Abstract

The invention discloses a device and method for manufacturing a concrete three-point bending coped beam. The device comprises a concrete three-point bending coped beam body and a concrete three-point bending coped beam wedge-shaped body. The concrete three-point bending coped beam wedge-shaped body and the concrete three-point bending coped beam body are combined together by positioning bolts to form the device for manufacturing the concrete three-point bending coped beam. The device is simple in structure, convenient to operate and high in practicality. The device which is used for manufacturing the concrete three-point bending coped beam is simple to operate, the shape of a notch is complete, and the test accuracy is high.

Description

technical field [0001] The invention relates to a device for making concrete three-point bending notched beams, and also relates to a method for manufacturing concrete three-point bending notched beams with the device for making concrete three-point bending notched beams, belonging to the technical field of concrete experiments. Background technique [0002] As the most widely used building material in the world today, concrete not only appears in ordinary buildings, but also in buildings in complex working environments, such as pressure vessels such as dams, drilling platforms and nuclear power plants, which makes people not only pay attention The basic properties of concrete such as tensile and compressive strength, fracture characteristics and failure mechanism have also been paid more and more attention by researchers. [0003] DL / T 5332-2005 "Hydraulic Concrete Fracture Test Regulations" proposes to test the fracture parameters of concrete by wedge splitting method and ...
