Problems solved by technology

However, the floor laminated slab will increase the weight of the floor slab and the increase is relatively large, which reduces the seismic capacity of the original structure. At the same time, the force of the foundation foundation increases, which will cause the possibility of reinforcement of the foundation foundation.

Embodiment Construction

[0019] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0020] Such as Figure 1-4 As shown, a reinforced concrete beam-slab structure with post-mounted steel continuous beams is mainly used in a reinforced concrete frame structure. In the reinforced concrete frame structure, the original beam 1 and the original floor 2 are included. The present invention is Reinforcement on the original beam 1 and the original floor 2, the main idea is to use steel beams to reinforce the original floor 2 and the original beam 1 continuously. The advantage of this method is that it will not damage the original beam 1 or The original floor 2 causes too much damage, and the span of the original floor 2 is shortened so as to improve the bearing capacity and stiffness deformation capacity.

[0021] The reinforced structure in this embodiment includes a steel structure welded and fixed in a factory and a steel structure welded and fix...

Abstract

The invention discloses a reinforced concrete beam and slab structure of a rear steel structure continuous beam. The structure comprises multiple reinforcing beams which are spliced from head to tail,the reinforcing beams are located on the low positions of original floors, the ends of the reinforcing beams are fixed to the side faces of adjacent original beams, the head and the tail between theadjacent reinforcing beams are spliced and fixed through splicing parts, the splicing parts cross the tops of adjacent original floors of the two sides of the original beams, and the splicing parts are spliced and fixed with a reinforcing beam through through holes formed in the original floors. In the reinforced concrete frame structure, the self weight can be reduced, and the anti-bearing capacity of the original beams and the original floors can be improved.

Description

technical field [0001] The invention relates to the technical field of beam reinforcement, in particular to a reinforced concrete beam-slab structure with a rear steel continuous beam. Background technique [0002] According to the policy requirements of "Four Sections-Environmental Protection" advocated by the state and the improvement of people's living and public environment, the transformation and reinforcement of existing buildings is an inevitable trend of social development. From recent observations on the existing reinforced concrete frame structure There are many renovations, most of which are due to the upgrading and renovation of building functions. The transformation of the use function is to add large equipment on the floor, add a large swimming pool to the floor, and a theater entertainment place. Its transformation has a great impact on the bearing capacity and earthquake resistance of the original structure. Due to the increase of load and the change of the...
