Description

  The present invention relates to a guide rail accompanying installation and attachment of a solar panel.

  As a method of installing a solar panel, as shown in the invention disclosed in Patent Document 1, a frame body including a rectangular panel receiving material and a support column supporting the same is installed on a foundation, and the panel receiving unit is installed. Generally, a panel is placed on a material. The frame is made of steel with a certain weight so that it can withstand the weight of the panel and strong winds. For this reason, in the invention disclosed so far, the device has been devised to improve the workability and reduce the amount of steel used without losing the strength against wind pressure, and has achieved certain results.

  Patent Document 2 increases the number of parts for fastening the panel and the frame, and maintains the overall strength by combining the panel and the frame, not the panel or the frame, and the amount of steel used for the frame An invention for reducing the above is disclosed. In addition, the invention disclosed in Patent Document 3 secures the strength of the frame by a reinforcing structure in which X-type braces are installed between columns having the same height to support the panel receiving material, thereby reducing the thickness of the material used. . Furthermore, Patent Document 4 supports the rafters constituting the panel receiving material not only at the lower and upper parts but also at the central part from the lower direction, and enables the bending moment applied to the rafters to be reduced by supporting at three points. The material used has been reduced in weight.

  However, the invention of Patent Document 2 lacks versatility because it is designed to satisfy a predetermined strength standard as a whole in a state where the panel and the gantry are fastened. Moreover, since the number of fastening points is increased, it takes time to assemble. In addition, the inventions of Patent Documents 3 and 4 employ a special configuration such as incorporating braces or increasing the number of support posts in a part of the frame, and as a result, the assembly process increases accordingly. It takes time and effort. Further, if the steel frame is attached in an oblique direction, the screw holes are likely to be inconsistent.

  All of the previous installation methods, including the above-mentioned invention, employ a method in which a panel is placed on a receiver and screw holes are aligned and fastened. There are many problems caused by misalignment. In addition, in the method of placing the panel and connecting the panel from below with screws, the panel is removed from the frame by receiving wind pressure from below during tornadoes and typhoons, no matter how much the structure of the frame is strengthened. The danger of detachment cannot be wiped out.

  This invention solves the said subject, and makes it a subject to provide the panel holding fixture which is excellent in workability | operativity with a simple structure and is strong not only in the pressure from the upper direction but the pressure from the downward direction.

  In order to solve the above problems, the present invention replaces the conventional method of placing a panel on a panel receiver and fastening it with screws, and sandwiching the panel from both sides with a U-shaped box-shaped guide rail. adopt.

  One end of the U-shaped box-shaped guide rail is opened as an insertion port of the panel frame, and the other end is closed so that the inserted panel frame stops and forms a front wall portion.

  In addition, each guide rail comes into contact with each other in pairs, forming an H-shaped composite rail, and fastening members are installed in the vicinity of both ends of the composite rail. Each of the composite rails is arranged in parallel with the insertion opening obliquely upward while maintaining an interval equal to the horizontal width of the panel, and is assembled to two upper and lower columns installed horizontally with the fastening member.

  In an embodiment described later, the above-described two upper and lower support columns are assumed to be metal single tube pipes, and a clamp that can be held in a single tube in a short time is adopted as the fastening member.

  The solar panel inserts the left and right frames simultaneously through the guide rail insertion port installed in parallel. The frame is easily slid down by the guide rail, and is attached to the front wall to make a stop.

  By using the guide rail of the present invention, the time required for installing the solar panel is greatly reduced.

  Unlike the conventional panel-mounted frame, the guide rail according to the present invention sandwiches and holds the solar panel firmly from both sides, greatly reducing the risk of panel detachment during disasters such as tornadoes and typhoons. To do.

  In addition to the reduction in labor costs associated with the significant reduction in the time required for panel installation as described above, the absolute amount of necessary members such as steel is small compared to conventional frames, so the use of guide rails according to the present invention reduces the manufacturing cost. Reduction is realized.

It is a perspective view which shows the structure of the guide rail of this embodiment. It is a perspective view which shows the shape of each edge part of a guide rail. It is a conceptual perspective view which shows the clamp used as a fastening member in this embodiment, and its installation position. It is a perspective view which shows arrangement | positioning of the guide rail of this embodiment.

Hereinafter, an example of an embodiment of the present invention will be described with reference to the drawings.
First, the configuration of the present embodiment will be described.
The shape of the guide rail 2 according to the present invention is a U-shaped box shape as shown in FIG. 1, and the pair of guide rails 2 are back to back to form an H-shaped composite rail 1. The guide rail 2 includes a bottom surface portion 21 that forms a box-shaped bottom surface and a pair of side wall portions 22 that form longitudinal side surfaces. As shown in FIG. 2, one end of both ends is closed to form a side wall 23, and the other end is opened as an insertion port 24 for the solar panel.

  As shown in FIG. 4, the guide rails are arranged such that a pair of guide rails 2, that is, H-shaped composite rails 1, are placed at the same interval as the width of the panel, with the U-shaped open surfaces facing each other. The mouth 24 is disposed obliquely with the upper side being obliquely upward.

  In the present embodiment, the composite rail 1 is fastened to two struts 4 arranged vertically, and the strut 4 is assumed to be a single pipe. The two single pipes 4 are arranged parallel to the ground with a level difference, and the distance between each pipe is set to be equal to the distance between the clamps of the guide rail 2 described later. (FIG. 4). As a fastening member to the single pipe 4, as shown in FIG. 3, a nut-clamped clamp 3 that can be attached with one touch is adopted.

  Specifically, clamps 3 are fixed to two locations in the vicinity of the ends on the outside of the side wall of the pair of guide rails 2, that is, the H-shaped composite rails 1 (FIGS. 1 and 3). Fastening to the single pipe 4 can be performed quickly in a short time.

The procedure for installing solar panels is as follows. (1) Insert the frame of the panel from the insertion port 24 while aligning the left and right positions of the tip. (2) Slide the panel diagonally downward. (3) When the front end of the panel is attached to the side wall portion 23, the whole is stopped.
In this state, the bottom surface portion 21 and the side wall portion 22 of the guide rail 2 are sandwiched between the frame of the panel, and the solar panel is securely held from both sides.

  As described above, when installing the panel, since there is no conventional screwing process to the frame, many panels can be installed in a short time.

  The features and advantages of the present invention have been described in the above embodiments with details of the configuration and functions of the invention, but the present invention is within the scope of the principles of the present invention and within the scope of the claims of the present application. It is possible to extend the words used to a broad and general meaning, and to change the details, especially the arrangement of guide rails, members, etc. For example, in this embodiment, the guide rails 2 are back to back to form an H-shaped composite rail 1. In the invention of claim 1, the guide rails 2 are not formed in an H shape and are arranged apart from each other while maintaining a U shape. Also good. When a single pipe is not used for the support, it is possible to use a fastening member that is compatible with a support that is not a clamp.

  Further, within the scope of the principle of the present invention, screwing is not necessary for installing the solar panel on the guide rail, but from the viewpoint of preventing the installed solar panel from being stolen, several screws are used. Sometimes it is desirable. The position and number of screwing in this case are arbitrary by the practitioner of the present invention.
