Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a balcony foundation structure.

Traditionally, a veranda has been built above the roof of the lower building on the first floor, allowing entry and exit through an opening in the outer wall of the second floor, but from the viewpoint of strength,
The disadvantage was that the veranda could not be extended to the outside of the roof of the lower house, and the walking range was narrow.
Therefore, a proposal was made to extend part of the veranda outward from the roof of the lower house and support the overhang with pillars, but in that case, the pillars would spoil the aesthetics of the building and would also be complicated to construct. There was a new problem:

Therefore, an object of the present invention is to provide a veranda base structure that allows a part of the veranda to be formed to extend outward from the roof body while maintaining sufficient strength and is also aesthetically pleasing.

An embodiment of the present invention will be described with reference to FIGS. 1 to 8. In other words, as shown in Fig. 1, this veranda base structure is constructed from an opening provided in the outer wall of the second floor to the upper part of the lower roof of the first floor single-story building 2 formed on the outdoor side of the two-story building main body 1. This is applied when constructing a balcony 3 that allows access.
As shown in Fig. 2, in the first floor part one-story building 2,
Side end surface 4 of roof panel 4' constituting roof main body 4
To the protruding corner portion 5 formed by the front end surface 4b and the front end surface 4b,
One corner of the cross beam 8 consisting of the vertical beam 6 and the cross beam 7 is fixed, and the side beam 9 is arranged parallel to the outside of the roof panel side end surface 4a and orthogonally connected to the tip of the cross beam 7 of the cross beam 8. , the front beam 10 is connected to the front end surface 4 of the roof main body
b, and is orthogonally connected to the tip of the longitudinal beam 6 of the cross beam 8, and the end of the front beam 10 is orthogonally connected to the front end of the side beam 9. Note that the rear end of the side beam 9 is connected to a girder 11 of the building main body 1. In FIG. 2, 12 is an outer wall panel.

This will be explained in detail below. FIG. 3a is a plan view showing the underlying structure of the balcony corner, FIG. 3b is a front view thereof, and FIG. 3c is a sectional view of FIG. 3a viewed from the left. First, as shown in FIGS. 4 and 5, the cross beam 8 is made by welding a pair of groove-shaped horizontal beams 7a and 7b orthogonally arranged on both sides of the center of the groove-shaped longitudinal beam 6, and then welding the upper and lower surfaces of the joints. are sandwiched between the connecting plates 13 and welded in the same manner. In FIG. 5, 14 is an end plate, 15 is a bolt insertion hole for connecting metal fittings, and 16 is an end plate.
17 is a roof connection bolt insertion hole, and 17 is a spacer welded to the lower surface of the vertical beam 6.

One end of the cross beam 7a (the part surrounded by the imaginary line A in Figure 4)
As shown in FIG.
A spacer 20 with a wall connection bolt insertion hole is welded to the lower surface, a roof connection bolt insertion hole 21 is provided in the web of the cross beam 7a, and a joint beam connection bolt insertion hole 2 is provided in the reinforcing plate 19.
Drill 2. One end of the vertical beam 6 (the part surrounded by the imaginary line B in FIG. 4) is constructed in the same manner.

The other end of the cross beam 7b (the part surrounded by the imaginary line C in Figure 4)
As shown in FIG. 7, an end plate 23 is welded to the end, and side beam connecting bolt insertion holes 24 are bored in the end plate 23.

The other end of the vertical beam 6 (the part surrounded by the imaginary line D in Figure 4)
As shown in FIG. 8, an end plate 25 is welded to the end and a front beam connecting bolt insertion hole 26 is bored. Note that a balcony floor support fitting 27 is welded to the web of the vertical beam 6.

As shown in FIG. 3, the cross beam 8 configured in this way is attached to the upper end surface of the wall panel 12 with one corner of the vertical beam 6 and the horizontal beam 7a aligned with the protruding corner of the roof panel 4'. and fixed to the panel frame 4c of the roof panel 4' and the panel frame 12a of the wall panel 12 with bolts 28. In this case, the center portion of the cross beam 8 is bolted to the upper piece of the wall panel connection fitting 29 shown in FIG. 3b.

Next, a horizontal joint beam 30 made of lip channel steel is installed.
is placed parallel to the horizontal beam 7b, and its one end is fixed to one end of the vertical beam 6 with a bolt 31. Another vertical joint beam 32 is placed parallel to the vertical beam 6, and its one end is fixed to the horizontal beam 6 with a bolt 33. Fix it to one end of 7a. That is, the horizontal joint beam 30 is fixed to the side end surface 4a of the roof panel 4' via the longitudinal beam 6, and the vertical joint beam 32 is fixed to the front end surface 4b of the roof panel 4' via the horizontal beam 7a.

Thereafter, a side beam 9 made of ripped channel steel is arranged parallel to the vertical beam 6 and fixed to the other end of the horizontal joint beam 30 and the other end of the horizontal beam 7b with bolts 34.

Next, the front beam 10 made of lip channel steel is
It is arranged parallel to the horizontal beam 7a and fixed to the front ends of the vertical joint beam 32, the vertical beam 6, and the side beam 9 with bolts 35, respectively.

A balcony floor (not shown) is laid on top of the balcony base material thus formed, and a balcony wall is further erected to construct a balcony.

In this way, the cross beam 8, the horizontal joint beam 30, the vertical joint beam 32, the side beams 9, and the front beam 10 can form the base of the balcony that extends outward from the roof panel 4', so that the walking range of the balcony can be improved. can be expanded. Moreover, since the cross beams 8 support the side beams 9 and the front beams 10, the strength is strong. Furthermore, since pillars are not used to support the veranda overhang, it is both aesthetically pleasing and easy to construct. Furthermore, the veranda overhang also functions as an eaves for the first floor portion of the one-story building 2.

As described above, the balcony base structure of the present invention is a balcony base structure formed on the upper part of the lower roof of a partial one-story building, and is comprised of a roof panel having a panel frame on the outer periphery. A roof main body, a cross beam in which one corner of the vertical beam and the horizontal beam connected in a cross shape is fixed to an out corner formed by the side end face and front end face of the roof main body, and the end face on the side of the roof main body. a side beam arranged parallel to the outside of the cross beam and orthogonally connected to the tip of the cross beam; A front beam connected orthogonally to the front end of the side beam, a horizontal joint beam arranged parallel to the side beam, one end fixed to the side end surface of the roof body and the other end fixed to the side beam, and one end arranged parallel to the vertical beam. is fixed to the front end surface of the roof body, and the other end is fixed to the front beam, and a part of the blunder can be moved to the outside of the roof body while maintaining sufficient strength. It has the effect of being able to be formed into an overhang and having an excellent aesthetic appearance.
