Description

Technical Field

[0001] This utility model relates to the field of building panel structure technology, and in particular to a prefabricated house wall panel structure. Background Technology

[0002] Prefabricated building wall panel structures are wall components used in the field of prefabricated construction. They are prefabricated in factories and quickly assembled on-site, forming the core components of the enclosure and load-bearing structures of prefabricated houses. They are typically made primarily of reinforced concrete, with internal steel reinforcement cages to enhance structural strength. They also include pre-installed connecting components such as sleeves to enable rapid splicing with other walls, floors, or frames.

[0003] Currently, the production and casting process of prefabricated house wall panels presents significant operational complexities. Because the walls must simultaneously meet structural strength and on-site assembly requirements, production involves not only casting reinforcing cages within the concrete to enhance load-bearing capacity but also precisely embedding sleeves for splicing within the wall structure. This process requires the positioning and fixing of the reinforcing cage and the embedding of the sleeves to be carried out simultaneously, demanding extremely high positional accuracy: misalignment of the reinforcing cage leads to uneven wall strength, while deviations in the sleeve position affect the sealing and stability of on-site splicing. To ensure accurate positioning, complex positioning fixtures are often required during production. The reinforcing cage is first fixed, then the angle and depth of the sleeves are adjusted one by one. Furthermore, displacement during concrete pouring must be prevented. The operation is cumbersome and demands high worker skills. Utility Model Content

[0012] Preferably, in any of the above schemes, a plurality of linear arrays of U-shaped connecting steel bars are welded to both the left and right sides of the U-shaped steel frame, and the U-shaped connecting steel bars are perpendicular to the U-shaped steel frame.

[0022] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited thereto.

[0023] like Figures 1 to 5 As shown, a prefabricated house wall panel structure includes a U-shaped steel frame 1 and two symmetrically arranged steel templates 2. The front and rear sides of the U-shaped steel frame 1 are respectively attached to the two steel templates 2. One side of the steel template 2 is rotatably connected to several symmetrically arranged locking bolts 3. The threaded parts of the locking bolts 3 are all threadedly connected to the U-shaped steel frame 1. The inner wall of the U-shaped steel frame 1 is fixedly installed with two symmetrically arranged mounting plates 4 by bolts. A reinforcing cage 5 is welded between the two mounting plates 4. The reinforcing cage 5 is located between the two steel templates 2. The inner wall of the U-shaped steel frame 1 is fixedly installed with several linearly arranged sleeves 6 by bolts. The U-shaped steel frame 1 and the two steel templates 2 are connected by a concrete-poured wall 7. The reinforcing cage 5 and the sleeves 6 are all located inside the wall 7.

[0024] As an optional technical solution of this utility model, the top of the U-shaped steel frame 1 is provided with a number of linear array through holes 8, and the number of through holes 8 corresponds to a number of sleeves 6 respectively. The position of the through holes 8 is consistent with that of the sleeves 6, which facilitates the smooth passage of the connectors and their docking with the sleeves 6 during subsequent splicing, avoids connection difficulties caused by positional deviation, ensures the accuracy and efficiency of the prefabricated wall splicing, and also provides convenience for checking the position of the sleeves 6 before pouring.

[0025] As an optional technical solution of this utility model, several symmetrically arranged threaded holes 9 are provided on both the front and rear sides of the U-shaped steel frame 1. The screws of several locking bolts 3 are threadedly connected to the U-shaped steel frame 1 through the threaded holes 9. The threaded holes 9 provide a stable threaded connection base for the locking bolts 3, so that the locking bolts 3 can tightly fix the steel template 2 on the U-shaped steel frame 1, prevent the steel template 2 from loosening or shifting when pouring concrete, and ensure the forming dimensional accuracy of the wall 7.

[0026] As an optional technical solution of this utility model, each steel template 2 is fixedly connected with several symmetrically arranged positioning pins 13 on the side near the U-shaped steel frame 1. The positioning pins 13 are respectively inserted into the front and rear sides of the U-shaped steel frame 1. The positioning pins 13 can quickly determine their relative position with the U-shaped steel frame 1 when installing the steel template 2, avoid the steel template 2 from being installed crookedly, ensure that the spacing between the two steel templates 2 is uniform, and at the same time assist the locking bolts 3 to quickly align with the threaded holes 9, thereby improving the installation efficiency.

[0027] As an optional technical solution of this utility model, the inner wall of the U-shaped steel frame 1 has two symmetrically arranged embedding grooves 10. Two mounting plates 4 are respectively inserted into the two embedding grooves 10. The depth of the embedding groove 10 is equal to the thickness of the mounting plate 4. The embedding groove 10 effectively limits the mounting plate 4, preventing the mounting plate 4 from shifting during the pouring process, thereby ensuring the accurate position of the reinforcing cage 5 and avoiding uneven strength of the wall 7 due to the displacement of the reinforcing cage 5. At the same time, it makes the mounting plate 4 fit the inner wall of the U-shaped steel frame 1, without affecting the integrity of the concrete pouring.

[0028] As an optional technical solution of this utility model, two corresponding connecting pipes 11 are fixedly connected to the outer surface of each sleeve 6. The side of several connecting pipes 11 away from the sleeve 6 is in contact with the steel template 2. The connecting pipes 11 allow concrete to flow into them during pouring, forming a concrete structure connecting the sleeve 6 and the wall 7. This avoids the sleeve 6 relying solely on its own adhesion to the concrete for fixation, prevents the sleeve 6 from loosening after long-term use, and ensures the structural reliability during splicing.

[0029] As an optional technical solution of this utility model, several linear arrays of U-shaped connecting steel bars 12 are welded to both the left and right sides of the U-shaped steel frame 1. The U-shaped connecting steel bars 12 are perpendicular to the U-shaped steel frame 1. After being poured, the U-shaped connecting steel bars 12 are embedded inside the wall 7. When adjacent walls are spliced, the U-shaped structure can interlock with the concrete or steel bars of the adjacent wall, enhancing the continuity and shear resistance of the overall structure and improving the overall stability of the prefabricated house.

[0030] A prefabricated house wall panel structure, the working principle of which is as follows:

[0031] 1): Insert the mounting plate 4 into the embedded groove 10 of the U-shaped steel frame 1, and fix it with bolts to make the steel cage 5 stably installed on the inner wall of the U-shaped steel frame 1.

[0032] 2): Fix the sleeve 6 to the inner wall of the U-shaped steel frame 1 with bolts, ensuring that the connecting pipe 11 fits the steel template 2 and the through hole 8 corresponds to the sleeve 6.

[0033] 3): Next, position the steel template 2 with the U-shaped steel frame 1 using the positioning pin 13, tighten the locking bolt 3 to fix the steel template 2 through the threaded hole 9, and finally pour concrete to form the wall 7. After the wall 7 is formed, the two steel templates 2 can be disassembled.

[0034] In summary, this prefabricated house wall panel structure involves inserting the mounting plate 4 into the embedding groove 10 of the U-shaped steel frame 1, and securing it with bolts to stably install the reinforcing cage 5 on the inner wall of the U-shaped steel frame 1. Then, the sleeve 6 is fixed to the inner wall of the U-shaped steel frame 1 with bolts, ensuring that the connecting pipe 11 fits snugly against the steel template 2 and that the through hole 8 corresponds to the sleeve 6. Next, the steel template 2 is positioned against the U-shaped steel frame 1 using positioning pins 13, and the locking bolts 3 are tightened to secure the steel template 2 through the threaded holes 9. Finally, concrete is poured to form the wall 7. This operational process utilizes the U-shaped steel frame 1 to provide a unified installation benchmark, the embedding groove 10 to ensure precise positioning of the mounting plate 4 and the reinforcing cage 5, and bolt fixing to prevent displacement. The sleeve 6 is directly fixed to the U-shaped steel frame 1, and the connecting pipe 11 enhances the bond with the concrete. This allows for precise synchronous positioning of the reinforcing cage 5 and the sleeve 6 without the need for complex tooling, simplifying the process. The operation process was streamlined, the skill requirements for workers were reduced, and production efficiency was improved. The reinforcing cage 5 is firmly connected to the U-shaped steel frame 1 through the mounting plate 4, forming an integral load-bearing structure with the concrete during pouring. The sleeve 6 is pre-installed in the wall 7, and the through hole 8 facilitates the insertion of connectors during subsequent splicing. The U-shaped connecting steel bars 12 are welded to both sides of the U-shaped steel frame 1, and after pouring, they combine with the wall 7 to enhance the overall strength. The steel formwork 2 is tightly fixed by locking bolts 3 and positioning pins 13 to ensure the stability of the mold during concrete pouring. In this operation process, the combination of the reinforcing cage 5 and the U-shaped steel frame 1 improves the load-bearing capacity of the wall 7, and the U-shaped connecting steel bars 12 enhance the connection strength between the walls. The precise pre-embedding of the sleeve 6 ensures the sealing and stability of on-site splicing. The overall structural design enables the wall to meet the strength requirements while having reliable splicing performance, adapting to the installation needs of prefabricated buildings.
