Abstract

The invention discloses a 3D (three-dimensional) printing hollow truss floor slab and a construction method thereof. The 3D printing hollow truss floor slab comprises a plurality of prefabricated floor slab units and a concrete laminated layer, the prefabricated floor slab units are provided with hollow truss structures, reinforcing cavities are formed at two ends of each truss structure and filled with concrete, and the concrete laminated layer is arranged at the tops of the prefabricated floor slab units. A truss system is applied to a floor slab system and can be integrally printed by a 3D printer, the performance of a 3D printing material is brought into full play, stress is more reasonable, the hollow truss floor slabs are light in weight, the used material is more green and environmentally friendly, the floor slabs are high in automation in the forming process and can be formed without any formworks, technology is simple, field operation is less, a large quantity of manpower and materials are saved, and building rubbishes are avoided in the production process.

Description

technical field [0001] The invention relates to the field of construction, in particular to a 3D printed truss hollow floor slab and a construction method thereof. 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...
