Description

Technical Field

[0001] This invention relates to the field of building construction and installation technology, specifically to a suspended keel frame for building curtain walls and its installation method. Background Technology

[0002] Building curtain walls refer to non-load-bearing exterior wall cladding that is hung up like a curtain, hence the name "curtain wall". They are lightweight wall structures with decorative effects commonly used in modern large and high-rise buildings, and are usually composed of glass panels and a keel frame.

[0003] In existing technologies, when installing a curtain wall, the keel frame needs to be installed on the wall first, and then the glass panels are fixed to the keel frame for support.

[0004] However, during the installation of the curtain wall keel frame, unevenness may occur due to the influence of the flatness of the wall surface. Unevenness of the keel frame directly affects the efficiency of curtain wall installation and the aesthetics after installation. Moreover, uneven installation of the keel frame may also affect subsequent use. To address these issues, we propose a suspended keel frame and installation method for building curtain walls. Summary of the Invention

[0005] The purpose of this invention is to provide a suspended keel frame for building curtain walls and an installation method thereon, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a suspended keel frame for building curtain walls, including a support base, a base provided on the surface of the support base, a support frame provided on the surface of the base, an directional plate provided inside the support frame, a lifting plate provided on the side of the directional plate, a threaded hole provided on the surface of the lifting plate, a lifting screw threaded into the threaded hole, and a third gear sleeved on one end of the lifting screw.

[0007] The frame has a second lifting plate inside, a damping bearing on the end face of the second lifting plate, a limit rod inserted into the damping bearing, a fixed plate on the side of the support frame, a motor inside the fixed plate, a gear sleeved on the drive end of the motor, and a movable plate on the surface of the support frame.

[0009] Preferably, one end of the lifting screw is fitted with a bearing, the lower surface of the bearing is fixedly connected to the surface of the support base, and two sets of lifting screws are provided, which are symmetrically distributed about the side of the directional plate. One set of lifting screws is fitted with a second gear, and the surface of the third gear is fitted with a toothed belt.

[0010] Preferably, the electric motor is powered by an external power supply, a gear sleeved on the transmission end of the electric motor meshes with a second gear for transmission, and the fixing plate is fixedly connected to the side surface of the support frame.

[0011] Preferably, a bracket is disposed on the inner side surface of the orientation plate, a hole is opened at one end of the bracket, a guide rod is disposed in the hole, a mounting frame is disposed at one end of the guide rod, a rotating rod is inserted into the inner side surface of the mounting frame, a pulley is sleeved on the surface of the rotating rod, and the pulley can rotate around the rotating rod.

[0012] Preferably, the bracket is in a "C"-shaped plate-like structure, one end of the bracket is fixedly connected to the inner side surface of the orientation plate, a spring is sleeved on the surface of the guide rod, one end of the spring is fixedly connected to the end surface of the bracket, the other end of the spring is fixedly connected to the side surface of the mounting frame, and the guide rod can slide inside the bracket.

[0013] Preferably, the side surface of the frame body is fixedly connected to the side surface of the support frame, a slide hole is opened in the frame body, the second lifting plate can move up and down in the slide hole, a screw rod is disposed on the side surface of the second lifting plate, a clamping plate is sleeved on the surface of the screw rod, and a positioning nut is screwed on the surface of the screw rod.

[0014] Preferably, the lower surface of the damping bearing is fixedly connected to the end surface of the second lifting plate, the limiting rod is inserted into the inner ring surface of the damping bearing, and the limiting rod has an "L"-shaped rod-like structure.

[0015] A method for installing a suspension keel frame of a building curtain wall, comprising the following steps:

[0016] S1: First, fix the support base on the wall with fixing bolts, insert the keel frame to be fixedly installed into the orientation plate, and make the keel plate butt and fix with another group of keel plates through the supporting and guiding effects of the orientation plate.

[0017] S2: Then after the keel frame is placed in the orientation plate, rotate the limiting rod to fix the keel frame in the orientation plate by using the limiting rod, so as to prevent it from falling out of the orientation plate.

[0018] S3: Finally, when the wall surface is uneven and the levelness of the connection between multiple groups of keel frames cannot be guaranteed, the electric motor can be started, and the lifting screw rod is rotated by the action of the electric motor driving the gear and the second gear, so that the orientation plate can be displaced up and down, thereby adjusting the problem of uneven connection of the keel frames when the wall is uneven.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] This invention proposes a suspended keel frame for building curtain walls and its installation method. In use, the support base is first fixed to the wall using fixing bolts. Then, the keel plates are inserted into the directional plate, which slides along the directional plate to align with the other end of the keel plate. The directional plate is horizontal and parallel to the ground, ensuring alignment when connecting the keel plates to other keel plates. When encountering uneven wall surfaces, the motor is activated, and the engagement of the gear and the second gear rotates the lifting screw, allowing the directional plate to be adjusted vertically within the support frame, ensuring each keel plate is on the same horizontal line. Then, each keel is fixed. After the keel plates are installed, the directional plate is retracted into the support frame, and the fixing bolts are rotated to remove the support base and reposition it for installation of other keel plates. This method is convenient and avoids unevenness in the keel frame caused by wall flatness during installation. Unevenness directly affects the efficiency of curtain wall installation and the aesthetics after installation, and may also affect subsequent use. Attached Figure Description

Furthermore, all embodiments can be used in combination with each other.

[0033] Example 1

[0034] Please see Figures 1 to 7This invention provides a technical solution: a suspended keel frame for a building curtain wall, including a support base 1, a base 2 on the surface of the support base 1, a support frame 3 on the surface of the base 2, a directional plate 4 inside the support frame 3, a lifting plate 5 on the side of the directional plate 4, a threaded hole on the surface of the lifting plate 5, a lifting screw 10 screwed into the threaded hole, a third gear 11 sleeved at one end of the lifting screw 10; a frame 6, a second lifting plate 7 inside the frame 6, a damping bearing 8 on the end face of the second lifting plate 7, a limit rod 9 inserted into the damping bearing 8, a fixing plate 12 on the side of the support frame 3, a motor 13 inside the fixing plate 12, a gear 14 sleeved at the transmission end of the motor 13, and a movable plate 15 on the surface of the support frame 3;

[0035] In use, first, fix the support base 1 to the wall using fixing bolts. Then, insert the keel plate into the guide plate 4. The keel plate slides along the guide plate 4 and aligns with the other end of the keel plate. The guide plate 4 is horizontal and parallel to the ground, which ensures alignment when connecting the keel plate to other keel plates. When encountering uneven wall surfaces, start the motor 13. The motor 13 uses the meshing of gear 14 and second gear 19 to rotate the lifting screw 10. This allows the guide plate 4 to be adjusted up and down within the support frame 3, so that each keel plate is on the same horizontal line. Then, fix each keel. After the keel plate installation is completed, retract the guide plate 4 into the support frame 3. Then, rotate the fixing bolts to remove the support base 1 and change its position for easier installation of other keel plates. The support frame 3 and guide plate 4 are in a cross shape, which facilitates the horizontal and vertical installation of the keel frame.

[0036] Example 2

[0037] Based on Embodiment 1, a movable plate 15 is provided. A lifting hole 16 is provided on the side of the movable plate 15. A scale value 17 is provided on the surface of the movable plate 15. The lifting plate 5 can move up and down within the lifting hole 16. A bearing 18 is sleeved on one end of the lifting screw 10. The lower surface of the bearing 18 is fixedly connected to the surface of the support base 1. Two sets of lifting screws 10 are provided. The two sets of lifting screws 10 are symmetrically distributed about the side of the directional plate 4. A second gear 19 is sleeved on the surface of one set of lifting screws 10, and a toothed belt 20 is sleeved on the surface of the third gear 11. The motor 13 is powered by an external power supply. The gear 14 sleeved on the transmission end of the motor 13 meshes with the second gear 19 for transmission. The fixed plate 12 is fixedly connected to the side of the support frame 3.

[0038] When the uneven wall surface easily causes the keel frame to be uneven after connection and installation, the motor 13 can be started, so that the motor 13 uses the meshing action of the gear 14 and the second gear 19 to make the lifting screw 10 rotate in cooperation with the bearing 18, so that the lifting plate 5 screwed on the lifting screw 10 can be moved up or down, thereby driving the orientation plate 4 to displace within the support frame 3. The third gear 11 cooperating with the toothed belt 20 can make other lifting screws 10 rotate together. The arrangement of the scale value 17 facilitates observation of the displacement distance of the orientation plate 4 to make the displacement more accurate, preventing the problem of inclination at one end of the orientation plate 4. The lifting plate 5 arranged in the lifting hole 16 can prevent the lifting plate 5 from rotating together with the lifting screw 10.

[0039] Embodiment 3

[0040] On the basis of the second embodiment, a bracket 21 is provided. The bracket 21 is of a "C"-shaped plate-like structure, one end of the bracket 21 is fixedly connected to the inner side surface of the orientation plate 4. A spring 26 is sleeved on the surface of the guide rod 22, one end of the spring 26 is fixedly connected to the end surface of the bracket 21, and the other end of the spring 26 is fixedly connected to the side surface of the mounting frame 23. The guide rod 22 can slide inside the bracket 21. The side surface of the frame body 6 is fixedly connected to the side surface of the support frame 3, a slide hole 27 is opened inside the frame body 6, and the second lifting plate 7 can move up and down inside the slide hole 27. A screw 28 is arranged on the side surface of the second lifting plate 7, a clamping plate 30 is sleeved on the surface of the screw 28, and a positioning nut 29 is screwed on the surface of the screw 28. The lower surface of the damping bearing 8 is fixedly connected to the end surface of the second lifting plate 7, the limit rod 9 is inserted into the inner ring surface of the damping bearing 8, and the limit rod 9 is of an "L"-shaped rod-like structure;

[0041] After the keel frame is installed in the orientation plate 4, the limit rod 9 can be rotated, so that the limit rod 9 cooperates with the arrangement of the damping bearing 8 to limit the keel frame in the orientation plate 4. Then the height of the second lifting plate 7 in the frame body 6 is adjusted, and the positioning nut 29 is rotated to cooperate with the clamping plate 30 to fix the second lifting plate 7, so that the limit rod 9 can be used to limit keel frames of different models. The pulley 25 cooperating with the guide rod 22 and the spring 26 can make the pushing of the keel frame in the orientation plate 4 more convenient by means of the arrangement of the pulley 25.

[0042] In actual use, firstly, the support base 1 is fixed to the wall using fixing bolts. Then, the keel plate can be inserted into the guide plate 4. The keel plate slides along the guide plate 4 to align with the other end of the keel plate. The guide plate 4 is horizontal and parallel to the ground, which ensures alignment when the keel plate is connected to other keel plates. When encountering uneven wall surfaces, the motor 13 can be started. The motor 13 uses the meshing of gear 14 and second gear 19 to rotate the lifting screw 10, thus allowing the guide plate 4 to be adjusted up and down within the support frame 3. Each keel plate is on the same horizontal line. Then, each keel is fixed. After the keel plate installation is completed, the directional plate 4 is retracted into the support frame 3. Then, the fixing bolts are turned to remove the support seat 1 and change its position before installing other keel plates. This makes it more convenient. This avoids the problem of uneven keel frames due to the flatness of the wall surface during the installation of the curtain wall keel frame. Uneven keel frames directly affect the efficiency of curtain wall installation and the aesthetics after installation. Moreover, uneven keel frames may also affect subsequent use.

[0043] A method for installing a suspended keel frame for a building curtain wall includes the following steps:

[0044] S1: First, use fixing bolts to fix the support base 1 to the wall. Then, insert the keel frame that needs to be fixed into the directional plate 4. Through the support and guiding effect of the directional plate 4, the keel plate is connected and fixed to another set of keel plates.

[0045] S2: Then, after the keel frame is placed inside the directional plate 4, rotate the limiting rod 9 to fix the keel frame inside the directional plate 4 and prevent it from coming out of the directional plate 4.

[0046] S3: Finally, when the wall surface is uneven and the connection between multiple sets of keel frames cannot be guaranteed to be level, the motor 13 can be started. The motor 13 drives the gear 14 and the second gear 19 to rotate the lifting screw 10. This will cause the directional plate 4 to move up and down, thereby adjusting the problem of uneven connection of the keel frames when the wall is uneven.

[0047] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
