Description

Technical Field

[0001] This application belongs to the technical field of curtain walls and relates to a fireproof curtain wall system. Background Art

[0002] A glass curtain wall refers to an exterior enclosure structure or decorative structure of a building whose supporting structure system can have a certain displacement ability relative to the main structure and does not share the actions borne by the main structure.

[0003] According to the installation method, glass curtain walls are divided into exposed-frame curtain walls and hidden-frame curtain walls. A hidden-frame glass curtain wall bonds the glass to the aluminum frame with silicone structural sealant. The aluminum frame is hidden behind the glass, and the bonding between the glass and the aluminum frame depends entirely on the structural sealant. The structural sealant has to bear the self-weight of the glass, the wind load and seismic actions borne by the glass, as well as the influence of temperature changes. Therefore, the structural sealant is a key link in the safety of hidden-frame curtain walls.

[0004] When a building catches fire, the structural sealant is prone to melting due to high temperature, resulting in the bonding failure between the glass and the aluminum frame, and the glass falling off the aluminum frame, causing potential safety hazards. Summary of the Invention

[0005] In order to improve the safety of the curtain wall, this application provides a fireproof curtain wall system.

[0006] The fireproof curtain wall system provided by this application adopts the following technical solutions:

[0007] A fireproof curtain wall system includes a fixed frame assembly and a glass assembly. The glass assembly is bonded to the fixed frame assembly with structural sealant. At the bottom of the fixed frame assembly, a number of angle irons are arranged at intervals along the horizontal direction. The angle irons are in contact with the bottom of the glass assembly. The angle irons are provided with sliding grooves along the horizontal direction. A supporting plate is slidably arranged in the sliding grooves.

[0008] By adopting the above technical solutions, the glass assembly is fixed to the fixed frame assembly with structural sealant. The angle irons are in contact with the bottom of the glass assembly to form a support, reducing the external force on the structural sealant and improving the connection stability. When a fire occurs, the shape memory alloy member deforms when heated, sliding the supporting plate out of the sliding groove of the angle iron, so that the supporting plate is in contact with the bottom of the glass assembly to form a support, reducing the risk of the glass assembly falling due to the failure of the structural sealant caused by heat, and improving the safety of the curtain wall.

Detailed implementation manners

[0035] The following will further describe the present application in detail Figure 1-8 with reference to the attached drawings.

[0036] As Figure 1 , Figure 2 shown, the fireproof curtain wall system includes a fixed frame assembly 1 and a glass assembly 2, and the glass assembly 2 is bonded to the fixed frame assembly 1 through structural glue.

[0037] In this embodiment, the fixed frame assembly 1 includes a plurality of columns 11 and cross beams 12, the columns 11 and cross beams 12 are vertically distributed and fixedly connected, and the columns 11 are fixed on the steel frame 13.

[0038] As Figure 1 , Figure 3 shown, the fixed frame assembly 1 further includes a sub-frame 14, the sub-frame 14 is fixed on the columns 11 and cross beams 12 through a pressing plate 15, and sealing strips 16 are arranged between the sub-frame 14 and the columns 11 and cross beams 12.

[0039] The glass assembly 2 includes two glass bodies 21, a fixing glue 22 is arranged between the two glass bodies 21, and a fixing glue 22 is arranged between the glass body 21 close to the sub-frame 14 and the sub-frame 14.

[0040] As Figure 4 , Figure 5 shown, a plurality of angle irons 3 are arranged at intervals along the horizontal direction at the bottom of the fixed frame assembly 1, and the angle irons 3 are in contact with the bottom of the glass assembly 2.

[0041] In this embodiment, the angle iron 3 is L-shaped, a portion of which is fixed to the crossbeam 12 by bolts, and the other portion is bent and attached to the glass assembly 2 .

[0042] The angle iron 3 is provided with a slide groove 31 in the horizontal direction, a support plate 32 is slidably arranged in the slide groove 31, and a memory alloy part 33 is arranged between the support plate 32 and the angle iron 3. After being heated, the memory alloy part 33 can partially push the support plate 32 out of the slide groove 31, so that the support plate 32 is attached to the bottom of the glass assembly 2.

[0043] In order to improve the support stability of the support plate 32, a slot 34 is provided on the side of the angle iron 3 opposite to the chute 31, and the support plate 32 on the angle iron 3 adjacent to the slot 34 can slide into the slot 34. When a fire occurs, one end of the support plate 32 is located in the chute 31 of the angle iron 3, and the other end of the support plate 32 slides into the slot 34 of the angle iron 3 adjacent to it, so that both ends of the support plate 32 are supported and the support stability is improved.

[0044] Preferably, a mounting groove 35 is provided on one side of the support plate 32 close to the glass assembly 2, and a heat expansion block 36 is arranged in the mounting groove 35. There is a gap between the heat expansion block 36 and the inner wall of the slide groove 31. The thermal expansion coefficient of the heat expansion block 36 is smaller than the thermal expansion coefficient of the memory alloy part 33. The heat expansion block 36 can be attached to the glass assembly 2 after being heated.

[0045] When a fire occurs, the temperature gradually rises, and the memory alloy part 33 first undergoes a large deformation, pushing the support plate 32 out of the slide groove 31. Since the thermal expansion coefficient of the heat expansion block 36 is smaller than that of the memory alloy part 33, the expansion amount of the heat expansion block 36 is small at this time, and there is still a certain gap between the heat expansion block 36 and the inner wall of the slide groove 31, so it can be pushed out of the slide groove 31 relatively smoothly. The temperature continues to rise, the heat expansion block 36 expands, and sticks to the glass component 2 to form a support.

[0046] Preferably, the angle iron 3 and the support plate 32 can be designed as two groups, which are respectively located above and below the glass assembly 2. After the heat expansion block 36 expands, it can clamp the glass assembly 2 to improve stability.

[0047] In order to adapt to different installation accuracies or compensate for part errors, an adjustment groove 37 is provided on the side of the support plate 32 away from the installation groove 35. A threaded hole communicating with the installation groove 35 is provided at the bottom of the adjustment groove 37. An adjustment bolt 38 is threadedly connected to the threaded hole. One end of the adjustment bolt 38 is in contact with the heat expansion block 36, and the other end is located in the adjustment groove 37. Rotating the adjustment bolt 38 can drive the adjustment bolt 38 to move, push the heat expansion block 36 to move, and compensate for the error.

[0048] Preferably, some of the vertical columns 11 and the cross beams 12 are provided with lamp beads. Each lamp bead is connected in series to form a lamp belt in the shape of "SOS". The lamp belt is connected to a power source. One end of the support plate 32 facing away from the sliding groove 31 is provided with a pressure sensor 39, and the pressure sensor 39 is connected to the controller of the power source. When a fire occurs, the shape memory alloy member 33 deforms, pushing out the support plate 32. The pressure sensor 39 at the end of the support plate 32 contacts the inner wall of the card slot 34 of the adjacent angle iron 3, transmitting a signal to the controller connected to the power source to control the lamp belt to turn on, forming an "SOS" pattern to prompt passers-by for rescue.

[0053] , a water tank 4 is provided on one side of the fixed frame assembly 1 facing away from the glass assembly 2. A piston 41 is slidably arranged in the water tank 4 in the horizontal direction. A water chamber 42 is formed between the piston 41 and the inner wall of the water tank 4. A spray head communicating with the water chamber 42 is provided outside the water tank 4. The spraying direction of the spray head faces the glass assembly 2. A transmission member 43 for synchronously moving the two is provided between the support plate 32 and the piston 41.

[0050] In this embodiment, the fixed frame assembly 1 is provided with a strip-shaped hole 44, and the strip-shaped hole 44 is arranged in the horizontal direction.

[0051] Preferably, the strip-shaped hole 44 is opened on the cross beam 12 and penetrates through the front end and the rear end of the cross beam 12. One end of the transmission member 43 is fixedly connected to the support plate 32, and the other end of the transmission member 43 passes through the strip-shaped hole 44 and is fixedly connected to the piston 41. The transmission member 43 can slide in the horizontal direction. The transmission member 43 can be designed as a transmission rod or a transmission bracket. When the support plate 32 moves, the piston 41 is driven to move through the transmission member 43, so that the piston 41 compresses the water chamber 42.

[0052] Preferably, the water tank 4 and the spray head are designed as two groups, which are respectively located above and below the glass assembly 2.

[0053] The working principle of this embodiment is as follows: When a fire occurs, the shape memory alloy member 33 is heated and deformed, sliding the support plate 32 out of the sliding groove 31 of the angle iron 3. The heat-expanded block 36 on the support plate 32 expands and adheres to the glass assembly 2 to form a support. While the support plate 32 moves, the piston 41 is driven to move through the transmission member 43, so that the piston 41 compresses the water chamber 42, and the cooling water is sprayed onto the surface of the glass assembly 2 through the spray head.
