The invention provides a main tower lower cross beam support pre-pressing device and a pre-pressing method thereof, and belongs to the technical field of civil engineering construction devices. The device specifically comprises a stand column, a cross beam, a tensioning mechanism, a transmission mechanism, a rotary driving mechanism and a bottom supporting frame. The stand column is arranged belowthe cross beam to support the cross beam; the tensioning mechanism is arranged below the cross beam; a mounting hole is arranged in the cross beam; the tensioning mechanism penetrates through the mounting hole and extends to an upper part of the cross beam; a top size of the tensioning mechanism is greater than an aperture of the mounting hole; and the tensioning mechanism is further connected with the transmission mechanism, the transmission mechanism is connected to the bottom supporting frame, the stand column penetrates through the bottom supporting frame, the rotary driving mechanism isconnected to the transmission mechanism, a vertically-downward pulling force is applied to the cross beam through the transmission mechanism and the tensioning mechanism, and a vertically-downward pre-pressing force is applied to the stand column through the cross beam. According to the main tower lower cross beam support pre-pressing device, stress balance of the two sides of the stand column canbe guaranteed, pressure borne by the stand column is ensured to be vertically downward, and a pre-pressing force applying process is simple.
本发明提出了一种主塔下横梁支架预压装置及其预压方法，属于土木工程施工装置技术领域，其具体包括立柱、横梁、拉紧机构、传动机构、旋转驱动机构和底支撑架，立柱设置在横梁下方对横梁进行支撑，拉紧机构设置在横梁下方，横梁上设置有安装孔，拉紧机构穿过安装孔延伸至横梁上方，拉紧机构的顶部尺寸大于安装孔的孔径，拉紧机构还与传动机构连接，传动机构连接在底支撑架上，底支撑架上还穿过有立柱，旋转驱动机构连接在传动机构上，通过传动机构和拉紧机构给横梁施加垂直向下的拉力，通过横梁给立柱施加垂直向下的预压力。本发明主塔下横梁支架预压装置能够保证立柱两侧的受力平衡，保证立柱受到的压力也是垂直向下的，预压力施加过程简单。
