Abstract

The invention provides a formwork trolley release agent brushing device, including a fixing device and a release agent brushing system, the fixing device is detachably installed on the tunnel lining steel bar, and the release agent brushing system is located on one side of the fixing device. The release agent brushing system includes a support frame, one side of the support frame is connected with the fixing device, the other side of the support frame is provided with a roller, and the roller is covered with a brushing roller, which is used to lean against the outside of the steel formwork The surface is painted. The invention has ingenious structure, high performance and high reliability. It can be adjusted according to the diameter of the main reinforcement in the ring direction, and is suitable for various structures. It can be adjusted according to the distance between the formwork trolley and the steel bar to ensure that the brushing device is closely attached to the surface of the steel formwork. , so as to ensure the uniformity of the release agent brushing. It solves the defects that the template release agent in a limited space depends on the working window for spraying, uneven brushing, and easy to contaminate steel bars. At the same time, it improves construction efficiency and shortens the overall construction period.

Description

technical field [0001] The invention relates to the technical field of tunnel engineering construction equipment, in particular to a formwork trolley release agent brushing device and a working method. Background technique [0002] In the construction of underground projects such as tunnels, formwork trolleys are used for lining concrete construction. Before concrete pouring, it is necessary to apply a release agent to the surface of the steel formwork of the lining trolley to ensure the appearance quality of the lining concrete. At present, the large-scale lining trolley formwork release agent in the limited space such as the second lining formwork trolley of the tunnel generally adopts two methods of air pressure spraying and walking to the open section for manual brushing. The traditional way of spraying the release agent by the air pump mainly relies on the reserved working window on the formwork trolley, and has the following disadvantages: ① The release agent is not sp...
