Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, in particular to a prestressed concrete steel tube truss composite plate supporting device. Background Art

[0002] A prestressed concrete steel tube truss composite slab is a structural component composed of prestressed concrete tubes, steel bars, and steel trusses. This structure effectively utilizes the high strength and prestressing properties of concrete while also fully utilizing the stiffness and seismic performance of the steel tubes. Therefore, prestressed concrete steel tube truss composite slabs are widely used in large public buildings, stadiums, high-rise residential buildings, and other fields.

[0003] With the rapid development of my country's economy, the construction speed of high-rise buildings is accelerating. This has made traditional building materials such as traditional wooden beams and steel beams gradually unable to meet the growing construction needs. The strength and durability of traditional building materials also limit the stability and safety of building structures. Therefore, a prestressed concrete steel tube truss composite plate support device is needed to support the composite plate. In actual application, existing prestressed concrete structures often need to rely on a large amount of steel bars or other reinforcement measures to improve their stability, which not only increases construction costs, but also brings many inconveniences to construction. In addition, the support devices of existing prestressed concrete steel tube truss composite plate support devices usually adopt a fixed connection method, which consumes a lot of time when installing and disassembling the support device, thereby reducing the installation efficiency of the device.
