Connecting structure and connecting method for full-prefabricated assembled support-free rigid framework
The connecting structure comprises a lower prefabricated section and an upper prefabricated section, a toothed plate is arranged in the lower prefabricated section, a toothed groove is formed in the upper prefabricated section, the extending part of the toothed plate is inserted into the toothed groove, and the toothed plate is inserted into the toothed groove. An anti-falling locking piece for locking and fixing the toothed plate and the toothed groove is also arranged in the upper prefabricated section; the connecting method comprises the following steps that the toothed plates and the toothed grooves are prefabricated and machined; a toothed plate is installed in the lower prefabricated section, and a tooth groove is installed in the upper prefabricated section; sealant or mortar is smeared at the joints of the lower prefabricated sections; hoisting the upper prefabricated section, and clamping the tooth plate into the tooth groove; the anti-shearing limiting bolts are inserted and locked in sequence, and it is ensured that the clamping elastic pieces in the clamping caps clamp the clamping heads; and the concrete pin holes of the prefabricated sections are blocked through shrinkage-compensating concrete. The construction period can be shortened, the engineering quality is improved, and the method has the advantages of rapidness, environmental protection, high efficiency, high quality and the like.
本发明公开了一种用于全预制拼装无支座刚构的连接构造及连接方法，其连接构造包括下部预制节段、上部预制节段，下部预制节段中设置有齿板，上部预制节段中设置有齿槽，齿板的探出部插入到齿槽中，上部预制节段中还设置有将齿板、齿槽锁紧固定的防脱锁紧件；其连接方法，包括以下步骤：预制加工齿板、齿槽；将齿板安装到下部预制节段中，将齿槽安装到上部预制节段中；在下部预制节段的接缝处涂抹密封胶或砂浆；吊装上部预制节段，将齿板卡入齿槽内；依次将抗剪限位栓插入锁紧，确保卡位帽内的卡位弹片卡住卡头；采用补偿收缩混凝土封堵预制节段混凝土销孔。本发明可缩短了施工周期，提升了工程质量，具有快速、环保、高效、优质等优点。
