Description

Technical Field

[0001] The invention relates to building curtain wall technology, and in particular to an assembled building curtain wall. Background Art

[0002] In high-rise buildings and large-span buildings, the application of prefabricated curtain walls has shown more significant advantages. As the service life of the building increases, the surface of the curtain wall unit may be affected by the external environment and become aged, deformed or damaged, which requires the curtain wall system to have convenient maintenance and replacement functions. At present, the traditional prefabricated curtain wall system cannot independently disassemble and replace each curtain wall unit, which results in a large amount of manual operation during the maintenance process, and the maintenance is difficult and the maintenance cost is high. Summary of the invention

[0003] The object of the present invention is to provide a prefabricated building curtain wall to solve the above-mentioned deficiencies in the prior art.

[0004] In order to achieve the above object, the present invention provides the following technical solution: an assembled building curtain wall, comprising a curtain wall unit and an assembly part for connecting the curtain wall unit, wherein the assembly part comprises:

[0005] Mounting seat;

[0006] Four connecting seats are arranged in a circular array, and the connecting seats can rotate around a first axis and / or a second axis, wherein the first axis and the second axis are in the same plane and are perpendicular to each other;

[0007] The first rotating shaft and the second rotating shaft are respectively installed at both ends of the connecting seat, and the central axis of the first rotating shaft and the central axis of the second rotating shaft can coincide with the first axis and the second axis respectively;

[0008] Limiting mechanisms are also provided at both ends of the connecting seat, and the limiting mechanisms have a first state and a second state. In the first state, the limitation on the second rotating shaft is released, so that the connecting seat can rotate around the central axis of the first rotating shaft. In the second state, the limitation on the first rotating shaft is released, so that the connecting seat can rotate around the central axis of the second rotating shaft.

[0009] Furthermore, the connecting seat is fan-shaped, and a hemisphere is fixedly mounted on the middle part of one side of the mounting seat close to the connecting seat, and the radius of the hemisphere is smaller than the minimum radius of the connecting seat.

[0010] Furthermore, two ball head rods are fixedly connected to the inner side of the connecting seat, the axis of the two ball head rods are respectively parallel to the first rotating shaft and the second rotating shaft, and the hemisphere is provided with a track groove for the two ball head rods to move.

[0011] Furthermore, two latch pins are arranged on the inner side of the connecting seat, and a plurality of pin holes distributed along the moving track of the latch pins are opened on the hemispherical body.

[0012] Furthermore, the limiting mechanism includes a limiting seat, which is fixedly connected to one side of the mounting seat. The limiting seat is provided with a limiting groove for the first rotating shaft and / or the second rotating shaft to move in or out. A locking member is arranged in the limiting seat, and the locking member can be moved into the limiting groove to limit the movement of the first rotating shaft or the second rotating shaft.

[0013] Furthermore, the locking member includes an L-shaped rod, and a sliding groove is provided in the mounting seat and the limiter for the L-shaped rod to move. When the L-shaped rod moves to a first position at one end of the stroke, one end of the L-shaped rod is located in the limiter groove. When the L-shaped rod moves to a second position at the other end of the stroke, it is located inside the limiter seat and moves out of the range of the limiter groove. The L-shaped rod is connected to a movable member for driving it to move.

[0014] Furthermore, two latch pins are arranged on the inner side of the connecting seat, and a plurality of pin holes distributed along the moving track of the latch pins are opened on the hemispherical body.

[0015] Furthermore, the movable part includes a threaded rod, a first support and a second support are fixedly connected to one side of the mounting seat, the threaded rod is rotatably connected to the first support and the second support, and the inner wall of the L-shaped rod is meshed with the surface of the threaded rod.

[0016] Furthermore, the end of the L-shaped rod located in the limiting groove is inclined, and the L-shaped rod can move to a third position, which is located between the first position and the second position. When it is in the third position, the L-shaped rod is still located in the limiting groove, and the maximum distance of the space formed by the L-shaped rod and the limiting groove is greater than the diameters of the first rotating shaft and the second rotating shaft.

By arranging the first rotating shaft and the second rotating shaft on the connecting seat and the limiting mechanism cooperating therewith, the curtain wall units can be rotated and fixed at the required angle after rotation, so that each curtain wall unit can be operated independently without being interfered by other units, which greatly improves the flexibility and convenience of building installation, maintenance and adjustment.

[0019] 2. The prefabricated building curtain wall is provided with four connecting seats distributed in a circular array, so that the connecting seats can rotate around the first rotating axis or the second rotating axis, and are locked at a suitable position through a limiting mechanism, so that the rotation angle of each curtain wall unit can be precisely controlled, and the operator can adjust the opening position or direction of the curtain wall according to actual environmental changes.

[0033] 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.

[0034] Example:

[0035] See also Figure 1 - Fig.10 , an assembled building curtain wall, comprising a curtain wall unit 1 and an assembly part for connecting the curtain wall unit 1, wherein the assembly part comprises:

[0036] Mounting seat 2;

[0037] Four connecting seats 3 are distributed in a circular array, and the connecting seats 3 can rotate around the first axis and / or the second axis, wherein the first axis and the second axis are in the same plane and are perpendicular to each other. It should be noted that the directions of the first axis and the second axis are optional according to the setting of the angle when the curtain wall is assembled. For example, in this embodiment, the plane where the first axis and the second axis are located is a vertical plane, and the first axis is arranged along the vertical direction, which corresponds to a curtain wall structure assembled along the vertical direction plane, such as Figure 1 In the state shown, the curtain wall unit 1 located at the top rotates around the first axis, and the curtain wall unit 1 located at the bottom rotates around the second axis. Other modes are not described in detail here.

[0038] The first rotating shaft 31 and the second rotating shaft 32 are respectively installed at both ends of the connecting seat 3, and the central axis of the first rotating shaft 31 and the central axis of the second rotating shaft 32 can coincide with the first axis and the second axis respectively;

[0039] Limiting mechanisms 4 are also provided at both ends of the connecting seat 3. The limiting mechanisms 4 have a first state and a second state. In the first state, the restriction on the second rotating shaft 32 is released, so that the connecting seat 3 can rotate around the central axis of the first rotating shaft 31. In the second state, the restriction on the first rotating shaft 31 is released, so that the connecting seat 3 can rotate around the central axis of the second rotating shaft 32.

[0040] In one embodiment of the present invention, the connecting seat 3 is fan-shaped, and a hemispherical body 5 is fixedly mounted on the middle of one side of the mounting seat 2 close to the connecting seat 3, and the radius of the hemispherical body 5 is smaller than the minimum radius of the connecting seat 3;

[0041] The hemisphere 5 is used to separate each connecting seat 3 at the center. There is a certain gap between the surface of the hemisphere 5 and the inner side of the connecting seat 3. When the connecting seat 3 rotates, if the first rotating shaft 31 or the second rotating shaft 32 is slightly deformed after long-term use, the surface of the hemisphere 5 can abut the inner surface of the connecting seat 3 to provide a certain supporting force for the connecting seat 3, thereby increasing its stability during rotation. Taking the first rotating shaft 31 as an example in the vertical direction (the first rotating shaft 31 without other explanations below is taken as an example in the vertical direction), when the connecting seat 3 rotates around the first rotating shaft 31, the second rotating shaft 32 is disengaged, and the connecting seat 3 can abut on the surface of the hemisphere 5 for support under a certain deformation.

[0042] In one embodiment of the present invention, two ball head rods 33 are fixedly connected to the inner side of the connecting seat 3, and the axis of the two ball head rods 33 are parallel to the first rotating shaft 31 and the second rotating shaft 32 respectively. The hemispherical body 5 is provided with a track groove 51 for the two ball head rods 33 to move.

[0043] like Fig. 9 As shown, the cross-sectional shape of the track groove 51 is adapted to the ball head rod 33. In order to avoid large friction resistance during movement, the track groove 51 is slightly larger than the size of the ball head rod 33; the ball head joint of the ball head rod 33 cannot be separated from the track groove 51 when moving. It should be noted that the track groove 51 includes a first groove 52 and a second groove 53. For the same connecting seat 3, they are respectively different movement trajectories corresponding to the movement of the two ball head rods 33 when the first rotating shaft 31 and the second rotating shaft 32 rotate, as shown in FIG. Figure 2 and Figure 3 As shown;

[0044] It should be understood that since four connecting seats 3 are provided, when they rotate around the first rotating shaft 31 and the second rotating shaft 32, the corresponding track grooves 51 are at the same position, so the track grooves 51 are connected, such as Figure 2 shown.

[0045] By providing the ball head rod 33 and the track groove 51 , when the connecting seat 3 rotates, it can move under the constraint of the track groove 51 , thereby improving its stability during movement.

[0046] In one embodiment of the present invention, two latches 34 are further provided on the inner side of the connection seat 3, and a plurality of pin holes 54 are provided on the hemispherical body 5 along the moving track of the latches 34. By moving the latches 34 into the pin holes 54, the connection seat 3 can stop at the position where the pin holes 54 are set when rotating;

[0047] Specifically, a movable cavity 35 for the bolt 34 to move is provided in the connection seat 3, and one end of the bolt 34 away from the hemispherical body 5 is fixedly connected to a lever 36, one end of the lever 36 is located outside the connection seat 3, and a slot for the lever 36 to move is provided on the connection seat 3. During the rotation of the connection seat 3, the bolt 34 is driven to move by moving the lever 36 and locked with one of the pin holes 54, so that the connection seat 3 is fixed at the current rotation position. It should be noted that the setting position of the pin hole 54 determines the rotation angle of the connection seat 3. In actual use, the staff can freely select the pin hole 54 at a suitable position according to the required rotation angle.

[0048] It is worth mentioning that the latch 34 can also be installed at the ball head rod 33. Specifically, the movable cavity 35 is also located inside the ball head rod 33, that is, the movable cavity 35 is opened at the connecting seat 3 and the ball head rod 33. When the latch 34 moves, it extends or retracts from the end of the ball head rod 33, and the pin hole 54 is opened inside the corresponding track groove 51. Fig.10 shown.

[0049] In one embodiment of the present invention, the limiting mechanism 4 includes a limiting seat 41, the limiting seat 41 is fixedly connected to one side of the mounting seat 2, and a limiting groove 42 is provided on the limiting seat 41 for the first rotating shaft 31 and / or the second rotating shaft 32 to move in or out, and a locking member is provided in the limiting seat 41, and the locking member can be moved into the limiting groove 42 to limit the first rotating shaft 31 or the second rotating shaft 32 from moving out;

[0050] Specifically, the locking member includes an L-shaped rod 43, and a sliding groove is provided in the mounting seat 2 and the limiter for the L-shaped rod 43 to move. When the L-shaped rod 43 moves to the first position at one end of the stroke, one end of the L-shaped rod 43 is located in the limit groove 42. When the L-shaped rod 43 moves to the second position at the other end of the stroke, it is located inside the limit seat 41 and moves out of the range of the limit groove 42. The L-shaped rod 43 is connected to a moving member 44 for driving it to move.

[0051] In one embodiment of the present invention, at least two first rotating shafts 31 and second rotating shafts 32 are provided on the same connecting seat 3, and the first rotating shafts 31 located at the same position and installed on different connecting seats 3 are alternately distributed, such as Figure 5 As shown, the first rotating shaft 31 and the second rotating shaft 32 are both fixedly connected to the corresponding connecting seat 3 through the bracket 37. It should be noted that the limiting seat 41 is also provided with a groove for the bracket 37 to move in and out;

[0052] It should be understood that since the trajectories of the first rotating shaft 31, the second rotating shaft 32 and the corresponding brackets 37 when moving are circular trajectories, the corresponding parts of the limit seat 41 require a certain inclination angle. During actual processing, a certain inclination angle can be polished so that it will not hinder the movement of the first rotating shaft 31, the second rotating shaft 32 and the corresponding brackets 37.

[0053] In one embodiment of the present invention, the moving member 44 includes a threaded rod 441, a first support 442 and a second support 443 are fixedly connected to one side of the mounting seat 2, the threaded rod 441 is rotatably connected to the first support 442 and the second support 443, the inner wall of the L-shaped rod 43 is meshedly connected to the surface of the threaded rod 441, and the L-shaped rod 43 is moved by rotating the threaded rod 441, and a nut for screwing can be installed at one end of the threaded rod 441;

[0054] For the method of setting a plurality of first rotating shafts 31 and second rotating shafts 32, the L-shaped rods 43 are fixedly connected by connecting plates 444, such as Figure 8 As shown, the inner wall of the connecting plate 444 is meshed with the surface of the threaded rod 441. In order to ensure the movement of the L-shaped rod 43 required for the synchronous driving of the connecting plate 444, the connecting rod and the first support 442 and the second support 443 are slidably matched through the guide rod 445. The principle is common knowledge in the prior art and will not be elaborated here.

[0055] In one embodiment of the present invention, it is difficult to keep the corresponding first rotating shaft 31 or second rotating shaft 32 in the connecting seats 3 on two adjacent mounting seats 2 aligned with each other during the actual assembly process. Therefore, when the curtain wall unit 1 rotates, it often encounters a certain resistance. Specifically, this is because when the curtain wall unit 1 rotates, one side of it needs to be connected to two connecting seats 3 on different mounting seats 2 at the same time. Figure 1 As shown, if the rotation center axes corresponding to the first rotating shafts 31 of the two connecting seats 3 on different mounting seats 2 have poor coincidence, it will cause a certain extrusion pressure to appear at the installation position of the curtain wall unit 1 and the connecting seat 3. In the prior art, the curtain wall unit 1 and the connecting seat 3 can be partially disconnected (maintaining the connection state, but the connection part has a certain movable space, which is the function of the connecting piece connected to the curtain wall unit 1) to avoid the above problem. However, in this case, the connection stability between the curtain wall unit 1 and the connecting seat 3 will be reduced, and there will be certain safety hazards. Therefore, a method for solving the above problem is proposed. Specifically, the end of the L-shaped rod 43 located in the limiting groove 42 is inclined, and the L-shaped rod 43 can be moved to a third position, which is between the first position and the second position. When it is in the third position, the L-shaped rod 43 is still located in the limiting groove 42, and the maximum distance of the space formed by the L-shaped rod 43 and the limiting groove 42 is greater than the diameter of the first rotating shaft 31 and the second rotating shaft 32.

[0056] like Figure 6 and Figure 8As shown, when the L-shaped rod 43 moves to the third position, the first rotating shaft 31 or the second rotating shaft 32 can move within a certain range under the condition of being limited, so that when the central axis overlap of the first rotating shaft 31 or the second rotating shaft 32 corresponding to the connecting seat 3 on two adjacent mounting seats 2 is low, the extrusion pressure occurring at the mounting position of the curtain wall unit 1 and the connecting seat 3 is reduced, and the curtain wall unit 1 can rotate stably while ensuring the connection stability between the curtain wall unit 1 and the connecting seat 3.

[0057] In one embodiment of the present invention, when a curtain wall unit 1 needs to be opened, Figure 1 Taking the rotation direction of the curtain wall unit 1 located at the top as an example (rotating around the first rotation axis 31), the side that needs to move freely needs to be separated from the connecting seat 3 of the two mounting seats 2. The staff can directly remove the locking bolt on the connecting seat 3 connected thereto, and then switch the upper limit mechanism 4 of the two connecting seats 3 still connected thereto to the first state. At this time, the curtain wall unit 1 can rotate around the first rotation axis 31. It should be noted that for the disassembly method, the upper limit mechanism 4 of the two connecting seats 3 still connected thereto can also be switched to the first state first, and then the connection between the other end and the connecting seat 3 can be disassembled;

[0058] Then the staff can directly rotate the curtain wall unit 1 to rotate it around the first rotation axis 31. In actual use, auxiliary parts can be used to improve safety. For example, for a glass curtain wall, it can be fixed by auxiliary parts such as suction cups to prevent the curtain wall unit 1 from falling off due to aging of the mounting base 2.

[0059] After the curtain wall unit 1 is rotated to a suitable position, the staff can move the lever 36 to lock the latch 34 with the pin hole 54, thereby rotating the curtain wall unit 1 to a desired angle and fixing it at the position, and then proceed with normal operations.

[0060] When the curtain wall unit 1 needs to be rotated to Figure 2 When the curtain wall unit 1 is in the position shown in the figure, it needs to rotate around the second rotating shaft 32. The staff can directly remove the locking bolt on the connecting seat 3 connected thereto, and then switch the upper limit mechanism 4 of the two connecting seats 3 still connected thereto to the second state. At this time, the curtain wall unit 1 can rotate around the second rotating shaft 32. After the staff rotates the curtain wall unit 1 to the appropriate position, the staff locks the latch 34 with the pin hole 54 by moving the lever 36, so that the curtain wall unit 1 is rotated to the required position for normal operation.

[0061] Through the above-mentioned method, the prefabricated building curtain wall is very convenient before and after installation and in subsequent repair and maintenance. During installation, since each curtain wall unit 1 can be opened and closed separately, it can be operated at any height when installed on the building structure. When performing maintenance, repair or adjustment during the installation process, the staff can open the curtain wall unit 1 at the corresponding position or adjacent position, so that the staff can directly operate at the current curtain wall unit 1 position without hanging from the high altitude outside. The parts used for maintenance can also be transported from the opening formed by the rotation of the curtain wall unit 1, which improves the convenience of operation for the staff and avoids the need for the staff to hang from the top of the building to work during maintenance.

[0062] In addition, since each curtain wall unit 1 can be rotated independently and the rotation direction is controllable, the movement of the curtain wall unit 1 can be assisted by auxiliary parts (such as glass curtain walls, which can be assisted by suction cups), so that the rotation direction of the curtain wall unit 1 can be diversified to adapt to different environmental requirements. For example, in rainy and snowy weather, the curtain wall unit 1 can be rotated to the top of the opening. In windy weather, the curtain wall unit 1 can be rotated to the side that blocks the wind. If the opening needs to be large enough, several adjacent curtain wall units 1 can be rotated away from each other to make the opening large enough. Figure 1 In the installation state shown, theoretically, at least four openings covered by adjacent curtain wall units 1 can be opened. Of course, it is not appropriate for all the connecting seats 3 on the same mounting seat 2 to be in a rotating state. When the curtain wall unit 1 rotates, the other side is in a free moving state, the center of gravity will also change, and the load on the mounting seat 2 will also increase. Therefore, for the same mounting seat 2, the best state is that only one curtain wall unit 1 connected thereto rotates.

[0063] By enabling the curtain wall unit 1 to rotate independently, and the direction of rotation can be selected according to actual needs, by arranging the first rotating shaft 31 and the second rotating shaft 32 on the connecting seat 3, and the limiting mechanism 4 cooperating therewith, the curtain wall unit 1 can be rotated and can be fixed at a desired angle after rotation, so that each curtain wall unit 1 can be operated independently without being interfered by other units, which greatly improves the flexibility and convenience of building installation, maintenance and adjustment.

[0064] 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.
