Problems solved by technology
[0002] In order to adjust the structure of the construction industry, improve the quality of construction, speed up construction, achieve energy conservation and environmental protection, and reduce project costs, the state has proposed to vigorously promote prefabricated buildings and specified specific implementation plans; It is widely used in wall structure, steel structure and steel-concrete composite structure system, which clarifies the structural system and application field of my country's prefabricated building. However, welding, grouting material pouring and testing at the construction site are not only time-consuming and laborious, but also quality acceptance is guaranteed. is not high, so we propose a prefabricated reinforced concrete column joint connection device to solve the above problems

The invention discloses a prefabricated reinforced concrete column joint connecting device. The connecting device comprises an upper prefabricated column body, wherein a plurality of upper prefabricated column main reinforcements are fixedly connected to the interior of the upper prefabricated column body, a steel column shoe body is fixedly connected to the bottoms of the upper prefabricated column main reinforcements, the steel column shoe body comprises a steel column shoe upper cover plate, the steel column shoe upper cover plate is fixedly welded to the bottoms of the upper prefabricated column main reinforcements, steel column shoe inner stiffening ribs are fixedly connected to the bottom of the steel column shoe upper cover plate, a steel column shoe lower bottom plate is fixedly connected to the bottom of the steel column shoe inner stiffening ribs, a plurality of reserved bolt holes are formed in the steel column shoe lower bottom plate, and a plurality of steel column shoe stiffening ribs are fixedly connected to the side wall of the steel column shoe inner stiffening ribs. Compared with the prior art, the steel column shoe, steel bar welding, drilling and steel bar end screw thread machining procedures are all prefabricated and completed in a factory, the steel column shoe is high in standardization degree and convenient to produce in batches, and compared with a traditional mode, the problems of on-site welding, grouting material pouring, detection and the like are thoroughly solved.
Description
technical field [0001] The invention relates to the technical field of construction engineering, in particular to a prefabricated reinforced concrete column node connection device. Background technique [0002] In order to adjust the structure of the construction industry, improve the quality of construction, speed up construction, achieve energy conservation and environmental protection, and reduce project costs, the state has proposed to vigorously promote prefabricated buildings and specified specific implementation plans; It is widely used in wall structure, steel structure and steel-concrete composite structure system, which clarifies the structural system and application field of my country's prefabricated building. However, welding, grouting material pouring and testing at the construction site are not only time-consuming and laborious, but also quality acceptance is guaranteed. Therefore, we propose a prefabricated reinforced concrete column joint connection device to ...
