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 reinforced gangue concrete beam-column joint template and its application. The template includes a beam bottom mold, a column bottom mold, two beam end molds, two column end molds, four "L"-shaped side molds, four Partition plate and two anti-overflow plates; beam bottom formwork and column bottom formwork cross in parallel to form a "ten" shape, two beam end forms are set at the front and rear ends of the beam bottom formwork, and two column end formworks are set at the column bottom formwork Four "L"-shaped side forms are set between two adjacent beam end forms and column end forms, and the two ends of the side forms are respectively connected with the vertical edges of beam end formwork and column end formwork. The partitions are vertically and correspondingly clamped between the opposite side forms near the intersection of the beam bottom formwork and the column bottom formwork. Two vertical slits are respectively arranged on both sides of the partition plate in the vertical direction. An anti-overflow plate is respectively covered and arranged between the upper end of the partition plate and the upper end of the side mold. The formwork has simple structure and convenient assembly.
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...
