Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a skip-floor type building in which the floor heights of intermediate floors are different, and in particular, an axis structure in which beams are prioritized over columns. Regarding things with set structure.

BACKGROUND ART FIG. 10 shows a conventional example of a skip floor type building, in which a structural column 3 common to both sections is placed between a three-story section 1 and a two-story section 2. The ends of the beams 4 and roof beams 5 of each intermediate floor are joined to the side surfaces of the pillars 3 to form a single structure as a whole. Furthermore, as shown in FIG. 11, it is conceivable that the common structural column 3 is divided into sections corresponding to the ends of the beams 4 of the intermediate floor, so that the entire structure has a complete beam-priority structure.

Problems to be Solved by the Invention In the conventional structure described above, in the structure shown in FIG.
Since the structural column 3 has a column-prioritized structure in which it penetrates the shaft 4 in the vertical direction, the concept of beam-priority is partially broken, and the structure is complex, making structural calculations during design extremely difficult. There are drawbacks.

On the other hand, in the case of Fig. 11, beams are given priority as a whole, but since the second floor part 1 and the third floor part 2 share the same structural column 3, the structural calculation is still complicated. It has its drawbacks.

Furthermore, in any of the above cases, as shown in FIG.
If a staircase space 6 is used to connect the two spaces 2 and 3, a beam cannot be provided in this area, resulting in a structure that is difficult to pass through.

The object of the present invention is to realize a skip floor type building with a beam-priority structure that eliminates these conventional drawbacks.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention provides a first frame structure in which the floor beams and roof beams of each floor penetrate horizontally through the columns; A second frame structure in which the floor beams and roof beams of each floor pass through in the horizontal direction, and the floor beams of the intermediate floors have a different height from the first frame structure, with a skip zone between them. provided and arranged opposite to each other, one of them
The floor beams and roof beams of the floors are integrally connected, and on both sides of the skip zone between each frame structure, through columns are provided from the roof beams to the floor beams of the first floor, and the ends of the floor beams of the intermediate floors are provided. In this invention, each frame structure with different heights of the floor beams on the intermediate floor constitutes a separate structure of the lattice-priority type. Structural calculations may be performed for each frame structure. Then, the stairs can be placed in the skip zone between both frame structures, and for this reason even if the frame structures are placed apart from each other,
Since the two are connected by a through-pillar, the outer wall will not shake significantly during an earthquake.

Embodiment In FIGS. 1 and 2, 11 is a column 12.1 on each floor.
For 2..., the floor beam 13 on the first floor and the floor beam 14 on the intermediate floor
．． 14 and a roof beam 15 penetrated in the horizontal direction, and 16 is a frame structure of a three-story part in which each floor beam 13.14 and roof beam 15 penetrated in the horizontal direction with respect to the column 12.12. The frame structure of the story section is shown. Note that the floor beams 13 on the first floor include what is called a foundation beam or foundation.

Each of the above-mentioned frame structures 11.16 includes each pillar 12, a shaft 13.1
4.15 is an independent structure composed of
Structural calculations etc. can be performed separately. These frame structures 11, 16 are arranged facing each other with a skip zone 17 between them, and the floor beams 13 and roof beams 15 of each first floor are integrally connected. In this embodiment, the floor beam 13 and the roof beam 15 are integrally formed with each other. Skip zone 17 includes a staircase 18 that connects the 1102nd floor of the 3-story section and the 1602nd floor of the 2-story section;
And its two-story part 1602nd floor and three-story part 15-3
Stairs 19 are provided to connect the floors.

On both sides of this skip zone 17, through columns 20 are provided up to the floor beam 13 or roof beam 15 of the first floor, and each frame structure 1
The ends of the 2 and 3 wI floor beams 14 extending from 1.16 are joined to this through column 20. In this embodiment, the through column 20 is divided into two parts, upper and lower, and is joined to the lower or upper surface of the floor beam 14 extending from the frame structure 16 of the second floor.

3 and 4 show another embodiment of this invention, and in FIG. 3, both sides of the third floor pillar 12 of the three-story frame structure 11 on the opposite frame structure 16 side are shown. The pillars 12 are moved to both sides of the skip zone 17 compared to the pillars 12.12 on other floors.

On the other hand, in FIG. 4, the through-pillars 20 are connected to the columns 14 of each intermediate floor.
14... are divided into sections, and the through columns 20, 20... are connected to the upper and lower surfaces of each floor beam 14.

5 to 9 show a more specific structure of the present invention, and as shown in FIGS. 6 and 7, each rice bowl 13.
Both the column 14.15 and the column 12 are made of H-beam steel, and the joint plate 21 at the upper or lower end of the through column 20, which is divided into two, is attached to the upper and lower surfaces of the end of the column 14 on the second floor of the two-story part.
It is joined by 2. On the other hand, as shown in FIGS. 8 and 9, all! Building part 11 (71>2 ・3w!) Beam 1
4.14 has the same cross section as those katana 14, and the through pillar 2
The connecting plate 24 is connected to a short connecting beam 23 projecting from the side surface of the connecting plate 24 by bolts 25.

In addition, in FIG. 5, a vertical reinforcing plate 26 is welded to the center of the web of some of the columns 12. In addition, as shown in FIGS. 6 and 7, the through-pillar 20 has a flange at its end cut into a small width, and has a cross-shaped end formed by a reinforcing plate 27 welded to a web 28 and the web 28. The joining plate 21 is welded to the portion.

Effects of the Invention As described above, according to the present invention, each frame structure has a mutually independent beam-priority structure, and structural calculations can be easily performed for each frame structure. Become. Since both frame structures are placed facing each other with a skip zone between them, it is necessary to move or remove the beams of the frame structures by providing stairs in this area. This has the effect of avoiding such inconveniences. In addition, because through-pillars are provided on both sides of the skip zone, and the ends of the scallop extensions of each frame structure are connected to these through-pillars, the outer walls on both sides of the skip zone will sway greatly due to shaking during an earthquake. This eliminates the inconvenience of peeling off.
