Description

  The present invention relates to a column fixing method in which a plurality of columns are erected and fixed at a column arrangement planned position on an installation surface, and a fixture used therefor.

  In recent years, so-called mega solar installations have been performed in which a large number of solar cell panels are installed on fallow farmland or the like to generate power.

  In general, as a facility for installing the solar cell panel, an assembly-type gantry including two or more legs for supporting the solar cell panel is known. The gantry is formed such that a bottom surface facing the installation surface is horizontally formed, and an upper end on which the solar cell panel is placed is formed at a predetermined inclination angle capable of efficiently performing solar power generation.

  Conventionally, as a method of fixing the gantry to the installation surface using a fixture, assembling the gantry after attaching the leg holding portion of the fixture to the leg of the gantry before assembly, and burying the leg in the installation surface, Thereafter, a method is known in which the driven pile is inserted into the pile holding portion of the fixture and driven into the ground (for example, see Patent Document 1).

JP 2013-227767 A

  The method described in Patent Document 1 uses a pedestal with high dimensional accuracy when embeding a leg portion of the gantry, and determines the position where the leg portion is embedded while assembling the gantry at the work site. Accurate dimensioning of the part can be easily performed.

  On the other hand, when a solar cell panel is installed on an inclined ground such as a forest, an inclined mount may be unnecessary, and in such a case, the above method cannot be used.

  Normally, when installing some equipment on the slope, it is necessary to install the equipment after leveling the slope. However, if the slope of the slope exceeds a predetermined value (for example, 20 °), a heavy machine is put on the work site. It is impossible to perform leveling work using heavy machinery. Even when a concrete foundation is placed, if the inclination angle is large, the concrete mixer truck may not be able to enter, and the operation is not easy.

  The present invention is a method of fixing a column that can be easily set up and can be quickly operated even when a column on which an installation object such as a solar battery panel is placed is set up on an inclined ground. The purpose is to provide.

  In order to achieve the above object, the first invention is a column fixing method in which a plurality of columns are erected at a column arrangement planned position on the installation surface, and the column is fixed using a fixture, and the fixture includes: A cylindrical column holding part that is rotatable with respect to the column when mounted on the column, and a pile holding unit that holds a driving pile that is connected to the column holding unit and is driven into the ground, A step of standing a column at a planned column arrangement position of the installation surface, a step of burying the lower part of each column in the ground so as to form a virtual surface by connecting at least one upper end of each column, For each of the pillars, the pillar holding part of the fixture is mounted from the upper end side of the pillar, and the pile holding part is directed in a desired direction by rotating the fixture around the pillar. And fixing the fixtures arranged for each column to the column after performing the step of arranging in a state, It is passed through the ball striking inclusive pile 該杭 holder the fastener driving into the ground for beauty each strut and performing in any order the steps of fixing with respect to the installation surface.

  In the support fixing method of the first invention, a fixing tool for fixing the support is used. The fixture includes a cylindrical column holding portion that is rotatable with respect to the column when mounted on the column, and a pile holding unit that holds a driving pile that is connected to the column holding unit and is driven into the ground. It has.

  In the column fixing method of the first invention, first, each column is erected at a column arrangement planned position on the installation surface. At that time, it is possible to determine the column arrangement planned position by performing ink marking which is normally performed in this type of construction method.

  Next, the lower part of each support | pillar is embed | buried in the ground so that at least 1 point of the upper end of each support | pillar may be tied and a virtual surface may be formed. This virtual surface is a surface on which the bottom surface of the installation object (the back surface in the case of a solar cell panel) is placed. The step of forming the virtual surface is performed by adjusting the height of the upper end of each column using the level of the surveying instrument or the like.

  At this time, even if the installation surface is not limited to a flat ground, even if it is a sloped land or has a concavo-convex part, by adjusting the embedding depth of the pillars in the ground, at least on the top surface of each pillar A virtual plane can be formed by connecting one point. The virtual surface may be horizontal or may be inclined at an arbitrary angle with respect to a horizontal plane. In addition, the virtual surface is not necessarily a flat surface, and may have a step or a curved surface.

  Next, for each embedded support column, the support member holding part of the fixture is mounted from the upper end side of the support column, and the fixing tool is rotated around the support column so that the pile holding unit is set in a desired manner. Arrange it in the direction.

  The step of rotating the fixing tool may be performed before fixing the column holding part and the column or before inserting the driving pile into the pile holding unit and driving it into the ground. In addition, this step includes a case where the angle is determined in advance before the fixing tool is attached to the support, that is, a case where the fixing tool is attached to the support after the fixing tool is rotated with respect to the support.

  Next, a step of fixing the fixing tool arranged for each column to the column is performed, and then the driving pile is inserted into the pile holding portion for each column, and the fixing tool is fixed to the installation surface in the ground. Perform the process. Alternatively, for each strut, the step of inserting the driving pile into the pile holding portion and fixing the fixing tool to the installation surface is performed in the ground, and then the step of fixing the fixing tool arranged for each strut to the support column is performed. . These two steps can be performed in any order depending on the situation at the work site.

  According to the support fixing method of the first aspect of the present invention, a virtual surface can be formed by the upper end of each support only by driving each support erected at the support placement planned position on the installation surface into the ground by a desired amount. Moreover, each column may be fixed by driving a driving pile into the fixture and fixing the column holding part and column. Therefore, there is no need for leveling of the installation surface when fixing each column, so no heavy machinery or the like is required.

  Therefore, according to the column fixing method of the first invention, a plurality of columns can be erected and fixed on the installation surface easily and quickly not only on a flat ground but also on a steeply inclined land.

  In order to achieve the above object, the second invention is a column fixing method in which a plurality of columns are erected at a column arrangement planned position on the installation surface, and the column is fixed using a fixture, the fixture Comprises a cylindrical column holding part that is rotatable with respect to the column when mounted on the column, and a pile holding unit that holds a driving pile that is connected to the column holding unit and is driven into the ground. A step of arranging the support column holding portion of each fixture at a planned column arrangement position on the installation surface, and inserting each column into each column holding unit from the lower end side, and standing the column at the planned column arrangement position. A step of embedding the lower part of each column in the ground so that a virtual plane is formed by connecting at least one point on the top surface of each column, and for each column, the fixing device is centered on the column. A hollow cylindrical pile that is provided on the outer peripheral surface of the support holder to hold the driven pile And a step of arranging the holding portion in a state in which the holding portion is directed in a desired direction, and a step of fixing the fixing device arranged for each column to the column, and the driving pile for each column to the pile holding unit The step of inserting and driving into the ground to fix the fixture to the installation surface is performed in any order.

  Also in the column fixing method of the second invention, the same fixing tool as that of the first invention is used. In the column fixing method according to the second aspect of the invention, the column holding part of each fixture is first arranged at the column arrangement planned position on the installation surface. Next, each column is inserted into each column holding part from the lower end side, and each column is erected at a column arrangement planned position.

  Next, the lower part of each support | pillar is embed | buried in the ground so that a virtual surface may be formed by connecting at least one point on the top surface of each support | pillar. At this time, it is possible to form a virtual surface by connecting at least one point on the top surface of each column by adjusting the depth of the column to be buried in the ground. It becomes the surface to be placed.

  Next, for each strut, the hollow cylindrical pile holding portion that is provided on the outer peripheral surface of the strut holding portion and holds the driven pile is turned in a desired direction by rotating the fixture around the strut Place with.

  Next, a step of fixing the fixing tool arranged for each column to the column is performed, and then the driving pile is inserted into the pile holding portion for each column, and the fixing tool is fixed to the installation surface in the ground. Perform the process. Alternatively, the driving pile is inserted into the pile holding portion for each column, and the step of driving in the ground and fixing the fixture to the installation surface is performed, and then the step of fixing the fixture arranged for each column to the column is performed. These two steps can be performed in any order depending on the situation at the work site.

  According to the column fixing method of the second invention, first, the column holding part of the fixture is arranged at the column arrangement planned position on the installation surface, so that the fixture can be used as a mark when standing the column. Becomes easy. Similarly to the first invention, a virtual plane formed by the upper ends of the columns can be formed by simply driving each column erected at the column arrangement planned position on the installation surface into the ground by a desired amount. Moreover, each column may be fixed by driving a driving pile into the fixture and fixing the column holding part and column. Therefore, there is no need to level the installation surface, so no heavy machinery is required.

  Therefore, according to the column fixing method of the second invention, it is possible to easily and quickly stand and fix a plurality of columns on the installation surface not only on a flat ground but also on a steep slope.

  In the plurality of support columns erected by the support fixing method of the first or second invention, one virtual plane is formed by the upper ends of the support columns, and therefore the inclination angle of the virtual plane with respect to the horizontal plane is set to a predetermined inclination. Setting the angle is suitable for placing a solar cell panel as an installation on the virtual plane.

  Further, the column fixing method of the first invention or the second invention is a fixture for fixing a column that is erected at a column arrangement planned position on the installation surface, and is attached to the column when mounted on the column. And a cylindrical column support portion that is rotatable, and a pile holding portion that holds a driving pile that is connected to the column support portion and is driven into the ground, and the column support portion has an inner circumference having a circular cross section A fixing tool including a surface and having the pile holding portion fixed to the outer peripheral surface of the column holding portion can be suitably used.

  According to the fixture of the present invention, since the support holder can be moved in the axial direction of the support when mounted on the support, the support can be fixed at an arbitrary position in the axial direction of the support.

  Further, according to the fixture, since the support holder has an inner peripheral surface having a circular cross section, the support holder can be rotated around the support when mounted on the support, The pile holding part can be directed in a desired direction. As a result, even if there are obstacles such as stones that obstruct the driving of the driving pile in the ground, the driving pile can be driven into the ground avoiding the obstacle and fixed to the installation surface The tool can be securely fixed.

  Moreover, since the pile holding | maintenance part is being fixed to the outer peripheral surface of a support | pillar holding | maintenance part and the distance of a support | pillar holding | maintenance part and a pile holding | maintenance part is near, a driving pile can be driven in the vicinity of a support | pillar.

  If there is a distance between the column holding part and the pile holding part, when fixing the column to an inclined ground, the pile holding part must be placed above the column holding part. Is far from the surface.

  In particular, when the pile holding part is provided at least in two places across the column holding part, the distance between the pile holding part on the side away from the ground surface and the ground surface may be separated, and the driven pile may not be effective. is there.

  However, when the distance between the column holding part and the pile holding part is short, the distance between the pile holding part on the side away from the ground surface and the ground surface is also close, so that the driving pile can be driven effectively.

Further, the driven pile S similarly uses a stainless steel cylindrical tube, but any material and shape can be used.

  The fixing tool 1 is fixed to a hollow cylindrical column holding unit 2 that holds the column P to be inserted, and an outer peripheral surface of the column holding unit 2, and has a predetermined angle of 20 to 60 ° with respect to the axial direction of the column holding unit 2. And a plurality of pile holding portions 3 into which the driven piles S are inserted. The angle of this pile holding part 3 can be set arbitrarily.

  The support holder 2 is formed so as to have a gap between the inner peripheral surface thereof and the outer peripheral surface of the support post P to be inserted. It can move in the axial direction of the column P and can rotate around the column P.

  A column holding portion bolt hole 4 is provided in the axial intermediate portion of the column holding portion 2, and a fixing tool 1 and the column P can be fixed by screwing a bolt (not shown) into the column holding portion bolt hole 4. it can.

  The pile holding unit 3 is disposed on the outer peripheral surface of the column holding unit 2 so as to be symmetric with respect to the central axis in the axial direction of the column holding unit 2. In this embodiment, the pile holding unit 3 is located diagonally across the column holding unit 2. There are two places. A pile holding portion bolt hole 5 is provided in an axial intermediate portion of the pile holding portion 3, and a fixing tool 1 and the driving pile S can be fixed by screwing a bolt (not shown) into the pile holding portion bolt hole 5. it can.

  In the present embodiment, the pile holding portions 3 are provided at two locations across the support column holding portion 2, but may be provided at three locations every 120 ° around the support column holding portion 2. You may provide four places for every 90 degrees around.

  The pile holding portion 3 plays a role of guiding the driven pile S so as to be inclined at the predetermined angle when driven into the ground, and can prevent interference between adjacent driven piles S. .

  In the present embodiment, the fixture 1 is formed by casting the support holder 2 and the pile holder 3 together. On the other hand, the support | pillar holding | maintenance part 2 and the pile holding | maintenance part 3 can also be formed by welding etc. using a stainless steel or an iron pipe.

  Next, the column fixing method of the first embodiment will be described with reference to FIGS. 3 and 4. Here, the case where solar cell panel SP supported by the support | pillar P is installed in slopes, such as a forest, is demonstrated. Since the slope of the slope is approximately 20 ° and is suitable for the slope of the solar cell panel SP, in the present embodiment, the solar cell panel SP is installed substantially parallel to the slope.

  First, surveying is performed at the installation location of the solar cell panel SP, and marking is performed, thereby marking the planned column arrangement position X on the installation surface G. Further, as shown in FIG. 3A, in order to clarify the height of the upper end Pb of the support P from the ground surface, the thread L is stretched in accordance with the installation angle θ of the solar cell panel SP (FIG. 4). ST1).

  Next, as shown in FIG. 3A, the column P is erected by driving it into the ground with a hammer or the like (ST2).

  The amount of striking the lower part Pa of the strut P into the ground is adjusted for each strut so that the upper end Pb of the strut P becomes the height of the thread L (ST3). The operations of ST2 and ST3 are repeated, and the number of columns P required for the installation of the solar cell panel SP are driven into the column arrangement planned positions. Through a series of these operations, the upper ends Pb of the plurality of columns P are buried at a height that forms a virtual surface for installing the solar cell panel SP.

  Next, as shown in FIG.3 (b), about each support | pillar P, the support | pillar holding part 2 of the fixing tool 1 is mounted | worn from the upper end Pb side. And the fixing tool 1 is moved toward the downward direction of the support | pillar P, and is arrange | positioned on the installation surface G (ST4).

  Next, when there is a stone R or the like that will obstruct the driving of the driving pile S in the ground, the obstacle 1 is avoided by rotating the fixing tool 1 around the column P. The direction of the pile holding part 3 is adjusted (ST5).

  Next, the fixing tool 1 mounted on each column P is screwed with a bolt (not shown) into the column holding part bolt hole 4 to fix the fixing unit 1 and the column P (ST6). At this time, if the driving tool S cannot be driven unless the fixing tool 1 is shifted above the support P, the fixing tool 1 can be fixed to the support P by being slightly separated from the installation surface G.

  Next, as shown in FIG.3 (c), about each support | pillar P, the driving pile S is penetrated to the pile holding | maintenance part 3 of the fixing tool 1, and it plunges into the ground, Furthermore, if necessary, the bolt for pile holding | maintenance parts The fixing tool 1 is fixed to the installation surface G by screwing a bolt (not shown) into the hole 5 to fix the fixing tool 1 and the driving pile S (ST7). At this time, either step ST6 or ST7 may be performed first depending on the situation of the installation location.

  Thereafter, the solar cell panel SP is installed on a virtual surface formed by the upper end Pb of the support P using a bracket or the like (not shown).

  Thus, according to the column fixing method of the first embodiment, when the plurality of columns P are erected at the column arrangement planned positions X on the installation surface G and fixed using the fixture 1, each column P is fixed. A virtual surface can be formed by the upper end Pb.

  In 1st Embodiment, the inclined surface which inclines to predetermined angle (theta) which installs said panel SP with respect to a horizontal surface can be formed as said virtual surface. And the solar cell panel SP as an installation thing can be mounted in the some support | pillar P which comprises the said virtual surface, without using the mount frame of a prior art.

  According to the support fixing method of the first embodiment, since there is no need for leveling of the installation surface G, no heavy machinery is required, and a plurality of support columns P can be easily and quickly installed not only on flat ground but also on steep slopes. G can be erected and fixed.

  Therefore, even in the case where a large amount of solar cell panels SP have to be installed as in the case of mega solar, the column fixing method according to the first embodiment can easily suppress a large amount of work while suppressing the work cost and material cost. Solar cell panel SP can be installed.

  Moreover, in this embodiment, since the placement of concrete is unnecessary, since the process of concrete is also unnecessary when removing a support | pillar, removal work becomes easy. Moreover, after removing the support | pillar, a fixing tool, and a driving pile, it is also possible to transfer these support | pillars to another installation place by reusing these members.

  Next, the support | pillar fixing method of 2nd Embodiment is demonstrated, referring FIG. A description of portions common to the column fixing method of the first embodiment is omitted.

  First, similarly to ST1 in the column fixing method of the first embodiment, the column arrangement planned position X is marked on the installation surface G, and the panel SP is installed with respect to the horizontal plane at the height at which the solar cell panel SP is installed. The yarn L is stretched so as to correspond to an inclined surface inclined at a predetermined angle θ (ST11).

  Next, the fixture 1 is placed at the planned post placement position X (ST12). At this time, the fixture 1 is arranged so that the planned column arrangement position X and the axis center of the column holder 2 of the fixture 1 coincide.

  Next, the column P is inserted into the column holding part 2 of each fixture 1 from the lower end Pc side, and each column P is erected at the column arrangement planned position X (ST13).

  Next, the upper end Pb of each column P is struck with a hammer or the like to embed the lower part Pa of the column P in the ground, thereby aligning the upper end Pb of each column P to the same height as the yarn L (ST14). Thereby, the virtual surface which connected the upper end Pb of each support | pillar P is formed.

  Next, in each strut P, by rotating the fixing tool 1 around the strut P, the direction of the pile holding portion 3 is adjusted so as to avoid obstacles such as stones that obstruct the driving of the driving pile S. (ST15).

  Next, as in ST6 in the column fixing method of the first embodiment, the fixture 1 and column P mounted on each column P are fixed (ST16).

  Next, similarly to ST7 in the column fixing method of the first embodiment, for each column P, the driving pile S is inserted into the pile holding portion 3 of the fixing tool 1 and driven into the ground, and is not illustrated if necessary. The fixing tool 1 is fixed to the installation surface G by fixing the fixing tool 1 and the driving pile S with bolts (ST7). Note that ST16 and ST7 can be performed in any order.

  According to the support | pillar fixing method of 2nd Embodiment, since the fixing tool 1 is first arrange | positioned in the support | pillar arrangement | positioning planned position X, when standing upright after that, the fixing tool 1 can be used as a mark. At this time, the driving tool S can be temporarily driven into the fixing tool 1 to position the fixing tool 1.

  Or it is also possible to use the well-known universal clamp used when fixing two single pipes instead of the fixing tool 1. The universal clamp includes a main single tube holding portion that holds one single tube, and a sub single tube holding portion that is rotatable with respect to the main single tube holding portion and holds the other single tube. The crossing angle between the single pipe held by the main single pipe holding part and the single pipe held by the sub single pipe holding part can be arbitrarily set.

  In the column fixing method of the present embodiment, when two driven piles S are used, first, two sets of universal clamps are prepared.

  Next, the column P is erected at the column arrangement planned position X on the installation surface G so that the axial direction is the vertical direction. And the upper end Pb of each support | pillar P is arrange | equalized with the same height as the thread | yarn L by hitting the upper end Pb of each support | pillar P with a hammer etc. and embedding the lower part Pa of the support | pillar P in the ground.

  Next, for each column P, the main single tube holding part of the universal clamp is mounted from the upper end Pb side, and the universal clamp is moved downward of the column P and arranged on the installation surface G. Then, the universal clamp is rotated around the column P, and each sub-single tube holding part is disposed so as to be symmetric with respect to the central axis of the column P. At this time, the auxiliary single pipe holding part is set to an angle at which the driving pile S can be driven.

  Next, after fixing the column P and the main single pipe holding part, the universal clamp is fixed to the installation surface G by driving the driving pile S into the ground by inserting each sub single pipe holding part.

  As described above, in the column fixing methods of the first and second embodiments, the column P can be fixed to the installation surface G even if a universal clamp is used instead of the fixture 1.

  In addition, although each said embodiment demonstrated the construction method in the case of standing upright in the perpendicular direction, not only this but a support | pillar may be erected at arbitrary angles.
