Japanese Patent Laid-Open No. 1997-203219 JP 2012-149212 A

  When the column and the outer wall are in the same plane, an earthquake-resistant slit is provided between the side surface of the column and the outer wall to prevent shortening the column. In this case, the seismic slit portion between the side surface of the column and the outer wall needs to have a waterproof structure.

  In view of the above facts, an object of the present invention is to prevent a column from being shortened while easily ensuring waterproof performance.

  The invention of claim 1 has an outer wall joined to a beam or a slab, and a column pillar composed of a plurality of pillars joined to the beam and arranged with a gap from the wall surface of the outer wall, The plurality of columns constituting the row column are composed of a bonding column provided with a filler between the wall surface and bonded to the outer wall, and a non-bonded column not bonded to the outer wall. It is a building structure.

  According to the first aspect of the present invention, it is possible to prevent the column from being shortened by using a non-joined column that is not joined to the wall. In addition, when the pillar and the outer wall are in the same plane, it is superior in waterproof performance (watertight performance) compared to the case where an earthquake-resistant slit is provided between the side of the pillar and the outer wall to prevent shortening the pillar. .

  Moreover, the part which makes an outer wall a load-bearing wall is made into the joining pillar which provided the filler between the wall surfaces of the outer wall, and increased and joined. And the rigidity of an outer wall can be freely adjusted by using together the non-joining pillar which is not joined to the outer wall, and the joining pillar joined to the outer wall.

  The invention according to claim 2 is the building structure according to claim 1, wherein an opening is provided in at least one of a portion between the non-joined columns and a portion facing the non-joined columns in the outer wall. .

  In the second aspect of the present invention, since the portion between the non-joined columns and the portion facing the non-joined column on the outer wall are non-bearing walls, an opening can be provided, for example, for lighting or entrance / exit.

  Invention of Claim 3 is a building structure of Claim 1 or Claim 2 with which the clearance gap between the said outer wall and the said some pillar is set to 100 mm or less.

  In the invention described in claim 3, since the gap between the outer wall and the column is set to 100 mm or less, the amount of increase in the filling material is reduced. Also, the indoor space becomes wider.

(Building structure)
The building structure 10 of this embodiment is demonstrated. In addition, although the building 12 of this embodiment is a reinforced concrete structure, it is not limited to this. In each figure, the reinforcing bars are not shown.

  As shown in FIG. 2, the building 12 to which the building structure 10 of the present embodiment is applied is provided with a column pillar 38 composed of a plurality of pillars 30 arranged in the Y direction on the inner side (indoor side) of the outer wall 20. ing. Each column 30 constituting the column column 38 is disposed with a gap S (see FIG. 1) from the wall surface 22 of the outer wall 20. In addition, A and B after the code | symbol 30 which shows a pillar have shown the non-joining pillar 30A not joined to the outer wall 20, and the joining pillar 30B joined to the outer wall 20 so that it may mention later. Further, when it is not necessary to distinguish between the non-joining column 30A and the joining column 30B, the description will be made by omitting A and B after the reference numeral 30. In addition, the side surface 32 in each column 30 is a surface facing outward in the X direction (out-of-plane direction of the outer wall 20), and the side surface 34 is a surface facing in the Y direction.

  As shown in FIG. 1B, a beam 40 is joined to each column 30. The beam 40 supports the slab 60. Further, the beam 40 is also arranged with a gap S from the wall surface 22 of the outer wall 20 of the building 12 like the column 30. The gap S between the wall surface 22 of the outer wall 20 and the side surfaces 32 of the plurality of columns 30 and the side surfaces 42 of the beams 40 is set to 100 mm or less. In the present embodiment, the gap S is set to 50 mm.

  The beam 40 is bonded to the outer wall 20 by supporting the outer wall 20 by providing a filler 50 such as a mortar between the outer wall 20 and increasing it. Although not shown, a reinforcing bar (for example, a shear reinforcing bar) is arranged across the beam 40 and the outer wall 20. The slab 60 is also joined to the outer wall 20.

  As shown in FIG. 2, of the plurality of columns 30 constituting the column column 38, the column 30 from the left end to the third column 30 and the column 30 at the right end in the drawing are mortar or the like between the column 30 and the outer wall 20. By providing and increasing the filler 52, the outer wall 20 is joined. Although not shown, a reinforcing bar (for example, a shear reinforcing bar) is arranged across the column 30 and the outer wall 20.

  As described above, the pillar 30 that is not joined to the outer wall 20 is referred to as a non-joined pillar 30A, and the pillar 30 that is joined to the outer wall 20 is referred to as a joined pillar 30B. Moreover, arrangement | positioning of the non-joining pillar 30A and the joining pillar 30B in FIG. 2 is an example, Comprising: It is not limited to this.

  And the area | region where the pillar 30 in the outer wall 20 is not joined becomes non-bearing wall 20A (non-bearing wall area), and the area | region where the pillar 30 in outer wall 20 is joined becomes bearing wall 20B (bearing wall area). Moreover, the opening 24 provided with a window, a door, etc. in the part between the non-joining pillars 30A in the outer wall 20 and the part facing the side surface 32A of the non-joining pillar 30A, that is, the non-bearing wall 20A (see FIG. 1). And the opening part 25 is formed.

(Function and effect)
Next, the operation and effect of this embodiment will be described.

  As shown in FIGS. 1 and 2, the non-joint pillar 30A that is not joined to the outer wall 20 is used to prevent the non-joint pillar 30A from being shortened. Moreover, since the outer wall 20 does not have the earthquake-resistant slit 110 (see FIG. 3A) that communicates the inside and outside of the building 12, the waterproof performance is excellent. The earthquake resistant slit 110 will be described later.

  Further, as shown in FIG. 2, the portion where the outer wall 20 is the load-bearing wall 20 </ b> B is a joining column 30 </ b> B in which a filler 52 is provided between the outer wall 20 and the outer wall 20 is joined by repeated striking. And the rigidity of the outer wall 20 can be freely adjusted by using together the non-joining pillar 30A which is not joined to the outer wall 20, and the joining pillar 30B joined to the outer wall 20.

  If it demonstrates from another viewpoint, the area | region used as the non-bearing wall 20A and the area | region used as the bearing wall 20B in the outer wall 20 can be set freely.

  In addition, since the outer wall 20 between the non-joining columns 30A is the non-bearing wall 20A, the opening 24 can be provided as a lighting (window) or an entrance (door).

  In addition, since the clearance S between the outer wall 20 and the column 30 and the beam 40 is set to 100 mm or less (50 mm in this embodiment), the amount of increase by the filler 50 and the filler 52 is reduced.

  Here, the building structure 100 of the comparative example shown in FIG. 3 is demonstrated. In addition, the same code | symbol is attached | subjected to the member same as the building structure 10 of this embodiment, and the overlapping description is abbreviate | omitted.

  As shown in FIG. 3, in the building 112 to which the building structure 100 of the comparative example is applied, the column 30 and the beam 40 and the outer wall 20 are in the same composition plane, and the side surface 34 of the column 30 and the end surface 26 of the outer wall 20. A seismic slit 110 is provided between the column 30 and the column 30 to prevent shortening.

  In the case of such a building structure 100, the seismic slit 110 communicates between the side surface 34 of the pillar 30 and the end surface 26 of the outer wall 20, that is, the inside and outside of the building 112. It is necessary to fill and seal to have a waterproof structure. However, such a waterproof structure using the sealing agent 120 has a limit in waterproof performance (watertight performance).

  On the other hand, in the building structure 10 of the present embodiment shown in FIGS. 1 and 2, the non-joint column 30 </ b> A is provided with a gap S between the wall surface 22 of the outer wall 20 to prevent shortening. Therefore, since there is no site | part which connects the inside and outside of a building like the earthquake-resistant slit 110 (FIG. 3 (A)), a water leak is prevented. That is, compared with the building structure 100 of the comparative example, the building structure 10 of this embodiment is superior in waterproof performance (watertight performance).

  As described above, the building structure 10 of the present embodiment prevents the column 30 (non-joined column 30A) from being shortened while easily ensuring waterproof performance.

  The present invention is not limited to the above embodiment.

  For example, in the above embodiment, as shown in FIG. 2, the opening 24 is provided in a portion between the non-joining columns 30 </ b> A in the outer wall 20, and the opening 25 is provided in a portion of the outer wall 20 facing the side surface 32 </ b> A of the non-joining columns 30 </ b> A. However, the present invention is not limited to this. Only one of the opening 24 and the opening 25 may be formed. Alternatively, the openings 24 and 25 may not be formed in the non-bearing wall 20A.

  Further, for example, in the above embodiment, as shown in FIG. 1B, the beam 40 is added and joined to the outer wall 20 to support the outer wall 20, but the present invention is not limited to this. The beam 40 may not be joined to the outer wall 20, and only the slab 60 may be joined to the outer wall 20.

  Furthermore, it cannot be overemphasized that it can implement with a various aspect in the range which does not deviate from the summary of this invention.
