Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of architectural design, in particular to a green energy-saving prefabricated building wall component. BACKGROUND

[0002] Prefabricated building refers to a building mode in which parts or all components of the building such as walls, floors and stairs are prefabricated in a factory and then transported to the construction site for assembly through reliable connection mode. This mode takes industrialized production as the core and can realize standardized design, large-scale manufacturing and precise installation of components. At present, prefabricated building has been widely used in residential, public building and bridge fields and is an important direction to promote building industrialization and green development.

[0003] In the splicing process of the existing prefabricated building wall component, welding or complex bolt connection is often relied on, which not only has a complicated construction process and a long time consumption, but also easily causes environmental pollution. In addition, the splicing precision is greatly affected by human operation, which may cause problems such as insufficient splicing interface strength and poor pullout and shear resistance. Meanwhile, in the foundation steel bar positioning link, the traditional method requires the construction personnel to observe the steel bar position from below with the help of a reflector. There is a visual blind area in high-altitude operation, which has low positioning precision and poor safety. If there is a position deviation when the steel bar is inserted, it is difficult to automatically correct the deviation, which may affect the connection reliability of the wall and the foundation and the subsequent grouting reinforcement effect. SUMMARY

[0004] In view of the deficiencies of the prior art, the present application provides a green energy-saving prefabricated building wall component, which solves the problems of the existing prefabricated building wall component, such as the dependence on complex connection mode between the components, low positioning precision, complicated construction process and poor safety.

[0005] To achieve the above purpose, the present application realizes the following technical scheme: a green energy-saving prefabricated building wall component, comprising: An outer wall is provided with an inner wall inside, a grouting cavity is formed below the inner wall inside the outer wall, a splicing groove is formed at the position corresponding to the grouting cavity on both sides of the outer wall, a mounting bracket is slidably connected inside the splicing groove, a transmission assembly is installed inside the grouting cavity between the two mounting brackets, and a splicing assembly is installed on the outer wall of the two mounting brackets. A positioning assembly is installed below the outer wall for positioning the insertion of the foundation steel bar.

[0006] Preferably, the transmission assembly comprises transmission rods rotatably connected on both sides of the mounting frame, and a pressing plate rotatably connected between the transmission rods.

[0007] Preferably, the splicing assembly comprises a male plug member fixedly connected to the outer wall of one mounting frame and a female plug member fixedly connected to the outer wall of the other mounting frame, the male plug member is wedge-shaped, the female plug member is internally provided with a wedge-shaped slot matched with the male plug member, and the male plug member and the female plug member are internally provided with mounting holes for bolt fixation.

[0008] Preferably, the positioning assembly comprises a rod sleeve mounted to the inner wall of the outer wall body, the inner wall of the rod sleeve is slidably connected with a limiting block, the bottom end of the limiting block is fixedly connected with a guide rod, the lower portion of the outer wall body is provided with a mounting seat, the guide rod is embedded in the mounting seat, the inner wall of the mounting seat is fixedly connected with a positioning plate, and the positioning plate is internally provided with a positioning hole for the insertion of the foundation steel bar.

[0009] Preferably, the bottom end of the outer wall body is provided with an insertion slot above the positioning hole, and the bottom end of the insertion slot is provided in a trumpet shape.

[0010] Preferably, the inner wall of the positioning plate is internally provided with a plurality of first grouting through grooves, the top portion of the mounting seat and the bottom portion of the outer wall body are both provided with second grouting holes, and the bottom portion of the mounting seat is provided with a grouting hole.

[0011] Preferably, the bottom portion of the outer wall body is provided with a plurality of second grouting through grooves, the front end of the outer wall body is provided with a plurality of first grouting holes, and the second grouting through grooves and the first grouting holes are both in communication with the grouting cavity.

[0012] Working principle: first, the foundation steel bar positioning and insertion work is performed, the outer wall body is hoisted above the foundation steel bar, at this time the mounting seat and the outer wall body are connected only through the guide rod, and the two are in a separated state, the construction personnel can directly observe the position of the steel bar through the positioning hole of the positioning plate, without the need to use a traditional reflector to observe from below, thus simplifying the positioning process, during the steel bar insertion and positioning process, the outer wall body continues to move downward, the guide rod shrinks into the rod sleeve along with the steel bar insertion action, guiding the insertion of the foundation steel bar into the insertion slot, the steel bar is corrected through the trumpet-shaped opening of the insertion slot, and the steel bar insertion and insertion are completed.

[0013] After the reinforcing bar is inserted into the splice groove, it continues to extend into the grouting cavity. The reinforcing bar lifts the pressure plate below, causing the pressure plate to push the slider to slide in the groove. The scissor-type traction plate retracts accordingly, causing the two pressure plates to move towards each other. The transmission rod deflects, thereby driving the mounting frames on both sides to slide in the splicing groove. This causes the male and female splice connectors on the outer wall of one side of the mounting frame to extend outward. When assembling adjacent outer walls, the male splice connector of one outer wall is embedded into the female splice connector of another outer wall. The male splice connector is wedge-shaped and matches the wedge-shaped groove in the female splice connector, realizing the initial splicing of adjacent walls. After the splicing is completed, bolts are inserted into the mounting holes inside the male and female splice connectors to fix them, enhancing the stability of the splicing.

[0014] After the reinforcing bars are inserted, the outer wall and the mounting base are combined. After the wall splicing is completed, concrete is poured for reinforcement. Concrete grout is injected from the grouting hole, first filling the space below the positioning plate, and then entering the area between the mounting base and the bottom of the outer wall through the first grouting channel. At the same time, it is injected into the grouting cavity through the second grouting channel. As the concrete is injected, air and excess grout are first discharged from the second grout outlet and sealed with a rubber stopper. Then, when the grouting cavity is full, it is discharged from the first grout outlet and sealed in the same way. After the concrete fills the grouting cavity, mounting base and other areas, a solid overall structure is formed, which strengthens the wall and ensures the stability and safety of the wall components of the green and energy-saving prefabricated building.

[0015] This invention provides a green and energy-saving prefabricated building wall component. It has the following beneficial effects: 1. This invention utilizes the mechanical linkage design of the transmission components to drive the installation frame to move by the lifting force when the foundation steel bars are inserted. No additional power source is required, which realizes the "passive" splicing between adjacent walls. The scissor-type traction plate ensures that the installation frame moves synchronously, avoids jamming and wear, improves splicing stability and component service life, simplifies the construction process, and conforms to the concept of green building.

[0016] 2. The positioning component of this invention adopts a "separate" design, which decouples the wall hoisting and the rebar positioning. Construction personnel can directly observe the position of the rebar on the ground, avoid blind spots in high-altitude operations, improve positioning efficiency and safety, and the horn-shaped plug slot has a correction function, which can tolerate a certain rebar installation error, reduce construction difficulty, and ensure a reliable connection between the rebar and the wall.

[0017] 3. The layered grouting design utilizes fluid mechanics principles to achieve orderly concrete filling. The low-level grouting holes work in conjunction with the high-level grout outlet holes to effectively expel air and excess grout, preventing voids and cavities. Staged sealing of the grout outlet holes ensures the compactness of each structural layer of concrete, creating an integrated load-bearing system between the wall, foundation, and adjacent walls. This enhances structural stability and seismic performance, reduces concrete waste, and meets energy-saving requirements. Attached Figure Description

Detailed Implementation

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example: Please see the appendix Figure 1 - Appendix Figure 7 This invention provides a green and energy-saving prefabricated building wall component, including an outer wall 1, an inner wall 2 inside the outer wall 1, a grouting cavity 23 corresponding to the lower part of the inner wall 2 inside the outer wall 1, splicing grooves 3 on both sides of the outer wall 1 corresponding to the positions of the grouting cavity 23, mounting brackets 11 slidably connected inside the splicing grooves 3, a transmission component installed between the two mounting brackets 11 corresponding to the inside of the grouting cavity 23, and splicing components installed on the outer walls of the two mounting brackets 11. Specifically, the outer wall 1, as the outer structure of the wall, serves both protective and support functions and is a reinforced concrete skeleton. The inner wall 2 inside it can be made of functional materials such as heat insulation and sound insulation according to the building requirements, forming a composite wall structure. The grouting cavity 23 at the bottom inside the outer wall 1 provides space for concrete pouring. The overall strength of the wall can be enhanced by filling it with concrete later. The splicing grooves 3 on both sides are slidably connected to the mounting frame 11, allowing the mounting frame 11 to move flexibly during the splicing process, laying the foundation for the rapid splicing of adjacent walls.

[0022] The transmission assembly includes transmission rods 12 rotatably connected to both sides of the mounting frame 11. A pressure plate 8 is rotatably connected between the transmission rods 12. The inner walls of the pressure plate 8 are provided with grooves 15 on both sides. A slider 14 is slidably connected inside the grooves 15. A traction plate 13 is rotatably connected to the outer wall of the slider 14. The traction plates 13 are arranged in a scissor-like manner and are rotatably connected to each other. The splicing assembly includes a male connector 9 fixedly connected to the outer wall of one side of the mounting frame 11 and a female connector 10 fixedly connected to the outer wall of the other side of the mounting frame 11. The male connector 9 is wedge-shaped. The female connector 10 has a wedge-shaped groove inside that matches the male connector 9. Both the male connector 9 and the female connector 10 have mounting holes 16 for bolt fixing inside. Specifically, the transmission rod 12 in the transmission assembly is rotatably connected to the mounting frame 11 and the pressure plate 8 at both ends, forming a linkage mechanism. When the pressure plate 8 is subjected to the lifting force of the reinforcing bar below, it will push the mounting frames 11 on both sides to slide outwards towards the splicing groove 3 through the transmission rod 12. The sliding groove 15 on the inner wall of the pressure plate 8 cooperates with the slider 14, so that the scissor-type traction plate 13 retracts synchronously during the sliding process, ensuring the synchronicity of the movement of the mounting frames 11 on both sides. The transmission assembly adopts a mechanical linkage design, using the natural lifting force when the foundation reinforcing bar is inserted to drive the mounting frame to move. No additional power source is required, realizing "passive" splicing. The synchronous retraction mechanism of the scissor-type traction plate can avoid the jamming problem caused by uneven force on the mounting frame, ensuring the stability and reliability of the splicing process, while reducing mechanical wear and extending the service life of the components. The male plug 9 and female plug 10 of the splicing assembly adopt a wedge-shaped fit structure. The wedge-shaped inclined surface of the male plug 9 can guide the adjacent walls to quickly align, and form a mechanical lock after embedding. The mounting hole 16 allows for further fixing with bolts, ensuring the pull-out and shear resistance of the splice interface. The wedge-shaped plug structure enables rapid positioning and initial fixing of adjacent walls, forming a double reinforcement system with bolt connections, which improves splice strength. This not only simplifies the on-site construction process but also avoids the environmental pollution and time consumption caused by traditional welding or complex bolt connections, conforming to the concept of green building. In addition, the standardized male and female plug fittings enable the interchangeability of components, reducing the production and installation costs of prefabricated components.

[0023] The positioning component is installed below the outer wall 1 and is used for the insertion and positioning of the foundation steel bars. The positioning component includes a rod sleeve 24 installed on the inner wall of the outer wall 1. The inner wall of the rod sleeve 24 is slidably connected to a limit block 25. The bottom end of the limit block 25 is fixedly connected to a guide rod 6. The lower part of the outer wall 1 is provided with a mounting base 4. The guide rod 6 is embedded in the interior of the mounting base 4. The inner wall of the mounting base 4 is fixedly connected to a positioning plate 20. The interior of the positioning plate 20 is provided with a positioning hole 18 for the insertion of the foundation steel bars. The bottom end of the outer wall 1 is provided with an insertion groove 21 above the positioning hole 18. The bottom end of the insertion groove 21 is flared. Specifically, the positioning component is slidably connected to the guide rod 6 via the sleeve 24, allowing the outer wall 1 and the mounting base 4 to remain relatively independent during the positioning stage. The positioning hole 18 of the positioning plate 20 precisely matches the foundation reinforcement, allowing construction personnel to directly observe the position of the reinforcement through the positioning hole without the need for tools such as reflectors. The trumpet-shaped bottom end of the insertion slot 21 can automatically correct the inserted reinforcement, ensuring that the reinforcement accurately enters the grouting cavity 23. The "separate" design of the positioning component decouples the wall hoisting and reinforcement positioning process, allowing construction personnel to directly observe the position of the reinforcement from the ground, avoiding blind spots in traditional high-altitude operations and improving positioning accuracy and safety. The correction function of the trumpet-shaped insertion slot can tolerate a certain amount of reinforcement installation error, reducing construction difficulty, while ensuring a reliable connection between the reinforcement and the wall structure, providing a foundation for subsequent grouting reinforcement.

[0024] The positioning plate 20 has several first grouting channels 19 inside. The top two sides of the mounting base 4 and the bottom two sides of the outer wall 1 are provided with second grouting holes 17. The bottom of the mounting base 4 is provided with grouting holes 5. The bottom of the outer wall 1 is provided with several second grouting channels 22. The front end of the outer wall 1 is provided with several first grouting holes 7. The second grouting channels 22 and the first grouting holes 7 are all connected to the grouting cavity 23. Specifically, the first grouting channel 19 and the second grouting channel 22 constitute a concrete flow channel, with the grouting hole 5 serving as the main inlet, allowing concrete slurry to sequentially fill the bottom of the mounting base 4, the top of the positioning plate 20, and the grouting cavity 23. The second grouting outlet hole 17 and the first grouting outlet hole 7 serve as air venting and grout discharge channels for the low and high floors, respectively. Staged sealing ensures the compactness of the concrete filling. The layered grouting design achieves orderly concrete filling through fluid mechanics principles. The coordination between the low-level grouting hole and the high-level grouting outlet hole effectively removes air and excess slurry, preventing the formation of voids or holes. The staged sealing process of the grouting outlet holes ensures the compactness of the concrete in different structural layers, enabling the wall, foundation, and adjacent walls to form an integrated load-bearing system, significantly improving structural stability and seismic performance, while reducing concrete waste and meeting energy-saving design requirements.
