[0002] The core mold is a built-in filling body used in cast-in-place concrete hollow floor slabs. The core molds are buried regularly in the cast-in-place concrete hollow floor slabs. After pouring concrete on site, a cavity floor slab structure can be formed, which makes the cast-in-place concrete hollow floor slab have excellent performance, such as good heat insulation, sound insulation, thermal insulation effects and excellent earthquake resistance and load-bearing resistance. At the same time, it can also reduce the dead weight of the floor slab, reduce high-energy consumption materials such as steel bars and concrete, and save non-renewable resources such as sand and stone.

[0003] When the core mold in the prior art is used to fill the floor slab, the core mold is usually supported by cement blocks or bricks. The support strength of this support method is insufficient, which easily leads to poor stability of the core mold. The existing core mold solves this problem by providing support feet on the shell, and the support feet and the core mold are an integrally formed structure. This structure cannot adjust different support heights according to construction requirements. Utility Model Content

[0022] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0023] like Figure 2 As shown, an embodiment of the present application provides a hollow floor core mold with supporting feet, including a hollow floor core mold and a plurality of supporting feet 3, the hollow floor core mold includes at least two core mold bodies 1, the core mold body 1 includes a shell 11 and a hollow inner cavity, two supporting bodies 2 are symmetrically arranged between adjacent core mold bodies 1, a cavity is arranged in the supporting body 2, and the cavity is interconnected with the inner cavities of two adjacent core mold bodies 1, and two card slots 111 are symmetrically arranged on the shell 11.

[0024] like Figure 1 As shown, the supporting foot 3 includes a clamping portion 31 and a supporting portion 32 . The clamping portion 31 is fixedly connected to the supporting portion 32 . The clamping portion 31 is clamped with the clamping groove 111 . The supporting portion 32 is used to support the core mold body 1 .

[0025] Specifically, during the construction process, the hollow floor includes a bottom formwork, a bottom plate 321 steel bar and a top steel bar. The bottom plate 321 steel bar and the top steel bar are both mesh structures. The core formwork of the hollow floor is placed between the bottom plate 321 steel bar and the top steel bar. The supporting foot 3 passes through the bottom plate 321 steel bar and abuts against the bottom formwork.

[0026] Two core mold bodies 1 can be provided, and the two core mold bodies 1 are respectively detachably connected with four support legs 3, and the shells 11 of the two core mold bodies 1 are respectively provided with four card slots 111, and the card connection parts 31 of the support legs 3 are card-connected with the card slots 111 on the shell 11, and the support parts 32 of the support legs 3 pass through the bottom plate 321 steel bars and abut against the bottom template, so that the four support legs 3 support the two core mold bodies 1. The two ends of the opposite sides of the two core mold bodies 1 are connected by the support body 2, and the cavity of the support body 2 is connected with the inner cavity of the two core mold bodies 1.

[0027] In the above structure, the use of detachable support legs 3 not only enhances the stability of the support, but also allows the support legs 3 of different heights to be replaced conveniently and quickly to adjust the construction distance between the core mold body 1 and the bottom plate 321 steel bars of the hollow floor. The use of multiple core mold bodies 1 connected together improves the stability of the structure.

[0028] like Figure 1 As shown, in one embodiment, the clamping portion 31 of the hollow floor core mold with supporting feet includes two relatively inclined clamping plates 311, and a clamping slot 312 is provided on the clamping plate 311.

[0034] Specifically, a plurality of core mold bodies 1 may be provided, and adjacent core mold bodies 1 are connected by two support bodies 2, and the cavity of the support body 2 is communicated with the inner cavity of two adjacent core mold bodies 1. The support body 2 and the core mold body 1 are integrally formed.

[0035] The one-piece structure is convenient for use in large-sized hollow floor slabs, which not only improves the structural strength of the core mold, but also reduces the number of core molds used, reduces the construction intensity, and effectively improves the construction efficiency. The provision of the two support bodies 2 is conducive to enhancing the stability of the connection between the two core mold bodies 1.

[0036] like Figure 2 As shown, in one embodiment, a connector 4 is provided between the two opposite sides of the core mold bodies 1 of the hollow floor core mold with supporting feet and the two opposite sides of the supporting bodies 2, and a through hole 41 is provided on the connector 4. When pouring concrete, the through hole 41 can discharge the gas between the bottom plate 321 steel bars and the multiple core mold bodies 1.

[0037] The connection body 4 improves the structural strength between the two core mold bodies 1. The through hole 41 is provided to facilitate the discharge of gas in the inner cavity and the cavity.
