Foundation pit first precast concrete supporting system connecting structure
The invention relates to a foundation pit first precast concrete supporting system connecting structure which is characterized in that a top beam is a precast top beam, a first concrete support is a precast first concrete support, the precast top beam is connected with a fender post, the precast top beam is provided with an I-shaped groove with steps, and the I-shaped groove is connected with the fender post. The end of the prefabricated first concrete support is in an I shape matched with the I-shaped groove, and the end of the prefabricated first concrete support is supported in the I-shaped groove and anchored to the prefabricated top beam. The method has the advantages that the fender post top pre-embedded steel plate and the prefabricated crown beam pre-embedded steel plate are adopted, and connection of the two components is achieved through welding of the #-shaped steel plate; the prefabricated top beam and the prefabricated first concrete support are connected through anchor bolts; the foundation pit first concrete supporting system has the advantages of being few in construction steps, simple in process, low in manufacturing cost and capable of being repeatedly used.
本发明涉及一种基坑首道预制混凝土支撑系统连接结构，所述冠梁为预制冠梁，所述首道混凝土支撑为预制首道混凝土支撑，所述预制冠梁与所述围护桩连接，所述预制冠梁上设置有具有台阶的工字形凹槽，所述预制首道混凝土支撑的端部为与所述工字形凹槽相匹配的工字形，所述预制首道混凝土支撑的端部支撑在所述工字形凹槽内并锚固于所述预制冠梁。本发明的优点是：采用围护桩顶预埋钢板、预制冠梁预埋钢板并通过井字形钢板焊接实现两种构件的连接；采用锚栓实现预制冠梁与预制首道混凝土支撑的连接；实现基坑首道混凝土支撑系统快速安装及拆除，具有施工步骤少、工艺简洁、造价低、可重复使用的特点。
