Description
技术领域Technical field
本实用新型涉及悬挑支模架技术领域,具体为一种悬挑支模架体系。The utility model relates to the technical field of cantilever formwork, specifically a cantilever formwork system.
背景技术Background technique
随着建筑行业的不断发展,钢筋混凝土悬挑结构也越来越多,当悬挑结构标高相对较低时支模架可以采用落地式满堂支撑架体系;当标高较高时落地式满堂支撑架体系将不在适用。此时可以采用悬挑工字钢支撑架体系,传统的悬挑工字钢结构受力较小,一般适用于悬挑脚手架,无法适用于钢筋混凝土悬挑结构的支模架体系。With the continuous development of the construction industry, there are more and more reinforced concrete cantilever structures. When the elevation of the cantilever structure is relatively low, the formwork can use a floor-standing full-hall support frame system; when the elevation is higher, the floor-standing full-hall support frame can be used. The system will no longer apply. At this time, a cantilevered I-beam support frame system can be used. The traditional cantilevered I-beam structure has small stress and is generally suitable for cantilever scaffolding, but cannot be applied to the formwork system of reinforced concrete cantilevered structures.
现有技术中,专利申请号为201520743757.X,公开的一种用于高空悬挑结构的悬挑型钢支模架,包括截面呈“工”型的悬挑型钢梁、混凝土结构件、支模架和模板,混凝土结构件与悬挑型钢梁的底端沿竖直方向抵压配合,悬挑型钢梁上设有支模架,支模架间铺设有模板;在混凝土构件中还设有一下端预埋于混凝土构件中的U型螺栓,还包括一压板,压板上设有螺纹孔,U型螺栓竖直顶端穿过一压板的螺纹孔后分别与一螺帽锁紧连接,所述压板与悬挑型钢梁的顶端沿竖直方向抵压配合,本实用新型充分利用原有结构条件和型钢自身承载能力,在高空悬挑构件下一层按照悬挑外架的方式安装悬挑型钢梁,在悬挑型钢梁上搭设钢管支撑架、安装模板,施工高空悬挑钢筋混凝土结构。In the existing technology, the patent application number is 201520743757. Formwork and formwork, the concrete structural components and the bottom ends of the cantilevered steel beams are pressed together in the vertical direction, the cantilevered steel beams are provided with formwork frames, and formwork is laid between the formwork frames; there are also It is provided with a U-shaped bolt whose lower end is embedded in the concrete component, and also includes a pressure plate. The pressure plate is provided with a threaded hole. The vertical top of the U-shaped bolt passes through the threaded hole of a pressure plate and is then locked and connected with a nut. The pressure plate and the top of the cantilevered steel beam are pressed together in the vertical direction. This utility model makes full use of the original structural conditions and the load-bearing capacity of the steel beam itself, and installs the cantilevered outer frame on the layer below the high-altitude cantilevered component. For cantilevered steel beams, steel pipe supports are erected on the cantilevered steel beams and formwork is installed to construct high-altitude cantilevered reinforced concrete structures.
钢筋混凝土悬挑结构的支撑架,在实际使用过程存在一些缺陷,由于悬挑型钢梁分散布置,其间距受主体结构安装位置的限制,当其上部安装的满堂钢管支撑时,钢管支撑底端不便在悬挑型钢梁上落脚,给钢管支模架的施工带来不便,若悬挑支模架整体结构不够稳固,存在很大安全隐患。The support frame of the reinforced concrete cantilever structure has some defects in the actual use process. Since the cantilevered steel beams are dispersedly arranged, their spacing is limited by the installation position of the main structure. When the upper part is supported by a full-length steel pipe, the bottom end of the steel pipe is supported. It is inconvenient to stand on the cantilevered steel beams, which brings inconvenience to the construction of the steel pipe formwork. If the overall structure of the cantilevered formwork is not stable enough, there will be great safety risks.
