Abstract
Description
Technical Field
[0001] This invention relates to the field of building structures, and more specifically to a cross-track tunnel arch-supported shear wall system. Background Technology
[0002] Shear walls are the main walls in buildings or structures that bear horizontal loads and vertical loads (gravity) caused by wind loads or seismic forces, and are used to prevent structural shear failure. In recent years, with the increasing density of urban rail tunnel networks and the growing integration of rail transit with high-rise buildings, more and more buildings need to cross rail tunnels. Among these, high-rise shear wall structures place increasingly higher demands on the functionality and mixed-use of the lower floors. The lower floors often require large open-plan spaces, necessitating the minimization of vertical structural members in these areas.
[0003] The current construction of cross-track tunnel projects faces the following problems: 1. The transfer layer of cross-track tunnel projects involves multiple disciplines and requires extensive coordination, making it prone to errors in design drawings, which slows down the progress of the entire project and results in poor collaboration; 2. The floor heights and structural forms of the floors above and below the transfer layer of cross-track tunnel projects differ, which can easily cause abrupt changes in the stiffness of the main structure's bottom, resulting in weak layers. Furthermore, the large span of the vertical components under the cover restricts the arrangement of the vertical components due to the track; 3. The different construction structures above and below the transfer layer of cross-track tunnel projects often result in the reserved conditions for the buildings under the cover not meeting the requirements of the current design, leading to problems in the later development of the above-ground property.
[0004] The transformation involved in rail tunnel transportation superstructures often spans a much larger range than ordinary building projects, and how to rationally design this type of transformation structure has always been a challenge. Summary of the Invention
[0005] To address the aforementioned issues, this invention provides a cross-track tunnel arch-supported shear wall system with ample reserved space in the lower floors and strong load-bearing capacity of the main structure.
[0006] The technical solution of this invention is as follows: A cross-track tunnel arch-supported shear wall system includes a wall support structure, an arched transfer structure, and a vibration damping structure. The wall support structure includes frame-supported transfer columns and an upper shear wall. Two frame-supported transfer columns are arranged opposite to each other, and the upper shear wall is connected to the top of the two frame-supported transfer columns. The arched transfer structure includes an arched support beam and an intermediate floor beam. The arched support beam is erected between the two frame-supported transfer columns, and its two ends are respectively connected to the two frame-supported transfer columns. The middle part of the arched support beam arches upward to support the bottom of the upper shear wall. The intermediate floor beam is connected to both ends of the arched support beam. Several vibration damping structures are arranged between the intermediate floor beam and the arched support beam for vibration damping.
[0007] Furthermore, the arched transition structure includes a frame-supported transition beam, which is connected to two frame-supported transition columns and supports the upper shear wall.
[0008] Furthermore, each of the frame-supported transition columns includes a base section and a support section. The support section is erected on one side of the top surface of the base section, and a corresponding locking protrusion is formed between the top surface of the base section and the side surface of the support section. The locking protrusions of the two frame-supported transition columns are arranged opposite to each other, and the two ends of the arched support beam are respectively locked onto the corresponding locking protrusions.
[0009] Furthermore, the wall support structure includes cast-in-place piles, with two cast-in-place piles arranged opposite each other, upright on the ground, located below the frame-supported transition column, to support the frame-supported transition column.
[0010] Furthermore, the wall support structure includes support platforms, with two support platforms fixedly mounted on the top of the corresponding cast-in-place piles, and two frame-supported conversion columns erected on the corresponding support platforms.
[0011] Furthermore, the wall support structure includes a base plate concealed beam, which is connected to two support platforms, and several vibration damping structures are provided between the base plate concealed beam and the intermediate floor beam.
[0012] Furthermore, the wall support structure includes an upper floor beam, which passes through the upper shear wall and has its two ends passing through corresponding ground frame support conversion columns.
[0013] Furthermore, the vibration reduction structure includes embedded plates, inner support rods, and outer sleeves. The two embedded plates are respectively set on the bottom surface of the arched support beam and the top surface of the intermediate floor beam, and the outer sleeve is fitted on the outer periphery of the inner support rods.
[0014] Furthermore, the vibration damping structure includes a connecting plate and a reinforcing plate. The connecting plate is arranged parallel to the outer periphery of the inner support rod, and the reinforcing plate is connected to the bottom and top of the connecting plate, respectively. The two reinforcing plates are respectively connected to the embedded plate.
[0015] Furthermore, the vibration reduction structure includes pre-embedded anchor bars, which are respectively connected to two pre-embedded plates. The pre-embedded plates are respectively connected to the arched support beam and the intermediate floor beam through the pre-embedded anchor bars.
[0016] The beneficial effects of this invention are as follows:
[0017] First, compared with the normal cross-track tunnel transfer structure, this application can significantly reduce the amount of work for the wall support structure and the arch transfer structure, achieving the effect of saving construction materials and construction period, while the reserved space for the wall support structure and the arch transfer structure is large.
[0018] Second: This application utilizes the stress characteristics of the arched support beam, combined with the frame-supported transfer column, frame-supported transfer beam, bottom slab hidden beam, vibration damping components, and intermediate floor beams to form a coordinated stress system with strong load-bearing capacity. It successfully transmits the arched force through the arched support beam while ensuring the stability of the entire support structure, greatly reducing the construction difficulty and workload of the cross-track tunnel transfer section structure, and has significant economic benefits.
[0019] Third: Based on solving the problem of the conversion structure, this application adds a vibration reduction structure to the system. The vibration reduction effect is achieved through connecting plates and supporting inner rods, which effectively reduces the impact of vibration generated during train operation in the track tunnel on the superstructure.

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.
[0025] Please see Figure 1A cross-track tunnel arch-supported shear wall system includes a wall support structure 1, an arch-shaped transfer structure 2, and a vibration reduction structure 3. The wall support structure 1 includes a frame-supported transfer column 11 and an upper shear wall 12. The two frame-supported transfer columns 11 are arranged opposite to each other, and the upper shear wall 12 is connected to the top of the two frame-supported transfer columns 11. The arched transfer structure 2 includes an arched support beam 21 and an intermediate floor beam 22. The arched support beam 21 is erected between two frame-supported transfer columns 11, with its two ends connected to the two frame-supported transfer columns 11 respectively. The middle part of the arched support beam 21 arches upward to support the bottom of the upper shear wall 12, so that the vertical load of the upper shear wall 12 is distributed and transferred through the arched support beam 21. The arched support beam 21 and the frame-supported transfer columns 11 work together to bear the load of the upper shear wall 12, so as to achieve reasonable load distribution and avoid shear (shear) failure of the upper shear wall 12. The intermediate floor beam 22 is connected to both ends of the arched support beam 21, which plays a role in improving the stability of the arched support beam 21.
[0026] Furthermore, both ends of the intermediate floor beam 22 can pass through the arched support beam 21 and connect to the frame-supported transfer column 11 to improve the stability of the arched support beam 21 and correspondingly resist a portion of the horizontal tensile force generated by the arched support beam 21. Several vibration damping structures 3 are arranged between the intermediate floor beam 22 and the arched support beam 21 to reduce the vibration of the arched support beam 21 and prevent the arched support beam 21 from deforming under stress.
[0027] Each frame-supported transition column 11 includes a base section 111 and a support section 112. The base section 111 is fixed on the support platform 14, and the support section 112 is erected on one side of the top surface of the base section 111. Correspondingly, a locking protrusion 113 is formed between the top surface of the base section 111 and the side surface of the support section 112. The locking protrusions 113 of the two frame-supported transition columns 11 are arranged opposite to each other to provide space for installing the arched support beam 21. The two ends of the arched support beam 21 are respectively locked on the corresponding locking protrusions 113.
[0028] Specifically, please refer to Figure 2 The frame-supported transfer column 11 includes longitudinal reinforcement bars 114 and stirrups 115. A plurality of longitudinal reinforcement bars 114 are vertically inserted into the support platform 14; a plurality of stirrups 115 are spaced apart and fitted onto the longitudinal reinforcement bars 114; the frame-supported transfer column 11 is formed by pouring concrete between the longitudinal reinforcement bars 114 and the stirrups 115. Both the longitudinal reinforcement bars 114 and the stirrups 115 serve to strengthen the main structural strength of the frame-supported transfer column 11.
[0029] The arched support beam 21 includes longitudinal reinforcement bars 211 and stirrups 212. Both ends of the longitudinal reinforcement bars 211 are connected to the two frame-supported transfer columns 11, and the middle of each longitudinal reinforcement bar 211 arches upwards. The stirrups 212 are spaced apart and fitted onto the longitudinal reinforcement bars 211. Concrete is poured between the longitudinal reinforcement bars 211 and the stirrups 212 to form the arched support beam 21.
[0030] The wall support structure 1 includes cast-in-place piles 13 and support platforms 14. Two cast-in-place piles 13 are arranged opposite each other, upright on the ground, below the frame-supported transfer columns 11, to support the frame-supported transfer columns 11. The two cast-in-place piles 13 have large diameters and can withstand large loads. Two support platforms 14 are fixed to the tops of the corresponding cast-in-place piles 13 to support the frame-supported transfer columns 11. The two frame-supported transfer columns 11 are erected on the corresponding support platforms 14. The load of the upper shear wall 12 can be effectively transferred to the support platforms 14 through the frame-supported transfer columns 11 and the arched support beams 21; then transferred from the support platforms 14 to the cast-in-place piles 13. When the arched support beams 21 support the upper shear wall 12, the horizontal tensile force generated at their bottom is also transferred from the frame-supported transfer columns 11 to the support platforms 14.
[0031] The wall support structure 1 includes a base plate concealed beam 15, which is connected to two support platforms 14 to improve the stability of the two support platforms 14. Several vibration damping structures 3 are provided between the base plate concealed beam 15 and the intermediate floor beam 22 to reduce the vertical vibration of the intermediate floor beam 22.
[0032] Furthermore, the wall support structure 1 also includes an upper floor beam 16, which is transversely inserted into the upper shear wall 12, and both ends of the upper floor beam 16 pass through the frame-supported transfer column 11 to enhance the ability of the upper shear wall 12 to bear vertical loads.
[0033] Please see Figure 1 , Figure 3 The arched transition structure 2 includes a frame-supported transition beam 23, which is connected to the support section 112 of the two frame-supported transition columns 11 and supported at the bottom of the upper shear wall 12. It works in conjunction with the arched support beam 21 to bear the load of the upper shear wall 12. In this embodiment, the frame-supported transition beam 23 can be connected to the arched support beam 21, or it can be separately arranged side-by-side at intervals.
[0034] Specifically, the frame-supported transfer beam 23 includes longitudinal reinforcement 231 and stirrups 232. The two ends of the longitudinal reinforcement 231 are respectively connected to the two frame-supported transfer columns 11. The stirrups 232 are spaced out on the longitudinal reinforcement 231. Concrete is poured between the longitudinal reinforcement 231 and the stirrups 232 to form the frame-supported transfer beam 23.
[0035] Please see Figure 1 , Figure 4 The vibration damping structure 3 includes a pre-embedded plate 31, a supporting inner rod 32, and an outer sleeve 33. The two pre-embedded plates 31 are respectively set on the bottom surface of the arched supporting beam 21 and the top surface of the intermediate floor beam 22; or the two pre-embedded plates 31 are respectively set on the bottom surface of the intermediate floor beam 22 and the top surface of the bottom plate hidden beam 15. The supporting inner rod 32 is connected between the two pre-embedded plates 31 and plays the role of elastic support. The outer sleeve 33 is sleeved on the outer periphery of the supporting inner rod 32.
[0036] The vibration damping structure 3 includes a connecting plate 34 and a reinforcing plate 35. The connecting plate 34 is arranged parallel to the outer periphery of the inner support rod 32, and the reinforcing plate 35 is connected to its bottom and top ends respectively. The reinforcing plates 35 at both ends are connected to embedded plates 31 respectively. The connecting plate 34 cooperates with the inner support rod 32 to support the arched support beam 21 or the intermediate floor beam 22. The reinforcing plate 35 serves to strengthen the structure of the connecting plate 34, and the outer sleeve 33 is fitted onto the connecting plate 34.
[0037] Further, please refer to Figure 4 The vibration reduction structure 3 includes embedded anchor bars 36, which are respectively connected to two embedded plates 31. The embedded plates 31 are respectively connected to the arched support beam 21, the intermediate floor beam 22 and the bottom slab hidden beam 15 through the embedded anchor bars 36, so as to strengthen the structural strength between them.
[0038] In summary, the arch-supported shear wall system of this invention achieves arch force transmission through the arch support beam 21, and works in conjunction with the frame-supported transfer column 11, frame-supported transfer beam 23, bottom slab hidden beam 15, vibration damping components, and intermediate floor beam 22 to achieve coordinated force transmission. It has strong load-bearing capacity and structural stability. Furthermore, the reserved space in the wall support structure 1 and the arch-supported transfer structure 2 is large, which facilitates subsequent construction. The vibration damping effect is achieved through the connecting plate 34 and the inner support rod 32 of the vibration damping structure 3, reducing the impact of vibration generated during the operation of the track tunnel train on the upper shear wall 12 and other structures.
