PROBLEM TO BE SOLVED: To improve the usability of a folding tent. SOLUTION: Pins 14 for joints are dropped, penetrated and constituted among brackets 13 projected to upper and lower sections at the upper ends A of Warren trusses 12, in which pairs of upper and lower pipe chord materials 12a, 12b are converged from upper-end broad width A to lower-end narrow width B. The paired support joints of roof-truss end face bodies are formed by dropping legs 12e for the joints projected and drooped to the lower ends of the Warren trusses 12 to the upper ends of supports 17 made of pipes. Connection among building end-face frames is formed by dropping connecting materials 19 made of the pipes having drooped legs 19a for the joints at both ends to the upper-end vertical sides 12c of one Warren trusses 12 and short pipes 12d, 17a annexed at the upper end sections of the supports 17 among roof apices and the supports. The reinforcing sash bar-like connection of the intermediate section of an inclined roof is formed by dropping connecting members 20 made of the pipes having drawn brackets 20a at both ends in hook pins 16 for engaging sheets 15 and eyelets 15a to the top faces of the upper chord materials 12a of the Warren trusses 12.
