Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, and in particular, to a modular steel structure unit for highway service areas that can be spliced ​​and assembled. Background Technology

[0002] With the increasing traffic flow on my country's expressway network year by year, the existing service areas built in the early stages can no longer meet modern needs in terms of spatial capacity, functional zoning, and intelligent adaptability, resulting in a large number of service areas facing upgrades and renovations; in addition, new service areas are constantly being built to adapt to modern needs.

[0003] Currently, service areas mostly adopt fixed building structures, mainly including two structural forms: reinforced concrete structures and steel frame structures. Among them, steel frame structures have advantages such as short construction period and large space, and are often used in newly built service areas in recent years. However, when facing the expansion or functional adjustment of service areas, fixed building structures have problems such as insufficient flexibility in modification and poor functional adaptability, and cannot adapt to the needs of further changes in future traffic flow.

[0004] Therefore, it is necessary to propose a modular steel structure unit for highway service areas that can be assembled and disassembled. Through standardized and modular design, the modular installation, rapid expansion, functional reconfiguration, and material recycling of service area buildings can be achieved. Utility Model Content

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A modular steel structure unit for highway service areas that can be assembled and disassembled includes steel support columns, arc-shaped braces, steel horizontal main beams, steel horizontal secondary beams, and edge sealing beams. The first end of the steel horizontal main beam is fixed to the top of the steel support column, and the second end of the steel horizontal main beam extends horizontally outward and is cantilevered. Four steel horizontal main beams are evenly spaced around the steel support column. The arc-shaped braces are arranged one-to-one with the steel horizontal main beams. The first end of the arc-shaped brace is fixed to the steel support column, and the second end of the arc-shaped brace extends upward and supports the corresponding steel horizontal main beam from the bottom of the steel horizontal main beam. The edge sealing beams are fixed between the cantilevered and radiating ends of two adjacent steel horizontal main beams. The four edge sealing beams enclose a rectangular frame. Multiple sets of steel secondary beams are respectively arranged within the triangles formed by the steel horizontal main beams and the edge sealing beams. Each set of steel secondary beams includes two steel horizontal secondary beams arranged perpendicular to the steel horizontal main beams. One end of the steel horizontal secondary beam overlaps the corresponding steel horizontal main beam, and the other end of the steel horizontal secondary beam overlaps the corresponding edge sealing beam.

[0008] Furthermore, the curved bracing is arranged in a curved manner away from the main steel beam, and the curved bracing is arranged inside the secondary steel beam.

[0009] Furthermore, the first end of the steel transverse secondary beam is erected on the mid-section of the steel transverse main beam, and the second end of the steel transverse secondary beam is erected on the middle of the edge sealing beam.

[0010] Furthermore, the steel support column includes an anchoring base, a support steel column, and a connecting top seat. The anchoring base is located at the bottom end of the support steel column, and the connecting top seat is located at the top end of the support steel column. The connecting top seat includes a connecting top plate. Four connecting top plates are evenly spaced along the circumference on the support steel column. The steel horizontal main beam is arranged in a one-to-one correspondence with the connecting top plate. The first end of the steel horizontal main beam is welded or bolted to the corresponding connecting top plate.

[0011] Furthermore, the supporting steel column is a cross-shaped steel column composed of vertically intersecting double I-beams. The connecting top seat is welded to the extended end of the cross-shaped steel column and fixed by reinforcing ribs. The four connecting top seats are evenly spaced along the four sides.

[0012] Furthermore, the arc-shaped brace includes a detachably connected arc-shaped connecting section and an arc-shaped brace end. The bottom end of the arc-shaped connecting section is fixed to the steel support column, and the top end of the arc-shaped connecting section is provided with an arc-shaped brace section, which extends upward and supports the steel horizontal main beam.

[0013] Furthermore, the arc-shaped connecting section and the arc-shaped diagonal brace section are detachably connected by connecting side plates and connecting bolts.

[0014] Furthermore, the arc-shaped connecting section and the arc-shaped diagonal brace section are detachably connected by connecting side plates and connecting bolts. One end of the connecting side plate is fixed to the arc-shaped connecting section by connecting bolts, and the other end of the connecting side plate is fixed to the arc-shaped diagonal brace section by connecting bolts.

[0015] Furthermore, adjacent, horizontally or vertically adjacent steel structure modular units of the highway service area share a single edge sealing beam.

[0018] This utility model has the following beneficial effects:

[0019] This utility model discloses a modular steel structure unit for highway service areas that can be assembled and disassembled. It includes steel support columns, curved braces, main steel horizontal beams, secondary steel horizontal beams, and edge sealing beams. The modular frame is formed by the interconnection of one steel support column, four curved braces, four main steel horizontal beams, eight secondary steel horizontal beams, and four edge sealing beams. During the construction or renovation of the service area, each modular frame can be assembled as a unit, and two adjacent modular frames share a single edge sealing beam. This solves the technical problem of insufficient flexibility in renovation caused by the fixed building structure used in existing highway service areas. Furthermore, by setting steel support columns as supporting members, and with the main steel horizontal beams cantilevered at the top of the steel support columns and supported by curved braces at the cantilever ends, the spatial hyperboloid lateral force resisting system formed by the four curved braces and the steel support columns reduces the cross-sectional dimensions of independent support columns.

[0033] like Figure 1 , Figure 2 and Figure 3As shown, this utility model provides a modular steel structure unit 100 for highway service areas that can be assembled and spliced. It includes steel support columns 10, arc-shaped diagonal braces 20, main steel horizontal beams 30, secondary steel horizontal beams 40, and edge-sealing beams 50. The first end of the main steel horizontal beam 30 is fixed to the top of the steel support column 10, and the second end of the main steel horizontal beam 30 extends horizontally outward and is cantilevered. Four main steel horizontal beams 30 are evenly spaced around the steel support column 10. The arc-shaped diagonal braces 20 are arranged corresponding to the main steel horizontal beams 30, and the first end of each arc-shaped diagonal brace 20 is fixed to the steel support column 10. The second end of the arc-shaped diagonal brace 20 extends upward and supports the corresponding steel horizontal main beam 30 from the bottom of the steel horizontal main beam. The edge sealing beam 50 is fixed between the cantilevered radiating ends of two adjacent steel horizontal main beams 30. The four edge sealing beams 50 enclose a rectangular frame. Multiple sets of steel secondary beams are respectively set in the triangle formed by the steel horizontal main beams 30 and the edge sealing beams 50. Each set of steel secondary beams includes two steel horizontal secondary beams 40 arranged perpendicular to the steel horizontal main beams 30. One end of the steel horizontal secondary beam 40 overlaps the corresponding steel horizontal main beam 30, and the other end of the steel horizontal secondary beam 40 overlaps the corresponding edge sealing beam 50.

[0034] This utility model provides a modular steel structure unit 100 for highway service areas that can be assembled and spliced. It includes steel support columns 10, arc-shaped diagonal braces 20, main steel horizontal beams 30, secondary steel horizontal beams 40, and edge sealing beams 50. The modular frame is formed by the interconnection of one steel support column 10, four arc-shaped diagonal braces 20, four main steel horizontal beams 30, eight secondary steel horizontal beams 40, and four edge sealing beams 50. During the construction or renovation of the service area, the modular frame can be assembled as a unit, and two adjacent modular frames share one edge sealing beam 50. This solves the problem of existing highway service areas... The use of fixed building structures leads to insufficient flexibility in renovation. At the same time, by setting steel support columns 10 as support members, and the steel horizontal main beam 30 cantilevered at the top of the steel support columns 10 with the cantilever end supported by arc-shaped diagonal braces 20, the spatial hyperboloid lateral force resisting system formed by the four arc-shaped diagonal braces 20 and the steel support columns 10 can reduce the cross-sectional size of independent support columns. At the same time, the large space at the bottom of the arc-shaped diagonal braces 20 is conducive to improving space utilization. By adding steel horizontal secondary beams 40 and edge sealing beams 50 between the steel horizontal main beams 30, the overall stability of the structure can be increased and support can be provided for the upper roof system.

[0035] Furthermore, the curved brace 20 is arranged in a curved configuration away from the main steel beam 30, and is located inside the secondary steel beam 40. Understandably, the curved brace 20's arrangement away from the main steel beam 30 and inside the secondary steel beam 40 optimizes the internal space of the structure, making the bottom of the entire steel structure modular frame wider and improving space utilization. Simultaneously, the curved brace 20 has elastic deformation capacity and a certain degree of recovery performance after load impact, resulting in strong overall structural stability. Even better, reinforcing ribs are added at the bend of the curved brace 20 to further improve its load-bearing capacity.

[0036] Furthermore, the first end of the steel secondary beam 40 is erected on the mid-section of the steel main beam 30, and the second end of the steel secondary beam 40 is erected on the middle of the edge sealing beam 50. In this utility model, the first end of the steel secondary beam 40 is erected on the mid-section of the steel main beam 30, and the second end is erected on the middle of the edge sealing beam 50. This allows the steel secondary beam 40 to connect the steel main beam 30 and the edge sealing beam 50 more stably, ensuring more direct and uniform force transmission, enhancing the stability of the structure within the triangular area, effectively distributing and transmitting loads, reducing stress concentration, and improving the safety and reliability of the entire steel structure modular frame.

[0037] Furthermore, the steel support column 10 includes an anchoring base, a supporting steel column, and a connecting top seat. The anchoring base is located at the bottom end of the supporting steel column, and the connecting top seat is located at the top end of the supporting steel column. The connecting top seat includes a connecting top plate, with four connecting top plates evenly spaced circumferentially on the supporting steel column. The steel horizontal main beam 30 is arranged in a one-to-one correspondence with the connecting top plate, and the first end of the steel horizontal main beam 30 is welded or bolted to the corresponding connecting top plate. Understandably, designing the steel support column 10 as a combined structure including the anchoring base, supporting steel column, and connecting top seat, with the connecting top plate of the connecting top seat corresponding to the steel horizontal main beam 30 and being fixedly connected by welding or bolts, serves two purposes. First, the anchoring base allows the steel support column 10 to be more firmly anchored in the foundation, improving the overall structure's pull-out and overturning resistance. Second, the modular design facilitates processing, transportation, and installation.

[0038] Furthermore, the supporting steel column is a cross-shaped steel column composed of vertically intersecting double H-beams. The connecting top seat is welded to the extended end of the cross-shaped steel column and fixed by reinforcing ribs. The four connecting top seats are evenly spaced around the perimeter. In this utility model, the supporting steel column is a cross-shaped steel column composed of vertically intersecting double H-beams, which has high load-bearing capacity and lateral stiffness, and can effectively resist horizontal and vertical loads. The connecting top seat is welded to the extended end of the cross-shaped steel column and fixed by reinforcing ribs, ensuring the firmness and reliability of the connection between the connecting top seat and the supporting steel column. The four connecting top seats are evenly spaced around the perimeter, so that the steel horizontal main beam 30 can be evenly distributed around the steel supporting column 10, forming a symmetrical and stable structural system, which is conducive to improving the stability and stress uniformity of the entire steel structure module frame.

[0039] Understandably, by setting the supporting steel columns as vertically intersecting double I-beams, the section moment of inertia is increased, further enhancing the bidirectional bending capacity, and the open section facilitates inspection, painting and maintenance.

[0040] Furthermore, the arc-shaped diagonal brace 20 includes a detachably connected arc-shaped connecting section 21 and an arc-shaped diagonal brace 20 end. The bottom end of the arc-shaped connecting section 21 is fixed to the steel support column 10, and the top end of the arc-shaped connecting section 21 is provided with an arc-shaped diagonal brace 20 segment. The arc-shaped diagonal brace 20 segment extends upward and supports the steel horizontal main beam 30. The arc-shaped diagonal brace 20 adopts a detachably connected arc-shaped connecting section 21 and an arc-shaped diagonal brace 20 end, which facilitates the installation, disassembly, and replacement of the arc-shaped diagonal brace 20. During transportation, the arc-shaped connecting section 21 and the arc-shaped diagonal brace 20 segment can be separated to reduce transportation volume and reduce transportation costs. During on-site installation, the assembly of the arc-shaped diagonal brace 20 can be flexibly adjusted according to actual needs, improving the convenience and flexibility of construction, and also facilitating the maintenance and repair of the arc-shaped diagonal brace 20, extending the service life of the structure. Furthermore, a sealing strip is provided at the connection between the arc-shaped connecting section 21 and the arc-shaped diagonal brace 20 segment. The arc-shaped diagonal brace 20 has a quarter-circle arc structure.

[0041] Understandably, in one specific embodiment, four arc-shaped diagonal braces 20 are located around the independent steel column, and the included angle between the projections of adjacent diagonal braces on the horizontal plane is 90°; the steel horizontal main beam 30 is perpendicularly connected to the steel support column 10; the edge sealing beam 50 is connected to the four steel horizontal main beams 30 at a 45-degree angle and is arranged in a square around the perimeter of the module; the steel horizontal secondary beam 40 is perpendicularly connected to the steel horizontal main beams 30 at the plane projection position of the arc-shaped diagonal braces 20, and is connected to the edge sealing beam 50 at a 45-degree angle.

[0042] Furthermore, the arc-shaped connecting segment 21 and the arc-shaped diagonal brace 20 are detachably connected via connecting side plates and connecting bolts. In this invention, the detachable connection between the arc-shaped connecting segment 21 and the arc-shaped diagonal brace 20 is achieved through connecting side plates and connecting bolts. The connection method is simple and reliable, and the installation and disassembly operations are convenient and quick, requiring no special tools or complex processes, thus saving construction time and labor costs. At the same time, the connecting side plates can increase the local strength and stiffness at the connection point, ensuring the overall stability and load-bearing performance of the arc-shaped diagonal brace 20, and ensuring the safety and reliability of the structure during use.

[0043] Please refer to Figure 4 and Figure 5 The modular steel structure units 100 of the highway service area, which can be assembled and spliced ​​together horizontally or vertically, share a single edge-sealing beam 50. Optionally, a roof surface is laid on the top surface of the steel structure module frame, and adjacent steel structure module frames share a single edge-sealing beam 50. This enables modular construction and renovation of the service area. The sharing of the edge-sealing beam 50 by adjacent modules reduces the number of components and connection nodes, simplifies the structural system, and improves the overall stability and reliability of the structure. At the same time, subsequent expansion and renovation have little impact on the structure of existing buildings, and can better adapt to different functional needs and scale changes of the service area.

[0044] Furthermore, its shape is L-shaped or rectangular.

[0045] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
