Description

Technical Field

[0001] This utility model relates to the field of prefabricated building technology, specifically a prefabricated PC board with a reinforced structure. Background Technology

[0002] With the continuous development of the construction industry, traditional on-site casting construction methods have exposed many drawbacks, such as long construction cycles, serious waste of resources, difficulty in construction site management, and significant environmental impact. Prefabricated buildings, with their advantages of fast construction speed, stable and reliable quality, energy saving and environmental protection, and ability to effectively shorten the construction period, have become the development direction of the modern construction industry.

[0003] Prefabricated buildings require the extensive use of various prefabricated components, and prefabricated PC panels, as an important part of this, have been widely used and developed.

[0004] In practical applications, existing ordinary PC board walls often cannot withstand long-term complex mechanical forces due to their inherent strength limitations. Ordinary PC board walls are very likely to crack because they cannot withstand the corresponding stress. Once cracks appear, they will not only damage the integrity of the wall and reduce its load-bearing capacity for the building, but also weaken the wall's ability to resist external environmental erosion, accelerate the aging of the wall material, and thus seriously affect the service life of the building.

[0005] Therefore, this utility model provides an assembled PC board with a reinforced structure to solve the above problems. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] This utility model provides an assembled PC board with a reinforced structure, such as Figs. 1 to 4 As shown, it includes an L-shaped connector 1. A hook-shaped end 101 is provided on one side of the inner top wall of the L-shaped connector 1. A pre-reserved groove 102 is provided between the L-shaped connector 1 and the hook-shaped end 101. An extension is provided at the bottom end of the L-shaped connector 1. A frame 2 is attached to the surface of one side of the extension of the L-shaped connector 1. An abutment surface 201 is provided on one side of the frame 2 near the upper part of the L-shaped connector 1. The abutment surface 201 is attached to one side of the extension of the L-shaped connector 1. A U-shaped frame portion 202 is provided on the lower surface of the frame 2. The inner wall of the frame 202 is a hollow structure. The skeleton 2 is placed on the lower surface of the L-shaped connector 1. The inner wall of the U-shaped frame 202 is movably connected to the arched pressure plate 3. Both ends of the arched pressure plate 3 are provided with spherical ends 301. The outer arc surface of the spherical ends 301 movably abuts against the inner top wall of the U-shaped frame 202. The lower surface of the arched pressure plate 3 is provided with a bottom frame 4 in the middle. Both sides of the lower surface of the bottom frame 4 are provided with bent ends 401. The top of the bent ends 401 abuts against and matches the lower surface of the skeleton 2.

[0025] During the installation and reinforcement of the prefabricated PC panels, the two PC panel bodies 10 are first snapped into the reserved slots 102 to ensure the accuracy of the installation position. At this time, the upper surface of the frame 2 is placed tightly against the bottom surface of the PC panel body 10. Next, the arched pressure plate 3 is fitted into the U-shaped frame 202 of the frame 2. Since the arched pressure plate 3 adopts an elastic structure, as the bottom frame 4 gradually approaches, during the installation process, the specific operation is to connect the threaded rivets 9 through the inner arc surface of the bottom frame 4. When the threaded rivets 9 are continuously tightened, the upward torsion generated by them... The moment will drive the bottom frame 4 to move toward the arched pressure plate 3. As the two continue to approach each other, the spherical ends 301 on both sides of the arched pressure plate 3 will gradually bend and deform upward due to the pressure. At this time, the arched pressure plate 3, which is pushed upward, will tightly abut against the inner top wall of the frame 2 and move synchronously with the frame 2, thereby pushing the entire frame 2 upward toward the PC board body 10. When the frame 2 and the PC board body 10 are close to a certain extent, the frame 2 and the L-shaped connector 1 form a stable clamping structure, thereby providing a strong reinforcement to the PC board body 10.

[0026] This reinforcement method not only enhances the stability of the PC board body 10, effectively preventing displacement and shaking during subsequent use, but also further improves the strength and seismic performance of the entire prefabricated structure. At the same time, it optimizes the tightness of the connection between PC boards, reducing the problem of reduced sound insulation and heat insulation performance caused by gaps.

[0027] A sliding groove hole is provided on one side of the abutment surface 201. A through-plate screw 5 is connected through one side of the abutment surface 201. Both ends of the through-plate screw 5 extend to the outside of the frame 2. Both ends of the through-plate screw 5 are threaded with fastening nuts 6. A pad 7 is provided in the middle of the through-plate screw 5. The lower surface of the pad 7 is placed on the top of the arched pressure plate 3. A spring 8 is sleeved between the pad 7 and the L-shaped connector 1. One end of the spring 8 is sleeved and matched with the through-plate screw 5. The upper surface of the bottom frame 4 is a protruding surface. A hole is provided in the top protruding surface of the bottom frame 4. A threaded rivet 9 is connected through the hole in the inner wall of the bottom frame 4. The upper surface of the threaded rivet 9 extends through the arched pressure plate 3 and is threaded to the surface of the pad 7. There are several threaded rivets 9, which are distributed in a horizontal array on the surface of the pad 7. The PC board body 10 is movably engaged in the reserved groove 102 between the L-shaped connector 1 and the frame 2.

[0028] To achieve a more stable and efficient connection between the two PC board bodies 10, a through-plate screw 5 is installed between the two frames 2. The through-plate screw 5 passes through the two frames 2 to ensure that it plays a supporting and traction role in the connection. On one side of the abutment surface 201, the fastening nut 6 is threadedly connected to the through-plate screw 5. When it is necessary to strengthen the connection effect, the fastening nuts 6 on both sides are rotated with a tool to gradually move them closer to the abutment surface 201. As the fastening nuts 6 are continuously screwed in, a tight clamping state is gradually formed between them and the pad 7. During this process, the spring 8 between the fastening nut 6 and the pad 7 is compressed. The spring 8, with its own elastic potential energy, further enhances the tightness and stability of the clamping, effectively buffering the vibration and displacement caused by external forces.

[0029] Subsequently, the threaded rivet 9 extends outward through the arched pressure plate 3 and is threadedly connected and fixed to the pre-drilled hole on the pad 7. The tightening process of the threaded rivet 9 ensures that the connection strength meets the design requirements. After the threaded rivet 9 is fixed, the entire connection structure forms a whole, and the components work together to improve the connection firmness between the two PC board bodies 10. This connection method not only significantly enhances the tensile and compressive strength of the PC board in the plane, but also effectively resists the shear force in the vertical direction.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
