Detailed description of the invention
Below in conjunction with concrete case study on implementation, set forth the present invention further.Should be understood that those skilled in the art can make various changes or modifications the present invention, and these equivalent form of values fall within the application's appended claims limited range equally after the content of having read the present invention's instruction.
As shown in Figure 1, the present invention is in the construction area comprising basement and basement upper floor, utilize basement frame column or superstructure frame column 11 as column 1, column 1 to be constructed floor beam 3 in inverse conversion beam 2 and inverse conversion beam region, column 1 is made to support inverse conversion beam 2 and floor beam 3, utilize inverse conversion beam 2 as the temporary support component of superstructure shear wall 5, to superstructure and underground structure synchronous construction.
The present invention eliminates in inverse conversion beam by the rearmounted carrier band 4 that unloads the initial internal force needing to retain beam section [floor beam 3], realizes inverse conversion beam 2 and unites two into one with floor beam 3.Its cross section of floor beam 3 in inverse conversion beam 2 region is less than inverse conversion beam 2, and when both merge construction, floor beam 3 is wrapped in inverse conversion beam 2.For not affecting normal use, inversely completing and after bottom shear wall construction puts in place, needing the concrete be wrapped in around floor beam 3 (inverse conversion beam) to cut.Transmit load because this two-in-one beam of inverse stage bears top shear wall as the conversion beam of top shear wall, therefore, inverse complete after there is a larger initial internal force in this beam, this internal force is greater than the internal force of floor beam 3 at serviceability limit stage.For guaranteeing structural safety, need before cutting to unload inverse conversion beam 2 and floor beam 3, to eliminate initial internal force in beam.The unloading manner system that this case is recommended is by eliminating initial internal force in beam at the rearmounted carrier band 4 that unloads of floor beam 3 span centre, namely before cutting the concrete be wrapped in around floor beam 3, first dig out the wide ater-casting of 300mm at floor beam 3 span centre and unload carrier band unloading as rearmounted, and then the concrete cut around floor beam 3 cross section, close again after the work of cutting completes and unload carrier band.
As shown in Figure 2, described construct on column 1 inverse conversion beam 2 and floor beam 3 time the reinforcing bar (A) of floor beam 3 is configured in inverse conversion beam 2 by designing requirement, and replace the part reinforcing bar of inverse conversion beam 2 with the reinforcing bar of floor beam 3 (A1).
Described column 1 is steel core concrete column in the inverse stage, inverse complete after column 1 periphery parcel steel concrete formed profile steel concrete column.
Shear wall 6 below one deck until basement is inverse complete after adopt the positive practice to construct.
Embodiment 1
Certain engineering superstructure adopts frame-shear-wall structure system, if three layers of basement, and basement building area about 110,000 m
2, for meeting superstructure construction period, need reverse construction be adopted.For realizing inverse demand, the inverse scheme that design proposes as shown in figures 3-8 is as follows:
1. as shown in Figure 3, basis adopts bored pile 7, utilizes basement frame column or superstructure frame column as column 1, and column 1 adopts steel core concrete column in the inverse stage, is inserted in stake 7 by column 1 when bored pile 7 is constructed.
2. establish inverse phase transition beam 2 in shear wall region and form frame construction with column 1; Inverse conversion beam is located at one deck.
3. during construction inverse conversion beam 2, the reinforcing bar (A) of the floor beam 3 in region is configured in inverse conversion beam 2 by designing requirement, and replaces inverse conversion beam 2 part reinforcing bar with the reinforcing bar of floor beam 3 (A1), concrete detail drawing 2.
4. as shown in Figure 4 and Figure 5, with inverse conversion beam 2 and column 1 for rest is to superstructure (comprising superstructure shear wall 5, frame column 11, beam 10, top floor plate) and basement structure (comprising basement floor beam 9, basement floor plate and cushion cap 8) synchronous construction; Shear wall 6 below one deck until basement is inverse complete after adopt the positive practice to construct.
5. its cross section of floor beam 3 in inverse conversion beam 2 region and internal force are all less than inverse conversion beam 2, and when both merge construction, floor beam 3 is wrapped in inverse conversion beam 2.For not affecting normal use, inversely completing and need the concrete chisel removal (as shown in Figure 7) that will be wrapped in around floor beam 3 after bottom shear wall 6 construction puts in place.Because this two-in-one beam of inverse stage bears as the conversion beam of top shear wall 5 load that top shear wall 5 transmits, therefore, inverse complete after there is a larger initial internal force in this beam, this internal force is greater than the internal force of floor beam 3 at serviceability limit stage.For guaranteeing structural safety, need before cutting to unload (as shown in Figure 6) inverse conversion beam 2 and floor beam 3, to eliminate initial internal force in beam.This case unloading manner system is by bringing initial internal force in elimination beam rearmounted the unloading of floor beam 3 span centre, namely before cutting the concrete be wrapped in around floor beam 3, the ater-casting of first digging out 300mm wide at floor beam 3 span centre unloads as the rearmounted carrier band 4 that unloads, and then the concrete cut around floor beam 3 cross section, close again after the work of cutting completes and unload carrier band 4(as shown in Figure 8).
