Description
【考案の詳細な説明】 この考案はラチス梁に関するものである。[Detailed explanation of the idea] This idea is related to lattice beams.
従来より、柱、梁を主体とした軸組工法により1階と2
階の壁パネルをラチス梁に建込む場合には、第1図のよ
うに、軽量鋼を山形に形成したつば付きの外壁取付用の
土台金具1を、ラチス梁2の上面にボルト止めするとと
もにそのラチス梁2の下面に畦溝形鋼からなる冠3を溝
部に下向きに固定し、1階の壁パネル4の上面を冠3に
、土台金具1の上面に2階の壁パネル5をそれぞれ嵌着
するようにしていた。Traditionally, the first and second floors have been built using a framework construction method that mainly uses columns and beams.
When building floor wall panels on lattice beams, as shown in Figure 1, a base metal fitting 1 for mounting on an exterior wall with a chevron-shaped brim made of lightweight steel is bolted to the top surface of the lattice beam 2. A crown 3 made of ridge-grooved steel is fixed downwardly in the groove on the lower surface of the lattice beam 2, and the upper surface of the wall panel 4 on the first floor is the crown 3, and the upper surface of the base metal fitting 1 is the wall panel 5 on the second floor. I was trying to get it to fit.
そのため、これらの施工に手間を要するうえラチス梁2
の重量が土台金具1と冠3の分だけ大きくなって取扱い
に不便でありかつ材料コストが高くなるという問題があ
った。Therefore, the construction of these beams is time-consuming, and the lattice beams 2
The weight of the base metal fitting 1 and the crown 3 is increased by the weight of the base metal fitting 1 and the crown 3, which is inconvenient to handle and increases the material cost.
したがって、この考案の目的は、他の建材との結合が容
易でかつ軽量なラチス梁を提供することである。Therefore, the purpose of this invention is to provide a lightweight lattice beam that can be easily combined with other building materials.
この考案の一実施例を第2図に示す。An embodiment of this invention is shown in FIG.
すなわち、このラチス梁は、2本の軽Z形鋼6を対向接
合して溝部7とその溝部背面に凸出8を形成した上弦材
9をその溝部7を下向きにするとともに、溝部10を下
向きにした畦溝形鋼からなる下弦材11の上方に一定間
隔をおいて対向配置し、これらの上弦材9の溝部7の内
側と下弦材11の溝部背面とを波形に折曲した長尺の鉄
筋からなるウェブ材12により連結して溶接固定したも
のである。That is, this lattice beam is made by joining two light Z-beams 6 facing each other to form a groove 7 and a protrusion 8 on the back surface of the upper chord member 9, with the groove 7 facing downward and the groove 10 facing downward. A long piece of elongated material is arranged above the lower chord members 11 made of ridge-and-grooved steel and facing each other at a constant interval, and the inside of the groove part 7 of the upper chord member 9 and the back surface of the groove part of the lower chord member 11 are bent into a wave shape. They are connected and fixed by welding using a web material 12 made of reinforcing steel.
このように構成した結果、第2図で示すようにその下弦
材11の溝部10を1階の壁パネル13の上端縁に冠着
するとともに上弦材9の凸条8に2階の壁パネル14の
下端に設けた結合用溝部15を嵌合することにより、ラ
チス梁の架設ならびに1゜2階の壁パネル13.14の
結合を簡単に行うことができる。As a result of this configuration, as shown in FIG. By fitting the connecting groove 15 provided at the lower end of the lattice beam, the lattice beam can be easily constructed and the wall panels 13 and 14 of the 1.degree. second floor can be connected easily.
また、このラチス梁は、壁パネル13.14との結合部
となる凸条8と溝部10がラチス梁本体に一体的に形成
されているため強度が高くしかも軽量であるという利点
がある。Further, this lattice beam has the advantage of being high in strength and lightweight since the protrusions 8 and the grooves 10, which are the connecting portions to the wall panels 13 and 14, are integrally formed in the lattice beam body.
さらに、下弦材11は溝形のものであるから、市販の溝
形鋼をそのまま用いることができ、また上弦材9は凸条
8を有する溝形のものであるから、この実施例のように
2本のZ形鋼を用いる等して簡単に得ることができる。Furthermore, since the lower chord member 11 is in the shape of a groove, commercially available channel steel can be used as is, and the upper chord member 9 is in the groove shape with the ridges 8, so as in this embodiment, It can be easily obtained by using two Z-shaped steels.
そのため、上弦材や下弦材11を特別にロール成形等で
製造する必要がなく、製造が簡単である。Therefore, there is no need to specially manufacture the upper chord material and the lower chord material 11 by roll forming or the like, and manufacturing is simple.
以上のように、この考案のラチス梁は、上面に長手方向
に沿う凸条を一体形成した下向き溝形の上弦材と下向き
溝形の下弦材とを一定間隔をおいて対向配置し、波形に
折曲した長尺のウェブ材を溶接固定して前記上弦材と下
弦材とを連結したものであるため、他の建材との結合が
容易でかつ軽量であり、材量コストならびに施工コスト
を低減できるという効果がある。As described above, the lattice beam of this invention has a downwardly grooved top chord and a downwardly grooved bottom chord, which are integrally formed with longitudinal protrusions on the top surface, and are arranged facing each other at a constant interval. Since the upper chord member and the lower chord member are connected by welding and fixing a long bent web material, it is easy to connect with other building materials and is lightweight, reducing material cost and construction cost. There is an effect that it can be done.
