[0018] Each of the frame elements 3 is formed, for example, in a frame shape by connecting two parallel steel pipes 1 and 1 on one side and the other side by a plurality of beams 2 and 2 by welding or the like.

[0019] In addition, the beam 2 on the most end side of the adjacent first frame element 3a and the beam 2 on the most other end side of the second frame element 3b are provided at the inner end portion from the tip end portion of each frame element 3 so that a brace 9 can be provided between the beam 2 on the most end side of the first frame element 3a and the beam 2 on the most other end side of the second frame element 3b when the first frame element 3a and the second frame element 3b are connected.

[0020] The joint pin 8 is inserted into the one - end openings 10a, 10a of the one - side and the other - side steel pipes 1, 1 of the first frame element 3a and the other - end openings 10b, 10b of the one - side and the other - side steel pipes 1, 1 of the second frame element 3b, respectively, so that the first frame element 3a and the second frame element 3b are connected.

[0021] The above bolt portion is composed of, for example, a bolt 11 and a nut 12. The bolt 11 is inserted into bolt holes 14a of plate pieces 13a formed by welding or the like to one tip end portion of one side and the other side of the steel pipes of the above first frame element 3a, and bolt holes 14b of plate pieces 13b formed by welding or the like to the other tip end portion of one side and the other side of the steel pipes of the above second frame element 3b, respectively. By tightening the nut 12, the above first frame element 3a and the above second frame element 3b are connected.

[0022] Further, holes are respectively formed at both end portions of the above cross brace 9. The bolt 16 is inserted into each of the holes, first holes provided for cross brace engagement formed in plate pieces 15a formed by welding or the like to one end portion of one side and the other side of the steel pipes of the above first frame element 3a, and second holes provided for cross brace engagement formed in plate pieces 15b formed by welding or the like to one end portion of one side and the other side of the steel pipes of the above second frame element 3b which are diagonally opposed to the first holes, and tightened with nuts to be connected.

[0023] As shown in FIG. 1, the above cross brace 9 may be composed of two crossed ones and one diagonal one.

[0024] Since the connector between the frame elements of the present invention has the above-described configuration, first, a plurality of frame elements 3 having necessary shapes are created on site.

[0025] Then, those frame elements 3 are brought to the site, and the plurality of frame elements 3 are arranged in the axial direction of the steel pipes 1 respectively. Joint pins 8 are inserted and connected between the one and the other end openings 10a, 10b of each adjacent frame elements 3, 3. At the same time, bolts 11 are inserted into the bolt holes 14a and the bolt holes 14b and tightened with nuts 12. Further, the holes of the cross brace 16 are respectively overlapped with the first holes and the second holes, bolts 16 are inserted and tightened with nuts to form a frame of a temporary upper house.

[0026] Furthermore, some or all of the multiple frame elements 3 may be manufactured by connecting them together at the factory.

[0027] According to the present invention, since turnbuckles are not used, installation time is reduced compared to conventional methods.

[0028] Furthermore, by using bracing, the connection strength between frame elements 3,3 can be increased.

[0029] Furthermore, the units can be connected using only bolts, improving work efficiency on site. [Explanation of Symbols]
