Description

Technical Field

[0001] This utility model belongs to the field of curtain wall structure technology, and in particular relates to a fireproof structure for curtain walls. Background Technology

[0002] In the field of building curtain wall engineering, fire-resistant curtain walls are a key component for improving building fire safety. Their installation stability and fire resistance reliability directly determine the overall safety performance of the building. Therefore, fire-resistant structures need to be considered when constructing curtain walls.

[0003] Chinese patent CN221030829U discloses a curtain wall structure with a fireproof structure. Through the installation and clamping components of the main mechanism (hand crank, double-sided threaded rod, positioning nut, etc.), rotating the hand crank can drive the fireproof metal plate to clamp the curtain wall body. With the help of the limit bolts to lock the hand crank, the curtain wall can be installed quickly. At the same time, the multi-layer fireproof mechanism meets the basic fire protection requirements.

[0004] The aforementioned patent has the following problems: This patent has several drawbacks in its application. Specifically, it relies solely on the threaded connection between the double-sided threaded rod and the positioning nut, and the clearance fit between the limiting bolt and the limiting hole for fixation, lacking anti-loosening and secondary locking designs. In outdoor use, the curtain wall is affected by wind pressure vibration and temperature changes, causing the threads to easily develop gaps due to vibration, resulting in a decrease in clamping force. The gap between the limiting bolt and the hole wall is also prone to bolt displacement and threaded rod rotation due to vibration, ultimately causing the curtain wall to loosen and shift. This not only affects installation accuracy but also widens gaps, weakens fire resistance, and shortens service life. Therefore, we propose a fire-resistant structure for curtain walls. Utility Model Content

[0005] The purpose of this utility model is to provide a fireproof structure for curtain walls to solve the problems mentioned in the background art.

[0006] In view of this, the present invention provides a fireproof structure for a curtain wall, including an installation plate, wherein an insulation board and a fireproof board are sequentially arranged on one side of the installation plate, and a curtain wall body is arranged on one side of the fireproof board; The through-frame has mounting holes on the surface of the mounting plate, and the through-frame is fixedly installed in the mounting holes. Opening and closing round blocks are fixedly installed at both ends of the through-frame. Multiple rotating openings are opened on the side of the opening and closing round blocks, and a frame is rotatably installed in each of the multiple rotating openings. A connecting hole is opened at the other end of each of the multiple frames. Multiple through holes are opened on one side of the mounting plate, insulation board, and fireproof board. The same through bolt is fixedly installed on two of the connecting holes. The through bolt passes through the through holes in the mounting plate, insulation board, and fireproof board in sequence.

[0007] In this technical solution, the mounting plate serves as the foundation for connection with the building structure. Insulation and fireproof boards are sequentially installed on one side of the mounting plate, with the curtain wall body positioned outside the fireproof board, forming a multi-layered composite structure. A mounting hole is located at the center of the mounting plate's surface, and a through-frame is fixedly installed within this hole. Opening and closing circular blocks are fixedly installed at both ends of the through-frame. Each opening and closing circular block has four equally spaced rotating openings on its side. One end of multiple frames is rotatably installed within these rotating openings via a pivot, allowing the frames to expand or contract like fan ribs around the opening and closing circular blocks, facilitating the insertion of the insulation and fireproof boards. Multiple through holes are located on one side of the mounting plate, insulation board, and fireproof board. These holes are aligned during stacking, and a single through bolt is fixedly installed on the connecting holes of two opposing frames. This through bolt passes sequentially through the aligned through holes in the mounting plate, insulation board, and fireproof board, locking the multi-layered structure together. This effectively resists external forces such as outdoor wind vibration and temperature deformation, preventing relative displacement between layers and improving structural stability.

[0008] In the above technical solution, furthermore, multiple extension tubes are fixedly installed on the frame near the fireproof board and communicate with the connection holes. Multiple connecting holes are opened on one side of the curtain wall body. Connecting bolts are rotatably installed in the connecting holes and the connecting bolts are screwed into the extension tubes.

[0009] In this technical solution, after the fireproof structure is tightened with through bolts, the curtain wall body is attached to the outside of the fireproof board. Then, connecting bolts are screwed in from the outside of the curtain wall body, passing through the connecting holes in the curtain wall body, and finally screwed into the extension tubes on the frame, thereby firmly fixing the curtain wall body to the fireproof structure, which facilitates the installation, adjustment, and subsequent maintenance and replacement of the curtain wall body.

[0010] In the above technical solution, further, a misalignment block is rotatably installed on one side of the opening and closing circular block, and a plurality of misalignment openings are provided on one side of the misalignment block. The size of the misalignment opening is the same as the size of the rotating opening. A positioning bolt is provided on the surface of the misalignment block, and two positioning holes are provided on one side of the opening and closing circular block. The positioning bolt is screwed into one of the positioning holes.

[0011] In this technical solution, a misalignment block is rotatably mounted on one side of the opening / closing circular block via a bearing. Multiple misalignment openings are provided on one side of the misalignment block, the size and position of which correspond to the rotation openings on the opening / closing circular block. The two positioning holes are typically 45 degrees apart. After the frame is fully extended and the through bolts are tightened, the frame needs to be locked to prevent rotation. At this point, the positioning bolts are loosened, and the misalignment block is rotated, causing its misalignment openings to align with the rotation openings on the opening / closing circular block. The solid part of the misalignment block then blocks the rotation path of the frame, preventing it from retracting. The positioning bolts are then screwed into the corresponding positioning hole on the opening / closing circular block, fixing the misalignment block in this locked position. This achieves absolute locking of the frame, preventing accidental rotation and loosening due to vibration or other reasons, providing double protection.

[0012] In the above technical solution, two protective sealing edges are further fitted onto the side of the mounting plate, and the two protective sealing edges are fixedly connected by bolts.

[0013] In this technical solution, after all panels and the curtain wall body are installed, the protective edge is fastened to the side of the assembly and then secured with bolts, effectively sealing the joints between the panels, preventing rainwater and dust from entering the interior, and protecting the insulation material and internal structure.

[0014] In the above technical solution, the mounting plate is made of aluminum alloy, and a fixing bracket is fixedly installed on one side of the mounting plate.

[0015] In this technical solution, aluminum alloy is lightweight and has high strength, which helps to reduce the overall structural weight while ensuring strength; the aluminum alloy mounting plate is fixed to the main building structure by a fixing frame.

[0016] In the above technical solution, the insulation board is further made of rock wool.

[0017] In this technical solution, rock wool is a highly efficient thermal insulation and fireproof material that can effectively reduce building energy consumption.

[0018] In the above technical solution, the fireproof board material is a metal composite fireproof board.

[0019] In this technical solution, metal composite fireproof boards typically have a high fire resistance rating, effectively preventing flame penetration and heat transfer, and providing sufficient fire isolation time for the building.

[0020] The beneficial effects of this utility model are: 1. The fireproof structure of this curtain wall consists of a through-frame consisting of a stacked mounting plate, insulation board, and fireproof board, which extends to the other side of the fireproof board. The through holes at the four vertices of the mounting plate, insulation board, and fireproof board are aligned. Then, the four frames on the opening and closing circular blocks on both sides of the through-frame are unfolded in sequence, aligning the connecting holes with the through holes. The through bolts are then passed through the connecting holes and the through holes and connected to the connecting holes on the other side of the frame. Finally, the layers are bolted together to lock the multi-layer structure together. This effectively resists the influence of external forces such as outdoor wind vibration and temperature deformation, prevents relative displacement between layers, and improves structural stability.

[0021] 2. The fireproof structure of this curtain wall, by loosening the positioning bolts and rotating the misalignment block, makes its misalignment opening separate from the rotation opening on the opening and closing round block. Then, by screwing the positioning bolts into another corresponding positioning hole on the opening and closing round block, the misalignment block is fixed in this locking position, which achieves absolute locking of the frame and prevents it from accidentally rotating and loosening due to vibration or other reasons, providing double insurance.

[0026] Example 1: This example provides a fireproof structure for a curtain wall, including a mounting plate 3. An insulation board 7 and a fireproof board 8 are sequentially arranged on one side of the mounting plate 3, and a curtain wall body 1 is arranged on one side of the fireproof board 8. The through frame 10 has mounting holes on the surface of the mounting plate 3. The through frame 10 is fixedly installed in the mounting holes. Opening and closing round blocks 11 are fixedly installed at both ends of the through frame 10. Multiple rotating openings are opened on the side of the opening and closing round blocks 11. A frame 5 is rotatably installed in each of the multiple rotating openings. A connecting hole is opened at the other end of each of the multiple frames 5. Multiple through holes are opened on one side of the mounting plate 3, the insulation board 7, and the fireproof board 8. The same through bolt 6 is fixedly installed on two connecting holes. The through bolt 6 passes through the through holes on the mounting plate 3, the insulation board 7, and the fireproof board 8 in sequence.

[0027] Among them, the mounting plate 3 serves as the base for connecting with the main building. On one side of the mounting plate 3, insulation board 7 and fireproof board 8 are arranged in sequence. The curtain wall body 1 is arranged on the outside of the fireproof board 8, forming a multi-layer composite structure. An installation hole is opened at the center point of the surface of the mounting plate 3. The through frame 10 is fixedly installed in this installation hole. Both ends of the through frame 10 are fixedly installed with opening and closing round blocks 11. Each opening and closing round block 11 has four rotating openings with equal angular spacing on its side. One end of multiple frames 5 is rotatably installed in the rotating opening through a rotating shaft, so that the frames 5 can be unfolded or retracted around the opening and closing round blocks 11 like fan ribs, which facilitates the insertion of insulation board 7 and fireproof board 8. Multiple through holes are opened on one side of the mounting plate 3, insulation board 7, and fireproof board 8. These holes are aligned when stacked. The same through bolt 6 is fixedly installed on the connecting holes on two opposite frames 5. The through bolt 6 passes through the aligned through holes on the mounting plate 3, insulation board 7, and fireproof board 8 in sequence, locking the multi-layer structure together. This effectively resists the influence of external forces such as outdoor wind vibration and temperature deformation, prevents relative displacement between layers, and improves structural stability.

In addition to the technical solutions of the above examples, it also has the following technical features: multiple frame members 5 near the fireproof board 8 are fixedly installed with extension screw tubes 16 and connected to connection holes. Multiple connecting holes are opened on one side of the curtain wall body 1. Connecting bolts 9 are rotatably installed in the connecting holes. The connecting bolts 9 are screwed into the extension screw tubes 16.

[0029] After the fireproof structure is locked in place by the through bolts 6, the curtain wall body 1 is pressed against the outside of the fireproof board 8. Then, the connecting bolts 9 are screwed in from the outside of the curtain wall body 1, so that they pass through the connecting holes of the curtain wall body 1 and are finally screwed into the extension tubes 16 on the frame 5, thereby firmly fixing the curtain wall body 1 to the fireproof structure, which facilitates the installation, adjustment and subsequent maintenance and replacement of the curtain wall body 1.

Multiple misalignment openings 15 are provided on one side of the misalignment block 13. The size and position of the misalignment openings 15 correspond to the rotation openings on the opening / closing block 11. The two positioning holes 12 are typically 45 degrees apart. After the frame 5 is fully extended and the through bolt 6 is tightened, the frame 5 needs to be locked to prevent rotation. At this time, the positioning bolt 14 is loosened, and the misalignment block 13 is rotated, causing its misalignment openings 15 to be misaligned with the rotation openings on the opening / closing block 11. The solid part of the misalignment block 13 will then block the rotation path of the frame 5, preventing the frame 5 from retracting. Then, the positioning bolt 14 is screwed into the corresponding positioning hole 12 on the opening / closing block 11, fixing the misalignment block 13 in this locked position. This achieves absolute locking of the frame 5, preventing accidental rotation and loosening due to vibration or other reasons, providing double protection.

In addition to the technical solutions of the above examples, it also has the following technical features: two protective edge seals 2 are fitted to the side of the mounting plate 3, and the two protective edge seals 2 are fixedly connected by bolts.

[0033] Once all panels and the curtain wall body 1 are installed, the protective edge seal 2 is fastened to the side of the assembly and then secured with bolts to effectively seal the joints between the panels, prevent rainwater and dust from entering the interior, and protect the insulation material and internal structure.

In addition to the technical solutions of the above examples, it also has the following technical features: the mounting plate 3 is made of aluminum alloy, and a fixing bracket 4 is fixedly installed on one side of the mounting plate 3.
