Fabricated rectangular concrete-filled steel tube combined top beam and construction method thereof
The invention discloses a construction method of a fabricated rectangular concrete-filled steel tube combined top beam. The construction method comprises the steps that (1) earthwork is excavated to the construction elevation of the top beam, and construction of a top beam cushion layer is conducted; (2) two limiting pieces are arranged on the two sides of a supporting wall and extend in parallel in the first axis direction, a dividing piece is mounted between the two limiting pieces, the two ends of the dividing piece are connected to the two limiting pieces correspondingly, and the space between the two limiting pieces is divided into a fixed cavity through the dividing piece; and (3) concrete is poured into the fixed cavity to form a concrete limiting block. The invention further discloses the fabricated rectangular concrete-filled steel tube combined top beam. In the construction method, the limiting pieces and the dividing piece can be recycled after construction of an underground structure is completed, compared with a traditional reinforced concrete top beam, the construction cost can be saved by 30-60%, the limiting pieces and the dividing piece can be recycled, thus building waste generated during top beam dismounting is greatly reduced, and environment-friendly construction is facilitated.
本申请公开了一种装配式矩形钢管混凝土组合冠梁的施工方法，步骤为：(1)开挖土方至冠梁的施工标高，进行冠梁垫层的施工；(2)将两根限位件布置在支护墙的两侧，两根限位件沿第一轴线方向并行延伸；在两根限位件之间安装分割件，分割件的两端分别连接到一根限位件上，分割件将两根限位件之间的空间分割为固定腔；(3)在固定腔内浇注混凝土，形成混凝土限制块。本申请还公开了装配式矩形钢管混凝土组合冠梁。本申请中，限位件和分割件在完成地下结构的施工后，可以进行回收利用，与传统的钢筋混凝土冠梁相比，可以节约造价30‑60％，限位件和分割件可以回收利用，大幅度地减少拆除冠梁时，所产生的建筑垃圾，有利于环保施工。
