Problems solved by technology

However, the above-mentioned treatment is not only cumbersome, but also consumes a lot of energy. In addition, a large amount of water, cement, sand and energy are still consumed in the preparation process of recycled aggregate concrete. Therefore, a new recycling strategy for concrete waste has emerged, namely From a more macroscopic point of view (block or segment level rather than aggregate level), the strategy of recycling waste concrete components has been researched on steel pipe recycled composite components, recycled mixed reinforced concrete beams, recycled mixed composite floors, etc. to report

Abstract

The invention discloses a beam slab node of a renewable hybrid combined floor slab made of U-shaped steel-encased renewable hybrid beam and a construction method thereof. The node comprises a node domain, a supporting plate, a shear plate, a plurality of anti-shear studs and a plurality of negative bearing ribs. The supporting plate and the shear plate are arranged at a connection part of the renewable hybrid combined floor slab and the node domain, the renewable hybrid combined floor slab consists of a profiled steel plate and renewable hybrid concrete, the U-shaped steel-encased renewable hybrid beam consists of U-shaped encasing steel and renewable hybrid concrete, the profiled steel plate of the renewable hybrid combined floor slab is welded with the supporting plate through the anti-shear studs, the end plate of the profiled steel plate is welded with a sealing plate or welded with the U-shaped encasing steel, the supporting plate is welded with the U-shaped encasing steel, the shear plate is arranged under the supporting plate and is welded with the supporting plate and the U-shaped encasing steel, and the upper part of the node domain is provided with the negative bearing ribs. The node and the construction method have the advantages of good safety and reliability, convenient construction, environmental protection, energy conservation and emission reduction.

Description

technical field [0001] The invention relates to the technical field of concrete waste recycling, in particular to a U-shaped outsourcing steel recycled mixed beam recycled mixed combined floor beam-slab node and a construction method thereof. Background technique [0002] At present, most of the concrete solid waste generated by the demolition of old buildings in my country is directly transported to the suburbs for stacking, while the concrete needed for new buildings is completely made of new cement, gravel, river sand and other materials. This not only consumes a lot of resources, but also causes serious environmental hazards. For this reason, how to scientifically use the concrete solid waste generated by the demolition of old buildings to minimize the consumption of new cement, gravel, river sand and other materials in new buildings has become a key issue for the entire construction industry to practice "environmental protection, energy saving, and emission reduction". ...
