Description

Technical Field

[0001] The invention relates to the technical field of prefabricated house construction, in particular to a longitudinal wall hoisting guide device for a prefabricated house. Background Art

[0002] The various components of prefabricated houses are prefabricated in the factory and then transported to the construction site for assembly to form a complete structure. It has the advantages of short production cycle, stable quality and high construction efficiency, so it has been widely used in recent years.

[0003] In the prior art, during the hoisting process of prefabricated components, a crane is used to hoist the concrete components to a preset position, and the workers below make adjustments before installing and fixing them. During the fixation of the exterior wall components, the concrete components will shake to a certain extent. Therefore, during the falling process, workers working at high levels are required to hold cables and wind ropes to pull the exterior wall structures for repeated adjustments to reduce the amplitude of the shaking and facilitate subsequent installation. In the process where the workers pull the exterior wall components by hand and direct the crane to rise and fall for installation, the whole process is highly dangerous, and the safety risk of high-rise workers is high.
