Description

Technical Field

[0001] This invention relates to the field of energy-saving glass curtain wall installation technology, specifically a prefabricated energy-saving viewing wall for sunken plazas. Background Technology

[0002] Sunken plazas, as an important spatial form in modern urban architecture, are widely used in commercial complexes, transportation hubs, and public landscape projects due to their unique sense of spatial hierarchy and harmony with the surrounding environment. To meet the requirements of lighting, visual transparency, and aesthetics, sunken plazas typically employ large-area glass curtain walls as their enclosure structure. However, traditional glass curtain walls have significant shortcomings in energy efficiency, leading to increased building energy consumption, specifically manifested in poor thermal insulation and low utilization of natural light.

[0003] In recent years, energy-saving glass curtain walls (such as Low-E coated glass, insulated glass filled with inert gas, and photovoltaic integrated glass) have gradually become the preferred solution for sunken plaza curtain walls due to their excellent thermal insulation performance and light regulation capabilities. These curtain walls not only effectively reduce summer air conditioning load and winter heating energy consumption, but also optimize indoor lighting through intelligent dimming technology, reducing reliance on artificial lighting and thus significantly improving the building's energy efficiency. Since sunken plaza curtain walls are typically large, clamping and hanging installation methods are often used to ensure the structure can withstand significant loads, meet safety and installation requirements, and avoid damaging the interlayer of the energy-saving glass curtain wall (such as the interlayer of laminated glass).

[0004] In practical use, the thermal expansion and contraction of glass curtain walls due to temperature changes can cause variations in the clamping force of the hanging clamps at the glass curtain wall connection points. This is especially true for energy-saving glass curtain walls, which typically have an interlayer of laminated glass or an air-filled cavity, and generally contain two or more layers of glass. This results in more significant variations in overall thickness compared to ordinary glass curtain walls. Traditional glass curtain wall hanging clamps cannot adjust for the stress changes at the clamping points caused by thermal expansion and contraction, particularly in areas with large diurnal temperature variations or significant seasonal temperature differences. When temperatures change, such as with triple-glazed, double-laminated energy-saving glass, thermal expansion can lead to excessive clamping force on the curtain wall, causing prolonged stress concentration at the clamping points. This can damage the laminated layer, allowing moisture from the air to enter and form bubbles, affecting energy efficiency and potentially damaging the glass surface. Conversely, cooling contraction can result in insufficient clamping force. Given the significant weight of the energy-saving curtain wall glass, this can lead to unstable clamping and structural loosening, affecting not only the energy-saving performance of the curtain wall but also posing safety hazards.

[0005] To address this, a prefabricated energy-saving viewing wall for sunken plazas is proposed. Summary of the Invention

[0006] The purpose of this invention is to provide a prefabricated energy-saving viewing wall for sunken plazas. This addresses the problem in existing technologies where traditional glass curtain wall clamps cannot adjust their clamping force to accommodate changes in thickness due to thermal expansion and contraction of the curtain wall glass. This is particularly relevant for heavier, thicker energy-saving curtain wall glass, where excessive clamping can damage the interlayer of the glass, while insufficient clamping can lead to instability and safety hazards.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A prefabricated energy-saving viewing wall for sunken plazas includes a curtain wall, a shell, a suspension rod, grippers, clamping components, clamps, limiting components, magnifying components, trigger columns, shrinkage adjustment components, and expansion adjustment components. Friction blocks are provided at both the front and rear ends of the curtain wall. The shell and suspension rods are sequentially connected to the upper part of the curtain wall from bottom to top. The grippers are located at both the front and rear ends of the shell, with two sets of grippers on each end of the shell. The clamps are slidably connected to the grippers. The limiting components are connected between the clamps and the grippers, and are used to ensure that the clamps are clamped tightly against the friction blocks to a certain force before releasing the grippers. The trigger post is fixed and connected between the two jaws of each end housing. The amplification component is disposed on the jaws and is used to drive the trigger post to move left and right after the relative displacement between the clamp and the jaws. The shrinkage adjustment component is disposed at the left end of the trigger post. When the curtain wall shrinks due to cold, it works with the amplification component to move the trigger post to the left and unlock the jaws to increase the clamping force of the clamp on the curtain wall in conjunction with the weight of the curtain wall. The expansion adjustment component is disposed at the right end of the trigger post. When the curtain wall expands due to heat, it works with the amplification component to move the trigger post to the right and spread the jaws to reduce the clamping force of the clamp on the curtain wall.

[0009] Preferably, the curtain wall is made of triple-glazed, double-laminated glass, and the friction block is composed of epoxy resin adhesive, non-woven fabric and copper sheet. The epoxy resin adhesive, non-woven fabric and copper sheet are sequentially adhered to the front and rear ends of the curtain wall, and the clamp contacts the end of the copper sheet away from the curtain wall.

[0010] Preferably, the clamping component includes a clamping groove, a clamping gear, a central rack, a clamping limiting rod, an upper clamping rack, and a lower clamping rack. The clamping groove is formed inside the housing. The clamping gear is rotatably connected to the clamping groove. The clamping limiting rod and the central rack are fixedly connected to the front and rear ends of the suspension rod. The central rack meshes with the front end of the clamping gear. The upper and lower clamping racks are slidably connected to the upper and lower sides of the clamping gear, respectively. The upper and lower clamping racks mesh with the upper and lower ends of the clamping gear, respectively. The upper clamping rack is connected to the jaws at the front end of the curtain wall, and the lower clamping rack is connected to the jaws at the rear end of the curtain wall.

[0011] Preferably, the limiting component includes a connecting rod, a connecting spring, and a fixing unit. The fixing unit is used to fix the gripper. The connecting rod is slidably connected to the gripper. The side of the connecting rod near the curtain wall is fixedly connected to the clamp. The two ends of the connecting spring are respectively connected to the side of the clamp away from the curtain wall and the side of the connecting rod near the curtain wall.

[0012] Preferably, the fixing unit includes a limiting groove, a limiting spring, a limiting connecting plate, a limiting block, a limiting lock groove, a mounting lock block, and a mounting lock plate. The limiting groove has a clamping jaw at its left end and a corresponding upper or lower clamping rack. The limiting connecting plate is slidably connected within the limiting groove. The limiting connecting plate has a mounting lock block at its right end, and the mounting lock block has a mounting chamfer. The mounting lock plate is slidably connected to the clamping jaw and engages with the mounting chamfer. The limiting spring has two ends connected to the left end of the limiting connecting plate and the inner wall of the clamping jaw, respectively. The limiting lock groove is located within the housing. The limiting block is located at the right end of the upper and lower clamping racks on the left side and engages with the limiting lock groove.

[0013] Preferably, the amplifying component includes an amplifying wheel, an amplifying limiting rod, an amplifying limiting ring, and an amplifying pointer. The amplifying wheel is rotatably connected to the gripper, the lower end of the amplifying wheel is in contact with the upper end of the connecting rod, the amplifying limiting rod is fixedly connected to the amplifying wheel, the trigger post is slidably connected to the amplifying limiting rod in the left-right direction, the amplifying limiting ring is rotatably connected to the trigger post, the amplifying pointer is fixedly connected to the amplifying limiting ring, and the trigger post and the amplifying limiting ring are connected by a thread.

[0014] Preferably, the shrink adjustment component includes a shrink push rod and a movable groove. The shrink push rod is located at the right end of the limiting connecting plate, the movable groove is opened on the mounting lock plate, the magnifying pointer cooperates with the movable groove, and the left end of the trigger post cooperates with the shrink push rod.

[0015] Preferably, the expansion adjustment component includes an expansion push rod, an expansion groove, an expansion connecting plate, an expansion push block, an expansion friction ring, an expansion threaded column, an expansion threaded groove, a return spring, and a return ring. The expansion groove is formed in the upper or lower clamping rack at the right-side gripper and its corresponding position. The expansion connecting plate is slidably connected in the expansion groove. An expansion spring is provided between the right end of the expansion connecting plate and the inner wall of the right-side gripper. The expansion push rod is located at the left end of the expansion connecting plate. The right end of the trigger column cooperates with the expansion push rod. The expansion threaded groove is formed at the center of the right end of the clamping gear. The expansion threaded column is connected by a threaded... The expansion friction ring is connected within the expansion threaded groove and is mounted on the expansion threaded post. The expansion push block is mounted on the right end of the expansion connecting plate. A sliding groove is provided inside the expansion push block, and a sliding block is slidably connected within the sliding groove. A sliding spring is provided on the side of the sliding block away from the gripper. Both ends of the sliding spring abut against the inner walls of the sliding block and the expansion push block, respectively. The right end of the sliding block engages with the left end of the expansion friction ring. The reset ring is slidably connected within the housing, with its left end slidably connected to the right end of the expansion friction ring. One end of the reset spring is connected to the right end of the reset ring, and the other end abuts against the inner wall of the housing.

[0016] Preferably, the limiting block is provided with a limiting chamfer, which cooperates with the limiting locking groove.

[0017] Preferably, there are gaps between the left and right ends of the trigger post and the expansion push rod and the retraction push rod.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] By installing clamps and jaws on both sides of the curtain wall, the clamps hold the friction blocks on both sides of the curtain wall. The clamping component tightens the clamps to a suitable force and then stops. By installing trigger posts and amplification components, when the curtain wall contracts due to cooling, the contraction adjustment component, in conjunction with the trigger post, increases the clamping force of the clamps on the curtain wall. By installing expansion adjustment components, when the curtain wall expands due to heating, the trigger post, in conjunction with the expansion component, decreases the clamping force of the clamps on the curtain wall. This achieves automatic adjustment of the clamping force of the curtain wall glass, ensuring that the curtain wall glass is always maintained at a suitable clamping force. This prevents excessive clamping force from damaging the laminated layer, affecting energy-saving performance and aesthetics, while also preventing excessively loose clamping force, which could lead to unstable clamping and reduce safety hazards.

[0031] To ensure a clear and complete description of the technical solutions in the embodiments of the present invention, and to make the features and advantages more apparent and understandable, the specific implementation methods of the present invention will be described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0032] Example 1

[0033] Please see Figures 1 to 6 This invention provides a prefabricated energy-saving viewing wall for sunken plazas, comprising a curtain wall 1, a shell 2, a suspension rod 3, grippers 4, clamping components 5, clamps 6, limiting components 7, a magnifying component 8, a trigger column 9, a shrinkage adjustment component 10, and an expansion adjustment component 11. Friction blocks 12 are provided at both ends of the curtain wall 1. The shell 2 and the suspension rod 3 are connected sequentially from bottom to top to the upper end of the curtain wall 1. The upper end of the suspension rod 3 is fixedly connected to the load-bearing body. Grippers 4 are provided at both ends of the shell 2, with two sets of grippers 4 provided on each end of the shell 2. Clamps 6 are slidably connected to the grippers 4. The limiting component 7 is connected between the clamps 6 and the grippers 4, and is used to clamp the clamps 6 and the friction blocks 12 tightly. After a certain force is applied, the jaws 4 are fixed. The trigger post 9 is connected between the two jaws 4 of each end of the housing 2. The amplification component 8 is set on the jaws 4. It is used to drive the trigger post 9 to move left and right after the relative displacement between the chuck 6 and the jaws 4. The shrinkage adjustment component 10 is set on the left end of the trigger post 9. When the curtain wall 1 shrinks due to cold, it works with the amplification component 8 to move the trigger post 9 to the left and unlock the jaws 4 to increase the clamping force of the chuck 6 on the curtain wall 1 in conjunction with the weight of the curtain wall 1. The expansion adjustment component 11 is set on the right end of the trigger post 9. When the curtain wall 1 expands due to heat, it works with the amplification component 8 to move the trigger post 9 to the right and open the jaws 4 to reduce the clamping force of the chuck 6 on the curtain wall 1.

[0034] Specifically, Curtain Wall 1 is made of triple-glazed, double-laminated glass, consisting of three panes of glass and two interlayers of interlayer adhesive. Using this energy-saving triple-glazed, double-laminated glass as the viewing wall for the sunken plaza provides superior safety and impact resistance. The triple-glazed structure can withstand wind pressure from the surrounding area and accidental impacts (such as mechanical collisions), making it far safer than ordinary glass. It also offers excellent sound insulation and noise reduction, which is especially important in a high-traffic sunken plaza. Furthermore, the use of ultra-clear glass substrate achieves over 90% light transmittance, reducing the feeling of confinement in the underground space and enhancing natural lighting. The interlayer adhesive... It can filter 99% of ultraviolet rays, protecting the decorations in the sunken plaza from fading, extending their service life, and has a good energy-saving effect. The friction block 12 is composed of epoxy resin, non-woven fabric, and copper sheet. The epoxy resin, non-woven fabric, and copper sheet are sequentially adhered to the front and rear ends of the curtain wall 1. A groove is left in the middle of the end of the copper sheet away from the curtain wall 1. When the glass curtain wall 1 is suspended, the clamp 6 contacts and engages with the groove at the end of the copper sheet away from the curtain wall 1, increasing the friction and engagement performance at the contact point between the clamp 6 and the copper sheet. This prevents the curtain wall 1 from having a much higher overall quality than ordinary glass due to the use of triple-glazed double-cavity glass, which would lead to insufficient friction between the clamp 6 and the friction block 12, resulting in loosening.

[0035] The clamping component 5 includes a clamping groove 51, a clamping gear 52, a central rack 53, a clamping limit rod 54, an upper clamping rack 55, and a lower clamping rack 56. The curtain wall 1 has two sets of jaws 4 at its front and rear ends, each jaw 4 corresponding to either an upper clamping rack 55 or a lower clamping rack 56. In this attached diagram, the upper clamping rack 55 is connected to the jaw 4 at the front end of the curtain wall 1, and the lower clamping rack 56 is connected to the jaw 4 at the rear end of the curtain wall 1. The specific installation can be adjusted according to the mating position of the central rack 53 and the clamping gear 52. 51 is opened inside the housing 2. The clamping gear 52 is rotatably connected in the clamping groove 51. The clamping limit rod 54 and the central rack 53 are respectively fixedly connected to the front and rear ends of the hanging rod 3. The central rack 53 meshes with the front end of the clamping gear 52. The upper clamping rack 55 and the lower clamping rack 56 are respectively slidably connected to the upper and lower sides of the clamping gear 52. The upper clamping rack 55 and the clamping rack mesh with the upper and lower ends of the clamping gear 52 respectively. The upper clamping rack 55 is connected to the claw 4 at the front end of the curtain wall 1, and the lower clamping rack 56 is connected to the claw 4 at the rear end of the curtain wall 1.

[0036] The triple-glazed, double-laminated energy-saving glass curtain wall 1 achieves numerous energy-saving effects. Furthermore, because the triple-glazed, double-laminated glass is heavier than that of a typical glass curtain wall 1, when the clamp 6 engages with the friction block 12, the curtain wall 1 provides sufficient weight to apply weight to the shell 2. This allows the shell 2, under the tension of the hanger 3 and the action of the clamping component 5, to convert the weight of the triple-glazed, double-laminated glass curtain wall 1 into clamping force, thus meeting the clamping force requirement of the clamp 6 on the glass curtain wall 1. By ensuring sufficient friction and engagement between the friction block 12 and the clamp 6, the excessively heavy glass curtain wall 1 can even provide an excess of weight to be converted into clamping force.

[0037] The limiting component 7 includes a connecting rod 71, a connecting spring 72, and a fixing unit 73. The fixing unit 73 is used to fix the clamp 4. The connecting rod 71 is slidably connected to the clamp 4. The side of the connecting rod 71 closest to the curtain wall 1 is fixedly connected to the clamp 6. The two ends of the connecting spring 72 are respectively connected to the side of the clamp 6 away from the curtain wall 1 and the side of the connecting rod 71 closest to the curtain wall 1. The connecting spring 72 is made of Invar alloy, which ensures that it will hardly be affected by thermal expansion and contraction deformation within the normal temperature range of -20 degrees Celsius to 80 degrees Celsius, thus ensuring the stability of the clamping force. The connecting rod 71 can be set with a scale to reflect the degree of compression of the connecting spring 72. The scale is not shown in the diagram. This accurately reflects the clamping force on the glass of the curtain wall 1, preventing the interlayer (such as PVB / SGP) from separating from the glass surface in the pressure concentration area due to excessive squeezing of the glass edge during lifting. This creates tiny gaps, causing the air or water vapor remaining in the gaps to expand and form visible bubbles.

[0038] The fixing unit 73 includes a limiting groove 731, a limiting spring 732, a limiting connecting plate 733, a limiting block 734, a limiting lock groove 735, a mounting lock block 736, and a mounting lock plate 737. The limiting groove 731 has a left-end clamping jaw 4 inside its corresponding upper clamping rack 55 or lower clamping rack 56. The limiting connecting plate 733 is slidably connected to the limiting groove 731. The right end of the limiting connecting plate 733 is provided with a mounting lock block 736, which has a mounting chamfer 7361. The mounting lock plate 737 is slidably connected to the clamping jaw 4. The mounting lock plate 737 cooperates with the mounting chamfer 7361. This cooperation means that when adjusting the clamping force of the clamp 6 on the glass curtain wall 1, the mounting lock plate 737 is first pushed upward. During the upward movement of the mounting lock plate 737, the mounting lock plate 737 will first come into contact with the mounting chamfer 7361. The limiting plate 733 is pushed to the left along the chamfer 7361 to compress the limiting spring 732. The limiting plate 733 moves to the left, causing the limiting block 734 to move to the left until the right end of the mounting lock block 736 is completely moved into the hole of the mounting lock plate 737. At this time, the limiting block 734 is completely pulled out of the limiting lock groove 735, so that the gripper 4 can remain unlocked when the position of the gripper 4 is adjusted. The two ends of the limiting spring 732 are connected to the left end of the limiting plate 733 and the inner wall of the gripper 4, respectively. The limiting lock groove 735 is opened in the housing 2. The limiting block 734 is set on the right end of the upper clamping rack 55 and the lower clamping rack 56 on the left side. The limiting block 734 cooperates with the limiting lock groove 735. The cooperation here means that when the limiting spring 732 is in the normal state, the limiting block 734 will be inserted into the limiting lock groove 735 under the action of the elastic force of the limiting spring 732.

[0039] When suspending the glass curtain wall 1, first fix the suspension rod 3 at the designated position, push the mounting lock plate 737 upward to the mounting lock block 736 position, restricting the connecting plate 733 to compress the restricting spring 732, and the restricting block 734 to pull out the restricting lock groove 735, thereby allowing the upper clamping rack 55 and the lower clamping rack 56 on the left side to slide back and forth within the housing 2. Then, move the curtain wall 1 below the suspension rod 3, pull the housing 2 downward as a whole, so that the clamps 6 on both sides move closer to the curtain wall 1 until the clamps 6 contact the copper sheet of the friction block 12. Then, slowly lower the curtain wall 1, so that the weight of the curtain wall 1 is gradually clamped and pulled by the suspension rod 3 and the clamps 6. During the slow lowering of the curtain wall 1, due to the engagement of the clamps 6 and the copper sheet, the curtain wall 1 will move. The chuck 6 and housing 2 move downward relative to the boom 3, causing the clamping gear 52 inside the housing 2 to move downward relative to the central rack 53 at the lower end of the boom 3. The clamping limit rod 54 limits the direction of the housing 2 and the boom 3. During the downward movement of the clamping gear 52 relative to the central gear, the clamping gear 52 rotates forward, causing the upper clamping rack 55 and lower clamping rack 56 on both sides to move closer to the center of the housing 2. This, in turn, causes the jaws 4 on both sides to move closer to the curtain wall 1. At this time, because the chuck 6 engages and abuts against the friction block 12 on the curtain wall 1, as the jaws 4 move closer to the curtain wall 1, they will press against the connecting spring 72, making the clamping force of the chuck 6 on the curtain wall 1 increasingly tighter. The clamping force is determined by reading the scale of the connecting rod 71 at the chuck 6. Once the appropriate clamping force for this type of glass curtain wall 1 is reached, the magnifying pointer 84 will be vertically upward. Release of the curtain wall 1 is then stopped. The mounting lock plate 737 is then moved downwards along the jaw 4, so that the movable groove 102 of the mounting lock plate 737 fits onto the magnifying pointer 84. The mounting lock plate 737 is fully moved to the lower end of the mounting lock block 736, causing the limiting connecting plate 733 to reset under the action of the limiting spring 732. This allows the limiting block 734 on the right end of the limiting connecting plate 733 to re-insert into the limiting lock groove 735, thus fixing the upper clamping rack 55 and the lower clamping rack 56 on the left end, thereby stopping the clamping process. As the housing 2 continues to move relative to the suspension rod 3, the clamp 4 stops moving closer to the curtain wall 1, maintaining the clamping force of the clamp 6 on the curtain wall 1 at a suitable level. This prevents the curtain wall 1 from becoming too heavy due to its large size, which would cause the clamp 6 to exert an excessive clamping force on the curtain wall 1. This is especially important when using heavier, more energy-efficient glass curtain walls 1, such as laminated glass or triple-glazed glass with two layers of adhesive, in sunken plazas. If the clamping force is too great, the suspension rod will excessively compress the upper edge of the glass, causing the laminated layer to separate from the edge and form tiny gaps. As the temperature rises and water vapor expands, visible bubbles will form inside the glass, affecting both the viewing effect and the energy efficiency, such as the ability of the adhesive to block ultraviolet rays.

[0040] Example 2

[0041] Please see Figures 4 to 9This invention provides a prefabricated energy-saving viewing wall for sunken plazas, including an amplifying component 8. The amplifying component 8 includes an amplifying wheel 81, an amplifying limiting rod 82, an amplifying limiting ring 83, and an amplifying pointer 84. The amplifying wheel 81 is rotatably connected to the gripper 4. The diameter of the amplifying wheel 81 is selected to be as small as possible. The friction force on the upper surfaces of the amplifying wheel 81 and the connecting rod 71 is sufficiently large to meet the high friction requirements between them. The purpose of the amplifying wheel 81 design is that even if the overall thickness of the curtain wall 1 and the friction block 12 changes slightly, causing the connecting rod 71 to only undergo a slight displacement, the amplifying wheel 81 can still rotate a certain angle under the contact friction between the amplifying wheel 81 and the connecting rod 71, thereby driving the movement of a series of components such as the amplifying limiting rod 82.

[0042] The lower end of the magnifying wheel 81 is attached to the upper end of the connecting rod 71. The magnifying limit rod 82 is fixedly connected to the magnifying wheel 81. The trigger post 9 is slidably connected to the magnifying limit rod 82 in the left and right direction. The magnifying limit ring 83 is rotatably connected to the trigger post 9. The magnifying pointer 84 is fixedly connected to the magnifying limit ring 83. The trigger post 9 and the magnifying limit ring 83 are connected by threads. Here, when the overall thickness of the curtain wall 1 in the middle of the clamp 6 changes, the clamp 6 will have a relative displacement with the fixed jaw 4, which will cause the connecting rod 71 to move relative to the jaw 4. The movement of the connecting rod 71 will drive the magnifying wheel 81 to rotate. Under the action of the magnifying limit rod 82, the magnifying wheel 81 will drive the trigger ring to rotate. At this time, since the trigger post 9 is threadedly connected to the magnifying limit ring 83, and the magnifying pointer 84 at the upper end of the magnifying limit ring 83 is limited by the movable groove 102 on the mounting lock plate 737, when the trigger post 9 rotates, the trigger post 9 can move back and forth along the threads under the limitation of the magnifying limit ring 83 and the magnifying limit rod 82.

[0043] When the glass in the curtain wall 1 is in use, especially in energy-saving glass curtain walls 1 such as triple-glazed glass with double-layer lamination or insulated glass with a relatively thick overall thickness, the glass, adhesive layer, insulated layer, and friction block 12 (epoxy resin adhesive, copper sheet, etc.) between the clamps 6 will experience thermal expansion and contraction when the temperature changes significantly. This causes changes in the overall thickness and length of the curtain wall 1 between the clamps 6. This is especially true for large sunken plaza viewing curtain walls 1, because the glass curtain wall 1 is large and heavy, and its edges are relatively brittle. Therefore, the curtain wall 1 is generally clamped and supported by hanging clamps, and a gap is left at the bottom of the curtain wall 1 to accommodate the longitudinal thermal expansion of the glass in the curtain wall 1. Due to thermal contraction, the bottom of curtain wall 1 does not serve as the primary support. Therefore, when the thickness changes, the clamping force of clamp 6 on curtain wall 1 will change. If it is too loose, the clamping effect will be poor, the bottom of curtain wall 1 will be under stress, and there is a risk of breakage. If it is too tight, it will cause over-clamping at the upper clamping point. When used as an energy-saving laminated glass curtain wall 1, air bubbles may be generated in the laminated layer. When the length changes, if the length increases, the bottom of curtain wall 1 will gradually be under stress. If the length decreases, it may cause the bottom of curtain wall 1 to separate from the reserved gap, causing the bottom of curtain wall 1 to lose its lateral limiting and fixing, and also affecting the sealing effect of the inside and outside of curtain wall 1.

[0044] The retraction adjustment component 10 includes a retraction push rod 101 and a movable groove 102. The retraction push rod 101 is located at the right end of the limiting connecting plate 733. The movable groove 102 is opened on the mounting lock plate 737. The magnifying pointer 84 cooperates with the movable groove 102. The cooperation here means that after the glass of the curtain wall 1 is installed, the connecting rod 71 displays a suitable clamping force, and the magnifying pointer 84 is in a vertical upward position. At this time, the mounting lock plate 737 is pressed down so that the movable groove 102 of the mounting lock plate 737 can just cover the magnifying pointer 84, thereby limiting the left and right ends of the magnifying pointer 84. The left and right ends of the trigger post 9 are left with gaps between the expansion push rod 111 and the retraction push rod 101. The purpose of this design is to ensure that the appropriate clamping force of the clamp 6 on the glass curtain wall 1 can be within a range. The gaps between the left and right ends of the trigger post 9 and the expansion push rod 111 and the retraction push rod 101 are to ensure that even if there is a slight change in thickness during the use of the curtain wall 1, as long as the clamping force of the clamp 6 on the curtain wall 1 is still within the appropriate range, when the clamp 6 is slightly displaced due to the thickness of the curtain wall 1, which in turn drives the magnifying wheel 81, the magnifying limit rod 82, and the adjusting post to rotate, the adjusting post will move left and right under the limit of the magnifying limit ring 83, the magnifying pointer 84, and the mounting lock plate 737, without contacting the expansion push rod 111 and the retraction push rod 101. This ensures that the clamp 6 is within the appropriate clamping force range, without frequent adjustments to the clamping force, reducing wear and extending the service life of the device.

[0045] The left end of the trigger post 9 engages with the retraction push rod 101. This engagement means that when the curtain wall 1 and the friction block 12 shrink to a certain extent due to cooling, the overall thickness of the curtain wall 1 will shrink. Since the gripper 4 and the housing 2 are in a fixed state, the two sides of the curtain wall 1 will move away from the gripper 4, causing the clamping force of the clamp 6 and the connecting spring 72 on the curtain wall 1 to decrease. During this process, the clamp 6 will be in contact with the friction block 12 on both sides of the curtain wall 1 under the action of the connecting spring 72, and will drive the connecting rod 71 to move closer to the curtain wall 1. When the connecting rod 71 moves, it will drive the amplifying wheel 81 to rotate in the forward direction. The rotation of the amplifying wheel 81 in the forward direction will drive the amplifying limit rod 82 and the trigger post 9 to rotate in the forward direction. Since the amplifying limit wheel and the amplifying pointer 84 are limited by the mounting locking plate 737, the adjusting post will slide to the left along the thread between it and the amplifying limit wheel on the amplifying limit rod 82 until the left end abuts against the retraction push rod 101 and pushes the retraction push rod 101 to the left.

[0046] The rest of the structure is the same as in Example 1.

[0047] After the glass curtain wall 1 is installed, when the ambient temperature is low, the overall thickness and length of the curtain wall 1 will be slightly reduced. When the thickness is reduced to a certain extent, the clamping force of the clamp 6 on the curtain wall 1 will be lower than the appropriate range. It is necessary to adjust the clamping force of the clamp 6 on the curtain wall 1 appropriately to prevent the clamping from being too loose, which would result in insufficient clamping force on the energy-saving laminated glass curtain wall 1 and the risk of falling. At the same time, after the overall length of the curtain wall 1 is reduced to a certain extent, it is also necessary to adjust the longitudinal position of the curtain wall 1 appropriately to prevent the bottom of the curtain wall 1 from separating from the reserved gap, so that the bottom of the curtain wall 1 loses its lateral restraint.

[0048] As the overall thickness of the curtain wall 1 decreases in the prefabricated energy-saving viewing wall of the sunken plaza of this application, the clamp 6, under the action of the connecting spring 72, comes into contact with the friction blocks 12 on both sides of the curtain wall 1, and drives the connecting rod 71 to move closer to the curtain wall 1. When the connecting rod 71 moves, it drives the amplifying wheel 81 to rotate in the forward direction. The rotation of the amplifying wheel 81 in the forward direction drives the amplifying limit rod 82 and the trigger post 9 to rotate in the forward direction. The adjusting post slides to the left along the thread on the amplifying limit rod 82. When the overall thickness of the curtain wall 1 decreases to a certain extent, the clamping force of the clamp 6 on the curtain wall 1 decreases to almost below the appropriate range. At this time, the left end of the trigger post 9 abuts against the retraction push rod 101 and pushes the retraction push rod 101 to the left. The retraction push rod 101 moves to the left, pushing the limiting plate 733 to move to the left and squeezing the limiting spring 732. At the same time, it drives the limiting block 734 on the limiting plate 733 to move to the left, so that the limiting block 734 disengages from the limiting lock groove 735, thereby causing the clamp to... 4. Unlocking is achieved between the curtain wall 1 and the housing 2. At this time, under the action of the gravity of the curtain wall 1 and the friction engagement between the friction block 12 of the curtain wall 1 and the clamp 6, the curtain wall 1 will drive the clamp 6, the jaw 4, and the housing 2 to move downward relative to the hanger 3. This causes the clamping gear 52 in the housing 2 to move downward relative to the central rack 53 below the hanger 3. The clamping gear 52 rotates forward under the action of the central rack 53, causing the upper clamping rack 55 and the lower clamping rack 56 on both sides to move further towards the center of the housing 2. This causes the jaws 4 on both sides to move closer to the curtain wall 1 and squeeze the connecting spring 72, increasing the clamping force of the clamp 6 on the curtain wall 1 until the clamping force of the clamp 6 on the curtain wall 1 returns to the normal clamping force range. During this process, the curtain wall 1 will also gradually descend, effectively preventing the curtain wall 1 from shrinking in length due to cold, preventing the bottom length of the curtain wall 1 from being insufficient and moving out of the reserved gap, resulting in loss of the lower limit, or reducing the sealing and heat preservation and energy-saving effect of the curtain wall 1.

[0049] As the gripper 4 moves closer to the curtain wall 1, the clamp 6 remains in contact with the curtain wall 1. Therefore, the gripper 4 moves relative to the connecting rod as it moves closer to the curtain wall 1, causing the amplifying wheel 81 inside the gripper 4 to rotate in the opposite direction. The reverse rotation of the amplifying wheel 81 will drive the amplifying limit rod 82 and the trigger pin 9 to rotate in the opposite direction. The reverse rotation of the trigger pin 9 will move to the right under the engagement of the amplifying limit ring 83 thread, until the trigger pin 9 loses contact with the retraction push rod 101. This causes the limiting connecting plate 733 to reset and move to the right under the action of the limiting spring 732. This causes the limiting block 734 on the limiting connecting plate 733 to move to the right and re-engage with the limiting locking groove 735. Finally, the gripper 4 is fixed to the housing 2 again, and the gripper 4 stops moving closer to the curtain wall 1, thus realizing the automatic adjustment of the clamping force of the clamp 6 on the curtain wall 1.

[0050] Example 3

[0051] Please see Figures 5 to 10An energy-saving prefabricated viewing wall for sunken plazas is provided, including an expansion adjustment component 11. The expansion adjustment component 11 includes an expansion push rod 111, an expansion groove 112, an expansion connecting plate 113, an expansion push block 114, an expansion friction ring 115, an expansion threaded column 116, an expansion threaded groove 117, a return spring 118, and a return ring 119. The expansion groove 112 is opened in the upper clamping rack 55 or the lower clamping rack 56 at the corresponding position of the right-side gripper 4. The expansion connecting plate 113 is slidably connected in the expansion groove 112. An expansion spring 1131 is provided between the right end of the expansion connecting plate 113 and the inner wall of the right-side gripper 4. The expansion push rod 111 is provided at the left end of the expansion connecting plate 113.

[0052] The right end of the trigger pin 9 engages with the expansion push rod 111. This engagement means that when the trigger pin 9 moves to the right and engages with the expansion push rod 111, as the trigger pin 9 continues to move to the right, it pushes the expansion push rod 111 to the right. An expansion threaded groove 117 is located at the center of the right end of the clamping gear 52. An expansion threaded pin 116 is threadedly connected to the expansion threaded groove 117. An expansion friction ring 115 is mounted on the expansion threaded pin 116. An expansion push block 114 is located at the right end of the expansion connecting plate 113. The right end of the sliding block 1142 engages with the left end of the expansion friction ring 115. This engagement means that when the expansion push rod 111 moves to the right, it drives the expansion connecting plate 113 to move to the right, compressing the expansion spring 1131. The rightward movement of the expansion connecting plate 113 drives the expansion push block 114 to move to the right, which in turn drives the sliding block 1142 to engage with the expansion friction ring 115. As the expansion push rod 111 continues to move to the right, the sliding block 1142 maintains frictional contact with the expansion friction ring 115 and pushes the expansion friction ring 115 to the right without rotating it. This causes the expansion friction ring 115 to drive the expansion threaded column 116 to move to the right. Because the sliding block 1142 is in frictional contact with the expansion friction ring 115, the expansion friction ring 115 will not rotate when it moves to the right. Consequently, the expansion threaded column 116 will not rotate when it moves to the right. This allows the expansion threaded column 116 to rotate in the opposite direction under the cooperation of the expansion threaded groove 117 in the housing 2 when it moves to the right. The reset ring 119 is slidably connected in the housing 2. The left end of the reset ring 119 is slidably connected to the right end of the expansion friction ring 115. One end of the reset spring 118 is connected to the right end of the reset ring 119, and the other end abuts against the inner wall of the housing 2.

[0053] The limiting block 734 is provided with a limiting chamfer 7341, and multiple limiting lock grooves 735 are provided. The limiting chamfer 7341 and the limiting lock grooves 735 cooperate. The cooperation here means that when the limiting block 734 and the limiting lock grooves 735 are in contact, when the expansion threaded column 116 moves to the right and drives the clamping gear 52 to rotate in the opposite direction, the upper clamping rack 55 and the lower clamping rack 56 on the upper and lower sides of the clamping gear 52 drive the jaw 4 to move, so that the jaw 4 moves away from the curtain wall 1. During the movement of the curtain wall 1, taking the upper clamping rack 55 at the front end as an example: when the upper clamping rack 55 on the left side moves away from the curtain wall 1 (that is, moves forward as shown in the figure), it will drive the internal limiting plate 733 to move forward. The forward movement of the limiting plate 733 will drive the limiting block 734 to move forward. The limiting chamfer 7341 at the front end of the limiting block 734 will continuously push the limiting block 734 to the left and squeeze the limiting spring 732 along the limiting groove until the upper clamping rack 55... When the forward movement stops, the limiting block 734, under the action of the limiting spring 732, re-inserts into the limiting lock groove 735, thus limiting and fixing the gripper 4, preventing the gripper 4 from moving backward under the action of gravity, and preventing the clamping head 6 from clamping the curtain wall 1 too tightly; when the upper clamping rack 55 on the right moves away from the curtain wall 1, the upper clamping rack 55 on the right moves its internal expansion connecting plate 113 away from the curtain wall 1, thereby driving the expansion push block 114 away from the curtain wall 1. When the sliding block 1142 moves to the side, its right side is in contact with the expansion friction ring 115, and because the sliding block 1142 is slidably connected to the expansion push block 114, the sliding block 1142 will slide and compress the sliding spring 1143 within the expansion push block 114 when the expansion push block 114 moves away from the curtain wall 1. This ensures that the frictional contact between the sliding block 1142 and the expansion friction ring 115 is not affected when the upper clamping rack 55 on the right side moves away from the curtain wall 1.

[0054] The rest of the structure is the same as in Example 2.

[0055] When the ambient temperature is high, the overall thickness and length of the curtain wall 1 will expand due to heat. As the thickness increases, the clamping force of the clamps 6 on the curtain wall 1 will also increase, and the overall length of the curtain wall 1 will also increase due to heat. There is a risk that the bottom may come into contact with an object below it and experience stress. When the thermal expansion reaches a certain point and adjustment is needed, the curtain wall 1 will gradually push the clamps 6 on both sides closer to the jaws 4, further compressing the connecting spring 72. The clamps 6 moving closer to the jaws 4 will cause the connecting rod 71 to move closer to the jaws 4. When the connecting rod 71 moves to one side of the jaws 4, it will cause the release... The large wheel 81 rotates in the opposite direction, which in turn drives the amplifying limit rod 82 and the trigger pin 9 to rotate in the opposite direction. The amplifying limit wheel is then limited by the amplifying pointer 84. Therefore, the adjusting pin slides to the right along the thread on the amplifying limit rod 82 until the trigger pin 9 moves to the right and engages with the expansion push rod 111. As the trigger pin 9 continues to move to the right, it pushes the expansion push rod 111 to the right. When the expansion push rod 111 moves to the right, it drives the expansion push block 114 to move to the right. As block 114 moves to the right, it causes sliding block 1142 to engage with expansion friction ring 115. With the continued rightward movement of expansion push rod 111, the frictional engagement between sliding block 1142 and expansion friction ring 115 prevents the ring from rotating. This allows expansion threaded column 116 to move to the right, engaging with expansion threaded groove 117 within housing 2, causing clamping gear 52 to rotate in the opposite direction. The reverse rotation of clamping gear 52 drives the upper clamping rack 55 and lower clamping rack 56 on both sides away from the curtain. When wall 1 moves to one side, it causes the clamps 4 on both sides to move away from the curtain wall 1. This reduces the compression of the spring 72 connecting the clamps 4 and the clamp head 6, thereby reducing the clamping force of the clamp head 6 on the curtain wall 1. This prevents the clamp head 6 from clamping the curtain wall 1 for too long, which could damage the interlayer of the glass in the energy-saving curtain wall 1 and allow moisture in the air to enter. It also prevents the formation of bubbles due to temperature changes, which would affect the aesthetics and viewing effect of the energy-saving viewing curtain wall 1. Furthermore, it avoids the energy-saving effect of the glass in the energy-saving curtain wall 1 from decreasing due to damage to the interlayer.

[0056] When the clamping gear 52 rotates in the reverse direction, the clamping gear 52, in conjunction with the central rack 53, drives the housing 2 to move upward as a whole, which in turn drives the jaws 4 and chucks 6 on both sides of the housing 2 to move upward, thereby causing the curtain wall 1 held by the chucks 6 to move upward as a whole. It cleverly utilizes the compressive force of the thickness expansion of the curtain wall 1 when heated to lift the curtain wall 1 as a whole, and adjusts the clamping force of the chucks 6 on the curtain wall 1 to prevent the curtain wall 1 from contacting the bottom gap due to the longitudinal length change caused by heating, and to prevent the bottom of the curtain wall 1 from being stressed. At the same time, it prevents the curtain wall 1 from becoming thicker due to heating, which would cause the chucks 6 to clamp the curtain wall 1 too tightly, and damage the laminated layer of the energy-saving curtain wall 1 glass under long-term clamping. It also prevents water vapor from entering around the area where the laminated layer is clamped too tightly, forming air bubbles, and preventing it from affecting the aesthetics of the energy-saving curtain wall 1 glass and the energy-saving effect of the laminated layer.

[0057] After the curtain wall 1 expands due to heat, the trigger pin 9 moves to the right until it abuts against the expansion push rod 111. The expansion connecting plate 113 moves to the right to compress the expansion spring 1131. The expansion push block 114 drives the sliding block 1142 to push the expansion friction ring 115 to the right, causing the expansion threaded pin 116 to move a certain distance to the right relative to the clamping gear 52. When the ambient temperature around the curtain wall 1 drops, causing the curtain wall 1 to cool and shrink in thickness, the clamp 6 remains in contact with the curtain wall 1 under the action of the connecting spring 72. The clamp 6 drives the connecting rod 71 to move away from the clamp 4. The movement causes the amplifying wheel 81, the amplifying limit rod 82, and the trigger pin 9 to rotate in the forward direction, thereby moving the trigger pin 9 to the left. During this process, since the left end of the trigger pin 9 has not yet contacted the retraction push rod 101, the limiting block 734 and the limiting lock groove 735 are in a engaged state, and the gripper 4 is locked to the housing 2. As the trigger pin 9 moves to the left, the expansion push rod 111 at the right end of the trigger pin 9 moves to the left and resets under the action of the expansion spring 1131, causing the expansion connecting plate 113, the expansion push block 114, and the sliding block 1142 to move to the left and reset together.

[0058] Until the expansion spring 1131 is fully reset, the sliding block 1142 disengages from the expansion friction ring 115. The sliding block 1142 is reset under the action of the reset spring 118. At the same time, since the gripper 4 and the housing 2 are locked, the clamping gear 52 is locked. During the process of the sliding block 1142 moving to the left to reset, the left end of the expansion friction ring 115 is not pushed. Therefore, under the sliding contact of the right end reset ring 119 and the push of the reset spring 118, combined with the locked state of the clamping gear 52, the expansion friction ring 115 and the expansion friction post move to the left while rotating under the action of the expansion thread groove 117, and finally fully reset, which is convenient for the next expansion adjustment.
