Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of building engineering, and particularly relates to a cable-stayed gallery bridge arranged between buildings. BACKGROUND

[0002] The gallery bridge, also called a rainbow bridge or a centipede bridge, is a bridge with a roof, which can protect the bridge from wind and rain and provide a place for pedestrians to take shelter from the wind and rain and rest and view the scenery. With the continuous development of urban construction, connecting passages are often arranged between different buildings in some large commercial complexes, office building groups or residential areas to facilitate personnel traffic, improve space utilization and enhance the integrity of the building group.

[0003] The traditional connecting mode between buildings is a simple flat bridge structure, which relies on the support of the building on the bridge body and bears the load through the bending resistance of the main beam of the bridge body. However, this structure has many drawbacks when facing large span requirements. When the span increases, the bending moment and shear force borne by the main beam will increase sharply, resulting in a substantial increase in the cross-sectional size and material consumption of the main beam, which not only causes a great waste of resources and significantly increases the construction and maintenance costs of the gallery bridge, but also greatly reduces the stability of the gallery bridge due to the increase in the structure weight, and there is a great safety hazard when facing natural disasters such as strong winds, heavy rains and snow. CONTENT OF THE UTILITY MODEL

[0004] In view of the problems and deficiencies of the prior art, the utility model provides a cable-stayed gallery bridge arranged between buildings, which effectively solves the problems of the traditional flat bridge structure in large span through innovative structural design, realizes efficient and stable construction of the gallery bridge in large span, reduces the construction and maintenance costs, and improves the space utilization and safety.

[0005] The utility model is implemented through the following technical solutions:

[0006] A cable-stayed gallery bridge arranged between buildings is installed between a first building and a second building, and comprises a tower, a main beam and a stay cable. The tower is fixedly arranged between the first building and the second building, and a first hinged seat is fixedly arranged above the tower. The main beam is fixedly connected with the first building, the second building and the tower, and two side walls are fixedly arranged on the two sides of the main beam. An arc-shaped plate is fixedly arranged on the main beam. The main beam, the side walls and the arc-shaped plate jointly form a pedestrian passage. The main beam comprises a beam body and a support rod penetrating through the beam body, and two second hinged seats are arranged on the two sides of the support rod. The stay cable is connected between the first hinged seat and the second hinged seat, and a lock is arranged between the stay cable and the second hinged seat. The core structure of the cable-stayed gallery bridge converts the single bending structure of the traditional flat bridge into a multi-point tensile structure through the triangular force system of the tower-main beam-stay cable, significantly reduces the bending moment of the main beam and expands the applicable span range.

[0007] Further, the main girder comprises two main steel plates, a plurality of cross beams connecting the two main steel plates, and a plurality of vertical beams laid above the cross beams, and the supporting rods penetrate through the two main steel plates. The main steel plates, the cross beams and the vertical beams work together, and the supporting rods penetrate through to enhance the overall strength, improve the bearing capacity of the main girder to various loads, and ensure the safety and reliability of the gallery bridge structure.

[0008] Further, the side wall plate comprises a triangular truss and a glass plate installed outside the triangular truss. The triangular truss provides stable support, and the glass plate ensures light transmission and protection performance, improves the aesthetics and practicality of the gallery bridge, and enhances the ability of the gallery bridge to resist wind and other external forces.

[0009] Further, the width of the arc-shaped plate is greater than the distance between the two side wall plates, and the arc-shaped plate is made of transparent material. The overhanging and transparent design not only meets the architectural aesthetic requirements, but also creates a good passing environment for pedestrians, while enhancing the rain and wind resistance of the gallery bridge, and to some extent, avoiding snow accumulation.

[0010] Further, the locker comprises a first lock plate fixed to the bottom of the stay cable and a second lock plate fixed to the second hinge seat, at least two groups of through holes are formed in the first lock plate and the second lock plate, the locking rod penetrates through the lock holes of the first lock plate and the second lock plate, and the locking nut is screwed to the locking rod to adjust the distance between the first lock plate and the second lock plate. By adjusting the distance between the lock plates to adjust the tension of the stay cable, it is ensured that the stay cable is always in the best working state, and the stability of the gallery bridge structure is maintained.

[0011] Further, two locking nuts are arranged at one end of the locking rod, and the rotation directions of the two locking nuts are opposite. By using the reverse tightening force of the double locking nuts, the locking effect is enhanced, the loosening of the nuts caused by vibration and other external forces is prevented, the stability of the stay cable tension is ensured, and the safety of the gallery bridge structure is ensured.

[0012] Further, the pile foundation is provided at the bottom of the tower, and the cross section of the pile foundation is larger than that of the tower. The tower bottom is provided with a large cross section pile foundation, which expands the foundation bearing area and improves the stability of the tower, so that the gallery bridge can better cope with various complex geological conditions and external forces.

[0013] Further, the lighting lamps and the guardrails are installed uniformly along the length direction of the main girder inside the pedestrian passage. The lighting lamps and the guardrails are installed in the pedestrian passage, the lighting lamps provide sufficient light, the pedestrian passage is convenient, the guardrails ensure the safety of the pedestrians, and the use experience of the gallery bridge is improved.

[0014] Further, the metal parts of the main girder and the side wall plate are sprayed with anti-rust primer, intermediate paint and topcoat. The primer is epoxy zinc-rich paint, the intermediate paint is epoxy cloud iron paint, and the topcoat is acrylic polyurethane topcoat. The metal parts are subjected to corrosion protection treatment, the service life of the metal parts is prolonged, the maintenance cost of the gallery bridge is reduced, and the long-term stability of the gallery bridge structure is ensured.

[0015] Further, displacement sensors are installed at the connection between the main beam and the building body and the connection between the main beam and the cable tower. The displacement sensors are installed to monitor the displacement of the connection between the main beam and the building body and the connection between the main beam and the cable tower in real time, to find potential safety hazards in time, to provide data support for maintenance of the gallery bridge, and to ensure safe operation of the gallery bridge.

[0016] The gallery bridge has the following beneficial effects:

[0017] 1. Improved structural stability: The cable-stayed structure shares the load of the main beam through the cable tower and the cable-stayed cable. Compared with the traditional flat bridge structure, the bending moment and shear force borne by the main beam are greatly reduced in the case of large span, the stability of the gallery bridge is significantly improved, and the risk of damage in natural disasters is effectively reduced.

[0018] 2. Reduced cost: Due to the reduction in the size of the main beam cross section and the reduction in material usage, the construction and maintenance costs of the gallery bridge are reduced, resource waste is reduced, and the concept of sustainable development is met.

[0019] 3. Improved functionality: The lighting fixtures and guardrails in the pedestrian walkway provide a safe and comfortable environment for pedestrians; the design of the side panels and arc-shaped panels enhances the rainproof, windproof, and lighting functions of the gallery bridge; the corrosion protection treatment of the metal parts prolongs the service life of the gallery bridge; and the installation of displacement sensors enables real-time monitoring of the structural safety of the gallery bridge, thereby improving the functionality and safety of the gallery bridge in all directions.

[0032] In one embodiment, in the construction of a corridor bridge between buildings in a commercial complex, a large commercial complex consists of two main buildings with a distance of 50 meters between them. A corridor bridge needs to be built between the two buildings to facilitate customer passage and improve the continuity of the commercial space.

[0033] Design and construction:

[0034] Tower 3: A reinforced concrete tower 3, 15 meters high, with a base cross-section of 4 meters × 4 meters. Tower 3 is equipped with multiple layers of transverse diaphragms and reinforcing ribs to enhance structural stability. A pin-hinged first hinged joint 31 is installed at the top.

[0035] Main Beam 4: The main beam 4 is a prestressed concrete beam, 1.5 meters high and 2.5 meters wide. The two main steel plates 46 are 30 mm thick. The crossbeams 47 are H-beams spaced 1.5 meters apart, and the vertical beams 48 are I-beams spaced 0.8 meters apart. The support rod 44 has a diameter of 15 cm and passes through the main steel plate 46.

[0036] Stay cable 5: High-strength steel strand stay cable 5 with a diameter of 50 mm. Locking device 6 adopts bolt locking method, the first locking plate 61 and the second locking plate 62 are 15 mm thick, the through hole diameter is 20 mm, and the locking rod 63 has a diameter of 18 mm.

[0037] Side panel 41: The triangular truss 411 is made of angle steel, and the dimensions of the members are determined according to mechanical calculations. A 6 mm thick high-strength tempered glass panel 412 is installed on the outside and fixed with stainless steel clamps.

[0038] Curved panel 42: Polycarbonate curved panel 42 is used, with a width 0.3 meters wider than the spacing of the side panels 41, and the curvature is determined according to the architectural design requirements.

[0039] Other facilities: LED lighting fixtures are installed in pedestrian walkway 43, one every 5 meters, with an illuminance of 60 lux. Stainless steel railings with a height of 1.1 meters are installed. The metal components of the main beam 4 and side panels 41 are coated with epoxy zinc-rich primer, epoxy micaceous iron oxide intermediate paint, and acrylic polyurethane topcoat according to anti-corrosion process requirements. Laser displacement sensors are installed at the connection points between the main beam 4 and the building body and cable tower 3.

[0040] After its completion, the covered bridge underwent load testing and long-term monitoring, demonstrating structural stability and meeting design requirements. It provides convenient pedestrian access, significantly improves the space utilization of the commercial complex, and its aesthetic design adds a distinctive touch to the commercial environment.

[0041] In one embodiment, the width of the curved panel 42 is greater than the distance between the two side panels 41, forming a cantilever structure that enhances the aesthetics and uniqueness of the covered bridge. The curved panel 42 is made of a transparent material, such as polycarbonate or acrylic, allowing for good light transmission and creating a bright and comfortable environment, while also providing rain and wind protection. Its curvature is precisely calculated to balance architectural aesthetics and structural mechanical performance.

[0042] In one embodiment, the locking device 6 consists of a first locking plate 61 fixed to the bottom of the stay cable 5 and a second locking plate 62 fixed to the second hinge seat 45. Both locking plates have at least two sets of through holes through which the locking rod 63 passes. The distance between the two locking plates is adjusted by tightening the locking nut 64, thereby adjusting the tension of the stay cable 5. The locking plates are made of high-strength steel plates, typically 10-20 mm thick. The diameter of the through holes is determined based on the size of the locking rod 63, generally 1-2 mm larger than the diameter of the locking rod 63. The locking rod 63 is made of high-strength alloy steel, and its diameter is determined based on the tension of the stay cable 5 and the stress analysis of the locking device 6, typically 15-30 mm.

[0043] In one embodiment, two locking nuts 64 with opposite directions of rotation are used at one end of the locking rod 63, utilizing the interaction force between the nuts to enhance the locking effect. When the bridge is subjected to vibration or other external forces, the reverse tightening force prevents the nuts from loosening, ensuring the stability of the tension of the stay cables. The two nuts are made of the same material as the locking rod 63 and have rust-proof surfaces. During installation, the tightening torque is controlled by a torque wrench to ensure uniform tightening force.

[0044] In one embodiment, a pile foundation 32 is provided at the bottom of the tower 3. The cross-section of the pile foundation 32 is larger than that of the tower 3, thereby increasing the foundation bearing area and improving the stability of the tower 3. The pile foundation 32 can be a reinforced concrete cast-in-place pile or a precast pile. Cast-in-place piles are suitable for different geological conditions, while precast piles ensure quality and speed up construction. The depth of the pile foundation 32 is determined based on the geological survey report, generally between 10 and 30 meters. The cross-sectional shape can be circular, square, or polygonal depending on the actual situation.

[0045] In one embodiment, lighting fixtures and guardrails are evenly installed along the length of the main beam 4 inside the pedestrian walkway 43. The lighting fixtures use energy-saving LED lights to ensure walkway brightness, with an illuminance of no less than 50 lux per square meter. Power is supplied via pre-embedded conduits, and can be either mains power or solar power. The guardrails are set at a reasonable height, generally 1.0-1.2 meters, and are made of stainless steel or aluminum alloy to ensure pedestrian safety.

[0046] In one embodiment, displacement sensors are installed at the connection points between the main beam 4 and the building structure, as well as at the connection points between the main beam 4 and the pylon 3. The displacement sensors can be laser displacement sensors or linear variable differential transformer (LVDT) displacement sensors, which monitor displacement changes at the connection points in real time. If the data exceeds a preset safety threshold, an early warning is issued promptly so that maintenance measures can be taken to ensure the safety of the covered bridge structure.

[0047] The above description is merely an embodiment of this application and is not intended to limit the scope of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of the claims of this application.
