Description

Technical Field

[0001] The invention belongs to the field of station engineering design, and in particular relates to a discontinuous middle longitudinal beam arrangement method for a two-column, three-span, three-layer island-type station. Background Art

[0002] Reference Figure 1 Two rows of frame columns are arranged along the longitudinal direction of the station. The cross-section of the structure with two columns, three spans and three layers is called the two-column, three-span and three-layer structure of the station. If the station is a three-story underground station, the platform slab is usually located in the middle of the station, and the running tracks are set on both sides.

[0003] With the continuous deepening of urban rail transit construction, underground three-story stations and T-type transfer stations have become key design nodes in urban rail transit design, and are also key locations for passenger flow gathering and dispersion. In the design of traditional underground three-story stations and T-type transfer stations, in order to ensure that the station structure is simple in force, the force transmission is clear, and the force continuity along the longitudinal direction of the station is ensured, longitudinal beams are usually set along the length of the station on the top, middle, and bottom plates of the station, and the station structure is reasonably divided into two spans, three spans, or multiple spans.

[0004] Among them, in the arrangement of beams and columns for three-story underground stations and T-type transfer stations, in order to ensure that the total width of the station is minimized and the width of the shielding doors at the station hall level meets the regulatory requirements, the problem of too small intermediate horizontal span makes it difficult to arrange the escalators and vertical elevators side by side, making it difficult to optimize the passenger flow of the station; at the same time, if the escalators and vertical elevators are dispersed, and there are too many dispersed openings in the middle plate, it will also have an adverse effect on the middle plate of the station.

[0005] Therefore, a new technology is needed to solve the problem that escalators and vertical elevators are difficult to be arranged side by side in the two-column, three-span, three-layer island station in the prior art. Summary of the invention

[0006] In order to solve the above problems in the prior art, the present invention provides a discontinuous middle longitudinal beam arrangement method for a two-column, three-span, three-story island station, and a reasonably optimized beam-column arrangement form, so that escalators and vertical elevators can be arranged side by side.

[0021] S23. According to the opening space requirement of the vertical elevator, the first middle longitudinal beam is offset and set at the edge of the hole.

[0022] Furthermore, the S3 step includes the following steps:

[0023] S31, setting and fixing the support brackets of the transverse force conversion beam and the hole edge beam; wherein the transverse force conversion beam comprises a first transverse force conversion beam and a second transverse force conversion beam; and the hole edge beam comprises a first hole edge beam and a second hole edge beam;

DETAILED DESCRIPTION

[0041] The following will be combined with the embodiments and drawings to clearly and completely describe the concept, specific structure and technical effects of the present invention, so as to fully understand the purpose, scheme and effect of the present invention. It should be noted that the embodiments in this application and the features in the embodiments can be combined with each other without conflict. The same reference numerals used throughout the drawings indicate the same or similar parts.

[0042] It should be noted that, unless otherwise specified, when a feature is referred to as being "fixed" or "connected" to another feature, it may be directly fixed or connected to the other feature, or it may be indirectly fixed or connected to the other feature. In addition, the descriptions of up, down, left, right, etc. used in the present invention are only relative to the relative positional relationship of the components of the present invention in the drawings.

[0043] Reference Figure 1 , it can be seen that the two-column, three-span, three-story island station structure has two rows of frame columns 1 arranged along the longitudinal direction of the station, and its cross section (i.e. Figure 1 ) is a two-column, three-span, three-story structure, of which the first floor is the F floor, the second floor is the S floor, and the third floor is the T floor.

[0044] Reference Figures 1 to 3 A non-continuous middle longitudinal beam arrangement method for a two-column, three-span, three-story island station, characterized in that it includes the following steps:

[0045] S1. Determine the installation positions of the vertical elevator 3 and the escalator 4, install the vertical elevator 3 and the escalator 4 together, and set a hole 8 matching the top of the vertical elevator 3 and the escalator 4 on the middle plate 7;

[0046] S2, interrupting the first middle longitudinal beam 21 that conflicts with the position of the vertical elevator 3, and shifting the interrupted first middle longitudinal beam 21 to the side of the hole 8;

[0047] S3, setting a transverse force transfer beam 5 and a hole edge beam 6;

[0048] S4. Complete the arrangement.

[0049] The present invention arranges the vertical elevator 3 and the escalator 4 together, and reasonably opens a matching hole 8 on the third layer T layer middle plate 7, reducing the influence of too many scattered holes on the middle plate 7 on the stability of the structure of the middle plate 7, and optimizing the stress condition of the middle plate 7. The vertical elevator 3 and the escalator 4 are centrally arranged together, which optimizes the shortcomings of the previous vertical elevator 3 and the escalator 4 being dispersed, and can ensure a larger passenger flow distribution space in the public area.

[0050] The present invention improves the continuous middle longitudinal beam, optimizes the local beam system, and ensures the overall force of the station; the present invention cuts off the local single-span middle longitudinal beam, sets it offset at the edge of the hole, and sets transverse force conversion beams at both ends of the middle longitudinal beam of the span, and closes the edge of the middle longitudinal beam of the span, so that it transfers the load to the frame column as a load-bearing member. This improvement only changes the structure and force transfer form of the local single-span beam, and has little effect on the remaining span beams, ensuring the rationality of the force after the local structure is adjusted. The layout of the present invention has little effect on the existing station scale and structural form, and has good versatility.

[0051] In one embodiment, the step S1 comprises the following steps:

[0052] S11, determine the coordinate positions of the vertical elevator 3 and the escalator 4;

[0053] S12, arranging the vertical elevator 3 and the escalator 4 side by side and / or in parallel horizontally;

[0054] S13, a hole 8 is opened on the middle plate 7, and the hole 8 is in an inverted "L" shape, and the hole 8 matches the vertical elevator 3 and the escalator 4.

[0055] Furthermore, in the step S11, the coordinate position includes a horizontal coordinate, a vertical coordinate and a vertical elevation.

[0056] like Figure 2, taking the positive angle end of the third frame column 13 as the origin O coordinate, the longitudinal direction of the continuous middle longitudinal beam 22 is defined as the direction of the Y coordinate, and the direction of the X coordinate is defined as the direction of the horizontal and perpendicular direction of the Y coordinate through the origin O coordinate. In this step S1, the plane coordinates (X, Y) of the vertical elevator 3 and the escalator 4 set on the second layer S are determined, which are the plane horizontal coordinate X and the plane vertical coordinate Y respectively; after determining the plane coordinates (X, Y), the vertical elevator 3 and the escalator 4 are set side by side and / or aligned together, and the vertical elevation of the vertical elevator 3 and the escalator 4 is determined at the same time, so as to prepare for the subsequent interruption of the first middle longitudinal beam 21 and the offset of the first middle longitudinal beam 21, and also for the subsequent setting of the hole side beam. In this step S1, the vertical elevator 3 and the escalator 4 are set side by side and / or aligned together, and the corresponding hole 8 coordinates are determined on the middle plate 7 of the third layer T layer, and the hole is opened after determination to complete the establishment of the hole 8, which will match the vertical elevator 3 and the escalator 4. In one embodiment, the hole is in an inverted "L" shape.

[0057] In one embodiment, the S2 step includes the following steps:

[0058] S21, setting and fixing the support bracket of the first middle longitudinal beam 21;

[0059] S22, interrupting the first middle longitudinal beam 21 that conflicts with the position of the vertical elevator 3;

[0060] S23, according to the opening space requirement of the vertical elevator, the first middle longitudinal beam is offset and set at the edge of the hole;

[0061] In this step S2, specifically, the interrupted first middle longitudinal beam 21 is translated by the corresponding plane horizontal coordinate X distance. In one embodiment, the interrupted first middle longitudinal beam 21 is offset in the positive direction of the X axis by at least one-third of its own beam width, and the offset first middle longitudinal beam 21 is set at the edge of the hole. In one embodiment, the interrupted first middle longitudinal beam 21 is offset laterally by half of its own beam width, and the offset first middle longitudinal beam is set at the edge of the hole.

[0062] In one embodiment, the S3 step includes the following steps:

[0063] S31, setting and fixing the support brackets of the transverse force conversion beam 5 and the hole side beam 6; in detail, the transverse force conversion beam 5 includes a first transverse force conversion beam 51 and a second transverse force conversion beam 52; the hole side beam 6 includes a first hole side beam 61 and a second hole side beam 62;

[0064] S32, set a first transverse force conversion beam 51, connect one end of the first transverse force conversion beam 51 to the sub-span beam 24 on the first frame column 11, and connect the other end to the first outer structure 91; in detail, in one embodiment, half of the end of the first middle longitudinal beam A after being broken is connected to the sub-span beam 24 of the non-continuous middle longitudinal beam, and the other half of the end of the first middle longitudinal beam A after being broken is connected to the first transverse force conversion beam 51; the first transverse force conversion beam 51 after being set is kept horizontal;

[0065] S33, set a second transverse force transfer beam 52, connect one end of the second transverse force transfer beam 52 to the main span beam 23 on the second frame column 12, and connect the other end to the first outer structure 91; in detail, in one embodiment, half of the end of the first middle longitudinal beam B after being broken is connected to the main span beam 23 of the non-continuous middle longitudinal beam, and the other half of the end of the first middle longitudinal beam B after being broken is connected to the second transverse force transfer beam 52; the second transverse force transfer beam 52 after being set is kept horizontal;

[0066] S34, set the first hole side beam 61, connect one end of the first hole side beam 61 to the interrupted first middle longitudinal beam 21, and the other end of the first hole side beam 61 to the continuous middle longitudinal beam 22; in detail, the first hole side beam 61 after setting is kept horizontal; according to the opening space requirements of the vertical elevator 3 and the escalator 4, the first hole side beam 61 is set at the hole edge. In one embodiment, one end of the first hole side beam 61 is connected to the middle of the interrupted first middle longitudinal beam 21, and the other end is horizontally connected to the corresponding continuous middle longitudinal beam;

[0067] S35, set the second hole side beam 62, connect one end of the second hole side beam 62 to the main span beam 23 of the non-continuous middle longitudinal beam, and the other end of the second hole side beam 62 to the middle longitudinal beam 22 of the continuous beam; in detail, the second hole side beam 62 after setting is kept horizontal; according to the opening space requirements of the escalator 4, the second hole side beam 62 is set at the hole edge; in one embodiment, when the second hole side beam 62 is connected to the middle longitudinal beam, if the end can be extended horizontally, it will stand on the frame column, and this design can achieve better load-bearing and force-transmission of the structure. In one embodiment, the end of the second hole side beam 62 has half the beam width, if it can be extended, it will stand on the frame column.

[0068] In this step S3, the outer structure 9 includes a first outer structure 91 and a second outer structure 92. In another embodiment, the vertical elevator 3 and the escalator 4 can also be interchanged horizontally. Accordingly, the continuous middle longitudinal beam of the corresponding span will be interrupted and the corresponding transverse force conversion beam 5 and hole edge beam 6 will be set. At this time, the other end of the transverse force conversion beam 5 will be connected to the second outer structure 92. Specifically, the first hole edge beam 61 and the second hole edge beam 62 will improve the structural stability of the middle plate 7 after the hole is opened.
