Description

Technical Field

[0001] This invention relates to the field of building curtain walls, and more specifically to a glass curtain wall with a canopy or intermediate layer that can be tilted. Background Technology

[0002] Currently, the cleaning of the exterior curtain wall glass of high-rise buildings is achieved by installing window cleaning machines. These machines are usually installed on the top of the building. When cleaning the windows, the machine arm needs to extend out of the building. However, most existing rooftop glass curtain walls that protrude from the roof cannot be rotated, tilted, or moved. As a result, the window cleaning machines used to clean and maintain the exterior curtain wall can only be installed on an additional steel structure that is higher than the top of the curtain wall. The additional steel structure not only disrupts the original design but may also weaken the overall aesthetic effect of the building's curtain wall to some extent.

[0003] There are also designs for window cleaning machines that can be concealed by rooftop glass curtain walls, without affecting the aesthetics of the building's facade. However, these require custom-made, unconventional window cleaning machines, which have complex structures. Adding a lifting mechanism to the window cleaning machine would result in high purchase costs and subsequent maintenance.

[0004] A small portion of the rooftop glass curtain wall uses a whole movable curtain wall panel to provide a passage for the window cleaning machine to extend out of the building. This avoids affecting the overall aesthetic effect of the building curtain wall and does not require the window cleaning machine to add a complex lifting structure. However, since it needs to move backward and then move horizontally, it is necessary to arrange tracks in both longitudinal and transverse directions. The movement logic is more complex, the reliability requirements of the entire moving system are high, and the structural complexity of the curtain wall panel is increased. Summary of the Invention

[0005] The purpose of this invention is to provide a reversible and tiltable connection system for rooftop glass curtain walls or intermediate layers that protrude from the roof, thereby reducing the situation where, in conventional practices, window cleaning machines for exterior curtain walls can only be installed on additional steel structures that are higher than the top elevation of the curtain wall, which affects the aesthetics of the building facade.

[0006] This invention provides a tiltable glass curtain wall with a crown or intermediate layer. The glass curtain wall includes tiltable unit panels, each with a fixed rotation fulcrum and a movable fulcrum for tilting. The rotation fulcrum is connected to the main structure, and the movable fulcrum is connected to a motorized component. The fixed rotation fulcrum is located below the tiltable unit panel and is rotatably mounted on the main structure. The motorized tilting component includes a slide rail beam along the tilting direction of the tiltable unit panel, with a sliding rod that can slide freely along the length of the slide rail beam. The tiltable unit panel and the sliding rod are connected by a round rod.

[0007] The slide rod is connected to a drive push rod device, which is preferably a hydraulic push rod device, but can also be a helical push rod device. The front part of the telescopic push rod of the hydraulic push rod device is connected to the slide rod, and the hydraulic push rod drives the slide rod and the steel round rod to move.

[0008] One end of the sliding beam is equipped with a track parallel to the curtain wall surface, or the roof or intermediate layer. A hydraulic push rod device is placed on the track and moves along the track. The rear of the hydraulic push rod device is supported on the side of a steel column.

[0009] Limit bolts are installed at both ends of the slide rail beam to prevent the aluminum alloy slide rod from derailing.

[0010] Constraint bolts are installed at both ends of the slide rail beam, with their positions corresponding to the normal working or tilting positions of the tilting unit plate, so as to achieve mechanical fixation of the slide rod position and achieve force balance.

[0011] The problem this invention aims to solve is how to enable window cleaning machines installed on the roof or intermediate levels of a building to extend out of the side curtain wall for normal window cleaning operations. For buildings of average height, window cleaning machines can be installed only on the roof. However, for high-rise or super high-rise buildings, window cleaning machines may be installed on both the roof and intermediate sides. Therefore, the tilting unit panel can be the crown section of the roof. The tilting unit panel and adjacent unit panels form a detachable connection structure. If the tilting unit panel is in the crown section, its three sides form the detachable connection structure. If it is in an intermediate level corresponding to where the window cleaning machine is installed, the four edges of the tilting unit panel and adjacent unit panels form a detachable connection structure. The tilting unit panel and adjacent unit panels can be sealed together with sealing strips, while the unit panel is fixedly supported to the main structure in the normal use position and the tilting position by round rods.

[0012] A preferred embodiment is that the tilting unit panel is installed at the crown of the glass curtain wall, and a window cleaning machine that can extend out of the curtain wall is also installed on the roof. When the tilting unit panel is in the tilted position, the window cleaning arm of the window cleaning machine is higher than the tilting unit panel.

[0013] To utilize the large roof area of ​​the building, the hydraulic push rod equipment is slidably mounted on the I-beam rails via connecting components. The I-beam rails provide vertical support for the tilting unit panels. There are multiple tilting unit panels, and the I-beam rails are parallel to the curtain wall surface, or the rails on the roof or intermediate layer correspond to multiple tilting unit panels.

[0014] A steel column is also installed on the roof, positioned behind the hydraulic push rod device, with the rear end of the push rod of the hydraulic push rod device abutting against the steel column.

[0015] Both fulcrums are connected by lugs and bolts. Lugs are installed at the fulcrums and are bolted to the main structure or moving parts.

[0016] The main structure has a boss at a fixed rotating fulcrum mounting position, and the fixed rotating fulcrum mounting position is located on the side of the boss.

[0017] The upper side of the aluminum alloy slide rail beam is the slide rail section, which is a square cross-section profile with an opening. The lower part of the aluminum alloy slide rod slides in conjunction with the slide rail. The lower half of the aluminum alloy slide rod is a square cross-section profile corresponding to the slide rail section. The upper half of the aluminum alloy slide rod is located outside the slide rail. The upper half of the aluminum alloy slide rod is provided with a round hole for connecting with a steel round rod, so that the slide rod is hinged to the round rod. One end of the aluminum alloy slide rod is provided with a structure for connecting to the front of the hydraulic push rod device.

[0018] The circular hole connecting the upper part of the aluminum alloy slide rod to the steel rod is located at the end of the aluminum alloy slide rod closer to the tilting unit plate, and the structure connecting one end of the aluminum alloy slide rod to the front of the hydraulic push rod device is located at the end of the aluminum alloy slide rod away from the tilting unit plate.

[0019] The aluminum alloy slide rail beam is mounted on two aluminum alloy supports and then on galvanized steel parts via stainless steel bolt assemblies. The galvanized steel parts are then mounted on the main structure via anchor expansion bolts.

[0020] The technical effects of this invention are as follows: The reversible glass curtain wall for the crown or intermediate layer provided by this invention allows the glass curtain wall unit of the crown to have a reversible structure. With the help of motorized components, the unit of the crown can be rotated to a height lower than the window cleaning machine installed on the roof, allowing the conventional window cleaning machine to extend out of the roof to carry out normal window cleaning operations. At the same time, this invention has a simple and effective structure, the components are easy to purchase, process and install, the cost is low, and it is easy to operate. While ensuring the functionality of the curtain wall, it greatly reduces the overall cost of the curtain wall maintenance system.

[0021] Since this invention does not require the use of more hydraulic devices, but only a small hydraulic push rod device is designed, the equipment technology is mature, the cost is low, and the number of devices used is small. The tilting motor device mainly uses aluminum alloy extruded profiles, which has high component fit, high processing accuracy, good corrosion resistance, good economy, and controllable quality. After the unit plate reaches the specified state, it can be mechanically fixed immediately. The operation is simple and clear, easy to inspect, and has a high safety factor.

[0022] By adopting the above solution, the problem of window cleaning machines for exterior curtain walls having to be installed on additional steel structures above the top elevation of the curtain wall, thus affecting the aesthetics of the building facade, can be solved. Furthermore, compared to using customized, unconventional window cleaning machines or entirely mobile solutions, this reduces purchase costs and subsequent high maintenance expenses, significantly lowering the overall cost of the curtain wall maintenance system. Engineering practice has proven that this invention achieves good results. Attached Figure Description

[0025] To make the above-mentioned objectives, features, and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and specific implementation examples.

[0026] like Figure 1 and Figure 2 As shown, the present invention provides a tiltable glass curtain wall with a crown or intermediate layer. The glass curtain wall is provided with a tiltable unit panel 20, which is located in the crown part of the glass curtain wall. The tiltable unit panel 20 has a fixed rotation fulcrum and a movable fulcrum. The rotation fulcrum is connected to the main structure 1, and the movable fulcrum is connected to the motorized component. The rotation fulcrum is connected by ear plate bolts 12, and the movable fulcrum is connected by ear plates 3 and bolts. Ear plates are installed at the fulcrum and are bolted to the main structure 1 or the motorized component.

[0027] A fixed fulcrum is located below the tilting unit plate and is rotatably mounted on the main structure 1. The main structure 1 has a boss 13 at this mounting position, and the fulcrum is mounted on the side of the boss 13. Since the fulcrum needs to provide horizontal force support to the tilting unit plate, this structure provides better support in the force direction. Of course, provided that a corresponding force-bearing structure is set at the top, the fulcrum can also be set at the top of the boss.

[0028] The position of the fulcrum and the shape of the ear plate 3 are determined according to the angle and position of the unit panel to be tilted; the size of each accessory is determined according to the structural stress requirements, so that when the tilting unit panel 20 is tilted into place, its height is lower than the height of the window cleaning arm extended by the window cleaning machine set on the roof.

[0029] The tilting mechanism is constructed by installing an aluminum alloy slide rail beam 8 along the tilting direction of the tilting unit panel of the glass curtain wall. The two ends of the aluminum alloy slide rail beam 8 are connected and fixed to the main structure 1 through adjustable aluminum alloy supports 7. The length of the aluminum alloy slide rail beam 8 is determined according to the tilting angle and position of the unit panel. An aluminum alloy slide rod 4 that can slide freely along the length of the slide rail beam 8 is installed on the aluminum alloy slide rail beam 8. The aluminum alloy slide rod 4 is designed to match the shape of the slide rail beam and is 250mm long.

[0030] M16 limit bolts 6 are installed at both ends of the aluminum alloy slide rail beam 8 to prevent the aluminum alloy slide rod 4 from derailing and to restrain bolts 5. When one end of the slide rod is pressed against the limit bolt 6, it indicates that the tilting unit plate has reached the normal working or tilting position. At this time, the restraint bolt 5 is installed at the other end of the slide rod to achieve mechanical fixation of the slide rod position and achieve force balance.

[0031] The tilting unit panel and the sliding rod are connected by a steel round rod 2 with lugs 3 at both ends bolted together. The lugs 3 can rotate around the bolts. An I-beam rail 9 parallel to the curtain wall surface is set at one end of the aluminum alloy sliding rail beam 8. A small hydraulic push rod device 10 is placed on the I-beam rail 9 and can move along the I-beam rail 9. A steel column 11 is also set on the roof, located behind the hydraulic push rod device 10, with the rear end of the push rod of the hydraulic push rod device 10 abutting against the steel column 11. When the tilting unit panel 20 reaches the designated tilting position, the rear of the hydraulic push rod device 10 is supported by the side of the 160mm x 5mm steel column 11 (see...). Figure 2 The hydraulic push rod device 10 is connected to the slide rod at the front to increase the supporting force. The forward / backward movement of the hydraulic push rod causes the slide rod and the steel round rod 2 to move, thereby realizing the straightening / tilting state of the unit plate. After the specified state is achieved, the constraint bolts 5 are immediately placed to mechanically fix the aluminum alloy slide rod 4 on the aluminum alloy slide rail beam 8. Since the connection point between the tilting unit plate 20, the steel round rod 2, and the aluminum alloy slide rail beam 8 always forms a reliable force triangle, the hydraulic push rod device 10 can move to the next position to work after mechanical fixing.

[0032] like Figure 4 As shown, the aluminum alloy slide rail beam 8 is mounted on two aluminum alloy supports 7 by stainless steel bolt group 16, the aluminum alloy supports 7 are mounted on galvanized steel parts 14 by stainless steel bolt group 15, and the galvanized steel parts 14 are mounted on the main structure 1 by anchor expansion bolts.

[0033] The upper side of the aluminum alloy slide rail beam 8 is the slide rail section, which can be a square cross-section profile with an opening. The lower part of the aluminum alloy slide rod 4 slides in cooperation with the slide rail, corresponding to the square cross-section profile with an opening. The lower half of the aluminum alloy slide rod 4 is a corresponding square cross-section profile. The upper part of the aluminum alloy slide rod 4 is located above the slide rail. The upper part of the aluminum alloy slide rod 4 is provided with a round hole for connecting to the steel round rod 2, and also has a structure for connecting to the front of the hydraulic push rod device 10. The round hole for connecting to the steel round rod 2 is located at the end of the aluminum alloy slide rod 4 near the tilting unit plate, and the structure for connecting to the front of the hydraulic push rod device 10 is located at the end of the aluminum alloy slide rod 4 away from the tilting unit plate. The limiting bolt 6 is installed on the slide rail on the upper side of the aluminum alloy slide rail beam 8. When the unit plate is in the straightening / tilting state, the aluminum alloy slide rod 4 is positioned on the slide rail. The aluminum alloy slide rail beam 8 is provided with a limiting bolt 6 that can lock the aluminum alloy slide rod 4. A constraint bolt 5 is also provided in cooperation with the corresponding limiting bolt 6.

[0034] The hydraulic push rod device 10 is slidably mounted on the I-beam rail 9 via connecting components, and the I-beam rail 9 provides vertical support for it.

[0035] like Figure 3 As shown, the window cleaning machine is installed on the roof. When the tilting unit plate 20 of the roof is in a straight position, the window cleaning arm of the window cleaning machine cannot extend. At this time, the hydraulic push rod device 10 is driven to tilt the tilting unit plate 20. After it is lower than the window cleaning arm, the window cleaning arm can extend to perform normal window cleaning operations.

[0036] When the glass curtain wall is in normal working condition, the tilting unit panel 20 is supported against the main roof structure by the steel round rod 2, aluminum alloy slide rail beam 8, and constraint bolts 5 on it. Its periphery is sealed to the adjacent unit panel by a sealing strip. When window cleaning is to be carried out, the hydraulic push rod device 10 is connected to the aluminum alloy slide rod 4 on the aluminum alloy slide rail beam 8, the constraint bolts 5 are removed, and the hydraulic push rod device 10 is driven to make the tilting unit panel 20 rotate around the pivot point and tilt downward to a suitable height. Then the constraint bolts 5 are installed, and the window cleaning arm of the window cleaning machine can be extended to carry out window cleaning. After window cleaning is completed, the tilting unit panel is reset by the hydraulic push rod device 10 and fixed with constraint bolts.

[0037] This invention has a simple and effective structure, and its components are easy to purchase, process, and install. It is inexpensive and easy to operate, and while ensuring the functionality of the curtain wall, it greatly reduces the overall cost of the curtain wall maintenance system.

[0038] Because this invention only uses a small hydraulic push rod device, the equipment technology is mature, the cost is low, and the number of devices used is small. The tilting motor device mainly uses aluminum alloy extruded profiles, which has high component fit, high processing accuracy, good corrosion resistance, good economy, and controllable quality. The unit plate can be mechanically fixed immediately after reaching the specified state. The operation is simple and clear, easy to inspect, and has a high safety factor.

[0039] By adopting the above solution, the existing technical problem that window cleaning machines for exterior curtain walls can only be installed on additional steel structures above the top elevation of the curtain wall, affecting the aesthetics of the building facade, can be solved. Furthermore, compared to customized, unconventional window cleaning machine solutions and fully mobile solutions, this reduces purchase costs and subsequent high maintenance expenses, significantly lowering the overall cost of the curtain wall maintenance system. Engineering practice has proven that this invention achieves good results.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
