Prestress composite beam and masonry structure house prestress demolition method
The invention relates to the technical field of building construction, in particular to a prestressed composite beam and masonry structure house prestressed demolition method.The first aspect is that the masonry structure house prestressed demolition method comprises the following construction steps that surface scabbling is conducted on an original concrete main beam; prestressed tendons are additionally arranged; setting a horizontal operation line; shear steel bars and tie bars are additionally arranged; carrying out anchorage device reinforcement; calibrating a fixed point position; the prestressed composite beam is obtained; chiseling the outer wall of the original concrete column; the sectional area of the original concrete column is increased; a combined column is obtained; and dismantling the middle reinforced concrete column. On the second aspect, the prestressed composite beam is applied to a masonry structure house prestressed demolition method. The original building structure can be structurally transformed, and meanwhile the use safety of the building is guaranteed.
本申请涉及建筑施工的技术领域，尤其是涉及预应力组合梁及砌体结构房屋预应力拆除法，第一方面，砌体结构房屋预应力拆除法，包括如下施工步骤：对原混凝土主梁进行表面凿毛；增设预应力筋；设定水平作业线；增设剪切钢筋、拉结筋；锚具加固；定点位置校准；得到预应力组合梁；凿除原混凝土柱外壁凿毛；增大原混凝土柱的截面面积；得到组合柱；拆除中部钢筋砼柱。第二方面，预应力组合梁，应用于砌体结构房屋预应力拆除法中。能够实现对原建筑结构进行结构改造、同时保证建筑的使用安全。
