Description

本発明は、屋根構造に関する。 The present invention relates to a roof structure.

陸屋根及び傾斜屋根を有する建物において、陸屋根の屋根面と傾斜屋根の屋根面とを、パラペットで仕切ることなく連続させ、陸屋根に溜まった雨水を傾斜屋根の方に流せるようにしたものが従来知られている。
また、こうした建物においては、傾斜屋根の屋根面にも、陸屋根の屋根面と同様の防水シートを貼り付けることが行われている(例えば特許文献1参照)。
In a building having a flat roof and a sloping roof, it has been conventionally known that the roof surface of the flat roof and the roof surface of the sloping roof are continuous without being separated by a parapet so that rainwater collected on the flat roof can flow toward the sloping roof. ing.
Further, in such a building, a waterproof sheet similar to the roof surface of a flat roof is attached to the roof surface of a sloping roof (see, for example, Patent Document 1).

特開2010−001710号公報JP-A-2010-001710

しかしながら、従来の陸屋根の屋根面と傾斜屋根の屋根面とを連続させた建物においては、傾斜屋根を流れ落ちた雨水が、傾斜屋根の下方にある外壁にかかったり、傾斜屋根と外壁との目地に入り込んだりしてしまうことがあった。
こうした雨水は、外壁材や内部の躯体を劣化させてしまう原因となる。
However, in a building in which the roof surface of a conventional flat roof and the roof surface of a sloping roof are continuous, rainwater that has flowed down the sloping roof splashes on the outer wall below the sloping roof, or at the joint between the sloping roof and the outer wall. I sometimes got in.
Such rainwater causes deterioration of the outer wall material and the internal skeleton.

本発明は上記事情に鑑みてなされたものであり、陸屋根の屋根面と傾斜屋根の屋根面とを連続させた建物において、傾斜屋根を流れ落ちた雨水が、傾斜屋根の下方にある外壁にかかったり、傾斜屋根と外壁との目地に入り込んだりすることを防ぐことを目的とする。 The present invention has been made in view of the above circumstances, and in a building in which the roof surface of a flat roof and the roof surface of a sloping roof are continuous, rainwater flowing down the sloping roof may be applied to the outer wall below the sloping roof. The purpose is to prevent it from entering the joint between the sloping roof and the outer wall.

FIG. 8 is a side view showing the state of the skeleton 1 in the middle of construction, and FIG. 9 is a perspective view showing the state of the roof structure 100a in the middle of construction.

(4−1.柱の溶接)
本実施形態に係る建物100の斜め柱14は、複数の鋼材(角型鋼管)を完全溶込み溶接(突合せ溶接)することで施工する。
この斜め柱14を施工するには、まず、図8(a)に示すように、斜め柱14の相対的に下部となる下部鋼材14aの上端部の裏側側面(角型鋼管の場合には内側表面)に裏当て部材14bを取り付ける。
裏当て部材14bは、溶接してもよいし、固定具で固定してもよい。
裏当て部材14bは、下部鋼材14aの上端から所定の突出長さα突出するように取り付ける。
(4-1. Welding of columns)
The diagonal column 14 of the building 100 according to the present embodiment is constructed by completely penetration welding (butt welding) a plurality of steel materials (square steel pipes).
In order to construct the diagonal column 14, first, as shown in FIG. 8A, the back side surface (inside in the case of a square steel pipe) of the upper end portion of the lower steel material 14a which is a relatively lower part of the diagonal column 14. The backing member 14b is attached to the surface).
The backing member 14b may be welded or fixed with a fixture.
The backing member 14b is attached so as to project from the upper end of the lower steel member 14a by a predetermined protrusion length α.

また、裏当て部材14bの取り付けに前後して、又は並行して、斜め柱14の相対的に上部となる上部鋼材14cの下端部の内側表面に下がり止め部材14dを取り付ける。
下がり止め部材14dは、溶接してもよいし、固定具で固定してもよい。
下がり止め部材14dは、上部鋼材14cの下端から所定の突出長さαよりも短い距離β奥まった位置に取り付ける。
Further, before, after, or in parallel with the attachment of the backing member 14b, the lowering prevention member 14d is attached to the inner surface of the lower end portion of the upper steel material 14c which is relatively upper of the diagonal column 14.
The lowering prevention member 14d may be welded or fixed with a fixture.
The lowering prevention member 14d is attached at a position behind the lower end of the upper steel material 14c by a distance β shorter than a predetermined protrusion length α.

次に、下部鋼材14aを立設する。
そして、図8(b)に示すように、上部鋼材14cを下部鋼材14aの上に配置する。
このとき、裏当て部材14bが下がり止め部材14dに当接するとともに、上部鋼管の裏側側面(角型鋼管の場合には内側表面)に当接する。
また、上述したように、上部鋼材14cの下端から下がり止め部材14dまでの距離βが、裏当て部材14bの突出長さαよりも短いため、上部鋼材14cと下部鋼材14aとの間には、幅α−βの隙間ができる。
Next, the lower steel material 14a is erected.
Then, as shown in FIG. 8B, the upper steel material 14c is arranged on the lower steel material 14a.
At this time, the backing member 14b abuts on the lowering prevention member 14d and also abuts on the back side surface (in the case of a square steel pipe, the inner surface) of the upper steel pipe.
Further, as described above, since the distance β from the lower end of the upper steel material 14c to the lowering prevention member 14d is shorter than the protruding length α of the backing member 14b, there is a gap between the upper steel material 14c and the lower steel material 14a. There is a gap with a width of α-β.

次に、この隙間を用いて上部鋼材14cと下部鋼材14aとを完全溶け込み溶接によって接合する。
こうすることで、図8(c)に示すように、隣り合う二つの鋼材とその溶接部とに跨って当接する裏当て部材14bと、上部鋼材14cと裏当て部材14bとに当接する下がり止め部材14dと、有する斜め柱14が施工される。
なお、この柱の施工方法は、短柱11,長柱の継ぎ足しにも用いることができる。
Next, the upper steel material 14c and the lower steel material 14a are joined by complete penetration welding using this gap.
By doing so, as shown in FIG. 8C, the backing member 14b that comes into contact with the two adjacent steel materials and their welded portions, and the lowering stopper that comes into contact with the upper steel material 14c and the backing member 14b. The member 14d and the diagonal pillar 14 having the member 14d are constructed.
It should be noted that this pillar construction method can also be used for adding short pillars 11 and long pillars.

(4−2.屋根構造の施工)
本実施形態に係る屋根構造100aを施工するには、まず、図9(a)に示すように、傾斜屋根部120の第二屋根面121の下端部と、第一外壁部130の外壁面3aの上端部とに跨るように、捨て貼りシート25を貼り付ける。
