Externally pasted fiber layer, preparation method, underground structure and assembly type construction method
The invention discloses an externally-pasted fiber layer, a preparation method and an assembly type construction method, and belongs to the technical field of urban underground space. The externally-pasted fiber layer comprises a fiber fixing plate, a framework is connected to the lower portion of the fiber fixing plate, a plurality of parallel fiber fixing wires are arranged on the framework, and the fiber fixing wires are parallel to the fiber fixing plate and spaced from the fiber fixing plate by a set distance. Steel fibers are connected between the fiber fixing plate and the fiber fixing wires. During assembly type construction, the externally-attached fiber layer is fixed to the bottom face of the prefabricated part, the prefabricated part is installed on the fine flat strip, and the length direction of fiber fixing wires in the externally-attached fiber layer is parallel to the length direction of the fine flat strip; and non-shrinkage cement is poured in the length direction of the fiber fixing wires, and a grouting layer is formed. Due to the fact that the position of the steel fiber is fixed by the fiber fixing wire and the fiber fixing plate, and the flowing direction of the fiber fixing wire is consistent with that of the pouring material, the pouring material can fully flow, and a pouring layer with the steel fiber evenly distributed is obtained.
本发明公开了外贴纤维层及制备方法、装配式施工方法，属于城市地下空间技术领域。外贴纤维层包括：纤维固定板，纤维固定板下方连接有骨架，骨架上设置有多个互相平行的纤维固定丝，纤维固定丝平行于纤维固定板，且与纤维固定板相隔设定的距离；在纤维固定板和纤维固定丝之间连接有钢纤维。装配式施工时，将外贴纤维层固定在预制构件的底面，将预制构件安装在精平条带上，使外贴纤维层中纤维固定丝的长度方向平行于精平条带的长度方向；沿纤维固定丝的长度方向灌注无收缩性水泥，形成注浆层。由于钢纤维的位置被纤维固定丝与纤维固定板固定，且纤维固定丝与浇注材料的流动方向一致，能够使浇筑材料的充分流动，获得钢纤维均布的浇筑层。
