Description

TECHNICAL FIELD

[0001] The utility model relates to glass partition heat insulation technical field, concretely is a kind of glass partition with fireproof heat insulation performance. BACKGROUND

[0002] Glass partition is a kind of space separating device made of transparent or translucent glass material, with functionality and aesthetics, it can effectively divide indoor area, maintain lighting transparency, and can also improve the modern sense of space, and is widely used in office, commercial and home environment.

[0003] Composite heat-insulating fireproof glass is usually composed of two or more layers of glass original piece and one or more layers of fireproof adhesive interlayer, when fire occurs, the glass on the fire surface is quickly cracked after high temperature, the fireproof adhesive interlayer is foamed and expanded by about ten times, and a large amount of heat generated by flame burning is absorbed, forming white opaque fireproofing.

[0004] However, after the above-mentioned fireproof glass cracks on the fire surface, the fireproof adhesive interlayer will slowly flow downward due to the action of gravity during foaming and expansion, and if the gel flows downward due to gravity before the gel layer is fully expanded into a heat-insulating foam layer, the fireproofing and heat-insulating performance of the part will be weakened, and high-temperature heat may penetrate through this weak area, affecting the overall fire resistance integrity and heat-insulating stability. UTILITY MODEL CONTENTS

[0005] The utility model aims at providing a glass partition with fireproofing and heat-insulating performance to solve the problems raised in the background art.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: a glass partition with fireproofing and heat-insulating performance, comprising a partition glass, a connecting assembly is arranged on the side wall of the partition glass, and the connecting assembly comprises:

[0007] A connecting frame is provided with a mounting slot on the top end face, a connecting piece is inserted into the side wall of the connecting frame, and an air duct is fixedly connected to the inner wall of the connecting frame.

[0008] A sealing plate is inserted into the connecting frame, and a sealing gasket is fixedly connected to the side wall of the sealing plate.

[0009] Preferably, the mounting slot is arranged in a stepped manner, the partition glass is inserted into the mounting slot, and the inner wall of the mounting slot abuts against the partition glass.

[0010] Preferably, one end of the air duct is arranged on the top end face of the connecting frame, and the other end of the air duct is arranged on the side wall of the connecting frame.

[0011] Preferably, the side wall of the connecting frame is provided with a slot, the slot is inserted into the sealing plate, the air passage is located at one end of the side wall of the connecting frame and is opened on the inner wall of the slot, the sealing gasket is interference fit with the inner wall of the slot, and the sealing gasket blocks one end of the air passage.

[0012] Preferably, there are two sets of connecting brackets, and the two sets of connecting brackets are fixedly connected by plug-in connectors. The connecting brackets and connectors are interference-fitted, so that the two sets of connecting brackets are tightly fixed together.

[0013] Preferably, each set of connecting frames has two sets of mounting slots on its top end face, and each set of mounting slots is inserted into the partition glass. The air duct is located at one end of the top end face of the connecting frame between the two sets of partition glass on the same set of connecting frames. The space between the two sets of partition glass on the same set of connecting frames is filled with hydrated silicate, which is a fireproof adhesive interlayer. When exposed to fire, the water in the hydrated silicate evaporates rapidly and carries away a large amount of heat. At the same time, the material foams and expands to form an opaque white foam insulation layer, preventing heat and flames from penetrating. A vacuum is drawn between the glass on the two sets of connecting frames. The vacuum can block the transfer of heat, thereby improving the heat insulation performance of the glass partition.

[0014] Preferably, the inner wall of the mounting groove is fixedly connected with an adhesive pad, which is in contact with the partition glass, and the adhesive pad is a strip made of flexible material.

[0015] Compared with the prior art, this utility model provides a glass partition with fireproof and heat insulation properties, which has the following beneficial effects:

[0016] 1. This fire-resistant and heat-insulating glass partition, through its connecting components, has a hydrated silicate adhesive interlayer between the two outermost sets of partition glass. The vacuum layer has almost no heat-conducting medium, which greatly reduces heat conduction and heat convection. In the early stages of a fire, the high-temperature radiant heat from the fire-facing side first penetrates the outer glass, but is significantly blocked by the vacuum layer. When the fire-facing glass breaks, the hydrated silicate adhesive interlayer absorbs heat and evaporates moisture, carrying away a large amount of heat. At the same time, it foams and expands to form a dense foam structure, improving heat insulation. Before the glass completely shatters, an early foaming layer is formed around the perimeter, controlling the expansion in stages to prevent the adhesive layer from sagging and flowing down. This early edge sealing forms a fire-resistant expansion sequence from the edges to the center, limiting the spread of flames and high-temperature gases through the frame and enhancing overall heat insulation and airtightness.

[0017] 2. This fire-resistant and heat-insulating glass partition reduces the contact area between the glass and the connecting components through the setting of the bonding pad, thereby improving the effective performance of the entire glass partition. The flexible bonding pad fits tightly, which can seal the gaps in the installation groove, prevent moisture from spreading along the edge, and prevent the continuous evaporation of moisture in the hydrated silicate fireproof interlayer.

[0023] like Figures 1-4 As shown, this utility model provides a technical solution: a glass partition with fireproof and heat insulation properties, including a partition glass 1, and a connecting component 2 is provided on the side wall of the partition glass 1. The connecting component 2 includes a connecting frame 201, a mounting groove 202, a connector 203, an air duct 204, a sealing plate 205, and a sealing gasket 206.

[0024] In one embodiment of this utility model, the top end face of the connecting frame 201 is provided with a mounting groove 202. The mounting groove 202 is stepped, so that the mounting groove 202 can be adapted to partition glass 1 of different thicknesses. The partition glass 1 is inserted into the mounting groove 202, and the inner wall of the mounting groove 202 abuts against the partition glass 1. A connector 203 is inserted into the side wall of the connecting frame 201. An air passage 204 is fixedly connected to the inner wall of the connecting frame 201. One end of the air passage 204 is opened on the top end face of the connecting frame 201, and the other end of the air passage 204 is opened on the side wall of the connecting frame 201.

[0025] The sealing plate 205 is inserted into the connecting frame 201. A sealing gasket 206 is fixedly connected to the side wall of the sealing plate 205. A slot is opened on the side wall of the connecting frame 201. The slot is inserted into the sealing plate 205. One end of the air passage 204 is located on the inner wall of the slot. The sealing gasket 206 is interference-fitted with the inner wall of the slot. The sealing gasket 206 blocks one end of the air passage 204.

[0026] Two sets of connecting brackets 201 are provided. The two sets of connecting brackets 201 are fixedly connected by plug-in connectors 203. The connecting brackets 201 and the connectors 203 are interference-fitted, so that the two sets of connecting brackets 201 are tightly fixed together. The top end face of each set of connecting brackets 201 has two sets of mounting grooves 202. Each set of mounting grooves 202 is plugged into the partition glass 1. One end of the air channel 204 is located on the top end face of the connecting bracket 201 and is set between the two sets of partition glass 1 on the same set of connecting brackets 201. The space between the two sets of partition glass 1 on the same set of connecting brackets 201 is filled with hydrated silicate. The hydrated silicate is a fireproof adhesive interlayer. When exposed to fire, the water in the hydrated silicate evaporates rapidly and takes away a large amount of heat. At the same time, the material foams and expands to form an opaque white foam insulation layer, which prevents heat and flames from penetrating. Vacuum is drawn between the glass on the two sets of connecting brackets 201. Vacuuming can block the transfer of heat, thereby improving the heat insulation performance of the glass partition.

[0027] Four sets of partition glass 1 are arranged side by side by the connecting frame 201. The space between the two middle sets of partition glass 1 is evacuated, while the space between the two outer sets of partition glass 1 is filled with a hydrated silicate adhesive interlayer. The vacuum layer has almost no heat-conducting medium, which can greatly reduce heat conduction and heat convection. In the early stage of a fire, the high temperature radiant heat from the fire-facing side first penetrates the outer glass, but the heat transfer is greatly blocked by the vacuum layer. When the glass on the fire-facing side breaks, the hydrated silicate adhesive interlayer absorbs heat and evaporates moisture, taking away a large amount of heat. At the same time, it foams and expands to form a dense foam structure, which improves the heat insulation and plays a role in blocking radiant heat and fireproof separation. Multiple cavities are set in the connecting frame 201 and the connecting piece 203. The cavities are equivalent to artificially increasing the thermal resistance inside the connecting frame 201 and the connecting piece 203, breaking the thermal bridge channel between the metal parts, reducing the overall heating rate of the metal to a certain extent, and reducing the risk of thermal expansion, bending, and cracking.

[0028] The sealing plate 205 is made of PE material, which melts rapidly when exposed to flames, allowing the water vapor in the hydrated silicate adhesive interlayer to be discharged through the air channel 204. This causes the surrounding adhesive interlayer to expand rapidly. When the glass on the fire-facing side breaks, the middle adhesive interlayer foams and expands again, forming an early foaming layer around the perimeter before the glass completely shatters. This phased expansion control prevents the adhesive layer from sagging and flowing down, and seals the edges in advance, forming a fire-resistant expansion sequence from the edges to the center. This restricts the spread of flames and high-temperature gases through the frame, enhancing the overall heat insulation and airtightness.

[0029] In addition, an adhesive pad 3 is fixedly connected to the inner wall of the mounting groove 202. The adhesive pad 3 is attached to the partition glass 1. The adhesive pad 3 is a strip made of flexible material. The adhesive pad 3 improves the sealing performance between the partition glass 1 and the connecting frame 201, reduces the contact area between the glass and the connecting component 2, slows down the speed at which heat is transferred from the connecting frame 201 to the glass interlayer, and improves the heat insulation performance of the entire glass partition. The hydrated silicate fireproof interlayer is very sensitive to environmental humidity. If the edge is not sealed well, moisture will easily evaporate at room temperature, causing the interlayer to dry out, age, and reduce its foaming ability. The flexible adhesive pad 3 fits tightly and can seal the gaps in the mounting groove 202, preventing moisture from spreading along the edge.

[0030] In this invention, during use, the connecting frame 201 arranges four sets of partition glass 1 side by side. The space between the two middle sets of partition glass 1 is evacuated, while the space between the two outer sets of partition glass 1 is filled with a hydrated silicate adhesive interlayer. The vacuum layer has almost no heat-conducting medium, which greatly reduces heat conduction and heat convection. In the early stages of a fire, the high-temperature radiant heat from the fire-facing side first penetrates the outer glass, but the vacuum layer significantly blocks heat transfer. When the glass on the fire-facing side breaks, the hydrated silicate adhesive interlayer absorbs heat and evaporates moisture, carrying away a large amount of heat. At the same time, it foams and expands to form a dense foam structure, improving heat insulation and playing a role in blocking radiant heat and fireproof separation. The sealing plate 205 melts rapidly when it encounters flames, allowing the water vapor in the hydrated silicate adhesive interlayer to be discharged through the air passage 204, which in turn causes the surrounding adhesive interlayer to expand rapidly. When the glass on the fire-facing side breaks, the middle adhesive interlayer foams and expands again, forming an early foaming layer around the perimeter before the glass completely shatters. The expansion is controlled in stages to prevent the adhesive layer from sagging and flowing down as a whole.

[0031] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
