Research on application of pre-stressed parts and joints in Beijing Agricultural Science City
Prefabricated concrete industrial buildings have the problems of low application of stereotyped industrial products and low industrialization efficiency of envelope structure.Therefore,large-span pre-stressed parts and exterior wallboard fast-fitting joints are important applications and research directions in this field.Combined with the Beijing Agricultural Science City project,the applicable law of span-load-component modulus was analyzed.Based on the characteristics of self-cutting bottom bearing anchor bolt,a prefabricated hollow exterior wallboard all-dry fast-fitting joint was developed.Based on the genetic algorithm,the intelligent module for rapid layout of pre-stressed parts of the shaped slab was developed.The results show that the module of the parts is highly matched with the functional space scale,all the prefabricated slabs adopt the shaped pre-stressed parts,the industrial collaborative integration of design-production-installation is realized and the carbon emissions of floor components per unit area are effectively reduced,the efficiency and quality of prefabricated slab design are improved.
