[0002] Curtain wall is the outer wall of the building, which is non-load-bearing and is hung like a curtain, so it is also called "curtain wall". It is a lightweight wall with decorative effect commonly used in modern large and high-rise buildings. Curtain wall is mainly composed of panels and supporting structure system. It can have a certain displacement ability relative to the main structure or a certain deformation ability itself, and is a building external protective structure or decorative structure that does not bear the effect of the main structure.

[0003] A suspended curtain wall is a curtain wall that is installed by hanging. An existing method of installing a suspended curtain wall is to first install a keel structure (i.e., a supporting structure system) on the outside of the building wall, and then hang the curtain wall (i.e., the panel) on the keel structure.

[0004] However, a large number of bolts are required in the process of installing the keel structure on the outside of the building wall and in the process of hanging and fixing the curtain wall on the keel structure, that is, the structural strength of the suspended curtain wall after installation is positively correlated with the tightening degree of the bolts. In the installation process of the suspended curtain wall, the large number of bolts to be tightened also means that the operation requirements for the construction workers are higher; and because the number of bolts to be tightened is large, it takes a long time to tighten the bolts during the installation process, resulting in a long construction period and low efficiency. Summary of the invention

[0005] The present application provides a hanging curtain wall connection and fixing device, which makes the installation process of the hanging curtain wall more convenient and quick, simplifies the operation and improves the efficiency.

[0006] The present application provides a hanging curtain wall connection and fixing device, which adopts the following technical solution:

[0007] A hanging curtain wall connection and fixing device comprises a keel structure for hanging and installing a plurality of curtain walls, and also comprises a plurality of preset structures, wherein the keel structure comprises a plurality of vertical keels and a plurality of horizontal keels, wherein the preset structures are fixedly arranged on the outside of the wall, and the plurality of vertical keels correspond to the plurality of preset structures one by one, and the vertical keels are connected to the preset structures; the plurality of vertical keels are arranged vertically and parallel to each other, and the two ends of the vertical keels are respectively connected to the other vertical keels; the plurality of horizontal keels are arranged horizontally and parallel to each other, and the two ends of the horizontal keel are respectively connected to the two vertical keels;

[0008] It also includes a plurality of suspension structures, which are arranged on the transverse keel, and the plurality of suspension structures correspond to the plurality of transverse keels one by one; the suspension structure includes a hook member, a pressing member and a first linkage assembly, the hook member is located below the pressing member, the hook member is slidably connected to the transverse keel in a vertical direction, the pressing member is rotatably connected to the transverse keel, the first linkage assembly is arranged on the transverse keel, and the hook member slides through the first linkage assembly to drive the pressing member to rotate;

[0009] One side of the curtain wall is provided with a plurality of hanging parts, and the hanging parts are provided with hanging grooves adapted to the hook members; after the hook members enter the hanging grooves, the gravity of the curtain wall drives the hook members to slide downward, and the downward sliding of the hook members drives the pressing members to rotate in the direction close to the hanging parts, and when the hook members slide to the extreme position, the pressing members press against the hanging parts.

[0010] By adopting the above technical scheme, during the installation of the suspended curtain wall, the preset structure is first fixedly installed on the outer side of the wall, and then the keel structure is installed, and finally the curtain wall is suspended and fixed on the transverse keel; when the curtain wall is suspended and fixed on the transverse keel, the movement of the curtain wall is controlled so that the hook member is plugged into and matched with the hanging groove on the hanging part, and at this time, the control of the curtain wall is slowly released, and the curtain wall will move downward under the action of its own gravity, while driving the hook member to slide downward, and the downward sliding of the hook member drives the pressing member to rotate through the first linkage assembly, and finally when the hook member slides downward to the extreme position, the pressing member rotates to press against the top of the hanging part, thereby fixing the position of the curtain wall on the transverse keel; it can make the hanging, installation and fixing process of the curtain wall on the transverse keel more convenient and quick, simplify the operation process, and improve the construction efficiency, so that the installation process of the suspended curtain wall is more convenient and quick.

[0011] Optionally, the suspension structure further includes a plurality of first elastic members, wherein the first elastic members are disposed on the transverse keel, and the first elastic members drive the hook member to slide upward to an extreme position and maintain the position.

[0012] By adopting the above technical solution, before the curtain wall is suspended and fixed on the transverse keel, a plurality of first elastic members drive the hook member to slide upward to the extreme position and maintain it, which can reduce the probability of position interference caused by the clamping member in the process of controlling the movement of the curtain wall to make the hook member plug and match with the hanging groove on the hanging part, thereby making the process of plugging and matching the hook member with the hanging groove on the hanging part more convenient.

[0013] Optionally, when the hook member slides upward to the extreme position, the abutting member is in a vertical state, and after the curtain wall keeps the hanging portion against the abutting member and moves downward, the hook member is inserted into the hanging groove.

[0014] By adopting the above technical solution, during the process of hanging, installing and fixing the curtain wall on the horizontal keel, the curtain wall is first controlled to move in a vertical state so that the hanging part and the fastening member are abutted against each other, and then the hanging part and the fastening member are kept abutting against each other, and then the curtain wall is controlled to move downward so that the hook member and the hanging groove on the hanging part can be plugged and matched. The fastening member can play a guiding role in the process of plugging and matching the hook member and the hanging groove on the hanging part, thereby facilitating the operation of construction personnel.

[0015] Optionally, both sides of the abutting member have positioning portions, and the distance between the two positioning portions is the same as the length of the hanging portion.

[0016] By adopting the above technical solution, during the process of hanging and fixing the curtain wall on the horizontal keel, the curtain wall is controlled to move in a vertical state so that the hanging part abuts against the fastening part, and then the hanging part enters the space between the two positioning parts and then the curtain wall is controlled to move downward. The two positioning parts can further play a guiding role in the process of plugging and matching between the hook part and the hanging groove on the hanging part, so that after the curtain wall moves downward, the hook part can be aligned with the hanging groove on the hanging part and plug-fit, thereby further facilitating the operation of construction personnel.

[0017] Optionally, the preset structure includes a carrier, a second linkage component, a sliding member and two fasteners, the carrier is fixedly connected to the wall, the two fasteners are respectively located at two ends of the carrier in the vertical direction, and the fasteners are slidably connected to the carrier in a direction perpendicular to the plane where the carrier is located; the sliding member is slidably connected to the carrier in the vertical direction, and the sliding member is located between the two fasteners; the second linkage component is arranged on the carrier, and the sliding member slides through the second linkage component to drive the two fasteners to slide synchronously in the same direction;

[0018] The vertical keel is provided with a slot for the sliding member to be inserted into and two slots for the fastener to be inserted into, and the slot is adapted to the sliding member; when the sliding member is plugged into the slot, the gravity of the vertical keel drives the sliding member to slide downward, and the fastener inserted into the slot slides toward the direction close to the carrier; when the sliding member slides downward to the extreme position, the fastener abuts against the slot wall of the slot, and the fastener slides to tightly fix the vertical keel on the carrier.

[0019] By adopting the above technical scheme, after the carrier is connected to the wall, the preset structure is installed on the wall, and then the vertical keel is installed and fixed with the help of the preset structure; first, the vertical keel is controlled to move so that the sliding member is inserted into the slot, and at the same time, the two fasteners will be stuck in the corresponding slots, and then the control of the vertical keel is slowly released, and the vertical keel will move downward under the action of its own gravity. The downward movement of the vertical keel will drive the sliding member to slide downward and the two fasteners will slide relative to the vertical keel in a state of engagement with the slots, and at the same time, the downward movement of the sliding member will drive the two fasteners to slide synchronously and in the same direction toward the carrier through the second linkage component. When the sliding member slides downward to the extreme position, the two fasteners both abut against the groove wall of the corresponding slot and jointly fix the vertical keel on the carrier; the process of installing and fixing the horizontal keel on the outside of the wall with the help of the preset structure can be made more convenient and quick, the operation process can be simplified, and the construction efficiency can be improved, thereby making the installation process of the suspended curtain wall more convenient and quick.

[0020] Optionally, the preset structure further includes a plurality of second elastic members, wherein the second elastic members are disposed on the carrier, and the second elastic members drive the sliding member to slide upward to an extreme position.

[0021] By adopting the above technical solution, before the vertical keel is installed and fixed on the outside of the wall with the help of the preset structure, a number of second elastic members drive the sliding member to slide upward to the extreme position and maintain it, so that the vertical keel drives the sliding member to slide the same distance during the installation process, thereby effectively ensuring that the sliding member slides through the second linkage component to drive the two fasteners to rotate and screw in to the same degree and just fix the vertical keel on the carrier, thereby making the operation process of installing and fixing the vertical keel on the outside of the wall with the help of the preset structure more convenient.

[0022] Optionally, one end of the vertical keel in the length direction has a plug-in portion, and the other end of the vertical keel in the length direction is provided with a matching groove adapted to the plug-in portion; after the vertical keel is connected to the preset structure, the plug-in portion of the vertical keel is plugged and matched with the matching groove of another vertical keel.

[0023] By adopting the above technical solution, after several vertical purlins are installed and fixed on the outside of the wall with the help of the preset structure, the plug-in part of the vertical purlin will be plugged into and matched with the matching groove of another vertical purlin to form a connection, thereby improving the connection strength between adjacent vertical purlins, and then improving the overall structural strength of the purlin structure; at the same time, during the plug-in and matching process between the plug-in part and the matching groove, it can also guide the installation of the vertical purlin, thereby further facilitating the installation and fixation of the vertical purlin on the outside of the wall with the help of the preset structure.

[0024] Optionally, both ends of the vertical keels in the length direction are provided with positioning pieces extending toward both sides, and after the two vertical keels are plugged in and matched, a positioning space matching the end of the horizontal keel is formed between adjacent positioning pieces on different vertical keels.

[0025] By adopting the above technical solution, after several vertical purlins are installed and fixed on the outside of the wall with the help of a preset structure, the positioning space formed between adjacent positioning parts on different vertical purlins can facilitate construction workers to determine the installation position of the horizontal purlin, thereby making the installation and fixing process of the horizontal purlin more convenient and quick, simplifying construction operations and improving efficiency.

[0026] Optionally, the keel structure further includes a locking assembly, which is arranged on the transverse keel, and the locking assembly is arranged at both ends of the length direction of each transverse keel;

[0027] The locking assembly includes a locking piece and a control piece. The locking piece is threadedly engaged with the transverse keel and can enter and exit the transverse keel. A through hole is provided on the vertical keel for the locking piece to pass through. The outward end of the locking piece has a spiral locking portion. When two adjacent locking pieces pass through the same vertical keel and the locking piece is located at the extreme position farthest from the transverse keel, the two locking portions cooperate with each other to interlock and fix the two locking pieces. The control piece is rotationally connected to the transverse keel, and the rotation of the control piece drives the locking piece to rotate.

[0028] By adopting the above technical solution, after the transverse keel is fixedly installed between two vertical keels that are parallel to each other and have been installed and fixed, the rotating control member drives the locking member to rotate and screw out outward, and the screwed out locking member will penetrate into the through hole, so that a connection is formed between the transverse keel and the two adjacent vertical keels, thereby improving the connection strength between the transverse keel and the vertical keels, and further improving the structural strength of the keel structure as a whole; in addition, when the locking members on the two adjacent transverse keels penetrate into the interior of the same vertical keel, the two spiral locking parts will cooperate with each other, so that the two locking members are interlocked, thereby fixing the relative positions of the two adjacent transverse keels, and further improving the structural strength of the keel structure.

[0029] In summary, the present application includes at least one of the following beneficial effects:

[0030] 1. It can greatly reduce the use of bolts in the installation process of suspended curtain walls. In the process of installing the keel structure on the outside of the wall and hanging the curtain wall on the keel structure, the keel structure can be fixed to the wall and the curtain wall can be fixed to the keel structure at the same time, thereby simplifying the operation process, reducing the time required for the installation of suspended curtain walls, and improving efficiency;

[0031] 2. When installing and fixing the keel structure, the connection strength between the vertical keels, the connection strength between the horizontal keels, and the connection strength between the vertical keels and the horizontal keels can be improved, thereby improving the overall structural strength of the keel structure, so that the suspended curtain wall can still have a high position stability after being installed and fixed on the outside of the wall while reducing the number of bolts used.

The slot 111, the clamping slot 112 and the clearance slot 113 all penetrate the vertical keel 11. The slot 111 is matched with the portion of the sliding member 22 located outside the carrier 21, the clearance slot 113 is matched with the abutment portion 243, and the clamping slot 112 is matched with the guide portion 242. The clamping slot 112 corresponds to the clearance slot 113 one by one, the clamping slot 112 is located above the corresponding clearance slot 113, and the clamping slot 112 and the clearance slot 113 are communicated.

[0065] When the sliding member 22 is kept at the extreme position under the action of the second elastic members 25, in the process of controlling the vertical keel 11 to move so that the part of the sliding member 22 outside the carrier 21 is inserted into the slot 111, the abutting portions 243 of the two fasteners 24 will also pass through the clearance groove 113 and enter the interior of the vertical keel 11, and at this time, there is a gap between the abutting portions 243 of the fasteners 24 and the cavity wall of the vertical keel 11 close to the carrier 21; the vertical keel 11 and the carrier 21 end surfaces are in contact with each other and move downward at the same time, and the vertical keel 11 will drive the sliding member 22 to slide downward, and the sliding member 22 will slide downward through the second elastic members 25. The linkage assembly 23 drives the two fasteners 24 to slide synchronously in the direction close to the carrier 21, and the guide parts 242 of the two fasteners 24 will be inserted into the corresponding slots 112; when the vertical keel 11 drives the sliding member 22 to slide downward to the limit position, the sliding member 22 supports the vertical keel 11 vertically upward, and the guide parts 242 of the two fasteners 24 abut against the groove wall of the slot 112, and the fastener 24 slides in the direction close to the carrier 21 until the abutment part 243 abuts against the cavity wall of the vertical keel 11 close to the carrier 21, and the abutment part 243 presses the vertical keel 11 on the carrier 21 to fix the position. In this embodiment, it is preferred that one end of the abutment part 243 close to the carrier 21 is also fixedly installed with an elastic pad for contacting and abutting against the cavity wall of the vertical keel 11 close to the carrier 21. Since this is a common prior art, it will not be described here.

[0066] The two ends of the vertical purlin 11 in the length direction respectively have an inserting portion 114 and a matching groove 115, and the matching groove 115 is adapted to the inserting portion 114. After the installation of several vertical purlins 11 in the same vertical direction is completed, the inserting portion 114 on the vertical purlin 11 will be inserted and matched with the matching groove 115 on an adjacent vertical purlin 11. In this embodiment, after the vertical purlin 11 is installed, the inserting portion 114 is preferably located at the bottom of the vertical purlin 11, and the matching groove 115 is located at the top of the vertical purlin 11.

[0067] Reference Figure 6 and Figure 7 , both ends of the vertical keel 11 in the length direction have positioning pieces 116 extending outwards in both sides, the cross section of the positioning piece 116 is L-shaped, and the positioning piece 116 extends outwards in a direction perpendicular to the length direction of the vertical keel 11 and parallel to the outer side surface of the wall 4. After the installation of several vertical keels 11 is completed, a positioning space 117 for the end of the horizontal keel 12 to be inserted is formed between the adjacent positioning pieces 116 on the same side of two adjacent vertical keels 11 in the same vertical direction, and the positioning space 117 is adapted to the end of the horizontal keel 12; after the end of the horizontal keel 12 is inserted into the positioning space 117, the horizontal keel 12 is fixed relative to the vertical keel 11.

[0068] Reference Figure 6 and Figure 8The keel structure 1 also includes a plurality of locking components 13 , which are mounted on the transverse keels 12 . Two locking components 13 are mounted on each transverse keel 12 , and the two locking components 13 are respectively located at both ends of the transverse keel 12 in the length direction.

[0069] The locking assembly 13 includes a control member 131 and a locking member 132. The control member 131 is installed at the bottom of the transverse keel 12. The control member 131 is rotatably connected to the transverse keel 12, and the rotation axis of the control member 131 is parallel to the length direction of the transverse keel 12; the locking member 132 is threadedly matched with the transverse keel 12, and the locking member 132 can enter and exit the interior of the vertical keel 11 along the length direction of the transverse keel 12. The vertical keel 11 is provided with a through hole 118 for the locking member 132 to pass through at the plug-in portion 114 and the plug-in slot. After both ends of the transverse keel 12 are positioned in the positioning space 117, the locking member 132 and the through hole 118 are engaged along the length direction of the transverse keel 12. The length direction of the keel 12 is aligned; the end of the locking member 132 away from the vertical keel 11 has a gear structure, and the control member 131 itself also has a gear structure. The gear structure of the control member 131 meshes with the gear structure of the locking member 132. The rotation of the control member 131 can drive the locking member 132 to rotate out in the direction close to the vertical keel 11 or rotate in in the direction away from the vertical keel 11; the end of the locking member 132 close to the vertical keel 11 has a locking portion 1321, and the locking portion 1321 is a spiral structure, and the locking portions 1321 of the two adjacent locking members 132 inserted into the same vertical keel 11 cooperate with each other, and can form a cylindrical structure together after cooperation. In this embodiment, the locking portion 1321 is preferably a double helical structure, and a single helical structure can also be used in other embodiments.

[0070] The process of screwing the locking piece 132 out or in relative to the transverse keel 12 is limited. When the locking piece 132 is screwed out to the extreme position in the direction close to the vertical keel 11, the locking parts 1321 of the two adjacent locking pieces 132 inserted into the same vertical keel 11 can just cooperate to form a cylindrical structure, so that the relative positions of the two locking pieces 132 are fixed, thereby fixing the relative positions between the two transverse keels 12; when the locking piece 132 is screwed in to the extreme position in the direction away from the vertical keel 11, the locking piece 132 is located as a whole inside the transverse keel 12.

[0071] The implementation principle of a hanging curtain wall connection and fixing device in the embodiment of the present application is:

[0072] In the process of installing and fixing the keel structure 1 with the help of the preset structure 2, the vertical keel 11 is first controlled to move so that the sliding member 22 is inserted into the slot 111 and the two fasteners 24 are inserted into the corresponding clearance slots 113. Then, the control of the vertical keel 11 is slowly released, and the vertical keel 11 will move downward along the carrier 21 to drive the sliding member 22 to slide downward, and the two fasteners 24 are both inserted into the slots 112. The sliding member 22 will slide downward to drive the two fasteners 24 to slide synchronously in the direction close to the carrier 21 through the second linkage assembly 23. Finally, when the vertical keel 11 drives the sliding member 22 to slide downward to the extreme position, the two fasteners 24 can press the vertical keel 11 against the carrier 21 and fix it.

[0073] After the installation of several vertical keels 11 is completed, several positioning members 116 form several positioning spaces 117, and then the movement of the transverse keel 12 is controlled so that the two ends of the transverse keel 12 are respectively stuck in the positioning spaces 117 and fixed in position, and then the rotating control member 131 drives the locking member 132 to rotate out in the direction close to the adjacent vertical keel 11, and the locking member 132 is rotated out in the direction close to the adjacent vertical keel 11 until the locking parts 1321 of the two adjacent locking members 132 that penetrate into the same vertical keel 11 cooperate with each other, and then the position of the transverse keel 12 relative to the vertical keel 11 is fixed, and the relative positions of the two adjacent transverse keels 12 are fixed.

[0074] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
