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.

Abstract

The invention discloses a steel plate regenerative composite wall and a construction method thereof. Holes are reserved on front and back corresponding positions of a front steel plate and a back steel plate of the steel plate regenerative composite wall, bolts pass through the reserved holes to connect the two steel plates, concrete is filled between the two steel plates, the concrete comprises new concrete and one or more waste concrete blocks, and the new concrete is filled among the waste concrete blocks and between the waste concrete blocks and the steel plates; the mass ratio of the waste concrete blocks to the new concrete is 1.4 to 1.1; and the diameter of the waste concrete block is more than 50 millimeters. The steel plate regenerative composite wall is suitable for a building structure, has the characteristics of large side rigidity resistance, good ductility, high bearing capacity and the like, has stable hysteresis performance and large absorbed energy in destructive process, can reduce large usage amount of templates, and can use the waste concrete to reach the aim of environmental protection, energy saving and discharge reduction.

Description

technical field [0001] The invention relates to a novel wall body, in particular to a steel plate recycled mixed wall and a construction method thereof, and belongs to the technical field of structural engineering. 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 scientifically u...
