Abstract

The invention discloses a novel concrete fracture toughness pouring mold which comprises a combined steel mold plate, a joint-cutting steel plate and a plurality of bolts. The combined steel mold plate comprises a bottom plate, a short edge side plate and a long edge side plate. The short edge side plate and the long edge side plate are mounted on the upper plane of the bottom plate and are movably connected to the bottom plate through chutes. The short edge side plate comprises a first short edge side plate and a second short edge side plate. The long edge side plate comprises a first long edge side plate and a second long edge side plate. The first short edge side plate and the second short edge side plate are separately attached to the left and right side walls of the first and second long edge side plates through fixed bolts. A reserved gap is formed in the middle position of the side wall of the second long edge side plate. The joint-cutting steel plate is arranged in the second long edge side plate in a penetrating manner through the reserved gap. For joint cutting of a concrete test block, a joint-cutting tool is not adopted, so that the manufacturing step is simplified, andthe labor intensity and dust and noise pollution caused by independent joint cutting are eliminated.

Description

technical field [0001] The invention relates to the field of concrete characteristic testing, in particular to a novel concrete fracture toughness pouring mold. Background technique [0002] In engineering design, the basic characteristics of building materials should be tested. Fracture toughness is one of the important characteristics of concrete materials. Higher fracture toughness can ensure better ductility of the structure. The determination of fracture toughness is usually determined by test methods. The conventional method is to pour the concrete test block first, and then use a cutting tool to create cracks of a certain width and depth on the side of the test block. Sometimes it will cause damage to the test block concrete, which will cause a large test error. Contents of the invention [0003] The purpose of the present invention is to provide a novel concrete fracture toughness pouring mold to solve the problems raised in the above-mentioned background technol...
