Beam plate inclined hoisting technology
The invention provides a beam plate inclined hoisting technology, and relates to the technical field of building construction. The equipment comprises a bridge girder erection machine, a first crown block and a second crown block, wherein front supporting legs and rear supporting legs are arranged at the two ends of the bottom face of the bridge erecting machine, middle supporting legs are arranged in the middle of the bottom face of the bridge erecting machine, a bridge cover beam is arranged at the bottom of the bridge erecting machine, and a first crown block and a second crown block are arranged on the top face of the bridge erecting machine. A hoisted first hoisting beam piece is arranged on the top surfaces of the capping beam in the middle of the bridge girder erection machine and the capping beam on one side; the middle supporting leg and the rear supporting leg can be supported on the first hoisting beam piece; second hoisting beam pieces are arranged at the bottom of the bridge girder erection machine; a bridge erecting machine is adopted for double-hoisting-point hoisting, and the under-bridge space at the bridge site and the space within the range of the bridge erecting machine are utilized, so that the installation of the second hoisting beam piece is completed through transverse synchronous operation and longitudinal differential operation. The problem that individual piers are not completed due to the influence of demolition of expropriated land, rod line migration and the like is solved; in addition, due to the fact that the bridge is long and needs to be hoisted in a segmented mode, when a girder transporting line on the bridge is interrupted, under the condition that the original appearance of the land outside the red line is not damaged, girder plate hoisting does not need to expropriate the land outside the red line for arranging a girder lifting station; therefore, the original ecology and environment are protected to the maximum extent, and the beam plate hoisting problem is solved. The method has good economic benefits, social benefits and environmental protection benefits.
本发明提供一种梁板倾斜吊装技术，涉及建筑施工技术领域，包括架桥机，第一天车和第二天车，架桥机底面两端设有前支腿和后支腿，架桥机底面中间位置设有中支腿，架桥机底部有桥梁盖梁，架桥机顶面设有第一天车和第二天车，架桥机中间位置处的盖梁与一侧的盖梁顶面设有已吊装的第一吊装梁片，中支腿和后支腿可实现支撑在第一吊装梁片上，架桥机底部有第二吊装梁片，采用架桥机双吊点起吊，利用桥位处的桥下空间和架桥机范围内的空间，通过横向同步操作、纵向差异操作，完成第二吊装梁片的安装，旨在解决因受征地拆迁、杆线迁移等原因影响，个别桥墩未完成；或因桥梁较长，需分段吊装等，桥上运梁线路中断时，在不破坏红线外土地原貌的情况下的梁板吊装问题，无需征用红线外土地设置提梁站，最大限度的保护原有生态和环境，并解决了梁板吊装问题，具有良好的经济效益、社会效益和环保效益。
