| (57) A method is provided of erecting an arch-like structure comprising means (12), base
plates (14), connectors (16) and purlins (18) or cross bracings. The method involves
attaching a first beam (12a) to the base plate (14) by means of a first bolt (20)
only with the beam (12a) lying on the ground. The end of the first beams (12a) is
lifted sufficiently to allow the connection thereto of the second beam (12b) and this
process is repeated with subsequent beams (12c) through to the last beam (12d). The
whole operation is carried out on the ground and the arch rises into the air. A connector
is described as is a base connector. A beam including a box section on either side
of a profiled web is described along with variations thereof and a light weight structure
which can be converted to a trailable vehicle and which includes the principle of
the invention is also described. |
