Post-cast strip galvanized steel pipe supporting frame back-jacking construction method
The invention discloses a back-to-top construction method for a post-cast strip galvanized steel pipe supporting frame, and relates to the technical field of fixed buildings, which comprises the following steps: 1, welding a supporting plate at the top end of a supporting column; 2, a plurality of holes are formed in the positions, on the two sides of the post-cast strip, of the pouring formwork at intervals along the post-cast strip; 3, supporting columns are installed, supporting plates are embedded in the holes, the supporting plates are flush with the pouring formworks around the holes, and asphalt felt is laid; 4, concrete is poured around the bottom ends of the supporting columns; 5, before the supporting plate is installed, the disc body with the positioning pin is arranged on the supporting column in a sleeving mode; after the supporting column is installed, the two ends of the connecting rod are connected with the positioning pins, and the middle of the connecting rod is connected to the concrete pier through the pull rod. After other steel pipe formwork supports, pouring formworks and platforms are detached, the supporting frame can serve as a temporary support of the post-pouring belt, the pouring formworks on the two sides of the post-pouring belt are not occupied, and the turnover rate of materials can be increased. The supporting columns are reinforced through the connecting rods, the pull rods and the like, and the stability and firmness of the supporting frame are improved.
本发明公开了一种后浇带镀锌钢管支撑架回顶施工方法，涉及固定建筑技术领域，包括以下步骤：1.支撑柱顶端焊接支撑板；2.在后浇带两侧的浇筑模板上沿后浇带间隔开设若干孔洞；3.安装支撑柱，将支撑板嵌于孔洞，使支撑板与孔洞周围浇筑模板齐平，铺设油毡；4.围绕支撑柱的底端浇筑混凝土；5.在支撑板安装前，将带有定位销的盘体套于支撑柱；支撑柱安装后，将连接杆两端与定位销连接，用拉杆将连接杆中部连接于混凝土墩。其他钢管支模架、浇筑模板及平台拆除后，本发明的支撑架可以作为后浇带的临时支撑,不占用后浇带两侧的浇筑模板，可以提高材料的周转率。支撑柱之间通过连接杆、拉杆等进行加固，提高支撑架的稳定性和牢固性。
