Embodiment Construction

[0018] The present invention will be described in detail below with reference to the accompanying drawings.

[0019] The present invention adopts the prestressed concrete double T board (hereinafter referred to as the double T board) is based on a large number of experimental studies on the stress performance (comprising its deformation, destruction and recovery performance) of the double T board, and is suitable for 6 A new type of structural component required for the roof of the basement of the civil air defense. Because prestressed concrete components are not included in the national standard "Code for Design of Civil Air Defense Basement" GB50038-2005, the present invention is an extension of the scope of application of the code and a breakthrough in design principles.

[0020] The load conditions that should be met by the 1.6 level civil air defense basement:

[0021] 1) Covering the roof with soil;

[0022] 2) Fire wheel pressure load;

[0023] 3) Under the dynamic l...

Abstract

The invention provides a prestressed concrete double T plate for an air raid shelter, which relates to a double T plate for construction. The invention can solve the problems of control parameters of prestress of a member and design principle and construction measures at the member designing stage under high load (covering soil, a fire-fighting truck or nuclear explosion shock wave equivalent load), realize factory production and greatly improve construction efficiency.

Description

technical field [0001] The invention relates to a concrete slab for building, in particular to a prestressed concrete slab suitable for civil air defense basements. Background technique [0002] The civil air defense basement is a basement with predetermined protective functions to meet the needs of civil air defense command, communication, and shelter. The design of Class B air defense basement must meet its predetermined wartime protection requirements for conventional weapons and biological and chemical weapons. The design of air defense basement must implement the policy of "long-term preparation, key construction, and combination of peacetime and wartime", and should adhere to the principle of coordinated development of civil air defense construction and economic construction, and integration with urban construction. In terms of plane layout, structure selection, ventilation and moisture protection, water supply and drainage, power supply and lighting, etc., correspond...
