The device comprises a base fixed to a building curtain wall bracket and a detachable decorative strip connected to the base by screws. During maintenance, only the detachable decorative strip needs to be removed without removing the entire exposed frame decorative strip. The above device can solve the problems of complicated operation and material waste caused by maintenance, replacement and modification of the exposed frame decorative strip after installation.

[0003] However, the above-mentioned installation structure of the exposed frame decorative strips of the building curtain wall still has obvious defects during use: 1. The curtain wall decorative strips of the above-mentioned device can only decoratively cover the opening of the base, and cannot seal the inside of the base from the outside. When water enters the inside of the base, the bolts may rust and loosen, which may cause the glass curtain wall clamp to loosen, and then there is a risk of the glass curtain wall falling and injuring people and vehicles on the ground; 2. The above-mentioned device and most of the curtain wall decorative strips on the market are only fixed to the base by bolts, and holes need to be opened on the base, which makes installation difficult; 3. The vast majority of curtain walls currently disclosed only form a sealing mechanism through sealing strips, and this sealing method is affected by the quality of the sealing strips. With the passage of time, the sealing colloid will age and affect its sealing performance, and it is difficult to effectively block gaseous water such as water vapor. Therefore, there is still a risk of water vapor entering and causing corrosion of the steel structure. Summary of the invention

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] See also Figure 1-6 , the present invention provides a technical solution:

[0024] A curtain wall decorative strip connection structure includes a curtain wall bracket 1, a base 2 and a curtain wall decorative strip 3. The curtain wall bracket 1 and the base 2 clamp and fix a glass curtain wall 5 through bolts 4. The curtain wall decorative strip 3 is clamped on the outside of the base 2. The outer periphery of the base 2 is wrapped by the curtain wall decorative strip 3. A desiccant circulation gap 25 between the base 2 and the curtain wall decorative strip 3 is filled with desiccant, thereby preventing water vapor from entering the base 2, thereby causing rust of the bolts and steel structure, ensuring the stability of the curtain wall structure, and extending the service life;

[0025] The curtain wall decorative strip 3 is provided with a recess 6, and pulling blocks 7 are movably provided at the upper and lower ends of the inner side of the recess 6. The pulling blocks 7 are fixedly connected to the threaded rod 8, and the threaded rod 8 extends into the mechanism cabin 9 provided inside the curtain wall decorative strip 3. The end of the threaded rod 8 away from the pulling block 7 is movably installed in the internal threaded fastening knob 10, and the internal threaded fastening knob 10 is movably installed on the curtain wall decorative strip 3 through a rotating shaft. The end of the internal threaded fastening knob 10 away from the threaded rod 8 passes through the mechanism cabin 9 and is exposed to the outside of the curtain wall decorative strip 3. The upper and lower threaded rods 8 are also provided with desiccant through holes 11, and the threaded rod 8 is movably inserted at the bottom of the desiccant storage tank 12. The mechanism cabin 9 is respectively provided with a discharge hole 13 and a feed hole 14 connected to the recess 6, and a desiccant blocking strip 15 is provided on the inner side of the recess 6 at the bottom of the feed hole 14. The desiccant blocking strip 15 blocks the desiccant from continuing to fall, ensuring that the desiccant accumulates above the feed hole 14, thereby ensuring the circulation of the desiccant. A lifting path 16 is provided in the mechanism cabin 9, and a lifting impeller 17 is movably provided in the lifting path 16. The lifting impeller 17 is meshed with the bevel gear blade 19 through the bevel gear 18. The impeller of the bevel gear blade 19 passes through the mechanism cabin 9 and is exposed to the outside of the curtain wall decorative strip 3. A lifting hole 20 is provided at the bottom of the lifting path 16, and a through hole 21 connected to the discharge hole 13 is provided at the upper part of the lifting path 16. The upper and lower pulling blocks 7 are movably clamped in the mounting groove 22 of the base 2, and a mounting groove sealing rubber pad 23 is provided in the recess 6. Sealing rubber pads 24 are provided at the contact points between the two sides of the recess 6 and the glass curtain wall 5, and a desiccant circulation gap 25 is formed between the curtain wall decorative strip 3 and the base 2.

[0026] When it is necessary to install the curtain wall decorative strip 3, the upper and lower pulling blocks 7 are vertically inserted into the installation groove 22 of the base 2, and the internal threaded fastening knob 10 is rotated by the hexagonal wrench. The rotation of the internal threaded fastening knob 10 drives the threaded rod 8 to rotate, and the rotation of the threaded rod 8 drives the pulling block 7 to rotate. When the pulling block 7 rotates, it is limited by the inner diameter of the installation groove 22 and is stuck in the installation groove 22. As the hexagonal wrench continues to rotate, the pulling block 7 does not rotate with it. At this time, the internal threaded fastening knob 10 rotates relative to the threaded rod 8. Since the internal threaded fastening knob 10 and the threaded rod 8 are threadedly connected, when the internal threaded fastening knob 10 is rotated, the threaded rod 8 drives the pulling block 7 to move toward the side close to the internal threaded fastening knob 10, so that the curtain wall decorative strip 3 is pulled toward the side close to the base 2 by the pulling block 7, and the two are firmly fixed. Firmly fixed and synchronous, in order to prevent the desiccant from spilling during the installation process and being unable to fill the desiccant circulation gap 25, the bottom of the desiccant storage tank 12 is closed by the threaded rod 8. When the threaded rod 8 rotates during the installation process and moves toward the side of the internal thread tightening knob 10, the desiccant through hole 11 on the threaded rod 8 is extended into the desiccant storage tank 12, thereby guiding the desiccant inside the desiccant storage tank 12 to fall into the bottom of the mechanism cabin 9, and the bevel gear fan blades 19 are used to drive the lifting impeller 17 to rotate, so as to lift the desiccant at the bottom of the mechanism cabin 9 and enter the desiccant circulation gap 25 through the discharge hole 13. The desiccant is circulated by using wind energy to provide power, ensuring that the desiccant circulation gap 25 can fully absorb the water vapor entering it, and further ensuring the stability of the base 2 and the internal structure.

[0027] As a preferred embodiment, the contact surfaces of the curtain wall support 1 and the base 2 with the glass curtain wall 5 are all installed with waterproof seals 26, which play a role of buffering and isolation.

[0028] As a preferred embodiment, sealing pads 27 are fixedly provided at the upper and lower ends of the curtain wall decorative strip 3, and are tightly connected to the upper and lower curtain wall decorative strips 3 through shock-absorbing pads.

[0029] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
