Abstract
The invention relates to the field of constructional engineering, particularly to the reinforcing of a building structure, and discloses a method for integrally reinforcing a masonry structure by sectional steel combined ring beams and construction columns. The technical scheme is as follows: angle irons, steel plates and through screws are adopted to form a combined section with an original wall body at the positions, where construction columns need to be arranged, of the masonry structure; the sectional steel ring beam is arranged at the joint of the wall body and a floor and is connected in a welding manner with the sectional steel and the steel plates in a combined column, and then polymer mortar is filled and compacted between the wall body and the sectional steel (steel plates). After the method is adopted to reinforce the masonry structure, the horizontal ultimate bearing capacity of the reinforced masonry structure is increased by more than 25% compared with that of a masonry structure employing the existing anti-seismic norms and requirements, and the loaded property and the anti-seismic property are greatly improved; meanwhile, compared with the additional reinforced concrete ring beams and the construction columns, the method has the advantages that the period of construction is short, the construction process is simple, no template needs to be set up, the use space is not applied, etc., and the method is suitable for improving the overall anti-seismic property of the large quantity of extensive masonry structures without the ring beams and the construction columns.
