Temporary hinging and rigid connection conversion method for truss beam column
The invention belongs to the technical field of building construction, and discloses a truss beam column temporary hinging and rigid connection conversion method which comprises the steps that built-in ends are pre-embedded at the designed heights of two columns, bolt holes are formed in the built-in ends, and knuckle bearings are installed at the two ends of a truss; the truss is hoisted to the position between the two built-in ends, and the knuckle bearings are connected with the bolt holes so that the truss can be temporarily fixed to the built-in ends; and after the self-weight loading of the truss is finished, an inlaying section is arranged between the inlaying end and the end part of the truss, so that the inlaying end is fixedly connected with the truss. By means of the method, the additional bending moment in the truss construction stage can be fully unloaded through the knuckle bearing, the truss and the inlaying end are rigidly connected through the inlaying section, the design of the connecting joint of the truss and the column is simplified, the strength and rigidity of the joint can be kept consistent with those of other rod pieces in the truss, and the construction efficiency is improved. And the additional bending moment accumulated by the truss in the construction stage is prevented from being accumulated to the final use stage, so that the integral rigidity of the truss is coordinated, and the stress is uniform.
本发明属于建筑施工技术领域，公开了一种桁架梁柱临时铰接及刚接转换方法，包括：在两根柱子的设计高度预埋嵌固端，并在嵌固端开设螺栓孔，在桁架的两端安装关节轴承；将桁架吊装至两个嵌固端之间，并将关节轴承与螺栓孔连接，以将桁架临时固定于嵌固端上；在桁架自重加载完成后，通过在嵌固端和桁架端部之间设置嵌补段以将嵌固端与桁架固定连接。通过此方法，能够通过关节轴承将桁架施工阶段的附加弯矩充分卸载，且通过嵌补段将桁架与嵌固端进行刚接，简化了桁架与柱子的连接节点的设计，且节点处的强度和刚度能够与桁架中的其他杆件保持一致，避免施工阶段过程中桁架所积累的附加弯矩累积到最终使用阶段，使桁架整体刚度协调，受力均匀。
