(2) Small assembly (Figs. 5 and 6)
In order to form one small building unit 20, the lower ends of the two opposite end frames 21 are rigidly joined with a girder floor beam 22A, and the upper end is rigidly joined with a girder ceiling beam 23A. At the same time, the tip ends of the two floor beams 22B of the two frame frames are connected to each other by the connecting floor beam 24,
The tip of the end ceiling beam 23B is connected and pin-connected by the ceiling beam 25.

In this embodiment, a girder constituting a single small building unit 20 is composed of a girder floor beam 22A, a connecting floor girder 24, a floor girder, a floor joist and the like, and a girder constituting one small building unit 20. A ceiling frame 42 (FIG. 5) including the ceiling beam 23A, the connecting ceiling beam 25, and the ceiling joist 26 is formed. Then, the floor frames 41 constituting the two small building units 20 are temporarily connected via the intermediate temporary connection piece 33 and the ceiling frames 42 are temporarily connected via the intermediate temporary connection piece 33 (FIG. 5 ( A)), the floor frame temporary connection body and the ceiling frame temporary connection body are inserted between the two wife frames, and the lower ends of the pillars 21 of the two wife frames are connected to the girder floor beam 2 of the floor frame 41.

Next, the small building unit 20 is connected to the connected building 50 at the construction site in the following procedure (
FIG. 7). It is assumed that the connected building 50 is the standard building unit 10.

(1) Remove the temporary connection pieces 31 and 32 that temporarily connect the two small building units 20 on the transport vehicle or temporary storage, and collect them.

  (2) Lift the small building unit 20 and install it on the foundation or lower floor building structure.

(3) Connect each end of the end floor beam 22B and end ceiling beam 23B of the small building unit 20 to the connected building 5
Pin connections are made with bolts and nuts 51 to the lower end and the upper end of the pillar 11 of the standard building unit 10 (FIG. 8). At this time, the span between the floor floor beam 22B and the ceiling ceiling beam 23B of the small building unit 20 is shorter than the center inflection point R (FIG. 9) of the standard building unit 10, so that the small building unit 20 is connected. Even if pin-connected to the building 50, the horizontal strength equivalent to or higher than that of the standard building unit 10 is exhibited.

FIG. 10 shows another application example of the small building unit 20. The girder surfaces of the two standard building units 10 that will be the connected building 60 are butted together, the long beams 61 are bridged between these girder surfaces, and the columns 11 adjacent to each other are omitted. The small building unit 20 is provided along both wives (only one wives are allowed), and the front ends of the floor floor beams 22B and the ceiling beams 23B of the small building unit 20 are connected to the outer ends of the standard building units 10. The pillar 11 is pin-connected to the lower end and the upper end. The small building unit 20 and the connected building 60 can form a large room space without a pillar.

According to the present embodiment, the following operational effects can be obtained.
(a) The small building unit 20 is a pillar 2 in which the end face of the standard building unit 10 is roughly divided in half.
1. Since the girder floor beam 22A, the girder ceiling beam 23A, the end floor beam 22B, and the end ceiling beam 23B are configured, the pillar 11 and the beams 12A, 12B, 13A, 13B of the standard building unit 10 and the production equipment (
Production line) and transportation equipment (transportation vehicles) can be shared, improving production efficiency and transportation efficiency.

(b) The small building unit 20 uses only two columns 21 and is connected to the connected buildings 50, 60.
Since the column 21 is not provided on the joint surface, the structural strength is not excessive.

(c) Since the small building unit 20 includes the connecting floor beam 24 that connects the tip ends of the both ends floor beams 22B and the connecting ceiling beam 25 that connects the end portions of the both ends ceiling beams 23B, the floor in the small building unit 20 is provided. The ceiling can be easily formed, and the strength of the small building unit 20 can be secured.

By the above (a), (b), (c), without impairing the high-efficiency productivity and transportability of the unit construction method,
You can extend the building slightly.

(d) The small building unit 20 rigidly joins each of the girder floor beam 22A and the end floor beam 22B to the lower end portion of the column 21, and connects each of the girder ceiling beam 23A and the end ceiling beam 23B to the upper end portion of the column 21. It is constructed by rigidly connecting, pin-joining the floor beam 24 to the tip of both ends floor beam 22B, and pin-connecting the ceiling beam 25 to the tip of both ends ceiling beam 23B. Easy to build.

(e) Most of the horizontal force along the girder direction of the building extension formed by connecting the small building unit 20 to the connected buildings 50, 60 is obtained by using the two columns 21 of the small building unit 20, the girder floor beam 22A, and the girder. It is borne by a box-shaped ramen frame made by the ceiling beam 23A.

All the heavy outer wall openings attached to the girder surface of the building extension are covered by the box-shaped ramen frame described above.

(f) The horizontal force along the wife direction of the building extension is borne by two U-shaped ramen frames created by one pillar 21, the wife floor beam 22B, and the wife ceiling beam 23B of the small building unit 20. The small building unit 20 also contributes to the horizontal force reinforcement of the connected buildings 50 and 60.

(g) The box-type ramen frame bears the vertical load on the floor, ceiling, and roof on the outer wall side half of the building extension.

The vertical loads on the floors, ceilings, and roofs on the connected buildings 50, 60 side of the building extension are borne by the connecting floor beams 24 and the connecting ceiling beams 25 of the small building unit 20 during transportation.
After the connection, the floor beams 12A and 12B and the ceiling beams 13A and 13B of the connected buildings 50 and 60 are shared.

(h) In the above-mentioned (f), since the span of the end floor beam 22B and the end ceiling beam 23B of the small building unit 20 is shorter than the center inflection point of the standard building unit 10, the small building unit 20 is covered. Even if it is pin-connected to the connection building, a horizontal strength equal to or higher than that of the standard building unit 10 can be exhibited.

(i) The two small building units 20 are temporarily connected to produce and transport, and the small building units 20 are separated on site and connected to the connected buildings 50 and 60 to streamline production and transportation. In addition, it is possible to prevent the small building unit 20 from being overturned during production line or storage transportation.
