A construction method for reinforced beams with carbon fiber cloth and steel components

Abstract

The invention relates to a construction method of a carbon fiber cloth steel member combination strengthening beam, and belongs to the field of structural seismic reinforcement. According to the construction method, as for the portion, where does not satisfy standard requirements after seismic appraisal of an underground space structure, of the beam, the bottom of the beam is firstly reinforced through carbon fiber cloth, and supporting reinforcement is conducted through a newly added H type steel beam structure. Due to the fact that the anchoring measures of steel members and bolts are added to the joint of the beam and a column, the new and original structures can be combined better to achieve the supporting function together. Meanwhile, holes are preformed for the steel members according to actual conditions, a certain amount of prevenient preparation work is conducted on following pipeline engineering, and underground space is utilized effectively. The construction method can well resolve the connection problem between the newly added H type steel beam structure and the original structure.

Description

technical field [0001] The invention relates to an existing building reinforcement technology and construction method which comprehensively adopts carbon fiber and section steel components for reinforcement, and belongs to the field of seismic reinforcement. Background technique [0002] With the rapid development of social economy, the problem of land shortage in big cities is getting worse day by day. Especially in densely populated metropolises, the pressure on land supply in the central urban areas is very prominent. In order to alleviate this contradiction, it is a practical need to carry out the renovation of existing buildings such as old cities or old residential areas, and to utilize the underground space of existing buildings. [0003] However, the technical difficulty of adding floors to existing buildings lies in whether the original structural system can still meet the safety requirements after adding floors, and whether a reliable connection can be formed betw...
