Steel bar bending mechanism and method for house bridge construction

Abstract

The invention discloses a steel bar bending mechanism and method for house bridge construction. The mechanism comprises a bottom plate, the outer wall of a first connection rod is fixedly sleeved witha fixing barrel, the outer wall of a second connection rod is rotationally sleeved with a pressing roller, a first motor is fixedly installed on the back face of a second side plate through a base, one side of the fixing barrel is provided with a rolling limiting device located on the upper surface of the bottom plate, a tooth plate is arranged on the upper surface of a sliding rail, a gear is inengaged connection with one side of the top of the tooth plate, a clamping device is arranged on the top of a fixing plate, the other side of a first side plate is provided with a polishing device, and the second side plate is provided with a cleaning device. By means of the arranging way of the pressing roller, one end of a steel bar is bent and mixed into concrete, high bond stress can still beobtained, therefore, the steel bar is prevented from being loosened in building concrete, the other end of the steel bar is polished and sharpened, and therefore the steel bar can be conveniently inserted into the concrete.

Description

technical field [0001] The invention relates to the construction field, in particular to a steel bar bending mechanism and a bending method for building and bridge construction. Background technique [0002] Steel bars have a wide range of uses and are almost an indispensable basic material in modern construction. The production lines of steel mills and rolling mills manufacture ordinary steel and rebar products of various specifications. Among them, there is a production line that is composed of multiple steel bars that are more than ten meters long and weighs several tons in a bundle. Most of these super-long steel bars are used in the construction industry, which plays a role in the strength of buildings. It plays an important role, it is not only used in China, but also exported to overseas. [0003] In the use of steel bars, there are generally two problems. One is that the surface of the first-class steel bars is smooth and the concrete has insufficient grip. The oth...

Problems solved by technology

[0003] In the use of steel bars, there are generally two problems. One is that the surface of the first-grade steel bars is smooth and the concrete has insufficient grip. The other is that both ends of the steel bars are flat and it is difficult to insert the steel bars into the ground or concrete.
