2. Description of the Related Art Japanese Patent Application Laid-Open No. 9-279763 discloses that
Architectural assembly panels that can be easily manufactured at low cost and with high strength without the use of special production lines, can be manufactured at low cost and have high strength, and can flexibly respond to changes in specifications of interior and exterior materials. It can be used as a structural framework of the upper part, and even if the steel frame on the top floor is omitted, it can sufficiently resist wind loads, etc. In addition, since the weight of the top floor does not increase, the steel frame section of the steel frame on the lower floor part There has been proposed a multi-story building in which it is not necessary to increase the size and the amount of steel used can be reduced.

[0003] The multi-story building proposed in the above publication is a three-story building, and an assembly panel with braces is used as a construction panel for a roof part on the third floor and walls on all floors including the third floor. I have. As shown in FIG. 23, the through member 30 is used for bolt connection between the lower end portion of the assembled panel 17 of the panel type structural floor 39A corresponding to the third floor and the steel frame type structural floor 39B corresponding to the first and second floors. The pass-through member 30 is made of a channel steel, and the web 30a is arranged vertically toward the outside of the building along the width direction of the assembly panel 17. Through material 3
The opening between the upper flange 30b and the lower flange 30c is open toward the inside of the building. Through material 30
The outer end of a fitting 34 made of T-shaped steel is welded to the inner surface of the web 30a, and the inner end of the fitting 34 is a large beam 2 made of H-shaped steel of a steel structure floor 39B.
9 is mounted on the upper flange 29 b and is bolted by a high-strength bolt 35.

[0004] The upper flange 30b of the thread member 30 faces the connecting member 21 with a nut fixed in the lower horizontal frame member 2 of the assembly panel 17 of the panel-type structural floor 39A. Spacer 33 is inserted. The lower flange 30c of the threading member 30 faces the connecting metal fitting 21 with a nut fixed in the upper horizontal frame member 2 of the assembly panel 17 of the steel structure floor 39B, and a spacer 37 is inserted between the connecting member 21 and the web 21a.

[0005]

In the conventional multi-story building constructed as described above, the deck plate 4 is used to cast the floor slab concrete of the panel-type structural floor 39A.
When attaching 1 to the upper flange 29a of the girder 29,
Since the deck plate 41 and the metal fitting 34 interfere with each other, and the deck plate 41 and the high-strength bolt 35 interfere with each other,
Complicated work such as providing a notch 41a for avoiding interference in the deck plate 41 occurs. Further, since the metal fittings 42 for the formwork of the deck plate 41 and the metal fittings 34 interfere with each other, it is necessary to provide a notch 42a for avoiding interference in the metalwork 42 for the formwork. There was a problem. Furthermore, these deck plates 41
There is also a problem that the concrete leaks from the notch 41a of the metal mold, the notch of the metal fitting for formwork 42, and the gap between the through holes for the bolts of the metal fitting 34.

As described above, the upper flange 3 of the thread member 30
Since the spacer 33 is inserted between the connection fitting 21b and the connection fitting 21 with the nut of the assembly panel 17 of the panel-type structural floor 39A, a gap remains, and there is also a problem that rain enters from the gap. When the level in the height direction of the girder 29 of the steel structure floor 39B is determined, the joint hardware 3
4. The level of the horizontal member 2 of the thread member 30 and the assembly panel 17 is determined, and the top end of the horizontal member 2 is at the floor level, so that the floor slab 43 becomes thicker than necessary, which is uneconomical. However, there is a problem that a complicated design is performed. Furthermore, in the actual construction, the level and horizontal position of the girder 29 in the height direction and the horizontal position change from the design values in accordance with the construction accuracy. Is displaced, and this error cannot be absorbed.

Accordingly, an object of the present invention is to make it easier to mount a deck plate and a metal formwork, to eliminate concrete leakage at the time of casting, and to make the thickness of the floor slab economical in proportion to the load bearing capacity. A joint structure between a panel-type structural floor and a steel frame-type structural floor in a multi-story building that can be freely set, accurately absorbs the difference between the level in the height direction of the girders and the horizontal position, and accurately prevents rain from entering. It is to provide.
