Existing underground space structure toughening device and construction method
The invention discloses an existing underground space structure toughening device and a construction method, and relates to the technical field of underground space construction. The problem that an existing structure toughening method adopting steel fiber concrete pouring is not suitable for an existing underground space structure is solved. The structure comprises at least one structure reinforcing layer wrapping the outer sides of the cross beams and the stand columns; the reinforcing frames are symmetrically arranged and fixedly connected to the two sides of the crossed portion of the transverse beam and the longitudinal beam and the two sides of the crossed portion of the transverse beam, the longitudinal beam and the stand column respectively. The method comprises the steps that laying construction of first structure reinforcing layers is conducted on the upper surface and the lower surface of the cross beam respectively, annular reinforcing layers spaced by a certain distance are adopted for wrapping to form second structure reinforcing layers, the first structure reinforcing layers are laid on the outer sides of the stand columns, and the annular reinforcing layers are arranged at the positions close to beam-column joints at intervals to form the second structure reinforcing layers; and the cross beam crossing part and the beam column crossing part are supported by a bracket and are locked and fixed through a penetrating bolt.
本发明的一种既有地下空间结构增韧装置及施工方法，涉及地下空间施工技术领域。针对现有采用钢纤维混凝土浇筑的结构增韧方法不适用于既有地下空间结构的问题。它包括：包裹于横梁及立柱的外侧至少一层结构增强层；分别对称设置并固接于横向横梁和纵向横梁的交叉部位两侧，以及横向横梁、纵向横梁与立柱的交叉部位两侧的多个加固架。方法：在横梁的上表面和下表面分别进行第一结构增强层的敷设施工，并采用间隔一定距离的环向增强层进行包裹构成第二结构增强层，立柱外侧敷设第一结构增强层，并在靠近梁柱节点处间隔设置环向增强层构成第二结构增强层，在横梁交叉部位及梁柱交叉部位采用支架支撑并通过贯穿螺栓锁紧固定。
