Cross beam construction method using temporary prestress as temporary support
The invention discloses a cross beam construction method using temporary prestress as a temporary support. The method is characterized by comprising the following steps that A, according to a cross beam design drawing, cross beam pouring is divided into a first-time concrete pouring part and a second-time concrete pouring part, and the first-time concrete pouring part and the second-time concretepouring part are divided according to the height of a cross beam; B, a cast-in-place support is erected, a first-time concrete pouring part is completed according to the designed load, and a pluralityof embedded parts of the profile steel support are embedded in the first-time concrete pouring part; compared with the prior art, the poured concrete cross beam part participates in stress through temporary prestress setting, the situation that a subsequent cast-in-place support participates in bearing is reduced or even not needed, the problem that the cross beam construction needs the cast-in-place support with very high bearing capacity is solved, on the other hand, the profile steel support can be repeatedly used, materials are saved, and structural stress is clear.
一种利用临时预应力作为临时支撑的横梁施工方法，其特征在于，包括以下步骤：步骤A:根据横梁设计图纸，将横梁浇筑分为第一次混凝土浇筑部分和第二次混凝土浇筑部分，第一次混凝土浇筑部分和第二次混凝土浇筑部分根据横梁的高度进行分割；步骤B：搭设现浇支架，根据设计载荷完成第一次混凝土浇筑部分，并在第一次混凝土浇筑部分内预埋型钢支架的多个预埋件；与现有技术相比，通过临时预应力设置使得已浇筑部分混凝土横梁部分参与受力，降低甚至是无需后续的现浇支架参与承重，解决了横梁施工需要很高承载力的现浇支架问题，另一方面，可以重复利用型钢支架，节省材料，结构受力清晰。
