  Hereinafter, one embodiment of an incidental structure concerning the present invention is described in detail based on a drawing. First, the building unit 1 for connecting and fixing the incidental structure will be described. 1 and 2, the building unit 1 has a box ramen structure formed by joining steel structural members into a rectangular parallelepiped shape by welding, and includes four column members 2, 2,. Long side direction lower beams (floor beams) 3, 3 connecting the lower ends of the column materials in the horizontal direction, short side direction lower beams (floor beams) 4, 4, and four column materials 2, 2, ... Are formed in a rectangular parallelepiped shape from upper beams (ceiling beams) 5 and 5 in the long side direction and upper beams (ceiling beams) 6 and 6 in the short side direction. In the building unit 1, floor joists 7, 7... Are installed between the lower beams 3 and 3 at a predetermined interval, and ceiling joists 8, 8. Each column member and each beam member are welded with reinforcing plates 9, 9... Interposed at the corners to enhance the rigidity of the building unit 1.

  In the rectangular parallelepiped of the building unit 1, the long side direction will be described as the X direction, the short side direction as the Y direction, and the height direction as the Z direction. The building unit 1 is, for example, a long side having a length of about 4 to 5 meters in the long side direction (X direction), a length of about 2 to 3 meters in the short side direction (Y direction), and the height direction. It is formed in a rectangular parallelepiped shape having a length of (Z direction) of about 2.5 to 3 meters. That is, the building unit 1 has two elevation surfaces (XZ plane) along the long side direction, two elevation surfaces (YZ plane) along the short side direction, an upper surface, and a bottom surface (XY plane). It is comprised from these six surfaces.

  The incidental unit 10 connected and fixed to the building unit 1 has a small rectangular parallelepiped shape, and is provided on one side of the building unit 1 having a rectangular parallelepiped shape having six surfaces (YZ plane). It has the same rectangular side surface as the short side surface, and the length along the long side direction of the building unit 1 is set to be short. For example, while the length of the long side direction of the building unit 1 is about 4 to 5 meters, the length of the accessory unit 10 in the X direction is set to about 1 meter or a short length of 1 meter or less. ing.

  The accessory unit 10 has a small rectangular parallelepiped shape as shown in FIGS. 2 to 7, and four columnar members 11, 11... Made of channel steel or C-shaped steel whose cross-sectional shapes are substantially U-shaped. The two lower beams 12, 12 connecting the lower ends of these column members in the X direction, the two lower beams 13, 13 connecting in the Y direction, and the upper ends of the column members are connected in the X direction. It consists of two upper beams 14 and 14 and upper beams 15 and 15 connected in the Y direction. In the present embodiment, the side unit rectangle of the building unit 1 in the YZ direction and the side unit rectangle of the auxiliary unit 10 in the YZ direction have the same shape. With this configuration, when the incidental unit 10 is connected and fixed to the building unit 1, the building unit 1 is extended in the longitudinal direction (X direction) and has a shape in which no protruding portion or stepped portion is generated. The rectangular shape of the side surface in the YZ direction of the building unit 1 and the rectangular shape of the side surface in the YZ direction of the accessory unit 10 may not be the same shape, but may be a shape in which a stepped portion or a protruding portion is generated when connected.

  The four column members 11 constituting the incidental unit 10 are formed of groove-shaped steel or C-shaped steel material having a substantially U-shaped cross section. The structure is different from the formed pillar material, and the weight of the incidental unit 10 and the cost can be reduced. Since the accessory unit 10 is basically connected and fixed to one elevation surface of the adjacent building unit 1, the structure depends on the strength of the basic building unit 1, and the strength of the accessory unit 10 itself is Even if it is loose, there is no problem.

  That is, the incidental unit 10 is basically configured flexibly, easily follows the building unit 1 to be connected, and can flexibly absorb even when wind pressure or seismic force (external force) is applied. That is, when the incidental unit 10 is connected to the building unit 1, it is integrated with the building unit 1, and wind pressure and seismic force (external force) acting on the part are transmitted to the building unit 1 of the main body. It has a structure that does not compete. For this reason, it can suppress that an excessive force is applied to the junction part of the building unit 1 and the incidental unit 10.

In addition, you may reinforce by connecting a brace material in the inclined state to the rigid joint surfaces 16 and 16 of a XZ direction.

  In addition, although the two side surfaces of the incidental unit 10 have shown examples of rigid joint surfaces, a configuration other than a rigid joint surface may be used. For example, the upper beams 14 and 14 along the X direction are welded to the upper ends of the column members 11 and 11. The lower beams 12 and 12 may be connected to the lower ends of the column members 11 and 11 with bolts and nuts or the like as fixtures to form side surfaces 16 and 16. In other words, the upper beam 14 is joined to the upper ends of the column members 11 and 11 to form a gate shape, and the lower beam 12 is connected to the lower end of the gate shape with a fixture such as a bolt and nut to form the side surface 16. Good. Further, the upper beam 14 and the lower beam 12 may be connected to the upper and lower ends of the column members 11 and 11 with a fixture such as a bolt and nut to form the side surface 16 by pin joining. Details of these embodiments will be described later.

  For example, as shown in FIG. 3A, the incidental unit 10 is overlaid by being attached and fixed to the second floor building unit 1 on the upper floor of the first floor building unit 1A. It is connected and fixed to the state. In this case, you may comprise so that the auxiliary pillar H may be provided under the incidental unit 10. FIG. In FIG. 3B, the building unit 1 is installed and fixed above the foundation K, and the incidental unit 10 is connected and fixed to the building unit 1.

  Here, the detail of the incidental unit 10 is demonstrated based on FIGS. The lower beams 13 and 13 and the upper beams 15 and 15 constituting the auxiliary unit 10 are bolted to the column members 11 and 11 as described above. That is, the two reinforcing plates 20 and 20 are horizontally welded or the like so as to close the opening of the C-shaped steel at the lower end of the grooved steel or C-shaped steel having a substantially U-shaped cross section constituting the column member 11. The distance between the two reinforcing plates coincides with the height of the lower beam 13. In addition, two reinforcing plates 21 and 21 are welded horizontally by welding or the like so as to close the opening of the C-shaped steel in the same manner at the upper end of the column 11 made of C-shaped steel having a U-shaped cross section. In addition, the interval between the two reinforcing plates matches the height of the upper beam 15.

  And the joint plates 22, 22,... Are fixed vertically by welding or the like so as to connect the two reinforcing plates 20, 20, 21, 21, and the outer end face of the C-shaped steel.

End plates 13a and 15a that are in contact with the joint plate 22 are fixed to the lower beams 13 and 13 and the upper beams 15 and 15 so that bolts 23 can be inserted into the through holes 24, 24. Holes 13b and 15b are formed. As described above, the upper beams 15 and 15 and the lower beams 13 and 13 are joined by the bolts and nuts 23 via the joint plates 22.

  In the column members 2 and 2 of the building unit 1, two attachment holes 30 are provided in each of the upper and lower ends facing the incidental unit 10 of the column members 2 and 2 as a configuration for connecting the incidental unit 10 to the building unit 1. , 30 are formed, and nuts 32, 32 to which bolts 31, 31 for connecting and fixing the accessory unit 10 to the building unit 1 are screwed are fixed by welding or the like. A guide pin 33 is fixed via a nut or the like in the middle of the mounting hole in which the two nuts are welded. The guide pin 33 is for positioning so as to facilitate bolting when the accessory unit 10 is connected and fixed to the building unit 1, and the tip of the guide pin 33 is tapered.

  In the incidental unit 10, three through holes 27 are formed on the surfaces of the pillar members 11, 11 facing the building unit 1 corresponding to the mounting holes 30 of the building unit 1 and the guide pins 33. Bolts 31 are inserted into the upper and lower two through holes, and a guide pin 33 is inserted into the central through hole. A spacer 35 is interposed between the pillar material 2 of the building unit 1 and the pillar material 11 of the incidental unit 10. The spacer 35 is formed with a through hole into which the bolts 31 and 31 and the guide pin 33 can be inserted.

  In the incidental unit 10 formed in this way, the column member is a rectangular column and the beam unit is a grooved steel or C-shaped steel, and two surfaces ( (X-Z plane) is rigidly joined, and the rigid joint surfaces 16 and 16 are connected by four beam members 13, 13, 15 and 15 by bolts and nuts 23. It is possible to reduce the weight of the column material and the beam material, and to reduce the cost.

  In addition, the accessory unit 10 is transported by being divided into two rigid joint surfaces 16 and 16 and four beam members 13, 13, 15, and 15, which are composed of the column members 11 and 11, the lower beam 12, and the upper beam 14. The construction is such that beam materials are fixed and assembled locally. In the illustrated embodiment, as the two rigidly joined surfaces of the rectangular parallelepiped constituting the accessory unit 10, two surfaces in the XZ direction are used, but two surfaces in the YZ direction are used as the rigidly joined surfaces. Of course, it is good. The accessory unit 10 may be formed by bolting four column members, four lower beams, and four upper beams, and is formed by combining rigid bonding by welding and pin bonding by bolts and nuts.

As shown in FIG. 4, the pillar material B of the balcony constructed on the auxiliary unit 10 can be connected and fixed to the upper end of the pillar material 11 as shown in FIG. 4.

  As shown in detail in FIGS. 8 and 9, the accessory unit 10 of the present embodiment has four joint members 15 c, 15 c... Fixed to the upper beams 15, 15 constituting the ceiling surface, and a rectangular shape between the joint members. The frame 40 is fixed. The joining member is formed of vertical C-shaped steel, and a plate material is fixed to the upper and lower openings by welding or the like. The rectangular frame 40 is formed by crossing long beams 41, 41 along the long side direction and short beams 42, 42 along the short side direction and joining them by welding or the like, and has a U-shaped cross section or C It is formed from shape steel. The rectangular frame 40 is located inside the four upper beams 14, 14, 15, 15 constituting the ceiling surface of the accessory unit 10, and the upper surface of the rectangular frame coincides with the upper surfaces of the four upper beams. As described above, the joint members 15c and 15c are connected and fixed flush with each other by bolts and nuts 43.

  The incidental unit 10 of the present embodiment configured as described above has a flexible structure so as to follow the building unit 1 to be basically connected as described above, but the ceiling surface is an upper beam. The inner frame is reinforced by a rectangular frame 40 that is fixed flush with the upper beam, so that the structural strength is increased. The region inside the rectangular frame 40 is formed as a sturdy opening. For this reason, when building a unit building by combining a plurality of building units 1 and ancillary units, and when roofing the roofing material, an opening such as a skylight can be formed, and an opening is provided. In addition, the structural strength of the ceiling surface increases, so that deformation of the accessory unit can be prevented. Since the rectangular frame 40 is fixed with bolts and nuts between the upper beams 15 and 15 via the joining members 15c and 15c, when a force is applied to the auxiliary beam, the load is shared by the upper and lower flanges of the upper beam. The strength can be increased. Further, when the joining member 15c is fixed to the upper beam, a space is formed on the back side, and a bolt or a nut can be mounted on the back side of the joining member, so that the auxiliary beam can be easily installed. .

  As described above, the rectangular frame 40 constituted by the long beams 41 and 41 parallel to the four upper beams constituting the ceiling surface and the short beams 42 and 42 is fixed to the ceiling surface of the incidental unit 10 by the bolt nuts 43. Therefore, the structural strength of the ceiling surface is increased. For this reason, an opening such as a skylight can be freely formed in the rectangular frame 40. For example, a frame is formed on the ceiling joist 44 of the incidental unit 10 with wooden crosspieces 45, 45, a vertical crosspiece 46 is connected to the frame, and an inclined frame is further formed with the horizontal crosspiece 45. An opening S can be formed by fixing a skylight 47 made of a light-transmitting material such as a glass plate to the roof and rolling the periphery with a roofing material. A tread board 48 is placed on the ceiling joist 44 so that the operator does not step on the foot during work, and is removed after the work is finished.

The bolts 23 are inserted by aligning the through holes 13b and 15b, and a nut is screwed and fixed. Bolts and nuts can be inserted into the column member 11 by the narrow portion of the joint plate 22. Thereby, the side surfaces 16 and 16 are couple | bonded by four beam materials, and the rectangular parallelepiped incidental unit 10 is completed.

  The accessory unit 10 configured as described above is small and divided into two face members (side surfaces that are rigidly joined) 16 and 16 and four beam members (lower beams 13 and 13 and upper beams 15 and 15). Therefore, it can be easily transported. Moreover, since the incidental unit 10 does not require strength, the column member 11 and the beam members 12, 13, 14, and 15 can be small and light, the weight of the incidental unit 10 can be reduced, and the cost can be reduced. Furthermore, the side surfaces 16 and 16 can be made into rigid joint surfaces by welding, and the rigid joint surfaces can be connected by four beam members to form a rectangular parallelepiped accessory unit, which eliminates the need for large-scale manufacturing equipment such as a building unit. Thus, it can be easily manufactured.

  In the incidental unit 10 of this embodiment, the rectangular frame 40 is connected and fixed to the upper beams 14 and 14 and the upper beams 15 and 15 constituting the ceiling surface, and the structural strength of the ceiling surface is increased. Therefore, an opening such as a skylight can be freely formed inside the rectangular frame 40. A skylight can be formed by placing a translucent resin or a glass plate on the upper part of the opening S formed in this way and spreading the periphery with a roofing material.
