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 consist of 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, which are installed almost horizontally between the building walls. A pair of left and right side beams to be erected, a front beam to be erected between each of the above-mentioned supports,
It consists of a large number of joists installed at predetermined intervals between the front beam and the wall of the building, decking material laid on top of these joists, and a cap and fence unit. Some consist of a beam and a handrail fence erected along the side beam. However, in conventional balconies of this type, each support is only connected by a single front beam, so even if both ends of this front beam are firmly connected to each support with connecting materials, the sides of each support It is difficult to completely prevent shaking, 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 in one area when walking, it may cause damage to that part. The deck flexes and shakes up and down, and especially in the central part of the deck, the vertical sway increases due to the flexure of the front beam, which is only connected to each support at both ends. 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. One possible solution to this problem is to increase the cross-sectional area of the columns, side beams, front beams, joists, etc., especially the front beams and joists, but in this case, the material costs will increase and the cost will increase. The problem arises that it is too much.

In view of this problem, the present invention erects each support column so as to be located closer to the building than the front beam, and also constructs a reinforcing beam between each support column, with both ends attached to the wall of the building and the front beam, respectively. By supporting the intermediate part of each joist with the reinforcing beam, the above problems can be solved all at once, and the installation location, especially the depth, can be minimized by keeping the support as close to the building side as possible. To provide a reinforcing structure for a prefabricated balcony, which can increase the area of the balcony, especially its depth.

The cap 8 of the handrail fence 7 located above the front beam 4 is
As shown in FIG. 10, the upper end of each post 2, which also serves as a support for the handrail fence 7, is connected by a bracket 21, and the cap 9 of the handrail fence 7 located above the side beam 3 is connected to the 11th As shown in the figure, it is connected to the wall surface 1 by a bracket 22 and a connecting pipe 23 attached to the wall surface 1 of the building, and furthermore,
The middle part of one cap 8 and the part near the wall 1 of the other cap 9 are formed of square pipes with a rectangular cross section, and are erected on the upper surfaces of the front beam 4 and side beam 3 via auxiliary support supports 25. The upper end of the auxiliary support column 24 is connected to the upper end of the auxiliary support column 24. As shown in FIGS. 1 and 3, the fence units 10 and 11 constituting the handrail fence 7 include an upper chord member 28, a lower chord member 29, and a structure in which the upper chord member 28 and the lower chord member 29 are arranged in the vertical direction. As shown in FIGS. 10 and 11, it is attached to the upper side of each column 2 that also serves as a column for the handrail fence 7, and to the side of the auxiliary column 24. It is attached by connecting both ends of the upper chord member 28 and the lower chord member 29 via a bracket 31. Note that the handrail fence 7 is not limited to this, and may include one in which the cap and the upper chord are integrated and the upper end of the handrail is directly connected to the cap, and the lower chord is connected to the side beam or front beam. It may be integrally formed, or it may be such that the upper chord member and lower chord member are omitted and the balustrade is directly installed between the cap and the side beam or front beam.

Further, in the above embodiment, the auxiliary column support 25 on which the auxiliary column 24 is erected on the upper surface of the front beam 4 has one leg 26a connected to the front wall of the front wall of the front beam 4, as shown in FIG. and the other leg portion 26b that is connected to the upper surface of the joist 5, and is attached to cover the front beam 4 from above. Post 24
A rising piece 27 is formed to be connected to the lower end of the holder. Further, the auxiliary column support 25 for erecting the auxiliary column 24 on the upper surface of the side beam 3 is formed in exactly the same shape as the auxiliary column support 25 attached to the front beam 4.
As shown in FIG. 4, the other leg portion 26b of this auxiliary column support 25 is fixed to the upper surface of a connecting member 15 that connects one end of the side beam 3 to the nailing 14, and the decking material 6 is laid. Since the pillars 2 and auxiliary pillars 24 will get in the way when
However, since these notches are exposed after the decking material 6 is laid, the notches in the decking material 6 are covered by the decking holders 32 attached to each pillar 2 and the auxiliary pillar 24.

In the above embodiment, both ends of the front beam 4 are bent into a rounded shape and installed between the pair of columns 2, so that each column 2 is located closer to the building than the front beam 4. However, the present invention is not limited to this, and each support may be positioned closer to the building than the front beam by connecting a pair of left and right side beams to each support at an intermediate position. Both ends of the front beam 4 of the front beam 4 are bent into a rounded shape to be installed between a pair of pillars 2, but when forming a long balcony, there are cases where the front beam 4 cannot be supported by a pair of pillars 2. In this case, the number of columns 2 can be three or more and the number of front beams 4 can also be two or more. In this case, only one end of the front beam is connected to a pair of columns located on both left and right sides. The pillar may be bent into a rounded shape, and the pillar located in the middle may be positioned in front of the pair of pillars located on both the left and right sides.
In addition, the upper part of each post 2 is also used as a post for the handrail fence 7, but the height of each post 2 is set to the side beam 3 and front beam 4, and the handrail fence 7 is placed on the top surface of these side beams 3 and front beam 4. It is also possible to erect a plurality of auxiliary supports 24 that serve as supports for the vehicle.

As described above, the reinforcing structure of the prefabricated balcony according to the present invention is such that one end or both ends of the front beam connected to a pair of pillars located on both left and right sides are bent in a rounded shape, and each of the pillars is connected to the front beam. The reinforcement beams are erected so as to be located closer to the building than the beams, and a reinforcing beam is erected between each support, and the middle part of each joist, whose ends are attached to the building wall and the front beam, is supported by the reinforcing beam. Therefore, each column is connected by two beams, the front beam and the reinforcement beam, and the connection between each column is extremely strong and can completely prevent each column from rolling. Moreover, since the middle part of each joist, whose ends are attached to the building wall and the front beam, is supported by the reinforcing beam, for example, even if the depth of the balcony increases and long joists are used, It does not sway up and down when walking. Therefore, there is no lateral sway or vertical sway when walking, which causes a sense of uneasiness. It can be made larger, resulting in huge savings in material costs.

In addition, even if the depth of the balcony is increased, the distance between each pillar and the wall of the building does not become very large, and when the pillars are installed on a terrace, the depth of the terrace is limited even if the depth of this terrace is relatively small. In addition to being able to design deep balconies without being overly crowded, each pillar is positioned closer to the building side, so each pillar is less likely to narrow or obstruct the view from the windows on the floor below. It is something.

Moreover, in the above embodiment, one end or both ends of the front beam connected to the pair of columns located on both the left and right sides are bent in a rounded shape, so that the ends of the front beam are butted against each column. In addition, the front end of each side beam and both ends of the front beam can be connected by a connecting material, and there is no need for a means to connect the front end of each side beam and both ends of the front beam. Since it is bent into a radius, there is no need for connecting means or fixing means at the corners of the handrail fence, and the number of parts required for these connecting means, connecting means or fixing means increases significantly. It is easy to install, inexpensive, and has a strong structure.
