Description
Technical Field
[0001] This utility model relates to the field of PVC window technology, and in particular to a double thermal break fire-resistant passive window for a five-constant system. Background Technology
[0002] PVC windows, following wood, iron, and aluminum alloy windows, were actively promoted by the government in the mid-1990s. Due to their lower price and good performance-price ratio, they are still widely used. The frames of these windows are made primarily of polyvinyl chloride resin, with added stabilizers, colorants, fillers, and UV absorbers, extruded into profiles; they are one of the most commonly used window types in modern architecture.
[0003] For example, the authorization announcement number "CN222759674U" describes a passive PVC fire-resistant window that can be replaced simply by pulling out the glass through the large and small moving frames, which greatly saves costs and improves the convenience and safety of window replacement.
[0004] However, existing passive PVC fire-resistant windows still have other problems in use. For example, existing passive PVC fire-resistant windows use a single thermally broken aluminum to achieve the functions of sound insulation, flame retardancy, and heat insulation. Fire-resistant windows need to have high fire resistance and heat insulation conditions. The single thermally broken aluminum structure cannot fully block heat conduction and transfer. In hot summer weather, heat will be conducted through the relatively small connection points at the edge of the thermal break, reducing the heat insulation performance of the passive PVC fire-resistant window.
[0005] Meanwhile, existing passive PVC fire-resistant windows use a pull-out disassembly method for glass replacement and installation. However, the entire fire-resistant window glass pull-out replacement device will result in many structural seams and small gaps on the inside of the window. This will not only conduct heat and cause air and water leakage, but also allow thick smoke from the fire to seep into the room through the gaps left for glass replacement in the event of a fire, thus reducing the fire resistance performance of the passive PVC fire-resistant window. Summary of the Invention
[0006] This invention aims to solve the problems existing in the prior art by providing a double-thermal-break fire-resistant passive window for a five-constant system, which can improve thermal insulation performance and fire resistance.
[0007] The technical solution adopted by this utility model to solve its technical problem is as follows:
[0008] Design a double-thermal-break fire-resistant passive window for a five-constant system, including a passive window frame, anti-collision corner protectors, and an operable window sash. The operable window sash is rotatably connected to the inside side of the passive window frame via hinges. Multiple anti-collision corner protectors are fixedly installed on the outer corners of the passive window frame. A fixed window sash is movably installed at the other end of the inner side of the passive window frame. The inner side of the passive window frame is provided with a double-thermal-break isolation structure. The inner wall of the passive window frame is provided with a triple-glazed support structure. The outer side of the fixed window sash is provided with a sealed fireproof structure.
[0009] Further improvements include a double-brake isolation structure comprising isolation walls and filling blocks. Multiple isolation walls are fixedly connected to the inner side of the passive window frame. Multiple dustproof blocks are fixedly installed inside the multiple isolation walls. A first-level protrusion is fixedly installed in the middle of the inner wall of the isolation wall. A first-level bridge is movably engaged with the inner side of the multiple first-level protrusions. A second-level protrusion is fixedly installed on the inner side of the other end of the isolation wall. A second-level bridge is movably engaged with the inner side of the second-level protrusion. Multiple filling blocks are fixedly installed inside the multiple first-level bridges.
[0010] Further improvements include the parallel and equidistant distribution of multiple first broken bridges, with the outer side of the dustproof block closely attached to the inner front wall of the passive window frame.
[0011] Further improvements include a three-layer glass support structure comprising a sealing strip and an edging. The sealing strip is fixedly installed in the middle of the inner wall of the passive window frame. Multiple sealing strips are fixedly installed at the top of the sealing strips. Glass plates are movably connected to the inner walls of two sealing strips. The edging is fixedly installed on the rear side of the inner wall of the passive window frame. The inner side of the edging is tightly fitted with the edge of the sealing strip. A cavity is fixedly opened above the sealing strip.
[0012] Further improvements include the arrangement of multiple glass panels that are parallel and equidistant from each other, with the edges of the multiple glass panels being movably engaged with the inner wall of the passive window frame.
[0013] Further improvements include a sealing and fireproof structure comprising pressing strips and triangular blocks. Multiple pressing strips are movably pressed against the outer edge of the fixed window sash, and multiple triangular blocks are fixedly installed around the outer perimeter of the fixed window sash. A leak-proof layer is fixedly pressed onto the inner side of the multiple triangular blocks, and multiple reinforcing blocks are fixedly installed on both sides of the leak-proof layer.
[0014] To further improve the design, a window handle switch is fixedly installed on the side wall of the opening window sash.
[0015] The beneficial effects of this utility model are as follows: In this utility model, multiple first-level protrusions are made of aluminum alloy material, and a first thermal break made of rubber material can be inserted into the recessed groove on the inner side. The first thermal break can separate the inner and outer sides of the aluminum alloy passive window frame, achieving the effect of flame retardancy, heat insulation and heat preservation. Similarly, a second-level protrusion made of aluminum alloy material is used near the inside of the passive window frame. A second thermal break made of rubber material is inserted into the inner side of the second-level protrusion. The second thermal break further separates the inner interior part of the passive window frame from the isolation wall part separated by the first thermal break, which can form a secondary heat blockage and effectively improve the protective heat insulation performance.
[0016] The clamping strip is a trapezoidal strip made of natural rubber. The fixed window sash is embedded inside the passive window frame and secured by silicone sealant injected into the clamping strip. The triangular block is made of thin aluminum alloy plate, and its shape matches the four corners of the fixed window sash. This allows the sides of the triangular block to hold the four corners of the fixed window sash in place, thus securing and limiting the window sash. The leak-proof layer consists of multiple layers of interlaced sealing foam filling the gaps between the fixed window sash and the passive window frame. The fixed window sash is firmly installed inside the passive window frame and cannot be removed, but it effectively isolates heat conduction and smoke from entering the room during a fire, thus improving its fire resistance.

[0027] The double-thermal insulation structure 6 includes insulation walls 61 and filling blocks 65. Multiple insulation walls 61 are fixedly connected to the inner side of the passive window frame 1. The insulation walls 61 are made of aluminum alloy. The cross-section of the insulation walls 61 on the inner side of the passive window frame 1 presents multiple irregularly shaped perforations, which can separate the warm cavity and cold cavity inside the passive window frame 1. Multiple dustproof blocks 62 are fixedly installed inside the multiple insulation walls 61. The dustproof blocks 62 are made of lightweight sponge material, which can prevent external dust from penetrating into the internal cavity of the insulation walls 61 of the passive window frame 1. A first-level protrusion 63 is fixedly installed in the middle of the inner wall of the insulation wall 61. Multiple first-level protrusions 63 are made of aluminum alloy. A rubber first thermal break 64 can be inserted into the recessed groove on the inner side.

The inner side of 63 is movably connected to the first thermal break 64. The other end of the isolation wall 61 is fixedly installed with the second-level protrusion 66. The inner side of the second-level protrusion 66 is movably connected to the second thermal break 67. Similarly, the second-level protrusion 66 is made of aluminum alloy near the inside of the passive window frame 1. The second thermal break 67 is made of rubber and is inserted into the inner side of the second-level protrusion 66. The second thermal break 67 further separates the inner interior part of the passive window frame 1 from the isolation wall 61 part separated by the first thermal break 64, which can form a secondary heat blockage and effectively improve the protective heat insulation performance. Multiple filling blocks 65 are fixedly installed on the inner side of multiple first thermal breaks 64. The filling blocks 65 are made of sound insulation cotton with equal pressure structure. The filling blocks 65 can absorb noise to achieve the effect of noise reduction. Multiple first thermal breaks 64 are distributed parallel to each other at equal intervals.

The edging 72 is fixedly installed on the rear side of the inner wall of the passive window frame 1 and is made of artificial rubber. Black adhesive strips cut from adhesive material are attached to the outside of the sealing strip 74 as edging 72. The sealing strip 74 embeds the inner glass panel 75 into the passive window frame 1 to form an opening window sash 4 and a fixed window sash 5. The inner side of the edging 72 is tightly attached to the edge of the sealing strip 74. A cavity 73 is fixedly opened above the sealing strip 71. The cavity 73 is a vacuum cavity in the reserved space, which has the function of reducing the weight of the window and blocking the heat conduction.

The leak-proof layer 82 is a series of interlaced sealing foams that fill the gaps between the fixed window sash 5 and the passive window frame 1. The fixed window sash 5 is firmly installed and embedded inside the passive window frame 1 and cannot be removed, but it can effectively isolate the heat conduction and smoke from entering the room, thus improving its fire resistance. Multiple reinforcing blocks 83 are fixedly installed on both sides of the leak-proof layer 82.
[0030] Working principle:
[0031] The double thermal break fire-resistant passive window used in the "Five Constants System" refers to constant temperature, constant humidity, constant oxygen, constant cleanliness, and constant quietness, which creates an unprecedentedly comfortable and healthy indoor environment. The Five Constants System is used to comprehensively improve five major performance aspects of a building: air tightness, noise reduction, thermal insulation, safety, and heat resistance. The double thermal break fire-resistant passive window here can meet the requirements of the Five Constants System in terms of air tightness, noise reduction, thermal insulation, safety, and heat resistance.
[0032] The openable window sash 4 can be manually opened along one side of the passive window frame 1, making it convenient to open the window for ventilation. The anti-collision corner protector 2 is an arc-shaped corner protector made of multiple foam sponge materials. It is pasted on the corners during the transportation and handling of the passive window frame 1 to prevent collision damage. The anti-collision corner protector 2 needs to be removed before the passive window frame 1 is installed inside the reserved hole in the wall. The fixed window sash 5 is a larger window fixed on the other side of the passive window frame 1. It cannot be opened at will and mainly serves the functions of light transmission, view, wind and rain protection.
[0033] The partition wall 61 is made of aluminum alloy. The cross-section of the partition wall 61 inside the passive window frame 1 features multiple irregularly shaped perforations, effectively separating the warm and cold cavities within the passive window frame 1. The dustproof block 62 is made of lightweight sponge material, preventing external dust from penetrating into the internal cavity of the partition wall 61. Multiple first-level protrusions 63 are made of aluminum alloy, and rubber first thermal break 64 can be inserted into the recessed grooves on their inner sides. The first thermal break 64 separates the inner cavity of the aluminum alloy passive window frame 1. On both sides, flame retardant, heat insulation and heat preservation effects are achieved. Similarly, near the inside of the passive window frame 1, a second-level protrusion 66 is made of aluminum alloy material. The second-level protrusion 66 is filled with a second thermal break 67 made of rubber material. The second thermal break 67 further separates the indoor part of the passive window frame 1 from the isolation wall 61 part separated by the first thermal break 64, which can form a second heat blockage and effectively improve the protection and heat insulation performance. The filling block 65 is made of sound insulation cotton material with equal pressure structure. The filling block 65 can absorb noise to achieve the effect of noise reduction.
[0034] The sealing strip 71 is made of rubber material and separates the space where the glass plate 75 is installed from the lower thermally broken aluminum part. The sealing strip 74 is a circle of glass glue around the outer wall of the glass plate 75. The edging 72 is a black rubber strip cut from artificial rubber material. The edging 72 is attached to the outside of the sealing strip 74. The sealing strip 74 embeds the inner glass plate 75 into the passive window frame 1 to form an opening window sash 4 and a fixed window sash 5. The inner side of the edging 72 is close to the edge of the sealing strip 74. The cavity 73 is a vacuum cavity in the reserved space, which has the function of reducing the weight of the window and blocking the heat conduction.
[0035] The pressing strip 81 is a trapezoidal strip made of natural rubber. The fixed window sash 5 is installed and embedded inside the passive window frame 1, and is fixed by injecting glass glue into the pressing strip 81. The triangular block 84 is made of aluminum alloy in a thin metal plate. The shape of the triangular block 84 matches the four corners of the fixed window sash 5. In this way, the side of the triangular block 84 can lock the four corners of the fixed window sash 5, so as to achieve the function of fixing and limiting the fixed window sash 5. The leak-proof layer 82 is a series of interlaced sealing foams that fill the gaps between the fixed window sash 5 and the passive window frame 1. The fixed window sash 5 is firmly installed and embedded inside the passive window frame 1 and cannot be removed, but it can effectively isolate the heat conduction and smoke from entering the room, thus improving its fire resistance.
[0036] Although the present invention has been illustrated and described with reference to preferred embodiments, those skilled in the art should understand that various changes in form and detail are possible within the scope of the claims.
