Description

Anti-cracking roof prestressed concrete double-T plate

[ technical field ] A

The utility model relates to a technical field of two T boards, especially prevent the technical field of two T boards of fracture roofing prestressed concrete.

[ background of the invention ]

A prefabricated reinforced concrete bearing member combined by plates and beams is composed of a wide panel and two narrow and high ribs. The panel is not only a transverse bearing structure, but also a pressed area of a longitudinal bearing rib. The compression area has a larger section, the neutralization shaft approaches or enters the panel, and the tension main steel bar has a larger moment arm. Therefore, the double-T plate has good structural mechanical property, definite force transmission level and simple geometric shape, and is a relatively economic bearing component which can be manufactured into a large span and a large coverage area. In the late 20 th century and 50 s, double-T panels developed in various countries throughout the world. China began to use for factory roofs and floor coverings since 1958. The building member is commonly adopted in the United states in the 60 s and becomes a common building member for building single-layer multi-span industrial factory buildings and multi-layer public and civil buildings. The dual-T plate is adopted in the countries of Canada, federal Germany, finland, UK, japan, poland Romania and the like, and the Federal Germany also has a complete set of special equipment for manufacturing the dual-T plate. However, the existing double-T plate is simple in structure and poor in anti-cracking performance, and the existing double-T plate is of an integrated structure, large in size and not easy to store and transport.
