Description

Technical Field

[0001] This utility model relates to the field of prefabricated wall panel technology, and more specifically, to a prefabricated wall panel for green building design. Background Technology

[0002] Precast wall panels are components manufactured in factories for use in building assembly, typically composed of concrete, steel reinforcement, and other materials. The application of precast wall panels in green building design offers significant environmental, energy-saving, and economic benefits, and is an important means of achieving green building goals.

[0003] Patent CN221567647U discloses a prefabricated wall panel for green building design. When assembling two adjacent wall panels, the second wall panel is pushed closer to the first wall panel, causing the fixing box to gradually enter the recess. Then, the second wall panel is pushed downwards, causing the fixing slot to enter between the connecting protrusion and the stabilizing block. At this point, the stabilizing block enters the fixing groove, and the first and second wall panels are connected through the cooperation of the fixing box and the stabilizing block. Two adjacent first wall panels are also fixed using fixing clips and slots. However, the above-mentioned methods of fixing adjacent wall panels, using fixing boxes and stabilizing blocks or fixing clips and slots respectively, are prone to breakage during the connection process due to the rigid materials used in these connections, affecting the connection between adjacent wall panels. Furthermore, even after assembling the wall panels using these methods, subsequent decoration may still require drilling or other operations. Summary of the Invention

[0004] To overcome the shortcomings mentioned above, this utility model aims to provide a prefabricated wall panel for green building design.

[0005] A precast wall panel for green building design includes a wall panel body with outwardly extending steel reinforcement segments; a steel reinforcement skeleton arranged between two adjacent wall panel bodies, wherein the steel reinforcement segments hook the steel reinforcement skeleton; a cast-in-place concrete layer is also arranged between two adjacent wall panel bodies, wherein the steel reinforcement segments and the steel reinforcement skeleton are arranged within the cast-in-place concrete layer; and the wall panel body and the steel reinforcement skeleton are respectively provided with a first connection structure and a second connection structure.

[0006] Furthermore, the wall panel body has several pre-embedded connection structures, which are used to connect the decorative layer.

[0007] Furthermore, the free ends of the steel bars extending outward from the wall panel body are downward-curved hooks, used to hook the steel bar skeleton.

[0008] Furthermore, the reinforcing steel cage includes several reinforcing steel rings arranged at equal intervals, and vertical reinforcing steel bars inserted into and fixedly connected to the reinforcing steel rings.

[0009] Furthermore, the connecting structure three is provided at intervals on the steel bar segments and steel bar rings, and the connecting structure three is used to connect the decorative layer.

[0010] Furthermore, the first connection structure includes an internally threaded tube and receiving grooves at both ends, wherein the internally threaded tube and the two receiving grooves are an integral structure; the second and third connection structures are the same as the first connection structure.

[0011] Furthermore, both ends of the internally threaded tube may be optionally threaded with a screw or a fastener with an added decorative layer.

[0012] Furthermore, the outer wall of the internally threaded tube is fixed to the top of the reinforcing bar segment or reinforcing bar ring.

[0013] Furthermore, on one side of the wall panel body, the connecting structure is fixedly connected to the steel bar segment at three equal intervals.

[0014] Furthermore, in the steel reinforcement cage, the two connecting structures are fixed to the steel reinforcement ring at equal intervals.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This green building design utilizes precast wall panels, connecting adjacent panels via steel reinforcement segments extending from the panel body to a steel reinforcement framework, and then a cast-in-place concrete layer. Embedded connection structures within the wall panels allow for the subsequent installation of decorative layers, using threaded connections for flexible installation of the decorative layer fasteners. When not in use, the threaded connections rely solely on bolts. These embedded connection structures within the wall panels, along with the connection structures between the panels, avoid the breakage issues associated with rigid material clamping in traditional connection methods, and also eliminate the need for drilling during subsequent decorative installation.

[0017] This green building design utilizes prefabricated wall panels with multiple pre-embedded connection structures within the panel body. These threaded connections allow for flexible installation of decorative layer fasteners after the wall panels are prefabricated, eliminating the need for drilling or other destructive operations. Multiple connection structures are also strategically placed between adjacent wall panels, increasing the available installation locations for the decorative layer and offering greater flexibility in application.

[0029] 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.

[0030] like Figures 1-4 As shown, this embodiment provides a prefabricated wall panel for green building design, including a wall panel body 1, with steel reinforcement segments 11 extending outward from the wall panel body 1; a steel reinforcement skeleton 2 is arranged between two adjacent wall panel bodies, and the steel reinforcement segments 11 hook the steel reinforcement skeleton 2; a cast-in-place concrete layer is also arranged between two adjacent wall panel bodies 1, and the cast-in-place concrete layer contains the steel reinforcement skeleton 2 and the steel reinforcement segments 11 hooked on both sides of the two adjacent wall panel bodies 1.

[0031] Specifically, the wall panel body 1 has several pre-embedded connecting structures 3, which are used to connect the decorative layer.

[0032] In this embodiment, the wall panel body 1 is formed by precast concrete along with a steel mesh. Within the wall panel body, steel bar segments 11 extend outwards, extending from some of the steel bars in the internal steel mesh. These steel bar segments 11 are horizontally arranged. The free ends of the steel bar segments 11 are downward-curved hooks used to hook onto the steel reinforcement skeleton 2. The steel reinforcement skeleton 2 includes several steel bar rings 21 arranged at equal intervals vertically and vertically, and vertical steel bars 22 inserted into and fixedly connected to the steel bar rings 21.

[0033] In this embodiment, connecting structures 3 and 5 are spaced apart on the reinforcing bar segments 11 and reinforcing bar rings 21, and are used to connect the decorative layer. In this embodiment, the connecting structures 3 and 5 are fixedly connected to the reinforcing bar segments 11 at equal intervals on one side of the wall panel body 1. In the reinforcing bar skeleton 2, connecting structures 2 and 4 are fixedly connected to the reinforcing bar rings 21 at equal intervals. Alternatively, connecting structures 3 and 5 or connecting structures 2 and 4 can be installed at different positions on the reinforcing bar segments 11 and reinforcing bar rings 21 according to actual needs, allowing for flexible placement of the connecting structures 3 and 5.

[0034] To be more specific, such as Figures 5-6 As shown, connection structure 3 includes an internally threaded pipe 31 and receiving grooves 32 at both ends, with the internally threaded pipe 31 and the two receiving grooves 32 forming an integral structure. The receiving groove 32 is a cylindrical structure with its slots facing outwards, facilitating the tightening of the threaded rod connected to the internally threaded pipe. Connection structures 4 and 5 have the same structure as connection structure 3. During the prefabrication of the wall panel body 1, a steel mesh is laid between two oppositely arranged mold plates before pouring. Due to the placement of the receiving grooves 32, the outer end face of the receiving grooves 32 abuts against the mold plates, preventing concrete from entering the receiving grooves 32. After the wall panel body 1 is poured, the receiving grooves 32 remain in their slotted state. It is worth noting that before prefabricating the wall panel body, rubber blocks of a suitable shape can be placed in the receiving grooves 32 beforehand; these blocks can be removed after pouring.

[0035] In connection structure 3, both ends of the internally threaded tube 31 are optionally threadedly connected to either a screw 33 or a fastener for the decorative layer. When no decorative layer or other structural connection is required, the internally threaded tube 31 is simply threaded onto the screw 33. When the decorative layer needs to be installed, the screw 33 is unscrewed, and the threaded fastener for the decorative layer is connected. Because both ends of connection structure 3 are connected to screws 33, the decorative layer can be selectively installed on both sides of the wall panel. It is worth noting that multiple connection structures 3 are provided on the wall panel body 1, and multiple connection structures 4 and 5 are also provided between two wall panel bodies 1, allowing for the connection of the decorative layer fastener at multiple locations.

[0036] In this embodiment, the internally threaded pipe 31 is a steel pipe with internal threads, and the outer wall of the internally threaded pipe 31 is fixed to the top of the reinforcing bar segment 11 or the reinforcing bar ring 21 by welding.

[0037] The prefabricated wall panel for green building design provided in this embodiment achieves a stable connection between adjacent wall panel bodies 1 by connecting the steel reinforcement segments 11 extending from the wall panel body 1 to the steel reinforcement skeleton 2 and then casting a concrete layer. A pre-embedded connection structure 3 within the wall panel body 1 is used for subsequent installation of a decorative layer, with the decorative layer fasteners installed flexibly via threaded connections. When not in use, the threaded connection is achieved using screws 33. The pre-embedded connection structure 3 within the wall panel body 1, along with the connection structures 4 and 5 arranged between two wall panel bodies 1, avoids the problem of easy breakage when rigid materials are engaged in traditional connection methods, and also eliminates the need for drilling during subsequent decorative installation.

[0038] The precast wall panel for green building design provided in this embodiment connects two adjacent wall panel bodies 1 by means of a connection between the steel reinforcement segments 11 extending from the wall panel body 1 and the steel reinforcement skeleton 2. Specifically, the opposing steel reinforcement segments 11 of the two wall panel bodies 1 hook onto opposite sides of the steel reinforcement 21 in the steel reinforcement skeleton 2 via hook-like structures. Then, concrete is poured in place. The extended steel reinforcement segments 11, together with the steel reinforcement skeleton 2, and the connecting structures 4 and 5 arranged at the connection point, are all cast into the concrete, thus achieving fixation. This connection method is more stable and less prone to breakage than rigid interlocking structures, improving the reliability of the connection between adjacent wall panels. Through the connection of the steel reinforcement segments 11 and the steel reinforcement skeleton 2, and the pouring of the cast-in-place concrete layer, the connection process between the wall panel bodies 1 is simplified, and the firmness of the connection between adjacent wall panel bodies 1 is ensured.

[0039] The prefabricated wall panel for green building design provided in this embodiment has multiple pre-embedded connection structures 3 in the wall panel body 1. Through threaded connections, decorative layer fasteners can be flexibly installed after the wall panel is prefabricated, eliminating the need for destructive operations such as drilling. Multiple sets of connection structures 4 and 5 are also arranged between two adjacent wall panel bodies 1, increasing the selectable installation locations for the decorative layer and providing flexibility in application. The threaded connection methods of the above-mentioned connection structures facilitate the installation of the decorative layer and improve overall installation efficiency.

[0040] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
