Description

Technical Field

[0001] The present invention relates to the technical field of building construction, and more specifically, to curtain wall engineering construction equipment of a track-type hanger and a construction method thereof. Background Art

[0002] In current construction projects, stricter requirements are imposed on the progress control, safety control, standardization management, quality management and other aspects of on-site construction. For large-scale perimeter construction of buildings, such as curtain walls, exterior wall coatings and other projects, traditional scaffolding construction can no longer meet these requirements.

[0003] Its main disadvantages are:

[0004] 1. Frequent cross-operation and low utilization rate. If scaffolding is used for construction, once municipal and underground pipeline workers enter the site, the scaffolding will face the risk of being forced to be dismantled, making it difficult to use the scaffolding for subsequent construction work.

[0005] 2. It is not conducive to hoisting operations. For projects with long cantilevered eaves, it is difficult to use a crane to hoist the materials into place at once after setting up the scaffolding, and the hoisting operation efficiency is low.

[0006] 3. It is not conducive to the development of prefabricated construction. Prefabricated construction usually adopts the method of ground assembly and overall hoisting. The erection of scaffolding greatly affects the hoisting operation, making prefabricated construction difficult to achieve.

[0007] 4. Increased costs. For projects with long construction spans and wide construction areas, the cost of setting up scaffolding for construction is extremely high.

[0008] 5. For projects with long construction spans, it is difficult to form an effective connection between the frame and the main structure when setting up scaffolding. In addition, the area is open and the wind is extremely strong. Once the scaffolding is used, the windward area of ​​the measure will be greatly increased, and the safety of the frame will be low.

[0009] 6. There are various architectural forms, and the roof shape and structure often have ups and downs. It is difficult for scaffolding to fully adapt to such height changes. The arrangement of measures is complex and the erection is difficult.
