Unbonded prestressed floor reconstruction holing construction method and supporting hanger structure
The invention provides an unbonded prestressed floor reconstruction holing construction method and a supporting hanger structure. Comprising the following steps: measuring and setting out to determine the forming position of a permanent hole in the unbonded prestressed floor; determining a setting area of a temporary hole by utilizing a building completion drawing and a detection instrument; building a construction model of unbonded prestressed floor reconstruction holing; simulating the whole process of transformation and holing through the construction model, and analyzing and determining a preset temporary hole construction sequence, a preset prestressed tendon cutting grouping and construction procedure and deflection deformation values of the unbonded prestressed floor slab in different construction states; digging temporary holes according to a preset temporary hole construction sequence; preset prestressed tendon cutting grouping and construction procedures are executed; and permanent hole construction is conducted. According to the method, the influence of each working condition on the floor slab structure is mastered through simulated working condition analysis, the optimal position and number of the temporary holes and the cutting grouping and construction procedures of the prestressed tendons are determined, and the construction efficiency is improved.
