Embodiment 1

[0055] Please see attached figure 1 , the architectural shape is a warship, implying to go forward bravely. The building height is 22m. In order to ensure the large inclination angle of the front and rear of the warship, the cantilever of the second floor relative to the first floor is 8.9m, and the cantilever of the third and fourth floors is 15.6m relative to the first floor.

[0056] Please see attached figure 2 , all loaded steel columns 1 fall on the embedded part of the negative floor 100, and the embedded joints are anchored by 6M32 and 4M30 high-strength anchor bolts 61, embedded slabs 62 and the structure of the negative floor 100 to support the upper eccentric load. The floating grout at the horizontal construction joints must be chiseled out, and high-strength grouting materials are used to fill the joints under the pre-embedded slab 62 so that no gaps are left and the structural integrity is ensured.

Abstract

The invention discloses a large-span step-by-step cantilevered diagonal bracing structure based on an upper pull-down and lower embedded structure and a construction method thereof. , tie beams (4) and prestressed tendons (5); the bottom of the load steel frame column is fixed in the negative layer (100), and the top of the load steel frame column is fixed on the roof layer (200); On the load steel frame column (1) of the first floor (300), the eccentric angle of the diagonal brace and the load steel frame column is formed between the diagonal brace and the load steel frame column; the steel frame beams are connected by tie beams and set on the load steel frame columns to form the structure of the building. For several levels, the diagonal braces extend upwards to the top floor and are fixed with the steel beams of each level through tie beams to form a step-by-step cantilever structure; the prestressed tendons are anchored on the fixed structural columns (201), and the prestressed tendons are set Steel beams and anchored. The invention can meet the architectural requirements of the oblique shape of the large-span cantilevered step by step in the building structure through the construction technology of pulling up and inserting diagonal braces.

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...
