Technical Field

[0001] The utility model relates to the technical field of elevator shafts, and particularly relates to a supporting structure for a cast-in-place structure of a suspended elevator shaft. Background Technique

[0002] With the acceleration of the modern urbanization process, high-rise buildings are increasing day by day. As an important tool for vertical transportation, the installation quality and efficiency of elevators are crucial to the progress and safety of the overall construction project. As the basic structure for elevator installation, the supporting method of the cast-in-place structure of the elevator shaft directly affects the construction quality and efficiency. In recent years, earthquakes have occurred frequently across the country. To ensure the safety of people's lives and property, most buildings have begun to adopt seismic isolation technology in large quantities, disconnecting the main structure and the foundation horizontally to achieve the purpose of "the ground shakes but the house doesn't move" or "the ground shakes greatly but the house shakes slightly" during an earthquake. To achieve the above purpose, the elevator shaft is designed with a suspended structure and is located in the elevator pit.

[0003] The existing supporting methods for the cast-in-place structure of the suspended elevator shaft are generally carried out by casting in place. The cast-in-place shaft not only has a long construction time but also consumes a large amount of manpower and material resources, reducing work efficiency. Moreover, due to the excessive structural load and the limited surrounding narrow space of the suspended elevator shaft structure, the conventional steel pipe support formwork system cannot be used for support, resulting in poor support effect for the elevator shaft. Therefore, corresponding improvements are needed. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a supporting structure for a cast-in-place structure of a suspended elevator shaft to solve the problems of single support method, poor effect, and inconvenient disassembly in the use of the existing supporting structure for the cast-in-place structure of the suspended elevator shaft as mentioned in the above background technique.

[0008] Preferably, the supporting sand barrel is composed of a supporting upper barrel, a supporting lower barrel, an upper steel plate and a lower steel plate. The supporting upper barrel and the supporting lower barrel are buckled with each other. The bottom end of the supporting upper barrel is welded with the upper steel plate, and the top end of the supporting lower barrel is welded with the lower steel plate.

[0009] Preferably, a flexible partition is provided inside the supporting upper barrel, the interior of the supporting upper barrel is filled with concrete, and the interior of the supporting lower barrel is filled with standard.

[0010] Preferably, a plurality of groups of leakage holes with circular cross-sections are evenly arranged on the supporting lower barrel, and the leakage holes penetrate the lower steel plate.

[0011] Preferably, eight supporting sand buckets are provided, and the cross-section formed by the eight supporting sand buckets is a rectangle.

[0012] Preferably, the inside of the supporting base plate is evenly fixed with first reinforcing ribs and second reinforcing ribs, multiple groups of the first reinforcing ribs and second reinforcing ribs are arranged in the supporting base plate, the first reinforcing ribs and second reinforcing ribs are distributed in upper and lower layers in the supporting base plate, and the first reinforcing ribs and second reinforcing ribs form a mesh structure.
