Embodiment Construction
[0033] The present invention will be further described below in conjunction with specific embodiments.
[0034] Such as Figure 1-5 As shown, the L-shaped frame thermal insulation formwork of the present invention has a single-row reinforced lightweight concrete wall, which includes an L-shaped reinforced concrete frame column 1, thermal insulation formwork 2, lightweight concrete wall 3, and a single row of steel bars. Skeleton; Among them, the single-row reinforcement skeleton includes horizontally distributed steel bars 4, vertically distributed steel bars 5, reinforced concrete concealed columns 6, ladder steel bars 9; grooves 7 and convex keys 8 are the occlusal structures at the joints of the thermal insulation formwork 2, and the dovetail The groove 10 is the surface structure of the thermal insulation formwork 2; the dovetail groove 10 is filled with surface mortar 11.
[0035] The L-shaped reinforced concrete special-shaped column 1 is divided into three-layer struct...

The invention relates to an L-shaped frame insulating built model single-row reinforced light concrete wall and a manufacturing method thereof, which belong to the technical field of earthquake resistance and hazardous reduction of buildings. The L-shaped frame insulating built model single-row reinforced light concrete wall provided by the invention is applicable to multi-layer buildings in rural areas; angle parts of the wall are combined together through embedded columns and tied steel bars, the shearing resistance of the wall is good, the inclination resistance of the wall is improved, and the earthquake resistance of the wall is effectively improved; as the embedded columns are as thick as the wall, the construction area is saved, and the column ridges are prevented; through effective connection of the embedded columns, the tied steel bars, the steel bars horizontally distributed in the wall, and steel bars vertically distributed in the wall, the overall earthquake resistance of the wall is improved.
Description
technical field [0001] The invention relates to an L-shaped frame thermal insulation formwork single-row reinforced lightweight concrete wall and a manufacturing method, belonging to the technical field of building earthquake resistance and disaster reduction. Background technique [0002] my country has a vast rural area and a large population. Most of the buildings are in the earthquake zone. The rural buildings are basically self-built, and the earthquake resistance is very weak. On May 12, 2008, the magnitude 8.0 Wenchuan earthquake caused 16 provinces (municipalities and autonomous regions), more than 417 counties (cities, districts), 4,624 townships, and 46,574 villages in Sichuan, Gansu, Shaanxi, and Chongqing to be affected to varying degrees. The affected area is about 440,000 km 2 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 main casualties were ...
