Description

一种钢纤维石墨导电混凝土保温地暖结构
技术领域
本发明是一种钢纤维石墨导电混凝土保温地暖结构，属于地暖结构领域。
背景技术(国内外研究现状及存在的问题)
地面辐射采暖(简称地暖)，该采暖方式以整个地面光散热器，通过地板辐射层中的耐热管材或发热电缆，使整个地面均匀受热，利用地面的自身蓄热功能和热量辐射特性由下而上地进行热量的传导，最后达到供暖的目的。
传统地暖大多为3层地暖，由挤塑保温板、反射膜、地暖管组成，挤塑保温板直接平铺在原始地面上，由于原始地面不平整，保温板存在架空的情况，另外，原始地面上往往铺了强弱电线管、冷热水管，为了避免水电管将保温板架空，只能将水电管道嵌入保温板，这样，保温板的保温效果就大打折扣。另外，原始地面的湿气很容易进入保温板内，使其保温效果变得更差。并且地暖管是以热传递的形式向四周传递，由于地暖管下方保温措施做得不充分，原始地面的散热面大，与地暖管就形成了一个很大的热流面，同样原始地面与管道的温差也大，也形成了一个较大的热流温差，这就导致了传统地暖的热量散失非常严重，保温效果不尽人意，传统的取暖方式以及房屋建造方式已难以满足保温性能需求。
此外，目前所应用的大部分地暖大都使用传统的发热热源(金属类发热元件、水循环等)，少部分采用新材料也只是粗放加工工艺；同时，水暖升温缓慢，能源消耗量大，不易维修。并且仍有很多地区仍然选用如木炭取暖、小太阳取暖器等供暖方式，不仅会降低室内空气质量，污染环境，还具有安全隐患，每年都会报道出因不安全取暖方式造成的诸如一氧化碳中毒死亡甚至火灾等安全事故。
发明内容
(1)技术问题(拟解决的关键问题)
本发明是一种钢纤维石墨导电混凝土保温地暖结构，主要解决的是传统发热地板保温效果差，热量容易散失，现有发热地板使用成本较高，容易造成污染且存在一定安全隐患的问题。
(2)技术方案(技术路线)
为了解决传统发热地板保温效果差，热量容易散失，现有发热地板使用成本较高，容易造成污染且存在一定安全隐患的问题，本发明从地暖结构本身入手，提出一种钢纤维石墨导电混凝土保温地暖结构。
一种钢纤维石墨导电混凝土保温地暖结构，包括防水瓷地砖表面层、钢纤维石墨导电混凝土板、反射膜、保温层。
钢纤维石墨导电混凝土板由钢纤维、石墨粉、外加剂等经成型后制成，并与防水连接线相连。
反射膜材质为PET覆膜的镀立反射膜，具有防水防潮的作用，可有效防止热量散失；保温层材质为挤塑聚苯乙烯泡沫板(XPS板)，具有优异、持久的隔热保温性和优越的抗水、防潮性，是目前建筑业物美价廉、品质俱佳的隔热、防潮材料。采用这两种材质制成的反射膜、保温层，可有效提高整体结构的保温能力，进而加强地暖的保温效果。
本发明的安装工艺为：首先在原始地面上铺设保温层，再在保温层上铺一层反射膜后，将钢纤维石墨导电混凝土板放置于反射膜上，最后在表面铺设防水瓷地砖表面层即可。本发明在使用时，通过钢纤维石墨导电混凝土板发热传递给瓷地砖表面，从而在室内实现地面发热这一功能。
(3)有益效果(创新性)
本发明是一种钢纤维石墨导电混凝土保温地暖结构，与现有传统发热地板结构相比，具有以下优点：
1.本发明将钢纤维和石墨作为导电相材料加入混凝土中，以此作为结构中的热源，可以综合使用钢纤维优秀的力学性能和石墨优良的导电性能，得到强度高、电阻小且能满足工程需要的导电混凝土板。钢纤维石墨导电混凝土板由钢纤维、石墨粉、外加剂等经成型后制成，并与防水连接线相连。通电后，电能通过钢纤维激发并联的石墨粉产生热运动，放射出辐射能，达到辐射供暖之效果。防水连接线用于连接钢纤维石墨导电混凝土板和电源，不会外漏影响美观，同时也避免连接线与水接触发生短路或与空气接触时间长产生老化的问题，提高安全性能的同时也延长了其使用寿命。
2.本发明中，反射膜的材质为PET覆膜的镀立反射膜或者纯铝反射膜，具有防水、防潮、防腐蚀的作用。
3.本发明中，保温层材质为挤塑聚苯乙烯泡沫板，简称挤塑板，又名XPS板，可广泛应用于低温储藏地面、低温地板辅射采暖管下、泊车平台、机场跑道、高速公路等领域的防潮保温，控制地面冻胀，是目前建筑业物美价廉、品质俱佳的隔热、防潮材料。具有优异、持久的隔热保温性，优越的抗水、防潮性，防腐蚀、经久耐用性。
4.本发明中，钢纤维石墨导电混凝土板与保温层厚度为20mm，在实际应用时不占用层高。
5.本发明安装方便、快捷，只需要完成地板的铺设，不需要像传统发热地板结构一样，首先要铺设管路、电线等，然后还要覆盖一层厚厚的水泥层或泡沫塑料层，然后再在水泥层或泡沫塑料层铺设表面装饰材料。采用锁扣连接，只需要按锁扣正常铺装好地板后，线路也就自然连通，非常方便、快捷、安全。且本发明在安装及使用过程中，不会对环境造成污染，具有绿色环保的优点。
本发明的关键创新点在于综合利用了钢纤维优秀的力学性能和石墨优良的导电性能，将钢纤维和石墨结合加入混凝土中并以此作为热源，得到强度高、电阻小的导电混凝土板；反射膜与保温层成本低，保温隔热性能好，能够有效防止热量向地下散失；防水瓷地砖表面层与防水连接线在提高安全性能的同时也延长了其使用寿命，兼具安全性、实用性与经济性；安装及使用过程中不产生污染，绿色环保。
