The invention discloses a 3D-printed hollow truss floor slab and a construction method thereof. The 3D-printed hollow truss floor slab comprises a plurality of prefabricated floor slab units with a hollow truss structure and a plurality of concrete composite layers arranged on the top surfaces of the prefabricated floor slab units, wherein reinforcing cavities are formed in the two ends of each truss structure, and the reinforcing cavities are filled with concrete. A truss system is applied to a floor slab system and can be integrally printed to be formed by adopting a 3D printer, the property of a 3D printing material is fully achieved, stress is more reasonable, the hollow truss floor slab is smaller in self-weight, and the adopted material is greener and more environmentally friendly; in the forming process of the floor slab, the automation degree is high, the floor slab can be formed without needing any templates, the technology is simple, on-site operation is little, a large quantity of labor and materials are saved, and no building garbage is generated in the production process.
Description
technical field [0001] The invention relates to the field of construction, in particular to a hidden beam structure in a 3D printed truss hollow floor slab. Background technique [0002] In all building structures, the floor slab is the main component bearing the functional load, the core of the building to realize its architectural function, and an important part of the building structure system, which plays a very important role in the integrity and comfort of the structure. effect. However, at this stage, the vast majority of buildings use reinforced concrete floor slabs, which have the disadvantages of heavy weight, complicated construction technology, and many on-site operations. At the same time, there are common quality problems such as cracking and water leakage. With the application of 3D printing technology in the field of construction, especially the material properties of 3D printing technology architectural inks have been greatly improved, which provides the po...
