Description

  The present invention relates to a land roof mount, and more particularly to a mount used when a solar panel or the like is installed on a land roof formed of concrete or the like.

  Devices that use solar energy effectively, such as solar panels, are often installed on the roof in order to prevent light that strikes them from being disturbed by other structures. Of these, in general roofs, the roof itself has a certain degree of inclination, so it may be simply installed along the roof. It is necessary to turn diagonally toward the sun.

  Conventionally, as a platform for a flat roof used in a solar panel or the like, what is obtained by welding legs having different lengths to a platform member during work has been widely used. However, such a platform is manufactured on the assumption that it will be installed on a flat surface in the workplace, so if there is a slight inclination caused by drainage or construction in the place where it is actually installed, it will be tight. In some cases, it is necessary to devise such as sandwiching inclusions for adjustment.

  In addition, after the legs are welded to the gantry member, there are problems such as taking up space for storage and transportation, and problems such as difficulty in handling during installation. Furthermore, there is a problem in that the entire base must be replaced even if a part of the base is corroded when the base is welded to the base member.

  Therefore, there has been a demand for the development of a flat roof mount that can be easily installed even if the flat roof is not completely flat, can be stored and transported easily, and is easy to handle.

  As a result of diligent research to solve the above problems, the present inventors have made it possible to bend a leg attached to a gantry member and fix it at an installation site, so that it can be installed even if the flat roof is not exactly horizontal. I found out. Further, it has been found that even when the gantry member is long and a support leg is required in the middle, if the support leg can be adjusted, it can be firmly installed without wobbling.

  That is, the present invention includes a gantry member, two legs having different lengths, and four plates that connect the gantry member to each leg, and each of the plates is fixed to the gantry member, and the two legs are A rooftop pedestal that is pivotally attached to each of the two plates by bolts and nuts, and further provided with holes that can be fixed to the plates and the legs by bolts and nuts, respectively. In the front, the two legs are folded in parallel with the gantry member. At the installation site, the two plates and each leg are fixed with nuts through bolts in the holes, and the legs are pivotally attached. By mounting and tightening the bolts and nuts that have been used, the gantry member and the leg can be fixed via the plate.

  Further, according to the present invention, two intermediate plates are fixed to the gantry member between the two legs of the gantry member, and the bolt and nut tightening position can be adjusted to the vertical position on the intermediate plate. The intermediate leg is pivotally attached to the hole with bolts and nuts. Before installation, the intermediate leg is folded in parallel with the gantry member, and the intermediate leg is opened at the installation site. In the above-mentioned rooftop gantry, the gantry member and the intermediate leg are fixed via the intermediate plate by adjusting the position and tightening the bolts and nuts attached to the intermediate leg so as to be rotatable.

  The flat roof mount according to the present invention can be bent at the legs attached to the mount member. Therefore, compared to the conventional welded mount, it is easy to handle without taking up space during storage or transportation, and even when installed. Furthermore, it can be partially exchanged.

  Moreover, in the flat roof mount frame of the present invention to which the intermediate legs are attached, the flat roof surface to which each leg is attached can be reliably attached even if it is not completely horizontal.

  The present invention will be described below with reference to the drawings showing some embodiments of the present invention.

  FIG. 1 is a drawing showing a use state of a flat roof mount (hereinafter referred to as a “mount”), FIG. 2 is a drawing showing a state in which the legs of the stand of the present invention are folded, and FIG. FIG. 4 is a drawing showing the fixed state on the short leg side. In the figure, 1 is a frame, 2 is a frame member, 3a is a long leg, 3b is a short leg, 4 is a plate, 5 is a fixing means, 6 is a rotating bolt / nut, 7 is a plate side hole, 8 is a leg side hole , 9 is a fixed foot, 10 is an angle mounting bolt, 12 is a through bolt / nut, A is a mounting angle, and B is a solar panel.

  As shown in FIG. 1, the gantry 1 of the present invention is provided with an angle A thereon and is used as a base for holding a solar panel B or the like obliquely. The base 1 in this figure is shown having a leg in the middle, and the number thereof is three. However, the number is not limited to this, and there is no need for the intermediate leg. An appropriate number of two or more can be used.

  FIG. 2 is a drawing showing a folded state of the most basic gantry 1 having two legs. The gantry 1 according to the present invention is such that legs 3 are attached to both ends of a gantry member 2 via plates 4. In this state, the gantry member 2 and the plate 4 are both fixed by the fixing means 5. In this embodiment, bolts and nuts are used as fixing means, but fixing means such as welding or rivets may be used.

  On the other hand, the long leg 3a and the short leg 3b are rotatably attached to the plates 4a and 4b by means of rotating bolts and nuts 6, respectively. Here, “attached so as to be rotatable” refers to a state in which the operator can move by applying a certain amount of force, although it does not rotate in a natural state.

  The plates 4a and 4b are provided with plate side holes 7 for fixing to the legs 3a and 3b, respectively, and the other legs 3a and 3b are also provided with leg side holes 8 corresponding to the plate side holes 7. At the time of installation, the bolts and nuts 12 are passed through these holes coming in the same position with the legs 3 open, and fixed by tightening.

  Furthermore, fixing legs 9a and 9b for stably fixing the gantry 1 to the ground surface are attached to the lower part of the long legs 3a and the short legs 3b, and anchor bolts (not shown) or the like are used to fix the concrete surface. The gantry 1 is fixed at an installation position such as. Furthermore, on the gantry member 2, an angle mounting bolt 10 is attached toward the upper part, and an attachment angle A is installed here, so that a solar panel B or the like can be installed.

  Next, the installation state of this invention mount frame 1 is demonstrated using FIG. 3 and FIG. The gantry member 2 and the leg 3 are each cut off obliquely at the top, and the cut-out portions abut on each other as indicated by dotted lines in a state where the bent leg 3 is opened. In this state, the plate-side hole 7 and the leg-side hole 8 come to the same position, so these two holes are fixed with the through bolts and nuts 12. Further, by further tightening the rotating bolt / nut 6 which is attached so as to be rotatable, the whole is stably fixed.

  In the gantry of the present invention, a position adjusting mechanism as shown in FIG. 5 may be provided on at least one of the fixed legs on any one of the legs. The position adjusting mechanism in FIG. 5 is provided with two oval or jade-shaped adjusting holes 13 on the rising surface of the fixed foot 9b, and this bolt and nut 14 (the bolt protrudes from the bottom (leg side)). By fixing the adjustment hole 13 in a sandwiched manner, the vertical position can be adjusted.

  Next, the frame 1 of the present invention having a leg in the middle will be described with reference to FIGS. 6 and 7. FIG. 6 is a perspective view of the gantry 1 according to this embodiment, and FIG. 7 is a side view of the intermediate leg portion. In the figure, 15 is an intermediate leg, 16 is an intermediate plate, 17 is an adjustment hole, and 18 is a rotating bolt / nut.

  First, the intermediate plate 16 is fixed to the gantry member 2 by the fixing means 5. The intermediate plate 16 is provided with an oval or jade-shaped position adjusting hole 17, and the intermediate leg 15 is rotatably attached to the adjusting hole 17 by a rotating bolt / nut 18. . Needless to say, the fixed leg 9c is provided on the intermediate leg 15 in the same manner as the long leg 3a and the like, and an adjusting mechanism may be provided on the fixed leg 9c.

  The fixing of the intermediate leg 15 is performed as follows. First, the rotation bolt / nut 18 attached so as to be rotatable is loosened and adjusted so that the upper end surface 20 of the intermediate leg 15 contacts the lower surface of the gantry member 2. In this position, when the rotating bolt / nut 18 is tightened, the intermediate leg 15 is fixed to support the gantry member 2.

  Note that the gantry 1 using the intermediate legs 15 is generally long in length, and as a result, the height of the long legs 3a is also increased, and it is assumed that the legs 1 are likely to fall over. In such a case, it is preferable to connect a plurality of long legs 3a with a reinforcing material (not shown) to increase the strength. As such a reinforcing material, a metal strip or a metal wire is used, and the installation is preferably made at an angle connecting the upper part of the long leg 3a and the lower part of the adjacent long leg 3a.

  According to the present invention described above, the gantry 1 can be stored and transported with the legs 3 folded, so that it is easier to handle than the conventional one manufactured by welding.

  In addition, since the length of each leg can be adjusted, it is possible to reliably attach the surface of the land roof to which each leg is attached, even if the surface is not completely horizontal.
