Description

Technical Field

[0001] This utility model belongs to the field of curtain wall building technology, and in particular relates to a frame-type double-layer curtain wall keel spacing adjustment structure. Background Technology

[0002] A framed double-layer curtain wall is an advanced building envelope system consisting of an outer curtain wall and an inner curtain wall, with an air gap between the two layers. The outer curtain wall is commonly made of perforated composite aluminum panels, which can provide sun shading, rain protection, and beautify the building's appearance, and can also reduce external noise interference to a certain extent. The inner curtain wall is mostly made of glass, stone, or aluminum panels, ensuring indoor lighting, spatial transparency, and aesthetics. The air gap between the inner and outer layers acts as a buffer zone, regulating indoor temperature, reducing air conditioning energy consumption, and providing thermal insulation. At the same time, it can also utilize the chimney effect to promote air circulation and improve indoor air quality, combining energy saving and comfort.

[0003] During the installation and maintenance of framed double-layer curtain walls, it is necessary to control the spacing between the keels to ensure structural stability and a smooth appearance. Currently, the framed double-layer curtain walls we construct cannot adjust the spacing between the keels. When the spacing is too small, the keels are easily squeezed and deformed, affecting the overall load-bearing capacity of the curtain wall. When the spacing is too large, uneven gaps will appear, reducing the sealing and insulation effect, and may also cause shaking and abnormal noise under wind pressure, affecting the service life and safety of the curtain wall.

[0020] Figure 1-5This invention illustrates an embodiment of a frame-type double-layer curtain wall keel spacing adjustment structure, comprising a keel 1, with glass curtain walls 2 mounted on both sides of the keel 1 via aluminum alloy hangers. A galvanized steel plate 3 is fixedly connected to the front side of the keel 1, and a frame 4 is provided on the front side of the galvanized steel plate 3. Perforated composite aluminum plates 6 are provided on both the left and right sides of the front side of the frame 4. Connecting hangers 5 are fixedly installed on the front side of the inner cavity of the frame 4, and the two sides of the connecting hangers 5 are fixedly connected to two perforated composite aluminum plates 6. Horizontal connecting plates 7 are fixedly connected to both the left and right sides of the galvanized steel plate 3. The two horizontal connecting plates 7 are located in the inner cavity of the frame 4 and are slidably connected to the frame 4. The inner cavity of the frame 4 is provided with multiple reinforcing L-shaped plates 8. The opposite side of the two horizontal connecting plates 7 is fixedly connected to four reinforcing L-shaped plates 8, and the four reinforcing L-shaped plates located in the middle are fixedly connected to each other. The L-shaped plate 8 is fixedly connected to the galvanized steel plate 3 and the transverse connecting plate 7 by bolts. A movable threaded rod 9 is provided through the central axis of the transverse connecting plate 7. A reinforcing ring 10 is fixedly connected to the rear end of the threaded rod 9. The reinforcing ring 10 is fixedly connected to the frame 4. A threaded ring 11 is threadedly connected to the front side of the surface of the threaded rod 9. A circular washer 12 is fixedly connected to the inner cavity of the front side of the threaded ring 11. The circular washer 12 is fixedly connected to the circular washer 12. A circular ring 13 is provided on the front side of the threaded ring 11. A rotating sleeve 15 is threadedly connected to the front side of the surface of the threaded rod 9. A locking tooth 17 is provided on the rear side of the rotating sleeve 15. The circular ring 13 meshes with the locking tooth 17. Two symmetrical fastening nuts 20 are threadedly connected to the surface of the threaded rod 9. The two fastening nuts 20 are tightly fitted to the transverse connecting plate 7.

[0021] Using the above solution: by rotating the force-applying handle 19, the circular ring 13 and the second retaining tooth 17 are disengaged. Then, the two fastening nuts 20 are rotated, at which point the two fastening nuts 20 are disengaged from the transverse connecting plate 7. Subsequently, the push frame 4 is pushed to adjust the distance on the surface of the galvanized steel plate 3. After the distance is adjusted, the two fastening nuts 20 are tightened to engage the circular ring 13 and the second retaining tooth 17. Finally, the position is tightened by rotating the force-applying handle 19. This achieves the purpose of flexibly adjusting the keel spacing, ensuring spacing accuracy, improving structural stability, and facilitating installation and maintenance.

[0022] refer to Figure 4 A circular recess 16 is tightly fitted to the rear side of the rotating sleeve 15. The circular recess 16 is slidably connected to the threaded rod 9. Multiple protrusions are fixedly connected to the inner wall of the second locking piece 17. The surface of the circular recess 16 is slidably connected to the protrusions on the inner wall of the second locking piece 17.

[0023] The above solution is adopted: through the cooperation of the circular concave block 16 and the inner wall protrusion of the second locking tooth 17, when the second locking tooth 17 drives the protrusion to slide on the surface of the circular concave block 16, the circular concave block 16 plays a limiting role on the protrusion, ensuring that the second locking tooth 17 will not deviate in direction when sliding on the surface of the circular concave block 16, and improving the adaptability of the second locking tooth 17 when meshing with the circular ring 13.

[0024] refer to Figure 3 and Figure 4 A fixed ring 18 is fixedly connected to the surface of the rotating sleeve 15, and multiple force-applying handles 19 are fixedly connected to the surface of the fixed ring 18.

[0025] The above solution is adopted: by using the fixed ring 18 and the force-applying handle 19 together, a stable force-applying fulcrum and force-generating structure are formed when rotating the rotating sleeve 15. First, the fixed ring 18 can limit the axial displacement of the rotating sleeve 15, avoid deviation during rotation, and ensure accurate force application direction. Second, the force-applying handle 19 increases the contact area of ​​the hand, and the rotating sleeve 15 can be easily driven to rotate without the need for additional tools.

[0026] In use, the glass curtain wall 2 is precisely installed on both sides of the keel 1 using aluminum alloy hangers to ensure its flatness and verticality. Then, a galvanized steel plate 3 is fixed to the front of the keel 1, and a perforated composite aluminum plate 6 is fixed to the front of the frame 4 using connecting hangers 5. The transverse connecting plates 7 on both sides of the galvanized steel plate 3 are made to slide against the frame 4. Simultaneously, the galvanized steel plate 3 and the transverse connecting plates 7 are connected by bolts using reinforcing L-shaped plates 8 to improve structural stability. Next, a threaded rod 9 with reinforcing rings 10 is inserted through the transverse connecting plates 7. Threaded rings 11 and circular washers 12 are sequentially installed on the threaded rod 9, and a rotating sleeve 15 with a locking tooth 17 is installed, so that the circular... Ring 13 engages with toothed part 17. Rotating sleeve 15 is connected to force-applying handle 19 via fixed ring 18. Finally, the fastening nut 20 on threaded rod 9 is used to attach to transverse connecting plate 7 to complete pre-fixation. During adjustment, rotating force-applying handle 19 drives rotating sleeve 15, causing toothed part 17 to disengage from circular ring 13. Circular concave block 16 limits toothed part 17 to prevent deviation. Then, loosen fastening nut 20 and push frame 4 to slide along galvanized steel plate 3 to the target spacing. After adjustment, tighten fastening nut 20 and rotate force-applying handle 19 in the opposite direction to re-engage and lock toothed part 17 with circular ring 13, thus achieving adjustment of keel spacing and structural stability.

[0027] In summary, this frame-type double-layer curtain wall keel spacing adjustment structure, by rotating the force-applying handle 19, disengages the circular ring 13 and the second locking tooth 17. Then, by rotating the two fastening nuts 20, the two fastening nuts 20 are disengaged from the horizontal connecting plate 7. Subsequently, the frame 4 is pushed to adjust the distance on the surface of the galvanized steel plate 3. After the distance is adjusted, the two fastening nuts 20 are tightened to engage the circular ring 13 and the second locking tooth 17. Finally, the position is tightened by rotating the force-applying handle 19. This achieves the purpose of flexibly adjusting the keel spacing, ensuring spacing accuracy, improving structural stability, and facilitating installation and maintenance.
