Connecting piece for connecting reinforced concrete members, manufacturing method of connecting piece and construction method

Abstract

The invention discloses a connecting piece for connecting reinforced concrete members, a manufacturing method of the connecting piece and a construction method. The connecting piece comprises a first connecting piece body and a second connecting piece body. One end of the first connecting piece body is provided with a locating groove sunken into the surface of the first connecting piece body. The other end of the first connecting piece body is in mechanical connection with a reinforced concrete member to be connected. One end of the second connecting piece body is clamped in the locating groove and can move along the locating groove. The other end of the second connecting piece body is in mechanical connection with another reinforced concrete member to be connected. The manufacturing method of the connecting piece includes the first step of carrying out water cutting on a steel plate to form the first connecting piece body, drilling a hole in the threaded hole position and then drilling another hole in the locating groove position, the second step of carrying out milling to form the locating groove, the third step of installing the second connecting piece body and the fourth step of welding a block board. The construction method includes the steps that the second connecting piece body is connected; the first connecting piece body is connected with a connecting reinforcing steel bar through a sleeve, and then the connecting reinforcing steel bar is connected with the reinforced concrete member; the relative deviation positions and the deviation distance between the reinforced concrete members are adjusted; concrete is poured at the connection positions.

Description

technical field [0001] The invention relates to a connection of building materials, in particular to a connection piece used for the connection of reinforced concrete components, a manufacturing method and a construction method. Background technique [0002] In the prefabricated reinforced concrete structure, because the steel bars cannot rotate in the prefabricated components, it is difficult to mechanically connect the steel bars. At present, mechanical connection methods such as lap connection, welding connection or extrusion sleeve are mostly used for the connection of steel bars. Among them, the lap connection of steel bars is the simplest, but the lapped steel bars are long, and the waste of steel bars is serious. The connection of prefabricated components has a large amount of casting ; The construction of welding connection or extrusion sleeve mechanical connection is more complicated, and there are inaccurate positioning and inconvenient construction.
