  TECHNICAL FIELD The present invention relates to a joining structure and joining method of rod-shaped steel members for arranging a pair of rod-shaped steel members in a straight line and joining the ends thereof.

  Conventionally, rod-shaped steel members such as H-shaped steel having an H-shaped cross-section have been used as skeleton members of buildings. This type of rod-shaped steel member is usually cut at an appropriate length so that it can be easily transported, and at the work site, a plurality of rod-shaped steel members are arranged in a straight line as necessary, and the ends are connected to each other. By joining, one long rod-shaped steel member is formed (for example, refer to patent documents 1).

  FIG. 11 is a perspective view showing a conventional method for joining rod-shaped steel members 301. FIG. 11 shows a case where a pair of rod-shaped steel members 301 each having an H-shaped cross section are joined as an example of the rod-shaped steel members 301. These rod-shaped steel frame members 301 have a pair of parallel plate portions 311 extending in parallel to each other and a vertical plate portion 312 extending in a direction perpendicular to the parallel plate portions 311 and connecting the central portions of the parallel plate portions 311 to each other. Are integrally formed.

  As a method for joining the end portions, a method using a connecting plate 304 as shown in FIG. 11 is common. More specifically, by arranging a pair of rod-shaped steel members 301 in a straight line, the corresponding parallel plate portions 311 and vertical plate portions 312 are held so as to extend in the same plane. The connection plates 304 are bridged between the parallel plate portions 311 and between the vertical plate portions 312, and the connection plates 304 are connected between the parallel plate portions 311 and the vertical plate portions 312, respectively, such as bolts (see FIG. (Not shown).

  When connecting a plurality of rod-shaped steel members 301 in a straight line in the vertical direction, in order to adjust the length of one rod-shaped steel member formed after the connection, a pair of rod-shaped steel members 301 adjacent to each other are As shown in FIG. 11, there is a case where the end portions are joined in a state where a predetermined interval C is formed.

In a formed state, it can be held in a straight line. Therefore, joining operation | work can be easily performed by joining the edge parts of each rod-shaped steel frame member in this state. In particular, not only the end surface of each rod-shaped steel member but also the end surface member coupled to each end surface can be brought into contact with the insertion member to sandwich the insertion member, so that the insertion member can be stably disposed. .

  A method for joining rod-shaped steel members according to a fourth aspect of the present invention includes a rod-shaped steel member arrangement step in which the pair of rod-shaped steel members are arranged in a straight line in the vertical direction so that the end surface members come into contact with each other. The member insertion step is characterized in that the pair of rod-shaped steel members are separated from each other, and the insertion member is inserted between the rod-shaped steel members, thereby sandwiching the insertion member between the end surface members.

  According to such a configuration, before inserting the insertion member between the end surface members, the pair of rod-shaped steel members are arranged in a straight line in the vertical direction, and the end surface members are coupled to the end surfaces of the respective rod-shaped steel members. A pair of rod-shaped steel members can be stably held by bringing them into contact with each other once. Therefore, it is not necessary to hold the rod-shaped steel member for a long time in a state in which a gap is formed between the end portions during the joining work, and it is only necessary to insert each end portion apart at the time of insertion of the insertion member. The joining operation of the rod-shaped steel member can be facilitated.

  According to the present invention, by inserting the insertion member between the end surface members joined along the bent portion to each end surface of the pair of rod-shaped steel members, a space is formed between the end portions of these rod-shaped steel members. Since it can hold | maintain in a straight line in the state which joined, the joining operation | work can be easily performed by joining the edge parts of each rod-shaped steel frame member in this state.
