Connectors between frame elements of a temporary canopy, and methods for connecting frame elements.

Abstract

Conventional temporary structures suffered from weak connections between frame elements and poor workability. [Solution] The connector between frame elements consists of a joint pin connecting adjacent first and second frame elements, a bolt connecting the first and second frame elements, and a brace provided between the first and second frame elements. Each frame element is formed in a frame shape by two parallel steel pipes and a beam connecting the two steel pipes. The joint pin is inserted into one end opening of the first frame element and the other end opening of the second frame element, respectively. The bolt is inserted into bolt holes in plate pieces formed at the ends of one of the first and other steel pipes of the first frame element, respectively, and into bolt holes in plate pieces formed at the ends of the other steel pipes of the second frame element, respectively, and the elements are connected by tightening nuts.

[0017] As shown in Figures 1 to 3, the connector between the frame elements of the erected shed of the present invention comprises a joint pin 8 that connects the adjacent first frame element 3a and second frame element 3b, a bolt portion that connects the first frame element 3a and the second frame element 3b, and a brace 9 provided between the first frame element 3a and the second frame element 3b.

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

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

[0020] The joint pin 8 is inserted into the one end openings 10a, 10a of the one and the other steel pipes 1, 1 of the first frame element 3a, and the other end openings 10b, 10b of the one and the other 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 bolt portion described above is constituted by, for example, a bolt 11 and a nut 12. The bolt 11 is inserted into the bolt hole 14a of the plate piece 13a formed by welding or the like at one tip of each of the one and the other steel pipes of the first frame element 3a, and the bolt hole 14b of the plate piece 13b formed by welding or the like at the other tip of each of the one and the other steel pipes of the second frame element 3b, and the nut 12 is tightened, whereby the first frame element 3a and the second frame element 3b are connected to each other.

[0022] Further, the brace 9 described above has holes formed at both ends respectively, and the bolt 16 is inserted into each of the holes, the first hole for brace engagement provided in the plate piece 15a formed by welding or the like at one end of each of the one and the other steel pipes 1 of the first frame element 3a, and the second hole for brace engagement provided in the plate piece 15b formed by welding or the like at one end of each of the one and the other steel pipes of the second frame element 3b, which faces the first hole obliquely, and is tightened and connected by a nut.

[0023] Note that, as shown in FIG. 1, the brace 9 described above may be a single diagonal brace in addition to two crossed braces.

[0024] Since the connector between frame elements of the present invention is configured as described above, first, a plurality of frame elements 3 having a required shape are produced on site.

[0025] Then, these frame elements 3 are brought to the site, the plurality of frame elements 3 are arranged in the axial direction of the steel pipe 1 respectively, joint pins 8 are inserted and connected between the one and the other end openings 10a, 10b of each adjacent frame element 3, 3 respectively, the bolt 11 is inserted into the bolt hole 14a and the bolt hole 14b and tightened with the nut 12, and the holes of the brace 16 are overlapped with the first hole and the second hole respectively, the bolt 16 is inserted and tightened and fixed with a nut, thereby forming the frame of the temporary shed.

[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]
