Description

Technical Field

[0001] This utility model relates to the field of precast concrete wall panel technology, specifically a precast concrete composite wall panel for prefabricated housing construction. Background Technology

[0002] Precast concrete composite wall panels, also known as precast integrated panels, are building materials that are prefabricated and integrated with multiple structural layers in a factory. Thanks to the advantages of manufacturing on mechanized and automated production lines in factories, these wall panels ensure consistent and stable quality for each piece. Precast concrete composite wall panels not only integrate decoration, insulation, waterproofing, flame retardancy, and sound insulation functions, meeting the diverse needs of modern buildings for wall materials, but their convenient installation method also significantly shortens the construction cycle, reduces on-site wet work, saves labor, and improves construction efficiency. In existing prefabricated concrete composite wall panels for assembled housing, to ensure the insulation effect, concrete panels are usually spliced ​​with multiple layers of boards such as insulation boards. However, after prolonged use, the spliced ​​multiple layers are prone to separation and detachment, leading to poor insulation, wall deformation, and even exterior wall detachment due to deformation. Utility Model Content

[0003] Based on this, the purpose of this utility model is to provide a precast concrete composite wall panel for prefabricated housing construction, so as to solve the technical problem that after long-term use, the multi-layer panels are easy to separate and fall off, resulting in poor thermal insulation, wall deformation and external wall detachment.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a precast concrete composite wall panel for prefabricated housing construction, comprising a concrete slab, an adhesive mortar on one side of the concrete slab, an insulation board on one side of the adhesive mortar, insulation mortar on one side of the insulation board, a galvanized welded wire mesh on one side of the insulation mortar, a fixing plate on the outer surface of the galvanized welded wire mesh, an anchor rod at the bottom of the fixing plate, a snap ring on the anchor rod, a snap groove on the outer surface of the snap ring, and an insert rod snapped into the snap groove.

[0005] By adopting the above technical solution, the concrete slab, as the main load-bearing part of the wall panel, provides a solid structural foundation, and its high strength and durability ensure the stability and safety of the wall panel in long-term use.

[0006] Furthermore, both the concrete slab and the insulation board are serrated, with the serrations on both sides of the insulation board being staggered.

[0007] By adopting the above technical solution, both the concrete slab and the insulation board are designed with grooves, which increases the contact area between them, helps to improve the bonding effect of the bonding mortar, ensures a firm connection between the concrete slab and the insulation board, and reduces the risk of separation and detachment due to material aging or thermal expansion and contraction.

[0008] Furthermore, the anchor rods are provided in two sets, with six anchor rods in each set.

[0009] By adopting the above technical solution, the installation of two sets of anchor rods is equivalent to adding two stable support points in the wall panel, which helps to enhance the overall stability of the wall panel. When subjected to external forces, the two sets of anchor rods can share the load and reduce the risk of single-point stress.

[0010] Furthermore, the six anchor rods are evenly spaced and matched with the longitudinal position of the grooves in the concrete slab and insulation board.

[0011] By adopting the above technical solution, the six anchor rods are evenly spaced, which makes the load distribution on the wall panel more balanced, helps to prevent local damage caused by load concentration, and improves the overall load-bearing capacity and stability of the wall panel.

[0012] Furthermore, two snap-fit ​​rings are provided, and the two snap-fit ​​rings are adapted to the lateral position of the grooves of the concrete slab and the insulation board.

[0013] By adopting the above technical solution, the addition of two snap-fit ​​rings increases the connection points between the anchor rod and the concrete slab and insulation board, thereby enhancing the overall connection stability of the wall panel and helping to prevent the wall panel from falling off or loosening due to single-point connection failure.

[0014] Furthermore, the interior of the concrete slab is provided with multiple truss steel bars running from top to bottom through its left and right ends.

[0015] By adopting the above technical solution, the truss reinforcement serves as the internal skeleton of the concrete slab, significantly enhancing the structural strength of the wall panel. These reinforcements can withstand and distribute loads from different directions, ensuring the stability of the wall panel under stress.

[0016] In summary, the present invention has the following main advantages:

[0017] 1. This utility model, by incorporating anchor rods, snap rings, and insert rods, significantly enhances the connection stability and fixation between the wall panel and the building structure. The anchor rods penetrate deep into the wall or building structure, and the dual locking mechanism of the snap rings and insert rods ensures that the wall panel will not detach or loosen due to external forces during prolonged use. This improves the safety of the wall panel and extends its service life.

[0018] 2. This utility model effectively improves the thermal insulation performance and heat insulation effect of the wall panel by setting a grooved concrete slab and insulation board. The grooves increase the contact area and mechanical interlocking force between the concrete slab and insulation board, making them more tightly bonded and reducing the possibility of heat transfer and loss. Multiple truss steel bars running through the left and right ends of the concrete slab are set inside. These steel bars form the internal skeleton of the concrete slab, enhancing the overall structural strength and stability of the wall panel. Attached Figure Description

For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0027] The embodiments of this utility model will be described below based on its overall structure.

[0028] A precast concrete composite wall panel for prefabricated housing construction, such as Figures 1-4 As shown, the wall panel includes a concrete slab 1, with adhesive mortar 2 on one side, an insulation board 3 on one side of the adhesive mortar 2, insulation mortar 4 on one side of the insulation board 3, and a galvanized welded wire mesh 5 on one side of the insulation mortar 4. A fixing plate 6 is provided on the outer surface of the galvanized welded wire mesh 5, and an anchor rod 7 is provided at the bottom of the fixing plate 6. A snap-fit ​​ring 8 is provided on the anchor rod 7, and a snap-fit ​​groove 9 is formed on the outer surface of the snap-fit ​​ring 8. A plug rod 10 is snapped into the snap-fit ​​groove 9. The concrete slab 1 serves as the main load-bearing component of the wall panel, providing a solid structural foundation. Its high strength and durability ensure the stability and safety of the wall panel during long-term use. The plug rod 10, as a connector, is snapped into the snap-fit ​​groove 9, tightly connecting the wall panel to the building structure. It provides additional support and fixing points, ensuring the stability and safety of the wall panel during long-term use.

[0029] See Figure 1 , Figure 2 , Figure 4 Both the concrete slab 1 and the insulation board 3 are serrated, with the serrations on both sides of the insulation board 3 being staggered. This serrated design increases the contact area between the two, which helps improve the bonding effect of the bonding mortar 2, ensuring a firm connection between the concrete slab 1 and the insulation board 3. It also reduces the risk of separation and detachment due to material aging or thermal expansion and contraction. The staggered serrations on both sides of the insulation board 3 help reduce the thermal bridging effect, effectively preventing heat transfer, thereby reducing energy consumption and improving the building's energy efficiency.

[0030] See Figure 1 , Figure 4There are two sets of anchor rods 7, with six anchor rods in each set. The two sets of anchor rods 7 are equivalent to adding two stable support points in the wall panel, which helps to enhance the overall stability of the wall panel. When subjected to external forces, the two sets of anchor rods 7 can share the load, reducing the risk of single-point stress. The multiple anchor rods 7 increase the number of connection points, making the connection between the wall panel and the building structure tighter and less prone to loosening or falling off.

[0031] See Figure 1 , Figure 4 The six anchor rods 7 are evenly spaced and matched with the longitudinal position of the grooves of the concrete slab 1 and the insulation board 3. The evenly spaced six anchor rods 7 make the load distribution on the wall panel more balanced, which helps to prevent local damage caused by load concentration and improves the overall load-bearing capacity and stability of the wall panel. The matching of the anchor rods 7 with the longitudinal position of the grooves of the concrete slab 1 and the insulation board 3 ensures the firmness and stability of the connecting parts, so that the anchor rods 7 can be better embedded in the grooves to form a stable connection and prevent loosening or falling off due to external forces.

[0032] See Figure 1 , Figure 3 There are two snap-fit ​​rings 8, which are adapted to the transverse position of the toothed grooves of the concrete slab 1 and the insulation board 3. The addition of two snap-fit ​​rings 8 increases the connection points between the anchor rod 7 and the concrete slab 1 and the insulation board 3, thereby enhancing the overall connection stability of the wall panel and helping to prevent the wall panel from falling off or loosening due to single-point connection failure. The transverse position of the toothed grooves of the two snap-fit ​​rings 8 allows the load to be distributed more evenly on the wall panel, which helps to reduce local stress concentration and improve the load-bearing capacity and durability of the wall panel.

[0033] See Figure 1 The interior of the concrete slab 1 has multiple truss steel bars 11 running through its left and right ends from top to bottom. The truss steel bars 11 serve as the internal skeleton of the concrete slab 1, significantly enhancing the structural strength of the wall panel. These steel bars can withstand and distribute loads from different directions, ensuring that the wall panel remains stable under stress. The multiple truss steel bars 11 running through the left and right ends of the concrete slab 1 form a stable support system, which helps to prevent the wall panel from deforming or cracking due to external forces, thereby improving the overall stability.

[0034] The implementation principle of this utility model is as follows: First, truss steel bars 11 are laid in the mold, and then concrete is poured. After the concrete slab 1 solidifies, it is taken out of the mold. Then, adhesive mortar 2 is applied to the toothed groove direction of the concrete slab 1. Then, insulation board 3 is laid. Then, insulation mortar 4 is applied to the other side of the insulation board 3. Then, galvanized welded wire mesh 5 is laid on the outside of the insulation mortar 4. Then, anchor rod 7 is inserted into the preset hole. Then, insert rod 10 is inserted from both sides and the insert rod 10 passes through the snap-fit ​​groove 9. When inserting, adhesive is added into the hole to fix the anchor rod 7 and the insert rod 10.

[0035] All parts not covered in this utility model are the same as or can be implemented using existing technologies, and will not be described in detail here.

[0036] Although embodiments of the present invention have been shown and described, these specific embodiments are merely explanations of the present invention and are not intended to limit the invention. The specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions, and variations to the embodiments as needed without departing from the principles and spirit of the present invention, provided that such modifications, substitutions, and variations are within the scope of the claims of the present invention and are protected by patent law.
