Embodiment Construction
[0031] The present invention will be further described below in conjunction with specific embodiments.
[0032] Such as figure 1 As shown, a light steel frame-main reinforcement type single-row reinforcement recycled concrete shear wall structure, the combined structure is composed of end curved main reinforcement type single row steel mesh (1), thin steel sheet (2), main reinforcement type single row It consists of a recycled concrete shear wall (3), light steel beams (4), light steel columns (5), lug plates (6), and bolts (7) with row reinforcement.
[0033] The single-row reinforcement mesh sheet (1) with curved main reinforcement at the end, and the distribution distance of the single-row reinforcement with the main reinforcement type is 200mm-300mm; the single-row reinforcement mesh with curved main reinforcement at the end (1) is located in the middle of the wallboard thickness to prevent Eccentric force.
[0034] The thin steel sheet (2) is welded around the bent main...

Abstract
The invention discloses a light steel side frame and main rib type single-row reinforcement recycled-concrete shear wall and a construction method, and belongs to the field of civil engineering. A main rib type single-row reinforcement recycled-concrete shear wall, a light steel beam and a light steel column are prefabricated by a factory and are assembled in field. The main rib type single-row reinforcement recycled-concrete shear wall and a light steel frame are connected through ear plates thereon. The main rib type single-row reinforcement recycled-concrete shear wall and the light steel frame are taken as enclosure and lateral force resisting members, so that sufficient bearing force is provided during construction and usage; in a stress process, light steel and light wall components are mutually coordinated and bear the force commonly; furthermore, a design construction of joint connection is reasonable, and the force transmission is reliable. The light steel side frame and main rib type single-row reinforcement recycled-concrete shear wall combines main rib type single-row reinforcement recycled-concrete shear wall and light steel frame joint connection construction techniques, a prefabricated assembly type house technique and a recycled concrete technique, and is suitable for a multilayer building structure.
Description
technical field [0001] The invention relates to a light steel frame-main reinforcement type single-row reinforced concrete shear wall and a method thereof, which belong to the technical field of construction engineering. Background technique [0002] my country has a vast territory and a large population. Most buildings are located in earthquake zones, and most of them are masonry structures or frame-filled wall structures, which have poor earthquake resistance. On May 12, 2008, the magnitude 8.0 Wenchuan earthquake caused 16 provinces (municipalities, autonomous regions), more than 417 counties (cities, districts), 4,624 towns, and 46,574 villages in Sichuan, Gansu, Shaanxi, and Chongqing to be affected to varying degrees. The affected area was about 440,000 km2. In this earthquake, 69,227 people were killed, 374,643 people were injured, 17,923 people were missing, and the direct economic loss reached 845.1 billion yuan. The direct cause of casualties was the collapse of ho...
