投资要点:
1、规划明确钢结构比例不低于10％.
2、国家大力推行装配式建筑趋势未改
5月5日,河北省住建厅印发了《河北省装配式建筑“十三五”发展规划》,明确钢结构比例不低于10％:1)到2020年,全省装配式建筑占新建建筑面积的比例达到20％以上,其中钢结构建筑占新建建筑面积的比例不低于10％;2)到2020年,培育2个国家级装配式建筑示范城市、20个省级装配式建筑示范市(县)、30个省级装配式建筑产业基地、80个省级装配式建筑示范项目;3)计划到2025年,装配式建造方式成为主要建造方式之一,全省装配式建筑面积占新建建筑面积的比例达到30％以上;4)计划在毗邻雄安新区的保定市依托装配式建筑基地企业,打造以服务北京市、雄安新区和保定周边地区为主的装配式建筑示范园区. 相似文献

装配式建筑相较于传统的混凝土现浇建筑,具有整体性较差的特点,并由此引发了一系列问题,如墙板接缝处防水问题、钢筋混凝土结构以及钢结构的吊装出现问题、墙体注浆注意事项等.要确保装配式建筑工程施工质量,就必须对安装和使用过程进行控制,本文将结合万科某个装配式高层住宅项目为实例,对装配式建筑工程施工过程中几个易发问题的施工质量控制进行分析研究. 相似文献

Many college freshmen arrive woefully unprepared to do college work, and as disadvantaged populations continue to grow, the share of the American work force that has made it through college is expected to plummet. Many experts blame that educational failure not just on high schools but also on colleges. School & College, a special report by The Chronicle, looks at efforts to fix the system. What reforms would better prepare students for college? What should schools and colleges be doing differently? How should state and federal officials help? 相似文献

There are numbers of crossroads on our long and unpredictable life journey where we totally have no idea about which direction to choose. No matter what our decision is, we should not turn back, but face the music and go ahead instead. I am this kind of girl who always does try without regretting, one example is how I dealt with my love. 相似文献

Migration occurs behind a variety of reasons and has a great effect on the whole world. People may migrate in order to improve their economic situation, or in order to escape civil strife, persecution, and environmental disasters. The impact of migration is complex, bringing both benefits anddisadvantages. This paper briefly talks about the causes of migration, the allocation of benefits, and the ways in which individual countries and the international community deal with this important subject. 相似文献

Sister Carrie is one of the most controversial characters in American literature.Thought as a "fallen woman" firstly,she was defined as a "new woman" by some critics later. However, by digging into the motivaton behind the whole process of Carrie's "success", the relationship between Carrie and her creator (the author), the social conditions of then American, it can be found that Carrie has never been free-standing on her thought and she has never found her real-sdf even after becoming a famous actress. In a society dominated by mass consumerism Carrie is only an adherent of her own desires. She also is a representative of all those country girls flooded into cities, a symbol and a sacrifice of the urbanization of America in a time countryside was overcome by cities. 相似文献

During interview with English majors, it was found that a majority of students expressed disappointment with their experience of English literature classes. Students' dislike of learning English literature appears to be the major problem of teaching English literature in China. Reader response approach is a good way to solve this problem. In this paper, I explain the rationale behind the reader response approach, such as its origin, definition, features, assumptions, and strategies. Then I illustrate how reader response approach works as a teaching strategy by presenting several teaching models. At last I evaluate its usefuiness for teachers and present the advantages of reader response approach in Chinese context. 相似文献
