Description

  The present invention relates to a guard fence, and more particularly to a guard fence in which a panel body can be replaced.

  Conventionally, guard fences (protective fences) have been installed as temporary enclosures around construction sites and construction sites to prevent people from entering.

  As described in Patent Document 1, such a guard fence is provided on the inner side of a frame body composed of a pair of vertical frame members (vertical members) and a plurality of horizontal frame members (horizontal members) connecting them in the horizontal direction. A plurality of attachment bodies are fixed, and a metal marking plate (panel body) is attached to the attachment bodies via attachments such as screws.

  However, there are only a small number of attachments, such as 3 or 4, on one side of the marking body, and the marking body is made of a thin metal plate in consideration of replacement work. In the intermediate portion, a gap is generated between the frame body and the sign body. For this reason, when moving the guard fence, a finger may be caught in the gap to cause injury.

  Therefore, in the technique described in Patent Document 1, a gap body made of a sponge-like material or the like is attached to the gap between the frame body and the marking plate so that a finger is not inserted into the gap.

Registered Utility Model Publication No. 3191748

  However, in the technique described in Patent Document 1, when the sign plate is attached, it is placed on the attachment body and supported and aligned. However, the sign body is supported only at a small attachment piece, so that it bends. Therefore, the marking body is not stably supported by the frame body, and the alignment is difficult.

  Furthermore, since the work for attaching the gap body is required in addition to the work for attaching the sign body to the frame like a normal guard fence, the work at the time of attachment increases. In addition, when the sign body is replaced, the work for removing and remounting the gap body is required, so that the work for replacement also increases.

  In view of the above points, the present invention has a closed gap between the frame body and the panel body, and can stably support the panel body on the frame body at the time of attachment. An object of the present invention is to provide a guard fence in which the panel body replacement work does not increase as compared with a normal case.

  The present invention is composed of a plurality of vertical metal members extending in the vertical direction and a plurality of horizontal metal members fixed so as to extend in the left-right direction between the plurality of vertical members. A frame having at least one rectangular space surrounded by the two vertical members and the two horizontal members in view, a rectangular panel body in front view, and the two surrounding the space Extending vertically along the longitudinal direction of each of the vertical members, welded to the two vertical members so as to protrude toward the space side, and two vertical mounting pieces made of a metal flat plate, The two cross members that extend along the longitudinal direction of the two cross members surrounding the space, are welded to the two cross members so as to protrude toward the space side, and are formed of two metal flat plates. A horizontal mounting piece, and the vertical mounting piece and the horizontal mounting piece in the direction in which the vertical mounting piece and the horizontal mounting piece extend in the front view; In a portion where the outer peripheral portion of the panel member is in contact, characterized in that it comprises a fixing means for mechanically fixing the the longitudinal mounting piece or the lateral mounting piece and said panel member.

  According to the present invention, each of the two vertical members and the two cross members surrounding the rectangular space of the frame is extended in the longitudinal direction of the two vertical members and the two cross members. The vertical mounting piece and the horizontal mounting piece are welded so as to exist and protrude toward the space. The panel body is mechanically fixed to the vertical mounting pieces or the horizontal mounting pieces by fixing means.

  As a result, just by fixing the panel body with the fixing means to the frame body to which the vertical mounting piece and the horizontal mounting piece are welded, the gap between the frame body and the panel body is vertical in the front view. It is closed by the mounting piece and the lateral mounting piece. Therefore, it is possible to eliminate the possibility of a finger being caught in the gap and causing injury. Note that the position of the space in which the panel body is arranged is not limited, and for example, a wire net may be stretched in the space in which the panel body is not arranged.

  Further, when the panel body is attached to the frame body, the panel body is bent because the outer peripheral portion of the panel body is in contact with the extending direction of the vertical mounting piece and the horizontal mounting piece welded to the frame body. And stably mounted on the vertical mounting piece and the horizontal mounting piece. Thereby, the alignment of the panel body with respect to the frame body is also facilitated.

  Therefore, the panel body can be easily attached to the frame body as compared with the conventional case. Furthermore, since it is not necessary to attach a gap body after the panel body is attached to the frame body as described in Patent Document 1, the mounting work and the panel body replacement work are not increased.

  In the present invention, a through hole is formed in the outer peripheral portion of the panel body, a through hole is formed in each of the vertical mounting piece and the horizontal mounting piece, and the fixing means includes a through hole of the panel body and the mounting piece. It is preferable to include a plurality of fastening bolts inserted through the through holes and fastening nuts respectively screwed into the plurality of fastening bolts.

  In this case, since the fixing means includes the fastening bolt and the fastening nut, the panel body can be easily fixed to and released from the frame body.
