A material joint connecting an internal spar or baffle to panel walls of inflatable structures. The material joint is formed by a folded center strip and a pair of side strips. The side edges of the center strip are folded to form an initial T-shaped cross-section having a middle section, two side sections formed by a first bend, and two overlapping end sections formed by a second bend. The middle section is fused directly to the facing surface of the panel wall and the overlapping end sections are fused together to extend perpendicularly from the middle section. The end strips overlap the center strip with part of the end strips fused to the side sections of the center strip and part fused directly to the panel wall. The spar or baffle is connected to the fused overlapping end sections of the center strip. Under the internal air pressure of the inflated structure, the side sections bow and arc under tension from the connected spar or baffle and the middle section acts as a bridge to lift and flatten the exterior surface of the panel wall across its width.

The present disclosure provides water sliding device. The water sliding device includes a sliding portion and a water spray apparatus. The sliding portion has a sliding surface suitable for a user sliding thereon, wherein a water pipe, which has a plurality of water spray holes, is disposed on the sliding portion. The water spray apparatus includes an outlet portion for spaying water and a water valve disposed between the outlet portion and a water source. Further, the water valve is configured to automatically restore to a closed state after being opened for a predetermined period of time, so as to make the outlet portion automatically stop spraying water. Accordingly, the water spray apparatus can automatically stop spraying water after a predetermined period of time, which can reduce water consumption and save water resource.
