  In order to install facilities such as a solar power generation device on a roof on which a waterproof layer and a heat insulating layer are laid, a base is often provided in advance on the base of the roof. For example, in the case of RC (steel reinforced concrete) foundations, a base frame is manufactured using a formwork at the same time as the base is manufactured, and after the foundation frame is completed, the waterproof material is cut according to the shape and bonded to form a waterproof layer. To do. This method has a problem that it takes cost and a work period because the foundation frame is manufactured on site. In addition, when multiple rectangular foundation mounts are installed, complex parts occur, and the waterproof material is cut and bonded to accurately form and process the waterproof layer according to the position, shape, dimensions, etc. of the multiple foundation mounts. There was a problem that construction had to be difficult. Further, when the waterproof layer is processed in accordance with the rectangular base frame, the strength of the waterproof layer is weak at the corners, and there is a risk that the portion is damaged due to aging and water leaks. In addition, as shown in Patent Document 1 and Patent Document 2, if a pedestal is provided with H steel or the like on the roof surface, the shape of the waterproof layer is further complicated, and the processing of the waterproof layer and the heat insulating layer becomes more difficult.

  On the other hand, after laying a waterproof layer on the roof, the pedestal may be placed and fixed directly on the waterproof layer. There was a danger. Also, the service life of the waterproof layer and the solar panel is usually different. When the waterproof layer having a short service life is repaired, the installed solar panel is removed and only the waterproof layer is repaired depending on the situation. However, when the waterproof layer is a PVC sheet, it is not possible to make a repair to cover the PVC sheet anew, so that it is necessary to remove the PVC sheet and the frame installed on the PVC sheet. For this reason, there is a problem that the cost of the renovation work becomes high and the period becomes long.

  Therefore, an object of the present invention is to provide a pedestal that can be easily and firmly installed on a roof and that is easy to lay a waterproof layer or the like and hardly leaks water.

  In order to achieve the above object, the invention according to claim 1 is a gantry for installing equipment on a roof in which an upper layer is laid on an outer surface of a base, the substrate fixed to the base, Standing on a substrate, penetrating through the upper layer and projecting from the upper layer, and supporting columns supporting the equipment and attached to the supporting columns in parallel to the substrate at intervals corresponding to the thickness of the upper layer And a rack.

  The invention according to claim 2 provides the gantry according to claim 1, wherein the support column is a cylinder or an elliptical column.

  The invention according to claim 3 is a mount according to claim 1, which is applied to a roof having a waterproof layer on the upper layer, and is attached to the support column above the flange, and the flange A pedestal is further provided with a presser that holds and holds a waterproof layer therebetween.

  If the gantry of the present invention is used, the substrate is directly fixed to the base of the roof, so that the gantry can be easily fixed and firmly fixed to withstand the load and wind pressure of the equipment. Moreover, since only the support pillar which supports an installation has come out on the outer surface of a roof, the magnitude | size of the hole which must be processed into a waterproof layer becomes small, for example, and a process becomes easy. Therefore, it is possible to shorten the construction period for installing facilities and the like.

  In addition, since the support column is provided with flanges at intervals corresponding to the thickness of the upper layer, the hole of the layer through which the support column penetrates can be blocked by sandwiching the upper layer with the flange, thereby preventing water leakage Can do. In other words, the gantry can be firmly fixed to the roof and provided without lowering the waterproof performance of the waterproof layer.

  In addition, if the cross section of the support column is made simple, for example, a circle or an ellipse, there will be no risk of damage to the waterproof layer due to aging because corners do not occur in the processed portion of the waterproof layer and there are no weakened portions. Decrease.

  Moreover, by using a pressing tool, it is possible to close a hole formed in the waterproof layer, prevent damage due to secular change, and prevent water leakage.

It is a figure which shows the mount frame by this invention, (a) is a top view, (b) is an elevation view. It is a perspective view which shows the condition which fixed the mount frame by this invention to the roof, and installed the solar power generation device.

  Hereinafter, a gantry according to an embodiment of the present invention will be described with reference to FIGS. 1 to 3. As shown in FIG. 3, the gantry 10 according to the present embodiment is a gantry for installing the solar power generation device 50 on the roof 30. The solar power generation device 50 is installed via a plurality of mounts 10 and rails 52 fixed to the roof 30. The roof 30 as a target in the present embodiment is waterproofed by a heat insulating exposed waterproofing method, and has a steel deck 36 as a base as shown in FIG. 1 (a), a heat insulating layer 34 on its outer surface, and its outer surface. The waterproof layer 32 is laid. In the present embodiment, the base is a steel deck, but the base may be any base that can form a waterproof layer, such as RC (steel reinforced concrete), PC (precast concrete), ALC (lightweight cellular concrete). The roof 30 is attached to the H steel 40 via a roof mount 38. Since the heat insulating exposed waterproof construction method and the structure of the roof 30 are general, detailed description thereof is omitted.

  The gantry 10 includes a base plate 12 fixed to the outer surface of the steel deck 36, a support column 16 erected substantially perpendicular to the surface of the substrate 12, and a waterproof collar 14 ( An example of a buttocks). The waterproof collar 14 is provided substantially parallel to the substrate 12 at a height (separation interval H) that is substantially the same as the thickness of the heat insulating layer 34. In consideration of durability and weather resistance, the gantry 10 is desirably made of metal, and the gantry 10 of the present embodiment is made of stainless steel. As shown in FIGS. 2 (a) and 2 (b), the substrate 12 and the waterproof collar 14 are flat plates formed in a substantially square shape, and a cylindrical support column 16 is erected at the center thereof. Yes. Therefore, the cross section of the gantry 10 has a “earth” shape as shown in FIGS. 1 (a) and 2 (b).

  A mounting hole 13 is formed in the outer peripheral portion of the substrate 12 as shown in FIG. 2A, and can be firmly fixed to the steel deck 36 by screwing with a dedicated screw, for example. The lower end of the support column 16 is welded to the substrate 12 and is firmly joined. On the other hand, a screw thread 17 is formed on the upper portion of the support column 16. For example, an equipment support 20 connected to the rail 52 is screwed so that the vertical level can be adjusted. As described above, the waterproof collar 14 is attached to the support column 16 at substantially the same height as the thickness of the heat insulating layer 34, and the entire joint is prevented from leaking from the hole formed in the waterproof layer 32. In FIG.

  The waterproof collar 14 has a flat shape as a whole, and the size of the waterproof collar 14 is a part that is laminated with the waterproof layer 32 (the length from the side surface of the support column 16 to the end of the waterproof collar) in order to maintain waterproof performance. Now, it is formed so that the range of D in FIG. On the other hand, the substrate 12 is formed wider than the waterproof collar 14 in this embodiment, but the area of the substrate 12 may be smaller than the waterproof collar 14 as long as it can be fixed with a required strength by screwing. Absent. Further, the substrate 12 and the waterproof collar 14 may have different shapes.

  The gantry 10 of the present embodiment further includes a pressing member 18 that holds the periphery of the hole formed in the waterproof layer 32 on the support column 16. The presser 18 is an annular stopper, and a hole having the same shape as the cross section of the support column 16 is formed in the center. Further, as shown in FIG. 1B, the presser 18 has a shape in which the periphery of the hole is pushed up so that the seal material 19 can be filled. After laying the waterproof layer 32, the sealing material 19 is filled in the joint between the support column 16 and the waterproof layer 32, and the presser 18 is fixed to the support post 16 through the hole of the presser 18. The sealing material 19 prevents rainwater and the like from entering the hole, and the waterproof layer 32 is pressed by the outer edge portion of the presser 18, so that the waterproof layer 32 is not damaged and swollen due to secular change and prevents water leakage. can do.

  The installation procedure of the gantry 10 according to the present embodiment and the laying procedure of each layer will be described. When the base of the roof is completed, the gantry 10 is placed in a predetermined place and fixed by screwing. Next, a heat insulating material 34 is laid and a heat insulating layer 34 is laid. Since there is a gap formed between the substrate 12 and the waterproof collar 14 so as to have substantially the same thickness as the heat insulating material, the heat insulating material is inserted from the lateral direction at the place where the gantry 10 is fixed. 34 is laid. Next, for example, an asphalt waterproof sheet is laid on the heat insulating layer 34 to form the waterproof layer 32. In the place where the gantry 10 is fixed, a hole having the same shape as the cross section of the support column 16 is formed in the asphalt waterproof sheet, and the support column 16 is passed through the hole and covered with the asphalt waterproof sheet. Finally, as shown in FIG. 1 (a), the waterproof layer 32 is laid so as to overlap the waterproof collar 14, and the waterproof layer 32 is exposed on the outer surface of the roof and the support column 16 protrudes. Become. After the roof is completed, the facility support 20 is screwed to the support column 16 to adjust the upper and lower levels, the rails 52 and the like are arranged, and the solar power generation device 50 is installed.

  Thus, since the prefabricated gantry 10 can be fixed to the steel deck 36 by screwing and the roof can be constructed, the construction period is shorter than that of a conventional concrete gantry that requires the production of a formwork and a curing period. Can be shortened. Further, the support pillar 16 is a cylinder, and the waterproof layer 32 can be easily laid by simply making a circular hole in the waterproof layer 32 according to the position, and according to the shape of the complex part as in the past. There is no need to process the waterproof layer 32. Further, the waterproof collar 14 of the gantry 10 is provided immediately below the hole formed in the waterproof layer 32. Since the waterproof layer 32 and the waterproof collar 14 are overlapped in a predetermined range, water leakage is caused. Can be prevented. Further, since the joint between the waterproof layer 32 and the support column 16 is closed by the presser 18, it is possible to avoid a vacancy in the waterproof layer 32 and a water leakage accident due to secular change.

  When the roof is renovated, the gantry 10 of the present embodiment is fixed to the base of the roof, so that only the layer that needs to be repaired can be removed and repaired without removing the gantry 10. Also, depending on the repair method, a new layer may be stacked and repaired without removing the old layer. Therefore, it is desirable that the height of the support column 16 is as high as possible. However, considering the risk of the support column 16 buckling, it is necessary to adjust the strength by increasing the thickness of the support column 16 according to the weight of the equipment to be installed. is there.

  The embodiments of the present invention have been described above with reference to the accompanying drawings. In addition, although this embodiment described the case where a solar power generation device is installed, the mount 10 of this invention can be used also for installation of facilities other than a solar power generation device, for example, an outdoor antenna. Moreover, in this embodiment, although the shape of the board | substrate 12 and the waterproof collar part 14 was made into the substantially square shape, it may be a triangle, a polygon, or a circle according to the installation place. However, in order to ensure waterproof performance, the waterproof layer 32 and the waterproof collar 14 need to overlap each other over a predetermined range.
