Cantilever beam construction and installation method and novel cantilever beam structure
The invention provides a cantilever beam construction and installation method and a novel cantilever beam structure.The cantilever beam construction and installation method comprises the following steps that a floor slab is chiseled away, and a column head surrounding steel plate, an upper annular plate, a lower annular plate and a beam head side wall steel plate are welded to one another, surround the intersection portion of a column body and a plurality of concrete beams and are welded to reinforcing steel bars of the floor slab; a gap between the steel plate and concrete is densely filled with grouting materials, so that the structural strength of the connecting end of the cantilever steel beam is greatly enhanced, the cantilever steel beam is installed on the column head surrounding steel plate through the lug plates, the rectangular connecting plates and the high-strength bolts, the structure is stable, the construction technology is simple, no chemical adhesive is needed, and the construction cost is reduced. The risk of anchoring failure in a long-term load state is avoided; secondly, steel bars or chemical anchor bolts need to be planted on the beam columns, and the situation that construction is affected due to dense steel bars in a beam column joint area is avoided; and finally, the process is standardized in operation, the construction process is slightly influenced by human factors, and the construction quality is effectively guaranteed.
本发明提供了一种悬挑梁施工安装方法及新型悬挑梁结构，悬挑梁施工安装方法包括以下步骤：通过凿除楼板并将柱头围套钢板、上环板、下环板和梁头侧壁钢板相互焊接并围合在柱体与多根混凝土梁的交叉部位且与楼板的钢筋焊接，再用灌浆料将钢板与混凝土之间的缝隙填充密实从而将悬挑钢梁的连接端结构强度大大加强，再通过耳板、矩形连接板和高强螺栓将悬挑钢梁安装在柱头围套钢板，不仅结构稳定，施工工艺简单，且无需使用化学胶粘剂，避免长期负荷状态下出现锚固失效的风险；其次，需要在梁柱上植筋或者化学锚栓，避免梁柱节点区钢筋密集，影响施工；最后，该工艺标准化操作，施工工艺受人为因素影响小，有效保证施工质量。
