Description

  The present invention relates to a method of installing a reinforcing base provided for installing outdoor equipment such as a solar cell module and an advertising tower on a concrete roof including a waterproof layer with lightweight cellular concrete (ALC) or reinforced concrete (RC) as a base. About. It should be noted that the concrete roof includes the roof of the concrete structure.

  Solar cells are attracting attention from the standpoints of securing energy independent of resources and protecting the environment, and the installation of solar cell modules on the roof of buildings is rapidly spreading. Conventionally, various outdoor facilities such as advertising towers, communication devices, and air conditioners have been installed on the rooftop.

  If such outdoor equipment is installed on a concrete roof, the roof may be damaged due to a heavy load due to the weight of the outdoor equipment or wind load, so a foundation that can withstand the load without adversely affecting the roof is formed. It is done to install.

  In addition, since the concrete itself generally used for concrete roofs is not waterproof, a waterproof layer such as a waterproof sheet or paint film is provided on top, and in order to form a foundation on an existing roof, consider the waterproof layer. There must be. Therefore, considering the structure of the waterproof layer in addition to the structure of the roof, since there are a wide variety of structures, it is not easy to make a foundation that can be installed on any roof, but even for such various structures Construction methods that can be installed later have been proposed.

  For example, Japanese Patent Application Laid-Open No. 2012-92629 shows an installation support base having a sword bolt on the upper side, and after laying a waterproof sheet made of a thermoplastic resin, which is a waterproof layer, on a concrete-based casing, An example is shown in which the support frame is fixed to the housing through the waterproof sheet with a support frame fixing screw.

  Japanese Patent Application Laid-Open No. 2005-194771 discloses a solar cell module mounting structure in which a solar cell module support is constituted by a long grounding member and a support frame. According to the present invention, since the external force is dispersed by using the long grounding member, the number of fixing portions on the roof can be reduced and the waterproof performance can be easily maintained. The above-mentioned two patent documents are inventions in consideration of waterproofness, and are examples of foundations that are fixed in contact with a concrete roof in a small area, such as a support leg.

JP 2012-92629 A JP 2005-194771 A

  In the bases fixed to a concrete roof with a small area shown in Patent Document 1 and Patent Document 2 described above, there are advantages in the trouble of installation and the small number of places for waterproofing treatment, Since wind loads are concentrated, a low-strength roof may be damaged, resulting in an inapplicable building. In particular, a very large wind load acts on an inclined solar module as shown in Patent Document 2.

  In addition, outdoor equipment at a high position such as the rooftop is exposed to the wind throughout the year, so that the vibration caused by the wind is transmitted to the roof for a long time, causing damage to the waterproof layer such as breakage of the waterproof sheet and mortar. It is preferable to abut on the roof surface with a large area or a long length to disperse the load or vibration.

  One method is to install a low-priced, inexpensive, long timber pier on the concrete roof, which can be used as a foundation to distribute the load by the length of the pier, and to reinforce the roof. A foundation can be constructed. However, in order to install such a reinforcing base, it is difficult to ensure waterproofness and durability, and no good construction method is found. In the state where the waterproof sealing material is exposed around the contact portion between the support frame and the roof as shown in Patent Document 1, it cannot be said that the durability is good.

  Therefore, the present invention was devised from such a viewpoint, and in a method of installing a pier-like reinforcement base as a base of a solar cell module or outdoor equipment on a concrete roof with ALC or RC as a base, waterproofing is performed. It aims at providing the installation method with high property and durability.

  In order to achieve the above-mentioned object, the reinforcing base installation method according to claim 1 of the present invention is a long pier that is a base of a solar cell module or outdoor equipment on a concrete roof 1 with ALC or RC as a base. Installation method for installing a reinforced base, which is provided with a long timber reinforced base material 11 as a base of the reinforced base 10 and a waterproof tape at the place where the reinforced base 10 is installed on the concrete roof 1 The contact portion waterproofing process for applying 12 or applying the sealing material, and the base waterproof sheet 13 of a size capable of encapsulating the reinforcing base material 11 is laid on the position of the contact portion waterproofing process, and the reinforcement is performed thereon. Place the base material 11 and fix it to the concrete roof 1 by passing through the concrete screw 14 from above the reinforcing base material 11 and lower the reinforcing base material 11 with the base tarpaulin 13 around the reinforcing base material 11 Base waterproofing process that covers the entire circumference from the top to the top, and reinforcement The sheet metal step of covering the outdoor exposed portion of the base tarpaulin 13 of the base member 11 with a cover sheet metal 16, 17 of the thin steel sheet is placed method performed sequentially.

  Since the reinforced foundation material 11 that is the base material of the reinforced foundation 10 is made of wood, it is lightweight and has a low weight burden on the concrete roof 1 and can be easily constructed. Although the waterproofness and durability cannot be obtained with wood as it is, the reinforcing base material 11 can be reliably waterproofed by the base waterproofing process. In addition, since the waterproof tape 12 or the sealing material is sandwiched between the base waterproof sheet 13 below the reinforcing base material 11 and the concrete roof 1 in the contact portion waterproofing process, the seal portion is not exposed to the outside. Further, by performing the sheet metal process, it is possible to protect the exposed portions and seams of the base waterproof sheet 13.

  Moreover, the installation method of the reinforcement foundation which concerns on Claim 2 is the installation for installing the long pier-like reinforcement foundation used as the foundation of a solar cell module or outdoor equipment on the concrete roof 1 which used ALC or RC as the foundation. A method for providing a base waterproofing step 31 in which a reinforcing base material 31 made of long wood is used as a base material for the reinforcing base 30, and the reinforcing base material 31 is entirely covered with a base waterproof sheet 33, and reinforcement on the concrete roof 1. Applying waterproof tape 32 or applying a sealing material to the abutment surface of the reinforced foundation material 31 where the foundation is installed, or the waterproofing process of the foundation, and applying the sealing material to the abutment portion waterproof process In the installation method, the fixing process of penetrating from above and fixing to the concrete roof 1 and the sheet metal process of covering the outdoor exposed portion of the base waterproof sheet 33 of the reinforcing base material 31 with the cover sheet metal 36 of the thin steel plate are sequentially performed.

  By pre-encapsulating the reinforced foundation material 31 before installation as a foundation waterproofing process with a foundation waterproof sheet 33, it can be prepared as a member, reducing the number of members to be carried to the site and shortening the construction time it can.

  According to the first aspect of the invention, the waterproofing of the reinforcing base material 11 can be reliably performed by the base waterproofing process, and the installation portion of the reinforcing base material 11 can be waterproofed reliably by the contact part waterproofing process. Moreover, since the outdoor exposed portion of the base waterproof sheet 13 can be protected by the sheet metal process, high durability can be obtained. Moreover, since the sealing part for waterproofing is not exposed outdoors between the base waterproof sheet 13 under the reinforced base material 11 and the concrete roof 1, waterproofing that is hardly deteriorated and highly durable is obtained.

  According to the second aspect of the present invention, the reinforcing base material 31 which has been subjected to the base waterproofing process in advance is prepared, the number of members to be carried into the site can be reduced, and the construction time can be shortened. Work costs can be reduced.

  In addition, a long-wood reinforcement base material 31 as a base of the reinforcement base 30 is provided, a base waterproofing process in which the reinforcement base material 31 is entirely covered with a base waterproof sheet 33, and a reinforcement base on the concrete roof 1 is installed. The abutment part waterproofing step of applying the waterproof tape 32 or applying the sealing material to the installation contact surface of the reinforcing base material 31 that has been subjected to the base waterproofing process, and the reinforcing base material 31 from above with the concrete screw 14 It can also be realized by an installation method in which a fixing process of penetrating and fixing to the concrete roof 1 and a sheet metal process of covering the outdoor exposed portion of the base waterproof sheet 33 of the reinforcing base material 31 with the cover sheet metal 36 of a thin steel plate in order.

  Embodiments of the present invention will be described below with reference to the drawings.

  FIG. 1 to FIG. 9 show a first embodiment of the present invention, in which a plurality of elongated square-shaped reinforcing bases 10 are provided in parallel on a substantially flat concrete roof 1 (hereinafter referred to as a roof 1) with a water gradient. The frame 21 is assembled with vertical and horizontal members, and the solar module 20 is tilted and fixed on the roof 1.

  The roof 1 is a roof of an RC building, and a roof waterproof sheet 2 is installed on a concrete slab having a thickness of 100 mm corresponding to a roof base. The roof 1 including the roof waterproof sheet 2 as the waterproof layer is referred to as a roof 1. The roof tarpaulin 2 is a general rubber asphalt roofing tarpaulin that is affixed on a concrete slab with an adhesive and has a thickness of about 1 mm including the adhesive layer.

  Next, a method for installing the reinforcing base 10 on the roof 1 as described above will be described. To install the reinforced base 10, mainly the reinforced base material 11 of the long wood that is the base material of the reinforced base 10, the base waterproof sheet 13, the butyl tape 12 as the waterproof tape, the concrete screw 14, and the cover sheet metal Use base sheet metal 16,17. In the present embodiment, the reinforcing base material 11 is a wood having a square cross section of 105 mm in length and 150 mm in width and having a length of about 2180 mm.

  As shown in FIG. 6 and FIG. 7, first, a double-sided adhesive butyl tape 12 having the same size as the bottom surface of the reinforcing base material 11 is applied to the place where the reinforcing base 10 is installed on the roof 1 as a contact portion waterproofing process. . Then, a strip-shaped base waterproof sheet 13 larger than the reinforcing base material 11 in plan view is stuck on the top so that the butyl tape 12 is centered in both width and length. In this embodiment, the base tarpaulin 13 is an asphalt roofing sheet similar to the roof tarpaulin 2, and is a sheet having a width of about 550 mm and a length of about 2490 mm.

  Next, the reinforcing base material 11 is placed at the center position in both the width and length of the base waterproof sheet 13. Then, as a fixing process, a concrete screw 14 is driven from the upper surface of the reinforcing base material 11 so as to reach the roof 1. The concrete screw 14 has a diameter of 8 mm and a length of 130 mm, and is fixed so that it is generally screwed about 50 mm downward from the roof 1. The positions to be struck into the reinforced base material 11 are substantially the short center of the reinforced base material 11, and a plurality of positions are struck at equal intervals in the longitudinal direction. The number and interval of driving may be appropriately adjusted depending on how firmly the reinforcing base 10 is fixed. In addition, unlike the expandable anchor, the concrete screw 14 is good in workability if it uses a screw thread that fits into the concrete and does not require a pilot hole.

  Next, as a base waterproofing process, the reinforcement base material 11 is entirely encased from the bottom around the reinforcement base material 11 of the base waterproof sheet 13, and the joint waterproof tape 15 is attached to the joint. The seam waterproof tape 15 is an airtight waterproof tape based on a resin woven fabric used in roof construction. If the joint of the base waterproof sheet 13 is on the upper surface of the reinforced base material 11, the joint position is higher than that on the roof 1, which is desirable in terms of waterproofness.

  Next, a sheet metal process and a long sheet metal 16 covering the outdoor exposed portion of the reinforcing base material 11 as a cover metal sheet are covered, and the side surface of the reinforcing base material 11 is fixed with a sheet metal nail 18 subjected to waterproofing such as caulking. The longitudinal end portions of the base reinforcing material 11 are processed by folding the seams using end nose metal plates 17 as shown in FIGS. The long sheet metal 16 and the end sheet metal 17 are used as long steel sheet roofing materials, and plated steel sheets having a thickness of 0.35 mm were used.

  The installation of one reinforcing base 10 is completed by performing the above-described contact portion waterproofing step, fixing step, base waterproofing step, and sheet metal step. In the present embodiment, four reinforcing bases 10 are arranged at intervals of 1820 mm as a base for installing the solar cell module 20 shown in FIG.

  Since the reinforcing base material 11 which is the base material of the reinforcing base 10 is made of wood, it is lightweight, has a low weight burden on the roof 1, and has good workability. Although the waterproofness and durability cannot be obtained with wood as it is, the reinforcing base material 11 can be reliably waterproofed by the base waterproofing process. In addition, since the waterproof tape 12 or the sealing material is sandwiched between the base waterproof sheet 13 under the reinforcing base material 11 and the roof 1 in the contact portion waterproofing process, the seal portion is not exposed to the outside and deteriorates. Difficult and durable waterproofing is obtained. In addition, since the outdoor exposed portion of the base waterproof sheet 13 is protected by performing the sheet metal process, a reinforced base having high waterproofness and durability can be installed.

  Next, installation of the solar cell module 20 and the mount 21 on the reinforcing base 10 installed as described above will be described.

  The reinforced base 10 is provided with gantry fixing brackets 22 that are mounted at two or more locations in the longitudinal direction or at more locations. The gantry fixing bracket 22 is formed by bending a steel plate, and the gantry fixing bracket 22 is bent in a substantially rectangular horizontal part 22a in plan view on the reinforcing base 10 and the opposite sides of the horizontal part 22a in a plan view downward and upward. A pair of downward vertical pieces 22b and upward vertical pieces 22c are provided.

  The mounting bracket 22 is placed on the upper surface of the reinforcing base 10 at the horizontal portion 22a, the downward vertical piece 22b is positioned so as to sandwich the longitudinal side surface of the reinforcing base 10, and a plurality of lateral fixing holes are provided in the downward vertical piece 22b to fix it. The gantry fixing bracket 22 is fixed to the reinforcing base 10 with screws or the like whose holes are waterproofed from the horizontal direction.

  The upward vertical piece 22c of the gantry fixing bracket 22 is raised upward from the upper surface of the reinforcing base 10, so that the downward vertical piece 22b and the upward vertical piece 22c are orthogonal to each other in plan view.

  Front and rear gantry beams 23 connected to each gantry fixing bracket 22 of the plurality of reinforced bases 10 are provided, and the direction of the gantry beams 23 perpendicular to the reinforced base 10 is the longitudinal direction. The gantry beam 23 is a substantially U-shaped beam material of a thin steel plate that is opened downward, and is fixed so as to fit between the upward vertical pieces 22c of the gantry fixing bracket 22 from above.

  Here, the front side is a substantially south side where the solar cell module 20 faces the sun, and the rear side is a substantially north side opposite thereto. A short pedestal front leg 24 is erected on the front gantry beam 23, and a long gantry rear leg 25 is erected on the rear gantry beam 23. The gantry front leg 24 and the gantry rear leg 25 are made of U-shaped steel plate in plan view, and the lower ends thereof are fixed to the gantry beam 23.

  A tilted beam 26 is provided between the top of the mount front leg 24 and the mount rear leg 25. The frame inclined beam 26 is made of a U-shaped steel plate having a downward opening, and both ends thereof are fixed to the tops of the frame front leg 24 and the frame rear leg 25. In the embodiment, the distance from the upper surface of the reinforced base 10 to the upper ends of the gantry front leg 24 and the gantry rear leg 25 is about 600 mm and about 1200 mm, the distance between the gantry front leg 24 and the gantry rear leg 25 is about 1365 mm, and the tilt angle of the gantry inclined beam 26 Shown at about 30 degrees from the horizontal.

  A plurality of solar cell modules 20 are attached to the gantry inclined beam 26. In the embodiment, eight solar cell modules 20 having a size of 808 mm × 1580 mm are arranged in two rows and four rows. These are appropriately increased or decreased depending on the size of the roof 1 to be installed.

  By installing the solar cell module 20 and the base 21 on the roof 1 using the reinforcing base 10 as the base as described above, the weight and wind load can be distributed over the installation length of the reinforcing base 10 and installed on the existing roof. This will increase the possibility and contribute to the spread of solar cell modules. Moreover, since the installation of the reinforcing base 10 increases the strength of the roof itself, an improvement in earthquake resistance can also be expected.

  Next, a second embodiment of the present invention will be described. FIG. 10 is a diagram showing a method of installing the reinforcing base 30 according to the second embodiment of the present invention on the roof 1. The roof 1 is the same as that in the first embodiment.

  To install the reinforced foundation 30, mainly a long timber reinforced base material 31 as a base material of the reinforced base 30, a butyl tape 32 as a waterproof tape, a base waterproof sheet 33, a concrete screw 14, and a cover sheet metal A base sheet metal 36 is used. The specifications of the individual members of the present embodiment are the same as those of the first embodiment, and are omitted since the reinforcing base material 31 is the same as 11, the butyl tape 32 is 12, the base waterproof sheet 33 is 13, and the base sheet metal 36 is 16.

  First, as a base waterproofing process, the reinforcing base material 31 before installation is encapsulated all around with a base waterproof sheet 33. The seam of the encapsulated sheet is waterproofed with the seam waterproof tape 15 as in the first embodiment.

  Next, a double-sided adhesive butyl tape 32 having the same size as that of the bottom surface of the reinforcing base material 31 is attached to a location where the reinforcing base 30 is installed on the roof 1 as a contact portion waterproofing step. Then, the reinforcing base material 31 subjected to the base waterproofing process is placed on the butyl tape 32. At this time, the butyl tape 32 may be attached to the contact surface of the reinforcing base material 31 subjected to the base waterproofing process to the roof 1 and then placed on the roof 1.

  Next, as a fixing step, the reinforcing base material 31 subjected to the base waterproofing step is passed through the concrete screw 14 and fixed to the roof 1. Since a hole is made in the base waterproof sheet 33 on the reinforced base material 31 with the concrete screw 14, the hole is filled with a sealing material after being fixed and waterproofed.

  Next, as a sheet metal process, a long sheet metal 36 is placed on the outdoor exposed portion of the fixed reinforcing base material 31 and fixed to the side surface of the reinforcing base material 31 with a sheet metal nail 18 subjected to waterproofing such as caulking. This step is the same as in the first embodiment.

  The installation of the reinforcing base 30 according to the present invention is also completed by sequentially performing the above steps. The difference from the first embodiment is that the reinforcing base material 31 is encapsulated in advance with a base waterproof sheet 33 as a base waterproofing process, and the encapsulated reinforcing base material 31 is mounted on the roof 1 by performing the contact part waterproofing process. It is a point to put. By encapsulating the reinforcing base material 31 in advance, the amount of members carried into the installation site can be reduced, the construction time at the site can be shortened, and the installation cost can be reduced. As for the handling of the reinforcing base 30 after installation, outdoor equipment is appropriately installed as in the first embodiment.

  The present invention described above is not limited to the above-described embodiment, and various modifications can be made within the scope of the gist. For example, the base waterproof sheets 13 and 33 are not limited to asphalt roofing sheets, and may be waterproof sheets made of synthetic rubber, vinyl chloride, resin, or the like used for waterproofing the membrane.

  Moreover, although the example using the butyl tapes 12 and 32 as waterproof tapes in the contact portion waterproofing process is shown, a method of applying a sealing material such as a waterproof tape of acrylic resin, a caulking material, or a liquid gasket material may be used.

  Moreover, although the example using the gantry fixing bracket 22 to fix the gantry 21 on the reinforced base 10 was shown, the fixing structure to the reinforced base is not limited to this, and an L-shaped fixing member is attached to the upper surface of the reinforced base. It may be attached to and a frame or the like may be constructed thereon.
