This invention relates to a method of constructing a building frame.

。Conventionally, when constructing a building frame with such columns, for example, a steel pipe is erected at the construction site, a beam is connected to the steel pipe at a predetermined height, and then concrete is filled inside the steel pipe. However, a method has also been adopted in which a new steel pipe is joined to the upper end of the steel pipe and the same operation is repeated.

た。[Problem to be solved by the invention] By the way, if the framework is assembled using the above construction method,
The steel pipes that make up the columns and the concrete inside are attached to each other. Therefore, the steel pipe and concrete are displaced together by the axial compressive load applied to the column, and the amount of axial strain in both becomes equal. By the way, if the Mises yield condition is applied to the yielding of a steel pipe, the stress in the axial direction will almost reach the yield, and the confining effect (circumferential stress) that tightens the concrete as it swells is not sufficient. The problem was that people could not expect much from the future.

る。"Function" If a building frame is constructed using the method of the present invention, the steel pipe and concrete will be in a non-adhesive state, so that when the column is displaced in the axial direction, a shift will occur between the steel pipe and the concrete. In other words, steel pipes try to receive compressive loads directly from beams, but
At this time, most of the axial strain that should occur in the entire steel pipe is absorbed by the axial deformation of the elongated hole, and the amount of strain and stress in other parts become zero. On the other hand, the concrete receives a compressive load from the concrete via the bearing member, and is displaced by supporting this compressive load by itself, but the steel pipes try to resist the radially outward displacement at this time. do. That is, the steel pipes clamp the concrete radially inward.

次いで、上記のようにして製造した柱用組立鋼管lを使

立鋼管lの内部に鉄筋(図示路)を配筋しておく。First, a plurality of prefabricated steel pipes l for columns are prepared, lifted one by one by a crane, etc., and erected on the foundation of the construction site as shown in FIG. At this time, make sure that the elongated hole installation part 4 at one end of the assembled steel pipe l for the column is on the lower side. After that, *Process (1) As shown in FIG. 7, the katai 11 is passed between the joint parts 3 of the assembled steel pipes 1 for pillars erected adjacently, and the ends of the katoshi 11 and the The ends of the main steel frame member 8 are joined by welding, bolts, or the like. In addition, at this time, reinforcing bars (as shown in the diagram) are arranged inside the assembled steel pipes 1 for columns as necessary.

全体に生じるべき歪は長穴9が軸方向に変形することに
よりほとんど吸収されて長穴配設部4以外の他の部分で
は歪量がゼロとなる。すなわち、鋼管2はその半径方向
外方にはほとんど変位しない。When constructing a building frame in this way, the steel pipe 2 and the concrete 12 are not attached, so when the column is displaced in the axial direction due to an axial compressive load, there is a gap between the steel pipe 2 and the concrete ■2. Misalignment occurs. In other words, steel pipe 2
receives a compressive load directly from the pipe 11, but at this time the steel pipe 2
Most of the strain that should occur in the entire structure is absorbed by the axial deformation of the elongated hole 9, and the amount of strain in other parts other than the elongated hole disposed portion 4 becomes zero. That is, the steel pipe 2 is hardly displaced radially outward.
一方、コンクリート12は粱IIから支圧部材5を介し

て変位する。このときコンクリート12の半径方向外方
への変位を前記鋼管2が邪魔する。On the other hand, the concrete 12 receives a compressive load from the casing II via the bearing member 5, and substantially supports this compressive load by itself and is displaced. At this time, the steel pipe 2 obstructs the radially outward displacement of the concrete 12.

You may also use one that you have three or more of. Alternatively, the joints 11 may be joined after two or more assembled steel pipes 1 for columns are connected at a construction site. Furthermore, when arranging reinforcing bars in the assembled steel pipe for columns 1, prestress may be introduced into the reinforcing bars.
