Description

Technical Field

[0001] This utility model relates to the field of building envelope technology, and in particular to a fireproof curtain wall. Background Technology

[0002] A curtain wall is the exterior wall cladding structure of a building. It is widely used in modern architecture, especially in large and high-rise buildings. It is usually hung on the exterior wall of the building like a curtain. Curtain walls not only have a decorative function, but also enhance the aesthetic appearance of the building.

[0003] Building curtain walls are the external envelope of buildings composed of metal components and glass panels. In the event of a fire, building curtain walls are easily broken after being burned or heated, and may even cause large-scale breakage accidents, resulting in "fire-igniting ducts". The fire spreads rapidly and can easily endanger the safety of surrounding buildings and people.

[0004] Therefore, this application provides a fireproof curtain wall to meet the requirements. Utility Model Content

[0005] The purpose of this utility model is to solve the problems existing in the above-mentioned background technology and to propose a fireproof curtain wall.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0007] A fireproof curtain wall includes: an aluminum alloy vertical frame, an aluminum alloy horizontal frame, a glass curtain wall, angle steel connectors, aluminum alloy hangers, clamps, a fire extinguishing agent storage tank, a nozzle, and a heat-sensing glass bulb. The surface of the aluminum alloy vertical frame is provided with detection holes. An aluminum alloy horizontal frame is horizontally installed at the side corner of the aluminum alloy vertical frame. The glass curtain wall is installed inside the aluminum alloy vertical and horizontal frames. An angle steel connector is installed on the back of the aluminum alloy horizontal frame. An aluminum alloy hanger is installed on the back of the aluminum alloy vertical frame. A clamp is installed at the other end of the aluminum alloy hanger. A fire extinguishing agent storage tank is installed inside the clamp. A nozzle is fixedly connected to the upper end of the fire extinguishing agent storage tank. A heat-sensing glass bulb is embedded at the end of the nozzle.

[0008] Preferably, the aluminum alloy vertical frame is provided with detection holes at both the top and bottom ends, and the detection holes are located at the corners where the aluminum alloy vertical frame and the aluminum alloy horizontal frame meet.

[0009] Preferably, the detection hole penetrates the surfaces of both ends of the aluminum alloy vertical frame, and the detection hole is arranged in multiple segments, with the front end of the detection hole being trumpet-shaped and the rear end being cylindrical.

[0010] Preferably, the aluminum alloy hanger is installed laterally at the rear end of the aluminum alloy vertical frame by bolts, and the clamp extends rearward to the lower inner end of the aluminum alloy horizontal frame.

[0011] Preferably, the extinguishing agent storage tank is equipped with two sets of aluminum alloy brackets and clamps, and the extinguishing agent storage tank is vertically installed in the two sets of clamps.

[0012] Preferably, the clamp is engaged with the aluminum alloy hanger, and the extinguishing agent storage tank contains dry powder extinguishing agent.

[0013] Preferably, the nozzle extends to the detection hole opening on the back of the aluminum alloy vertical frame, and the temperature-sensing glass ball is embedded in the detection hole.

[0014] Compared with the prior art, this utility model has at least the following beneficial effects:

[0015] In the above scheme, when the curtain wall is exposed to fire, the burning material burns on the surface of the curtain wall, and the aluminum alloy vertical frame heats up. When the temperature-sensitive glass ball embedded in the detection hole on the surface of the aluminum alloy vertical frame encounters the rising high-temperature gas, it expands as the temperature rises and decomposes into small fragments at high temperature. After the temperature-sensitive glass ball breaks, it releases the opening of the nozzle, causing the dry powder extinguishing agent in the extinguishing agent storage tank to be sprayed outward. After the dry powder extinguishing agent is sprayed out, it covers downward due to gravity, which can automatically extinguish the fire when it encounters a fire, extinguishing the fire on the surface of the curtain wall. This ensures that the curtain wall can effectively prevent the flames from spreading through the gap between the curtain wall and the main structure when a fire occurs, buying time for firefighters to carry out rescue and reducing the losses caused by the fire.

[0016] In the above solution, aluminum alloy hangers are installed on the back of the aluminum alloy vertical frame, and clamps are installed on the other end of the aluminum alloy hangers. The fire extinguishing agent storage tank is vertically installed in two sets of clamps. The clamps are engaged with the aluminum alloy hangers, and the clamps and the fire extinguishing agent storage tank can be directly removed from the aluminum alloy hangers. This makes it more convenient to maintain or replace the fire extinguishing agent storage tank, thus maintaining the fire resistance of the curtain wall for a long time. Attached Figure Description

[0027] like Figure 1 , Figure 2 , Figure 3 and Figure 4The fireproof curtain wall shown in this embodiment includes: an aluminum alloy vertical frame 1, an aluminum alloy horizontal frame 2, a glass curtain wall 3, an angle steel connector 4, an aluminum alloy hanger 5, a clamp 6, a fire extinguishing agent storage tank 7, a nozzle 8, and a temperature-sensing glass bulb 9. The surface of the aluminum alloy vertical frame 1 is provided with a detection hole 101. An aluminum alloy horizontal frame 2 is horizontally installed at the side corner of the aluminum alloy vertical frame 1. The glass curtain wall 3 is installed inside the aluminum alloy vertical frame 1 and the aluminum alloy horizontal frame 2. An angle steel connector 4 is installed on the back of the aluminum alloy horizontal frame 2. An aluminum alloy hanger 5 is installed on the back of the aluminum alloy vertical frame 1. A clamp 6 is installed at the other end of the aluminum alloy hanger 5. A fire extinguishing agent storage tank 7 is installed inside the clamp 6. A nozzle 8 is fixedly connected to the upper end of the fire extinguishing agent storage tank 7. A temperature-sensing glass bulb 9 is embedded at the end of the nozzle 8.

[0028] In this embodiment, both the upper and lower ends of the aluminum alloy vertical frame 1 are provided with detection holes 101, and the detection holes 101 are located at the corner connection between the aluminum alloy vertical frame 1 and the aluminum alloy horizontal frame 2, which makes the detection position more reasonable and allows spraying from the corner connection of the curtain wall to ensure the spraying area.

[0029] In this embodiment, the detection hole 101 penetrates the surfaces of both ends of the aluminum alloy vertical frame 1, and the detection hole 101 is arranged in multiple segments. The front end of the detection hole 101 is funnel-shaped, and the rear end of the detection hole 101 is cylindrical. This allows the front end of the detection hole 101, which expands outward in a funnel shape, to allow the dry powder extinguishing agent to diffuse outward when it is sprayed during spraying.

[0030] In this embodiment, the aluminum alloy hanger 5 is installed horizontally at the rear end of the aluminum alloy vertical frame 1 by bolts, and the clamp 6 extends backward to the lower inner end of the aluminum alloy horizontal frame 2, which can minimize the impact on the view of the glass curtain wall 3 and make it more aesthetically pleasing.

[0031] In this embodiment, the fire extinguishing agent storage tank 7 is equipped with two sets of aluminum alloy hangers 5 and clamps 6, and the fire extinguishing agent storage tank 7 is vertically installed in the two sets of clamps 6, making the installation of the fire extinguishing agent storage tank 7 more stable.

[0032] In this embodiment, the clamp 6 is engaged with the aluminum alloy hanger 5, and the fire extinguishing agent storage tank 7 contains dry powder fire extinguishing agent. The clamp 6 and the fire extinguishing agent storage tank 7 can be directly removed from the aluminum alloy hanger 5, making it more convenient to maintain or replace the fire extinguishing agent storage tank 7.

[0033] In this embodiment, the nozzle 8 extends to the opening of the detection hole 101 on the back of the aluminum alloy vertical frame 1, and the heat-sensitive glass ball 9 is embedded in the detection hole 101. When the curtain wall is in a fire, the burning material burns on the surface of the curtain wall, and the aluminum alloy vertical frame 1, made of metal, is heated. When the heat-sensitive glass ball 9 embedded in the detection hole 101 on the surface of the aluminum alloy vertical frame 1 encounters the rising high-temperature gas, the sealed liquid in the glass ball encounters the high-temperature gas and expands as the temperature rises. Under high temperature, the ball is decomposed into small fragments. After the heat-sensitive glass ball 9 breaks, it releases the opening of the nozzle 8, allowing the dry powder extinguishing agent in the extinguishing agent storage tank 7 to be sprayed outward. After the dry powder extinguishing agent is sprayed out, it covers downward due to gravity and can automatically extinguish the fire when it encounters a fire, extinguishing the fire on the surface of the curtain wall. This ensures that the curtain wall can effectively prevent the flames from spreading through the gap between the curtain wall and the main structure when a fire occurs, buying time for firefighters to carry out rescue and reducing the losses caused by the fire.

[0034] This utility model encompasses any substitutions, modifications, equivalent methods, and solutions made within the spirit and scope of this utility model.

Furthermore, to avoid unnecessary confusion regarding the essence of this utility model, well-known methods, processes, procedures, components, and circuits are not described in detail.

[0035] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
