Description

Technical Field

[0001] This utility model relates to a two-way densely ribbed precast slab for gypsum molds, and mainly relates to the field of precast slabs. Background Technology

[0002] The new type of composite ribbed floor slab is formed by pre-embedding composite molds according to certain rules, followed by the pouring of concrete. Currently, in order to increase the thickness of the floor slab and reduce its self-weight, cavities are set inside the floor slab. However, the methods for processing these cavity structures vary from company to company. The commonly used method is to directly use pre-formed molds, but pre-formed molds occupy a large space and are inconvenient to transport. Utility Model Content

[0003] To address the shortcomings of the existing technology, this utility model proposes a two-way densely ribbed precast slab for gypsum molds. The structure, which is thicker in the middle and thinner at both ends, can reduce the overall thickness of the precast slab while increasing its overall load-bearing capacity. The temporary assembly structure makes it more convenient for transportation.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows:

[0005] Includes lightweight infill, steel reinforcement cage, and concrete;

[0006] The lightweight filler is evenly distributed, and the steel reinforcement cage is arranged around the lightweight filler. The lightweight filler and the steel reinforcement cage are filled with concrete.

[0007] The lightweight filler is thicker in the middle and thinner at both ends.

[0008] The technical principle and beneficial effects of this utility model are as follows:

[0009] The use of a structure that is thicker in the middle and thinner at both ends can reduce the overall thickness of the precast slab while increasing the overall load-bearing capacity. Furthermore, the thicker middle section can reduce the possibility of lightweight fillers floating during concrete pouring.

[0010] Preferably, the lightweight filler comprises a cylindrical structure in the middle and caps at both ends. It can be temporarily assembled before casting.

[0011] Preferably, the cylindrical structure includes trapezoidal side plates, the side edges of which are spliced ​​to enclose the cylindrical structure. That is, four trapezoidal side plates can be combined to form a tiered structure, and two tiered structures can be joined at their bottoms to form a cylindrical structure with a thicker middle section. During transportation, only the trapezoidal side plates and the cover plate need to be transported, which is more convenient and improves space utilization.

[0012] Preferably, the cross-section of the lightweight filler is rectangular.

[0013] Preferably, the lightweight filler is made of gypsum. This makes it even lighter.

[0014] Preferably, the cover plate and the cylindrical structure are bonded together with plaster. This results in better adhesion and a more airtight seal.

[0015] Preferably, the inner wall of the cylindrical structure is provided with a plurality of supporting ribs along the axial direction. This can improve the strength of the cylindrical structure.

[0016] Preferably, the thickest part of the cylindrical structure extends outward into the reinforcing steel frame. This can hold the cylindrical structure in place, preventing it from floating during concrete pouring. Attached Figure Description

[0022] Example

[0023] like Figure 1 As shown, this utility model embodiment includes a lightweight filler, a steel reinforcement cage, and concrete; the lightweight filler is evenly distributed, the steel reinforcement cage is arranged around the lightweight filler, and the lightweight filler and the steel reinforcement cage are filled with concrete; the lightweight filler is thicker in the middle and thinner at both ends.

[0024] The technical principle and beneficial effects of this utility model are as follows:

[0025] The use of a structure that is thicker in the middle and thinner at both ends can reduce the overall thickness of the precast slab while increasing the overall load-bearing capacity. Furthermore, the thicker middle section can reduce the possibility of lightweight fillers floating during concrete pouring.

[0026] Preferably, the lightweight filler includes a cylindrical structure in the middle and cover plates 3 at both ends. It can be temporarily assembled before casting.

[0027] The cylindrical structure includes trapezoidal side plates 2, which are spliced ​​along their sides to enclose the cylindrical structure. That is, four trapezoidal side plates 2 can be combined to form a tiered structure, and two tiered structures can be joined at their bottoms to form a cylindrical structure with a thicker middle section. During transport, only the trapezoidal side plates 2 and the cover plate 3 need to be transported, making transport more convenient and improving space utilization.

[0028] The cross-section of the lightweight filler is rectangular.

[0029] The lightweight filler is made of gypsum, making it even lighter.

[0030] The cover plate 3 is bonded to the cylindrical structure with plaster. This results in better adhesion and a more airtight seal.
