Description

Technical Field

[0001] The invention relates to a curtain wall, in particular to an energy-saving curtain wall for building decoration applied in the curtain wall field. Background Art

[0002] The curtain wall is the exterior wall of a building. It does not bear weight and is hung like a curtain, so it is also called a "curtain wall". It is a lightweight wall with decorative effects commonly used in modern large and high-rise buildings. It is composed of panels and a supporting structure system, and has a certain displacement ability relative to the main structure or a certain deformation ability of itself, and does not bear the effects of the main structure. It is an exterior protective structure or decorative structure of the building.

[0003] Since curtain walls are more fragile than exterior walls and have a relatively high maintenance frequency, they generally need to be inspected, maintained and replaced regularly, which requires that the curtain walls be easy to replace. For example, the specification of patent application number CN202210360221.4 discloses a method for replacing broken glass in a building curtain wall, wherein the building curtain wall is composed of a curtain wall unit formed by a plurality of glass panels and a mounting frame, and the mounting frame is movably connected with adjacent baffles and give-way plates; the glass replacement method includes removing the glass panel and placing it in a safety bucket, cleaning up the glass debris, and removing the sealant on the mounting frame; transporting the new glass panel and external construction personnel to the construction site by a crane, storing the baffles and give-way plates, sucking the new glass panel inside and outside with suction cups and positioning it in the mounting groove, so that the baffles and give-way plates are respectively abutted against the corresponding parts of the glass panel, and finally applying glass panel sealant around the glass panel. When the glass plate is installed, the movement of the baffle plate and the clearance plate provides clearance space. After installation, the baffle plate and the clearance plate abut against each other to play a further positioning role, thereby conveniently replacing the broken glass plate and reducing the difficulty of operation.

[0004] However, the gaps between existing curtain wall panels are very small, leaving almost no operating space, making it difficult to remove them. If the removal method of breaking the glass is adopted, although it is quick and convenient, the removed curtain wall panels will be immediately scrapped and will no longer be useful for reuse. Similarly, since the gaps between the curtain wall panels are too small, it is also difficult to install new curtain wall panels. Therefore, an energy-saving curtain for architectural decoration is proposed to improve the above problems. Summary of the invention

[0005] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is that the gaps between the existing curtain wall panels are very small, and there is almost no operating space, which makes it difficult to dismantle them. If the removal method of breaking the glass is adopted, although it is quick and convenient, the dismantled curtain wall panels are immediately scrapped and can no longer be reused. Similarly, since the gaps between the curtain wall panels are too small, it is also more laborious to install new curtain wall panels.

[0006] In order to solve the above problems, the present invention provides a building decorative energy-saving curtain wall, including a curtain wall panel and a connecting mechanism installed between the curtain wall panel and an inherent mounting frame:

[0007] The connecting mechanism includes a telescopic connecting component and an operating component, and the telescopic connecting component includes a fixed part and a movable part;

[0008] The movable part is fixed on the back of the curtain wall panel, the fixed part is fixed on the inherent mounting frame, and the fixed part is slidably sleeved on the outer side of the movable part;

[0009] A reset piece is installed between the fixed part and the movable part, and the operating assembly is installed on the fixed part.

[0010] In the above-mentioned building decoration energy-saving curtain wall, by installing a connection mechanism including a retractable connection component and an operating component between the curtain wall panel and the inherent mounting frame, the curtain wall panel can be directly sucked by a suction cup and pulled outward, so that the retractable connection component can be unfolded, thereby facilitating and stably disassembling and assembling the curtain wall panel, making the operation more convenient and reliable, and being able to ensure the integrity of the disassembled curtain wall panel, facilitating recycling and reuse, and being more energy-efficient.

[0011] As a further supplement to the present application, the fixing portion includes a fixing sleeve and a first mounting sheet;

[0012] The fixed sliding sleeve is slidably sleeved on the outer side of the movable part, and the first mounting piece is fixed to the end of the fixed sliding sleeve away from the movable part and is fixed to the inherent mounting frame;

[0013] The operating assembly is installed on the side end of the fixed sliding sleeve close to the movable part, and the reset piece is fixed between the movable part and the inner side of the fixed sliding sleeve.

[0014] As a further supplement to the present application, the movable portion includes a sliding post and a second mounting plate;

[0015] The sliding column is slidably sleeved on the inner side of the fixed sliding sleeve, and the second mounting piece is fixed to the end of the sliding column away from the fixed portion and fixed to the curtain wall panel;

[0016] A groove is arranged at the side end of the sliding column, a limit block is slidably installed inside the groove, and an elastic member is fixed between the limit block and the bottom of the groove;

[0017] A limiting through hole is provided at the side end of the fixed sliding sleeve close to the movable part for the limiting block to penetrate, and the operating component is located at the limiting through hole;

[0018] The reset piece is fixed between the inner side of the fixed sliding sleeve and the end of the sliding column.

[0019] As a further supplement to the present application, a side end of the fixed sleeve close to the first mounting plate is provided with an avoidance groove for the limit block to pass through, and the edge of one side of the upper end of the limit block close to the second mounting plate is provided with a chamfer; the avoidance groove can be used for the limit block to be naturally placed when the curtain wall panel is installed, thereby maintaining the original length of the elastic part and preventing the elasticity from being weakened due to being in a compressed state for a long time.

[0020] As a further supplement to the present application, a limiting protrusion is provided on the inner wall of the end of the fixed sleeve away from the first mounting plate, and a strip groove that slides with the limiting protrusion is provided on the side end of the sliding column. The setting of the limiting protrusion can effectively prevent the sliding column from completely separating from the fixed sleeve.

[0021] As a further supplement to the present application, two retractable connection components are provided, and the two retractable connection components are respectively located on opposite sides of the back side of the curtain wall panel, and the operating component is connected between two fixed sliding sleeves; the connection structure is symmetrically installed on opposite sides of the back side of the curtain wall panel to ensure the stability of its connection.

[0022] As a further supplement to the present application, the operating assembly includes a rotating shaft and a transmission structure;

[0023] The rotating shaft is rotatably installed between the two rotating shafts, the two ends of the rotating shaft are connected with the two fixed sliding sleeves through a transmission structure, and a rotating handle is fixed at one end of the rotating shaft.

[0024] As a further supplement to the present application, the transmission structure includes a first bevel gear, a second bevel gear, a threaded rod, a threaded square sleeve and a return sleeve;

[0025] A fixed frame is fixed to the side end of the fixed sleeve, the first bevel gear is coaxially fixed to the rotating shaft, and the second bevel gear is coaxially fixed to the threaded rod and meshes with the first bevel gear;

[0026] The threaded rod is rotatably installed on the fixed frame, the threaded square sleeve is threadedly sleeved on the outside of the threaded rod, the return sleeve is fixed to the side end of the fixed sliding sleeve, and is slidably sleeved on the outside of the threaded square sleeve. After replacing the new curtain wall panel, manually rotate the handle to make the rotating shaft rotate with the first bevel gear, and the first bevel gear drives the second bevel gear to rotate with the threaded rod, and the threaded rod drives the threaded square sleeve to slide toward the limit block in the return sleeve until the threaded square sleeve squeezes the limit block into the groove. At this time, the sliding column pulls the curtain wall panel toward one side of the inherent mounting frame under the action of the reset member until the curtain wall panel is on the same plane as other curtain wall panels.

[0027] As a further supplement to the present application, the outer cover of the transmission structure is provided with a protective shell cover, which is fixed to the side end of the fixed sleeve, so that structures such as the first bevel gear, the second bevel gear, the threaded rod, the threaded square sleeve and the return sleeve are not easily corroded.

[0028] As a further supplement to the present application, a sealing block is fixed to the end of the sliding column located inside the fixed sliding sleeve and is slidably fitted with the inner wall of the fixed sliding sleeve, and a tapered hole is provided on the side end of the fixed sliding sleeve away from the sliding column;

[0029] The diameter of the conical hole facing the inner side of the fixed sleeve is larger, a flow control plate is arranged on the inner side of the conical hole, a fixing column is fixed on the inner wall of the conical hole away from the inner side of the fixed sleeve, and an elastic connecting piece is fixed between the fixing column and the flow control plate;

[0030] A limiting guide column that slides through the flow control plate is fixed on the fixed column; through the coordinated arrangement of the tapered hole, the flow control plate and the elastic connecting piece, when the sliding column is pulled outward, the external airflow enters the inner side of the fixed sliding sleeve through the tapered hole, and under the action of the airflow, the elastic connecting piece is stretched by force, at this time, the gap between the flow control plate and the tapered hole becomes larger, the pressure of the airflow inflow is reduced, and the resistance to pulling the sliding column outward is smaller; and when a new curtain wall panel is replaced, when the sliding column is reset with the reset piece, the air on the inner side of the fixed sliding sleeve is squeezed outward with the sealing block, at this time, under the action of the airflow, the elastic connecting piece is compressed by force, at this time, the gap between the flow control plate and the tapered hole becomes smaller, the pressure of the airflow outflow is increased, and the reset resistance to the sliding column is increased, so that the sliding column slowly resets with the curtain wall panel, which plays a buffering role, avoids violent collision when the sliding column resets with the curtain wall panel, which is beneficial to protecting the curtain wall panel.

[0031] In summary, by installing a connecting mechanism including a retractable connecting assembly and an operating assembly between the curtain wall panel and the inherent mounting frame, the suction cup can be directly used to suck the curtain wall panel and pull it outward, so that the retractable connecting assembly is expanded until the limit block passes through the limit through hole. At this time, the curtain wall panel can be stably disassembled and assembled. After replacing a new curtain wall panel, the rotary handle is manually rotated to make the rotating shaft rotate with the first bevel gear, and the first bevel gear drives the second bevel gear to rotate with the threaded rod, and the threaded rod drives the threaded square sleeve to slide in the return sleeve toward the limit block until the threaded square sleeve squeezes the limit block into the groove. At this time, the sliding column pulls the curtain wall panel toward one side of the inherent mounting frame under the action of the reset member until the curtain wall panel and other curtain wall panels are located on the same plane. The operation is more convenient and reliable, and can ensure the integrity of the disassembled curtain wall panel, which is convenient for recycling and reuse, and more energy-saving.

[0052] The side end of the fixed sliding sleeve 311 close to the first mounting plate 312 is provided with an avoidance groove 315 for the limit block 324 to pass through, and the edge of one side of the upper end of the limit block 324 close to the second mounting plate 322 is set to be chamfered; the avoidance groove 315 can allow the limit block 324 to be naturally placed when the curtain wall panel 1 is installed, thereby maintaining the original length of the elastic member 325 and preventing the elasticity from being weakened due to being in a compressed state for a long time, wherein the chamfer on the limit block 324 can prevent the limit block 324 from being limited by the avoidance groove 315.

[0053] Further, such as Figure 4 and Figure 5 As shown, a limiting protrusion 314 is provided on the inner wall of the end of the fixed sleeve 311 away from the first mounting plate 312, and a strip groove 326 is provided at the side end of the sliding column 321 for sliding cooperation with the limiting protrusion 314. The setting of the limiting protrusion 314 can effectively prevent the sliding column 321 from completely separating from the fixed sleeve 311.

[0054] Among them, two retractable connecting components are provided, and the two retractable connecting components are respectively located on the opposite sides of the back side of the curtain wall panel 1, and the operating component 33 is connected between the two fixed sliding sleeves 311; the connection structure is symmetrically installed on the opposite sides of the back side of the curtain wall panel 1 to ensure the stability of its connection.

[0055] Among them, Figure 3 and Figure 5 As shown, the operating assembly 33 includes a rotating shaft 331 and a transmission structure. The rotating shaft 331 is rotatably installed between the two rotating shafts 331. The two ends of the rotating shaft 331 are connected to the two fixed sleeves 311 through the transmission structure. A rotating handle is fixed to one end of the rotating shaft 331.

[0056] Specifically, Figure 3 and Figure 5336 and the return sleeve 337 are shown in the figure. The transmission structure includes a first bevel gear 332, a second bevel gear 334, a threaded rod 335, a threaded square sleeve 336 and a return sleeve 337. The side end of the fixed sleeve 311 is fixed with a fixed frame 333. The first bevel gear 332 is coaxially fixed to the rotating shaft 331. The second bevel gear 334 is coaxially fixed to the threaded rod 335 and meshes with the first bevel gear 332. The threaded rod 335 is rotatably mounted on the fixed frame 333. The threaded square sleeve 336 is threadedly sleeved on the outer side of the threaded rod 335. The return sleeve 337 is fixed to the side end of the fixed sleeve 311 and slidably sleeved on the threaded square sleeve 336. The outer side of the sleeve 336, after replacing the new curtain wall panel 1, manually rotate the handle to make the rotating shaft 331 rotate with the first bevel gear 332, the first bevel gear 332 drives the second bevel gear 334 to rotate with the threaded rod 335, and the threaded rod 335 drives the threaded square sleeve 336 to slide toward the limit block 324 in the return sleeve 337 until the threaded square sleeve 336 squeezes the limit block 324 into the groove 323. At this time, the sliding column 321 pulls the curtain wall panel 1 toward one side of the inherent mounting frame 2 under the action of the reset member 34 until the curtain wall panel 1 is located on the same plane as other curtain wall panels 1.

[0057] Among them, the outer cover of the transmission structure is provided with a protective shell cover (not shown in the figure), which is fixed to the side end of the fixed sleeve 311, so that the first bevel gear 332, the second bevel gear 334, the threaded rod 335, the threaded square sleeve 336 and the return sleeve 337 and other structures are not easily corroded.

[0058] Among them, Fig. 9 and 10 As shown, a sealing block 327 that slides in contact with the inner wall of the fixed sleeve 311 is fixed to the end of the sliding column 321 located on the inner side of the fixed sleeve 311, and a conical hole 316 is provided on the side end of the fixed sleeve 311 away from the sliding column 321. The diameter of the conical hole 316 on the side facing the inner side of the fixed sleeve 311 is larger, and a flow control plate 317 is provided on the inner side of the conical hole 316. A fixing column 318 is fixed on the inner wall of the conical hole 316 away from the inner side of the fixed sleeve 311, an elastic connecting piece 3110 is fixed between the fixing column 318 and the flow control plate 317, and a limiting guide column 319 that slides through the flow control plate 317 is fixed on the fixing column 318.

[0059] By means of the coordinated arrangement of the conical hole 316, the flow control plate 317 and the elastic connecting piece 3110, when the sliding column 321 is pulled outward, the external airflow enters the inner side of the fixed sliding sleeve 311 through the conical hole 316, and under the action of the airflow, the elastic connecting piece 3110 is stretched, at which time the gap between the flow control plate 317 and the conical hole 316 becomes larger, the pressure of the airflow inflow is reduced, and the resistance to pulling the sliding column 321 outward is small; and when a new curtain wall panel is replaced, the sliding column 321 is pulled outward by the reset piece 34. When 321 is reset, the sealing block 327 is used to squeeze out the air inside the fixed sliding sleeve 311. At this time, under the action of the airflow, the elastic connecting piece 3110 is compressed. At this time, the gap between the flow control plate 317 and the tapered hole 316 becomes smaller, the pressure of the airflow outflow increases, and the reset resistance of the sliding column 321 increases, so that the sliding column 321 slowly resets the curtain wall panel, which plays a buffering role, avoids severe impact when the sliding column 321 resets the curtain wall panel, and is beneficial to protecting the curtain wall panel.

[0060] In this solution, by installing a connection mechanism 3 including a telescopic connection component and an operating component 33 between the curtain wall panel 1 and the inherent mounting frame 2, the curtain wall panel 1 can be directly sucked by the suction cup and pulled outwards, such as Figure 8 As shown, the telescopic connection assembly is unfolded until the limit block 324 passes through the limit through hole 313, and the curtain wall panel 1 can be stably disassembled and assembled (in the figure, L1 is the distance between the curtain wall panel 1 and the inherent mounting frame 2 before the curtain wall panel 1 is pulled outward, and L2 is the distance between the curtain wall panel 1 and the inherent mounting frame 2 after the curtain wall panel 1 is pulled outward. The part of L2 that is longer than L1 can be used for the staff to extend their arms to disassemble and assemble the curtain wall panel 1, so that the working space is larger and the disassembly and assembly operation is more convenient). After replacing the new curtain wall panel 1, the rotary handle is manually rotated so that the rotating shaft 331 carries the first bevel gear 332 The first bevel gear 332 drives the second bevel gear 334 to rotate with the threaded rod 335, and the threaded rod 335 drives the threaded square sleeve 336 to slide in the return sleeve 337 toward the limit block 324 until the threaded square sleeve 336 squeezes the limit block 324 into the groove 323. At this time, the sliding column 321 pulls the curtain wall panel 1 toward one side of the inherent mounting frame 2 under the action of the reset member 34 until the curtain wall panel 1 is located on the same plane as other curtain wall panels 1. The operation is more convenient and reliable, and can ensure the integrity of the disassembled curtain wall panel 1, which is convenient for recycling and reuse, and more energy-saving.

[0061] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
