The invention relates to the field of civil building construction operation, in particular to the field of operation of a connecting joint between concrete columns. A prefabricated concrete column connecting joint structure is characterized by comprising an upper section of connecting column and a lower section of connecting column connected through screw bolts, wherein each connecting column comprises a pair of flat plates in horizontal arrangement and a group of reinforcing ribs connected with the two flat plates. With the design, parts of the structure can be prefabricated in capable factories and then conveyed to a construction operation site for connection and concrete casting, so that the operation is convenient, and the quality is also guaranteed.
Description
technical field [0001] The invention relates to the field of civil engineering construction operations, in particular to the field of design of connection nodes between concrete columns. Background technique [0002] At present, the joint connection types between concrete columns mainly include sleeve connection and grout-anchor connection: the cost of sleeve connection is too high, and the quality of grouting is easily affected by the on-site operating environment, and whether the grouting is full cannot be checked one by one; The quality of nodes mostly depends on the operation level of on-site workers, and the connection quality cannot be verified one by one. Contents of the invention [0003] The object of the present invention is to provide a prefabricated component connecting node with low cost, mature performance and easy quality control. [0004] In order to achieve the above object, the present invention is achieved in that: [0005] A connection node struct...
