Ultra-high-performance concrete ribbed sandwich floor and manufacturing method thereof

Abstract

The invention relates to the field of prefabricated buildings, and discloses an ultra-high-performance concrete ribbed sandwich floor and a manufacturing method thereof. The ultra-high-performance concrete ribbed sandwich floor comprises a UHPC bottom plate and a UHPC top plate, multiple UHPC short columns and UHPC ribs are distributed uniformly between the UHPC bottom plate and the UHPC top plate, first longitudinal reinforcements are distributed uniformly in the UHPC bottom plate, second longitudinal reinforcements are distributed uniformly in the UHPC top plate, vertical reinforcements arearranged in the UHPC short columns respectively, the upper end of each vertical reinforcement is fixed on the corresponding second longitudinal reinforcement, and the lower end of the corresponding vertical reinforcement is fixed on the corresponding first longitudinal reinforcement. The ultra-high-performance concrete ribbed sandwich floor and the manufacturing method thereof have the advantagesthat the bottom plate, the top plate, the ribs and the short columns are all made from a UHPC material, the UHPC's characteristics of high intensity, high tenacity and high durability are fully utilized to form an ultra-high-performance concrete ribbed sandwich floor structure, the structure can give full play to the high performance of the UHPC material, reduce the self-weight of the structure, reduce the construction difficulty, improve the durability of the structure, and reduce the difficulty of later management and maintenance.

Description

technical field [0001] The invention relates to the field of prefabricated buildings, in particular to an ultra-high performance concrete ribbed sandwich floor slab and a manufacturing method thereof. Background technique [0002] Prefabricated buildings refer to buildings assembled from prefabricated parts on site. With the development of modern industrial technology, building houses can be manufactured in batches and in sets like machine production. Just transport the prefabricated building components to the construction site and assemble them. my country's current construction industry is still at a relatively low level of development - high energy consumption, low level of mechanization, etc. The construction industry urgently needs to face transformation and upgrading, change the development mode, improve the level of industrialization development, and promote energy conservation and emission reduction in the construction field. [0003] As one of the main structural ...

AI Technical Summary

Problems solved by technology

At present, ordinary reinforced concrete is the main construction material for prefabricated floor slabs, but traditional ordinary concrete structure floors have disadvantages such as heavy weight, average durability, and easy leakage of joints; steel ribbed sandwich floors are light in structure and can be cut freely. It has obvious advantages in use, but it is not fire-resistant. In buildings with special fire protection requirements, the steel structure must be protected with refractory materials to improve the fire resistance level; in the environment of humid and corrosive media, the steel structure is prone to corrosion, generally take Regular maintenance by means of derusting, galvanizing, coating, etc.; the price of stainless steel ribbed sandwich floor slabs is higher
