The detachable inner mold is wrapped and attached to the outer surface of the reinforcement cage 3, and the detachable mold is formed as a whole with the reinforcement cage 3 and the pouring mold shell 6 through the design of the connecting part, so that the structure has high strength after forming, and the detachable inner mold does not need to be removed, thereby eliminating the step of removing the inner mold in the traditional manufacturing process, and solving the problems of complicated process and difficult demolding when removing the inner mold in the prefabrication process of the hollow column or the composite column in the prior art. In addition, the detachable inner mold and the outer mold 2 are used, and four sides can be formed at one time, so that the construction period is short, the occupied site is small, the appearance defects can be reduced by using the integral forming mode, the workload and time waste caused by manual repair are greatly reduced, and the manufacturing cost is saved. In addition, the detachable inner mold is fixed to the outer surface of the reinforcement cage 3 through the connecting part of the connecting part, and welding or binding operations are not needed, which is beneficial to shorten the construction period.

[0033] It should be noted that the reinforcement cage 3 of the utility model includes longitudinal reinforcement 31 and stirrup 32 arranged on the longitudinal reinforcement 31.

[0034] As a preferred embodiment, the detachable inner mold is a steel wire mesh sheet 1.

[0035] In the embodiment, the steel wire mesh sheet 1 is wrapped and attached to the outer surface of the reinforcement cage 3, and plays the role of an inner formwork when pouring concrete, so that the steel wire mesh sheet 1 has the advantages of light weight, low price, and no need for auxiliary facilities such as support, thereby greatly shortening the construction period and saving cost. After pouring is completed, the steel wire mesh sheet 1 and the pouring mold shell 6 become an integral whole, and the steel wire mesh sheet 1 does not need to be removed, thereby eliminating the demolding process. In addition, the steel wire mesh sheet 1 is relatively rough, the pouring mold shell 6 and the concrete poured in the later stage are combined well, and the steel wire mesh sheet 1 does not need to be treated again.

[0036] Of course, in other embodiments, the detachable inner mold can also be a mesh cloth.

[0037] Specifically, the inner side and the outer side of the mesh cloth are formed as rough surfaces. In this way, the firmness of the combination of the concrete and the mesh cloth is increased.

[0038] In other embodiments, the detachable inner mold can also be a water-soluble cloth. By wrapping the reinforcement cage 3 with the water-soluble cloth, the water-soluble cloth can be melted after the pouring mold shell 6 is formed, thereby facilitating the pouring in the later stage.

[0039] As a preferred embodiment, the outer surface of the steel wire mesh sheet 1 is coated with a layer of mortar.

[0041] As a preferred embodiment, the connecting piece is a U-shaped piece 4, which includes a U-shaped fixed part 41 and a plate-shaped connecting part 42, which is vertically arranged on both sides of the open end of the U-shaped fixed part 41, the U-shaped fixed part 41 is fixedly connected to the longitudinal reinforcement 31 of the reinforcement cage 3, and the plate-shaped connecting part 42 extends into the pouring gap after passing through the steel wire mesh sheet 1.

[0042] In this embodiment, by fixing the U-shaped piece 4 on the longitudinal reinforcement 31 of the reinforcement cage 3, the steel wire mesh sheet 1 is fixed on the reinforcement cage 3 by means of the plate-shaped connecting part 42, and the plate-shaped connecting part 42 has a large pulling area, and the plate-shaped connecting part 42 is configured to be embedded in the pouring formwork 6, thereby ensuring the reliability and safety of the connection between the reinforcement cage 3 and the pouring formwork 6.

[0043] As a preferred embodiment, the steel wire mesh sheet 1 is provided with a through hole corresponding to the position of the U-shaped piece 4. In this way, the U-shaped piece 4 can be conveniently extended on the outer surface of the reinforcement cage 3.

[0044] As a preferred embodiment, the outer mold 2 includes a bottom plate 21 and two side plates 22 arranged on both sides of the bottom plate 21, and the two side plates 22 and the bottom plate 21 are connected in a rotatable manner.

[0045] In this embodiment, the bottom plate 21 and the two side plates 22 form an open-top outer mold cavity, and after the outer surface of the reinforcement cage 3 is wrapped with the detachable inner mold, the two are placed horizontally in the outer mold cavity, and a pouring gap is reserved between the inner side of the outer mold 2 and the outer side of the detachable inner mold. After assembly, concrete can be poured into the pouring gap, and after the concrete solidifies, the outer mold 2 can be removed to form a hollow column of the reinforcement cage 3. The rotatable connection between the side plate 22 and the bottom plate 21 facilitates later disassembly and simplifies the demolding process. By using the outer mold 2, four sides can be formed at one time, the construction period is short, the occupied area is small, and the appearance defects can be reduced by using the integrated forming method, which greatly reduces the workload and time waste caused by manual repair, and saves the manufacturing cost.
