Solid web type RPC (Reactive Powder Concrete) framework-concrete combined structure

Abstract

The invention discloses a solid web type RPC (Reactive Powder Concrete) framework-concrete combined structure. The structure comprises an RPC framework, a reinforcement net which wraps the RPC framework and is fixed and formed through longitudinal reinforcing steel bars and annular reinforcing steel bars, and concrete which fills in the RPC framework and between the RPC framework and the reinforcement net and wraps the reinforcement net; the RPC framework (1) is of a cross structure. According to the solid web type RPC framework-concrete combined structure, the RPC replaces the commonly-used metal material to be used as the main material of the framework, so that the problem of inevitable corrosion of metal materials can be overcome, and as a result, the durability of the framework concrete structure can be greatly improved; the construction defect at the combining surface of the framework and wrapped concrete can be reduced, the compactness of the structure can be improved, and the bearing capacity of the whole RPC framework-concrete combined structure is improved; compared with steel, the RPC is small in energy consumption and low in price; compared with a steel framework concrete combined structure, the RPC frame-concrete combined structure is green, economic and sustainable; the solid web type RPC framework-concrete combined structure is small in manufacturing technology index, simple in process, wide in applicable scope, low in cost, and easy to be popularized and applied.

Description

technical field [0001] The invention relates to the construction field of construction engineering composition structures, in particular to a solid-belly RPC skeleton-concrete composite structure. Background technique [0002] With the continuous development of society and the advancement of science and technology, people have put forward higher requirements for the living transportation environment, comfortable housing, and office conditions. The construction industry, as the construction of the above-mentioned environment, bears a considerable part of the responsibility, especially in terms of fast, efficient and safe construction, and ensuring high quality and high quantity of buildings. [0003] The steel reinforced concrete composite structure is a composite structure formed by embedding section steel in reinforced concrete. This structure has the characteristics of high rigidity, high bearing capacity and good fire resistance. However, the steel-reinforced concrete co...

AI Technical Summary

Problems solved by technology

However, the steel-reinforced concrete composite structure is equipped with I-beams, channel steels, H-beams and cross-beams made of steel plates. The manufacturing process is complicated and the technical indicators are high. At the same time, due to the relatively high price of steel, the energy consumption of smelting and forming is relatively high. High, resulting in high cost of steel reinforced concrete composite structure and unsustainable development, and because the internal steel structure and outsourcing concrete are heterogeneous materials, there are gaps, cavities and other defects at the joint surface of the two. In special environments, The internal section steel will be corroded and form rust swelling effect, which will further weaken the bonding effect between the outsourcing concrete and the internal section steel, making it difficult to fully realize the "joint bearing" function of the steel reinforced concrete composite structure, and also make the structure unable to achieve Load capacity and stiffness required for design state
