<p><P>PROBLEM TO BE SOLVED: To provide a width-changeable type expansion all-weather membrane shed which enables a connection angle between a beam material and a column material and a connection angle between beam materials to be set in accordance with a frontage between the column materials in an installation place, and which can be stored or transported by folding a building frame. <P>SOLUTION: In this width-changeable type expansion all-weather membrane shed 20, two column-beam joints 1 and 3 between the column material 4 and the beam material 5, and a beam joint 2 between the beam materials 5 constitute a hinge section which comprises a connecting plate 12 at the end of the column material 4 or the beam material 5, a fastening bolt 13 for fixation and a fastening bolt 14 for connection, so as to make the column material 4 or the beam material 5 for connection rotatable. The building frame is constituted by fixing the rotation of the column material 4 and the beam material 5 in each hinge portion in a state in which the connection angle between the beam material 5 and the column material 4 and the connection angle between the beam materials 5 are set in accordance with the frontage between the column materials 4 in the installation place. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
