In this case, at least two frames are required, but the number of frames is further increased according to the area of the work area.

(2) Next, a plurality of purlins 8 are bridged at predetermined intervals in the longitudinal direction of the beams 5 between the beams 5, 5 of the opposing frame structures, and each purlin 8 is fixed to the beams 5. Then, the roof sheet 9 is put on the main building 8 to construct the temporary roof 6.

Thus, the assembly of the all-weather temporary roof is completed, but since the entire work area often cannot be accommodated by a single temporary roof, a plurality of buildings are constructed and used in combination. (See FIGS. 7 and 8).

(3) The water gradient of the roof is the fixed height of the column 1,
This is performed by appropriately adjusting the mounting positions of the beam 5 and the purlin 8.

(4) Next, in order to raise the temporary roof 6 as the frame work proceeds, the elevating device 3 is set on the column base of the column 1, and the ratchet wheel is engaged with the ratchet hole 1a of the column 1. (See FIGS. 3A, 3B, and 3C). In addition, this support 1
Is temporarily removed.

(5) Next, the lifting device 3 is driven to support
And a column 1A is added to the lower end of the column 1 at the same time (see FIGS. 4 (a) and 4 (b)). Further, the fixing device 4 is set again, and the column 1 is fixed again by the fixing device 4.

The operations (3) to (5) are performed for all the columns, and the temporary roof 6 is pushed up to a required height.

When the building is dismantled, the column 1 is lowered and the temporary roof 6 is lowered in parallel with the dismantling of the building.
Is lowered.
