Detailed description of the invention
Below in conjunction with the accompanying drawings embodiment of the present invention one vertical member leveling method is described in detail.
The embodiment of the present invention provides a kind of vertical member leveling method, as it is shown in figure 1, include: step 1,
By hinged to horizontal member and vertical member；Step 2, carry out disposable gravity laod applying；Step 3, tune
The sectional dimension of whole vertical member, the vertical deformation making each vertical member is identical；Step 4, by horizontal structure
Part just connects with vertical member.
In the vertical member leveling method that the embodiment of the present invention provides, due to first by structure level component with perpendicular
Hinged to component, therefore during the leveling of vertical member, horizontal member is not involved in the change of vertical member
Shape is coordinated, and does not produce and may cause relatively owing to needing to coordinate vertical member deformation under gravity laod
Big internal force, during vertical member deformation leveling under gravity laod, stress is simple, it is not necessary to consider level
Internal force transfer between component and vertical member, and then without carrying out successive ignition tentative calculation leveling, it is only necessary to right
The disposable gravity laod applied carries out one-time leveling and calculates, and makes the vertical deformation leveling of vertical member
Simply, reliably.Treat that the vertical deformation of each vertical member is identical, will after each vertical member leveling, then
Horizontal member is just connect with vertical member, carries out follow-up antidetonation, wind resisting structure design.It addition, this
In the vertical member leveling method that inventive embodiments provides, horizontal member is hinged with vertical member, and
Structure gravity laod once applies, and therefore can eliminate structure later stage additional dead load and live loading institute
The relative settlement produced and additional internal force, it is to avoid the construction period is had a negative impact；Meanwhile, may be used
To avoid construction floor vertical deformation difference to continue to build up, fundamentally solve under gravity laod perpendicular
Problem to component pressuring stress level difference.
Wherein, in order to vertical member leveling method that the present invention provide is better described, with one group (two)
Illustrate as a example by vertical member, as in figure 2 it is shown, specifically may be used hinged for horizontal member 1 in step 1
Thinking, in skyscraper or high-rise building, (multiple) horizontal member 1 is positioned at adjacent (two)
Between vertical member 2, and the intersection of each horizontal member 1 and vertical member 2 is and is articulated and connected,
As shown in multiple circles between horizontal member 1 and vertical member 2 in Fig. 2, therefore, this is articulated and connected
Mode can be during the leveling of vertical member 2, the additional internal force of emission levels component 1, it is to avoid its
Deformation leveling on vertical member 2 produces impact, thus is conducive to flat for executive information systems regulation
Whole.
Wherein, the disposable gravity laod that carries out in step 2 applies to be specifically as follows, structural stiffness matrix
Once generating, gravity laod is disposably applied on different vertical members 2, as different vertical in Fig. 3
Shown in the arrow on component 2 top；And after this, adjust the sectional dimension of vertical member 2, make complete
The each floor in building each vertical member pressuring stress level is uniform, and vertical deformation is consistent.
Specifically, in the vertical member leveling method that the embodiment of the present invention provides, as shown in Figures 2 and 3,
Different types of vertical member 2 is specifically as follows exterior frame column 21 and inner core wall limb 22.It is of course also possible to be
Other vertical structure part in building.Wherein, the sectional dimension adjusting vertical member 2 in step 3,
The concrete steps making the vertical deformation of each vertical member 2 identical may include that step 31, calculate difference
The initial vertical deformation Δ of the vertical member 2 of type；Step 32, adjust different types of vertical member 2
Sectional dimension, the vertical deformation making each vertical member 2 is identical.
In the embodiment of the present invention, as it is shown on figure 3, the initial vertical of the exterior frame column 21 in vertical member 2 becomes
Shape amount is Δ 1, and the initial vertical deformation of the inner core wall limb 22 in vertical member 2 is Δ 2.Due to housing
Post 21 and inner core wall limb 22 belong to different types of vertical member 2, therefore in own material, specification and be subject to
Under the different factor such as power situation, its initial vertical deformation Δ is caused to there are differences, i.e. at the beginning of exterior frame column 21
Beginning vertical deformation Δ 1 is different from the initial vertical deformation Δ 2 of inner core wall limb 22, the most in figure 3,
Above-mentioned Δ 1 > Δ 2.In order to make the different types of vertical member 2 compressive stress water in executive information systems
The evenest, vertical deformation is consistent, i.e. each vertical member 2 in leveling building.
Shown in Fig. 5, step 32, adjust the sectional dimension of different types of vertical member 2, make each
The vertical deformation of vertical member 2 is final vertical deformation Δ '.Such as when Δ '=1/2* (Δ 1+ Δ 2),
Then adjust exterior frame column 21 so that it is initial vertical deformation is that Δ 1 diminishes, and equal to final vertical deformation Δ '；
Adjust inner core wall limb 22 so that it is initial vertical deformation is that Δ 2 becomes big, and equal to final vertical deformation Δ '；
The most now as it is shown in figure 5, the vertical deformation of each vertical member 2 in Jian Zhu is consistent.Certainly, in reality
In application, the final vertical deformation Δ ' of each vertical member 2 can be the arbitrary value in the range of Δ 1 to Δ 2.
Further, step 32 adjusts the cross section of different types of vertical member 2 be specifically as follows and pass through
Change the sectional dimension of different vertical member 2, and the material etc. of vertical member 2 adjusts different vertical
The vertical deformation of component 2, the pressuring stress level making each vertical member of each layer 2 of whole building is uniform,
The vertical deformation of the most each vertical member 2 is consistent, thus the structure peace of beneficially executive information systems
Congruence.
In the vertical member leveling method that the embodiment of the present invention provides, and Super High knot high-rise for major part
Structure is built, under not considering the horizontal force action that earthquake or wind load cause, only in gravity laod generation
Under tabular value effect, the axial compression ratio of above-mentioned different types of vertical member 2 can be 0.5, i.e. exterior frame column
21 and the axial compression ratio of inner core wall limb 22 desirable unanimously, thus in different types of vertical member 2
Exterior frame column 21 and inner core wall limb 22 can be by changing its cross section and material etc. so that it is vertically adjust
Put down and keep consistent.
During actual application, as Fig. 5 combines shown in Fig. 6, by horizontal member 1 and vertical member 2 in step 4
Just connect, to carry out follow-up structural seismic, wind force proofing design.
The above, the only detailed description of the invention of the present invention, but protection scope of the present invention is not limited to
In this, any those familiar with the art, can be easily in the technical scope that the invention discloses
Expect change or replace, all should contain within protection scope of the present invention.Therefore, the protection of the present invention
Scope should described be as the criterion with scope of the claims.
