Description

[0002] The use of prefabricated composite thermal insulation non-removable formwork at the full cast-in-situ concrete outer wall is a new material and construction technology. The prefabricated composite thermal insulation non-removable formwork is a prefabricated panel material with thermal insulation function and non-removable formwork function, which is composed of thermosetting composite polystyrene foam insulation board and phenolic foam board as core material, and the surface layer composed of polymer mortar and glass fiber mesh on both sides. The prefabricated composite thermal insulation non-removable formwork is a building thermal insulation and structure integrated system. The application of this construction technology and material not only saves the construction period of the outer wall thermal insulation, but also saves the investment of the outer wall formwork. However, the disadvantage is that the materials are standard size factory prefabricated, and due to the thickness of the materials, the use of prefabricated non-removable formwork cannot be reinforced for the small cross-section size structure of the outer wall eave modeling, and the component forming quality cannot be guaranteed.

[0003] Firstly, in terms of materials, workers will cut the whole prefabricated non-removable formwork into small size small cross-section short strips, and use wooden bars for simple fixation and reinforcement, which greatly reduces the construction efficiency;

[0004] Secondly, the short strip non-removable formwork reinforcement is limited by the space structure and cannot be smoothly, quickly and effectively reinforced and formed;

[0005] Thirdly, after pouring the concrete, the short strip non-removable formwork is difficult to guarantee the quality of the small cross-section eave modeling due to the side pressure of the concrete.

[0006] In summary, if the prefabricated non-removable formwork is used for the eave modeling part, the eave modeling part needs to be cut and chiseled to the concrete structure surface for secondary construction in the later stage, and the joint part in the later stage is prone to leakage and quality problems.
