Application and construction method of high-altitude, large-span and heavy-load tool-type formwork supporting steel platform

Abstract

The invention provides a use and construction method of a high-altitude, large-span and heavy-load tool-type formwork supporting steel platform. The high-altitude, large-span and heavy-load tool-typeformwork supporting steel platform can be used for a top-layer construction platform of a high-altitude and large-span building structure, an aerial connected structure and a high-altitude and large-span structure. The construction method includes the following steps that a tool-type steel structure platform and a formwork supporting frame are integrally assembled on the ground; a main body vertical structure is constructed first to reach a scheduled elevation; design and construction of temporary bearing points of the main body structure are carried out; installation of intelligent lifting machinery and connection fixing at the temporary bearing points of the main body structure are carried out; and a preloading load test and test verification on the ground are carried out. According to the construction method, the intelligent control of autonomous overall synchronous lifting of the high-altitude, large-span and heavy-load tool-type formwork supporting steel platform is realized, thetop-layer construction and monitoring of a high-altitude, large-span and heavy-load concrete main body structure are realized, and the principles are scientific, the method is ingenious, the technology is advanced, the safety and the reliability are realized, the technology is simple, the construction period is shortened, the cost is reduced, the labor intensity is reduced, and by combining an intelligent monitoring system, the active safety in the construction process of a main body horizontal structure is realized.

Description

technical field [0001] The invention relates to the technical field of civil engineering construction, in particular to the use and construction method of a high-altitude, large-span, heavy-load tool-type formwork supporting steel platform. 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 high-altitude, 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, urban ultra-high conductivity buildings are increasing. Due to the scarcity of land resources, high-altitude long-span building structures, aerial conjoined structures, high-altitude large-span, and large cantilever structures are increasin...

AI Technical Summary

Problems solved by technology

[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
