Abstract

The invention discloses a large-span step-by-step cantilever inclined strut structure based on a pull-up and lower-insertion structure and a construction method of the large-span step-by-step cantilever inclined strut structure. The large-span step-by-step cantilever inclined strut structure comprises load steel reinforced columns (1), an inclined strut (2), steel reinforced beams (3), tie beams (4) and prestressed tendons (5); the bottoms of the load steel reinforced columns are fixed into a negative layer (100), and the tops of the load steel reinforced columns are fixed to a roof layer (200); the inclined strut is fixed to the load steel reinforced column (1) of a first floor (300), and an inclined strut eccentric angle is formed between the inclined strut and the corresponding load steel reinforced column; the steel reinforced beams are connected through the tie beams and then are disposed on the load steel reinforced columns to form a plurality of floors of a building structure, the inclined strut extends upward in an inclined mode to the top layer and is fixed to the steel reinforced column of each level through the tie beams to form a step-by-step cantilever structure; and the prestressed tendons are anchored on a fixing structural column (201), and the prestressed tendons are arranged in the steel reinforced beams and anchored. According to the large-span step-by-step cantilever inclined strut structure based on the pull-up and lower-insertion structure and the construction method of the large-span step-by-step cantilever inclined strut structure, the architecturalrequirement of the large-span step-by-step inclined shape in the building structure can be met through the construction technology of pull-up and lower-insertion diagonal bracing.

Description

technical field [0001] The invention relates to a cantilevered structure in construction engineering and a construction method thereof, in particular to a large-span step-by-step cantilevered diagonal bracing structure based on an upper-pull and lower-embedded structure and a construction method thereof. Background technique [0002] In recent years, in various construction projects, various novel architectural shapes have adopted a large number of inclined structures. In order to meet the requirements of architectural design and the use of internal architectural space, the cantilever structure has become an important architectural structure in construction projects. Components, with the continuous development of construction engineering technology, various large-span cantilevered structural forms are becoming more and more complex. [0003] The Chinese invention patent application with the publication number CN109138165A discloses a super-large-span self-formed pre-tensione...
