Abstract
Description
Technical Field
[0001] This invention relates to the field of doors and windows, and in particular to a steel profile fireproof glass frame system. Background Technology
[0002] Aluminum alloy doors and windows are widely used in the market, with advantages such as light weight, easy processing, high durability, and easy maintenance. However, they also have certain application drawbacks, such as poor energy-saving and heat-insulating effects, environmental impact, poor noise insulation, and insufficient fire resistance. However, it is more important for aluminum alloy doors and windows to distinguish whether the fire source comes from the outside or the inside. If it comes from the inside, the better the sealing effect of the window, the more likely it is that the people inside will suffocate due to insufficient oxygen. If it comes from the outside, it is necessary to protect the people inside the house from contact with the smoke coming from the outside. Therefore, aluminum alloy doors and windows need to respond in a targeted manner according to different fire source directions.
[0003] Therefore, we propose a steel profile fireproof glass frame system to solve the above problems. Summary of the Invention
[0004] The purpose of this invention is to provide a steel profile fireproof glass frame system to solve the problems mentioned in the background art. The technical solution of this invention addresses the problem that the existing technical solutions are too simplistic and provides a solution that is significantly different from the existing technology.
[0005] To achieve the above objectives, the present invention provides the following technical solution:
[0006] A fire-resistant glass frame system using steel profiles includes a door frame and a door leaf. Fire-resistant glass is installed in the middle of the door leaf. Fire-resistant expansion strips are installed on the outer walls of the door frame and the door leaf. A fracture strip is connected to one side of the fire-resistant expansion strip. A first metal sheet and a second metal sheet are connected to one side of the fracture strip. Elastic fire-resistant fabric is connected to the edges of the first and second metal sheets. The elastic fire-resistant fabric, the first metal sheet, and the second metal sheet constitute a fully sealed structure. A counterweight is provided at the connection between the door frame and the door leaf. A plug is installed on one side of the first metal sheet.
[0007] In a further embodiment, both the interior of the door frame and the interior of the door leaf are filled with fireproof inserts.
[0008] In a further embodiment, the fully sealed structure consisting of the elastic fireproof fabric, the first metal sheet, and the second metal sheet is located in the gap at the connection between the door frame and the door leaf, and the counterweight is located above and supported by the fully sealed structure consisting of the elastic fireproof fabric, the first metal sheet, and the second metal sheet.
[0009] In a further embodiment, the thickness of the fireproof expansion strip gradually increases from top to bottom, and the counterweight is a trapezoidal structure.
[0010] In a further embodiment, a circular recess is installed on one side of the first metal sheet, and the first metal sheet is connected to the insertion rod through the circular recess. A breakthrough layer is formed in the middle of the second metal sheet, and a support member is installed on one side of the second metal sheet. The support member and the insertion rod are slidably connected.
[0011] In a further embodiment, the fire-resistant expansion strip is distributed on both sides of the sealing structure formed by the elastic fire-resistant fabric, the first metal sheet, and the second metal sheet, and the first metal sheet and the second metal sheet are connected to the fire-resistant expansion strip on either side by a fracture strip.
[0012] In a further embodiment, both the first metal sheet and the second metal sheet have arc-shaped cross-sections, and the first metal sheet and the second metal sheet have the same bending direction.
[0013] Compared with the prior art, the beneficial effects of the present invention are:
[0014] The feature of this application is that it can respond to fires occurring in different locations. When a fire occurs outside, the sealing structure in this device can improve the sealing of large gaps at the hinge of the door frame and door leaf through the natural expansion of the internal gas and the fireproof expansion strip. When a fire occurs inside, the sealing structure can quickly leak air when it senses heat, allowing the counterweight to fall quickly downwards. The door leaf is forcibly opened by the counterweight compression, which plays a role in ventilation and avoids the accumulation of a large amount of smoke indoors.
[0015] Secondly, the door leaf and door frame structure of this application are welded together, unlike the traditional horizontal and vertical frames connected by simple screws, which easily makes the seams visible on the surface. In the steel profile system of this application, the horizontal and vertical frames are welded into one piece, then ground and sprayed to achieve a seamless finish. At the same time, this steel profile system uses 35mm thick FFB-A1.50 composite fireproof glass, which has superior fire resistance integrity, fire resistance and heat insulation, and greatly improves safety.

Thus, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this invention, unless otherwise stated, "a plurality of" means two or more.
[0023] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art will understand the specific meaning of the above terms in this invention based on the specific circumstances.
[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0025] Example 1: Please refer to Figure 1-5In this embodiment of the invention, a steel profile fireproof glass frame system includes a door frame 1 and a door leaf 2. Fireproof glass 3 is installed in the middle of the door leaf 2. Fireproof expansion strips 5 are installed on the outer walls of the door frame 1 and the door leaf 2. A fracture strip 6 is connected to one side of the fireproof expansion strip 5. A first metal sheet 7 and a second metal sheet 9 are connected to one side of the fracture strip 6. Elastic fireproof fabric 8 is connected to the edges of the first metal sheet 7 and the second metal sheet 9. The elastic fireproof fabric 8, the first metal sheet 7 and the second metal sheet 9 constitute a fully sealed structure. A counterweight 11 is provided at the connection between the door frame 1 and the door leaf 2. A plug rod 10 is installed on one side of the first metal sheet 7. Fireproof plug cores 4 are filled inside the door frame 1 and the door leaf 2. The fireproof plug cores 4 are made of ceramic fiber and calcium silicate board composite.
[0026] Example 2: Please refer to Figure 1-5 The difference from Embodiment 1 is that the fully sealed structure composed of the elastic fireproof fabric 8, the first metal sheet 7, and the second metal sheet 9 is located in the gap at the connection between the door frame 1 and the door leaf 2. The counterweight 11 is located above and supported by the fully sealed structure composed of the elastic fireproof fabric 8, the first metal sheet 7, and the second metal sheet 9. The counterweight 11 is supported by a gas-filled sealed structure. The elastic fireproof fabric 8, the first metal sheet 7, and the second metal sheet 9 are all located at the pivot point. When the counterweight 11 falls downwards, the entire door leaf structure can be opened.
[0027] A circular recess 701 is installed on one side of the first metal sheet 7, and the first metal sheet 7 is connected to the insertion rod 10 through the circular recess 701. A breakthrough layer 901 is opened in the middle of the second metal sheet 9, and a support member 902 is installed on one side of the second metal sheet 9. The support member 902 and the insertion rod 10 are slidably connected. The circular recess 701 is a protrusion with a pit, which can be engaged with the insertion rod 10. The breakthrough layer 901 is made of fire-resistant and brittle material, which can be broken by the insertion rod 10. In order to improve the efficiency of gas release, holes can be opened on the surface of the insertion rod 10 to allow the gas in the sealed structure to flow out quickly in a short time, or the size of the insertion rod 10 and the breakthrough layer 901 can be enlarged to increase the exhaust volume in a short time. The support member 902 can be slidably connected with the insertion rod 10 to ensure that the insertion rod 10 is stably aligned with the breakthrough layer 901.
[0028] The fire-resistant expansion strips 5 are distributed on both sides of the sealing structure formed by the elastic fire-resistant fabric 8, the first metal sheet 7, and the second metal sheet 9. The first metal sheet 7 and the second metal sheet 9 are connected to the fire-resistant expansion strips 5 on either side through the fracture strips 6. The fire-resistant expansion strips 5 can expand during preheating. At the same time, the fracture strips 6 are connected to the sides of the sealing structure to ensure the long-term stability of the sealing structure. Preferably, the sealing structure is connected to the fire-resistant expansion strips 5 on the door frame 1, so that the sealing structure will not be affected when the door leaf 2 rotates, and the sealing structure will not rotate with it.
[0029] The first metal sheet 7 and the second metal sheet 9 both have arc-shaped cross-sections. The first metal sheet 7 and the second metal sheet 9 bend in the same direction. The fact that the first metal sheet 7 and the second metal sheet 9 are both arc-shaped ensures that they gradually bend after thermal expansion. The first metal sheet 7 and the second metal sheet 9 need to be made of metal materials that expand rapidly after heating.
[0030] Example 3: Please refer to Figure 1-5 The difference from Embodiment 1 is that the fireproof expansion strip 5 gradually increases in thickness from top to bottom, and the counterweight 11 has an overall trapezoidal structure. The purpose of the fireproof expansion strip 5 gradually thickening from top to bottom is to give the counterweight 11 a certain squeezing effect when it falls, forcing the door leaf 2 to open outward.
[0031] The working principle of this invention is:
[0032] The door leaf 2 of this application is a rotating door leaf 2, which opens inward. In the event of a fire indoors, the first metal sheet 7 is heated first, and the second metal sheet 9 is heated later. The first metal sheet 7 bulges outward more violently when heated, thereby pressing the insertion rod 10, allowing the insertion rod 10 to be inserted into the penetration layer 901. The penetration layer 901 is a fireproof thin sheet structure, which will be damaged by the external force of the insertion rod 10, causing air leakage inside. Ultimately, the entire sealing structure leaks air rapidly, causing the uppermost counterweight 11 to lose support and move downward. The force of the fall causes multiple fracture strips 6 to break rapidly, causing the entire sealing structure to collapse. The counterweight 11 moves downward. Since the fireproof expansion strip 5 gradually thickens from top to bottom, the counterweight 11 compresses the door frame 1 and the door leaf 2, forcing the door leaf 2 to open and improving the internal ventilation efficiency.
[0033] When a fire occurs outdoors, the second metal sheet 9 will be heated first because the heat source is from the outside. The first metal sheet 7 will be heated laterally. The second metal sheet 9 will be heated and bulge outwards. During the bulging process, it will pull the insert rod 10 laterally and gradually disengage the insert rod 10 from the inside of the circular concave point 701. This will cause one end of the insert rod 10 to lose its support point and rely solely on the support member 902 for support. In this way, the insert rod 10 cannot be aligned with the penetration layer 901. Even if the problem caused by the fire intensifies and the first metal sheet 7 expands outwards due to heat, it will not push the insert rod 10 to break through the penetration layer 901. The entire sealing device will not leak air. Moreover, as the temperature increases, the gas expansion effect will be greater, making it easier to block the gap at the pivot of the door frame 1 and the door leaf 2, preventing smoke and fire from spreading inwards. In order to improve the fireproof effect, the outer sides of the first metal sheet 7 and the second metal sheet 9 are coated with a fireproof coating.
[0034] Both the door frame 1 and the door leaf 2 profile frames are made of two steel plates that are rolled together to hold nylon strips and stainless steel sheets, and then fireproof expansion sealing strips are pasted longitudinally along the joint.
[0035] Meanwhile, to improve the stability of natural closing and opening, the bottom of the counterweight 11 can be glued to the bottom of the sealing structure to prevent accidental tipping.
[0036] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
[0037] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
