Description

  The present invention relates to a fixing base for fixing a structure such as a solar power generation unit or a solar water heater via an anchor embedded on a slab.

  Conventionally, when installing, for example, a photovoltaic power generation unit as a structure on a slab such as on a flat roof, an anchor bolt or the like for fixing the photovoltaic power generation system is installed in the mold while assembling a mold on the flat roof. After that, concrete was placed in the formwork and the concrete was sufficiently dried, and then a solar power generation system was installed. For this reason, it took time to install the photovoltaic power generation system, and there was a problem that costs increased.

  On the other hand, a proposal was made to place block-shaped foundations made of concrete or the like on the slab in advance at predetermined intervals, and to fix the foundation of the photovoltaic power generation unit to the foundation. (For example, Patent Document 1). Alternatively, after fixing the lower surface of the anchor member from which the bolt protrudes from the plate-like base portion to the plate fixed on the slab, the fixing member is attached to the bolt of the anchor member, and sunlight is applied to the fixing member. A device in which the frame of the power generation unit is fixed has also been proposed (for example, Patent Document 2).

  However, in the thing of patent document 1, since the block-shaped foundation for installing a photovoltaic power generation unit is only mounted on the slab, it cannot obtain sufficient installation strength with respect to a typhoon or an earthquake. There's a problem. Therefore, it is conceivable to fix the block-shaped foundation to the slab. However, since the block-shaped foundation is not provided with holes or the like for fixing to the slab, there is a problem that it takes time and effort to fix. Moreover, since the block-shaped foundation like the thing of the patent document 1 is generally formed in solid with concrete, there exists a problem that a heavy carrying work and installation work become heavy and construction cost increases.

  On the other hand, since the anchor member is bonded and fixed to the plate fixed to the slab in the cited document 2, the anchor member is easily detached from the plate when the adhesive deteriorates due to secular change, and sunlight is applied to the slab. There is a problem that the power generation unit cannot be fixed sufficiently.

  In view of the above circumstances, an object of the present invention is to provide a fixing base that can easily and firmly fix a structure such as a photovoltaic power generation unit on a slab.

In order to solve the above-described problems, the fixing base according to the present invention includes a plate-like base portion placed on the surface of the slab and an anchor bolt formed in the center of the base portion and embedded in the slab. An anchor fixing portion for fixing to the anchor nut, a main body portion that rises in a cylindrical shape from the upper surface of the base portion around the anchor fixing portion, and an end portion of the main body portion opposite to the base portion And a structure fixing portion that is formed on the top surface of the top portion and coaxially with the anchor fixing portion, and fixes the structure. The anchor fixing portion is embedded in the slab. An anchor bolt or a male screw portion of a bolt screwed to an anchor nut is a through-hole penetrating the base portion, and the main body portion is an anchor that has passed through the through-hole. N screwed into the bolt DOO, or from said upper passed through a through-hole is screwed into the anchor nut bolt, is can pass through, and includes a side surface of the opening of the tool can be inserted magnitude to rotate the nut or bolt It is characterized by that.

  Here, “slab” is a plate-like structure made of concrete, “what constitutes the roof of a building”, “what constitutes the roadbed”, “what constitutes the top of the building” And the like.

  Examples of the “main body” include “cylindrical ones”, “polygonal ones (square, hexagonal, etc.)”, “conical ones whose upper side is constricted”, etc. can do. In addition, the “top part” is formed so as to be larger than the area of the upper end of the main body part (the end part opposite to the base part) that is “formed so as to close the cylinder of the main body part”. Things ", etc. can be illustrated.

  Furthermore, examples of “structures” include “solar power generation unit”, “solar water heater”, “air conditioner outdoor unit”, “greening unit”, “soundproof panel unit”, “light shielding panel unit”, etc. can do. Examples of the “structure fixing portion” include “a male screw member protruding upward”, “a female screw hole penetrating the top portion”, “a through hole penetrating the top portion”, and the like.

  According to the present invention, as in the prior art, a formwork is assembled on a slab such as a flat roof and an anchor is installed, and concrete is placed in the formwork to fix a structure such as a photovoltaic power generation system. Compared to the case where a base is formed, an anchor is embedded in the slab (for example, an adhesive anchor is embedded), and then the anchor fixing portion formed at the center of the base portion of the fixing base is attached to the slab. It is possible to easily fix the structure on the slab by fixing it to the anchor (bolt or nut) embedded and fixing the structure such as the photovoltaic power generation unit to the structure fixing part formed on the top. In addition, the workability related to the installation of the structure can be improved and the construction period can be greatly shortened, and the cost related to the installation of the structure can be reduced.

  In addition, since the main body is formed in a cylindrical shape, the weight of the fixed base can be reduced compared to the conventional one made of solid concrete, and handling is improved and transport work It is possible to improve the workability by facilitating installation work and the like. In addition, since the main body is formed in a cylindrical shape, even if the direction of the force acting on the fixed base from the structure side changes in various directions (for example, wind direction, earthquake shaking direction, etc.) The same fixing strength can be exhibited with respect to the direction, and the structure can be firmly installed and fixed.

  Furthermore, since the anchor fixing portion for fixing to the anchor embedded in the slab and the structure fixing portion for fixing the structure are coaxially arranged, the load applied from the structure side is directly attached to the anchor. Can be transmitted to the slab, and the fixing strength of the structure can be increased as much as possible.

  In addition, when the upper end of the cylindrical main body is closed at the top, rainwater or the like can be prevented from entering the main body, and the interior of the main body is corroded by water and durability is reduced. In addition, it is possible to prevent water from entering the slab from the inside of the main body through the anchor fixing portion, and to prevent problems on the slab side.

  Further, it is desirable to integrally form the base portion of the fixing base, the anchor fixing portion, the main body portion, the top portion, and the structure fixing portion (at least, the base portion, the main body portion, and the top portion are integrally formed) Thereby, compared with what was assembled using the adhesive like the thing of patent document 2, the fall of the intensity | strength by a secular change can be suppressed, and the durability and the reliability with respect to installation and fixing of a structure Can increase the sex.

  Furthermore, the fixing base may be directly fixed on the concrete surface of the slab, or may be fixed on the upper side of a waterproof layer (for example, a waterproof sheet, a waterproof resin coating, etc.) formed on the upper surface of the slab.

  Here, “tools” include “wrench (also called spanner)”, “glass wrench”, “ratchet wrench”, “monkey wrench”, “hexagon wrench”, “socket wrench”, “torque wrench”, “electric” Examples include “wrench”, “impact wrench”, and the like. Further, the “size that allows the tool to be inserted” is preferably a size that allows the tool to be rotated by 45 to 135 degrees or 60 to 120 degrees with respect to the circumferential direction of the main body. If it is smaller than this range, the workability of tightening the nuts and bolts is deteriorated, and if it is larger than this range, the strength of the main body part is lowered and the structure may not be sufficiently supported. It is.

  By the way, when the anchor fixing portion is a female screw hole screwed into an anchor bolt embedded in the slab or a male screw member that can be screwed into an anchor nut embedded in the slab, When the fixing base is fixed, the fixing base must be rotated in order to fasten and fix to the anchor bolt or the anchor nut. In addition, since the orientation of the fixing base when it is fastened to the slab varies, especially when the main body has a directionality in the rotational direction such as a polygonal cylinder, the fixing base fastened to the slab is fixed. If the orientation is different, there is a problem that it looks bad.

  On the other hand, according to the present invention, the anchor fixing portion is a through hole that is not screwed with an anchor bolt or the like, and the fixing base is fastened by screwing the nut or bolt to the anchor bolt or the anchor nut from above through the through hole. Since it is made to fix, it is not necessary to rotate a fixed base at the time of fastening, a fixed base can be fixed toward arbitrary directions, and a fixed base can be fixed with good appearance to a slab.

  Moreover, since a tool can be inserted from the opening part of a main-body part, a nut and a volt | bolt can be rotated with the inserted tool, and a fixed base can be reliably fixed to a slab. In addition, since the anchor fixing portion is a through hole, the lower surface of the base portion can be a flat surface, and the fixing base can be made stable during storage or the like.

  In addition, it is desirable that the anchor fixing portion on the upper surface of the base portion is higher than other portions, so that rainwater or the like that has entered from the opening of the main body enters the slab side through the through hole. The possibility can be reduced, and the waterproof performance can be enhanced to prevent the occurrence of a problem on the lower surface of the base portion or the slab side.

  Further, the fixing base according to the present invention is, in addition to the above-described configuration, “the base portion is inclined so that an upper surface located inside the main body portion is lowered toward the opening portion”. It is good as a feature.

  According to the present invention, since the upper surface in the main body portion of the base portion is inclined so as to become lower toward the opening portion, even if rainwater or the like enters the main body portion from the opening portion, the inclined upper surface immediately It can be discharged out of the main body, and it can be prevented that water accumulates in the main body and the fixing base is corroded or the water is spoiled and a strange odor is generated.

  Further, the fixing base according to the present invention is as follows: “The base portion is placed on the surface of the slab via an adhesive, and air between the slab is discharged to a position outside the main body portion. It is good also as a feature that it has a plurality of punching holes.

  By the way, in order to further increase the fixing strength of the fixing base with respect to the slab, it is conceivable that an adhesive is interposed between the slab and the base portion of the fixing base. If air is trapped, there is a problem that the bonding area decreases and the bonding strength decreases. For this reason, in order to prevent air from being caught between the slab and the base portion, it is necessary for the operator to pay close attention when bonding the base portion, which causes a troublesome problem.

  On the other hand, according to the present invention, since the base portion is provided with a plurality of holes, for example, the base portion (fixed base) is pressed onto the slab in a state where an adhesive is attached to the lower surface of the base portion. As a result, the adhesive spreads sideways, and the air sandwiched between them can be discharged from the punched hole together with the excess adhesive, and the base is firmly bonded to the entire surface of the base to secure the slab. Fixing strength can be increased.

  In addition, since excess adhesive is discharged from the punched hole along with air to the upper surface side of the base portion, if the adhesive is cured in that state, the mechanical adhesive strength by the adhesive can be further increased. The fixing base can be fixed more firmly. Furthermore, since the base part of the fixing base is bonded to the slab via an adhesive, the waterproof performance on the lower side of the fixing base can be improved by this adhesive, and water can enter the slab. It is possible to prevent problems from occurring.

  In addition, screws or the like may be screwed or driven into the slab from the upper side of the base through a plurality of punched holes, and the fixing strength of the fixing base to the slab can be further increased, and the structure is strong against the slab. Can be installed. Moreover, it is desirable to use an adhesive having excellent water resistance and weather resistance, and a known adhesive can be used.

  Thus, according to the present invention, it is possible to provide a fixing base capable of easily and firmly fixing a structure such as a photovoltaic power generation unit onto a slab.

It is a perspective view which shows the fixing stand of the form further different from the example of FIG. It is a perspective view which shows the fixing stand of the form further different from the example of FIG.

  A fixing base according to an embodiment of the present invention will be described in detail with reference to FIGS. FIG. 1 is a perspective view showing a single stand of a fixing base according to an embodiment of the present invention. 2 is a side view schematically showing a state where the photovoltaic power generation unit is installed on the slab using the fixing base of FIG. 1, and FIG. 3 is a cross-sectional view showing an enlarged main part of FIG. It is. As shown in FIG. 2 and the like, the fixing base 1 of this embodiment is for installing and fixing a photovoltaic power generation unit 20 as a structure on a slab 10 such as a flat roof.

  As shown in FIGS. 1 and 3, the fixing base 1 of the present embodiment is formed in a plate-like base portion 2 placed on the surface of the slab 10 and the center of the base portion 2 and embedded in the slab 10. An anchor fixing portion 3 for fixing to the anchor bolt 11, a main body portion 4 that rises in a cylindrical shape from the upper surface of the base portion 2 around the anchor fixing portion 3, and an end opposite to the base portion 2 in the main body portion 4 A top portion 5 that closes the top portion (upper end portion), and a structure fixing portion 6 that is formed at a position coaxial with the anchor fixing portion 3 on the top surface of the top portion 5 and fixes the photovoltaic power generation unit 20. ing.

  In addition, the fixing base 1 has an opening having a size that allows a nut 12 to be screwed to the anchor bolt 11 to pass through the outer peripheral surface of the main body 2 and insert a tool such as a wrench that rotates the nut 113. 7 is provided. Further, the fixed base 1 includes a plurality of punched holes 8 penetrating in the vertical direction at positions outside the main body portion 4 in the base portion 2.

  The base portion 2 of the fixed base 1 of this example has a rectangular outer shape, and an upper surface located inside the main body portion 4 is inclined so as to become lower toward the opening portion 7. Intruded rainwater or the like can be discharged from the opening 7 to the outside. The anchor fixing portion 3 is a through hole through which the anchor bolt 11 can pass, and is formed so that the upper surface is higher than the upper surface of the base portion 2, and rainwater or the like is formed on the upper surface of the base portion 2. It is possible to make it difficult to enter the anchor fixing portion 3 (through hole) even if it is immersed.

  The main body 4 is formed in a cylindrical shape that is substantially concentric with the axis of the anchor fixing portion 3, and has an opening 7 that is notched in the circumferential direction from the lower end. In this example, the size of the opening 7 is in the range of about 120 degrees with respect to the center of the cylinder of the main body 4 in the circumferential direction, and is formed to have a height of about 100 mm from the lower end. The nut 12 and the washer and packing to be screwed onto the anchor bolt 11 can be inserted from the outside, and the nut 12 can be sufficiently rotated by inserting a tool such as a ratchet wrench.

  Furthermore, the structure fixing | fixed part 6 is made into the external thread part extended predetermined length upwards in this example so that it may show in figure. Further, eight punch holes 8 are formed on the outer side of the main body portion 4 in the base portion 2 at intervals of 45 degrees around the axis of the main body portion 4.

Further, in the fixing base 1 of this example, the base portion 2, the anchor fixing portion 3, the main body portion 4, the top portion 5, and the structure fixing portion 6 are integrally formed of aluminum alloy, cast iron, synthetic resin, fiber reinforced resin, or the like. Has been. In the case where resin is used for the fixing base 1, at least the anchor fixing portion 3 and the structure fixing portion 6 are formed of metal and integrally formed with the main body portion 4 or the like by an insert or the like. Moreover, as resin used for the fixing stand 1, it is desirable to use resin excellent in weather resistance. Furthermore, a coating such as plating or painting may be applied to the surface of the fixing base 1 in order to enhance the corrosion resistance, the design, and the like. Incidentally, the size of the fixing base 1 of this example is such that one side of the base portion 2 having a substantially square shape in plan view is about 200 mm, the diameter of the cylindrical main body portion 4 is about 120 mm, and the height of the main body portion 4 is about 150 mm. Has been.

  Next, the installation method (construction method) of the structure using the fixed base 1 of this embodiment is demonstrated. Here, the example at the time of using for the solar power generation unit 20 as a structure is demonstrated. First, anchor bolts 11 are embedded at predetermined intervals on a slab 10 such as a flat roof on which the solar power generation unit 20 is installed by a known method. As an interval for embedding the anchor bolts 11, an interval corresponding to the arrangement pitch of the plurality of solar cell modules 21 in the photovoltaic power generation unit 20 is desirable. In this example, the interval is substantially the same as the arrangement pitch of the solar cell modules 21. Interval. The anchor bolt 11 may be embedded at the same time as the slab 10 is formed.

  When the anchor bolt 11 is embedded in the slab 10, a predetermined adhesive 13 (adhesive resin) is applied to the entire lower surface of the fixing base 1, the fixing base 1 is positioned above the anchor bolt 11, and the anchor bolt 11 Is placed on the slab 10 so that passes through the anchor fixing portion 3 (through hole). Then, when the fixing base 1 is placed on the slab 10, the fixing base 1 is pressed from above to the slab 10 side, and the adhesive 13 protrudes from the outer edge of the base portion 2 and the punch hole 8. Thereby, the air pinched | interposed between the base part 2 and the slab 10 can be discharged | emitted from the outer edge of the base part 2, and the extraction hole 8, and it adheres to the slab 10 on the whole surface of the base part 2 reliably. be able to. The protruding adhesive 13 is removed with a spatula or the like.

  Subsequently, the screw 14 is screwed into the slab 10 from the upper side of the base portion 2 through the punch hole 8. Moreover, after inserting packing, a washer, etc. from the upper side to the anchor bolt 11 which protruded in the main-body part 4 through the opening part 7, the nut 12 is screwed together and the nut 12 is tightened using tools, such as a ratchet wrench. In addition, it is desirable to tighten the nut 12 using a torque wrench as a tool. By fastening with the proper torque, the best fixing strength can be obtained and the nut 12 can be prevented from loosening.

  When the plurality of fixing bases 1 are fixed to the slab 10 in this way, the long support rail 22 is fixed to the structure fixing portion 6 of the fixing base 1 so as to straddle the plurality of fixing bases 1. Specifically, after the structure fixing portion 6 is inserted into the fixing hole 22a formed in the lower surface of the support rail 22, the nut 23 is screwed into the structure fixing portion 6 with a washer and a spring washer from above. The support rail 22 is fixed to the upper surface of the fixing base 1. Thereafter, by attaching the solar cell module 21 to the upper surface of the support rail 22 via a predetermined mounting bracket 24, the photovoltaic power generation unit 20 can be installed on the slab 10, as shown in FIG.

  In addition, although detailed illustration is omitted, in the photovoltaic power generation unit 20 of this example, a long module support rail extending in a direction perpendicular to the paper surface of FIG. The solar cell module 21 is attached to the module support rail. Moreover, the structure of the solar power generation unit 20 mentioned above is an example, and as a structure which supports the solar cell module 21, the thing of another structure may be employ | adopted. Further, in the above description, the fixed base 1 is directly mounted on the slab 10. However, the fixed base 1 may be mounted and fixed on the slab 10 having a waterproof layer on the upper surface.

The workability related to the installation can be improved and the construction period can be greatly shortened, and the cost related to the installation of the structure can be reduced.

  Moreover, since the main-body part 4 is formed in the cylinder shape, compared with the conventional thing formed with solid concrete, the weight of the fixing stand 1 can be reduced in weight, and handling becomes good. It is possible to improve the workability by facilitating carrying work and installation work. Further, since the main body 4 is formed in a cylindrical shape, the direction of the force acting on the fixed base 1 from the photovoltaic power generation unit 20 side (structure side) changes in various directions (for example, wind direction, earthquake vibration). Direction, etc.), the same fixing strength can be exhibited in any direction, and the photovoltaic power generation unit 20 can be firmly installed and fixed.

  Furthermore, since the anchor fixing portion 3 for fixing to the anchor bolt 11 embedded in the slab 10 and the structure fixing portion 6 for fixing the solar power generation unit 20 are arranged on the same axis, the solar power generation unit The load applied from the 20 side can be transmitted almost directly to the slab 10 via the anchor bolt 11, and the fixing strength of the photovoltaic power generation unit 20 can be increased as much as possible.

  In addition, since the base portion 2, the anchor fixing portion 3, the main body portion 4, the top portion 5 and the structure fixing portion 6 of the fixing base 1 are integrally formed, a plurality of parts can be bonded (welded) or assembled. Compared with what was done, the fall of the intensity | strength by a secular change can be suppressed, durability can be improved and the reliability with respect to installation and fixation of the photovoltaic power generation unit 20 can be improved.

  Further, the anchor fixing portion 3 is a through hole that is not screwed with the anchor bolt 11 and the nut 12 is screwed from above through the through hole so that the fixing base 1 is fastened and fixed. There is no need to rotate the table 1, and the fixed table 1 can be fixed in an arbitrary direction, and the fixed table 1 can be fixed with good appearance to the slab 10.

  Moreover, since a tool can be inserted from the opening part 7 of the main-body part 1, the nut 12 can be rotated with the inserted tool, and the fixed base 1 can be fixed to the slab 10 reliably. Further, since the anchor fixing portion 3 is a through hole, the lower surface of the base portion 4 can be a flat surface, and the fixing base 1 can be in a stable state during storage or the like.

  Furthermore, since the upper surface in the main body portion 4 of the base portion 2 is inclined so as to become lower toward the opening portion 7, even if rainwater or the like enters the main body portion 4 from the opening portion 7, the inclined upper surface It can be immediately discharged from the opening 7 to the outside of the main body 4, and the water can be accumulated in the main body 4 to prevent the fixing base 1 from being corroded or water from being spoiled to generate a strange odor. Can do.

  In addition, since the base portion 2 is provided with a plurality of holes 8, by pressing the base portion 2 (fixing base 1) onto the slab 10 with the adhesive 13 attached to the lower surface of the base portion 2, As the adhesive 13 spreads laterally, the air sandwiched between it can be discharged from the punch hole 8 together with the extra adhesive 13, and it is securely bonded to the entire surface of the base portion 2 and fixed to the slab 10. The fixing strength of the table 1 can be increased.

  Furthermore, since the base portion 2 of the fixing base 1 is bonded to the slab 10 via the adhesive 13, the waterproof performance on the lower side of the fixing base 1 can be improved by this adhesive 13, and the slab It is possible to prevent a problem from occurring due to water entering 10 or the like. Further, since the screws 14 are screwed into the slab 10 from the upper side of the base portion 2 through the plurality of punched holes 8, the fixing strength of the fixing base 1 with respect to the slab 10 can be further increased, and solar power generation is performed on the slab 10. The unit 20 can be firmly installed.
