Abstract
Description
Technical Field
[0001] This invention belongs to the field of building construction technology, and in particular relates to a prefabricated building composite wall panel structure and its construction method. Background Technology
[0002] With the transformation and upgrading of my country's construction industry, the development of prefabricated buildings is being vigorously promoted, with innovative prefabricated building design, optimized component production, and improved prefabricated construction levels clearly identified as future directions for the industry. Prefabricated shear wall structures are one of the most widely used structural systems on the market; simplifying the connection details and improving construction efficiency are directions for improvement.
[0003] Composite wall panels integrate the structural and insulation functions of a wall by prefabricating the inner and outer leaves of a shear wall in a factory and integrating insulation materials within the wall. This reduces on-site construction procedures and improves construction efficiency. A search revealed CN111270793A, which proposes an integrated insulation double-sided composite wall panel and its construction method. The specification
[0143] states: "The prefabricated double-sided composite component includes insulation connectors, a reinforcing cage, and sequentially stacked outer insulation layer, outer leaf plate, and inner leaf plate. The outer insulation layer is connected to the outer leaf plate via insulation connectors. The two ends of the reinforcing cage are anchored to the inner and outer leaf plates respectively, connecting the inner and outer leaf plates as a whole. There is a distance between the inner and outer leaf plates to form a cavity. Bolt holes for installation bolts are pre-embedded on the inner leaf plate." This technical solution obtains a composite structure of reinforcing cage, inner leaf plate, and outer leaf plate through prefabrication. However, the overall structure is large and difficult to assemble with the upper and lower structural steel bars, and on-site construction (adjusting verticality and other supports) is challenging. Summary of the Invention
[0004] The technical problem to be solved by the present invention is to provide a novel composite wall panel structure that enables rapid and reliable on-site connection between double-sided composite slabs and steel cages.
[0005] To solve the above-mentioned technical problems, the inventors, through practice and summarization, derived the technical solution of this invention, which adopts the following technical solution:
[0006] A prefabricated composite wall panel structure for buildings includes:
[0007] Central steel cage,
[0008] Composite slab, the composite slab is provided with two sets distributed on both sides of the central steel cage;
[0009] The connector is located on one side of the two sets of composite plates. An upper rotating plate is mounted on the connector via a rotating shaft one, and a lower rotating plate is mounted via a rotating shaft two. Elastic plates are provided on the sides of the upper and lower rotating plates closest to the composite plates. The sides of the upper and lower rotating plates are connected by a connecting strip, with both ends of the connecting strip movably connected to the corresponding rotating plates. A rotating groove is provided on the outer wall of the upper rotating plate, within which a spring body and a socket are installed. A socket is provided on the outer wall of the lower rotating plate. Both the socket and the socket are T-shaped structures and are mutually compatible, used to fix the upper and lower rotating plates to the central reinforcing cage. A release element is installed on the upper rotating plate, used to release the socket after the free ends of the upper and lower rotating plates contact each other. Under the action of the spring body, the socket adapts to the socket to complete the connection and fixation with the central reinforcing cage.
[0010] In a further technical solution, rolling elements are provided on both ends of the connecting strip. Connecting ports are evenly distributed on the side of the upper and lower rotating plates near the composite plate. The sidewall of the connecting port has a constraint guide groove. The constraint guide groove is a T-shaped structure for the rolling elements to be installed movably. A stop bar is installed at the groove of the connecting port to constrain the rolling elements in the constraint guide groove.
[0011] In a further technical solution, a fixing plate is installed on the outer wall of the lower rotating plate. The fixing plate has a U-shaped structure, and a ratchet is installed on the side of the fixing plate facing the lower rotating plate. The socket is provided with constraint teeth, and the constraint teeth and the ratchet are positioned correspondingly and adapted to each other.
[0012] In a further technical solution, the release component includes a fixed plate two and a traction rope fixedly installed on the upper rotating plate. The fixed plate two has a U-shaped structure and a traction body is installed on the fixed plate two. One end of the traction body and the traction rope are connected. The traction body slides on the fixed plate two and moves in a direction perpendicular to one side of the lower ratchet. The other end of the traction rope is fixed on the upper rotating plate.
[0013] In a further technical solution, wire mesh is provided inside both sets of composite plates. Embedded bodies are pre-embedded on the opposite side of the two sets of wire mesh. Connecting cylinders are provided on the embedded bodies. The connecting cylinders pass through the wire mesh and are exposed on the outside of the composite plates. A traction column is connected between two corresponding connecting cylinders. Traction bodies are provided at both ends of the traction column for connecting with the embedded bodies.
[0014] In a further technical solution, an elastic clamping body is installed inside the pre-embedded body. The elastic clamping body includes mounting holes distributed on the outside of the pre-embedded body. A set screw, an elastic element, and a clamping head are installed sequentially from the outside to the inside of the mounting holes. A tapered guide cone structure is provided at the end of the traction column. A clamping ring is provided at the root of the tapered guide cone structure. The clamping head and the clamping ring are adapted to constrain the traction column.
[0015] In a further technical solution, the connecting cylinder is larger at one end and smaller at the other, with the larger end exposed on the outside of the composite plate.
[0016] In a further technical solution, each of the two sets of composite plates has a number of equally spaced vertical connecting ribs on its opposite side. The vertical connecting ribs have a trapezoidal structure, and the width of the vertical connecting ribs on the side closer to the composite plate is greater than the width on the side farther away from the composite plate.
[0017] A construction method for a prefabricated building composite wall panel structure includes:
[0018] Step 1, Construction of the central steel reinforcement cage
[0019] The installation boundary line of the composite slab and the boundary line of the position of the central steel cage are marked on the foundation layer by drawing lines, and the central steel cage is obtained by binding the vertical steel bars of the foundation layer.
[0020] Step 2, Construction of a set of composite slabs
[0021] Steel structure angle brackets are installed at the boundary line of the composite slab installation, and the top of the steel structure angle brackets is adjusted to be on the same horizontal plane. Then the transverse reinforcement of the central steel cage is adjusted to ensure that the positions of the transverse reinforcement and the connectors correspond.
[0022] First, install the tie column inside the connecting tube of one set of composite slabs. Then, push the composite slab horizontally and longitudinally along the top of the steel structure angle bracket close to the middle steel cage until the upper and lower rotating plates are wrapped around the transverse steel bars, thus completing the connection and fixation of the composite slab and the middle steel cage.
[0023] Another set of composite plates is pushed horizontally and longitudinally along the top of the steel structure angle brackets towards the middle of the reinforcing cage until the upper and lower rotating plates are wrapped around the transverse reinforcing bars. At the same time, the pulling body enters the connecting cylinder and is constrained and fixed by the elastic clamping body.
[0024] Step 3, Connector Installation
[0025] In step 2, when the connector approaches the transverse reinforcement longitudinally, the lower and upper rotating plates will first contact the transverse reinforcement. Then, as the composite plate continues to approach, the lower and upper rotating plates will rotate around their respective rotation axes, and the elastic plate will undergo elastic deformation until the free ends of the lower and upper rotating plates approach and abut. At this time, the pulling rope will drive the pulling body and the ratchet to separate. Then, the spring body will push the socket body out. After the ends of the lower and upper rotating plates complete the contact and abutment, the socket body will be inserted into the socket under the action of the spring body, and the constraining teeth will constrain and restrict the socket body to prevent it from separating from the transverse reinforcement during concrete pouring.
[0026] Step 4, Installation of tie columns
[0027] When the tapered guide cone structure at the end of the traction column passes through the connecting cylinder and enters the embedded body, the tapered guide cone structure will first be used to push the clamping head outward and compress the elastic component. When the clamping head and the clamping ring are aligned, the elastic component will push the clamping head outward into the clamping ring to complete the connection between the traction column and the corresponding embedded body.
[0028] Step 5: Pour concrete;
[0029] After adjusting the verticality of the two sets of composite slabs to meet the design requirements, the gap between the composite slabs and the foundation structure layer is sealed, and concrete is poured in place in the support area between the two sets of composite slabs.
[0030] Compared with the prior art, the present invention has the following beneficial effects:
[0031] This invention employs connectors for assembling composite slabs and a central reinforcing cage, utilizes upper and lower rotating plates to wrap the reinforcing bars, and uses sockets to constrain and fix the upper and lower rotating plates, preventing loosening of the reinforcing bars and thus ensuring structural stability. Additionally, constraining teeth are used to constrain and fix the sockets, preventing loosening, and a tie column in the central section ensures long-term structural stability.

[0044] Example 1
[0045] like Figure 1 As shown, a prefabricated building composite wall panel structure includes:
[0046] 10 steel reinforcement cages in the middle.
[0047] Composite slab 20, with two sets of materials distributed on both sides of the central steel cage 10;
[0048] like Figures 2 to 4 As shown, a connector 30 is arranged on one side of the two sets of composite plates 20. An upper rotating plate 40 is mounted on the connector 30 via a rotating shaft one, and a lower rotating plate 50 is mounted on the connector 30 via a rotating shaft two. An elastic plate 60 is provided on the side of the upper rotating plate 40 and the lower rotating plate 50 closest to the composite plate 20. The sides of the upper rotating plate 40 and the lower rotating plate 50 closest to the composite plate 20 are connected by a connecting strip 70. Both ends of the connecting strip 70 are movably connected to the corresponding rotating plates. A rotating groove 41 is provided on the outer wall of the upper rotating plate 40. A spring body 42 and a socket body 43 are installed inside the upper rotating plate 40. A socket 51 is provided on the outer wall of the lower rotating plate 50. Both the socket body 43 and the socket 51 are T-shaped structures and are mutually compatible. They are used to fix the upper rotating plate 40 and the lower rotating plate 50 to the middle steel cage 10. A release member 80 is installed on the upper rotating plate 40. The release member 80 is used to release the socket body 43 after the free ends of the upper rotating plate 40 and the lower rotating plate 50 come into contact. Under the action of the spring body 42, the socket body 43 and the socket 51 are adapted to complete the connection and fixation with the middle steel cage 10.
[0049] In specific implementation, the connector 30 is installed on the opposite sides of the two sets of composite plates 20. After the middle steel cage 10 is tied, the composite plate 20 is installed longitudinally (close to the middle steel cage 10). During the approach of the connector 30, the lower rotating plate 50 and the upper rotating plate 40 will first contact the transverse steel bars. Then, as the composite plate 20 continues to approach, the lower rotating plate 50 and the upper rotating plate 40 will rotate around their respective rotation axes. At the same time, the elastic plate 60 will undergo elastic deformation until the free ends of the lower rotating plate 50 and the upper rotating plate 40 approach and abut. At this time, the release member 80 will disengage from the socket 43. Then, the spring body 42 will push the socket 43 outward. After the ends of the lower rotating plate 50 and the upper rotating plate 40 complete the contact and abutment, the socket 43 will be inserted into the socket 51 under the action of the spring body 42.
[0050] Example 2
[0051] In the wall panel structure, such as Figure 6-8 As shown, rolling elements 71 are provided on both ends of the connecting strip 70. Connecting ports 73 are evenly distributed on the side of the upper rotating plate 40 and lower rotating plate 50 near the composite plate 20. A constraint guide groove 72 is provided on the side wall of the connecting port 73. The constraint guide groove 72 is a T-shaped structure for the rolling elements 71 to be movably installed. A stop bar 74 is installed at the opening of the connecting port 73 to constrain the rolling elements 71 within the constraint guide groove 72. The connecting strip 70, in conjunction with the upper and lower rotating plates, completes the wrapping of the transverse reinforcing bars of the central steel reinforcement cage 10. The upper and lower rotating plates and the connecting strip 70 form a circular structure.
[0052] Example 3
[0053] In the aforementioned wall panel structure, to prevent detachment of the transverse reinforcing bars during concrete pouring, such as... Figure 3 , 4 As shown, a fixing plate 52 is installed on the outer wall of the lower rotating plate 50. The fixing plate 52 has a U-shaped structure, and a ratchet rack 53 is installed on the side of the fixing plate 52 facing the lower rotating plate 50. The socket body 43 is provided with constraint teeth 431. The constraint teeth 431 and the ratchet rack 53 are corresponding and compatible with each other. The constraint teeth 431 constrain and fix the socket body 43 to prevent the upper rotating plate 40 and the lower rotating plate 50 from being released.
[0054] Example 4
[0055] In the wall panel structure, in order to selectively release the socket 43, such as Figures 3 to 6As shown, the release component 80 includes a fixed plate 81 and a pull rope 82 fixedly mounted on the upper rotating plate 40. The fixed plate 81 has a U-shaped structure, and a pull body 83 is mounted on the fixed plate 81. One end of the pull body 83 is connected to one end of the pull rope 82. The pull body 83 is slidably fitted on the fixed plate 81 and its direction of movement is perpendicular to one side of the lower ratchet rack 53. Figure 5 As shown, the free end of the traction body 83 is used to constrain the constraint teeth 431 of the upper rotating plate 40. A spring tube is provided on the outer side of the traction body 83. The top of the traction body 83 passes through the second fixing plate 81 and is connected to a large head. The large head is connected to the traction rope 82. At the same time, a guide wheel is provided on the second fixing plate 81. The guide wheel is used for the upper traction rope 82. The other end of the traction rope 82 is fixed to the upper rotating plate 40. When the free ends of the lower rotating plate 50 and the upper rotating plate 40 approach and abut, the traction rope 82 will drive the traction body 83 and the ratchet 53 to disengage. Then, the spring body 42 will push the socket 43 outward. After the ends of the lower rotating plate 50 and the upper rotating plate 40 complete the contact and abutment, the socket 43 will be inserted into the socket 51 under the action of the spring body 42, and the constraint teeth 431 will constrain and restrict the socket 43 to prevent it from detaching from the transverse reinforcement during concrete pouring.
[0056] Example 5
[0057] In the wall panel structure, in order to reduce the area of the reinforcing cage while ensuring structural strength, the reinforcing cage adopts a U-shaped structure, and the blank area in the middle of the U-shaped structure is reinforced: wire mesh 21 is provided inside both sets of composite plates 20, and embedded bodies 23 are pre-embedded on the opposite side of the two sets of wire mesh 21. Connecting cylinders 22 are provided on the embedded bodies 23. The connecting cylinders 22 pass through the wire mesh 21 and are exposed on the outside of the composite plate 20. A tie column 24 is connected between two corresponding connecting cylinders 22. Tie bodies 83 are provided at both ends of the tie column 24 for connecting with the embedded bodies 23.
[0058] An elastic clamping body is installed inside the pre-embedded body 23. The elastic clamping body includes mounting holes distributed on the outside of the pre-embedded body 23. A set screw 231, an elastic element 232 and a clamping head 233 are installed in the mounting holes from the outside to the inside. A tapered guide cone structure 241 is provided at the end of the traction column 24. A clamping ring 242 is provided at the root of the tapered guide cone structure 241. The clamping head 233 and the clamping ring 242 are adapted to constrain the traction column 24.
[0059] In order to facilitate the smooth entry and connection assembly of the tapered guide structure 241, the connecting cylinder 22 is larger at one end and smaller at the other, with the larger end exposed on the outside of the composite plate 20.
[0060] When the tapered guide cone structure 241 at the end of the traction column 24 passes through the connecting cylinder 22 and enters the interior of the embedded body 23, the tapered guide cone structure 241 will first use the tapered guide cone structure 241 to push the clamping head 233 outward and compress the elastic element 232. When the clamping head 233 and the clamping ring are aligned, the elastic element 232 will push the clamping head 233 outward into the clamping ring 242 to complete the connection between the traction column 24 and the corresponding embedded body 23.
[0061] To improve the structural connection strength and stability between structural layers, several equally spaced vertical connecting ribs 25 are provided on the opposite side of each of the two sets of composite plates 20. The vertical connecting ribs 25 have a trapezoidal structure, and the width of the vertical connecting ribs 25 on the side closer to the composite plate 20 is greater than the width on the side farther away from the composite plate 20.
[0062] A prefabricated composite wall panel structure for buildings, the construction method of which includes:
[0063] Step 1, Construction of the central steel reinforcement cage 10
[0064] The installation boundary line of the composite slab 20 and the position boundary line of the central steel cage 10 are marked on the foundation layer by drawing lines, and the central steel cage 10 is obtained by binding the vertical steel bars of the foundation layer.
[0065] Step 2, Construction of a set of composite slabs (20mm).
[0066] Steel structure angle brackets are installed at the installation boundary line of composite slab 20, and the top of the steel structure angle brackets is adjusted to be on the same horizontal plane. Then the transverse steel bars of the middle steel cage 10 are adjusted to ensure that the positions of the transverse steel bars and the connectors 30 correspond.
[0067] First, install the tie column 24 inside the connecting cylinder 22 of one set of composite plates 20. Then, push the composite plate 20 horizontally and longitudinally along the top of the steel structure angle bracket close to the middle steel cage 10 until the upper rotating plate 40 and the lower rotating plate 50 are wrapped around the transverse steel bar, thus completing the connection and fixation of the composite plate 20 and the middle steel cage 10.
[0068] Another set of composite plates 20 is pushed horizontally and longitudinally along the top of the steel structure angle bracket towards the middle of the reinforcing cage 10 until the upper rotating plate 40 and the lower rotating plate 50 are wrapped around the transverse reinforcing bars. At the same time, the pulling body 83 enters the connecting cylinder 22 and is constrained and fixed by the elastic clamping body.
[0069] Step 3, Construction of connector 30
[0070] In step 2, when the connector 30 approaches the transverse reinforcement longitudinally, the lower rotating plate 50 and the upper rotating plate 40 will first contact the transverse reinforcement. Then, as the composite plate 20 continues to approach, the lower rotating plate 50 and the upper rotating plate 40 will rotate around their respective rotation axes. At the same time, the elastic plate 60 will undergo elastic deformation until the free ends of the lower rotating plate 50 and the upper rotating plate 40 approach and abut. At this time, the pulling rope 82 will drive the pulling body 83 and the ratchet 53 to disengage. Then, the spring body 42 will push the socket 43 outward. After the ends of the lower rotating plate 50 and the upper rotating plate 40 complete the contact and abutment, the socket 43 will be inserted into the socket 51 under the action of the spring body 42, and the constraining teeth 431 will constrain and restrict the socket 43 to prevent it from detaching from the transverse reinforcement during concrete pouring.
[0071] Step 4, Install tie column 24
[0072] When the tapered guide cone structure 241 at the end of the traction column 24 passes through the connecting cylinder 22 and enters the interior of the embedded body 23, the tapered guide cone structure 241 will first use the tapered guide cone structure 241 to push the clamping head 233 outward and compress the elastic element 232. When the clamping head 233 and the clamping ring are aligned, the elastic element 232 will push the clamping head 233 outward into the clamping ring 242 to complete the connection between the traction column 24 and the corresponding embedded body 23.
[0073] Step 5: Pour concrete;
[0074] After adjusting the verticality of the two sets of composite slabs 20 to meet the design requirements, the gap between the composite slabs 20 and the foundation structure layer is sealed, and concrete is poured in place in the support area between the two sets of composite slabs 20.

First, install the tie column (24) inside the connecting tube (22) of one of the composite plates (20), then push the composite plate (20) horizontally and longitudinally along the top of the steel structure angle bracket close to the middle steel cage (10) until the upper rotating plate (40) and the lower rotating plate (50) are wrapped around the transverse steel bar, thus completing the connection and fixation of the composite plate (20) and the middle steel cage (10); Another set of composite plates (20) is pushed horizontally and longitudinally along the top of the steel structure angle brackets towards the middle steel cage (10) until the upper rotating plate (40) and the lower rotating plate (50) are wrapped around the transverse steel bars, while the pulling body (83) enters the connecting cylinder (22) and is constrained and fixed by the elastic clamping body. Step 3, Construction of connector (30) In step 2, when the connector (30) approaches the transverse reinforcement in the longitudinal direction, the lower rotating plate (50) and the upper rotating plate (40) will first contact the transverse reinforcement. Then, as the composite plate (20) continues to approach, the lower rotating plate (50) and the upper rotating plate (40) will rotate around their respective rotation axes. At the same time, the elastic plate (60) will undergo elastic deformation until the free ends of the lower rotating plate (50) and the upper rotating plate (40) approach and abut. At this time, the pulling rope (82) will drive the pulling body (83) and the ratchet (53) to disengage. Then, the spring body (42) will push the socket (43) outward. After the lower rotating plate (50) and the upper rotating plate (40) complete the contact abutment, the socket (43) will be inserted into the socket (51) under the action of the spring body (42), and the socket (43) will be constrained and restricted by the restraining teeth (431) to prevent it from detaching from the transverse reinforcement when pouring concrete. Step 4, Install the tie column (24) When the tapered guide cone structure (241) at the end of the traction column (24) passes through the connecting cylinder (22) and enters the interior of the embedded body (23), the tapered guide cone structure (241) will first use the tapered guide cone structure (241) to push the clamping head (233) outward and compress the elastic element (232). When the clamping head (233) and the clamping ring are in the same position, the elastic element (232) will push the clamping head (233) outward into the clamping ring (242) to complete the connection between the traction column (24) and the corresponding embedded body (23). Step 5: Pour concrete; After adjusting the verticality of the two sets of composite slabs (20) to meet the design requirements, the gap between the composite slabs (20) and the foundation structure layer is sealed, and concrete is poured in place in the support area between the two sets of composite slabs (20).
