Description
Technical Field
[0001] The utility model relates to the technical field of concrete, in particular to a graphene modified concrete structure. Background Art
[0002] Concrete generally refers to an engineering composite material in which a binder cements aggregates into a whole. Usually, the term concrete refers to cement concrete, which uses cement as the binder, sand and stone as aggregates; it is mixed with water (which may contain additives and admixtures) in a certain proportion and obtained by stirring, also known as ordinary concrete, and it is widely used in civil engineering.
[0003] However, when the existing concrete structure is in use, the ends of two concrete slabs are usually connected. However, the connection stability at the ends of the concrete slabs is poor, and the concrete slabs are prone to shaking and offset. At the same time, the concrete slabs are exposed to the external environment and are easily cracked under the influence of external forces, which has a certain impact on the service life of the concrete slabs. Therefore, a graphene modified concrete structure is provided. Summary of the Utility Model
[0004] The main purpose of the utility model is to provide a graphene modified concrete structure. By setting a carbon fiber mesh layer, bumps, card slots, wedge slots, grooves, wedge blocks, clamping blocks, flame retardant layer A, flame retardant layer B, wire mesh layer, reinforcing ribs, graphene layer A, graphene layer B, graphene layer C and graphene layer D, the utility model solves the problems that when the existing concrete structure is in use, the splicing stability of the concrete slabs is poor, and at the same time, the crack resistance and flame retardant performance of the concrete slabs are poor, affecting the service life of the concrete slabs.
[0005] The technical solution adopted by the utility model to solve its technical problems is a graphene modified concrete structure, including concrete slab A and concrete slab B. One side of the concrete slab A is provided with a wedge slot for connecting with the concrete slab B. The outside of the concrete slab B of the concrete slab is provided with a wedge block entering the wedge slot. A groove is opened inside the wedge slot, and a bump entering the inside of the groove is arranged on the outside of the wedge block. A card slot is opened on one side of the wedge slot, and a clamping block entering the card slot is arranged on one side of the wedge block. The inside of the concrete slab A is provided with reinforcing ribs for increasing the strength of the concrete slab A. The graphene layer B and graphene layer C for modifying the concrete slab A are symmetrically arranged on the outside of the reinforcing ribs. The wire mesh layer for increasing the strength of the concrete slab A is arranged on the outside of the graphene layer B. The graphene layer A for modifying the concrete slab A is filled on the outside of the wire mesh layer. The carbon fiber mesh layer for increasing the strength of the concrete slab A is arranged on the outside of the graphene layer A. The flame retardant layer A for improving the flame retardant performance of the concrete slab A is arranged on one side of the graphene layer C. The graphene layer D connected with the flame retardant layer B is arranged on the outside of the flame retardant layer A.
[0006] By adopting the above technical solution, when connecting the concrete slab A and the concrete slab B, first place the wedge block outside the concrete slab B into the wedge groove opened on the surface of the concrete slab A. Subsequently, the clamping block outside the wedge block enters the clamping groove in the wedge groove, and at the same time, the convex block on the wedge block enters the groove on the wedge groove, thus facilitating the splicing process of the concrete slab A and the concrete slab B;

The flame retardant layer A outside the graphene layer C is made of fiberglass mesh, and the fiberglass mesh improves the toughness and flexural resistance of the concrete slab A, playing a role in tying, thus effectively controlling the expansion of cracks in the concrete slab A and improving the crack resistance of the concrete slab A. At the same time, the flame retardant layer B outside the graphene layer D is made of polypropylene fiber, and the polypropylene fiber can prevent the phenomenon of concrete shrinkage cracks, thereby improving the crack resistance performance of the concrete slab A. The fiberglass mesh has good flame retardant performance, and at high temperatures, many pores will be formed in the concrete slab A, and the moisture will drain along these pores, avoiding the formation of water vaporization and enhancing the flame retardant performance of the concrete slab A. The internal structure of the concrete slab B is the same as that of the concrete slab A, thereby improving the service life of the concrete slab A and the concrete slab B;
[0008] The evenly distributed graphene layer A, graphene layer B, graphene layer C, and graphene layer D in the concrete slab A enhance the mechanical properties of the concrete, and effectively improve the corrosion resistance of the concrete, extending the service life of the concrete slab A.
[0009] Specifically, the flame retardant layer A is made of fiberglass mesh, and the flame retardant layer B is made of polypropylene fiber.
[0010] By adopting the above technical solution, the flame retardant layer A in the concrete slab A is made of fiberglass mesh, and the fiberglass mesh improves the toughness and flexural resistance of the concrete slab A, playing a role in tying, thus effectively controlling the expansion of cracks in the concrete slab A and improving the crack resistance of the concrete slab A. And the fiberglass mesh has good flame retardant performance. At the same time, the flame retardant layer B in the concrete slab A is made of polypropylene fiber, which can prevent the phenomenon of concrete shrinkage cracks and improve the crack resistance performance of the concrete slab A. And at high temperatures, many pores will be formed in the concrete slab A, and the moisture will drain along these pores, avoiding the formation of water vaporization, thereby improving the crack resistance performance and flame retardant performance of the concrete slab A.
[0011] Specifically, the inner size of the wedge groove matches the outer size of the wedge block.
[0012] By adopting the above technical solution, when the wedge block on the concrete slab B enters the wedge groove opened on the surface of the concrete slab A, the inner side of the wedge groove fits with the outside of the wedge block, facilitating the entry of the wedge block into the inside of the wedge groove.
[0013] Specifically, the size of the inner side of the groove matches the size of the outer side of the convex block.
[0014] By adopting the above technical solution, when the convex block enters the inside of the groove, the size of the inner side of the groove matches the outside of the convex block, facilitating the entry of the convex block into the inside of the groove.
[0015] Specifically, the size of the inner side of the clamping groove matches the size of the outer side of the clamping block.
[0016] By adopting the above technical solution, when the clamping block enters the clamping groove, the size of the inner side of the clamping groove matches the outside of the clamping block, facilitating the entry of the clamping block into the inside of the clamping groove.
