DETAILED DESCRIPTION

[0025] See also Figure 1-5 A large-facade unit curtain wall for a public building comprises a keel frame 1 and a plurality of unit curtain walls, the keel frame 1 is provided with a plurality of mounting grooves, each unit curtain wall is installed in one mounting groove, the size of the keel frame 1 and the number of mounting grooves can be set according to demand, the unit curtain wall comprises a curtain wall base 3, a curtain wall panel 4 is arranged on the back of the curtain wall base 3, a working cavity is opened inside the curtain wall base 3, a fixing component 8 is arranged inside the working cavity, and is used to fix the curtain wall base 3 inside the mounting groove;

[0026] The fixing assembly 8 includes two groups of mounting plates 81 fixedly installed inside the working chamber, each group of mounting plates 81 has two, and a rotating shaft 82 is rotatably installed on each group of mounting plates 81. Both ends of the rotating shaft 82 are sleeved with fixing sleeves 86, and one end of the two fixing sleeves 86 extends to the outside of the curtain wall base 3. The surface of the longitudinal beam of the keel frame 1 is provided with a plurality of fixing grooves 2, and the surfaces of the fixing sleeves 86 and the fixing grooves 2 are provided with corresponding threads. A transmission wheel 84 is fixedly installed on the surface of the rotating shaft 82, and a transmission chain 85 is installed between the two transmission wheels 84.

[0027] See also Figure 4 Two drive shafts 9 are rotatably installed inside the working chamber. The position of the drive shaft 9 corresponds to the rotating shaft 82. One end of the drive shaft 9 is fixedly connected to a worm 10. A worm wheel 83 is provided on the outer surface of the rotating shaft 82. The worm wheel 83 meshes with the worm 10. The other end of the drive shaft 9 extends to the outside of the curtain wall base 3. The other end surface of the drive shaft 9 is provided with an inner hexagonal groove 11.

[0028] By inserting the hexagonal wrench into the hexagonal slot 11, the drive shaft 9 is driven to rotate, and the drive shaft 9 drives the worm 10 to rotate. The worm 10 drives the rotating shaft 82 to rotate by driving the worm wheel 83. The rotating shaft 82 drives another transmission shaft 82 to rotate through the transmission wheel 84 and the transmission wheel 85. The two transmission shafts 82 rotate at the same time, which can drive the fixed sleeves 86 at both ends to extend and rotate, and insert them into the fixed slots 2 on the keel frame 1, so that the unit curtain wall is fixedly installed in the installation slot. The installation method is simple and only one rotation is required to complete the installation, which greatly improves the installation efficiency.

[0029] Among them, see Figure 5 , the interior of the fixed sleeve 86 is fixedly connected with a spring 2 87, one end of the spring 2 87 is fixedly connected to the rotating shaft 82, a slide groove 88 is provided on the surface of the rotating shaft 82, and a limit slider 89 is fixedly installed on the inner wall of the fixed sleeve 86, and the limit slider 89 is slidably arranged inside the slide groove 88. When the rotating shaft 82 drives the fixed sleeve 86 to rotate at the fixed groove 2, the spring 2 87 will push the fixed sleeve 86 to slide outward. The two cooperate to facilitate the threaded sleeve 86 to be screwed and assembled inside the fixed groove 2. The limit slider 89 is used to prevent the threaded sleeve 86 and the rotating shaft 82 from rotating relative to each other, which affects the normal operation of the device.

[0030] See also Figure 3A support frame 5 is fixedly installed at the back edge of the curtain wall base 3, and a sliding frame 6 is fixedly installed on the surface of the curtain wall panel 4 facing the curtain wall base 3.

The springs 7 are all arranged on the inner side of the sliding frame 6, and one end of the spring 7 is fixedly connected to the surface of the curtain wall panel 4. The contact surface between the support frame 5 and the sliding frame 6 is a rough friction surface.

[0031] When the device is installed and a collision occurs during use, the curtain wall panel 4 will be driven to move toward the curtain wall base 3, and the curtain wall panel 4 will drive the sliding frame 6 to move on the inner wall of the support frame 5, rubbing against the inner wall of the support frame 5, and cooperating with the spring 7 to absorb the energy generated by the collision, thereby improving the impact resistance and load-bearing effect of the device and improving the safety of the device.

[0032] Among them, the edges of the curtain wall panels 4 extend to the outside of the curtain wall base 3, the upper and lower edges of the curtain wall panels 4 extend to half the width of the crossbeam on the keel frame 1, and the left and right edges of the curtain wall panels 4 extend to half the width of the longitudinal beam on the keel frame 1. When the unit curtain wall is filled in the installation groove on the keel frame 1, the edges of the curtain wall panels 4 can fit together, reducing the gap between the curtain wall panels 4 and improving the aesthetics of the device.

[0033] Working principle: When installing the large-facade unit curtain wall for public buildings, first assemble the keel frame 1 of a predetermined size according to the needs, then fill the unit curtain wall into the installation groove on the keel frame 1, and insert the hexagonal wrench into the hexagonal groove 11 to drive the drive shaft 9 to rotate, and the drive shaft 9 drives the rotating shaft 82 to rotate. The rotating shaft 82 drives another transmission shaft 82 to rotate through the transmission wheel 84 and the transmission wheel 85. The two transmission shafts 82 rotate at the same time, which can drive the fixed sleeves 86 at both ends to extend and rotate, and insert them into the fixed groove 2 on the keel frame 1, so that the unit curtain wall is fixedly installed in the installation groove. The installation method is simple, and only one rotation is required to complete the installation, which greatly improves the installation efficiency.

[0034] Two drive shafts 9 are arranged on each curtain wall base 3, and the two drive shafts 9 are arranged on the upper and lower sides of the curtain wall base 3. Any one of the drive shafts 9 can be rotated to complete installation and disassembly, which is convenient for the staff to select the drive shaft 9 of appropriate height according to their own needs for operation. The staff can work at a comfortable height, further improving the work efficiency of the staff;

[0035] When the device is installed and a collision occurs during use, the curtain wall panel 4 will be driven to move toward the curtain wall base 3, and the curtain wall panel 4 will drive the sliding frame 6 to move on the inner wall of the support frame 5, rubbing against the inner wall of the support frame 5, and cooperating with the spring 7 to absorb the energy generated by the collision, thereby improving the impact resistance and load-bearing effect of the device and improving the safety of the device.
