Description

Technical Field

[0001] This utility model relates to the field of steel structure shear transfer devices, and in particular to a prefabricated steel structure shear transfer device structure. Background Technology

[0002] Prefabricated steel structures, as a new and environmentally friendly building structure, have been widely used in the construction industry in recent years. They transfer a large amount of on-site work from traditional construction methods to factories. By processing and manufacturing building components and accessories in factories, and then transporting them to the construction site, the steel structure is installed on-site using reliable connection methods, which effectively improves construction efficiency and shortens the construction cycle.

[0003] In prefabricated steel structure buildings, the shear transfer device is a key component connecting the bridge deck concrete and the steel beam. Its main function is to form the bridge deck concrete and the steel beam into a whole, ensuring that shear force can be effectively transferred between the two, thereby ensuring the stability and safety of the entire structure. However, the existing shear transfer device structure is not strong enough, and in actual use, it may deform or even break, which will affect the service life of the entire prefabricated steel structure. Therefore, this utility model proposes a prefabricated steel structure shear transfer device structure to solve the above problems. Utility Model Content

[0004] In view of the defects of the existing technology, the purpose of this utility model is to provide a prefabricated steel structure shearing device structure.

[0005] To achieve the above objectives, this utility model provides a prefabricated steel structure shearing device structure, including a steel plate. Several first U-shaped rods are respectively installed on the upper and lower ends of the front side of the steel plate. A second U-shaped rod is installed between two longitudinally arranged first U-shaped rods. Several reinforcing ribs are cross-fixed between two adjacent second U-shaped rods. A reinforcing rod is provided between two longitudinally arranged reinforcing ribs. The reinforcing rod is fixedly installed between two second U-shaped rods. A reinforcing rod is provided at the connection between the first U-shaped rod and the second U-shaped rod. One end of the reinforcing rod is fixedly connected to the first U-shaped rod, and the other end of the reinforcing rod is fixedly connected to the second U-shaped rod.

[0006] Furthermore, a positioning block is fixedly provided at the end of the first U-shaped rod, and a positioning screw hole is provided on the side wall of the positioning block. The positioning block is fixedly connected to the steel plate by positioning bolts.

[0007] Furthermore, a plurality of first reinforcing blocks are fixedly disposed inside the first U-shaped rod, and a second reinforcing block is fixedly disposed on the inner side of the second U-shaped rod.

[0008] Furthermore, the steel plate includes a base layer, and a reinforcing layer is fixedly provided on both sides of the base layer, and an anti-corrosion coating is fixedly provided on the side of the reinforcing layer away from the base layer.

[0009] Furthermore, an H-shaped steel is fixedly installed at the top of each of the first U-shaped bars, and the H-shaped steel is fixedly connected to the crossbar.

[0010] Furthermore, the crossbar is located between the second U-shaped bar and the steel plate, and several third reinforcing blocks are fixedly installed on both sides of the H-shaped steel.

[0011] Furthermore, the first reinforcing block, the third reinforcing block, and the second reinforcing block are all made of stainless steel, and the base layer is made of high-carbon steel.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model enhances the overall structural strength of the shear transfer device by installing the second U-shaped rod between the two first U-shaped rods to form a stable frame structure. The reinforcing rod connects the first U-shaped rod and the second U-shaped rod. When the prefabricated steel structure is subjected to external force, the shear force is transmitted to the shear transfer device through the bridge deck concrete. The shear transfer device distributes the shear force evenly throughout the structure through the first U-shaped rod and the second U-shaped rod. The reinforcing ribs and reinforcing rods enable the shear force to be transmitted and dispersed more effectively inside the shear transfer device. The reinforcing ribs are cross-fixed between adjacent second U-shaped rods, while the reinforcing rods are fixed between two reinforcing ribs, which improves the shear resistance of the shear transfer device.

[0014] 2. This utility model further enhances the local strength of the shearing device by setting a first reinforcing block inside the first U-shaped rod and a second reinforcing block on the inner side of the second U-shaped rod. The H-shaped steel is fixed to the top of each first U-shaped rod and connected to the crossbar. The third reinforcing blocks on both sides of the H-shaped steel further improve the stability of the structure. The steel plate of this utility model firmly fixes the first U-shaped rod to the steel plate by positioning blocks and positioning bolts, which facilitates installation and disassembly.

[0015] 3. The base layer of this utility model is made of high carbon steel, which has high strength and good mechanical properties. The reinforcement layer further enhances the strength of the steel plate, and the anti-corrosion coating effectively prevents the steel plate from corroding in harsh environments, thus extending the service life of the shear.

[0026] Please see Figure 1-5A prefabricated steel structure shearing device includes a steel plate 6. Several first U-shaped rods 4 are installed on the upper and lower ends of the front side of the steel plate 6. Positioning blocks 2 are fixedly installed at the ends of the first U-shaped rods 4. Positioning screw holes 3 are opened on the side walls of the positioning blocks 2. The positioning blocks 2 are fixedly connected to the steel plate 6 by positioning bolts. The steel plate 6, as the core component of the shearing device, securely fixes the first U-shaped rods 4 to the steel plate 6 through the positioning blocks 2 and positioning bolts, facilitating installation and disassembly. A second U-shaped rod 10 is installed between two longitudinally arranged first U-shaped rods 4, forming a stable connection with the first U-shaped rods 4. The frame structure, with reinforcing rods 5 connecting the first U-shaped rods 4 and the second U-shaped rods 10, further enhances the overall structural strength of the shear transfer device. Several reinforcing ribs 7 are cross-fixed between adjacent second U-shaped rods 10, and reinforcing rods 1 are positioned between two longitudinally arranged reinforcing ribs 7. Reinforcing rods 1 are fixed between two second U-shaped rods 10. Reinforcing rods 5 are located at the connection between the first U-shaped rods 4 and the second U-shaped rods 10, with one end fixedly connected to the first U-shaped rod 4 and the other end fixedly connected to the second U-shaped rod 10. When the prefabricated steel structure is subjected to external forces, the shear force is transferred to the shear transfer device through the bridge deck concrete. The shear transfer device distributes the shear force evenly throughout the structure via the first U-shaped rods 4 and the second U-shaped rods 10. The reinforcing ribs 7 and reinforcing rods 1 allow the shear force to be transmitted and dispersed more effectively within the shear transfer device. The reinforcing ribs 7 are cross-fixed between adjacent second U-shaped rods 10, while the reinforcing rods 1 are fixed between two reinforcing ribs 7, improving the shear resistance of the shear transfer device.

[0027] As an improvement to the above technical solution, multiple first reinforcing blocks 11 are fixedly installed inside the first U-shaped rod 4, and second reinforcing blocks 9 are fixedly installed on the inner side of the second U-shaped rod 10. An H-shaped steel 12 is fixedly installed at the top of each first U-shaped rod 4, and the H-shaped steel 12 is fixedly connected to the crossbar 8. The crossbar 8 is located between the second U-shaped rod 10 and the steel plate 6. Several third reinforcing blocks 13 are fixedly installed on both sides of the H-shaped steel 12. The first reinforcing blocks 11, third reinforcing blocks 13, and second reinforcing blocks 9 are all made of stainless steel. The first reinforcing blocks 11 inside the first U-shaped rod 4 and the second reinforcing blocks 9 on the inner side of the second U-shaped rod 10 further enhance the local strength of the shearing device. The H-shaped steel 12 is fixed to the top of each first U-shaped rod 4 and connected to the crossbar 8. The third reinforcing blocks 13 on both sides of the H-shaped steel 12 further improve the stability of the structure.

[0028] As an improvement to the above technical solution, the steel plate 6 includes a base layer 63, with reinforcing layers 62 fixedly installed on both sides of the base layer 63. An anti-corrosion coating 61 is fixedly installed on the side of the reinforcing layer 62 away from the base layer 63. The base layer 63 is made of high-carbon steel, which has high strength and good mechanical properties. The reinforcing layer 62 further enhances the strength of the steel plate. The anti-corrosion coating 61 effectively prevents the steel plate from corroding in harsh environments and extends the service life of the shear.

[0029] The working principle and usage of this utility model:

[0030] In use, the steel plate 6 serves as the core component of the shear transfer device. The first U-shaped rod 4 is firmly fixed to the steel plate 6 by the positioning block 2 and positioning bolts, which facilitates installation and disassembly. The second U-shaped rod 10 is installed between the two first U-shaped rods 4, forming a stable frame structure with the first U-shaped rods 4. The reinforcing rod 5 connects the first U-shaped rods 4 and the second U-shaped rod 10, further enhancing the overall structural strength of the shear transfer device. When the prefabricated steel structure is subjected to external forces, the shear force is transmitted to the shear transfer device through the bridge deck concrete. The shear transfer device evenly distributes the shear force throughout the entire structure via the first U-shaped rod 4 and the second U-shaped rod 10. The reinforcing ribs 7 and reinforcing rods 1 enable the shear force to be transmitted and dispersed more effectively within the shear transfer device. The reinforcing ribs 7 are cross-fixed between adjacent second U-shaped rods 10, while the reinforcing rods 1 are fixed between two reinforcing ribs 7, improving the shear resistance of the shear transfer device. The first reinforcing block 11 inside the first U-shaped rod 4 and the second reinforcing block 9 inside the second U-shaped rod 10 further enhance the local strength of the shear transfer device. The H-shaped steel 12 is fixed to the top of each first U-shaped rod 4 and connected to the crossbar 8. The third reinforcing blocks 13 on both sides of the H-shaped steel 12 further improve the stability of the structure. The base layer 63 is made of high-carbon steel, which has high strength and good mechanical properties. The reinforcing layer 62 further enhances the strength of the steel plate, and the anti-corrosion coating 61 effectively prevents the steel plate from corroding in harsh environments, extending the service life of the shear transfer device.
