A kind of high tenacity composite beam and its construction method

Abstract

The present invention proposes a high-toughness composite beam and a construction method thereof, wherein the composite beam includes a SWCP-PVA-ECC tensile side protective layer, a grid layer arranged on the protective layer, a rubber material arranged on the grid layer, and a The reinforced concrete material layer on the rubber layer. It solves the problem that ceramic waste is not rationally utilized, and the production of cement will release a large amount of carbon dioxide into the environment, which will aggravate the greenhouse effect. The present invention replaces the existing ordinary concrete with SWCP-PVA-ECC material, which can enhance the shear resistance of beams, The flexural bearing capacity can improve the impermeability of the beam, thereby reducing the maintenance and repair times of the beam and prolonging its service life. In addition, SWCP (solid waste ceramic powder) is a recycled admixture. The recycling of SWCP can not only reduce environmental pollution, but also save costs and non-renewable resources.

Description

technical field [0001] The invention specifically relates to a high-toughness composite beam and a construction method thereof, belonging to the technical fields of construction engineering and bridge engineering. Background technique [0002] Beams can enhance the integrity of the structure, and beams and columns can form the skeleton system of the structure, thereby supporting the stability of the structure. The slab is a heavy structure that directly bears the load, and the beam can effectively transfer the load on the slab to the column, and then gradually transfer it to the foundation and foundation. The bearing capacity and deformation performance of the beam will directly affect the service life of the entire structure. Therefore, there are high requirements for the material selection and construction process of the beam. [0003] China is a big country in ceramic production and consumption. According to statistics, about 10 million tons of ceramic waste is produced ...

Problems solved by technology

[0007] The present invention aims at the ceramic wastes proposed in the above-mentioned background technology, most of which are directly transported to the periphery of the city for dumping, and are not effectively utilized and in the production process of cement, a large amount of resources such as standard coal, limestone and clay will be consumed, and the production of cement will consume A large amount of carbon dioxide is released in the environment, aggravating the problem of the greenhouse effect, and a high-toughness composite beam and its construction method are provided, by using SWCP-PVA-ECC (Solid waste ceramic powder-polyvinylacetate-engineered cementitions composite) material to replace the original ordinary Soil concrete material is used for the protective layer on the tension side of the beam, so as to improve the overall tensile performance of the beam, reduce the width of cracks on the tension side, reduce permeability, reduce brittleness, and prolong service life
