Description

Technical Field

[0001] This invention relates to the field of campus education building technology, and in particular to a large-span steel frame-glulam tensioned beam structure system suitable for indoor sports fields. Background Technology

[0002] Conventional large-span stadiums and indoor sports fields often use steel structures as their main structure. According to DB32T4880-2024 "Calculation Standard for Carbon Emissions of Civil Buildings", the carbon emissions per unit area of ​​steel structures are the highest during the production, transportation and construction stages of building materials, reaching 820-1000 kgCO2e / m². The emission reduction ratio compared with concrete structures is -100% to -145%. The selection of high-carbon emission structures will lead to the consumption of fossil energy and mineral resources, as well as direct and indirect problems to the natural environment. Summary of the Invention

[0003] To address the problems associated with using steel structures as the main structure in conventional large-span stadiums and indoor sports fields, this invention provides a large-span steel frame-glulam tensioned beam structure system suitable for indoor sports fields. This invention utilizes a steel frame-glulam tensioned beam structure system, which can effectively save steel consumption, reduce carbon emissions, and simultaneously reduce the structural self-weight and the load on the bottom reinforced concrete foundation.

[0004] The technical solution of this invention is as follows:

[0005] A large-span steel frame-glulam tensioned beam structure system suitable for indoor sports fields includes multiple spaced individual load-bearing modules. Each individual load-bearing module comprises a glulam tensioned beam structure and two steel lattice columns. The two ends of the glulam tensioned beam structure are connected to the two steel lattice columns. The steel lattice columns of multiple individual load-bearing modules are interconnected to form a steel frame structure. The glulam tensioned beam structures of multiple individual load-bearing modules form a roof structure. The roof structure is equipped with multiple stabilizing timber trusses to ensure the out-of-plane stability of the roof structure. The roof structure is equipped with transverse horizontal supports and longitudinal horizontal supports to ensure the in-plane stiffness of the roof structure.

[0006] As a preferred embodiment of the present invention, the glued laminated timber tensioned beam structure includes an upper chord glued laminated timber beam, a lower chord cable, and a plurality of vertically arranged glued laminated timber struts. The upper chord glued laminated timber beam is connected to two steel lattice columns at both ends. The upper chord glued laminated timber beam and the lower chord cable are hinged together by the plurality of glued laminated timber struts. The lower chord cable is fixed at both ends to the steel lattice columns on both sides. By applying prestress to the lower chord cable, the tension force of the lower chord cable is converted into a lifting force on the upper chord glued laminated timber beam through the glued laminated timber struts to form a cable-stayed system.

[0007] As a preferred embodiment of the present invention, the upper chord glued laminated timber beam is a variable cross-section beam with an upward convex shape.

[0008] As a preferred embodiment of the present invention, the upper chord glued laminated timber beam is provided with a timber frame, and the timber frame is used to install a skylight.

[0009] As a preferred embodiment of the present invention, the skylight is arranged longitudinally along the roof structure between each individual load-bearing module.

[0010] As a preferred embodiment of the present invention, the skylight is perpendicular to the horizontal plane.

[0011] As a preferred embodiment of the present invention, one of the multiple stabilizing timber trusses is arranged along the ridge line of the roof structure, and the remaining stabilizing timber trusses are symmetrically arranged on both sides of the ridge line of the roof structure.

[0012] As a preferred embodiment of the present invention, the multi-stabilized timber truss includes a first stabilized timber truss, two second stabilized timber trusses, and two third stabilized timber trusses. The first stabilized timber truss is arranged along the ridge line of the roof structure. The two second stabilized timber trusses are arranged in parallel and symmetrically on both sides of the first stabilized timber truss, and the two third stabilized timber trusses are arranged in parallel and symmetrically on both sides of the second stabilized timber trusses.

[0013] As a preferred embodiment of the present invention, the transverse horizontal support includes a steel diagonal brace assembly and a timber diagonal brace assembly. The steel diagonal brace assembly is disposed in the end slots of multiple single load-bearing modules and is located on the outside of the third stable timber truss. The timber diagonal brace assembly is disposed between two adjacent single load-bearing modules and is located between the first stable timber truss and the second stable timber truss.

[0014] As a preferred embodiment of the present invention, the longitudinal horizontal support includes cross steel bracing, which is disposed between two adjacent single load-bearing modules and located between the second and third stable timber trusses.

[0015] As a preferred embodiment of the present invention, an enclosure structure is provided around the plurality of individual load-bearing modules to enclose and form a covered playground space.

[0016] As a preferred embodiment of the present invention, the plurality of individual load-bearing modules are installed in a directly exposed form inside the enclosure structure.

[0017] As a preferred embodiment of the present invention, the wooden components of the plurality of individual load-bearing modules are all coated with a transparent fire-retardant coating, and the fire-retardant effect is achieved by the carbonized layer generated when the transparent fire-retardant coating burns.

[0018] As a preferred embodiment of the present invention, a steel frame is provided on the steel frame structure inside the enclosure structure, and the steel frame surrounds the steel frame structure.

[0019] As a preferred embodiment of the present invention, a running track is provided on the steel frame and guardrails are provided on both sides of the running track. The running track surrounds the steel frame structure and is higher than the ground.

[0020] The advantages of this invention are:

[0021] Compared to the traditional all-steel structure design of indoor sports fields, this invention adopts a steel frame-glulam tensioned beam structure system, which can significantly save on steel usage. Moreover, as a renewable material, wood has a carbon emission factor of only 3.41% that of steel. By reducing the amount of steel structure materials, carbon emissions can be reduced by about 30%. At the same time, due to the low density of wood, the structure is lighter, which indirectly reduces the load on the underlying reinforced concrete structure.

[0022] The main structure of the indoor sports field is directly exposed. The wood is fireproofed by transparent fire-retardant coating and the carbonized layer produced when it burns. The interior design eliminates unnecessary interior decoration layers, which not only reduces carbon emissions from interior decoration construction and auxiliary materials, but also creates a comfortable and pleasant interior space through the warm color and texture of the wood itself. With a simple construction logic, it conveys a unique low-carbon design aesthetic to the public and students.

[0023] This invention is based on the green, low-carbon, and sustainable development of buildings and the needs of educational functions. It integrates climate adaptation, resource sharing, and ecological compensation into the design, not only meeting the functional requirements of educational buildings but also serving as a practical carrier for promoting green and low-carbon concepts. Educational buildings are the most direct material carriers for young people to experience and practice education. The practical exploration of ultra-low-energy buildings constructed with steel and wood structures in educational buildings can not only serve as a model for the future green and low-carbon development of educational buildings but also better promote science popularization to the public. Against the backdrop of global climate change and the "dual carbon" goal, it promotes the development of the construction industry towards a green, low-carbon, and sustainable direction.

[0045] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0046] like Figures 1-11 As shown, this embodiment is a large-span steel frame-glulam tensioned beam structure system suitable for indoor sports fields. It includes multiple spaced individual load-bearing modules 1. Each individual load-bearing module 1 includes a glulam tensioned beam structure and two steel lattice columns 10. The two ends of the glulam tensioned beam structure are connected to the two steel lattice columns 10. The steel lattice columns 10 of the multiple individual load-bearing modules 1 are interconnected to form a steel frame structure 20. The glulam tensioned beam structures of the multiple individual load-bearing modules 1 form a roof structure 30. The roof structure 30 is equipped with multiple stabilizing timber trusses to ensure the out-of-plane stability of the roof structure 30. The roof structure 30 is equipped with transverse horizontal supports and longitudinal horizontal supports to ensure the in-plane stiffness of the roof structure 30.

[0047] like Figure 3 As shown, in this embodiment, the glued laminated timber (GLTL) tensioned beam structure includes an upper chord GLTL beam 11, a lower chord cable 12, and multiple vertically arranged GLTL struts 13. The upper chord GLTL beam 11 is connected to two steel lattice columns 10 at both ends. The upper chord GLTL beam 11 and the lower chord cable 12 are hinged together by the multiple GLTL struts 13. The lower chord cable 12 is fixed at both ends to the steel lattice columns 10 on both sides. By applying prestress to the lower chord cable 12, the tension force of the lower chord cable 12 is converted into a lifting force on the upper chord GLTL beam 11 through the GLTL struts 13 to form a cable support system, which bears the roof load and ensures the safety and reliability of the large-span steel-timber structure.

[0048] This embodiment has eleven single-frame load-bearing modules 1, and the roof structure 30 is composed of eleven glued laminated timber (GLLT) tensioned beam structures. Each GLLT tensioned beam structure consists of an upper chord GLLT beam 11, a prestressed lower chord cable 12, and five GLLT struts 13 forming a cable-stayed system. The upper chord GLLT beam 11 is a variable cross-section beam with an upward convex shape and a cross-sectional dimension of 350mm x 800mm to 350mm x 400mm, ensuring that the cable-stayed system is in a stable and balanced state. The diameter of the GLLT struts 13 is 250mm, and the maximum height of the GLLT strut 13 is 2.75m. Figures 3-5 As shown, a timber frame 14 is installed on the upper chord glued laminated timber beam 11. The timber frame 14 is used to install skylights 3 to meet the indoor lighting requirements of the covered playground; as Figure 12 and 13 As shown, the skylights 3 are arranged longitudinally along the roof structure 30 between each individual load-bearing module 1, and the skylights 3 are perpendicular to the horizontal plane to form a side-opening window. The array of skylights 3 arranged longitudinally along the roof structure 30 can achieve uniform lighting in the indoor playground. The side-opening window form an angle with the line of sight of students during activities in the indoor playground, effectively avoiding glare problems. The skylights 3 are operable. In practical applications, it is recommended that operable skylights 3 be driven by electric push rods for opening and closing.

[0049] like Figures 7-11 As shown, in this embodiment, one of the multiple stabilizing timber trusses is arranged along the ridge line of the roof structure 30, and the remaining stabilizing timber trusses are symmetrically arranged on both sides of the ridge line of the roof structure 30. Specifically, the multiple stabilizing timber trusses include a first stabilizing timber truss 31, two second stabilizing timber trusses 32, and two third stabilizing timber trusses 33. The first stabilizing timber truss 31 is arranged along the ridge line of the roof structure 30, the two second stabilizing timber trusses 32 are arranged in parallel and symmetrically on both sides of the first stabilizing timber truss 31, and the two third stabilizing timber trusses 33 are arranged in parallel and symmetrically on both sides of the two second stabilizing timber trusses 32.

[0050] like Figure 4 and Figure 7 As shown, in this embodiment, the lateral horizontal support includes a steel diagonal brace assembly 4 and a wooden diagonal brace assembly 5. The steel diagonal brace assembly 4 is disposed in the end slots of multiple single force-bearing modules 1 and is located on the outside of the stable wooden truss 33. The wooden diagonal brace assembly 5 is disposed between two adjacent single force-bearing modules 1 and is located between the stable wooden truss 1 31 and the stable wooden truss 2 32. The longitudinal horizontal support includes a cross steel diagonal brace 6, which is disposed between two adjacent single force-bearing modules 1 and is located between the stable wooden truss 2 32 and the stable wooden truss 33.

[0051] In this embodiment, five stable timber trusses are set along the plane of the roof structure 30 to ensure the out-of-plane stability of the glued laminated timber tensioned beam structure. The end-span steel diagonal bracing assembly 4 and the timber diagonal bracing assembly 5 between the single load-bearing modules 1 together form the transverse horizontal support of the roof structure 30. The cross steel diagonal bracing 6 between the single load-bearing modules 1 constitutes the longitudinal horizontal support of the roof structure 30. The roof structure 30, together with the stable timber trusses, transverse horizontal support, and longitudinal horizontal support, forms the load-bearing components. The roof load is transferred to the steel lattice columns 10 on both sides through the glued laminated timber tensioned beam structure, and then transferred to the foundation through the lower reinforced concrete frame structure 2.

[0052] like Figure 12 and 13 As shown, in this embodiment, an enclosure structure is set around multiple individual load-bearing modules 1 to form an enclosed playground space, effectively separating the indoor and outdoor areas; this embodiment uses a reinforced concrete frame structure 2 as the foundation, referring to... Figure 1 As shown; multiple individual load-bearing modules 1 are installed in the interior of the building envelope in a directly exposed manner, such as... Figure 13 As shown, the wooden components of multiple individual load-bearing modules 1 are all coated with transparent fire-retardant paint, and the fire-retardant effect is achieved by the carbonized layer generated when the transparent fire-retardant paint burns.

[0053] like Figure 2 , Figure 3 as well as Figure 6As shown, in this embodiment, a steel frame 21 is installed on the steel frame structure 20 inside the enclosure structure, and the steel frame 21 surrounds the steel frame structure 20; as Figure 13 As shown, a running track 7 is set on the steel frame 21 and guardrails are set on both sides of the running track 7. The running track 7 surrounds the steel frame structure 20 and is higher than the ground. The running track 7 makes full use of the mezzanine space of the steel frame structure 20, does not occupy the ground area, and greatly improves the utilization rate of the ground activity space.

[0054] The covered playground constructed in this embodiment has multiple functional spaces, such as... Figure 1 and Figure 6 As shown, the first and second floors are kitchens and canteens, using a reinforced concrete frame structure. The third-floor covered playground and its mezzanine use a steel frame-glulam tensioned beam structure. The net height of the third-floor covered playground is 9m, and the maximum span is 34.8m. The steel frame-glulam tensioned beam structure is a self-balancing structural system with a combination of rigidity and flexibility, which is composed of multiple single-frame load-bearing modules 1.
