In order to solve the problem, building materials replacing sand materials are being sought, and the ocean is rich in aggregate and water resources, so that the building materials can be applied to ocean engineering construction. However, corrosive ions in the marine aggregate can have a severe corrosive effect on the steel bar, thereby affecting the durability of the structure. This problem limits the large-scale development and utilization of marine resources. Meanwhile, the marine concrete structure is cast in situ on site, the construction process is complicated, the construction period is long, the efficiency is low, the building quality is difficult to ensure, and serious resource waste and energy consumption exist.

However, the traditional rib connection mode at the joint of the beam and the column of the assembled component is to connect the ribs and then pour the ribs into a whole. The connecting mode is high in construction difficulty and low in efficiency, and the hysteresis performance of the assembled node is poor and the shock resistance is poor.

Compared with the prior art, the utility model has the following beneficial technical effects:
The connecting node is formed by embedding a connecting plate prefabricated in marine concrete into a connecting piece clamping plate to form strong connection.

The full FRP material has higher corrosion resistance, improves the durability of the structure, is manufactured in factories, can realize industrialized mass production, has high structural integrity, and can customize the dimension and specification according to different engineering requirements.
The clamping plates and the stiffening ribs inside the rectangular pipes in the connecting piece provide vertical and lateral support for the interconnection of the precast concrete beams and columns, and meanwhile, the connecting pieces are fixedly connected through the anchor bolts, so that the lateral bending of the plane and the torsional deformation of the end parts of the beam heads are effectively limited, and the overall stability of the cross beam is improved. By arranging the annular connecting plate, the integrity of the connecting structure is enhanced, the shearing stress at part of the nodes is born, and the structural strength of the whole structure is improved.
