[0062] The longitudinal connecting rod 1-4 is formed by a fiber-reinforced composite material through a molding or pultrusion process, and the longitudinal connecting rod 1-4 is connected to the transverse connecting rod 1-1 at the intersection by a special joint, bonding or slotting.

[0063] The rear part of the folding roof 1 is provided with a drainage trough 1-5 along the outer side of the transverse connecting rod 1-1 to collect rainwater from the roof. The lowest point of the drainage trough 1-5 is connected to a vertically arranged drainage riser 1-6 so that the rainwater collected by the drainage trough 1-5 can be discharged to the rainwater system in the field through the drainage riser 1-6.

When the folding roof 1 is basically unfolded, the lifting cable winch 5-4 is rotated to make the lower end of the movable strut 5 continue to move upward along the slide groove 5-1 under the action of the lifting cable 5-2, so that the folding roof 1 is fully opened. Thereafter, the lifting cable winch 5-4 is locked, and the lower end of the movable strut 5 is fixed to the slide groove 5-1 with a pin.

[0072] When the hangar is folded, first the lifting cables 5-2 are loosened to move the movable struts 5 downward, so that the folding roof 1 is ready for folding. Then the tractor 7 moves backward to drive the two movable side walls 2 to move toward each other, so that the folding roof 1 can be quickly folded horizontally. Finally, after the folding roof 1 is folded into place, the running wheels 3 at the bottom of the movable side walls 2 are locked, and the balancing cables 7 and the stabilizing cables 6-4 are loosened to complete the folding of the hangar.

[0073] like Figure 6 As shown, the structure of the second embodiment of the mobile folding hangar that can be expanded and folded laterally of the present invention is substantially the same as that of the first embodiment, except that the adjacent hangars share the mobile side walls 2 to achieve the row-and-row use of multiple folding hangars.
