Embodiment
With reference to specific implementation case, the present invention is expanded on further.It should be understood that reading the content of the invention lectured
Afterwards, those skilled in the art can make various changes or modifications to the present invention, and these equivalent form of values equally fall within the application institute
Attached claims limited range.
As shown in figure 1, the present invention utilizes basement frame in the construction area including basement and basement upper floor
Trestle or superstructure frame column 11 are as column 1, and construct inverse conversion beam 2 and inverse conversion beam region Nei Lou on column 1
Layer beam 3, makes column 1 support inverse conversion beam 2 and floor beam 3, utilizes inverse the facing as superstructure shear wall 5 of conversion beam 2
When supporting member, to superstructure and underground structure synchronous construction.
The present invention eliminates the initial internal force for needing to retain beam section [floor beam 3] in inverse conversion beam by the rearmounted carrier band 4 that unloads, real
Existing inverse conversion beam 2 unites two into one with floor beam 3.Its section of floor beam 3 in the inverse region of conversion beam 2 is less than inverse conversion beam
2, floor beam 3 is wrapped in inverse conversion beam 2 when both merge construction.It is inverse to complete and treat bottom not influence normally to use
Shear wall construction needs the concrete that will be wrapped in around floor beam 3 afterwards in place（Inverse conversion beam）Cut.Because the inverse stage should
Two-in-one beam bears top shear wall as the conversion beam of top shear wall and transmits load, therefore, it is inverse after the completion of in the beam
In the presence of a larger initial internal force, the internal force is more than internal force of the floor beam 3 in serviceability limit stage.To ensure structure safety,
Need to unload inverse conversion beam 2 and floor beam 3 before cutting, to eliminate initial internal force in beam.The unloading manner that this case is recommended
System is wrapped in around floor beam 3 cutting by eliminating initial internal force in beam in the rearmounted carrier band 4 that unloads of floor beam 3 span centre, i.e.,
Before concrete, a wide post-cast strip of 300mm is first dug out as rearmounted in the span centre of floor beam 3 and unloads carrier band unloading, is then dug again
It is re-closed after the completion of work to be cut to unload carrier band except the concrete around the section of floor beam 3.
As shown in Fig. 2 it is described constructed on column 1 inverse conversion beam 2 and floor beam 3 when by the reinforcing bar of floor beam 3（A）Press
Design requirement is configured in inverse conversion beam 2, and with the reinforcing bar of floor beam 3（A1）Instead of the part reinforcing bar of inverse conversion beam 2.
The column 1 is steel core concrete column in the inverse stage, it is inverse after the completion of in the periphery of column 1 parcel armored concrete
Form profile steel concrete column.
Less than one layer of shear wall 6 treats basement after the completion of inverse using the construction of the positive practice.
Embodiment 1
Certain engineering superstructure uses frame-shear-wall structure system, if three layers of basement, basement construction area about 11
Ten thousand m2, to meet superstructure construction period, reverse construction need to be used.To realize inverse demand, design is proposed such as Fig. 3-8 institutes
The inverse scheme shown is as follows：
1. as shown in figure 3, basis uses cast-in-situ bored pile 7, by the use of basement frame column or superstructure frame column as
Column 1, column 1 uses steel core concrete column in the inverse stage, and cast-in-situ bored pile 7 inserts column 1 in stake 7 when constructing.
2. set inverse phase transition beam 2 in shearing wall zone and constitute frame structure with column 1；Inverse conversion beam is located at one
Layer.
3. by the reinforcing bar of the floor beam 3 in region during the inverse conversion beam 2 of construction（A）By design requirement configuration in inverse conversion
In beam 2, and with the reinforcing bar of floor beam 3（A1）Instead of the inverse part reinforcing bar of conversion beam 2, specific detail drawing 2.
4. it is as shown in Figure 4 and Figure 5, rest to superstructure with inverse conversion beam 2 and column 1（Cut including superstructure
Power wall 5, frame column 11, beam 10, top floorboard）And basement structure（Including basement floor beam 9, basement floorboard and
Cushion cap 8）Synchronous construction；Less than one layer of shear wall 6 treats basement after the completion of inverse using the construction of the positive practice.
5. its section of floor beam 3 and internal force in the inverse region of conversion beam 2 are respectively less than inverse conversion beam 2, both apply in merging
Man-hour floor beam 3 is wrapped in inverse conversion beam 2.It is inverse to complete and treat that the construction of bottom shear wall 6 is arrived not influence normally to use
The concrete chisel removal that will be wrapped in around floor beam 3 is needed behind position（As shown in Figure 7）.Because the two-in-one beam of inverse stage is as upper
The conversion beam of portion's shear wall 5 bears the load that top shear wall 5 is transmitted, therefore, it is inverse after the completion of exist in the beam one compared with
Big initial internal force, the internal force is more than internal force of the floor beam 3 in serviceability limit stage.To ensure structure safety, needed before cutting pair
Inverse conversion beam 2 and floor beam 3 are unloaded（As shown in Figure 6）, to eliminate initial internal force in beam.This case unloading manner system passes through
Bring initial internal force in elimination beam in rearmounted unload of the span centre of floor beam 3, i.e., cut the concrete that is wrapped in around floor beam 3 it
Before, first dig out a wide post-cast strip of 300mm in the span centre of floor beam 3 and unloaded as the rearmounted carrier band 4 that unloads, floor beam is then cut again
Concrete around 3 sections, it is re-closed after the completion of work to be cut to unload carrier band 4（As shown in Figure 8）.
