Method for consolidating tilting combination structure

Abstract

The invention discloses a method for consolidating tilting combination structure, mainly comprising the steps of laying a bonding course steel band on the surface of a concrete building to be consolidated, and welding a third steel board at the two ends of the bonding course steel band to be extended to the edge of a circumferentially connected profile steel concrete member, then arranging fixing points with the same structure respectively at the edge of the two ends, concretely, bolting a first steel board and a second steel board to the profile steel concrete member, wherein, the second steel board faces the third steel board, sequentially welding a first reinforced steel board, a second reinforced steel board, a T-shaped profile steel board and a triangular steel board between the second steel board and the third steel board in a way of reasonable combination. In the consolidation method, only a welding-bolting technology is used for fixing a plurality of steel boards in certain shapes to the building to be consolidated and the connected member to form a spatial multi-directional stress system, having the characteristics of convention construction, reasonable structure and high strength, and the method can be used for flexibly solving the consolidation problem for structural members in high-rise buildings with large space and large span.

Description

technical field [0001] The invention relates to the reinforcement field of building structures (boards, beams, columns, walls, etc.), in particular to a reinforcement method for inclined composite structures. Background technique [0002] The existing concrete building reinforcement methods mainly include enlarging section method, outsourcing steel method, prestressing method, adding fulcrum method, pasting carbon fiber material reinforcement method and so on. The above method is reasonable and effective for dealing with beams, columns, or small areas to be reinforced in general buildings and low-span frame structures, but for high-rise buildings and long-span frame composite structural members such as: shear walls, The reinforcement of floors, beams, columns, etc. has disadvantages such as low bearing capacity, inconvenient construction, and great impact on production, life, and headroom. In order to avoid the above-mentioned shortcomings, the steel strip welding method is...

Problems solved by technology

The above method is reasonable and effective for dealing with beams, columns, or small areas to be reinforced in general buildings and low-span frame structures, but for high-rise buildings and long-span frame composite structural members such as: shear walls, The reinforcement of floors, beams, columns, etc. has disadvantages such as low bearing capacity, inconvenient construction, and great impact on production, life, and headroom.

In order to avoid the above-mentioned shortcomings, the steel strip welding method is often used in the existing reinforcement projects to deal with the above-mentioned concrete buildings to be reinforced. Chisel off, so that the internal section steel is exposed, and then start from the exposed section steel at both ends and weld the reinforcing steel belt section by section along the surface of the concrete building to be reinforced. Steel strips form the overall stressed structure. In long-term engineering practice, it is found that when this reinforcement method is used to deal with some high-rise, long-span and other special-shaped buildings to be reinforced, because the joint welds at both ends cannot meet the design requirements, there is a reinforced structural strength. The shortcomings of poor and improper force, and when the steel concrete member and the concrete building to be reinforced are at a certain angle of inclination, it will cause inconvenience to the construction due to the limitation of the operating space
