2. Description of the Related Art Generally, a unit box in a steel-framed unit construction house is designed so that the individual boxes are independent of each other and have sufficient strength. I am trying to do it. Therefore, for example, in the case of a long unit box having a long span, a steel material for a floor girder or a ceiling girder is also larger.

However, in this conventional structure, the strength required for the completed building is required in the adjacent portions of the girders of the unit boxes arranged side by side or in the portions where the girders of the unit boxes stacked one above the other overlap. The above steel materials are used, which is uneconomical. In addition, since the middle parts of the girders arranged vertically or horizontally are not joined, if the load on the floor of each adjacent unit box varies due to the presence or absence of a bathtub or other sanitary equipment, the unit boxes Floor irregularities may occur between them.

According to the beam intermediate portion joining structure of adjacent unit boxes of the present invention, two adjacent ceiling girders of lower unit boxes arranged in parallel are stacked on each of the lower unit boxes. Between the two adjacent floor girders of the upper floor unit box, the first joint plate is interposed at the longitudinal intermediate portion of these beams, and the second joint plate is used as the bottom plate portion of the two floor girders. And the first joint plate, and the first and second joint plates are bolted to each other. Pin insertion holes that are aligned with each other are provided in the upper surface plate portion of each ceiling girder and the lower surface plate portion of the floor girder that overlap with the first joint plate. A pin that fits into the pin insertion hole is provided on the lower surface of the second joint plate. In the beam intermediate portion joining structure, a plurality of locking claws may be provided on the lower surface of the first joining plate, the engaging claws respectively engaging with the lower surfaces of the upper surface plate portions of two adjacent ceiling girders.

According to this structure, the two ceiling girders adjacent to each other in the lower-floor unit boxes and the two floor girders adjacent to the upper-floor unit box stacked on top of each other are connected to each other. Are joined by the first joining plate and the second joining plate provided at the intermediate portion in the longitudinal direction. Therefore, the movement of these four beams is restrained at the intermediate portion in the longitudinal direction against the horizontal force, and the rigidity is increased. Therefore, even in the case of a long unit box, sufficient rigidity can be secured without designing the steel material forming the beam large. In addition, it is less likely that the floor will be uneven between adjacent unit boxes. Further, since the first and second joint plates and the respective girders are engaged with each other by pins so that both joint plates are bolt-joined, it is not necessary to provide a screw hole or a nut for bolt-jointing each girder. Thus, it becomes easy to process these girders. Moreover, the number of bolts for joining is small, and the bolt tightening work is not troublesome.

When a rotatable lower plate is provided on the lower surface of the first joining plate, the first joining plate is placed on the ceiling with the lower plate oriented in the direction along the gap between the upper plate portions of the two ceiling girders. It is placed on the girder and then the lower plate is rotated 90 ° to engage with the lower surface of the upper plate part of the ceiling girder. In the case of this configuration, the ceiling girder and the floor girder above it are vertically sandwiched between the lower plate and the second joint plate. Therefore, the four beams are constrained in the vertical direction, so that they perform the same movement like one beam, and the rigidity is further increased.

As a result, the ceiling girder 3 and the floor girder 4 are positioned by the pin 11 of the second joint plate 8 and the joint plates 7 and 8 are bolt-joined to each other. The movement is restricted to each other at the intermediate portion in the longitudinal direction. Therefore, rigidity is increased and vibration is reduced. Therefore, a member having a small cross-sectional shape can be used for each of the girders 3 and 4, and the amount of steel used can be reduced. Further, since the girders 3 and 4 are joined by the joining plates 7 and 8, the floor is not uneven. In this way, it is possible to make a unit building with high quality and easy cost.

Further, since the first and second joint plates 7 and 8 and the respective girders 3 and 4 are engaged with each other by the pin 11 so that both joint plates 7 and 8 are bolt-joined, each girder 3, 3. Four
Since it is not necessary to provide a screw hole or a nut for bolt connection to the beam, the girders 3 and 4 can be easily processed. Moreover, the number of bolts for joining is small, and the bolt tightening work is not troublesome. The nut 15 and the locking claw 16 need to be welded to the joint plate 7, but since they are small parts, the welding work can be easily performed. Further, the first joining plate 7
The auxiliary plates 9 and 9 which are stacked on the upper and lower surfaces respectively intervene in the gaps between the upper flanges 3a and 3a of the ceiling girders 3 and 3 and the lower flanges 4b and 4b of the floor girders 4 and 4, respectively. Therefore, the strength against the compressive load in the horizontal direction generated between the adjacent unit boxes is secured, and the buckling of the joint plate 7 is prevented.

EFFECTS OF THE INVENTION The beam intermediate portion joining structure of adjacent unit boxes according to the present invention has two ceiling girders adjacent to each other in the lower floor unit boxes and the upper floors stacked on the lower floor unit boxes. A first joint plate is interposed between the two adjacent floor girders of the unit box at the longitudinal intermediate portions of these beams, and pins are inserted into the upper surfaces of the joint plates and the lower plate portions of both floor girders. Since the second joint plates are overlapped with the holes and the pins fitted to each other and the first and second joint plates are bolt-joined to each other, these girders are integrated and rigidity is improved. Therefore, it is possible to use a thin member for each girder and reduce the amount of steel used without causing insufficient rigidity. In addition, since the adjacent girders are joined by the joining plate, there is no unevenness in the floor. Moreover, since the first and second joining plates and the girders are engaged with each other by pins, it is not necessary to provide a bolt hole or a nut for bolt joining to each girder, and the working of these girders is easy. Moreover, the number of bolts for joining is small, and the bolt tightening work is not troublesome. In this way, while obtaining high quality in terms of rigidity and prevention of unevenness of the floor,
The amount of steel used can be reduced, and the joining work of the middle part of the beam can be performed easily, resulting in a low-cost unit building. In the case of the structure of claim 2, since the first joint plate is locked to the ceiling girder by the locking claw, temporary fixing at the time of construction of the first joint plate can be easily performed.

In the case of the third aspect of the invention, the ceiling girder and the floor girder above it are vertically sandwiched between the lower plate and the second joint plate. Therefore, the four beams are constrained in the vertical direction, so that they perform the same movement like one beam, and the rigidity is further increased.
