Description

Technical Field

[0001] The present application relates to the technical field of construction machinery and equipment, and in particular to a monorail mounting reaction hanger. Background Art

[0002] At present, in the construction process of tunnel invert side walls, most of them use channel steel or wooden boards and steel support to form the invert side wall formwork. This method is simple to operate and has a single process flow.

[0003] After searching, the Chinese patent application number: 201710805205.0 discloses an integral steel mold for a tunnel inverted arch side wall, including a steel mold body. The steel mold body adopts a welded steel frame structure with a closed ring cross-section, and the top surface, outer side surface and bottom surface of the steel mold body are covered with steel plates. The outer side surface contour matches the contour of the tunnel inverted arch side wall to be cast. Reinforcing steel supports are welded in the inner cavity of the steel mold body, and a number of waterstop hangers are welded at intervals along the extension direction of the steel mold body. The waterstop hangers are welded to the outer side of the top of the steel mold body and extend upward toward the outside. A waterstop clamp is installed under each waterstop hanger to fix the waterstop.

[0004] Regarding the above-mentioned related technologies, the inventors believe that there are the following technical defects that need to be improved:

If common construction hangers are laid in the entire tunnel, there will be a problem of high production costs. If common construction hangers are only laid in a small section of the tunnel, there will be problems such as inconvenience in movement and construction. Utility Model Content
