Extension of data from fire endurance tests 耐火试验数据的扩展
From the test results , suggestion that negative moment reinforcement should run through the specimens to postpone the crack ' s appearance and improve the specimens " fire endurance are also proposed 由此提出了拉通板顶负筋的建议,以延缓横向贯通裂缝的出现,达到保护预应力筋和提高连续板耐火性能的目的。
The main factors including concrete cover and prestressing levels which may have influence on the fire resistance of the simply - supported slabs are examined . the deflection and prestress are presented . from the results of tests , the fire endurance of the simply - supported slabs are given 在简支板的火灾行为试验研究中主要考虑了普通钢筋的保护层厚度和预应力度两个因素,主要测试了构件的挠度变化及预应力的变化,并由此得出了其耐火极限。
The vesicant material is the most key factor for the performance of the 11th coating , and then , the next is based matrix . if the dosage of based matrix is definite , increasing the dosage of vesicant material , compound material or additive will improve the fire endurance of the produced material 通过正交试验比较得出发泡材料对配方11耐火极限影响最大,其次是粘结剂;在粘结剂量一定的条件下,增加发泡材料、复合填料及助剂,均可提高涂料的耐火极限。
Suitable for the fireproofing of the skyscraper , can be suitable for such obscure steel construction in industry and civil building as the theatre , petrochemical industry , garage , oil drilling platform and large span factory building , etc . , coating plays a firing prevention and protecting role on the surface , improve the fire endurance to reach the specification of modern fire protection design 适用于高层建筑的防火,也可适用于影剧院、石油化工、汽车库、钻井平台和大跨度厂房等工业与民用建筑中的隐蔽钢结构,涂覆于表面起防火保护作用,提高耐火极限达到现代防火设计的技术要求。
