Description

Technical Field

[0001] The present invention relates to the field of building walls, and in particular to a prefabricated wall, a wall structure, a building wall and a construction method thereof. Background Art

[0002] With the rapid development of the construction industry, prefabricated walls, as a key component of prefabricated buildings, are widely used in modern construction projects due to their advantages such as fast construction speed and controlled quality. Prefabricated walls typically consist of an outer panel, an inner panel, and anchors connecting the two. The cavity between the outer and inner panels is used for pouring concrete to enhance the overall structural strength.

[0003] Currently, common prefabricated wall structures on the market primarily consist of exterior wall panels, insulation layers, and interior wall panels. For example, CN108149819A discloses an integrated laminated exterior wall with a reinforced bottom area. This wall comprises an outer prefabricated wall formwork and an inner cast-in-place structural layer. Adjacent prefabricated panels are connected by tongue-and-groove joints at their upper and lower ends, and anchor rods securely connect the outer prefabricated wall formwork to the inner cast-in-place structural layer. While this structure can reduce on-site wet formwork turnover, it still has certain limitations in the connection between prefabricated panels.

[0004] CN220686404U discloses an assembled modular building wall structure, comprising a concrete wall and prefabricated insulation panels. Multiple anchors are placed across the insulation panels, with limit rods attached to the left and right sides of the anchors to address the issue of the insulation panels shifting within the wall. However, this structure still leaves room for improvement in the connection between the insulation panels and the concrete wall, particularly in terms of ensuring a secure connection while improving construction efficiency.

[0005] CN212802100U proposes a building wall structure with integrated waterproofing and thermal insulation. The inner and middle wall panels are connected by a first anchor to form a casting cavity. The outer wall panels are connected to the middle wall panels by a second anchor, and the insulation layer is secured to the middle wall panels via the second anchor. While this structure allows the insulation layer to be integrated into prefabricated components in the factory, it still has design deficiencies in terms of wall splicing, making it difficult to achieve fast and accurate wall assembly.

[0006] CN220768476U discloses a lightweight insulation board made of a new material. It includes a concrete core, inner panels, and outer panels. Tie bars connect the inner and outer panels, and first and second connecting portions are provided at the edges of the outer panels for connecting adjacent panels. While this design integrates the building's exterior wall, interior wall insulation, and exterior wall insulation into an integrated structure, there is still room for improvement in the integration of the insulation board and concrete.

[0007] CN208251371U describes a prefabricated wall component consisting of a cast-in-place shear wall, insulation panels, and concrete outer panels, connected by supporting and limiting anchors. While this structure achieves support and tensioning, there is still room for improvement in terms of the convenience and accuracy of wall splicing.

[0008] However, the prefabricated wall structure in the prior art still has the following problems:

[0009] 1. The design of the wall splicing structure is not reasonable enough, making it difficult to achieve fast and accurate assembly, affecting construction efficiency and the overall performance of the wall;

[0010] 2. The connection between the outer panel and the insulation board is simple, which may lead to a loose connection between the two and affect the overall performance and service life of the wall;

[0011] 3. The design of the anchors is not optimized enough, making it difficult to simultaneously meet the requirements of connection strength and construction convenience;

[0012] 4. Lack of effective monitoring methods, unable to monitor pressure changes and wall displacement during concrete pouring in real time, making it difficult to ensure pouring quality;

[0013] 5. During the construction process of existing prefabricated walls, defects such as honeycombs, rough surfaces and even voids are prone to occur when pouring concrete, affecting the structural strength and durability.

[0014] Therefore, there is an urgent need for a prefabricated wall with a more reasonable structural design, more convenient splicing, and stronger connection to improve the construction efficiency and quality of prefabricated buildings. Summary of the Invention

[0045] The present application is further described below in conjunction with the accompanying drawings so that those skilled in the art can better understand the present invention and implement it, but the embodiments given are not intended to limit the present invention.

[0046] Example 1

[0047] like Figure 1 As shown, this embodiment provides a prefabricated wall 1, which includes an outer panel, an inner panel, and a plurality of anchors 103. Each anchor 103 is connected to the outer and inner panels at both ends. Because the outer and inner panels are spaced apart, a concrete injection area 109 is formed between them.

[0048] The local areas of two adjacent side walls of the outer plate extend outward to form a first splicing portion a, while the local areas of the other two adjacent side walls of the outer plate are recessed inward to form a second splicing portion a. The local areas of two adjacent side walls of the inner plate extend outward to form a first splicing portion b, while the local areas of the other two adjacent side walls of the inner plate are recessed inward to form a second splicing portion b.

[0049] Specifically, the outer panel body is composed of an outer concrete panel 101 and an insulation panel 102 that are spliced ​​together, the inner panel body is formed by an inner concrete panel 108 , and a concrete injection area 109 is formed between the insulation panel 102 and the inner concrete panel 108 .

[0050] The adjacent first side wall surface and the second side wall surface in the outer concrete slab 101 are both formed with tongue-and-groove connection protrusions a104 protruding outward, and the adjacent third side wall surface and the fourth side wall surface in the outer concrete slab 101 are both formed with tongue-and-groove connection grooves a105 recessed inward.

[0051] The adjacent first side wall surface and the second side wall surface in the insulation board 102 are both formed with tongue-and-groove connection protrusions a104 protruding outward, and the adjacent third side wall surface and the fourth side wall surface in the insulation board 102 are both formed with tongue-and-groove connection grooves a105 recessed inward.

[0052] Furthermore, two dovetail grooves 107 and a dovetail protrusion 106 are formed on the inner end face of the outer concrete slab 101, and a dovetail groove 107 and two dovetail protrusions 106 are formed on the outer end face of the insulation board 102. Through the matching dovetail grooves 107 and dovetail protrusions 106, the spliced ​​outer concrete slab 101 and the insulation board 102 form an outer plate body, the two tongue-and-groove connecting protrusions a104 form a tongue-and-groove connecting protrusion, and the two tongue-and-groove connecting grooves a105 form a tongue-and-groove connecting groove.

[0053] Preferably, the dovetail groove 107 and the dovetail protrusion 106 are at the same height as the outer concrete slab 101 and the insulation board 102. This improves the assembly performance of the outer concrete slab 101 and the insulation board 102 after assembly. Furthermore, this design creates a tight connection between the outer concrete slab 101 and the insulation board 102, preventing relative displacement between the two. Furthermore, the dovetail structure provides a better mechanical locking effect, enhancing the tensile and shear strength of the outer concrete slab 101 and the insulation board 102.

[0054] Furthermore, the adjacent first side wall surface and the second side wall surface in the inner concrete slab 108 are both formed with tongue-and-groove connection protrusions a104 protruding outward, and the adjacent third side wall surface and the fourth side wall surface in the inner concrete slab 108 are both formed with tongue-and-groove connection grooves a105 recessed inward.

[0055] In this embodiment, preferably, both the inner concrete board and the outer concrete board are made by mixing cement lightweight aggregate, fiber reinforcement material, water, admixtures and other raw materials in a certain proportion, and pouring them into special equipment for prefabrication, and the insulation layer adopts extruded board with Class B fireproof performance.

[0056] Specifically, each anchor 103 comprises an end cap, a rod body 1031, and multiple undercuts 1032. The end cap is fixed to the first end of the rod body 1031. The undercuts 1032 are distributed along the longitudinal axis of the rod body 1031 on its outer wall. The second end of the rod body 1031 forms a pointed structure. This design allows the anchor 103 to be firmly anchored in the concrete. The pointed structure facilitates penetration of the anchor 103 into the insulation board 102, while the undercuts 1032 enhance the anchoring force between the anchor 103 and the concrete.

[0057] Preferably, the anchor 103 is made of high-strength engineering plastic and is in the shape of a barbed rod. The barbs are evenly distributed along the rod body 1031, with a height of 8-10 mm and a width of 3-5 mm. The rod body 1031 has a diameter of 12-15 mm and a length determined according to the total thickness of the module. Both ends penetrate into the concrete board by no less than 30 mm.

[0058] In practice, the fabrication process of prefabricated wall 1 begins by connecting the outer concrete slab 101 and the insulation panel 102 via the third and fourth joints. The tip of the anchor 103 is then inserted through the insulation panel 102 into the outer concrete slab 101. A concrete injection area 109 is then formed between the inner panel and the insulation panel 102. After the concrete solidifies, the undercut 1032 of the anchor 103 forms a secure connection with the concrete, tightly connecting the outer and inner panels and the intermediate concrete layer into a single, integrated structure. The prefabricated wall 1 utilizes tongue-and-groove and dovetail connections to enhance the connection strength between its components. The specialized design of the anchor 103 also improves the wall's integrity and resistance to deformation.

[0059] Example 2

[0060] This embodiment provides a prefabricated wall. The difference between this embodiment and the above-mentioned embodiment 1 is that:

[0061] Specifically, the prefabricated wall further includes at least one pressure sensor and at least one displacement sensor.

[0062] Wherein: each pressure sensor is fixed on the inner wall surface of the insulation board or the inner wall surface of the inner layer board body, and is used to monitor the pressure changes of the concrete on the inner wall surface of the insulation board or the inner wall surface of the inner layer board body when pouring concrete. By real-time monitoring of pressure changes, deformation or damage of the insulation board or the inner layer board body due to excessive concrete pressure during the pouring process can be prevented. Each displacement sensor is fixed at the end corner position of the outer wall surface of the insulation board or the end corner position of the outer wall surface of the inner layer board body, and is used to monitor the displacement of the prefabricated wall during the pouring process when pouring concrete. By monitoring the displacement, abnormal deformation of the prefabricated wall during the pouring process can be discovered in time to ensure the dimensional accuracy and structural safety of the prefabricated wall.

[0063] Before pouring concrete, pressure sensors and displacement sensors are installed, and then concrete is poured into the concrete injection area. Through the application of pressure sensors and displacement sensors, intelligent monitoring of the wall pouring process is realized, ensuring the quality and safety of the prefabricated wall.

[0064] Example 3

[0065] This embodiment provides a prefabricated wall, comprising at least two prefabricated walls described in the first or second embodiment.

[0066] The two prefabricated walls are connected in a transverse horizontal manner, wherein the tongue-and-groove connection protrusion a of one prefabricated wall is located in the tongue-and-groove connection groove a of the other prefabricated wall to complete the assembly.

[0067] Example 4

[0068] like Figure 3 As shown, this embodiment provides a wall structure 2 including a plurality of prefabricated walls 201 and a positioning base 202 .

[0069] The structure of the multiple prefabricated walls 201 is similar to the prefabricated walls 201 described in Example 1 or Example 2. Two adjacent prefabricated walls 201 are connected by at least one tongue-and-groove connection protrusion a and at least one tongue-and-groove connection groove a. Each prefabricated wall 201 comprises an outer panel, an inner panel, and multiple anchors. The outer panel is spaced apart from the inner panel, with the ends of the anchors connected to the outer and inner panels, respectively. The outer panel is composed of a spliced ​​outer concrete slab and an insulation panel, with a concrete injection area formed between the insulation panel and the inner panel.

[0070] Specifically, in the wall structure 2, a plurality of prefabricated walls 201 can be connected horizontally and / or vertically to form different wall combinations, including horizontal strip walls, vertical strip walls, or planar walls.

[0071] Horizontal strip walls are formed by connecting multiple prefabricated walls 201 horizontally. During the connection process, the tongue-and-groove protrusions a and grooves a of adjacent prefabricated walls 201 engage with each other, forming a tight tongue-and-groove connection. This horizontal connection method is suitable for scenarios requiring longer walls, such as building perimeter walls or interior partition walls.

[0072] The longitudinal strip wall is formed by connecting multiple prefabricated wall sections 201 vertically. During this vertical connection, the tongue-and-groove joints of the upper and lower prefabricated wall sections 201 also play a role, ensuring the vertical stability and integrity of the wall. This longitudinal connection method is suitable for applications requiring taller walls, such as exterior walls or interior load-bearing walls of high-rise buildings.

[0073] A planar wall is formed by connecting multiple prefabricated walls 201 both horizontally and vertically. This two-dimensional connection creates a larger surface area and greater stability, making it suitable for the rapid construction of large-area walls, such as exterior wall systems for large buildings or large partition walls.

[0074] Whether it's a horizontal strip wall, a vertical strip wall, or a planar wall, they're all fixed to the positioning base 202. The positioning base 202 provides stable support and precise positioning for the wall structure 2. The positioning base 202 is typically made of concrete or steel, and has sufficient strength and rigidity to withstand the weight of the wall and possible external loads.

[0075] The positioning base 202 is provided with grooves or positioning devices that match the shape of the bottom of the prefabricated wall 201, ensuring that the prefabricated wall 201 can be accurately placed in the predetermined position. This positioning method not only improves the accuracy of the wall installation, but also strengthens the connection strength between the wall and the foundation, improving the stability of the overall structure.

[0076] During the installation process, first, the positioning base 202 is fixed on the building foundation, and then the prefabricated walls 201 are placed one by one on the positioning base 202 according to the design requirements, and the tongue-and-groove connection structure between the prefabricated walls 201 is used to achieve a tight connection between adjacent walls.

[0077] This wall structure 2 has several advantages: first, the standardized production and rapid on-site installation of the prefabricated walls 201 greatly improves construction efficiency; second, the tongue-and-groove connection structure of the prefabricated walls 201 ensures a tight connection between the walls, enhancing the stability of the overall structure; third, the use of the positioning base 202 improves the accuracy of wall installation and the connection strength between the wall and the foundation; finally, this wall structure 2 has good thermal insulation properties, which helps to improve the energy efficiency of the building.

[0078] In a preferred embodiment, a sensor interface can also be provided on the positioning base 202 to connect with the pressure sensor and displacement sensor in the prefabricated wall 201 to form a complete monitoring system to monitor the stress state and deformation of the wall structure 2 in real time, thereby improving the safety and reliability of the building.

[0079] Example 5

[0080] like Figure 4 As shown, this embodiment provides a building wall 3, including the wall structure 301 in the fourth embodiment and a concrete layer 302 formed in the wall structure 301 after pouring.

[0081] The composition of the wall structure 301 is the same as that described in Example 3, including multiple prefabricated walls and a positioning base. The multiple prefabricated walls are connected horizontally and / or vertically to form horizontal strip walls, vertical strip walls, or planar walls, and these walls are all fixed to the positioning base.

[0082] Each prefabricated wall structure consists of an outer panel, an inner panel, and multiple anchors. The outer panel is composed of a spliced ​​outer concrete slab and an insulation board, with a concrete injection area formed between the insulation board and the inner panel. The outer and inner panels are connected by anchors, with the ends of the anchors connected to the outer and inner panels respectively.

[0083] In this embodiment, the building wall 3 is constructed on the basis of the wall structure 301, and concrete is poured in the concrete injection area to form a concrete layer 302. The concrete layer 302 fills the space between the insulation board and the inner panel, and is tightly combined with the anchors to form an integral structure.

[0084] During the concrete pouring process, concrete is injected into the concrete injection area through a pre-reserved pouring port. During pouring, the concrete must have moderate fluidity to fully fill the space without exerting excessive pressure on the insulation board and inner panel. After pouring, the concrete solidifies and hardens under natural conditions, forming a solid concrete layer 302.

[0085] The formation of concrete layer 302 gives the entire wall structure 301 greater strength and stability. The combination of concrete and anchors effectively transfers and distributes loads, improving the wall's bearing capacity. Concrete layer 302 also enhances the wall's seismic resistance and durability.

[0086] During the concrete pouring process, pressure sensors and displacement sensors in precast walls play a crucial role. Pressure sensors monitor the pressure changes exerted by concrete on the inner surface of the insulation board or inner layer, ensuring that excessive pressure does not damage the precast wall. Displacement sensors monitor the displacement of the precast wall during pouring, promptly detecting and correcting any misalignment to ensure the accuracy and quality of the final wall.

[0087] The thickness of the concrete layer 302 is typically determined by the distance between the insulation board and the inner panel, typically 50-200 mm, and can be adjusted based on building requirements and structural calculations. The concrete strength grade is typically C25-C40, depending on the building's intended use and load requirements.

[0088] In a preferred embodiment, an appropriate amount of fiber reinforcement material, such as steel fiber, glass fiber, or carbon fiber, may be added to the concrete to further improve the crack resistance and toughness of the concrete layer 302 .

[0089] This building wall 3 combines the efficient installation of prefabricated components with the structural integrity of cast-in-place concrete, ensuring both construction quality and efficiency while also providing excellent thermal insulation. Furthermore, real-time sensor monitoring ensures the safety and reliability of the wall structure 301, making it an ideal solution for modern building walls 3.

[0090] Example 6

[0091] In this embodiment, a construction method is provided, which includes the following steps:

[0092] S100, after comprehensive mapping of the construction site, the piling operation is completed.

[0093] Specifically, a comprehensive survey of the construction site was conducted to generate a three-dimensional terrain model and determine the site's coordinates and elevation. High-precision laser scanners and drone aerial photography were used during the surveying process to ensure the accuracy and comprehensiveness of the surveying data. Once the surveying was complete, piling equipment was used for the operation. GPS and tilt sensors on the piles monitored the verticality and depth of the piles in real time. The piling equipment used a hydraulic pile driver, capable of precisely positioning itself according to the preset pile locations in the three-dimensional terrain model. The GPS system achieved centimeter-level accuracy, and the tilt sensors detected deviations in the pile verticality, automatically triggering an alarm and adjusting the piles if the deviation exceeded 0.5 degrees.

[0094] S200: Fix multiple prefabricated walls on a positioning base according to a required pattern to form a wall structure.

[0095] Specifically, each prefabricated wall is placed on a positioning base using lifting equipment. The lifting equipment includes a crane, an intelligent positioning device, and a modular fixture. The intelligent positioning device includes high-precision sensors and an image recognition system. During the lifting of the prefabricated wall, the distance between the prefabricated wall and the target installation location is measured in real time, the prefabricated wall's tilt angle is monitored, and the spatial position of the prefabricated wall is determined. The image recognition system identifies characteristic markings on the prefabricated wall and the positioning base to determine the prefabricated wall's orientation. The high-precision sensors include a laser rangefinder and a gyroscope, achieving a distance measurement accuracy of ±2mm and an angle measurement accuracy of ±0.1 degrees. RFID tags are pre-installed on the prefabricated wall to facilitate system identification and positioning. After lifting is completed, a connecting device is used to connect adjacent prefabricated walls and the prefabricated wall to the positioning base to form the wall structure. The connecting device includes high-strength bolt connectors and dedicated connection grooves to ensure a secure and reliable connection.

[0096] S300, pouring concrete into the concrete injection area of ​​the wall structure. After pouring, smoothing the top surface of the concrete to form a building wall. During pouring, monitoring and uploading status information of the wall structure.

[0097] Specifically, the concrete injection area is first cleaned to ensure it is free of debris and accumulated water. Dust and debris are removed using a high-pressure air gun, and any accumulated water is removed using a water suction device. After cleaning, concrete is poured into the area using a layered pouring and vibration method. Pressure sensors and displacement sensors monitor the pressure changes of the concrete on the inner wall of the insulation board or inner layer of the board, as well as the displacement of the precast wall during pouring. C30 grade concrete is used, with each layer poured to a thickness of no more than 30 cm and a vibration time of 30-60 seconds per point. Pressure sensors are installed at key locations within the precast wall to monitor the pressure applied to the wall in real time during pouring. When the pressure exceeds a set threshold, the system automatically adjusts the pouring speed. Displacement sensors monitor the displacement of the precast wall with an accuracy of 0.1 mm, ensuring the wall remains stable during pouring. After pouring, a mechanical trowel is used to smooth the top surface of the concrete to ensure the surface flatness meets the design requirements.

[0098] S400, installation of water and electricity line components, as well as decoration and waterproofing.

[0099] Specifically, the installation of water and electricity wiring components was carried out according to a pre-designed pipeline diagram, using pre-buried piping to ensure a rational and aesthetically pleasing layout. The decorative treatment included wall plastering, primer, and topcoat, using environmentally friendly materials to ensure high indoor air quality. Waterproofing, primarily targeting humid areas like bathrooms and kitchens, involved applying multiple layers of flexible waterproof coating with a minimum thickness of 1.5mm. A 24-hour water-tightness test was also performed to ensure waterproofing effectiveness.

[0100] For the installation of water and electricity lines, including prefabricated wiring harnesses, the wires are cut, stripped, and wired to specifications and lengths according to specific circuit requirements. They are then arranged and secured with insulating tubing and binding tape to form standardized wiring harness assemblies. Water pipe sections are also prefabricated. Cutting, beveling, and connector installation are completed in the factory according to different pipe diameters and connection requirements to form standardized water pipe section assemblies. These standardized assemblies simply connect to the pre-set pipe grooves within the module at the construction site using quick connectors (such as bayonet connectors and plug-in connectors), greatly improving installation efficiency and quality.

[0101] Modular equipment installation involves integrating the toilet, washbasin, and shower into a modular unit, which is assembled and commissioned in the factory. At the construction site, the modular unit is directly connected to the embedded components within the module and connected to the water and electricity lines via quick connectors, enabling rapid installation. This approach reduces the complexity and workload of on-site construction and improves the accuracy and reliability of equipment installation.

[0102] Prefabricated exterior wall panels include the design and production of various types of prefabricated exterior wall panels, including stone-like panels, wood-grain panels, and metallic-textured panels. These panels are made from lightweight, high-strength materials such as aluminum veneer and fiber cement board, and utilize specialized surface treatments (such as fluorocarbon spraying and thermal transfer) to achieve diverse finishes. Panel dimensions are customized to the module's exterior wall dimensions, ensuring a perfect match. During installation, the panels are quickly secured to the module's exterior wall using hooks or slots. These hooks or slots are made from high-strength metal and offer excellent load-bearing capacity and durability. Before installing the panels, the panels are first mounted on the module's exterior wall. The hooks or slots are then precisely aligned with the mounting brackets, allowing for simple installation. These prefabricated exterior wall panels are not only easy to install but also easy to replace, allowing for partial or complete replacement based on building needs and design changes.

[0103] Roof decoration and waterproofing include the use of new metal or resin tiles. These tiles offer advantages such as light weight, high strength, excellent waterproofing, and a variety of colors. Before roof construction, the base layer is treated to ensure it is flat and dry. Waterproofing membrane or coating is then applied according to design requirements to form a reliable waterproof layer. Once the waterproof layer is complete, the roof tiles are laid. Roof tiles are secured with dedicated fasteners, which are bolted or welded to the base layer to ensure a secure and reliable fit. Furthermore, special treatment is applied to the eaves and ridges of the roof, using sealant and metal flashing for sealing and waterproofing to prevent rainwater seepage.

[0104] Through the above construction method, it is possible to achieve efficient, accurate and safe construction, improve construction quality and efficiency, reduce human errors, and ensure the safety and controllability of the construction process through a real-time monitoring system.

[0105] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
