Problems solved by technology
[0003] 1. The steel bar at the joint exceeds a certain length of the concrete prefabricated part. After binding the steel bars at both ends, cast concrete at the joint to fix the concrete connection, but it has the following defects: complicated operation, poor reliability, difficult operation, labor cost high and low efficiency
[0004] 2. Steel plates or steel structures are installed at the joints of concrete prefabricated parts, and the two concrete prefabricated parts are connected by welding steel plates or steel structures. However, the efficiency of welding steel plates or steel structures is low, and the product quality is difficult to guarantee due to human factors.

The invention discloses a concrete prefabricated part connecting structure, a connecting piece and a connecting method. The concrete connecting piece comprises a connecting piece body, wherein a chamber and a reduced passage communicated with the chamber are formed in the connecting piece body. The reduced passage is communicated with the external world, the reduced passage is gradually reduced along a direction far away from the chamber, an elastic part is arranged in the chamber, two or more than two locking pieces are arranged in the reduced passage, one end of the elastic part is connected with the connecting piece body and the other end of the elastic part is connected with the locking pieces. After a connecting rod is inserted into the reduced passage, the locking pieces respectively press against the connecting piece body and the connecting rod. By adopting the concrete connecting piece disclosed by the invention, two concrete prefabricated parts are simple to connect, the two concrete prefabricated parts can be quickly connected, and the connecting stability is high.
Description
technical field [0001] The invention relates to the technical field of connection of prestressed concrete, in particular to a connection structure of prefabricated concrete parts, a connection piece and a connection method. Background technique [0002] At present, the connection of concrete prefabricated parts often has the following two methods: [0003] 1. The steel bar at the joint exceeds a certain length of the concrete prefabricated part. After binding the steel bars at both ends, cast concrete at the joint to fix the concrete connection, but it has the following defects: complicated operation, poor reliability, difficult operation, labor cost high and low efficiency. [0004] 2. Steel plates or steel structures are installed at the joints of the concrete prefabricated parts, and the two concrete prefabricated parts are connected by welding the steel plates or steel structures. However, the efficiency of welding the steel plates or steel structures is low, and it is ...
