Description

Technical Field

[0001] This application relates to the field of architectural construction technology, and in particular to a structural system combining steel cables and steel and wood, and its construction method. Background Technology

[0002] Timber-structure building systems are structures that use wood as the primary load-bearing component. Due to the lightweight nature of wood and advancements in wood preservation technology, timber structures are suitable for use in large-span building structures. Furthermore, the environmentally friendly, warm, and natural characteristics of timber structures evoke feelings of intimacy, friendliness, happiness, and tranquility, making timber-structure building systems increasingly popular.

[0003] Therefore, timber structures can be used in large public buildings (such as exhibition halls) to achieve the construction of large-span building structures, thereby enabling the use of large interior spaces.

[0004] In existing technology, there exists an umbrella-shaped timber structure system, which includes timber columns and a roof frame. This system supports the roof structure of the building. The roof frame is mounted on the timber columns, making the entire structure resemble an umbrella. The roof structure is laid on the roof frame and can be made of materials such as translucent glass or a roof membrane, allowing sunlight to penetrate into the building.

[0005] To ensure the strength of the connection between the wooden columns and the roof frame, several steel beams are also installed between the columns and the frame to improve the overall structural stability. When this wooden structure system is applied to the atrium of the exhibition hall, the numerous steel beams between the columns and the frame obstruct the view of people looking up at the roof, affecting their viewing experience and the overall aesthetic of the building. Summary of the Invention

[0006] In a timber structure system, in order to improve the permeability of the connection area between the timber columns and the roof timber frame and enhance the overall aesthetic effect of the building, this application provides a structural system of steel cables and steel-timber combination and its construction method.

The roof frame is composed of several wooden beams spliced ​​and fixed, and an inner ring is provided in the middle of the roof frame. The beam-column connection nodes of the wooden columns and the roof frame are arranged around the inner ring. The steel ring beam is arranged in the inner ring and is fixedly connected to the roof frame. The fixing components are arranged inside the steel ring beam and are fixedly connected to the steel ring beam. The fixing components include steel connectors and several upper chord steel cables. One end of the upper chord steel cable is fixedly connected to the steel ring beam, and the other end of the upper chord steel cable is fixedly connected to the steel connector.

Steel connectors are connected to the steel ring beam via several upper chord steel cables; that is, through the coordinated action of the fixing components and the steel ring beam, the roof frame structure can be stably supported. Therefore, when people look up at the roof frame from the ground, the obstruction of the view by the connection structure between the wooden columns and the roof frame is reduced, improving the viewing experience.

[0016] By employing the above technical solution, a wooden column is formed by splicing together several arc-shaped wooden pillars, thus creating a large-area first column ring at the base of the wooden column, thereby improving the stability of the connection between the wooden column and the ground. Simultaneously, a large-area second column ring is formed at the top of the wooden column, resulting in a large hollow area in the upper part of the structural system, thereby improving the permeability of the central part of the structural system and enhancing the overall effect of the building.

[0018] By adopting the above technical solution, the column connector is fixed on the wooden column. After the two ends of the column steel cable are connected to the column connector of the adjacent wooden column, the connection strength between the adjacent wooden columns is further strengthened by the column steel cable, thereby improving the stability and load-bearing capacity of the wooden column.

[0040] The following is in conjunction with the appendix Figure 1-14 This application will be described in further detail.

[0041] This application discloses a structural system combining steel cables and steel-wood composite materials. (Refer to...) Figure 1 and Figure 2 The steel cable and steel-wood composite structural system of this application is applied to the atrium area of ​​a large public building. Large public buildings can be used for art galleries, libraries, exhibition halls, etc.; in this embodiment, the large public building is a scientific research and exhibition center.

[0042] Reference Figure 1 and Figure 2In this embodiment, the large public building includes a concrete main body 1, the steel cable and steel-wood composite structural system of this application, and a roof membrane structure. The concrete main body 1 has a large atrium space in its center. The steel cable and steel-wood composite structural system is located within this atrium space and is fixedly connected to the concrete main body 1 on its outer perimeter. The roof membrane structure is laid on top of the steel cable and steel-wood composite structural system and is fixedly connected to the concrete main body 1; thus, the roof membrane structure covers the upper part of the atrium area of ​​the large building, separating the interior space of the large public building from the outside. Roof membrane structures have many implementations in the prior art, and the roof membrane structure is not the main inventive point of this application; therefore, the roof membrane structure is not shown in the accompanying drawings in this embodiment.

[0043] Reference Figure 2 and Figure 3 The steel cable and steel-wood composite structural system includes wooden columns 2, column base embedded parts 3, roof timber frame 4, steel ring beam 5, and fixing components 6. In this embodiment, the wooden columns 2 and the roof timber frame 4 are spliced ​​together with wooden components, all of which are made of glued laminated timber. Since the construction area of ​​this structural system is surrounded by a concrete building 1, it is impossible to provide space for a crane indoors; therefore, the crane is set up on the outer perimeter of the concrete building 1, and the lifting range of the crane covers the construction area of ​​the structural system of this application.

[0044] Reference Figure 3 , Figure 4 The wooden column 2 includes several arc-shaped wooden columns 21 and column beams 22. The wooden column 21 includes a first end 7 and a second end 8. The first end 7 of the wooden column 21 is fixedly connected to the column base embedded part 3, and the second end 8 of the wooden column 21 is fixedly connected to the roof wooden frame 4.

[0045] Referring to section 4, several wooden pillars 21 are arranged in a ring at intervals, with the openings of the wooden pillars 21 facing away from the central axis of the wooden pillar 2. (Referring to...) Figure 4 and Figure 5 A first column ring 9 is formed by the first ends 7 of several wooden columns 21, and a second column ring 10 is formed by the second ends 8 of several wooden columns 21. In this embodiment, the area of ​​the second column ring 10 is larger than the area of ​​the first column ring 9. By splicing several arc-shaped wooden columns 21 to form a wooden column body 2, a larger area first column ring 9 is formed at the bottom of the wooden column body 2, thereby improving the stability of the connection between the wooden column body 2 and the ground. At the same time, a larger area second column ring 10 is formed at the top of the wooden column body 2, so that the upper part of the structural system has a large hollow area, thereby improving the permeability of the middle part of the structural system and improving the overall effect of the building.

[0046] Reference Figure 3 and Figure 4Several column beams 22 are arranged between adjacent wooden columns 21, and the ends of the column beams 22 are fixedly connected to the wooden columns 21 by bolts. This further improves the rigidity and load-bearing capacity of the wooden column structure 2.

[0047] Reference Figure 4 and Figure 5 The wooden column 2 also includes column connectors 23 and column steel cables 24. Several column connectors 23 are provided, and these connectors 23 are fixedly connected to the wooden column 21, with the connectors 23 positioned on both sides of the column beam 22. The column steel cables 24 are used to connect the column connectors 23 on adjacent wooden columns 21. The column connectors 23 are fixed to the wooden column 21, and after the two ends of the column steel cables 24 are connected to the column connectors 23 of adjacent wooden columns 21, the connection strength between adjacent wooden columns 21 is further reinforced by the column steel cables 24, thereby improving the stability and load-bearing capacity of the wooden column 2.

[0048] Reference Figure 4 and Figure 6 The column base embedded part 3 is used for fixed connection with the ground; one end of the wooden column 2 is fixedly connected to the column base embedded part 3. In this embodiment, the column base embedded part 3 includes a flat steel plate 31 and two vertically arranged vertical steel plates 32. The flat steel plate 31 and the vertical steel plates 32 can be welded and fixed, or they can be integrally cast. The flat steel plate 31 and part of the vertical steel plates 32 are buried in the ground. The bottom of the first end 7 of the wooden column 21 is provided with a column base groove 211 for inserting the vertical steel plates 32; both the vertical steel plates 32 and the wooden column 21 are provided with through holes for bolts to pass through (not shown in the figure), and the embedded part is fixedly connected to the wooden column 21 by bolts.

[0049] Reference Figure 2 , Figure 5 and Figure 9 The upper part of the wooden column 2 is fixedly connected to the roof frame 4. The roof frame 4 has a hollow inner ring in the middle, and the outer ring of the roof frame 4 is fixedly connected to the concrete building body 1. In this embodiment, the height of the inner ring of the roof frame 4 from the ground is greater than the height of the outer ring from the ground. The roof frame 4 is spliced ​​from multiple main wooden beams 41, wooden ring beams 42, and wooden secondary beams 43. Several main wooden beams 41 are arranged radially, and wooden ring beams 42 are arranged between adjacent main wooden beams 41, and several wooden ring beams 42 surround to form a ring structure. Wooden secondary beams 43 are arranged between the main wooden beams 41 and the wooden ring beams 42 to improve the structural strength of the roof frame 4. In this embodiment, the connection between the main wooden beams 41 and the wooden ring beams 42, the connection between the secondary wooden beams 43 and the main wooden beams 41, and the connection between the secondary wooden beams 43 and the wooden ring beams 42 are all bolted.

[0050] Reference Figure 7The beam-column connection nodes between the wooden column 2 and the roof frame 4 are arranged around the inner ring; the steel ring beam 5 is set in the inner ring and is fixedly connected to the roof frame 4. The fixing component 6 is set inside the steel ring beam 5 and is fixedly connected to the steel ring beam 5. By setting the steel ring beam 5 in the inner ring of the roof frame 4, a hollow area is created in the middle of the roof frame 4, thereby improving the permeability of the connection area between the roof frame 4 and the wooden column 2.

[0051] Reference Figure 5 and Figure 7 The fixing component 6 includes a steel connector 61, several upper chord steel cables 62 and lower chord steel cables 63. One end of the upper chord steel cable 62 is fixedly connected to the steel ring beam 5, and the other end of the upper chord steel cable 62 is fixedly connected to the steel connector 61. Several upper chord steel cables 62 are arranged around the steel connector 61.

[0052] Reference Figure 7 and Figure 8 Both ends of the lower chord steel cable 63 are fixedly connected to the steel ring beam 5. The bottom of the steel connector 61 is provided with an installation hole 611 for the lower chord steel cable 63 to pass through; several lower chord steel strands are arranged in an alternating manner.

[0053] Reference Figure 8 The steel connector 61 is connected to the steel ring beam 5 via several upper chord steel cables 62 and lower chord steel cables 63. Through the coordinated action of the fixing component 6 and the steel ring beam 5, the roof frame 4 structure can be stably supported. This reduces the obstruction of the view from the ground when people look up at the roof frame 4, improving the viewing experience. Simultaneously, sunlight can penetrate through the gap between the roof frame 4 and the wooden column 2 to reach the bottom of the structure, further enhancing the building's aesthetics. The bottom of the steel connector 61 features a through-type lower chord steel cable 63. This enhances the support effect of the fixing component 6 on the steel ring beam 5 and the roof frame 4. Furthermore, the through-type lower chord steel cable 63 reduces the risk of the central steel connector 61 falling due to cable creep of the upper chord steel cables 62, helping to maintain the tautness of the roof membrane structure and improving the building's aesthetics.

[0054] Reference Figure 8 The steel connector 61 includes a cylindrical body 612 and a protrusion 613; the protrusion 613 is located on the side of the cylindrical body 612 away from the wooden column 2, and the cylindrical body 612 is fixedly connected to the protrusion 613. The cylindrical body 612 is a frame structure made of steel. The distance from the protrusion 613 to the wooden column 2 is greater than the distance from the steel ring beam 5 to the wooden column 2. The protrusion 613 in the middle of the steel cable can improve the drainage performance of the roof, allowing water on the roof to flow along the roof slope to the surrounding areas, thereby reducing the occurrence of water accumulation on the roof.

[0055] Reference Figure 5 , Figure 9 and Figure 10 The roof frame 4 and the steel ring beam 5 are connected by wooden structural connectors 44. The main beams 41 and secondary beams 43 of the roof frame 4 have recessed grooves 11 for inserting the wooden structural connectors 44. All the main beams 41, secondary beams 43, and wooden structural connectors 44 of the roof frame 4 have through holes for steel pins to pass through. The through holes of the roof frame 4 are not shown in the figure. After the wooden beams and wooden structural connectors 44 are assembled, the entire assembly is hoisted to the marked position on the steel ring beam 5; after repeatedly confirming the position, the wooden structural connectors 44 are welded and fixed to the steel ring beam 5.

[0056] Reference Figure 7 and Figure 11 The structural system of this application also includes beam-column connectors 45, which are used to connect the wooden columns 2 and the roof frame 4.

[0057] Reference Figure 11 and Figure 12 The beam-column connector 45 includes a base plate 451, a sleeve 452, several column ear plates 453, and several beam ear plates 454. The sleeve 452 and the column ear plates 453 are located on both sides of the base plate 451, and the sleeve 452 is fixedly connected to the base plate 451, and the column ear plates 453 are fixedly connected to the sleeve 452.

The roof frame 4 and the wooden column 21 are fixedly connected by beam-column connector 45, which improves the connection strength between the roof frame 4 and the wooden column 2 and enhances the stability of the structural system.

[0058] Reference Figure 2 and Figure 14 It also includes a roof embedded part 14, which is used to connect the roof wooden frame 4 and the concrete building body 1. The roof embedded part 14 is embedded in the concrete building body 1, and the roof embedded part 14 is fixedly connected to the roof wooden frame 4. The wooden structure connector 44 is a steel plate with through holes. In this embodiment, the roof wooden frame 4 and the roof embedded part 14 are fixedly connected by the wooden structure connector 44. After the roof wooden frame 4 and the wooden structure connector 44 are assembled, the wooden structure connector 44 is welded to the embedded part. The roof wooden frame 4 is connected to the concrete building body 1 through the roof embedded part 14, so that the concrete building body 1 provides effective support for the roof wooden frame 4 along the outer periphery of the roof wooden frame 4, thereby further improving the stability of the roof wooden frame 4.
