Abstract

The invention discloses a self-compacting regenerated block concrete composite shear wall and a construction method thereof. The self-compacting regenerated block concrete composite shear wall comprises two prefabricated concrete panels and two rectangular steel tubes, wherein the prefabricated concrete panels are oppositely arranged at a certain distance, and the rectangular steel tubes are positioned at the left sides and right sides of the prefabricated concrete panels; the prefabricated concrete panels and the rectangular steel tubes are enclosed to form a cavity in the middle, and the inner side interfaces of the prefabricated concrete panels adopt a serrated treatment mode; horizontal steel bars and vertical steel bars are arranged in the prefabricated concrete panels, and the horizontal steel bars are separately inserted into slot holes reserved in the rectangular steel tubes; and self-compacting regenerated block concrete is poured on site into the hollow parts of the cavity and the rectangular steel tubes during the construction. The self-compacting regenerated block concrete composite shear wall is convenient to install; the rectangular steel tubes and the prefabricated concrete panels are connected by inserting the horizontal steel bars in the prefabricated concrete panels into the slot holes reserved in the rectangular steel tubes, so that the connection is reliableand the integrity is good; the horizontal ultimate bearing capacity is high, the ductility is good, and the seismic performance is superior; and new and old concrete composite surfaces are not proneto cracking.

Description

technical field [0001] The invention relates to the technical field of waste concrete recycling, in particular to a self-compacting recycled block concrete composite shear wall and a construction method thereof. Background technique [0002] With the deepening of urbanization all over the world, the human demand for natural resources such as sand and stone has increased dramatically. At the same time, as the construction market in developing countries around the world continues to boom in recent years, human construction activities have produced a large amount of waste concrete, so the recycling of waste concrete has attracted widespread attention at home and abroad. Compared with recycled coarse aggregate and recycled fine aggregate, the use of larger-scale waste concrete blocks can greatly simplify the recycling process of waste concrete. [0003] Arranging the load-bearing walls in the building in a suitable position can effectively resist the horizontal load caused by w...
