钢结构厂棚的装配式构件化设计

目前建筑工程所使用厂棚普遍存在不可构件化拼装、适应性降低、周转率低、运输不方便、安拆速度慢现象,造成资源浪费严重等问题。为解决上述痛点,对建筑工程钢结构厂棚采用了装配式构件化方法进行设计,通过构件化和模数化设计,并根据实际应用场景不同设置调节块,增加厂棚的适应性,可以适应不同长宽场地。通过工厂化生产、法兰连接,实现快速拆装,快速运输。该结构具有良好的物理、力学性能,承载力大,不易变形;周转次数多,使用寿命长;损耗率低,具有良好的经济、社会效益。在满足结构使用要求并结合现场环境等诸多条件的基础上,设计出受力合理、抗震性好、经济耐用、可周转、适应性强的结构形式,对建筑工程实际设计意义颇深,编制绿色环保构件式厂棚设计方案和标准图集,在工程中的应用较为广泛,为建筑工程钢结构构件化设计提供参考和依据。

她凭啥让一帮大老爷们折服?——女班长贾云现场管理形象素描

2016年12月8日,当我在事迹材料上看到她是支架班的班长时,内心立刻被震撼了,我有一种眼见为实的愿望,就是立刻采访她。“作为女职工,能在支架班立足就不容易,何况还要管理一帮大老爷们.她是如何做到的啊?”我的同事们议论道。她就是山东能源枣矿集团柴里煤矿支护队支架班的贾云。在支架班,我看到那一根根长长的工字钢整齐地堆放在厂棚里。工人们都蹲在厂棚下忙碌着,处处焊花飞溅。支护队党支部书记沙金强喊了声“贾云”,贾云抬头往这边看,我才在男人堆里发现了她。短发的她个子有1.6米高,看起来身体很健壮。

Effect of terrain and building structures on the airflow in an airport

The aim of this study was to perform computational fluid dynamics (CFD) simulations on the airflows at the Hong Kong International Airport (HKIA). In particular, the effects of hangar buildings and terrain were studied to explore the effects of turbulence on flying aircraft, especially during landing. The CFD simulation showed that significant differences in wind speeds may occur between the north and the south runways on the western part of the HKIA under typhoon conditions with a strong north to northwesterly wind. Simulation also showed that the hanger buildings between the two runways on the western side and the nearby terrain could be causing the observed difference in the wind speeds. The results also indicated that these obstacles could cause significant wind speed variations at the western end of the south runway. This may affect the operation of landing aircraft. The CFD results for a typical typhoon case were analyzed and found to match the wind data recorded by an aircraft landing that day.
