Two-fulcrum double-layer steel corbel jacking device and installation and application method

GAO ZUOPING / ZHANG CHANG / WU BO / LIU CHUNNIAN

The invention discloses a two-fulcrum double-layer steel corbel jacking device and an installation and application method, the two-fulcrum double-layer steel corbel jacking device comprises a steel slide way device, a steel corbel device and an anti-shearing steel bar, and the application method of the installation device is simply introduced. The lower portion of the steel slideway device is reliably connected with the reinforced concrete foundation, and the upper portion is connected with the reinforced concrete column through the shear-resistant steel bar. Nuts are matched with the upper steel corbel lower shear-resistant steel bar and the lower steel corbel upper shear-resistant steel bar which are mainly stressed, so that the shear-resistant steel bars are prevented from sliding in the shear-resistant steel bar holes due to stress. By adopting the standardized design, the upper and lower steel corbels, the anti-shearing steel bars and the engineering cushion blocks are the same, and standardized production and construction are facilitated. In the application process, the jacking height is divided into a plurality of identical small-stroke heights, complex operation is changed into simple operation, operation is circulated, safety and reliability are achieved, and the design, construction and construction period is shorter compared with a newly-built building. By means of two-fulcrum double-layer steel corbel jacking, the requirement for the construction environment is lowered, the applicability is higher, and application and popularization of the jacking layer-adding technology of the frame structure building are better facilitated.

本发明公开了一种两支点双层钢牛腿顶升装置及安装应用方法，包括钢滑道装置、钢牛腿装置和抗剪钢棒，并简单介绍安装装置应用的方法。钢滑道装置下部与钢筋混凝土基础可靠连接，上部通过抗剪钢棒与钢筋混凝土柱连接。对主要受力的上钢牛腿下抗剪钢棒与下钢牛腿上抗剪钢棒上配套螺母，防止抗剪钢棒由于受力而在抗剪钢棒孔内滑动。采用标准化设计，使得上、下钢牛腿相同，抗剪钢棒相同，工程垫块相同，便于标准化生产、施工。在应用过程中，将顶升高度分为多个相同小行程高度，化繁为简，循环操作，安全可靠，相较新建建筑设计、施工，工期更短。两支点双层钢牛腿顶升降低施工环境需求，适用性更强，更有利于框架结构建筑的顶升加层技术推广应用。
