Description

Technical Field

[0001] This invention belongs to the field of construction equipment technology, specifically relating to a mobile factory construction equipment and its usage method. Background Technology

[0002] Currently, the construction of cast-in-place concrete plant mainly adopts traditional steel pipe formwork construction. Traditional steel pipe formwork construction has the following drawbacks: complicated formwork erection steps, high labor input, large formwork size, high material consumption, plant construction formwork is mostly high-support formwork, which poses great safety hazards. At the same time, traditional steel pipe formwork construction has a long construction cycle, slow process interleaving, and low degree of industrialization.

[0003] Currently, cast-in-place concrete workshops have similar structural forms and modules. The workshop structure is a large-space frame structure with no structural obstructions in the middle, which facilitates the construction of large machinery and equipment. In the same project, there are many workshops with basically the same structure, and the length of a single workshop is over 100 meters. The workshop structure has the same repetitive components in the horizontal direction, which has the characteristics of industrialized assembly line construction. The cost of mechanical equipment construction is low and meets the requirements of industrialized mass production construction.

[0004] Therefore, developing a highly industrialized construction equipment that can replace traditional steel pipe formwork, reduce formwork material consumption, erection steps and labor input, improve factory construction efficiency, ensure on-site safety and civilized image, and integrate, modularize and recycle for factory construction is a challenge facing those skilled in the art.
