Description

Technical Field

[0001] This invention relates to the field of building materials technology, specifically to prefabricated integrated pipeline lightweight concrete non-load-bearing interior partition walls. Background Technology

[0002] In recent years, with the widespread adoption of industrialized construction and green building concepts, prefabricated building technology has developed rapidly, becoming an important trend in the modern construction field. Prefabricated buildings, through factory-prefabricated components and efficient on-site assembly, significantly improve construction efficiency, shorten construction cycles, and effectively reduce resource consumption and environmental pollution during the construction process. In prefabricated building systems, non-load-bearing interior partitions, as key components for space division and functional zoning, play a crucial role in improving overall building quality, efficiency, and sustainability through performance optimization and innovative construction methods. Lightweight concrete materials, due to their excellent physical and mechanical properties such as light weight, high strength, and thermal insulation, have been widely used in the field of non-load-bearing interior partitions.

[0003] However, in existing prefabricated lightweight concrete non-load-bearing interior partition wall technology, the problem that needs to be solved lies in the contradiction between the layout of water and electricity pipelines and the overall performance of the wall. In traditional construction methods, water and electricity pipelines are usually laid on-site by grooving and drilling after the wall is installed. This not only seriously damages the overall structure of the wall and affects its key performance such as sound insulation and fire resistance, but also increases the construction difficulty and cycle, and is prone to quality problems such as wall cracking and pipeline leakage. Although some prefabricated wall panels attempt to embed pipelines in the wall, due to the design limitations of the spliced ​​structure, there is still a risk of cracking at the joints, and the flexibility and integrity of pipeline layout are restricted, making it difficult to meet the strict requirements of prefabricated buildings for efficient, high-quality construction and long-term stability. Therefore, it is necessary to improve it. Summary of the Invention

[0004] The purpose of this invention is to provide a prefabricated, integrated, lightweight concrete non-load-bearing interior partition wall with integrated pipelines, in order to solve the problems in the prior art where the layout of water and electricity pipelines damages the overall structure of the wall, affects the sound insulation and fire resistance performance, and increases the difficulty and time of construction.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a prefabricated, integrated, lightweight concrete non-load-bearing interior partition wall with integrated pipelines, comprising a wall body, wherein the wall body is a single-piece integral structure, forming a single-span interior wall without splicing seams; the interior of the wall body is pre-embedded with bidirectional reinforcing steel wire mesh, pipeline components, junction box components, lifting rings, inclined support sleeves, and corrugated pipes for post-insertion reinforcement; the ends of the pipeline components are connected to the corresponding junction box components.

[0006] Furthermore, the diameter of the reinforcing steel bar in the bidirectional reinforced wire mesh is φ6, the mesh spacing is 600mm×600mm, and the thickness of the concrete protective layer on the outside of the wire mesh is 15mm.

[0007] Furthermore, the lifting ring is a U-shaped double-hook structure, made of Q235B steel bar with a diameter of φ16; the top arc section of the lifting ring is 120mm wide, the height exposed above the top surface of the wall body is 90mm, the length embedded inside is 600mm, the length of the two bottom hooks is 100mm, and the center distance between the hooks is 120mm.

[0008] Furthermore, the number of lifting rings is two, symmetrically arranged on the top surface along the length of the wall body; the corrugated pipes for the rear insert bars are corrugated pipes with a diameter of φ50, and the number is two, symmetrically arranged on the top surface along the length of the wall body.

[0009] Furthermore, the number of the inclined support sleeves is four, arranged symmetrically in two rows on both sides of the wall body; the upper row of inclined support sleeves is 1400mm from the top surface, and the lower row of inclined support sleeves is 550mm from the bottom surface.

[0010] Furthermore, the pipeline assembly is a PVC25 pipeline, and its interface end is flush with the side of the wall body; the box surface of the junction box assembly is flush with the surface of the wall body.

[0011] Furthermore, the wall body is made by mixing and pouring lightweight concrete aggregate and cementitious materials, followed by steam curing or natural curing before demolding.

[0012] Furthermore, the method for manufacturing the wall body includes the following steps:

[0013] S1. Prepare lightweight concrete aggregate, cementitious materials, bidirectional reinforced steel wire mesh, pipeline components, junction box components, lifting rings, inclined support sleeves, and corrugated pipes for post-insertion reinforcement.

[0014] S2. Assemble a 200mm thick special solid plate mold;

[0015] S3. Lay the bidirectional reinforced steel wire mesh in the mold, and then fix the remaining embedded components precisely in the preset positions.

[0016] S4. Pour lightweight concrete into the mold in one go and vibrate it to compact it;

[0017] S5. Steam curing or natural curing of the poured concrete, and demolding after it meets the standards;

[0018] S6. Inspect the dimensions, embedded locations, and appearance quality of the wall structure.

[0019] Furthermore, in step S3, the pre-embedded position deviation between the pipeline assembly and the junction box assembly is no greater than 2mm.

[0020] Furthermore, in step S5, the steam curing temperature is not higher than 60°C and the time is not less than 24 hours, and the natural curing time is not less than 7 days; after step S6, the qualified walls are also numbered and marked, and the marking content includes the installation direction and the location of the embedded parts.

[0021] Compared with existing technologies, the prefabricated integrated pipeline lightweight concrete non-load-bearing interior partition wall provided by this invention integrates water and electricity pipelines, load-bearing reinforcement components, hoisting components, and connecting components into the wall structure through a single integral wall body without splicing seams, and the setting of integrated pre-embedded bidirectional reinforcing steel wire mesh, hoisting rings, inclined support sleeves, corrugated pipes for post-insertion reinforcement, pipeline components, and junction box components. This completely avoids the problems of joint cracking and sound insulation performance degradation of traditional spliced ​​partition walls. At the same time, it realizes dry installation operation with zero grooving and zero drilling on site, thereby greatly improving the integrity and quality stability of the interior partition wall and meeting the scoring requirements of prefabricated component and pipeline integration in the evaluation standard of prefabricated buildings.

[0022] By employing a manufacturing process that involves one-time integral casting in the factory, and by precisely positioning and fixing all pre-embedded components before casting, along with standardized mold assembly, concrete curing, and finished product inspection procedures, the industrialized mass production of interior partition wall products has been achieved. This ensures the positional accuracy of all pre-embedded components and the consistency of product quality, thereby completely eliminating the drawbacks of traditional interior partition walls, such as extensive on-site wet work, long construction cycles, and difficulty in quality control, and significantly improving the efficiency of project construction.

[0030] As attached Figure 1 To be continued Figure 3 As shown:

[0031] Example 1:

[0032] This invention provides a prefabricated, integrated, lightweight concrete non-load-bearing interior partition wall with integrated pipeline system. The wall body 1 is a single, integral structure forming a single-span interior wall without seams. The wall body 1 contains embedded bidirectional reinforcing wire mesh 2, pipeline components, junction box components, lifting rings 3, inclined support sleeves 4, and corrugated pipes 5 for reinforcing bars. The ends of the pipeline components are connected to the corresponding junction box components. The bidirectional reinforcing wire mesh 2 has a steel diameter of φ6 and a mesh spacing of 600mm × 600mm. The concrete protective layer on the outer side of the wire mesh is 15mm thick. The lifting rings 3 are U-shaped double-hook structures made of Q235B steel bars with a diameter of φ16. The top arc section of the lifting rings 3 is 120mm wide, protruding 90mm above the top surface of the wall body 1, and embedded internally. The wall body is 600mm long, with two 100mm long hooks at the bottom and a 120mm center-to-center distance between the hooks. There are two lifting rings 3, which are symmetrically arranged on the top surface along the length of the wall body 1. The corrugated pipes 5 for the rear reinforcing bars are φ50 corrugated pipes, and there are two of them, which are symmetrically arranged on the top surface along the length of the wall body 1. There are four diagonal support sleeves 4, which are symmetrically arranged on both sides of the wall body 1 in two rows. The upper row of diagonal support sleeves 4 is 1400mm from the top surface, and the lower row of diagonal support sleeves 4 is 550mm from the bottom surface. The pipeline assembly is a PVC25 pipeline, and its interface end is flush with the side of the wall body 1. The box surface of the junction box assembly is flush with the surface of the wall body 1. The wall body 1 is made of lightweight concrete aggregate and cementitious material mixed and poured, and then demolded after steam curing or natural curing.

[0033] In use, the wall body 1 serves as the core enclosure and load-bearing base of the prefabricated, integrated, lightweight concrete non-load-bearing interior partition wall. It is a single-panel structure, 200mm thick, cast in one piece at the factory, forming a single-span interior wall without any on-site splicing seams. It not only provides physical partitioning of the building's interior space, offering basic sound insulation, fireproofing, and enclosure performance, but also acts as an integrated load-bearing carrier for all embedded components. It integrates pipelines, junction boxes, hoisting and connecting components within its own structure, fundamentally ensuring the positional accuracy and structural integrity of each embedded component. This avoids the problems of cracking and sound insulation degradation at the joints of traditional spliced ​​wall panels, making it suitable for the dry and rapid construction requirements of prefabricated buildings. The following is a description of a reinforced steel wire mesh (2) serving as the internal structural reinforcement framework of the wall body (1). It utilizes φ6 diameter steel bars arranged orthogonally in both directions with a mesh spacing of 600mm x 600mm, and is protected by a 15mm thick concrete layer. This mesh evenly distributes tensile stress, shear stress, and impact loads on the wall during factory demolding, long-distance transportation, on-site hoisting, and subsequent use. It effectively compensates for the inherent brittleness and low flexural strength of lightweight concrete, significantly improving the wall's crack resistance, impact resistance, and overall stiffness. Simultaneously, it restrains the drying shrinkage and temperature deformation of the concrete, reducing cracks caused by environmental changes during long-term use and ensuring the long-term stability of the wall structure. The following is a description of a hoisting ring (3) for mechanized hoisting of the wall. The specialized load-bearing components are U-shaped double-hook structures made of Q235B hot-rolled steel bars with a diameter of φ16. Two hooks are symmetrically arranged on the top surface along the length of the wall body 1. A 90mm arc segment protruding from the top surface is used for reliable connection with specialized lifting equipment. The 600mm double-hook segment embedded in the wall evenly distributes the lifting load to the entire wall body 1 through the bond force of the concrete, preventing localized stress concentration that could lead to wall damage or lifting ring detachment during lifting. Its standardized dimensions and symmetrical arrangement ensure that the wall remains horizontal during lifting, enabling stable lifting, transportation, and precise positioning of the entire panel, meeting the operational requirements of prefabricated building industrial construction. The inclined support sleeve 4 is for the on-site installation stage of the wall... The wall body 1 has four dedicated connection interfaces for temporary fixation and correction, arranged symmetrically in two rows on both sides. The upper row of sleeves is 1400mm from the top surface of the wall, and the lower row of sleeves is 550mm from the bottom surface of the wall. During on-site construction, the end of the temporary diagonal support can be directly inserted into the corresponding sleeve to quickly complete the temporary support and fixation of the wall. With the help of a 2m straightedge and other correction tools, the verticality and flatness of the wall can be precisely adjusted to ensure the structural stability of the wall before the joint grouting material cures, and to prevent the wall from tilting or shifting. Its preset standardized position and size can realize the quick installation and removal of the diagonal support, which greatly improves the on-site installation efficiency, and completely avoids the damage to the wall structure and internal embedded pipelines caused by drilling holes in the wall surface to install the support.The corrugated pipe 5, used for the post-insertion reinforcement, serves as a reserved channel for the rigid connection between the wall and the upper main structure. Made of φ50 diameter plastic corrugated pipe, two pipes are symmetrically arranged on the top surface along the length of the wall body 1. After on-site installation, the post-insertion reinforcement can be inserted into the connection gap between the wall and the top slab through the corrugated pipe and grout can be injected, achieving a rigid anchorage connection between the wall and the upper floor slab. This significantly improves the integrity and lateral force resistance of the wall and the main structure. Simultaneously, the corrugated pipe effectively protects the post-insertion reinforcement, preventing contamination from concrete or debris, and ensuring the bond strength and connection strength between the post-insertion reinforcement and the grout. Its precise pre-set position corresponds one-to-one with the reserved reinforcement positions in the main structure, eliminating the need for on-site drilling and grooving. This fully complies with the requirements of dry construction methods for prefabricated buildings. The various structures cooperate and work together to achieve the functions of factory prefabrication, integrated construction, mechanized hoisting, and dry installation of the prefabricated interior partition wall.

[0034] Example 2:

[0035] The method for manufacturing the wall body 1 includes the following steps:

[0036] S1. Prepare lightweight concrete aggregate, cementitious materials, and bidirectional reinforced steel wire mesh; 2. Pipeline assembly, junction box assembly, and lifting rings; 3. Diagonal support sleeve; 4. Corrugated pipe for rear reinforcing bars; 5.

[0037] S2. Assemble a 200mm thick special solid plate mold;

[0038] S3. Lay the bidirectional reinforced steel wire mesh 2 in the mold, and then fix the remaining pre-embedded components precisely in the preset positions;

[0039] S4. Pour lightweight concrete into the mold in one go and vibrate it to compact it;

[0040] S5. Steam curing or natural curing of the poured concrete, and demolding after it meets the standards;

[0041] S6. Inspect the dimensions, embedded locations, and appearance quality of the wall body 1.

[0042] In step S3, the deviation between the pre-embedded positions of the pipeline assembly and the junction box assembly is no more than 2mm. In step S5, the steam curing temperature is no higher than 60℃ and the time is no less than 24h, and the natural curing time is no less than 7d. After step S6, the qualified wall is also marked with a number, and the marking content includes the installation direction and the position of the pre-embedded parts.

[0043] S1. Supplement to the material preparation process: Add an inspection process for incoming raw materials, and inspect each batch of lightweight concrete aggregates for particle size, bulk density, and moisture content, cementitious materials for strength grade and stability, as well as the dimensions, materials, and appearance defects of all embedded components; at the same time, conduct concrete trial mixing according to the design mix ratio, and measure the slump, spread, and 28-day compressive strength of the concrete to confirm that the mix ratio meets the design requirements of lightweight and high strength.

[0044] S2. Post-mold assembly supplement: After completing the mold assembly and verifying the mold cavity dimensions (length, width, and thickness deviation ≤ 1mm), thoroughly clean the mold cavity and corners to remove residual concrete residue, oil stains, and other debris. Then, evenly apply water-based release agent, ensuring that there are no missed areas or oil accumulation, to guarantee smooth demolding and no sticking defects on the board surface.

[0045] S3. Supplement to the pre-embedded positioning process: 1. Before laying the bidirectional reinforced steel wire mesh 2, arrange 15mm thick concrete protective layer pads in a quincunx pattern at the bottom of the mold, with a spacing of ≤600mm, to ensure that the concrete protective layer thickness of the steel wire mesh is accurately up to standard; 2. All pre-embedded components are rigidly fixed to the side wall / bottom mold of the mold using special plastic clamps. The connection between the pipeline components and the junction box components is sealed with sealing tape to prevent concrete slurry from entering the pipeline and causing blockage during pouring and vibration; 3. After the pre-embedding is completed, a second check is performed to confirm that the position and elevation of all components are correct before proceeding to the next process.

[0046] S4. Supplement to the pouring and vibration process: Concrete is poured in continuous layers from one end of the mold to the other, with each layer being ≤300mm thick; vibration is performed using an immersion vibrator with a moving distance of ≤400mm, until the concrete surface is covered with slurry and no continuous air bubbles overflow. It is strictly forbidden for the vibrator to touch the embedded components or the inner wall of the mold; after pouring, an aluminum alloy scraper is used to scrape the flat surface according to the elevation, and then a second troweling is performed to ensure that the flatness of the surface meets the requirements for no plastering.

[0047] S5. Supplement to the curing and demolding process: Clarify the demolding strength requirements. Demolding can only be carried out when the concrete compressive strength of the wall body 1 reaches 75% or more of the design strength. When demolding, use special lifting tools to lift the mold smoothly. It is strictly forbidden to pry or smash the mold and the wall. After demolding, immediately grind and repair the burrs, rough edges and missing corners of the wall.

[0048] S6. Finished Product Inspection and Subsequent Supplements: Add a process for handling non-conforming products. Walls that fail inspection should be marked and isolated. Repairable defects should be repaired with special repair materials and re-inspected. Unrepairable defects should be scrapped. For walls that pass inspection, all interfaces of pre-embedded pipelines should be sealed immediately with special plugs to prevent debris and dust from entering the pipelines, and then numbered and marked.

[0049] Application example:

[0050] Prefabricated buildings are currently in a critical stage of large-scale promotion. High-rise residential buildings, as a major application type of prefabricated buildings, have strict requirements on the construction efficiency, quality stability, sound insulation performance, and prefabricated building evaluation indicators for interior partition walls. Traditional masonry interior partition walls suffer from problems such as long construction cycles, large amounts of wet work, serious on-site pollution, and easy cracking later. Conventional spliced ​​lightweight panel partition walls have many joints, poor integrity, and insufficient sound insulation performance. They also require a lot of on-site trenching to lay water and electricity pipelines, which not only damages the integrity of the wall structure but also easily leads to common quality problems such as wall cracking and pipeline leakage. At the same time, they are difficult to meet the scoring requirements for the integration of prefabricated components and pipelines in the prefabricated building evaluation standards. Against this backdrop, the prefabricated pipeline integrated slab lightweight concrete non-load-bearing interior partition wall described in this invention has been applied to a high-rise prefabricated residential building project in the core area of ​​a city. The project consists of multiple high-rise residential buildings, and all standard floors have their interior non-load-bearing interior partition walls constructed using this product. This aims to solve many pain points of traditional interior partition wall construction, while meeting the prefabricated building evaluation requirements of the project and achieving improved quality and efficiency of the project.

[0051] In the early stages of the project, the design firm, in collaboration with the manufacturer, conducted an integrated detailed design based on the architectural, structural, and mechanical and electrical (M&E) construction drawings. This detailed design clarified the dimensions and positioning of each interior partition wall, as well as the locations of water and electricity pipelines and junction boxes. This ensured that all pipelines and junction boxes could be integrated into the wall body 1 at the factory stage, eliminating the need for any on-site grooving work. After the detailed design was completed, the manufacturer prefabricated the wall body 1 according to the design requirements. First, lightweight concrete aggregates, cementitious materials, and various embedded components were prepared according to the specified proportions. Then, a special mold was assembled, and a two-way reinforced steel wire mesh 2 was laid inside the mold as a load-bearing reinforcement skeleton for the wall. Next, the lifting rings 3, the inclined support sleeves 4, the corrugated pipes for the rear reinforcing bars 5, and the pipeline and junction box components were precisely fixed inside the mold according to the detailed design positions. All embedded components were rigidly fixed using special clamps to prevent displacement during the pouring process. After the pre-embedded positioning is completed, lightweight concrete is poured into the mold in one go and fully vibrated to ensure the density of the concrete. After the pouring is completed, the surface of the slab is leveled. Then the mold is sent to the curing area for curing. After the concrete strength reaches the demolding requirements, the mold is demolded. After demolding, the appearance of the wall and the position of the pre-embedded components are inspected. After the inspection is qualified, the wall is numbered and marked, and all pipeline interfaces are sealed, ready for transportation.

[0052] The finished wall panels were transported to the construction site using specialized vehicles. During transport, they were stacked vertically with flexible padding between them to prevent damage to the wall panel itself and its internal embedded components. Once on site, the walls were stacked according to the construction sequence and room zoning. The stacking area was pre-leveled and hardened, with wooden blocks placed at the bottom to prevent moisture damage and deformation. Before on-site construction, the contact surfaces of the floor slab, ground, and structural walls were cleaned to remove dust, debris, and oil. The positioning lines, center lines, and elevation lines of the walls were then marked, and the positions of door openings and pipe connections were verified. After preparation, a specialized hoisting device was connected to the hoisting rings 3 on the top of the wall panel to smoothly lift and slowly lower it to the positioning lines. The wall's position was adjusted to align the embedded pipe interfaces with the main pipeline interfaces on site. After the wall is in place, the ends of the temporary diagonal supports are inserted into the diagonal support sleeves 4 on both sides of the wall body 1 to temporarily fix the wall. Then, tools such as straightedges are used to adjust the verticality and flatness of the wall to ensure that the wall installation accuracy meets the requirements. After the adjustment is completed, the gaps between the wall and the top slab, the ground and the structural wall are filled and sealed. At the same time, corrugated pipes 5 are inserted into the rear reinforcing bars on the top surface of the wall body 1 and grout is injected to achieve a rigid connection between the wall and the upper main structure.

[0053] After the wall installation is completed, the water and electricity pipelines are connected. The main pipelines on site are directly connected to the pre-embedded pipeline components inside the wall body 1. The junction box panel is opened for wiring and testing. After confirming that all lines are unobstructed and the connections are secure, the junction box panel is reset. The entire process does not require any chiseling or breaking of the wall. After the pipeline connection is completed, the wall body 1 is protected. Corner guards are installed at the external corners of the wall to prevent impacts during cross-operations. Protective material is also applied to the wall surface to prevent contamination. After all procedures are completed, relevant units conduct a component-by-component acceptance inspection of the wall project. The inspection includes the wall's installation stability, the quality of joint sealing, the unobstructed flow of pre-embedded pipelines, and the appearance quality of the wall. After passing the inspection, subsequent wall decoration work can proceed. During later operation and maintenance, if water and electricity pipelines need to be inspected, only the corresponding junction box panel needs to be opened for operation, without damaging the wall body 1. If local damage occurs to the wall surface, it can be quickly repaired using special repair materials to restore the integrity and functionality of the wall.

[0054] Working Principle: The wall body 1, as the core load-bearing base of the entire system, adopts a single-piece slab structure cast in one go in the factory, fundamentally eliminating the on-site splicing seams of traditional spliced ​​partition walls. It also provides a unified integrated carrier for all embedded components, solidifying water and electricity pipelines, load-bearing reinforcement components, hoisting components, and connecting components within its own structure. This ensures the relative positional accuracy of each component and the overall structural integrity, while simultaneously undertaking the basic enclosure functions of physical partitioning, sound insulation, and fireproofing of the building's interior space. The bidirectional reinforced steel wire mesh 2 is embedded within the wall body 1 in a bidirectional orthogonal manner, forming a composite load-bearing system with the lightweight concrete, effectively compensating for the inherent structural defects of the lightweight concrete. Despite its brittleness, low flexural strength, and susceptibility to cracking, this design effectively distributes tensile, shear, and impact loads on the wall structure during factory demolding and lifting, long-distance transportation, on-site installation, and subsequent use. It also constrains the drying shrinkage and temperature deformation of the concrete, preventing irregular cracks during long-term use and ensuring the long-term stability and durability of the wall structure. The lifting rings 3 are pre-precisely fixed within the top mold of the wall body 1, forming a unified structure with it. Their U-shaped double-hook structure uses the concrete's gripping force to evenly transfer the lifting load throughout the entire wall body 1, preventing localized stress concentration that could lead to wall damage or ring breakage during lifting. The symmetrical arrangement of the two lifting rings 3 ensures that the wall remains horizontal throughout the lifting process, enabling stable lifting, transportation, and precise positioning of the entire panel, providing a reliable force interface for mechanized construction. The inclined support sleeves 4 are pre-embedded on both sides of the wall body 1, forming standardized temporary support connection interfaces. During on-site installation, there is no need to drill holes in the wall surface; simply insert the end of the temporary inclined support directly into the corresponding inclined support sleeve 4 to quickly complete the temporary fixation of the wall. With the help of correction tools, the verticality and flatness of the wall can be precisely adjusted, ensuring the structural stability of the wall before the joint grout cures, preventing the wall from tilting or shifting, and completely avoiding... To prevent damage to the wall body 1 structure and internal embedded pipelines caused by drilling operations; the corrugated pipe 5 for the post-insertion reinforcement is pre-embedded on the top surface of the wall body 1, forming a reserved channel for the connection between the wall and the upper main structure. After on-site installation, the post-insertion reinforcement can be directly inserted into the connection gap between the wall and the top slab through the corrugated pipe 5 and grouting material can be injected, so that the wall and the upper floor slab form a rigid anchoring connection, which significantly improves the integrity and lateral force resistance of the wall and the main structure. At the same time, the corrugated pipe can effectively protect the post-insertion reinforcement, prevent the post-insertion reinforcement from being contaminated by concrete or debris, and ensure the bond force and connection strength between the post-insertion reinforcement and the grouting material. The connection construction can be completed without on-site drilling and grooving.The pipeline components and junction box components are precisely fixed in the mold according to the design position before the wall body 1 is poured, and are poured and formed simultaneously with the wall body 1. This achieves the integrated integration of water and electricity pipelines with the wall structure. During on-site construction, no grooving work is required on the wall. The main pipeline on site is directly connected to the pipeline components pre-embedded inside the wall body 1, and wiring and debugging can be completed by opening the junction box component panel. This fundamentally eliminates the damage to the wall structure caused by traditional on-site grooving work and the resulting common quality problems such as wall cracking and pipeline leakage. At the same time, in the later operation and maintenance process, if water and electricity pipelines need to be inspected, only the corresponding junction box panel needs to be opened for operation, without damaging the wall body 1, which greatly reduces the difficulty and cost of later operation and maintenance. The above-mentioned structures are interdependent and work together to build a complete prefabricated pipeline integrated panel lightweight concrete non-load-bearing interior partition wall system, realizing the goals of factory prefabrication, integrated construction, mechanized hoisting, and dry installation.
