Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a prefabricated balcony installed on the wall of a building, and in particular, supports are erected on the ground or on a concrete foundation, terrace, roof, etc. provided on the ground. This invention relates to a reinforcing structure for a prefabricated balcony that is formed between the balcony and the wall.

Traditionally, this type of balcony consists of a pair of both-side supports that are erected on both the left and right sides at a predetermined distance from the building, and a pair of left and right sides that are installed approximately horizontally between these both-side supports and the wall of the building. A beam, a front beam installed between each of the pillars, a number of joists installed at predetermined intervals between the front beam and the wall of the building, and a deck installed on the top surface of these joists. There is a type of handrail fence that is constructed of wood, a cap and a fence unit, and is erected along the side beams and front beam.

However, in conventional balconies of this type, each support is connected by a single front beam, so even if both ends of this front beam are firmly connected to each support, horizontal sway of each support is completely prevented. It is difficult to do so, and since the joists installed between the front beam and the wall of the building are only fixed at both ends, if the load is concentrated on a part when walking, that part will bend and move up and down. Shaking, especially in the central part of the deck of a long balcony, the vertical sway increases due to the deflection of the front beam, which is only connected to each support at both ends, and when walking, it causes sideways sway and vertical sway. There is a problem in that swaying occurs, giving a sense of unease, and this problem becomes especially noticeable when the depth of the balcony is increased. Some methods of solving this problem include increasing the cross-sectional area of columns, side beams, joists, etc., or installing reinforcing beams between each column, but the former increases material costs and costs. ,
The latter has the disadvantage that, especially on long balconies, the central part of the deck installed between the pillars is still weak.

Therefore, the present invention provides a pair of both-side support pillars that are installed on both the left and right sides at a predetermined distance from the building;
An intermediate support erected approximately in the middle between the support supports on both sides, a pair of left and right side beams installed approximately horizontally between the support support on both sides and the wall of the building, and a pair of side beams at the same height as these side beams. A front beam is installed substantially horizontally between the both side supports and extends in a direction away from the building from the position of the both side support supports, and a predetermined distance is maintained between the front beam and the wall surface of the building. A prefabricated type structure consisting of a plurality of joists, which are constructed with a plurality of joists, a decking section formed by laying decking material on the upper surface of these joists, and a handrail fence erected along the pair of side beams and the front beam. In the balcony, the above-mentioned both side supports and the intermediate support are erected so as to be located closer to the building than the front beam, and a reinforcing beam is installed between the pair of above-mentioned both side supports and the middle support, so that both sides are connected to the wall of the building, respectively. A substantially intermediate portion of each of the joists attached to the front beam and the front beam is supported by the reinforcing beam, and a portion above the intermediate support of the plurality of joists installed between the front beam and the wall surface of the building is supported by the reinforcing beam. By providing a reinforcing structure for a prefabricated balcony in which the located joists are fixed to the upper end of the intermediate support, the purpose is to reinforce the central part of the weakest deck part and obtain a robust prefabricated balcony.
