Definitions
- the present invention relates to rail transit, and is a track structure applied to modern high-speed rail transit, and particularly applicable to magnetic levitation high-speed rail transit.
- the track beam spans between two buttresses and forms the entire line one by one. Since modern high-speed rail transit systems such as magnetic levitation trains run at high speeds, the system has exceptionally high accuracy requirements for the line structure, requiring that the line's deformation and deflection under the action of temperature differences and live loads should be controlled within a small range.
- the deflection or overarching of the track beam caused by temperature differences or moving loads is not a problem in traditional bridges, and for the traveling tracks of modern high-speed rail vehicles, especially in magnetic levitation tracks, these temperature differences or activities
- the small deformation caused by the load will affect the high-speed operation of the train.
- the continuous beam has superior structural performance compared with two simply-supported beams of equal section in controlling the deformation caused by temperature difference or active load.
- the track beam is generally constructed by prefabrication and then erected. Because of its huge size and weight, and because the multi-span continuous beam is an external statically indeterminate structure with multi-point support, the state of multi-point support must always be maintained during transportation and lifting, and the relative displacement of any of its fulcrum points is uniform. The beam must be controlled in a small area to ensure the safety of the beam itself. Otherwise, the entire beam can easily be damaged during the entire construction process.
- the reaction force of the support of the continuous beam in the middle pier is generally much larger than that of the simply supported beam.
- its resistance to vertical reaction forces is better.
- the increase in vertical reaction forces is not sensitive to the increase in the cost of the underlying foundation, and the ability to resist horizontal reaction forces is often poor. Smaller increases in horizontal reaction forces caused by the structure Will cause a substantial increase in the underlying foundation materials. This is especially true for soft ground.
- the patent DE19936756 uses the method of embedding guide screws and tooth structure when positioning the two beam sections. Because the guide screw and the tooth structure are formed before the concrete is poured or positioned during the pouring, even if two adjacent beam segments are cast simultaneously, the alignment of the adjacent beam segments relative to the position of the concrete member can only be guaranteed.
- the precise positioning of their spatial positions refers to the continuous alignment of the phase positions between the functional surfaces of the rail. These functional surfaces are determined after the prefabrication of the concrete body of the track beam, and subsequent machining and fine assembly of the continuous parts and functional surfaces. The dimensions of the original beam members have been corrected by reducing or refilling the materials.
- the technical problem to be solved by the present invention is to overcome the shortcomings of the above-mentioned prior art, and to provide a track structure suitable for high-speed rail transit. More specifically, it is a structure in which a plurality of simple supported beams are connected into a multi-span quasi-continuous beam. In order to make full use of the advantages of continuous beams, which have less deformation under the influence of temperature differences and active loads, the difficulties of prefabrication, processing, transportation and installation of continuous beams with large volumes and weights are overcome.
- each beam section of the track beam between each support pier is prefabricated, processed, transported, installed, accurately positioned in the form of a simply supported beam, and then every two (or more) spans are erected Connect to the plane (that is, around the Y axis) so that the bending stiffness is as large as possible, close to the structural form of the continuous beam, and in the horizontal direction (that is, about the Z axis), connect so that the bending stiffness is as small as possible, close to the hinged one.
- a quasi-continuous beam in the form of a two-span or multi-span simply-supported beam structure one by one
- a track structure of a high-speed rail transit includes two or more beam sections, which is characterized in that a steel intermediate part and a beam intermediate part are embedded in the transverse middle part of the beam top and the beam bottom at the connection end of the beam section, and are A number of anchors that ensure the reliable combination of the embedded part with the concrete of the beam section. After the connection ends of the two beam sections are placed close to each other, multiple bolts are passed through the screw holes of the connector and the screw holes of the embedded part to form a quasi-continuous beam. ;
- the beam section may be a solid beam section or a hollow beam section (including the cavity 3);
- the embedded part is a concave steel plate
- the concave embedded part is also provided with a rolled wire inclined anchor for applying prestress;
- the concave embedded part provided with the rolled wire oblique anchor is also provided with a horizontal anchor rib;
- the post-tensioned prestressing tendons are also used to press the recessed embedded parts embedded in the top of the beam at the connection end of the beam section, so that the embedded parts are more tightly and firmly combined with the beam section;
- the beam section is a reinforced concrete beam
- the beam section is a prestressed concrete beam
- connection between the connecting part and the embedded part can also be connected by a hard connection method
- the connection mechanism will be more simplified.
- Bolts or rigid joints can be used to directly connect the connector with the upper roof of the two steel structure beam sections or the lower part of the two steel structure beam sections.
- the bottom plates are connected together;
- the upper and lower connectors are placed on the inner sides of the upper and lower floor plates in the abdominal cavity of the steel beam, respectively;
- the connecting member can have various shapes, such as a plate type (connection steel plate), a block type, a column type or a tube type.

- FIG. 2 is a schematic structural diagram of a track beam formed by connecting two concrete beam sections in Embodiment 1 of the present invention, which is a horizontally hinged, nearly continuous two-span track beam structure in a vertical plane, and please refer to FIGS. 3 to 7.
- This embodiment is composed of concrete beam sections 1 and 2.
- the beam sections are hollow web beams containing cavities 3.
- the beam sections 1 and 2 are prepared with prestressing ribs 5.
- the connection structure of the two beam sections 1 and 2 is formed by a concave preform. Buried steel connecting pieces (referred to as embedded parts) 6.
- the vertical anchors 7, the connecting steel plates 8 and the bolts 9 are firmly connected to the embedded parts 6.
- the beam can also be The anchor point of the post-tensioned tendon 5 at the connection end of the segments 1 and 2 is moved upward to press the embedded part 6, as shown in FIG. 3, which is equivalent to applying a certain preload to the embedded part 6.
- the embedded parts 6 are arranged at the beam top and the beam bottom at the connection ends of the beam sections 1 and 2.
- the connection steel plates 8 are two pieces, which are also placed at the middle of the beam top and the beam bottom at the connection end of the beam. Relying on the corresponding screw holes of the embedded parts 6 and the connecting steel plate 8, the two beam segments 1 and 2 are connected together by using bolts 9.
- this structure can ensure that the horizontal bending stiffness of the connection node is far less than the vertical plane bending stiffness, the former is less than 5% of the latter, and it is ideally achieved that: two (or more) beams ,
- the connection in the vertical plane is approximately continuous, and the connection between the sections in the horizontal plane still maintains the design concept of approximate articulation, that is, the beam sections in the vertical plane have been connected into two or more span continuous beams In the horizontal plane, the beams are still simply supported one by one.
- the calculated and measured structure shows that the structure of the present invention is very close to the performance of controlling the temperature difference between upper and lower and the deformation caused by the active load compared with a completely continuous multi-span continuous beam.
- connection method for connecting the steel plate 8 and the embedded part 6 made of the steel plate may be a welding connection method (welding wire 12) or a bolt 9 connection method.
- Bolt connection can be divided into two types: refined bolt connection and high-strength bolt connection. If a high-strength bolt connection is adopted, the two veneers connecting the steel plate 8 and the concave embedded steel plate 6 shall be treated by sandblasting and other processes according to the requirements of the friction surface of the high-strength bolt connection of the steel structure.
- the connecting steel plates 8 are not closely attached when they are connected, which affects the force transmission effect.
- flames can be used to slightly correct (twist) the middle of the connecting steel plates 8 during construction to make the The buried steel plates 6 can be closely adhered, that is, the torsional deformation of the connecting steel plates 8 is adopted to conform to the spatial positioning of two adjacent beam sections to ensure that the originally accurately positioned beams are not displaced by the connection between the beam sections.
- connection structure of the present invention can lock the connection steel plate 8 under a selected temperature difference or a deformed state of the beam section, it can play a role of fine-tuning the above deformation difference, so that the deformation difference caused by various factors is controlled to be small. Within the range, to achieve the purpose of optimal train comfort.
- the method and structure of the present invention can be used to loosen the connection between the beam sections, and the beam caused by the temperature difference

- the track structure on which the train is running continuously maintains the dimensional tolerance requirements required by the system during its entire service life.
- FIG. 8 is a structural schematic diagram of Embodiment 2 of the present invention—two sections of steel structure beam sections 11 and 12 connected into a track beam, the structure is more simplified, and only the connecting steel plate 8 needs to be directly connected to the steel structure beam with bolts 9 or welding.
- the upper top plate 14 and the lower bottom plate 15 of the sections 11 and 12 are sufficient. See FIG. 9.
- the embedded parts 6 and corresponding anchors when the concrete beam sections 1 and 2 are connected may be omitted, such as the vertical anchors 7 and the horizontal anchors.
- the upper and lower connecting steel plates 8 can also be placed on the inner side of the upper top plate 14 and the lower bottom plate 15 of the abdominal cavity 3 of the steel beam, as shown in FIG. 10.
- the present invention has the following improved technical effects:
