Description

Technical Field

[0001] This utility model relates to the field of building wall materials technology, and in particular to a foamed concrete partition wall panel. Background Technology

[0002] Foamed concrete partition boards, as a new type of lightweight wall material, have lower density and better thermal insulation performance compared to traditional wall materials, and have been widely used in various construction projects such as residential buildings, commercial complexes, and industrial plants.

[0003] However, due to the large number of air bubbles inside foamed concrete, the material itself is brittle. When the wall panel is subjected to bending loads in the length or width direction, such as localized stress during handling or excessive spacing between support points during installation, stress tends to concentrate around the air bubbles, causing the material to crack from the internal air bubbles and expand rapidly. This can easily lead to fractures and breaks in the central area, seriously affecting the structural safety and service life of the wall.

[0004] Based on the above situation, it is necessary to design a foamed concrete partition wall panel to solve the above problems. Utility Model Content

[0005] This invention provides a foamed concrete partition wall panel to solve the problem that existing walls are prone to breakage due to bending loads.

[0006] The technical problem solved by this utility model is achieved by the following technical solution:

[0007] A foamed concrete partition wall panel includes a wall panel body, the wall panel body including a core layer located in the middle and a covering layer located on both sides of the core layer, and further including a reinforcing unit disposed in the core layer. The reinforcing unit includes multiple sets of first reinforcing ribs and multiple sets of second reinforcing ribs. The first reinforcing ribs and the second reinforcing ribs are respectively arranged along the length and width directions of the wall panel body, and are used to cooperate with the wall panel body to bear force and jointly resist the bending of the wall panel body in the length and width directions.

[0008] Preferably, both the first reinforcing rib and the second reinforcing rib are provided with a mesh fabric layer, and the mesh fabric layer is spirally wrapped around the first reinforcing rib and the second reinforcing rib along their length extension direction.

[0009] Preferably, the two ends of the mesh fabric extend toward the ends of the first reinforcing rib and the second reinforcing rib and are folded over to wrap around their end faces, forming a closed wrapping structure.

[0010] Preferably, the core layer is provided with a connecting fastener, which is simultaneously fitted at the intersection of the first reinforcing rib and the second reinforcing rib.

[0011] Preferably, the surfaces of the first reinforcing rib and the second reinforcing rib are provided with a spiral-shaped rough structure.

[0012] Preferably, the outer wall of the mesh fabric layer is coated with modified cement slurry.

[0013] The beneficial effects of this utility model are as follows: by forming a three-dimensional reinforcement system through the first and second reinforcing ribs, the bending resistance of the wall panel is improved. When the wall panel is subjected to bending force in the length or width direction, the reinforcing unit can directly bear part of the tensile force, reducing the stress burden on the core layer. When the wall panel body is subjected to bending load, the first and second reinforcing ribs work together to bear the tensile force. Through the stress dispersion effect of the mesh layer and the tensile support effect of the first and second reinforcing ribs, the stress generated by the external force is evenly transmitted to the entire wall panel body, avoiding the risk of stress concentration in local areas leading to the fracture of the wall panel body.

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0020] Reference Figures 1-3As shown, a foamed concrete partition wall panel includes a wall panel body 1. The wall panel body 1 includes a core layer 11 located in the middle and cover layers 12 located on both sides of the core layer 11. The core layer 11 can be a cement-fiber polystyrene particle foam layer currently available on the market, serving as the core filling layer of the wall and undertaking the main functions of lightweight, heat insulation, and support. The cover layers 12 can be a board layer containing materials such as calcium silicate board, which plays a protective, surface-strengthening, and shape-fixing role. However, currently, using a cement-fiber polystyrene particle foam layer as the core layer 11 results in a large amount of foam mixed in the middle, making it prone to breakage under stress. Therefore, the improvement of this solution is that a reinforcing unit is provided inside the core layer 11. The reinforcing unit includes multiple sets of first reinforcing ribs 2 and multiple sets of second reinforcing ribs 3. The first reinforcing ribs 2 and second reinforcing ribs 3 are respectively arranged along the length and width directions of the wall panel body 1, and are used to reinforce the core layer 1. The wall panel body 1 works together to resist bending in both the length and width directions. When the wall panel body 1 is subjected to external force in the length direction, the first reinforcing rib 2 can bear part of the tensile force, reducing stress concentration in the core layer 11 in that direction, thereby resisting bending in the length direction. When the wall panel body 1 is subjected to external force in the width direction, the second reinforcing rib 3 can also play a similar role, bearing the corresponding tensile force to resist bending in the width direction. Through the cooperation of the first reinforcing rib 2 and the second reinforcing rib 3 in the two directions, the defect of insufficient flexural strength caused by excessive foam in the core layer 11 can be effectively compensated, significantly improving the overall flexural strength of the wall panel body 1, reducing the risk of breakage under stress, and the first reinforcing rib 2 and the second reinforcing rib 3 can be made of materials with high tensile strength, such as glass fiber, without excessively increasing the weight of the wall body.

[0021] Reference Figure 3 As shown, both the first reinforcing rib 2 and the second reinforcing rib 3 are provided with a mesh fabric layer 4, and the mesh fabric layer 4 is spirally wrapped along the length extension direction of the first reinforcing rib 2 and the second reinforcing rib 3. When the first reinforcing rib 2 and the second reinforcing rib 3 bear tensile force, the spiral mesh fabric layer 4 can diffuse the stress in all directions along the winding direction. For example, when a certain point is subjected to force, the stress will be transmitted to the adjacent mesh fabric area through the spiral pattern, and then dispersed by the mesh fabric layer 4 to the surrounding core layer 11, avoiding stress concentration at the contact point between the rib and the core layer 11, and reducing the risk of the core layer 11 being damaged due to excessive local stress.

[0022] Furthermore, the two ends of the mesh fabric layer 4 extend towards the ends of the first reinforcing rib 2 and the second reinforcing rib 3 and are folded over to wrap around their end faces, forming a closed wrapping structure. Specifically, during installation, after the mesh fabric layer 4 extends to the edge of the ends of the first reinforcing rib 2 and the second reinforcing rib 3, it is folded inward along the outer periphery of the end face of the rib, so that the end of the mesh fabric layer 4 covers the entire area of ​​the end face of the rib, and the folded part is fitted and fixed with the mesh fabric layer 4 on the side of the rib, strengthening its integrity with the mesh fabric layer 4, ensuring the effective transmission of tension from the rib to the mesh fabric layer 4, preventing the material in the core layer 11 from seeping into the gap between the end of the rib and the mesh fabric layer 4 during molding or stress, and avoiding stress concentration caused by local material accumulation.

[0023] Reference Figure 3 As shown, furthermore, an improved cement slurry is coated on the outer wall of the mesh layer 4. The improved cement slurry can serve as a transitional bonding medium between the mesh layer 4 and the core layer 11, enhancing the bonding force between the mesh layer 4 and the core layer 11. After curing, the improved cement slurry forms a hard outer shell, tightly wrapping the spirally wound mesh layer 4 with the first reinforcing rib 2 and the second reinforcing rib 3 inside into a whole, thereby constraining the deformation of the mesh layer 4 under stress and preventing performance degradation due to fiber loosening or local tearing. The surfaces of the first reinforcing rib 2 and the second reinforcing rib 3 are provided with a spiral-patterned rough structure, which can increase the actual contact area between the first reinforcing rib 2 and the second reinforcing rib 3 and the mesh layer 4, making the bonding force distribution more uniform and avoiding relative sliding with the mesh layer 4 under stress.

[0024] Reference Figure 2 As shown, further, a connecting fastener 5 is provided in the core layer 11. The connecting fastener 5 is simultaneously sleeved at the intersection of the first reinforcing rib 2 and the second reinforcing rib 3 to connect the first reinforcing rib 2 and the second reinforcing rib 3. The connecting fastener 5 can be tightly connected to the first reinforcing rib 2 and the second reinforcing rib 3 by welding or other connection methods to form a rigid node. When the wall panel body 1 is subjected to bending load, the connecting fastener 5 at the intersection can constrain the relative displacement of the intersecting first reinforcing rib 2 and the second reinforcing rib 3.

[0025] During production, the mesh fabric layer 4 is first wrapped around the first reinforcing rib 2 and the second reinforcing rib 3 respectively. Then, the modified cement slurry is applied to the first reinforcing rib 2 and the second reinforcing rib 3. The first reinforcing rib 2 and the second reinforcing rib 3 are then connected to the connecting fastener 5. A positioning frame is preset in the wall panel mold, and the reinforcing units coated with modified cement slurry 6 are fixed according to the design spacing and position. Then, foamed concrete slurry is poured into the mold. The slurry will wrap around the reinforcing units. The modified cement slurry 6 on the outside of the mesh fabric layer 4 will come into contact with the foamed concrete slurry. As the cement hydration process occurs, the latex powder in the modified cement slurry 6 forms a film and forms a tight bond with the foamed concrete. At the same time, the mesh structure of the mesh fabric will be embedded in the foamed concrete to form a fixed core layer 11. Then, the covering layer 12 is poured on the outside of the core layer 11.
