Prestressed steel reinforced concrete double-T plate and construction method thereof

Abstract

The invention provides a prestressed steel reinforced concrete double-T plate. The prestressed steel reinforced concrete double-T plate is composed of a left rib plate, a right rib plate and a face plate, and the left rib plate is composed of a left U-shaped stirrup, a left rib plate longitudinal bar, left profile steel, a left upper flange stud, a left lower flange stud, left rib plate concrete and a left prestressed rib; the right rib plate is composed of a right U-shaped stirrup, a right rib plate longitudinal rib, right profile steel, a right upper flange stud, a right lower flange stud, right rib plate concrete and a right prestressed rib; and the face plate is composed of face plate longitudinal bars, face plate transverse bars and face plate concrete. The profile steel and the bonding prestressed tendons are arranged in the left rib plate and the right rib plate, the cross section area of the rib plates can be reduced, the concrete consumption is reduced, the self weight of the structure is reduced, the span of the double-T plate is increased, the rigidity and the bearing capacity of the double-T plate can be obviously improved, and good economic benefits are achieved. The prestressed steel reinforced concrete double-T plate is prefabricated in a factory and quickly assembled on site, and has the advantages of being convenient to construct, good in construction quality, short in construction period and the like.

Description

technical field [0001] The invention belongs to the technical field of construction, and in particular relates to a prestressed steel concrete double-T slab and a construction method thereof. Background technique [0002] Prefabricated buildings have the characteristics of high production efficiency, excellent product quality, and low environmental impact. The country and various regions have introduced various incentive policies in recent years to promote the comprehensive and rapid development of prefabricated buildings. However, in actual construction, when building large-span auditoriums, conference halls, sports facilities, etc., steel structures are still mostly used, and their anti-corrosion and fire-resistant properties are often poor, while the matching roof maintenance structure and roof waterproof insulation requirements are relatively high. , resulting in problems such as higher cost. [0003] Prestressed concrete double T-slab is a prefabricated reinforced conc...

AI Technical Summary

Problems solved by technology

However, when the ordinary prestressed concrete double T slab requires a large bearing capacity, the reinforcement of the member and the prestressed tendon will increase significantly, resulting in an increase in the cross-sectional size of the double T slab, and the arrangement of the reinforcement and prestressed tendons is more difficult.
