Problems solved by technology

However, the above-mentioned treatment process 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, it is necessary to seek a more reasonable strategy for recycling concrete waste.

Embodiment Construction

[0030] The specific implementation of the present invention will be further described below in conjunction with the drawings and embodiments.

[0031] Such as Figure 1-12 As shown, a U-shaped outsourcing steel recycled composite beam includes U-shaped outsourcing steel 1, new concrete 2, floor slab or roof slab 3, waste concrete block 4, stud connector 5, steel sheet connector 6, Longitudinal reinforcing bar 7, outer folding part 8 on the top of the U-shaped outsourcing steel side plate.

[0032] See figure 1 , the top of the side plate of the U-shaped outsourcing steel is folded outward. At this time, if a number of stud connectors are arranged at intervals along the length direction of the beam on the bottom surface inside the U-shaped outer cladding steel and the upper surface of the upper folded part of the side plate, the cross-sectional schematic diagram is shown in figure 2 , if a number of steel sheet connectors are arranged at intervals along the length direction...

Abstract

The invention discloses a U-shaped steel-encased regenerated composite beam and a construction method thereof. The U-shaped steel-encased regenerated composite beam comprises one or more disused concrete blocks, new concrete, and U-shaped encased steel, the disused concrete blocks are arranged inside the U-shaped encased steel, and the gap between the disused concrete block and the U-shaped encased steel is filled with the new concrete. The method includes the following steps: the U-shaped encased steel is made as the formwork of a beam and is integrated with the formwork of the floor slab or roof slab; a layer of new concrete is first poured into the U-shaped encased steel, then the disused concrete blocks and new concrete are alternately put into the U-shaped encased steel, tamping is utilized then to distributed the disused concrete blocks into the new concrete; steel bars of the floor slab or the roof slab are put into the formwork of the floor slab or the roof slab, and the new concrete is poured into the formwork of the floor slab or the roof slab. The invention can save a great amount of energy consumed in the processes of breaking, screening, purifying and the like for the concrete waste.

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 including waste concrete blocks 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. The resulting hazards include: ①Waste encroaching on land, polluting soil and water bodies; ②Excessive mountain quarrying destroys surface vegetation and original landforms, causing soil erosion and deterioration of the ecological environment; ③Extensive dredging of river sand destroys river beds and dams, endanger the safety of rivers; ④ cement production consumes a lot of energy and causes serious environmental pollution. For this reason, how to s...
