A hanging basket for continuous beam construction
PendingCN122082364AImprove adaptive abilityHigh loading accuracyBridge structural detailsBridge erection/assemblyLow loadArchitectural engineering
This invention belongs to the field of continuous beam construction technology and solves the problems of large amount of high-altitude work, high safety risks, and low load accuracy in the existing hanging basket preloading test and ground tensioning preloading method. This invention provides a hanging basket for continuous beam construction, characterized by including a hanging basket, on which a template is installed, and a bottom basket is connected to the bottom of the template. The bottom basket is used to place counterweights. The bottom of the template is provided with a connector, and the top of the bottom basket is connected to a preloading box by steel strands. The top of the preloading box is provided with a hook, and a pair of lifting lugs are provided on both sides of the preloading box. The preloading box can be suspended by the hooks at the bottom of the connector by hoisting. This invention has the advantages of eliminating the need for high-altitude work during preloading, high safety, high construction efficiency, and high load accuracy.

Door structure and vehicle
ActiveCN224617400UOptimizing the force transfer pathGood force transmission effect
This application relates to the field of vehicle body technology and provides a door structure and a vehicle. The door structure of this application includes an inner door panel and a reinforcing unit disposed on the inner door panel near the exterior side. The reinforcing unit includes a window frame reinforcing plate disposed at the bottom of the window frame of the inner door panel, an inner panel reinforcing plate disposed at the bottom of the inner door panel, a central anti-collision beam disposed in the middle of the inner door panel, and a lower anti-collision beam disposed at the lower part of the inner door panel. The central anti-collision beam includes an outer anti-collision beam plate extending along the length direction of the inner door panel and an inner anti-collision beam plate disposed in the middle of the length direction of the outer anti-collision beam plate, and a cavity is formed between the inner and outer anti-collision beam plates. The door structure of this application can optimize the force transmission path of the door when impacted, improve the overall force transmission effect of the door, enhance the energy absorption effect and side-impact safety of the door, and help better protect occupants during a vehicle collision, thus improving the vehicle's safety performance.
