Description

Technical Field

[0001] This utility model relates to the field of interlocking refractory bricks, and more particularly to an interlocking refractory brick with built-in fixing components. Background Technology

[0002] Refractory bricks are a key basic material for the lining of various high-temperature kilns and thermal equipment. The stability of their masonry structure is directly related to the safe operation and service life of the entire equipment.

[0003] In conventional masonry techniques, refractory bricks are typically laid by stacking them layer by layer. The connection between bricks relies mainly on their own weight and the adhesion of refractory mortar. While this method can maintain a basic structural form at room temperature, its reliability is very limited; essentially, it is still a simple contact between independent individuals.

[0004] However, refractory bricks operate in extremely harsh environments, requiring them to withstand prolonged exposure to high temperatures and drastic temperature changes. Under the repeated effects of thermal expansion and contraction, the bricks generate strong lateral and longitudinal expansion stresses. Because traditional masonry structures lack effective mechanical locking mechanisms to constrain and resist these stresses, bricks are prone to mutual compression, misalignment, and slippage, leading to widened joints, loosening of the masonry, and ultimately compromising the overall sealing and structural integrity of the furnace lining, potentially even causing collapse accidents. Therefore, how to enhance the connection strength of refractory brick masonry to form a stable integral structure is a pressing technical problem in the field of refractory materials. This invention proposes a spliced ​​refractory brick with built-in fixing components to address the shortcomings of existing technologies. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a spliced ​​refractory brick with built-in fixing components, which aims to improve the problem of low connection reliability in some spliced ​​refractory bricks in the prior art due to reliance on simple stacking or mortar bonding.

[0006] This utility model provides a splicing refractory brick with built-in fixing components, including: brick blocks; and fixing components.

[0007] The fixing component is embedded and fixed in the center area of ​​the top surface of the brick. The fixing component and the brick are a single integral structure that is seamlessly connected through an integral molding process to ensure the stability of the connection. The top surface of the fixing component extends upward to form a cylindrical protrusion for longitudinal splicing and locking. At the same time, the bottom surface of the brick is provided with a corresponding circular groove for engagement.

[0008] Furthermore, the bricks, fixing components, cylindrical protrusions and circular grooves are combined in the following way: the circular grooves on the bottom surface of the upper bricks and the cylindrical protrusions on the top surface of the lower bricks are matched in shape and size, so that they can be aligned and engaged during construction to form a stable vertical mechanical lock, thereby effectively preventing longitudinal separation or misalignment between the bricks.

[0009] Preferably, in order to achieve lateral splicing and locking between bricks, a square protrusion is fixedly connected to one of the long side walls of the brick, and a square groove that matches the square protrusion is opened on the other opposite long side wall of the brick. The structure allows adjacent bricks to form a tight interlock in the horizontal direction through the interlocking of the protrusion and groove, thereby forming a stable planar structural layer.

[0010] Preferably, as a specific implementation, the number of cylindrical protrusions extending upward from the top surface of the fixing component is two, and these two cylindrical protrusions are symmetrically arranged side by side along the length direction of the brick. This multi-point connection design greatly enhances the connection stability and torsional resistance between the upper and lower bricks compared to single-point connection.

[0011] Preferably, the number of circular grooves on the bottom surface of the brick is the same as the number of cylindrical protrusions, and their positions precisely correspond to the bottom of the cylindrical protrusion on the top of another brick. This precise correspondence ensures accurate and rapid vertical alignment and engagement when stacked, guaranteeing the efficiency of masonry and the regularity of the structure.

[0012] Preferably, the length extension direction of the square protrusion is set to be perpendicular to the axial direction of the cylindrical protrusion. This three-dimensional orthogonal locking structure layout enables the masonry to be effectively constrained in both the horizontal and vertical dimensions, forming a comprehensive spatial lock that can more effectively resist stress from different directions.

[0013] Preferably, the square protrusion is a strip-shaped protrusion structure extending along the entire length of one of the long sidewalls of the brick, and the square groove is a strip-shaped groove structure extending along the entire length of the other opposite long sidewall of the brick. This linear contact design extending along the entire length maximizes the area of ​​lateral engagement, making the locking force in the horizontal direction more uniform and stronger.

[0014] Preferably, as a design to improve installation convenience, the top of the cylindrical protrusion is provided with a chamfer or arc transition. The smooth transition structure can play an automatic alignment and guiding role when the bricks are stacked and spliced, so that the circular groove can be more easily fitted into the cylindrical protrusion, significantly reducing the construction difficulty.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model achieves a double locking between bricks in both the horizontal and vertical directions by setting square protrusions and square grooves on the side walls of the bricks, and setting cylindrical protrusions and circular grooves on the top and bottom of the bricks. This solves the problem that existing refractory bricks rely on simple stacking or mortar connection, resulting in a loose structure and poor connection reliability. It achieves the technical effect of constructing a stable and tightly connected whole masonry by dispersing bricks.

[0017] 2. This utility model solves the problem of brick displacement, loosening or even falling off caused by the lateral or longitudinal thrust generated by thermal expansion in refractory brick masonry under high-temperature working environment through a mechanical locking structure formed by lateral convex and concave engagement and longitudinal convex and concave insertion. It achieves the technical effect of significantly improving the thermal shock resistance and structural durability of masonry and extending the service life of equipment.

[0018] 3. This utility model solves the problems of difficult alignment, reliance on manual experience, low construction efficiency, and difficulty in ensuring accuracy in traditional refractory brick masonry by pre-setting square and circular protrusions and grooves on the bricks as self-positioning structures, especially the guide design on the top of the cylindrical protrusion. It achieves the technical effect of simplifying the installation process, reducing construction difficulty, and ensuring accurate and reliable splicing. Attached Figure Description

[0026] 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.

[0027] Example:

[0028] Reference Figures 1 to 3 This utility model provides a spliced ​​refractory brick with built-in fixing components, which aims to solve the problem of insufficient stability of masonry structures caused by the displacement of existing refractory bricks due to thermal expansion.

[0029] like Figure 1 , Figure 2 and Figure 3 As shown, the main structure of the interlocking refractory brick with built-in fixing components is brick 1. Brick 1 integrates mounting components 2 for longitudinal splicing and a structure for lateral splicing, which will be described later. Specifically, mounting components 2 are fixedly connected to the center area of ​​the top surface of brick 1. Mounting components 2 are the core component for longitudinal locking between upper and lower bricks 1. They are a seamless, integral structure formed with brick 1 through a one-piece molding process, enhancing the stability of mounting components 2 within brick 1. A cylindrical protrusion 21 extends upwards from the top surface of mounting components 2. It is an upward splicing connection structure with a chamfer or rounded transition at the top. The chamfer or rounded transition facilitates guidance when splicing with other bricks 1, thereby simplifying the installation process. As a structure that cooperates with the cylindrical protrusion 21, the bottom surface of the brick 1 is provided with a circular groove 22. The inner diameter and depth of the circular groove 22 are precisely matched with the outer diameter and height of the cylindrical protrusion 21, thereby ensuring that the circular groove 22 of the upper brick 1 can achieve tight upper and lower alignment and meshing when it is installed with the cylindrical protrusion 21 of the lower brick 1, thus preventing longitudinal misalignment or separation between the bricks 1.

[0030] Reference Figure 1 and Figure 3 A square protrusion 3 is fixedly connected to one of the long side walls of brick 1; as a matching structure, a square groove 4 is provided on the other opposite long side wall of brick 1. The shape and size of the square groove 4 are precisely matched with the square protrusion 3. The square protrusion 3 is a strip-shaped protrusion structure extending along the entire length of one of the long side walls, and the square groove 4 is also a strip-shaped groove structure extending along the entire length of the other opposite long side wall. The length extension direction of the square protrusion 3 is set to be perpendicular to the axis direction of the cylindrical protrusion 21. When laying bricks horizontally, two adjacent bricks 1 are placed side by side. The square protrusion 3 of one brick 1 can be completely embedded in the square groove 4 of the other brick 1, forming a tight interlocking connection. This structure ensures that the bricks 1 cannot easily move relative to each other in the horizontal direction, thereby effectively resisting lateral thrust and ensuring the structural integrity of the same layer of masonry.

[0031] Reference Figure 2The mounting component 2 has two cylindrical protrusions 21 extending upward from its top surface, and these two cylindrical protrusions 21 are symmetrically arranged side by side along the length of the brick 1. Correspondingly, the brick 1 also has two circular grooves 22 on its bottom surface, and their positions are precisely below the top cylindrical protrusion 21 of the other brick 1. This ensures that when the bricks are stacked and built, the two cylindrical protrusions 21 can simultaneously align and engage with the two circular grooves 22 to form a multi-point locking structure, thereby greatly improving the vertical connection strength and overall stability of the masonry.

[0032] The implementation principle of this application embodiment is as follows: When laying bricks, the bricks 1 of the same layer are first horizontally spliced. By inserting the square protrusion 3 of one brick 1 into the square groove 4 of the adjacent brick 1, the horizontal interlocking and locking is achieved. The structure connects all bricks 1 in the same horizontal layer into a whole. When the horizontal thrust is generated due to thermal expansion, the interlocking structure can effectively prevent the relative horizontal slippage between bricks 1, thereby ensuring the flatness and integrity of the masonry layer.

[0033] After the lower layer is laid, the upper layer bricks 1 are vertically spliced. During installation, a staggered connection method is used. The circular groove 22 on the bottom surface of the upper layer brick 1 is aligned with the cylindrical protrusion 21 on the top of the lower layer brick 1 and stacked. The chamfer or arc transition on the top of the cylindrical protrusion 21 plays a guiding role, so that the upper layer brick 1 can be smoothly installed on the lower layer brick 1 and the cylindrical protrusion 21 and the circular groove 22 are vertically engaged and locked. The structure effectively prevents the bricks 1 from separating or lifting in the vertical direction.

[0034] By engaging the transverse square protrusion 3 with the square groove 4 and engaging the longitudinal cylindrical protrusion 21 with the circular groove 22, this utility model effectively mechanically locks each brick 1 in three-dimensional space, combining the dispersed bricks 1 into a structurally stable and tightly connected integral masonry. When the integral masonry is subjected to high temperature and thermal expansion, this three-dimensional locking structure can disperse and constrain the expansion stress internally, effectively resisting transverse or longitudinal thrust, and ultimately solving the problem of displacement and loosening of refractory bricks caused by thermal expansion, significantly improving the structural stability and service life of the masonry.
