Newly increased cantilever beam frame steel armored anchor-pulling-method structure and process

Abstract

The invention relates to a newly increased cantilever beam frame steel armored anchor-pulling-method structure. The newly increased cantilever beam frame steel armored anchor-pulling-method structure comprise frame beams, frame columns and cantilever beams, wherein the frame beams and the frame columns are of concrete structures, the frame beams are provided with beam outside armored steel, the frame columns are provided with column outside armored steel, the beam outside armored steel is fixedly connected with the column outside armored steel, steel anchoring plates are fixedly connected to the outer side of the column outside armored steel, rib embedding holes are formed in the steel anchoring plates, the steel anchoring plates and the frame columns are fixed by adopting high-strength bolt embedded bars in an opposite-pull mode, the cantilever beams are fixedly connected with the steel anchoring plates, and the bottoms of the cantilever beams are fixedly connected with the column outside armored steel through diagonal supports. In addition, steel stay ropes can be arranged for further reinforcement. Outside armored steel trusses, horizontal embedded bars, the steel anchoring plates, the cantilever beams, the diagonal supports and the steel stay ropes form a statically indeterminate structure system, the members of the system are mutually connected and are jointly stressed to form multiple bearing protection lines, and multiple contradiction of a newly increased cantilever beam structure are solved.

Description

technical field [0001] The invention relates to a steel-clad anchor pull method structure and technology for a new cantilever frame, which is suitable for addition and renovation projects of existing buildings. Background technique [0002] Since my country's reform and opening up in the 1970s, the number of various housing buildings and urban facilities has increased sharply. Among them, a large number of industrial and civil buildings built in the early days of the founding of the People's Republic of China have been in service for a long time, and the old structural design cannot meet the needs of current use in terms of function. The building renovation and expansion industry is developing rapidly. In particular, the maintenance, reinforcement, renovation and upgrading of old cities has almost become a common topic for major and medium-sized cities. [0003] The engineering transformation of existing buildings due to the change of the building plane’s use function, such ...
