Gantry pier capping beam pre-pressing method
The invention relates to the field of prepressing, and discloses a portal pier capping beam prepressing method which comprises the following steps: step 1, preparing a reaction frame, putting a jack between the reaction frame and a stress component, and connecting the reaction frame and the stress component by using a connecting piece; secondly, a jack is started, and the reaction frame and the stress component are jacked open according to the design requirement; thirdly, after the prepressing result meets the design requirement, the stress component on the reaction frame is taken down, and the stress component is fixed to the upper end of the supporting piece.
本发明涉及预压领域，公开了门架墩盖梁预压方法，包括以下步骤：步骤一、准备反力架，将千斤顶放在反力架和受力构件之间，用连接件连接反力架和受力构件；步骤二、启动千斤顶，根据设计要求顶开反力架和受力构件；步骤三、预压结果按满足设计要求后，取下反力架上的受力构件，将受力构件固定在支撑件上端。
