Technical Field

[0001] The utility model relates to the technical field of precast wall panels, in particular to a precast wall panel with strong weather resistance and crack prevention. Background Technique

[0002] Precast wall panels are reinforced concrete slab-type components processed and manufactured in precast factories or construction sites for building assembly, simply referred to as wall panels or wallboards. Using precast concrete wall panels to build prefabricated large-panel buildings can improve the degree of factory and mechanized construction, reduce on-site wet operations, save on-site labor, overcome seasonal influences, and shorten the building construction period.

[0003] The Chinese patent discloses a precast wall panel (authorization announcement number CN220725511U). This patented technology improves the fit between the wall panel connector and the wall panel monomer, enhances the sealing effect, avoids the convenient installation of the reinforcing bars of the connecting member, has the effect of improving the on-site assembly efficiency, improves the practicality, improves the durability during the connection of precast wall panels, and makes the connection and sealing more stable.

[0004] In view of the above and existing related technologies, the inventor believes that the following defects often exist: However, in addition to the connection efficiency problem, the existing precast wall panels are also prone to cracking due to external factors. The cracking of precast wall panels will cause the decline of the compressive and sealing performance of the panel body, thus affecting the service life and compressive performance of precast wall panels and reducing the use effect. Content of the Utility Model

[0005] The technical problem to be solved by the utility model is that in the prior art, precast wall panels are prone to cracking due to external reasons. For this reason, we propose a precast wall panel with strong weather resistance and crack prevention.

[0013] Technical effects and advantages of the present utility model:

[0014] In the present utility model, during the use of the precast wall panel body, cracking may occur due to external collisions or long-term use. Cracking will cause a decline in the compressive and sealing performance of the precast wall panel body. Through the arrangement of the strengthening core and the sliding plate, the precast wall panel body can enhance additional bearing capacity and stability during use, which helps to resist external forces such as wind pressure and seismic forces, thereby reducing the cracking risk of the wall panel and extending the service life.

[0020] Now, the present utility model will be further described in detail with reference to the drawings and preferred embodiments. These drawings are all simplified schematic diagrams, only showing the basic structure of the present utility model in a schematic manner, so they only show the components related to the present utility model.

[0021] Refer to Figure 1 and Figure 2As shown in the figure, the present utility model provides a technical solution: a precast wall panel with strong weather resistance and crack prevention, including a precast wall panel main body 1. Reinforcing bars 2 are installed inside the precast wall panel main body 1. The number of the reinforcing bars 2 is several and they are evenly distributed inside the precast wall panel main body 1. A reinforcing core 3 is installed inside the precast wall panel main body 1. A plurality of slots 4 are opened inside the precast wall panel main body 1. Sliding plates 5 are fixed at the front end and the rear end of the reinforcing core 3. The inside of the slots 4 is slidably connected with the sliding plates 5. During the use of the precast wall panel main body 1, it may crack due to external collisions or long-term use. Cracking will cause the compressive and sealing performance of the precast wall panel main body 1 to decline. Through the setting of the reinforcing core 3 and the sliding plates 5, the precast wall panel main body 1 can enhance the additional bearing capacity and stability during use, which helps to resist external forces such as wind pressure and seismic force, thereby reducing the cracking risk of the wall panel and improving the service life.

[0022] Referring to Figure 1 As shown in the figure, in this implementation scheme: the main material of the precast wall panel main body 1 is expanded perlite particle concrete. Through the setting of this material, the main body of the precast wall panel main body 1 can have better compressive and environmental protection performance, and the overall production price is relatively low, which can significantly improve the use experience of the precast wall panel main body 1.

[0023] Referring to Figure 3 And Figure 4 As shown in the figure, in this implementation scheme: a silicate cement layer 6 is installed on the surface of the precast wall panel main body 1. Through the setting of the silicate cement layer 6, because it has a small drying shrinkage value, it helps to maintain the stability and integrity of the structure. If the drying shrinkage rate of the material is too large, it may cause the components to crack, deform or lose strength, thus affecting the safety and durability of the entire structure, and reducing the service life of the precast wall panel main body 1.

[0024] Referring to Figure 4 As shown in the figure, in this implementation scheme: a heat-resistant insulation layer 7 is installed inside the precast wall panel main body 1. Through the setting of the heat-resistant insulation layer 7, the precast wall panel main body 1 can effectively isolate the external temperature during use, thereby ensuring the constancy of the internal temperature and improving the use experience of the user.

[0025] Referring to Figure 4 As shown in the figure, in this implementation scheme: an anti-corrosion layer 8 is installed inside the precast wall panel main body 1. Through the setting of the anti-corrosion layer 8, the precast wall panel main body 1 can have good antioxidant and anti-corrosion functions. These characteristics can help the precast wall panel main body 1 better resist bad weather and ensure the long-term stability and aesthetic effect of the precast wall panel main body 1.

[0026] Referring to Figure 4As shown, in this implementation: A polymer cement mortar waterproof layer 9 is installed inside the precast wall panel main body 1. Through the setting of the polymer cement mortar waterproof layer 9, the precast wall panel main body 1 can effectively isolate rainwater or other water sources outside, preventing water from entering the inside of the precast wall panel main body 1 and causing corrosion and cracking of the internal structure of the precast wall panel main body 1, further improving the service performance of the precast wall panel main body 1.

[0027] Refer to Figure 4 As shown, in this implementation: A sound insulation layer 10 is installed inside the precast wall panel main body 1. Through the setting of the sound insulation layer 10, when the precast wall panel main body 1 is in use, it can effectively isolate external noise, ensuring the quietness of the internal environment of the precast wall panel main body 1 and further improving the user experience.

[0028] Working principle: During the use of the precast wall panel main body 1, it may crack due to external collisions or long-term use. Cracking will cause a decline in the compressive and sealing performance of the precast wall panel main body 1. Through the setting of the strengthening core 3 and the sliding plate 5, the precast wall panel main body 1 can enhance additional bearing capacity and stability during use, helping to resist external forces such as wind pressure and seismic forces, thereby reducing the cracking risk of the wall panel and extending the service life. Through the setting of this material, the main body of the precast wall panel main body 1 can have better compressive and environmental protection performance, and the overall production cost is relatively low, which can significantly improve the user experience of the precast wall panel main body 1. Through the setting of the portland cement layer 6, because it has a small drying shrinkage value, it helps to maintain the stability and integrity of the structure. If the drying shrinkage rate of the material is too large, it may cause the components to crack, deform or lose strength, thus affecting the safety and durability of the entire structure and reducing the service life of the precast wall panel main body 1. Through the setting of the heat-resistant insulation layer 7, the precast wall panel main body 1 can effectively isolate the external temperature during use, thereby ensuring the constancy of the internal temperature and improving the user experience. Through the setting of the anti-corrosion layer 8, the precast wall panel main body 1 can have good antioxidant and anti-corrosion functions. These characteristics can help the precast wall panel main body 1 better resist bad weather, enabling the precast wall panel main body 1 to ensure long-term stability and aesthetic effects. Through the setting of the polymer cement mortar waterproof layer 9, the precast wall panel main body 1 can effectively isolate rainwater or other water sources outside, preventing water from entering the inside of the precast wall panel main body 1 and causing corrosion and cracking of the internal structure of the precast wall panel main body 1, further improving the service performance of the precast wall panel main body 1.
