Description

Technical Field

[0001] The utility model relates to the technical field of building construction, and particularly to a sliding construction device for an inner courtyard steel structure connecting corridor. Background Technique

[0002] A steel structure connecting corridor is a bridge or passage composed of a steel structure, connecting two or more buildings, or spanning obstacles such as streets and roads, providing a convenient way for pedestrians or vehicles to pass. The steel structure connecting corridor has the characteristics of light weight, high strength, strong durability, etc., and can adapt to various complex terrains and environmental conditions at the same time. According to different application scenarios and design features, the steel structure connecting corridor can be divided into the following categories: Pedestrian overpass: Used for pedestrian passage, generally set in public places such as parks, shopping centers, etc., which is the most common type of steel structure connecting corridor. Vehicle overpass: Used for vehicle passage, mostly seen in places such as highways and urban transportation hubs, which can effectively relieve traffic pressure. Industrial plant connecting corridor: Used to connect industrial plants or warehouses, facilitating the transportation of goods and the passage of personnel. Connecting corridors in cultural buildings such as exhibition halls and museums: In order to provide a better visiting experience, some large exhibition halls or museums will set up steel structure connecting corridors to facilitate tourists to move quickly between different exhibition areas. Commercial building connecting corridor: Used to connect commercial buildings to form a large commercial complex and improve commercial efficiency.

[0003] Most of the current steel structure connecting corridors on the market are disassembled into scattered parts, and then a crane is used to lift the parts to the installation position, and then assembly and welding are carried out. Although disassembling and then assembling can facilitate the rapid lifting of each part, not only is the welding workload huge during high-altitude assembly, but there are also relatively large quality problems and safety hazards, and the construction difficulty is relatively large. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0026] In order to more clearly explain the overall concept of the present utility model, the following will be further described in detail by way of examples in combination with the accompanying drawings of the specification.

[0027] Embodiment 1:

[0028] Please refer to Figures 1 to 5 , the present utility model provides a technical solution: an inner courtyard steel structure corridor sliding construction device, including:

[0029] Floor 1, a bottom tire rack 2 is provided at the bottom of the floor 1, and a civil engineering beam column 3 is provided at the top of the bottom tire rack 2;

[0030] Lifting support 4, a sliding beam 5 is arranged at the top of the lifting support 4, a hydraulic lifter 8 is arranged on the top surface of the sliding beam 5, and a hydraulic crawler 11 is arranged on the side of the hydraulic lifter 8.

[0031] Through the bottom support frame 2 and the civil building beams and columns 3, construction workers can assemble and weld the corridor body 16 on the bottom support frame 2. After welding, the hydraulic lifter 8 drives the steel strand 9, and the steel strand 9 drives the lifting beam 10 to lift the corridor body 16 as a whole to the installation position, greatly reducing the installation construction difficulty, and at the same time ensuring the construction quality and construction progress.

[0032] Embodiment Two:

[0033] As Figures 2 - 3 shown, the internal courtyard steel structure corridor sliding construction device disclosed in the second embodiment of the present utility model has basically the same structure as that in the first embodiment, and the differences are as follows:

[0034] The bottom support frame 2 is arranged corresponding to the structural axis, and a plurality of the civil building beams and columns 3 are fixedly installed on the top of the bottom support frame 2, and the plurality of civil building beams and columns 3 are distributed in a linear array on the top of the bottom support frame 2.

[0035] The surface of the bottom support frame 2 is provided with a corridor body 16, and a plurality of support columns 17 are arranged on both sides of the corridor body 16.

[0036] A plurality of steel legs 18 are arranged inside the floor 1, and the number and size of the plurality of steel legs 18 are consistent with those of the support columns 17.

[0037] The lifting support 4 is arranged on the top of the floor 1, a threaded hole is arranged at one end of the bottom of the lifting support 4, a high-strength bolt 41 is arranged in the threaded hole, and the lifting support 4 and the floor 1 are connected by matching the threaded hole and the high-strength bolt 41.

[0038] A chute 6 is arranged on the top of the sliding beam 5, a slider 7 is slidably connected inside the chute 6, the number of the sliders 7 is multiple, and the multiple sliders 7 are distributed in a linear array inside the chute 6.

[0039] The hydraulic lifter 8 is arranged on the top of the slider 7, the steel strand 9 is arranged at the bottom of the hydraulic lifter 8, the steel strand 9 penetrates through the sliding beam 5 and extends to the bottom, and the lifting beam 10 is arranged at the bottom of the steel strand 9.

[0040] The lifting beam 10 is arranged at the middle chord position of the corridor body 16, and the width of the lifting beam 10 is greater than the width of the corridor body 16.

[0041] Through the hydraulic lifter 8 and the hydraulic crawler 11, multiple hydraulic lifters 8 can stably and safely lift the corridor body 16. When the hydraulic crawler 11 reaches the steel support leg 18, it performs a misalignment movement on the corridor body 16 to prevent the steel support leg 18 from colliding with the support column 17, which may affect the lifting of the corridor body 16.

[0042] Embodiment 3:

[0043] As Figures 4 - 5 shown, the in - court steel - structure corridor sliding construction device disclosed in Embodiment 3 of the present utility model has basically the same structure as that in Embodiment 2, and the differences are as follows:

[0044] The hydraulic crawler 11 is arranged on the side of the hydraulic lifter 8, and a fixed seat 12 is arranged at the bottom of the hydraulic crawler 11.

[0045] Preferably, a slide plate 13 is arranged at one end of the sliding beam 5 away from the hydraulic crawler 11. A baffle 14 is fixedly connected to the top of the slide plate 13, and a threaded rod 15 is arranged on the side of the slide plate 13.

[0046] Through the slide plate 13, the baffle 14 and the threaded rod 15, when using the hydraulic crawler 11 for misalignment movement, the distance between the baffle 14 and the hydraulic lifter 8 can be adjusted according to the width of the steel support leg 18, preventing the corridor body 16 from moving too much in the air and being affected by the wind speed, thus affecting its stability.

[0047] The specific scheme is as follows: First, construction workers can assemble and weld the corridor body 16 on the bottom falsework 2. Place the lifting beam 10 at the mid - chord positions at both ends of the corridor body 16, then connect the lifting beam 10 with the steel strand 9. Subsequently, measure the size of the steel support leg 18, then turn the threaded rod 15 to move the slide plate 13 on the sliding beam 5 so that the distance between the baffle 14 and the hydraulic lifter 8 is the same as the size of the steel support leg 18. Subsequently, start the hydraulic lifter 8. The hydraulic lifter 8 drives the steel strand 9, and the steel strand 9 drives the lifting beam 10 to lift the corridor body 16 as a whole to a position 10 centimeters below the bottom of the steel support leg 18. Then start the hydraulic crawler 11 to drive the hydraulic lifter 8 to move to the baffle 14 and stop. Then the hydraulic lifter 8 works to lift the corridor body 16 to a position 10 centimeters above the top of the steel support leg 18. Subsequently, the hydraulic crawler 11 retracts to drive the hydraulic lifter 8 back to its original position. Finally, lower the corridor body 16 to complete the installation, which greatly reduces the installation construction difficulty and also ensures the construction quality and construction progress.
