Description

Technical Field

[0001] The invention belongs to the technical field of building engineering, and relates to a structure and method for an escalator and staircase to jointly pass through a seismic isolation layer. Background Art

[0002] In recent years, more and more new buildings or renovations of existing buildings have adopted seismic isolation technology to improve the seismic performance of the structure, and have achieved excellent seismic resistance. Seismic isolation buildings are equipped with a relatively soft seismic isolation layer. While being able to isolate the earthquake, they also cause a large horizontal displacement between the seismic isolation layer and the non-seismic isolation layer under the action of the earthquake. Especially under the action of rare earthquakes, the horizontal displacement often reaches 400-600mm, which poses a great challenge to the transportation facilities that pass through the seismic isolation layer and the non-seismic isolation layer.

[0003] In the prior art, the method usually adopted for escalators to pass through the seismic isolation layer and the non-seismic isolation layer is as follows: a non-seismic isolation platform raised by the non-seismic isolation layer is provided at the higher end of the escalator, the escalator is placed on the non-seismic isolation platform, and then the non-seismic isolation platform of the escalator is connected to the seismic isolation upper main structure by overlapping and crossing the seismic isolation trench by means of plate overlap, such as Figure 1 As shown. The method usually adopted for the walking stairs to pass through the seismic isolation layer and the non-seismic isolation layer is: within the height range of the seismic isolation support, a horizontal through-slit is set, the stairs above the horizontal slit are fixed to the seismic isolation main structure, and the stairs below the horizontal slit are fixed to the non-seismic isolation structure, including auxiliary components such as railings and handrails. When an earthquake occurs, due to the existence of the horizontal slit, the upper seismic isolation structure can deform freely, thereby achieving the purpose of normal use and coping with earthquake deformation, as shown in the figure. Figure 1 , 2 , as shown in Figure 3.

[0004] However, in large public buildings, escalators and stairs are often arranged in parallel, such as in public buildings such as railway stations, terminal buildings, subway stations, and large shopping malls. However, since the deformable part of the escalator passing through the seismic isolation layer and the non-seismic isolation layer is near the floor, and the deformable part of the staircase passing through the seismic isolation layer and the non-seismic isolation layer is within the height range of the seismic isolation support below the floor beam, when the escalator and the staircase are parallel and pass through the seismic isolation layer and the non-seismic isolation layer, the deformable part of the staircase and the deformable part of the escalator are displaced up and down in height, resulting in interference and conflict between the deformable part of the staircase and the non-deformable part of the escalator under the action of an earthquake, and even a destructive effect of mutual damage, which brings great safety hazards.

[0005] Therefore, a safer and more reliable building structure or construction method in which escalators and stairs pass through the seismic isolation layer together is needed to solve the above problems. Summary of the invention

[0006] The technical solution adopted by the present invention to solve the technical problem is: a structure for escalators and stairs to jointly pass through the isolation layer, including: escalators, stairs, upper isolation layer, lower non-isolation layer. The upper isolation layer and the lower non-isolation layer are connected by isolation bearings. The upper exits of the escalators and stairs are docked with the upper isolation layer, and the lower exits of the escalators and stairs are docked with the lower non-isolation layer. The escalators and stairs are arranged side by side, in the same direction and with the same slope. On the ground of the lower non-isolation layer, there is a support platform rising from the ground. The bottoms of the upper exits of the escalators and stairs are both located on the support platform. The escalators, stairs, the lower non-isolation layer and the support platform together form a right triangle structure in the vertical plane. There is an isolation joint reserved horizontally between the upper exits of the escalators and stairs and the upper isolation layer. The upper exits of the escalators and stairs are overlapped with the upper isolation layer through a sliding cover plate, and the sliding cover plate spans and covers the isolation joint; the support platform is in the shape of a "door", there is a cross beam on the top of the support platform, and on the ground of the lower non-isolation layer, there are columns supporting the bottom of the cross beam from bottom to top; the upper exits of the escalators and stairs are jointly supported by the support platform, so that the deformable parts of the stairs and the deformable parts of the escalators are combined into one place, avoiding the interference and conflict that are likely to occur between the deformable parts of the stairs and the non-deformable parts of the escalators under the action of an earthquake.

[0007] Preferably, the cross beam includes a horizontal straight cross beam and a stepped cross beam. The horizontal straight cross beam has good rigidity but is not conducive to adjusting the different support heights of the escalators and stairs, while the stepped cross beam meets the needs of different support heights of the escalators and stairs, making it more convenient and quick to adjust the support height.

[0008] Preferably, between the bottom surfaces of the upper exits of the escalators and stairs and the upper surfaces of the cross beam, there are respectively escalator support piers and stair support piers; the escalator support piers and stair support piers can conveniently and quickly adjust the different heights of the support piers caused by the fact that there is a horizontal platform at the upper exit of the escalator while there is often no horizontal platform at the upper exit of the stairs.

[0009] More preferably, both the escalator support piers and the stair support piers are made of elastic materials. The support piers made of elastic materials can eliminate the mutual vibration influence between the escalators and stairs.

[0010] Preferably, on the ground of the lower non-isolation layer, there is also an auxiliary support platform rising from the ground. The auxiliary support platform supports the bottoms of the escalators and stairs from bottom to top, and the support points of the auxiliary support platform are located between the upper and lower exits of the escalators and stairs; the auxiliary support platform can provide better stability and reliability when the escalators and stairs are relatively long.

[0011] Preferably, the width of the isolation joint is not less than 60 cm; the isolation joint can effectively prevent the upper exits of the escalators and stairs from being squeezed against the building edge during an earthquake, causing damage to the building or the escalators and stairs.

[0012] Preferably, the sliding cover plate is a slidable cover plate whose length can be telescoped along the pedestrian direction; since the slidable cover plate can be telescoped along the pedestrian direction, it does not affect the lapping of the sliding cover plate in the case of a small horizontal displacement caused by a minor earthquake. In addition, the sliding cover plate can not only meet the floor flatness requirements during normal use, but also meet the requirements that the seismic isolation joint and the cover plate can deform freely when an earthquake comes, without structural or equipment damage.

[0013] The present invention also discloses a method for escalators and stairs to jointly cross the seismic isolation layer. The method adopts the above-mentioned structure for crossing the seismic isolation layer, and the method includes the following steps:

[0014] Step 1: According to actual needs, determine the common upper exit position of the escalator and the stairs at the upper seismic isolation layer and the common lower exit position at the lower non-seismic isolation layer; after determining the positions, preprocess the upper and lower exit positions of the upper seismic isolation layer and the lower non-seismic isolation layer.

[0015] Step 2: According to the lifting height, inclination angle, and step width of the escalator and the stairs, determine the horizontal position, vertical support height, size, and material of the support platform fixedly connected to the bottom of the upper exit of the escalator and the stairs; the support platform can be constructed in various ways such as precast reinforced concrete or welded steel frame. The horizontal position of the support platform can be flexibly arranged according to the layout requirements of the building functions. For example, the columns of the support platform can be hidden in the surrounding building walls to achieve a better building space and effect.

[0016] Step 3: According to the length, slope, and span of the escalator and the stairs, determine whether an auxiliary support platform needs to be added at the bottom of the escalator and the stairs, and if so, determine the quantity, position, size, and material of the auxiliary support platform.

[0017] Step 4: Construct the support platform and the auxiliary support platform according to the results determined in Steps 2 and 3.

[0018] Step 5: Install the escalator support pier and the stair support pier on the top of the support platform.

[0019] Step 6: Construct or place the escalator and the stairs so that the bottom of the lower exit of the escalator and the stairs jointly sits on the ground of the lower non-seismic isolation layer, and the bottom of the upper exit of the escalator and the stairs respectively sits on the escalator support pier and the stair support pier, and ensure that there is a seismic isolation joint reserved at the docking place between the upper exit of the escalator and the stairs and the upper seismic isolation layer; the stairs can be precast on-site with reinforced concrete or installed on-site with a steel structure staircase, and the escalator can be directly installed and placed on-site.

[0020] Step 7: Lap the sliding cover plate at the docking place between the upper exit of the escalator and the stairs and the upper seismic isolation layer to complete the docking between the escalator, the stairs and the upper seismic isolation layer.

[0021] Preferably, after the completion of Step 6, if there is an auxiliary support platform, support the auxiliary support platform at the bottom of the escalator and staircase; first install and place the escalator and staircase at the support platform, and then support the auxiliary support platform at the bottom of the escalator and staircase after the installation at the support platform is completed. The support of the support platform is the main one, and the support of the auxiliary support platform is the secondary one.

[0022] More preferably, a flexible support is adopted between the auxiliary support platform and the bottom of the escalator and staircase; the flexible support facilitates placing the position of the escalator and staircase first, and then supporting the auxiliary support platform at the bottom of the escalator and staircase, and can effectively absorb the vibration of the escalator and staircase during use.

[0023] The beneficial effects of the present invention are:

[0024] In the present invention, a support platform is established on the non-seismic isolation layer, the escalator and staircase are jointly arranged on the support platform, and then the upper exit of the escalator and staircase is lapped with the seismic isolation layer through a sliding cover plate, canceling the horizontal seismic isolation joint of the staircase, keeping the structure of the staircase itself intact, reducing the design and construction difficulty when setting the horizontal joint. At the same time, the escalator, staircase, support platform and non-seismic isolation layer jointly form a stable right-angled triangle structure, making the deformable part of the staircase coincide with the deformable part of the escalator, avoiding the interference and conflict that are likely to occur between the deformable part of the staircase and the non-deformable part of the escalator under the action of an earthquake, and even the situation of mutual damage. Therefore, the structure of the escalator and staircase jointly crossing the seismic isolation layer of the present invention is safer and more reliable. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation mode

[0032] The following will clearly and completely describe the related technologies in the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0033] Refer to Figures 1 to 6 , a structure for an escalator and staircase to jointly pass through an isolation layer, comprising: an escalator 1, a staircase 2, an upper isolation layer 3, a lower non-isolation layer 4. The upper isolation layer 3 is connected to the lower non-isolation layer 4 through an isolation bearing 5. The upper exits of the escalator 1 and the staircase 2 are docked with the upper isolation layer 3, and the lower exits of the escalator 1 and the staircase 2 are docked with the lower non-isolation layer 4. The escalator 1 and the staircase 2 are arranged side by side, in the same direction and with the same slope. A support platform 6 rising from the ground is provided on the ground of the lower non-isolation layer 4. The bottoms of the upper exits of the escalator 1 and the staircase 2 are both located on the support platform 6. The escalator 1, the staircase 2, the lower non-isolation layer 4 and the support platform 6 together form a right triangle structure in the vertical plane. An isolation joint 7 is reserved horizontally between the upper exits of the escalator 1 and the staircase 2 and the upper isolation layer 3. The upper exits of the escalator 1 and the staircase 2 and the upper isolation layer 3 are overlapped through a sliding cover plate 8, and the sliding cover plate 8 spans and covers the isolation joint 7; the support platform 6 is in a "door" shape, a cross beam 9 is provided at the top of the support platform 6, and columns 10 are provided on the ground of the lower non-isolation layer 4 to support the bottom of the cross beam 9 from bottom to top; the upper exits of the escalator 1 and the staircase 2 are jointly supported by the support platform 6, so that the deformable parts of the staircase 2 and the escalator 1 are combined into one place, avoiding the interference and conflict that easily occur between the deformable parts of the staircase and the non-deformable parts of the escalator under the action of an earthquake.

[0034] Further, the cross beam 9 includes a horizontal straight cross beam and a stepped cross beam. The horizontal straight cross beam has good rigidity but is not conducive to adjusting the different support heights of the escalator 1 and the staircase 2, while the stepped cross beam makes it more convenient and fast to adjust the support height according to the needs of different support heights of the escalator 1 and the staircase 2.

[0035] Further, between the bottom surfaces of the upper exits of the escalator 1 and the staircase 2 and the upper surfaces of the cross beams 9, there are respectively provided an escalator support pier 11 and a staircase support pier 12; the escalator support pier 11 and the staircase support pier 12 can conveniently and quickly adjust the different heights of the support piers caused by the presence of a horizontal platform at the upper exit of the escalator 1 while there is often no horizontal platform at the upper exit of the staircase 2.

[0036] Furthermore, both the escalator support pier 11 and the staircase support pier 12 are made of elastic materials, and the support piers made of elastic materials can eliminate the mutual vibration influence between the escalator 1 and the staircase 2.

[0037] Further, on the ground of the lower non-seismic isolation layer 4, there is also provided an auxiliary support platform 13 rising from the ground. The auxiliary support platform 13 supports the bottoms of the escalator 1 and the staircase 2 from bottom to top, and the support points of the auxiliary support platform 13 are located between the upper and lower exits of the escalator 1 and the staircase 2; the auxiliary support platform 13 can provide better stability and reliability when the escalator 1 and the staircase 2 are relatively long.

[0038] Further, the width of the seismic isolation joint 7 is not less than 60 cm; the seismic isolation joint 7 can effectively prevent the upper exits of the escalator 1 and the staircase 2 from being squeezed against the building edge during an earthquake, causing damage to the building or the escalator 1 and the staircase 2.

[0039] Further, the sliding cover plate 8 is a slidable cover plate whose length can be telescoped along the pedestrian direction; the slidable cover plate can be telescoped along the pedestrian direction. Therefore, in the case of a small horizontal displacement caused by a minor earthquake, it does not affect the lapping of the sliding cover plate 8. In addition, the sliding cover plate 8 can not only meet the requirement of the floor surface being flat during normal use, but also meet the requirement that when an earthquake comes, the seismic isolation joint 7 and the cover plate can deform freely enough without structural or equipment damage.

[0040] The present invention also discloses a method for the escalator and staircase to jointly pass through the seismic isolation layer. The method adopts the seismic isolation layer crossing structure of any one of the above claims, and the method includes the following steps:

[0041] Step 1: According to actual needs, determine the common upper exit positions of the escalator 1 and the staircase 2 at the upper seismic isolation layer 3 and the common lower exit positions at the lower non-seismic isolation layer 4; after determining the positions, preprocess the upper and lower exit positions of the upper seismic isolation layer 3 and the lower non-seismic isolation layer 4.

[0042] Step 2: Determine the horizontal position, vertical support height, size, and material of the support platform 6 fixedly connected to the bottom of the upper exits of the escalator 1 and the staircase 2 according to the lifting height, inclination angle, and step width of the escalator 1 and the staircase 2; The support platform 6 can be constructed in various ways such as precast reinforced concrete or welded steel frame. The horizontal position of the support platform 6 can be flexibly arranged according to the layout requirements of the building functions. For example, the columns 10 of the support platform 6 can be hidden in the surrounding building walls to achieve a better building space and effect;

[0043] Step 3: Determine whether auxiliary support platforms 13 need to be added to the bottom of the escalator 1 and the staircase 2 according to the length, slope, and span of the escalator 1 and the staircase 2, and the quantity, position, size, and material of the auxiliary support platforms 13 if needed;

[0044] Step 4: Construct the support platform 6 and the auxiliary support platforms 13 according to the results determined in Steps 2 and 3;

[0045] Step 5: Install the escalator support piers 11 and the staircase support piers 12 on the top of the support platform 6;

[0046] Step 6: Construct or place the escalator 1 and the staircase 2 so that the bottom of the lower exits of the escalator 1 and the staircase 2 are jointly located on the ground of the lower non-isolated layer 4, and the bottom of the upper exits of the escalator 1 and the staircase 2 are respectively located on the escalator support piers 11 and the staircase support piers 12, and ensure that there is an isolation joint 7 reserved at the interface between the upper exits of the escalator 1 and the staircase 2 and the upper isolated layer 3; The staircase 2 can be precast on-site with reinforced concrete or installed on-site with a steel structure staircase, and the escalator 1 can be directly installed and placed on-site;

[0047] Step 7: Overlap the sliding cover plate 8 at the interface between the upper exits of the escalator 1 and the staircase 2 and the upper isolated layer 3 to complete the connection between the escalator 1 and the staircase 2 and the upper isolated layer 3.

[0048] Further, after Step 6 is completed, if there are auxiliary support platforms 13, support the auxiliary support platforms 13 at the bottom of the escalator 1 and the staircase 2; First install and place the escalator 1 and the staircase 2 at the support platform 6, and then support the auxiliary support platforms 13 to the bottom of the escalator 1 and the staircase 2 after the installation at the support platform 6 is completed, with the support of the support platform 6 as the main and the support of the auxiliary support platforms 13 as the auxiliary.

[0049] Furthermore, a flexible support is adopted between the auxiliary support platforms 13 and the bottoms of the escalator 1 and the staircase 2; The flexible support facilitates placing the positions of the escalator 1 and the staircase 2 first and then supporting the auxiliary support platforms 13 to the bottoms of the escalator 1 and the staircase 2, and can effectively absorb the vibration of the escalator 1 and the staircase 2 during use.

[0050] Embodiment

[0051] In this embodiment, a lower non-isolated layer 4 is arranged in the underground foundation part of the airport, and an upper isolated layer 3 is arranged in the upper terminal building part. Escalators 1 and stairs 2 are installed side by side, in the same direction and with the same slope from the underground part to the upper terminal building part of the airport. A support platform 6 rising from the ground is arranged at the lower non-isolated layer 4, and the bottoms of the upper exits of the escalators 1 and stairs 2 are supported by the support platform 6. Escalator support piers 11 and stair support piers 12 made of elastic materials are arranged between the bottoms of the upper exits of the escalators 1 and stairs 2 and the support platform 6. The horizontal parts of the upper exits of the upper isolated layer 3 and the escalators 1 and stairs 2 are slidably overlapped by a sliding cover plate 8, facilitating pedestrians to enter and exit the upper exits of the escalators 1 and stairs 2.

[0052] During the seismic displacement test to simulate an earthquake, it is simulated that the upper isolated layer 3 of the upper terminal building part generates a large horizontal displacement relative to the lower non-isolated layer 4, and the escalators 1 and stairs 2 jointly generate horizontal displacement following the lower non-isolated layer 4, avoiding the interference and conflict that easily occur between the deformable parts of the stairs 2 and the non-deformable parts of the escalators 1 under the action of an earthquake, and even the situation of mutual damage, ensuring the safety of the escalators 1, stairs 2 and the building when passing through the isolated layer during an earthquake.

[0053] In summary, the present invention provides a structure and method for the combined crossing of an escalator and stairs through an isolated layer. By setting up a support platform on the non-isolated layer, arranging the escalator and stairs on the support platform together, and then overlapping the upper exits of the escalator and stairs with the isolated layer through a sliding cover plate, the horizontal isolation joint of the stairs is cancelled, keeping the structure of the stairs intact, reducing the design and construction difficulties when setting the horizontal joint. At the same time, the escalator, stairs, support platform and non-isolated layer jointly form a stable right triangle structure, combining the deformable parts of the stairs and the deformable parts of the escalator into one place, avoiding the interference and conflict that easily occur between the deformable parts of the stairs and the non-deformable parts of the escalator under the action of an earthquake, and even the situation of mutual damage, making the structure of the combined crossing of the escalator and stairs through the isolated layer safer and more reliable. Therefore, the present invention has a wide application prospect.

[0054] It should be emphasized that: the above are only the preferred embodiments of the present invention, and do not impose any form of limitation on the present invention. Any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
