この発明は、複数個の建物ユニットの内階下建物ユニットと階上建物ユニットとで吹き
抜け部が形成され、前記階下建物ユニットの天井部梁と前記階上建物ユニットの床部梁と
が上下方向に対向して配置され、固定された建物の梁構造に関するものである。 According to the present invention, an atrium is formed by an inner floor building unit and an upper building unit of a plurality of building units, and a ceiling beam of the lower building unit and a floor beam of the upper building unit are vertically arranged. It is related to the beam structure of the building which is arranged oppositely and fixed.

従来、この種の技術は、図１に示す複数個の建物のユニットを重ねて構成する建物で、

この梁構造は、階下建物ユニットの外枠を形成する天井部梁と階上建物ユニットの外枠を
形成する床部梁とが上下方向に配置され、固定されている。 Conventionally, this type of technology is a building constructed by stacking a plurality of building units shown in FIG.
For example, a beam structure of a building having an atrium (Patent Document 1) is known. According to this,
In this beam structure, the ceiling beam that forms the outer frame of the lower building unit and the floor beam that forms the outer frame of the upper building unit are arranged vertically and fixed.

この吹き抜け部の梁は、隣接する建物ユニットが位置するところは、横荷重に対して十
分な強度を発揮するが、外壁に直接沿うところは、長いスパンにわたって横荷重を支持す
るものがなく何らかの対策を講じなければならなかった。 The beam in the atrium shows sufficient strength against lateral load when the adjacent building unit is located, but there is nothing to support the lateral load over a long span where it is directly along the outer wall. Had to take.

そこで、図示を省略するが、外壁に沿う梁と内壁に沿う梁との間の中間部に梁を掛け渡

特開平８−１３７３４号公報 Therefore, although not shown in the figure, the beam is routed in the middle between the beam along the outer wall and the beam along the inner wall. .
As a countermeasure against this, the beam itself was reinforced as shown in FIG. In other words, the U-shaped cross-section reinforcing beam members 5 that are just inside the U-shaped cross-section beam material 1 that constitutes the outer frame of the building unit are assembled so as to be embraced with their open sides facing each other, and the upper and lower surfaces are joined together. Arc welding 7 was intermittently performed. A plurality of weight reduction ports 3 are opened in the longitudinal direction.

分な軽量化には至らなかった。 However, with such a technique, welding in a bead shape such as arc welding, a large amount of heat is applied unlike resistance welding, which causes warping, bending, or deformation, resulting in dimensional errors. As a result, there were problems in assembly. Further, since the reinforcing beam member 5 is approximately the same size as the beam member 1, a plurality of weight reducing ports 3 are provided for reducing the weight, but the weight has not been reduced sufficiently.

そこで、この発明は、上記問題に鑑みて建物の重量増加を極力抑え、十分な強度の吹き
抜け空間を持った建物とする建物の梁構造を提供することを目的としている。 In view of the above problems, an object of the present invention is to provide a building beam structure that suppresses an increase in the weight of a building as much as possible and has a sufficiently strong atrium space.
