Description

  The present invention relates to a unit building.

  The following Patent Document 1 discloses a technique related to an installation structure of a unit type building and an installation method thereof. To explain briefly along the construction procedure, first, a pair of building units each assembled in a rectangular parallelepiped shape with multiple columns and beams are adjacent so that the upper beams of both building units are arranged in a straight line (See FIG. 4 of Patent Document 1). One building unit is provided with an additional pillar in advance at a location away from the opening. Next, the outer wall panel unit including the entrance portion and the outer wall panel portion is attached to the outer wall portions of the pair of building units (see FIG. 6 of Patent Document 1).

  Next, an elongated reinforcing beam is disposed along the upper beam of the pair of building units, and is attached to the upper beam via a joining member attached to the upper end of the building unit. It is attached also to the upper end part of an outer wall panel part (refer FIG. 7 of patent document 1). Then, the pillar which opposes parts other than the edge part of a reinforcement beam among the pillars of a pair of building unit is removed (refer FIG. 8 of patent document 1). Thereby, the opening part larger than the opening part formed between the pillars of one building unit is formed in the side surface of a pair of building units. Even if the two opposing pillars are removed, the reinforcement beam is provided along the upper beam arranged in a straight line and the additional pillar is installed, so that the rigidity of the building unit is maintained. That's it.

JP 2014-43753 A

  However, according to the prior art, the workability is poor because the reinforcing beam and the outer wall panel unit are separately attached. Further, since the above-described reinforcing beam is attached not only to the upper beam of the pair of building units via the joining member but also to the outer wall panel unit side, the outer wall panel unit itself is reinforced. For this reason, finally, when a pair of opposing columns is removed, a burden is placed on the column omission frame, and the structure becomes unreasonable, and an additional column is required.

  In consideration of the above problems, the present invention efficiently reinforces a column omission part when a plurality of building units including a column omission part are assembled with a reinforcing body with an outer wall having an opening overlapping the column omission part. In addition, an object is to obtain a unit building that can improve workability in a building site.

  The unit building according to claim 1 is a pair of temporary buildings in which a plurality of columns, a plurality of ceiling beams, and a plurality of floor beams are assembled into a rectangular parallelepiped shape, and at least one column is removable. The building units are arranged adjacent to each other so that the temporary columns are adjacent to each other, and the building unit group is provided with a column omitting portion in which a pair of the temporary columns are removed, and linearly passes through the column omitting portion. A reinforcing body including a reinforcing beam arranged along a pair of arranged ceiling beams, and a pair of columns supporting both ends of the reinforcing beam, and the column omission portion as viewed from the outdoor side And an outer wall panel fixed to the reinforcing body, and the reinforcing beam with the outer wall installed on the outer wall surface of the building unit group by joining the reinforcing beam to the ceiling beam And having a body.

A building unit group is configured by being arranged adjacent to the. In this building unit group, a column omission portion is formed by removing a pair of temporary columns. And the reinforcement body with an outer wall provided with the reinforcement body and the outer wall panel is installed in the outer wall surface by the side of the column omission part of the said building unit group.

  Here, the reinforcing body includes a reinforcing beam arranged along a pair of ceiling beams arranged in a straight line through the column omission portion, and a pair of columns supporting both ends of the reinforcing beam. It consists of Furthermore, the reinforcing beam of the reinforcing body is joined to the ceiling beam. For this reason, the load applied to the column omitted portion is also supported by the pair of support columns via the reinforcing beam. Thereby, the support strength of a column omission part is improved. In other words, the column omission portion can be reinforced efficiently.

  In addition, because the outer wall panel is fixed to the reinforcing beam of the reinforcing body, in the building area, the reinforcing beam of the reinforcing body with the outer wall is simply joined to the ceiling beam of the building unit on the side of the building unit including the column omitted part. Well, there is no need to attach the reinforcement and the outer wall panel separately. That is, the number of parts is reduced by integrating the reinforcing beam and the outer wall panel. For this reason, the workability | operativity in a building site is improved by the part number of parts reduced. Moreover, since the reinforcing beam which comprises a reinforcement body is supported by the support | pillar, the reinforcement body with an outer wall can be made to stand independently so that a building unit may be opposed, and a building unit and the reinforcement body with an outer wall can be positioned.

Two attachment holes 58 </ b> A are formed in the back surface portion 54 along the longitudinal direction (height direction) of the back surface portion 54, and two pieces of attachment holes 58 </ b> A are formed in the ceiling beam 26 along the formation direction of the ceiling beam 26. A mounting hole 58B is formed. Then, the shaft portion of the bolt 60 is inserted from each mounting hole 58B toward the corresponding mounting hole 58A and fastened with a nut 62. The nut 62 is a weld nut. Thereby, each bracket 52 is being fixed with respect to the ceiling large beam 26 at two places along the formation direction (vertical direction) of the ceiling large beam 26 (refer FIG. 3 (B)).

  On the other hand, the front-end | tip part of a pair of side wall 55 which comprises the bracket 52 is inserted by the groove part 64 which is the inner space of the reinforcement beam 46 arrange | positioned facing (refer FIG.3 (C)). As shown in FIG. 3A, the portion where the tip of the bracket 52 and the reinforcing beam 46 overlap in a plan view is joined by arc welding or the like.

  As shown in FIG. 3C, in a state where the reinforcing beam 46 is joined to the ceiling large beam 26 arranged on the side faces 12A and 14A via the bracket 52, the horizontal position of the upper end portion of the reinforcing beam 46 is the ceiling. It arrange | positions so that it may become substantially the same as the horizontal position of the upper end part of the big beam 26. FIG. In other words, the upper end portion of the reinforcing beam 46 does not protrude above the upper end portion of the ceiling beam 26.

  On the other hand, the floor beam 50 that constitutes the lower edge of the reinforcing body 42 is also disposed along the large floor beam 30 that passes through the column omitting portion P and is disposed on the end faces 12A and 14A of the respective building units 12 and 14. . In the present embodiment, the bracket 52 is not disposed between the floor beam 50 and the floor beam 30. Therefore, the floor beam 50 is not fixed to the floor beam 30. In addition, it is good also as a structure by which the floor beam 50 is attached to the floor large beam 30 arrange | positioned on the wife side surfaces 12A and 14A via the bracket 52 similarly to the relationship between the reinforcement body 42 and the ceiling large beam 26 mentioned above.

  As described above, the height dimension of the pair of support columns 48 is substantially the same as the height dimension of the pillars 16 of the building units 12 and 14. Moreover, the upper end part of a pair of support | pillar 48 is being fixed to the both ends of the reinforcement beam 46, respectively, and the lower end part of a pair of support | pillar 48 is being fixed to the both ends of the floor beam 50, respectively (refer FIG. 2). As an example, the connection between both ends of the reinforcing beam 46 and the upper end of the column 48 is as follows. A rectangular flat plate-shaped joining bracket is welded in advance to the longitudinal end portion of the reinforcing beam 46, and the end portion of the joining bracket protruding from the longitudinal end portion of the reinforcing beam 46 is used as the indoor side surface of the column 48. And are bolted at a plurality of upper and lower points. The connection between the both ends of the floor beam 50 and the lower end of the column 48 is the same. Thereby, both ends of the reinforcing beam 46 and the floor beam 50 are supported by the pair of columns 48. Then, as shown in FIG. 2, when the reinforcing body 42 is self-supported so as to face the end faces 12A and 14A of the building units 12 and 14, the outer side surface of each ceiling beam 26 and the groove portion 64 of the reinforcing beam 46 are formed. Opposed to each other. In other words, the pair of columns 48 also has a positioning function for positioning the reinforcing beam 46 at a position facing the ceiling beam 26. In addition, the cross-sectional shape in the horizontal direction of each support | pillar 48 is made into the substantially U shape opened to the outdoor side.

  Here, the principal part enlarged plan view which shows the assembly | attachment state of the building units 12 and 14 and the reinforcement body 40 with an outer wall is shown by FIG. As shown in this figure, in a state where the reinforcing beam 46 is fixed to the ceiling beam 26, a predetermined gap 66 is provided in the wall thickness direction due to the bracket 52 interposed between the ceiling beam 26 and the reinforcing beam 46. Is formed. For this reason, the reinforcing beam 46 is arranged offset to the outdoor side with respect to the end faces 12A and 14A of the building units 12 and 14. That is, the bracket 52 also has a function of determining an offset amount for separating the reinforcing beam 46 from the ceiling beam 26.

  On the other hand, as shown in FIGS. 2 and 4, the outer wall panel 44 forms a design surface of the outer wall surface 36 of the unit building 10 and is fixed to the reinforcing body 42 via a plurality of outer wall frames 68. It consists of multiple panels. The outer wall panel 44 includes a substantially rectangular opening 70 (see FIGS. 1 and 2) in the center when viewed from the front, and forms a substantially rectangular frame. When the outer wall panel 44 is attached to the reinforcing body 42, the entire reinforcing body 42 is covered with the outer wall panel 44 in a front view.

  Further, as shown in FIGS. 1 and 2, the opening 70 is viewed from the outdoor side of the unit building 10 when the reinforcing body 40 with the outer wall is assembled to the end faces 12A and 14A of the building units 12 and 14. Thus, it is formed at a position overlapping the column omission portion P.

  As shown in FIG. 5, in the state where the outer wall panel 44 is assembled to the reinforcing body 42, the upper end portion of the outer wall panel 44 is fixed to the outer surface of the reinforcing beam 46, and the lower end portion of the outer wall panel 44 is the floor beam 50. It is fixed to the outside surface. The opening 70 is provided with a sweep window 72. A sash 74 constituting the sweep window 72 is attached to the periphery of the opening 70, and two window members are slidable on the sash 74. 76 is supported.

  As shown in this figure, the horizontal position of the upper end portion of the outer wall panel 44 is arranged at substantially the same horizontal position as the upper end portion of the reinforcing beam 46. Therefore, like the reinforcing beam 46, the upper end portion of the outer wall panel 44 does not protrude upward from the upper end portion of the ceiling large beam 26. Further, the upper end portion 70 </ b> A of the opening 70 is disposed below the lower end portion of the reinforcing beam 46. Therefore, an extra length space K (region indicated by a one-dot chain line in FIG. 5) is formed below the reinforcing beam 46 in a range from the lower end portion of the reinforcing beam 46 to the upper end portion 70A of the opening 70. . Thereby, for example, the cross-sectional size of the reinforcing beam 46 can be increased as necessary, or a flat additional reinforcing beam or the like is joined to the lower end of the reinforcing beam 46 and extended below the reinforcing beam 46. Can do. As a result, the cross section of the reinforcing beam can be adjusted and the strength of the reinforcing beam can be optimized. In the present embodiment, the lower end portion 70B of the opening portion 70 is disposed at substantially the same horizontal position as the upper end portion of the floor beam 50, but depending on the type of window formed in the opening portion 70, the lower end portion 70B The height relationship between the upper portion of the portion 70B and the floor beam 50 can be freely set.

(How to assemble unit buildings)
Next, a method for assembling the unit building 10 according to the first embodiment will be described.

  First, in the unit building 10 which concerns on 1st Embodiment, the building units 12 and 14 of the state provided with the temporary column 18 previously, and the reinforcement body 40 with an outer wall are each assembled at the factory beforehand. Then, the building units 12 and 14 are carried into the construction site by the transport vehicle. At this time, the reinforcing body 40 with the outer wall is temporarily fastened to the girder side surface of the building unit 12 or the building unit 14 (the side surface of the building unit 12 or the building unit 14 including the ceiling beam 24 and the floor beam 28). The unit is brought into the building site. First, the first floor portion is constructed using a crane (not shown). Specifically, the building units 12 and 14 with the temporary pillars 18 attached thereto are installed on a foundation (not shown). At this time, the building units 12 and 14 are arranged in parallel in the wife direction, and the ceiling beams 26 arranged on the wife side surfaces 12A and 14A are installed in a straight line. In addition, the temporary columns 18 in the building units 12 and 14 are installed so as to be adjacent at the center.

  Next, the reinforcing body 40 with the outer wall assembled in advance in the factory is attached to the end faces 12A and 14A of the building units 12 and 14 in which the large openings 34 including the column omitted portions P are formed. Specifically, the reinforcing body 40 with the outer wall is suspended by a crane (not shown) so that the side faces 12A and 14A of the building units 12 and 14 already installed on the foundation (not shown) face the reinforcing body 42. The positioning of the large ceiling beam 26 and the reinforcing beam 46 of the building units 12 and 14 is performed by allowing the reinforcing body 40 with the outer wall to stand on a foundation (not shown). Further, using the bracket 52 described above, an offset amount for separating the reinforcing beam 46 from the ceiling beam 26 is set to a predetermined amount. Specifically, the back surface portion 54 of the bracket 52 is brought into contact with the outer surface of the web of the ceiling beam 26 in a state where the bolt insertion holes are positioned so as to be coaxial. Thereafter, the bolt 60 is fastened to the nut (weld nut) 62. Thereafter, each temporary pillar 18 is removed from the building units 12 and 14.

  In this way, the required number of building units 12 and 14 are sequentially installed on a foundation (not shown), the outer wall reinforcing body 40 is assembled, and the temporary pillar 18 is removed, so that the basic structure of the first floor portion of the unit building 10 is obtained. Assembly work is completed.

(Function and effect)
Next, functions and effects of the unit building 10 according to the present embodiment will be described.

  In the unit building 10 constructed as described above, the load applied to the column omitting portion P is distributed and supported on the building units 12 and 14 side and the reinforcing body 42 side. That is, the load applied to the column omitting portion P is not only supported by the pair of columns 16 disposed at the end portions via the ceiling large beams 26 of the building units 12 and 14 but also via the reinforcing beams 46 of the reinforcing body 42. Also supported by the pair of support columns 48. Therefore, the column omission portion P is efficiently reinforced so that the load applied to the column omission portion P can be dispersed and supported by the reinforcing beams 46 and the columns 48 of the reinforcing body 42, and thus the economy of the building units 12 and 14. Design becomes possible.

  Moreover, since the outer wall panel 44 is being fixed to the reinforcement body 42, in the building area, the reinforcement beam 46 of the reinforcement body 40 with an outer wall is provided in the building units 12 and 14 on the side surface of the building units 12 and 14 including the column omission part P. The reinforcing body 42 and the outer wall panel 44 need not be separately attached. That is, the number of parts is reduced by integrating the reinforcing body 42 and the outer wall panel 44. For this reason, the workability | operativity in a building site is improved by the part number of parts reduced. Further, since the reinforcing beam 46 constituting the reinforcing body 42 is supported by the support column 48, the reinforcing body 40 with the outer wall is self-supported so that the end faces 12A and 14A of the building units 12 and 14 and the reinforcing body 42 face each other. Only by doing so, the joint portion (joint portion of the bracket 52) between the ceiling large beam 26 and the reinforcing beam 46 is positioned. This also improves the assembly workability in the building area.

  As a result, according to the present embodiment, when assembling the outer wall panel 44 having the opening 70 that overlaps the column omission portion P to the plurality of building units 12 and 14 including the column omission portion P, the column omission portion P can be efficiently reinforced and workability in a building site can be improved.

  Further, in this embodiment, since the support member (outer wall frame 68) that supports the outer wall panel 44 is integrally attached to the reinforcing body 42, the outer wall panel 44 does not have the column omitting portion P shown in FIG. It can be set as the structure similar to the outer wall panel 45 attached to the side surface of the building unit 12. FIG. Thereby, the versatility of the outer wall panel 44 can be improved.

  Furthermore, in the unit building 10 according to the first embodiment, when transporting from the factory to the building site, the building unit 12 and the building unit 14 are temporarily fixed to the building unit 12 or the building unit 14 to temporarily reinforce the building unit and the building with the outer wall. The body 40 can be transported together. As a result, the conveyance efficiency is improved, and as a result, the construction cost can be significantly reduced.

  Further, in the unit building 10 according to the present embodiment, as shown in FIG. 5, the upper end portion of the reinforcing beam 46 and the outer wall panel in the state where the outer wall reinforcing body 40 is assembled to the building unit 12, 14. The upper end of 44 does not protrude above the upper end of the ceiling beam 26. For this reason, when installing another structure on the building units 12 and 14, the reinforcement body 40 with an outer wall does not become obstructive. That is, the restrictions which the reinforcement body 40 with an outer wall gives to the upper floor member of the building units 12 and 14 can be suppressed. As a result, according to this embodiment, the freedom degree of design of the structure provided in the upper part of the building units 12 and 14 with which the reinforcement body 40 with the outer wall was joined can be raised. In other words, it can be said that the outer wall-attached reinforcing body 40 is highly versatile.

  For example, when two building units in which the column omission part P is formed (installed) on the upper floor portion of the building units 12 and 14 are stacked (stacked), the building unit on the upper floor side (12 14) Even if the reinforcement body (40) with the outer wall is assembled to 14), it does not interfere with the reinforcement body 40 with the outer wall assembled to the building units 12 and 14 on the lower floor side. For this reason, the freedom degree of the layout of the opening part 70 of the lower floor part in the unit building 10 and the opening part (70) of an upper floor part increases, and the intensity | strength of the whole building can be ensured appropriately. Furthermore, if a gate-shaped reinforcement body with an outer wall without floor beams is used as in the second embodiment to be described later, the large floor beams (30) of the building units (12, 14) on the upper floor side can be simply omitted. it can. For this reason, when the entrance part is formed in the building unit (12, 14) on the upper floor side, the striking floor of the entrance part is constrained by the floor beam (30) to a position one step lower than the floor surface of the living space on the same floor. It becomes easy to form without receiving.

  In addition, since the horizontal position of the upper end of the reinforcing beam 46 does not reach the horizontal position of the floor beam of the upper floor building unit, a balcony having a cantilever structure is connected to the floor beam of the upper floor building unit. Will also be possible.

  In the present embodiment, as shown in FIG. 5, the lower end portion of the reinforcing beam 46 is disposed above the upper end portion 70 </ b> A of the opening 70 of the outer wall panel 44. The extra length space K is formed. For this reason, it is possible to extend the lower end of the reinforcing beam 46 to the upper end portion 70A of the opening to increase the size of the reinforcing beam 46 or to arrange an additional reinforcing beam. For this reason, an optimal reinforcement beam cross section can be maintained according to the load burden of the column omission part P of the building units 12 and 14. That is, the strength and rigidity of the reinforcing beam can be optimally adjusted according to the structure design.

  Furthermore, in this embodiment, as shown in FIGS. 4 and 5, the reinforcing beam 46 is joined to the ceiling beam 26 via the bracket 52, so that the reinforcing beam 46 and the existing ceiling beam 26 are connected. Spatial margins (gap 66) are generated, and excessive details can be avoided. Thereby, the thickness of the reinforcing beam 46 can be expanded in the wall thickness direction. For example, it becomes possible to configure the reinforcing beam 46 as a light-duty steel having the same beam cross section as that of the ceiling large beam 26, and to make the reinforcing beam 46 the existing ceiling large beam 26, and to share it as a standard detail. Is also possible.

  Further, if this is grasped from another viewpoint, the reinforcing body 40 with the outer wall interferes with the pillars 16 of the building units 12 and 14 by joining the reinforcing body 40 with the outer wall to the ceiling beam 26 via the plurality of brackets 52. Assembling work can be carried out without making it. As a result, it is possible to increase the degree of freedom of the construction plan in the building area. For example, even after the separate units are arranged on the left and right and top and bottom of the building unit 12 and the pillars 16 of the building units are connected to each other, the assembly work of the reinforcing member with the outer wall can be easily performed.

  Further, the reinforcing beam 46 is offset outward with respect to the side surface including the column omitting part P of the building units 12 and 14, so that the outer wall panel 44 is also offset outward. As a result, the gap 66 between the building units 12 and 14 and the outer wall panel 44 is widened, so that the indoor space can be expanded.

  As described above, according to the present embodiment, the configuration in which the reinforcing body 40 with the outer wall is joined to the ceiling beam 26 via the plurality of brackets 52 is adopted. The construction plan can be rationalized and the indoor space can be expanded by expanding the degree of freedom of assembly timing (flexibility).

  Further, in the present embodiment, as shown in FIG. 3B, the bracket 52 for fixing the reinforcing beam 46 is fixed at two locations along the direction of the ceiling large beam 26. The torsional rigidity of the integrated ceiling beam 26 can be improved. Thereby, when a front door is provided in the opening 70 of the outer wall panel 44, sufficient rigidity can be maintained even if a cantilevered ridge is provided on the reinforcing beam 46 at the top of the front door (for this configuration). This will be described in detail in a second embodiment described later). In addition, it is possible to increase the degree of freedom of the attached space, for example, by making the ceiling surface on the building unit 12, 14 side in a state where the cantilever structure is attached.

  Furthermore, according to the present embodiment, the following effects can be obtained in addition to the above. It is also possible to attach an indoor inner wall or heat insulating material or an opening member (sash) to the indoor side surface of the reinforcing body 40 with the outer wall. For this reason, by assembling the inner wall or the like in advance to the reinforcing body 40 with the outer wall, the workability at the site is further improved. Further, even if the inner wall or the like is previously assembled to the reinforcing body 40 with the outer wall in this way, there is a space between the reinforcing beam 46 of the reinforcing body 40 with the outer wall and the large ceiling beam 26 of the building units 12, 14. It does not interfere with the constituent members of the units 12 and 14, and this point also contributes to improvement in workability.

(Second Embodiment)
Hereinafter, the unit building 110 according to the second embodiment will be described with reference to FIGS. 6 and 7. In addition, about the same component as 1st Embodiment mentioned above, the same number is attached | subjected and the description is abbreviate | omitted.

  As shown in FIG. 6, in the second embodiment, in the building units 12 and 14, the floor beams 28 and 30 of each unit orthogonal to the lower end of the temporary column 18 are omitted, and the building units 12 and 14 The wife side surfaces 12A and 14A are formed with a large opening 111 having a substantially gate shape when viewed from the front, and the gate-side reinforcing member 112 with an outer wall is assembled to the wife side surfaces 12A and 14A when viewed from the front. There is a feature in the point.

  As shown in this figure, in the building units 12 and 14 of the second embodiment, in addition to the column omitting portion P, the floor beams 28 and 30 orthogonal to the lower ends of the respective temporary columns 18 are omitted. Yes. In the building units 12 and 14, a floor surface 120 (see FIG. 7) such as a front door is formed on the indoor side of the building units 12 and 14 without providing a floor beam between the long side floor beams 28. Yes.

  Supplementally, the floor surface formed inside the building unit is usually formed by fixing a floor plate or the like to a floor base and a floor board or the like. On the other hand, the floor surface 120 of the building units 12 and 14 of the present embodiment is assumed to be used as a floor surface such as a front door, so the floor surface position is set lower than that of a normal building unit. It is constructed so that there is almost no difference in height from the floor of the entrance porch that leads to the outdoor side.

  On the other hand, the reinforcing body 114 includes a reinforcing beam 46 and a pair of support columns 48. The upper ends of the columns 48 are joined to both ends of the reinforcing beam 46 in the wife direction, and the reinforcing beams 46 are supported by the pair of columns 48. Therefore, the reinforcing body 114 is configured as a substantially gate shape when viewed from the front. In other words, the reinforcing body 114 of the second embodiment is obtained by omitting the floor beam 50 in the reinforcing body 42 of the first embodiment. Then, a substantially gate-shaped outer wall panel 116 is attached from the outdoor side so as to cover the reinforcing body 114 as viewed from the front, and a substantially portal-shaped reinforcing body 112 with an outer wall is configured as a whole.

  In addition, a rectangular opening 118 opened vertically downward is formed inside the substantially gate-shaped outer wall panel 116. And the opening part 118 is formed in the position which overlaps with the column omission part P seeing from the outdoor side of the unit building 110, when the reinforcement body 112 with an outer wall is assembled | attached to the wife side surfaces 12A and 14A of the building units 12 and 14. FIG. The

  As described above, in the unit building 110, there is almost no difference in height between the floor surface 120 of the indoor entrance of the building units 12 and 14 and the floor surface of the entrance porch on the outdoor side. For this reason, the opening part 118 which connects the indoor and outdoor of the unit building 110 smoothly is formed by assembling the reinforcement body 112 with an outer wall to the end faces 12A and 14A.

  As shown in FIG. 7, the entrance door portion 122 includes an entrance sash 124 and two entrance doors 126, and the upper end portion of the entrance sash 124 is an opening portion of the outer wall panel 116 through the fence 200. 118. Further, the lower end portion of the entrance sash 124 is installed on the floor surface 120. Two entrance doors 126 are slidably supported by the entrance sash 124. The bag 200 includes a main body 130 and a connecting portion 128. The main body 130 projects from the upper end of the opening 118 to the outdoor side along a substantially horizontal direction. On the other hand, the connecting portion 128 is constituted by a structure that extends vertically from the base end portion of the main body portion 130 along a substantially vertical direction. Above the upper end of the opening 118, the upper portion of the connecting portion 128 is inserted between the outer wall panel 116 and the reinforcing beam 46, and is fixed to both the reinforcing beam 46 and the outer wall panel 116. Further, the lower end portion of the connecting portion 128 is placed on the upper end portion of the entrance sash 124. The connecting portion 128 may be a member that also functions as an outer wall frame that connects the reinforcing beam 46 and the outer wall panel 116.

(Function and effect)
Next, functions and effects of the unit building 110 according to the second embodiment will be described.

  The same effect as that of the first embodiment can be obtained by the above configuration. In particular, in this embodiment, as described in the first embodiment, the brackets 52 for fixing the reinforcing beam 46 are fixed at two locations along the direction in which the ceiling beam 26 is formed. Thus, the torsional rigidity of the ceiling beam 26 can be improved. Accordingly, when a front door is provided in the opening 70 of the outer wall panel 44, sufficient torsional rigidity can be maintained even if the cantilevered ridge 200 is provided on the reinforcing beam 46 at the top of the front door. The drooping of the tip of the canopy 200 having a cantilever structure can be suppressed. Further, the degree of freedom of the attached space can be increased, for example, by making the ceiling surface on the building unit 12, 14 side in a state where the canopy entrance 200 is attached.

  In addition, according to the present embodiment, the following effects can also be obtained. That is, in the present embodiment, since the opening 118 that hardly causes a difference in height between the floor surface 120 on the indoor side of the building units 12 and 14 and the floor surface of the entrance porch on the outdoor side is formed, the open feeling of the indoor space is formed. Will improve.

  Moreover, since the floor 120 of the building units 12 and 14 is set lower than the horizontal position of the floor of the normal building unit, the housing design is made by taking advantage of the height difference from the floor of the normal building unit. be able to. For example, even when the entrance is provided on the second floor portion of the house, such as in a housing complex, the floor portion of the entrance portion on the second floor and the living space are formed by forming the entrance portion with the building units 12 and 14. In addition to providing a step on the floor, a spacious entrance can be formed.

[Supplementary explanation of the above embodiment]

(1) In the above-described embodiment, the large openings 34 and 111 that exceed the boundary between the two building units 12 and 14 are formed. For example, if the ceiling beams on the outdoor side and the wife side of three building units are arranged in a straight line and are arranged in parallel so that the temporary columns are adjacent to each other, the openings that cross the boundaries of the three building units A part may be formed. In this case, two temporary columns are provided in the central building unit, and one temporary column is disposed adjacent to the building units located on both sides of the building unit.

(2) In the above-described embodiment, the formation of the reinforcing beam 46 is set to be substantially the same as the formation of the ceiling large beam 26. However, the present invention is not limited to this, and the formation of the reinforcing beam is set smaller than the formation of the ceiling large beam 26. Conversely, it may be set larger.

(3) In the first embodiment described above, no scissors are provided on the upper side of the sweep window portion 72, but a scissors 200 similar to that of the second embodiment may be provided on the upper side of the sweep window portion 72. Moreover, you may provide the member of the cantilever structure used as a sunshade, such as a cantilever floor and an awning, without being restricted to a ridge.

(4) In 2nd Embodiment mentioned above, although the opening part 118 of the reinforcement body 112 with a substantially portal type outer wall was utilized as the entrance door part 122, it is not restricted to this but is connected with an inner garage, an outdoor terrace, etc. It may be used as an opening.

(5) In the above-described embodiment, the connection method between the outer wall-attached reinforcing bodies 40 and 112 and the lower structure is not mentioned. However, as in the normal connection method, if the lower structure is a concrete foundation, the anchor If it connects with a volt | bolt or a post-construction anchor and it is a building unit or a reinforcement body with an outer wall, it should just connect by bolt joining. The number of joints may be two or more, and the strength of the reinforcing body with outer wall can be improved by increasing the number of joints. Further, when the rectangular frame-shaped reinforcing member 40 with the outer wall is used as in the first embodiment, the strength of the reinforcing member 40 with the outer wall is further increased by connecting the floor beam 50 of the reinforcing member 42 to the lower structure. Can be improved.

(6) In the embodiment described above, the grooved steel is used for the support column 48. However, the present invention is not limited to this, and other cross-sectional members such as a square steel pipe may be used. When channel steel is used, the connection between the reinforcing beam 46 and the column 48 can be achieved by, for example, abutting the column 48 with a rectangular flat plate-shaped joint bracket welded to the longitudinal end of the beam 46 to join the column. There is an advantage that it becomes easy.
