[0002]

2. Description of the Related Art Conventionally, a unit-type building or the like that can be constructed in a short period by joining a plurality of building units manufactured in a factory in advance at a construction site has been used.
In a unit type building, various units are prepared for building various types of buildings such as Japanese style and Western style houses, and if you use the Balconi unit which is a building unit for Balconi It can be equipped with a balcony. FIG. 18 and FIG. 19 show a four-point supporting balcony 1A as an example of the balcony provided in the unit type house. The four-point supporting balcony 1A is formed by connecting the balcony units 2 and 3, and the corners at both ends are projecting corners 4. The balcony units 2 and 3 are joined at their base ends to each of the two building units 5 and 6 arranged on the second floor of the unit-type house, and the tip ends are supported by the pillars 7, whereby the four points are connected. Support Balconi 1A has four corners supported. Each of the balcony units 2 and 3 has a floor portion 10 forming a floor of the balcony 1A, and this floor portion.
A handrail wall 20 is provided along the edge of 10.

The floor portion 10 is a floor frame made of grooved steel or the like having a U-shaped cross section which is joined to the frame of the building units 5 and 6.
11 and joist 12 laid between this floor frame 11,
The deck plate (13) is placed on the joists (12). The handrail wall 20 includes a handrail base frame 21 erected on the floor frame 11, an outer wall material 22 attached to the outdoor side of the handrail base frame 21, and a base surface attached to the indoor side of the handrail base frame 21. And the material 23.
On the upper surface of the handrail wall 20, a cover member 24 is covered, and columns 26 for supporting the handrail member 25 are provided upright. The handrail base frame 21 built in the handrail wall 20 is a substantially ladder in which a vertical member 21A made of grooved steel having a U-shaped cross section and a horizontal member 21B made of grooved steel having a U-shaped cross-section are joined together. It is a shape. The surface of the deck plate 13 and the side surface of the handrail wall 20 on the indoor side are covered with a waterproof sheet 14. By preparing various kinds of such balcony units, various types of balcony can be formed.

On the other hand, as the types of balcony units increase, the types of parts that make up the handrail base frame also increase,
The manufacturing of the handrail base frame becomes complicated. Therefore, the applicant of the present application sets a minimum unit (hereinafter, referred to as “module”) that is a reference of the length of the building unit, and as shown in FIG. 20, a frame configuration having a length dimension corresponding to the module. A straight joint for joining the body 31 and the frame constituting body 31 to each other and having a substantially I-shaped planar shape
32 and a corner joint 33 having a substantially L-shaped plan
We have proposed a unitized handrail base frame composed of and (Japanese Patent Application No. 6-233027). Each of the frame structure 31, the corner joint 32, and the straight joint 33 is provided with a mounting portion 34 for fixing the columns at intervals corresponding to the above-mentioned module along the edge of the balcony, and these mounting portions 34 are provided. According to such a unitized handrail base frame in which the handrail members are arranged to be bridged over the top of the fixed column, a wide variety can be obtained by combining the frame structure body 31, the corner joint 32 and the straight joint 33. A new balcony wall is formed to reduce the number of parts.

By the way, as shown in FIG. 20, in a balcony installed in a building, not only the four-point supporting balcony 1A having a long projecting dimension from the outer wall 8 of the building but also a short projecting dimension from the outer wall 8 of the building. The cantilever balconi 1B (shown by the two-dot broken line in the figure) is also available as a balconi unit. By connecting such a cantilever balconi 1B to the four-point supporting balconi 1A, we would like to form a more versatile balconi. There is a request. However, Canchibalconi 1B
When trying to connect different types of balconies, such as connecting the four-point support balconies 1A, the corner portions 9 are formed in the handrail wall of the balconies. Among the handrail walls forming the entry corner portion 9, the handrail wall 9A along the vertical direction in the figure has its position deviated from the center corresponding to the module to the four-point supporting balcony 1A side. Balconi 1B side mounting part 34
However, if the position is not shifted from the position a corresponding to the module to the position b, a discomfort in appearance occurs in the arrangement of the columns. Therefore, the four-point support balcony 1A that is connected to the cantilever balcony 1B requires a dedicated handrail foundation frame with a different mounting portion 34 position from the unitized handrail foundation frame, and the number of parts is sufficiently reduced. There is a problem that it can not be planned. Further, there is a demand for shifting the position of the mounting portion 34A near the outer wall 8 from the position C corresponding to the module to the position D in order to facilitate the mounting work of the handrail member and the column.

An object of the present invention is to provide a handrail base frame for a balcony that can sufficiently reduce the number of parts even if different types of balcony are connected.

And an auxiliary structure provided with a mounting portion for connecting the basic structure and the auxiliary structure to each other.
It is characterized by having a length dimension corresponding to the law .
Or Te smell, before Symbol basic construct, given the length dimension to form a plurality of frame configuration, corner joints and the planar shape of a substantially L-shaped planar shape interconnecting these frame configuration Can include a substantially I-shaped straight joint. Further, as the balcony, a four-point support balcony unit in which a projecting dimension from a wall surface is a dimension corresponding to a reference dimension of the building unit and four corners thereof are supported, and a projecting dimension from the wall surface is the building unit. A cantilevered balconi unit whose dimensions do not reach the standard dimensions can be used, and when connecting different types of balconies, the basic configurations of the four-point support balconi and the cantilevered balconi can be used. It is desirable to construct the auxiliary structure by including a corner joint connecting the bodies to each other.
Further, as the auxiliary structure, at least the building-side end of the handrail wall arranged on both side edges of the balcony is formed, and the position of the mounting portion is from the position corresponding to the same reference dimension to the outdoor side. It is also possible to use the ones that are out of alignment.

[0008]

In the present invention as described above, as the basic structure, only the required types of those having the length dimension corresponding to the reference dimension of the building unit are prepared, for example, a plurality of plural units formed in a predetermined length dimension are prepared. If a frame joint body, a corner joint for connecting these frame body bodies to each other in a plane shape of a substantially L shape, and a straight joint having a plane shape of a substantially I shape are prepared, they are extended in a straight line by a combination thereof. Since various things such as handrail base frame, bent handrail base frame with protruding and entering corners, etc. can be manufactured, it is easy to support various types of balcony, and the parts that make up the handrail base frame are Is standardized,
It is possible to reduce the number of parts. Also, when different types of balconies are connected, the handrail wall of the balconies has an entry corner, and if the mounting part needs to be displaced from the position corresponding to the module, the mounting position is different from the basic structure. If the frame of the handrail wall at the corner portion is formed to include the displaced auxiliary structure, it is possible to shift the position of the mounting portion to a position that does not cause a discomfort in appearance in the arrangement of the columns. Moreover, the auxiliary structure is only the position of the basic structure and the mounting portion are different, the basic structure is as it can substantially the same as the basic structure, it is possible to divert a part of the basic structure. Therefore, even if the auxiliary structure is adopted, the number of parts does not increase significantly, and when used in combination with the basic structure, it is significantly larger than when a dedicated handrail base frame for connecting different types of balcony is used. Moreover, it is possible to reduce the number of parts, and thereby the above-mentioned object is achieved.

Since the components constituting the handrail base frame are made common, the number of components can be reduced.

Further, since different types of balconies, such as the four-point supporting balconies 1A and the cantilever balconies 1B, are connected, the handrail wall of the balconi is formed with the entry corner 9 and the mounting portion.
Even if it is necessary to shift the position of 34 from the position corresponding to the module, if the auxiliary corner frame 42 is used, the position of the mounting part 34 will be in a position that does not cause discomfort in appearance in the arrangement of the columns. Can be shifted and the appearance of the building can be improved.

Further, the frame 42 for the entering corner has a basic structure except that the positions of the frame component 31 and the joints 32, 33 and the mounting portion 34 are different.
It is possible to make it almost the same as 2, 33, but it is possible to divert parts such as the frame structure 31 and the number of parts is greatly reduced compared to the case where a dedicated handrail base frame for connecting with different types of balcony is adopted. Can be reduced.

Further, the members that are divided into the two balcony units such as the straight joint 32, the corner joint 33, and the frame 42 for entering corners are joined by the connecting plate having an L-shaped cross section, so that they are joined at the factory. This makes it easier to join the manufactured balcony units at a construction site and increases the strength against vertical loads.

Further, since the position of the mounting portion 34 deviates from the position corresponding to the module and the frame 41 for the wall is provided so as to be away from the wall of the building, the work space near the wall is expanded, and at the construction site. The handrail can be easily bridged over multiple columns.

Although the present invention has been described with reference to the preferred embodiment, the present invention is not limited to this embodiment, and various improvements and design changes can be made without departing from the gist of the present invention. It is possible. For example, the members constituting the frame structure, the straight joints, and the corner joints are not limited to square tubular steel pipes, channel members, and angle members, but other members such as H-shaped steel and cylindrical steel pipes may be used. It may be used, and constituent members such as a frame constituent member can be appropriately set in practice.

Further, the gable frame components 44 and 46 and the girder frame component 45 as the auxiliary components shown in the above embodiment may be omitted. In this case, the wife frame structure
44, 46 and girder frame structure 45 equivalent,
The frame structure 31 and the joints 32 and 33 may be formed in combination.

[0032]

As described above, according to the present invention, even if different types of balcony are connected, by providing an auxiliary structure having the same structure as the basic structure, a dedicated handrail base frame is manufactured. Since it is not necessary, the number of parts can be reduced.
