Description

Technical Field

[0001] This application relates to the field of bridge technology, and more particularly to a truss-type bridge and its structure. Background Technology

[0002] Connecting bridges are frequently encountered in recent building structural systems. In related technologies, for connecting bridges with small spans and low requirements for overall connection stiffness, a large-span steel beam structural system can be adopted. For connecting bridges with large spans and high requirements for overall connection stiffness, a space truss structural system can be adopted.

[0003] In addition to their function as transportation routes, connecting bridges, especially those with larger architectural spaces, also serve functions such as offices, cultural spaces, and commercial spaces. In other words, these connecting bridges include architectural spaces with office, cultural, and commercial functions. For connecting bridges employing a space truss structural system, that is, truss-type connecting bridges, the exterior facades of their functional spaces typically feature diagonal members due to the truss structure. However, a problem arises: these diagonal members can negatively impact the aesthetics of the connecting bridge's facade, ventilation through windows, the layout of interior functions, and the view from the outside. Summary of the Invention

[0004] To address the aforementioned shortcomings in related technologies, this application provides a truss-type connecting bridge and building to solve the problem that diagonal members in related technologies have adverse effects on the aesthetics of the bridge's facade, ventilation of the facade windows, interior functional layout of the building, and landscape viewing.

[0005] To address the aforementioned technical problems, in a first aspect, this application provides a truss-type connecting bridge, which includes:

[0006] A truss, the two ends of which are rigidly connected to the main body of the building structure along its length;

[0007] The functional floors are arranged at least one level along the vertical direction, and the functional floors are arranged directly below the truss along the vertical direction, with the length direction of the functional floors being parallel to the length direction of the truss.

[0008] Two sets of suspended columns, each set comprising multiple suspended columns spaced apart along the length of the truss, each suspended column extending vertically along its length. The two sets of suspended columns are respectively connected to both ends of the width direction of the truss and both ends of the width direction of the functional floor. The truss, at least one functional floor, and the two sets of suspended columns together enclose at least one architectural functional space, which is used to communicate with at least one floor space of the main building structure.

[0009] In one possible implementation of the first aspect, the functional floor is provided as one floor, and the truss, the functional floor and the two sets of hanging columns together enclose a building functional space.

[0010] In one possible implementation of the first aspect, the truss includes a lower chord for being disposed in the first building floor level that is flush with the main body of the ground-mounted building structure in the vertical direction;

[0011] The functional floor is used to set up a third functional floor that is vertically flush with the floor slab of the first building and one floor below it.

[0012] In one possible implementation of the first aspect, the functional floors are arranged in two layers along the vertical interval, and the truss, the two functional floors, and the two rows of hanging columns together enclose two building functional spaces arranged along the vertical interval.

[0013] In one possible implementation of the first aspect, the truss includes a lower chord for being disposed in the first building floor level that is flush with the main body of the ground-mounted building structure in the vertical direction;

[0014] The upper functional floor of the two functional floors is used to set up a second building floor that is vertically lower than the first building floor and also to set up a third building floor that is vertically higher than the second building floor; the lower functional floor of the two functional floors is used to set up a fourth building floor that is vertically flush with the third building floor.

[0015] In one possible implementation of the first aspect, the truss includes a lower chord and an upper chord located directly above the lower chord, the upper chord being configured to be lower than or flush with the parapet wall of the main body of the ground-mounted building structure.

[0016] In one possible implementation of the first aspect, both ends of the functional floor along its length are rigidly connected to the main body of the ground-mounted building structure.

[0017] In one possible implementation of the first aspect, the functional floor includes a functional floor horizontal support frame and a functional floor slab disposed on top of the functional floor horizontal support frame. The functional floor horizontal support frame is connected to the hanging column to connect the functional floor and the hanging column. The functional floor slab is a steel truss floor deck.

[0018] Secondly, this application also provides a building comprising:

[0019] The main building structure includes side walls and multiple floor slabs arranged vertically at intervals, with two adjacent floor slabs and the side walls together forming a floor space.

[0020] At least one of the truss-type bridges described in any of the first aspects.

[0021] In a possible implementation of the second aspect, the truss-type bridge includes a first truss-type bridge and a second truss-type bridge.

[0022] The first truss-type connecting bridge includes one functional floor, and the second truss-type connecting bridge includes two functional floors arranged at intervals along the vertical direction.

[0023] Compared with related technologies, this application has at least the following beneficial effects:

[0024] In this application, since the two ends of the truss along its length are rigidly connected to the main structure of the building, and since the two sets of hanging columns are respectively connected to the two ends of the truss along its width and the two ends of the functional floor along its width, the truss-type bridge in this application can form an upper-supported and lower-suspended structure. Specifically, the truss is the main load-bearing component of the truss-type bridge, and the functional floor is suspended below the truss by the two sets of hanging columns. This not only makes the force distribution of the truss-type bridge structure in this application clear, but also, since each hanging column extending vertically along its length is subjected to the vertical gravity of the functional floor, each hanging column is equivalent to a tie rod, that is, the force direction of each hanging column is parallel to its length direction. This can give full play to the tensile advantage of the steel of the hanging column, which is relatively beneficial to ensuring the stability of the hanging column structure compared with the compression column, and is beneficial to giving full play to the structural strength of the hanging column, thereby ensuring the stability and structural strength of the truss-type bridge structure.

[0025] Since the truss, functional floors, and two sets of suspended columns together enclose a building functional space that connects to at least one floor of the main building structure, this truss-type bridge can not only have building functional spaces for office, cultural, and commercial functions, but also, because the suspended columns extending vertically along the length direction are set on the exterior facade of the building functional space, compared with the diagonal members in related technologies, the suspended columns extending vertically along the length direction can not only ensure the stability and structural strength of the truss-type bridge structure, but also help to ensure the aesthetics of the bridge's exterior facade, facilitate the functional layout of the building's interior, and will not interfere with the movement of the windows on the exterior facade. It is also conducive to facilitating the opening and ventilation of the exterior facade and the viewing of the landscape. In other words, the suspended columns in this application will not have an adverse impact on the aesthetics of the bridge's exterior facade, the opening and ventilation of the exterior facade, the functional layout of the building's interior, or the viewing of the landscape.

[0052] As described in the background section of this application, in related technologies, connecting bridges are frequently encountered in building structural systems in recent years. For connecting bridges with small spans and low requirements for overall connection stiffness, a large-span steel beam structural system can be adopted. For connecting bridges with large spans and high requirements for overall connection stiffness, a space truss structural system can be adopted.

[0053] In addition to their function as transportation routes, connecting bridges, especially those with larger architectural spaces, also serve functions such as offices, cultural spaces, and commercial spaces. In other words, these connecting bridges include architectural spaces with office, cultural, and commercial functions. For connecting bridges employing a space truss structural system, that is, truss-type connecting bridges, the exterior facades of their functional spaces typically feature diagonal members due to the truss structure. However, a problem arises: these diagonal members can negatively impact the aesthetics of the connecting bridge's facade, ventilation through windows, the layout of interior functions, and the view from the outside.

[0054] Example 1

[0055] In view of the above-mentioned problems, this application provides a truss-type connecting bridge to solve the problem that the diagonal members in the related technology have an adverse effect on the aesthetics of the bridge facade, ventilation of the facade windows, interior functional layout and landscape viewing.

[0056] The technical solution of this application will be further described below with reference to specific embodiments and accompanying drawings:

[0057] like Figure 1 and Figure 2 As shown, the truss-type connecting bridge 10 includes a truss 1, functional floors 2, and two sets of hanging columns 3. The truss 1 extends along its length direction (…). Figure 2 The two ends of the X-axis direction are used to rigidly connect with the main building structure 20, and the functional floor 2 is along the vertical ( Figure 2 At least one layer is provided at intervals along the Z-axis direction, and the functional floors 2 are arranged vertically at intervals directly below the truss 1, with the functional floors 2 extending along their length direction (…). Figure 2 The X-axis direction in the figure is parallel to the length direction of truss 1.

[0058] Each set of hanging columns 3 includes multiple hanging columns 3 spaced apart along the length direction of the truss 1, and the length direction of each hanging column 3 ( Figure 2 The Z-axis direction of the truss 1 extends vertically, and the two sets of hanging columns 3 extend vertically along the width direction of the truss 1, respectively. Figure 3 The two ends of the Y-axis direction and the width direction of functional floor 2 (in the middle) Figure 5The truss 1, at least one functional floor 2, and two sets of hanging columns 3 are connected at both ends in the Y-axis direction. Together, they form at least one building functional space 4, which is used to connect with at least one floor space 201 of the main building structure 20.

[0059] In this application, since the two ends of the truss 1 in the length direction are rigidly connected to the main structure 20 of the building, and since the two sets of hanging columns 3 are respectively connected to the two ends of the truss 1 in the width direction and the two ends of the functional floor 2 in the width direction, the truss bridge 10 in this application can form an upper-supported and lower-suspended structure. Specifically, the truss 1 is the main load-bearing component of the truss bridge 10, and the functional floor 2 is suspended below the truss 1 by the two sets of hanging columns 3. This not only makes the stress of the truss bridge 10 structure in this application clear, but also, since each hanging column 3 extending vertically in the length direction is subjected to the vertical gravity of the functional floor 2, each hanging column 3 is equivalent to a tie rod, that is, the force direction of each hanging column 3 is parallel to its length direction. This can give full play to the tensile advantage of the steel of the hanging column 3, which is relatively beneficial to ensuring the stability of the hanging column 3 structure compared with the compression column, and is beneficial to giving full play to the structural strength of the hanging column 3, thereby ensuring the stability and structural strength of the truss bridge 10 structure.

[0060] Since the truss 1, the functional floor 2, and the two sets of hanging columns 3 together enclose a building functional space 4 that is connected to at least one floor space 201 of the main building structure 20, the truss-type bridge 10 can not only have building functional spaces 4 with functions such as office, culture, and commerce, but also, since the hanging columns 3 extending vertically along the length direction are set on the exterior facade of the building functional space 4, compared with the diagonal members in related technologies, the hanging columns 3 extending vertically along the length direction can not only ensure the stability and structural strength of the truss-type bridge 10 structure, but also help to ensure the aesthetics of the exterior facade of the truss-type bridge 10, facilitate the functional layout of the building interior, and will not interfere with the movement of the windows on the exterior facade, which is conducive to facilitating the opening and ventilation of the exterior facade and the viewing of the landscape. That is, the hanging columns 3 in this application will not have an adverse effect on the aesthetics of the bridge facade, the opening and ventilation of the exterior facade, the functional layout of the building interior, and the viewing of the landscape.

[0061] Regarding the number of hanging columns 3 in each group of hanging columns 3, specifically, in this embodiment, each group of hanging columns 3 includes seven hanging columns 3 spaced apart along the length direction of the truss 1. Since the span of the truss bridge 10 in this embodiment is 59.6 meters, the number of hanging columns 3 in each group of hanging columns 3 is relatively small. This number of hanging columns 3 not only ensures the stability and strength of the functional floor 2 suspension, but also reduces the weight of the truss bridge 10 to a certain extent, which is beneficial to the construction of the truss bridge 10.

[0062] In other embodiments, each group of hanging columns 3 may also include five, six, eight or more hanging columns 3. The number of hanging columns 3 is set flexibly and can be specifically determined according to actual design requirements.

[0063] Regarding the number of functional floors 2, specifically, in this embodiment, as follows: Figure 1 and Figure 2 As shown, the functional floor 2 has one floor, and the truss 1, the first floor 2, and the two sets of hanging columns 3 together form a building functional space 4.

[0064] This arrangement, to a certain extent, not only satisfies the functional needs of office, culture, and commerce through a single building functional space 4, but also simplifies the structural composition of the truss-type connecting bridge 10, which is conducive to the construction of the truss-type connecting bridge 10.

[0065] Furthermore, such as Figure 1 and Figure 2 As shown, the truss 1 includes a lower chord 11, which is used to be set in the first building floor 202 that is vertically flush with the main building structure 20. The functional floor 2 is used to be set in the third building floor 203 that is vertically flush with the floor below the first building floor 202.

[0066] This arrangement allows the functional space 4 to have a greater vertical height, thereby increasing the overall size of the functional space 4. This expands the activity space for offices, cultural activities, and commercial activities within the functional space 4, facilitating these activities. Positioning the functional floor 2 vertically flush with the third building floor 203 avoids the need for a staircase between them, simplifying the structural arrangement between the two floors and facilitating the construction of the truss-type connecting bridge 10.

[0067] In another embodiment, the functional floor 2 is set up on the second building floor 204, which is vertically flush with the floor 202 of the first building. This arrangement not only ensures that the building's functional space 4 has sufficient space for office, cultural, and commercial activities, but also reduces the overall vertical height of the truss-type bridge 10, which facilitates the installation of the truss-type bridge 10 on the main building structure 20.

[0068] In other embodiments, the functional floor 2 may be positioned vertically below or above the third building floor 203. Alternatively, the functional floor 2 may be positioned below, above, or level with other building floor slabs that are different from the second and third building floor slabs 204 and 203. The positional relationship between the functional floor 2 and the building floor slabs is quite flexible and can be specifically determined according to actual needs.

[0069] like Figure 1 and Figure 2 As shown, truss 1 includes a lower chord 11 and an upper chord 12 located directly above the lower chord 11. The upper chord 12 is used to set up a parapet wall (not marked in the figure) that is lower than or flush with the main body of the building structure 20.

[0070] This design avoids the parapet wall of the truss-type connecting bridge 10 being higher than the main building structure 20, thus ensuring the aesthetic appearance of the entire building.

[0071] Specifically, in this embodiment, such as Figure 1 and Figure 2 As shown, the upper chord 12 of the truss is set flush with the parapet wall of the main building structure 20. This arrangement ensures that the truss-type bridge 10 has a higher installation height relative to the main building structure 20, thereby increasing the passage space under the truss-type bridge 10 and facilitating passage under the truss-type bridge 10.

[0072] In other embodiments, the upper chord 12 of the truss can also be set higher than the parapet wall of the main building structure 20. This arrangement can further increase the setting height of the truss-type bridge 10 relative to the main building structure 20, thereby further increasing the passage space under the truss-type bridge 10 and facilitating passage under the truss-type bridge 10.

[0073] Specifically, for the upper chord 12 of the truss, as follows: Figure 3 As shown, the truss upper chord 12 is composed of an upper chord horizontal support frame, which includes an upper chord crossbeam 121 extending along the length direction of the truss 1, an upper chord longitudinal beam 122 perpendicularly connected to the upper chord crossbeam 121, and an upper chord diagonal member 123 connecting two adjacent upper chord crossbeams 121. The truss upper chord 12 is connected to the main building structure 20 by connecting the upper chord crossbeam 121 to the reserved steel beam segment 5.

[0074] This design not only ensures the structural strength of the upper chord 12 and the connection strength between the upper chord 12 and the main building structure 20, but also reduces the weight of the upper chord 12, thereby reducing the overall weight of the truss 1 and facilitating its construction on the main building structure 20. Furthermore, the upper chord longitudinal beam 122, connected to the upper chord crossbeam 121, also addresses the lateral stability of the upper chord 12, contributing to its lateral stability.

[0075] In other embodiments, the truss top chord 12 may also include a top chord horizontal support frame and a roof panel disposed on top of the top chord horizontal support frame. This arrangement allows for the formation of a usable passageway on the truss top chord 12, which can be used not only to arrange various pipes but also as a passageway, thereby further enhancing the practicality of the truss top chord 12.

[0076] Specifically, for the lower chord 11 of the truss, as follows: Figure 2 and Figure 4 As shown, the lower chord 11 of the truss includes a lower chord horizontal support frame 111 and a roof panel 112 disposed on top of the lower chord horizontal support frame 111. The roof panel 112 is a steel truss floor slab. The lower chord horizontal support frame 111 includes a lower chord crossbeam 1111 extending along the length direction of the truss 1, a lower chord longitudinal beam 1112 perpendicularly connected to the lower chord crossbeam 1111, and a lower chord diagonal member 1113 connected to both. The lower chord 11 is also connected to the main building structure 20 by the connection between the lower chord crossbeam 1111 and the reserved steel beam segment 5.

[0077] A roof panel 112 is installed on the top of the lower chord horizontal support frame 111. In addition to providing shelter from wind and rain for the building functional space 4 below, it also forms a passage between the lower chord 11 and the upper chord 12 of the truss. This passage can be used to arrange various pipes and also as a passageway, which helps to further enhance the practicality of the truss 1.

[0078] The lower chord horizontal support frame 111 not only ensures the structural strength of the lower chord 11 and the connection strength between the lower chord 11 and the main body of the building structure 20, but also reduces the weight of the lower chord 11, thereby further reducing the weight of the entire truss 1, which is conducive to facilitating the construction of the truss 1 on the main body of the building structure 20.

[0079] Because steel truss floor decking is relatively lightweight, using steel truss floor decking for roof panel 112 not only further reduces the weight of the lower chord 11 of the truss, but also facilitates the handling, stacking, and installation of roof panel 112. In addition, since steel truss floor decking does not require casting on the truss 1 using molds, it further facilitates the installation of roof panel 112 on the truss 1.

[0080] The lateral stability problem of the lower chord 11 can be solved by the lower chord longitudinal beam 1112 connected to the lower chord crossbeam 1111 and the roof panel 112, which helps to ensure the lateral stability of the lower chord 11.

[0081] In other embodiments, the roof panel 112 can also be a reinforced concrete slab. This arrangement can ensure the structural strength of the roof panel 112, and thus the structural strength of the lower chord 11 of the truss.

[0082] In other embodiments, for the upper chord 12 and the lower chord 11 of the truss, both the upper chord beam 121 and the lower chord beam 1111 can be beams integrally formed with the beams in the main building structure 20. This arrangement can further ensure the connection strength between the upper chord 12 and the lower chord 11 of the truss and the main building structure 20, and thus also further ensure the connection strength between the truss 1 and the main building structure 20.

[0083] In addition, in this embodiment, the truss 1 is a Warren truss. The truss 1 also includes a connection node 13 disposed on the lower chord 11 and the upper chord 12 of the truss, and a diagonal web member 14 whose two ends are respectively connected to the connection node 13 on the lower chord 11 and the upper chord 12 of the truss. The hanging column 3 is connected to the truss 1 by connecting to the connection node 13 on the lower chord 11 of the truss.

[0084] Because the stress distribution of the Warren truss is relatively uniform, truss 1 can effectively bear and distribute the load. Furthermore, the Warren truss has a simple structure and is easy to construct, thus simplifying the structure of truss 1 and facilitating its construction. In addition, the connection node 13 not only ensures the connection strength between the hanging column 3 and truss 1 but also facilitates the connection between them.

[0085] In other embodiments, truss 1 can also be a Pratt truss or a Fink truss, etc. The type of truss 1 is more flexible and can be determined according to specific actual needs.

[0086] like Figure 1 and Figure 2 As shown, both ends of the functional floor 2 along its length are used to rigidly connect to the main building structure 20.

[0087] This configuration allows the functional floor 2 to be supported by the main building structure 20, which in turn supports the entire truss bridge 10, thus further ensuring the stability of the truss bridge 10 on the main building structure 20.

[0088] Specifically, such as Figure 2 As shown, functional floor 2 is rigidly connected to the reserved steel beam segment 5 on the main building structure 20. Other reserved steel beam segments 5 on the main building structure 20 that are not rigidly connected to functional floor 2 need to be removed. By setting the reserved steel beam segment 5 to rigidly connect functional floor 2, not only is the rigid connection of functional floor 2 to the main building structure 20 facilitated, but the reliability of the rigid connection of functional floor 2 to the main building structure 20 is also guaranteed.

[0089] In other embodiments, the functional floor 2 can also be rigidly connected to the main building structure 20 by being rigidly connected to the building floor slab. This arrangement not only ensures the reliability of the rigid connection between the functional floor 2 and the main building structure 20, but also simplifies the structural setup on the main building structure 20 by eliminating the need for pre-reserved steel beam segments 5, thus facilitating the construction of the main building structure 20.

[0090] In another embodiment, the functional floor 2 is suspended at both ends along its length, meaning it is not rigidly connected to the main building structure 20. In this case, the functional floor 2 and the third building floor 203 can be joined together. This arrangement not only simplifies the structural arrangement between the functional floor 2 and the main building structure 20, facilitating their construction, but also ensures safe passage for people between the floor space 201 and the building's functional space 4.

[0091] like Figure 5 As shown, the functional floor 2 includes a functional floor horizontal support frame 21 and a functional floor slab 22 set on top of the functional floor horizontal support frame 21. The functional floor horizontal support frame 21 is connected to the hanging column 3 so that the functional floor 2 and the hanging column 3 are connected. The functional floor slab 22 is a steel truss floor deck.

[0092] In this embodiment, the structural composition of the functional floor horizontal support frame 21 is the same as that of the lower chord horizontal support frame 111, and will not be described in detail here. The functional floor horizontal support frame 21 can not only ensure the structural strength of the functional floor 2, but also reduce the weight of the functional floor 2, thereby further reducing the weight of the entire truss bridge 10, which is conducive to further facilitating the construction of the truss bridge 10 on the main body of the ground building structure 20.

[0093] Because steel truss floor decking is relatively lightweight, using steel truss floor decking for functional floor slab 22 not only further reduces the weight of functional floor 2, but also facilitates the handling, stacking, and installation of functional floor decking 22. Furthermore, since steel truss floor decking does not require casting using molds on functional floor 2, it further simplifies the installation of functional floor decking 22 on functional floor 2.

[0094] The structure of the functional floor horizontal support frame 21 and the functional floor slab 22 can solve the lateral stability problem of the functional floor 2, which is conducive to ensuring the lateral stability of the functional floor 2.

[0095] In other embodiments, the functional floor slab 22 can also be a reinforced concrete slab. This configuration can ensure the structural strength of the functional floor slab 22, and thus ensure the structural strength of the functional floor 2.

[0096] In other embodiments, the structural composition of the functional floor horizontal support frame 21 may differ from that of the lower chord horizontal support frame 111; that is, the functional floor horizontal support frame 21 may only include crossbeams and longitudinal beams. This configuration simplifies the structure of the functional floor horizontal support frame 21, facilitates its construction, and reduces its weight.

[0097] Example 2

[0098] This application also provides a truss-type connecting bridge 10 that differs from Embodiment 1. Specifically, the difference between this embodiment and Embodiment 1 is as follows:

[0099] like Figure 6 As shown, the functional floor 2 is arranged with two layers at vertical intervals. The truss 1, the two functional floors 2 and the two rows of hanging columns 3 together enclose two building functional spaces 4 arranged at vertical intervals.

[0100] This arrangement increases the number of functional spaces 4 in the truss-type bridge 10, thereby further expanding the activity space for office, cultural, and commercial activities in the truss-type bridge 10. This facilitates office, cultural, and commercial activities in the truss-type bridge 10 and also enables full utilization of the space.

[0101] Regarding the positional relationship between the two functional floors 2 and the corresponding building floor slabs, this application provides only one implementation method. Other implementation methods will not be described in detail in this application.

[0102] Specifically, such as Figure 6As shown, the truss 1 includes a lower chord 11, which is used to be installed in the first building floor 202 that is vertically flush with the main building structure 20.

[0103] The upper functional floor 2 of the two aforementioned functional floors 2 is used to be set up in the second building floor 204, which is vertically lower than the first building floor 202, and is also used to be set up in the third building floor 203, which is vertically higher than the second building floor 204. The lower functional floor 2 of the two functional floors 2 is used to be set up in the fourth building floor 205, which is vertically flush with the third building floor 203.

[0104] This configuration ensures that the upper building functional space 4 has sufficient vertical height while allowing the lower building functional space 4 to have greater vertical height. This enables the two building functional spaces 4 to meet different usage needs and further enhances the practicality of the truss-type connecting bridge 10.

[0105] Unlike Embodiment 1 and Embodiment 2, in other embodiments, as long as the height of the main building structure 20 is sufficient, the functional floors 2 can also be arranged with three, four or more floors at vertical intervals. The number of floors of the functional floors 2 is more flexible and can be specifically determined according to actual needs.

[0106] Example 3

[0107] This application also provides a building, such as Figure 1 and Figure 7 As shown, the building includes a ground-mounted main building structure 20 and at least one truss-type connecting bridge 10. The ground-mounted main building structure 20 includes side walls (not shown in the figure) and multiple building floor slabs arranged vertically at intervals. Two adjacent building floor slabs and side walls together enclose a floor space 201. The truss-type connecting bridge 10 has the same structure as any of the truss-type connecting bridges 10 in the above embodiments and can bring the same or similar beneficial effects. For details, please refer to the description in the above embodiments. This embodiment will not repeat it here.

[0108] In this application, since the two ends of the truss 1 in the length direction are rigidly connected to the main structure 20 of the building, and since the two sets of hanging columns 3 are respectively connected to the two ends of the truss 1 in the width direction and the two ends of the functional floor 2 in the width direction, the truss bridge 10 in this application can form an upper-supported and lower-suspended structure. Specifically, the truss 1 is the main load-bearing component of the truss bridge 10, and the functional floor 2 is suspended below the truss 1 by the two sets of hanging columns 3. This not only makes the stress of the truss bridge 10 structure in this application clear, but also, since each hanging column 3 extending vertically in the length direction is subjected to the vertical gravity of the functional floor 2, each hanging column 3 is equivalent to a tie rod, that is, the force direction of each hanging column 3 is parallel to its length direction. This can give full play to the tensile advantage of the steel of the hanging column 3, which is relatively beneficial to ensuring the stability of the hanging column 3 structure compared with the compression column, and is beneficial to giving full play to the structural strength of the hanging column 3, thereby ensuring the stability and structural strength of the truss bridge 10 structure.

[0109] Since the truss 1, the functional floor 2, and the two sets of hanging columns 3 together enclose a building functional space 4 that is connected to at least one floor space 201 of the main building structure 20, the truss-type bridge 10 can not only have building functional spaces 4 with functions such as office, culture, and commerce, but also, since the hanging columns 3 extending vertically along the length direction are set on the exterior facade of the building functional space 4, compared with the diagonal members in related technologies, the hanging columns 3 extending vertically along the length direction can not only ensure the stability and structural strength of the truss-type bridge 10 structure, but also help to ensure the aesthetics of the exterior facade of the truss-type bridge 10, facilitate the functional layout of the building interior, and will not interfere with the movement of the windows on the exterior facade, which is conducive to facilitating the opening and ventilation of the exterior facade and the viewing of the landscape. That is, the hanging columns 3 in this application will not have an adverse effect on the aesthetics of the bridge facade, the opening and ventilation of the exterior facade, the functional layout of the building interior, and the viewing of the landscape.

[0110] Furthermore, such as Figure 7 As shown, the truss-type connecting bridge 10 includes a first truss-type connecting bridge 101 and a second truss-type connecting bridge 102. The first truss-type connecting bridge 101 includes one functional floor 2, and the second truss-type connecting bridge 102 includes two functional floors 2 arranged vertically at intervals.

[0111] This arrangement enriches the structure of the truss-type connecting bridge 10 in the building. At the same time, the truss-type connecting bridge 10 with different structures can not only meet different usage needs, but also make full use of the space in different locations of the building.

[0112] Regarding the structure of the first truss-type connecting bridge 101 and the second truss-type connecting bridge 102, this application embodiment provides only one implementation method. Other implementation methods will not be described in detail in this application embodiment.

[0113] Specifically, in this embodiment, the building includes only two truss-type connecting bridges 10, namely a first truss-type connecting bridge 101 and a second truss-type connecting bridge 102. The first truss-type connecting bridge 101 is exactly the same as the truss-type connecting bridge 10 in Embodiment 1, and the second truss-type connecting bridge 102 is exactly the same as the truss-type connecting bridge 10 in Embodiment 2. Of course, the beneficial effects of both the first truss-type connecting bridge 101 and the second truss-type connecting bridge 102 are the same as those of the corresponding truss-type connecting bridges 10 in Embodiments 1 and 2, respectively, and will not be elaborated upon here.

[0114] In other embodiments, the building may include a first truss bridge 101 or a second truss bridge 102. Of course, the building may also include other truss bridges 10 that are different from the first truss bridge 101 and the second truss bridge 102. The structural selection of the truss bridge 10 in the building is relatively flexible and can be specifically determined according to the actual needs.

[0115] In other embodiments, the building may also include one, three or more truss-type connecting bridges 10. The number of truss-type connecting bridges 10 in the building is flexible and can be determined according to the specific needs.

[0116] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
