Description

Technical Field

[0001] This utility model relates to the field of precast concrete component molds, and in particular to an airbag combination mold for irregularly shaped precast concrete components. Background Technology

[0002] In the production of precast components, molds need to be designed and made according to the component drawings. The components are repeatedly produced through the molds. Conventional molds are mainly steel molds, but molds made of different materials such as aluminum molds, plastic molds, wooden molds, rubber molds, and fiberglass molds are also used.

[0003] Steel molds offer good economic advantages for standard components and large quantities. However, they are less suitable for complex shapes and small production runs. In such cases, rubber molds are typically used in conjunction. Rubber molds are used for surface textures, while wooden molds are generally used for smaller quantities to save costs. Each type of mold has its advantages and disadvantages. However, for the production of complex, irregularly shaped components, a better manufacturing method is needed while maintaining economic efficiency. To address the problems of high cost, low efficiency, and difficulty in achieving desired effects with irregularly shaped component molds, using airbags as the shaping material, combined with steel or wood, can effectively overcome these issues in the production mold construction. Summary of the Invention

[0004] The main objective of this invention is to propose an airbag assembly mold for irregularly shaped precast concrete components.

[0005] To achieve the above objectives, this utility model proposes an airbag assembly mold for irregularly shaped precast concrete components, comprising:

[0006] Vertical frames, which are spaced circumferentially along the axis:

[0007] The bottom airbag module is located on the inner side of the vertical frame. The bottom airbag module forms a closed-loop structure, and the middle part of the bottom airbag module forms a columnar filling area.

[0008] Elliptical tubes are located in the vertical frame. Two adjacent elliptical tubes are used to fix the two ends of the bottom airbag module, which plays a role in fixing, supporting and enclosing, forming a columnar filling area in the middle and the lower shape area of ​​the upper component.

[0009] The enclosure is located at the upper part of the two vertical frames, and the enclosure is attached to the upper wall of the bottom airbag module after inflation. The enclosure and the upper wall of the bottom airbag module form a platform filling area.

[0010] The top airbag has its upper outer periphery fitted against the upper inner wall of the vertical frame;

[0011] Connecting rings, three of which extend from the bottom airbag module to the top airbag, are used to form the upper circular holes of the prefabricated components.

[0012] In the actual design, the vertical frame and the surrounding panels serve as support and enclosure, and the bottom airbag module and the elliptical tube ring form the foundation column of the prefabricated component.

[0013] The upper structure of the prefabricated component is formed by the enclosure panels and the upper wall of the bottom airbag module.

[0014] The upper structure of the prefabricated component is formed by a top airbag, and the groove is provided with a through-hole in the shape of a connecting ring.

[0016] 1. Locate the floor plan and determine the position of each component;

[0017] 2. Dimensions and fabrication of the foundation columns;

[0018] 3. The dimensions and fabrication of the vertical frame, which then serves as the supporting skeleton for the bottom airbag module;

[0019] 4. Positioning and fixing of the vertical frame;

[0021] 6. Install the bottom airbag module and the upper enclosure of the oval tube;

[0022] 7. Install the bottom airbag module on the vertical frame, wherein the vertical frame is provided with a first positioning ring that mates with the sub-airbag;

[0023] 8. After the bottom airbag module is inflated, it is tightly integrated with the vertical frame;

[0024] 9. Install the second positioning ring for the top airbag to position the top airbag;

[0025] 10. Inflate the top airbag;

[0026] 11. The entire component consists of a bottom airbag module, a vertical frame, a surrounding panel, a top airbag, and a foundation column, forming an irregular structure. Concrete is injected between adjacent through airbags at the top to form an integral component.

[0027] 12. After the precast components are formed, the top airbag and bottom airbag modules are vented, and then the elliptical tube is removed, thus achieving demolding.

[0028] It mainly solves the problems of irregular shapes and a small number of customized components. It can be cast as a whole, and is easy to assemble and disassemble. It has the advantages of convenient molding, high efficiency, saving mold costs, improving quality, and recyclable airbags. Attached Figure Description
