  Next, a pair of guide rails 8 is prepared (Step S2). As described with reference to FIG. 10 and the like, the guide rail 8 has a groove 26 formed on the inner surface 25 to slide the panel 4.

  Next, the lower frame 10 is fixed to the lower ends of the pair of guide rails 8 (Step S3). Specifically, the pair of guide rails 8 and the lower frame 10 are fixed to each other using the fixing member 30 described above. The description of the fixing method is omitted.

  Next, the outer frame portion 16 of the first panel 4 is inserted into the groove 26 of the pair of guide rails 8 (Step S4). As described above, since the inclined portion 28A is provided at the entrance of the groove 26, the panel 4 can be easily inserted. By sliding the inserted panel 4 in the A1 direction along the groove 26, the panel 4 comes into contact with the lower frame 10 fixed to the lower end of the guide rail 8.

  When the operator operates the panel 4, he or she works while holding the handle 18 of the panel 4. Since the panel 4 is long in the direction B intersecting the direction A, which is the arrangement direction, the panel 4 can be easily inserted when the operator inserts the panel 4 into the guide rail 8.

  Next, the outer frame portions 16 of the second and subsequent panels 4 are sequentially inserted into the grooves 26 of the pair of guide rails 8 (step S5). In the present embodiment, the second to fourth panels 4 are sequentially inserted into the grooves 26 of the guide rail 8. Thereby, as shown in FIG. 1 and the like, the four panels 4 can be held in a state of being arranged in a line along the direction A in which the guide rail 8 extends.

  Next, the upper frame 12 is fixed to the upper ends of the pair of guide rails 8 (Step S6). Specifically, the pair of guide rails 8 and the upper frame 12 are fixed to each other using the fixing member 40 described above. The description of the fixing method is omitted.

  Next, the guide rail 8 is installed on the temporary scaffold (Step S7). Specifically, the operator holds a pair of guide rails 8 (FIG. 1) to which the lower frame 10 and the upper frame 12 are fixed so as to protrude obliquely upward from the outer surface of the temporary scaffold and fix them.

  By executing the above-described steps S1-S7, the morning glory device 2 in which the plurality of panels 4 are arranged in a line along the direction A can be installed on the outer surface of the temporary scaffold so as to project obliquely upward.

  As described above, the morning glory device 2 installed on the temporary scaffold to receive the falling object according to the present embodiment includes a plurality of panels 4, a pair of guide rails 8, a lower frame 10, and an upper frame 12. Prepare. The pair of guide rails 8 are installed on the outer surface of the temporary scaffold so as to project diagonally upward. The plurality of panels 4 are sandwiched and held by a pair of guide rails 8, and are arranged in a line along the direction A in which the guide rails 8 extend. The lower frame 10 is fixed to lower ends of the pair of guide rails 8 and supports the panel 4. The upper frame 12 is fixed to upper end portions of the pair of guide rails 8. In such a configuration, a groove 26 is formed on the inner side surface 25 of the guide rail 8 so as to slidably hold the plurality of panels 4 in the direction A, which is the arrangement direction. In addition, each panel 4 includes a panel body 14 and an outer frame 16 surrounding the outer periphery of the panel body 14. The outer frame 16 is held in the groove 26 of the guide rail 8.

  Further, the method for installing the morning glory apparatus 2 of the present embodiment includes a step of preparing a plurality of panels 4 each including the panel body 14 and the outer frame 16 surrounding the outer periphery of the panel body 14 (step S1). The method further includes preparing a pair of guide rails 8 having grooves 26 formed on the inner side surfaces 25 and a lower frame 10 fixed to lower end portions of the pair of guide rails 8 (steps S2 and S3). The method further includes a step of sequentially inserting the plurality of panels 4 into the grooves of the pair of guide rails 8 and sliding them, and arranging them in a line along the direction in which the guide rails 8 extend (steps S4 and S5). The method further includes fixing the upper frame 12 to the upper ends of the pair of guide rails 8 (Step S6).

  According to such a configuration / method, a plurality of panels 4 can be sequentially arranged by sliding the panels 4 with respect to the guide rails 8 in order. Thus, the panel 4 can be installed with a simple operation, and the installation operation can be easily performed. Further, by forming the panel 4 by the panel main body 14 and the outer frame 16, even when the panel main body 14 has a shape (for example, a wavy shape) that reinforces the strength, the outer frame 16 is guided. If the rail 8 is engaged with the groove 26, it can be slid.

  Note that the present invention is not limited to the above embodiment, and can be implemented in other various modes. For example, in the embodiment, the case where four panels 4 are used has been described. However, the present invention is not limited to such a case, and an arbitrary number of panels may be used as long as a plurality of panels 4 are used. Further, in the embodiment, the case where the panel main body 14 of the panel 4 has a shape waving in the A direction has been described. However, the present invention is not limited to such a case, and may have an arbitrary shape such as a flat plate shape. Further, any material may be used as the material of the panel body 14 and the outer frame 16.

  Although the present invention has been fully described in connection with the preferred embodiments thereof with reference to the accompanying drawings, various changes and modifications will be apparent to those skilled in the art. It is to be understood that such changes and modifications are included therein unless they depart from the scope of the invention as set forth in the appended claims.
