The above (1) has the following problems.
Highly-advanced work is required to bridge the beam between the upper ends of the columns and to surround the reinforcing bars at the ends of the columns with formwork, etc. so that the reinforcing bars at the upper ends of the columns and the beams at the ends of the beams have a predetermined positional relationship. There is a drawback that requires skill, and in the case of the above (2), the work of enclosing the periphery of the reinforcing bar of the connection with the formwork becomes easy, but the precast reinforced concrete column-beam body becomes very heavy, and the transportation and There are disadvantages that the lifting is troublesome and requires heavy equipment. In the case of (3) and (4), the portions of the cross steel frames 2A and 3A formed of the steel frames 2a and 3a of the connection members 2 and 3 are buried in the concrete portion of the connection portion.
Although the vertical force acting on the connection members 2 and 3 can be transmitted to the reinforced concrete columns 1 well, the upper and lower columns 1 of the connection members 2 and 3 are made of reinforced concrete. Cannot be transmitted to the column 1 properly, and an unreasonable force acts on the joint between the joint members 2 and 3 and the reinforced concrete column 1, and this portion may be damaged. It is an object of the present invention to provide a building body in which a pillar and a connection member which do not have the drawbacks of the above (1) to (4) are combined and a construction method thereof. In other words, the axial force acting on the column can be reliably transmitted to the concrete in the column steel, the moment acting on the joint can be accurately distributed to the column steel, and the joint structure and the column can be unitized. Another object of the present invention is to provide a building frame and a method of constructing the building, which can be easily transported and lifted, and do not require a high level of construction work on site.

[0007] The long column steel frame of the column and the short column steel frame of the connection structure are joined as follows. (A) A connection member is placed on each pillar built at a pillar formation position of a lower vehicle body, and a concave portion or a convex portion at an upper end of the pillar and a convex portion or a concave portion at a lower end of the connection member are aligned. When the joints are fitted to each other and no axial force is applied to the short and long column steel frames, the end face of the concrete part of the connection structure and the column are introduced by the introduction of tensile force to the connecting rebar or the weight of the upper frame. With the end faces of the concrete portions being pressed against each other, the upper end of the long column steel frame of the column and the lower end of the short column steel frame of the connection structure are joined by welding. (B) A column is erected on the joint structure of the lower body, and the concave or convex portion at the upper end of the joint and the convex or concave portion at the lower end of the column are fitted to each other to form a short column steel frame and With no axial force acting on the long pillar steel frame, the end face of the concrete part of the joint structure and the end face of the concrete part of the pillar body are connected to each other by introducing the pulling force to the driving weight of the upper frame or the connecting rebar. In the pressed state, the lower end of the short column steel frame of the connection structure and the upper end of the long column steel frame of the column body are joined by welding. In order to prevent an axial compressive force from acting on the short column steel frame and the long column steel frame at the time of pressing the end face of the joint member and the concrete portion of the column, for example, the concrete portion of the joint member and the column The connection structure and the column are formed so that the end surfaces around the upper and lower ends of the upper and lower ends slightly protrude from the upper and lower end surfaces of the short and long column steel frames. And when the end faces of the concrete part are pressed against each other,
A gap suitable for welding is formed between the end face of the short column steel frame and the end face of the long column steel frame. This way,

The method of joining the column steel structure 21 of the column body 20 and the column steel structure 11 of the connection structure 10 is performed as follows. The lower part of the connection structure 10 and the upper part of the column 20 are firmly connected by a connecting steel bar 23 to which a tensile force is introduced, and as shown in FIG. Convex part 1
4b and the peripheral surface of the concave portion 22a in the upper part of the concrete portion of the column 20 are pressed against each other, and the inclined lower end surface 11b of the short steel column 11 and the long steel column 31
A gap g suitable for welding is formed between the upper end surface 21a and the inclined upper end surface 21a. In this state, the frame load is supported by the concrete portion 14 of the connection structure 10 and the concrete portion 22 of the column 20, and no axial compressive force acts on the short column steel 11 and the long column 21. By filling the gap g with the molten welding steel, the lower end of the short column steel frame 11 and the upper end of the long column steel frame 21 are closed in a state where no axial compressive force acts on the short column steel frame 11 and the long column steel frame 21. Can be joined. Accordingly, welding can be performed at a stage where a load due to the weight of the upper frame does not sufficiently act on the bonded portion. In addition, the upper and lower end surfaces of the concrete portion of the connection structure 10 and the column 20 are formed in advance so that axial force does not act on the short column steel frame and the long column steel frame in a state where these end surfaces are pressed against each other. deep. The upper part of the connection structure 10 and the lower part of the column 20 are connected to the connecting sleeve 24 and the connecting steel rod 2.
3, after a predetermined load due to the weight or the like of the upper skeleton is applied to the joint portion, the upper end of the short column steel frame 11 and the lower end of the long column steel frame 21 are firmly joined by welding or the like. . Also in this case, the end face around the concave portion 14a at the upper part of the concrete part of the joint structure 10 and the end face around the convex part 22b at the lower part of the concrete part of the column body 20 are pressed against each other, and the short steel column 11 Slant top surface 11a
A gap g suitable for welding is formed between the long steel column 21 and the inclined lower end surface 21b. In this state, the frame load is supported by the concrete portion 14 of the connection structure 10 and the concrete portion 22 of the column 20, and no axial compressive force acts on the short column steel 11 and the long column 21. By filling the gap g with the molten welding steel, the upper end of the short column steel frame 11 and the lower end of the long column steel frame 21 are filled with no axial compressive force acting on the short column steel frame 11 and the long column steel frame 21. Can be joined. Since the column steel frame 21 of the column body 20 and the column steel frame of the connection structure 10 are joined in a state where no axial compressive force acts on the short column steel frame 11 and the long column steel frame 21, the building frame is constructed. Even if a large load acts on the building frame after the completion of the building, there is no fear that the column steel frame composed of the short column steel frame 11 and the long column steel frame 21 will buckle. The upper end of the column 20 and the lower end of the connection structure 10 are connected without using a connecting steel bar to which a tensile force is introduced, and the column 2
0 and the lower end of the connection member 10, the upper end of the long column steel frame 21 and the lower end of the short column steel member 11 may be welded, or the upper end of the connection member 10 and the column member may be welded. The lower end of the long column steel frame 21 may be welded to the upper end of the short column steel frame 11 after the lower end of the column steel plate 20 is pressed into contact with the lower end of the column steel bar 20 using a connecting steel bar to which a tensile force is introduced.
