Description

Technical Field

[0001] This invention relates to the field of building construction technology, and in particular to a sliding device suitable for connecting corridors between buildings of different heights. Background Technology

[0002] A connecting corridor is a structure that connects buildings, often used for elevated connections between high-rise buildings, serving multiple functions such as passage, lighting, and viewing. A curtain wall is the exterior wall cladding of a building, a lightweight wall with decorative effects commonly used in high-rise buildings. It usually does not have a load-bearing capacity, and in existing buildings, the boundaries of the curtain wall are usually connected to the connecting corridor with rigid components to form an integrated structure.

[0003] However, for connecting corridors in high-seismic-intensity areas, the different heights of the buildings connected at both ends of the corridor result in significant differences in settlement. During settlement, the buildings on both sides of the corridor can easily compress the structures around the pre-installed expansion joints, causing damage or detachment of building envelope components such as curtain walls located below the expansion joints. This not only reduces the overall aesthetics of the building and weakens the corridor's seismic performance but also compromises the overall safety and structural durability of the building.

[0004] Therefore, there is an urgent need to propose a sliding device suitable for connecting corridors between buildings of different heights to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a sliding device suitable for connecting corridors between buildings of different heights, which can reduce the impact of uneven settlement on the connecting corridors and curtain walls, extend the service life of the connecting corridors and curtain walls, improve the overall structural durability of the building, and ensure the overall aesthetics and safety of the building.

[0006] To achieve this objective, the present invention adopts the following technical solution: This invention proposes a sliding device suitable for connecting corridors between buildings of different heights. The corridor is located between a first building body and a second building body of different heights, with both ends of the corridor connected to the first building body and the second building body, respectively. An expansion joint is provided between the curtain wall of the first building body and the corridor. The sliding device suitable for connecting corridors between buildings of different heights is located below the expansion joint and includes: a supporting body that can be fixedly connected to the first building body; and a sliding support, including a first sliding member, a second sliding member, and a support body. The first sliding member and the second sliding member are spaced apart in the horizontal direction and both extend in the vertical direction. The first sliding member is connected to the supporting body, the second sliding member can be connected to the corridor, and the support body is sandwiched between the first sliding member and the second sliding member. The first sliding member or the second sliding member is slidably connected to the support body.

[0007] Optionally, the support body includes a support member, a first support brace, and a second support brace. The support member extends horizontally and can be fixed to the first building body. The first support brace and the second support brace are spaced apart horizontally and are both set at an angle to the horizontal plane. The end of the first support brace away from the second support brace is connected to the first end of the support member in the horizontal direction. The end of the second support brace away from the first support brace can be connected to the connecting corridor. The two ends of the first sliding member in the vertical direction are respectively connected to the first support brace and the support member. The two ends of the second sliding member in the vertical direction are respectively connected to the second support brace and the connecting corridor.

[0008] Optionally, the sliding device for connecting corridors between buildings of different heights also includes a sliding auxiliary component. The sliding auxiliary component includes a first sliding auxiliary component, a second sliding auxiliary component, and a sliding base. The first sliding auxiliary component is connected to the second end of the support member in the horizontal direction. The second sliding auxiliary component can be connected to the connecting corridor. The first and second sliding auxiliary components are spaced apart in the horizontal direction and both extend in the vertical direction. The sliding base is sandwiched between the first and second sliding auxiliary components. The first or second sliding auxiliary component is slidably connected to the sliding base.

[0009] Optionally, the first sliding auxiliary component is disposed on the side of the second sliding auxiliary component that is horizontally away from the first building body, and the height of the first sliding auxiliary component is higher than the height of the second sliding auxiliary component.

[0010] Optionally, the surface of the first sliding auxiliary member away from the second sliding auxiliary member may be provided with a curtain wall panel decorative layer or a patterned plate.

[0011] Alternatively, the outer surface of the curtain wall panel decorative layer or patterned plate may be flush with the outer surface of the curtain wall.

[0012] Optionally, the sliding support may also include an elastic buffer element disposed between the upper end of the first sliding member and the connecting corridor; and / or, the elastic buffer element disposed between the lower end of the second sliding member and the support member.

[0013] Optionally, the outer periphery of the sliding support is provided with an elastic seal.

[0014] Alternatively, the support body can be made of polytetrafluoroethylene (PTFE).

[0015] Alternatively, the supporting structure can be made of steel.

[0016] The beneficial effects of this invention are: This invention proposes a sliding device suitable for connecting corridors between buildings of different heights. A first sliding member is connected to a support member fixed to the main body of the first building, and a second sliding member is connected to the connecting corridor. Either the first or second sliding member is slidably connected to a support body located between them. This structural arrangement allows the first or second sliding member, positioned below the expansion joint of the first building, to slide relative to the support body when uneven settlement occurs at the two ends of the connecting corridor. This addresses the issue of uneven settlement causing the connecting corridor to directly impact the structure. For rigidly connected curtain walls, the sliding support proposed in this invention allows the connecting corridor to undergo relative displacement with the curtain wall near the expansion joint. This avoids directly forcibly pulling the end of the connecting corridor when the main building has a large settlement, which would cause the end of the connecting corridor to deform and compress the curtain wall portion of the main building below the expansion joint. The sliding device proposed in this invention, applicable to connecting corridors between buildings of different heights, effectively reduces the impact of uneven settlement on the connecting corridor and curtain wall, extends the service life of the connecting corridor and curtain wall, and thus improves the overall structural durability of the building, ensuring the overall aesthetics and safety of the building. The supporting body is fixedly connected to the main building, the first sliding member is connected to the supporting body, and the second sliding member is connected to the connecting corridor. The supporting body and the connecting corridor can provide stable support for the sliding process of the first or second sliding member relative to the supporting body, enhancing the sliding safety and reliability of the first or second sliding member.

[0022] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0023] like Figures 1-2As shown, this embodiment provides a sliding device suitable for connecting corridors between buildings of different heights. The connecting corridor 100 is disposed between a first building body 200 and a second building body 300 of different heights. The two ends of the connecting corridor 100 are respectively connected to the first building body 200 and the second building body 300. An expansion joint 400 is provided between the curtain wall 500 of the first building body 200 and the connecting corridor 100. The sliding device suitable for connecting corridors between buildings of different heights is disposed below the expansion joint 400 and includes a supporting body 1 and a sliding support 2. The supporting body 1 is fixedly connected to the first building body 200. The sliding support 2 includes a first sliding member 21, a second sliding member 22, and a support body 23. The first sliding member 21 and the second sliding member 22 are spaced apart in the horizontal direction and both extend in the vertical direction. The first sliding member 21 is connected to the supporting body 1, and the second sliding member 22 can be connected to the connecting corridor 100. The support body 23 is sandwiched between the first sliding member 21 and the second sliding member 22, and either the first sliding member 21 or the second sliding member 22 is slidably connected to the support body 23. It should be noted that in this embodiment, the height of the first building body 200 is higher than the height of the second building body 300, and a connecting corridor embedded plate 110 is provided at the bottom of the connecting corridor 100. The second sliding member 22 can be connected to the connecting corridor embedded plate 110.

[0024] In this embodiment, the first sliding member 21 is connected to the support member 11 fixed to the first building body 200, and the second sliding member 22 is connected to the connecting corridor 100. Either the first sliding member 21 or the second sliding member 22 is slidably connected to the support body 23 located between the two. Through the above structural arrangement, when uneven settlement occurs at both ends of the connecting corridor 100 due to the connection of the first building body 200 and the second building body 300 with different heights, the first sliding member 21 or the second sliding member 22 located near the expansion joint 400 of the higher first building body 200 can slide relative to the support body 23. That is, compared with the prior art, the connecting corridor 100 is directly affected by uneven settlement. Regarding the curtain wall 500, which is rigidly connected to it, the sliding support 2 proposed in this embodiment enables the connecting corridor 100 to generate relative displacement with the curtain wall 500 near the expansion joint 400. This avoids directly forcibly pulling the end of the connecting corridor 100 when the first building main body 200 has a large settlement, which would cause the end of the connecting corridor 100 to deform and squeeze the curtain wall 500 part of the first building main body 200 located below the expansion joint 400. The sliding support 2 proposed in this embodiment effectively reduces the impact of uneven settlement on the connecting corridor 100 and the curtain wall 500, extends the service life of the connecting corridor 100 and the curtain wall 500, and thus improves the overall structural durability of the building, ensuring the overall aesthetics and safety of the building. The support body 1 is fixedly connected to the first building body 200, the first sliding member 21 is connected to the support body 1 and the second sliding member 22 is connected to the connecting corridor 100. The support body 1 and the connecting corridor 100 can provide stable support for the sliding process of the first sliding member 21 or the second sliding member 22 relative to the support body 23, thereby enhancing the sliding safety and sliding reliability of the first sliding member 21 or the second sliding member 22.

[0025] Specifically, the material of the support body 1 includes steel. Steel itself has the characteristics of high hardness and high structural strength. The material of the support body 1 including steel effectively enhances the support effect of the support body 1 on the sliding support 2, and ensures the sliding stability and sliding reliability of the first sliding member 21 or the second sliding member 22 that is slidably connected to the support body 23.

[0026] For example, the support body 23 is made of polytetrafluoroethylene (PTFE). PTFE has low friction and high lubricity properties, as well as excellent resistance to acids and alkalis and high temperatures. It has a long service life and is suitable for construction operations in various harsh environments. The use of PTFE in the support body 23 significantly reduces the sliding difficulty between the first sliding member 21 or the second sliding member 22 and the support body 23. Furthermore, the low friction of PTFE reduces frictional wear between the first sliding member 21 or the second sliding member 22 and the support body 23, ensuring the structural integrity and strength of the sliding support 2.

[0027] Optionally, the supporting body 1 includes a supporting member 11, a first supporting diagonal brace 12, and a second supporting diagonal brace 13. The supporting member 11 extends horizontally and can be fixed to the first building body 200. The first supporting diagonal brace 12 and the second supporting diagonal brace 13 are spaced apart horizontally and are both set at an angle to the horizontal plane. The end of the first supporting diagonal brace 12 away from the second supporting diagonal brace 13 is connected to the first end of the supporting member 11 in the horizontal direction. The end of the second supporting diagonal brace 13 away from the first supporting diagonal brace 12 can be connected to the connecting corridor 100. The two ends of the first sliding member 21 in the vertical direction are respectively connected to the first supporting diagonal brace 12 and the supporting member 11. The two ends of the second sliding member 22 in the vertical direction are respectively connected to the second supporting diagonal brace 13 and the connecting corridor 100. The support member 11 extends horizontally and is fixed to the first building body 200. The first support diagonal brace 12 is set at an angle to the horizontal plane. The two ends of the first sliding member 21 in the vertical direction are connected to the support member 11 and the first support diagonal brace 12 respectively. With the help of the first support diagonal brace 12 and the support member 11, the first sliding member 21 is stably supported in both the horizontal and vertical directions, which improves the installation stability of the first sliding member 21 and the load-bearing strength of the first sliding member 21 during the subsequent settlement of the first building body 200, and extends the service life of the first sliding member 21. The second supporting diagonal brace 13 is set at an angle to the horizontal plane. The connecting corridor 100 extends horizontally. The two ends of the second sliding member 22 in the vertical direction are connected to the second supporting diagonal brace 13 and the connecting corridor 100, respectively. With the help of the supporting member 11 and the second supporting diagonal brace 13, the second sliding member 22 is stably supported in both the horizontal and vertical directions, which improves the installation stability of the second sliding member 22 and the load-bearing strength of the second sliding member 22 during the subsequent settlement of the first building main body 200, and extends the service life of the second sliding member 22. The supporting member 11, the first supporting diagonal brace 12 and the second supporting diagonal brace 13 work together to enhance the structural reliability and durability of the sliding support 2, and extend the overall service life of the sliding device applicable to connecting corridors between buildings of different heights.

[0028] It should be noted that in this embodiment, the support member 11 and the connecting corridor embedded plate 110 are parallel to each other and spaced apart in the vertical direction. The connecting corridor embedded plate 110 is set above the support member 11. The second support diagonal brace 13 is connected to the connecting corridor 100 through the connecting corridor embedded plate 110. The sliding support 2 is sandwiched between the support member 11 and the connecting corridor embedded plate 110, which improves the installation stability of the sliding support 2.

[0029] For example, the support member 11 is a steel plate to ensure the support strength and stability of the first support brace 12 and the first sliding member 21. The thickness of the steel plate is between 8mm and 12mm to further improve the support effect on the first support brace 12 and the first sliding member 21. In this embodiment, the thickness of the steel plate is 10mm.

[0030] Optionally, the sliding device applicable to the connecting corridor between buildings of different heights also includes a sliding auxiliary component 3. The sliding auxiliary component 3 includes a first sliding auxiliary component 31, a second sliding auxiliary component 32, and a sliding base 33. The first sliding auxiliary component 31 is connected to the second end of the support member 11 in the horizontal direction. The second sliding auxiliary component 32 can be connected to the connecting corridor 100. The first sliding auxiliary component 31 and the second sliding auxiliary component 32 are spaced apart in the horizontal direction and both extend in the vertical direction. The sliding base 33 is sandwiched between the first sliding auxiliary component 31 and the second sliding auxiliary component 32. The first sliding auxiliary component 31 or the second sliding auxiliary component 32 is slidably connected to the sliding base 33. The above structural design enables the sliding support 2 to work in conjunction with the sliding auxiliary component 3 when the first building body 200 and the second building body 300 experience uneven settlement. That is, during uneven settlement, one of the first sliding component 21 and the second sliding component 22 can slide relative to the support body 23, and one of the first sliding auxiliary component 31 and the second sliding auxiliary component 32 can slide synchronously relative to the sliding seat 33. The addition of the sliding auxiliary component 3 not only improves the overall sliding stability of the sliding device applicable to corridors between buildings of different heights during uneven settlement, but also reduces the requirement for the maximum sliding path of the first sliding component 21 or the second sliding component 22, reduces the overall space occupancy of the sliding support 2, and improves the installation convenience of the sliding device applicable to corridors between buildings of different heights.

[0031] Specifically, the first sliding auxiliary component 31 is disposed on the side of the second sliding auxiliary component 32 that is horizontally away from the first building body 200, and the height of the first sliding auxiliary component 31 is higher than the height of the second sliding auxiliary component 32. The placement of the first sliding auxiliary component 31 avoids interference from the second supporting diagonal brace 13 during its installation and sliding process, ensuring the load-bearing reliability of the first sliding auxiliary component 31 when the first building body 200 and the second building body 300 settle unevenly. The higher height of the first sliding auxiliary component 31 compared to the second sliding auxiliary component 32 allows the sliding process of either the first sliding auxiliary component 31 or the second sliding auxiliary component 32 to proceed smoothly during uneven settlement, achieving a synergistic dispersion effect of the sliding auxiliary component 3 and the sliding support 2 on the uneven settlement load.

[0032] In some embodiments, a curtain wall panel decorative layer is provided on the surface of the first sliding auxiliary member 31 away from the second sliding auxiliary member 32, that is, a curtain wall panel decorative layer is provided on the outer surface of the first sliding auxiliary member 31, which realizes the consistency of appearance between the first sliding auxiliary member 31 and the curtain wall 500 and improves the structural aesthetics of the exposed part of the first sliding auxiliary member 31.

[0033] In some other embodiments, the surface of the first sliding auxiliary member 31 away from the second sliding auxiliary member 32 may also be provided with a patterned plate. The patterned plate is a steel plate with a pattern on its surface, which is used to meet the construction requirements of the external enclosure structure in areas with large temperature differences.

[0034] Furthermore, the outer surface of the decorative layer or patterned plate of the curtain wall panel is flush with the outer surface of the curtain wall 500, which not only improves the overall appearance consistency between the sliding support 2 and the curtain wall 500 and ensures the overall aesthetics of the building structure, but also avoids the risk of stress concentration in at least part of the sliding support 2 or the curtain wall 500 when the outer surfaces of the two are not on the same vertical plane.

[0035] Optionally, the sliding support 2 further includes an elastic buffer, which is disposed between the upper end of the first sliding member 21 and the connecting corridor 100; and / or, the elastic buffer is disposed between the lower end of the second sliding member 22 and the support member 11. The presence of elastic buffers at at least one location between the upper end of the first sliding member 21 and the connecting corridor 100, and between the lower end of the second sliding member 22 and the support member 11, can absorb some of the load applied to the first sliding member 21 or the second sliding member 22 due to uneven settlement of the first building main body 200 and the second building main body 300. This reduces the load-bearing capacity of the first sliding member 21 and the second sliding member 22, extends the service life of the first sliding member 21 and the second sliding member 22, improves the structural durability of the first sliding member 21 and the second sliding member 22, and reduces the maintenance costs and load-bearing requirements of the first sliding member 21 and the second sliding member 22.

[0036] For example, an elastic seal 4 is provided on the outer periphery of the sliding support 2. The elastic seal 4 provides a sealing effect for the sliding support 2, preventing erosion of the sliding support 2 by factors such as rainwater or water seepage at the connecting corridor 100, improving the protection effect of the sliding support 2, and extending the structural life of the sliding support 2.

[0037] In this embodiment, before the large-scale construction of the curtain wall 500 of the first building body 200, the support member 11 needs to be pre-embedded in the first building body 200. Then, the pre-embedded plate and its frame of the curtain wall 500 are set on the first building body 200. After that, the second support brace 13 is welded on the pre-embedded plate 110 of the connecting corridor to connect the second support brace 13 and the second sliding member 22. The first support brace 12 is welded on the support member 11 to connect the first sliding member 21 and the first support brace 12, so as to realize the installation of the sliding support 2. After the sliding support 2 is installed, a large-scale construction of the surface material of the curtain wall 500 is carried out. The second sliding auxiliary component 32 is welded at the pre-embedded plate 110 of the connecting corridor, and the first sliding auxiliary component 31 is welded at the support component 11. A sliding seat 33 is installed between the first sliding auxiliary component 31 and the second sliding auxiliary component 32. After the sliding auxiliary component 3 and the sliding support 2 are installed, elastic sealing components 4 are set on their outer periphery to improve the sealing effect of the two. Finally, the curtain wall panel decorative layer or patterned plate is set on the outer surface of the first sliding auxiliary component 31 so that the outer surface of the curtain wall panel decorative layer or patterned plate is flush with the outer surface of the curtain wall 500, ensuring the overall flatness and external aesthetics of the building.

[0038] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here.
