Description

[Detailed Description of the Invention] The present invention relates to a prefabricated balcony, in particular, a sectional balcony that is formed between the pillars and the wall of a building by erecting pillars on the ground or on a concrete foundation or terrace provided on the ground. Regarding sectional balconies.

Conventional balconies of this type have a plurality of pillars erected at predetermined intervals from the building, and a pair of pillars located on both the left and right sides of these pillars, and a nearly horizontal space between them and the wall of the building. A pair of left and right side beams are installed in the building, a front beam is installed between each of the above-mentioned supports, a large number of joists are installed at a predetermined interval between the front beam and the wall of the building, and these Some railings consist of decking material laid on the top surface of the joists, and a handrail fence constructed of a cap and a fence unit and erected along the side beams and front beams. However, in conventional balconies of this type,
Since the top of each pillar doubles as a support for the handrail fence and is located at the corner of the balcony, it is not possible to increase the depth of the balcony unless there is a large gap between each pillar and the building. In order to stand on a terrace, it is not possible to construct a deep balcony unless the area of the terrace, especially its depth, is increased, and the depth of the balcony is limited by the depth of the terrace. Even if it is possible to secure the depth of the balcony by erecting each pillar at a certain distance from the building using the ground or a concrete foundation or terrace built on this ground, it is not possible to maintain the distance between each pillar and the building. If they are made too large, these pillars will come within the field of view from the windows on the lower floor, obstructing the view, and giving the impression of being extremely intrusive.

Therefore, in this type of balcony, it may be possible to position each support column closer to the building than the front beam, and connect the pair of left and right side beams to each support column at an intermediate position, but in such a case, each side beam In addition to means for firmly connecting each pillar, means for connecting the front end of each side beam and both ends of the front beam, and handrails erected along each side beam and front beam. A means for firmly connecting and fixing the corners of the fence is required, which makes the installation extremely complicated, and the number of parts required for connecting, connecting, or fixing increases significantly, which increases costs. The problem arises that the amount increases.

In view of this, the present invention allows the pillars supporting the balcony to be placed as close as possible to the building side to minimize the installation location, especially the depth, and at the same time, the area of the balcony, especially the depth, can be made relatively large. As a result, even if the depth of the balcony is increased, the pillars will not obstruct the view, and the installation work will be complicated due to the need for special means for joining or fixing. To provide a prefabricated balcony which is strong and can be manufactured at low cost without causing a significant increase in the number of parts.

Hereinafter, the present invention will be described in detail based on embodiments shown in the accompanying drawings.
