摘 要 长信大厦是为了满足公差旅游、休闲、外出的需要,而为旅客提供住宿、参观、社交、娱乐等多种服务,位于湖南省沅江市繁华地段的一座多功能建筑。建筑面积为12943.9m2, 本建筑最高层为八层,建筑高度为33.50m。该建筑地下一层为车库、配电室、水泵房、设备间等,室内地面标高为-3.50m;地上八层,一层为商铺,层高为6.0m;二层为茶艺大厅和包房,层高为5.0m;三层为厨房、包房和餐厅,层高为5.0m;四、五层为客房、会议室、办公室,层高为3.0m;六、七层为客房、会议室,层高为3.0m;八层为多功能大厅和仓库,层高为3.0m;具体布置如工程图纸所示。水源由市政管网提供,常年压力为Mpa。 水源由市政给水管网供给,该设计给水系统采用分区供水方式,低区为地下一层至地上三层,高区为四层至八层,高低区均采用水泵水箱联合供水。 消防系统采用消火栓灭火系统、自动喷淋灭火系统相结合的方式,消火栓灭火系统管网布置成环状,在建筑外侧设两个水泵接合器,当水量不足时可由室外消防车通过水泵接合器供水。 自动喷淋灭火系统采用独立的湿式自动喷水灭火系统,该系统具有灭火及时,效率高的优点,但也存在缺陷,由于管网中充有有压水,当渗漏时会损坏建筑和影响建筑物的使用。 该建筑的功能决定采用集中热水供应,由于集中热水供应系统可以集中设置加热和其他设备,便于集中维护管理;加热设备热效率高,热水成本较低;各热水使用场所不必设置加热装置,占用总建筑面积较少;使用较为方便舒适Abstract JinTian Building is located in the downtown area of Yuanjiang City, Hunan Province.
