Description

Technical Field

[0001] This utility model belongs to the field of composite brick technology, specifically relating to a fiber-containing refractory composite brick. Background Technology

[0002] In our lives, the construction of buildings around us requires the use of various materials, among which bricks are indispensable. With the development of technology, there are more and more types of bricks. In order to achieve fire resistance and heat insulation, composite bricks are needed.

[0003] In existing refractory composite bricks, the internal refractory fibers significantly reduce heat loss to the outside of the brick. The low thermal conductivity of the refractory fibers effectively blocks heat transfer. However, due to the significant difference in material properties between the fibers and the refractory matrix, their coefficients of thermal expansion are not synchronized under high-temperature environments. This can easily lead to stress concentration at the interface. Over time, these stress concentration points can trigger the formation and propagation of cracks, eventually causing internal fracture of the brick. On the other hand, during the production process of refractory composite bricks, pores may form inside the brick. Large or concentrated pores can reduce the overall strength of the brick. During transportation and collisions, the area around the pores becomes a stress concentration zone. When the stress exceeds the brick's bearing capacity, cracks will form and extend inward, causing fracture and affecting the use of the refractory composite brick. Utility Model Content

[0004] The purpose of this invention is to provide a fiber-containing refractory composite brick to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fiber-containing refractory composite brick, comprising:

[0006] A composite brick, wherein a positioning block is connected to one end of the composite brick, and a positioning groove is provided in the other end, and the positioning block is inserted into the positioning groove;

[0007] The inner brick core is located inside the composite brick and a reinforcing layer is provided between the inner brick core and the composite brick. The inner brick core has a skeleton and is filled with volcanic rock fiber. The skeleton includes a connecting horizontal plate. The connecting horizontal plate is located inside the inner brick core and several support plates are connected to the surface of the connecting horizontal plate. The other end of the support plate is connected to the inner brick core.

[0008] Preferably, a flame-retardant plate is provided between the composite brick and the reinforcing layer.

[0009] Preferably, the support plate and the connecting cross plate are arranged in a triangle.

[0010] Preferably, the reinforcing layer includes fiberglass horizontal plates and fiberglass vertical plates, and each fiberglass horizontal plate and fiberglass vertical plate is provided with several groups.

[0011] Preferably, several fiberglass horizontal and vertical plates are interlaced to form a reinforcing grid and connected between the inner brick core and the flame-retardant board.

[0012] Preferably, the intersection of the fiberglass horizontal plate and the fiberglass vertical plate is connected by a fixing block.

[0013] Preferably, the composite brick has several protrusions at its bottom.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] (1) The skeleton set by the inner brick core is composed of connecting horizontal plates and several support plates. The support plates and connecting horizontal plates are set in a triangle. The triangular structure has good stability and load-bearing capacity, which can effectively enhance the structural strength of the inner brick core, so that it can maintain shape stability when subjected to external force or high temperature deformation, and reduce the risk of overall deformation and cracking of the brick. The reinforcing layer contains multiple sets of glass fiber horizontal plates and glass fiber vertical plates. The crisscrossing glass fiber plates further strengthen the structure of the composite brick. The glass fiber itself has high strength and can effectively disperse stress, improve the impact and compression resistance of the composite brick. The longitudinal carbon fiber bundles and transverse carbon fiber bundles intersect to form a reinforcing grid, which not only increases the overall strength of the composite brick, but also provides reinforcement in different directions, so that the composite brick can better withstand external force in all directions and reduce crack generation.

[0016] (2) Volcanic rock fiber is filled in the skeleton. Volcanic rock fiber has good high temperature resistance and low thermal conductivity, which can effectively block heat transfer and reduce heat loss to the outside of the composite brick, thus achieving good heat insulation effect. In high temperature environment, the difference in thermal expansion coefficient between volcanic rock fiber and refractory matrix is ​​relatively small. Compared with other fibers, it can reduce stress concentration at the interface, reduce the possibility of crack generation and propagation caused by thermal expansion and contraction, improve the thermal shock resistance of composite brick, and extend its service life.

[0017] (3) The flame-retardant board installed between the composite brick and the reinforcing layer further enhances the fire resistance and flame retardant performance of the composite brick. The flame-retardant board can effectively prevent the spread of flames and delay the damage of the fire to the internal structure of the composite brick when a fire occurs.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] This utility model provides, for example Figure 1-4 The fiber-containing refractory composite brick shown includes:

[0025] Composite brick 1, one end of which is connected to a positioning block 2, and the other end is provided with a positioning groove 3, wherein the positioning block 2 is inserted into the positioning groove 3;

[0026] The inner brick core 4 is disposed inside the composite brick 1 and a reinforcing layer 5 is provided between the inner brick core 4 and the composite brick 1. The inner brick core 4 is provided with a skeleton and the skeleton is filled with volcanic rock fiber 6. The skeleton includes a connecting horizontal plate 7. The connecting horizontal plate 7 is disposed inside the inner brick core 4 and several support plates 8 are connected to the surface of the connecting horizontal plate 7, and the other end of the support plate 8 is connected to the inner brick core 4.

[0027] A flame-retardant plate 13 is provided between the composite brick 1 and the reinforcing layer 5. The flame-retardant plate 13 can prevent the flame from directly contacting other parts of the composite brick 1, thereby effectively protecting the internal structure of the composite brick 1 and reducing the degree of damage caused by fire.

[0028] The support plate 8 and the connecting horizontal plate 7 are arranged in a triangle.

[0029] The reinforcing layer 5 includes a glass fiber horizontal plate 9 and a glass fiber vertical plate 10, and each of the glass fiber horizontal plate 9 and the glass fiber vertical plate 10 is provided with several groups.

[0030] Several fiberglass horizontal plates 9 and fiberglass vertical plates 10 are interlaced to form a reinforcing grid and connected between the inner brick core 4 and the flame-retardant board 13.

[0031] The intersection of the fiberglass horizontal plate 9 and the fiberglass vertical plate 10 is connected by a fixing block 11. The fixing block 11 reinforces the fiberglass horizontal plate 9 and the fiberglass vertical plate 10 to form a more stable overall reinforced grid.

[0032] The bottom of the composite brick 1 is provided with several protrusions 12. The presence of the protrusions 12 increases the contact area between the bottom of the composite brick 1 and the adhesive material. A larger contact area means more bonding sites, which allows the adhesive material to better wrap the protrusions 12 and form a stronger bond.

[0033] When installing the fiber-containing refractory composite brick, the positioning block 2 of one composite brick 1 is aligned with the positioning groove 3 of another composite brick 1 and inserted. This design ensures that each brick is accurately positioned during the laying process, guaranteeing the flatness and verticality of the composite brick 1. Furthermore, the cooperation between the positioning block 2 and the positioning groove 3 enhances the tightness of the connection between bricks and improves the stability of the overall structure. When the protrusion 12 at the bottom of the composite brick 1 is in close contact with the supporting surface after installation, the presence of the protrusion 12 increases the contact area between the bottom of the composite brick 1 and the adhesive material. A larger contact area means more bonding points, allowing the adhesive material to better wrap the protrusion 12 and form a stronger bond.

[0034] Inside the composite brick 1, the skeleton of the inner brick core 4 plays a key supporting role. The connecting horizontal plate 7 and the support plate 8 form a stable triangular structure. One end of the support plate 8 is connected to the horizontal plate 7, and the other end is connected to the inner brick core 4, which evenly distributes the pressure and external force on the inner brick core 4. When the composite brick 1 is subjected to external pressure or impact, the triangular structure can effectively transmit and disperse the force, preventing the inner brick core 4 from being deformed or damaged due to excessive local stress. The glass fiber horizontal plate 9 and glass fiber vertical plate 10 of the reinforcing layer 5 are interwoven to form a reinforcing grid, which enhances the overall structural strength of the composite brick 1. When the composite brick 1 is under stress, the reinforcing layer 5 can share some of the stress, further improving the composite brick 1's resistance to damage. The reinforcing grid formed by the interlacing of longitudinal carbon fiber bundles and transverse carbon fiber bundles strengthens the structure of the composite brick 1 from different directions. When the composite brick 1 is subjected to external forces from various directions, the reinforcing layer 5 can disperse the stress, prevent the generation and propagation of cracks, and ensure the structural integrity of the composite brick 1.

[0035] The volcanic rock fiber 6 filled in the skeleton makes it difficult for heat to be conducted within the composite brick 1 due to its low thermal conductivity. When one side of the composite brick 1 is in a high-temperature environment, the volcanic rock fiber 6 can effectively block the heat from being transferred to the other side, reducing heat loss. The numerous tiny pores inside the volcanic rock fiber 6, with air in these pores being poor conductors of heat, further hinder heat conduction, thus achieving a good thermal insulation effect. In addition, the flame-retardant board 13 is located between the composite brick 1 and the reinforcing layer 5. When a fire occurs, the flame-retardant components in the flame-retardant board 13 will undergo a chemical reaction at high temperatures to form a heat insulation layer, thereby preventing the spread of flames and protecting the internal structure of the composite brick 1 from direct flame erosion.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
