Description

Movable portal and prefabricated cabin top construction method

Technical Field

The invention belongs to the technical field of prefabricated cabins, and particularly relates to a movable portal and a prefabricated cabin top construction method.

Background

The preparation of self-contained cabin units brings great economic benefits to the shipbuilding plant, with the attendant safety risks of the cabin unit assembly process. Workers can only climb the vertical ladder to reach the top of the cabin unit and stand on the ceiling at the top of the cabin unit for construction operation, and potential safety hazards exist in the construction process of the workers. Without the support of corresponding tools, the following problems and defects exist in the construction process of the top of the cabin unit by workers:

(1) potential safety hazards caused by unstable placement of the ladder exist in the process of climbing the vertical ladder by workers;

(2) workers construct safety belts on the tops of the cabin units without stress points, and safety hooks can be hung everywhere;

(3) workers need to step on the ceiling reinforcing structure during construction at the top of the cabin unit, and the ceiling reinforcing structure and the ceiling may deform;

(4) the construction projects at the top of the cabin unit are more, and the construction efficiency of workers caused by the construction environment is low.

Although there are various improvements to the prior art, for example, CN201120365686 discloses a movable ladder, which comprises a bottom plate, handrails, ladder steps and the like, wherein the ladder is in a bilateral symmetry form, the bottom plate is arranged in the middle of the ladder, the bottom plate is supported by supporting legs, the supporting legs are stabilized by supports, the ladder steps and the bottom plate are connected by hinges, the dismountable handrails are respectively arranged on two side surfaces of the ladder steps and the bottom plate (1), and pulleys are arranged at one ends of the ladder steps and the supporting legs, which are in contact with the ground. The pulley under the ladder rung and the supporting leg in the proposal can ensure that the whole ladder can be moved to a required place at any time. The mounting of the base plate allows multiple persons to stand on the ladder at the same time. The handrails on the ladder rail and the bottom plate can be detached and folded at any time, so that the ladder is more convenient to use. However, the ladder of this solution is complicated in structure and presents a support structure, so that there is no place to accommodate the prefabricated cabin, which cannot be used for the construction of prefabricated cabin units.

In the construction and cable laying process of the cabin unit top framework piece, no corresponding tooling facilities are provided for better working conditions and safety guarantee for constructors.
