Swivel bridge bottom formwork support system and quick dismounting method
The swivel bridge bottom formwork support system comprises a plurality of rows of supporting pier sets, a plurality of right-angle triangular supports and a plurality of winches, the supporting pier sets and I-shaped steel connecting pieces form a stable support system, and the bevel edges of the right-angle triangular supports arranged side by side above support the low formwork of a swivel bridge in a matched mode. High-strength support is provided for the low formwork of the middle swivel part of the large-tonnage swivel bridge, the displacement deformation phenomenon is avoided, the pouring construction quality of the large-tonnage swivel bridge body is guaranteed, the pouring construction safety is improved, a bearing jacking device is designed between the pier columns, and the bearing jacking device is convenient to use. During formwork dismantling operation, the device can effectively release pressure borne by the right-angle triangular support, the right-angle triangular support is pulled out of the bridge bottom through the winch at the end of the supporting beam, rapid dismantling of a low formwork support system is achieved, and the dismantling construction efficiency is improved.
一种转体桥梁底模支架体系及快速拆卸方法，包括若干排支撑墩组、若干个直角三角支架和若干个卷扬机，支撑墩组以及工字钢连接件形成了稳固的支座体系，通过上方并排布置的直角三角支架的斜边匹配支撑住转体桥的低模，为大吨位转体桥中间转体部的低模提供高强度支撑，避免出现位移变形现象，保证大吨位转体桥体的浇筑施工质量，提升浇筑施工的安全性，并在墩柱之间设计了承托顶升装置，拆除模作业时该装置能够有效释放掉直角三角支架受到的压力，通过支撑梁端部的卷扬机将直角三角支架拉拽出桥底，实现了低模支架体系快速拆卸，提高拆卸施工效率。
