Construction technology for connecting steel beams in foundation ring construction
The invention provides a construction process for connecting a steel beam in foundation ring construction, which comprises the following steps of: pre-embedding and assembling a support body for supporting a foundation ring on the periphery of the foundation ring in advance; the connecting steel beam is located between the foundation ring and the supporting body, and the connecting steel beam is welded to the foundation ring and the supporting body so as to achieve installation of the foundation ring; during welding, the connecting steel beam and the foundation ring are welded firstly, and after welding is completed and cooling is conducted, the connecting steel beam and the supporting body on the outer side of the foundation ring are welded; when the connecting steel beam and the foundation ring are welded, welding is conducted from bottom to top in the height direction; the number of the connecting steel beams is multiple, the foundation ring serves as the symmetry center, the multiple connecting steel beams are symmetrically constructed, and in the symmetrical construction process, every two symmetrical connecting steel beams are constructed at the same time. According to the method, melting and other reactions caused by high-temperature welding are fully considered, the height change of the foundation ring is reduced to the maximum extent, and the requirement for the levelness of 2 mm is met.
本发明提供了一种基础环施工中连接钢梁的施工工艺，包括以下步骤：于基础环外周，预先将支撑基础环的支撑体预埋装配；连接钢梁，所述连接钢梁位于基础环与支撑体之间，连接钢梁分别与基础环和支撑体焊接，以实现对于基础环的安装；焊接时，按照先焊接连接钢梁与基础环，焊接完成并冷却后，再将连接钢梁与基础环外侧的支撑体进行焊接的顺序进行焊接；连接钢梁与基础环焊接时，沿高度方向，按照从下至上的方向，进行焊接；连接钢梁为若干个，以基础环为对称中心，若干个连接钢梁对称施工，且对称施工中，对称的两个连接钢梁同时施工。本发明充分考虑高温焊接引起的熔化等反应，最大限度的减少了基础环高度变化，使其满足2mm的水平度要求。
