Description

Technical Field

[0001] This utility model relates to the field of curtain wall technology, specifically a fireproof curtain wall. Background Technology

[0002] A curtain wall is a building envelope or decorative structure composed of a supporting structural system and panels. It has a certain displacement capacity relative to the main structure and does not share the load and action of the main structure. Its characteristics are that it has an independent and complete structural system, covers the main structure and has a certain degree of micro-movement capability. According to the supporting structural form, it can be divided into component type, unit type, etc., and according to the panel material, it can be divided into glass, metal and other types.

[0003] In practical use, the fireproof function of existing fireproof curtain walls mainly relies on fireproof materials to passively block the spread of fire. However, during prolonged high-temperature processes, the fire resistance limit of the materials will gradually fail, and the curtain wall glass is prone to breakage, which in turn can easily create fireproof gaps, allowing the fire to break through the original barrier and spread outward, making it difficult to stop the spread of fire. Therefore, a fireproof curtain wall is proposed to solve the above-mentioned problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a fireproof curtain wall that, when the curtain wall glass breaks, can provide secondary fire protection through the fireproof curtain, effectively preventing the spread of fire. This solves the problem that existing fireproof curtain walls, in actual use, mainly rely on fireproof materials to passively block the spread of fire. However, during prolonged high-temperature processes, the fire resistance limit of the materials gradually fails, easily leading to broken curtain wall glass and fireproof gaps. This allows the fire to break through the original barrier and spread outward, making it difficult to prevent the spread of fire.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A fireproof curtain wall includes two parallel steel structure supports and a curtain wall glass fixed between the two steel structure supports. A fixed shell located on the front side of the curtain wall glass is fixedly connected between the two steel structure supports. A rotating column that can rotate around an axis is provided on the inner side of the fixed shell. A counterweight is installed on the inner side of the fixed shell through a fuse. A fireproof curtain with its other end fixedly connected to the outer side of the rotating column is fixedly connected to the outer side of the counterweight. The width of the fireproof curtain matches the width of the curtain wall glass.

[0006] The beneficial effects of this utility model are: This fireproof curtain wall has the advantage that when the curtain wall glass is broken, the fireproof curtain can provide secondary protection against fire, effectively preventing the fire from spreading.

[0007] Based on the above technical solution, the present invention can be further improved as follows.

[0008] Furthermore, limit sliders are fixedly connected to both sides of the counterweight, and the limit sliders and the limit sliding holes on the inner side of the steel structure bracket form a sliding pair. A pushing component that contacts the top surface of the limit slider is fixedly connected to the inner side of the steel structure bracket.

[0009] The beneficial effect of adopting the above-mentioned further solution is that the limiting slider combined with the limiting sliding hole can improve the falling effect of the counterweight and effectively prevent the counterweight from shifting its position when falling.

[0010] Furthermore, the pushing assembly includes a fixed plate welded to the inner side of the steel structure support and a pushing spring fixedly connected to the outer side of the fixed plate, wherein the free end of the pushing spring is in contact with the top surface of the limiting slider.

[0011] The advantage of adopting the above-mentioned further solution is that the pushing component can push the counterweight block downward.

[0012] Furthermore, it also includes an auxiliary fixing component, which includes an auxiliary box fixedly connected between two steel structure supports, an auxiliary rod vertically fixed to the inner bottom wall of the auxiliary box, and an auxiliary groove opened at the bottom end of the counterweight.

[0013] Furthermore, the number of auxiliary rods is ≥5 and they are distributed in a linear array on the inner bottom wall of the auxiliary box. The number of auxiliary slots is the same as the number of auxiliary rods, and the auxiliary rods are located directly below the auxiliary slots.

[0014] The beneficial effect of adopting the above-mentioned further solution is that the auxiliary fixing component can effectively prevent the counterweight from shifting position.

[0015] Furthermore, the outer side of the curtain wall glass is coated with a fire-retardant coating, the fuse has a melting temperature of 80-100℃, and the fire-retardant curtain fabric comprises a glass fiber base fabric and a ceramicized silicone rubber composite layer.

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] In the embodiments, by Figure 1-5 Provided is a fireproof curtain wall, comprising two parallel steel structure supports 1 and a curtain wall glass 2 fixed between the two steel structure supports 1. A fixed shell 3 located on the front side of the curtain wall glass 2 is fixedly connected between the two steel structure supports 1. A rotating column 4 that can rotate around an axis is provided on the inner side of the fixed shell 3. A counterweight 6 is installed on the inner side of the fixed shell 3 through a fuse 5. A fireproof curtain 7 is fixedly connected to the outer side of the rotating column 4, and the other end of the fireproof curtain 7 is fixedly connected to the outer side of the counterweight 6. The width of the fireproof curtain 7 matches the width of the curtain wall glass 2. Under normal conditions, the fireproof curtain 7 is rolled up on the rotating column 4. When a fire occurs, the high temperature melts the fuse 5, releasing the counterweight 6 and causing the fireproof curtain 7 to unfold and cover the surface of the curtain wall glass 2.

[0020] The fireproof curtain 7 system, which can be automatically deployed as described above, can quickly form a second fire barrier in the event of a fire, effectively solving the problem that traditional curtain wall glass 2 is prone to cracking at high temperatures. Moreover, the width of the fireproof curtain 7 matches that of the curtain wall glass 2 to ensure complete coverage and protection.

[0021] In this embodiment, limit sliders 8 are symmetrically arranged on both sides of the counterweight 6, forming a sliding guide structure that precisely matches the limit sliding holes 9 machined on the inner side of the steel structure bracket 1. The matching of the limit sliders 8 and the limit sliding holes 9 ensures that the falling trajectory of the counterweight 6 is precise and controllable. In addition, a pushing component 10 is fixedly connected to the inner side of the steel structure bracket 1, which is in contact with the top surface of the limit sliders 8. The pushing component 10 provides additional downward power to ensure that the fireproof curtain 7 can be deployed quickly and smoothly.

[0022] In this embodiment, the pushing component 10 consists of a fixed plate 101 welded and fixed and a pre-compressed pushing spring 102. The free end of the pushing spring 102 always keeps in contact with the top surface of the limiting slider 8. After the fuse 5 melts, it immediately releases elastic potential energy to push the limiting slider 8 down.

[0023] By utilizing the elastic potential energy of the push spring 102, the counterweight 6 is ensured to obtain sufficient initial acceleration, significantly shortening the deployment response time of the fireproof curtain 7.

[0024] In this embodiment, an auxiliary fixing component 11 is also included. The auxiliary fixing component 11 includes an auxiliary box 111 fixedly connected between two steel structure supports 1. An auxiliary rod 112 is vertically fixed to the inner bottom wall of the auxiliary box 111, and an auxiliary groove 113 is provided at the bottom end of the counterweight 6.

[0025] Among them, the number of auxiliary rods 112 is ≥5 and they are distributed in a linear array on the inner bottom wall of the auxiliary box 111. The number of auxiliary slots 113 is the same as the number of auxiliary rods 112, and the auxiliary rods 112 are located directly below the auxiliary slots 113, ensuring that the positions of each auxiliary rod 112 and the auxiliary slot 113 are precisely corresponding to ensure smooth insertion.

[0026] The auxiliary rod 112 and the auxiliary groove 113 are used to fix the fireproof curtain 7 after it is unfolded, so as to prevent the fireproof curtain 7 from shifting due to wind or vibration. The multiple sets of plug-in structures evenly distribute the force and avoid local stress concentration, which can effectively improve the stability of the fireproof curtain 7 and prevent its position from shifting.

[0027] In this embodiment, the surface of the curtain wall glass 2 is coated with a transparent fireproof coating to improve the initial fire resistance performance. A specific fuse 5 with a melting point between 80-100℃ is selected to ensure timely response. The fireproof curtain 7 is made of glass fiber base cloth combined with ceramicized silicone rubber to form a high-temperature resistant composite structure.

[0028] Working principle: When a fire occurs and the fire spreads to the vicinity of the entire device, the curtain wall glass 2 can provide the first layer of protection against the fire. At the same time, the fire will heat the steel structure support 1 and transfer the heat to the fixed shell 3. As the temperature of the fixed shell 3 continues to rise, when it reaches the melting point of the fuse 5, the fuse 5 will break. Under the combined force of the pushing spring 102 and the gravity of the counterweight 6, the fireproof curtain 7 will be pulled out until the auxiliary rod 112 is inserted into the inner side of the auxiliary groove 113, thereby restricting the position of the fireproof curtain 7 to the outside of the curtain wall glass 2, so that the fireproof curtain 7 completely covers the curtain wall glass 2. When the curtain wall glass 2 breaks at high temperature, it can not only prevent the curtain wall glass 2 from flying, but also provide secondary protection against fire through the fireproof curtain 7, greatly extending the time for the fire to spread.
