Method for assembling prefabricated part reinforcing column through concrete
The invention provides a method for assembling a prefabricated part reinforcing column through concrete. The method comprises the steps that a painting layer or a cushion layer on the surface of a component is chiseled away to a concrete base layer for treatment; the surface of the base layer and the surface of a concrete prefabricated part are coated with adhesives; the concrete prefabricated part is fixed; the concrete prefabricated part is clamped with a clamp, and is properly pressurized; impurities in a hole channel are removed, a prestressed steel strand is manually pulled, and the steel strand is tensioned and fixed; pipeline grouting and anchor sealing are conducted; and after the adhesive is cured, the clamp is dismantled. Vertical steel bars of the concrete prefabricated parts are connected through a sleeve grouting technology, and fine aggregate concrete or grouting materials are poured at connecting positions of the prefabricated parts and anchor sealing positions for sealing treatment. According to the method, a fabricated concrete column and brick column reinforcing method is provided, the method is good in corrosion resistance and fire resistance, saves energy and is environmentally friendly, the method can effectively improve the mechanical property of the concrete column, the reinforcing effect is guaranteed, standardized fabricated parts are adopted in the construction process, on-site wet operation is greatly reduced, the labor consumption is reduced, the construction efficiency is improved, the cost is reduced, and the construction period is shortened.
本发明提供了一种采用混凝土装配预制件加固柱的方法；包括：凿除构件表面的粉刷层或垫层至混凝土基层进行处理；基层表面及混凝土预制件表面上涂胶粘剂；将混凝土预制件固定；用夹具夹紧，并适当加压；清除孔道内杂物，将预应力钢绞线人工穿束，张拉钢绞线并固定；进行管道压浆和封锚；胶粘剂进行固化后，拆除夹具。将混凝土预制件竖向钢筋采用套筒灌浆技术进行连接，预制件连接部位及封锚位置处浇筑细石混凝土或灌浆料进行封闭处理。本发明提供一种采用装配式，抗腐蚀、耐火性能好、节能环保的混凝土柱、砖柱加固方法，该方法可有效提高混凝土柱力学性能，保证加固效果，施工过程采用标准化装配预制件，大幅度减少现场湿作业，操作便利、减少人工消耗量、提高施工效率、降低成本、节约工期。
