The invention belongs to the technical field of fabricated house building engineering, and particularly discloses a prefabricated concrete thermal insulation composite wall and a preparation method thereof. The prefabricated concrete thermal insulation composite wall comprises an outer-leaf concrete wall plate, a thermal insulation plate and an inner-leaf concrete wall plate which are sequentially connected through split type connecting pieces, and each split type connecting piece comprises a stress main reinforcement; the stress main reinforcements are made of glass fiber reinforced plastic, at least one through hole is formed in each of the two ends of each stress main reinforcement, and the stress main reinforcements are detachably connected with anchoring parts through the through holes and used for enhancing the anchoring of the split type connecting pieces and the prefabricated concrete thermal insulation composite wall. According to the prefabricated concrete thermal insulation composite wall, the split FRP connecting pieces are adopted, installation quality control in the production process of the composite wall is facilitated, disturbance is not likely to be caused through reinforcement steel bars and the wall plates, anchoring performance is remarkably improved, the production quality of the wall plates is guaranteed, installation efficiency is high, manufacturing cost is low, and the prefabricated concrete thermal insulation composite wall is suitable for application and popularization.
Description
Technical field [0001] The present invention belongs to the technical field of assembly housing construction engineering, and more particularly to a prefabricated concrete insulation composite wall and its preparation method thereof. Background technique [0002] In recent years, construction industrialization has become the development trend of construction industries due to low cost, good performance and energy-saving and environmental protection. The pre-concrete insulation wall is an important part of the construction of full-installed building. Because of its three functions, envelopes and insulation, it has a very broad application prospect. The prefabricated concrete insulation wall is mainly divided into three layers of outer-leaf concrete wall panels, intermediate insulation layers and end-leaved concrete wall plates. The insulation layer is located between two concrete wall boards, which is not easy to be affected by the external environment, with excellent Fire prevent...
