Technical Field
[0001] This utility model relates to the technical field of cast-in-place prefabricated houses with integrated insulation and formwork, specifically a cast-in-place prefabricated house with integrated insulation and formwork. Background Technology
[0002] Traditional exterior wall construction involves installing outer and inner formwork and support systems on scaffolding platforms and floor slabs after the steel reinforcement is tied. The inner and outer formwork, under the combined action of internal supports and tie bolts or flat irons, form a concrete pouring cavity. Once the concrete reaches the required demolding strength, the formwork and supports are removed. As is well known, traditional construction methods suffer from low efficiency and high labor intensity. With the rapid development of building formwork, non-removable formwork has emerged in recent years. This type of formwork is integrally formed with the poured concrete and does not need to be removed after completion, becoming part of the wall structure. If used as an exterior wall, it typically includes an insulation board on the inner side and a decorative layer on the outer side. This allows for the one-time forming of the decorative layer and insulation board, significantly reducing construction efficiency and improving the strength of the insulation board. Currently, insulation boards are generally bonded twice or simply composited.
[0003] In practice, problems such as low construction efficiency, high labor intensity, and easy detachment of insulation boards exist. For interior walls, insulation boards are often not needed. The cast-in-place wall can be directly spliced using a formwork-free template. After casting, the interior partition wall is formed. According to market research and testing, the existing formwork-free template has a problem: insufficient strength, weak adhesion of insulation boards, grout leakage, and water leakage occur during the actual splicing process. Based on this, a cast-in-place prefabricated formwork-free integrated insulation house is proposed to solve the above problems. Utility Model Content

The cast-in-place walls can be directly spliced using no-removal formwork. After the casting is completed, the interior partition walls are formed. According to market research and experiments, there is a problem with the existing no-removal formwork: insufficient strength, weak adhesion of insulation boards, grout leakage and water leakage are problems in the actual splicing process.
