The utility model discloses a novel Z type purlin section reinforcing device, including main beam, Z type purlin, reinforcing part and fastener, Z type purlin is fixed on the main beam, and reinforcing part is detachably connected with connecting piece through fastener, and reinforcing part has the structure that matches with the section of Z type purlin, is used for being combined with Z type purlin and forms reinforcing. It is suitable for improving the bearing capacity and overall stability of Z type purlin structure, satisfies the demand of purlin enhancement in building roof reconstruction and new project. The device is simple in design, strong in adaptability, can reduce material use, optimizes construction process, significantly improves construction efficiency and economic benefits, and provides an efficient, economical reinforcing solution for steel structure building.

This disclosure relates to a hood assembly and a vehicle. The hood assembly includes a hood body and at least one lifting mechanism. At least one connection point is provided on the bottom surface of the middle portion of the hood body. The lifting mechanism is located below the hood body and corresponds to the connection point. The lifting mechanism is configured to rise and fall under preset conditions to contact or separate from the corresponding connection point. This hood assembly can meet the pedestrian protection requirements in the event of a collision, and also meet the rigidity requirements of the hood body in scenarios where pedestrian protection is not required. Furthermore, it eliminates the need for pop-up fulcrums or hinges, thus minimizing maintenance costs.
