Description

Technical Field

[0001] The present invention relates to the technical field of concrete wall panels, and particularly to a single-layer concrete interior partition wall panel and a manufacturing method thereof. Background Art

[0002] In high-rise residential building projects, interior partition wall panels are widely used. A large number of interior partition wall panels are required on each floor to divide different rooms and functional areas. In such a building scenario, the problems exposed by traditional interior partition wall panels have seriously affected the building quality, construction efficiency, and living experience.

[0003] On the one hand, in high-rise residential buildings, the wall needs to bear its own weight, the pressure between floors, and possible external forces. The traditional interior partition wall panel made solely of concrete casting has limited self-strength and poor firmness. Over time, under the long-term gravity and the slight vibration of the building itself, problems such as cracks and deformations are likely to occur. In some high-rise residential buildings that have been built for many years, vertical or horizontal cracks in the interior partition wall panels can often be seen, which not only affect the aesthetics but also reduce the sound insulation and heat insulation effects of the wall, and may even affect the stability of the entire building structure.

[0004] To solve the above problems, calcium silicate boards are installed on the outside of the concrete layer for some wall panels. Although the stability is enhanced to a certain extent, the calcium silicate board and the concrete layer are prone to detachment after long-term use. For example, in humid environments such as bathrooms and kitchens in some high-rise residential buildings, due to large humidity changes, the adhesion between the calcium silicate board and the concrete layer decreases, resulting in the calcium silicate board falling off frequently. This not only requires a large amount of manpower and material resources for maintenance but also brings great inconvenience to the lives of residents and increases the use cost.

[0005] On the other hand, in the event of an earthquake or external impact in a high-rise residential building, the requirements for the seismic and anti-impact performance of the wall are extremely high. At present, some interior partition wall panels made of materials such as lightweight concrete on the market, although reducing the weight, still have serious deficiencies in terms of stability, anti-impact performance, and seismic performance. During an earthquake, these interior partition wall panels are easily damaged or even collapse. In some high-rise residential buildings in earthquake-prone areas, the interior partition wall panels have collapsed during earthquakes. This not only poses a direct threat to the lives of the people inside the building but also causes serious damage to the furniture, electrical appliances, and other property inside the room. Even under some minor earthquakes or daily external impacts (such as collisions during the handling of heavy objects), these interior partition wall panels may also crack or break, affecting the normal life of residents and increasing the safety hazards and psychological burdens of residents.

[0006] To solve the above two problems, the present application proposes a single-layer concrete interior partition wall panel and a manufacturing method thereof. Summary of the Invention

[0007] To solve the technical problems existing in the background art, the present invention proposes a single-layer concrete interior partition wall panel.

[0008] A single-layer concrete interior partition wall panel proposed by the present invention includes a wall panel body formed by concrete pouring. Several groups of reinforcement units are arranged inside the wall panel body. The reinforcement unit includes a first skeleton and a second skeleton. The number of the second skeletons is two and they are symmetrically distributed on both sides of the first skeleton. The opposite surfaces of the first skeleton and the second skeleton both have bending parts, and the bending parts on both sides of the first skeleton are symmetrically distributed to form a pouring cavity. The biting strength of the first skeleton, the second skeleton and the concrete is improved through the bending parts and the pouring cavity;

[0009] Specifically, the bending parts of the first skeleton and the second skeleton adopt a symmetric arc-shaped curved surface structure, and the radius of curvature is R = 15 - 25 mm, forming a two-way biting interface with the concrete contact surface. This design increases the contact area between the skeleton and the concrete by 30% - 40% compared with the traditional plane structure, and improves the biting strength through surface friction and mechanical interlocking effect;

[0010] When the bending part is stressed, the arc-shaped curved surface can convert the vertical load into multi-directional shear stress, avoiding stress concentration in a single direction. For example, when the wall panel is subjected to a lateral impact, the continuous arc-shaped structure of the bending part can disperse the local stress to adjacent pouring cavities, reducing the risk of interface peeling;

[0011] The pouring cavity is formed by enclosing symmetric bending parts. After the concrete solidifies in the cavity, a continuous and interlocked "concrete key" is formed. The relative displacement between the skeleton and the concrete is restricted through mechanical anchoring, thereby improving the strength of the wall panel;

[0012] The combination of the bending part and the pouring cavity forms a "skeleton-concrete-skeleton" triangular force transmission system. When the wall panel is bent, the concrete transfers the pressure to the adjacent skeleton through the pouring cavity, while the curved surface biting of the bending part bears the tensile stress, realizing the efficient utilization of material strength;

[0013] Moreover, the symmetrically distributed bending parts generate a reverse torque under the action of shear force. For example, when the wall panel is subjected to a horizontal shear force, the bending parts of the second skeletons on both sides will form a couple effect, converting the shear deformation into a compression constraint between the skeletons, increasing the shear strength by 25% - 30%.

[0014] Furthermore, positioning labels are arranged on the four corner end faces of the wall panel body, enabling workers to quickly and accurately align multiple wall panel bodies during the installation of the wall panel, improving the installation efficiency and accuracy;

[0015] The edge of the wall panel body is provided with a first wire groove and a second wire groove. The first wire groove is centrally arranged, and the second wire grooves are symmetrically distributed on both sides of the first wire groove. Both ends of the first wire groove respectively penetrate the adjacent second wire grooves and are interconnected, providing a special channel for laying the line, avoiding random grooving on the wall panel, facilitating the threading work, and protecting the structural integrity of the wall panel.

[0016] The provision of the first wire trough can meet the needs of lateral wiring, such as circuit guides, and the provision of the second wire trough allows the inner partition wall panels to meet the needs of wiring at different heights, such as air conditioning jacks. After the wiring is completed, the wires connecting the wire troughs can be buried and filled with latex paint or other fillers to keep the wall panel surface smooth without affecting the appearance and use.

[0017] As a further optimized solution of the present invention, the first frame and the second frame are both grid structures, and both have evenly distributed casting gaps thereon, and the casting gaps allow the concrete slurry to penetrate to form anchor points;

[0018] The concrete slurry penetrates the skeleton through the pouring gap to form numerous anchor points. These anchor points tightly connect the skeleton and concrete to form a three-dimensional interlocking structure. Compared with the non-mesh structure, this design greatly improves the interface shear strength and enhances the stability of the wall panels. At the same time, the grid structure restrains the shrinkage and deformation of the concrete. During the concrete solidification process, it reduces cracks caused by shrinkage and improves the quality and durability of the wall panels.

[0019] As a further optimized solution of the present invention, the pouring gap on the first frame is connected with the pouring cavity therein, so that the concrete slurry can flow more smoothly during the pouring process and fill into each space. This not only ensures the fullness of the concrete in the pouring cavity, but also further strengthens the connection between the concrete and the first frame. Moreover, the connected structure enables the concrete to form a more continuous whole. When subjected to external forces, they can work together better and jointly bear the load, thereby improving the overall strength and stability of the wall panels.

[0020] As a further optimized solution of the present invention, the curved portion is a corrugated surface, and after the concrete is poured, concrete anchoring teeth for resisting horizontal shear force are formed at the bottom of the corrugated valley;

[0021] When the wall panel is subjected to horizontal shear force, the concrete anchor teeth can effectively resist the external force and prevent relative slippage between the first frame, the second frame and the concrete. If the external force wants to cause the wall panel to slip, these concrete anchor teeth must be destroyed first. This greatly increases the wall panel's anti-slip ability and improves the stability of the wall panel in actual use, especially under earthquakes or other horizontal external forces, and can better ensure the safety of the building.

[0022] As a further optimized solution of the present invention, the trough bottoms of the corrugations of adjacent two bending parts are arranged in a staggered manner to form a plurality of occluding points, increasing the contact area between the concrete and the corrugated plate by about 15%-20%. This staggered structure enhances the shear strength through a mechanical interlocking effect and decomposes the concentrated stress into multi-directional transmission;

[0023] The staggered arrangement of the trough bottoms of the adjacent bending parts brings multiple advantages. The increased contact area makes the connection between the concrete and the corrugated plate closer. The mechanical interlocking effect enhances the shear strength. When the wall panel is subjected to an external force, the stress can be dispersed to multiple occluding points and transmitted in different directions, avoiding the damage caused by stress concentration. At the same time, this staggered structure changes the water penetration path, forms a discontinuous seepage channel, extends the distance of water penetration, improves the waterproof performance of the wall panel, reduces the damage of the wall panel caused by water penetration, and extends the service life of the wall panel.

[0024] As a further optimized solution of the present invention, partitions located at the openings of the troughs of the bending parts are installed on the opposite surfaces of the second skeleton and the first skeleton, and both ends of the partitions are fixed by fasteners. The number of partitions is multiple and they are evenly distributed along the length direction of the corrugated curved surface of the bending part;

[0025] The multiple evenly distributed partitions can enable the concrete to be better filled and formed in a specific area, enhancing the bonding force between the concrete and the skeleton. At the same time, the partitions are fixed on the second skeleton by fasteners, increasing the stability of the entire reinforcement unit, ensuring that there is no relative displacement between the components during the use of the wall panel, and improving the overall performance of the wall panel;

[0026] The partition is a heat-insulating and sound-insulating board, preferably foam glass, rock wool or other heat-insulating and sound-insulating materials, which can enhance the heat-insulating and sound-insulating performance of the inner partition wall panel.

[0027] As a further optimized solution of the present invention, the fastener includes a fixing column. One end of the fixing column is fixed on the second skeleton and is located at the trough bottom, and the other end of the fixing column extends outwards and passes through the partition and is locked by a nut;

[0028] One end of the fixing column is fixed at the trough bottom of the second skeleton, providing a stable support point for the partition. The nut tightly fixes the partition on the fixing column, preventing the partition from loosening or displacing during the concrete pouring process or during use, ensuring the stability of the structure of the reinforcement unit, and thus enhancing the reliability of the entire wall panel.

[0029] As a further optimized solution of the present invention, one end of the fixing column is fixedly welded to the second skeleton, and a threaded column is installed at the other end of the fixing column. A through hole adapted to the threaded column is opened on the partition, and the threaded column passes through the through hole and is threadedly connected with the nut;

[0030] The fixed column is welded and fixed to the second skeleton, ensuring a firm connection between the fixed column and the second skeleton and making them an integral whole. The threaded column is connected to the fixed column and cooperates with the through hole on the partition board, and is connected by a nut in a threaded manner. This connection method facilitates the installation and disassembly of the partition board. During the construction process, if it is necessary to adjust the position of the partition board or replace the partition board, the operation is relatively convenient, and at the same time, the tightness and stability of the connection are ensured.

[0031] As a further optimized solution of the present invention, the diameter of the through hole is smaller than the diameter of the fixed column. When installing the nut, this size difference enables the partition board to fit more closely on the fixed column, preventing the partition board from shaking or generating gaps on the fixed column. The tight fit not only enhances the connection strength between the partition board and the fixed column, but also avoids the concrete from flowing into the gap between the partition board and the fixed column during the pouring process, ensuring the integrity and stability of the reinforcement unit structure.

[0032] A manufacturing method of a single-layer concrete interior partition board for manufacturing the above interior partition board specifically includes the following steps:

[0033] S1 Frame assembly: Weld the fixed column to the inner side of the second skeleton. Multiple rows of vertically parallel fixed columns are arranged on the inner side surface of each second skeleton. Then weld the threaded column to the free end of the fixed column to ensure that the thread is exposed. Then, put the partition board on the threaded column through the through hole, and thread the nut on the free end of the threaded column and tighten it, so that the partition board is closely attached to the end face of the fixed column to realize the installation and fixation of the partition board;

[0034] In the frame assembly stage, the arrangement of multiple rows of vertically parallel fixed columns provides uniform support for the partition board, ensuring the stability of the partition board installation. Welding the fixed column first and then the threaded column ensures the firmness of their connection. The exposed thread facilitates the subsequent installation of the nut. Putting the partition board on the threaded column and tightening it with the nut can accurately control the position of the partition board, making it closely fit the fixed column, providing a stable structural foundation for the subsequent concrete pouring;

[0035] S2 Reinforcement unit into the mold: Set a liftable fixture above the opening of the mold. The fixture has three clamping ends. Fix the first skeleton and the two second skeletons to the three clamping ends respectively, and then drive the first skeleton and the second skeleton to vertically insert into the designated position in the mold through the fixture;

[0036] The three clamping ends of the liftable fixture can accurately fix the first skeleton and the two second skeletons, ensuring the accuracy of their relative positions when inserted into the mold. The vertical insertion method ensures the verticality of the skeleton in the mold, which is beneficial to the uniformity of the subsequent concrete pouring, enables the reinforcement unit to better combine with the concrete, and improves the overall quality of the wall panel.

[0037] S3 Concrete pouring and forming:

[0038] First, perform the first pouring of concrete. Pour the concrete into the bottom of the inner cavity of the mold, so that the concrete fills all the voids at the lower end of the reinforcement unit, and ensure that the concrete completely wraps the lower end of the reinforcement unit. After the concrete is formed, the fixture releases the clamping of the reinforcement unit and moves upward to reset.

[0039] Secondly, perform the second pouring of concrete. Continue to pour the concrete into the mold, so that the concrete fills all the voids at the upper end of the reinforcement unit, and ensure that the concrete completely wraps the upper end of the reinforcement unit. After the concrete is formed, demold it, and the production of the interior partition board can be completed.

[0040] Pouring the concrete in two times is convenient for stabilizing the reinforcement unit, and can ensure that both the upper and lower ends of the reinforcement unit are fully wrapped, filling all the voids, ensuring the close combination between the concrete and the reinforcement unit, and improving the strength of the wallboard.

[0041] Before the first pouring, it is also necessary to pour and form the first wire groove and the second wire groove. It is necessary to install a core mold adapted to the first wire groove and the second wire groove at the bottom of the inner cavity of the mold, and then pour the concrete into the bottom of the inner cavity of the mold and completely wrap the core mold. After the concrete hardens and forms, the first pouring can be carried out.

[0042] By installing the core mold, the shape of the wire groove can be precisely shaped, ensuring the dimensional accuracy and position accuracy of the wire groove, facilitating the later wire threading work, and at the same time avoiding the damage to the wallboard structure caused by separate grooving.

[0043] The single-layer concrete interior partition board proposed by the present invention has the following beneficial effects:

[0044] (1) By arranging a reinforcement unit inside the interior partition board, using the grid structure of the first skeleton and the second skeleton and having evenly distributed pouring gaps, allowing the concrete slurry to penetrate to form anchoring points, and forming a three-dimensional interlocking structure with the concrete, which is beneficial to improving the interfacial shear strength of the interior partition board, effectively restraining the shrinkage deformation of the concrete, reducing the incidence rate of dry shrinkage cracks during the pouring process, greatly enhancing the stability of the wallboard, thereby reducing the occurrence of problems such as later deformation and detachment, reducing the maintenance cost, and extending the service life of the wallboard.

[0045] (2) Through the tight interlocking of the reinforcement unit and the concrete of the interior partition board, as well as the specially designed bending part and concrete anchoring teeth, when subjected to external impact or earthquake action, the stress can be effectively dispersed. The trough bottoms of the adjacent bending parts are arranged in a staggered manner, forming multiple interlocking points, increasing the contact area between the concrete and the corrugated board, and enhancing the shear strength through the mechanical interlocking effect, decomposing the concentrated stress into multi-directional transmission, so that the wallboard is less likely to be damaged and collapsed when encountering an earthquake or external impact, effectively ensuring the life safety and property safety of the personnel inside the building.

Examples of the embodiments are shown in the drawings, where the same or similar symbols represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary only for explaining the present invention and should not be construed as limiting the present invention.

[0055] In the present invention, unless otherwise clearly defined and limited, the first feature being "on" or "under" the second feature may be that the first and second features are in direct contact, or the first and second features are indirectly in contact through an intermediate medium. Moreover, the first feature being "above", "over" and "on" the second feature may be that the first feature is directly above or obliquely above the second feature, or simply means that the first feature has a higher horizontal height than the second feature.

[0056] In the technical field of concrete wall panels, traditional internal partition wall panels have many problems, such as poor firmness, insufficient stability, poor seismic resistance, unsatisfactory heat and sound insulation effects, and difficulty in threading wires. The single-layer concrete internal partition wall panel and its manufacturing method of the present invention aim to solve these problems, and the specific implementation methods are as follows:

[0057] As Figure 1 and Figure 2 shown, the internal partition wall panel is mainly composed of a wall panel body 1 formed by pouring concrete and several groups of reinforcement units arranged inside it. The reinforcement units are the key parts to improve the performance of the wall panel, including a first skeleton 2 and a second skeleton 3. The two second skeletons 3 are symmetrically distributed on both sides of the first skeleton 2;

[0058] As Figure 3 shown, curved portions 4 are designed on the opposite surfaces of the first skeleton 2 and the second skeleton 3. The curved portions 4 on both sides of the first skeleton 2 are symmetrically distributed and enclose to form a pouring cavity 5;

[0059] The curved portion 4 adopts a symmetric arc-shaped curved surface structure with a curvature radius of R = 15 - 25 mm. This design greatly increases the contact area between the skeleton and the concrete, increasing by 30% - 40% compared with the traditional planar structure. Through the surface friction force and mechanical interlocking effect, the biting strength between the first skeleton 2, the second skeleton 3 and the concrete is improved;

[0060] At the same time, when stressed, the arc-shaped curved surface of the curved portion 4 can convert the vertical load into multi-directional shear stress to avoid stress concentration. For example, when the wall panel is subjected to a lateral impact, the local stress can be dispersed to the adjacent pouring cavity 5 to reduce the risk of interface peeling;

[0061] The concrete solidified in the pouring cavity 5 forms continuous and interlocked "concrete keys", which limit the relative displacement between the skeleton and the concrete through mechanical anchoring action, improving the strength of the wall panel. Moreover, the symmetrically distributed curved portions 4 will generate reverse torque under the action of shear force. For example, when the wall panel is subjected to a horizontal shear force, the curved portions of the two second skeletons 3 on both sides form a couple effect, converting the shear deformation into the compression constraint between the skeletons, increasing the shear strength by 25% - 30%.

[0062] As Figure 3 and Figure 4 shown, both the first skeleton 2 and the second skeleton 3 are grid structures, and pouring gaps 7 are evenly distributed on them. These pouring gaps 7 allow the concrete slurry to penetrate, forming anchoring points after the concrete solidifies, tightly connecting the skeleton and the concrete to form a three-dimensional biting structure. Compared with the non-mesh structure, this design improves the interface shear strength by about 30% - 50%, and at the same time effectively restricts the shrinkage deformation of the concrete, reducing the incidence of dry shrinkage cracks during the pouring process;

[0063] In addition, the pouring gap 7 on the first skeleton 2 communicates with the pouring cavity 5, ensuring that the concrete slurry can flow more smoothly during pouring, filling each space, further strengthening the connection between the concrete and the first skeleton 2, making the concrete form a more continuous whole, jointly bearing the load, and enhancing the overall strength and stability of the wall panel.

[0064] As Figure 4 shown, the bending part 4 is designed as a corrugated curved surface. After the concrete is poured, concrete anchoring teeth for resisting horizontal shear force will be formed at the bottom of the corrugation valley. When the wall panel is subjected to horizontal shear force, these concrete anchoring teeth can effectively prevent relative slippage between the first skeleton 2, the second skeleton 3 and the concrete. To make the wall panel slip under the action of external force, these anchoring teeth must be damaged first, thus greatly enhancing the anti-slip ability of the wall panel and ensuring the safety of the building under the action of earthquake or other horizontal external forces;

[0065] The bottom of the corrugation valley of adjacent two bending parts 4 is arranged in a staggered manner. This design increases the contact area between the concrete and the corrugated plate by about 15%-20%, improves the shear strength through the mechanical interlock effect, decomposes the concentrated stress into multi-directional transmission. At the same time, the staggered corrugations form a discontinuous seepage channel, which can extend the moisture penetration path by about 1.5 times and improve the waterproof performance of the wall panel.

[0066] As Figure 3 and Figure 4 shown, on the opposite surface of the second skeleton 3 and the first skeleton 2, a plurality of partition plates 6 are installed at the opening of the corrugation valley of the bending part 4. These partition plates are evenly distributed along the length direction of the corrugated curved surface of the bending part 4, and both ends are fixed by fasteners;

[0067] The partition plate 6 is preferably made of heat-insulating and sound-insulating materials such as foam glass and rock wool. It can not only enhance the heat-insulating and sound-insulating performance of the inner partition wall panel, but also enable the concrete to better fill and form in a specific area, enhancing the bonding force between the concrete and the skeleton;

[0068] As Figure 5 shown, the fastener includes a fixing column 8, one end of which is welded and fixed at the bottom of the corrugation valley of the second skeleton 3, and the other end extends outward and is provided with a threaded column 9. A through hole 11 adapted to the threaded column 9 is opened on the partition plate 6. After the threaded column 9 passes through the through hole 11, it is locked with a nut 10. The diameter of the through hole 11 is smaller than the diameter of the fixing column 8. In this way, when installing the nut 10, the partition plate 6 can fit more closely on the fixing column 8, preventing the partition plate 6 from shaking or generating gaps, avoiding the concrete from flowing into the gaps, and ensuring the integrity and stability of the reinforcement unit structure.

[0069] As Figure 6 shown, positioning labels 14 are provided at the four corner end faces of the wall panel body 1. When installing the wall panel, workers can quickly and accurately align multiple wall panel bodies 1 according to these positioning labels, improving the installation efficiency and accuracy.

[0070] As Figure 6 shown, a first wire groove 12 and a second wire groove 13 are provided at the edge position of the wall panel body 1. The first wire groove 12 is centrally arranged, and the second wire grooves 13 are symmetrically distributed on both sides of it. The two ends of the first wire groove 12 respectively penetrate through the adjacent second wire grooves 13 and are interconnected. These wire grooves provide a dedicated channel for laying wires, avoiding random grooving on the wall panel, which is convenient for threading and protects the structural integrity of the wall panel;

[0071] Among them, the first wire groove 12 can meet the requirements of horizontal wire arrangement, and the second wire groove 13 can meet the wire arrangement requirements at different heights, such as air conditioner jacks, etc. After the wire arrangement is completed, the wire grooves can be buried and filled with latex paint or other fillers to keep the surface of the wall panel flat, without affecting the appearance and use.

[0072] The manufacturing method of the above-mentioned interior partition wall panel is as follows:

[0073] S1 When manufacturing the interior partition wall panel, first, the frame is assembled;

[0074] On the inner side surface of each second skeleton 3, multiple rows of fixing columns 8 parallel up and down are welded to ensure that the fixing columns 8 are firmly connected to the second skeleton 3;

[0075] Then, a threaded column 9 is welded to the free end of the fixing column 8 to expose the thread for subsequent installation of the nut 10;

[0076] Then, the partition 6 is sleeved on the threaded column 9 through the through hole 11 thereon, and then the nut 10 is threadedly sleeved on the free end of the threaded column 9 and tightened, so that the partition 6 is close to the end face of the fixing column 8, completing the installation and fixation of the partition 6;

[0077] Multiple rows of fixing columns 8 provide uniform and stable support for the partition 6, ensuring the accurate installation position of the partition 6 and providing a reliable structural foundation for subsequent concrete pouring;

[0078] S2 A liftable fixture with three clamping ends is arranged above the opening of the mold. The first skeleton 2 and two second skeletons 3 are respectively fixed on the three clamping ends, and they are vertically inserted into the specified positions in the mold by the fixture. This operation method can accurately control the position and verticality of the skeleton in the mold, ensure the stable position of the reinforcement unit during the concrete pouring process, and is conducive to the uniform combination of the concrete and the reinforcement unit, improving the overall quality of the wall panel;

[0079] S3 Concrete pouring and forming: The concrete pouring is carried out in three stages: before the first pouring, the first pouring, and the second pouring;

[0080] Before the first pouring, first install a mold core adapted to the first wire groove 12 and the second wire groove 13 at the bottom of the inner cavity of the mold, and then pour concrete into the bottom of the inner cavity of the mold to completely wrap the mold core with the concrete. After the concrete hardens and takes shape, conduct the first pouring, pour concrete into the bottom of the inner cavity of the mold to fill all the voids at the lower end of the reinforcement unit, and ensure that the concrete completely wraps the lower end of the reinforcement unit. After this part of the concrete takes shape, the clamp releases the clamping of the reinforcement unit and moves upward to reset. Then conduct the second pouring, continue to pour concrete into the mold to fill all the voids at the upper end of the reinforcement unit, ensure that the concrete completely wraps the upper end of the reinforcement unit, and demold after the concrete is completely formed to obtain the finished inner partition board;

[0081] Pouring concrete in two times can ensure that both the upper and lower ends of the reinforcement unit are fully wrapped, enabling the concrete to be closely combined with the reinforcement unit, improving the strength of the wallboard. By installing the mold core to shape the wire groove, the dimensional accuracy and position accuracy of the wire groove are guaranteed, facilitating the later wiring of wires, and at the same time avoiding the damage to the wallboard structure caused by separate grooving.

[0082] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.

One end of the fixing column (8) is fixed on the second framework (3) and is located at the bottom of the corrugation. The other end of the fixing column (8) extends outwards and penetrates through the partition plate (6) and is locked by a nut (10).

8. A single-layer concrete interior partition wall panel according to claim 7, wherein, One end of the fixing column (8) is fixedly welded to the second framework (3). A threaded column (9) is installed at the other end of the fixing column (8). A through hole (11) adapted to the threaded column (9) is formed on the partition plate (6). The threaded column (9) passes through the through hole (11) and is threadedly connected with the nut (10).

9. A single-layer concrete interior partition wall panel according to claim 8, characterized in that, The diameter of the through hole (11) is smaller than the diameter of the fixing column (8).

10. A manufacturing method of a single-layer concrete interior partition panel, characterized in that, It includes the following steps: S1 Frame assembly: Weld the fixing column (8) to the inner side of the second framework (3). Multiple rows of fixing columns (8) parallel to each other up and down are arranged on the inner side surface of each second framework (3). Then weld the threaded column (9) to the free end of the fixing column (8) to ensure that the thread is exposed. Then sleeved the partition plate (6) on the threaded column (9) through the through hole (11), and threadedly sleeve the nut (10) on the free end of the threaded column (9) and tighten it, so that the partition plate (6) is close to the end face of the fixing column (8), realizing the installation and fixation of the partition plate (6). S2 Reinforcement unit into the mold: A liftable clamp is arranged above the opening of the mold. The clamp has three clamping ends. Fix the first framework (2) and the two second frameworks (3) on the three clamping ends respectively, and then drive the first framework (2) and the second frameworks (3) to vertically insert into the designated position in the mold through the clamp. S3 Concrete pouring and forming: First, conduct the first pouring of concrete. Pour the concrete to the bottom of the inner cavity of the mold, so that the concrete fills all the voids at the lower end of the reinforcement unit and ensures that the concrete completely wraps the lower end of the reinforcement unit. After the concrete is formed, the clamp releases the clamping of the reinforcement unit and moves up and resets. Secondly, carry out the secondary pouring of concrete. Continue to pour concrete into the mold so that the concrete fills all the gaps at the upper end of the reinforcement unit and ensure that the concrete completely wraps the upper end of the reinforcement unit. After the concrete is formed and demolded, the production of the interior partition board can be completed.
