first and third side walls due to the side pressure of the hardened cement placed in the inner space, and was screwed to the fourth long nut. Since the fourth width stop bolt prevents the deformation of the second and fourth side walls due to the lateral pressure of the hardened cement material placed in the inner space, the lateral pressure of the hardened cement material placed in the inner space is the first to fourth. Even if it acts on the side wall, the first to fourth The wall is not inadvertently deformed, and the foundation structure with the deformed shapes of the first to fourth side walls is not distorted, and the foundation structure as designed according to the calculated structure is constructed at the installation location. be able to. In the foundation structure installation method, the adjustment bolt, the third long nut, the third width stop bolt, the fourth long nut, and the fourth width stop bolt are integrated with the hardened cement material after the curing period of the hardened cement material has elapsed. Since the load applied to the substructure is shared by the adjusting bolt, the third long nut, the third width retaining bolt, the fourth long nut, the fourth width retaining bolt, and the cemented cured product, The foundation structure can be firmly installed at the installation location, and heavy machinery and equipment such as solar panels, antennas, water storage tanks, septic tanks, air conditioners, and heavy buildings such as steel towers, steel columns, and steel structures A substructure that can be reliably supported can be constructed. In the substructure installation method, the distance between the first and third side walls can be finely adjusted with the third width stop bolt, and the distance between the second and fourth side walls can be finely adjusted with the fourth width stop bolt.

A bottom frame material is formed from the first to fourth bottom frame materials, and in the bottom frame material fixing step, the first bottom frame material is fixed to the bottom of the first side wall, and the second bottom frame material is attached to the bottom of the second side wall. The first to fourth bottom frame materials are manufactured in the foundation structure installation method of fixing and fixing the third bottom frame material to the bottom of the third side wall and fixing the fourth bottom frame material to the bottom of the fourth side wall. Since it is manufactured at the factory and is made into general-purpose parts, the bottom frame material is completed simply by installing these bottom frame materials on the bottom of the first to fourth side walls of the foundation pipe according to the manualized procedure. There is no need to assemble the formwork at the bottom or dismantle the formwork, and it is possible to save labor, time and cost for assembling the formwork or disassembling the formwork. Since the foundation structure installation method can simplify the installation work of the bottom frame member, the foundation structure can be quickly installed at the installation location, and the construction period of the foundation structure can be greatly shortened. In the foundation structure installation method, the first to fourth bottom frame members block the gap between the first to fourth side walls and the casing, and therefore, it is possible to prevent moisture from entering the inner space from the bottom of the foundation pipe. It is possible to prevent deterioration of the casing due to the ingress of moisture.

  The bottom portion is formed of the first to fourth bottom portions, and the adjustment bolt is installed on the first adjustment bolt installed on the first bottom portion, the second adjustment bolt installed on the second bottom portion, and the third bottom portion. The foundation structure installation method formed from the third adjustment bolt and the fourth adjustment bolt installed on the fourth bottom portion adjusts the height and inclination of the base pipe with respect to the frame by the first to fourth adjustment bolts. Therefore, even if the installation location is inclined, the foundation pipe can be installed horizontally with respect to the installation location, and when multiple foundation structures are installed, the height of the foundation structures can be increased. The height dimensions can be easily adjusted, and the height dimensions of these substructures can be made uniform. The foundation structure installation method is manualized because the foundation pipe is fixed to the installation location by the first to fourth adjustment bolts installed in the bolt holes formed in the first to fourth bottom portions and the bolt holes of the housing. The foundation pipe can be easily fixed to the frame in accordance with the procedure, and the construction period of the foundation structure can be greatly shortened. In the foundation structure installation method, since the first to fourth adjustment bolts are installed in the bolt holes of the housing, even if the side pressure of the cement hardened material placed in the inner space acts on the first to fourth side walls, The first to fourth adjustment bolts fixed to the housing prevent inadvertent deformation of the first to fourth side walls due to the side pressure of the hardened cement, and the deformed shape of the first to fourth side walls is distorted. Can be constructed, and a foundation structure as designed can be constructed at the installation location.
