Description

Technical Field

[0002] Construction takes a short time in the entire life of a building, but its impact on the environment is great, and the consumption of resources and energy is also very concentrated. In order to respond to the Ministry of Construction's call for green construction, in actual product use, we try to achieve more repeated use. The early dismantling formwork system is a support system including scaffolding and formwork for pouring concrete, reinforced concrete buildings or structures. It forms the bottom formwork of the pouring beam or slab by combining the top plate of the support column and the concrete beam and slab formwork. When the concrete of the beam or slab solidifies to a certain extent, the formwork is removed by the early dismantling mechanism. The pouring beam or slab can be completely removed when it is supported by the top plate of the support column to the concrete strength specified in the specification. The early dismantled formwork is used for layer transfer or site transfer to shorten or advance the construction period, improve the labor productivity of construction, and at the same time reduce the number of formwork inputs and reduce construction costs.
