鉄骨建築は、図1に示すように、通常は角形鋼管・丸形鋼管・H形鋼による柱1とH形鋼による梁2からなっており、該柱と梁の接合部は仕口であり、図2に示すように、角形鋼管を使った柱1の場合、仕口部3はダイアフラム5と柱短管6の部品から構成され溶接7により製作され、該仕口部と柱1と梁2が溶接7で接合されている。   As shown in Fig. 1, a steel building is usually composed of a square steel pipe, a round steel pipe, a pillar 1 made of H-shaped steel and a beam 2 made of H-shaped steel, and the joint between the pillar and the beam is a joint. As shown in FIG. 2, in the case of a column 1 using a square steel pipe, the joint portion 3 is composed of parts of a diaphragm 5 and a short column tube 6 and is manufactured by welding 7, and the joint portion, the column 1 and the beam are formed. 2 are joined by welding 7.

鉄骨建築構造を支えているのが、図1で示す基礎4である。この基礎4は、独立基礎、一つの基礎で2本以上の柱を支える複合基礎、フーチングを連続して形成する布基礎がある。これらの基礎を作ってから柱1を基礎に接続して、建築物と基礎とが一体になるのである。   The foundation 4 shown in FIG. 1 supports the steel building structure. The foundation 4 includes an independent foundation, a composite foundation that supports two or more pillars with one foundation, and a fabric foundation that continuously forms footings. After these foundations are made, the pillar 1 is connected to the foundation, and the building and the foundation are united.

図4に、従来の独立基礎の上に構築した鉄骨建築模式図を示す。建築は、大略柱1,梁2、接合部即ち仕口部3からなっており、柱1を支持する基礎柱又は杭8を設置する地盤9を所定深さまで掘削して所定形状の穴を形成させ、穴の所に所定形状の型枠を製作して、コンクリート10を打設して、1週間ほどの養生期間を得て、固まらせる。また、水平材の基礎梁11で基礎間を連結し、建物全体の剛性を上げて不同沈下を押さえているのである。   FIG. 4 shows a schematic view of a steel building constructed on a conventional independent foundation. The building is generally composed of pillars 1, beams 2, and joints or joints 3. The foundation 9 that supports the pillars 1 or the ground 9 on which the piles 8 are installed is excavated to a prescribed depth to form holes of a prescribed shape. Then, a mold having a predetermined shape is produced at the hole, and the concrete 10 is placed, and a curing period of about one week is obtained and solidified. Moreover, the foundation beams 11 of horizontal members are used to connect the foundations to increase the rigidity of the entire building, thereby suppressing uneven settlement.

特願平9−348841(特開平11−181790号公報:引用文献1)の例を示す。図5に、従来型の基礎を改良した杭柱一体型工法の模式図を示す。該工法では、従来のような基礎は使わず、先端につけたスクリュー19で地盤9に鋼管杭18をねじ込んで、該鋼管杭18の地表部分で適当な寸法に上部を切断して一定の高さを確保して杭フランジ16を溶接して、該杭フランジ16と柱ベースプレート12とをスペーサ17を挟んでボルト15とナット14で固定する。 An example of Japanese Patent Application No. 9-348841 (Japanese Patent Laid-Open No. 11-181790: Cited Reference 1) is shown. In FIG. 5, the schematic diagram of the pile pillar integrated construction method which improved the foundation of the conventional type is shown. In this construction method, a conventional foundation is not used, and a steel pipe pile 18 is screwed into the ground 9 with a screw 19 attached to the tip, and the upper portion is cut to an appropriate dimension at the surface portion of the steel pipe pile 18 to a certain height. The pile flange 16 is welded, and the pile flange 16 and the column base plate 12 are fixed with bolts 15 and nuts 14 with a spacer 17 interposed therebetween.

And by adjusting the horizontal position adjustment 42, the joint groove gap G between the column 1 and the solid steel material 17 is adjusted, and after adjusting the height of the column 1, the column 1, the backing metal 20, and the solid steel material 17 are adjusted. Or the temporary fixing piece 21 is used to fix the column 1 and the solid steel material 17 by temporary welding, and then the joint weld 7 is applied. In addition, the two solid steel materials by rolling, forging, or casting that are aligned in the horizontal direction can be welded to each other at the upper, lower, and side surfaces depending on the strength requirements of the joint. When performing groove processing, it is performed as shown in FIG. 8 as an example, and it is also possible at a construction site, but it is better to carry out in advance at a steel factory. Furthermore, the installation position of the solid steel material 17 is determined by connecting the solid steel material 17 to the steel pipe pile 18 and the column 1 according to the upper cutting position of the steel pipe pile 18, and then in the ground, between the ground and the ground, on the ground surface, or on the ground. Either is possible. The shape of the steel material 17 is not limited to a hexahedron, but may be an octahedron, a sphere, an ellipsoid, or a cylinder. FIG. 9 shows an application of FIG. 6 in which a solid steel material 17 is provided wider than in the case of FIG. 6 and one column 1 is attached to the upper part and one steel pipe pile 18 is attached to the lower part. In this case, even if the core of the column 1 and the core of the steel pipe pile 18 are displaced, the upper column 1 and the lower steel pipe pile 18 are easily attached as a continuous body. FIG. 10 is also an application of FIG. 6, in which a solid steel material 17 is provided wider than in the case of FIG. 6, and one column 1 is attached to the upper part and two steel pipe piles 18 are attached to the lower part.

In this case, since the solid steel material 17A is welded and joined to the steel pipe pile 18 first, and then the solid steel material 17 is welded and joined 7F, there is an advantage that welding work is easy in a downward posture. Moreover, if the stopper of the solid steel material 17 is attached to the steel pipe pile 18 of the lower side of the solid steel material 17, it will become positioning of the solid steel material 17 and reinforcement of the welding part 17S, and with respect to the vertical load by the steel column 1 Increase yield strength.
