Transformed crown beam, foundation pit support structure and construction method of transformed crown beam
The invention provides a transformed crown beam, a foundation pit support structure and a construction method of the transformed crown beam. The transformed crown beam comprises an existing crown beamand a heightening crown beam, and the heightening crown beam is arranged on the existing crown beam in a bar planting mode. The foundation pit support structure comprises a newly-built crown beam, the transformed crown beam and a support beam. The heightening crown beam on the newly-built crown beam and the transformed crown beam is supported by the support beam. The transformed crown beam comprises the existing crown beam and the heightening crown beam, and the heightening crown beam is arranged on the existing crown beam in a bar planting mode. Because the existing crown beam is heightenedand transformed, the heightening crown beam is connected by means of bar planting, and the transformed crown beams reach the required height. After the support beam is installed in the foundation pitsupport structure, the support beam has large bearing capacity and good supporting effect, it is guaranteed that the joint between the support beam and the heightening crown beam is safe and reliable,the foundation pit support structure is stable in force, and the foundation pit displacement control effect is good.
本发明提供一种改造冠梁、基坑围护结构及改造冠梁的施工方法，改造冠梁包括既有冠梁和接高冠梁，接高冠梁植筋于既有冠梁上。基坑围护结构包括新筑冠梁、改造冠梁、支撑梁，新筑冠梁与改造冠梁上的接高冠梁通过支撑梁支撑。其中，改造冠梁包括既有冠梁和接高冠梁，接高冠梁植筋于既有冠梁上。由于对既有冠梁进行加高改造，通过植筋的方式连接接高冠梁，使得改造后的改造冠梁达到所需的高度，使得基坑围护结构安装支撑梁后，支撑梁承载力大、支撑效果好，进而保证支撑梁与接高冠梁的节点安全可靠，基坑围护结构受力稳定，基坑位移控制效果好。
