Description

  The present invention relates to a column beam connection structure of a unit type building.

  Conventionally, as a kind of building, a unit type building configured by connecting a plurality of building units to each other is known (see, for example, Patent Document 1). In the unit type building, the building unit is configured to include a plurality of columns and a plurality of upper beams and lower beams (large beams) connected to the upper end portion and the lower end portion of the columns. The column is formed of, for example, a square steel pipe, and the upper beam and the lower beam are formed of, for example, a shape steel. Adjacent building units are connected to each other via a connecting member such as a connecting plate. As a connection member, what connects the adjacent pillars of an adjacent building unit, for example is used.

  In a unit type building, there may be a space in the building such as an inner garage or an alcove. In that case, a dedicated building unit for forming an interstitial space may be provided as a building unit. In such a building unit, a part of the lower beam may be removed so as to form an intersoil space, and in this case, a portion left (not removed) in the lower beam becomes a partial beam. Since such a partial beam has one end or both ends not fixed to the column, there is a concern that inconvenience such as misalignment may occur.

  Therefore, it is conceivable to connect such a partial beam to a lower beam of an adjacent building unit provided to face the partial beam via a bracket. If it does so, since a partial beam can be restrained to a lower beam, it becomes possible to suppress the above-mentioned inconvenience. As such a bracket, one having a U-shaped cross section having a pair of opposed plate portions facing each other is conceivable. In that case, it is conceivable that the bracket is disposed between the lower beam and the partial beam, one of the opposing plate portions is fixed to the lower beam, and the other is fixed to the partial beam. At this time, it is conceivable that each counter plate portion is fixed using a bolt and a nut.

JP 2010-174440 A

  Here, depending on the arrangement of the building units constituting the unit type building, the above-mentioned partial beams may be arranged to face the columns of the adjacent building units. In that case, it is conceivable to connect the partial beam to the column via a bracket. If it does so, it will become possible to suppress inconveniences, such as position shift of a partial beam like the above-mentioned case.

  However, since the pillar has a square pillar shape, it is considered impossible to fix the bracket to the pillar with bolts and nuts. That is, when the bracket is fixed to the column with bolts, it is necessary to dispose the nut inside the column, but such a case is considered impossible in practice. Also, if the nut is welded to the inner surface of the column in advance, the bracket can be bolted to the column, but welding the nut to the inner surface of the column is extremely difficult. It is done.

  Instead of the above partial beams, it is also conceivable to connect ordinary lower beams whose both ends are fixed to columns to the columns of adjacent building units by brackets. It is also conceivable to connect the upper beam to the column of the adjacent building unit instead of the lower beam. However, in those cases, the above-mentioned problems can occur as well.

  The present invention has been made in view of the above circumstances, and has a column-beam connection structure for a unit-type building capable of suitably connecting a partial beam or a large beam made of a part of a large beam to a column of an adjacent building unit. The main purpose is to provide it.

  In order to solve the above-mentioned problem, the column-beam connection structure of the unit type building of the first invention has a plurality of columns made of square steel pipes and a plurality of large beams made of shape steel that are respectively connected to the adjacent columns. Applied to a unit-type building constructed by combining a plurality of the building units, the building unit comprising a first unit and a second unit adjacent to each other side by side, One unit is either a partial beam formed by removing a part of the large beam or the large beam, and has an opposing beam provided to face the column of the second unit, The column facing the counter beam in the second unit is a counter column, and includes a connection bracket that connects the counter beam to the counter column, and the connection bracket includes the pair A beam fixing plate portion fixed by a first fixing tool to a surface of the beam facing the counter column, and a column fixing fixed by a second fixing tool to a side surface of the counter column orthogonal to the facing surface of the counter beam. The column fixing plate portion is fixed to the counter column by screwing the second fixing tool into the counter column via the column fixing plate unit.

  According to the present invention, in the first unit and the second unit adjacent to each other side by side, the partial beam or the large beam (opposing beam) of the first unit is arranged to face the column (opposing column) of the second unit. In the arrangement state, the opposed beam of the first unit is coupled to the opposed column of the second unit via a coupling bracket. The connecting bracket has its beam fixing plate portion fixed to the opposing beam by the first fixture, and its column fixing plate portion fixed to the opposing column by the second fixture. In this case, the column fixing plate portion is fixed (one side) by screwing the second fixing tool into the counter column via the column fixing plate portion, so that the column fixing plate portion is fixed to the inside of the counter column. There is no need to provide a fixture such as a nut. Therefore, it becomes possible to easily fix the column fixing plate portion to the opposing column having a square cylindrical shape. In addition, as a 2nd fixing tool, a tapping screw is mentioned, for example.

  In addition, since the column fixing plate portion is fixed to the side surface orthogonal to the facing surface of the facing column, unlike the case where the column fixing plate portion is fixed to the facing surface of the facing column, the column fixing plate portion is attached to the second fixture. Therefore, the opposing beam does not interfere with the work when the fixing to the opposing column. Therefore, such a fixing operation can be suitably performed. Therefore, in this case, it becomes possible to suitably connect a partial beam or a large beam (opposing beam) made of a part of the large beam to a column (opposing column) of an adjacent building unit.

  The above-described operation of connecting the facing beam to the facing column can be performed from a space (hereinafter referred to as a working space) on the side surface (in other words, the fixing surface of the column fixing plate portion) orthogonal to the facing surface of the facing column. Conceivable.

  The column-beam connection structure of a unit type building of the second invention is the counter plate provided in the first invention, wherein the connection bracket is connected to the column fixing plate portion and is opposed to the opposing surface of the opposing column. And a connecting plate portion that connects the counter plate portion and the beam fixing plate portion, and the connecting plate portion is an end of the counter plate portion opposite to the column fixing plate portion side. The beam fixing plate portion extends from the connecting plate portion toward the same side as the counter plate portion.

  According to the present invention, the connecting bracket is provided with the facing plate portion facing the facing surface of the facing column, and the connecting plate portion connecting the facing plate portion and the beam fixing plate portion. The beam fixing plate portion extends from the connecting plate portion to the same side as the counter plate portion. In other words, the beam fixing plate portion extends from the connecting plate portion toward the work space. In this case, when the beam fixing plate portion is fixed to the opposing beam by the first fixing tool from the work space side, the connecting plate portion does not get in the way, so that the fixing operation can be facilitated. Thereby, it becomes possible to perform the operation | work which connects an opposing beam to an opposing column more suitably.

  The column-beam connection structure of a unit type building according to a third invention is characterized in that, in the second invention, the opposing plate portion is disposed in contact with the opposing surface of the opposing pillar.

  According to the present invention, in the connecting bracket, in addition to the column fixing plate portion being in contact (fixed) with the side surface orthogonal to the facing surface of the facing column, the facing plate portion is placed on the facing surface (side surface) of the facing column. It is in contact. In this case, since the connecting bracket is disposed in contact with two mutually orthogonal side surfaces of the opposing column, the connecting bracket can be stably fixed to the opposing column. Thereby, the connection state of the opposing beam with respect to the opposing column via the connection bracket can be stabilized.

  In the column-beam connection structure of a unit type building according to a fourth aspect of the present invention, in any one of the first to third aspects, the opposing beam is the partial beam whose both ends are not fixed to the column. Features.

  As a partial beam formed by removing a part of a large beam, there is a beam whose both ends are not fixed to a column. It is considered that such partial beams are likely to be displaced. In that respect, in the present invention, since such a partial beam (opposing beam) is connected to the opposing column via a connecting bracket, the partial beam can be preferably restrained, and its positional deviation can be suppressed. Become.

  According to a fifth aspect of the present invention, in the united building column beam connection structure, in the fourth invention, the partial beam is formed by removing a part of the lower beam as the large beam, and is formed inside the first unit. A plurality of inter-soil spaces are formed side by side in the longitudinal direction of the lower beam, and the partial beams are formed by removing portions corresponding to the inter-soil spaces in the lower beam, respectively. And

  When a plurality of inter-soil spaces are formed in the first unit in the longitudinal direction of the lower beam, it may be considered that portions corresponding to the inter-soil spaces are removed from the lower beam. In that case, the above-mentioned portions of the lower beam are removed, so that a partial beam whose both ends are not fixed to the column is formed. It is conceivable that various members such as a partition wall part that partitions the inter-soil space are fixed to the partial beam formed of a part of the lower beam. Therefore, it is particularly required to suppress the positional deviation. In that respect, in the present invention, since the partial beam is connected to the opposing column via the connection bracket, the positional deviation can be suitably suppressed.

  According to a sixth aspect of the present invention, in the united building column beam connection structure, in the fifth invention, the first unit is provided with a partition wall portion that partitions the inter-soil spaces, and the floor portion of the first unit. Is provided between the partial beam and a lower beam provided to face the partial beam, with a support beam extending along the partition wall portion and supporting the partition wall portion. It is characterized by that.

  According to the present invention, the first unit is provided with the partition wall portion that partitions the plurality of dirt spaces, and the support beam that supports the partition wall portion is bridged between the partial beam and the lower beam facing the partial beam. Has been. In this case, since the load of the partition wall portion acts on the partial beam via the support beam, it is strongly required to dispose the partial beam in a stable state. In this respect, according to the present invention, since the partial beam is connected to the opposing column via the connection bracket, the binding force of the partial beam can be increased, and as a result, the partition wall portion can be stably maintained. It becomes possible to support.

  According to a seventh aspect of the present invention, in the united building column beam connection structure, in the sixth invention, the partition wall portion includes a plurality of wall panels provided side by side, the wall panel including a wall surface material and a wall surface thereof. A wall base material provided on the back side of the material, and among the plurality of wall panels, the wall base material arranged at the end on the second unit side is fixed to the partial beam. It is characterized by.

  According to this invention, the wall base material is being fixed to the partial beam about the wall panel arrange | positioned at the edge part by the side of the 2nd unit among the some wall panels which comprise a partition wall part. In this case, the partial beam is used not only for bridging the support beam, but also as a base material for fixing the wall panel. Therefore, the partial beam can be effectively used.

  The beam fixing plate portion 71 is fixed to the web 35 a of the partial beam 35 by fastening bolts 38 and nuts 39. Bolts 38 (corresponding to the first fixing tool) are respectively inserted into the hole 71a formed in the beam fixing plate 71 and the insertion hole 42 of the web 35a, and welded to the inner surface of the web 35a in the inserted state. It is fastened with a fixed nut 39. Specifically, a plurality of insertion holes 42 are formed in the web 35a along the beam length direction of the partial beam 35 (the same direction as the thickness direction of the partition wall portion 17). More specifically, in the web 35a, a plurality of insertion holes 42 used when the temporary beams 33 and 34 are fixed (temporarily fixed) by the bolts 38 are arranged side by side in the beam length direction. Yes. The beam fixing plate portion 71 is fixed to the web 35 a by the bolt 38 using the insertion hole 42 on the entrance 11 side (communication portion 16 side) among the plurality of insertion holes 42. For example, the bolt 38 removed when the temporary beams 33 and 34 are removed is used as the bolt 38.

  The column fixing plate portion 72 is fixed to the side surface 21b of the column 21X by a plurality of upper and lower (specifically, three) tapping screws 78 (corresponding to a second fixing tool). The column fixing plate portion 72 is fixed at a position closer to the building unit 20B (partial beam 35) than the bracket 91 on the side surface 21b of the column 21X. An insertion hole 79 (in other words, a fixing hole 79) for inserting (fastening) the tapping screw 78 is formed in a side wall portion that forms the side surface 21 b in the column 21 </ b> X. The column fixing plate portion 72 is also formed with an insertion hole 81 for inserting the tapping screw 78. The tapping screw 78 is screwed into the insertion hole 79 of the column 21 </ b> X via the insertion hole 81 of the column fixing plate portion 72. Thereby, the column fixing plate portion 72 is fixed to the side surface 21b of the column 21X.

  The connecting plate portion 73 includes a counter plate portion 74 provided to face the side surface 21a of the column 21X, and a connecting plate portion 75 that connects the counter plate portion 74 and the beam fixing plate portion 71. The counter plate portion 74 is connected to the end of the column fixing plate portion 72 on the building unit 20B (partial beam 35) side, and is disposed in contact with the side surface 21a of the column 21X.

  The connecting plate portion 75 includes an end portion on the outdoor side (in other words, opposite to the entrance 11 side) of the opposing plate portion 74 in the wall thickness direction of the partition wall portion 17 (outer wall portion 24), and beam fixing in the wall thickness direction. The end of the plate portion 71 on the garage 15 side (in other words, the side opposite to the entrance 11 side) is connected. In other words, the connecting plate portion 75 is connected to the end of the counter plate portion 74 opposite to the column fixing plate portion 72 side, and the beam fixing plate portion 71 from the connecting plate portion 75 is on the same side as the counter plate portion 74. That is, it extends toward the entrance 11 side. In this case, the opposing plate portion 74, the connecting plate portion 75, and the beam fixing plate portion 71 are arranged so as to form a U shape in plan view. In addition, the connecting plate portion 75 is disposed at a substantially central portion in the wall thickness direction or closer to the entrance 11 in the facing portion between the column 21X and the partial beam 35.

  The wall thickness direction is the same as the horizontal direction orthogonal to the unit arrangement direction in which the building units 20A and 20B are arranged.

  On the inner side surrounded by the opposing plate portion 74, the connecting plate portion 75, and the beam fixing plate portion 71, a groove portion 76 opened toward the entrance 11 side is formed. In the present embodiment, a wiring K extending vertically inside the partition wall portion 17 (outer wall portion 24) is disposed in the groove portion 76, and the groove portion 76 is used as a space for arranging the wiring K. However, the groove portion 76 may be used for other purposes such as a space for arranging a heat insulating material such as glass wool.

  Further, the connection bracket 70 is disposed at a height position where the upper end of the connection bracket 70 does not protrude above the upper end of the partial beam 35. Specifically, the upper end of the connection bracket 70 is set at the same height as the upper end of the partial beam 35. Thereby, for example, even if members such as floor materials and wall materials are subsequently disposed above the connection bracket 70, it is possible to prevent these members from interfering with the connection bracket 70.

  Of the wall panels 51 constituting the partition wall portion 17, the wall panels 51 arranged adjacent to the outer wall portion 24 (in other words, disposed at the end on the building unit 20 </ b> A side) are fixed to the partial beam 35. Yes. The wall panel 51 has a vertical frame member 83 extending in the vertical direction on the back side of the wall member 54. The vertical frame member 83 is formed of a steel material having an L-shaped cross section, and is disposed closer to the outer wall portion 24 (building unit 20 </ b> A) on the back surface side of the wall surface member 54. The vertical frame member 83 corresponds to a wall base material.

  The vertical frame member 83 includes a wall fixing plate portion 83 a fixed to the back surface side of the wall surface material 54 and a beam fixing plate portion 83 b fixed to the outer surface of the web 35 a of the partial beam 35. The beam fixing plate portion 83 b is fixed to the web 35 a by fastening bolts 38 and nuts 39. The beam fixing plate portion 83b is fixed at a position closer to the garage 15 than the beam fixing plate portion 71 of the connection bracket 70 in the web 35a. In this case, the beam fixing plate portion 71 of the connection bracket 70 and the beam fixing plate portion 83b of the vertical frame member 83 are arranged side by side in the wall thickness direction of the partition wall portion 17 in the web 35a. The bolts 38 are respectively inserted into holes 84 formed in the beam fixing plate portion 83b and the insertion holes 42 of the web 35a, and fastened with nuts 39 that are welded and fixed to the inner surface of the web 35a in the inserted state. ing. Specifically, the beam fixing plate portion 83b is fixed to the bolt 38 using the insertion holes 42 on the garage 15 side (outdoor side) among the plurality of insertion holes 42 provided in the web 35a. Note that the fixing bolt 38 of the temporary beams 33 and 34 is diverted to the bolt 38 as in the case of fixing the beam fixing plate portion 71.

  Next, an operation procedure for connecting the partial beam 35 of the building unit 20B to the column 21X of the building unit 20A will be described with reference to FIG. FIG. 6 is a diagram for explaining the work procedure.

  First, in the manufacturing factory, each building unit 20 constituting the building 10 is manufactured. At this time, the floor girder 23a is temporarily fixed to the floor of the building unit 20A. Of the wall panels 86 constituting the outer wall portion 24 of the building unit 20A, at least the wall panel 86 disposed in the adjacent portion to the partition wall portion 17 is not assembled to the building unit 20A.

  As for the building unit 20B, the floor girder 23X (the floor girder 23X including the temporary beams 33 and 34) is assembled to the floor. Of the wall panels 51 and 52 that constitute the partition wall portion 17 of the building unit 20B, at least the wall panels 51 and 52 that are disposed adjacent to the outer wall portion 24 are not assembled to the building unit 20B.

  After each building unit 20 is manufactured, each building unit 20 is transported to a construction site by a truck or the like.

  At the construction site, each building unit 20 that has been transported from the manufacturing factory is first installed at a predetermined position. After installing each building unit 20, the floor beams 23a are removed from the building unit 20A, and the temporary beams 33 and 34 are removed from the floor beams 23X of the building unit 20B. Thereby, as shown to Fig.6 (a), the partial beam 35 is formed in the floor part of the building unit 20B, and the partial beam 35 and the pillar 21X of the building unit 20A are mutually opposingly arranged. At this time, since the respective wall panels 52 and 86 on the entrance 11 side located at the boundary between the partition wall 17 and the outer wall 24 are not arranged, the partial beam 35 and the column 21X are respectively connected to the entrance 11. Exposed to the side.

  Then, the operation | work which connects the partial beam 35 to the pillar 21X of the building unit 20A using the connection bracket 70 is performed. In this embodiment, it is assumed that this connection work is performed from the entrance 11 (corresponding to a work space) side. In this connection operation, first, as shown in FIG. 6B, the connection bracket 70 is disposed at the opposing portion of the partial beam 35 and the column 21X, and the beam fixing plate portion 71 is connected to the partial beam by the bolt 38 and the nut 39. It fixes to 35 webs 35a. Specifically, a hand is inserted into the groove portion 76 of the connecting bracket 70 from the entrance 11 side, and the fixing work with the bolt 38 is performed.

  Subsequently, as shown in FIG. 6C, the column fixing plate portion 72 of the connection bracket 70 is fixed to the side surface 21 b of the column 21 by the tapping screw 78. Thereby, the partial beam 35 is connected to the column 21 </ b> X via the connection bracket 70.

  Thereafter, as shown in FIG. 6 (d), the remaining wall panel 86 (the wall panel 86 disposed adjacent to the partition wall 17) is assembled to the building unit 20A, and the remaining wall panel is mounted to the building unit 20B. 51 and 52 (wall panels 51 and 52 arranged in the adjacent part to the outer wall part 24) are assembled.

  As mentioned above, according to the structure of this embodiment explained in full detail, the following outstanding effects are acquired.

  The partial beam 35 of the building unit 20B was arranged to face the column 21X of the building unit 20A, and the partial beam 35 was connected to the column 21X via the connection bracket 70 in the arrangement state. The connection bracket 70 includes a beam fixing plate portion 71 fixed to the partial beam 35 by a bolt 38 (corresponding to a first fixing tool) and a tapping screw 78 (corresponding to a second fixing tool) to the column 21X. A column fixing plate portion 72 to be fixed is provided. The fixing with the tapping screw 78 does not require the use of nuts unlike the fixing with bolts. In this case, the column fixing plate portion 72 can be easily fixed to the square cylindrical column 21X.

  Further, since the column fixing plate portion 72 is fixed to the side surface 21b on the entrance 11 side of the column 21X, in other words, the side surface 21b orthogonal to the surface (side surface 21a) facing the partial beam 35 in the column 21X, the column fixing plate portion 72 is fixed to the column 21X. Unlike the case of fixing to the side surface 21a of 21X, when the column fixing plate portion 72 is fixed to the column 21X by the tapping screw 78, the partial beam 35 does not interfere with the work. Therefore, such a fixing operation can be suitably performed. Therefore, in this case, the partial beam 35 (from the entrance 11 side) can be suitably connected to the column 21X of the adjacent building unit 20A.

  The connection bracket 70 is provided with a counter plate portion 74 provided to face the side surface 21a (corresponding to the counter surface) of the column 21X, and a connecting plate portion 75 that connects the counter plate portion 74 and the beam fixing plate portion 71. The beam fixing plate portion 71 is formed so as to extend from the connecting plate portion 75 toward the same side as the counter plate portion 74, that is, toward the entrance 11 (corresponding to a work space). In this case, when the beam fixing plate portion 71 is fixed to the partial beam 35 by the bolt 38 from the entrance 11 side, the connecting plate portion 75 does not get in the way, so that the fixing operation can be facilitated. Thereby, it becomes possible to perform the operation | work which connects the partial beam 35 to the pillar 21X more suitably.

  In addition to contacting (fixing) the column fixing plate portion 72 to the side surface 21b of the column 21X in the connecting bracket 70, the counter plate portion 74 was brought into contact with the side surface 21a of the column 21X. In this case, since the connecting bracket 70 is arranged in contact with the two side surfaces 21a and 21b orthogonal to each other in the column 21X, the connecting bracket 70 can be fixed to the column 21X in a stable state. Thereby, the connection state of the partial beam 35 with respect to the column 21X via the connection bracket 70 can be stabilized.

  It is conceivable that the partial beam 35 whose both ends are not fixed to the column 21 is likely to be displaced. In that respect, since the partial beam 35 is connected to the column 21X via the connection bracket 70, the partial beam 35 can be preferably restrained, and the displacement can be suppressed.

  The building 11B has a structure in which the entrance 11 and the garage 15 are formed in the longitudinal direction of the floor beam 23X (in other words, the unit arrangement direction) inside the building unit 20B. The partial beams 35 were formed by removing portions corresponding to (specifically, temporary beams 33 and 34). Various members such as the partition wall 17 that partitions the entrance 11 and the garage 15 are considered to be fixed to a part to the partial beam 35 of the large floor beam 23X. Especially required. In this respect, since the partial beam 35 is connected to the column 21X via the connection bracket 70, the positional deviation can be suitably suppressed.

  A floor beam 26a that extends along the partition wall portion 17 and supports the partition wall portion 17 is provided between the partial beam 35 and the floor large beam 23 facing the partial beam 35. In this case, since the load of the partition wall portion 17 acts on the partial beam 35 via the floor beam 26a, it is strongly required to arrange the partial beam 35 in a stable state. In this respect, since the partial beam 35 is connected to the column 21X via the connection bracket 70, the restraining force of the partial beam 35 can be increased, and as a result, the partition wall portion 17 can be supported in a stable state. .

  The vertical frame member 83 of the wall panel 51 disposed at the end on the building unit 20 </ b> A side among the plurality of wall panels 51 constituting the partition wall portion 17 is fixed to the partial beam 35. In this case, since the partial beam 35 is used not only for bridging the floor beam 26a but also as a base material for fixing the wall panel 51, the partial beam 35 can be effectively used.

  The present invention is not limited to the above embodiment, and may be implemented as follows, for example.

  (1) The shape of the connection bracket 70 is not necessarily limited to that of the above embodiment. For example, the connecting bracket may be formed in an L shape having two plate portions orthogonal to each other. In this case, one of the two plate portions (corresponding to the beam fixing plate portion) is fixed to the web 35a of the partial beam 35, and the other plate portion (corresponding to the column fixing plate portion) is fixed to the side surface 21b of the column 21X. What is necessary is to fix to. Even in this case, the partial beam 35 can be suitably connected to the column 21X.

  (2) In the above embodiment, the opposing plate portion 74 of the connecting bracket 70 is brought into contact with the side surface 21a of the column 21X, but the opposing plate portion 74 may not be brought into contact with the side surface 21a. That is, a predetermined gap may be provided between the counter plate portion 74 and the side surface 21a.

  (3) In the above embodiment, the column fixing plate portion 72 of the connection bracket 70 is fixed to the side surface 21b on the entrance 11 side among the two side surfaces orthogonal to the side surface 21a (the surface facing the partial beam 35) in the column 21X. Instead of this, the column fixing plate portion 72 may be fixed to the side surface on the outdoor side (the side surface facing the side surface 21b). In that case, what is necessary is just to perform the operation | work which connects the partial beam 35 to the pillar 21X from the outdoor side (garage 15 side). However, in this case, some wall panels 85 on the outdoor side (the garage 15 side) of the wall panels 85 of the building unit 20A adjacent to the partition wall 17 are not assembled to the building unit 20A. It is necessary to keep in.

  (4) In the above embodiment, the entrance 11 and the garage 15 are provided in the building unit 20B as a plurality of dirt spaces arranged in the unit longitudinal direction (longitudinal direction of the floor beam 23X). The combination of the entrance 11 and the garage 15 is not necessary. For example, it is conceivable to use an alcove instead of the garage 15 or a dirt instead of the entrance 11. Further, any of the plurality of dirt spaces may be a garage.

  Moreover, in the said embodiment, although the entrance 11 was formed ranging over each building unit 20A, 20B, it replaces with this and you may make it form the entrance 11 only in the building unit 20B (adjacent part 29). .

  (5) In the above embodiment, the partial beams 35 whose both ends are not fixed to the columns 21 are connected to the columns 21X of the building unit 20A by the connection bracket 70, but only one end is not fixed to the columns 21 (in other words, A cantilevered partial beam (fixed to the column 21 only at one end) may be coupled to the column 21X by the coupling bracket 70. Even in such a case, such a cantilevered partial beam can be constrained to the column 21 </ b> X, so that the positional deviation of the partial beam can be suitably suppressed.

  Further, not only the partial beams but also the large floor beams 23 whose both ends are fixed to the columns 21 may be coupled to the columns 21X by the coupling brackets 70. In that case, the restraining force of the floor girder 23 can be increased.

  (6) In the above embodiment, the partial beam 35 formed by removing a part (temporary beams 33, 34) of the large floor beam 23X (lower beam) is connected to the column 21X by the connection bracket 70. The partial beam on the ceiling side formed by removing a part of the large beam 22 (upper beam) may be connected to the column 21X. It is conceivable that a part of the ceiling beam 22 is also removed when, for example, an atrium space extending over the upper and lower floors is formed in the building. In this case, a partial beam is also formed. Therefore, in such a case, the connection structure of the present invention may be applied to such a ceiling-side partial beam.

  (7) In the above embodiment, the case where the floor girder 23 is formed of channel steel has been described, but the case where the floor girder 23 is formed of other shape steel such as H-shaped steel or square steel is also described. Similarly, the present invention can be applied.

  (8) In the above embodiment, the bolt 38 is used as the first fixture, but other fixtures such as a tapping screw or a screw may be used as the first fixture. Moreover, in the said embodiment, although the tapping screw 78 was used as a 2nd fixing tool, you may use other fixing tools, such as a one side bolt and a self tapping screw. When a self-tapping screw is used as the second fixing tool, it is not necessary to provide the insertion hole 79 in the column 21X in advance, and the insertion hole may be formed in the column 21X while screwing the self-tapping screw.
