The existing old building is mostly a brick-concrete structure, and in order to meet the requirement of a large bay, the original bearing wall needs to be dismantled.
In the process of constructing and transforming the bottom layer or the multi-layer large space structure of the traditional house, the method of designing the reinforced concrete underpinning beam at the bottom ring beam or the plate bottom is often adopted for transforming and underpinning design. The design and construction method requires strict and uniform time for construction steps at each stage, the perpendicularity and the crack level of the wall body are abnormal easily before the concrete underpinning beam is poured, and the cracks and the deflection of the wall and the underpinning beam are beyond the standard limit after the concrete is poured. This is mainly because, when the concrete underpinning beam is set and poured, the non-uniformity and strength of the concrete material do not reach the designed strength completely, so that the wall is easy to crack when the upper wall load is transmitted to the underpinning beam, the beam deflection is too large, the underpinning procedure is delayed, and the serious person causes the interruption or failure of the wall reconstruction.
Meanwhile, different house reconstruction requires underpinning devices with different heights, the assembly or adjustment of some devices is very complex, and the assembly and adjustment of the devices before construction consume a large amount of time, so that the construction efficiency is influenced.
