[Embodiment] Fig. 1 is a sectional view showing a balcony floor to which one embodiment of the present invention is applied, Fig. 2 is a schematic diagram showing a floor beam and a mounting engagement piece, and Fig. 3 is another embodiment of the present invention. A schematic diagram showing the
is a schematic diagram showing a conventional example.

FIG. 1 shows a plurality of lower floor building units 101 arranged horizontally adjacent to each other, and some of the lower floor building units 1
In a unit building configured by mounting an upper floor building unit 102 on the upper part of a building 01, a balcony floor 103 is provided above the lower floor building unit 101 on which the upper floor building unit 102 is not mounted.

In FIG. 1, 101A is the ceiling beam of the lower floor building unit 101, and 102A is the floor beam of the upper floor building unit 102.

Here, the balcony floor 103 has a balcony floor frame 10 bolted to the ceiling girder 101A of the lower floor building unit 101. The balcony floor frame 10 is constructed by spanning a steel pipe floor beam 12 having a slope from one floor beam 11 to the other floor beam 11 between opposing section steel floor beams 11.

At this time, as shown in FIG. 2, each of the floor beams 12 engages the top surfaces of the upper and lower webs of the corresponding floor beams 11 at both ends thereof, and the floor beams 12 have a predetermined slope. Attachment engagement pieces 13A and 13B that can be attached are welded.

Each of the attachment and engagement pieces 13A and 13B has upper and lower webs that engage with the upper surfaces of the upper and lower webs of the floor girder 11, respectively. Then, the upper surface of the upper web of the mounting engagement piece 13A is welded to a position H1 lower than the upper surface of the floor beam 12, and the upper surface of the upper web of the mounting engagement piece 13B is H2 lower than the upper surface of the floor beam 12 (H1>H2). By welding at a lower position, a predetermined slope is given to the floor beam 12.

A spacer 14 is provided between the balcony floor frame 10 and the ceiling girder 101A of the lower floor building unit 101.
through the lower web of the floor girder 11 and each mounting engagement piece 13
The lower webs of A and 13B are jointly fastened to the ceiling girder 101A of the lower floor building unit 101 with bolts 15.

Furthermore, the balcony floor 3 has a floor joist 16 fixed to the upper part of the floor beam 12 of the balcony floor frame 10.
Further, a floor material 17 is laid on top of the floor joists 16.

According to the above embodiment, the following effects (1) to (4) are obtained.

[0031] The mounting engagement pieces 13A and 13B provided at both ends of the floor beam 12 can engage the corresponding floor beam 11 in the vertical direction, and can impart a predetermined slope to the floor beam 12. It is configured as follows. Therefore, the mounting engagement pieces 13A and 13B provided at both ends of the floor beam 12 are placed on the top surfaces of the upper and lower webs of the corresponding floor beam 11 and engaged with the floor beam by welding, bolts, etc. It will be attached to the girder 11. Thereby, both ends of the floor beams 12 can be easily, quickly, and accurately positioned and fixed at appropriate mounting height positions with respect to the corresponding floor beams 11.

■ Separate attachment engagement piece 1 at the end of the floor beam 12
3A and 13B, each of the ends of the floor beam 12 can be placed at an appropriate position in the vertical direction with respect to the corresponding floor beam 11 without complicating the end shape of the floor beam 12 itself. Can be installed securely.

■Since the attachment engagement pieces 13A and 13B joined to the ends of the floor beam 12 are fastened together with the floor beam 11 to the ceiling beam 101A of the lower floor building unit 101, the floor beam 11 and the floor beam The floor frame 10 composed of the beams 12 can be firmly attached to the ceiling girder 101A of the lower floor building unit 101.

(2) A desired water gradient can be provided to the balcony floor 103 reliably and easily.

The embodiment shown in FIG. 3 differs from the embodiments shown in FIGS. 1 and 2 in that the lower ends of the inverted L-shaped mounting engagement pieces 21A and 21B are
The reason is that it is made to match the lower surface of the floor beam 12.

According to this, the mounting engagement pieces 21A, 21B
Since the lower end of the floor beam 12 is aligned with the lower surface of the floor beam 12, when joining the mounting engagement pieces 21A and 21B to the end of the floor beam 12, the bottom surface of the floor beam 12 and the attachment piece are placed on the workshop floor. The joining pieces 21A and 21B can be reliably and easily joined by placing the lower ends thereof.

[0037] In carrying out the present invention, the attachment engagement portions to the floor girder provided at both ends of the floor girder do not necessarily have to be made of a separate member from the floor girder, but may be formed by processing the floor girder itself. It may also be provided by doing so.
