As shown in fig. 1-7, the half-ring body 1A or the full-ring body 1B of the formwork 1 is applied to a building floor Aa or a shear wall Ab, after the formwork Ac support before the concrete of the building floor Aa or the shear wall Ab is cast in situ is completed, the half-ring body 1A or the full-ring body 1B is placed on the upper surface of the formwork Ac, and then the reinforcement work is performed on the upper surface of the formwork Ac around the half-ring body 1A or the full-ring body 1B. After the concrete pouring construction of the building floor Aa or the shear wall Ab is finished, the semi-ring body 1A or the full-ring body 1B and the building floor Aa or the shear wall Ab after the concrete is cured are combined into a whole to be bonded together without being detached.

In order to meet the environment-friendly requirement of building materials and increase the strength of the formwork 1, the building cementing material for the prefabricated hole support disassembly-free formwork of the building pouring component is a magnesium cementing material or a plant fiber cementing material.

In order to enhance the cementing and bonding effect between the outer surface of the construction casting component preformed hole supporting disassembly-free formwork shell and the construction component, the outer annular surface of the formwork shell 1 is provided with a bonding structure meshed with the casting slurry.

Specifically, as shown in fig. 8, the bonding structure is a plurality of concave points 1ab arranged on the annular outer surface of the half-ring body 1A or the full-ring body 1B of the formwork 1.

Specifically, as shown in fig. 9, the bonding structure is a plurality of protrusions 1ac disposed on the annular outer surface of the half-ring body 1A or the full-ring body 1B of the formwork 1.
