Description

Technical Field

[0001] The present invention relates to the technical field of steel structures, in particular to a quick-installable spliced steel structure. Background Art

[0002] Quick-install spliced steel structures are composed of prefabricated components, which can be quickly assembled through efficient connection methods. They can be flexibly spliced, with fast construction and low cost. They are widely used in temporary or small buildings.

[0003] However, there are still some problems with the existing connectable steel structures: First, during the rapid construction of temporary factories, the assembly of pillars often requires a lot of manual auxiliary operations. After the two steel structures are close to each other in the vertical position, the position must be precisely adjusted to complete the assembly. Due to the heavy weight and different shapes of the steel structures themselves, manual manipulation is not only laborious, but also the operation process is extremely cumbersome. Construction workers need to spend a lot of time and energy to ensure that the assembled parts are accurately stuck together, which not only increases labor costs, but also greatly reduces construction efficiency. Once the position adjustment deviates, the operation may need to be repeated, further delaying the construction period.

[0004] Secondly, in order to ensure the beauty and safety of the building, existing steel structures often arrange the lines inside the structure. However, the current splicing method cannot perform wiring operations before assembly. The wiring can only be unified after the steel structure is completely assembled. This process is not only cumbersome, but also extremely difficult to operate. The internal space of the assembled steel structure is limited. The operator is wiring in a narrow space, and his movements are restricted, making it difficult to perform operations. At the same time, since the steel structure has been fixed, the laying path of the line is also restricted, which increases the complexity of the wiring. Moreover, if the line needs to be inspected or replaced later, the difficulty of operation will be greatly increased due to the closed nature of the steel structure.

[0005] Secondly, in temporary or small buildings, although assembled steel structures themselves have certain advantages, due to their large size, in order to ensure structural strength, it is usually necessary to add reinforcing ribs on their surface. However, there are obvious disadvantages in installing reinforcing ribs before assembly. On the one hand, due to the large size and complex shape of the steel structure, when installing reinforcing ribs on its surface, construction workers need to operate at different angles and positions, which not only consumes physical strength, but also makes it difficult to ensure the accuracy and quality of the installation. On the other hand, steel structures with reinforcing ribs installed cannot be stacked together tightly for transportation, which greatly increases transportation costs and space occupancy. For example, a transport vehicle can originally carry multiple steel structures without reinforcing ribs installed, but after installation, it may only be able to load a small amount, resulting in a significant reduction in transportation efficiency.

[0006] In addition, due to accuracy issues or changes in site requirements, the reinforcing ribs installed in advance often cannot meet the actual needs of the site. During the actual construction process, the design may not be consistent with the site conditions. At this time, the position of the reinforcing ribs needs to be adjusted. The reinforcing ribs are usually fixed to the surface of the steel structure by welding. Removing and replacing welded reinforcing ribs is a complicated and time-consuming task. The removal process may cause damage to the steel structure itself, affecting its overall strength and stability. Replacing new reinforcing ribs requires re-welding and re-installation, which increases the workload and cost of construction.

[0007] To this end, the present invention proposes a quick-install splicing steel structure. Summary of the Invention

[0012] Preferably, the side of the annular interface away from the sealing ring gradually shrinks, and the side of the annular socket close to the steel body gradually expands. The shape of the annular socket is adapted to the shape of the annular interface. The interior of the sealing ring is set to be hollow, and the cross-section of the sealing ring is set to be stepped, and the step width gradually decreases from bottom to top.

[0013] Preferably, the annular interface and the annular socket are both configured to be conical, and the annular socket is configured to be hollow.

[0014] Preferably, the wiring path is configured as a hexagonal path, and the edges thereof are all rounded.

[0016] Preferably, an adjustable rib assembly is provided on the outside of the steel body, and the adjustable rib assembly includes four limit rail blocks, and the limit rail blocks are all arranged in a rectangular and equidistant manner and installed on the outer surface of the steel body, and the outer surfaces of the limit rail blocks are slidably connected to sliding slot blocks, and the outer surfaces of the sliding slot blocks are arranged in a rectangular and equidistant manner and are rotatably connected to the first rib plate, and the outer surface of the steel body is arranged in a rectangular and equidistant manner and is rotatably connected to a plurality of second rib plates, and the bottoms of the second rib plates are rotatably connected to the tops of the first rib plates, and the bottoms of the sliding slot blocks are arranged in a rectangular and equidistant manner and are fixedly connected to support plates, and the bottoms of each of the limit rail blocks are linearly and equidistantly arranged and symmetrically provided with first threaded holes, and the bottoms of each of the support plates are provided with second threaded holes, and bolts are installed in the second threaded holes.

[0017] Preferably, the bolt is threadedly connected to the inside of the first threaded hole, and the side of the support plate away from the bolt is set to be trapezoidal.

[0018] Preferably, a plurality of lifting rings are installed on the outer surface of the sliding slot block, and the lifting rings can change the position of the sliding slot block on the steel body through the operation of an external lifting device.

[0019] Preferably, a deformation groove that allows the sealing ring to deform is provided on the surface of the annular socket.

[0020] Compared with the prior art, the beneficial effects of the present invention are: 1. Through the mutual cooperation of the tapered annular interface and the annular socket, a self-centering function will be generated when hoisting the steel body, which means that the construction workers only need to roughly align the two steel bodies, and there is no need to perform precise position adjustments like the traditional splicing method, which greatly reduces manual intervention. Therefore, with this self-centering design, only a small amount of manpower is required for simple preliminary alignment to quickly enter the splicing process. At the same time, in the process of cooperation between the annular interface and the annular socket, the two self-locking blocks will also conflict and collide with each other, and get stuck with each other, further improving the structural stability of the steel body and making the spliced steel structure more firm and reliable.

[0021] Therefore, in the rapid construction of temporary factories, by splicing two vertical steel bodies, the construction efficiency can be significantly improved, thereby greatly shortening the construction period. Compared with existing technologies, this design not only reduces the complexity and labor intensity of manual operations, but also improves the accuracy and stability of splicing.

[0022] Among them: through the setting of the wiring path, not only can the line layout be convenient, but the hexagonal wiring path has good anti-deformation function, which enhances the overall structural stability of the steel body.

[0023] Among them: the stepped sealing ring can improve the sealing effect when the two steel bodies are assembled. It is squeezed and deformed into a multi-layer structure, which increases friction and sealing.

[0024] Among them: the step width of the sealing ring gradually decreases from bottom to top, thereby ensuring that the top sealing ring is deformed first, making it deform stably and avoiding being squeezed into an irregular shape.

[0025] Among them: through the arrangement of the moving block and the driving member, the moving block can be opened horizontally, which is convenient for construction workers to lay wires in the wiring path and simplifies the operation process.

[0026] Among them: the magnetic cover not only provides a sealing effect for the moving blocks, but also allows construction workers to place tools to prevent accidents caused by tools falling.

[0027] Among them: the torsion spring makes the self-locking block have a resistance trend, constantly resists collision, prevents the connection from being too loose, and ensures the tightness of the connection.

[0028] Among them: when the two self-locking blocks collide and form an S-shaped structure, a self-locking mode is formed by the cooperation of the recess and the protrusion, which can enhance the connection stability.

[0029] The grooves and bends on the surface of the self-locking block cooperate with the locking pin and the protrusion to block the moving track of the self-locking block, thereby preventing the self-locking block from moving.

[0030] Among them: with the cooperation of the tapered annular interface, annular socket and self-locking block, the steel body is constrained in both the axial and normal directions, so it is suitable for use in small temporary buildings.

[0031] Among them: Since the moving block is inclined, it can produce a drainage function on rainy days and guide the water flow to prevent excessive moisture inside the wiring path.

[0032] 2. By changing the position of the sliding slot block on the steel body, the angle between the first rib and the second rib can be changed. During transportation, the two can be adjusted to a straight line, which greatly saves transportation space, reduces space occupancy, and makes transportation more convenient and efficient. For example, steel structures that were originally difficult to stack tightly due to the protruding reinforcing ribs can now be arranged neatly. A transport vehicle can carry more quantities, which improves transportation efficiency. Secondly, during the assembly process, construction workers can connect the external lifting equipment and the lifting ring to pull the sliding slot block to move, so that the angle of the first rib and the second rib can be flexibly changed, thereby making precise adjustments according to actual on-site needs.

[0033] Among them: the first rib and the second rib are used to replace the traditional reinforcement ribs, which optimizes the use of materials, effectively saves reinforcement rib related resources, and reduces costs.

[0034] Wherein: by changing the position of the bolt between the first threaded hole and the second threaded hole, the position of the sliding slot block can be locked to ensure that the rib plate functions stably.

[0035] Among them: by using the first rib and the second rib to replace the traditional reinforcement rib, the four groups of ribs cooperate with each other to form a stable support system. The four groups of components are distributed on the outer surface of the steel body, just like multiple fulcrums supporting together, dispersing the force. When the steel body is subjected to external force, the components work together to transmit the force evenly, avoiding the situation where a single point is subjected to excessive force, effectively enhancing the stability and strength of the overall structure, and making up for the possible shortcomings of a single group of structures.

[0036] In summary, the design of adjustable rib plate components has significant advantages in transportation, assembly, resource utilization and structural strength, and can better meet actual construction needs. BRIEF DESCRIPTION OF THE DRAWINGS

[0052] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0053] It should be noted that the external lifting equipment only provides lifting and moving functions for the steel body 11 and the sliding slot block 32. Its working principle and specific structure are both existing technologies. Therefore, in view of the versatility of the external lifting equipment, its specific principle will not be repeated later.

[0054] The present invention is suitable for the construction of temporary factories, and the steel body 11 acts as a pillar in this scenario. Through the rapid splicing of the steel body 11, the construction efficiency of the temporary factory can be significantly improved, which is particularly suitable for scenarios with tight construction schedules and the need to be put into use quickly.

[0055] Example 1, please refer to Figures 1 to 8 as well as Figure 11 As shown, a quick-installed splicing steel structure includes a steel body 11, an automatic interlocking component 2 is provided inside the steel body 11, the automatic interlocking component 2 includes a wiring passage 21 opened inside the steel body 11, a ring interface 22 is opened on the top of the steel body 11, a sealing ring 23 is installed on the top of the steel body 11, and a ring socket 24 is fixedly connected to the bottom of the steel body 11. The outer surface of the steel body 11 is symmetrically rotated and connected to two self-locking blocks 28 with opposite bending directions. A torsion spring 2 is installed between the surface of the self-locking block 28 and the outer surface of the steel body 11. 9. A protective cover 210 is fixedly connected to the outer surface of the steel body 11. The protective cover 210 covers and supports the self-locking block 28, and a snap-fit pin 211 is slidably connected to the inside thereof. The side of the self-locking block 28 away from the torsion spring 29 is concave inward, and the side close to the torsion spring 29 is convex outward. A bend is provided on the surface of the snap-fit pin 211, and the shape of the bend is adapted to the shape of the side of the self-locking block 28 close to the snap-fit pin 211. The steel structure assembled with the steel body 11 needs to be provided with a corresponding annular interface 22 or annular socket 24 to ensure the splicing of the two.

[0056] It should be noted that the side walls of the steel body 11 are symmetrically slidably connected with moving blocks 25, and the side of the moving blocks 25 away from the middle of the steel body 11 is set as an inclined surface, and the sides of the two moving blocks 25 that are close to each other are installed with magnetic covers 26, and the magnetism of the two magnetic covers 26 is opposite. The tops of the two moving blocks 25 are installed with driving members 27 for providing reverse movement function for the two moving blocks 25, and the self-locking blocks 28 are located on the two adjacent sides of the moving blocks 25. The driving member 27 includes a screw rod, two rotating seats, two rotating shafts and two nut seats. The two rotating seats are fixedly connected to the outer surfaces of both sides of the steel body 11, and the screw rod is rotatably connected to the inside of the two rotating seats. The two rotating shafts are respectively installed on both sides of the screw rod, and the thread directions on both sides of the screw rod are opposite. The two nut seats are respectively installed on the tops of the two moving blocks 25, and the two nut seats are both threadedly connected to the outer surface of the screw rod. The annular interface 22 is away from the sealing ring 23. The side gradually shrinks, and the side of the annular socket 24 close to the steel body 11 gradually expands. The shape of the annular socket 24 is adapted to the shape of the annular interface 22. The interior of the sealing ring 23 is arranged to be hollow, and the cross-section of the sealing ring 23 is arranged to be stepped, and the step width gradually decreases from bottom to top. The annular interface 22 and the annular socket 24 are both arranged to be conical, the annular socket 24 is arranged to be hollow, the wiring path 21 is arranged to be a hexagonal path, and its edges are all rounded. The recess and protrusion of the self-locking block 28 form an S-shaped structure, and the recess of the self-locking block 28 can be snapped into the protrusion of another self-locking block 28. Two notches are provided on the side of the self-locking block 28 near the buckling pin 211, and two protrusions are installed on the side of the buckling pin 211 near the self-locking block 28. The shapes of the protrusions are adapted to the shapes of the notches, and the surface of the annular socket 24 is provided with a deformation groove that allows the sealing ring 23 to deform.

[0057] Please refer to Figure 12 As shown, since the steel body 11 only serves as a support, it is necessary to connect the steel body 11 to the two ends of other steel structures during the assembly process, such as beams or other structures. The operator must ensure that the steel structure to be assembled with it must have a ring interface 22 or a ring socket 24, and insert the steel body 11 into the ring interface 22 or the ring socket 24 of the corresponding steel structure through the ring interface 22 or the ring socket 24, so as to ensure the splicing of the two.

[0058] In addition, the steel body 11 can also be used as an adapter to connect between two steel structures. In view of the fact that in actual construction, the two steel structures may be difficult to connect directly due to the existence of fitting tolerance, the annular interface 22 or the annular socket 24 at one end of the steel body 11 can be connected to one of the steel structures, and the other end can be adapted and connected to the other steel structure. This can be used as an adapter to effectively solve the fitting tolerance problem and achieve a stable connection between the two steel structures.

[0059] Specifically, when assembling two steel bodies 11, the construction workers first use an external lifting equipment to lift one steel body 11 to the top of the lower steel body 11. During the lifting process, the construction workers only need to roughly observe the relative position between the two, and do not need to make precise position adjustments like the traditional splicing method. Then, turn on the lifting equipment to slowly lower the upper steel body 11.

[0060] At this time, the annular socket 24 at the bottom of the upper steel body 11 will gradually approach the annular interface 22 at the top of the lower steel body 11. Since the annular interface 22 and the annular socket 24 are both conical structures, when the annular socket 24 is inserted into the annular interface 22, a self-centering effect will be produced. This is because the characteristic of the conical structure is that the closer to the center, the smaller the diameter.

[0061] Therefore, when the annular socket 24 begins to contact the annular interface 22, even if there is a certain deviation between the two in the initial position, as the annular socket 24 gradually goes deeper, the conical wall surface of the annular interface 22 will generate a radial force on the annular socket 24. This force will guide the annular socket 24 to automatically move toward the center of the annular interface 22, so that the centers of the two steel bodies 11 can be quickly aligned to achieve the self-centering function. The self-centering function reduces manual intervention in the alignment process, and only a small amount of manpower is required for simple preliminary alignment to allow the steel structure to quickly enter the splicing process.

[0062] As the upper steel body 11 continues to descend, the sealing ring 23 will be squeezed by the upper steel body 11. The sealing ring 23 has a stepped structure, and its step width gradually decreases from bottom to top. During the extrusion process, the uppermost sealing ring 23 is squeezed and deformed first due to its smaller width. As the extrusion continues, the steps of the lower sealing ring 23 will also deform in turn. Since the sealing ring 23 has a certain elasticity, when it is squeezed, it will gradually deform and fill the gap between the annular interface 22 and the annular socket 24. As the upper steel body 11 further descends, the extrusion force on the sealing ring 23 continues to increase, and its deformation degree also continues to increase. It will eventually be compressed to a planar state, thereby forming a multi-layer structure. This multi-layer structure not only increases the friction, but also greatly improves the sealing between the two steel bodies 11, effectively preventing the invasion of external impurities such as moisture and dust.

[0063] At the same time, when the upper steel body 11 drops to a certain extent, the protrusions of the self-locking blocks 28 on the upper and lower steel bodies 11 will conflict with each other. At the moment of conflict, the two self-locking blocks 28 will rotate in opposite directions, and the torsion spring 29 will be tightened. Since the torsion spring 29 is elastic, when the self-locking block 28 rotates, the torsion spring 29 will store elastic potential energy.

[0064] As the self-locking block 28 continues to rotate, the protrusions of the two will gradually contact each other's recesses. At this time, the torsion spring 29 begins to release part of its elastic potential energy, causing the protrusion of the self-locking block 28 to rotate back to the recess of the other self-locking block 28, thereby achieving the engagement of the two self-locking blocks 28. This engagement method forms a stable S-shaped structure. Through the cooperation of the recess and the protrusion, a self-locking mode is formed, which greatly enhances the stability of the connection.

[0065] When the locking pin 211 is engaged with the notch and bend of the self-locking block 28, the bend of the locking pin 211 will tightly cooperate with the bend of the self-locking block 28, blocking the moving trajectory of the self-locking block 28, thereby effectively preventing the self-locking block 28 from rotating, ensuring that the steel structure after splicing is constrained in both axial and normal directions, and the connection is more firm and reliable. Under the joint action of the annular interface 22, the annular socket 24 and the self-locking block 28, the two steel bodies 11 can be accurately and quickly assembled into one, greatly improving construction efficiency.

[0066] When the steel structure is assembled, it is necessary to lay out the wiring. At this time, the construction personnel only need to rotate the screw in the driving member 27. During the rotation of the screw, the screw will drive the two moving blocks 25 to slide toward the side away from each other under the action of the thread. The sliding of the moving blocks 25 exposes the wiring path 21. At this time, the operator can conveniently perform wiring operations in the wiring path 21. The wiring path 21 is a hexagonal structure. This hexagonal structure has good anti-deformation function. Since each internal angle of the hexagon is 120 degrees, its structure is stable. The sides and corners can support each other and evenly disperse external forces. When subjected to external pressure or tension, the hexagonal structure can better resist deformation, thereby enhancing the structural stability of the steel body 11. At the same time, the hexagonal structure can also provide a larger wiring space in a limited space, making it convenient for operators to perform wiring operations.

[0067] Finally, the operator can choose whether to weld the upper and lower ends of the steel body 11 according to actual requirements.

[0068] It should be noted that the side of the moving block 25 away from the middle of the steel body 11 is set as an inclined surface. On rainy days, rainwater will fall on the inclined surface of the moving block 25. Due to the existence of the inclined surface, the rainwater will flow along the direction of the inclined surface, thereby producing a drainage function. The inclined surface of the moving block 25 can guide the rainwater away from the wiring path 21, prevent rainwater from entering the interior of the wiring path 21, avoid excessive moisture inside the wiring path 21, and protect the safety and stable operation of the line.

[0069] Example 2: Based on Example 1, please refer to Figure 1 , Figure 9 and Figure 10 As shown, an adjustable rib assembly 3 is provided on the outside of the steel body 11, and the adjustable rib assembly 3 includes four limit rail blocks 31. The limit rail blocks 31 are all arranged in a rectangular and equidistant manner and installed on the outer surface of the steel body 11. The outer surfaces of the limit rail blocks 31 are slidably connected with sliding slot blocks 32. The outer surfaces of the sliding slot blocks 32 are arranged in a rectangular and equidistant manner and are rotatably connected to the first ribs 33. The outer surface of the steel body 11 is arranged in a rectangular and equidistant manner and is rotatably connected to a number of second ribs 34. The bottoms of the second ribs 34 are rotatably connected to the tops of the first ribs 33. The bottoms of the sliding slot blocks 32 are arranged in a rectangular and equidistant manner and are fixedly connected to support plates 35. The bottom of each limit rail block 31 is linearly and equidistantly arranged and symmetrically provided with first threaded holes 36. The bottom of each support plate 35 is provided with a second threaded hole, and bolts 37 are installed in the second threaded holes.

[0070] It should be noted that the bolt 37 can also be threadedly connected to the inside of the first threaded hole 36, and the side of the support plate 35 away from the bolt 37 is set to a trapezoidal shape. Several lifting rings are installed on the outer surface of the sliding groove block 32, and the lifting rings can change the position of the sliding groove block 32 on the steel body 11 through the operation of an external lifting device.

[0071] Specifically, when the steel body 11 needs to be transported to the construction area, the construction workers need to unscrew the bolts 37 from the first threaded hole 36 and the second threaded hole. The purpose of this operation is to release the position lock of the sliding slot block 32 so that it can move freely. Then, the construction workers pull the sliding slot block 32 to the side away from the annular socket 24. During this process, the movement of the sliding slot block 32 will directly drive the first rib 33 connected to it to move synchronously.

[0072] Since the first rib 33 and the second rib 34 are rotationally connected, and the bottom of the second rib 34 is rotationally connected to the top of the first rib 33, as the first rib 33 moves, the angle between the first rib 33 and the second rib 34 will gradually become smaller. When the sliding groove block 32 moves to the appropriate position, the first rib 33 and the second rib 34 will eventually be in a three-point straight line state. In this way, during transportation, the problem of occupying a large amount of space due to the protruding traditional reinforcing ribs is effectively solved. The steel structures that were originally difficult to stack tightly due to the protruding reinforcing ribs can now be arranged neatly. More steel bodies 11 can be loaded within the fixed capacity of the transport vehicle, which greatly improves transportation efficiency and reduces transportation costs.

[0073] After the steel body 11 is transported to the construction area and assembled, the adjustable stiffener assembly 3 needs to be adjusted so that it can meet the structural stability requirements of temporary buildings and small buildings.

[0074] The construction personnel first operate the external lifting equipment and connect the hook of the external lifting equipment with the lifting ring on the sliding slot block 32. After the connection is completed, the operator unscrews the bolt 37 from the first threaded hole 36 and the second threaded hole again to release the position lock of the sliding slot block 32, so that it can move under the action of external force. Then, the construction personnel operate the external lifting equipment to rise. The external lifting equipment will drive the sliding slot block 32 to move upward through the lifting ring. As the sliding slot block 32 moves, the first rib 33 connected to its surface will also move synchronously. Since the second rib 34 is in a rotational connection with the steel body 11, and the bottom of the second rib 34 is rotationally connected to the top of the first rib 33, as the first rib 33 rises, the connection point between the second rib 34 and the first rib 33 will also rise, and the angle between the two will gradually increase.

[0075] Subsequently, the construction workers precisely adjusted the angle between the first rib 33 and the second rib 34 by controlling the rising height of the external lifting equipment according to the actual needs of the site. When the connection point and angle of the first rib 33 and the second rib 34 reached the appropriate position, the construction workers re-screwed the bolt 37 into the first threaded hole 36 and the second threaded hole. In this way, the position of the sliding slot block 32 is re-locked, and the first rib 33 and the second rib 34 are also fixed in the appropriate position again, which can stably play the role of strengthening the structure.

[0076] It should be noted that the use of the first ribs 33 and the second ribs 34 instead of traditional reinforcing ribs not only brings significant advantages in transportation and installation, but also can meet the needs of temporary buildings and small buildings in terms of structural performance. In temporary buildings and small buildings, the loads borne by the structure are relatively small. Although the strength and stability requirements for the reinforcing ribs are not as high as those of large buildings, it is still necessary to ensure the safety and reliability of the structure during use. The combined structure of the first ribs 33 and the second ribs 34 can effectively share the forces borne by the steel body 11 in all directions. Each group of first ribs 33 and second ribs 34 is responsible for connecting and supporting the steel body 11 in one direction. They can evenly distribute the external forces exerted on the steel body 11 throughout the structure, avoiding local stress concentration. In the actual stress-bearing process, when the steel body 11 is subjected to pressure or tension from a certain direction, the first ribs 33 and the second ribs 34 will work together to transmit the external forces to other parts through the rotational connection between them and the connection points with the steel body 11, thereby enhancing the overall structural stability of the steel body 11.

[0077] This structural design not only meets the structural stability requirements of temporary buildings and small buildings, but also optimizes the use of materials, effectively saves resources related to reinforcing ribs, and reduces costs.
