[0024] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific embodiments of the present application will be described in detail below with reference to the drawings.
[0025] like Figure 1 The hollow floor slab core mold shown is a cylindrical multi-cell floor slab core mold, which includes multiple cylindrical core molds 1 arranged in parallel. The multiple cylindrical core molds 1 are connected by a connecting part 2. Each cylindrical core mold 1 includes a first shell and a cavity disposed in the first shell. The connecting part 2 between two adjacent cylindrical core molds 1 is respectively connected to the cavity of the cylindrical core molds 1 on both sides, so that the two adjacent cylindrical core molds 1 are interconnected.
[0026] It should be explained that the aforementioned connecting part can be located at one end, both ends, or the middle of two adjacent cylindrical core molds 1.
[0027] Specifically, the aforementioned multi-cylinder floor slab core mold can be a combination of two cylindrical core molds 1, or a structure of three, four, or five cylindrical core molds 1. During production, gas is blown into the first shell through an air inlet on one side, causing the first shell to expand and form a cylindrical core mold 1. Then, through the connecting part 2, the gas reaches the adjacent cylindrical core molds 1, forming a multi-cylinder floor slab core mold. This production method is simple and efficient, and it can ensure that the connecting part 2 between multiple cylindrical core molds 1 is connected to the cavity of the cylindrical core mold 1, realizing the integrated design of multiple core molds.
[0028] During use, after the multiple floor slab core molds are laid on the floor slab, concrete is poured, so that the multiple floor slab core molds are filled in the concrete to form cavities. At the same time, the cylindrical core mold 1 design has better stress performance than the traditional square core mold, and can better resist the action of external loads, ensuring the safety and durability of the floor slab.
[0029] In this embodiment, the connecting part 2 at both ends can be a square structure, a circular structure, or a square structure at one end, a circular structure at the other end, or the same end of multiple parallel cylindrical core molds 1 can have both a square structure and a circular structure.
[0030] The design of the aforementioned connection part 2 can be flexibly selected according to specific usage requirements and construction conditions to meet the application needs in different scenarios.
[0031] In this embodiment, as Figure 2 and Figure 3 As shown, the cylindrical core mold 1 has a plurality of first protrusions 3 spaced apart on its outer side along the axial direction. The two outer first protrusions 3 form cylindrical portions on the cylindrical core mold 1, so that the cylindrical core mold 1 forms a structure in which rectangular portions and cylindrical portions are spaced apart along the axial direction. The rectangular portions and cylindrical portions together form the cavity.
[0032] Specifically, the first protrusion 3 in the structure can improve the overall hollow rate of the core mold floor, and the cylindrical structure can improve the stress stability of the entire core mold. Therefore, the cylindrical multi-cell floor core mold can ensure high hollow rate while significantly improving the overall strength and stability of the floor.
[0033] In addition, the inclined surface structure 31 of the first protrusion 3 can facilitate the demolding of the core mold structure during molding, thereby facilitating the production of the core mold structure.
[0034] In the embodiment, as shown in Figure 4 and Figure 5 The cylindrical core mold 1 is provided with a second protrusion 4 on the inner side in the axial direction, and the protrusion and the inner part of the cylindrical part jointly form the cavity.
[0035] Specifically, in the structure, the second protrusion 4 is designed on the inner side of the cylindrical core mold 1. The design of the second protrusion 4 can improve the overall hollow rate of the core mold floor, and the arc-shaped structure of the core mold is also retained. Therefore, the design of this structure can ensure the overall stability of the floor while reducing the use of concrete.
[0036] In the embodiment, as shown in Figure 6 The cylindrical core mold 1 is provided with a plurality of first protrusions 3 on the outer side in the axial direction, and the cylindrical core mold 1 is provided with a second protrusion 4 on the inner side in the axial direction. The first protrusion and the second protrusion and the inner part of the cylindrical part jointly form the cavity.
[0037] Specifically, the first protrusion 3 and the second protrusion 4 can improve the overall hollow rate of the core mold floor, and the arc-shaped structure of the core mold is also retained. Therefore, the design of this structure can ensure the overall stability of the floor while reducing the use of concrete.
[0038] In the embodiment, the plurality of cylindrical core molds 1 arranged side by side are integrally formed.
[0039] Specifically, the design of the integrally formed structure not only simplifies the production process, but also enhances the connection strength between the plurality of cylindrical core molds 1, making the overall structure more stable. In the production process, the plurality of cylindrical core molds 1 and the connecting part 2 can be integrally manufactured through one forming process, greatly improving the production efficiency and product quality. At the same time, the integrally formed structure also reduces errors and failures caused by multiple assemblies, improves the reliability and service life of the product.
[0040] In the embodiment, one end or both ends of the multi-cell floor core mold are provided with an inflatable air nozzle.
[0041] Specifically, the design of the inflation air nozzle 5 facilitates the inflation or deflation operation of the multi-twin floor core mold during production and use.
[0042] The above-described specific embodiments further specifically describe the purpose, technical scheme and beneficial effects of the present application, and it should be understood that the above-described specific embodiments are merely specific embodiments of the present application and are not intended to limit the present application, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
