Method for increasing ring beam for brick masonry wall

Abstract

The invention discloses a method for increasing a ring beam for a brick masonry wall for solving the problems that the reinforcement effect is bad, the construction process is complex and the appearance of a building is influenced after the ring beam is increased in the conventional method for increasing the ring beam for the brick masonry wall. The method comprises the following steps of: horizontally arranging longitudinal reinforcements at four corners on which the constructional column is pre-increased under the floor of the brick masonry structure; longitudinally holing along horizontal mortar joints every 150 to 300mm at intervals along with ring beam and allowing a stirrup to penetrate through the hole; and finally, daubing high-elongation fiber concrete on the surface of the wall on which the ring beam is pre-increased. The ring beam is increased by utilizing the mechanical property characteristics of the high-elongation fiber concrete and high adhesion performance between the high-elongation fiber concrete and the brick masonry, so that the integrity of the wall can be greatly improved, brittle failure is avoided, and the seismic resistance of the brick masonry wall is obviously improved. The method has the characteristics of good reinforcement effect, simple construction process and low influence on the appearance of the original building.

Description

technical field [0001] The invention belongs to the technical field of earthquake resistance and reinforcement of building structures, and in particular relates to a method for adding ring beams to brick masonry walls. Background technique [0002] Adding ring beams to brick masonry walls is an effective seismic strengthening method for masonry structures. Adding ring beams to brick masonry walls is to add ring beams to the wall under the concrete floor. The existing method is to add concrete ring beams. Beams and steel tie rods, the specific construction steps of this method are as follows: [0003] Step 1: According to the provisions of GB50011 of "Code for Seismic Design of Buildings", the size and position of the pre-installed ring beams are determined according to the number of floors of the building to be reinforced, the seismic fortification classification and the intensity; [0004] Step 2: Add steel tie rods along both sides of the transverse wall at the place wher...

AI Technical Summary

Problems solved by technology

[0007] The construction process of the above method is relatively complicated, and the formwork needs to be supported on the construction site. The increase in ductility after reinforcement is limited, and ring beams are added on the outside of the original building, which seriously affects the appearance of the original building.
