Description

Technical Field

[0001] The utility model relates to the technical field of folding and unfolding, in particular to a civil engineering precast component based on a paper folding structure. Background Technique

[0002] The folding and unfolding structure is a peculiar engineering structure. On the premise of realizing the basic load-bearing function of the structure, it can greatly change its geometric shape to adapt to different working conditions. It is a key technology for large-scale unfolding structures in civil engineering, machinery, aerospace and other fields, and is in the cross-field of mechanisms and structures. Compared with traditional structures, the deployable structure has the advantages of fast construction speed, convenient construction, etc., and is convenient for transportation and storage, and can be used repeatedly, so it is widely used in civil, military, aerospace and other fields.

[0003] The paper folding structure is a branch of the folding and unfolding structure. Paper folding is a traditional art activity that folds a 2D plane into various 3D solid shapes. The paper folding technology inspired by traditional paper folding art is widely used in the engineering field. Its advantages such as portability, deployability, miniaturization and light weight lay the foundation for its application in various fields.

[0004] Similar to paper folding, paper cutting was initially just an art form. In recent years, in-depth research has been carried out and it has been applied to engineering practice. The paper folding structure only has creases and no cut openings. Therefore, paper cutting can simplify the crease design and has greater deployability during the folding and unfolding process; the rigid paper folding does not deform during the folding and unfolding process; the flat-foldable paper folding has good foldability and flexibility.

[0005] The paper folding technology can strengthen the unique mechanical properties of planar materials, such as stretchability and three-dimensional forms of multiple stabilities. These materials and structures can be applied to fields such as spacecraft, buildings, electronic and energy equipment, biology, tissue engineering, biomedical devices, and nano DNA origami. These studies all utilize the complex shapes generated by folding. However, at present, there are few paper folding configurations that can be applied to engineering. To ensure its application in engineering, it is very important to design a single-degree-of-freedom, large deployment ratio, and modular rigid paper folding configuration.

[0023] As shown in the attached Figure 1 to the attached Figure 6As shown in the figure: This embodiment provides a civil engineering precast component based on an origami structure, including: a first precast component 1, with second precast components 2 arranged on both sides of the first precast component 1. Two fixing blocks 3 are fixedly connected to both sides of the first precast component 1. A round rod 4 penetrates through one side of the two fixing blocks 3. Both ends of the round rod 4 are rotatably connected to a linkage plate 5. A clamping block 6 is fixedly connected to one side of the linkage plate 5. A clamping groove 7 adapted to the clamping block 6 is opened on one side of the second precast component 2. An additional part 8 is fixedly connected to one side of the linkage plate 5 and located on the side of the clamping block 6. An adaptation groove 9 adapted to the additional part 8 is opened on one side of the second precast component 2. A fastening groove 10 is opened on one side of the additional part 8. A fastener 11 penetrates through the inner cavity of the fastening groove 10. One side of the fastener 11 extends to the outside of the second precast component 2. Two fixing frames 12 are fixedly connected to both sides of the bottom of the first precast component 1. A linkage block 13 is arranged in the inner cavity of the fixing frame 12. One side of the linkage block 13 is fixedly connected to the second precast component 2.

[0024] Specifically, grooves 14 are opened on both sides of the bottom of the first precast component 1. The fixing blocks 3, the round rod 4, and the linkage plate 5 are all located in the inner cavity of the groove 14.

[0025] In this embodiment: Through the setting of the groove 14, a stable placement space is effectively provided for the fixing blocks 3, the round rod 4, and the linkage plate 5, ensuring that when the linkage plate 5 rotates, unnecessary collisions with the first precast component 1 are avoided, thus guaranteeing the stability of the overall structure and the smoothness of operation.

[0026] Specifically, the inner cavity of the fixing frame 12 gradually narrows from bottom to top.

[0027] In this embodiment: Through the setting of the shape of the fixing frame 12, when the second precast component 2 drives the linkage block 13 to rotate, the linkage block 13 will rotate upward along the inner cavity of the fixing frame 12. The unique shape of the fixing frame 12 makes the contact between the linkage block 13 and the fixing frame 12 more and more tight, thereby realizing the stable positioning of the rotated second precast component 2 and improving the overall stability of the structure.

[0028] Specifically, the shape of the clamping block 6 is cross-shaped.

[0029] In this embodiment: Through the setting of the shape of the clamping block 6, when the clamping block 6 is inserted into the inner cavity of the clamping groove 7, a tenon-mortise connection structure can be quickly and stably formed. And through the setting of the shape of the clamping block 6, seamless docking and tight fitting are realized, thus ensuring the stability and reliability of the connection.

[0030] Specifically, the fastener 11 includes a reinforcing part 111. A reinforcing groove 112 is opened on one side of the reinforcing part 111. An arc angle 113 is arranged on the surface of the reinforcing part 111.

[0031] In this embodiment: through the setting of the fastener 11, under the guidance of the arc angle 113, the reinforcement 111 can smoothly enter the inner cavity of the fixing frame 12, and then, utilizing the unique structure of the reinforcement groove 112, not only the contact area between the reinforcement 111 and the additional component 8 is increased, but also the connection strength and stability between the two are effectively improved, ensuring that the fastener 11 and the additional component 8 are more tightly connected.

[0032] The working principle and use process of this utility model:

[0033] When in use, the linkage plate 5 drives the card block 6 to be stuck into the interior of the card slot 7, building a stable mortise and tenon connection, and the shape of the card block 6 ensures that the card block 6 and the inner wall of the card slot 7 are tightly fitted and stably connected. At the same time, the movement of the linkage plate 5 also pulls the additional part 8 to be embedded in the adapter groove 9, further increasing the integrity of the structure. Subsequently, the fastener 11 penetrates into the inner cavity of the fastening groove 10 from one side of the prefabricated component 2, realizing a firm connection between the prefabricated component 1 and the prefabricated component 2. In the undeployed state, the two are tightly fitted. , together forming a flat plane, which is convenient for storage and transportation. When entering the use stage, by rotating the prefabricated component 2, the prefabricated component 2 drives the linkage plate 5 to rotate at one end of the round rod 4, which not only changes the original spatial layout, but also realizes the transformation from two-dimensional to three-dimensional. In this process, the rotation of the prefabricated component 2 also drives the linkage block 13 to rotate in the same direction, and the connection between the linkage block 13 and the fixing frame 12 is tighter, ensuring that the prefabricated component 2 2 after rotation can be stably positioned, forming a novel structural form that meets the diverse construction needs.
