Tower column cross beam support ground pre-pressing device and method
The invention relates to a tower column cross beam support ground pre-pressing device and method and relates to the technical field of bridge construction. The support comprises a plurality of truss pieces, wherein a pre-pressing device is used for pre-pressing a test piece, and the test piece comprises two truss pieces which are in central symmetry and are connected; the pre-pressing device comprises a support and a plurality of pre-pressing mechanisms, wherein the support is used for supporting the test piece; each pre-pressing mechanism corresponds to two symmetrical nodes on the upper chord members of the two truss pieces of the test piece; two ends of the pre-pressing mechanism are used for being fixed to the two nodes correspondingly, and the pre-pressing mechanism is used for applying tensioning force to the two nodes according to the preset maximum stress of the nodes. The pre-pressing method comprises the following steps that a test piece is placed on the support; and two ends of each prepressing mechanism are fixed to the two corresponding nodes correspondingly, and tensioning force is applied to two nodes through the prepressing mechanisms according to the preset maximum stress of the nodes. The support is advantaged in that high-altitude prepressing of the support is converted into ground prepressing, strength, rigidity and stability of each truss piece are effectively inspected, and safety of beam construction is ensured.
本申请涉及一种塔柱横梁支架地面预压装置及方法，涉及桥梁施工技术领域，该支架包括多个桁片，该预压装置用于预压测试件，测试件包括两个成中心对称、且相连的桁片；该预压装置包括支座和多个预压机构，支座用于支撑测试件；每个预压机构对应测试件的两个桁片的上弦杆上相对称的两个节点；且预压机构的两端分别用于固定于两个节点上，并用于按照节点的预设最大受力，对两个节点施加张拉力。预压方法包括以下步骤：将测试件放置于支座上；将每个预压机构的两端分别固定于对应的两个节点上按照节点的预设最大受力，通过预压机构对两个节点施加张拉力。将支架的高空预压转化为地面预压，有效检验了各桁片强度、刚度和稳定性，确保横梁施工的安全。
