High-altitude construction method of multi-storey, long-span and heavy-duty concrete structures

Abstract

The invention provides a high-altitude construction method of a multi-layer long-span heavy-load concrete structure. The combination of an intelligent lifting tool type template supporting steel platform and an intelligent monitoring system, reserved construction from the top to the bottom is conducted on the horizontal structure in the multi-layer long-span heavy-load concrete structure, the mainconstruction method includes the following steps that the high-altitude long-span heavy-load tool type template supporting steel platform and a template supporting rack are integrally combined on theground, the vertical structure of a body is constructed to a preset elevation in advance, a temporary bearing point is arranged on the vertical structure of the body, intelligent lifting machinery ismounted on and fixedly connected with the temporary bearing point of the body structure, after preloading load verification is conducted on the ground, intelligent control automatic overall synchronous lifting is conducted, reserved construction from the top to the bottom is conducted on the horizontal structure of the body, and platform automatic synchronous falling is conducted. The high-altitude construction method of the multi-layer long-span heavy-load concrete structure has scientific principle, ingenuity methods, advanced technology and is safe, reliable and simple and convenient in technology, the construction period is shortened, the cost is lowered, and labor intensity is lightened. Combined with the intelligent monitoring system, active safety, in the construction process, of the horizontal structure of the body is realized.

Description

technical field [0001] The invention relates to the technical field of civil building construction, in particular to a high-altitude construction method of a multi-layer, large-span and heavy-load concrete structure. Background technique [0002] The height, span and load of modern buildings are getting bigger and bigger. The difficulty of construction technology organization and management and the danger of operation are also increasing. The difficulty of construction of multi-storey, long-span and heavy-load concrete structures is often beyond the scope of general and traditional construction methods. [0003] With the development of economy and society and the continuous improvement of construction technology, there are more and more high-rise and super high-rise buildings in cities. The number of designs is increasing; the difficulty and risk of construction have also increased significantly, and vicious accidents such as the overall collapse of the high-altitude formw...

Problems solved by technology

For large-span and heavy-duty structures with a dangerously large height exceeding a certain scale, after analysis and calculation, the bearing capacity and stability of support frames such as fasteners, bowl buckles, and disc buckles often cannot meet the above-mentioned special requirements. To meet the formwork support requirements of the structure, a new construction method must be found, and at the same time, it must meet the construction needs of simple structure, reusable utilization, simple process, economical, safe, reliable, fast and convenient

[0005] Due to the characteristics of the high-altitude long-span concrete main structure, such as high distance from the ground, large span, self-heaviness, and large construction load, the traditional full-floor ordinary high-support formwork method is used for construction, and a huge steel pipe scaffold needs to be erected. Compared with the ground work, the quality of high-altitude work is reduced. The large-scale support frame has many manual fastening nodes, many loose nodes, many hidden dangers, difficult inspection and detection, long construction period, high labor intensity, high engineering cost, and large construction site occupation. , Construction safety is difficult to guarantee and other disadvantages
