Cast-in-place gentle-gradient spatial curved roof formwork system and construction method thereof

Abstract

The invention discloses a cast-in-place gentle-gradient spatial curved roof formwork system and a construction method thereof. The formwork system comprises a supporting structure and a panel structure; the supporting structure comprises a bottom all-round scaffold and a group of height-adjustable jacking and connecting assemblies, the number of the jacking and connecting assemblies is the same asthat of vertical rods, and the jacking and connecting assemblies are fixedly connected to the top ends of the vertical rods; and the panel structure is divided into a group of rectangular unit modules, each unit module comprises formwork keels, formwork panels and formwork connecting assemblies, the formwork connecting assemblies are fixedly connected to the four corners of each unit module, andthe formwork connecting assemblies of every four adjacent unit modules intersect at the same position and are located on the top of the same jacking and connecting assembly. The cast-in-place gentle-gradient spatial curved roof formwork system is suitable for a large-thickness curved roof of which the curvature change is irregular and the curved unit is approximately regarded as a plane and meetsthe designed curvature requirement. The construction method is high in operability, not only can meet the bearing force requirement, but also can be fitted with the curved surface curvature change, and has the very high market value.

Description

technical field [0001] The invention relates to a roof formwork system, in particular to a space curved surface cast-in-place structure roof formwork system and a construction method thereof. Background technique [0002] With the development of the times, the artistic requirements for architectural modeling in the field of architectural design are getting higher and higher, and various special-shaped structures emerge in endlessly. Various types of curved surfaces are also increasingly appearing in architectural roof modeling, such as steel trusses and membrane structures. Among them, the construction of the curved roof structure of cast-in-place concrete is the most difficult. [0003] The key and difficult points of the cast-in-place reinforced concrete curved surface structure lie in the formwork engineering and scaffolding engineering, how to use the formwork to fit the curvature required by the design, and how to erect the corresponding scaffolding, all of which great...

Problems solved by technology

[0004] The purpose of the present invention is to provide a kind of cast-in-place gentle slope space curved roof formwork system and its construction method, to solve the problems of high cost and low reusability in the formwork support mode of the existing curved roof structure curved surface custom formwork of reinforced concrete structure Poor technical problems, but also to solve the problem that using the curvature of the template itself to simulate the surface of the entire area cannot fit the surface with large curvature changes
