Abstract

PURPOSE:To facilitate the construction of a handrail at a construction site so as to reduce construction time and uniform a gap between adjacent panels. CONSTITUTION:There are provided a surface panel 21, a back face panel 22, an upper furring strip 23 fixedly clamped across both end parts of the upper edges of the opposed face parts 21a, 22a of the panels 21, 22, and a lower furring strip 24 clamped between the lower part of the surface panel 21 and the opposed face part retreated inward by the specified measure from both end parts of the lower edge of the back face panel 22. The surface panel 21, back face panel 22, upper furring strip 23 and lower frame edge 24 are unitized into a handrail panel 20, and plural handrail panels 20 are previously prepared. A handrail construction part is provided with plural column bodies 15, 15... fixedly erected at approximately same width spaces as the width of the lower furring strip 24. The unitized handrail 20 is inserted from above into a space part K formed by the adjacent column bodies 15, 15, and then the upper frame edge 23 and the upper end part of each column body 15 are fixed to each other by a fixing means.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a handrail used for, for example, a balcony having a ceiling surface of a lower floor of a unit house as a floor surface.

[0002]

2. Description of the Related Art Conventionally, there is one in which a balcony is provided in a house unit on the lower floor. Further, such a balcony is provided with, for example, a frame type handrail as shown in JP-A-61-120931 and a panel-type handrail as shown in JP-A-61-204437.

As a panel type handrail, a plurality of beams are assembled in a grid pattern to form a floor frame, a plurality of pillars are erected and fixed on the floor frame, and then an upper furring strip is attached to an upper end of the pillar. The front panel and the back panel having a rectangular shape are fixed to the pillar and the upper furring strip by fixing means such as bolts.

[0004]

By the way, in the handrail construction method constructed as described above, since the handrail and the handrail panel are assembled at the site where the balcony is constructed, it is very troublesome. It was In addition, the positioning of the front panel and the back panel is troublesome, and the gap between adjacent panels tends to vary.

In view of the above situation, the present invention can facilitate the construction of the handrail at the construction site, can shorten the construction time, and can even out the gaps between the adjacent panels. The purpose of the present invention is to provide a construction method for handrails that can be used.

[0006]

In order to achieve the object, a first aspect of the present invention is to provide a front panel formed in a rectangle and a back surface formed in a rectangle shorter in the height direction than the front panel. A panel, an upper furring strip that is clamped and fixed over both edges of the upper surface of the facing surface portion between the front panel and the back panel, and a predetermined dimension that is lower than both edges of the front panel and lower edges of the back panel. A plurality of handrail panels unitized by the lower furring strips sandwiched between the front panel and the back panel at the position retracted inward are prepared in advance, and the handrail construction portion is wider than the lateral width of the lower furring strips. After fixing a plurality of pillars forming a wide space portion upright and inserting the unitized handrail panel from above toward the space portion, the handrail panel and the pillar body are fixed by fixing means. That And butterflies.

A second gist is a front panel and a back panel having a rectangular shape, an upper furring strip clamped and fixed to an upper end of a facing surface portion of each panel, and a lower furring strip held below a facing surface portion of each panel. A handrail panel is configured by and the handrail panel is inserted from above into a space formed by a plurality of pillars standing upright at a predetermined interval in the handrail construction portion, the upper furring strip and the pillar Head and the lower furring strip and a supporting member fixed to the column body are fixed by a fixing means, and the handrail panel is provided in either the lower furring strip or the supporting member in the space. A guide portion is formed to maintain a relative relationship with the lower furring strip or the other of the support members when the guide portion is inserted into the portion from above.

[0008]

According to the present invention, since the handrail panel is unitized, the handrail can be easily installed at the construction site, and the guide portion ensures the insertion of the handrail panel into the space.
