Description

  The present invention, for example, among the handrails provided on the outside of a concrete slab that becomes a balcony or an external corridor of an apartment house, a plurality of handrail pillars are erected at the rising part of the nose of the concrete slab, and the upper ends of these pillars A panel is mounted on the base, and a panel mounting bracket having a fixing portion for the support and a support piece protruding outward from the support is fixed to the upper and lower portions of the support, and the bracket is used for a handrail wall. The present invention relates to a take-out handrail which is formed by bringing a panel out of the nose of a concrete slab and attaching the panel so as to cover the nose of the concrete slab.

  This type of handrail was developed mainly due to architectural design requirements, and because the panel for the handrail wall is located outside the nose of the concrete slab and covers the nose, the nose tip rises. Compared to the general handrails installed directly above, the nose of the concrete slab is not conspicuous in appearance, for example, the handrail that covers the nose of the concrete slab, the handrail that does not even show the handrail props and headboard, the outer wall and the surface It can satisfy various architectural design requirements, such as a continuous handrail.

  However, since the handrail wall panel is a handrail taken out from the nose of the concrete slab, there are the following problems in construction.

  In other words, when a panel for a handrail wall is installed over the nose of a concrete slab, as shown in FIGS. 7A and 7B, a temporary handrail or an external curing unit (single tube assembled in a vertical and horizontal grid pattern) Since the wall connecting 71 connecting the 70 and the like 70 is an obstacle, the handrail support 72 and the headboard 73 are attached in advance, and the retrofit is added to the process of removing the wall connecting 71. Therefore, it is necessary to attach the handrail wall panel 74 to the handrail support 72. Accordingly, the attachment of the panel 74 is a dangerous operation performed without the temporary handrail, the external curing unit 70, etc., and it is desirable that the attachment operation be as simple as possible in order to prevent an accident.

  However, conventionally, as shown in FIGS. 7 and 8, the bolt hole of the bracket 75 attached to the upper and lower portions of the handrail support 72 and the bolt hole of the attachment piece 76 provided on the handrail wall panel 74. Since the bolt 77 is passed through and the nut 78 is fastened and fixed, two workers, a worker holding the panel 74 and a worker passing the bolt 77, are required, and the bracket 75 of the column 72, Since it is necessary to insert the bolts 77 through the three pieces 74 and 76 of the two panels 74 and 74 disposed on both sides of the two panels 74 and 74 at the same time, workability is poor and it is difficult to ensure safety.

  In addition, the take-out handrail described in Patent Document 1 is configured so that a take-out bracket is provided on the panel side, and this take-out bracket is fastened and fixed to the column with bolts and nuts. The two panel take-out brackets are tightened together with bolts, and it is necessary to simultaneously insert the bolts into the support pillar and the take-out brackets on both sides. There is a problem similar to the conventional example.
