Further, a projecting beam 17 supported by a projecting corridor pillar 16 and an end beam 18 supported between the projecting corridor pillars 16 and 16 are provided at the end of the corridor 2b of the building 1b to project the corridor frame 10. Is done. The buildings 1a and 1b are arranged so that the corridors 2a and 2b are close to each other at the projecting ends. On the other hand, the connecting plate 3 is formed by stretching the floor material 20 in the frame body 19. The floor material 20 connects the frame body 19 to the frameworks 10 of the corridors 2a and 2b.
It is preferable that it is stretched after connecting to 10. The frame body 19 constituting the connecting plate 3 is formed in a rectangular frame shape in a plan view, and the cross-sectional shape of each part of the frame body 19 is a U-shape.
As shown in FIG. 3, bolts 26 are provided on the lower surfaces of the lower pieces 21 on both sides by welding or the like so as to project downward. This frame 19 is used to frame the corridors 2a and 2b of each building 1a and 1b.
In connecting 0, first of all, as shown in FIG. 1, the corridor front beam 14 at the end of the frame 10 of one corridor 2a and the end beam 18 at the end of the frame 10 of the other corridor 2b are connected. The receiving members 23, 23 are fixed to the outer surfaces by welding or the like. Each of the receiving members 23 is formed in a horizontal L-shaped cross section by a shape steel or the like, and a large diameter hole 22 is bored in an upper piece 24 thereof. Then, as shown in FIG. 1, the frame body 19 constituting the connecting plate 3 is laid over both the receiving members 23, 23, and as shown in FIG. 3, the bolt 26 of the frame body 19 has a large-diameter hole.
The nut 25 is screwed into the bolt 26 by projecting it downward through the bolt 22. Here, the large diameter hole 22 is formed as a round hole having a diameter much larger than the diameter of the bolt 26 (several times or more), and the bolt 26 is covered with a holding plate 27 having a diameter larger than that of the large diameter hole 22. The nut 25 is screwed after being inserted, and when the nut 25 is screwed to the bolt 26, the pressing plate 27 is pressed against the lower surface of the upper piece 24 of the receiving member 23 at the peripheral edge of the large diameter hole 22. Become. Therefore, the frame body 19 constituting the connecting plate 3 can be slid in the horizontal plane within a range in which the bolt 26 can move in the large diameter hole 22. As described above, the frame body 19 constituting the connecting plate 3 is attached to each corridor 2
It can be fixed to the frames 10 and 10 of a and 2b through the receiving members 23 and 23, and the frames 10 and 10 of the corridors 2a and 2b can be connected by the frame body 19 which constitutes the connecting plate 3. After connecting the skeletons 10 and 10 with the frame body 19 in this way, a corridor floor 28 is stretched on each of the skeletons 10 and 10 to finish the corridors 2a and 2b, and a flooring material 20 is stretched inside the frame body 19 to finish the connecting plate. It is a thing. For example,
After arranging a deck board etc. in the frame 10 and the frame 19, light concrete 29 is put on it and mortar 30
By flowing the iron and finishing the iron, the corridors 2a and 2b can be formed, and at the same time, the corridors 2a and 2b can be connected by the connecting plate 3 formed by the frame body 19 and the floor material 20.
By laying a decorative mat over the connecting plate 3 from above 2b, it is possible to finish the appearance in which the corridors 2a and 2b are integrally continuous as shown in FIG. In FIG. 1, 31 is a corridor eave ceiling, 32 is a connecting ceiling that connects the corridor eave ceilings 31 of the corridors 2a and 2b, and the connecting ceiling 32 is preferably slidably connected to each corridor eave ceiling 31. . Also in FIG.
37 is a drain. Further, rock wool 34 is located under the corridors 2a and 2b.
To improve the fire resistance. Then, by connecting the corridors 2a and 2b with the connecting plate 3, the buildings 1a and 1b can be connected to each other so that the pair of buildings 1a and 1b can be treated as one building. It is possible. And although it is treated as one building under the law, each building 1a, 1b is structurally completely independent of each other, so when the building 1a, 1b shakes due to an earthquake or the like, each building 1a, 1b 1b will sway in different states independently of each other, but since the connecting plate 3 can slide as described above, a shift stress or the like acts between the connecting plate 3 and the corridors 2a, 2b. Even if this displacement stress is absorbed by the sliding movement of the connecting plate 3, it is possible to prevent the connecting portion between the connecting plate 3 and the corridors 2a and 2b from being damaged or the connecting plate 3 from being damaged. Is.

【The invention's effect】

As described above, in the present invention, since the connecting plate is installed between the adjacent ends of the corridors of the pair of buildings, and the connecting plate is slidably connected to at least one of the corridors, the building is constructed. Even if the rocks move independently and the shear stress acts between the connecting plate and the corridor, this shear stress is absorbed by the sliding of the connecting plate, and the joint between the connecting plate and the corridor is damaged. The connection plate can be prevented from being damaged. In addition, a receiving material is attached to each of the adjacent ends of the corridors of a pair of buildings, and a large diameter hole with a diameter much larger than the diameter of the bolt is provided in the receiving material, and a connecting plate is bridged over both receiving materials. With the bolt protruding from the lower surface of the connecting plate through the large diameter hole, insert the pressing plate with a diameter larger than the large diameter hole into the bolt and screw the nut onto the bolt Since the connecting plate is slidably connected to the corridor by sandwiching the receiving plate, the connecting plate can be slid with respect to the receiving plate within the range of the distance of the difference in diameter between the large diameter hole and the bolt. In addition to being slidable in the corridor, even if the connecting plate slides, the bolts of the connecting plate that pass through the large diameter hole of the receiving member will not come off from the large diameter hole. Even if the vibration of the Without that ride resulting in missing bolster from the coupling plate and the presser plates is restricted, but there is no possibility that outside coupling corridor by connecting plate.
