Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a pre-embedded sleeve assembly for air conditioning holes in shear walls. Background Technology

[0002] In current residential construction projects, especially during shear wall pouring, to avoid damage to the concrete structure caused by opening air conditioning holes later, pre-embedded devices are used to reserve air conditioning holes during the shear wall pouring process. During the reservation process, it is necessary to ensure that the positioning of the pre-embedded device is accurate and the slope is correct to ensure the later use effect.

[0003] In actual construction, the existing embedded devices are not easy to fix, which can easily cause positional deviation or incorrect slope. The construction of embedded devices is more complicated, the construction efficiency is low, the labor cost is high, and the materials cannot be recycled, which will cause a lot of financial waste.
