Construction method, device for installing pier top part bottom die of beam bridge
The invention discloses a construction method, device for a bottom die at the top part of a beam bridge mounting pier, which are characterized in that the peripheral range of a gap area is limited by a temporary support, and a plurality of groups of test blocks, distribution beams, reinforcing steel bars, steel pipes, square timbers, bamboo plywood and plastic cloth of a permanent support are used as the whole bottom die structure of cantilever beam casting; each group of test blocks is laid on the top of the mounting pier, the distribution beams are arranged on each group of test blocks in the temporary support in the gap area, the distribution beams and the steel bars on the two sides of the distribution beams are tightly attached to the test blocks and welded between the adjacent distribution beams through the steel pipes, the tensile strength of the distribution beams is improved, and river sand or sand bags are adopted as stabilizing materials. Supporting is stable, the situation that the bottom die deforms in the pouring process is eradicated, construction safety risks are reduced, the casting quality of the cantilever beam can be improved, dismantling is easy, the material reutilization rate is high, and the construction progress is fast.
本发明公开了梁式桥安装墩顶部分底模的施工方法及其装置，本发明用临时支座限位空隙区域的周边范围，采用永久支座的多组试块、分配梁、钢筋、钢管、方木、竹胶板，塑料布、作为悬臂梁涛筑的整个底模结构，本发明在安装墩顶部铺设置每组试块，将分配梁置在空隙区域的临时支座内的每组试块上，分配梁及其两侧的钢筋均紧贴试块，并通过钢管焊接于相邻分配梁之间，提高分配梁的抗拉伸强度，且采用河砂或砂袋作为稳固材料。本发明支撑稳固，杜绝了浇筑过程中底模变形的情况发生，减少了施工安全风险，可以提高悬臂梁涛筑的质量，易拆除，材料重复利用高，施工进度快。
