Description

Technical Field

[0001] The present invention relates to the technical field of installation of energy-saving glass curtain walls, and particularly to a prefabricated energy-saving viewing wall for a sunken square. Background Art

[0002] As an important spatial form in modern urban architecture, sunken squares are widely used in commercial complexes, transportation hubs, and public landscape projects due to their unique spatial hierarchy and coordination with the surrounding environment. To meet the requirements of daylighting, visual permeability, and aesthetics, large-area glass curtain walls are usually used as the enclosure structure for sunken squares. However, traditional glass curtain walls have obvious deficiencies in energy-saving performance, resulting in increased building energy consumption, specifically manifested as poor heat insulation performance and low utilization rate of natural light.

[0003] In recent years, energy-saving glass curtain walls (such as Low-E coated glass, insulating glass filled with inert gas, photovoltaic integrated glass, etc.) have gradually become the preferred solution for sunken square curtain walls due to their excellent heat insulation and light regulation capabilities. Such curtain walls can not only effectively reduce the air-conditioning load in summer and heating energy consumption in winter, but also optimize indoor daylighting through intelligent dimming technology, reduce the dependence on artificial lighting, and thus significantly improve the energy utilization efficiency of buildings. Since the curtain walls of sunken squares are usually large in area, in order to meet the requirements that the structure can bear large loads, ensure the safety and installation convenience of the curtain wall, and at the same time not damage the middle interlayer of the energy-saving glass curtain wall (such as the interlayer of laminated glass), a clamping and hanging installation method is mostly adopted.

[0004] During actual use, the thermal expansion and contraction effect caused by temperature changes in the glass curtain wall may lead to changes in the clamping force of the hanging clips on the clamping connection nodes of the glass curtain wall. Especially for energy-saving glass curtain walls, because they are provided with an interlayer or an inflated cavity in the middle and generally have two or more layers of glass, the overall thickness change is more obvious compared with ordinary glass curtain walls. Traditional glass curtain wall hanging clips cannot adjust the influence brought by the stress change of the clamping point caused by thermal expansion and contraction of the curtain wall. Especially in areas with large day-night temperature differences or significant seasonal temperature differences, when the thickness of the energy-saving glass curtain wall changes, such as triple-glazed double-pane energy-saving glass, on the one hand, when heated and expanded, it may cause the clamping force of the hanging clips on the curtain wall to be too tight, resulting in long-term excessive stress concentration at the clamping points of the curtain wall, making the interlayer prone to damage, and moisture in the air easily enters to form bubbles, affecting the energy-saving effect and even causing damage to the glass surface; on the other hand, when cooled and contracted, it will cause the clamping force at the clamping points to be insufficient, and the overall weight of the energy-saving curtain wall glass is relatively large, resulting in unstable clamping and prone to structural loosening problems, which not only affect the energy-saving performance of the curtain wall but also may pose safety hazards.

[0005] Therefore, a prefabricated energy-saving viewing wall for a sunken square is proposed. Summary of the Invention

[0006] The object of the present invention is to provide a prefabricated energy-saving viewing wall for a sunken square, in order to solve the problem existing in the prior art that the clamping force of the traditional glass curtain wall hanging clip is fixed, and when the thickness of the curtain wall glass changes due to thermal expansion and contraction, different clamping forces cannot be changed. Especially for energy-saving curtain wall glass with a relatively heavy mass and obvious thickness change, the curtain wall glass is prone to damage to the energy-saving glass interlayer due to too tight clamping force under the influence of thermal expansion and contraction, or the clamping is unstable due to too loose clamping force, resulting in potential safety hazards.

[0007] To achieve the above object, the present invention provides the following technical solutions:

[0008] A prefabricated energy-saving viewing wall for a sunken square includes a curtain wall, a housing, a suspension rod, a clamping jaw, a clamping component, a chuck, a limiting component, an amplifying component, a trigger post, a contraction adjustment component, and an expansion adjustment component.

[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 in the clamping jaw. The lower end of the amplifying wheel is in contact with the upper end of the connecting rod.

[0014] Preferably, the contraction adjusting component includes a contraction push rod and a movable groove. The contraction push rod is arranged at the right end of the limiting connecting plate. The movable groove is opened on the installation lock plate. The amplifying pointer cooperates with the movable groove. The left end of the trigger post cooperates with the contraction 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.

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

[0019] By arranging chucks and clamping jaws on both sides of the curtain wall, the chucks clamp the friction blocks on both sides of the curtain wall. After the clamping component clamps the curtain wall to an appropriate force, it stops. By arranging the trigger post and the amplification component, when the curtain wall cools and contracts, the clamping force of the chuck on the curtain wall is increased through the contraction adjustment component in cooperation with the trigger post. By arranging the expansion adjustment component, when the curtain wall expands due to heat, the clamping force of the chuck on the curtain wall is reduced in cooperation with the trigger post, thereby realizing the automatic adjustment of the clamping force of the curtain wall glass, so that the curtain wall glass always maintains an appropriate clamping force, preventing the clamping force from being too tight and damaging the interlayer, affecting the energy-saving effect and aesthetics, and at the same time preventing the clamping force from being too loose, resulting in unstable clamping and reducing potential safety hazards.

Detailed implementation mode

[0031] For a clear and complete description of the technical solutions in the embodiments of the present invention, and to make the features and advantages more obvious and understandable, the following provides a detailed description of the specific embodiments of the present invention with reference to the accompanying drawings of the specification. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the scope of protection of the present invention.

[0032] Embodiment 1

[0033] Please refer to Figures 1 to 6 , the present invention provides a prefabricated energy-saving viewing wall for a sunken square, including a curtain wall 1, a housing 2, a suspension rod 3, a clamping jaw 4, a clamping component 5, a chuck 6, a limiting component 7, a magnifying component 8, a trigger post 9, a contraction adjustment component 10, and an expansion adjustment component 11. Friction blocks 12 are provided at the front and rear ends of the curtain wall 1. The housing 2 and the suspension rod 3 are sequentially connected to the upper end of the curtain wall 1 from bottom to top. The upper end of the suspension rod 3 is fixedly connected to the bearing main body. The clamping jaws 4 are provided at the front and rear ends of the housing 2. Two groups of clamping jaws 4 are provided on each end of the housing 2. The chuck 6 is slidably connected to the clamping jaw 4. The limiting component 7 is connected between the chuck 6 and the clamping jaw 4, and is used to fix the clamping jaw 4 after the chuck 6 and the friction block 12 are clamped and fitted with a certain force. The trigger post 9 is connected between the two clamping jaws 4 at each end of the housing 2. The magnifying component 8 is provided on the clamping jaw 4, and is used to drive the trigger post 9 to move left and right after the relative displacement between the chuck 6 and the clamping jaw 4. The contraction adjustment component 10 is provided at the left end of the trigger post 9. When the curtain wall 1 contracts due to excessive cold, it cooperates with the magnifying component 8 to move the trigger post 9 to the left, and unlocks the clamping jaw 4 to increase the clamping force of the chuck 6 on the curtain wall 1 in combination with the self-weight of the curtain wall 1. The expansion adjustment component 11 is provided at the right end of the trigger post 9. When the curtain wall 1 expands due to excessive heat, it cooperates with the magnifying component 8 to move the trigger post 9 to the right, and expands the clamping jaw 4 to reduce the clamping force of the chuck 6 on the curtain wall 1.

[0034] Specifically, the curtain wall 1 is made of three-glass two-glue glass, that is, it is composed of three pieces of glass and two layers of intermediate glue. The three-glass two-glue energy-saving glass is used as the viewing wall of the sunken square. On the one hand, it provides super strong safety and impact resistance. The three-glass superimposed structure can withstand the wind pressure and accidental impact (such as equipment collision) around the sunken square. The safety is much higher than that of ordinary glass. At the same time, it has good sound insulation and noise reduction functions, especially when used in a sunken square with a large flow of people. The noise reduction effect is particularly important. At the same time, the glass uses ultra-white glass substrate to achieve a light transmittance of more than 90%, which reduces the oppressive feeling of the underground space and enhances natural lighting. The intermediate glue layer It can filter 99% of ultraviolet rays, protect the decoration in the sunken square from fading, extend the service life, and has a good energy-saving effect; the friction block 12 is composed of epoxy resin glue, non-woven fabric and copper sheet, which are sequentially adhered to the front and rear ends of the curtain wall 1, and a card 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 and the card groove at the end of the copper sheet away from the curtain wall 1 are in contact and locked, thereby increasing the friction and locking performance of the contact point between the clamp 6 and the copper sheet, and the curtain wall 1 will not be loose due to the use of three-glass two-cavity glass, which makes the overall quality much higher than that of ordinary glass, thereby causing insufficient friction between the clamp 6 and the friction block 12.

[0035] The clamping component 5 includes a clamping groove 51, a clamping gear 52, a center rack 53, a clamping limit rod 54, an upper clamping rack 55 and a lower clamping rack 56. There are two groups of clamping jaws 4 at the front and rear ends of the curtain wall 1. Each clamping jaw 4 is correspondingly provided with an upper clamping rack 55 or a lower clamping rack 56. In the figure, the upper clamping rack 55 is connected to the clamping jaw 4 at the front end of the curtain wall 1, and the lower clamping rack 56 is connected to the clamping jaw 4 at the rear end of the curtain wall 1. The specific installation situation can be appropriately adjusted according to the matching position of the center rack 53 and the clamping gear 52. The clamping groove 51 is opened in the shell body 2, the clamping gear 52 is rotatably connected in the clamping groove 51, the clamping limit rod 54 and the center rack 53 are respectively fixedly connected to the front and rear ends of the suspension rod 3, the center rack 53 is meshed 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 are respectively meshed with the upper and lower ends of the clamping gear 52, the upper clamping rack 55 is connected to the clamping claw 4 at the front end of the curtain wall 1, and the lower clamping rack 56 is connected to the clamping claw 4 at the rear end of the curtain wall 1.

[0036] Adopt the energy-saving glass curtain wall 1 with three glasses and two adhesives. On the one hand, it can achieve many energy-saving effects. On the other hand, because the glass of the three-glass-two-adhesive type is heavier than the general glass curtain wall 1, after the chuck 6 is engaged with the friction block 12, the curtain wall 1 can provide enough weight to apply weight to the housing 2. Then, under the tension of the hanging rod 3 and the action of the clamping member 5, the gravity of the three-glass-two-adhesive type glass curtain wall 1 is converted into a clamping force, thereby meeting the clamping force requirement of the chuck 6 for the glass curtain wall 1. When the friction force and the engagement degree of the friction block 12 and the chuck 6 are sufficient, the overweight glass curtain wall 1 can even provide an excessive amount of gravity to be converted into a clamping force.

[0037] The limiting member 7 includes a connecting rod 71, a connecting spring 72 and a fixing unit 73. The fixing unit 73 is used to fix the clamping jaw 4. The connecting rod 71 is slidably connected to the clamping jaw 4. The side of the connecting rod 71 close to the curtain wall 1 is fixedly connected to the chuck 6. The two ends of the connecting spring 72 are respectively connected to the side of the chuck 6 away from the curtain wall 1 and the side of the connecting rod 71 close to the curtain wall 1. The connecting spring 72 is selected as an invar alloy spring, so that within the normal temperature range of minus 20 degrees Celsius to 80 degrees Celsius, it hardly undergoes thermal expansion and contraction deformation effects, ensuring the stability of the clamping force. A scale can be set on the connecting rod 71 to reflect the compression force of the connecting spring 72. The scale is not shown in the figure, so as to accurately reflect the clamping force of the glass of the curtain wall 1 and prevent the laminated glass layer (such as PVB / SGP) from separating from the glass surface in the pressure concentration area due to excessive squeezing of the glass edge during hanging and clamping, forming tiny voids, resulting in the expansion of the air or water vapor remaining in the voids and forming visible bubbles.

[0038] The fixing unit 73 includes a limiting sliding groove 731, a limiting spring 732, a limiting connecting plate 733, a limiting block 734, a limiting locking groove 735, a mounting locking block 736 and a mounting locking plate 737. The limiting sliding groove 731 is opened in the clamping jaw 4 at the left end and the upper clamping rack 55 or the lower clamping rack 56 at the corresponding position. The limiting connecting plate 733 is slidably connected in the limiting sliding groove 731. The right end of the limiting connecting plate 733 is provided with a mounting locking block 736, and the mounting locking block 736 is provided with a mounting chamfer 7361. The mounting locking plate 737 is slidably connected to the clamping jaw 4, and the mounting locking plate 737 cooperates with the mounting chamfer 7361. The cooperation here means that when adjusting the clamping force of the chuck 6 on the glass curtain wall 1, first push the mounting locking plate 737 upward. During the upward movement of the mounting locking plate 737, the mounting locking plate 737 will first fit with the mounting chamfer 7361 and push the limiting connecting plate 733 to the left to compress the limiting spring 732 along the mounting chamfer 7361. The leftward movement of the limiting connecting plate 733 drives the limiting block 734 to move leftward until the right end of the mounting locking block 736 completely moves into the hole of the mounting locking plate 737. At this time, the limiting block 734 is completely pulled out of the limiting locking groove 735, realizing that when adjusting the position of the clamping jaw 4, the clamping jaw 4 can be kept in an unlocked state. Both ends of the limiting spring 732 are connected to the left end of the limiting connecting plate 733 and the inner wall of the clamping jaw 4 respectively. The limiting locking groove 735 is opened in the housing 2, and the limiting block 734 is arranged at the right ends of the upper clamping rack 55 and the lower clamping rack 56 on the left side. The limiting block 734 cooperates with the limiting locking groove 735. The cooperation here means that when the limiting spring 732 is in a normal state, the limiting block 734 will be inserted into the limiting locking groove 735 under the action of the elastic force of the limiting spring 732.

[0039] When hanging the glass curtain wall 1, first fix the suspender 3 at the designated position, push the installation lock plate 737 upward to the position of the installation lock block 736, restrict the connecting plate 733 from extruding the restricting spring 732, and pull out the restricting block 734 from the restricting lock groove 735, so that the upper clamping rack 55 and the lower clamping rack 56 on the left side can slide back and forth in the housing 2. Then move the curtain wall 1 under the suspender 3, pull the whole housing 2 downward, make the chucks 6 on both sides approach the curtain wall 1 until the chucks 6 contact the copper sheet of the friction block 12. Then slowly lower the curtain wall 1 so that the gravity of the curtain wall 1 is gradually clamped and held by the suspender 3 and the chucks 6. During the process of slowly lowering the curtain wall 1, because the chuck 6 is stuck with the copper sheet, the curtain wall 1 will drive the chuck 6 and the whole housing 2 to move downward relative to the suspender 3. As a result, the clamping gear 52 in the housing 2 moves downward relative to the central rack 53 at the lower end of the suspender 3, and the clamping limit rod 54 is used to limit the direction of the housing 2 and the suspender 3. During the process of the clamping gear 52 moving downward relative to the central gear, the clamping gear 52 rotates forward, driving the upper clamping racks 55 and the lower clamping racks 56 on the upper and lower sides to approach the center of the housing 2, and then driving the jaws 4 on both sides to approach the curtain wall 1. At this time, because the chuck 6 is stuck and abutted with the friction block 12 on the curtain wall 1, when the jaws 4 approach the curtain wall 1, the jaws 4 will approach the chuck 6 and squeeze the connecting spring 72, making the clamping force of the chuck 6 on the curtain wall 1 tighter and tighter. By reading the scale of the connecting rod 71 at the chuck 6, the clamping force is judged. After reaching the appropriate force to lift and clamp this type of glass curtain wall 1, at this time, the magnifying pointer 84 just keeps vertically upward, and then stop releasing the curtain wall 1. Then move the installation lock plate 737 downward along the jaw 4, so that the moving groove 102 of the installation lock plate 737 is sleeved on the magnifying pointer 84. The installation lock plate 737 completely moves to the lower end of the installation lock block 736, so that the restricting connecting plate 733 is reset under the action of the restricting spring 732. As a result, the restricting block 734 at the right end of the restricting connecting plate 733 is inserted into the restricting lock groove 735 again, realizing the fixation of the upper clamping rack 55 and the lower clamping rack 56 at the left end, thus stopping the housing 2 from continuing to move relative to the suspender 3 and also stopping the jaws 4 from continuing to approach the curtain wall 1, making the clamping force of the chuck 6 on the curtain wall 1 maintain at an appropriate force, preventing the curtain wall 1 from being too large, resulting in the curtain wall 1 being too heavy in mass, and then making the reaction force of the chuck 6 on the clamping force of the curtain wall 1 too large. Especially when it is used for fixing the laminated glass or triple-glazed two-seal glass curtain wall 1 with better energy-saving performance and heavier weight in the sunken square. If the clamping force is too large, it will over-extrude the upper edge of the glass during lifting and clamping, causing the laminated layer to separate from the edge to form tiny gaps. As the temperature rises and the water vapor expands, visible bubbles will be formed in the glass. On the one hand, it affects the viewing effect, and on the other hand, it affects the energy-saving efficiency, such as affecting the blocking of ultraviolet rays by the lamination.

[0040] Embodiment 2

[0041] Please refer to Figures 4 to 9, a prefabricated energy-saving viewing wall for a sunken square is provided, including an amplification component 8. The amplification component 8 includes an amplification wheel 81, an amplification limiting rod 82, an amplification limiting ring 83, and an amplification pointer 84. The amplification wheel 81 is rotatably connected within the jaw 4. The diameter of the amplification wheel 81 is preferably selected to be as small as possible. The frictional force on the upper surfaces of the amplification wheel 81 and the connecting rod 71 is large enough to meet the high frictional force requirements between the two. The purpose of designing the amplification wheel 81 is that even when there is a slight change in the overall thickness of the curtain wall 1 and the friction block 12, and the connecting rod 71 only undergoes a slight displacement, under the fitting friction between the amplification wheel 81 and the connecting rod 71, the amplification wheel 81 can rotate a certain angle, thereby driving a series of components such as the amplification limiting rod 82 to move.

[0042] The lower end of the amplification wheel 81 is in contact with the upper end of the connecting rod 71. The amplification limiting rod 82 is fixedly connected to the amplification wheel 81. The trigger post 9 is slidably connected in the left-right direction on the amplification limiting rod 82. The amplification limiting ring 83 is rotatably connected to the trigger post 9. The amplification pointer 84 is fixedly connected to the amplification limiting ring 83. The trigger post 9 and the amplification limiting ring 83 are connected by threads. Here, when the overall thickness of the curtain wall 1 in the middle of the chuck 6 changes, the chuck 6 will have a relative displacement with the fixed jaw 4, thereby causing the connecting rod 71 to move relative to the jaw 4. The movement of the connecting rod 71 drives the amplification wheel 81 to rotate accordingly. The amplification wheel 81 drives the trigger ring to rotate under the action of the amplification limiting rod 82. At this time, since the trigger post 9 and the amplification limiting ring 83 are connected by threads, and the amplification pointer 84 at the upper end of the amplification limiting 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 amplification limiting ring 83 and the amplification limiting rod 82.

[0043] When the glass of the curtain wall 1 is in use, especially energy-saving glass curtain walls 1 such as triple-glazed two-sealed glass and insulating glass with a relatively thick overall thickness, when the temperature changes greatly, the glass, the laminated layer, the insulating layer, the friction blocks 12 (such as epoxy resin glue and copper sheets) in the middle of the chuck 6, etc. will expand and contract thermally, causing changes in the overall thickness and length of the curtain wall 1 in the middle of the chuck 6. Especially for large sunken square viewing curtain walls 1, due to the large overall size and high quality of the glass curtain wall 1, and the edge being relatively brittle, therefore, the curtain wall 1 is generally clamped and supported by hanging clamps, and a gap is left below the curtain wall 1 to cope with the longitudinal thermal expansion and contraction changes of the glass of the curtain wall 1. The bottom of the curtain wall 1 is not used as the main support. Therefore, when the thickness changes, it will cause a change in the clamping force of the chuck 6 on the curtain wall 1. If it is too loose, the clamping effect will become poor, the bottom of the curtain wall 1 will bear the load, and there is a risk of damage. If it is too tight, the clamping at the upper end will be excessive. When used as an energy-saving laminated glass curtain wall 1, air bubbles may be generated in the laminated layer; when the length changes, when the length becomes longer, the bottom of the curtain wall 1 will gradually bear the load. When the length becomes shorter, it may cause the bottom of the curtain wall 1 to separate from the reserved gap, causing the bottom of the curtain wall 1 to lose the lateral limit fixation and also affecting the sealing effect between the inside and outside of the curtain wall 1.

[0044] The shrinkage adjustment component 10 includes a shrinkage push rod 101 and a movable groove 102. The shrinkage push rod 101 is arranged at the right end of the limiting connecting plate 733, and the movable groove 102 is opened on the installation 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 and the connecting rod 71 shows an appropriate clamping force, the magnifying pointer 84 is just in an upward vertical state at this time. Then, press down the installation lock plate 737 so that the movable groove 102 of the installation lock plate 737 can just cover the magnifying pointer 84 to realize the limit on the left and right ends of the magnifying pointer 84. There is a gap between the left and right ends of the trigger post 9 and the expansion push rod 111 and the shrinkage push rod 101. The purpose of this design is that the appropriate clamping force of the chuck 6 on the glass curtain wall 1 can be in an interval. Leaving a gap between the left and right ends of the trigger post 9 and the expansion push rod 111 and the shrinkage push rod 101 is to ensure that during the use of the curtain wall 1, even if there is a slight thickness change, as long as the clamping force of the chuck 6 on the curtain wall 1 is still within the appropriate range, then when the chuck 6 undergoes a slight displacement due to the thickness change of the curtain wall 1, and then drives the magnifying wheel 81, the magnifying limit rod 82, and the adjusting column to rotate, the adjusting column moves left and right under the limit of the magnifying limit ring 83, the magnifying pointer 84, and the installation lock plate 737, and will not come into contact with the expansion push rod 111 and the shrinkage push rod 101. Thus, the chuck 6 is within the appropriate clamping force interval and will not frequently adjust the clamping force, reducing wear and extending the service life of the device.

[0045] The left end of the trigger post 9 cooperates with the retraction push rod 101. The cooperation here means that when the curtain wall 1 and the friction blocks 12 contract due to cold to a certain extent, the overall thickness of the curtain wall 1 will shrink. Since the clamping jaws 4 and the housing 2 are in a fixed state, the two sides of the curtain wall 1 will move away from the clamping jaws 4, resulting in a decrease in the clamping force of the chuck 6 and the connecting spring 72 on the curtain wall 1. During this process, the chuck 6 will fit with the friction blocks 12 on both sides of the curtain wall 1 under the action of the connecting spring 72 and drive the connecting rod 71 to move closer to the curtain wall 1. When the connecting rod 71 moves, it will drive the amplification wheel 81 to rotate forward. The forward rotation of the amplification wheel 81 drives the amplification limit rod 82 and the trigger post 9 to rotate forward. Since the amplification limit wheel and the amplification pointer 84 are limited by the installation lock plate 737, the adjustment post will slide leftward on the amplification limit rod 82 along the thread between it and the amplification limit wheel until its left end abuts against the retraction push rod 101 and pushes the retraction push rod 101 to the left.

[0046] The remaining structures are the same as those in Embodiment 1.

[0047] After the glass curtain wall 1 is installed, when the environmental temperature is relatively low, the overall thickness and length of the curtain wall 1 will slightly decrease. After the thickness decreases to a certain extent, the clamping force of the chuck 6 on the curtain wall 1 will be lower than the appropriate range, and it is necessary to appropriately adjust the clamping force of the chuck 6 on the curtain wall 1 to prevent insufficient clamping force caused by too loose clamping, which may lead to the risk of the energy-saving laminated glass curtain wall 1 falling. At the same time, after the overall length of the curtain wall 1 shrinks to a certain extent, it is also necessary to appropriately adjust the longitudinal position of the curtain wall 1 to prevent the bottom of the curtain wall 1 from separating from the reserved gap, causing the bottom of the curtain wall 1 to lose the lateral limit.

[0048] During the process of the overall thickness of the curtain wall 1 of the assembled energy-saving viewing wall for the sunken square of this application becoming smaller, the chuck 6 fits with the friction blocks 12 on both sides of the curtain wall 1 under the action of the connecting spring 72, and drives the connecting rod 71 to move closer to the curtain wall 1. When the connecting rod 71 moves, it will drive the amplification wheel 81 to rotate forward. The forward rotation of the amplification wheel 81 drives the amplification limit rod 82 and the trigger post 9 to rotate forward. The adjustment post will slide leftward on the amplification limit rod 82 along the thread. When the overall thickness of the curtain wall 1 shrinks to a certain extent and the clamping force of the chuck 6 on the curtain wall 1 decreases to be almost lower than the appropriate range, 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. While the retraction push rod 101 moves leftward to push the limit connecting plate 733 to move leftward to compress the limit spring 732, it drives the limit block 734 on the limit connecting plate 733 to move leftward, so that the limit block 734 disengages from the insertion with the limit lock groove 735, thereby unlocking between the jaw 4 and the housing 2. At this time, under the action of the gravity of the curtain wall 1 and the frictional engagement between the friction block 12 of the curtain wall 1 and the chuck 6, the curtain wall 1 will drive the chuck 6, the jaw 4, and the housing 2 to move downward relative to the hanging rod 3. As a result, the clamping gear 52 in the housing 2 moves downward relative to the central rack 53 below the hanging rod 3. The clamping gear 52 rotates forward under the action of the central rack 53, driving the upper clamping racks 55 and the lower clamping racks 56 on the upper and lower sides to move closer to the center of the housing 2, thereby driving the jaws 4 on both sides to move closer to the curtain wall 1 and compress the connecting spring 72, so that the clamping force of the chuck 6 on the curtain wall 1 becomes larger until the clamping force of the chuck 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 contracting 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 the loss of lower limit, or reducing the sealing and heat preservation and energy-saving effects of the curtain wall 1;

[0049] During the process of the jaw 4 moving closer to the curtain wall 1, since the chuck 6 remains in contact with the curtain wall 1, therefore, the jaw 4 will move relative to the connecting rod during the process of moving closer to the curtain wall 1, and thus the amplification wheel 81 in the jaw 4 rotates reversely. The reverse rotation of the amplification wheel 81 drives the amplification limit rod 82 and the trigger post 9 to rotate reversely. The reverse rotation of the trigger post 9 will move rightward under the cooperation of the thread of the amplification limit ring 83 until the trigger post 9 loses contact with the retraction push rod 101, causing the limit connecting plate 733 to reset and move rightward under the action of the limit spring 732. As a result, the limit block 734 on the limit connecting plate 733 moves rightward to re-insert into the limit lock groove 735, and finally the jaw 4 is re-fixed to the housing 2, and the jaw 4 stops moving closer to the curtain wall 1, realizing the automatic adjustment of the clamping force of the chuck 6 on the curtain wall 1.

[0050] Embodiment 3

[0051] Please refer to Figures 5 to 10, provided is a prefabricated energy-saving viewing wall for a sunken square, 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 clamping jaw 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 clamping jaw 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 post 9 cooperates with the expansion push rod 111. Here, the cooperation means that when the trigger post 9 moves to the right and fits with the expansion push rod 111, as the trigger post 9 continues to move to the right, the trigger post 9 can push the expansion push rod 111 to move to the right. The expansion threaded groove 117 is opened at the center of the right end of the clamping gear 52. The expansion threaded column 116 is threadedly connected in the expansion threaded groove 117. The expansion friction ring 115 is provided on the expansion threaded column 116. The expansion push block 114 is provided at the right end of the expansion connecting plate 113. The right end of the sliding block 1142 cooperates with the left end of the expansion friction ring 115. Here, the cooperation means that when the expansion push rod 111 moves to the right, the expansion push rod 111 can drive the expansion connecting plate 113 to move to the right to compress the expansion spring 1131. The expansion connecting plate 113 moves to the right to drive the expansion push block 114 to move to the right. The expansion push block 114 moves to the right to drive the sliding block 1142 to fit with the expansion friction ring 115. And as the expansion push rod 111 continues to move to the right, the sliding block 1142 can maintain frictional contact with the expansion friction ring 115 and push the expansion friction ring 115 to the right without rotation, so that the expansion friction ring 115 drives the expansion threaded column 116 to move to the right. Since the sliding block 1142 is in frictional contact with the expansion friction ring 115, when the expansion friction ring 115 moves to the right, the expansion friction ring 115 will not rotate. Furthermore, when the expansion threaded column 116 moves to the right, it will not rotate either. Then, when the expansion threaded column 116 moves to the right, it can cooperate with the expansion threaded groove 117 in the housing 2 to reverse the rotation of the clamping gear 52. The return ring 119 is slidably connected in the housing 2. The left end of the return ring 119 is slidably connected to the right end of the expansion friction ring 115. One end of the return spring 118 is connected to the right end of the return ring 119, and the other end abuts against the inner wall of the housing 2.

[0053] A limiting chamfer 7341 is provided on the limiting block 734, and a plurality of limiting locking grooves 735 are provided. The limiting chamfer 7341 cooperates with the limiting locking grooves 735. Herein, the cooperation means that when the limiting block 734 is in contact with the limiting locking grooves 735, when the expansion screw post 116 moves to the right to drive the clamping gear 52 to rotate reversely, the upper clamping rack 55 and the lower clamping rack 56 on the upper and lower sides of the clamping gear 52 drive the clamping jaws 4 to move, so that the clamping jaws 4 move away from the curtain wall 1. During the process of the clamping jaws 4 moving away from the curtain wall 1, taking the upper clamping rack 55 at the front end as an example here: when the left upper clamping rack 55 moves away from the curtain wall 1 (that is, moves forward in the figure), it will drive the limiting connecting plate 733 inside it to move forward. The forward movement of the limiting connecting 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 stops moving forward. At this time, the limiting block 734 is inserted into the limiting locking groove 735 again under the action of the limiting spring 732, so as to limit and fix the clamping jaws 4, so that the clamping jaws 4 cannot move backward under the action of gravity, and prevent the chuck 6 from clamping the curtain wall 1 too tightly; when the right upper clamping rack 55 moves away from the curtain wall 1, the right upper clamping rack 55 drives the expansion connecting plate 113 inside it to move away from the curtain wall 1, and then drives the expansion push block 114 to move to the side away from the curtain wall 1. Since the right side of the sliding block 1142 is in contact with the expansion friction ring 115 and the sliding block 1142 is slidably connected to the expansion push block 114, therefore, when the expansion push block 114 moves to the side away from the curtain wall 1, the sliding block 1142 will slide relative to the expansion push block 114 and squeeze the sliding spring 1143, so as to ensure that when the right upper clamping rack 55 moves away from the curtain wall 1, it will not affect the friction contact effect between the sliding block 1142 and the expansion friction ring 115.

[0054] The rest of the structure is the same as that of Embodiment 2.

[0055] When the ambient temperature is relatively high, the overall thickness and length of the curtain wall 1 will expand due to heat. When the thickness increases, the clamping force of the chuck 6 on the curtain wall 1 will increase, and the overall length of the curtain wall 1 will also become longer due to heat. There is a risk that the bottom will abut against the lower object and bear force. When adjustment is required after thermal expansion reaches a certain level, the curtain wall 1 will gradually push the chucks 6 on both sides closer to the clamping claws 4 and further compress the connecting spring 72. When the chuck 6 moves closer to the clamping claw 4, it drives the connecting rod 71 to move closer to the clamping claw 4. When the connecting rod 71 moves towards the clamping claw 4, it drives the amplification wheel 81 to rotate in the reverse direction. The reverse rotation of the amplification wheel 81 drives the amplification limit rod 82 and the trigger post 9 to rotate in the reverse direction, while the amplification limit wheel is limited by the amplification pointer 84. Therefore, the adjustment post will slide to the right along the thread on the amplification limit rod 82 until the trigger post 9 moves to the right and fits with the expansion push rod 111. As the trigger post 9 continues to move to the right, the trigger post 9 can push the expansion push rod 111 to move to the right. When the expansion push rod 111 moves to the right, the expansion push rod 111 can drive the expansion push block 114 to move to the right. The rightward movement of the expansion push block 114 drives the sliding block 1142 to fit with the expansion friction ring 115. As the expansion push rod 111 continues to move to the right, under the frictional fit between the sliding block 1142 and the expansion friction ring 115, the expansion friction ring 115 can only move to the right and will not rotate. This enables the expansion threaded column 116 to expand in the expansion thread groove 117 in the housing 2 when moving to the right, causing the clamping gear 52 to rotate in the reverse direction. The reverse rotation of the clamping gear 52 drives the upper clamping rack 55 and the lower clamping rack 56 on the upper and lower sides to move away from the curtain wall 1, thereby driving the clamping claws 4 on both sides to move away from the curtain wall 1, so as to reduce the compression degree of the connecting spring 72 between the clamping claws 4 and the chuck 6, and further reduce the clamping force of the chuck 6 on the curtain wall 1, so as to prevent the chuck 6 from clamping the curtain wall 1 excessively for a long time, resulting in the entry of water vapor in the air due to the damage of the laminated glass layer of the energy-saving curtain wall 1, preventing the formation of bubbles due to the alternation of cold and heat, affecting the aesthetics and viewing effect of the energy-saving viewing curtain wall 1, and also avoiding the decline of the energy-saving effect of the energy-saving curtain wall 1 glass due to the damage of the laminated glass layer.

[0056] When the clamping gear 52 rotates in the reverse direction, the clamping gear 52 will drive the entire housing 2 to move upward in cooperation with the central rack 53, thereby driving the clamping claws 4 and the chucks 6 on both sides of the housing 2 to move upward, thus driving the entire curtain wall 1 clamped by the chuck 6 to move upward. Cleverly utilize the extrusion force generated by the thickness expansion of the entire curtain wall 1 when heated to lift the entire curtain wall 1 upward and adjust the clamping force of the chuck 6 on the curtain wall 1, preventing the curtain wall 1 from contacting the reserved gap at the bottom due to the longitudinal length change caused by heat, preventing the bottom of the curtain wall 1 from bearing force and being strained. At the same time, prevent the thickness of the curtain wall 1 from increasing due to heat, resulting in the chuck 6 clamping the curtain wall 1 too tightly, damaging the laminated glass layer of the energy-saving curtain wall 1 under long-term clamping, preventing water vapor from entering the surrounding area where the laminated glass layer is clamped too tightly to form bubbles, and preventing the impact on the aesthetics of the energy-saving curtain wall 1 glass and the energy-saving effect of the laminated glass layer.

[0057] After the curtain wall 1 expands and adjusts its thickness due to heat, the trigger post 9 moves to the right until it abuts against the expansion push rod 111. The expansion connecting plate 113 moves to the right and compresses 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 post 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 be cooled and its thickness to shrink, at this time, the chuck 6 remains in contact with the curtain wall 1 under the action of the connecting spring 72. The chuck 6 drives the connecting rod 71 to move relatively away from the side of the jaw 4, thereby driving the magnifying wheel 81, the magnifying limit rod 82, and the trigger post 9 to rotate forward, so that the trigger post 9 moves to the left. During this process, since the left end of the trigger post 9 has not yet contacted the contraction push rod 101, therefore, the limiting block 734 and the limiting lock groove 735 are in a mating state, and the jaw 4 is locked with the housing 2. During the process of the trigger post 9 moving to the left, the expansion push rod 111 at the right end of the trigger post 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 completely reset, the sliding block 1142 disengages from the contact with the expansion friction ring 115, and the sliding block 1142 resets under the action of the reset spring 118. At the same time, since the jaw 4 is locked with the housing 2, therefore, the clamping gear 52 is in a locked state. During the process of the sliding block 1142 moving to the left and resetting, the left end of the expansion friction ring 115 is not subjected to a thrust force. Therefore, under the sliding contact of the right end reset ring 119 of the expansion friction ring 115, and the push of the reset spring 118, combined with the locked state of the clamping gear 52, the expansion friction ring 115 moves to the left while rotating under the action of the expansion thread groove 117, and finally resets completely, facilitating the next expansion adjustment.
