Embodiment Construction

[0034] The specific implementation method of the present invention will be further described below in conjunction with the accompanying drawings.

[0035] refer to Figure 1-Figure 8 , a prefabricated assembled unreinforced concrete frame, including prefabricated concrete node columns 15, prefabricated concrete beams 16, steel connectors 17 and grouting pipes 20.

[0036] The prefabricated concrete node columns 15 and prefabricated concrete beams 16 are all poured from ultra-high ductility polyethylene fiber concrete (refer to Table 1 for the mix ratio). It has been verified by tests that it has the advantages of high strength, good ductility, corrosion resistance, etc., and can directly applied to engineering structures.

[0037] Table 1 Reference mix ratio of ultra-high ductility polyethylene fiber concrete (kg / m3)

[0038]

[0039] The middle part of the precast concrete node column 15 is prefabricated with a small section beam 2 for connecting the precast concrete bea...

Abstract

The invention provides a prefabricated non-reinforced concrete framework. The prefabricated non-reinforced concrete framework is composed of prefabricated concrete joint columns, prefabricated concrete beams, steel connecting parts and grouting pipes. The prefabricated concrete joint columns and the prefabricated concrete beams are formed by pouring polyethylene fiber concrete. The polyethylene fiber concrete is formed by mixing cement, sand, water, coal ash, water reducer and polyethylene fibers. The invention further provides a construction method of the prefabricated non-reinforced concreteframework. Use of rebars is avoided while the strength and the ductility of components are guaranteed, splicing joints and the construction method are adopted, resources can be effectively saved, andthe site construction efficiency and the quality safety level can be improved.

Description

technical field [0001] The invention relates to building structures, in particular to a prefabricated unreinforced concrete frame and a construction method thereof. Background technique [0002] The prefabricated components of the existing prefabricated reinforced concrete frame have many construction procedures, the connection and assembly procedures on the construction site are cumbersome, and the construction quality is difficult to guarantee; in addition, because the reinforced concrete components are mostly in the working state with cracks, corrosive media are easy to invade the inside of the components, causing corrosion. Stressed steel bars will destroy the bearing capacity and durability of the structure, endangering the safety of people's lives and property. Therefore, the traditional prefabricated reinforced concrete frame has many shortcomings in terms of production efficiency, quality and safety. If the use of steel bars in concrete frame members can be avoided,...
