Description

Technical Field

[0001] This application relates to the field of subway engineering, and more specifically, to a modular assembly structure for panel partition walls in subway stations. Background Technology

[0002] In recent years, with the modernization of the construction industry, the country has vigorously promoted prefabricated buildings and green construction methods. The rail transit construction industry has also gradually explored the application of prefabricated lightweight partition walls. However, the research is currently limited to flat-roof, straight-wall stations, as these are suitable for modular assembly of prefabricated panel partition walls. For some subway stations, such as those constructed using the cut-and-cover method, the main roof slab is curved. The prefabricated lightweight partition walls currently being researched are not suitable for curved roof slabs.

[0003] Therefore, how to make prefabricated lightweight partition walls suitable for curved ceilings has become a technical problem that needs to be solved in this field. Utility Model Content

[0004] In view of this, this application proposes a modular assembly structure for panel partition walls in subway stations, so as to make panel partition walls applicable to curved ceilings.

[0005] According to this application, a modular assembly structure for panel partition walls in subway stations is proposed. This modular assembly structure includes: a panel partition wall, comprising a first sub-panel partition wall assembled from standard modular panels; a partition wall support system, comprising steel columns, a first steel beam, a first steel channel, and a second steel channel. The steel columns are supporting columns, positioned adjacent to the structural sidewalls or steel pipe columns. The first steel beam is the partition wall's central beam, horizontally positioned at a distance exceeding a preset ground level, with both ends connected to the steel columns. The first steel channel is the partition wall's top beam, connecting the first sub-panel partition wall and the structural top slab. The second steel channel is the partition wall's bottom beam, connecting the first sub-panel partition wall and the structural bottom slab. The structural top slab is an arc-shaped top slab. When the panel partition wall is parallel to the structural top slab, the first steel channel is a horizontal steel channel; when the panel partition wall is perpendicular to the structural top slab, the first steel channel is an arc-shaped steel channel.

[0006] Optionally, the plate partition wall further includes a second sub-plate partition wall, which includes a lower irregular-shaped standard modular plate and a middle irregular-shaped standard modular plate. The partition wall support system also includes a second steel beam, which includes a lower flange steel beam, an upper flange steel beam, and a lower column cap steel beam. The lower flange steel beam is located on the side of the flange closest to the structural base plate, the upper flange steel beam is located on the side of the flange furthest from the structural base plate, and the lower column cap steel beam is located on the side of the column cap closest to the structural base plate. The lower irregular-shaped standard modular plate is located between the second steel channel and the lower flange steel beam, and the middle irregular-shaped standard modular plate is located between the upper flange steel beam and the lower column cap steel beam. The modular assembly structure of the plate partition wall also includes a column cap caulking and sealing structure and a flange caulking and sealing structure. The column cap caulking and sealing structure fills the gap between the structural top plate and the lower column cap steel beam, and the flange caulking and sealing structure fills the gap between the lower flange steel beam and the upper flange steel beam.

[0007] Optionally, when the plate partition wall intersects with the steel pipe column, the steel column is provided on both sides of the steel pipe column, and the two ends of the steel beam under the flange, the two ends of the steel beam on the flange, and the two ends of the steel beam under the column cap are respectively welded to the steel column and the steel pipe column.

[0008] Optionally, when the plate partition wall is tangent to the steel pipe column, the steel columns are provided on both sides of the steel pipe column, and the two ends of the steel beam under the flange, the two ends of the steel beam on the flange, and the two ends of the steel beam under the column cap are all welded to the steel column.

[0009] Optionally, both the column cap caulking and sealing structure and the flange caulking and sealing structure are made of plain concrete.

[0010] Optionally, when the plate partition wall is parallel to the structural top plate, the modular assembly structure of the plate partition wall further includes a top plate caulking and sealing structure, which is used to seal the space between the first steel channel and the structural top plate.

[0011] Optionally, the first sub-panel partition wall includes a lower standard modular panel, a middle standard modular panel, and an upper standard modular panel.

[0012] Optionally, the partition wall support system includes two first steel beams, which are located between the lower standard modular plate and the middle standard modular plate, and between the middle standard modular plate and the upper standard modular plate, respectively.

[0013] Optionally, the first sub-panel partition wall is assembled from standard modular panels using an interlocking method.

[0014] According to the technical solution of this application, the structural top plate is an arc-shaped top plate, and a first steel channel is provided. When the plate partition wall is parallel to the structural top plate, the first steel channel is set as a horizontal steel channel. When the plate partition wall is perpendicular to the structural top plate, the first steel channel is set as an arc-shaped steel channel. In this way, the plate partition wall and the arc-shaped top plate can fit well, making the plate partition wall suitable for the arc-shaped top plate.

[0029] The technical solution of this application will now be described in detail with reference to the accompanying drawings and embodiments.

[0030] This application provides a modular assembly structure for panel partition walls in a subway station. The modular assembly structure includes panel partition walls 1 and a partition wall support system, such as... Figure 1 As shown. In this embodiment of the application, the board partition 1 can be a fireproof partition.

[0031] Panel partition wall 1 includes a first sub-panel partition wall. The first sub-panel partition wall is assembled from standard modular panels. The first sub-panel partition wall is located between the structural top slab 81 and the structural bottom slab 82. (See reference...) Figure 2 To understand.

[0032] Optionally, in this embodiment, the first sub-panel partition wall is assembled from standard modular panels using an interlocking method.

[0033] In this embodiment, the number of standard modular panels included in the first sub-panel partition wall can be determined according to specific circumstances. Optionally, in this embodiment, the first sub-panel partition wall includes a lower standard modular panel 71, a middle standard modular panel 72, and an upper standard modular panel 73, such as... Figure 2 As shown.

[0034] The partition wall support system includes steel columns 2, first steel beams 3, first steel channels 41 and second steel channels 42, such as Figure 2 As shown.

[0035] Steel column 2 serves as a supporting column. Steel column 2 can be positioned adjacent to either the structural side wall 83 or the steel pipe column 5. Specifically, when the plate partition wall 1 is located between the structural side wall 83 and the steel pipe column 5, two steel columns 2 are positioned on both sides of the first sub-plate partition wall, with each steel column 2 adjacent to both the structural side wall 83 and the steel pipe column 5. When the plate partition wall 1 is located between the steel pipe columns 5, two steel columns 2 are positioned on both sides of the first sub-plate partition wall, with each steel column 2 adjacent to the steel pipe column 5. When the plate partition wall 1 is located between the structural side walls 83, two steel columns 2 are positioned on both sides of the first sub-plate partition wall, with each steel column 2 adjacent to the structural side wall 83.

[0036] When steel column 2 is positioned adjacent to structural side wall 83, steel column 2 is directly connected to structural side wall 83. When steel column 2 is positioned adjacent to steel pipe column 5, there is a certain distance between steel column 2 and steel pipe column 5. Specifically, the size of the distance can be determined according to specific circumstances. For example, a flange 10 is installed in the middle of steel pipe column 5, and a column cap 9 is installed at the top of steel pipe column 5. The distance between steel column 2 and steel pipe column 5 can be determined according to the size of flange 10 and column cap 9, as long as it avoids flange 10 and column cap 9 and does not compress flange 10 and column cap 9.

[0037] Furthermore, in the embodiments of this application, when the first sub-plate partition wall is large, for example, when the width of the first sub-plate partition wall parallel to the ground is greater than or equal to 4m, steel columns 2 connecting the first steel channel 41 and the second steel channel 42 can be provided. The number of these columns can be determined according to specific circumstances to increase the stability of the entire partition wall support system. Figure 2 As shown in the diagram, a steel column 2 is provided to connect the first steel channel 41 and the second steel channel 42. The steel column 2 is also connected to the first steel beam 3.

[0038] The first steel beam 3 is the central beam of the partition wall. The first steel beam 3 is horizontally installed at a position exceeding a preset distance from the ground, and both ends of the first steel beam 3 are connected to the steel column 2. Figure 2 As shown.

[0039] The number of first steel beams 3 can be determined according to specific circumstances. In this embodiment, the structural roof slab 81 is an arc-shaped roof slab. Stations with arc-shaped roof slabs have higher floor heights (e.g., 6m-8m), and multiple first steel beams 3 can be set according to the specific floor height. The principle for setting the height is to minimize the number of standard modular panels. Using fewer standard modular panels can improve panel production efficiency and on-site construction and installation efficiency.

[0040] like Figure 2 or Figure 3 or Figure 4As shown, it includes two first steel beams 3. The two first steel beams 3 are located between the lower standard modular plate 71 and the middle standard modular plate 72, and between the middle standard modular plate 72 and the upper standard modular plate 73, respectively.

[0041] Optionally, in this embodiment of the application, the preset distance can be 2.5m.

[0042] Optionally, in this embodiment, the first steel beam 3 can be used as a fire door lintel.

[0043] The first steel channel 41 serves as the top beam of the partition wall. The first steel channel 41 connects the first sub-plate partition wall and the structural top plate 81. Specifically, the first steel channel 41 connects the first sub-plate partition wall and the structural top plate 81 near the bottom surface of the first sub-plate partition wall.

[0044] like Figure 2 As shown, the first sub-panel partition wall includes a lower standard modular panel 71, a middle standard modular panel 72, and an upper standard modular panel 73. The first steel channel 41 connects the upper standard modular panel 73 and the structural top plate 81.

[0045] The structural top slab 81 is an arc-shaped top slab. In this embodiment, the panel partition 1 can be perpendicular to the structural top slab 81; in other words, the panel partition 1 is parallel to the arc-shaped cross-section of the structural top slab 81. Figure 1 or Figure 2 As shown, the transverse partition wall 1A is perpendicular to the structural top slab 81. When the plate partition wall 1 is perpendicular to the structural top slab 81, the first steel channel 41 is an arc-shaped steel channel.

[0046] like Figure 2 As shown, the first sub-panel partition wall includes a lower standard modular panel 71, a middle standard modular panel 72, and an upper standard modular panel 73. When the structural top plate 81 is an arc-shaped top plate and the panel partition wall is perpendicular to the structural top plate 81, the surface where the upper standard modular panel 73 connects to the structural top plate 81 is an arc-shaped cross-section.

[0047] The structural top slab 81 is an arc-shaped top slab. In this embodiment, the plate partition wall 1 can be parallel to the structural top slab 81; in other words, the plate partition wall 1 is perpendicular to the arc-shaped section of the structural top slab 81. When the plate partition wall 1 is parallel to the structural top slab 81, the first steel channel 41 is a horizontal steel channel.

[0048] The second steel channel 42 serves as the bottom beam of the partition wall, connecting the first sub-panel partition wall and the structural base plate 82. Specifically, the second steel channel 42 connects the top surface of the first sub-panel partition wall and the structural base plate 82 near the first sub-panel partition wall. For example, as... Figure 2 As shown, the second steel channel 42 connects the lower standard modular plate 71 and the structural base plate 82.

[0049] Furthermore, the two ends of the second steel channel 42 are connected to steel columns 2, and the two ends of the steel columns 2 are connected to the first steel channel 41 and the second steel channel 42. In this embodiment, the second steel channel 42 may be a horizontal steel channel.

[0050] Optionally, in this embodiment of the application, when the panel partition wall 1 is parallel to the structural top plate 81, the modular assembly structure of the panel partition wall further includes a top plate caulking and sealing structure 13. For example... Figure 4 As shown, the top plate caulking and sealing structure 13 is used to seal the space between the first steel channel 41 and the structural top plate 81, so that the top surface of the first steel channel 41 near the structural top plate 81 is leveled. In other words, the top plate caulking and sealing structure 13 is used to seal the space between the top surface of the first steel channel 41 near the structural top plate 81 and the inner arc surface of the structural top plate 81 in the direction perpendicular to the ground.

[0051] Optionally, in this embodiment, the material used to prepare the roof slab caulking and sealing structure 13 can be concrete. Specifically, the roof slab caulking and sealing structure 13 can be a concrete strip.

[0052] The sealing performance of the assembled monolithic panel partition wall can be improved by setting the top plate caulking and sealing structure 13.

[0053] Optionally, in this embodiment, a flange 10 is provided in the middle of the steel pipe column 5, and a column cap 9 is provided at the top of the steel pipe column 5, such as... Figure 2 As shown.

[0054] Panel partition wall 1 also includes a second sub-panel partition wall. The second sub-panel partition wall includes a lower irregular-shaped standard modular panel 712 and a middle irregular-shaped standard modular panel 722, such as... Figure 2 As shown.

[0055] The partition wall support system also includes a second steel beam, which includes a lower flange steel beam 61, an upper flange steel beam 62, and a lower column cap steel beam 63.

[0056] The lower steel beam 61 of the flange 10 is located on the side of the flange 10 closest to the structural base plate 82, the upper steel beam 62 of the flange 10 is located on the side of the flange 10 furthest from the structural base plate 82, and the lower steel beam 63 of the column cap 9 is located on the side of the column cap 9 closest to the structural base plate 82. Figure 2 As shown.

[0057] The lower irregular-shaped standard modular plate 712 is located between the second steel channel 42 and the lower steel beam 61 of the flange, and the middle irregular-shaped standard modular plate 722 is located between the upper steel beam 62 of the flange and the lower steel beam 63 of the column cap, such as Figure 2 As shown, the lower flange steel beam 61, the upper flange steel beam 62, and the lower column cap steel beam 63 serve as the partition wall frame beams for the irregularly shaped standard modular panels. The irregularly shaped standard modular panels are installed and fixed using the lower flange steel beam 61, the upper flange steel beam 62, and the lower column cap steel beam 63.

[0058] The modular assembly structure of the panel partition wall also includes a column cap caulking and sealing structure 11 and a flange caulking and sealing structure 12, such as Figure 2 As shown. The column cap caulking and sealing structure 11 fills the gap between the top plate of the structure 81 and the lower steel beam 63 of the column cap, and the flange caulking and sealing structure 12 fills the gap between the lower steel beam 61 of the flange and the upper steel beam 62 of the flange.

[0059] A flange 10 is installed in the middle of the steel pipe column 5, and a column cap 9 is installed at the top of the steel pipe column 5. The column cap 9 is connected to the structural top plate 81. When the plate partition wall 1 intersects or is tangent to the steel pipe column 5, the steel column 2, which serves as the supporting column, avoids the flange 10 and the column cap 9. There is a gap between the steel pipe column 5 and the supporting column. The lower irregular standard modular plate 712 and the middle irregular standard modular plate 722 can fill the gap between the steel pipe column 5 and the supporting column, thereby improving the overall stability and sealing of the assembled plate partition wall. The structure of the steel pipe column 5, flange 10, and column cap 9 is uneven. The irregular standard modular plate is difficult to manufacture. The transportation of the irregular standard modular plate is difficult to protect the edges and corners of the plate, and the cost is high. It also requires high technical skills from the construction workers. The column cap caulking and sealing structure 11 and the flange caulking and sealing structure 12 can improve the integrity and sealing of the assembled plate partition wall and improve the prefabrication and assembly efficiency. Therefore, when steel pipe columns are used as the supporting structure in subway stations, the sealing of the connection point between the prefabricated modular partition wall and the steel pipe column 5 can be enhanced, the weak connection point can be alleviated, the integrity, sealing, stability and safety of the prefabricated modular partition wall can be improved, the fire resistance of the prefabricated modular partition wall can be improved, and safety hazards caused by the weak connection point can be avoided.

[0060] It should be noted that, Figure 2 The diagram shows the arrangement of the second sub-plate partition wall, the second steel beam, the column capital caulking and sealing structure, and the flange caulking and sealing structure when the plate partition wall 1 is perpendicular to the structural top slab 81. When the plate partition wall 1 is parallel to the structural top slab 81, the arrangement of the second sub-plate partition wall, the second steel beam, the column capital caulking and sealing structure, and the flange caulking and sealing structure is similar to that when the plate partition wall 1 is perpendicular to the structural top slab 81, and can be referred to accordingly. Figure 2 Let's try to understand it.

[0061] Optionally, in this embodiment, the column cap caulking and sealing structure 11 and the flange caulking and sealing structure 12 can be made of plain concrete. Alternatively, the column cap caulking and sealing structure 11 and the flange caulking and sealing structure 12 can also be made of other materials, as long as they can provide a sealing effect.

[0062] In this embodiment of the application, the positional relationship between the plate partition wall 1 and the steel pipe column 5 can be intersecting or tangent. For example... Figure 1As shown, the steel pipe column 5 is orthogonal to the first transverse partition wall 1A, and passes through the center of the steel pipe column 5 along the direction of the first transverse partition wall 1A; the positional relationship between the steel pipe column 5 and the second transverse partition wall 1B is tangent. It should be noted that the orthogonality between the steel pipe column 5 and the first transverse partition wall 1A is one type of intersection between the steel pipe column 5 and the first transverse partition wall 1A. This application uses the orthogonality between the steel pipe column 5 and the first transverse partition wall 1A as an example for illustrative purposes, but other intersection methods between the steel pipe column 5 and the first transverse partition wall 1A can be understood by referring to the relevant description of the orthogonality between the steel pipe column 5 and the first transverse partition wall 1A.

[0063] Optionally, in this embodiment, when the plate partition wall 1 intersects with the steel pipe column 5, steel columns are installed on both sides of the steel pipe column 5. The two ends of the steel beam 61 under the flange, the two ends of the steel beam 62 on the flange, and the two ends of the steel beam 63 under the column cap are welded to the steel column 2 and the steel pipe column 5, respectively. (Refer to...) Figure 2 or Figure 8 The first transverse partition wall 1A shown is understood to be orthogonal to the steel pipe column 5. In the embodiment of this application, when the plate partition wall 1 intersects with the steel pipe column 5, the column cap caulking and sealing structure 11 is provided at the position where the steel pipe column 5 and the plate partition wall 1 intersect at the column cap 9, and the flange caulking and sealing structure 12 is provided at the position where the steel pipe column 5 and the plate partition wall 1 intersect at the flange 10.

[0064] like Figure 2 or Figure 8 As shown, the first transverse partition wall 1A is orthogonal to the steel pipe column 5. Steel columns 2 are set on both sides of the steel pipe column 5 as supporting columns, and the steel columns 2 avoid the column cap 9 and flange 10. A column cap lower steel beam 63 is set at the lower end of the column cap 9 (on the side closest to the structural base plate 82). The two ends of the column cap lower steel beam 63 are welded to the square steel column 2 and the steel pipe column 5, respectively. The column cap section is filled with a column cap caulking and sealing structure 11. In other words, the gap in the space enclosed by the structural top plate 81, the column cap lower steel beam 63, the column cap 9, and the steel columns 2 serving as supporting columns is filled with the column cap caulking and sealing structure 11. Figure 6 Let's try to understand it.

[0065] Optionally, in this embodiment, the dimensions of the steel beam 63 under the column cap can be determined according to specific circumstances. For example, the width can be 100mm and the height can be 60mm.

[0066] like Figure 2 or Figure 8As shown, an upper steel beam 62 is installed at the upper end of flange 10 (the side away from the structural base plate 82), and a lower steel beam 61 is installed at the lower end of flange 10 (the side closer to the structural base plate 82). Both ends of the upper steel beam 62 and the lower steel beam 61 are welded to the steel column 2 and steel pipe column 5, which serve as supporting columns, respectively. The flange section is sealed using a flange caulking and sealing structure 12. In other words, the gaps in the space enclosed by the upper steel beam 62, the lower steel beam 61, the flange 10, and the supporting steel column 2 are filled using the flange caulking and sealing structure 12. (Refer to...) Figure 7 To understand this, we can use the following method. Optionally, in the embodiments of this application, the dimensions of the upper steel beam 62 and the lower steel beam 61 of the flange can be determined according to specific circumstances. For example, the width can be 100mm and the height can be 60mm.

[0067] In addition, refer to Figure 2 or Figure 5 As shown, a non-standard modular plate 722 is installed between the steel beam 63 under the column cap and the steel beam 62 on the flange; a non-standard modular plate 712 is installed between the steel beam 61 under the flange and the second channel steel 42.

[0068] Optionally, in this embodiment, when the plate partition wall 1 is tangent to the steel pipe column 5, steel columns 2 are installed on both sides of the steel pipe column 5. The two ends of the steel beam 61 below the flange, the two ends of the steel beam 62 above the flange, and the two ends of the steel beam 63 below the column cap are all welded to the steel columns 2. (Refer to...) Figure 2 or Figure 12 The second transverse partition wall 1B shown is understood to be tangent to the steel pipe column 5. In this embodiment, when the plate partition wall 1 is tangent to the steel pipe column 5, the column cap caulking and sealing structure 11 is provided at the position where the steel pipe column 5 and the plate partition wall 1 are tangent at the column cap 9, and the flange caulking and sealing structure 12 is provided at the position where the steel pipe column 5 and the plate partition wall 1 are tangent at the flange 10.

[0069] like Figure 2 or Figure 12 As shown, the second transverse partition wall 1B is tangent to the steel pipe column 5. Steel columns 2 are installed on both sides of the steel pipe column 5 as supporting columns, and the steel columns 2 avoid the column cap 9 and flange 10. A steel beam 63 is installed at the lower end of the column cap 9 (on the side closest to the structural base plate 82), and the two ends of the steel beam 63 are welded to the square steel column 2. The column cap section is filled with a column cap caulking and sealing structure 11. In other words, the gaps in the space enclosed by the steel columns 2, the steel beam 63, the structural top plate 81, and the column cap 9 on both sides of the steel pipe column 5 are filled with the column cap caulking and sealing structure 11. (Refer to...) Figure 10To understand this. Optionally, in the embodiments of this application, the dimensions of the steel beam 63 under the column cap can be determined according to specific circumstances; for example, the width can be 100mm and the height can be 60mm.

[0070] like Figure 2 or Figure 12 As shown, an upper steel beam 62 is installed at the upper end of flange 10 (the side away from the structural base plate 82), and a lower steel beam 61 is installed at the lower end of flange 10 (the side closer to the structural base plate 82). Both ends of the upper steel beam 62 and the lower steel beam 61 are welded to the steel columns 2 that serve as supporting pillars. The flange section is sealed using a flange caulking and sealing structure 12. In other words, the gaps in the space enclosed by the upper steel beam 62, the lower steel beam 61, flange 10, and the steel columns 2 on both sides of the steel pipe column 5 are filled using the flange caulking and sealing structure 12. This can be referred to... Figure 11 To understand this, we can use the following method. Optionally, in the embodiments of this application, the dimensions of the upper steel beam 62 and the lower steel beam 61 of the flange can be determined according to specific circumstances. For example, the width can be 100mm and the height can be 60mm.

[0071] In addition, refer to Figure 2 or Figure 9 or Figure 12 As shown, a non-standard modular plate 722 is installed between the steel beam 63 under the column cap and the steel beam 62 on the flange; a non-standard modular plate 712 is installed between the steel beam 61 under the flange and the second channel steel 42.

[0072] The technical solution provided in this application is illustrated below using a specific application scenario. Due to the constraints of the curved roof structure, the width of the first sub-panel partition wall is 7.1m in the direction perpendicular to the ground. The widths of the lower standard modular panel 71 and the middle standard modular panel 72 can be 2.45m, and the upper standard modular panel 73 has a curved roof surface. The steel column 2 can be a square steel column with a cross-section of 150mm in length and 100mm in width. In the direction perpendicular to the ground, the width of the first steel beam 3 can be 100mm, and the widths of the first steel channel 41 and the second steel channel 42 can both be 100mm. The first steel beam 3 is positioned at a height of 2.55m and 5.1m above the structural ground.

[0073] In addition, in this embodiment of the application, steel columns 2 can also be installed at the intersection of the partition walls and the two sides of the concentrated areas of fire doors and pipeline holes.

[0074] This application provides a modular assembly structure for panel partition walls in subway stations, applicable to subway stations with curved roofs and steel pipe columns.
