Method for reinforcing brick-concrete structure by utilizing angle steel frame

Abstract

The invention relates to a method for reinforcing a brick-concrete structure by utilizing an angle steel frame, belonging to the anti-earthquake reinforcement field. According to the method disclosed by the invention, a reliably connected steel frame formed by double-angle steel can replace a ring beam and a structural column, and field bolt assembly connection through factory pre-fabricated components can be realized, thus the safe, environment-friendly and green construction is realized; simultaneously, angle steel, a wall and a pre-fabricated floor slab are connected by bolts and epoxy resin, and the double-angle steel is also can be used as a round hole plate end part support, so that the connection reliability of the pre-fabricated floor slab and the wall is ensured, double functions of the ring beam and a supporting beam are exerted, reinforcement workload and cost are saved, and the original structure and reinforcement components mutually and cooperatively work. According to the method for reinforcing the brick-concrete structure by utilizing the angle steel frame, disclosed by the invention, the binding-type reinforcement construction speed is fast, and the reinforcement construction is safer, so that the method is very suitable for residential buildings.

Description

technical field [0001] The invention relates to a strengthening method, in particular to a method for strengthening a brick-concrete structure by adopting an angle steel frame, belonging to the field of seismic strengthening. Background technique [0002] Brick-concrete structure is a traditional structural form in our country, with a development history of thousands of years, which is the national condition of our country. There are generally three types of masonry structures: one is unreinforced masonry structure. It is a brittle material structure with low ductility and poor deformation resistance. It is prone to sudden collapse and damage during earthquakes, so it is not an earthquake-resistant building. The second is the reinforced structure. By disposing horizontal steel bars in the masonry, the ductility of the structure is increased and the deformation resistance is improved. It is generally used in multi-height and multi-storey masonry structures, such as reinforce...

The second is the reinforced structure. By disposing horizontal steel bars in the masonry, the ductility of the structure is increased and the deformation resistance is improved. It is generally used in multi-height and multi-storey masonry structures, such as reinforced concrete block buildings, but in In the existing masonry structure buildings in our country, less

However, the overall collapse resistance of the structure is significantly enhanced
