Description

Technical Field

[0001] This invention belongs to the field of architectural and bridge engineering design technology, and in particular relates to a cable-stayed high-altitude sightseeing corridor and its construction method. Background Technology

[0002] Domestic and international urban practices have shown that the construction of elevated walkway systems can effectively solve problems such as traffic congestion, space shortages, and fire evacuation in urban centers to a certain extent. In recent years, elevated walkways have also served to promote urban sightseeing and provide opportunities for high-altitude strolls.

[0003] The key issue with sky bridges lies in how they connect to the main structure. Because the sky bridge and the connected towers influence each other, especially under the influence of earthquakes and wind, deformation and stress are quite complex. Therefore, choosing between a strong or weak connection becomes the primary issue. A strong connection refers to a method where both ends of the connecting structure are fixedly connected to the main structure, and relative movement between the connecting structure and the main structure is not allowed. A typical example of a strong connection is the new CCTV headquarters building, where the connecting structure is a cantilevered, rigid joint. Due to the mutual constraints and coordination between the connecting structure and the main structure, and their combined effects, the stress on both the connecting structure itself and the entire structure is complex with strong connections. Furthermore, the installation method for sky bridges with strong connections is often a whole-structure hoisting method in mid-air, which carries significant risks.

[0004] A weak connection refers to a sliding connection or an elastic connection equipped with viscous damping and limiting systems. One or both ends of the connection can experience relative displacement with the main structure, thus having a relatively small impact on the main structure. It primarily transmits its own weight and vertical seismic forces through supports. Typical examples of weak connections include the Petronas Twin Towers in Malaysia and the Beijing Modern MOMA. The span of elevated walkways with weak connections is generally small, which is not conducive to the development of tourism projects such as city sightseeing and skywalks.

[0005] Therefore, the present invention provides a high-safety, long-span aerial walkway to solve the above problems. Summary of the Invention

[0006] To overcome the shortcomings of the prior art, this invention provides a cable-stayed bridge-style high-altitude sightseeing corridor and its construction method, which innovatively combines the cable-stayed bridge structure with high-rise buildings, ensuring urban sightseeing and high-altitude walking while achieving a weak connection between the ultra-large span corridor structure and the main building.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A cable-stayed bridge-style high-altitude sightseeing corridor includes a cable-stayed bridge structure that horizontally connects two high-rise buildings. Spaces are reserved on the main beams on both sides of the cable-stayed bridge structure for elevator passages of the high-rise buildings to pass through. The elevator passages vertically connect the high-rise buildings and the cable-stayed bridge structure. A docking level is provided on the bridge deck of the cable-stayed bridge structure.

[0009] The high-rise building and the two tower legs of the cable-stayed bridge structure are fixedly connected by cantilever beams, and the two tower legs of the cable-stayed bridge structure are fixedly connected by tower crossbeams; the cable-stayed bridge structure does not have pile foundations, and the lower tower column of the cable-stayed bridge structure tower extends into the raft foundation of the high-rise building;

[0010] The anchorage zones at the ends of the cable-stayed beams of the side spans of the cable-stayed bridge are centrally located, and steel frames are provided at the ends of the cable-stayed beams of the side spans and at the top of the columns of the high-rise building structure.

[0011] A double-sided steel box girder is positioned at the center of the steel frame, and compression supports are respectively provided between the double-sided steel box girder and the upper and lower steel beams of the steel frame. During the installation phase, the double-sided steel box girder, under its own weight, causes the compression supports located below it to bear force, acting as positive and negative force supports; during the operation phase, the compression supports above the double-sided steel box girder bear force, acting as negative force supports.

[0012] Preferably, the steel frame includes steel columns on both sides, an upper steel beam and a lower steel beam fixedly connected to the steel columns on both sides, and the lower steel beam of the steel frame is embedded at the top of the building structural column; the steel columns on both sides of the steel frame extend downward into the building structural column respectively, and shear studs are provided on the outer side of the steel columns;

[0013] Preferably, the side span double-sided steel box girder is provided with corbels on both sides of the web plate, and the top surface of the corbels is flush with the top surface of the side span double-sided steel box girder; the top surfaces of the two corbels are respectively provided with jacks, and the compression bearings are replaced by lifting the jacks simultaneously.

[0014] Preferably, the main girder of the side span of the cable-stayed bridge adopts a variable-width side span double-sided steel box girder structure. The variable-width side span double-sided steel box girder structure includes two double-sided steel box girders and a transverse diaphragm beam located between them. The width between the two double-sided steel box girders of the side span is adjusted by the length of the transverse diaphragm beam set between the two double-sided steel box girders. Furthermore, the net distance between the reserved space between the double-sided box girders of the side span should be greater than the cross-sectional dimension of the elevator passage to facilitate the passage of the elevator.

[0015] Preferably, the lower tower column of the cable-stayed bridge tower is made of concrete, and the upper tower column is made of steel; the cantilever beam connected to the lower tower column of the concrete structure is a concrete beam, and the cantilever beam connected to the upper tower column of the steel structure is a steel beam; the lower tower column of the concrete structure extends into the raft foundation of the high-rise building.

[0016] Preferably, the side-to-mid span ratio of the cable-stayed bridge is less than 0.15, and the number of side-span cable stays does not exceed 2 sets.

[0017] Preferably, the cross-sectional area and bending section modulus of the cable-stayed bridge tower are reduced by about 1 / 4 to 1 / 3 compared with those of conventional bridge towers, which greatly reduces the amount of steel used in the steel tower.

[0018] Preferably, the high-rise building is equipped with two cantilever beams connected to the tower legs of the cable-stayed bridge every 4-5 floors.

[0019] This invention also provides a construction method for a cable-stayed high-altitude sightseeing corridor, comprising the following steps:

[0020] Step 1: Construct the raft foundation for high-rise buildings, and thicken the raft foundation in the area near the tower of the cable-stayed bridge.

[0021] Step 2: Construct the main structures of the high-rise buildings on both sides of the bridge. The construction of the cable-stayed bridge towers will lag behind the height of the high-rise buildings by two stories. The cable-stayed bridge towers will be installed using the same construction crane. When the tower height exceeds the design position of the cantilever beam, the cantilever beam will be installed.

[0022] Step 3: Once the building reaches a certain height, steel columns for the steel frame are pre-embedded in the structural columns, and construction continues until the building is topped out; after the building is topped out, construction of the cable-stayed bridge towers continues until the cable-stayed bridge towers are installed.

[0023] Step 4: Use a tower crane to install the side span double-sided steel box girder in sections, and reserve space for elevator access.

[0024] Step 5: Install the lower compression bearings of the double-sided steel box girders of the side span of the cable-stayed bridge, the double-sided steel box girders of the side span, and the upper compression bearings; weld the upper and lower steel beams of the steel frame onto the steel columns; install the cable stays of the side span.

[0025] Step Six: Use a bridge deck crane to lift the mid-span steel box girder segments one by one, and install the cable stays one by one until the mid-span steel box girder is closed; adjust the cable tension of the cable stays.

[0026] Step 7: Install elevators on the high-rise buildings on both sides; install bridge deck ancillary structures; complete the construction of the cable-stayed bridge-style high-altitude sightseeing corridor.

[0027] Preferably, in step one, the thickness of the raft foundation within a range of three times the tower leg around the cable-stayed bridge tower is increased; in step three, when the high-rise building is constructed to the designed height of the bottom of the steel column, steel columns with steel frames are pre-embedded in the building structural columns.

[0028] The beneficial effects of this invention are:

[0029] (1) The cable-stayed bridge-type high-altitude sightseeing corridor structure proposed in this invention innovatively combines the cable-stayed bridge structure with high-rise buildings, and is a new type of aerial corridor structure.

[0030] (2) In this invention, the cable-stayed bridge tower pier and the main body of the high-rise building share the building raft foundation, which eliminates the need for pile foundations, representing a significant technological breakthrough compared to conventional bridges.

[0031] (3) In this invention, the steel box girder of the connecting corridor is connected to the high-rise building by a vertical compression support, which is a weak connection. By setting the side and middle span cable stays, the weak connection between the ultra-large span connecting corridor structure and the main building is realized.

[0032] (4) In this invention, cantilever beams connected to the cable-stayed bridge towers are set at certain intervals in the building, which reduces the free length of the tower legs, that is, reduces the stress on the tower legs, thereby reducing the cross-sectional area of ​​the tower legs and reducing the cost.

[0033] (5) In this invention, steel brackets are set on both sides of the steel box girder. The compression support can be replaced by simultaneously lifting jacks on the steel brackets.

[0034] (6) In this invention, the elevator passage penetrates the bridge surface and a stop layer is set on the bridge surface, effectively connecting the building space and the bridge space, realizing the sightseeing attributes of the corridor, while also relieving the pressure of ground traffic.

[0035] (7) In this invention, two upper and lower compression supports are set between the steel frame and the double-sided steel box girder of the side span of the cable-stayed bridge to serve as negative reaction force supports.

[0036] (8) The construction method of the connecting corridor structure in this invention is the segmental lifting and assembly method, which has a light lifting weight and greatly improves construction safety.

[0037] (9) The installation of cable-stayed bridge towers uses a shared construction tower crane, which reduces the space occupied during construction and improves the utilization rate of construction machinery and equipment. Attached Figure Description

[0044] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art will understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0045] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0046] like Figures 1 to 5 As shown, the present invention provides a cable-stayed bridge-type high-altitude sightseeing corridor, including a cable-stayed bridge 2 structure that connects two high-rise buildings 1 140m apart. The cable-stayed bridge 2 structure horizontally connects the two high-rise buildings 1. Spaces are reserved on the two side span main beams 4 of the cable-stayed bridge 2 structure for elevator passages 3 of the high-rise buildings 1 to pass through. The elevator passages 3 of the two high-rise buildings 1 respectively penetrate the two side span main beams 4 of the cable-stayed bridge 2, and the elevator passages 3 vertically connect the high-rise buildings 1 and the cable-stayed bridge 2 structure. At the same time, a docking level is set on the bridge deck of the cable-stayed bridge 2 structure.

[0047] The main girder of cable-stayed bridge 2 consists of 7 segments of steel box girder at mid-span and segments of steel box girder in the side spans. To achieve vertical connection between high-rise building 1 and cable-stayed bridge 2, the main girder 4 of the side span of cable-stayed bridge 2 adopts a variable-width side span double-sided steel box girder 5 structure, with a reserved space for a building elevator passage 3 between the two side span double-sided box girders. The width of the variable-width side span double-sided steel box girder 5 can be adjusted by adjusting the length of the transverse diaphragm 6 connecting the two side span double-sided steel box girders; during construction, the net distance between the reserved space between the two side span double-sided box girders should be greater than the cross-sectional dimension of the elevator passage 3.

[0048] The anchorage zones 9 of the side span cable stays 8 and the beam ends of the cable stays 8 of the side span are centrally located. Steel frames 13 and compression bearings 14 are provided at the top of the structural columns of the high-rise building 1 in the anchorage zones 9 of the side span cable stays 8 and the top of the structural columns.

[0049] The steel frame 13 includes steel columns 13-2 on both sides, an upper steel beam 13-3 and a lower steel beam 13-1 fixedly connected to the steel columns 13-2 on both sides. The lower steel beam 13-1 of the steel frame 13 is embedded at the top of the building structural column 15. The steel columns 13-2 on both sides of the steel frame 13 extend downward into the building structural column 15, and several shear studs 16 are set on the outer side of the steel columns 13-2.

[0050] The side span double-sided steel box girder 5 is located in the center of the steel frame 13 and is encased by the steel frame 13. Compression supports 14 are respectively provided between the side span double-sided steel box girder 5 and the upper steel beam 13-3 and lower steel beam 13-1 of the steel frame 13, namely, upper compression support 14-2 and lower compression support 14-1. During the installation phase, under the self-weight of the side span double-sided steel box girder 5, the lower compression support 14-1 bears the force, acting as a positive reaction support; during the operation phase, the upper compression support 14-2 of the side span double-sided steel box girder 5 bears the force, acting as a negative reaction support.

[0051] The steel column 13-2 extending into the building structural column 15 and the shear studs 16 on the outer side of the steel column 13-2 can provide sufficient bonding force between the steel column 13-2 and the concrete of the building structural column 15, thereby transferring the uplift force of the compression support 14 as a negative reaction support to the building structural column 15.

[0052] To facilitate the replacement of the compression bearing 14, corbels 17 are installed on both sides of the web of the side span double steel box girder 5, with the top surface of the corbels 17 flush with the top surface of the side span double steel box girder 5; then, jacks 18 are installed on the top surfaces of the two steel corbels 17 respectively, and the compression bearing 14 can be replaced by simultaneously lifting the jacks 18.

[0053] In this invention, the mid-span ratio of the two sides of the cable-stayed bridge is less than 0.15, and the number of side span stay cables 8 does not exceed two sets. In this embodiment, the mid-span ratio of the two sides of the cable-stayed bridge is 0.12, and the number of side span stay cables 8 is two sets. The design of the mid-span ratio of the two sides of the cable-stayed bridge ensures that the weight of the side span main beam 4 is much smaller than that of the main beam of the middle span. Negative reaction forces only appear at the side span supports under the load of the middle span, thus allowing the structural columns 15 to effectively offset the load they bear. If the length of the side span were comparable to that of the middle span, the side span would act as a positive reaction support, which would increase the load on the structural columns and consequently increase the cost.

[0054] The two tower legs of the high-rise building 1 and the cable-stayed bridge 2 are fixedly connected by cantilever beams 10-1, with two cantilever beams 10-1 installed every 4-5 floors between the high-rise building 1 and the tower legs. The two tower legs of the cable-stayed bridge 2 are fixedly connected by tower crossbeams 10-2. The cantilever beams 10-1 reduce the free length of the tower legs 11, thereby reducing the cross-sectional area of ​​the tower legs 11. Compared with conventional tower legs, the cross-sectional area and bending section modulus of the tower legs 11 of the cable-stayed bridge 2 of this invention can be reduced by 1 / 4 to 1 / 3, greatly reducing the amount of steel used in the steel tower.

[0055] The lower tower column 11-1 of the cable-stayed bridge 2's tower limb 11 is made of concrete, while the upper tower column 11-2 is made of steel. The cantilever beam 10-1 connected to the concrete lower tower column 11-1 is a concrete beam, and the connection method is that the concrete beam and the concrete lower tower column 11-1 are cast in place simultaneously. The cantilever beam 10-1 connected to the steel upper tower column 11-2 is a steel beam, and the connection method is that the steel beam and the steel upper tower column 11-2 are welded together. The concrete lower tower column 11-1 extends into the raft foundation 12 of the high-rise building 1. The raft foundation 12 of the building within three times the length of the tower limb around the tower limb 11 is 60-90cm thicker than other areas. Since the cable-stayed bridge tower pier and the main body of the high-rise building 1 share the building raft foundation 15 and use the side span cable stays 8 in this invention, the cable-stayed bridge 2 does not have a pile foundation.

[0056] The construction method of the cable-stayed high-altitude sightseeing corridor of the present invention includes the following steps:

[0057] Step 1: Construct the raft foundation 12 of the high-rise building 1, and thicken the raft foundation 12 in the vicinity of the tower limb 11 of the cable-stayed bridge 2 (within a radius of 3 times the tower limb 11).

[0058] Step 2: Construct the main structure of the high-rise building 1 on both sides and the cable-stayed bridge tower 11. The construction of the cable-stayed bridge tower 11 will lag behind the high-rise building 1 by two stories. The cable-stayed bridge 1 tower will be installed using a shared construction crane. When the tower height of the tower 11 exceeds the design position of the cantilever beam 10-1, install the cantilever beam 10-1. Then install the tower crossbeam 10-2.

[0059] Step 3: After the high-rise building 1 is constructed to a certain height (design height of the bottom of the steel column 13-2), the steel column 13-2 of the steel frame 13 is pre-embedded in the building structural column 15, and the construction continues until the top is completed; after the building is topped out, the construction of the cable-stayed bridge 2 tower continues until the cable-stayed bridge 2 tower is installed.

[0060] Step 4: Use a tower crane for construction engineering to install the side span double-sided steel box girder 5 in sections, and reserve space 3 for elevator passage;

[0061] Step 5: Install the lower compression bearing 14-1 of the double-sided steel box girder 5 of the side span of the cable-stayed bridge 2, the upper compression bearing 14-2 of the double-sided steel box girder 5 of the side span, and weld the upper and lower steel beams of the steel frame onto the steel column 13-2; install the side span cable stays 8;

[0062] Step 6: Use a bridge deck crane to lift the 7 segments of the mid-span steel box girder section by section, and install the 8 stay cables one by one until the 7 segments of the mid-span steel box girder are closed; adjust the cable tension of the cable-stayed bridge.

[0063] Step 7: Install elevators on both sides of the high-rise building 1; install bridge deck auxiliary structures; complete the construction of the cable-stayed bridge-style high-altitude sightseeing corridor.

[0064] The foregoing detailed examples of the present invention are merely preferred embodiments and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the present invention should still fall within the patent coverage of the present invention.
