[0014] The present invention also discloses a method for connecting a prefabricated steel structure building curtain wall, which specifically comprises the following steps:

[0015] S1. Several prefabricated outer frames are installed on the outer wall in order through the perforated back plate and bolts, and then the threaded rod is screwed. When the threaded rod rotates, the first threaded sleeve on its surface will move forward, and the first threaded sleeve will synchronously drive the two delayed vertical plates to move. The bottom delayed vertical plate first moves against the front side of the inner cavity of the small-span U-shaped frame, and drives the small-span U-shaped frame and the bottom U-shaped receiving frame to move forward. Along with the movement of the bottom U-shaped receiving frame, the top delayed vertical plate also successively abuts against the front side of the inner cavity of the large-span U-shaped frame, and lags to drive the top U-shaped slide plate and the U-shaped receiving frame to move forward. When the two upper and lower U-shaped receiving frames on the same side move, they move in a stepped staggered and orderly manner until the two U-shaped receiving frames on the same side move out of the inside of the installation slot;

[0016] S2. When the threaded rod is twisted to cause the first threaded sleeve to move forward, the second threaded sleeve on the surface of the threaded rod also moves forward successively. When the second threaded sleeve moves forward, it will move ahead of the U-shaped receiving frame, causing the second threaded sleeve to carry the front ring edge and the front sealing strip in advance and separate from the close fit with the U-shaped receiving frame, leaving enough smooth space for the subsequent placement of the curtain wall panel;

[0017] S3. After the curtain wall panels are moved forward out of the front side of the installation slot, the operator sequentially places multiple curtain wall panels into the U-shaped receiving frame. During the process of lowering the curtain wall panels into the U-shaped receiving frame, the two sides of the curtain wall panels will laterally squeeze the tilt pressing block, so that after the curtain wall panels are placed in place, the tilt pressing block is easy to reset and limit the top of the curtain wall panels;

[0018] S4, seal and reinstall. Finally, the operator reversely rotates the threaded rod to make the first threaded sleeve carry two delayed vertical plates, and gradually push the rear sides of the inner cavities of the large-span U-frame and the small-span U-frame respectively, so that the large-span U-frame and the small-span U-frame respectively drive the U-shaped receiving frame and the curtain wall panel to move backward, until the rear side of the curtain wall panel is sealed with the rear sealing strip. During the reverse rotation of the threaded rod, the second threaded sleeve simultaneously drives the front ring edge and the front sealing strip to fit tightly against the curtain wall panel inside the U-shaped receiving frame, and finally seals and fits the front and rear sides of the curtain wall panel together with the rear sealing strip. Finally, the front ring edge is subsequently reinforced through the threaded fixing cooperation of the perforated ear plate, the threaded hole and the fastening bolt.

[0019] Preferably, a rubber sealing ring gasket matched with the front side of the prefabricated outer frame is fixedly provided on the rear side of the front ring edge in S4.

[0020] The present invention provides a prefabricated steel structure building curtain wall connection device and method. Compared with the existing technology, it has the following beneficial effects:

[0021] (1) The assembly-type steel structure building curtain wall connection device and method pre-prepare a prefabricated outer frame, and set a push-pull mechanism, a gradient expansion mechanism and a self-sealing mechanism inside the prefabricated outer frame, so that when the curtain wall panels in the prefabricated outer frame are installed, the push-pull mechanism, the gradient expansion mechanism and the self-sealing mechanism can be coordinated to quickly complete batch receiving and placement, and the U-shaped receiving frames of different receiving mechanisms are arranged in a gradient manner to facilitate barrier-free placement of the curtain wall panels, and the front and rear sides of the curtain wall panels are sealed and fitted simultaneously, so as to achieve the effect of time-saving and efficient installation.

[0022] (2) The assembly type steel structure building curtain wall connection device and method elastically arranges angled pressure blocks on both sides of the inner cavity of the U-shaped receiving frame, so that when the curtain wall panel is assembled inside the U-shaped receiving frame, the assembly position of the curtain wall panel can be positioned and locked by elastic expansion and contraction of the angled pressure blocks.

[0023] (3) The assembly-type steel structure building curtain wall connection device and method, by arranging a push-pull plate on the top of the angled pressure block, and opening movable long grooves that are slidably matched on both sides of the top of the U-shaped receiving frame, makes it easy for the angled pressure block to slide and cooperate with the push-pull plate and the movable long groove, so as to achieve the effect of easy manual operation, so as to facilitate the subsequent disassembly and assembly of the curtain wall panel.

[0024] (4) The assembly-type steel structure building curtain wall connection device and method, by arranging a perforated ear plate, threaded holes and fastening bolts between the front bezel and the prefabricated outer frame, enables the front sealing strip on the rear side of the front bezel to be sealed and attached to the front side of the curtain wall panel, and can also be used to facilitate the reinforcement of the position of the front bezel and the front sealing strip after they are moved through the cooperation of the perforated ear plate, threaded holes and fastening bolts.

[0054] The present invention also discloses a method for connecting a prefabricated steel structure building curtain wall, which specifically comprises the following steps:

[0055] S1. Several prefabricated outer frames 1 are installed on the outer wall in order through the perforated back plate 18 and bolts, and then the threaded rod 505 is screwed. When the threaded rod 505 rotates, the first threaded sleeve 506 on its surface will move forward, and the first threaded sleeve 506 will synchronously drive the two delayed vertical plates 507 to move. The bottom delayed vertical plate 507 moves and first abuts against the front side of the inner cavity of the small-span U-shaped frame 603, and drives the small-span U-shaped frame 603 and the bottom U-shaped receiving frame 503 to move forward.

When the two upper and lower U-shaped receiving frames 503 on the same side move, they move in a stepped staggered and orderly manner until the two U-shaped receiving frames 503 on the same side move out of the installation slot 2.

[0056] S2, when the threaded rod 505 is screwed to cause the first threaded sleeve 506 to move forward, the second threaded sleeve 703 on the surface of the threaded rod 505 also moves forward successively. When the second threaded sleeve 703 moves forward, it will move ahead of the U-shaped receiving frame 503, causing the second threaded sleeve 703 to carry the front edge 701 and the front sealing strip 702 in advance to break away from the close fit with the U-shaped receiving frame 503, leaving enough smooth space for the subsequent placement of the curtain wall panel 504;

[0057] S3, after the curtain wall panel 504 moves forward out of the front side of the installation slot 2, the operator sequentially places multiple curtain wall panels 504 into the U-shaped receiving frame 503. During the process of lowering the curtain wall panel 504 into the U-shaped receiving frame 503, the two curtain wall panels 504 will laterally squeeze the tilt pressing block 12, so that after the curtain wall panel 504 is placed in place, the tilt pressing block 12 is easy to reset and limit the top of the curtain wall panel 504;

[0058] S4, seal back, finally the operator reversely screws the threaded rod 505, prompting the first threaded sleeve 506 to carry the two delay vertical plates 507, gradually push the rear side of the inner cavity of the large-span U-shaped frame 602 and the small-span U-shaped frame 603, respectively, prompting the large-span U-shaped frame 602 and the small-span U-shaped frame 603 to respectively drive the U-shaped receiving frame 503 and the curtain wall panel 504 to move backward, until the rear side of the curtain wall panel 504 is sealed and attached to the rear sealing strip 4. During the reverse screwing of the threaded rod 505, the second threaded sleeve 506 is screwed to the rear side of the curtain wall panel 504, and the second threaded sleeve 506 is screwed to the rear side of the curtain wall panel 504. The grooved sleeve 703 synchronously drives the front ring edge 701 and the front sealing strip 702 to fit tightly against the curtain wall panel 504 inside the U-shaped receiving frame 503, and finally seals the front and rear sides of the curtain wall panel 504 together with the rear sealing strip 4. Finally, the front ring edge 701 is subsequently reinforced by threaded fixing of the perforated ear plate 15, the threaded hole 16 and the fastening bolt 17, wherein the rear side of the front ring edge 701 is fixedly provided with a rubber sealing ring gasket used in conjunction with the front side of the prefabricated outer frame 1.
