According to the traditional construction method, the construction of the upper structure can only be carried out after the reinforcement of the lower structure is completed. Since the reinforcement of the lower structure takes a long time, it will take a long time to construct the new upper structure after the reinforcement work is completed.

Embodiment Construction
[0018] The present invention will be further described in conjunction with the accompanying drawings.
[0019] Figure 4 It is the layout plan of the conversion beam for the measure, which shows that the lower shear wall cannot be constructed due to the unfinished reinforcement, and the upper structural shear wall can transfer the load of the upper shear wall to the column through the beam of this measure.
[0020] Such as figure 1 , figure 2 , image 3 Shown, specific embodiment of the present invention carries out according to the following steps:
[0021] (1) First remove part of the beams and slabs of the original structure 1 to make it suitable for upward construction, conduct a comprehensive inspection of the wall columns 3 and beams and slabs 4 of the original structure 1, and evaluate the status of the structure itself, according to the original structure design drawings Determine the mechanical performance of the wall column 3 of the original structure based on t...

The invention relates to a method for simultaneous construction of an additionally built superstructure and reinforcement of an original understructure. The original understructure requires reinforcement, and the superstructure is additionally built. Measure transfer beams are disposed to complete downward transfer of load of the additionally built superstructure under the condition that stress of the original bearing understructure is allowable, and accordingly simultaneous construction of the superstructure and the understructure is achieved. Upper load is applied to the measure transfer beams and is transferred through a vertical structure, so that simultaneous construction of the original understructure reinforcement and the additionally built superstructure is realized, the time for awaiting the reinforcement of the original understructure before the construction of the superstructure is omitted, construction process is evidently increased, and construction period is shortened.
Description
technical field [0001] The invention relates to a method for simultaneously constructing the original structure of the lower part and the newly added structure of the upper part, belongs to the technical field of building structure construction, and is suitable for building structures in which the lower part is reinforced and the upper part is newly added. Background technique [0002] With the development of the urbanization process, a large number of high-rise buildings have sprung up everywhere. Due to various reasons, some high-rise buildings have not been completed after construction, and construction needs to continue after shelving for a period of time. In order to achieve the function of use, the follow-up construction should not be carried out according to the original drawings, or the original structure cannot meet the load requirements, so the substructure needs to be treated and the superstructure should be added at the same time. According to the traditional co...
