PURPOSE:To easily construct for a short period the title shelter and to improve economical characteristic by previously manufacturing a symmetric snow shelter having a hinge arch of a peak shape 3 and a specific configuration and assembling it in the field. CONSTITUTION:A unit panel 1 (piece) for forming the snow shelter of a hinge arch structure 3 is previously manufactured which has a dimension in the length direction of of length as a unit length and a circular arc shape of substantially 1/4 of a circumference in a circumferential direction orthogonal with a line. The bases 3 of the shelter are constructed at both the sides of a predetermined line and a track is temporarily provided in the inside thereof. At the top, an elevating jack 21 is provided. A working carriage 5 capable of running on the track 4 is used to fix the respective leg parts of a pair of symmetrical pieces 1 on the bases 3. The top is connected through the jack 21 and a connecting part to an adjacent panel is connected to lower the jack 21, move the working carriage 5, sequentially repeat these operations and construct the snow shelter. |
