[0040] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0041] like Figure 1-13 As shown, a recyclable energy-saving curtain wall composite panel includes a frame 1 with a strip-shaped depression on the end surface, and also includes a wall panel 2 composed of a panel layer 201, a core material layer 202, and a back panel layer 203, and a rubber strip 3 is arranged between adjacent wall panels 2, and the wall panel 2 is also provided with a board leg 21 installed in the depression of the frame 1;

[0042] The concave end of the frame 1 is provided with a concave section 43, in which a supporting member 4 is arranged to abut against the wall panel 2, and the supporting member 4 is divided into an arc strip 41 and flat strips 42 symmetrically arranged on both sides of the arc strip 41 according to the shape;

[0043] A butt joint 5 is slidably provided at the end of the arc strip 41, and a pointed head 51 is provided at the end of the butt joint 5. Four adjacent pointed heads 51 abut against each other and are used to cooperate with the intersection of the four rubber strips 3. An elastic member 53 is provided at the end surface of the butt joint 5, and a pressure strip 54 fixed to the plate leg 21 is provided at the end of the elastic member 53.

[0044] It also includes a screw member 6 threadedly connected to the recess of the frame 1 , and a pressing plate 65 for pressing and fixing the plate legs 21 is arranged on the screw member 6 .

[0045] Specifically, the frame 1 is installed on the wall at the arc by connecting with bolts or expansion screws. The panel layer 201 is made of aluminum alloy, stainless steel, titanium zinc alloy and the like, and has high strength, good weather resistance and corrosion resistance. The core layer 202 mostly uses lightweight and high-strength materials, such as aluminum honeycomb, hard foam plastic (such as polyurethane), inorganic mineral board, etc., which not only have good heat insulation and sound insulation properties, but also can effectively disperse and resist external forces, thereby improving the bending resistance of the composite board. The back panel layer 203 is usually made of the same material or similar metal material as the panel layer 201, such as aluminum alloy, stainless steel, etc., and the pores of the core layer 202 can effectively fit with the rubber strip 3 to improve the waterproof sealing effect.

[0046] Furthermore, the rubber strip 3 is a strip of rubber in the prior art, which will not be elaborated here. The board leg 21 is fixed to the back plate layer 203 by screws and is in an "L" shape. A hole is opened on it for cooperating with screws and gaskets to fix it in the recess of the frame 1, thereby improving the force and stability of the board leg 21.

[0047] Furthermore, the length of the concave section 43 is smaller than the distance between the two board legs 21 on one side of the wall panel 2, so that the support member 4 after installation does not affect the disassembly and assembly of the wall panel 2. The arc strip 41 is made of elastic metal sheet and is used to buffer the force transmitted from the outside, and the arc strip 41 under deformation also moves in the concave section 43.

[0048] Furthermore, a rounded rectangular hole is provided on the arc bar 41, and a semicircular recess is provided at one end of the hole of the docking piece 5, so that a tool can be manually inserted into the rounded rectangular hole, and then the semicircular recess can be pushed horizontally to drive the docking piece 5 to extend from the end of the arc bar 41, so that the parts on the docking piece 5 can be used to press the plate leg 21.

[0049] Furthermore, the pointed head 51 is at the end of the docking piece 5 that extends out, and the end of the pointed head 51 is at an angle of 45°, and the end of the pointed head 51 is in a raised state; the rubber strip 3 is provided with a sealing opening embedded in the end of the screw member 6, that is, a circular channel, and the sealing port communicating with the outside world is installed with a rubber membrane flap to shield and protect the end of the screw member 6.

[0050] Furthermore, the elastic member 53 is specifically a conical spring, and the pressure strip 54 is located at the larger end surface of the cone, so that the elastic member 53 can have a larger contact surface with the strip-shaped pressure strip 54 to ensure the deformation effect of the elastic member 53.

[0051] The arc strips 41 of the supporting member 4 are first placed in the concave sections 43 of the frame 1, and then the wall panels 2 on both sides of the frame 1 are installed so that the board legs 21 are fixed in the concave sections 43 of the frame 1, and at the same time, the flat strips 42 on both sides of the arc strips 41 are fitted and abutted against the back panel layer 203, so that after the wall panels 2 on both sides of the frame 1 are impacted by external force, the force can be transmitted to the two flat strips 42, and buffered by the elastic arc strips 41 to reduce the excessive force on the frame 1 at this position, and also reduce the problem of loosening of the screws on the board legs 21, and then manually push out the docking member 5, and stop when the pointed head 51 reaches the cross position of the frame 1, so that the ends of the four pointed heads 51 close to each other at this position abut against each other to form a raised barrier, effectively improving the connection effect of the supporting member 4, and accompanied by the elastic member 53 with the pressure strip 54 arriving at the position of the board leg 21, the pressure strip 54 abuts against the screw cap on the board leg 21, thereby providing an auxiliary pressing effect for the installation of the wall panel 2, and at the same time, the arc strips The force received by 41 can be transmitted to the elastic member 53. On the one hand, it is absorbed by the elastic member 53 to buffer and reduce the transmission of external force. On the other hand, the elastic member 53 after storing force can also press the screw, that is, after the wall panel 2 is subjected to external force in windy weather, the elastic member 53 can enhance the connection stability of the board leg 21, and then the screw member 6 is screwed into the depression of the frame 1 to make the pressure plate 65 press the installed board leg 21, further enhance the installation stability of the wall panel 2, and greatly reduce the problem of damage or even falling of the wall panel 2. Finally, the rubber strip 3 is inserted into the gap between the two wall panels 2, so that the screw member 6 is embedded in the seal on the rubber strip 3, so that the rubber membrane petal in the seal protects the screw member 6, and the screw member 6 can be directly operated to move later. At the same time, after the rubber strip 3 is encapsulated, glue is filled and sealed at the cross position, so that the solidified glue is matched with the raised barrier to have better waterproof and pressure resistance effect, thereby improving the overall beauty of the wall panel 2, stronger stability and pressure resistance.

[0052] As an embodiment further provided by the present invention, the screw member 6 is divided into a middle shaft 61, a lower screw shaft 62 and an upper shaft 63 according to function, and the end of the lower screw shaft 62 is threadedly connected to the recess of the frame 1.

[0053] Specifically, a thread is opened at the end of the lower screw shaft 62, a screw hole for connecting the lower screw shaft 62 is opened on the recessed upper part of the skeleton 1, and a nut is fixedly installed at the end of the upper shaft 63 (the nut is fitted with a sealed rubber membrane petal) so that the upper shaft 63 can be rotated using a screwdriver.

[0054] Furthermore, the pressing plate 65 is a rounded rectangular plate formed by symmetrically cutting a circular plate, so that after the pressing plate 65 is rotated 90°, the distance formed by its cutting notch is smaller than the distance between the plate legs 21 of two wall panels 2 arranged relatively to each other, thereby achieving that the pressing plate 65 does not affect the disassembly and assembly of a single wall panel 2.

[0055] By rotating the upper shaft 63, the lower screw shaft 62 is threadedly connected to the depression of the frame 1, so that the screw member 6 can be directly and firmly connected to the frame 1, and the pressing plate 65 can stably press the plate leg 21 under the action of the thread to prevent the plate leg 21 from loosening during operation.

[0056] As another embodiment further provided by the present invention, a through hole 50 is provided on the docking member 5 for the screw member 6 to move, and a plug plate 66 is fixedly sleeved on the central axis 61 and abutted against the through hole 50 .

[0057] Specifically, the diameter of the through hole 50 is larger than the diameter of the pressure plate 65 , the cross section of the plug plate 66 is a stacked circular plate, and the folds at the stacking position are fixedly installed with a rubber ring.

[0058] Furthermore, a long hole is opened on the docking member 5, and a tension spring is fixedly installed in the hole. The other end of the tension spring is fixedly installed at the end of the arc bar 41, and the docking member 5 does not separate from the arc bar 41 after sliding, so that the tension spring provides a pulling force for the docking member 5 to reset.

[0059] Before the threaded connection, the pressure plate 65 is passed through the through-hole 50 by the lower screw shaft 62 of the screw member 6, and when the threaded connection is made, the fold position on the plug plate 66 is fitted into the port of the through-hole 50, so that the rubber ring limits the through-hole 50 and stabilizes the connection, so that the manually pulled-out docking member 5 is restricted to the current extended state, and the docking member 5 can only move toward the board leg 21, so as to ensure that the elastic member 53 can stably perform the buffering and pressing work of the board leg 21, and at the same time, it can also enable the supporting member 4 to stably fill the gap between the two wall panels 2 and perform the buffering work.

[0060] As another embodiment further provided by the present invention, an arc groove 7 covered by a pressure plate 65 is formed on the plate leg 21 , and the pressure plate 65 is fixedly sleeved on the central axis 61 .

[0061] Specifically, the spacing formed by the uncut circular portion of the pressing plate 65 is larger than the spacing between the arc grooves 7 on the two oppositely arranged plate legs 21 , so that the pressing plate 65 can press and fix the plate legs 21 on the two wall panels 2 .

[0062] By rotating the upper shaft 63, the middle shaft 61 is synchronously driven to rotate, so that the pressure plate 65 on the middle shaft 61 is horizontally blocked on the plate leg 21 of the arc groove 7, and the arc groove 7 provides a larger range of motion for the pressure plate 65 after rotating 90°, that is, when a single wall panel 2 is disassembled and assembled, the plate leg 21 of the wall panel 2 has a larger disassembly area, which makes the disassembly and assembly of the wall panel 2 smoother, reduces the work cycle of maintenance personnel, and reduces the occurrence of dangerous situations.

[0063] As another embodiment further provided by the present invention, a guide rod 55 inserted into the docking piece 5 is vertically movably provided on the pressure strip 54 , a pit 56 is provided on the plate leg 21 , and a rod head 551 embedded in the pit 56 is provided on the guide rod 55 .

[0064] Specifically, a hole is opened on the pressure strip 54 for the guide rod 55 to move, a ring sleeve is fixedly provided on the guide rod 55, and a tension spring is fixedly installed between the ring sleeve and the pressure strip 54.

[0065] Furthermore, the rod head 551 is rounded at the end of the guide rod 55 so that the rod head 551 can slide into the pit 56 when it is pushed to a predetermined position, and the pit 56 and the edges of the arc groove 7 are rounded so that the rod head 551 can slide out smoothly through the arc groove 7.

[0066] Furthermore, an arc-shaped groove is formed on the docking member 5 for the guide rod 55 to move, and two symmetrically arranged arc-shaped grooves are parts of a whole circular groove.

[0067] The pressure strip 54 reaches the predetermined position, presses the screw nut on the plate leg 21, and makes the rod head 551 slide into the pit 56 to achieve positioning, accompanied by the tension spring on the guide rod 55 to restore the deformation. When the docking member 5 moves vertically with the deformation of the arc bar 41, the guide rod 55 provides guidance and limiting purposes for the docking member 5, so that the docking member 5 is more stable during vertical movement, and avoids the docking member 5 from swinging and affecting the buffering work of the arc bar 41.

[0068] As another embodiment further provided by the present invention, a disc 52 is rotatably provided on the docking member 5, and an elastic member 53 is fixedly installed on the end surface of the disc 52;

[0069] An eccentric plate 67 is fixedly sleeved on the central shaft 61 , and a forked member 521 is fixedly mounted on the disc 52 to contact and slide with the eccentric plate 67 .

[0070] Specifically, a torsion spring is provided at the rotation position of the disc 52 , and in a default state, the torsion spring enables the pressure strip 54 to be arranged vertically with the gasket on the plate leg 21 .

[0071] Furthermore, the eccentric plate 67 is an eccentric component formed by a combination of a large circle and a small circle, and the curvature of the arc surface on the fork member 521 is greater than the curvature of the large circle on the eccentric plate 67, but the arc surface where the large circle of the eccentric plate 67 switches to the small circle is consistent with the arc surface of the fork member 521, and a rubber pad is fixedly installed on the arc surface of the fork member 521.

[0072] After the plug plate 66 fits the through hole 50, the large circle position on the eccentric plate 67 contacts the arc surface of the forked piece 521, and the end faces of the two are on the same horizontal plane. During the vertical movement of the docking piece 5, the forked piece 521 on the disc 52 is prompted to continuously slide in contact with the eccentric plate 67, so that under the damping action provided by the rubber pad, the vertically movable docking piece 5 will not shake repeatedly, thereby ensuring the pressure of the elastic piece 53 on the plate leg 21 and the stability of the buffering work of the arc strip 41.

[0073] As another embodiment further provided by the present invention, a square rod 64 is fixedly installed on the upper shaft 63 and is plugged and movably connected to the middle shaft 61. A round rod 641 is fixedly installed on the end of the square rod 64 and is plugged and movably connected to the lower screw shaft 62.

[0074] The round rod 641 is fixedly mounted with sliding blocks 642 which are symmetrically arranged, and the sliding blocks 642 are located between the middle shaft 61 and the lower screw shaft 62 .

[0075] Specifically, a circular depression is formed at the end of the middle shaft 61 , and a columnar spring is fixedly installed between the end of the upper shaft 63 and the circular depression. The cross section of the square rod 64 is square, so that the square rod 64 provides a rotation synchronization effect between the middle shaft 61 and the upper shaft 63 .

[0076] Furthermore, the lower screw shaft 62 is rotationally connected to the middle shaft 61 , and the slider 642 is a strip-shaped block, which is convenient for connecting the middle shaft 61 and the lower screw shaft 62 .

[0077] When the columnar spring is not compressed, the square rod 64 keeps the upper shaft 63 and the middle shaft 61 rotating synchronously, and the slider 642 at this time provides a synchronous connection between the middle shaft 61 and the lower screw shaft 62, so that during the rotation of the upper shaft 63, the lower screw shaft 62 is threadedly connected to the recess of the skeleton 1, thereby enhancing the installation effect of the screw member 6 on the supporting member 4 and being more convenient to use.

[0078] As another embodiment further provided by the present invention, a docking channel 643 is provided on the lower screw shaft 62 for the sliding block 642 to slide and receive, and is used to decouple the middle shaft 61 so that the middle shaft 61 can rotate on the lower screw shaft 62 .

[0079] Specifically, the lower screw shaft 62 is further provided with a sector-shaped channel 644 centered on the docking channel 643 and arranged symmetrically, and the sector-shaped channel 644 is provided with a clamping hole 645 recessed toward the central axis 61 .

[0080] When disassembling the damaged wall panel 2, the four rubber strips 3 around it need to be removed. Before that, use a screwdriver to insert into the nut at the end of the upper shaft 63 and then press it to make the round rod 641 send the slider 642 to the end of the docking channel 643, that is, the two fan-shaped channel 644 ports, so that the slider 642 decouples the center axis 61 and the lower screw shaft 62, so that the center axis 61 can rotate on the lower screw shaft 62 fixed by threads, and then the square rod 64 is used to drive the pressure plate 65 on the center axis 61 to rotate 90°, so that the pressure plate 65 releases the horizontal arc groove 7, which is used to unlock the board leg 21, and the pressure plate 65 can complete the unlocking work by using the forward or reverse rotation, and the actual operation is simpler.

[0081] As another embodiment further provided by the present invention, a deep groove 71 is formed on the arc groove 7, and the pressure strip 54 approaches the deep groove 71 as the distance between the eccentric plate 67 and the disc 52 decreases in the rotating state;

[0082] A trigger block 671 is fixedly mounted on the eccentric plate 67 , and the trigger block 671 is coupled to the forked member 521 , so that the disc 52 drives one end of the pressure strip 54 to be embedded in the deep groove 71 and the other end to abut against the plate leg 21 .

[0083] Specifically, the distance between the inner walls of the arc-shaped deep grooves 71 on the oppositely arranged plate legs 21 is greater than the length of the pressure strip 54, and the diameter of the deep groove 71 is greater than the position of the pressure strip 54 after deflection, and the end of the pressure strip 54 is close to one side of the width of the deep groove 71 on a single plate leg 21 (such as Fig.13 The position shown in the figure) is used to allow the pressure strip 54 to have a larger range of motion.

[0084] By adopting the forward or reverse rotation mode, the arc surface of the eccentric plate 67 switching from the large circle to the small circle is made to fit the arc surface of the fork piece 521, and the fork piece 521 is gradually brought close to the axis of the central axis 61 during the switching process, so that the pressure strip 54 is away from the screw on the plate leg 21, and the rod head 551 slides out of the pit 56 until it reaches the deep groove 71. At this time, the trigger block 671 abuts against the outer side of the fork piece 521 and forms a single tooth-shaped meshing transmission to drive the disc 52 to rotate, so that one end of the rotating pressure strip 54 is still in the deep groove 71. The tension spring on the guide rod 55 at that location restores its deformation, and the other end of the pressure strip 54 slides onto the board leg 21 again, so that the tension spring on the guide rod 55 at that location remains deformed. The purpose is that the wall panel 2 that does not need to be disassembled is still pressed and fixed to the board leg 21 by the pressure strip 54, while the wall panel 2 that needs to be disassembled loses the pressure of the pressure plate 65 and the pressure strip 54 at the same time, which is convenient for disassembly and assembly of the wall panel 2. Moreover, when rotating the upper shaft 63, it is only necessary to turn the rotation direction toward the wall panel 2 that does not need to be disassembled, which makes the disassembly and assembly steps simpler and makes the disassembly process of the wall panel 2 smoother.

[0085] As another embodiment further provided by the present invention, the pressure strip 54 in the interference state enables the rod head 551 to slip out of the pit 56 and is used to enable the guide rod 55 to move vertically.

[0086] Specifically, the end of the guide rod 55 in a default state contacts the back of the rubber strip 3 , so that the rubber strip 3 has a limiting function during installation, thereby increasing the accuracy of the installation of the rubber strip 3 .

[0087] The other end of the pressure strip 54 slides onto the board leg 21 again, so that the tension spring on the guide rod 55 remains deformed, so as to make the guide rod 55 extend beyond the original position and to lift the back side of the rubber strip 3 at the guide rod 55, so that the edge of the rubber strip 3 forms a bulge relative to the surface of the wall panel 2, which is convenient for maintenance personnel to have a force point to peel off the rubber strip 3. Compared with using tools to directly lift the rubber strip 3, the damage to the rubber strip 3 can be reduced, thereby ensuring the integrity of the rubber strip 3 and realizing the recyclable use of the rubber strip 3.

[0088] Working principle: by placing the arc strip 41 of the supporting member 4 in the concave section 43 of the frame 1, and then installing the wall panels 2 on both sides of the frame 1, so that the board legs 21 are fixed in the concave section 43 of the frame 1, and at the same time, the flat strips 42 on both sides of the arc strip 41 are fitted and abutted against the back plate layer 203, so that after the wall panels 2 on both sides of the frame 1 are impacted by external force, the force can be transmitted to the two flat strips 42 and buffered by the elastic arc strip 41, and then manually push out the docking member 5, and stop when the pointed head 51 reaches the cross position of the frame 1, so that the ends of the four pointed heads 51 close to each other at this position abut against each other to form a raised barrier, which effectively improves the connection effect of the supporting member 4, and the elastic member 53 with the pressure strip 54 reaches the position of the board leg 21, so that the pressure strip 54 abuts against the screw cap on the board leg 21, thereby providing an auxiliary pressing effect for the installation of the wall panel 2. At the same time, the force received by the arc strip 41 can be transmitted to the elastic member 53. On the one hand, it is absorbed by the elastic member 53 to buffer and reduce the transmission of external force. On the other hand, the elastic member 53 after storing force can also press the screw, that is, after the wall panel 2 is subjected to external force in windy weather, the elastic member 53 can enhance the connection stability of the board leg 21, and then the screw member 6 is screwed into the recess of the frame 1 to enable the pressure plate 65 to press the installed board leg 21, further enhancing the installation stability of the wall panel 2, and finally the rubber strip 3 is inserted into the gap between the two wall panels 2, so that the screw member 6 is embedded in the seal on the rubber strip 3, so that the rubber membrane petal in the seal protects the screw member 6, and the screw member 6 can be directly operated to move later. At the same time, after the rubber strip 3 is encapsulated, glue is filled in the cross position to seal it, so that the solidified glue is matched with the raised barrier to have better waterproof and pressure resistance effect.

[0089] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
