Description

  The present invention relates to a handrail attached to a staircase, a veranda, a fence, a slope, a corridor, and the like, and more particularly, to a handrail in a mode in which a panel is attached between columns and a construction method thereof.

Due to the diversification of the building exterior, some are used as a fence for balconies and stair railings. As an example of the construction procedure, a frame that frames the upper, lower, left, and right frames is attached via brackets that are taken out from the columns. After that, it was constructed by inserting a panel into the frame.

  In the case of the handrail described above, when the panel is fitted into the frame, the panel is inserted into the panel insertion groove of the upper frame of the frame from below and attached in a blunt manner. In recent years, handrails that take the appearance design into account have been demanded, and among them, there are some that have the visual effect of making the panel continuous by making the vertical frame finding width as narrow as possible. However, when such a handrail is installed, since the vertical width of the vertical frame at the take-out position is narrower than the vertical width of the handrail column, the interval between the vertical frames becomes wider than the interval between the columns. For this reason, if the panel is to be attached from the side of the scaffold, it must be inserted in a state where the panel is tilted back and forth so as to avoid the support. In such a situation, it is not easy to attach the panel. On the veranda railings of houses, there were cases in which a work vehicle or a gondola was used, so there was a serious problem affecting construction cost and construction period.

  The present invention has been made in view of the above-described problems, and it is an object of the present invention to provide a handrail construction method and handrail capable of safely and easily performing construction even when appearance design is prioritized.

The present invention includes a support column, a lower frame, a vertical frame, a panel unit, and a headboard, and the support column has an upper bracket for attaching the headboard to the upper portion, and a side portion on the outer finding surface. It has a bracket and a lower bracket on the lower side of the side bracket, a vertical frame having a panel insertion groove extending in the frame longitudinal direction is fixed to the side bracket, and the frame length is fixed to the lower bracket A lower frame having a panel insertion groove extending in the direction is fixed to form a frame body whose upper side is open, and the frame is attached to the inner peripheral side of the panel in a form held by each panel insertion groove. Yes, the headboard has a panel insertion groove continuous in the longitudinal direction. The upper edge of the panel is inserted into the panel insertion groove of the headboard, and the headboard is fixed to the upper bracket of the column. Also hold by the four rounds of the panel And a, coping, rather than panels swallow groove opened and closed at a position inside, characterized in that it opens the upper position of the frame in a state of being fixed to the upper bracket.

According to the present invention, the both sides of the vertical frame having the panel insertion groove and the lower frame are framed in three directions with the panel insertion groove continuous to the inner peripheral side, and the panel is inserted from the upper side of the opened three-side frame body. By doing so, the panel can be easily and safely attached to the frame regardless of the vertical frame finding width. Furthermore, since the headboard opens and closes at the upper position of the frame body, the panel can be inserted into the frame body from above by opening and closing a part of the headboard with the headboard attached to the support column, so that the construction efficiency is improved.
