Description

Technical Field

[0001] The invention belongs to the field of suspended monorails, and in particular relates to a beam-pier connection structure of a suspended monorail. Background Art

[0002] The monorail system is a common rail transit system. Together with the subway system and the light rail system, it constitutes the three most common types of urban rail transit. In the monorail system, according to the different running modes and track structures, it is mainly divided into suspended monorail and straddled monorail.

[0003] Among them, the suspended monorail transportation system is a new type of lightweight, small and medium-capacity urban rail transit form. It is gradually becoming more and more popular in the new rail transit field, especially in the tourism field, due to its small structural volume and good sightseeing experience.

[0004] At present, the standard beams of suspended monorail operating lines and test lines at home and abroad mainly adopt two types of pier-beam connection forms: support connection and pin connection. Among them, the support connection requires the use of a corbel structure through the pier top cap beam and the top of the track beam to convert the tension into pressure, and the pier-beam connection is achieved by setting supports between the corbels. Its structure is complex, the number of supports is large, the amount of steel used is large, the aesthetics is poor, and the track beam replacement and maintenance are difficult. The pin connection is to set an ear plate at the bottom of the pier top cap beam and the top of the track beam, and pass the pin through the ear plate to achieve the pier-beam connection. Its structure is simple and the construction is fast, but the stress concentration effect is obvious near the pin hole of the ear plate. Usually, a steel plate with a thickness of more than 60mm is used to alleviate the stress concentration phenomenon, which puts high requirements on the welding of components. Summary of the invention

[0005] In response to one or more of the above defects or improvement needs in the prior art, the present invention provides a beam-pier connection structure for a suspended monorail, which can effectively achieve the connection between the track beam and the cap beam by setting a beam-pier connection structure composed of steel components, stiffening ribs and connecting parts.

[0014] As a further improvement of the present invention, a transverse reinforcement plate is further provided on the cap beam, and the transverse reinforcement plate is arranged in the transverse direction on the side plate or the bottom plate of the cap beam.

[0015] As a further improvement of the present invention, the track beam comprises a box beam, and a plurality of transverse partitions are arranged at intervals on the outer periphery of the box beam extending between two adjacent cap beams.

[0016] As a further improvement of the present invention, a sliding sheet is further provided between the bottom of the corbel and the top surface of the bottom plate.

[0017] As a further improvement of the present invention, the sliding plate has a variety of optional specifications for adjusting the elevation of the track beam under different setting requirements.

[0040] Example:

[0041] See also Figures 1 to 5 The beam-pier connection structure in the preferred embodiment includes a bridge pier 1, a cap beam 2 and a track beam 3, and the track beam 3 is correspondingly connected to the cap beam 2 through a beam-pier connection assembly 5, and the load from the track beam 3 and the load borne by the track beam 3 are transferred to the bridge pier 1 through the beam-pier connection assembly 5. At the same time, in the preferred embodiment, the running direction of the suspended train 4 is the longitudinal direction, and the horizontal direction perpendicular to the longitudinal direction is the transverse direction. Therefore, a plurality of beam-pier connection structures are arranged at intervals in the longitudinal direction to achieve stable support of each section of the track beam 3.

[0042] Specifically, the bridge pier 1 in the preferred embodiment is used to bear the load on the cap beam 2 and the track beam 3. The bottom of the bridge pier 1 is fixedly arranged, and the cap beam 2 is arranged on the top of the bridge pier 1 in the transverse direction. Figure 1The "T-shaped" symmetrical structure shown in the figure, that is, track beams 3 are respectively arranged under the two ends of the cap beam 2. In actual setting, the setting dimensions of the pier 1 and the cap beam 2 are preferably set according to the size and range of the load borne on the cap beam 2, which will not be repeated here.

[0043] Furthermore, in the preferred embodiment, the bottom of both ends of the cap beam 2 are respectively provided with track beams 3, and the track beam 3 includes a box beam 301 extending in the longitudinal direction, and the bottom of the box beam 301 is opened in the longitudinal direction, which is used to achieve the matching of the suspended monorail train and the internal running mechanism of the track beam 3 and the running of the suspended train 4; and the box beam 301 is provided with a diaphragm 302 in the circumferential direction except the bottom. At the same time, the diaphragms 302 are arranged in a plurality of intervals in the axial direction (i.e., longitudinal direction) of the track beam 3, and the diaphragms 302 in the preferred embodiment are arranged perpendicular to the peripheral beam wall of the track beam 3, that is, the diaphragms 302 are connected to the beam wall with side walls, and the two end faces of the diaphragms 302 are respectively perpendicular to the peripheral beam wall of the correspondingly connected track beam 3. In addition, the diaphragms 302 and the box beam 301 are connected by welding, and the structural arrangement of the diaphragms 302 can also enhance the structural strength of the box beam 301.

[0044] Furthermore, the cap beam 2 in the preferred embodiment is arranged for the track beam 3, and its end portion is a hollow box beam structure. A through hole is opened in the transverse direction through the upper and lower end surfaces of the bottom plate 201 on the bottom plate 201 of the cap beam 2 corresponding to the diaphragm 302 of the track beam 3, for the insertion of the top diaphragm 302 of the track beam 3. At the same time, a corbel is arranged inside the cap beam 2 corresponding to the diaphragm 302 inserted therein, and the corbel is composed of two corbels arranged on both sides of the diaphragm 302, for connecting the diaphragm 302 and transferring the load on the diaphragm 302 to the bottom plate 201 of the cap beam 2. In the preferred embodiment, the corbel includes an "L-shaped" steel member 501 and a plurality of stiffening ribs 502 arranged on the steel member 501, such as Figure 4 As shown in . One side fold of the steel member 501 is close to the diaphragm 302, and the other side fold is supported on the bottom plate 201 of the cap beam 2, and the stiffening ribs 502 are respectively connected to the two folds of the steel member 501 with their sides, so as to ensure the structural stability of the steel member 501 and avoid deformation of the structure of the steel member 501. Specifically, the diaphragm 302 extending into the interior of the cap beam 2 is connected to the corbels on both sides through a plurality of connectors 503, that is, the connectors 503 pass through the two steel members 501 and the diaphragm 302 sandwiched between the two steel members 501, so as to achieve a reliable connection between the diaphragm 302 and the two corbels. In actual setting, the connectors 503 are multiple and spaced apart in the transverse and longitudinal directions, such as Figure 3 As shown in , the connecting member 503 in the preferred embodiment may further preferably be a bolt.

[0045] Furthermore, a slide 504 is provided between the bottom plate 201 and the steel member 501. Figure 4As shown in , the slide 504 can cause relative displacement between the steel member 501 and the bottom plate 201 to release the internal force generated by temperature changes. At the same time, in order to make the elevation of the track beam 3 reach the design value (i.e., adjust the relative elevation of the cap beam and the track beam), it is necessary to adjust the distance between the steel member 501 and the bottom plate 201. In a preferred embodiment, the slide 504 is 1 mm thick, and the distance is adjusted by stacking multiple slides 504 layer by layer; in another preferred embodiment, as shown in FIG. Figure 5 As shown, it increases the distance between the steel member 501 and the bottom plate 201 by using a trapezoidal slide 505 with downwardly folded edges at both ends. Therefore, in actual settings, slides of corresponding specifications can be used according to actual conditions to adjust the relative elevations of the cap beam and the track beam, so that the elevation of the track beam 3 reaches the design value.

[0046] At the same time, since at least one through hole is opened in the middle of the bottom plate 201 in the horizontal direction, and the bottom plate 201 needs to bear the pressure load transmitted by the corbel during actual operation, the force stability of the bottom plate 201, especially the force stability at the opening, is at risk. In view of this, in the preferred embodiment, a vertical reinforcing plate 203 is correspondingly arranged on one or both sides of the horizontal opening of the bottom plate 201. The vertical reinforcing plate 203 is preferably arranged parallel to the longitudinal direction, and its outer peripheral wall surface is correspondingly connected to the inner peripheral wall surface of the cap beam 2 to form an integral structure.

[0047] Further preferably, a transverse reinforcing plate 202 is further provided inside the cap beam 2. The transverse reinforcing plate 202 is arranged to extend in the transverse direction and is connected to the vertical reinforcing plate 203 and the inner wall surface of the cap beam 2. Figure 2 , 3 As shown in , the overall structural strength of the cap beam 2 can be further improved. In addition, a bottom plate stiffening rib is provided below the bottom plate 201, which preferably extends in the transverse direction and is connected to the bottom of the bottom plate 201 with a side wall, which can improve the local stiffness of the bottom plate 201 and resist the local deformation of the bottom plate 201.

[0048] In actual configuration, the track beam 3 at the bottom of the cap beam 2 can be a continuous beam structure, or adjacent track beams 3 can be butted at their ends below the cap beam 2. For example, in a preferred embodiment, a continuous track beam 3 is disposed at the bottom of the cap beam 2, and the diaphragm 302 corresponding to the cap beam 2 can be a single one, or a plurality of not less than two, which can be optimized according to the stress conditions of the track beam 3. In another preferred embodiment, two sections of track beams 3 are butted at their ends below the cap beam 2. At this time, at least one diaphragm 302 is respectively disposed on the outer periphery of the ends of the track beams 3 at both ends, which is used to extend into the cap beam 2 for corresponding connection; for example Figure 2 As shown in FIG. 1 , a transverse partition 302 is respectively provided at the ends of the two track beams 3 .

[0049] The beam-pier connection structure of the suspended monorail in the present invention can effectively meet the operation needs of the suspended monorail train by providing a beam-pier connection assembly with a corbel as the main structure, and transfer the load borne by the connection structure to the cap beam and the pier in the form of pressure, thereby ensuring the stability and safety of the suspended monorail transportation.

[0050] It will be easily understood by those skilled in the art that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
