Construction technology of formwork support system of high-altitude cable-stayed steel operating platform

Abstract

The invention discloses a construction technology for a high-altitude oblique-pulling structural-steel-operating-platform-formwork supporting system. The construction technology includes the following steps of 1, construction preparing, wherein it is determined that the scheme of a formwork supporting structure is whole-audience supporting frames, a structural-steel operating platform is the oblique-pulling structural-steel operating platform; 2, high-altitude oblique-pulling structural-steel-operating-platform-formwork-supporting-system bearing capacity checking and calculating; 3, oblique-pulling structural-steel-operating-platform constructing, wherein structural-steel beams are constructed and subjected to oblique pulling; 4, formwork supporting structure constructing. The construction technology is simple in step and reasonable in design, the structural-steel operating platform is used as the oblique-pulling structural-steel operating platform, the formwork supporting structure is supported on the structural-steel beams, and safety risks are reduced; the elastic deformation amount and the non-elastic deformation amount of the formwork supporting structure can be determined through an experiment before construction, and when formworks of nth roofs are erected, flexibility deformation can be controlled by the reserved deformation amount, the construction period can be shortened, and meanwhile the favorable construction operation platform can be provided for later decoration engineering.

Description

technical field [0001] The invention belongs to the technical field of building structure construction, and in particular relates to a construction process for a formwork support system of a high-altitude cable-stayed section steel operating platform. Background technique [0002] With the development of urban construction, architects have given full play to their ingenuity and wisdom, and many beautiful and generous buildings have emerged one after another, which has brought visual impact to people, but also brought great challenges to engineers. In particular, public buildings often use high-altitude and large overhangs to meet the needs of styling, such as setting large overhanging steel structure decorations along the roof of the building to achieve a spacious, transparent, and wide-view architectural effect. [0003] Escalator facilities in public buildings are usually hollow ring structures with many floors and a large space height. When the top floor structure is a co...

Problems solved by technology

[0005] The technical problem to be solved by the present invention is to address the deficiencies in the above-mentioned prior art, a construction process for the formwork support system of the high-altitude cable-stayed section steel operation platform, the method has simple steps, reasonable design, convenient implementation, and good use effect, and the section steel operation platform As a cable-stayed section steel operation platform, the formwork support structure is supported on the section steel beam, and there is no section steel support frame at the lower part of the cable-stayed section steel operation platform, which reduces the safety risk. The size of the elastic deformation can control the deflection deformation by reserving the deformation amount when supporting the formwork used to form the concrete pouring of the n-th floor roof, which is beneficial to shorten the construction period and provide favorable construction for the later decoration and decoration projects operating platform
