Description

Technical Field

[0001] The utility model relates to the technical field of fireproof glass, in particular to a composite fireproof glass. Background Art

[0002] With the progress of society and the rapid development of the construction industry, high-rise buildings emerge in an endless stream. As buildings are getting taller and taller, the requirements for building glass materials are also getting higher and higher. All kinds of safety glass and special glass have gradually come into people's vision. The main function of fireproof glass in fire prevention is to control the spread of fire or isolate smoke. It is a measure-type fireproof material, and its fireproof effect is evaluated by its fire resistance performance. It is a special glass that is processed and treated through special processes and can maintain its integrity and heat insulation in the specified fire resistance test. The original sheet glass of fireproof glass can be selected from float flat glass or tempered glass. The composite fireproof glass can also be made of single-piece fireproof glass.

[0003] The composite fireproof glass has good fireproof performance. The fireproof glass is composed of two or more pieces of flat glass and a fireproof adhesive layer sandwiched between the flat glasses. When a fire occurs, the fireproof adhesive layer absorbs a large amount of heat generated by the fire and quickly foams and expands to form an insulating fireproof and heat-insulating foam layer. However, when the fireproof adhesive layer absorbs heat and expands, it is easy to generate direct stress on the glass on both sides, and there is a risk of glass breakage. In addition, the installation of traditional fireproof glass is relatively cumbersome, resulting in inconvenience during replacement. Therefore, to solve the above problems, we propose a composite fireproof glass. Summary of the Utility Model

However, when the fireproof adhesive layer absorbs heat and expands, it is easy to generate direct stress on the glass on both sides, and there is a risk of glass breakage. In addition, the installation of traditional fireproof glass is relatively cumbersome, resulting in inconvenience during replacement.

[0006] (2) Technical Solutions

[0007] To achieve the above objectives, the utility model is realized through the following technical solutions:

[0008] A composite fireproof glass, comprising a first composite glass, a second composite glass and a mounting frame. A fireproof adhesive layer is provided between the first composite glass and the second composite glass. A fireproof rubber strip is provided between the first composite glass and the second composite glass, and the fireproof rubber strip surrounds the periphery of the fireproof adhesive layer. The first composite glass, the second composite glass, the fireproof adhesive layer and the fireproof rubber strip are all arranged inside the mounting frame. Four rotating plates are rotatably mounted at the side ends of the mounting frame. Slide rods are slidably sleeved at the side ends of the four rotating plates. Limiting pads are fixedly mounted at the side ends of the four slide rods. Springs are fixedly mounted at the side ends of the four limiting pads. Pull handles are fixedly mounted at the side ends of the four slide rods. The first composite glass and the second composite glass are symmetrically installed. The four springs are fixedly connected to the rotating plates respectively. The four mounting frames are respectively arranged at the four corners of the mounting frame. The four limiting pads are all in effective contact with the second composite glass.

[0009] Preferably: Both the first composite glass and the second composite glass include an anti-ultraviolet layer, a heat-insulating layer, a heat-preserving layer, a fireproof glass layer, a film layer and a sound-insulating layer. The side end of the anti-ultraviolet layer is fixedly connected to the side end of the heat-insulating layer. The side end of the heat-insulating layer is fixedly connected to the side end of the heat-preserving layer.

[0010] Preferably: The side end of the heat-preserving layer is fixedly connected to the side end of the fireproof glass layer. The side end of the fireproof glass layer is fixedly connected to the side end of the film layer. The side end of the film layer is fixedly connected to the side end of the sound-insulating layer.

[0011] (III) Beneficial effects

[0012] First, when the fireproof adhesive layer expands, it squeezes the second composite glass. The second composite glass is stressed and squeezes the heat-insulating layer. The limiting pad is stressed and squeezes the spring. The spring is stressed and deforms. By installing limiting pads and springs on the outer side of the composite fireproof glass, during the use of the composite fireproof glass, when the fireproof adhesive layer is heated and expands, it drives the second composite glass to displace. The spring contracts through the limiting pad to perform shrinkage compensation, thereby improving the stability of the composite fireproof glass during use.

[0013] Second, release the pull handle. The spring resets and drives the limiting pad to squeeze and limit the second composite glass, so as to achieve the purpose of limiting and fixing the first composite glass and the second composite glass. By installing rotating plates that can rotate and retractable limiting pads on the mounting frame of the composite fireproof glass, during the process of replacing the first composite glass and the second composite glass, the quick disassembly of the first composite glass and the second composite glass can be realized, effectively improving the replacement work efficiency, thereby improving the practicability.

The general idea is as follows:

[0023] In view of the problems existing in the prior art, the utility model provides a composite fireproof glass, which comprises a first composite glass 1, a second composite glass 11 and a mounting frame 2. A fireproof glue layer 18 is arranged between the first composite glass 1 and the second composite glass 11. A fireproof glue strip 19 is arranged between the first composite glass 1 and the second composite glass 11. The fireproof glue strip 19 surrounds the periphery of the fireproof glue layer 18. The first composite glass 1, the second composite glass 11, the fireproof glue layer 18 and the fireproof glue strip 19 are all arranged inside the mounting frame 2. Four rotating plates 21 are rotatably installed at the side ends of the mounting frame 2. Slide rods 22 are slidably sleeved at the side ends of the four rotating plates 21. Limit pads 23 are fixedly installed at the side ends of the four slide rods 22. Springs 24 are fixedly installed at the side ends of the four limit pads 23. Pull handles 25 are fixedly installed at the side ends of the four slide rods 22. Among them, the first composite glass 1 and the second composite glass 11 are symmetrically installed. The four springs 24 are fixedly connected to the rotating plates 21 respectively. The four mounting frames 2 are respectively arranged at the four corners of the mounting frame 2. The four limit pads 23 are all in effective contact with the second composite glass 11.

[0024] Both the first composite glass 1 and the second composite glass 11 include an anti-ultraviolet layer 12, a heat-insulating layer 13, a heat-preserving layer 14, a fireproof glass layer 15, a film layer 16 and a sound-insulating layer 17.

[0025] Working principle:

[0026] First step, when the composite fireproof glass is in use, pull the handle 25. The handle 25 drives the sliding rod 22 under force. The sliding rod 22 drives the limit pad 23 under force. The limit pad 23 squeezes the spring 24 under force. The spring 24 deforms under force. Then pull the handle 25 to deflect. The handle 25 drives the rotating plate 21 to deflect in angle. Pull it to one side of the installation frame 2. Then place the assembled composite glass one 1 and composite glass two 11 into the installation frame 2. Pull the handle 25 to drive the rotating plate 21 to reset. The reset of the rotating plate 21 drives the limit pad 23 to reset. Then release the handle 25. The reset of the spring 24 drives the limit pad 23 to squeeze and limit the composite glass two 11, so as to achieve the purpose of limiting and fixing the composite glass one 1 and the composite glass two 11. In case of danger, the fireproof adhesive layer 18 absorbs a large amount of heat generated by the fire when heated, and quickly foams and expands to form an insulating fireproof and heat-insulating foam layer. When the fireproof adhesive layer 18 expands, it squeezes the composite glass two 11. The composite glass two 11 squeezes the heat-insulating layer 13 under force. The limit pad 23 squeezes the spring 24 under force. The spring 24 deforms under force. By installing the limit pad 23 and the spring 24 on the outside of the composite fireproof glass, during the use of the composite fireproof glass, the expansion of the fireproof adhesive layer 18 drives the displacement of the composite glass two 11, and the contraction of the spring 24 is driven by the limit pad 23 for shrinkage compensation, thereby improving the stability of the composite fireproof glass during use.

[0027] Second step, when the composite fireproof glass is in use, during the process of continuously replacing the composite glass one 1 and the composite glass two 11, pull the handle 25 to drive the sliding rod 22. Further, the sliding rod 22 drives the limit pad 23 to squeeze the spring 24 under force. The spring 24 deforms under force. Then pull the handle 25 to deflect. The handle 25 drives the rotating plate 21 to deflect in angle. Pull it to one side of the installation frame 2. Then remove the composite glass one 1 and the composite glass two 11 from the installation frame 2 and replace them. After that, pull the handle 25 to drive the rotating plate 21 to reset. The reset of the rotating plate 21 drives the limit pad 23 to reset. Then release the handle 25. The reset of the spring 24 drives the limit pad 23 to squeeze and limit the composite glass two 11, so as to achieve the purpose of limiting and fixing the composite glass one 1 and the composite glass two 11. By installing the rotatable rotating plate 21 and the retractable limit pad 23 on the installation frame 2 of the composite fireproof glass, during the process of replacing the composite glass one 1 and the composite glass two 11, quick disassembly of the composite glass one 1 and the composite glass two 11 can be realized, effectively improving the work efficiency of replacement, thereby improving the practicability.

[0028] Finally, it should be noted that: Obviously, the above embodiments are only examples given to clearly illustrate the present utility model, rather than limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or modifications derived therefrom still fall within the protection scope of the present utility model.
