Are provided with mounting holes for mounting to the floor beam 12a with bolts or the like.

  Further, as shown in FIG. 6, the protruding portion 32b is formed in a plate shape having an inverted T-shaped cross section by a steel plate or the like, and is fixed to the mounting portion 32a by welding and then is reinforced by reinforcing plates 32e and 32e. While being reinforced, the web 32c and the flange 32d are provided with fixing holes for fixing the end beam 21.

  Therefore, the web 32c of the protruding portion 32b of the juxtaposed portion mounting bracket 32 is fixed to the web of both the beam beams 21 and 21 by bolts or the like, and the flange 32d of the protruding portion 32b is below the both beam beams 21 and 21. It is fixed to the flange with bolts.

  The length of the projecting portion 32b in the projecting direction is formed so as to be at least approximately half the total length of the adjacent beam 21 so that the reinforcement effect on the beam 21 is increased. In addition, it is preferable from the surface of the reinforcement effect that the length of the protruding portion 32b in the protruding direction is substantially the same as the length of the end beam 21.

  In addition, the beam back, which is the height of the web 32c of the protruding portion 32b, is formed so as not to protrude above the finished surface of the floor panel 26.

  And the attachment metal fitting 31 arrange | positioned at a protruding corner part is formed with a steel plate, and is supporting the end beam 21 of the protruding corner part of the balcony 2, as shown to FIG.

  Furthermore, the receiving metal fitting 33 arranged in the vicinity of the center of the second floor of the building unit 12 supports the vicinity of the center of the beam 22 closer to the unit building 1 of the balcony 2.

  The bracket 33 is formed by bending a steel plate into a substantially L shape, and one surface is attached to the floor beam 12a of the second floor building unit 12 with a bolt or the like, and the other surface is the floor panel 26. The girder beam 22 is fixed to the girder beam 22 with a bolt or the like while the girder beam 22 is supported.

Next, the operation and effect of the balcony of Reference Example 1 described above will be described.

(1) As described above, the balconies 2 and 2 include the floor panel 26, the mounting bracket 31 for attaching the floor panel 26, and the side-by-side mounting bracket 32, and the floor panel 26 projects from the building unit 12. To form.

  The juxtaposed portion mounting bracket 32, which is a mounting bracket, includes a mounting portion 32a that is fixed to a floor beam 12a as a building structure, and a protruding portion 32b that protrudes from the mounting portion 32a along the direction in which the floor panel 26 extends. And have.

  For this reason, it is possible to reinforce the protruding portion 32b by the end beam 21 and lower the plate back of the protruding portion 32b while reinforcing the end beam 21 by the protruding portion 32b of the juxtaposed portion mounting bracket 32 to lower the beam back. The thickness of the entire floor panel 26 can be reduced.

And in the balcony 2 of the reference example 1 , the floor panel 26 is juxtaposed along the building unit 12, and the juxtaposed portion mounting bracket 32, which is a mounting bracket, is connected to the adjacent beams 21, 21 of the floor panels 26, 26. The projecting part 32b is sandwiched between the adjacent beams 21 and 21 and is joined.

  Therefore, even when there is no other building unit below the balcony 2, the floor panel 26 can be attached to the building structure by the juxtaposed portion mounting bracket 32.

  In addition, the projection beam 32 is reinforced by the projection 32b of the juxtaposed part mounting bracket 32 to lower the beam back of the beam 21, and the projection 32b is reinforced by the projection beam 21 to thereby reduce the plate back of the projection 32b. By reducing the thickness, the entire thickness of the floor panel 26 can be reduced.

  That is, in the juxtaposed portion, the three members of the one cross beam 21, the juxtaposed portion mounting bracket 32, and the other cross beam 21 reinforce each other, thereby suppressing the height of each member.

  (2) And the protrusion part 32b of the juxtaposed part mounting bracket 32 is formed to have at least approximately half the length of the end beam 21 as a beam member, so that the end beam is effectively prevented by the protrusion part 32b. 21 can be reinforced.

  In other words, by reinforcing the predetermined range in the vicinity of the base of the beam beam 21 where the load is applied to the balcony 2 with the juxtaposed portion mounting bracket 32, the beam back of the beam beam 21 can be kept low. .

  (3) Of the beam members of the floor panel 26, the beam back of the end beam 21 as one beam member joined to the projecting portion 32 b is formed lower than the beam back of the opposite other beam 21. Thus, while the thickness of the entire floor panel 26 is reduced, the rigidity of the entire floor panel 26 can be maintained by the end beam 21 as the other beam material.

  That is, in the juxtaposed part where the balconies 2 are joined together, by preventing the one beam 21 from projecting above the finished surface, the number of parts can be reduced, the workability is improved, and obstacles during passage Effects such as disappearance of objects and improvement in appearance design are achieved.

  In addition, even if the other end beam 21 protrudes above the finished surface at the projecting corner, there is little problem just by projecting into the wall of the balcony 2, so the beam back is raised and the rigidity of the entire floor panel 26 is increased. Is raised.

  (4) Further, the mounting bracket 31 at the protruding corner includes a mounting portion 31a that is attached to the column 12b as a building structure, and a protruding portion that is attached to the beam 21 and the girder beam 22 as the beam material of the floor panel 26. 31b, and the back of the protruding portion 31b is formed so as not to protrude above the finished surface of the floor panel 26, thereby eliminating the need to provide a cover for protecting the protruding portion 31b.

That is, before the reference example 1 , since the protruding portion 31b of the mounting bracket 31 protruded above the finished surface of the floor panel 26, it was necessary to provide a cover for covering this. Therefore, by suppressing the plate height (height) of the protruding portion 31b, the cover is unnecessary while securing the necessary strength, although the mounting strength is slightly inferior.

  (5) In addition, the floor beam 26a is supported by the floor beam 12a as the structure of the building by supporting the girder beam 22 as the beam material along the building of the floor panel 26 from below. Even when the thickness is reduced, it is possible to suppress bending and vibration and obtain a stable walking feeling.

  That is, when the floor panel 26 is made thin, it is predicted that there will be problems with bending and vibration due to load, so that the natural frequency is changed by supporting the middle part of the beam 22 in order to prevent this. It improves the feeling of walking.

(6) The unit building 1 includes any one of the balconies 2 described above, so that the floor panel 26 of the balcony 2 has a predetermined rigidity, but the thickness of the entire floor panel 26 is reduced. It becomes.

  In addition, if the floor panel 26 of the balcony 2 can be made thin and the floor level can be lowered in this way, parts can be shared with a normal balcony that does not project in a cantilevered manner, and the cantilevered shape can also be achieved. It is also easy to continuously arrange the balcony 2 and the normal balcony.

  Further, in the past, joists were installed on the small beams 23,..., But by placing face materials directly on the joists 23,. It is possible to reduce and improve workability.

At this time, since the extending portion 34ab has an L-shaped cross section, the mounting plate 36b can be temporarily placed on the extending portion 34ab, and positioning can be performed easily.

  Then, the extending part 34ab and the mounting plate 36b are fixed via bolts (not shown), and one end beam 21 is fixed to the building unit 12.

  Thereafter, the other beam 21 arranged side by side with the reinforcing plate 34bb is fixed to the other beam 21 already fixed to the building unit 12. At this time, since the extended portion 34ab is fixed at a position offset to the center side of the building unit 12, the floor panel joint surface S1 of the side beams 21 and 21 arranged side by side and the building of the adjacent building units 12 and 12 are arranged. The position with the unit joint surface S2 can be matched (see FIG. 9B).

  Further, by sandwiching the reinforcing plate 34bb between the end beams 21, 21, even if the height of the beam back is reduced, the floor panel can be prevented from being bent, and the thickness of the entire floor panel can be reduced.
