Description

Technical Field

[0001] The invention relates to the field of building exterior walls, in particular to wind-vibration-resistant building exterior walls for passive ultra-low energy consumption buildings and an installation method thereof. Background Art

[0002] For high-rise or super-high-rise passive ultra-low energy buildings, wind vibration has a significant impact on the structure and building exterior walls. Wind vibration may cause structural resonance and cause the building curtain wall to fall or break. The exterior walls of passive ultra-low energy buildings separate the indoor environment of the building from the outside world, and play an important role in the building's thermal insulation, heat insulation, wind and rain protection, and noise prevention. However, large reciprocating wind loads will damage the building's exterior insulation, exterior wall finishes, and shading systems of passive ultra-low energy buildings, making the insulation effect of passive ultra-low energy buildings worse, thereby reducing living comfort.

[0003] At present, the exterior walls of passive ultra-low energy buildings usually do not have the ability to resist wind vibration, especially the exterior walls of high-rise or super-high-rise passive ultra-low energy buildings have weak wind resistance. In addition, there are many exterior wall operation procedures for high-rise super-passive low energy buildings and super-high-rise passive ultra-low energy buildings, and wind loads will cause risks of high-altitude operations. Therefore, the exterior walls used in high-rise or super-high-rise passive ultra-low energy buildings have the disadvantage of inconvenient maintenance.

[0004] Therefore, it is necessary to propose a new type of building exterior wall that can reduce the impact of wind vibration on buildings, has good thermal insulation effects, and is easy to maintain, making it suitable for passive ultra-low energy consumption buildings. Summary of the invention

[0014] Preferably, both ends of the fixing member are provided with ear plates, and the ear plates are used for installing the fixing plate.

[0015] Preferably, at least one limiting plate is provided on the guide rail, and the limiting plate is located between the plate body and the partition plate.

[0017] Preferably, a detachable lightweight plugging object is provided on one side of the plate body and the second cylinder body close to the interior of the room.

[0018] Preferably, a plurality of pressure regulating holes are also provided at the top of the plate body.

[0020] A method for installing wind-vibration-resistant building exterior walls for passive ultra-low energy consumption buildings comprises the following steps:

[0022] S2, installing the plate at a predetermined position;

[0023] S3, connecting the decorative plate to the first voltage regulating assembly;

[0024] S4, connecting the damping element to the second voltage regulating assembly.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] The wind-vibration-resistant building exterior wall for a passive ultra-low energy building of the present invention achieves the purpose of wind-vibration resistance by providing a hollow plate body and a first pressure regulating assembly and a second pressure regulating assembly connected thereto. The hollow plate body is an indispensable component for exerting "recoverable deformation" and at the same time enables the building exterior wall to have a good thermal insulation effect. When encountering strong winds, the decorative panel will have a displacement tendency close to the surface of the panel body, and the first piston member will have a displacement tendency toward the inside of the panel body under the pushing action of the decorative panel, while driving the second piston member to have a displacement tendency away from the panel body, and the damping member will limit the displacement tendency generated by the second piston member and restore the displacement tendency, thereby realizing the deformation recovery of the building exterior wall.

[0027] Furthermore, the displacement change produced by all the first piston members is smaller than the displacement change of all the second piston members in order to ensure that the decorative plate can cause the maximum displacement of the second piston member with a smaller displacement change, thereby maximizing the energy dissipation effect of the damping member.

[0028] Furthermore, the slide rail not only serves to connect the decorative panel and the panel body, but also can guide and support the movement of the decorative panel.

[0029] Furthermore, the partition can not only serve as a support to form a slide rail structure with fixings and guide rails, but also other building insulation layers, fireproof layers, shading systems and other components with smaller loads can be optionally installed on the end surface of the partition close to the decorative panel to meet the functional requirements of passive ultra-low energy consumption buildings.

[0030] Furthermore, the ear plate is for facilitating the installation of the fixing parts.

[0031] Furthermore, the limiting plate can limit the maximum distance between the decorative plate and the plate body, so as to avoid the decorative plate falling off due to the excessive distance between the decorative plate and the plate body.

[0032] Furthermore, the damping member will limit the displacement trend generated by the second piston member and restore the displacement trend. The tension and compression energy dissipation damper not only has the function of dissipating energy, but also maintains the air pressure balance in the panel body under normal use of the building exterior wall, fixes the guide rail through atmospheric pressure, and further limits the position of the decorative panel.

[0033] Furthermore, the sealing member can ensure the sealing inside the plate body, and the detachability is for the convenience of inspecting the internal air pressure state of the plate body.

[0034] Furthermore, the pressure regulating hole is for facilitating the inspection and maintenance of the hollow plate in the building's exterior wall. If the pressure inside the plate becomes unbalanced after long-term use of the building's exterior wall, the staff can readjust the pressure inside the plate or conduct inspection and maintenance through the pressure regulating hole.

[0035] Furthermore, the removable seal can not only ensure the aesthetics of the building when it is in use, but also facilitate personnel to inspect the internal pressure of the panel. They only need to remove the seal, and after adjustment, install the seal back to the outer wall to achieve sealing.

[0036] The invention discloses an installation method for a wind-vibration-resistant building exterior wall for a passive ultra-low energy consumption building, which is simple to operate and helps to improve installation efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0046] 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.

[0047] The present invention discloses a wind-vibration-resistant building exterior wall for a passive ultra-low energy consumption building, referring to Figure 1 , including decorative panels 3 and a hollow board body 1 arranged in parallel, the partition 2 is arranged on the outdoor side of the board body 1 through multiple slide rails 4, and multiple first voltage regulating components 6 are arranged inside the board body 1. In this embodiment, four first voltage regulating components 6 are provided and arranged in a rectangular shape.

[0048] Reference Figure 2 , 3 The first pressure regulating assembly 6 includes a first cylinder 61 and a first piston member 62. The axis of the first cylinder 61 is perpendicular to the surface of the decorative panel 3. The first cylinder 61 is connected to the inside of the panel 1, and the first piston member 62 is connected to the decorative panel 3. When installed, the first piston member 62 is located on the side close to the decorative panel 3.

[0049] The slide rail 4 includes a fixing part 42 and a guide rail 41. The partition 2 is arranged between the plate body 1 and the decorative plate 3. The partition 2 is parallel to the decorative plate 3. The lower part of the partition 2 is fixedly connected to the building structure component or the building connecting part. The end surface of the partition 2 close to the decorative plate 3 can be selected to fit other building insulation layers, fireproof layers, shading systems and other components with smaller loads.

[0050] Reference Figure 5 The fixing member 42 is connected between the plate body 1 and the partition plate 2 through an ear plate 43 arranged at the end. The ear plate 43 is connected to the plate body 1 by sealing bolts or other sealing processes, and the ear plate 43 is connected to the partition plate 2 by bolts.

[0051] The axis of the length of the guide rail 41 is parallel to the axis of the first cylinder 61 , the guide rail 41 is coaxially arranged with the fixing member 42 , the guide rail 41 is slidably connected inside the fixing member 42 , one end of the guide rail 41 is connected to the first piston member 62 , and the other end is connected to the decorative panel 3 .

[0052] Reference Figure 5 At least one stop plate 44 is provided on the guide rail 41, and the stop plate 44 is located between the plate body 1 and the partition 2, and the stop plate 44 is parallel to the partition 2. A guide groove is provided on the fixing member 42 along its length axis, and the stop plate 44 passes through the guide groove and extends out of the fixing member 42. Under normal use, a certain gap should be left between the stop plate 44 and the partition 2 or the plate body 1.

[0053] Reference Figure 6 , 7 , a plurality of second pressure regulating assemblies 5 are arranged at intervals and in parallel at the top of the plate body 1. In the present embodiment, three second pressure regulating assemblies 5 are provided. The second pressure regulating assemblies 5 include a second piston member 52 and a second cylinder body 53 closed at one end. The first cylinder body 61 and the second cylinder body 53 are both cylindrical. The axis of the second cylinder body 53 is perpendicular to the axis of the first cylinder body 61. The second cylinder body 53 is connected with the inside of the plate body 1 through the connecting hole 8 opened on the plate body 1. When installed, the second piston member 52 is located on the side close to the plate body 1.

[0054] Reference Figure 8 A damping member is provided on the outer side of the second cylinder 53, and the damping member is used to limit the change of the relative position between the second piston member 52 and the plate body 1. The damping member includes a tension and compression energy dissipation damper 10 and a plurality of tension damping components 7. The tension and compression energy dissipation damper 10 is located at the end of the second cylinder 53 opposite to the plate body 1, and the tension and compression energy dissipation damper 10 is detachably connected to the outer plate 51.

[0055] Under normal use, in order to maintain a constant position of the decorative panel 3, the first voltage regulating component 6 and the second voltage regulating component 5 need to maintain a constant internal structure, and the tension-compression energy-absorbing damper 10 can ensure that the internal structure of the second voltage regulating component 5 is constant, and further ensure that the internal structure of the first voltage regulating component 6 is constant.

[0056] When the building exterior wall is subjected to strong wind or impact, if the tension and compression energy dissipation damper 10 fails, the decorative panel 3 is likely to have a displacement tendency away from the building structure. At this time, the limit plate 44 will provide a safe displacement limit to ensure that the limit plate 44 will not have an excessive displacement tendency. In summary, no matter what kind of displacement tendency the decorative panel 3 has in the present application, the tension and compression energy dissipation damper 10 can ensure that the decorative panel 3 quickly recovers its deformation, and the tension and compression energy dissipation damper 10 is important for maintaining the stability of the normal use state of the building exterior wall of the present application.

[0057] The tension damping component 7 is detachably connected between the outer plate 51 and the plate body 1, and the length axis of the tension damping component 7 is parallel to the axis of the second cylinder 53. One end of the tension damping component 7 is connected to the second piston member 52 through the outer plate 51, one end of the second piston member 52 passes through the second cylinder 53 and is connected to the outer plate 51, and the other end of the tension damping component 7 is connected to the plate body 1. In this embodiment, the tension damping component 7 is a shape memory alloy wire, a spring or a small energy dissipation damper. When the decorative panel 3 has a displacement tendency close to the building structure, the tension damping component 7 can assist the tension and compression energy dissipation damper 10 to quickly restore the deformation of the building wall panel of the present application.

[0058] A detachable light-weight sealing member is provided on the side of the plate body 1 and the second cylinder body 53 close to the room to prevent people from accidentally touching or interfering with the sealing of the plate body 1 .

[0059] A plurality of pressure regulating holes 9 are also provided at the top of the plate body 1 . In the present embodiment, two pressure regulating holes 9 are provided and are spaced apart from the connecting hole 8 . A detachable sealing member is provided at the pressure regulating holes 9 .

[0060] The wind-vibration-resistant building exterior wall for a passive ultra-low energy consumption building of the present invention achieves the purpose of wind-vibration resistance by providing a hollow plate body 1 and a first voltage regulating assembly 6 and a second voltage regulating assembly 5 connected thereto. The hollow plate body 1 is an indispensable component for exerting "recoverable deformation" and at the same time enables the building exterior wall to have a good thermal insulation effect.

[0061] When encountering strong winds, the decorative panel 3 will have a displacement tendency close to the surface of the panel body 1. The first piston member 62 will have a displacement tendency toward the inside of the panel body 1 under the push of the decorative panel 3, and at the same time drive the second piston member 52 to have a displacement tendency away from the panel body 1. The damping member will limit the displacement tendency of the second piston member 52 and restore the displacement tendency, thereby realizing the deformation recovery of the building exterior wall.

[0062] When the exterior wall of the building needs to be inspected, the indoor blocking material is removed, and the air pressure balance state in the plate body 1 is checked by corresponding instruments, and auxiliary judgment is made by the deformation state of the tension damping component 7 and the tension and compression energy dissipation damper 10. If adjustment and repair are required, it is only necessary to open the seal at the pressure regulating hole 9, use instruments to adjust the air pressure inside the plate body 1, and finally reseal the pressure regulating hole 9.

[0063] The present invention also discloses a method for installing wind-vibration-resistant building exterior walls for passive ultra-low energy consumption buildings, comprising the following steps:

[0064] S1, prefabricate various components in a factory and simultaneously connect the first voltage regulating assembly 6 and the second voltage regulating assembly 5;

[0065] S2, installing the plate body 1 at a predetermined position, and fixing the lower part of the plate body 1 to a building structural member or a building connecting member;

[0066] S3, connecting the decorative plate 3 to the first voltage regulating assembly 6, including the following steps:

[0067] S31, the plate body 1 and the partition 2 are connected by a fixing member 42, and the lower part of the partition 2 is fixedly connected to a building structural member or a building connecting member;

[0068] S32, installing the guide rail 41;

[0069] S33, installing the decorative panel 3 and the guide rail 41;

[0070] S34, adjusting the position of the decorative panel 3, and then temporarily fixing the decorative panel 3 using a tool or an instrument;

[0071] S4, connecting the damping element to the second voltage regulating assembly 5, comprising the following steps;

[0072] S41, installing the tension damping component 7;

[0073] S42, the tension and compression energy dissipation damper 10 is installed between the outer plate 51 and the building structural component or the building connecting member;

[0074] S5, using a pressure regulating device to evacuate the air in the plate body 1 through the pressure regulating hole 9;

[0075] S6, using a detachable seal to seal the pressure regulating hole 9, and then removing the temporary fixation in S5.

[0076] Preferably, during the installation of the first voltage regulating assembly 6 in S1, the guide rail 41 should be connected at the same time to ensure the air tightness of the board 1. In order to ensure that the decorative board 3 can undergo a large wind vibration deformation, the structural length of the slide rail 4 needs to be adapted, but the pre-installed slide rail 4 will make it inconvenient to transport the board 1, because the external force interference on the slide rail 4 during transportation may destroy the air tightness of the board 1. Therefore, a section of the guide rail 41 can be set in S1, and a conversion connection port can be set to facilitate the extension and connection of the guide rail 41 in S3.

[0077] The plate body 1 is a hollow structure. The vacuum inside the plate body 1 can increase the thermal insulation effect of the building. In addition, the anti-wind vibration effect of the building exterior wall is achieved based on the fact that the plate body 1 is a closed structure. Therefore, during the construction process, the connection ports between the plate body 1 and other components also need to be processed using a sealing process.

[0078] In addition, the end surface of the plate body 1 close to the interior can also be selected to be fitted with other building insulation layers and fireproof layers according to the requirements of ultra-low energy consumption buildings.
