Description

Technical Field

[0001] The utility model relates to the technical field of corridor bearings, and particularly relates to a seismic corridor structure. Background Technique

[0002] At present, steel structures are increasingly widely used in the construction industry, and building shapes are changing with each passing day. In order to facilitate traffic and the aesthetic appearance of the facade between two buildings, steel structure corridors are often used to connect adjacent towers. When an earthquake occurs, for the two towers connected by a corridor, there may be vibrations in the same direction or in the opposite direction. When the steel corridor beam is laterally connected to the tower structure, the steel beam will limit the relative value of the horizontal displacement of the two towers, which has a great impact on the stiffness, bearing capacity and overall structural regularity of the main structure. Therefore, measures need to be taken to reduce the impact of corridor components on the stiffness of the main structure.

[0003] In order to reduce the adverse effects of the corridor on the building structures on both sides, the joints connecting the corridor to the main structure are usually set as sliding bearings. The traditional method of sliding bearings is to directly use rubber bearings. This method has a high construction difficulty, and it cannot ensure that the steel beam does not tip over and slide under large earthquake actions. In addition, due to the poor shear resistance of the rubber body, it is prone to shear failure and is easy to age, and it is very difficult to repair and replace. Content of the Utility Model

[0004] The purpose of the utility model is to provide a seismic corridor structure to solve the above deficiencies in the prior art.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A seismic corridor structure includes a concrete corbel and a corridor steel beam. A seismic protection support assembly is arranged between the corbel and the steel beam. The seismic protection support assembly includes a buried plate embedded in a groove on the corbel. A fixed cylinder is arranged on the buried plate. A sliding seat is slidably arranged on the fixed cylinder. The sliding seat is detachably connected to the lower side of the steel beam. The sliding seat slides on the fixed cylinder to reduce the influence of the steel beam on the corbel.

[0007] Further, the sliding seat includes a sliding plate slidably arranged on the fixed cylinder. A connecting rod is fixedly connected to the sliding plate. The connecting rod passes through an opening on the fixed cylinder and extends into a limiting groove in the fixed cylinder. A clamping plate is fixedly connected to the end of the connecting rod.

[0008] Further, the limiting groove, the opening and the clamping plate are all circularly arranged.

[0009] Further, the diameter of the clamping plate is larger than the opening.

[0010] Further, a safety distance is provided between the clamping plate and the upper side, lower side, and side wall of the inner wall of the fixed cylinder.

[0011] Further, a polytetrafluoroethylene plate is provided on the lower side of the sliding plate.

[0012] Further, the sliding plate and the steel beam are connected by bolts.

[0013] In the above technical solution, the beneficial effects of an anti-seismic connecting corridor structure provided by the present utility model are as follows:

[0014] Through the provided anti-seismic support assembly, when an earthquake occurs, the tower drives the concrete corbel to vibrate. The vibration of the corbel drives the fixed cylinder to vibrate through the embedded plate. The vibration of the fixed cylinder causes a relative displacement between it and the sliding seat. Whether the two towers connected by the connecting corridor vibrate in the same direction or in the opposite direction, the sliding seat still maintains the support for the steel beam, weakening the influence of the connecting corridor on the structural stiffness of the tower caused by the vibration of the tower during an earthquake.

[0015] It should be understood that the foregoing general description and the following detailed description are merely exemplary and explanatory, and are not intended to limit the present disclosure.

[0024] To make the objectives, technical solutions and advantages of the embodiments of the present disclosure clearer, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present disclosure. Apparently, the described embodiments are some, but not all, of the embodiments of the present disclosure. All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present disclosure without creative efforts shall fall within the scope of protection of the present disclosure.

[0025] Please refer to Figures 1-4 , an anti-seismic corridor structure, including a concrete corbel 1 and a corridor steel beam 2. A seismic support assembly 3 is arranged between the corbel 1 and the steel beam 2. The seismic support assembly 3 includes an embedded plate 31 embedded in a groove on the corbel 1. A fixed cylinder 32 is arranged on the embedded plate 31. A sliding seat 4 is slidably arranged on the fixed cylinder 32. The sliding seat 4 is detachably connected to the lower side of the steel beam 2. The sliding seat 4 slides on the fixed cylinder 32 to reduce the influence of the steel beam 2 on the corbel 1.

[0026] Through the arranged seismic support assembly 3, when an earthquake occurs, the tower drives the concrete corbel 1 to vibrate. The vibration of the corbel 1 drives the fixed cylinder 32 to vibrate through the embedded plate 31. The vibration of the fixed cylinder 32 causes a relative displacement between it and the sliding seat 4. Whether the two towers connected by the corridor vibrate in the same direction or in the opposite direction, the sliding seat 4 still maintains the support for the steel beam 2, weakening the influence of the corridor on the structural stiffness of the tower caused by the vibration of the tower during an earthquake.

[0027] Further, the sliding seat 4 includes a sliding plate 41 slidably arranged on the fixed cylinder 32. A connecting rod 42 is fixedly connected to the sliding plate 41. The connecting rod 42 passes through an opening 43 on the fixed cylinder 32 and extends into a limiting groove 44 inside the fixed cylinder 32. And a clamping plate 45 is fixedly connected to the end of the connecting rod 42.

[0028] Further, the limiting groove 44, the opening 43 and the clamping plate 45 are all circularly arranged. This design enables the fixed cylinder 32 to move in any direction within the plane. Therefore, when the tower vibrates, the sliding seat 4 does not restrict the movement of the fixed cylinder 32.

[0029] Further, the diameter of the clamping plate 45 is larger than that of the opening 43. Thus, when the tower has a vertical displacement, the clamping plate 45 is prevented from moving out of the opening 43, resulting in unstable support of the steel beam 2.

[0030] Furthermore, a safety distance is provided between the upper side, the lower side and the side wall of the inner wall of the clamping plate 45 and the fixed cylinder 32. According to the specific situation of the project, the force analysis of the two tower models under the action of a major earthquake can be carried out to obtain the total relative displacement of the two towers at this elevation position, and the maximum horizontal displacement of the fixed cylinder 32 can be obtained, so as to determine the safety distance.

[0031] Furthermore, a polytetrafluoroethylene plate (not shown in the figure) is provided on the lower side of the sliding plate 41. The polytetrafluoroethylene plate has an extremely low friction coefficient and good self-lubricating performance, which can reduce the friction between the sliding plate 41 and the upper side of the fixed cylinder 32.

[0032] Furthermore, the sliding plate 41 is bolted to the steel beam 2.

[0033] Working principle: When an earthquake occurs, the tower drives the concrete corbel 1 to vibrate. The vibration of the corbel 1 drives the fixed cylinder 32 to vibrate through the embedded plate 31. The vibration of the fixed cylinder 32 causes a relative displacement between it and the sliding seat 4. Whether the two towers connected by the corridor vibrate in the same direction or in the opposite direction, the sliding seat 4 still maintains the support for the steel beam 2, weakening the influence of the corridor on the structural stiffness of the tower caused by the vibration of the tower during the earthquake.

[0034] Only some exemplary embodiments of the present invention have been described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, the described embodiments can be modified in various different ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of the claims of the present invention.
