Description

  The present invention relates to a foundation post installed in a ground structure.

  The following is an example of the foundation of a field solar panel mount as a structure.

  The foundations of the conventional solar panel bases in the field are roughly divided into two types, one is concrete foundation and the other is support foundation.

  To create a foundation using concrete, various operations such as leveling, excavation, residual soil treatment, rebar processing, formwork installation, concrete placement, formwork dispersion, and backfilling are necessary. A so-called wood screw type that narrows in the direction of the lower tip. A spiral screw is provided in the length direction, resulting in a large amount of processing and excavation residual soil corresponding to the volume of the strut. In addition, there is a problem that it takes both cost and construction period.

  The foundation strut of the present invention uses a pipe as a foundation for installing a field structure, and cuts out a part of a donut-like plate having a shape larger than the diameter of the pipe for excavating earth and sand at one end. Attach a spiral plate with drilling teeth that bends in a triangular shape on one of the cut plates, and attach a flange for ground structure connection to the other end of the pipe. Has a plurality of mounting holes, and using these mounting holes, an attachment for connecting the rotating part at the tip of the hydraulic motor and the upper flange can be attached and rotated to dig into the ground. A doubling plate that can be moved up and down and mounted on top of each other is also attached, and it is intended to provide a foundation strut that enables various adjustments in the direction and level of the structure installed on the foundation strut. It is.

  According to the present invention, even if there is unevenness on the slope or the ground, it is possible to shorten the work period with simple construction by simply screwing it into the ground, and the excavation blades have a wide bottom effect, providing support force and passive excavation blades The resistance force becomes the pulling support force, and the flange can be used in combination with the ground structure joint plate, and it can be diversified. It has a simple structure with a flange at the top and drilling blades at the bottom. It can be recycled and no backfill is required.

The basic support of the present invention will be described below.
Fig. 1 uses a pipe as a foundation for installing a field structure and cuts out a part of a donut-shaped plate having a shape larger than the diameter of the pipe at one end to excavate earth and sand. One side of the pipe is attached to the pipe with a spiral plate formed with a digging tooth that bends in a triangular shape, and the other end of the pipe is attached to a flange for joining the ground structure. It is an overall view of the foundation strut that has a mounting hole and that can be attached to the rotating part at the tip of the hydraulic motor and the upper flange by using this mounting hole and rotated to dig into the ground. is there.
FIG. 3 shows a spiral plate in which a portion of a donut shape having a shape larger than the diameter of the pipe is cut out and excavating teeth that are bent in a triangular shape are formed on one side of the cut plate when viewed from below. FIG.

  FIG. 4 shows an attachment 10 used to connect the rotating portion 12 at the tip of the hydraulic motor 11 and the flange 4 provided on the support column. As for the connection method, a flange 13 having the same size as the flange 4 of the support column 1 is fastened with a bolt, and a shaft 14 that can be connected to the rotating portion 12 of the hydraulic motor 11 is provided on the upper portion of the flange 13. Stop with safety pin 15 to prevent.

  After the support column 1 is pushed into the ground to a predetermined level, when the attachment 10 connected to the hydraulic motor 11 is removed, the flange 4 of the support column 1 appears, and in order to install a stand of solar panels on the flange 4 Requires a doubling plate 30 or 40 for fine adjustment of the level and direction, and the length and diameter of the column are determined by the geology and load.

  The doubling plate 30 or 40 is installed on the flange 4 provided at the upper end of the foundation column 1 and can be moved up and down and rotated freely. The column 1 is supported by the bolt 6 in FIG. 5 or the set bolt 43 in FIG. Can be fixed.

  There are various types of stand-type solar panel mounts, but they are roughly divided into two types: one that supports the stand with a pillar and one that supports the bottom of the mount as a beam. The doubling plates 30 and 40 used for the level fine adjustment suitable for these two mounts will be described below.

  FIG. 5 shows the doubling plate 30 in the case where the legs of the stand of the solar panel in the field are pillars. The doubling plate 30 is a circle having the same size as the flange 4 of the column 1, and the doubling plate 30 and the flange 4 Several liner plates 31 are sandwiched between them, and are fastened with four bolts 6 through the peripheral holes 5 to finely adjust the level.

  On this doubling plate 30, the pillars of the solar panel pedestal legs are installed with set bolts 33.

  FIG. 6 shows a doubling plate 40 when the bottom of a stand-up solar panel mount is supported by a beam. In this case, the beam is placed in the lateral direction, and therefore the shape of the doubling plate 40 is preferably rectangular.

  The doubling plate 40 on which the beam is installed has a rectangular shape having two mounting holes 41 on the upper surface, and an inner tube 42 that is inscribed in the column tube 1 is provided below the rectangular plate 40.

  This inner tube 42 is inserted into the column tube 1 and can be freely slid up and down and rotated, and after fine adjustment of a predetermined level and direction, the inner tube 42 is fixed with a set bolt 43 and is set on the doubling plate 40. Install the solar panel mount beam.

  The installation of the solar panel is completed by installing the solar panel on the doubling plate 30 or 40 provided on the top of the support columns 1 as many as necessary to meet the total weight of the solar panel and the base and the geological condition of the ground.

  At the time when the nostalgic solar panel is no longer needed, the pillar 4 can be pulled out by reversely rotating the hydraulic motor 11 on the flange 4 of the foundation pillar 1 and no backfilling is required.

  The extracted strut 1 can be recycled and reused.

  The foundation strut of the present invention can be used and applied to the foundation of ground structures such as solar panel mounts, temporary buildings, prefabs, signboards, carports, temporary tents, fences, poles, benches and the like.
