Construction solution for additionally arranging upright column at end part of pure cantilever beam
The invention discloses a construction solution for additionally arranging an upright column at the end part of a pure cantilever beam. The construction solution is used in the condition that the upright column only relates to structural beams with one ends overhung at the corresponding positions of the upper layer and the lower layer of a building, when an external cantilever beam needs to be detached from an internal beam of a lower layer structure and reserved, the stress and anchoring length of the pure cantilever beam at the overhanging part do not meet the requirements, and the requirements are difficult to meet by reinforcing the pure cantilever beam, according to the upright column and the construction method, the concrete upright column is hung from the lower portion of the end part of the upper-layer cantilever beam, the upright column is used for transmitting force of the lower-layer pure cantilever beam to the upper-portion cantilever beam, and if the upper-layer cantilever beam does not meet the stress requirement, the stress requirement can be met through reinforcement. The construction solution has the advantages that the current situation of building facade transformation can be reserved, lower supporting columns of the cantilever beam are omitted, frontage space is guaranteed, and the higher wind and snow resistance and the like are still achieved.
本发明公开了一种在纯悬挑梁端部增设吊柱的施工方案。该吊柱仅涉及建筑上下层对应位置都有一端悬挑的结构梁，下层结构内部梁需拆除外部悬挑梁保留时，悬挑部位纯悬挑梁受力及锚固长度不满足要求，并且通过在自身上加固很难满足要求的情况下使用。上述所示吊柱及施工方法为：从上层悬挑梁端部下挂做一根混凝土吊柱，利用此吊柱将下层纯悬挑梁力传递给上部悬挑梁，若上层悬挑梁不满足受力要求，可通过加固来满足。本发明具有可保留改造建筑外立面现状，省略悬挑梁下部支柱保证临街空间，但仍具有较强的抗风雪能力等特点。
