Problems solved by technology
[0007] The technical problem to be solved by the present invention: Aiming at the defects in the mechanical properties of the existing gangue concrete, the present invention provides an ECC reinforced gangue concrete beam-column joint template and its application. The template has a simple structure and is easy to assemble. The poured ECC reinforced coal gangue concrete can not only give full play to the good deformation ability and high strength and toughness of ECC materials, but also can make up for the poor crack resistance of coal gangue concrete, and promote the application of coal gangue concrete in construction projects

The invention provides an ECC (error correction code) reinforced coal gangue concrete beam-column joint template and application thereof. The template comprises a beam bottom die, a column bottom die,two beam end dies, two column end dies, four L-shaped side dies, four partition plates and two overflow prevention plates, wherein the beam bottom die and the column bottom die are crossed in parallel to form a cross shape; the two beam end dies are arranged at the front end and the rear end of the beam bottom die; the two column end dies are arranged at the left end and the right end of the column bottom die; the four L-shaped side dies are arranged between the two adjacent beam end dies and column end dies; the edges of two ends of the side dies are correspondingly connected with the vertical edges of the beam end dies and the column end dies; the four partition plates are correspondingly, vertically and correspondingly clamped between the opposite side dies close to the crossed part ofthe beam bottom die and the column bottom die; two vertical seams are correspondingly formed in two sides of the partition plates in the vertical direction; and the overflow prevention plates are correspondingly arranged between the upper ends of the two partition plates positioned on the beam bottom die and the upper ends of the side dies in a covering manner. The template is simple in structureand convenient to assemble.
Description
technical field [0001] The invention relates to the technical field of construction engineering, in particular to an ECC reinforced gangue concrete beam-column joint formwork and an application thereof. Background technique [0002] Coal gangue is the largest mining solid waste in the coal production process. The stacking of coal gangue also brings serious environmental pollution and occupation of cultivated land. Therefore, the development and utilization of coal gangue is imminent. Using coal gangue to make concrete aggregate is a reasonable way to utilize coal gangue, which is more sufficient and thorough than other recycling methods, and the economic benefits are also very significant. However, directly using coal gangue concrete in the frame structure will lead to excessive shear deformation in the joint area, wide cracks, and even concrete flakes. This is determined by the poor shear performance and low elastic modulus of coal gangue concrete. Previous earthquake dam...
