[0010] 1. Good molding appearance, high durability and easy installation and disassembly.

[0011] 2. No need to install air ducts. The air shaft is fully concrete-formed to avoid masonry after the air ducts are installed, which plays a key role in the fast insertion system.

[0012] 3. Reduce the workload of wet operations, save energy and protect the environment.

[0013] 4. It eliminates the generation of reserved openings for air shafts from the root, reduces the sources of danger on the construction site, reduces the number of construction safety accidents caused by reserved openings, and ensures better construction safety.

[0014] 5. Fewer construction processes reduce the construction waste generated by secondary construction and improve the overall civilized image of floor construction. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] See also Figure 1-Figure 3 As shown, the technical solution adopted in this specific embodiment is: it includes an aluminum film outer mold 1 and an aluminum film inner mold 4, a concrete layer 3 is provided between the aluminum film outer mold 1 and the aluminum film inner mold 4, and the adjacent ends of the aluminum film outer mold 1 and the aluminum film inner mold 4 are fixedly connected by a reinforcing screw 2, the other end of the aluminum film inner mold 4 is installed on the wall, and an inner mold release agent layer 5 is provided under the aluminum film inner mold 4, and an exhaust louver assembly 7 is installed at the opening of the concrete layer 3.

[0021] More specifically, a plurality of reinforcing screws 2 are provided, and penetrate and connect the aluminum film outer mold 1, the aluminum film inner mold 4 and the wall. By using the reinforcing screws 2 for connection and reinforcement, the stability between the aluminum film inner mold 4 and the aluminum film outer mold 1 and the wall is ensured, which is convenient for subsequent construction.

[0022] To be more specific, an aluminum film C groove 6 is installed at the connection between the aluminum film outer mold 1 and the inner mold release agent layer 5, and an aluminum film C groove 6 is installed at the lower side of the wall.

[0023] More specifically, the corners of the aluminum film inner mold 4 are chamfered, and a hook is added to the top of the aluminum film inner mold 4, so that the aluminum film inner mold 4 can be easily removed.

[0024] More specifically, the connection between the aluminum film inner mold 4 and the aluminum film C groove 6 is arranged in a stepped shape. The stepped shape can be conveniently buckled with each other, so as to facilitate the reinforcement of the aluminum film outer mold 1 and the aluminum film inner mold 4.

[0025] The working principle of the utility model: it includes the following specific manufacturing processes: installing the base reinforcement: 4φ18mm reinforcements are reserved at the bottom of the inner wall of the wind shaft as the base to prevent the inner mold from falling when it is assembled and hoisted; assembling the aluminum film inner mold 4: assembling 4 pieces of double-oblique aluminum molds with R corners and 8 pieces of straight double-oblique aluminum molds according to the aluminum mold deepening drawing, and applying the inner mold release agent layer 5; hoisting the aluminum film inner mold 4: the assembled aluminum film inner mold 4 is a barrel-shaped aluminum mold with a prefabricated hook on the top. It is hoisted as a whole with a tower crane in conjunction with the inner mold, placed on the base reinforcement, and temporarily stabilized to prevent overturning; installing the aluminum film outer mold 1: before installing the aluminum film outer mold 1, it is necessary to first tie the flue wall reinforcement and install the inner support sleeve. The mold can be sealed only after acceptance. The template surface must be cleaned before sealing the mold. And evenly apply the inner mold release agent layer 5; install the reinforcement screw 2: after the installation of the aluminum film outer mold 1 is completed, buckle the back rib, pass the reinforcement screw 2 to the reinforcement screw 2 reserved on the opposite aluminum film inner mold 4 to tighten and reinforce. The reinforcement screw 2 needs to be inspected to expose the thread head to avoid loose reinforcement and mold burst; pouring of concrete layer 3: after the reinforcement is completed, pour the concrete, pay special attention to the bottom vibration to avoid loose pouring, and the bottom should not be over-vibrated to cause the reinforcement screw 2 to loosen and burst; demolding: demold as soon as possible to ensure that the surface edges are not damaged. When the strength reaches 1MPa, the aluminum film outer mold 1 and the aluminum film inner mold 4 can be removed in about 6 to 8 hours; install the exhaust louver assembly 7, among which the specific process of demolding is: back rib removal → aluminum film outer mold 1 removal → aluminum film inner mold 4 top pin removal → aluminum film inner mold 4 removal.

[0026] The above is only used to illustrate the technical solution of the utility model rather than to limit it. Other modifications or equivalent substitutions made to the technical solution of the utility model by ordinary technicians in this field should be included in the scope of the claims of the utility model as long as they do not depart from the spirit and scope of the technical solution of the utility model.
