Description

Technical Field

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

[0002] Prefabricated buildings have become the mainstream direction of the construction industry due to their advantages such as high construction efficiency and good environmental protection. As one of the core components of prefabricated buildings, the performance of prefabricated concrete wall panels directly affects the overall quality of the building. For example, patent application number CN202210709943.6 discloses a prefabricated insulated concrete wall panel. It includes several mounting frames and wall panels set inside the mounting frames. The fixing frame includes a central connecting plate and side clamping plates set on both sides of the central connecting plate. The left and right sides of the central connecting plate are provided with rod grooves, and a ball groove is provided at one end of the rod groove. The connecting frame includes a connecting rod, and the two ends of the connecting rod are fixed with connecting tie rods. The wall panel includes a wall panel body, and the two sides of the wall panel body are provided with placement grooves. This invention uses the snap-fit ​​connection between the tie member and the rod groove and ball groove to fix the wall panel between two fixing frames. When the wall panel shrinks during use, the ball groove pulls the ball on the tie member to fix the position of the wall panel. At the same time, the wall panels on both sides of the fixing frame pull the mounting frame to prevent the mounting frame from tilting when the wall panel shrinks, thus ensuring the stability of the wall panel installation.

[0003] When using existing prefabricated concrete wall panels, the panels are often spliced ​​together using simple tongue and groove joints. Gaps are prone to appear at the joints, and long-term use can easily lead to cracking and leakage problems, affecting the stability and durability of the wall and making it impractical. Utility Model Content

[0004] This utility model relates to a prefabricated concrete wall panel, which has a concrete panel body. The concrete panels are assembled and positioned with each other through a connecting part and a groove. The gap between the connecting part and the groove is grouted to ensure the stable connection between the wall panel bodies and avoid cracking and leakage. At the same time, the elastic sealing strip can provide a sealing effect for the connection between adjacent wall panel bodies, which can prevent grout leakage during the grouting process and also prevent rainwater from seeping into the room from the connection. It is stable in use and has extremely high stability and practicality.

[0005] This utility model provides a prefabricated concrete wall panel, specifically comprising: a wall panel body, wherein the wall panel body is a layered composite structure, and the wall panel body includes, from the outside to the inside, a decorative layer, a thermal insulation layer, a sound insulation layer and a concrete slab, adjacent wall panel bodies are spliced ​​and assembled with mortar filling treatment at the splice joints; the wall panel body has a lifting hole inside, the lifting hole penetrating the decorative layer, thermal insulation layer, sound insulation layer and concrete slab, and a decorative plug is fixedly installed on the outside of the lifting hole, and a wear-resistant sleeve is provided on the inner wall of the lifting hole.

[0006] Furthermore, one side of the concrete slab is provided with a protruding connecting part, and the other side of the concrete slab is provided with a groove adapted to the connecting part, and the connecting part of the adjacent wall panel body is inserted into the inside of the groove.

[0007] Furthermore, the connection part is provided with a main grouting channel inside, and a secondary grouting channel is provided on the side of the main grouting channel.

[0008] Furthermore, elastic sealing strips are provided on the sides of the concrete slabs located on both sides of the groove, and the elastic sealing strips are made of aging-resistant rubber material.

[0009] Furthermore, the inner side of the groove on the outside of the connecting part is provided with reinforcing protrusions, and the reinforcing protrusions of the connecting part and the groove are staggered with each other.

[0010] Furthermore, the sound insulation layer is made of sound insulation felt, the thermal insulation layer is made of extruded polystyrene foam board, and the sound insulation layer and the thermal insulation layer are bonded and fixed together with epoxy resin adhesive.

[0011] This utility model provides a prefabricated concrete wall panel, which has the following beneficial effects:

[0012] 1. Reliable connection, durable and damage resistant: The interlocking fit between the connecting part and the groove provides initial positioning accuracy for splicing; the mortar injected into the main and secondary grouting channels forms a "rigid and flexible" connection system between adjacent wall panels, filling gaps and transferring stress; the elastic sealing strip provides double sealing to prevent water and air penetration; the staggered reinforcing protrusions can disperse stress; the multi-structure collaboration makes the wall panel splicing nodes strong and well-sealed, effectively avoiding cracking and leakage risks, ensuring long-term stable use of the wall, and significantly improving building durability;

[0013] 2. Functional integration, comfort and energy saving: The four-layer composite structure has precise division of labor, the decorative layer is formed in one piece, eliminating the need for later decoration and painting, the thermal insulation layer has a low thermal conductivity, which prevents heat from entering in summer and locks in the temperature in winter, helping the building reduce the energy consumption of air conditioning and heating, and the sound insulation layer efficiently absorbs sound waves, significantly reducing external noise and creating a quiet indoor environment. The functional integration and performance far exceed that of traditional single wall panels, greatly improving living comfort and building energy efficiency.

[0014] 3. Convenient installation, improved efficiency and reduced costs: The lifting holes, combined with wear-resistant sleeves, enable precise and efficient crane lifting operations, reducing the risk of damage to wall panels during transportation. The integrated process of "insertion positioning + grouting sealing" during splicing reduces repeated manual adjustments. Decorative covers quickly conceal the lifting holes, saving extra time for repairs and beautification. Compared with traditional wall panels, installation efficiency is improved, the construction cycle is shortened, and labor and time costs are reduced, making it suitable for the rapid construction needs of prefabricated buildings.

[0031] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0032] Please refer to Figures 1 to 6 Example 1:

[0033] This utility model proposes a prefabricated concrete wall panel, comprising: a wall panel body, which is a layered composite structure, and the wall panel body includes, from the outside to the inside, a decorative layer 4, a thermal insulation layer 3, a sound insulation layer 2, and a concrete slab 1. Adjacent wall panel bodies are spliced ​​and assembled with mortar filling at the splice joints. The wall panel body has a lifting hole inside, which penetrates the decorative layer 4, the thermal insulation layer 3, the sound insulation layer 2, and the concrete slab 1. A decorative plug 5 is fixedly installed on the outside of the lifting hole, and a wear-resistant sleeve 6 is provided on the inner wall of the lifting hole.

[0034] Among them, the sound insulation layer 2 is made of sound insulation felt, the thermal insulation layer 3 is made of extruded polystyrene foam board, and the sound insulation layer 2 and the thermal insulation layer 3 are bonded and fixed with epoxy resin adhesive. In use, the various layers of the wall panel body 1 work together, the decorative layer 4 meets the aesthetic requirements of the building, the thermal insulation layer 3 blocks heat transfer, the sound insulation layer 2 absorbs sound waves and reduces noise, and the concrete slab body 1 provides structural strength support, realizing the integrated function.

[0035] The concrete slab 1 has a raised connecting part 101 on one side and a groove 102 on the other side that matches the connecting part 101. The connecting part 101 of the adjacent wall panel is inserted into the groove 102. In use, the adjacent wall panels are spliced ​​by the double protection of "connecting part 101 insertion + mortar grouting". The connecting part 101 has a grouting main channel 1011 inside and a grouting secondary channel 1012 on the side of the grouting main channel 1011. The connecting part 101 has a pre-set grouting main channel 1011 and grouting secondary channel 1012. The mortar accurately fills the gaps and strengthens the joint strength. The sides of the concrete slab 1 on both sides of the groove 102 are provided with elastic sealing strips 1021. The elastic sealing strips 1021 are made of aging-resistant rubber material. The elastic sealing strips 1021 not only prevent grout leakage to ensure clean construction, but also prevent rainwater and air penetration, thereby improving the sealing and waterproofing of the wall.

[0036] The connecting part 101 has a groove 102 on the outside and a reinforcing protrusion 1022 on the inside. The reinforcing protrusions 1022 of the connecting part 101 and the groove 102 are staggered. In use, the splicing stress after grouting is dispersed by the principle of structural mechanics, which avoids cracking of the joint, greatly improves the durability of the connection, and reduces the damage to the wall panel caused by hoisting operations. The hole is equipped with a decorative plug 5, which can quickly cover the hoisting hole after construction to maintain the integrity and decoration of the wall appearance.

[0037] The working principle of this embodiment is as follows: Before construction, the appearance, dimensions, and material certificates of the precast wall panels are inspected. The building floor is cleaned and leveled, and installation positioning control lines are marked. During construction, the crane hook is inserted into the wall panel lifting hole to lift it, aligning the wall panel connection 101 with the groove 102 of the adjacent structure. Adjustments are made to ensure that the verticality and flatness meet the requirements. The elastic sealing strips 1021 on both sides of the groove 102 are checked. High-strength mortar is injected from the main grouting channel 1011 using a low-pressure grouting pump. After the grouting auxiliary channel 1012 continuously discharges mortar and is full, the grouting port is stopped and sealed. The overflowing mortar is cleaned up, and the grouting mortar is then ready for use. Once the strength reaches the design value, the decorative plug 5 is installed. Finally, the connection nodes and wall performance are tested, and the data is organized and archived. After completion, subsequent processes such as water and electricity pipeline pre-embedding can be connected. Adjacent wall panels rely on the connection part 101 and the groove 102 to form a preliminary mechanical interlocking positioning. The staggered strengthening protrusion 1022 increases the contact area and disperses stress. High-strength mortar is injected into the main grouting channel 1011 and the secondary channel. After hardening, the adjacent wall panels form a rigid bond at the splicing node, which enhances the connection strength and durability. The elastic sealing strip 1021 deforms under pressure, which not only prevents grout leakage but also maintains the sealing of the node when the building undergoes micro-deformation. In the layered composite structure, the decorative layer 4 has a decorative function from the factory, the thermal insulation layer 3 uses a low thermal conductivity to block heat transfer, the sound insulation layer 2 attenuates sound wave energy through a porous structure and damping characteristics, the concrete slab provides structural load-bearing and auxiliary sound insulation and fireproof performance, and the layers work together to build an integrated "structure-function" system. During hoisting, the hoisting hole, together with the wear-resistant sleeve 6, provides a force point for the crane hook, and the decorative cover 5 is used to cover the hoisting hole later to restore the aesthetics of the wall.
