The utility model discloses a structure for artificially breaking an internal support beam, which belongs to the technical field of building construction, and comprises the following steps: a full hall scaffolding operation platform is set up, and a concrete layered backfilling is adopted between the exterior wall of the basement and the inside of the foundation pit, and the main beam is set on both sides of the grid column before the support of the main beam is removed. Before removing concrete, the concrete beam is bored with drill rod before breaking the concrete, the concrete beam is expanded by concrete extender, and the internal support beam is demolished artificially. The order of dismantling is to dismantle the beams from both ends of the beam to the beam near the wall of the foundation pit and from the bottom to the bottom of the foundation pit. Dismantle the beam. The utility model adopts the lower cost than the gold steel wire saw, which is convenient to remove the concrete from the concrete, and is not restricted by the site. At the same time, the safety risk of the structure is relatively small by its own operation and vibration.
【技术实现步骤摘要】
一种用于人工破除内支撑梁的结构
本技术属于房屋建筑施工
技术介绍
混凝土内支撑梁的拆除主要有金钢绳锯切割、静力爆破、挖掘机进行破除的方法。采用金钢绳锯的方式施工成本相对较高,切割时自身操作及对结构的安全风险相对较大,腰梁部分因一面靠近基坑护壁桩,绳锯无法操作,其它切割下来的混凝土结构吊运及运输较为困难。静力爆破对施工专业队伍要求较高,操作专业度高,对周边环境及结构安全有影响。挖掘机破除噪音污染严重,震动较大,对结构安全造成影响。
技术实现思路
本技术的目的在于:提出一种用于人工破除内支撑梁的结构,采用该结构进行人工破除内支撑梁,成本较金钢绳锯的低,剔除下来的混凝土建渣清运方便,不受场地限制,同时自身操作及震动对结构的安全风险相对较小。本技术目的通过下述技术方案来实现:一种用于人工破除内支撑梁的结构,包括基坑内由内支撑梁和格构柱共同构成的内支撑,还包括操作平台、混凝土层、隔震缝和扩张孔,操作平台布置于楼板和内支撑梁之间,混凝土层填充于地下室外墙与基坑内侧之间,隔震缝设于内支撑梁与格构柱两侧,每一内支撑梁上均开设有若干个扩张孔。作为选择,操作平台包括扣件式钢管搭设的满堂脚手架,在满堂脚手架的操作面上沿内支撑梁铺设的木架板,以及沿木架板外侧搭设的栏杆。作为进一步选择,满堂脚手架的立杆纵横间距为1.5m、步距2m,栏杆高度为1.1m。作为选择,隔振缝设置于内支撑梁上位于格构柱两侧1±0.2m处,隔震缝切入钢筋混凝土保护层深度5±1cm。作为选择,混凝土层由上下若干混凝土分层构成,每层混凝土分层厚度不超过1m。前述本技术主方案及其各进一步选择方案可以自由组合以形成 ...
