Flat steel pull rod for reinforcement and construction method thereof

Abstract

The invention, which belongs to the field of comprehensive reinforcement of anti-seismic strengthening, relates to a masonry structure with a flat steel pull rod for reinforcement and a construction method thereof. The masonry structure comprises a flat steel pull rod and pull rod support bases. The flat steel pull rod is arranged in a wall dust hole formed at a horizontal position in contact withthe wall at the lower side of a floor or a roof panel; the pull rod support bases are arranged at the two ends of the flat steel pull rod; and the pull rod support bases are arranged opening slots, close to an inner longitudinal wall or an outer longitudinal wall, of the two ends of a horizontal wall respectively. The pull rod support bases are welded with the flat steel pull rod by end plates, upper stiffening ribs, left stiffening ribs, and right stiffening ribs. The pull rod support bases at the two sides of the wall are pulled to right places by connection bolts and the symmetric tensioning of the pull rod support bases is realized by the connection bolts penetrating connecting holes of the end plates, rubber gasket holes, and drilled holes in the wall. Therefore, the coordinated workof the flat steel pull rod and the wall body is ensured; the stress lag phenomenon is reduced; and the good anti-seismic strengthening effect is realized.

[0002] With the development of society, people have higher and higher requirements for the quality of life and the safety of the living environment. In the face of the ubiquitous masonry structure houses, more reinforcement measures have been studied and applied to such buildings. In the seismic reinforcement of masonry structures, the traditional reinforcement methods are mostly wet work of cast-in-place concrete, which requires supporting formwork and demolition, and the construction period is long. Sometimes the thickness of the wall needs to be increased to reduce the usable area of ​​the building, and it needs to be demolished before construction. , to make up for the shortcomings after construction, which increases the amount of work and construction costs

At the same time, due to the great influence of the environment and the site, the selection and use of traditional reinforcement methods are limited. Therefore, a new and reasonable reinforcement method is studied-using flat steel tie rods to strengthen the masonry structure, so as to reduce the construction surface as much as possible. Solve some problems caused by traditional reinforcement methods
