Along with the continuous development of society, the pace of life of people is continuously accelerated, and the construction period requirements of the building industry are also continuously improved, so that new challenges are brought to the construction technology. The cast-in-situ structural slab in the field of building construction often has the condition of two layers or even three layers of continuous pouring, especially the floor layer height is too high, so that three or four running of stairs of one layer exist, the problem is brought to the erection of a formwork support system under the condition, and the technical problems of construction period, erection and dismantling of the formwork support and the like are considered. So the mould frame system scheme for continuous casting of the multilayer structure plate is always a technical problem of a construction unit.
In order to realize saving in construction period and cost, taking continuous casting of two-layer structural plates as an example, the prior solution is generally as follows:
one is to directly pass the formwork support pole setting through the first layer of structural slab formwork, lay the second layer of formwork after reaching the upper layer of structural height, and then ligate each layer of structural steel bars. The problem that this scheme exists lies in, want the convenient dismantlement of template support pole setting, must every pole setting set up the sleeve pipe when wearing first layer structure board, need mend the hole one by one after pouring like this, if do not set up the sleeve pipe then need cut off the steel pipe, then mend the hole one by one, no matter set up the sleeve pipe, both can increase a large amount of human costs, and the latter still can improve turnover material's loss rate. Another disadvantage is that the solution requires holes in the form, which not only increases labor costs, but also reduces the number of turnover uses of the form, further increasing costs.
