Background

At present, in building construction, when concrete members such as floor slabs or beam bodies are cast on site, templates, traditional steel pipe supports, U-shaped jacking and the like are adopted for assembly. However, due to the technical limitation of the supporting system, the formwork needs to be dismantled with the concrete strength reaching more than 75%, and the time for setting the concrete is at least more than 20 days, so that at least 3 sets of materials such as the formwork, reinforced steel pipes, beam slab supporting ribs and the like are needed.

In order to shorten the form removal time, the construction unit adopts the common measures that a certain amount of additive is doped in ready-mixed concrete to improve the early strength of the concrete, so as to achieve the effect of removing forms in advance, or the early form removal is realized by using an early form removal support system construction method on some large-span plate supports, and the early form removal support system construction method is simple and easy to construct and operate aiming at a high-rise reinforced concrete structure, so that the effects of accelerating the turnover of the forms and saving investment are achieved;

The prior early dismantling technology realizes early dismantling of the formwork by respectively erecting the supporting frame and the early dismantling member at the bottom of the slab and the beam, and when in construction, a fixedly connected steel pipe is also required between the supporting columns for ensuring stability, the existing supporting columns and the connecting steel pipe between the supporting columns are usually fixed by bolts, when the early dismantling formwork is dismantled, the bolts are required to be screwed to firstly dismantle the connecting pieces between the supporting columns, then the bolts are required to be screwed to the high place to dismantle the supporting pieces close to the ceiling and enable the top ends of the supporting pieces to move downwards, the supporting columns can be removed from the floor formwork, and the early dismantling of the supporting columns becomes more troublesome.
