Description

Technical Field

[0001] This utility model relates to the field of civil engineering equipment technology, and in particular to a prefabricated steel structure for civil engineering buildings. Background Technology

[0002] In the field of civil engineering, prefabricated steel structures have become an important direction for the transformation and upgrading of the modern construction industry due to their advantages such as high industrial production efficiency, convenient on-site installation, energy saving and environmental protection. These structures are assembled and connected on-site through prefabricated steel components, which significantly shortens the construction cycle and reduces the intensity of on-site work. At the same time, they are in line with the concepts of green building and sustainable development, and have been widely used in residential, commercial buildings, industrial plants and other fields.

[0003] Currently, the connection between vertical beams and horizontal beams in prefabricated steel structures mostly adopts the traditional welding connection method. The welding connection mainly uses high temperature melting to form welds in local areas of the steel, thereby achieving a rigid connection between components. Under certain conditions, this connection method can meet the basic stress requirements of the structure, and the technology is relatively mature, so it is widely used in traditional steel structure construction.

[0004] However, when prefabricated steel structures encounter significant external forces such as earthquakes and strong winds, the joints between vertical and horizontal beams connected by traditional welding methods are prone to deformation due to stress concentration, and may even lead to weld cracking and component separation. This connection failure not only severely affects the integrity and safety of the structure, resulting in functional damage, but also increases the cost of subsequent maintenance and repair, hindering the further promotion and application of prefabricated steel structures in high-load, high-risk environments. Therefore, this paper proposes a prefabricated steel structure for civil engineering to address these issues. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a prefabricated steel structure for civil engineering, which aims to improve the traditional fixed connection between vertical beams and horizontal beams, which is usually achieved by welding. Due to the varying welding skills of different welders, the strength at the joints between the vertical beams and multiple horizontal beams is easily poor. When subjected to large external impact forces, the joints are prone to deformation or even separation.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A prefabricated steel structure for civil engineering includes vertical beams, the outer wall of which is provided with a rectangular array of multiple horizontal beams, and a fixing component and a buffer component are provided between the vertical beams and the horizontal beams.

[0008] The fixing component includes multiple sliders, each slider being fixedly connected to the outer wall of the crossbeam on one side. The outer wall of each slider has a T-shaped structure. A fixing block is fixedly connected to the outer wall of the vertical beam. Multiple sliding grooves arranged in a rectangular array are opened inside the fixing block. Each slider engages with the inner wall of the sliding groove. Multiple hinges arranged in a rectangular array are fixedly connected to the top of the fixing block. A baffle is fixedly connected to the bottom of each hinge. Multiple fixing bolts are provided inside each baffle and extend through to the interior of the slider. A fixing component is provided on one side of each baffle.

[0009] As a further description of the above technical solution:

[0010] The connecting assembly includes multiple connecting frames, and the outer wall of each connecting frame is fixedly connected to one side of the baffle.

[0011] As a further description of the above technical solution:

[0012] Each of the connecting frames has its outer side wall in contact with the inner wall of the crossbeam, and each of the connecting frames has multiple fixing bolts inside, which extend through to the interior of the crossbeam.

[0013] As a further description of the above technical solution:

[0014] The buffer assembly includes multiple viscous dampers, which are distributed in a rectangular array between the vertical beam and the horizontal beam.

[0015] As a further description of the above technical solution:

[0016] The outer wall of the vertical beam is fixedly connected to a plurality of connecting blocks arranged in a rectangular array, and each connecting block is rotatably connected to a transmission block.

[0017] As a further description of the above technical solution:

[0018] Each of the beams has a connecting block 2 fixedly connected to its inner wall, and each connecting block 2 has a transmission block 2 rotatably connected inside it.

[0019] As a further description of the above technical solution:

[0020] Each of the viscous dampers is fixedly connected to a protective cylinder on its outer wall, and the output ends on both sides of each viscous damper are fixedly connected to the outer walls of transmission block one and transmission block two, respectively.

[0021] As a further description of the above technical solution:

[0022] Each of the first and second transmission blocks is fixedly connected to a sliding plate on one side, and the multiple sliding plates are slidably connected to both ends of the inner wall of the protective cylinder.

[0023] This utility model has the following beneficial effects:

[0024] In this invention, the sliding groove engages with the inner wall of the fixed block, and the two pairs of baffles are connected and fixed to the slider by the fixing bolts. Furthermore, the connection component is used to fix the connection between the vertical beam and the horizontal beam, achieving a good fixed connection between the vertical beam and multiple horizontal beams. This solves the problem that the traditional method of fixing the vertical beam and horizontal beam by welding can easily cause deformation or even separation at the joint when subjected to large external impact forces, thus enhancing the stability of the connection between the vertical beam and the horizontal beam.

[0025] In this invention, the vibration force of the vertical beam and the horizontal beam is transmitted to the output end of the viscous damper through transmission block two and transmission block one, thereby reducing the vibration force on the surface of the vertical beam and the horizontal beam. This achieves the effect of positional stability during the use of the steel structure, and solves the problem that fatigue cracks or even deformations easily occur at the connection nodes between the vertical beam and the horizontal beam when the traditional steel structure is subjected to vibrations caused by external environments such as equipment operation or earthquakes. This extends the service life of the components. Attached Figure Description

[0033] 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.

[0034] Reference Figures 1-3 The present invention provides an embodiment of a prefabricated steel structure for civil engineering, including a vertical beam 1, a plurality of horizontal beams 3 arranged in a rectangular array on the outer wall of the vertical beam 1, and a fixing component and a buffer component arranged between the vertical beam 1 and the horizontal beams 3. The fixing component is used to realize the rapid installation and rigid connection between the vertical beam 1 and the horizontal beams 3, and the buffer component is used to absorb the vibration energy generated by the steel structure during equipment operation or earthquakes, effectively preventing fatigue cracks or deformation of the connection nodes due to long-term vibration, and extending the service life of the structure.

[0035] The fixing assembly includes multiple sliders 9, which engage with slide grooves 10 to achieve rapid positioning and installation of the crossbeam 3 and vertical beam 1. The T-shaped structure of the sliders 9 provides a limiting function to prevent the crossbeam 3 from detaching from the vertical beam 1. Each slider 9 is fixedly connected to the outer wall of the crossbeam 3 on one side, and the outer wall of each slider 9 has a T-shaped structure. A fixing block 2 is fixedly connected to the outer wall of the vertical beam 1. The fixing block 2 engages with the sliders 9 to provide load-bearing support and distribute connection stress. The slide groove 10 provides a guiding channel to ensure precise docking of the sliders 9. The fixing block 2 has multiple slide grooves 10 arranged in a rectangular array inside, and each slider 9 engages with the inner wall of the slide groove 10. Multiple hinges 5 arranged in a rectangular array are fixedly connected to the top of the fixing block 2. The hinges 5 engage with the baffle 4 to rotate, achieving rapid opening and closing of the slide groove 10 inlet. The baffle 4 provides a top... The hinge 5 has a limiting function to prevent the slider 9 from moving axially. Each hinge 5 has a baffle 4 fixedly connected to its bottom. Each baffle 4 has multiple fixing bolts 8 inside. The fixing bolts 8 work with the baffle 4 to lock, achieving double fixation of the slider 9. The connecting frame 6 provides lateral support, enhances the torsional rigidity of the crossbeam 3, and extends through to the interior of the slider 9. Each baffle 4 has a fixing component on one side. The connecting component includes multiple connecting frames 6. The connecting frames 6 work with the crossbeam 3 to fit together and assist in positioning. The fixing bolts 7 provide a fastening function, achieving a rigid connection between the connecting frame 6 and the crossbeam 3. The outer wall of each connecting frame 6 is fixedly connected to one side of the baffle 4. The outer wall of each connecting frame 6 fits against the inner wall of the crossbeam 3. Each connecting frame 6 has multiple fixing bolts 7 inside, extending through to the interior of the crossbeam 3.

[0036] Reference Figure 4 and Figure 5The buffer assembly includes multiple viscous dampers 14. The viscous dampers 14 reciprocate in conjunction with the transmission blocks to absorb vibration energy. The protective cylinder 13 provides sealing protection and extends the service life of the viscous dampers 14. The multiple viscous dampers 14 are arranged in a rectangular array between the vertical beam 1 and the horizontal beam 3. Multiple connecting blocks 11 arranged in a rectangular array are fixedly connected to the outer wall of the vertical beam 1. The connecting blocks 11 rotate in conjunction with the transmission blocks 12 to achieve multi-directional transmission of vibration force. The transmission blocks 12 convert the vibration direction, improving energy transmission efficiency. Each connecting block 11 is rotatably connected to a transmission block 12. Each horizontal beam 3 has a connecting block 16 fixedly connected to its inner wall. The second 16 works in conjunction with the second transmission block 15 to perform hinged motion, adapting to different vibration angles. The slide plate reduces frictional resistance, ensuring smooth sliding of the transmission block. Each second 16 is rotatably connected to the second transmission block 15. Each viscous damper 14 has a protective cylinder 13 fixedly connected to its outer wall. The protective cylinder 13 works in conjunction with the slide plate to guide the movement, maintaining the coaxiality of the transmission components. The buffer assembly provides overall shock absorption, improving the seismic performance of the steel structure. The output ends of each viscous damper 14 are fixedly connected to the outer walls of the first transmission block 12 and the second transmission block 15, respectively. Each first transmission block 12 and the second transmission block 15 has a slide plate fixedly connected to one side. Multiple slide plates are slidably connected to both ends of the inner wall of the protective cylinder 13.

[0037] Working principle: During the installation and fixing process between the vertical beam 1 and the horizontal beam 3, the baffle 4 is rotated 90 degrees around the hinge 5, exposing the top space of the slide groove 10. Then, the slider 9 on one side of the horizontal beam 3 is slidably connected to the inner wall of the slide groove 10, so that the slider 9 and the inner wall of the slide groove 10 are engaged. Due to the T-shaped structure of the outer wall of the slider 9, the connection between the fixing block 2 on the outer wall of the horizontal beam 3 and the vertical beam 1 can be fixed. Next, the baffle 4 is rotated 90 degrees in the opposite direction, so that the baffle 4 blocks and fixes the top of the slider 9. At the same time, the connecting frame 6 is moved to the inner wall of the horizontal beam 3, and then the fixing bolts 28 are used. The baffle 4 and the slider 9 are connected and fixed together, and the connecting frame 6 and the crossbeam 3 are connected and fixed together using the fixing bolt 7. This achieves a good fixed connection between the vertical beam 1 and multiple crossbeams 3, which solves the problem that the traditional fixed connection between the vertical beam 1 and the crossbeam 3 is usually fixed by welding. Due to the uneven welding skills of different welders, the strength at the joint between the vertical beam 1 and multiple crossbeams 3 is easily poor. Therefore, when subjected to a large external impact, the joint is easy to deform or even separate. This enhances the stability of the connection between the vertical beam 1 and the crossbeam 3.

[0038] When a steel structure is subjected to vibrations caused by equipment operation or earthquakes, the vibration force drives the connecting block 11 or connecting block 216 to move through the vertical beam 1 or horizontal beam 3. This causes the transmission block 12 or transmission block 215 to slide inside the protective cylinder 13, squeezing the two ends of the viscous damper 14. The elastic characteristics of the viscous damper 14 are used to reduce the vibration force on the surfaces of the vertical beam 1 and horizontal beam 3, achieving the effect of positional stability during the use of the steel structure. This solves the problem that fatigue cracks or even deformation are prone to occur at the connection nodes between the vertical beam 1 and horizontal beam 3 when the traditional steel structure is subjected to vibrations caused by external environments such as equipment operation or earthquakes, thus extending the service life of the components.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
