Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of hanging beam type frame pier, specifically relates to a hanging beam type frame pier for rail transit construction. BACKGROUND

[0002] With the large-scale construction of high-speed railway and common speed railway, the small angle intersection of new line and existing railway and highway is inevitable, especially in the more prosperous city, with the land shortage, and more and more municipal traffic channels and railway lines, the multi-channel intersection in the three-dimensional space is also more and more common.

[0003] The beam body of the frame pier is generally supported on the cross beam, due to the large building height, the insufficient clearance problem is prone to occur under the restriction of multiple control points. The hanging beam type frame pier can effectively deal with these complex terrains and urban environment, and provide more flexible and reliable support structure, such as the railway and the track traffic hanging beam type frame pier disclosed in Chinese patent CN 206956534U, the building height is lower, and the problems of land shortage and space limitation are solved.

[0004] However, since the hanging beam type frame pier needs to disperse and bear various loads generated during the operation of rail transit, including the self weight of train, dynamic impact force, etc., and the existing hanging beam type frame pier is mostly supported by spaced piers, the structural strength at different positions is different, when the pressure or dynamic impact force is large, the frame pier structure is prone to structural deformation or damage risk, especially the middle position of the cross beam is prone to collapse or fracture due to large pressure. UTILITY MODEL CONTENT

[0005] In view of one or more deficiencies of the prior art, the utility model provides a hanging beam type frame pier for rail transit construction, which can improve the structural strength and support stability, reduce the structural deformation and damage risk, and solve one or more technical problems of the prior art.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0007] A hanging beam type frame pier for rail transit construction, comprising two support columns and a cross beam at the top of the support column, an arched pressure bearing beam is fixedly installed between the two support columns, the dome of the arched pressure bearing beam is embedded in the cross beam and fixedly connected, so as to disperse the pressure or impact force received by the cross beam to the two support columns, and ensure the stability and safety of the structure.

[0008] As a further implementation mode, two first clamping interfaces are symmetrically formed in the bottom of the cross beam, and the top of the support column is inserted into and clamped into the first clamping interface.

[0009] As a further implementation manner, a first gap is arranged between the support column and the cross beam.

[0010] As a further implementation manner, the bottom of the arch-shaped pressure bearing beam is embedded into the support column and fixed by pouring.

[0011] As a further implementation manner, a second clamping interface is arranged on the inner side of the support column and is embedded with the arch-shaped pressure bearing beam.

[0012] As a further implementation manner, a second gap is arranged between the end of the arch-shaped pressure bearing beam and the inner wall of the second clamping interface.

[0013] As a further implementation manner, the arch top of the arch-shaped pressure bearing beam is arranged at the middle part of the cross beam to ensure that the structure is uniformly stressed.

[0014] As a further implementation manner, a first column base is fixedly installed at the bottom end of the support column, and the first column base is arranged below the ground to improve the stability of the support column.

[0015] As a further implementation manner, a second column base is fixedly connected with the support column and is arranged above the first column base, and the second column base is arranged below the ground and parallel to the first column base to form a I-shaped structure and further improve the structural strength.

[0016] As a further implementation manner, a side support column is fixedly installed on the side surface of the support column, and the side support column is arranged outside the support column in a triangular structure and is arranged on the ground.

[0017] By adopting the above technical scheme, the utility model has the following beneficial effects:

[0018] 1. In the utility model, the cross beam can transmit the longitudinal pressure generated by the track to the support column and the arch-shaped pressure bearing beam, the arch-shaped pressure bearing beam has an arch-shaped structure, the area in the middle part of the cross beam which is subjected to relatively large pressure and impact can be evenly distributed to the two support columns, the collapse or fracture of the middle part of the cross beam due to the relatively large pressure can be avoided, and the risk of structural deformation and damage caused by uneven stress can be reduced.

[0019] 2. In the utility model, the first column base, the second column base and the support column form a I-shaped structure, the soil below the ground is filled between the first column base and the second column base, the first column base and the second column base are subjected to pressure and supporting force, the support column can be stably fixed on the ground, the lateral impact force caused by the train operation can be avoided to cause the support column to be inclined, the pressure intensity generated by the support column on the ground can be reduced, the collapse of the support column caused by the relatively large pressure can be avoided, and the structural strength is effectively improved.

[0020] 3. In this utility model, the supporting columns, arched load-bearing beams, and crossbeams are considered to undergo thermal expansion and contraction when the external ambient temperature changes. Therefore, the arched load-bearing beams and crossbeams are connected to the supporting columns through a second locking interface and a first locking interface, respectively. This can prevent the components from being stretched during contraction, thus avoiding changes in internal stress and affecting the stability of the structure. Furthermore, the arched load-bearing beams and crossbeams are connected to the supporting columns through a second gap and a first gap, respectively. This provides additional space for the components during thermal expansion, preventing them from being squeezed and cracking, ensuring the stability of the structure, and thus improving the service life of the structure.

[0030] It should be noted that the terminology used herein is for descriptive purposes only and is not intended to limit the exemplary embodiments according to this invention. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0031] Example 1

[0032] In one typical embodiment of this application, a suspended beam frame pier for rail transit construction is provided, such as... Figures 1-6 As shown, the structure includes two supporting columns 1 and a crossbeam 3 at the top of the supporting columns. An arched pressure-bearing beam 2 is fixedly installed between the two supporting columns 1. The arch top of the arched pressure-bearing beam 2 is embedded in the crossbeam 3 and fixedly connected, which can distribute the pressure or impact force on the crossbeam to the two supporting columns, ensuring the stability and safety of the structure.

[0033] Specifically, such as Figure 1 As shown, there is a certain gap between the two supporting columns 1. The crossbeam 3 is fixedly installed at the top of the two supporting columns 1, and the arched supporting column 2 is installed between the two supporting columns 1. Its arched top is embedded upward into the middle of the crossbeam 3 and fixedly connected, which can support the middle of the crossbeam and ensure uniform stress. In this embodiment, the frame pier body formed by the two supporting columns 1, the arched supporting column 2 and the crossbeam 3 is an axisymmetric structure, which can effectively ensure the structural strength and stability of the support, better cope with larger pressure and dynamic impact, and reduce the risk of structural deformation and damage caused by uneven stress.

[0034] Furthermore, such as Figure 2 As shown, a first column base 6 is fixedly installed at the bottom of the supporting column 1. A second column base 5, which is fixedly connected to the supporting column, is installed on the upper part of the first column base 6. The second column base 5 is arranged parallel to the first column base 6 and both are located below the ground 11, forming an I-shaped structure. The soil below the ground 11 fills the space between the first column base 6 and the second column base 5, which can apply pressure and support to the first column base and the second column base, thereby making the supporting column stably fixed on the ground and avoiding the lateral impact force brought by the train running, which would cause the supporting column to tilt. At the same time, it can also reduce the pressure of the supporting column on the ground, preventing the supporting column from collapsing due to excessive pressure, and greatly improving the structural strength.

[0035] Furthermore, in combination Figure 3 ,5 As shown, two first locking interfaces 7 are symmetrically opened at the bottom of the crossbeam 3. The first locking interfaces 7 cooperate with the top of the support column 1. The top of the support column 1 can be inserted and locked into the first locking interfaces 7 and fixed by casting. This can prevent the components from being stretched when the crossbeam or support column is cooled and contracted due to environmental factors, so as to avoid changes in internal stress and affect the stability of the structure. In this embodiment, a first gap 8 is formed between the first locking interfaces 7 of the support column 1 and the crossbeam after the fixed connection. This can provide additional accommodation space for the components when thermal expansion occurs, avoid the components from being squeezed and cracked, ensure the stability of the structure, and thus improve the service life of the structure.

[0036] Furthermore, in combination Figure 4 , 6 As shown, the inner sides of the two supporting columns 1 are respectively provided with second locking interfaces 9. The second locking interfaces 9 cooperate with the arched bearing beam 2. The bottom sides of the arched bearing beam 2 are inserted into the second locking interfaces 9 and fixed by casting. At the same time, a second gap 10 is formed between the fixedly connected arched bearing beam 2 and the second locking interfaces 9, which has the same effect as the first locking interface and the first gap.

[0037] In this embodiment, the support column 1, the arched pressure beam 2, and the crossbeam 3 are connected by a segmented casting method.

[0038] In addition, such as Figure 1 , 2 As shown, a side support column 4 is fixedly installed on the side of the support column 1. The side support column 4 is arranged in a triangular structure on the outside of the support column 1. The bottom of the side support column 4 is fixedly installed on the ground 12 to further improve the stability of the support column.

[0039] The construction process and working principle of this embodiment are as follows:

[0040] During construction, the main structure of the supporting column 1, the first column base 6, and the second column base 5 are first constructed using steel reinforcement. Then, the slabs are used to build a casting mold, and concrete is poured into the mold to complete the construction of the supporting column 1. Next, the arched bearing beam 2 and the crossbeam 3 are poured sequentially using the same method. Specifically, the arched bearing beam 2 is poured first, followed by the crossbeam 3, with the bottom of the crossbeam 3 covering the arched top of the arched bearing beam. In use, the crossbeam 3 can transfer the longitudinal pressure generated by the track to the supporting column 1 and the arched bearing beam 2. The arched structure of the arched bearing beam 2 can evenly distribute the pressure and impact on the central area of ​​the crossbeam 3 to the two supporting columns 1, preventing collapse or breakage of the central part of the crossbeam 3 due to excessive pressure. The first column base 6, the second column base 5, and the supporting column 1 form an I-shaped structure. The soil below the ground 11 fills the space between the first column base 6 and the second column base 5, which can stably fix the supporting column 1 to the ground 11, preventing the supporting column 1 from tilting due to the lateral impact force brought by the train running. At the same time, it can also reduce the pressure of the supporting column 1 on the ground 11, preventing the supporting column 1 from collapsing due to excessive pressure, thus achieving the effect of improving the structural strength.

[0041] When the external ambient temperature changes, the supporting column 1, the arched bearing beam 2, and the crossbeam 3 will undergo thermal expansion and contraction. The arched bearing beam 2, the crossbeam 3, and the supporting column 1 are connected by the second clamping interface 9 and the first clamping interface 7. The supporting column 1, the arched bearing beam 2, and the crossbeam 3 are not directly connected, which can prevent the components from being stretched during thermal contraction, thus avoiding changes in internal stress and affecting the stability of the structure. At the same time, the second gap 10 and the first gap 8 formed between the supporting column 1 and the arched bearing beam 2 and the crossbeam 3 can provide additional space for each component during thermal expansion, preventing the components from being squeezed and cracking, which would affect the stability of the structure and thus improve the service life.

[0042] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it. Those skilled in the art should understand that this utility model can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
