Technical Field

[0002] For aesthetic purposes, various exterior materials are applied to the surface of building walls; this is called a curtain wall. A stone curtain wall consists of structural supports, panels, and a hanging system. The hanging system consists of connectors that attach the panels to the structural supports. Components fixed to angle steel are called base hangers, while components fixed to the stone and hung on these base components are called subordinate components. Together, they constitute the stone hanging system, working together to achieve the vertical installation of the stone. However, existing curtain wall stone hanging systems still have the following drawbacks during assembly.

[0003] Firstly, mechanical drilling is required to install the basic hangers at the center of the stone curtain wall. However, it is not easy to quickly find the center point when drilling. If there is an error in drilling, the basic hangers cannot be properly assembled with the structural support connectors, which affects work efficiency.

Detailed Implementation

[0048] In the description of this invention, it should be understood that the terms "length," "width," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention. The various embodiments of this invention are described in detail below with reference to the accompanying drawings.

[0049] Example 1

[0050] Please see Figures 1 to 16 The present invention preferably provides the following technical solution: a curtain wall stone hanging component assembly system, comprising: a system assembly frame, and a plurality of stone hanging component bodies installed with the system assembly frame; the system assembly frame is composed of a plurality of assembly frames 111, and limiting assembly strip assemblies disposed on the periphery of the assembly frames 111; it also includes a central extension frame assembly, which is disposed on the assembly frames 111 and acts on the limiting assembly strip assemblies; and an extension pin structure connected to the central extension frame assembly, the bottom of the extension pin structure being provided with a color marking head 5111; the stone hanging component body includes a stone plate 211, and assembly holes 2111 disposed on the stone plate 211, the outer periphery of the assembly holes 2111 being provided with mounting... Step section 2112; when the central extension frame assembly is in operation and pre-acting on the limiting assembly strip assembly, the extension pin structure is at the center of the assembly frame 111. When the stone pendant body is pre-assembled with the assembly frame 111, the color marking head 5111 can be used to mark the center of the stone pendant body to determine the center hole position of the assembly hole 2111. When the stone pendant body is finally assembled with the assembly frame 111, the extension pin structure enters the assembly hole 2111 to complete the expansion and support and fix it. And the end locking assembly is set at the ends of the central extension frame assembly. When the end locking assembly is in operation, it can be snapped into the limiting assembly strip assembly on the assembly frame 111 to complete the assembly process of the stone pendant body and the system assembly frame.

[0051] This application designs an innovative curtain wall stone cladding assembly system, whose assembly frame consists of several assembly frames 111, specifically, as follows: Figure 1 , 2 As shown in Figures 4 and 5, under the expansion action of the central extension frame assembly, the assembly process of the limiting assembly strip assembly further provided on the assembly frame 111 consists of two processes:

[0052] S1: Pre-assemble and determine the center position of the assembly hole 2111 of the stone hanger body: When the center extension frame assembly contacts the limiting assembly strip assembly in both the horizontal and vertical directions, the position of the corresponding extension pin structure is the center of the stone hanger body. Figure 4 As shown, the color marking head 5111 at the bottom of the extension pin structure can be used for center marking of the stone pendant body to facilitate the subsequent drilling steps, thereby determining the center hole position of the assembly hole 2111.

[0053] S2: Assemble the stone pendant onto the system assembly frame: (e.g.) Figures 2 to 1 In this state, the stone plate 211 of the stone pendant body is placed inside the frame of the assembly frame 111. At this time, the assembly hole 2111 where the stone plate 211 is located is directly below the expansion pin structure. At this time, the expansion pin structure is driven to run, so that its end enters the assembly hole 2111 for pre-fixation during assembly, that is, the fixing of the central expansion frame assembly and the stone pendant body is completed.

[0054] S3: Then, the central extension frame assembly is processed again. The end locking components at its four ends can be snapped together with the limiting assembly strip components on the assembly frame 111, thus realizing the final assembly process of the stone pendant body and the system assembly frame.

[0055] Furthermore, the central extension frame assembly includes a frame base, which consists of a first support frame 812 and a second support frame 813 at the top and bottom, and a connecting frame 811 connected to the side walls of the two. The first support frame 812 and the second support frame 813 are provided with through holes in the middle for through assembly of the extension pin structure. The first engagement extension component and the second engagement extension component are respectively provided at the top and bottom of the first support frame 812 and the second support frame 813. The first engagement extension component and the second engagement extension component have the same structure and are vertically distributed. The first insertion post component and the second insertion post component are provided at the top and bottom of the connecting frame 811. The first insertion post component and the second insertion post component have the same structure and are respectively used for locking the positions of the first engagement extension component and the second engagement extension component.

[0056] Through further configuration of the central expansion frame structure, such as Figure 1 , 6As shown in Figures 7 and 9, under the action of the first engaging expansion component, it can perform forward and backward engaging expansion until it contacts the edge sidewall of the limiting assembly strip component. Through the action of the first insert component, the expansion state of the first engaging expansion component can be locked. Similarly, under the action of the second engaging expansion component, it can perform left and right engaging expansion. Through the action of the second insert component, the expansion state of the second engaging expansion component can be locked. When the first engaging expansion component and the second engaging expansion component complete the expansion and act on the edge sidewall of the limiting assembly strip component, the frame base can be located at the center position of the assembly frame 111, that is, the center position of the corresponding stone hanging body.

[0057] Furthermore, the first engagement extension assembly includes a rotatable outer toothed ring 911 mounted on the bottom of the first support frame 812, and expansion bars 912 that are slidably positioned opposite each other on the first support frame 812. The opposing surfaces of the two expansion bars 912 are each provided with a second rack 913 that engages and drives the outer toothed ring 911. The assembly also includes a rotating disk 312 acting on the upper surface of the outer toothed ring 911. The rotating disk 312 extends to the outside of the frame base and is provided with a ring 3122. The ring 3122 is provided with a plurality of limiting holes 3121 distributed in a ring, and a handle block 3123 provided on the outer wall of the rotating disk 312.

[0058] like Figure 6 , 7 As shown, since the first meshing expansion assembly and the second meshing expansion assembly have the same structure, only the first meshing expansion assembly will be described here. When the external toothed ring 911 rotates, it meshes with the second toothed racks 913 on both sides. When it rotates, it can drive the expansion bars 912 on both sides to separate or move relative to each other. Since they move synchronously to both sides, when the ends of the expansion bars 912 on both sides act on the limiting assembly bar assembly, the frame seat can be located at the midpoint of the front-back direction of the assembly frame 111. Similarly, when the second meshing expansion assembly runs and acts on the limiting assembly bar assembly, the frame seat can be located at the midpoint of the left-right direction of the assembly frame 111, that is, the frame seat is placed at the center of the assembly frame 111.

[0059] like Figure 6 and 15 The setting is further configured by rotating disk 312, with its inner downward-extending ring connected to the outer toothed ring 911. Through several handle blocks 3123 on the outer downward-extending ring, when rotating disk 312 is rotated, the outer toothed ring 911 can be driven to rotate, thereby driving the expansion support bars 912 on both sides to expand.

[0060] Furthermore, the first insertion post assembly includes a sleeve 713, a telescopic plug 711 that moves telescopically with the sleeve 713, the end of the telescopic plug 711 being adapted to be inserted into the limiting hole 3121, and a handle ring 712 fixed on the telescopic plug 711, with a second compression spring 714 wound around the outer wall of the telescopic plug 711 between the handle ring 712 and the sleeve 713.

[0061] With further modifications to the first and second insert components, since their structural principles are the same, only the first insert component will be described here, such as... Figure 1 , 9 As shown, pressing the handle ring 712 moves it closer to the sleeve 713, causing the telescopic plug 711 to disengage from the limiting hole 3121 on the ring 3122 and compress the second compression spring 714, thus unlocking the position of the rotating disk 312. After the rotating disk 312 has finished rotating, releasing the handle ring 712 causes the end of the telescopic plug 711 to re-insert into the limiting hole 3121, thus locking the position of the rotating disk 312.

[0062] Example 2

[0063] In another embodiment of the present invention, the extension pin structure includes a support cylinder 511, which passes through the inner wall of a through hole fixed to the second support frame 813 by a connector, and grooves distributed in an annular pattern on the outer wall of the support cylinder 511. Each groove is provided with a connecting rod extension block frame. Each set of connecting rod extension block frames includes a transmission bar 514 that can move up and down and is installed in the groove. The bottom of the transmission bar 514 is connected to a first slot frame 519. It also includes an expansion block 521 with a wedge-shaped cross section. A second slot frame 520 is fixed on the inner wall of the expansion block 521. The upper and lower parts of the second slot frame 520 and the first slot frame 519 are connected by two connecting rods 522 through pins. The two connecting rods 522, the first slot frame 519, and the second slot frame 520 form a quadrilateral structure. It also includes a drive frame assembly provided on the transmission bar 514 for driving the transmission bar 514 to move up and down in the groove. The number of connecting rod extension block frames is eight.

[0064] In this embodiment, an extension pin structure is provided, namely, a plurality of connecting rod extension block frames arranged in a ring on the support cylinder 511, preferably in eight sets, specifically, as shown below. Figure 2 , 7 As shown in Figure 11, in Embodiment 1, the center mark of the stone pendant body can be determined by the structural characteristics of the center extension frame assembly, so as to facilitate the subsequent drilling step to form the assembly hole 2111. The cross section of the assembly hole 2111 is preferably wedge-shaped, which is the same as the cross section shape of the expansion block 521.

[0065] Specifically, during the expansion action, when the expansion pin structure enters the assembly hole 2111 and abuts against its inner bottom, the drive transmission bar 514 moves downward within the groove of the support cylinder 511, and the retracted expansion block 521 abuts against the inner bottom of the assembly hole 2111, as shown. Figure 11 As shown, under the action of the two connecting rods 522 at the top and bottom and the first groove frame 519 and the second groove frame 520 on both sides forming a quadrilateral, when the transmission bar 514 is pressed down, the quadrilateral structure formed by the connecting rods 522 gradually expands until the connecting rods 522 become completely horizontal. At this time, the outer contour of the expansion block 521 fits against the inner wall of the assembly hole 2111, realizing the inner support limit fixation, and the center installation of the expansion pin structure and the stone hanging body can be completed.

[0066] Implementation 3

[0067] In another embodiment of the present invention, the drive frame assembly includes a first ring frame 513, which has a cross structure and its cross ends act on the top of the transmission bars 514 where the four sets of connecting rod extension blocks are located, and a movable column 516 fixed in the middle of the first ring frame 513. A second ring frame 515 that moves up and down is mounted on the movable column 516. The bottom edge of the second ring frame 515 is fixedly connected to the top of the other four sets of transmission bars 514 through a connecting block 512, and a top block 518 is provided on the top of the movable column 516. A first compression spring 517 is connected to the outer wall of the movable column 516 between the top block 518 and the second ring frame 515.

[0068] Through further provided drive frame components, such as Figure 11 As shown, the preferred number of linkage extension block frames is eight. When the drive frame assembly acts intermittently on the eight linkage extension block frames, specifically, as shown... Figure 11 As shown, the first ring frame 513 acts on the top of the transmission bar 514 where the four sets of connecting rod extension blocks are located, and the second ring frame 515 acts on the top of the transmission bar 514 where the other four sets of connecting rod extension blocks are located. In the initial state, the transmission bar 514 where the first ring frame 513 is located is higher than the transmission bar 514 where the connecting block 512 is located. During operation, the top block 518 presses down. Since the movable column 516 passes through the second ring frame 515, under the action of the first compression spring 517, the second ring frame 515 and the first ring frame 513 move downward together. The four sets of expansion blocks 521 where the connecting block 512 is located first abut against the bottom of the assembly hole 2111 and expand to achieve pre-fixation. When it is completely attached to the wall of the assembly hole 2111, the transmission bar 514 where the connecting block 512 is located no longer moves down, and the corresponding top block 518 continues to move down, thereby driving the other four sets of transmission bars 514 to move down and expand, so as to achieve the final complete assembly and locking with the wall of the assembly hole 2111.

[0069] Furthermore, it also includes a support sleeve 616 fixedly connected to the bottom of the first support frame 812, and a mounting member 612 disposed on the top of the support sleeve 616. A rotatable mounting shaft 613 is mounted on the mounting member 612, along with a gear 614 fixed to the middle of the mounting shaft 613, and a first rack 611 that passes through the top of the support sleeve 616 and slides up and down. The first rack 611 meshes with the gear 614 for transmission. One end of the mounting shaft 613 passes through the mounting member 612 and is connected to a crank handle 615. A one-way ratchet assembly is provided between the other end and the mounting member 612 for one-way locking when the first rack 611 descends; further, the one-way ratchet assembly includes a ratchet 619 fixed on the side wall of the mounting member 612, and a mounting ring 620 provided on the inner side of the ratchet 619. The outer wall of the mounting ring 620 is provided with a deflectable ratchet block 617 through a pin. The ratchet block 617 is adapted to the rocker handle 615, and a spline groove 618 is opened on the mounting shaft 613. The spline groove 618 is splinedly connected to the mounting ring 620.

[0070] In this structure, as an implementation method for driving the top block 518 to rise and fall, such as Figure 6 , 7 As shown in Figure 8, when the crank handle 615 is manually turned, the gear 614 will rotate. Figure 8 In the process, when the top of the gear 614 rotates toward the first rack 611, it can drive the first rack 611 to move downward, thereby realizing the downward movement of the drive frame assembly and thus realizing the expansion of the expansion block 521.

[0071] Combination Figure 10 By setting the direction of the unidirectional ratchet assembly, that is, when the top of the gear 614 rotates towards the first rack 611, the unidirectional ratchet locking is achieved through the cooperation of the ratchet block 617 and the ratchet 619. This is a mature existing technology, which will not be elaborated here. This enables the unidirectional step-by-step feed rotation of the mounting shaft 613 and unidirectional self-locking. As the first rack 611 moves downward, it descends step-by-step, which is beneficial for the drive frame assembly to effectively expand the support block 521. With the spline setting of the mounting ring 620 and the spline groove 618, when the support sleeve 616 moves towards the gear 614, the unidirectional ratchet is unlocked, that is, the unlocking process of the expansion pin structure is realized.

[0073] In another embodiment of the present invention, each set of end-locking assemblies includes an extension frame 1011, which is fixedly connected to the end of the expansion bar 912. The extension frame 1011 has an L-shaped structure. A mounting frame 1020 is disposed in the transverse section of the extension frame 1011. The extension frame 1011 passes through the upper part of the mounting frame 1020 and is provided with an end piece 1012. A first tension spring 1019 is disposed between the end piece 1012 and the mounting frame 1020. Two sets of end-locking assemblies are disposed within the mounting frame 1020. Each set of end-locking assemblies includes a movable frame 1018, which is slidably mounted inside the mounting frame 1020. A protrusion 1025 is fixed to its bottom. A second tension spring 1024 connects the protrusion 1025 and the mounting frame 1020. The movable frame 1018 is fixed to the second tension spring 1024. The inner support block 1021 has a latch head installed on the inner wall of the movable frame 1018 in front of the support block 1021 via a pin. The latch head includes a latch body 1013, and a first latch part 1014 and a second latch part 1015 located at the upper and lower ends of the latch body 1013. A rectangular groove 1023 is provided on the side wall of the support block 1021 near the latch head. A fourth spring 1022 is provided inside the rectangular groove 1023. The end of the fourth spring 1022 away from the support block 1021 abuts against the arc surface of the latch body 1013. There are also two crossbars 1017 penetrating the end of the mounting frame 1020. One end of the two crossbars 1017 acts on the support block 1021, and the other end is horizontally connected to a connecting plate 1016. One side of the connecting plate 1016 is fixed to the extension frame 1011.

[0074] And an edge end block 1026 installed on the end of the mounting frame 1020 away from the connecting plate 1016, for abutting against the inner wall of the limiting strip 112;

[0075] Furthermore, the limiting assembly strip assembly includes two sets of opposing limiting strips 112, which are respectively placed on the edge of the assembly frame 111. Each set of limiting strips 112 has a step portion on its inner side. A first assembly groove 113 is opened on the horizontal section of the step portion for fastening the first locking part 1014, and a second assembly groove 114 is opened on the vertical section of the step portion for fastening the second locking part 1015. The height of the second assembly groove 114 is greater than the thickness of the second locking part 1015.

[0076] By setting the end latching components, such as Figure 1 , 2 As shown in 1, 3, 12 and 13, it has two implementation methods:

[0077] One method is to pre-assemble and determine the center position of the assembly hole 2111 of the stone hanging body. Since the edge end block 1026 is installed at the end of the mounting frame 1020 away from the connecting plate 1016, under the action of the fourth spring 1022, when the end locking components of the four ends of the center extension frame assembly all act on the limiting assembly strip assembly, that is, when the center extension frame assembly expands and the edge end block 1026 contacts the inner wall of the limiting strip plate 112, the frame base is located at the center position of the assembly frame 111, that is, the center hole position of the corresponding assembly hole 2111.

[0078] Another method is to assemble the stone pendant body onto the system assembly frame: After completing the assembly hole 2111 in the center hole of the stone slab 211, assemble the stone slab 211 with the assembly frame 111. Under the action of the expansion pin structure, the central expansion frame assembly and the stone pendant body are fixed. Then, run the central expansion frame assembly again, and the end locking components at its four ends can be snapped together with the limiting assembly strip components on the assembly frame 111, thus realizing the final assembly process of the stone pendant body and the system assembly frame.

[0079] Specifically, such as Figure 1 , 2 As shown in 12 and 13, after the edge end block 1026 abuts against the side wall of the limiting strip 112, the central extension frame assembly continues to extend, thereby causing the extension frame 1011 to move relative to the mounting frame 1020 and stretch the first tension spring 1019 at its end. At this time, the connecting plate 1016 is further moved towards the mounting frame 1020, further causing the crossbar 1017 to push the movable frame 1018 where the support block 1021 is located to extend forward together. Due to the structure of the latch head, the end of the fourth spring 1022 away from the support block 1021 abuts against the arc surface of the latch body 1013, as shown in 12 and 13. Figure 1 , 13 As shown, combined with the structural arrangement of the limiting strip 112, and the first assembly groove 113 and the second assembly groove 114, when the support block 1021 and the movable frame 1018 extend forward and approach the limiting strip 112, the second locking part 1015 first enters the first assembly groove 113 and abuts against it. When the support block 1021 continues to extend forward, under the combined action of the fourth spring 1022 and the locking part body 1013, it deflects downward, ultimately causing the second locking part 1015 to act inside the first assembly groove 113 and further drive the first locking part 1014 to be locked inside the first assembly groove 113, thus realizing the fastening process between the stone hanging body and the system assembly frame. The fastening assembly process under this design improves work efficiency while also greatly improving connection strength and tightness.
