Description

Technical Field

[0001] This invention relates to the field of aerial walkway technology, and in particular to a construction method for a large-scale aerial walkway structure with multiple curvatures. Background Technology

[0002] With social development and technological progress, and based on the development and improvement of modern physics and mechanics theories, the technical barriers in the construction field are becoming increasingly smaller. Architectural designers can design various unique and ingenious buildings according to project needs, which are then implemented by construction companies. As people's demands for architectural style increase, various irregularly shaped buildings are emerging one after another, and skywalks are one such example. In recent years, skywalks have sprung up rapidly, showing a rapid increase in numbers. However, given their elevated design, they inherently carry certain safety risks and require higher standards in terms of wind and earthquake resistance. In particular, large skywalks with curvatures need to consider the stability and safety of their overall structure during design and construction. How to provide beautiful sightseeing views while minimizing safety risks and facilitating construction is one of the problems that the current field of large-scale skywalk technology needs to solve.

[0025] The beneficial effects of this invention are reflected in:

[0026] 1) The present invention provides a construction method for a large-scale multi-curvature skywalk structure. Based on the detailed design of the BIM model, the W-shaped multi-curvature skywalk is divided into six unit truss structures. The six unit truss structures are then welded and assembled on the ground and then hoisted one by one and welded together in the air. This method is more convenient and saves time and effort during hoisting. It provides an installation approach for multi-curvature skywalks and solves the technical problem of difficult installation of multi-curvature skywalks.

[0027] 2) The present invention provides a construction method for a large-scale multi-curvature aerial walkway structure. Before hoisting the unit truss structure, vertical support structures are installed at corresponding points according to the design points of the BIM model to provide temporary support for the unit truss structure and a connection platform for the unit truss structure, ensuring smooth installation. After the unit truss structure is hoisted, diagonal support structures are installed at the positions of the vertical support structures to provide diagonal support force for the assembled aerial walkway. Finally, cables are installed to provide diagonal tie force for the aerial walkway, further increasing the overall stability.

[0028] 3) The construction method of a multi-curvature large-scale aerial walkway structure provided by the present invention is that most of the welding work is carried out on the ground, with less high-altitude welding work and a high safety factor; the aerial welding work is only carried out at the junction of the two C-shaped structures, which is located at the middle outer edge of the frame building. Workers can stand on the frame building to carry out welding, which is relatively safe.

The aerial walkway adopts a triangular spatial truss structure with a cross-sectional height of 1.2m. The main construction contents of the aerial walkway include: fan coil unit installation, air conditioning water pipe installation, greywater pipe installation, cable tray installation, pipe insulation, and electrical cable installation. Analysis of construction difficulties: The aerial walkway is a cantilever structure with a minimum height of 6 meters and a maximum height of 22 meters. It is a triangular spherical node steel structure, and all electromechanical pipelines and equipment are inside the triangle. If the installation work is carried out after the steel structure is hoisted, not only will the machinery rental cost increase, but high-altitude work will also be more dangerous, reducing worker efficiency and increasing construction costs. After consultation with the steel structure unit, a method of simultaneous construction with the steel structure was adopted. That is, when the steel structure is spliced ​​on the ground, the electromechanical installation is carried out in an interspersed manner, and finally the steel structure is hoisted as a whole. In the later stage, a boom lift is used to connect the fan coil units and pipelines between sections.

The construction method for a large-scale multi-curvature aerial walkway structure as described in claim 5, characterized in that, In step four, the base (34) is first fixed to the ground with bolts, and then the first layer of tower crane standard section is installed on the base (34) and welded to the embedded plate (35) on three sides. The tower crane standard section is then hoisted and fixed layer by layer.

8. The construction method of a large-scale multi-curvature aerial walkway structure as described in claim 1, characterized in that, In step five, the specific hoisting steps of the aerial walkway are as follows: hoist the C-shaped structure composed of the first unit truss structure (21), the second unit truss structure (22) and the third unit truss structure (23), install one end of the C-shaped structure on the outer right side of the frame building (1) and the other end on the outer middle of the frame building (1); then hoist the C-shaped structure composed of the fourth unit truss structure (24), the fifth unit truss structure (25) and the sixth unit truss structure (26), install one end of the C-shaped structure on the outer middle of the frame building (1) and the other end on the outer left side of the frame building (1).

9. The construction method of a large-scale multi-curvature aerial walkway structure as described in claim 1, characterized in that, In step seven, four cables are installed, which are respectively set on the upper end face of the first upper chord (51) at the four inclined support structures (4).

10. The construction method of a large-scale multi-curvature aerial walkway structure as described in claim 1, characterized in that, In step eight, after the aerial walkway is installed, at least ten measuring points are set up on the aerial walkway, and then a total station is used to measure the deformation and deflection of the aerial walkway.
