  When performing maintenance, inspection, painting, dismantling, construction, etc. on structures such as bridges and buildings, the morning glory panel is attached to a temporary structure assembled around the structure with an inclination angle with respect to the vertical direction. The morning glory panel partitions the work space from the external space. Such a morning glory panel is disclosed in Patent Document 1 below.

Japanese Patent Laid-Open No. 2008-115644 (FIG. 10)

  When the morning glory panel is attached to the temporary structure, the work space formed by the temporary structure becomes a space that is blocked or substantially blocked from the external space by the morning glory panel.

  An object of the present invention is to provide a morning glory panel for a temporary structure that can ensure the air permeability of a work space formed by the temporary structure even when attached to the temporary structure.

  The morning glory panel for a temporary structure according to the present invention is a temporary morning glory panel that is attached to the temporary structure with an inclination angle with respect to the vertical direction. Is provided.

  Since the morning glory panel for a temporary structure according to the present invention is provided with an opening that penetrates in the panel thickness direction and allows ventilation, the work space formed by the temporary structure is an external space. Therefore, the work environment of the work space can be improved because the air permeability can be secured between the work space and the external space.

  In the present invention, the term “ventilated” means that not only air circulation is ensured, but also smoke circulation and dust circulation are ensured. .

  In the present invention described above, the opening may be always open, but it is preferable that the opening can be opened and closed by the lid.

  When the opening can be opened and closed by the lid as in the latter case, for example, when it becomes necessary to close the normal opening with the lid and ventilate the work space, etc. By opening the opening, the air permeability of the opening can be ensured, and the opening can be selectively opened and closed as necessary.

  In addition, when the opening can be opened and closed by the lid as described above, the opening can be opened and closed by the lid by attaching and removing the lid to the morning glory panel according to the present invention. Alternatively, the lid body may be attached to the morning glory panel according to the present invention so that it can be opened and closed with the hinge for opening and closing as the center.

  According to the latter, since the lid is attached to the morning glory panel according to the present invention by the hinge for opening and closing so as to be freely opened and closed, the handleability of the lid can be improved.

  Further, the lid body may be composed of a single lid member, or the lid body may be formed by a plurality of lid members that are foldably connected via a folding hinge.

  When the lid is formed by a plurality of lid members that are foldably connected via folding hinges as in the latter case, the lid body has a total area of the plurality of lid members. The area of the body can be increased, and therefore the opening that can be opened and closed by the lid can also be increased, thereby ensuring sufficient air permeability through the opening.

  Moreover, it is preferable that the morning glory panel according to the present invention is provided with a lid stopper for stopping the lid when the hinge is opened and rotated around the opening / closing hinge.

  According to this, since the lid with the opening opened can be stopped in the opened state with the lid stopper, the opening of the opening can be maintained.

  Moreover, it is preferable that the opening provided in the morning glory panel according to the present invention is in a state of being blocked by a cover formed including a porous member.

  According to this, even if an opening is provided in the morning glory panel according to the present invention, which is a member that partitions the work space and the external space, for example, an article such as a work tool pops out from the work space to the external space. It can be prevented by the cover, and the air permeability of the opening can be ensured by the porous member.

  The porous member may be, for example, an expanded metal, a punching metal, a metal mesh member, or any material as long as a large number of small holes are formed. .

  In the present invention, the cover may be fixedly attached to the morning glory panel according to the present invention, or may be arranged on the morning glory panel according to the present invention so as to be slidable in the direction of opening and closing the opening. .

  When the cover body is slidably arranged in the morning glory panel according to the present invention so as to open and close the opening portion, a part or all of the opening portion is covered with the cover body by the sliding slide of the cover body. Since it can be set as the location which is not obstruct | occluded, an electrical wiring etc. can be penetrated to an opening part in this location here.

  Further, when the cover body is slidably disposed in the morning glory panel according to the present invention so as to be slidable in the opening / closing direction, the cover body is elastically biased in the direction of closing the opening section by the elastic member. You may do it.

  According to this, even if the cover is slid in the direction to open the opening, the cover naturally slides in the direction to close the opening by the elastic biasing force of the elastic member, so that it is possible to avoid forgetting to close the cover. Even if the electrical wiring or the like is inserted into the opening, the closing slide of the cover stops at the location of the electrical wiring, so only the portion of the opening where the electrical wiring or the like is not inserted is used. It becomes possible to make it the state shielded with the cover.

  The overall shape of the morning glory panel according to the present invention described above can be an arbitrary shape according to the shape or structure of the temporary structure to which the morning glory panel is attached, and an example of the overall shape is a vertically long rectangle. It is.

  As described above, when the morning glory panel according to the present invention is formed into a vertically long rectangle, the two openings described above may be provided at both sides of the central portion or the substantially central portion in the length direction.

  According to this, even if the morning glory panel according to the present invention is turned upside down, it can be used.

  The overall shape of the morning glory panel according to the present invention may be a horizontally long rectangle, a square, a triangle, an inverted triangle, a trapezoid, an inverted trapezoid, or the like.

  Furthermore, the morning glory panel according to the present invention can be used at various work sites where temporary structures are assembled. That is, this work site is a work site where maintenance and inspection of structures such as bridges and buildings are performed. However, it may be a work site where painting is performed, a work site where dismantling is performed, a work site where construction is performed, or a civil engineering work site.

  According to the present invention, it is possible to obtain an effect that air permeability of a work space formed by a temporary structure can be secured.
