In addition, the same number is attached | subjected to the building unit same as the first floor part 14, and the description is abbreviate | omitted.

  Here, in this embodiment, a pair of wife frame 34 (, 36) as the lower frame shown in FIG. 1 and a gate-type unit 38 (upper building unit) ( , 40), and a large vent 42 (44) communicating with the upper and lower floors for use as the elevator room 30 (and the staircase 32) is formed, which will be described in detail below. To do.

  As shown in FIG. 1, the wife frame 34 includes two pillars 46, a wife side ceiling beam 48 that connects the upper ends of the two pillars 46, and the lower ends of the two pillars 46. Are formed in a rectangular frame shape with the wife side floor girder 50 connecting the two. The pair of end face frames 34 are erected in parallel with each other at a position where the elevator chamber 30 (blow-out 42) of the first floor portion 14 is formed. That is, the girder-side ceiling girder and girder-side floor girder that connect the pair of end face frames 34 do not exist.

  As shown in FIG. 2, the gable side ceiling girder 48 and the gable side floor girder 50 of one gutter frame 34 are connected to the ceiling girder 52 and the floor girder (of the box-shaped unit 26 arranged orthogonal to the girder side girder. (Not shown) are joined by joining means such as bolts and nuts via a bracket (not shown). Further, the wife side ceiling girder 48 and the wife side floor girder 50 of the other end face frame 34 are not shown in the ceiling girder 54 and the floor girder (not shown) of the box-shaped unit 22 that are arranged adjacent to and parallel to each other. It is joined by joining means such as bolts and nuts via the bracket.

  A portal unit 38 for forming the upper side of the blow-outs 42 and 44 is connected to the upper ends of the pair of wife face frames 34 described above. The gate-type unit 38 is a pair of wives that connect the pillars 56 standing at the four corners and the upper ends of the pillars 56 that are disposed facing each other in the wife direction (that is, disposed on the face frame 34 side). The ceiling girder 58, the wife side floor girder 60 that connects the lower ends of the column 56, and the column 56 arranged opposite to each other in the girder direction (that is, arranged on the side where the wife face frame 34 is not arranged). And a plurality of ceiling beams 64 arranged at a predetermined interval between the pair of beam-side ceiling beams 62 and connecting the upper ends of the beam beams. The portal unit 38 includes a pair of side frames 66 as a pair of side frames having the same configuration as the pair of wife frames 34 arranged on the first floor portion 14, and the upper ends of the wife frames 66.

(Action / Effect)
Next, the operation and effect of this embodiment will be described.

  According to the present embodiment, a required number of box-shaped units 22, 24, 26, and 28 having a plurality of sizes are installed on the fabric base 12, and a total of three sets of the face frames 34 and 36 are box-shaped units. 28 on both sides. Thereby, the first floor portion 14 of the unit building 10 is formed. After the formation of the first floor portion 14, the required number of box units 22, 24, 26, 28 having a plurality of sizes are similarly installed in the box units 22, 24, 26, of the already installed first floor portion 14. A total of three sets of portal units 38 and 40 are installed. Thereby, the second floor portion 16 of the unit building 10 is formed. Finally, a plurality of roof units 70 (see FIG. 3A) are sequentially installed on the upper surface of the second floor portion 16, whereby the roof portion 18 of the unit building 10 is formed and the unit building 10 is constructed.

  In the unit building 10 constructed as described above, large atriums 42 and 44 extending from the first floor to the second floor are formed at two locations on the center side of the building. Of these, one of the vents 42 is used as the elevator chamber 30, and the other of the vents 44 is used as the staircase 32.

  Here, a blow-off 42 used as the elevator chamber 30 will be described as an example. In the present embodiment, the pair of end face frames 34 are opposed to each other and are erected in parallel, and are not connected to each other. Therefore, when the gate-type unit 38 is placed between the upper end portions of the gate-type unit 38, a beam shape does not remain on the wife direction side of the boundary position between the first floor portion 14 and the second floor portion 16. Accordingly, a wide atrium 42 without an obstacle is formed from the first floor to the second floor.

  In addition, to explain by taking as an example the atrium 44 used as the staircase 32, from the same reason (that is, the beam shape does not remain on the wife direction side of the boundary position between the first floor portion 14 and the second floor portion 16), The size of the atrium in the building horizontal direction is not limited to the unit size. Therefore, when the normal size wife face frame 34 and the gate-type unit 38 and the half size wife face frame 36 and the gate-type unit 40 are arranged in parallel as in this embodiment, the building has a horizontal spread. It is also possible to form the atrium 44 (that is, there are no obstacles in the horizontal direction of the building).

  Furthermore, since the beam does not exist as an obstacle inside the vents 42 and 44, the appearance of the vents 42 and 44 itself is very good.

  From the above three points, according to this embodiment, it is possible to make wide blow-outs 42 and 44 with good appearance.

  To supplement this point, in the case of the conventional unit building 100, as shown in FIGS. 4 to 6, the gate-type unit 102 is disposed on the first floor portion 104, and the box-shaped unit 108 is disposed on the second floor portion 106 thereon. Since the atrium 110 is formed by installation, the girder-side ceiling girder 112 of the portal unit 102 and the girder-floor girder 114 of the box-shaped unit 108 are beamed at the boundary between the first floor portion 104 and the second floor portion 106. It remains as a mold 116 (see FIG. 6). For this reason, the beam type 116 is limited in the size of the blow-through, and is present as an obstacle in the height direction, and the appearance is not good. However, in this embodiment, the lower part of the blow-throughs 42, 44 is not configured as a unit, but the frame is disposed oppositely, and the upper part of the blow-offs 42, 44 is configured by the portal units 38, 40. The structural problem is solved.

  Further, in the present embodiment, the beam material on the wife side of the frame frames 34 and 36 and the beam material on the wife side of the gate-type units 38 and 40 are joined to the box-shaped unit 22 in which the beam material is arranged in parallel thereto. If possible, it is also possible to join to the box-shaped unit 24 in which the beam material is arranged orthogonally. Accordingly, it is possible to increase the degree of freedom in planning the unit building.

  Furthermore, in the present embodiment, a temporary floor beam 72 (see FIG. 1) that can be removed at the building site between the lower ends of the pillars 46 of the portal units 38 and 40 that constitute the upper portions of the atriums 42 and 44 at the time of factory production. By spanning, stability during transportation can be ensured.

  Moreover, in this embodiment, since the cloth foundation non-formation part 20 was set in the site | part in which the hollow 44 of the cloth foundation 12 is formed, an obstruction does not exist in the position which partitions off the blow-off 44 and the building exterior. Therefore, for example, an atrium can be used as a parking space. Therefore, the degree of freedom of planning can be further increased in the sense that planning using the atrium 44 as a parking space is possible.

  In addition, you may take the structure which forms a fabric foundation continuously in the fabric foundation non-formation part 20 as it is. In this case, the atrium 44 cannot be used as a parking space, but a large opening 74 (see FIG. 3B) communicating with the atrium 44 can be formed on the side of the building. Therefore, for example, the atrium 44 can be used as an entrance hall or a courtyard. Therefore, the degree of freedom of planning can be further increased in the sense that planning using the atrium 44 as an entrance space or a courtyard becomes possible.

  Further, in the present embodiment, a blow-off 42 on the elevator chamber 30 side will be described as an example. As shown in FIG. 3 (A), a normal box shape is formed on both sides of the portal unit 38 arranged on the upper floor side. The units 22 and 24 are arranged adjacent to each other, and the ceiling surface frame 68 of the gate-type unit 38 is bridged between them and connected to each other. It does not exist, but can be used as a contribution to securing or improving the strength and rigidity of the unit building 10 as a whole. A higher reinforcement effect can be obtained by connecting adjacent beams with brackets (not shown) even between the box-shaped units 24 and 28 arranged adjacent to both sides of the portal unit 38 in the wife direction. Therefore, according to the present embodiment, the gate-type units 38 and 40 can be used for securing or improving the strength and rigidity of the entire building.

  Further, in the present embodiment, as shown in FIG. 3A, the portal unit 38 includes a ceiling surface frame 68 having the same configuration as the ceiling surface frame 76 of the box-shaped unit 22, so Can be used as a mounting surface. Therefore, it is possible to install the same roof unit 70 as the conventional one for the roof portion 18. That is, there is no need to change the design on the roof unit 70 side. Thus, according to this embodiment, since the same roof unit 70 as the conventional one can be installed, the productivity of the roof unit 70 and thus the unit building 10 can be maintained well.
