Description

Technical Field

[0001] The invention relates to the technical field of building exterior walls, and in particular to a wind-vibration-resistant building exterior wall capable of recovering deformation and an installation method and system. Background Art

[0002] Wind load has a significant impact on building structures. As building height increases, the impact of wind load on high-rise or super-high-rise buildings becomes more and more significant. Wind load has a greater impact on building exterior wall components. Excessive wind load may cause the building exterior wall to fall off or break.

[0003] The exterior wall panels arranged parallel to the building exterior wall are often used as the maintenance of the building exterior wall and the first wind-resistant structure because they are convenient for the layout of the building exterior facade, and the exterior wall panels are easy to connect and seal. At the same time, they also have the effect of reflecting the beauty of the exterior facade. Although the combination of building exterior wall panels and building exterior walls can take into account the effects of building beauty, external protection, and wind resistance, if the building exterior wall is damaged under the influence of large wind loads, it is necessary to replace the building or reinforce the building exterior wall.

[0004] The self-resetting function is a new type of structural technology, which is mainly used in the field of building structure technology. The structure or component with this function can reset itself after being acted upon by external force, and can quickly restore the use function of the building component without maintenance or replacement. At present, there are few related technical applications of the self-resetting function in the field of building exterior walls. Summary of the invention

[0005] In view of the problems existing in the prior art, the present invention provides a wind-vibration-resistant building exterior wall capable of recovering deformation and an installation method and system.

[0006] The present invention is achieved through the following technical solutions:

[0008] Preferably, the rotating connector is provided in plurality, the plurality of vertical series rods are arranged in parallel, the plurality of vertical series rods form a whole through horizontal series rods, and the rotation reset device is connected to one of the vertical series rods.

[0009] Preferably, the rotary reset device is connected to one of the vertical series rods via a transmission belt.

[0010] Preferably, a top cap is provided between the vertical series rod and the horizontal series rod, and the transmission belt is sleeved between the rotational reset device and the top cap; a connecting platform and a bearing connecting section are also provided on the top cap, the connecting platform is arranged between the top cap and the bearing connecting section, and the bearing connecting section is rotationally connected to the horizontal series rod.

[0011] Preferably, a plurality of fixing blocks are provided between each of the vertical series rods and the outer wall, and the vertical series rods sequentially penetrate the plurality of fixing blocks and are rotatably connected to the fixing blocks.

[0012] Preferably, one end of the transmission rod away from the vertical series rod is provided with a rotatably connected slider, and the wall panel is provided with a slide rail, and the slider slides along the length direction of the slide rail.

[0013] Preferably, the slide rail is provided with a guide rail groove, and the slider is embedded in the guide rail groove.

[0014] Preferably, the transmission rod is arranged at an angle.

[0015] A method for installing a wind-vibration-resistant building exterior wall capable of recovering deformation, using the wind-vibration-resistant building exterior wall capable of recovering deformation, comprises the following steps:

[0016] S1, connect the vertical tandem rod with the transmission rod;

[0017] S2, connecting the transmission rod to the wall panel, and connecting the wall panel to the outer wall using a linear guide rail;

[0018] S3, connecting the vertical series rod and the rotation reset device.

[0019] A recoverable and wind-vibration-resistant building exterior wall system adopts a recoverable and wind-vibration-resistant building exterior wall, including symmetrically arranged recoverable and wind-vibration-resistant building exterior walls, and replaces a rotational reset device with a self-reset device, wherein the self-reset device is arranged between the rotating connectors of the recoverable and wind-vibration-resistant building exterior walls on both sides of the symmetry axis.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] The wind-vibration-resistant building exterior wall capable of recovering deformation can not only realize the connection between the exterior wall and the wallboard by arranging a rotating connector, but also realize the wind-vibration resistance and deformation recovery of the building exterior wall by cooperating with a rotating reset device.

[0022] The function of the linear guide is to ensure that the wall panels and the outer wall can only move in a direction perpendicular to the outer wall, while ensuring that the wall panels will not fall.

[0023] Furthermore, the function of the horizontal series rod is to connect all the vertical series rods in series to ensure that the rotation amplitudes of all the vertical series rods are the same, so that the rotation angles of all the vertical series rods can be the same. Finally, the movement trend of the horizontal series rods is only translational without rotation, so that all the vertical columns of exterior wall units in the exterior wall connection system of the present invention have the same movement trend, and no gaps will be generated between adjacent columns of exterior wall units.

[0024] Furthermore, when the wall panel approaches the outer wall under the action of wind load, multiple vertical series rods rotate and drive the transmission belt to move. The rotational reset device has the function of hindering the movement of the transmission belt, thereby hindering the movement of the wall panel through the vertical series rods connected to the rotational reset device, thereby realizing the reset of the wall panel.

[0025] Furthermore, the function of the fixing block is to fix the vertical series rod to the outer wall, and the vertical series rod and the fixing block are transitionally connected by a bearing to ensure that the vertical series rod can rotate inside the fixing block.

[0026] Furthermore, the transmission rod is tilted so that the projection of the fixed block on the wall panel does not overlap with the sliding block, thereby ensuring that when the wall panel and the outer wall are close to each other, the sliding block can slide in the sliding rail groove over a maximum displacement distance, thereby maximizing the relative displacement between the wall panel and the outer wall.

[0027] The present invention discloses a wind-vibration-resistant building exterior wall system capable of recovering deformation, in which a self-resetting device is used instead of a rotational resetting device. When wind load acts on the wall panels, the wall panels on both sides of the symmetry axis tend to approach the exterior wall, and the rotational connectors on both sides of the symmetry axis rotate in opposite directions. Due to the obstruction of the self-resetting device, the rotational tendency of the rotational connector is obstructed, thereby enabling the wall panels to recover deformation.

DETAILED DESCRIPTION

[0042] The present invention is further described in detail below in conjunction with specific embodiments, which are intended to explain the present invention rather than to limit it.

[0043] The present invention discloses a wind-vibration-resistant building exterior wall connection system capable of recovering deformation. Figure 1 , 2, 3, comprising a wall panel 1, an outer wall 2, a rotation reset device 9 and a rotation connector 4, wherein the wall panel 1 and the outer wall 2 are evenly arranged in blocks, that is, the wall panel 1 comprises a plurality of wall panel 1 units, and the outer wall 2 comprises a plurality of outer wall units. The rotation reset device 9 is rotationally connected to the rotation connector 4.

[0044] Reference Figure 4 , 5 , 6, the rotating connecting body 4 includes a vertical series rod 41 and a plurality of transmission rods 44, the vertical series rod 41 is rotationally connected to the outer wall 2, one end of the plurality of transmission rods 44 is fixedly connected to the vertical series rod 41, and the other end is slidably connected to the wall panel 1.

[0045] The rotating connecting body 4 is provided with a plurality of Fig.10 , multiple vertical series rods 41 are arranged in parallel, and multiple vertical series rods 41 form a whole through horizontal series rods 6, and the rotation reset device 9 is connected to one of the vertical series rods 41 through a transmission belt 8. In this embodiment, the transmission belt 8 is a chain or a belt.

[0046] The function of the horizontal series rod 6 is to connect all the vertical series rods 41 in series, and ensure that the rotation amplitudes of all the vertical series rods 41 are the same. When the rotation reset device 9 drives the vertical series rods 41 connected thereto to rotate, the remaining vertical series rods 41 will rotate synchronously under the action of the horizontal series rods 6. In this way, it can be ensured that the rotation angles of all the vertical series rods 41 are the same, and finally the movement trend of the horizontal series rods 6 is only translation without rotation, so that all the vertical columns of the exterior wall units in the exterior wall connection system of the present invention have the same movement trend, and there will be no gaps between adjacent columns of exterior wall units.

[0047] Reference Fig.10 , 11 A top cap 7 is provided between the vertical series rod 41 and the horizontal series rod 6, and a transmission belt 8 is sleeved between the rotation reset device 9 and the top cap 7. The top cap 7 is also provided with an integrally formed connection platform 71 and a bearing connection section 72. The connection platform 71 is provided between the top cap 7 and the bearing connection section 72, and the bearing connection section 72 is rotationally connected to the horizontal series rod 6. The bearing connection section 72 is for facilitating the connection between the connection platform 71 and the series bearing 61 in the horizontal series rod 6. During installation, the extension directions of all the connection platforms 71 are parallel, which is to ensure that the horizontal series rod 6 only produces a translational tendency.

[0048] In this embodiment, the connecting platform 71 is a cam-shaped structure, and the cross-sectional dimensions of all connecting platforms 71 are the same. The positioning and installation dimensions of all bearing connecting sections 72 on the connecting platform 71 are also the same. This is to ensure that the horizontal series rod 6 only moves in a translational manner.

[0049] The bottom elevation of the top cap 7 is greater than the building roof elevation, which is to ensure that the horizontal series rods 6 will not collide with the outer wall 2 during translation.

[0050] Reference Figure 5 A plurality of fixing blocks 42 are provided between each vertical series rod 41 and the outer wall 2 . The vertical series rods 41 pass through the plurality of fixing blocks 42 in sequence and are rotatably connected to the fixing blocks 42 .

[0051] Since the exterior wall units in the same vertical row share a vertical series rod 41, as long as the vertical series rod 41 rotates, it will drive all the transmission rods 44 connected to the vertical series rod 41 to rotate at the same time, and the rotation of the transmission rod 44 will cause the slider 52 to drive all the wall panels 1 to have the same displacement trend, so the wall panels 1 in the same vertical row in the building exterior wall connection system of the present invention will have the same displacement trend at the same time. When the wall panels 1 in the same vertical row produce a motion trajectory perpendicular to the exterior wall 2 and toward the exterior wall 2 under the action of wind load, the wall panels 1 in the same vertical row can be displaced synchronously, and no gaps will be generated between the wall panels 1 in the same vertical row, preventing rainwater from entering and destroying the sealing and thermal insulation performance of the building.

[0052] Reference Fig.11 , the rotation reset device 9 is arranged on the roof panel 10, and the vertical series rod 41 and the horizontal series rod 6 are both close to the outer wall 2, which is convenient for the staff to inspect and repair later. In this embodiment, the rotation reset device 9 is a plane scroll spring and a transmission disk, and the transmission disk is rotatably arranged on the roof panel 10 through a fixed shaft, one end of the plane scroll spring is fixedly connected to the fixed shaft, and the other end is connected to the transmission disk, and the transmission belt 8 is wound around the transmission disk and the outer side of the connecting platform 71. When installed, the plane scroll spring is in a relaxed state.

[0053] The rotation reset device 9 can generate energy dissipation when the vertical series rod 41 rotates, and then restore the angular displacement of the vertical series rod 41 caused by the wind load. In the process of restoring the angular displacement of the vertical series rod 41, the horizontal series rod 6 will drive the angular displacement of the vertical series rods 41 in all vertical rows to restore, thereby restoring the displacement of all wall panels 1 in the building exterior wall connection system of the present invention.

[0054] One end of the transmission rod 44 is rotatably connected to the vertical series rod 41 through the connection block 43, and the other end is slidably connected to the wall panel 1. The transmission rod 44, the connection block 43 and the vertical series rod 41 can be integrally formed or connected later.

[0055] Reference Figure 5 , 6 The end of the transmission rod 44 away from the vertical series rod 41 is provided with a rotatably connected slider 52, and the inner side of the wall panel 1 close to the outer wall 2 is provided with a slide rail 51, and the slide rail 51 is provided with a guide rail groove, and the slider 52 is embedded in the guide rail groove and slides along the length direction of the slide rail 51. In this embodiment, the cross section of the slider 52 is trapezoidal, and the length of the lower bottom is greater than the length of the upper bottom, and the slide rail 51 and the slider 52 are matched.

[0056] When the opening of the guide rail groove along the length direction faces upward, the slide rail 51 is connected to the wall panel 1 through the L-shaped connecting piece 53 arranged below, and the L-shaped connecting piece 53 can support the slide rail 51. Figure 7 , 8 When the opening of the guide rail groove along the length direction faces the outer wall 2, there is no need to set the L-shaped connecting piece 53.

[0057] The fixed block 42 is arranged on one side of the outer wall 2, and the slider 52 at the other end of the transmission rod 44 is also arranged on the side where the fixed block 42 is located, but the slider 52 is closer to the center plane of the wall panel 1 than the fixed block 42. At the same time, in order to connect the slider 52 and the vertical series rod 41, the transmission rod 44 is arranged at an angle, so that the projection of the fixed block 42 on the wall panel 1 does not overlap with the slider 52, so as to ensure that when the wall panel 1 and the outer wall 2 approach each other, the slider 52 can slide in the guide groove The displacement distance is the maximum, thereby maximizing the displacement amount between the wall panel 1 and the outer wall 2 in the direction perpendicular to the outer wall 2.

[0058] Reference Figure 1 A plurality of linear guide rails 3 are also provided between the wall panel 1 and the outer wall 2. The linear guide rails 3 are telescopic structures, and the plurality of linear guide rails 3 are arranged in parallel. In this embodiment, the length direction of the linear guide rails 3 is perpendicular to the surface of the wall panel 1. The linear guide rails 3 include a first part and a second part. One end of the first part is connected to the building wall panel, and the other end is slidably connected to the second part. The end of the second part away from the first part is connected to the building wall. The linear guide rails 3 are to ensure that the wall panel 1 and the outer wall 2 can only have a relative translational movement trend, and at the same time ensure that the wall panel 1 will not fall.

[0059] When a large wind load acts on the wall panel 1, the wall panel 1 will rely on the linear guide rail 3 to generate a movement tendency perpendicular to the wall panel 1 and close to the outer wall 2, and the slider 52 will slide in the guide rail groove. When the slider 52 slides, it will drive the transmission rod 44 to rotate around the fixed block 42. In this embodiment, when the slider 52 slides, the transmission rod 44 rotates counterclockwise. At this time, the vertical series rod 41 fixedly connected to the transmission rod 44 will rotate in the fixed block 42.

[0060] The present invention also discloses a method for installing a wind-vibration-resistant building exterior wall capable of recovering deformation:

[0061] S1: Connect the vertical series rod 41 and the transmission rod 44;

[0062] First, connect the top cap 7, the connecting block 43 and the transmission rod 44 to the vertical series rod 41, and keep the projections of all the transmission rods 44 in the building height direction overlap;

[0063] S2: Connecting the transmission rod 44 to the wall panel 1;

[0064] S21, connecting the slide rail 51 of the built-in slider 52 to the wall panel 1 through the L-shaped connector 53;

[0065] S22, install the vertical series rod 41 and the fixing block 42 at one end of the building outer wall close to the wall panel 1, ensure that the positions of the transmission rods 44 in all vertical rows of outer wall units are parallel, and ensure that the extension directions of the connecting platforms 71 in all vertical upper end outer wall units are parallel;

[0066] S23, connecting the outer wall 2 and the wall panel 1 through the linear guide 3, and during the connection, the slider 52 and the transmission rod 44 should be rotatably connected at the same time;

[0067] During installation, it should be ensured that the end faces of all wall panels 1 are located in the same plane, so that the projections of all sliders 52 in the same vertical row in the building height direction overlap, thereby ensuring that there is no gap between all exterior wall units.

[0068] S24, using the horizontal series rod 6 to connect the bearing connection sections above all the connection platforms 71, ensuring that the length extension line of the horizontal series rod 6 is parallel to the outer wall 2;

[0069] S3: Connect the vertical series rod 41 and the rotation reset device 9;

[0070] S31, a rotation reset device 9 is arranged above the roof panel, and the rotation reset device 9 is connected to the top cap 7 via a transmission belt 8;

[0071] S4, treating the gaps between all the wall panels 1 with sealant to ensure that rainwater does not penetrate into the wall panels 1 when the building exterior wall connection system of the present invention is in normal use.

[0072] In the wind-vibration-resistant building exterior wall capable of recovering deformation of the present invention, all the wall panels 1 will simultaneously produce a displacement tendency, which can greatly reduce the influence of wind load on the building exterior wall. At the same time, there are no other fixed connections between adjacent wall panels 1, which is convenient for construction.

[0073] The present invention also discloses a wind-vibration-resistant building exterior wall system capable of recovering deformation, referring to Fig.12 , 13 , including a symmetrically arranged recoverable anti-wind vibration building outer wall, the rotation reset device 9 is replaced by a self-reset device 11, and the self-reset device 11 is arranged between the rotating connectors 4 of the recoverable anti-wind vibration building outer wall on both sides of the symmetry axis. In this embodiment, the self-reset device 11 is a self-reset damper.

[0074] The number of the rotating connectors 4 is an even number. When the number of the rotating connectors 4 is greater than two, adjacent rotating connectors 4 located on the same side of the symmetry axis are connected by a horizontal series rod 6 .

[0075] When wind load acts on the wall panel 1, the wall panels 1 on both sides of the symmetry axis tend to approach the outer wall 2, and the rotating connectors 4 on both sides of the symmetry axis rotate in opposite directions. Due to the hindering effect of the self-resetting device 11, the rotation tendency of the rotating connector 4 is hindered, thereby enabling the wall panel 1 to have the ability to restore deformation.

[0076] A method for installing a wind-vibration-resistant building exterior wall system capable of recovering deformation is provided. First, the wind-vibration-resistant building exterior wall capable of recovering deformation is installed, and then a self-resetting device 11 is used to connect the rotating connectors 4 on both sides of the symmetry axis.
