Description
技术领域 technical field
本实用新型涉及建筑技术领域，尤其是指一种悬挑钢梁穿墙结构。 The utility model relates to the technical field of buildings, in particular to a wall-penetrating structure of cantilevered steel beams.
背景技术 Background technique
随着建筑施工扣件式钢管脚手架安全技术规范JGJ130-2011标准在2011年01月28日的发布，至2011年12月1日实施。经过将近一年的过渡期，对重大危险项悬挑架规范有了进一步的规范要求。其中，对于悬挑脚手架工字钢拉环，其型钢悬挑固定端应采用2个（对）及以上U型钢拉环或锚固螺栓与建筑结构梁板固定，U型钢筋拉环或锚固螺栓应预埋至混凝土梁底板层钢筋位置，并应与混凝土梁、板底层钢筋焊接或者绑扎牢固，其锚固长度应符合现行国家标准《混凝土结构设计规范》GB50010中钢筋锚固的规定。在锚固环上设置两根1.5m长直径为18mmHRB335的钢筋，如梁板处设有≥18mm钢筋时可不另外加。现有的做法是悬挑钢梁完成后，是直接将U型钢筋切割，如此造成了材料浪费，进而增加了施工成本。 With the release of the JGJ130-2011 safety technical specification for fastener-type steel pipe scaffolding in construction on January 28, 2011, it will be implemented on December 1, 2011. After a transition period of nearly one year, there are further specification requirements for the specification of cantilever frames for major hazard items. Among them, for the I-shaped steel pull ring of the cantilevered scaffold, the cantilevered fixed end of the shaped steel should be fixed with two (pairs) or more U-shaped steel pull rings or anchor bolts and the building structure beam plate, and the U-shaped steel bar pull ring or anchor bolts should be It should be pre-buried to the position of the steel bars at the bottom of the concrete beam, and should be welded or bound firmly with the steel bars at the bottom of the concrete beam and slab. The anchorage length should meet the current national standard "Code for Design of Concrete Structures" GB50010. Set two 1.5m long and 18mm HRB335 steel bars on the anchor ring, if there is a ≥18mm steel bar at the beam plate, no additional addition is required. The existing method is to directly cut the U-shaped steel bar after the cantilevered steel beam is completed, which causes material waste and increases the construction cost.
