Description

Three-dimensional framework of X-shaped tower column and construction method
Technical Field
The invention belongs to the technical field of bridge construction, and particularly relates to a three-dimensional framework of an X-shaped tower column and a construction method.
Background
The conventional cable-stayed bridge tower column is mainly formed by superposing visual geometric figures, and is more square in appearance. The tower column is easy to analyze and control the stress of the main bridge, is more convenient to construct and can well control the cost.
However, in order to highlight the feature of regional culture, a regional landmark building is created. At present, the tower columns of most cable-stayed bridges adopt special-shaped tower columns, the internal stress distribution of the special-shaped tower column structure is complex, and the stress on a main bridge is inconvenient to analyze and control, so that the special-shaped tower column structure is easy to be unstable, especially an X-shaped tower column. In order to ensure the construction quality of the X-shaped tower column, the three-dimensional framework of the tower column is often subjected to complex structural design; however, this approach increases the construction period and the construction cost.
The X-shaped tower column has changeable outlines and section styles, and the stress distribution state in the structure is relatively complex; in addition, the construction is faced with X-shaped cross construction. And the construction quality of the X-shaped tower column is difficult to ensure by using the traditional construction method.

In order to achieve the above purpose, the invention provides the following technical scheme:
a three-dimensional framework of an X-shaped tower column comprises two stiff frameworks which are arranged in an X-shaped crossed manner, wherein the stiff frameworks are sequentially divided into a lower separation section, a lower crossed closing section, a crossed section, an upper crossed closing section and an upper separation section from the lower end of the stiff frameworks to the upper part,
the cross-sectional shape of the lower separation section and the cross-sectional shape of the upper separation section are both of a single-opening type;
the cross section shapes of the lower cross closing sections and the upper cross closing sections are both double-opening shapes;
the cross-sectional shape in the cross-section is "sun" shaped.
The three-dimensional framework of the X-shaped tower column comprises two stiff frameworks, and the two stiff frameworks are arranged in a crossed manner according to the shape of the X-shaped tower column, namely the two stiff frameworks are mutually independent from the wall toe of the tower column upwards, and the distance between the two stiff frameworks is gradually reduced along with the increase of the height; after a certain height is reached, the two stiff frameworks are mutually crossed (combined into one), after the certain height is reached, the two stiff frameworks are gradually separated, and the distance between the two stiff frameworks is gradually increased along with the increase of the height, so that the X-shaped crossing of the two stiff frameworks is completed.
In the three-dimensional framework of the X-shaped tower column provided by the invention, the single-opening type refers to that: the two stiff frameworks are separated, and in each stiff framework, the cross section of each stiff framework is in a shape of a Chinese character kou. The cross sections of the lower separation section and the upper separation section are in a single-opening shape, so that concrete can be poured in the stiff framework, and the stress performance of the lower separation section and the upper separation section can be improved.
The "double-port" type means: the spacing distance between the two stiff frameworks is smaller, and in each stiff framework, the cross section of each stiff framework is in a shape of a Chinese character 'kou'; and because the distance between the two stiff frameworks is smaller, the two stiff frameworks are closer to each other on the cross section, and then two square shapes with smaller interval distance can appear. The cross section shapes of the upper cross closing section and the lower cross closing section are both in a double-opening shape, so that concrete can be poured in the stiff framework, and the stress performance of the upper cross closing section and the lower cross closing section can be improved.
The "daily" type means: the two stiff frameworks are combined into one, and in the combined stiff frameworks, the cross section of the combined stiff frameworks is in a shape of Chinese character ri. The cross section of the cross section is in a shape of a 'ri', namely two stiff frameworks are combined into one for construction at the cross section, so that concrete is favorably poured in the stiff frameworks, and the stress performance of the cross section is favorably improved.
In the three-dimensional framework of the X-shaped tower column, the stability of the internal structure of the X-shaped tower column is ensured by using the mode that two stiff frameworks are arranged in a crossed manner according to the shape of the X-shaped tower column, the structure is simple and reliable, and the construction is convenient, so that the construction period can be effectively shortened, and the construction cost can be reduced.
Furthermore, reinforcing steel bar groups are uniformly distributed on the periphery of each stiff skeleton, and in the height direction, the reinforcing steel bar groups are matched with the shapes of the corresponding stiff skeletons. Through the structure, the rigidity of the stiff frameworks is increased conveniently, and the stiff frameworks are fixed conveniently.

and finishing a hydraulic creeping formwork system at the lower end of the crossed section, and finishing the construction of the crossed section, the construction of the upper crossed closing section and the construction of the upper separation section by utilizing the hydraulic creeping formwork system.
In the construction method of the three-dimensional framework of the X-shaped tower column, the construction cutting point of a hydraulic creeping formwork system is arranged in a lower separation section by carrying out sectioning construction on the three-dimensional framework of the X-shaped tower column; the lower separation section is lower in height, so that the hydraulic creeping formwork system can be driven to be installed through conventional construction; in the process of constructing the three-dimensional framework of the X-shaped tower column, a hydraulic creeping formwork system is perfected at the same time, so that the construction period can be effectively shortened; and after the three-dimensional framework of the X-shaped tower column is constructed to a certain height, a hydraulic creeping formwork system can be utilized to carry out subsequent construction on the three-dimensional framework sections of the X-shaped tower column.

Further, before the construction of the lower crossed close sections, a truss platform is installed on the finished lower separation sections;
and in the process of constructing the lower crossed close sections, simultaneously erecting the lower frame layer hydraulic climbing formwork truss on the truss platform.
Furthermore, the cross sections are divided into at least a cross section and a cross section from bottom to top, and in the process of constructing the cross section, an upper-layer hydraulic climbing formwork truss is erected on the lower-layer hydraulic climbing formwork truss to complete the hydraulic climbing formwork system. In the process of constructing the three-dimensional framework of the X-shaped tower column, a hydraulic creeping formwork system is perfected at the same time, so that the construction period can be effectively shortened.
Further, the hydraulic creeping formwork system is converted in the crossing section.
In the construction method of the three-dimensional framework of the X-shaped tower column provided by the invention, the step of converting the hydraulic creeping formwork system in the crossed sections is as follows: the hydraulic climbing formwork system is arranged in the cross section, and guide rails in the hydraulic climbing formwork system need to be readjusted and installed.

Detailed Description
The present invention will be described in further detail with reference to test examples and specific embodiments. It should be understood that the scope of the above-described subject matter is not limited to the following examples, and any techniques implemented based on the disclosure of the present invention are within the scope of the present invention.
Example 1
This example 1 provides a three-dimensional framework of an "X" type tower column.
As shown in fig. 1, the present embodiment 1 includes two stiff frameworks 100, and the two stiff frameworks 100 are arranged in an X-shape in a crossing manner. And in each stiff skeleton 100, each stiff skeleton 100 is sequentially divided into a lower separation section 101, a lower crossing closing section 102, a crossing section 103, an upper crossing closing section 104 and an upper separation section 105 from bottom to top. Specifically, as shown in fig. 1, the overall stiff skeleton 100 is divided into thirteen small segments, wherein the lower split segment 101 includes a first segment and a second segment, the lower cross closing segment 102 is a third segment, the cross segments 103 include a fourth segment, a fifth segment, a sixth segment, a seventh segment, an eighth segment, a ninth segment, a tenth segment and an eleventh segment, the upper cross closing segment 104 includes a twelfth segment, and the upper split segment 105 is a thirteenth segment.
In the present embodiment 1, as shown in fig. 2 and 3, the cross-sectional shape of the lower separation section 101 is a "single-port" type; as shown in FIG. 16, the cross-sectional shape of the upper separator segment 105 is also "single-ported". In this embodiment 1, the "single-die type" means: the two stiff frameworks 100 are separated, and in each stiff framework 100, the cross-sectional shape of each stiff framework 100 is square.
In this embodiment 1, as shown in fig. 4 and 5, the cross-sectional shape of the lower cross closing segment 102 is a "double-mouth" type; as shown in fig. 15, the cross-sectional shape of the upper interdigitated segment 104 is also "double-ported". In this example 1, the "double-port" type means: the spacing distance between the two stiff frameworks 100 is small, and in each stiff framework 100, the cross section of each stiff framework 100 is square; since the distance between the two stiff frameworks 100 is small, the two stiff frameworks 100 are close to each other on the cross section, and then two square shapes with small distance can be formed.
In the present embodiment 1, as shown in fig. 6 to 14, the cross-sectional shape in the intersecting segment 103 is a "sun" shape. In this example 1, the "day" type means: the two stiff frameworks 100 are combined into one, and in the combined stiff frameworks 100, the cross section of the combined stiff framework 100 is shaped like a Chinese character ri.
In this embodiment 1, the two stiff frameworks 100 are arranged in a crossed manner according to the shape of the "X" tower column, that is, the two stiff frameworks 100 are independent from each other from the wall and toe of the tower column to the upper side, and the distance between the two stiff frameworks 100 is gradually reduced with the increase of the height; after a certain height is reached, the two stiff frameworks 100 are mutually crossed (combined into one), after the certain height is reached, the two stiff frameworks 100 are gradually separated, and the distance between the two stiff frameworks 100 is gradually increased along with the increase of the height, so that the X-shaped crossing of the two stiff frameworks 100 is completed.
In this embodiment 1, the stability of the internal structure of the "X" type tower column is ensured by using a mode that two stiff frameworks 100 are arranged in a crossed manner according to the shape of the "X" type tower column, and the structure is simple and reliable, so that the construction is facilitated, the construction period can be effectively shortened, and the construction cost can be reduced.
Further, in order to increase the rigidity of the stiff frameworks 100 and facilitate the fixation between the stiff frameworks 100, in this embodiment 1, the steel bar groups 106 are uniformly distributed around each stiff framework 100, and in the height direction, the steel bar groups 106 are adapted to the shape of the corresponding stiff frameworks 100. In the crossing section 103, the reinforcing bars in the two reinforcing bar groups 106 are fixed to each other so as to ensure the relative position between each stiff frame 100.
Example 2
The embodiment 2 provides a construction method of a three-dimensional framework of an "X" type tower column, and the embodiment 2 is used for constructing the three-dimensional framework of the "X" type tower column in the embodiment 1.
Before the construction of this example 2, the three-dimensional framework of the "X" type tower column in example 1 is segmented. In each stiff skeleton 100, each stiff skeleton 100 is divided into a lower separation section 101, a lower crossing approaching section 102, a crossing section 103, an upper crossing approaching section 104, and an upper separation section 105 in sequence from bottom to top. Specifically, as shown in fig. 1, the overall stiff skeleton 100 is divided into thirteen small segments, wherein the lower split segment 101 includes a first segment and a second segment, the lower cross closing segment 102 is a third segment, the cross segments 103 include a fourth segment, a fifth segment, a sixth segment, a seventh segment, an eighth segment, a ninth segment, a tenth segment and an eleventh segment, the upper cross closing segment 104 includes a twelfth segment, and the upper split segment 105 is a thirteenth segment.
In the embodiment 2, the three-dimensional framework of the X-shaped tower column in the embodiment 1 is constructed from bottom to top;
s1, constructing the lower separation segment 101, namely the first segment and the second segment in fig. 1, embedding creeping cones when implementing the first segment and the second segment, and installing a hydraulic creeping formwork fixing frame in the lower separation segment 101.
Furthermore, in order to facilitate the uniform construction height of the leveling tower column and facilitate the quality of subsequent construction, when the first section and the second section are constructed, the tops of the two sections of tower columns should be ensured to be flush, that is, the tops of the first section and the second section are ensured to be equal in height.
And S2, constructing the lower cross close sections 102, namely constructing a third section, and completing the erection of the hydraulic creeping formwork truss of the lower frame layer in the third section. Specifically, before constructing the third section, a truss platform is installed on the second section; and in the process of constructing the third section, simultaneously, a lower-layer hydraulic climbing formwork truss is erected on the truss platform.
S3, constructing the crossing segment 103, i.e., constructing the fourth segment to the eleventh segment. When the cross sections 103 are constructed, the cross sections 103 are at least divided into a cross section and a cross section from bottom to top, and in the process of constructing the cross section, an upper-layer hydraulic climbing formwork truss is simultaneously erected on a lower-layer hydraulic climbing formwork truss to complete a hydraulic climbing formwork system. Specifically, the crossing segment 103 may be divided into a crossing segment, and a crossing segment, wherein the crossing segment is a fourth segment, the crossing segment includes fifth to eighth segments, the crossing segment includes ninth to eleventh segments, and the crossing segment is a middle portion of the crossing segment 103. Meanwhile, when the fourth section is constructed, an upper-frame-layer hydraulic climbing formwork truss is erected on the lower-frame-layer hydraulic climbing formwork truss to complete a hydraulic climbing formwork system; and then completing the two-section crossing by utilizing a hydraulic climbing formwork system.
Because the construction height of the hydraulic creeping formwork system can be freely regulated and controlled between 3.8m and 6.3m, when the construction height is higher, the hydraulic creeping formwork system needs to be converted, namely the guide rail of the hydraulic creeping formwork system needs to be regulated and installed again; and then, the converted hydraulic climbing formwork system is used for finishing three sections of crossing.
In this embodiment 2, the crossing segment 103 is set as a switching position of the hydraulic climbing formwork system, specifically, the top of the crossing segment, that is, the eighth segment is set as a switching position of the hydraulic climbing formwork system. Because the construction difficulty of the cross section 103 is higher, the construction position is longer, and the construction height is higher, the top of the cross two sections, namely the eighth section, is set as the conversion position of the hydraulic creeping formwork system, which is beneficial to improving the safety of the construction cross three sections and the construction cross parts above the three sections.
And S4, completing the construction of the upper crossing close section 104 and the upper separation section 105 by using a hydraulic climbing formwork system.
When the stiff frameworks 100 are constructed in this embodiment 2, reinforcing bars are arranged around each stiff framework 100 to form a reinforcing bar group 106. Thereby contributing to an increase in the structural strength of the stiff skeleton 100 and to fixing the position of the stiff skeleton 100. Preferably, in the construction crossing section 103, the reinforcing bars in the two reinforcing bar groups 106 are fixed to cross in order to secure a relative position between each stiff frame 100.
In this embodiment 2, a construction cut-in point of a hydraulic climbing formwork system is set in the lower separation segment 101 by performing sectioning construction on an X-shaped tower column three-dimensional framework; the lower separation section 101 is low in height, so that the hydraulic creeping formwork system can be driven to be installed through conventional construction; in the process of constructing the three-dimensional framework of the X-shaped tower column, a hydraulic creeping formwork system is perfected at the same time, so that the construction period can be effectively shortened; and after the three-dimensional framework of the X-shaped tower column is constructed to a certain height, a hydraulic creeping formwork system can be utilized to carry out subsequent construction on the three-dimensional framework sections of the X-shaped tower column.
In the embodiment 2, the hydraulic creeping formwork system is used for constructing the three-dimensional framework of the X-shaped tower column, so that the labor intensity of construction can be effectively reduced, and construction risk points can be effectively reduced; in addition, the construction period and the construction quality are well controlled.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
