    摘要
  • 摘要: 整体预制夹芯墙体是集承载、保温、轻质于一体的墙体构造形式，由内外叶墙、连接件、中间保温板三部分组成，而连接件是连接夹芯保温墙体内、外叶墙及保温板的关键部件，目前市场上连接件多为进口，并且价格偏高，不利于推广。因此需要寻求一种力学及保温性能较好且价格低廉的新型连接件。选取玻璃纤维型材作为夹芯墙体连接件材料，与一般连接件相比具有无冷热桥、强度高、耐腐蚀、价格低廉的优点。对采用了棒状、板状、L型、H型、槽型连接件的夹芯保温墙体进行拉拔及剪切试验，并对夹芯墙体试件进行了热工试验，结果表明玻璃纤维具有较好的抗剪切及抗拉拔性能且保温隔热性能优良，其中槽型连接件的开裂荷载和极限荷载最大，更适合作为预制夹芯保温墙体内部连接件。
    Abstract: The prefabricated sandwich wall is a new type of wall, which integrates load-bearing, heat preservation and light weight. It consists of inner and outer leaf walls, connector and intermediate insulation board. The connector is a key component for connecting the inner and outer leaf walls and the thermal insulation boards. The current connector on the market are mostly imported from abroad, and the price is very high, it is not conducive to be widely used. Therefore, it is necessary to find a new type of connector with good mechanical properties, thermal insulation performance and low price. In the paper, glass fiber reinforced plastics profile was selected as the material of connector for the sandwich wall. Compared with the conventional connector, it showed the advantages of no cold and heat bridge, high strength, excellent corrosion resistance and low price. The pull-out and shear tests on the prefabricated sandwich wall with different types and sizes of fiberglass reinforced plastics were peformed, including rods, plates, L-section, H-section and C-section profiles. The thermal test of the sandwich wall was also carried out. The results showed that the glass fiber reinforced plastics had good shear and tensile strength as well as thermal insulation performance. The C-section connector had the largest crack-resisting load and ultimate load, which might be more suitable for the inner connector of prefabricated sandwich walls.
