Hereinafter, preferred embodiments of the present invention will be described in detail. The present embodiment described below does not unreasonably limit the content of the present invention described in the claims, and all the configurations described in the present embodiment are indispensable as a means for solving the present invention. Not necessarily.

1. 1. Outline of the first to third embodiments of the present invention FIG. 1 shows the building unit structures 100, 200, 300 according to the first to third embodiments of the present invention and the building unit structure 1 of Patent Document 2. Shown in comparison. The figures shown below show the two-story structure of the building unit structures 1, 100, 200, 300, etc., one downstairs and one upstairs, but the same applies to each floor having three or more floors. In FIG. 1, the interior space heights H1, H2, and H3 from the floor surfaces 141,241,341 to the ceiling surfaces 151,251,351 of each floor of the building unit structures 100, 200, and 300 are shown in the building unit of Patent Document 2. It is compared with the indoor space height H0 from the floor surface 41 to the ceiling surface 51 of the structure 1. In FIG. 1, the height positions of the ceiling surfaces 51, 151, 251 and 351 are set to be the same. However, the ceiling surface 51 of Patent Document 2 is lower than the upper surface of the ceiling beam 20 because it is provided in a form of being suspended by a suspension bolt from a suspension bolt receiver provided on a member installed on the upper surface of the ceiling beam 20. On the other hand, in the building unit structures 100, 200, 300, the ceiling surfaces 151,251,351 are higher than the upper surfaces of the ceiling beams 120,220,320 by adopting the mounting structure as described later. On the other hand, the floor surfaces 141, 241, 341 are lower than the height position A of the floor surface 41 extended by the alternate long and short dash line. From FIG. 1, it can be seen that H1 = H2>H3> H0. However, the distances h between the ceiling beams 20, 120, 220, 320 downstairs and the floor beams 10, 110, 210, 310 upstairs are all the same, and there is a predetermined space between the ceiling beams and the floor beams. It is secured. As a result, according to the first to third embodiments of the present invention, the piping space and the covering space of the fireproof material between the ceiling beams 120, 220, 320 and the floor beams 110, 210, 310 are equivalent to those of Patent Document 2. It can be seen that the indoor space heights H1, H2, and H3 from the floor surface 141,241,341 to the ceiling surface 151,251,351 are higher than H0 of Patent Document 2 while ensuring the above. The relationship between the floor surfaces 41, 141,241,341 and the ceiling surfaces 51,151,251,351 under the ceiling beams L0, L1, L2, L3 is L0 = L1 = L2 = L3. ..

2. 1st Embodiment of this invention FIG. 2 to FIG. 4 is a front view, a plan view, and a side view which shows the cross section of the framework of the building unit structure 100 which concerns on 1st Embodiment of this invention. The framework of the building unit structure 100 connects the floor beam 110, the ceiling beam 120, and the pillar body 130. The floor beam 110 and the ceiling beam 120 are formed of, for example, H steel. The floor beam 110 includes a plurality of types of floor beams 110A, 110B, 110C having different lengths, for example, three types. As shown in FIGS. 2 and 4, the ceiling beam 120 includes a plurality of types, for example, three types of ceiling beams 120A, 120B, and 120C having different lengths. The pillar 130 is a joint between the four corners of the building unit structure 100 and the floor beams 110A and 110B.
Includes one hand portion and one joint portion of the ceiling beams 120A and 120B, for example, a total of six. Note that FIGS. 2 to 4 show a building unit structure 100 having a total length of, for example, 40 feet. For example, in the case of the building unit structure 100 having a total length of 20 feet, it is sufficient to provide four pillars 130 at the four corners as shown in FIG.

As shown in FIG. 2, the column 130 has a hollow cross-section of, for example, a rectangular column 132, a through diaphragm 134 joined or welded to the lower end of the column 132, and a connecting plate 136 joined or welded to the upper end of the column 132. And a ceiling beam connecting fitting 138 joined to the column 132 below the connecting plate 136, for example, welded. The ends of the floor beams 110 are joined, for example, welded to the through diaphragm 134. The connection plate 136 is fastened to the through diaphragm 134 of the building unit structure 100 on the upper floor by fastening means such as bolts and nuts at four places outside the pillar 132, for example. The end of the ceiling beam 120 is fastened to the ceiling beam connection fitting 138 by fastening means such as bolts and nuts.

FIG. 6 shows an enlarged view of the downstairs / upstairs connection portion of FIG. As shown in FIG. 6, the floor beam 110 (110A, 110B, 110C) has a refractory material 114 that covers the H steel 112, which is a main structure rigidly joined to the through diaphragm 134. On the other hand, the ceiling beams 120 (120A, 120B, 120C) which are pin-joined to the ceiling beam connecting metal fittings 138 and do not form the main structure are not covered with the refractory material 114.

FIG. 6 shows the floor material 140 upstairs and the ceiling material 150 downstairs. The floor beam 110 is welded to the through diaphragm 134 welded to the lower end of the column 132. The floor material 140 is supported by the floor beam 110. On the other hand, the ceiling beam 120 is fastened to the ceiling beam connecting metal fitting 138 welded to the pillar 132 at a position separated below the connecting plate 136 at the upper end of the pillar 132 by the fastening means. Therefore, the mounting height position of the ceiling beam 120 is lowered, and a piping space and a space for covering the fireproof material can be secured between the ceiling beam 120 and the floor beam 110. Here, the mounting height position of the ceiling beam 120 is lowered, but the ceiling surface 151 does not need to be lowered in the region other than the ceiling beam 120. Next, the floor surface 141 of the floor material 140 is higher than the boundary surface A downstairs / upstairs by at least the height of the floor beam 110 and the height of the floor material 140. However, in the building unit structure 1 of Patent Document 2 shown in FIG. 1, the floor surface 41 of the floor material 40 is at least the height of the floor beam 10 and the height of the floor material 40 with respect to the boundary surface A downstairs / upstairs. In addition, the distance between the ceiling beam 20 downstairs and the floor beam 110 upstairs is further increased by the distance h. Therefore, as shown in FIG. 1, the interior space height H1 from the floor surface 141 to the ceiling surface 151 of each floor of the building unit structure 100 is higher than the interior space height H0 of the building unit structure 1 of Patent Document 2. It becomes wider (H1> H0).

FIG. 20 shows the floor material 340 upstairs and the ceiling material 350 downstairs. The floor beam 310 is welded to the through diaphragm 334 which is welded to the lower end of the column 332. The floor material 340 is supported by a floor beam 310 welded to the through diaphragm 334. Here, an additional column 336 welded to the lower end of the through diaphragm 334 and a lower connecting plate 337 welded to the lower end of the additional column 336 are further provided. Therefore, the position of the floor surface 341 of the floor material 340 supported by the floor beam 310 is higher than that of the first and second embodiments. In FIG. 20, the lower surface of the floor beam 310 is set at a position higher than the downstairs / upstairs boundary line A by the dimension h1. On the other hand, the ceiling beam 320 is fastened to the ceiling beam connecting metal fitting 338 welded to the pillar 332 at a position separated below the upper connecting plate 335 by the fastening means. Therefore, the mounting height position of the ceiling beam 320 is lowered. In FIG. 20, the upper surface of the ceiling beam 320 is set at a position lower than the downstairs / upstairs boundary line A by the dimension h2. It should be noted that h1 + h2 = h, and the distance h between the floor beam 310 and the ceiling beam 320 is the same in the first to third embodiments. Therefore, a piping space and a space for covering the refractory material can be secured between the ceiling beam 320 and the floor beam 310. Here, the mounting height position of the ceiling beam 320 is lowered, but the ceiling surface 351 does not need to be lowered in the region other than the ceiling beam 320.

5. Fourth Embodiment FIG. 24 shows a connecting area between the downstairs and the upstairs in the building unit structure according to the fourth embodiment of the present invention. The framework of the building unit structure 400 connects the floor beam 410, the ceiling beam 420, and the pillar body 430. The column 430 has a hollow cross section of a column 432, a through diaphragm 434 welded to the lower end of the column 432, an upper connecting plate 435 welded to the upper end of the column 432, and a hollow cross section welded to the lower end of the through diaphragm. It has an additional column 436, a lower connecting plate 437 welded to the lower end of the additional column 436, and a ceiling beam connecting fitting 438 welded to the column 432 directly below the upper connecting plate 435. The ends of the floor beams 410 are joined, for example, welded to the through diaphragm 434. The upper connecting plate 435 is fastened to the lower connecting plate 437 of the building unit structure 400 on the upper floor at four places outside the pillar 432, for example, by fastening means such as bolts and nuts at the site. The end of the ceiling beam 420 is fastened to the ceiling beam connection fitting 438 at the factory by fastening means. The floor beam 410, which is the main structure rigidly joined to the through diaphragm 434, has a refractory material 414 that covers the H-steel 412. The ceiling beam 420, which is not the main structure, is lower than the height of the floor beam 410.

FIG. 24 shows the floor material 440 upstairs and the ceiling material 450 downstairs. The floor material 440 is supported by a floor beam 410 welded to the through diaphragm 434. Here, an additional column 436 welded to the lower end of the through diaphragm 434 and a lower connecting plate 437 welded to the lower end of the additional column 436 are further provided. Therefore, the position of the floor surface 441 of the floor material 440 supported by the floor beam 410 is higher than that of the first and second embodiments, while the ceiling beam 420 is welded to the column 432 directly under the upper connecting plate 435. It is fastened to the ceiling beam connecting metal fitting 438 by the fastening means. Therefore, the mounting height position of the ceiling beam 420 is at the highest position, which is higher than that of the first and second embodiments. That is, in FIG. 24, it is the same as the state in which the floor beams and the ceiling beams of the first and second embodiments are translated upward by the dimension h. Therefore, also in the fourth embodiment, the distance between the floor beam 410 and the ceiling beam 420 is h, as in the first to third embodiments. Therefore, a piping space and a space for covering the refractory material can be secured between the ceiling beam 420 and the floor beam 410. Here, the mounting height position of the ceiling beam 420 is lowered, but the ceiling surface 451 does not need to be lowered in the region other than the ceiling beam 420, and the ceiling surface 451 can be secured high. However, since the floor surface 441 becomes higher depending on the position of the floor beam 410, the indoor space height H4 from the floor surface 441 to the ceiling surface 451 of each floor is the heights H1 to H3 of the first to third embodiments. Is narrowed down. However, since the ceiling beam 420 having a height lower than that of the floor beam 410 is used, even if the indoor space height H4 from the floor surface 441 to the ceiling surface 451 is equivalent to H0 as compared with Patent Document 2. , The interval L4 from the floor surface 441 to the ceiling surface 451 under the ceiling beam 420 is widened (L4> L0). Therefore, since the height of the ceiling surface 451 under the ceiling beam 420 is increased, the height of the indoor space from the floor surface 441 to the entire ceiling surface 451 is not narrowed to the extent that the comfortability is lowered. In addition, the ceiling beam 420 has a degree of freedom that can be removed and installed at the site. When the ceiling beam 420 is removed, the ceiling surface 451 can be set at a high position beyond the boundary surface between the downstairs and the upstairs. Therefore, the height of the indoor space is expanded, the livability is enhanced, and high openness can be ensured.

6. Fifth Embodiment FIG. 25 shows a connecting area between the downstairs and the upstairs in the building unit structure according to the fifth embodiment of the present invention. The frame of the building unit structure 500 connects the floor beam 510, the ceiling beam 520, and the pillar body 530. The column 530 has a hollow cross section of a column 532, a through diaphragm 534 welded to the lower end of the column 532, an upper connecting plate 535 welded to the upper end of the column 532, and a hollow cross section welded to the lower end of the through diaphragm. An additional column 536, a lower connecting plate 537 welded to the lower end of the additional column 536, and a ceiling welded to the column 532 directly below the upper connecting plate 535.
It has a beam connection fitting 538 and. The ends of the floor beams 510 are joined, for example, welded to the through diaphragm 534. The upper connecting plate 535 is fastened to the lower connecting plate 537 of the building unit structure 500 on the upper floor at four places outside the pillar 532, for example, by fastening means such as bolts and nuts at the site. The end of the ceiling beam 520 is fastened to the ceiling beam connection fitting 538 at the factory by fastening means. The floor beam 510, which is the main structure rigidly joined to the through diaphragm 534, has a refractory material 514 that covers the H-steel 512. The ceiling beam 520, which is not the main structure, has the same height as the floor beam 510, unlike the fourth embodiment.

FIG. 25 shows the floor material 540 upstairs and the ceiling material 550 downstairs. The floor material 540 is supported by a floor beam 510 welded to the through diaphragm 534. Here, the fifth embodiment is different from the fourth embodiment in that the height of the ceiling beam 520 is higher than that of the ceiling beam 420. As described above, since the fifth embodiment has the same structure as the fourth embodiment except for the height of the ceiling beam, the position of the floor surface 541 of the floor material 540 supported by the floor beam 510 is the first. While the height is higher than that of the second embodiment, the ceiling beam 520 is fastened to the ceiling beam connecting fitting 538 welded to the pillar 532 directly under the upper connecting plate 535 by the fastening means. Therefore, the mounting height position of the ceiling beam 520 is at the highest position, which is higher than that of the first and second embodiments. Further, also in FIG. 25, it is the same as the state in which the floor beams and the ceiling beams of the first and second embodiments are translated upward by the dimension h. Therefore, also in the fifth embodiment, the distance between the floor beam 510 and the ceiling beam 520 is h, as in the first to third embodiments. Therefore, a piping space and a space for covering the refractory material can be secured between the ceiling beam 520 and the floor beam 510. On the other hand, the height H5 of the indoor space from the floor surface 541 to the ceiling surface 551 of each floor is narrower than the heights H1 to H3 of the first to third embodiments. Compared with Patent Document 2, the indoor space height H5 from the floor surface 541 to the ceiling surface 551 is equivalent to H0 (H5 = H0), and the distance L5 from the floor surface 541 to the ceiling surface 551 under the ceiling beam 520. Is also equivalent (L5 = L0). However, the ceiling beam 520 has a degree of freedom that can be removed and installed at the site. When the ceiling beam 520 is removed, the ceiling surface 551 can be set at a high position beyond the boundary surface between the downstairs and the upstairs. Therefore, the height of the indoor space is expanded, the livability is enhanced, and a high degree of openness can be ensured.

As described above, in any of the first, third to fifth embodiments, the ceiling beams 120, 320 to 520 can be removed and installed at the site. FIG. 26 shows a construction example in which the ceiling beam 420 of the fourth embodiment is removed. As shown in FIG. 26, since the ceiling material 450 downstairs can be arranged directly under the floor beam 410 upstairs beyond the boundary surface A downstairs / upstairs at the site, the floor surface 441 to the ceiling surface 451 can be arranged. The indoor space height H4 can be expanded to the maximum. Therefore, for example, when a hotel is constructed using the building unit structures of the first, third to fifth embodiments, the ceiling height of the lobby on the first floor can be largely secured by removing the ceiling beams on the first floor.

Further, for example, in front of the loading platform of a trailer capable of carrying a 40-foot building unit structure, there is a protrusion called a gooseneck portion that interferes with a part of the floor beam. Floor beams having a shape that avoids interference may be joined. In this case, for example, in the first and second embodiments, an inner diaphragm is added above the through diaphragm at the lower end of the column, and the floor beam having a shape avoiding interference with the protruding portion is passed through and joined to the diaphragm and the inner diaphragm. Is also good.

Although not shown, the lower connection plate (flange) of the lowest layer building unit structure is fixed to a long anchor bolt embedded in the foundation concrete as a connection between the lowest layer building unit structure and the foundation. can do. In this way, it is possible to prevent the foundation concrete from being broken by the compressive load even in the case of a high-rise and heavy eight-story building, for example. The construction at this time is as follows, for example. First, the first nut screwed into the anchor bolt is adjusted to check the levelness of the horizontal plate supported on the first nut. Next, after removing the horizontal plate once, it is filled with mortar, and then the horizontal plate is placed again on the first nut. After the lower connecting plate (flange) of the lowermost building unit structure is placed on the horizontal plate, the lower connecting plate is fixed to the horizontal plate by the second nut. In this way, the lower connecting plate of the lowermost building unit structure can be fixed to the anchor bolt.
